Description
Technical field
The present invention relates to the group calling technology in the group system, particularly a kind of assigning method of group call resource.
Background technology
Based on Global Link mobile communcations system (GSM, Globe System of MobileCommunication) group system is to realize the system of professional clustering functionality on the GSM platform, except all general servicies of GSM network can be provided, can also provide professional group service, such as GT800 (GSM TRUNK 800M).
The network configuration of GT800 as shown in Figure 1, comprise: with the essentially identical base transceiver station (BTS of GSM, Base Transceiver Station), base station controller (BSC, Base StationController), (MSC of mobile switching centre, Mobile Switching Centre), attaching position register (HLR,) wait a series of network element devices, in addition, GT800 has increased Group Call Register (GCR) equipment on MSC.GCR is mainly used in storaged voice group-calling service (VGCS)/Voice Broadcast Service (VBS) group data, as: the cell list of VGCS/VBS base group attribute, group call region, dispatcher's tabulation, RelayMSC tabulation etc.
GT800 has preserved the VGCS/VBS tabulation that the user contracts at HLR, and when user position update success back or initiation point to point call, HLR copies signatory Groups List in the data of self storing to VLR Visitor Location Register (VLR).Wherein, the distinctive points of the VGCS/VBS data of storing among HLR and the GCR is: HLR only preserves user's which group of having contracted; The base attribute of only preservation group of GCR, not user list information in the group.
In the practical application, GCR can be positioned at MSC as shown in Figure 1, also can be independent of outside the MSC to exist.
The assignment mode that multiple group call resource is arranged in the prior art, such as: assignment, delay assignment etc. immediately.Wherein, assignment immediately is meant: when group calling is initiated, and the A interface circuit and the Traffic Channel (TCH) of all sub-districts in the assignment group call region immediately; Delay assignment can be delay assignment A interface circuit or delay assignment TCH.
Described delay assignment A interface circuit is meant: when group calling is initiated, and A interface circuit and not assignments of TCH, BSC enables descending detection, when only the user of this group being arranged under detecting certain sub-district, ability assignment A interface circuit and TCH.Described delay assignment TCH is meant: when group calling is initiated, and assignment A interface circuit, but the TCH of not assignment group call cell, BSC enables descending detection, when only the user of this group being arranged under detecting certain sub-district, ability assignment TCH.
The shortcoming of prior art is:
If adopt assignment immediately, even some sub-district does not have the user, also can cause the waste of resource, and when the concurrent peak of group calling, may cause the not enough and link congestion of A interface circuit for this sub-district assignment A interface circuit and TCH.If the employing delay assignment, though can save resource according to user's concrete distribution Resources allocation, because the time that needs BSC to carry out descending detection, so the speed that group calling is set up is slow.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of assigning method of group call resource, when carrying out the group call resource assignment, can take into account the consideration group calling and set up speed and resource utilization.
Technical scheme of the present invention is achieved in that
A kind of assigning method of group call resource, the method includes the steps of:
When A, group calling initiate, determine the focus value of sub-district, and determine Hot Spot and non-Hot Spot according to sub-district focus value according to the movable frequent situation of community user;
B, to Hot Spot assigned resources immediately, to non-Hot Spot delay assignment resource.
Describedly determine that according to the movable frequent situation of community user the method for focus value is:
When A3, group calling release, judge that this sub-district has or not the group-calling service user, if there is the group-calling service user this sub-district, then the focus value increases; If this sub-district does not have the group-calling service user, then the focus value reduces.
Further comprise before the steps A: the maximum and the minimum value that set in advance the focus value;
In the steps A 3, when group calling discharges, if be defined as this sub-district the group-calling service user is arranged, and be defined as this sub-district focus value and reached maximum, then the focus value does not increase; When group calling discharges, do not have the group-calling service user if be defined as this sub-district, and be defined as this sub-district focus value and reached minimum value, then the focus value does not reduce.
Further comprise before the steps A: the focus critical value is set;
The described focus value according to the sub-district of steps A determines that the method for Hot Spot and non-Hot Spot is: if the focus value of group call cell, determines then that this group call cell is a Hot Spot greater than the focus critical value; If the focus value of group call cell, determines then that this group call cell is non-Hot Spot less than the focus critical value.
