Abstract

The invention discloses an IMS network access method using existing equipment. A communication network (100) is described and allows the existing equipment to get access to an IMS network (108). The communication network (100) comprises an exchanging system (104), the IMS network (108) and a non-IMS network (110). The exchanging system comprises a user data base (106), and identities of an IMS user using the existing equipment are prepared in advance. The method includes the steps that in the operating process, a calling party (106) makes a call through the existing equipment (102); the exchanging system receives the call and gets access to the user data base according to identifiers of the calling party (such as a phone number and a URL) so that whether the calling party is the IMS user or not can be judged; if the calling party is the IMS user, the exchanging system will route the call to the IMS network, and if the calling party is not the IMS user, the exchanging system will route the call to the non-IMS network.

Description

[0001] This application is a divisional application of the Chinese patent application "IMS network access using existing equipment" (application date is March 10, 2005) with application number 200510054440.6. technical field [0002] The present invention relates to the field of communications, and in particular to providing access to IMS networks and IMS services using existing equipment. Background technique [0003] As articulated in the 3rd Generation Partnership Project (3GPP), the IP Multimedia Subsystem (IMS) provides a common core network with an access-agnostic network architecture for converged networks. Service providers are embracing this architecture in the evolution of next-generation networks. The IMS architecture was originally defined by the 3GPP to provide multimedia services to mobile users over IP networks. IP network has become the most cost-effective bearer network for transmitting video, voice and data. The IMS uses the advantages of the IP network t...
