Embodiment
For making the object, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.
Fig. 2 is the schematic flow sheet of switch managing method embodiment provided by the invention.Shown in Fig. 3, embodiment of the method comprises:
Step 201, obtain the directed retry information that mobile terminal (MS) need to be switched to from cell-of-origin Target cell, this directed retry information comprises that described cell-of-origin and described Target cell are the information of being managed by same base station controller (BSC);
Step 202, directly makes handoff response to the BSC of the described cell-of-origin of management.
Embodiment of the method provided by the invention, in the time of BSC inner orientation retry, compared with prior art, the information that same BSC manages by obtaining cell-of-origin and Target cell, minimizing is mutual with Target cell BSC's of living in, reaches and has reduced the mutual of signaling, has improved the speed of switching.
Below method provided by the invention is described further:
Fig. 3 is the structural representation of switch managing method application example provided by the invention.The application example of method shown in Fig. 3 comprises:
S301, in call establishment, MSC SERVER initiates assignment request to BSC, requires to distribute channel and the resource of A mouth.
S302, BSC detects when MS need to be switched to Target cell from cell-of-origin, judges whether this Target cell is managed by this locality; If so, perform step S403.
In this step, BSC detects that MS need to be switched to Target cell from cell-of-origin, first judge that whether this Target cell is by local management, because BSC records whole communities that this locality can be managed, if this Target cell belongs to the community that can manage of local record, represent that this Target cell is by local management, determine that this MS need to initiate the directed retry in this BSC, cell-of-origin and Target cell are all by local management; Wherein the reason of same BSC initiation directed retry flow process can be that the appearance of calling community is congested, can be also to optimize cell radio resource.The trigger condition of wherein optimizing cell radio resource is that application example of the present invention newly increases, wherein can be specially Radio Resource load high for the trigger condition of this optimizing cells resource, and wherein in prior art, the judgment mode of Radio Resource load condition is all applicable to the present invention.
S303, the request that BSC need to be switched to from cell-of-origin Target cell to MSC SERVER transmission MS under directed retry condition, comprises the information that cell-of-origin and Target cell are managed by same BSC.
In this step, BSC detects that MS need to be switched to Target cell from cell-of-origin, first judges that whether this Target cell is by local management, if so, determines that this MS need to initiate the directed retry in this BSC, and cell-of-origin and Target cell are all by local management; Wherein the reason of same BSC initiation directed retry flow process can be that the appearance of calling community is congested, can be also to optimize cell radio resource.The trigger condition of wherein optimizing cell radio resource is that application example of the present invention newly increases, wherein can be specially Radio Resource load high for the trigger condition of this optimizing cells resource, and wherein in prior art, the judgment mode of Radio Resource load condition is all applicable to the present invention.
Wherein sending this handover information can be in the following way:
Mode one: send and assign failure response message to MSC SERVER, this appointment failure response message comprises that failure cause is the information of directed retry, then transmission comprises that this MS is switched to the request of Target cell from cell-of-origin;
Mode two: directly send this MS and be switched to from cell-of-origin the request of Target cell, this request comprises that switch reasons is the information of directed retry.
Aforesaid way one and two is compared, can find out that mode two and mode one can reach the object that has MS need to switch because of the reason of directed retry in notice MSC SERVER this locality, wherein in mode one, BSC sends by two message, be respectively the message of assigning failure response message and request to switch, and the message of only switching with request in mode two, and the message of assigning the failure cause carrying in failure response message to switch by this request in mode one is sent, specifically be carried in the message that this request switches in untapped field, as extended field or reserved field, can obtain thus mode two and simplify appointment failure response message, reduce the exchange flow process of information.
In above-mentioned two kinds of modes, the information that cell-of-origin and Target cell are managed by same BSC can be transmitted by untapped field.For example select a field, the numerical value that configures this field is 0 o'clock, and expression is that cell-of-origin and Target cell are managed by same BSC; Be 1 o'clock, expression is that cell-of-origin and Target cell are not to be managed by same BSC.Receive after this request at MSC, can determine whether this cell-of-origin and Target cell are managed by same BSC according to the numerical value in this field.
Further, for avoiding the problem because the amendment of existing message being occurred to updating network element equipment, the message format of the message that in this step, request is switched with in protocols having, be applied to that to call out the form of the outside handover request of request switching while entering stable state identical, it not traditional form across the handover request in BSC switching flow, and this outside handover request is applied in call establishment, thereby make BSC in call establishment according to this external request message, just can determine that the cell-of-origin of this switching and Target cell are managed by same BSC, simple and convenient, adopt the message format having specified in protocols having to send simultaneously, realize simply, ensured the compatibility of message between system.
