V. (FORM4) EXECUTIVE SUMMARY ON RESEARCH OUTCOMES OF THIS PROGRAM
1.
General Description of the Program: Including Objectives of the Program
In Beyond-3G environments, mobile and wireless networks will be integrated together under an all-IP core network to support global roaming and services. Issues such as mobile security, QoS, and mobility management need to be investigated. For mobile ad hoc and sensor networks, critical issues include power saving, routing, sensing, MAC, and integration with other mobile networks. In terms of application, context-aware services and environmental monitoring applications need to be developed. In PAEU-I, we have made several major contributions. For example, Prof. Y.B. Lin proposed novel 3G core network protocols for mobility management, authentication, fault tolerance, and mobile database overflow control. Due to these contributions, he was awarded IEEE Fellow and ACM Fellow in 2003. The works of Prof. Y.C. Tseng on routing, MAC, and power-saving protocols for ad hoc and sensor networks have been well recognized internationally. Based on this established research energy, in PAEU-II, we have developed B3G all-IP core and access networks, including HSS, CSCF and OSA, and to invent advanced location determination and energy conservation technologies. Specific goals include:
Issues on IP Multimedia Core Network Subsystem such as Fault tolerance of IMS, design and implementation of OSA (service network for IMS), IMS services (including prepaid, Voice over IP, and wireless data), all-IP mobility (including location management and packet re-routing), application-level security (including identity-based cryptosystem and end-to-end security mechanisms for SMS), IMS session management, IMS-related architectures (including WGSN push mechanism, ad-hoc andinfrastructure dual-mode mobile networks, and softswitch).
Issues on Access Networks (i.e., Ad hoc, WLAN/WiMax, and Cellular networks) including , topics on load balance, security and authentication, multi-channel or multi-antenna access points, QoS support for VoIP and location-sensing routing, MAC, power-saving have been investigated. We have also investigated critical issues, such as efficient contention protocols, fast handoff, and resource scheduling. In addition, suitable analytical methodologies for these works also required. By investigating these topics, we expect to make significant contributions to these issues. Due to the fast advance of VoIP services, we will develop novel multi-channel MAC protocols for multi-hop ad hoc networks, and study how to integrate ad hoc networks with mobile VoIP services.
Issues on B3G applications include seamless IP/PLMN integration, P2P technologies, and novel mobile data applications. The integration of IP networks and PLMN has to be done on both the network and the service layers. We have focused on the integration on the service layer, which requires novel designs and has more profound impacts on the user experience. Skype has demonstrated how P2P technologies can be used to provide a world-wide VoIP communication platform. P2P technologies can also be used in other mobile data applications, such as multimedia communications, and device-to-device communications and collaboration.

Figure 2.1 the B3G Network Architecture
Broadband Wireless Access Technologies
This part focuses on access technologies of broadband wireless networks. We have designed a multi-chain backoff (MCB) algorithm which provides high throughput and fair wireless access. We also developed a power-saving scheduling to extend the network lifetime and a hybrid routing method for multi-hop wireless LANs to improve the routing efficiency. The IEEE 802.11 standard defines multiple channels at the physical layer. However, most ad hoc networks assume that all nodes are operating under the same radio channel. To breakthrough the throughput limitation, we have proposed several multi-channel links layer protocols for multi-hop ad hoc networks. In
particular, a lightweight multi-channel MAC protocol characterized by location awareness capability has been proposed. It incurs no communication cost to conduct the channel assignment. Moreover, we have investigated optimization models and efficient algorithms to exploit the maximum channels reusability. In order to improve the network access efficiency and reduce roaming overhead, we have implemented a light-weight access protocol on a centralized WLAN server with thin access points. This centralized WLAN architecture reduces the handoff delay and cuts management overhead significantly. Finally, we have built a mobile ad hoc network across the NTHU and the NCTU campuses. The platform allows us to verify research ideas generated from the project. The ad hoc network is also connected to the core network we developed.
