A network system and method for displaying service based on IMS

Abstract

The utility model relates to a network system and method for realizing IMS-based presence business. The improved system is characterized in that the relatively independent presence server PS and the presence list server PLS arranged in respective IMS domains respectively are combined to merge into a new piece of equipment: presence business application server. The equipment is directly connected with the service call session control function S-CSCF entity in the IMS core network to simultaneously complete all the work done by prior two servers. The utility model presents the structural composition and functions of the internal modules of the presence business application server. At the same time, new presence business process is presented based on the system. The utility model provides the same functions as the prior business systems, but the network functional entity in the prior framework is reduced, and the total information in the presence business system is effectively reduced, such as domain amount and inter-domain information amount. The SIP dialogue numbers requiring maintenance of the presence server PS and presence list server PLS are simultaneously reduced, which significantly eases the pressure on network bandwidth and server processing performance.

Description

technical field [0001] The present invention relates to a technical improvement scheme for the existing system architecture based on the IP multimedia subsystem IMS network to realize the presentation service, to be precise, relates to a network system and method for realizing the presentation service based on the IMS on the 3G mobile communication network , belonging to the technical field of business and its application in the third generation communication system or telecommunication system. Background technique [0002] With the development of 3G technology, the IP Multimedia Subsystem IMS proposed by the Third Generation Partnership Project (3GPP) has been identified by the industry as the core technology of the NGN control plane and service plane. The presence service is a new type of communication service that obtains presence information (such as user status, communication capabilities, personal reference, etc.) in real time according to the set access criteria in a ...

[0012] (2) The SIP message is a text-based signaling message, and the presence information message body it carries is also a standard Extensible Markup Language XML document. Through calculation, it can be concluded that the total bandwidth and peak bandwidth required to transmit these messages are relatively This is also one of the main reasons for the high pressure on network bandwidth
