Embodiment
Fig. 1 is the flow chart of the group paging method embodiment one in the private network of the present invention, as shown in the figure, comprises the steps:
Step 110, the first priority parameters L is set according to the paging type of this group paging message in the base station after having detected the generation of group paging message.
In the present invention, the L value is more low, and priority is more high.For example, when described paging type is newly-built cluster group calling, the value of described L is set at L1 (as: L1=0); When described paging type is point when exhaling, the value of described L is set at L2 (as: L2=1); When described paging type when activating cluster group calling, the value of described L is set at L3 (as: L3=2); Wherein, L3＞L2＞L1.
In last example, the priority of newly-built cluster group calling is made as the highest reason is: when group just sets up, still do not have the terminal of monitoring and insert this group, wait for that the monitoring terminal that receives this newly-built cluster group calling can be a lot, therefore will preferentially satisfy the access demand that these monitor terminal; The priority that activates cluster group calling is made as minimum reason is: after group activates, still wait the quantity of the monitoring terminal of this group to be accessed usually can be not a lot, sometimes even do not have, therefore be not eager to send such group calling; Point is exhaled the beep-page message that refers at single monitoring terminal, though there is the monitoring terminal of waiting for that this point is exhaled, because negligible amounts, so its L value is set between being between the L value of above-mentioned two kinds of group callings.
Step 120, described base station obtains high-rise configuration information at described group paging message from core net, and sets the second priority parameters P according to this high level configuration information.
Wherein, described high-rise configuration information refers to the information that the user disposes for relevant group by core net when contracting.For example when certain group was designated as important group, the group paging message at this group should have higher priority so, at having different important groups, can be the corresponding different P value of group paging message sets.Wherein, the span of P value can preestablish, and for example is that 0～15, P value is more little, and priority is more high.
Step 130, described base station are weighted the queuing priority parameters R that obtains described group paging message after the read group total to described L and P.
For example, can calculate described R value according to equation one R=L*W1+P, wherein, W1 represents first weight parameter, definitely be higher than the queuing priority of a little exhaling and having activated cluster group calling for the queuing priority that guarantees newly-built cluster group calling, then can make W1 greater than the higher limit of described P, for example W1＞15.
Step 140, described base station sends a plurality of described group paging message successively according to described R value in a paging cycle.
Particularly, be to send successively according to R value order from low to high.After carrying out this step, a kind of possible result is that all group paging message to be sent all is carried out successfully transmission in described paging cycle, in this case, the group paging message that the group paging message that the R value is low is high prior to the R value is sent out, therefore be conducive to satisfy the transmission demand of the high group paging message of priority, to reduce the paging time delay; Another kind of possible result is because the quantity of the group paging message that will send in this paging cycle has surpassed maximum group paging number, make part part group beep-page message to be sent out, in this case, the group paging message that is successfully sent all is the message that the R value is lower, priority is higher, therefore also is conducive to reduce the paging time delay.
In addition, when a plurality of group paging message have identical R value, be message at the same level with described a plurality of group paging Message Records; Set the 3rd priority parameters T of each group paging message respectively according to the generation time of each group paging message in the described message at the same level; Send each group paging message in the described message at the same level successively according to described T value, so that generation time group paging message more early is sent out more earlier.That is to say that when the R value was identical, the preferential group paging message that generates earlier that sends was to reduce the paging time delay as far as possible.
The described method of present embodiment is that group paging message to be sent determines that priority is with the transmission of ranking by taking all factors into consideration this two aspects factor of paging type and high-rise configuration information, thereby can more reasonably dispose the queuing priority of group paging message, to reduce the paging time delay.
Fig. 2 is the flow chart of the group paging method embodiment two in the private network of the present invention.Once after being determined, no matter whether corresponding group paging message is successfully sent, this R value all can not change, so embodiment one described method belongs to static queueing form in the queuing priority parameters R described in the said method embodiment one.And present embodiment two provides a kind of R value variable dynamic queueing form, as shown in Figure 2, comprises the steps:
Wherein, the explanation of relevant L value can be referring to the related content of said method embodiment one.
Wherein, the explanation of relevant P value can be referring to the related content of said method embodiment one.
Wherein, the span of M value can preestablish, and for example is that 0～31, M value is more little, and priority is more high.Particularly, if consider the paging type, then when dynamically lining up, set point exhales M value with newly-built cluster group calling less than the M value that activates cluster group calling.For example, exhale or newly-built cluster group calling at point, the initial value of M can be set at 15, up to being kept to till 0; At activating cluster group calling, the initial value of M can be set at 31, up to being kept to till 16.Exhale or the priority of newly-built cluster group calling is higher than the priority that has activated cluster group calling all the time with guarantee point.
Particularly, can calculate described R value according to equation two: R=M*W1*W2+L*W1+P.Wherein, W2 represents second weight parameter, for the queuing priority that guarantees newly-built cluster group calling definitely is higher than the queuing priority of a little exhaling and having activated cluster group calling, then can make W1 greater than the higher limit of described P, and make W2 greater than the higher limit of described L W1＞15 for example, W2＞2.
Particularly, can send successively according to R value order from low to high.Similar with said method embodiment one, if there is message at the same level, then can set the 3rd priority parameters T of each group paging message according to the generation time of each group paging message in the message at the same level respectively; And send each group paging message in the described message at the same level successively according to described T value, so that generation time group paging message more early is sent out more earlier, particularly, can send successively according to T value order from low to high, so that generation time group paging message more early is sent out more earlier.That is to say that when the R value was identical, the preferential group paging message that generates earlier that sends was to reduce the paging time delay as far as possible.
Wherein, because the M value is more little, priority is more high, and the purpose that therefore reduces the M value is in order to improve the priority of this group paging message, to promote that this group paging message is sent as early as possible.For example, the each transmission failed, and the M value can be subtracted one.
Particularly, can send successively according to R value order from low to high.Wherein, the interior group paging message of failing and being postponed transmission that sends of the paging cycle before a plurality of group paging message described in this step both can be included in also can comprise the group paging message that plan originally sends in current paging cycle.These group paging message are all unified queuing according to the R value of self.
If a group paging message all sends failure in continuous two paging cycle, then can continue to reduce the M value of this group paging message, it is ranked in next paging cycle with higher priority, thereby improve the possibility that it is successfully sent.
The described method of present embodiment is by taking all factors into consideration paging type, high-rise configuration information and waiting for that this three aspect factor of duration is that group paging message to be sent determines that priority is with the transmission of ranking, thereby can more reasonably dispose the queuing priority of group paging message, to reduce the paging time delay.