Applications and Services in B3G Networks
We have proposed an architecture to support VoIP services in an Internet-enabled mobile ad hoc network. To reduce power consumption, we have proposed a push mechanism to allow the VoIP gateway to stay off-line when there is no calling activity and to be “woken up” when necessary.

Network System Design of the B3G Core Network
Due to our fruitful results in both PPEAU-I and PPEAU-II, we were invited to guest editing an IEEE Wireless Communications special issue on Mobility and Resource Management published in 2004 [C.1]. By focusing on GPRS/UMTS research issues, we have developed a UMTS discontinuous reception mechanism for power saving [C.2]. We also developed a bandwidth-on-demand strategy for GPRS [C.4]. Based on the above studies, we developed a useful tool NCTUns 2.0 for wireless Internet simulation [C.6] (the major contributor is Prof. S.-Y. Wang in PPEAU-I). We investigated the UMTS short message mechanism and have invented a statistic approach for deriving the short message transmission delay distributions [C.7]. Based on the above study, we developed an efficient multicast mechanism for UMTS through
collaboration with ICL/ITRI, and received ROC Patent 205010 [patent1] (major work in PPEAU-I). In GPRS/UMTS mobility management, we have conducted signaling traffic analysis for multi-tier wireless mobile networks [C.5], and developed a per-user checkpointing for mobility database failure restoration [C.3]. To improve prepaid user experience and protect operator’s revenue, we presented a real-time charging method for prepaid users with integrated voice and data services. An analytic model has been developed to evaluate the performance [C.44].
In Wireless VoIP, we have developed the VoIP services for GSM circuit switched data, GPPRS, and UMTS environments [C.8][C.9]. Through collaboration with ICL/ITRI. We received a patent for wireless VoIP [patent 2] (major work in PPEAU-I). We proposed an effective VoIP call routing mechanism in WLAN and cellular integration [C.35]. To integrate existing VoIP protocols, we developed an integrated call agent that is capable of establishing calls between SIP, H.323, MGCP/MEGACO users [C.45]. In addition, we developed a novel method enable one-stage dialing from the PSTN to a private telephone network and/or an IP telephony network through a VoIP gateway and/or a PBX ([C.126]). We have developed a novel, simple method for a dual-mode device to register with a location registrar the device’s E.164 number and IP address ([C.128]).
By continuing PPEAU-I's work on WGSN, we have developed a mobile service platform using proxy technology [C.11], and a caching mechanism in I-CSCF of UMTS IP multimedia subsystem (IMS) [C.12]. Then we developed a GPRS-based WLAN authentication and auto-configuration for WGSN [C.13]. We further investigated the IMS authentication defined in 3GPP, and proposed an one-pass GPRS and IMS authentication procedure for WGSN. We developed the first connection failure detection mechanism of UMTS charging protocol [C.16], and the first checkpointing schemes for UMTS mobility database failure restoration [C.25]. We collaborated with ITRI to develop the first CORBA-based OSA service platform in Taiwan [C.18], devised the first credit allocation algorithm for UMTS services [C.19], and consistent wireless data access algorithms [C.36,C.37].We proposed a serving radio network controller relocation for UMTS all-IP network [C.20], investigated the impact of mobility on UMTS mobile telecommunications networks [C.21, C.23,C.24, C.26], and invented a novel random number generation for excess life of mobile user residence times [C.22,C.25]. We developed a fast identity-based cryptosystem mechanism for end-to-end mobile security [C.27] and applied this mechanism for SMS end-to-end security [C.28].
We designed and implemented a UMTS session management tool for he user equipment [C.29], and proposed new schemes for frame synchronization for UMTS HSDPA [C.30]. We also investigated IP connectivity for gateway GPRS support node [C.31].
