Abstract
The invention discloses a resource distribution method of an emergency call, comprising following steps: A, a base station reserves a certain amount of channel resource, wherein the channel resource reserved by the base station is only used for being distributed to the emergency call; B, after receiving a connect message of the emergency call, the base station judges whether the current rest channel resource is more than the reserved channel resource or not, wherein if the current rest channel resource is more than the reserved channel resource, the channel resource is distributed to the emergency call; if not, continuously judging whether the reserved channel resource is zero or not, and if not, the channel resource is distributed to the emergency call; if the reserved channel resource is zero, traversing the occupation situation of the current channel resource, searching for a call according to predetermined rules, releasing the call, and distributing the channel resource for the emergency call. Applying the invention can realize that the emergency call can be also established even when the channel resource of the system is insufficient so as to distribute the channel resource to the emergency call without waiting for dismantling another call, thereby reducing establishing time of the emergency call.
Description
Technical field:
The present invention has realized a kind of at wireless communication system, especially realizes the resource allocation methods of urgent call in the trunked communication system.
Background technology:
Group system is being brought into play increasing effect with its strong functions in dispatch control.Urgent call is a critical function in the group system, and it is defined as presses emergency call key, and system provides service rapidly, is the calling of highest level, even the system channel resource deficiency will guarantee that also urgent call can insert.
General, the resource race to control implementation method of urgent call as shown in Figure 1, after the connection message of network side is received in the base station, if system channel resource abundance then directly give the urgent call Resources allocation, if system channel resource deficiency, find out a calling earlier and discharge, wait then this call out has discharged after, again to the urgent call Resources allocation.
Yet the shortcoming of doing like this is to make urgent call when system resource is not enough, wait another to call out and could give the urgent call Resources allocation after elder generation has discharged, and access speed can slow down a lot.
Summary of the invention:
The technical problem to be solved in the present invention is, a kind of resource allocation methods of urgent call is provided, and guaranteed that urgent call also can insert fast when system resource is not enough.
In view of above technical problem, the resource allocation methods of a kind of urgent call that the present invention proposes may further comprise the steps:
The channel resource of some is reserved in A, base station, and the channel resource that described base station is reserved only is used to distribute to urgent call;
After the connection message of urgent call was received in B, described base station, whether the channel resource of judging current residual was greater than the channel resource of described reservation, if give described urgent call allocation of channel resources may; If not, continue then to judge whether the channel resource of described reservation is zero, if not, described urgent call allocation of channel resources may given; If, travel through the situation that takies of current channel resource, find out a calling according to pre-defined rule, after it is discharged, give described urgent call allocation of channel resources may.
Further, non-vanishing when the channel resource of judging described reservation, to after the described urgent call allocation of channel resources may, travel through the situation that takies of current channel resource, search a calling according to described pre-defined rule, with its release.
Further, described resource allocation methods is used for group system.
Further, described channel resource comprises WALSHCODE, frame biasing, forward power, CE (Channel Element, Channel Elements) resource.
Further, described channel resource is the CE resource.
Further, described pre-defined rule is provided with according to call priority weights and the preferential dismounting indication of preemption, wherein, described call priority weights, a calling has only call priority weights, and described call priority weights are more little, and its class of call is high more.
Use the present invention, can realize that urgent call is when system channel resource is not enough, also can set up, compare with prior art, owing to adopted the method for reserved resource, make need not wait has removed another and has called out after, just to the urgent call Resources allocation, so reduced settling time of urgent call.
Description of drawings:
Fig. 1 is a urgent call resource allocation methods of the prior art;
Fig. 2 is the urgent call resource allocation methods of the embodiment of the invention.
Embodiment:
Core concept of the present invention is, guarantees the resource allocation of urgent call by the channel reservation resource, and then realizes the quick access of urgent call.And when system resource was not enough, the Ergodic Theory resource discharged a certain calling by pre-defined rule, guaranteed the access of urgent call.
Be that example further specifies the inventive method with professional group system below based on CDMA2000.In group system, a channel resource generally includes WALSHCODE, frame biasing, forward power, CE resource or the like, but general, and the critical bottleneck resource is the CE resource.Therefore we are example with the group system below, the flow chart of CE resource allocation methods when describing urgent call of the present invention, and the disposition of other resources is in like manner.As shown in Figure 2, may further comprise the steps:
The first step, base station keep ReserveChannelNum CE usually, only are used for urgent call, and non-emergency call can not be distributed these resources, and (ReserveChannelNum is an integer, and it is configurable to make the backstage, is synchronized to the base station after can revising at any time.If do not need emergency call function like this, can be configured as 0, reserved resource does not guarantee not have the wasting of resources, it is fixed that concrete number can rule of thumb be worth);
Second step, base station are behind the connection message of the urgent call of receiving network side, and whether the idle CE number of judging current residual greater than ReserveChannelNum, if greater than, to the urgent call Resources allocation; If be less than or equal to, the flow process below continuing;
The 3rd step, judge whether the idle CE number of current residual equals 0, if equal 0, then earlier traversal CE takies situation, finds out a calling according to predetermined rule and discharges, wait discharged after, then to the urgent call Resources allocation; If be not equal to 0, then give the urgent call Resources allocation earlier, travel through CE then and take situation, find out a calling according to predetermined rule and discharge.
Introduce predetermined rule below and how to set, introduce two notions in the group system earlier:
Call priority weights Call Priority Value (being called for short CPV): call priority is exactly in order to satisfy the different demands with different resource occupation abilities of calling out.Call priority weights (CPV) unified Definition, CPV and calling are associated, and a calling has a CPV value, and the CPV of calling can directly compare.CPV numerical value is more little, illustrates that priority is high more.
The preferential indication Pre Emptive Indicator (being called for short PEI) that removes of preemption: when system resource is not enough, need decides according to the dismounting indication field that network side hands down and remove which kind of service-user for urgent call.If the common network cluster, so system except cluster service is provided, also might provide speech business and data service.Therefore introduce the PEI notion, PEI has stipulated the dismounting order of miscellaneous service.
The value meaning of PEI is as follows:
0x00: can only tear cluster open
0x01: data＞cluster (tear cluster earlier open, tear data again open)
0x02: voice＞data＞cluster (tearing cluster earlier open, then data, voice at last)
0x03: cluster＞data (tear data earlier open, tear cluster again open, can not tear voice open)
0x04: voice＞cluster＞data (tearing data earlier open, then cluster, voice at last)
0x05: cluster＞voice＞data (tearing data earlier open, then voice, cluster at last)
Other: keep
With PEI=2 is example, illustrates how to choose the principle that is removed calling.PEI=2 tears voice earlier open, tears data then open, tears cluster again open.Therefore in the above-described embodiments,, at first travel through the speech business occupation condition of base station, select the maximum conduct dismounting object of a CPV value then when remaining channel resource during less than reserved resource; If there is not the voice user, then travel through the situation of the data service resource occupation of base station, select the maximum conduct of a CPV value to remove object then; If there is not the data user, then travel through the group service of base station, select the maximum conduct of a CPV value to remove object.
The above is embodiments of the invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within the claim scope of the present invention.
