Patent ID: 8649279

Claim:
A method for adaptively setting a Timer_Status_Prohibit (TSP) parameter, the method comprising: receiving user device category information from a first terminal, the user device category information indicating a type of user device from among different types of user device; determining a Timer Status Prohibit (TSP) parameter based on the user device category information; transmitting the TSP parameter to the first terminal; transmitting at least one data packet to the first terminal; receiving a status report from the first terminal, the status report transmitted from the first terminal at a time based at least in part on the TSP parameter; using the status report, determining whether there is any missing or erroneously received data packet out of the at least one data packet; retransmitting any missing or erroneously received data packet to the first terminal; measuring a Round Trip Time (RTT) parameter from a data channel; determining an updated Timer Status Prohibit (TSP) parameter based on the RTT parameter; determining whether to transmit the updated TSP parameter based on a comparison of the value of a difference between the updated TSP parameter and the TSP parameter to a predetermined threshold value; and transmitting the updated TSP parameter to the first terminal based at least in part on the determination that the difference value is greater than the predetermined threshold value.