In [C.58] we studied checkpointing and failure restoration of mobility database for Universal Mobile Telecommunications System (UMTS). By utilizing per-user checkpointing technique, individual Home Subscriber Server (HSS) records are saved into non-volatile backup storage form time to time. When a failure occurs, the backup record is restored back to the mobility database. We consider three per-user checkpoint schemes for the HSS. An analytic model is developed to investigate these schemes in terms of the probability that a HSS backup record is obsolete. This model is validated against simulation experiments. Our study provides guidelines for selecting an appropriate checkpoint scheme and parameters for various traffic conditions. In UMTS, the security function provides mutual authenticity and key agreement between the core network and the Mobile Station (MS). Specifically, the Serving GPRS Support Node (SGSN) in the core network obtains an array of Authentication Vectors (AVs) from the HSS/Authentication Center AuC), and consumes one AV for each mutual authentication. After the departure of the MS, the SGSN may keep the unused AVs for a time interval called the Reservation Timeout (RT) period. If the MS returns within the RT period, the SGSN uses the stored AVs for mutual authentication instead of obtaining new AVs from the HSS/AuC. Note that a long RT period results in fewer accesses to the HSS/AuC at the cost of extra AV storage in the SGSN. In [C.66], we proposed an analytic model to investigate the impact of the RT period on the system performance. Our study provides the guidelines for the mobile operators to select an appropriate RT period. The 3GPP defines IP Multimedia Core Network Subsystem (IMS) to support IP-based multimedia services. In IMS, any incoming call will first arrive at the Interrogating Call Session Control Function (I-CSCF). The I-CSCF queries the HSS to identify the serving CSCF (S-CSCF) of the called mobile user. The S-CSCF then sets up the call to the called mobile user. In [C.68], we investigated the performance of the IMS incoming call setup. We also proposed cache schemes with fault tolerance to speed up the incoming call setup process. Our study indicates that the I-CSCF cache can significantly reduce the incoming call setup delay, and checkpointing can effectively enhance the availability of I-CSCF.
In [C.88], we studied the optimum checkpointing interval of per-user checkpointing for mobility database failure restoration. The cost function that we consider includes the cost of checkpointing a user’s location record and the cost of
paging a user due to an invalid location record. Our results indicate that when user registration intervals are exponentially distributed, the user record should never be checkpointed if the expected checkpointing cost is more than the expected paging cost,. Otherwise, if paging costs more, the user record should always be checkpointed when a user registers.
IMS utilizes protocols such as IPv6, Session Initiation Protocol (SIP) and
Real-time Transport Protocol (RTP) to deliver the multimedia content. In [C.59] we
proposed an analysis tool called SIPv6 Analyzer to investigate the IMS-related protocols during IMS service deployment. The SIPv6 Analyzer not only dissects the protocol headers but also provides user-friendly functions such as message flow generation, and audio/video replay for IPv6, SIP and RTP. In IPv6-based IMS, a user equipment (UE) may not be allowed to roam or hand off from UMTS to a private-IPv4 GPRS network. In [C.65], we utilized SIP mobility and an automatic IPv6 tunneling mechanism, called Teredo, to support roaming/handoff of a UE between different networks. We have developed the first non-commercial Linux-based Teredo mechanism, and compared our solution with other Teredo implementations in the public domain. Our solution can reduce the tunneling overhead and transmission delay over two other implementations by 44%-74%. By tunneling IPv6 packets over IPv4 UDP, Teredo supports IPv4/IPv6 dual-stack nodes in private IPv4 networks behind Network Address Translation (NAT) to access IPv6 networks. However, the current Teredo protocol does not work with symmetric NAT. In [C.65] we proposed SymTeredo, an extension of Teredo with capability to traverse the symmetric NAT. Our extension preserves the Teredo architecture, and offers backward compatibility with the original Teredo protocol. The above results are utilized in an international collaboration with INT at France.
In [C.61] we proposed a client architecture for the Push to Talk over Cellular (PoC) service based on the Open Mobile Alliance (OMA) PoC specifications v1.0 release. We showed that most standard VoIP modules can be reused for the PoC client, and the VoIP software can be easily extended to support PoC service. A PoC client prototype has been implemented in the Industrial Technology Research Institute (ITRI) and National Chiao-Tung University (NCTU) Joint Research Center.