S304, the definite cell-of-origin of the request for switching and Target cell that MSC SERVER sends from BSC are managed by same BSC, directly make handoff response to BSC;
In this step, MSC SERVER judges whether the message that this request is switched is outside handover request, if so, determines and is managed by same BSC.
Its peripheral handover request is from traditional handover request, message format is different, outside handover request and traditional handover request are two kinds of different type of messages, and whether MSC SERVER can judge according to the type of message mark in the message of receiving is outside handover request message.
If the message that this request is switched is not outside handover request, but traditional handover request, MSC SERVER processes according to traditional switching flow.
Through the judgement of this step, if managed by same BSC, it not the switching mode across BSC, MSC SERVER just without according in prior art across the negotiation flow process of switching with place, Target cell BSC in BSC switching flow (S104 shown in Fig. 1 and S105), reduced the interaction flow of information.
In this step, judge the local switching that whether can support described BSC request, if can support, notify BSC to allow this MS to switch; Otherwise notice BSC refuses this MS and switches.The reason of wherein not supporting this switching may be that carrying is set up unsuccessfully or wirelessly chooses suitable encoding and decoding.
Optionally, in the time allowing this MS to switch, the encoding and decoding of also notifying BSC that the calling of this MS is used become half rate from full rate, with just revise the speed of encoding and decoding in prior art in the time that stable state is carried out in calling compared with, by existing transmission mechanism, revise in advance the speed of encoding and decoding, overcome the problem that existing middle call set-up time causes existing in wireless signal Hao community a large amount of callings that use full rate encoding and decoding when long, improve the efficiency that Radio Resource uses, reached the object of optimizing local resource.
Optionally, in the time that this MS of refusal switches, control this BSC repeating transmission MS is switched to Target cell request from cell-of-origin, prevent this BSC frequent message from this request switching to this locality that retransmit after handoff failure and cause the heavier problem of local burden, prevent the problem that other effective requests can not receive in time, ensure local disposal ability.
Wherein controlling this BSC retransmits MS is switched to Target cell request from cell-of-origin and specifically comprises:
Be switched to the request of Target cell from cell-of-origin by again sending MS to BSC transmission assignment request triggering BSC; Or,
Stop described BSC and again send MS and be switched to from cell-of-origin the request of Target cell by discharging the calling of this MS.
If allow this MS to initiate to switch, carry out S305～S311.
S305, BSC sends wireless switching command to MS, and notice MS switches.
S306, MS is linked into Target cell, sends wireless switching detection message to BSC.
S307, BSC sends switching detection message to MSC SERVER, and this MS of notice MSC SERVE has been linked into Target cell.
S308, MS sends the wireless BSC that handovers complete message to.
S309, BSC sends handoff completion message to MSC SERVER, and notice MSC SERVER switching completes.
S310, continues call establishment.
S311, call setup completes, and calls out and enters stable state.
In application example provided by the invention, in the time that BSC carries out directed retry, compared with prior art, the information that same BSC manages by obtaining cell-of-origin and Target cell, minimizing is mutual with Target cell BSC's of living in, reaches and has reduced the mutual of signaling, has improved the speed of switching.Under normal circumstances, timing retry accesses community while being applied to call setup and occurs congested scene, can be call diversion to other comparatively idle communities by directed retry.Adopt after the present invention, due to the simplification of processing and the minimizing of handover delay, directed retry not only can be applied to the scene of small area jam, can also be used for the optimization of Radio Resource.By directed retry, in reasonably distributing radio resource of call establishment stage, improve the handling capacity of system.
What directed retry adopted in the prior art is the switching flow across BSC, because this traditional switching flow is processed comparatively complicated, handoff delay is relatively large, therefore be not suitable for being applied in the scene of frequent generation, be conventionally applied to not recurrent community and occur changing when congested the scene of calling out access community.
Adopt method of the present invention, due to the reduction of outside switching flow signaling consumption and handover delay, directed retry speed can have comparatively significantly raising, and directed retry not only can be applied to the scene of small area jam like this, can also be used to the object that cell radio resource is optimized.In the time that cell radio resource is optimized, can improve cell radio resource utilance by directed retry frequently.
In sum, adopt the inventive method, can effectively improve the speed of directed retry, and due to the raising of directed retry speed, can expand the scope of directed retry application.
