Description
Technical field
The present invention relates to mobile communication technology, refer in particular to the method, the Apparatus and system that switch in a kind of mobile communication.
Background technology
At TD SDMA (TD-SCDMA; Time Division Synchronous Code Division Multiple Access) in the network; When wireless environment is relatively more abominable; Subscriber equipment (UE, User Equipment) to the process that Target cell switches, unnecessary repeatedly handoff failure problem occur through regular meeting from the cell-of-origin.
Fig. 1 is the sketch map that occurs unnecessary repeatedly handoff failure problem in the prior art.As shown in Figure 1, above-mentioned unnecessary repeatedly handoff failure problem can combine Fig. 1 to describe:
Wireless access network equipment (RNC) is selected a Target cell for UE, and sends first switching command to UE, and order UE switches to the said Target cell that is chosen.Carry cell ID (cell-id abbreviates sub-district ID as) and Transaction Identifier (ID) 1 in described first switching command.
After UE receives first switching command, accomplish switching, and after accomplishing switching, return corresponding first handoff completion message to RNC at Target cell to Target cell.Carry the affairs ID1 of first switching command in said first handoff completion message.
Because the abominable wireless environment and the repeatedly re-transmission of bottom, first switching command and corresponding first handoff completion message all will experience the bigger time delay of eating dishes without rice or wine.When making, the above-mentioned time delay of eating dishes without rice or wine wins handoff completion message within the stand-by period of RNC scope (being tolerance) still during no show RNC; RNC will think that this handoff procedure is overtime or fail; Therefore RNC can send second switching command that carries sub-district ID and affairs ID2 to UE, orders UE to switch to the said Target cell that is chosen once more.Sub-district ID entrained in said first switching command and second switching command is identical, but entrained affairs ID is different.
The influence of time delay owing to eat dishes without rice or wine; RNC might just receive first handoff completion message that UE sends after sending above-mentioned second switching command; But because the affairs ID2 of second switching command that the entrained affairs ID1 of first handoff completion message and RNC have just sent is different; Therefore RNC will abandon the first received handoff completion message, and and do not know that UE has accomplished switching according to first switching command.Similar; When RNC does not receive within the stand-by period scope and the corresponding handoff completion message of second switching command yet; Then RNC will think the overtime or failure of this handoff procedure, so RNC can send the 3rd switching command to UE, and affairs ID3 and sub-district ID have been carried in this order.
And for UE, after the switching that is accomplished to Target cell and having sent first handoff completion message, UE thinks that handoff procedure is successful, and the sub-district at the current place of UE (being above-mentioned Target cell) is new sub-district.At this moment because activationary time do not arrive, the former configuration of UE (for example physical channel resources etc.) still effectively, so UE still can receive second switching command that RNC sends.When the UE in being in new sub-district received second switching command, UE found that the second received switching command is that order oneself switches to own residing new sub-district.Therefore, UE will think that described second switching command is wrong order, so return first switch failure information of having carried affairs ID2 to RNC.In like manner, when UE received the 3rd switching command that RNC sends, RNC returned second switch failure information of having carried affairs ID3.
When receiving first switch failure information or second switch failure information, RNC will think the failure of above-mentioned handoff procedure, be because eat dishes without rice or wine the misunderstanding that time delay caused and do not know real failure cause.And because the existence of the time delay of eating dishes without rice or wine, the process of this mutual misunderstanding repeatedly repeats to occur possibly, for example; RNC continues to send switching command to UE, and receive switching command UE and return switch failure information once more, and can the rest may be inferred; Consequently, when UE successfully accomplished switching, RNC but abandoned the received handoff completion message that UE sent; And takeing for handoff procedure according to the switch failure information that UE sent fails; Continue to send switching command, therefore cause RNC and UE whether successfully to exist and misread, thereby bring unnecessary repeatedly handoff failure problem for handoff procedure.