Through Recharge Threshold-based Credit Reservation (RTCR) mechanism, prepaid IMS services can be supported by the Online Charging System (OCS) in UMTS. In RTCR, when the remaining amount of prepaid credit is below a threshold, the OCS reminds the user to recharge the prepaid account. It is essential to choose an appropriate recharge threshold to
reduce the probability that the in-progress service sessions are forced-terminated. In [C.60] we developed an analytic model to investigate the performance of RTCR for OCS. Based on our study, the network operator can select the appropriate parameter values for various traffic conditions. In [C.62] we proposed a prepaid application server to handle both the prepaid calls and messaging services in IMS. When both voice and messaging are simultaneously offered, delivery of a message during a call may result in force-termination of that call due to credit depletion. To address this issue, we described a strategy to determine if a prepaid message can be sent out during a call session. We proposed an analytic model to investigate the performance of this strategy. Our study provides guidelines to select appropriate input parameters for the prepaid application server. In UMTS, a user may be engaged in multiple voice and/or data prepaid sessions at the same time. For such services, it is important to distribute appropriate amounts of prepaid credit units to simultaneously executed sessions of a user. [C.70] studied the credit allocation for the prepaid sessions. To simultaneously accommodate more prepaid sessions for a user, we proposed a credit reclaim mechanism called Prepaid Credit Reclaim (PCR). Analysis and simulation experiments are conducted to investigate the performance of our mechanism. Our study indicates that PCR can significantly improve the performance of the prepaid mechanism. In UMTS, the extension of GPRS tunneling protocol called GTP' is utilized to transfer the Charging Data Records (CDRs) from GPRS Support Nodes (GSNs) to Charging Gateways (CGs). To ensure that the mobile operator receives the charging information, availability for the GTP' transmission is essential. One important issue on GTP' availability is connection failure detection. It is desirable to select appropriate parameter values to avoid false failure detections (e.g., temporary network congestions) while to detect the true failures quickly. In [C.70], we proposed an analytic model to compute the false failure detection probability and the expected true failure detection time. Based on our study, the network operator can select the appropriate parameter values for various traffic conditions to reduce the probability of false failure detection and/or true failure detection time. The above results have been transferred to TL/CHT.
In a mobile telecommunications network, the period when an MS resides in a cell (the radio coverage of a base station) is called the cell residence time of that MS. The period between when a call arrives at the MS and when the MS moves out the cell is called the excess life of the cell residence time for that MS. In performance evaluation of a mobile telecommunications network, it is important to derive the excess life distribution from the cell residence times. This distribution determines if a connected call will be handed over to a new cell, and therefore significantly affects the call dropping probability of the network. In mobile telecommunications network simulation, generating the excess-life random numbers is not a trivial task, which has not been addressed in the literature. In [C.22], we showed how to
generate the random numbers from the excess life distribution, and developed the excess-life random number generation procedures for cell residence times with gamma, Pareto, lognormal and Weibull distributions. Our study indicated that the generated random numbers closely match the true excess-life distributions.
In the next generation mobile telecommunications, any third party that provides wireless data services (e.g., mobile banking) must have its own solution for end-to-end security. Existing mobile security mechanisms are based on public-key cryptosystem. The main concern in a public-key setting is the authenticity of the public key. This issue can be resolved by identity-based (ID-based) cryptography where the public key of a user can be derived from public information that uniquely identifies the user. In [C.28], we proposed an efficient ID-based encryption algorithm. We actually implemented the ID-based encryption schemes and compare the performance to show the advantage of our approach. Our solution outperforms a previously proposed algorithm by 20 -- 35%.
