Abstract

The invention provides a switching method based on combination priority. The switching method based on the combination priority comprises the steps that firstly, when a calling request arrives, whether an idle channel exists or not is judged, if the idle channel exists, channel allocation is directly performed on a requested calling, and otherwise, the second step is executed; secondly, the combination priority P of the requested calling is calculated; thirdly, the combination priority P of the requested calling is obtained through calculation and is switched. The switching method performs switching of different types by setting the combination priority and according to the combination priority, well guarantees communication quality with high priority, and improves the use efficiency of channels.

Description

A kind of changing method based on combination priority level

Technical field

The present invention relates to channel and seize switching field, particularly a kind of changing method based on combination priority level.

Background technology

Going offline of causing in handoff procedure often cannot be initiated more to make us accepting than new calling, switches so reduce the large center of gravity that drop rate (PH) is design changing method.Resource reservation schemes more can access chance for switching user provides, but also considerably increases the blocking probability newly made a call simultaneously.In the networking mode of great Qu, for service switchover channel reservation resource means the increase of the risk of the wasting of resources, do not meet the requirement of group system high channel utilance, so resource reservation schemes being not suitable for.

Summary of the invention

In view of this, the invention provides a kind of changing method based on combination priority level, combination priority level is set according to call property, thus switch based on combination priority level, improve the utilance of channel, meet the calling of different attribute to the different requirements switching drop rate.

The invention provides a kind of changing method based on combination priority level, comprising:

Step 1: 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 2;

Step 2: the combination priority level P calculating the calling of described request;

Step 3: the combination priority level P based on the calling of the described request calculated switches.

Described step 3 comprises:

Step 3.1: judge that whether the combination priority level P of the 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, enter step 3.2 if exist, enter step 3.4 if do not exist; If be no more than the first set point, then enter step 3.3;

Step 3.2: 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 3.3: judge that whether the combination priority level P of the 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 3.4;

Step 3.4: judge whether waiting list is less than preseting length, if be less than preseting length, then enter step 3.5; Otherwise the calling rejected said request, does not add waiting list;

Step 3.5: the calling of described request is 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 priority.

In sum, the changing method based on combination priority level of 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.

Embodiment

For making the object of the embodiment of the present invention, technical scheme and advantage clearly, clear, complete description is carried out below by the technical scheme in the embodiment of the present invention, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of protection of the invention.

The invention provides a kind of changing method based on combination priority level, comprising:

Step 1: 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 2;

Step 2: the combination priority level P calculating the calling of described request;

Step 3: the combination priority level P based on the calling of the described request calculated switches.

Described step 3 comprises:

Step 3.1: judge that whether the combination priority level P of the 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, enter step 3.2 if exist, enter step 3.4 if do not exist; If be no more than the first set point, then enter step 3.3;

Step 3.2: 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 3.3: judge that whether the combination priority level P of the 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 3.4;

Step 3.4: judge whether waiting list is less than preseting length, if be less than preseting length, then enter step 3.5; Otherwise the calling rejected said request, does not add waiting list;

Step 3.5: the calling of described request is 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 priority.

1) type of call

Call request to be processed need be divided into and newly to make a call and switch call two class, differentiated treatment is carried out 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.

2) User Priority

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.

3) role is called out

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.

Last it is noted that above embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in previous embodiment, or equivalent replacement is carried out to wherein portion of techniques feature, and these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
