Brief description of the drawings
Fig. 1 is the schematic flow sheet of the embodiment of the present invention one.
Embodiment
For making the object, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.
Core concept of the present invention is: the corresponding relation of physical layer signal and service priority while setting in advance calling, like this, can utilize the priority of physical layer signal indicating call business, thereby can in the time of wireless link, trigger and carry out distributing rationally of Radio Resource according to service priority information.
Fig. 1 is the schematic flow sheet of the embodiment of the present invention one, and as shown in Figure 1, this embodiment mainly comprises:
Step 101, the pre-configured physical layer resources that is used to indicate each service priority.
Be used in this step, the precedence information of group service and physical layer resources can be set up to corresponding relation, so that can be in physical layer synchronization early stage, just can make terminal determine the priority of calling, and then realize the calling access procedure based on priority, to reach the object of the priority mechanism of supporting expeditiously trunked call.
In actual applications, in system, the division of service priority can be determined according to actual needs, does not repeat them here.
Preferably, the above-mentioned physical layer resources that is used to indicate each service priority is specifically as follows:
The subframe of the phase place of synchronizing signal, physical layer signal, the Resource Block of physical layer signal, physical layer signal, the time slot of physical layer signal, the CDMA Channel code of physical layer signal or user's scrambler of physical layer signal.
Wherein, described synchronizing signal is specifically as follows main synchronous (PSS) signal, for example, and for straight-through (DMO, Direct Mode Operation) call business, if system definition N PSS signal, DMO call business is divided into 0,1,2,, N-1 priority, a PSS can indicate a priority.For example 3 corresponding 3 call business priority of PSS sequence.3 grades the highest, and 1 grade minimum.The method of the above-mentioned priority of utilizing synchronizing signal instruction individual calling/group-calling service, can support right of speech to seize, and the mechanism such as the priority allocation of Radio Resource are conducive to the scheduling of resource the whole network.
Step 102, in the time that calling terminal need to make a call, according to the physical layer resources of service priority that is used to indicate described calling, determine and initiate the physical layer resources that described calling is used, and initiate corresponding calling.
In this step, be calling terminal for the initiator who calls out, need to utilize the corresponding physical layer resources of service priority of calling out to make a call, so that the physical layer resources that terminal called uses according to the calling detecting, determine the service priority of calling, thereby can realize the early stage instruction to service priority in physical layer synchronization.
Step 103, in the time that terminal called detects described calling, the indicated service priority of physical layer resources using according to described calling, determine the order of the terminal access procedure of the described calling of current triggering, and trigger described calling terminal according to described order and carry out described terminal access procedure.
In this step, terminal called can same existing system to calling out the concrete grammar detecting.Here, the physical layer resources that terminal called can directly be used according to calling is determined the service priority of calling, because terminal in actual applications may detect multiple callings simultaneously, now terminal can be according to the service priority of calling out, determine the current order for this calling initiating terminal access procedure, thereby can reach the object of the priority mechanism of supporting trunked call.
Step 104, described calling terminal are carried out described terminal access procedure, wherein, according to described service priority, are described call distribution Radio Resource, and set up corresponding wireless link.
In this step, calling terminal can be carried out the terminal access procedure based on service priority according to call business priority, in this process, be described call distribution Radio Resource according to service priority, and set up corresponding wireless link, thereby can reach the object of the priority mechanism of supporting trunked call.
Further, the physical signalling scope that can also utilize physical layer resources to limit terminal called to carry out monitored call, terminal only need be monitored part physical resource, that is to say, only need to monitor part call number space, and do not need all call number spaces to monitor, thereby can improve the treatment effeciency of terminal, the power consumption of minimizing terminal, the stand-by time of prolongation terminal.Concrete, can adopt following method to realize this purpose:
First, the pre-configured physical layer resources that is used to indicate each type of call.
Adopt this step, can utilize physical layer resources to carry out indicating call type, like this, due to the corresponding a part of physical layer resources of every kind of type of call, so, terminal can be monitored in a corresponding physical layer resources of type of call of supporting at oneself, thereby can effectively reduce the call number spatial dimension of monitored call.
The same existing system of division of concrete type of call, for example: can comprise: speech business, (short/large) data service, emergence call service, system control information (endpoint registration procedural information), singly cry, group calling etc.
Preferably, the above-mentioned physical layer resources that is used to indicate each type of call is specifically as follows:
The subframe of the phase place of synchronizing signal, physical layer signal, the Resource Block of physical layer signal, physical layer signal, the time slot of physical layer signal, the CDMA Channel code of physical layer signal or user's scrambler of physical layer signal.。
For example, can utilize auxiliary synchronous (SSS) signal in synchronizing signal to carry out indicating call type, different SSS indicates different type of calls.
Then, in step 102 in the time that calling terminal need to make a call, according to be used to indicate described calling service priority physical layer resources and be used to indicate the physical layer resources of type of call of described calling, determine and initiate the physical layer resources that described calling is used.
Here, in the time making a call, need the physical layer resources of considering the type of call that is used to indicate described calling to initiate, with the type of service under indicating call, limit call number spatial dimension.For example, when the pre-configured PSS of utilization signal designation service priority, while utilizing SSS signal designation type of call, can utilize and call out the initiation that corresponding a pair of PSS/SSS sequence is called out.
Correspondingly, in step 103, terminal called can be only within the scope of physical layer resources corresponding to signing type of call, the detection of calling out, i.e. and the concrete grammar of described detection can be:
Described terminal called carries out calling detection within the scope of the physical layer resources that is used to indicate its signing type of call.
In order to improve reliability and the fail safe of service call, can be after setting up wireless link, further introduce the authentication process of application layer, described calling is carried out to wireless link authentication, institute's described certification of fruit is passed through, the calling terminal of described calling and terminal called enter service call state, otherwise, stop described call business.
In sum, these are only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