Broadband Wireless Access Technologies
In the access technologies on WLAN, the IEEE 802.11 standard adopts the binary exponential backoff (BEB) for collision avoidance. This approach may significantly degrade the network performance if contention window size is dramatically changed after each successful transmission degrades the network performance. In [C.54], we proposed a multi-chain backoff (MCB) algorithm which explores the possibility of using multiple backoff chains with different minimum contention windows and considering collision events on the wireless channel as hints to choose a proper chain. With the capability of switching to different backoff chains, our study shows that MCB offers higher throughput than the existing protocols, such as GDCF, IEEE 802.11, MILD, EIED, and LILD, yet still provides fair access to the wireless channel. In [C.96], we have also proposed a Fast Handoff Mechanism for IEEE 802.11 and IAPP networks, which can significantly reduce wireless handoff latency in IEEE 802.11 WLANs. In addition, a new power-saving method for WLAN is also developed [C.40]. On the other hand, with the increasing popularity of voice over WLAN (VoWLAN) services, there is a need to guarantee QoS for voice calls while supporting as many calls as possible. In [C.95], we propose a call admission control (CAC) and a resource adjustment (RA) mechanism to solve the handoff and resource redistribution issues over IEEE 802.11e wireless networks. The proposed scheme is designed to dynamically adjust the resource distribution among existing calls according to the network condition. Our study shows better utilization of bandwidth, decreased
blocking rate for new calls, and less dropping rate for handoff calls have been achieved by the proposed mechanisms. In [C.103], we have showed how to integrate SIP and 802.11e to conduct call admission control and resource reservation to support VoIP’s QoS in IEEE 802.11e WLANs. We have also suggested some adjustments and MAC enhancements to 802.11e to facilitate VoIP traffics over WLANs. This work received the Best Paper Awards in NCS 2005 [C.216].
In terms of MANETs, we have further proposed a Multi-rate wireless Fair Queuing (MR-FQ) algorithm in [C.55], which allows a flow to transmit at different rates according to its channel condition and lagging degree. MR-FQ takes both time and service fairness into account. It not only guarantees fairness and bounded delays for packet flows but also increases the overall system throughput. In [C.64], we have proposed several cluster-based semi-asynchronous power-saving protocols for multi-hop MANETs. We showed how to cluster neighboring hosts such that synchronous power-saving protocols can be adopted within individual clusters, and asynchronous power-saving protocols can be adopted between clusters. In [C.27], we provides an analytic tool to evaluate the expected throughput of the route with spectral reuse, assuming that hosts move following the discrete-time, random-walk model by a given routing path. Because while many routing protocols have been proposed for MANETs based on different criteria, few have considered the impact of multi-rate communication capability that is supported by many current WLAN products. The derived result can also be added as another metric for route selection. We proposed a hybrid routing method that combines the advantages of Hierarchical Routing Tree (HRT) and Ad-hoc On-demand Distance Vector (AODV) routing for multi-hop wireless LANs [C.38]. A ring based information collection architecture were presented to improve the power efficiency for wireless ad hoc sensor networks [C.42]. In wireless ad hoc networks, constructing and maintaining a topology with lower nodes degrees is usually intended to mitigate excessive traffic load on wireless nodes. However, keeping lower nodes degrees often prevents nodes from choosing better routes that consume less energy. Therefore, a tradeoff is between the node degree and the energy efficiency. In [C.19], an adjustable structure, named the r-neighborhood graph, is proposed to control the topology. This structure has the flexibility to be adjusted between the two objectives To construct this structure, we have investigated a localized algorithm, named PLA, consuming less transmitting power during construction and execute efficiently in O(nlogn) time..