For aforesaid unnecessary repeatedly handoff failure problem, can solve the stand-by period (promptly tolerating the limit) of handoff completion message through prolonging RNC in the prior art.Though above-mentioned solution can be avoided the appearance of unnecessary repeatedly handoff failure problem to a certain extent; But the stand-by period that prolongs handoff completion message also will bring adverse influence; For example, at waiting time, RNC has no chance to select new Target cell; And because in most of the cases, the handoff requirement that is produced generally all is more urgent, therefore, when switching command or corresponding handoff completion message really produce loss situation, waits for still not skimble-skamblely for a long time, and is high cost.

Embodiment
For making the object of the invention, technical scheme and advantage express clearlyer, the present invention is remake further detailed explanation below in conjunction with accompanying drawing and specific embodiment.
Embodiments of the invention provide the method for switching in a kind of mobile communication; This method only need be controlled (RRC) message to Radio Resource and make amendment; And the processing procedure of RNC and UE done minimum change, can solve above-mentioned unnecessary repeatedly handoff failure problem.
According to third generation partner program (3GPP; Third Generation Partnership Project) the RRC message abstract syntax (ASN.1) in 25.331 standards; In switching command message (for example; Radio bearer reallocation message, transmission channel reallocation message or physical channel reallocation message etc.) afterbody, all use sub-district ID to come the recognition objective sub-district.Therefore; Embodiments of the invention will solve above-mentioned unnecessary repeatedly handoff failure problem through the sub-district ID expansion partly to above-mentioned switching command; The i.e. afterbody of the switching command after above-mentioned expansion; Carry the Target cell that cell-of-origin sign (source-cell-id abbreviates cell-of-origin ID as) and Target Cell Identifier (target-cell-id abbreviates Target cell ID as) are used for representing the cell-of-origin and the place after the switching at the place of user equipment (UE) before switching respectively.Owing to carried above-mentioned cell-of-origin ID and Target cell ID in the switching command; When cell-of-origin ID that is therefore stored among the cell-of-origin ID of UE in current switching command and Target cell ID and the UE and Target cell ID are consistent; To send handoff completion message with the affairs ID of current switching command, notice RNC switching is accomplished.So; RNC improves at the probability that certain tolerance receives the corresponding handoff completion message that UE returns in limit greatly; Make RNC know that handoff procedure completes successfully, so the RNC switching command of will not redispatching, thereby above-mentioned unnecessary repeatedly handoff failure problem solved.
Fig. 2 is the sketch map that solves unnecessary repeatedly handoff failure problem in the embodiment of the invention.As shown in Figure 1, in an embodiment of the present invention, between RNC and the UE message interaction process be described below:
Based on UE to the measurement result of adjacent area and decision algorithm or other Consideration of RNC; RNC is that UE selects a Target cell; And (for example send first switching command to UE; Radio bearer reallocation message, transmission channel reallocation message or physical channel reallocation message etc.), order UE switches to the said Target cell that is chosen.Carry cell-of-origin ID, Target cell ID and affairs ID1 in described first switching command.
(for example receive first switching command; The physical channel reallocation message) after, UE accomplishes the switching to Target cell according to first switching command, and after accomplishing switching; Cell-of-origin ID that carries in the bank switching order and Target cell ID (promptly having switched the ID of sub-district, the current place of UE, back); Return corresponding first handoff completion message (for example, the physical channel reprovision is accomplished message) to RNC then, carry the affairs ID1 of first switching command in said first handoff completion message.
Because the abominable wireless environment and the repeatedly re-transmission of bottom, first switching command and corresponding first handoff completion message all will experience the bigger time delay of eating dishes without rice or wine.When making, the above-mentioned time delay of eating dishes without rice or wine wins handoff completion message within the stand-by period of RNC scope (being tolerance) still during no show RNC; RNC will think that this handoff procedure is overtime or fail; Therefore RNC can send second switching command that carries cell-of-origin ID, Target cell ID and affairs ID2 to UE, orders UE to switch to the Target cell that Target cell ID is identified once more.Entrained Target cell ID can be identical in said first switching command and second switching command, also can be inequality.For example, RNC can carry out switch decision once more, the select target sub-district, so the selected once more Target cell of RNC maybe be identical with selected Target cell in article one switching command, also maybe be different.