Further comprise before the steps A: the focus critical value is set, and two focus values corresponding constant Hot Spot of difference and the constant non-Hot Spot that is different from the focus critical value is set;
The described focus value according to the sub-district of steps A determines that the method for Hot Spot and non-Hot Spot is: if the focus value of group call cell greater than the focus critical value, and is different from the focus value of corresponding constant non-Hot Spot, determine that then this group call cell is a Hot Spot; If the focus value of group call cell is less than the focus critical value, and be different from the focus value of corresponding constant Hot Spot, determine that then this group call cell is non-Hot Spot; If the corresponding constant Hot Spot of the focus value of group call cell determines that then this group call cell is constant Hot Spot, belongs to Hot Spot; If the corresponding constant non-Hot Spot of the focus value of group call cell determines that then this group call cell is constant non-Hot Spot, belongs to non-Hot Spot.
If the focus value of sub-district equals the focus critical value, determine that then this group call cell is Hot Spot or non-Hot Spot.
Further comprise before the steps A: the initial value that group call cell focus value is set is the focus critical value.
Further comprise before the steps A: the configuration group call mode; When group calling is initiated, determine that group call mode is the dynamic assignment resources mode after, execution in step A.
Described group call mode is: but dynamic assignment resources mode or assigned resources and resource release mode or assigned resources and resource can not release mode or delay assignment A interface circuit pattern or delay assignment Traffic Channel TCH patterns immediately immediately.
The method of described assignment immediately is: immediately this resource of assigned resources and assignment for can discharge or immediately assigned resources and this resource of assignment for discharging.
The method of described delay assignment is: delay assignment A interface circuit or delay assignment TCH.
When the present invention is the group calling initiation, according to the focus situation dynamic assignment group call resource of group call cell.
The present invention has following beneficial effect:
1) the present invention can carry out the group calling assignment according to the motion frequency of community user, can adopt assignment immediately for the sub-district that User Activity is frequent relatively, can adopt delay assignment in not frequent sub-district relatively for User Activity, therefore in the time of can overcoming in the prior art assignment immediately, even some sub-district does not have the user, also can be this sub-district assignment A interface circuit and TCH, cause the wasting of resources, or during delay assignment, set up the also slow problem of speed for the sub-district group calling that the user is arranged, and then solved the contradiction that speed and resource utilization are set up in group calling.
2) the present invention carries out assignment immediately for Hot Spot, can guarantee the speed of setting up of hot spot region group calling, carries out delay assignment for non-Hot Spot, can save the Internet resources of non-hot spot region.
3) among the present invention, network side can be discerned the hot spot region automatically according to the focus value, and moves with travel frequency according to user's position and to adjust the hot spot region automatically, therefore dynamic assignment group call resource according to actual needs, both saved resource, guaranteed also that speed was set up in the group calling of hot spot region.

Embodiment
The core concept of group call resource distribution method is among the present invention: when group calling is initiated, determine Hot Spot and non-Hot Spot according to the frequent situation of the User Activity of sub-district; To Hot Spot assigned resources immediately, to non-Hot Spot delay assignment resource.
The frequent situation of the User Activity of described sub-district focus value representation, described focus value can be when storing the group calling data in MSC, to increase a focus value attribute in advance in each sub-district of group call region.The focus value is just effective when group calling is configured to the dynamic assignment resource usually.The initial value of group call cell focus value is configurable, and when group calling discharged, if there is the group-calling service user this sub-district, then the focus value can increase, if this sub-district does not have the group-calling service user, then the focus value can reduce.The focus value can be provided with maximum and minimum value usually, and the focus value reaches maximum, then no longer increases, and reaches minimum value, then no longer reduces.
When determining Hot Spot and non-Hot Spot according to the frequent situation of the User Activity of sub-district, generally undertaken by comparative heat point value and focus critical value, described focus critical value is the parameter that network side sets in advance, here, if the focus value of sub-district is greater than the focus critical value, think that then this community user activity is frequent relatively, and can determine that this group call cell is a Hot Spot, if the focus value of sub-district is less than the focus critical value, think that then this community user activity is not frequent relatively, and can determine that this group call cell is non-Hot Spot.If the focus value of sub-district equals the focus critical value, then can determine that according to being provided with in advance this group call cell is Hot Spot or non-Hot Spot, generally, when the focus value of sub-district equals the focus critical value, determine that this sub-district is a Hot Spot.The initial value of focus value is set to the focus critical value usually.
