(57) [Summary] [Problem] During communication, Timer_POLL (timer) or Max-PD (one of SSCOP parameters) Can be changed, thereby performing dynamic high-efficiency data transfer according to the processing capacity of the receiving device. SOLUTION: Timer_POLL expiration processing section 100 In ITU-T Recommendation Q. In 2110, Timer_ If a POLL-PDU is sent due to POLL expiration, The transmission factor is stored in the factor storage processing unit 102a. S When the D-transmission processing unit 101 transmits an SD-PDU, When a POLL-PDU is transmitted due to a PD or a transmission-side credit, the transmission factor is stored in the factor storage processing unit 102b. To memorize. STAT-PDU reception processing section 106 sets ST When the AT-PDU is received, Timer_POLL • Max -Change the value of Timer_POLL in the PD change processing unit 107. |
