Embodiment Construction

[0051] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0052] figure 1 The PoC initiator client state machine of the first embodiment of the present invention is shown. It includes Initial (initial) state, Creating (creating) state, Created (created) state, Releasing (release) state, Ringing (ringing) state, and Canceling (cancellation) state. The following describes each state one by one:

[0053] Initial state:

[0054]The conference site of the PoC client enters the Initial state after receiving an instruction from the PoC user. The Initial state indicates that the client is in the process of initializing, including creating a session instance. There are two cases here:

[0055] One is that the PoC client constructs and sends a SIP initial session request message to the server after receiving an instruction fro...

Abstract

Present invention relates to communication conversation control technique, discloses a press-and-talk conversation controlling means to correctly realize PoC meeting place state. In said invention, operating conditions unit realizing meeting place status switching between originating side and receiving client-side, combining different kinds of correlative event in PoC conversation, defining multi - state and conversion condition in these state. Said invention provides a practical solution for processing a conversation establishment and fine controlling means for parallel PoC conversation.

Description

technical field [0001] The present invention relates to a session control technology in the communication field, in particular to a session control technology in a push-to-talk (PTT over Cellular, "PoC" for short) based on a cellular network. Background technique [0002] PoC, also known as Wireless Push-to-Talk, introduces direct point-to-point and point-to-multipoint voice communication services in the cellular network. It enables users to enjoy the popular two-way wireless intercom service with mobile phones, and thus promotes mobile services. PoC services can improve the network utilization of mobile operators and greatly increase the throughput of data services, thereby exploring new market opportunities for mobile operators and service providers. [0003] The following is a brief introduction to the principle of PoC: users only need to press one button to start a call. With an "always-on" connection, users can initiate individual and group calls with the touch of a s...