The wireless mesh network (WMN) attracts lots of interest as a new broadband Internet access technology. However, increasing throughput is still an open and
challenging research issue. One potential solution is to utilize multiple channels dynamically. However, most existing works do not consider the routing issue but use some popular single-path routing protocols, such as AODV and DSR. In [C.102], we propose a novel protocol named Joint Multi-channel and Multi-path control (JMM) to investigate the benefit of multi-path routing in multi-channel WMNs from the aspect of end-to-end throughput. By dividing the time into slots, JMM coordinates channel usage among slots and schedules traffic flows on dual paths. Our study shows that JMM efficiently decomposes contending traffics over different channels, different time, and different paths, and hence leads to significant throughput improvement (more than 240%). To the best of our knowledge, this is the first work discussing the joint design of multi-channel control and multi-path routing for WMNs. Single-channel medium access control (MAC) protocols are usually adopted for wireless communication among MSs. However, as the number of MSs increases, the performance of such protocols degrades quickly due to collision/contention. In [C.56], we developed a lightweight MAC protocol for a multi-channel MANET called GRID, which is characterized by location awareness capability. GRID incurs no communication cost to conduct the assignment. Our study indicates that GRID is effective under both the fixed-channel-bandwidth and the fixed-total-bandwidth wireless environments. In [C.48] and [C.56], we have proposed multi-channel MAC protocols for multi-hop ad hoc networks. We proposed a novel MAC protocol with on-demand channel assignment for multi-hop ad hoc networks [C.48]. We have developed an efficient MAC protocol for multi-channel mobile ad hoc networks based on location information [C.56]. Then an efficient reliable broadcasting protocol for wireless mobile ad hoc networks has been developed [C.57]. In [C.82], we consider the next-generation wireless mesh networks in which each node may be equipped with multiple radio interfaces, each capable of running in one of several modes, one of several channels, and each capable of supporting multiple modulations. The proposed methodology is based on linear programming with network flow principles and radio channel access/interference models. Given a network topology, traffic requirements, and gateway capacities, we show how to allocate network interface cards and their channels to fully utilize channel bandwidths. In addition, we consider a channel assignment problem for multi-channel multi-radio wireless mesh networks. In [C.99], we formally model the hybrid channel assignment scheme into an integer linear programming formulation. We provide the necessary as well as sufficient conditions of any feasible assignment. We also show that the approximability of the considered problem.
In [C.22], we study how to exploit spectral reuse in resource allocation in an IEEE 802.16 mesh network, which includes routing tree construction, bandwidth
allocation, time-slot assignment, and bandwidth guarantee of real-time flows to meet the need of wide-range broadband wireless access at low cost. The proposed spectral reuse framework covers bandwidth allocation at the application layer, routing tree construction and resource sharing at the MAC layer, and channel reuse at the physical layer. To the best of our knowledge, this is the first work which formally quantifies spectral reuse in IEEE 802.16 mesh networks and which exploits spectral efficiency under an integrated framework.
About the access technologies on cellar networks, we have developed an adaptive mechanism for soft handover in OVSF WCDMA systems in [C.47]. We are the first group to identify the importance of managing OVSF codes in WCDMA systems, which has significant impact on the utilization of the system. Several strategies, such as leftmost and crowded-first schemes, were proposed. [C.52] [C.53]. These works have been used and cited by several other researchers. As the General Packet Radio Service (GPRS) network begins to provide such as ”push-to-talk” (PTT) service, delay-sensitive packets should be given higher priority in transmission. In [C.21], we study two channel allocation schemes that implement priority queues for priority packets in the GPRS network: Bitmap Channel Allocation (BCA) and Uplink State Flag Channel Allocation (USFCA). Our study shows that the transmission delay of priority packets in the GPRS network can be better guaranteed using USFCA. We have also analyzed performance of multi-piconet Bluetooth networks. New analytical methodologies were developed, which can more accurately predict Bluetooth network performance [C.49]. In [C.15] and [C.70] we proposed original overflow control schemes for UMTS high speed downlink packet access. We are the first research team to identify and attack this problem. In order to handle the roaming problem in heterogeneous access technologies, we have proposed a mobility support for mobile host roaming between WLAN and GPRS networks via a handoff decision model to reduce the latency [C.39].
