Embodiment Construction

[0072] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the following description, a detailed description of well-known functions and configurations incorporated herein will be omitted for clarity and conciseness.

[0073] Figure 5 is a schematic diagram illustrating the signal flow related to the concept of sending session participation information through RTCP messages according to the present invention.

[0074] Figure 5 The concept is shown: PoC client A requesting a group session receives the first 200 OK response to establish the group session; receives a SIP response from another PoC client in the same group; and sends the resulting RTCP message to the established session.

[0075] refer to Figure 5 , since the provisional responses received from the PoC clients B1 and B2 as shown in steps S101 and S102 are not final responses for session participation, the conference server CF has a ...

Abstract

Disclosed is a push-to-talk-over-cellular (PoC) service that transmits information on a group talk in a wireless connection section for operation in a mobile environment with a low traffic burden and higher efficiency. The PoC service transmits a PoC call request message of an originating PoC client to a terminating PoC server, receives a response message to the PoC call request message from a terminating PoC client, and receives a message including information of the terminating PoC client transmitting the response message, from an originating PoC server.

Description

technical field [0001] The present invention relates to a push-to-talk-over-cellular (PoC, PoC) communication technology capable of transmitting information about group talk in a wireless connection zone, with a low traffic load and more efficiently operate in a mobile environment, and more particularly, relates to a method and system for sending session participation information of PoC users participating in a PoC group session. Background technique [0002] Significant developments in mobile communication technologies and expansion of mobile communication networks have led to the development of various services and applications for cellular phones. At the same time, the demands of cellular phone users on value-added services such as positioning, multimedia and Push-to-Talk (PTT, push-to-talk) services continue to increase. Among these additional services, the PTT service supports various auxiliary functions such as instant messenger (instant messe...