In the group call cell, also can be assignment immediately or delay assignment for some sub-district manual configuration, manual configuration can be referred to as constant Hot Spot for the sub-district of assignment immediately, and manual configuration is that the sub-district of delay assignment can be referred to as constant non-Hot Spot.Described constant Hot Spot, constant non-Hot Spot are that MSC is pre-configured according to customer requirements etc.If can have constant Hot Spot or constant non-Hot Spot in the group call cell, then can specify two specific focus values corresponding constant Hot Spot of difference and constant non-Hot Spot that are different from the focus critical value in advance, and when judging the focus situation of group call cell, if the focus value of sub-district is greater than the focus critical value, and be different from the focus value of corresponding constant non-Hot Spot, can determine that then this group call cell is a Hot Spot; If the focus value of sub-district is less than the focus critical value, and be different from the focus value of corresponding constant Hot Spot, can determine that then this group call cell is non-Hot Spot; If the corresponding constant Hot Spot of the focus value of sub-district can determine that then this group call cell is constant Hot Spot; If the corresponding constant non-Hot Spot of the focus value of sub-district can determine that then this group call cell is constant non-Hot Spot.Constant Hot Spot belongs to Hot Spot, and constant non-Hot Spot belongs to non-Hot Spot.
For constant Hot Spot and constant non-Hot Spot, its focus value is specific value, and no matter whether this sub-district has the group-calling service user when group calling discharges, does not all carry out the increase or the minimizing of focus value.
When specific implementation is of the present invention, can pre-configured group call mode, such as being configured to: dynamic assignment resource, assigned resources and resource can discharge, assigned resources and resource can not discharge, delay assignment A interface circuit, delay assignment TCH etc. immediately immediately.Wherein, MSC can be when definite group call mode be the dynamic assignment resource, and just according to the focus situation dynamic assignment group call resource of group call cell, MSC does not carry out the dynamic assignment process under all the other group call modes.
Whether described dynamic assignment resource is meant: when group calling is set up, be Hot Spot according to the sub-district, determine that assigned resources still is the delay assignment resource immediately.
Described assigned resources immediately and resource can discharge and be meant: this resource of assigned resources and assignment is for discharging immediately, be that group calling is when setting up, assignment A interface circuit and TCH channel immediately, and if detect the group call cell no user in the group-calling process, the TCH channel of respective cell discharged automatically.
Described assigned resources immediately and resource can not discharge and be meant: this resource of assigned resources and assignment be for discharging immediately, when promptly group calling is set up, and assignment A interface circuit and TCH channel immediately, and do not discharge resource in the group-calling process.
Following with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.
Fig. 2 is in the embodiment of the invention, and according to the process schematic diagram of sub-district focus situation assignment group call resource, this process comprises:
Step 201: when group calling was initiated, MSC judged whether group call cell is Hot Spot, if then execution in step 202, otherwise execution in step 203.
In the step 201, when group calling was initiated, MSC judges whether group call cell is that Hot Spot can further comprise before: it was the dynamic assignment resource that MSC is defined as group call mode.
Here,, can carry out according to existing scheme if MSC is defined as group call mode when not being the dynamic assignment resource, such as: assignment or delay assignment etc. immediately.
Described dynamic assignment resource is the pre-configured group call mode of MSC, except the dynamic assignment resource, MSC can also support immediately assigned resources and resource can discharge, group call mode such as assigned resources and resource can not discharge, delay assignment A interface circuit, delay assignment TCH immediately.All group call modes can be in MSC or GCR configuration, and the method for concrete configuration can be with reference to the method that is configured to assignment immediately or delay assignment in the prior art.
When MSC can support the assignment mode of dynamic assignment resource, MSC or GCR can increase a focus value attribute in each sub-district of group call region in advance, specifically: MSC or GCR increase a focus value attribute in each sub-district of group call region, the initial value C of focus value is generally the focus critical value, maximum Cmax when the focus value also can be provided with dynamic change and minimum value Cmin.The scope of initial value, maximum Cmax, minimum value can be provided with arbitrarily, such as: be set to 1～0x7D etc., and initial value C is between minimum value Cmin and maximum Cmax, such as: initial value C be 10, maximum Cmax is 30, minimum value Cmin is 1 etc.During practical application, the value of described initial value C, maximum Cmax, minimum value Cmin can be adjusted according to the network actual conditions.