The access technologies can also help developing location systems. A two-phase localization algorithm was also developed for location sensing in wireless sensor networks [C.43]. One challenging issue in sensor networks is to determine where a given sensor node is physically located. This problem is especially crucial for very small sensor nodes. In [C.18], we present a GPS-less, outdoor, self-positioning method for wireless sensor networks. In the optimal transmitting power, the worst-case accuracy for all data points is within 28.87% of the separation-distance between two adjacent reference points (RPs) and the average accuracy is within 15.51%. We have implemented our positioning method on a sensor network test bed and the actual measurement show that the method can achieve average accuracy within 17.9% of the
separation-distance between two adjacent RPs in an outdoor environment. To alleviate Signal strength fluctuation problem in a fingerprint-based localization system, we propose a scrambling method to exploit temporal diversity and spatial dependency of collected signal samples in [C.84]. In wireless Internet applications, we proposed a web content adaptation model which is formulated as a linear multi-choice knapsack problem [C.41]. A dynamic programming method was designed for solving it.
Applications and Services in B3G Networks
Mobile Ad-hoc Network (MANET) is usually considered as a stand-alone network. In [C.14], we propose a two-tier MANET, in which the high-tier gateways are equipped with an additional cellular interface to connect to the Internet. This greatly improves the connectivity of MANET because cellular networks nowadays are almost globally available. To provide seamless roaming capability in private MANET, a modified Mobile IP is implemented in the gateways. We also propose a load-balancing routing protocol to relieve the bottleneck problem of the gateways. In addition, with slight modification, DHCP is adopted in the two-tier MANET to configure the addresses. Considering that connecting to the Internet using cellular interfaces incurs charges and power consumption, we propose a push mechanism to allow the VoIP gateway to stay off-line when there is no calling activities and to be “woken up” when necessary [C.30]. The push approach can save energy and call charges and prevent the MANET subsystem from losing incoming voice calls. In our architecture, we do not modify the SIP server or client architecture. In addition, with few cellular interfaces, the VoIP gateway can serve multiple users inside the MANET concurrently. In next stage, we will address the bandwidth management and call admission control issues for the VoIP gateway.
Prepaid personal communication service (PCS) user has outnumbered post-paid users. In [C.64], we studied the charging issues of an integrated GSM and GPRS prepaid service, where a single prepaid account provides a user both voice and data services. The call setup and charging procedures for GSM and GPRS are presented using the CAMEL network architecture. To reduce the probability of terminating both on-going voice and data calls, we suggest that no new call be admitted when the user credit is below a threshold. An analytic model has been developed to evaluate the performance of the approach. Computer simulations have also been used to verify the simulation results. The numeric results indicate that the forced termination probability can be signicantly reduced by choosing an appropriate threshold of the user credit.
designed a simple, flexible framework for this interworking function [C.23]. The framework is based on a half-call model where a call is controlled by two half-call finite state machines (FSMs), one representing the state of the caller and the other representing the state of the callee. The interworking function has been implemented such that the caller FSM of one VoIP protocol can interact with the callee FSM of any VoIP protocol. The development effort of the interworking function is minimized since only two half-call FSMs for each VoIP protocol are needed and they can be developed independently as long as the design conforms to the same interface specification. We have developed an integrated call agent (ICA) that contains the half-call FSMs of H.323, SIP and MGCP. Calls between devices using these VoIP protocols can be set up, maintained and terminated by the ICAs.
In [C.32], we proposed a UMTS and WLAN interworking solution called WLAN-based GPRS support node (WGSN), which allows a UMTS/WLAN dual mode MS to access heterogeneous wireless services. To reduce the power consumption of an MS, most WGSN applications are not activated at the MS, and MS-terminated services, such as incoming voice over IP (VoIP) calls, are not supported. To address this issue, a push mechanism called session initiation protocol (SIP)-based push center (SPC) was implemented in the WGSN node. For an incoming call to an MS, the SPC utilizes the UMTS short message service to activate the SIP User Agent of the MS. We studied the performance of the SPC. An analytic model was proposed to derive the expected number of lost calls during the activation period. The analytic results are validated against the simulation experiments. Our study quantitatively indicates how the SPC performance is affected by the activation time and the timeout period, and we also suggest how to select appropriate values of these two factors to optimize the SPC performance.
