METHOD AND SYSTEM FOR TERMINAL PTT REGISTRATION BASED ON CDMA TRUNKING SYSTEM
First Claim
1. A method of terminal PTT registration based on CDMA trunking system, comprising:
- Step S102, after a PTT terminal is powered and a normal CDMA registration flow is completed, the value of a PTT registration message counter of the PTT terminal is initialized;
Step S104, the PTT terminal initiates a registration to a dispatching server and sends a PTT registration message to a base station on a control channel through the PTT registration message;
Step S106, after having sent the PTT registration message, the PTT terminal starts a PTT registration timer of the terminal and waits for a registration response message from the base station;
Step S108, upon having received the PTT registration message of the PTT terminal user, the base station sends to the terminal a registration response message containing answer information;
Step S110, if the registration response message received by the PTT terminal is a PTT registration acceptance message of the base station, then it goes to Step S114;
if the registration response message received by the PTT terminal is a PTT registration refusal message of said the base station, then it goes to Step S118;
if the PTT terminal has not received the response message from the base station when the PTT registration timer expires, it goes to S112;
Step S112, the value of the PTT registration message counter is assigned by subtracting the current value of the registration message counter by 1 wherein if the value of the PTT registration message counter is greater than 0, then the PTT terminal returns to S104, re-sending the PTT registration message to the base station, otherwise it turns to S116;
Step S114, the registration succeeds and the PTT terminal shuts down the PTT registration timer, finishing the registration;
Step S116, the registration does not succeed and the PTT registration timer is shut down, finishing the registration; and
Step S118, the registration is failed and the PTT registration timer is shut down, finishing the registration.

Abstract
The present invention provides a method of terminal PTT registration based on CDMA trunking system and the system thereof, comprising: a user terminal is powered and a normal CDMA registration flow is completed, and afterwards the value of a PTT registration message counter is initialized; the user terminal sends a PTT registration message to a dispatching sub-system (server) and starts a PTT registration timer; and a corresponding process is performed according to the response message from the dispatching server, which is the reception of the trunking registration or the rejection of the trunking registration. Therefore the terminal with CDMA trunking function can avoid the problem caused by a failed PTT registration.

18. A terminal PTT registration system based on CDMA trunking system, comprising:
-
a registration device for providing a PTT registration message to a base station, answering a response message from the base station, and counting the execution times of the PTT registration message; the base station for sending the PTT registration message from the registration device to a dispatching server and forwarding the response message from the dispatching server to the registration device; the dispatching server for receiving the PTT registration message from the base station and sending to the base station the response message as the processing result of trunking function; and a transmission channel for transmitting the PTT registration message. - View Dependent Claims (19, 20, 21, 22)