The influence of time delay owing to eat dishes without rice or wine; RNC might just receive first handoff completion message that UE sends after sending above-mentioned second switching command; But because the affairs ID2 of second switching command that the entrained affairs ID1 of first handoff completion message and RNC have just sent is different, so RNC will abandon the first received handoff completion message.Similar; When RNC does not receive within the stand-by period scope and the corresponding handoff completion message of second switching command yet; Then RNC will think that this handoff procedure is overtime or fail, so RNC will send the 3rd switching command that carries cell-of-origin ID, Target cell ID and affairs ID3 to UE.
And for UE; After the switching that is accomplished to Target cell and having sent first handoff completion message; UE thinks that handoff procedure is successful, and the sub-district at the current place of UE (promptly switching the sub-district at UE place after accomplishing, just the Target cell in first switching command) is new sub-district.At this moment; Because activationary time does not arrive; The former configuration of UE (for example physical channel resources etc.) still effectively; When the UE in being in new sub-district received second switching command, whether the current area ID (i.e. Target cell ID in first switching command) that is stored among the Target cell ID in second switching command that UE will newly receive and the UE was identical.If different, explain that then RNC order UE switches in another the Target cell, so UE will think that second switching command is a new switching command, and switch accordingly by second switching command; If identical, second switching command switching command that might to be RNC send owing to do not receive first handoff completion message once more then is described, so whether the cell-of-origin ID that UE continues to be stored among cell-of-origin ID and the UE in second switching command relatively is consistent.If it is consistent; Then UE can know that its first handoff completion message that sends is not received by RNC in time; Perhaps first handoff completion message has been lost in transmission course, and at this moment, UE sends second handoff completion message once more with the affairs ID2 of second switching command; If inconsistent, then UE thinks that described second switching command is wrong switching command, therefore returns switch failure information (for example physical channel reprovision failed message) to RNC, and cause value entrained in this message is: reprovision in the time of incompatible.
Because the abominable situation of wireless environment or the other factors of transmission course, UE may repeatedly receive switching command (as shown in Figure 2, UE has received three switching commands), and UE can handle received switching command according to above-mentioned processing method.
Because the current area ID that UE is only stored among the Target cell ID in switching command and the UE is identical, and the cell-of-origin ID that is stored among cell-of-origin ID in the switching command and the UE just can return switch failure information to RNC when inconsistent; And when the cell-of-origin ID that is stored among the cell-of-origin ID in the switching command and Target cell ID and the UE and Target cell ID are consistent; UE will send corresponding with it handoff completion message with the affairs ID of the switching command that receives recently; So; RNC is in certain time period after having sent certain switching command (promptly in the tolerance limit) receives the probability of certain corresponding bar handoff completion message with it that UE returns and improves greatly; And the affairs ID of this handoff completion message is identical with the affairs ID of the switching command that RNC has just sent, and RNC will think that handoff procedure completes successfully this moment, can not send switching command once more.Therefore, can not cause RNC and UE whether successfully to exist and misread, thereby solve unnecessary repeatedly handoff failure problem of the prior art for handoff procedure.And what send to UE as RNC is in the sub-district during reallocation message, then need not carry cell-of-origin ID and Target cell ID in the described sub-district in the reallocation message.
Fig. 3 is the method flow diagram that solves unnecessary repeatedly handoff failure problem in the embodiment of the invention.As shown in Figure 3, the method that solves unnecessary repeatedly handoff failure problem in the embodiment of the invention comprises following step:
Specifically, RNC will for UE selects a Target cell, and send switching command to UE according to UE to the measurement result of adjacent area and decision algorithm or other Consideration of RNC, carry cell-of-origin ID and Target cell ID in this switching command.
Step 302 after UE receives switching command, judges whether and need switch that switch if desired, then execution in step 303; Otherwise, execution in step 304.
Whether the Target cell ID in the ID that specifically, UE can be through UE current area relatively and the switching command identical needs to judge whether switching.If different, then the UE judgement need be switched, execution in step 303; If identical, then the UE judgement need not switched, directly execution in step 304.
Specifically, in this step, if RNC receives and the corresponding handoff completion message of said switching command in the patient time scope, then RNC judges that handoff procedure completes successfully; Otherwise RNC judges also completion of handoff procedure, returns step 301.