MSC or GCR can be constant Hot Spot or constant non-Hot Spot according to pre-configured some sub-district of user situation also, the focus value of constant Hot Spot or constant non-Hot Spot can be a specific steady state value, such as: when the scope of focus value dynamic change is 1～0x7D, the focus value that constant Hot Spot, constant non-Hot Spot can be set respectively is 0x7F, 0x7E, and no longer dynamically change etc.
Here, when normally group call mode was configured to the dynamic assignment resource, the focus value was effective, if group call mode is not the dynamic assignment resource, then MSC or GCR will ignore the focus value.
Whether the focus value can have the user according to group call cell in each group-calling process by MSC or GCR, upgrade, the mode of specific implementation can have multiple, the sub-district that the group-calling service user is arranged such as can discharge for: group calling the time, its focus value increases on former basis, reached maximum Cmax if be defined as this sub-district focus value, then no longer increased; Group calling does not have group-calling service user's sub-district focus value to reduce on former basis when discharging, and has reached minimum value Cmin if be defined as this sub-district focus value, then no longer reduces; In addition, if the focus value is specific steady state value, then MSC or GCR do not revise its focus value etc.
In the step 201, when MSC is defined as group call mode is the dynamic assignment resource, MSC can judge whether group call cell is Hot Spot according to the focus value of group call cell usually, such as: MSC or GCR judge that whether the focus value of group call cell is more than or equal to the focus critical value, if, then MSC determines that this group call cell is a Hot Spot, otherwise determines that this group call cell is non-Hot Spot.If pre-configured constant Hot Spot and constant non-Hot Spot, then MSC or GCR judge group call cell the focus value whether more than or equal to the focus critical value and be not equal to focus value corresponding to constant non-Hot Spot, if, then MSC determines that this group call cell is a Hot Spot, if the focus value of group call cell is less than the focus critical value and be not equal to focus value corresponding to constant Hot Spot, then MSC determines that this group call cell is non-Hot Spot, if the focus value of group call cell is corresponding to constant Hot Spot, then MSC determines that this group call cell is constant Hot Spot, if the focus value of group call cell is corresponding to constant non-Hot Spot, then MSC determines that this group call cell is constant non-Hot Spot.
After MSC determines Hot Spot or non-Hot Spot, can be according to sub-district focus situation dynamic assignment group calling passage.
MSC described in the step 201 or GCR are meant: the GCR among MSC self or the MSC or be independent of GCR outside the MSC.
Step 202:MSC is that Hot Spot adopts the mode of assigned resources immediately.
In the step 202, described assigned resources immediately can be the releasable mode of assigned resources and resource immediately, also the mode that can not discharge for assigned resources and resource immediately.
Step 203:MSC is the mode that non-Hot Spot adopts the delay assignment resource.
In the step 202, the mode of described delay assignment resource can be the mode of delay assignment A interface circuit, also can be the mode of delay assignment TCH.
In the embodiment of the invention, described MSC detects the unemployed affair user's of group calling sub-district, and normally MSC can detect have no property affair user's sub-district of group calling when group calling discharges.Such as: when group calling be configured to delay assignment TCH, immediately during assigned resources, in the group-calling process, if the notice MSC sub-district that MSC receives BSC no group-calling service user's VGCS ASS RESULT message is down then carried out record; If originally not having has had service-user under the sub-district of group-calling service, then BSC can rebulid TCH and connects, and with VGCSASS RESULT message informing MSC, at this moment MSC update mode information again.The VGCSASS RESULT message of described BSC is channel of the prior art (Channel) cell.
When group calling was configured to delay assignment A interface circuit, MSC thought that to the sub-district that connection is arranged service-user is arranged, and no professional user is thought in connectionless sub-district, and all sub-districts do not have connection, and then thinking does not have service-user in the group calling.
Here, when group calling was configured to delay assignment A interface circuit, MSC just can know that according to prior art there is connection which sub-district, and which sub-district does not have connection.
The present invention can also be used on any group system based on GSM except GT800, as GSM-R etc.Group calling of the present invention had both comprised VGCS, also comprised VBS.
The above is preferred embodiment of the present invention only, is not to be used to limit the scope of application of the present invention.
