Embodiment Construction

[0038] The method and system of the present invention will be further elaborated below in conjunction with the accompanying drawings of the description.

[0039] The implementation method of the PoC service provided by the present invention is as follows: firstly, a corresponding relationship table between the PoC user identification and the PoC server to which it belongs is established, and the identification information of the PoC user and the address information of the PoC server to which it belongs are stored in the corresponding relationship table. The correspondence table may be stored in an address server, and the address server provides PoC server address query and resolution functions.

[0040] In the address server, corresponding to each PoC user, there is a user identifier, and the user identifier may be the PoC user's International Mobile Subscriber Identity code, or the PoC user's Uniform Resource Identifier (URI).

[0041] The address information of the PoC serve...

Abstract

The invention discloses a PoC service implementation method, which establishes a corresponding relationship table between a PoC user identifier and a PoC server; when a PoC user initiates a call, the following steps are performed: A. Initiate a call request message to the PoC server, and the call is received B. The calling PoC server queries the corresponding relationship table according to the called user identification information, and obtains the information of the PoC server to which the called party belongs; C. The calling PoC server sends a call request to the called PoC server, and the called party The PoC server establishes a connection with the called user to implement call connection. The PoC service implementation system provided by the present invention includes a user terminal with PoC service capability, a PoC server, and an address server that stores a correspondence table between PoC user identifiers and the PoC server they belong to.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and system for realizing a push-to-talk voice service (PoC service) on a cellular system. Background technique [0002] PTT (Push to Talk) is a half-duplex communication technology that communicates by pressing function keys. At present, it includes many implementation methods, such as iDEN (Integrated Digital Enhanced Network, integrated digital enhanced network) and Tetra (Terrestrial Trunked RAdio, digital trunking mobile communication). PoC (PTT over Cellular) is a PTT service implemented on a packet network defined by OMA (Open Mobile Alliance). It uses packet voice (VoIP) and half-duplex. The PoC service has the following characteristics: [0003] 1) There is no need to dial a number when talking, just press and hold the special key to realize voice communication; [0004] 2) Multicast can be realized, one person speaks, and multiple people listen at the sam...
