The time slot of signal, the CDMA Channel code of physical layer signal or user's scrambler of physical layer signal.
Wherein, the synchronizing signal is specifically as follows main synchronization（PSS）Signal, for example, for leading directly to (DMO, Direct
Mode Operation) call business, if system defines N number of PSS signals, DMO call business is divided into 0,1,2 ..., N-1
Individual priority a, PSS can indicate a priority.Such as 3 PSS sequence pairs answer 3 call business priority.3 grades most
Height, 1 grade minimum.The method that above-mentioned utilization synchronizing signal indicates the priority of individual calling/group-calling service, can support right of speech to rob
Account for, the mechanism such as preferential distribution of Radio Resource, be conducive to resource the whole network to dispatch.
Step 102, when calling terminal need initiate calling when, according to the thing of the service priority for indicating the calling
Layer resource is managed, it is determined that initiating the physical layer resources for calling and using, and corresponding calling is initiated.
In this step, the initiator for calling is calling terminal, it is necessary to using corresponding to the service priority of calling
Physical layer resources carry out initiation calling, so that terminal called physical layer resources according to used in the calling detected, it is determined that
