Problems solved by technology

[0031] As described above, since the registration process must be performed after the communication channel is established, there is a disadvantage that, in the case where the communication channel on the receiving side is not established, it takes a long time until the communication starts, impairing the user's convenience

Abstract

The invention provides a communication server, a communication terminal, and a communication control method thereof. Time required before PoC communication starts, in the case where a communication channel on the destination side has not been established, is shortened, and convenience of users is enhanced. A request for establishing a communication channel used for PoC communication is sent from a terminal TA. Immediately after receiving this request, call processing for establishing a communication channel to a terminal TC other than the terminal TA is started. In parallel with this call processing, processing after sending a response to the request is performed. Thereby, response to a communication channel connection request, SIP Registration processing and Invitation processing on the originating side and the processing on the destination side are performed in parallel, so that connection time can be shortened, and PoC communication can be started early.

Description

technical field [0001] The present invention relates to a communication control server, a communication terminal, and a communication control method, in particular to a communication control server, a communication terminal, and a communication control method that use a packet connection communication channel to provide a SIP session in a mobile communication network. Background technique [0002] Realization of PoC (Push-to-Talk over Cellular) communication is planned. In this communication, a mobile terminal device such as a portable telephone can be used like a radio transceiver, and it can be realized only by touching a button. Communication within a group by multiple people. [0003] PoC communication is a one-to-one or group-to-group rapid communication method, and terminal devices can be used like radio transceivers in PoC communication. The action used to start a session is not pressing a dial button, but something as simple as pressing a specific button. [0004] ...
