Embodiment
For making object of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein only for explaining the present invention, being not intended to limit the present invention.
Refer to Fig. 1, Fig. 1 is the flow chart of the changing method preferred embodiment based on combination priority level of the present invention.As shown in Figure 1, the described changing method based on combination priority level, comprises the following steps:
Step S100, when call request reaches, judge whether to there is idle channel; If there is idle signal, then channel allocation is carried out in the direct calling to request; Otherwise, enter step B;
The combination priority level P of the calling of step S200, calculating described request;

Embodiment further, in the described changing method based on combination priority level, described step S300 comprises:
Step S301, judge that whether the combination priority level P of calling of described request is more than the first set point, if more than the first set point, then judge whether to exist in the calling of serving the calling that combination priority level P is less than the first set point, if exist and enter step S302, enter step S304 if do not exist; If be no more than the first set point, then enter step S303;
Step S302, the calling that search combination priority is minimum in the calling of serving, then the minimum calling of described combination priority level is made to abdicate shared channel, and the calling of order request enters waiting list, and rank in waiting list according to combination priority level, wait for channel allocation;
Step S303, judge that whether the combination priority level P of calling of described request is more than the second set point, if be no more than the second set point, then the calling rejected said request, does not add waiting list; If more than the second set point, then enter step S304;
Step S304, judge whether waiting list is less than preseting length, if be less than preseting length, then enter step S305; Otherwise the calling rejected said request, does not add waiting list;
Step S305, the calling of described request to be added in described waiting list, and rank in waiting list according to combination priority level, wait for channel allocation; Wherein, described combination priority level P=p1+p2+p3, p1 are type of call priority; P2 is User Priority; P3 is calling role top grade.
Wherein, type of call call request to be processed need be divided into and newly to make a call and switch call two class, carries out differentiated treatment to it.New call request unsuccessfully means cannot initiate new calling, and handover call request failure then means ongoing dropped calls, so arrange the priority of priority higher than new calling of switch call.
Except in system to different user setting priority except, calling itself also can carry precedence information, such as urgent call (limit priority) etc.Digital clustering communication system requires to take to different priorities calling the treatment measures that match, and as urgent call must obtain response at once, ordinary call can add temporary suspension etc. because of high-priority call.No matter be User Priority or the call priority of setting, be all changeless when call request arrives.The priority that this two class is determined by user can be merged, be referred to as User Priority.
The role of calling, mainly for group calling, in a road group calling, always only has an initiator (callowner) and multiple participant (call participator), only has initiator to have the right terminated call.In trunked communication system, group calling often accounts for more than 80% of business, and the user initiating group calling is obviously different on the impact of this road group calling with the user participating in group calling: if the initiator of positive group calling goes offline, whole end of calling, full group user can experience calling and be interrupted; And for the participant of group calling, going offline only affects unique user, and group call still can normally carry out.So the priority of the master side of exhaling of setting group calling is higher than the priority of participant.
The value (value of p1, p2, p3) of concrete priority can be arranged according to actual needs.
Visible, the present invention by arranging combination priority level, and carries out the switching of different modes according to combination priority level, the speech quality of high priority is well ensured, improves the service efficiency of channel.
