Call processing system and method based on answer mode of push to talk over cellular user
First Claim
1. A call processing system based on a manual answer override (MAO) in a Push-to-Talk over Cellular (PoC) network, the call processing system comprising:
- a transmission side PoC system having a transmission side PoC client and a transmission side PoC server for sending a PoC communication request message to a reception side PoC server, the PoC communication request message including an MAO indication; and
a reception side PoC system having the reception side PoC server for recognizing the MAO indication included in the PoC communication request message received from the transmission side PoC server and sending a response message to the transmission side PoC system in response to the PoC communication request message, and a reception side PoC client for receiving a talk burst signal including the MAO indication from the reception side PoC server.

Abstract
A call processing system and method based on an answer mode of a Push-to-Talk over Cellular (PoC) user are provided. A data format is defined, which inserts an indicator indicating a manual answer override into a payload of a Real-time Transport Control Protocol (RTCP) in a format of a new data field. When a PoC communication requester instructs the MAO to perform PoC communication regardless of an answer mode of a reception side PoC user, an auto-answer mode is immediately executed without any procedure of checking the instruction. In addition, when the reception side PoC user establishes an early session with a home PoC server in its own PoC terminal, the call processing can be performed at a quicker speed.
