Presence Service in IMS
This paper describes the presence service, which is located in the IP multimedia subsystem. This service allows making many applications for different groups of people. The paper describes differences between a network without the service and with the service. The biggest change is an increased number of transmitted messages. The presence uses some part of the IP multimedia subsystem control la...
متن کاملIMS Based Mobile Presence Service
One of the key factors associated with mobile data services is the ability to provide greater contextualization of user activity through information such as personal presence. One of the barriers to the provision of context information for services operating over mobile phone networks has been the inflexibility of the existing architecture which has its roots in voice services. The aim of IMS i...
متن کاملAdmission Control Approaches in the IMS Presence Service
In this research, we propose a weighted class based queuing (WCBQ) mechanism to provide class differentiation and to reduce the load for the IMS (IP Multimedia Subsystem) presence server (PS). The tasks of admission controller for the PS are demonstrated. Analysis and simulation models are developed to quantify the performance of WCBQ scheme. An optimized dropping time frame has been developed ...
متن کاملIntegrating IMS Presence Information in a Service Oriented Architecture
Successful service delivery platforms will need to build on service oriented architectures and provide interoperability with the IP Multimedia Subsystem (IMS). In this extended abstract we describe how presence information that is maintained in IMS can be integrated into a service oriented architecture.
متن کاملA Critical Evaluation of the IMS Presence Service
The IP Multimedia Subsystem (IMS) defined by the 3rd Generation Partnership Projects (3GPP) is a standardized architecture for the Next Generation Network. In this paper, we provide an insight into the presence service, one of the fundamental building blocks of the IMS. Our prototype-based study is unique of its kind and helps identifying the factors which limit the scalability of the current v...
