The Third Generation Partnership Project(3GPP) forum [1] has specified IMS (Internet Protocol Multimedia Subsystem) which provides resource, admission and charging control [2] for multimedia services. The OMA (The Open Mobile Alliance) forum [3] has specified BCAST (Mobile Broadcast Services) [4] which is network agnostic service enabler for mobile broadcast service. Up to now, IMS and BCAST are separated...
IMS, the core architecture of NGN, becomes more and more important in modern telecommunication network. It is the main driving force to promote the evolution of telecommunication technology to "All IP" network. However, it is a big challenge that how to provide carrier grade service on best effort IP network. To solve this problem, SDOs (Standards Development Organizations) have developed...
In this work we present a model for online charging of media-rich services supporting dynamic QoS negotiation, within the third generation partnership project (3GPP) IP multimedia subsystem (IMS) emulated environment. In the QoS negotiation process a user, a network provider, and a service provider negotiate about the session to be initiated, resulting in an user-specific combination of media components...
Internet protocol multimedia subsystem (IMS) was introduced by the third generation partnership project (3GPP) as a horizontal application platform necessary to address the need for a new platform with unified features, common elements, quality of service, open standardized interface for all existing and future multimedia applications and services. IMS is a promising candidate to drive the telecommunication...
IP multimedia subsystem was introduced by the third generation partnership project (3GPP) to enable 3G mobile systems to provide ubiquitous cellular access to all the services that the Internet provides, with improved quality of service, appropriate charging and integration of services. For users to access the IMS services, IMS capable User Equipments are required. In this paper we present an IMS...
Mobile network operators aims are offering new services to be competitive in the telecommunications market. However, the migration cost towards the third generation (3G) network is so high. This paper presents a proposal to offer a next generation services platform based on session initiation protocol (SIP). This solution is easy to implement and its cost is relatively low. Our solution takes into...
