Presently the subscriber is notified regarding the balance by voice or SMS resources, which cannot be billed by the service provider. In this paper authors have presented a novel concept, by which a subscriber is informed his real-time balance without using the above resources. Moreover, the authors have developed a user friendly gui, which looks like the fuel gauge, on the screen of the mobile end point. Furthermore, a subscriber can use various services like voice, video etc. and continue observe the change in his balance on the gauge. The user can also minimize the gauge to the system tray and look for icon changes to indicate changes in the level of the balance. The above ideas have been implemented on a HP iPAQ PDA using Windows Mobile 2005 and tested successfully over a wireless network.","PeriodicalId":301770,"journal":{"name":"2007 International Conference on IP Multimedia Subsystem Architecture and Applications","volume":"303 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115074665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Keeping a product in sync with ever growing requirements is a big challenge and IMS is a classic example for the above statement. 3GPP IMS standards are evolving and the client side requirements bulge every month. It is important to ensure an IMS client is tested during the time of development with a platform that simulates the IMS network. As it is an expensive preposition to rely on operator's live network for testing and a live network cannot simulate error conditions, an IMS client test bed becomes essential. This paper explains our experiences in using open source elements like OpenIMSCore, OpenIKEv2, Strongswan, Open Sigcomp and SIPp to build an IMS client test bed. This paper describes vividly, a test bed that can be used to test an IMS client across usecases that include simple 3GPP call flow, call flow with signaling compression, call flow over TLS, call flow with security and a call flow from a device behind NAT with STUN server. The test bed is built to accommodate IMS clients operating on varied access types like LAN, GPRS/EDGE/UMTS and Wi-FiMtrade.","PeriodicalId":301770,"journal":{"name":"2007 International Conference on IP Multimedia Subsystem Architecture and Applications","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116626208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This wireless evolution to 4G network has the potential to reduce end to end latency and round trip delay, by consolidating and ldquoflatteningrdquo the wireless core network. This network evolution is germane to IMS architecture to support new multimedia services with lower latency characteristics. One of the key service envision to take the market is the high-end real time mobile interactive gaming which is rich in multimedia experience, hence need very stringent real-time/latency requirements. The researches to make Interactive Mobile game the ldquoKiller Applicationrdquo was mainly focused to work around the latency and bandwidth limitations of mobile network. One of the unexplored areas is handling the interworking of mobile services and real time interactive gaming effectively for the multi-vendor, multi platform mobile network. This paper identifies that one of the key challenge in the future mobile gaming is the Service Interaction between games and other mobile services. This paper analyses the gap in the current user equipment based implementations to resolve some of these interworking issues.

There are marked lacks of agreed standards and consistent specifications that influence system architecture design for IMS-capable handsets. To ensure the capacity of convergence in IMS, as more and more applications need support on the handset, performance becomes an increasingly complex demand to satisfy for handset vendors. The problem is even more pronounced when a multi-processor system-on-chip (MPSoC) platform is considered, mainly because of application task mapping onto the MPSoC components and software verification. This paper discusses the situations of mapping application tasks to a heterogeneous MPSoC invoked through managing IMS profiles. It is intended to show a design methodology for MPSoC based IMS handsets as the standardization debate goes on, so that vendors may be poised to leverage upon futuristic market trends to provide the shortest time-to-market all-IMS handset with non-recurrent engineering designs.","PeriodicalId":301770,"journal":{"name":"2007 International Conference on IP Multimedia Subsystem Architecture and Applications","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121333708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Application servers in the IMS service layers are expected to support a open , pluggable environment to add services across vendors and also to share services across application servers. The IMS application servers typically use SIP and DIAMETER as the underlying protocols for communication with other layers and entities within the network.

To meet this objective, it has worked on defining an abstraction of the Access Plane by identifying the interaction requirements between IMS core and access plane and defining interfaces between the two. However, while it was working on this objective, other SDOs, specifically those, that define standards for access technologies, looked at the problem of integrating their access technology with IMS core. They evolved their existing architectures to add IMS components and define interfaces to the access plane elements. These parallel efforts have resulted in multiple architecture definitions that meet the same objectives but differ in their own subtle ways.
