Step B. judges whether current scanning group simultaneous operation sequence number is consistent with feedback scan group simultaneous operation sequence number, and is being judged as under the consistent situation execution in step C;
Step C. scanning group data synchronous mark position is set to expression does not need synchronizing scanning group data (that is, to be set to vacation, FALSE), and to stop the scanning group timer, remove timer signal;
Step D. indicates according to the scanning group response message and carries out relevant treatment, and the notice interface display;
Step e. end operation.
On the other hand, if the scanning group synchro timer then before, terminal does not receive the scanning group syn ack message of system feedback, then restarts the scanning group synchro timer, resends the scanning group synchronous signaling.
As mentioned above, by technique scheme of the present invention, by scanning group data synchronous mark position and scanning group synchro timer are set, can be implemented in scanning group data changes, or during the system requirements synchronizing scanning group data, terminal is given system synchronously with scanning group data, has realized the consistency of the scanning group data of terminal and system.
