Embodiment Construction

[0045] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention.

[0046] IMS terminal UE-A is the chairman of the conference service, and UE-A establishes a bearer of dialog (session) A with UE-B of nonICS UE via eMSC and CSCF. UE-A wants to add UE-B to the conference.

[0047] figure 2 It is the implementation mode of the non-chair party joining the conference business of the present invention, the eMSC initiates and establishes the bearer to the conference server actively, and its specific steps are:

[0048] Step 201, UE-A, as the chairman of the conference, initiates a SIP request (invite) message to the conference server through the CSCF to establish a bearer with the conference server. The SIP request message carries the addre...

Abstract

The invention discloses a method that a non-chairman party enters into a conference service in a centralized service of an IP multimedia system, which can enter a terminal without ICS capacity into the conference service as the non-chairman. The method comprises the following steps: a terminal UE-A with ICS capacity establishes a loading with a terminal without ICS capacity, which are in a connection status; as the chairman party, UE-A convenes a conference establishment and establishes the loading with a conference server, and then instructs UE-B enter into the conference as the no-chairman party, and establishes the loading between an intensified mobile switching center server eMSC and the conference server, and associates UE-B to the established loading between UE-B and UE-A through the eMSC and the conference server, and finally UE-B enters into the conference. The method of the invention can realize the method that the terminal without ICS capacity enters into the conference service as the non-chairman party.

Description

technical field [0001] The invention relates to the communication field, and more specifically relates to a method for joining a conference service by a non-chairman party of an IP multimedia subsystem centralized service. Background technique [0002] IP (Internet Protocol, referred to as IP) multimedia subsystem (IPMultimedia Core Network Subsystem, referred to as IMS) is an IP-based network architecture proposed by the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) , which builds an open and flexible service environment, supports multimedia applications, and provides users with rich multimedia services. [0003] IMS is an IP-based telecommunications network architecture and has nothing to do with access technology, except that it can be used for packet (Packet Switching, PS) access such as GPRS (General Packet Radio Service) and WLAN (Wireless Local Area Network, wireless local area network). In addition to providing services...
