Description
Technical field
The present invention relates to mobile communication technology, refer in particular to a kind of method, Apparatus and system of up soft handover.
Background technology
Commercial at present code division multiple access (CDMA, Code Division Multiple Access) system generally all supports polytype switching, main switching type has: direct-cut operation, soft handover and More Soft Handoff, described direct-cut operation is meant that Traffic Channel has the handoff procedure of instantaneous interruption in the business of switching; Soft handover is meant that when Radio Link need increase or discharge, subscriber equipment (UE) kept being connected of at least one wireless links with network all the time; More Soft Handoff then is meant the switching that has in same base station between the different sectors of same frequency.And then continued to use soft hand-off among most of former IS-95 standard and the CDMA2000 in Wideband Code Division Multiple Access (WCDMA) (WCDMA, the Wideband Code Division Multiple Access) system.For the UE that is in WCDMA system cell edge, soft handover is a kind of normality, and promptly UE almost is under the soft changing state always, thereby can guarantee the continuity and the stability of user's communication.
Forever wrap in line (CPC, Continues Packet Connection) technology is one of very important technology in the R7 agreement, by using the discontinuous transmission (DTX in the CPC technology, DiscontinuousTransmission) technology, can make as ascending reinforced special channel (E-DCH, when free of data sends Enhanced DedicatedChannel), need not to continue again to send unnecessary Dedicated Physical Control Channel (DPCCH, Dedicated Physical Control Channel) signaling, and only need discontinuous transmission DPCCH to happen suddenly, to keep communication link, it can not interrupted, thereby reduced unnecessary uplink transmitted power and uplink interference, increased up user's number.Therefore, the CPC technology can be used for the structure of the whole network R7 sub-district, to improve whole network capacity amount; The hot zones that perhaps the CPC technology is used for high traffic characteristics covers.And for the latter, the R7 sub-district of CPC and the phenomenon of the R6 sub-district coexistence of not supporting CPC in general can occur supporting, and the scene that UE switches between R7 sub-district and R6 sub-district takes place.
In existing technical scheme, can adopt hard handover approach to realize the switching of UE between R7 sub-district and R6 sub-district.Described direct-cut operation is meant when travelling carriage generation handover, disconnects earlier and the getting in touch of old sub-district, and sets up the handoff procedure of contact again with new sub-district.Fig. 1 is that UE realizes the schematic diagram that switch the sub-district by direct-cut operation in the prior art.As shown in Figure 1, switching to the R6 sub-district with UE from the R7 sub-district is example, and UE realizes that by direct-cut operation the sub-district switching comprises step as described below in the prior art:
101: when the UE in being in the R7 sub-district found new sub-district (R6 sub-district), UE reported the new sub-district of being found by the R7 sub-district to wireless access network equipment (RNC).At this moment, the base station in UE and the R7 sub-district (Node B) all keeps the R7 configuration, and the CPC in the R7 configuration is in the state of activation, i.e. R7 configuration support CPC technology.
102:RNC becomes the R6 configuration with newfound R6 cell configuration, and the Radio Link of increase and R6 minizone; By the physical channel reconfiguration course, UE is switched to the R6 sub-district then.
The 103:UE disconnection is connected with the R7 sub-district, connects with the R6 sub-district, regains the physical channel resources between UE and the R7 sub-district, thereby finishes direct-cut operation.
The characteristics of the method for above-mentioned direct-cut operation connect for having no progeny earlier, so the advantage of direct-cut operation is that algorithm is simple, the resource utilization height, and signaling consumption is few.But the WCDMA system is an a kind of self-interference system, therefore, be by the shortcoming with the switching of direct-cut operation realization UE from the R7 sub-district to the R6 sub-district frequently: handover delay is longer, and handover success rate is lower, and cutting off rate is higher, therefore will influence the subjective feeling of user's communication, and cause call drop easily.So, when carrying out network design, should avoid the generation of direct-cut operation as far as possible.
