Patent ID: 8750861

Claim:
A control apparatus for controlling radio communication, comprising: a communication unit that transfers data; a radio link control unit that performs radio link control; a parameter control unit that sets a parameter to be used for the radio link control; a broadcast information generation unit that generates broadcast information including the parameter set by the parameter control unit; and a pseudo incoming call control unit that performs pseudo incoming call to a communication terminal for a plurality of times after the broadcast information is broadcasted to the communication terminal through the communication unit, to measure a success rate of the pseudo incoming calls using responses to the pseudo incoming calls, wherein the parameter control unit updates the parameter according to the success rate measured by the pseudo incoming call control unit, wherein the parameter control unit changes the parameter, the broadcast information generation unit generates broadcast information including the parameter changed by the parameter control unit, the pseudo incoming call control unit performs the pseudo incoming call for a plurality of times after the broadcast information including the changed parameter is broadcasted by the parameter control unit through the communication unit, and measures a success rate of pseudo incoming calls at different parameters, and wherein the parameter comprises at least one of a response timer value and a maximum retransmission number used for the radio link control.
