Patent ID: 8306545

Claim:
A method for reassigning traffic channel configuration, applicable to reassigning traffic channel configuration between a site A and a site B with the reassignment being initiated by the site A, comprising steps of: transmitting, by the site A, a reassignment message containing reassigned traffic channel configuration to the site B; determining, by the site B, whether the site B correctly receives the reassignment message, processing traffic data according to a determining result and transmitting the traffic data processed to the site A; processing, by the site A, the traffic data received, and determining whether the site B correctly receives the reassignment message through determining whether the traffic data are correct; establishing, by the site A and the site B, communications with each other utilizing first traffic channel configuration, wherein a sate sequence number of the site A, SA, is the same as a state sequence number of the site B, SB; performing, by the site A and the site B, channel coding on respective messages to be transmitted to each other to generate encoded messages, each encoded message including a message part and a code part; mapping, by the site A and the site B, respective encoded messages utilizing functions of YA(SA) and YB(SB), and transmitting the mapped messages to each other, wherein the YA(SA) is a function of the SA and the YB(SB) is a function of the SB, and the YA(SA) and the YB(SB) are invertible mapping known by the site A and the site B; and performing, by the site A and the site B through utilizing functions of YA −1 (SA) and YB −1 (SB), inverse mapping on mapped messages received respectively, and then performing channel decoding on respective results of the inverse mapping; wherein the step of transmitting by the site A the reassignment message to the site B comprises: transmitting, by the site A to the site B through utilizing the first traffic channel configuration, the reassignment message which contains the reassigned traffic channel configuration for communication with the site B and which is processed through the channel coding and the mapping.