In existing technical scheme, can adopt the mode of soft handover to realize the switching of UE between R7 sub-district and R6 sub-district, promptly the mode of reshuffling by physical channel becomes the R7 cell configuration sub-district of non-CPC (promptly not supporting the CPC technology), then the R6 sub-district is added Active Set, thereby realize the soft handover of UE between R7 sub-district and R6 sub-district.Fig. 2 is that UE realizes the schematic diagram that switch the sub-district by soft handover in the prior art.As shown in Figure 2, switching to the R6 sub-district with UE from the R7 sub-district is example, and UE realizes that by soft handover the sub-district switching comprises step as described below in the prior art:
201: when the UE in being in the R7 sub-district found new sub-district (R6 sub-district), UE reported the new sub-district of being found by the R7 sub-district to wireless access network equipment (RNC).At this moment, the base station in UE and the R7 sub-district (Node B) all keeps the R7 configuration, and the CPC in the R7 configuration is in the state of activation.
202:RNC becomes R6 configuration (promptly using the cell of R6) with newfound R6 cell configuration, and the Radio Link of increase and R6 minizone; Realize wireless link reconfigured to the R7 sub-district original R7 cell configuration being become R6 configuration (promptly using the cell of R6) by the physical channel reconfiguration course then.Because the R7 allocating default is supported the CPC technology, and the CPC technology is not supported in the R6 configuration, therefore the R7 cell configuration is become the operation of R6 configuration can be referred to as the CPC operation, thereby makes original R7 sub-district to send control signaling continuously in ascending control channel; Then, going to former R7 sub-district behind the CPC is that UE carries out physical channel and reshuffles, and UE is configured to the R6 configuration, removes CPC.In addition, in this step, will attempt connecting in the R6 sub-district that increases newly with UE.
203:RNC is by the instruction of R7 sub-district to UE transmission activating set updating, and UE adds the R6 sub-district according to this instruction in Active Set; At this moment, the R6 sub-district begins to receive the uplink information of UE, and therefore, UE will return to RNC by the message that renewal is finished in the R6 sub-district.
204: when satisfying the switching judging condition, once more to the instruction of UE transmission activating set updating, UE switches to the R6 sub-district according to this instruction to RNC, and deletes the R7 sub-district in Active Set by the R7 sub-district.
The 205:UE disconnection is connected with the R7 sub-district, connects with the R6 sub-district, thereby finishes soft handover.
In the step 202 in above-mentioned soft handover method, when the physical channel reconfiguration course of UE still imperfect tense, UE still keeps the R7 configuration, and the CPC technology still is in state of activation.Therefore, when the trial of R6 sub-district connects with UE, because UE still uses the CPC technology to send the DPCCH signaling discontinuously, and the R6 sub-district that increases newly is not owing to support the CPC technology, therefore can't correctly discern the DPCCH signaling of the discontinuous transmission of UE, and may cause erroneous judgement, think self with UE between be connected existing problems or connection failure, thereby may cause the uplink loss between R6 sub-district and the UE, reduced R6 sub-district and UE and can't carry out synchronous probability, thereby increased the time delay of carrying out soft handover by up channel.In addition, owing in above-mentioned soft handover method, used the bigger physical channel reconfiguration course of time delay, therefore also will introduce bigger time delay inevitably.

Wherein, above-mentionedly the CPC deactivating operation is carried out in UE and R7 sub-district comprise: UE and R7 sub-district are carried out the CPC deactivating operation by the signaling that comprises the deexcitation cell.And the above-mentioned signaling that comprises the deexcitation cell can be to comprise deexcitation cell radio link reconfiguration signaling, comprise the Radio Link request of setting up of deexcitation cell, the activating set updating signaling that comprises the deexcitation cell and High-Speed Shared Control Channel (HS-SCCH, High Speed Shared Control Channel) signaling etc.
Below with reference to specific embodiment the method for above-mentioned up soft handover is further introduced.
