Direct mode mobile telephony system

摘要

The method involves determining a broadcasting time corresponding to a start time of a synchronization slot. A synchronization information is transmitted during the synchronization slot after determining the broadcasting time, when the broadcasting time expires. The reception of the synchronization information emitted by a mobile station during the synchronization slot is detected after determining the broadcasting time, when the broadcasting time does not expire. A access collision is detected, when receiving the information during the slot. An independent claim is also included for a computer program comprising a set of instructions for performing a access collision managing method.