Embodiment one:
Fig. 3 is the flow chart of up soft handover method in the embodiment of the invention one.As shown in Figure 3, switching to the R6 sub-district from the R7 sub-district with UE is example, and up soft handover method can comprise the steps: in the embodiment of the invention one
301, when the UE in being in the R7 sub-district found new sub-district (R6 sub-district), UE reported the new sub-district of being found by the R7 sub-district to RNC.At this moment, the base station in UE and the R7 sub-district all keeps the R7 configuration, and all supports the CPC technology, i.e. CPC in the R7 configuration is in state of activation.
302, RNC is that the CPC deactivating operation is carried out in the R7 configuration of R7 sub-district by the radio link reconfiguration signaling, promptly keep the cell of R7 configuration, but CPC is set to unactivated state, promptly uses the continuous sending mode in the CPC technology; Then, the base station in the R7 sub-district is that UE carries out the CPC deactivating operation by High-Speed Shared Control Channel (HS-SCCH, High Speed Shared Control Channel) physics signaling.
In this step, RNC also can send the signaling (this signaling can be an activating set updating signaling etc.) that comprises a deexcitation cell to the R7 sub-district, and the R7 sub-district is transmitted to UE with this activating set updating signaling.This deexcitation cell is set to deactivation status, is used to indicate R7 sub-district and UE to carry out the CPC deactivating operation.R7 sub-district and UE carry out the CPC deactivating operation according to this activating set updating signaling.By the method, RNC can directly notify UE to carry out CPC deexcitation or CPC activation manipulation.
In addition, the deexcitation cell can be a flag bit, and what R7 sub-district and UE can be according to this flag bits is worth knowing that carrying out the CPC activation manipulation still carries out the CPC deactivating operation.For example: the value of flag bit is 0 o'clock, and expression need be carried out the CPC activation manipulation; The value of flag bit is 1 o'clock, and expression need be carried out the CPC deactivating operation.The implication of the value of this flag bit also can be set in advance according to actual conditions.
303, RNC becomes the R6 configuration with newfound R6 cell configuration, and the Radio Link of increase and R6 minizone; In addition, in this step, will attempt connecting in the R6 sub-district that increases newly with UE.
304, RNC is by the instruction of R7 sub-district to UE transmission activating set updating, and UE adds the R6 sub-district according to this instruction in Active Set; At this moment, the R6 sub-district begins to receive the uplink information of UE, and therefore, UE will return to RNC by the message that renewal is finished in the R7 sub-district.
305, when satisfying the switch decision condition, once more to the instruction of UE transmission activating set updating, UE switches to the R6 sub-district according to this instruction to RNC, and deletes the R7 sub-district in Active Set by the R7 sub-district.
306, the UE disconnection is connected with the R7 sub-district, connects with the R6 sub-district, thereby finishes soft handover.
In the step 302 in above-mentioned up soft handover method, owing to need not to come the operation of removing CPC for R7 sub-district and UE by the physical channel reconfiguration course, and by the radio link reconfiguration signaling for as carrying out the CPC deactivating operation in the R7 sub-district of Serving cell, and be that UE carries out the CPC deactivating operation by HS-SCCH physics signaling; Or directly the activating set updating signaling by having increased the deexcitation cell to after carrying out the CPC deactivating operation as the R7 sub-district of Serving cell or UE, can make UE and as the R7 sub-district of Serving cell all the CPC technology be set to unactivated state, thereby realize compatible with initiate R6 sub-district.In above-mentioned operation, because the time delay that radio link reconfiguration signaling, HS-SCCH physics signaling and the activating set updating signaling of deexcitation cell of having increased are introduced is far smaller than the time delay that the physical channel reconfiguration course is introduced, therefore by above-mentioned up soft handover method, can significantly reduce UE from the R7 sub-district to the time delay for switching the R6 sub-district.
Embodiment two:
In the up soft handover method in embodiment one, in step 306, UE will disconnect and being connected of R7 sub-district.And in the application scenarios of reality, also can not disconnect and being connected of R7 sub-district, thereby make when UE can can't satisfy situations such as service quality in the R6 sub-district that increases newly, switch to the original R7 sub-district from the R6 sub-district once more.
