Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to the method and the device of a kind of handle mobile terminal concurrent cell update in cell switch process.
Background technology
Third generation universal mobile telecommunications system (Universal Mobile Telecommunications System, UMTS) basic network topology is by portable terminal (User Equipment, UE), UMTS Terrestrial radio access network (UMTS Terrestrial Radio Access network, UTRAN) and core net (CoreNetwork, CN) three parts are formed.UTRAN comprises that (Radio Network Controller, RNC) two nodes, RNC mainly are responsible for the management of wireless access network, and NodeB mainly is responsible for the transmitting-receiving of wireless signal for base station (NodeB) and radio network controller.
UMTS adopts cell cellular structural planning field strength coverage territory.The covering radius of each sub-district is generally 1-20km, and available less transmitting power realizes two-way communication, and several sub-districts constitute larger area and cover, and adopts this method to cover unlimited vast zone.Because the complexity of geographical environment, edge at two neighbor cells, facilities such as the higher buildings that may exist in its overlay area, viaduct form the shadow region or wireless signal are caused very high attenuation, and this overlay area is called the abominable zone of wireless environment.When switch the sub-district that UE carries out in the abominable zone of wireless environment from the cell-of-origin to the Target cell, perhaps UE wireless environment in cell switch process worsens, cell-of-origin downlink signal quality deterioration may occur or not have downstream signal at all, UE detects cell-of-origin quality of down wireless link deterioration or the cell-of-origin is in desynchronizing state, can initiate cell update, at this moment request RNC the situation of UE concurrent cell update in cell switch process just occurred for this portable terminal distributes new Radio Resource.The target of UE initiation cell update may be cell-of-origin or the Target cell in the cell switch process, also may be other neighbor cell, and this is that UE determines through calculating.
UE switches basic procedure as shown in Figure 1 in the sub-district from the cell-of-origin to the Target cell in the prior art, comprising:
S101～S102, UE are to the RNC reporting measurement reports, and when measurement report satisfied the sub-district switching condition, the inner Radio Resource of RNC application was used for setting up Radio Link between UE and Target cell;
S103～S104, RNC set up the Radio Link between Target cell and the UE, RNC sends Radio Link to the NodeB of Target cell and sets up request RL SETUP REQUEST, after the NodeB of Target cell receives Radio Link foundation request, according to the RNC assigned radio resource is the UE collocation wireless link, sends Radio Link to RNC after configuration is finished and sets up response RL SETUP RESPONSE;
Establish wired link between the NodeB of S105～S106, RNC and Target cell, this wire link is used between the NodeB of RNC and Target cell transmission to the wireless signal of UE transmitting-receiving, RNC sends wire link foundation to the NodeB of Target cell and asks ESTABLISH REQUEST, and the NodeB of Target cell receives wire link and sets up the request back to RNC transmission wire link foundation response ESTABLISHCONFIRM;
S107, RNC are that Target cell is newly applied for local resource, are used for the signal on wire link between the NodeB of RNC internal transmission and Target cell, and are the new configuration service face of Target cell;
S108, RNC send physical channel reconfiguration message PHYSICAL CHANNEL RECONFIGRATION via the NodeB of cell-of-origin to UE, trigger the physical channel that uses new configuration between RNC and the UE;
If the physical channel configuration parameter of new configuration is correct and obtain the support of UE, then carry out following steps after the S108:
The NodeB of S109, Target cell sends Radio Link to RNC and rebuilds upright message RADIO LINKRESTORATION, shows that the physical channel between RNC and the UE switches to physical channel via the new configuration of Target cell from the physical channel via the cell-of-origin;
S110a, UE reshuffle success message PHYSICAL CHANNEL RECONFIGURATION COMPLETE via the NodeB of Target cell to RNC transmission physical channel, and the sub-district handover success of expression UE side is finished;
The sub-district was switched and also all not to be finished this moment, because for the RNC side, received after physical channel that UE sends reshuffles success message, also will continue to carry out sub-district handover success flow process, comprising:
S111a, RNC remove the service surface for the cell-of-origin configuration, are recovered as the local resource of cell-of-origin application;
Radio Link between S112a～S113a, RNC deletion cell-of-origin and the UE, RNC sends Radio Link removal request RL DELETION REQUEST to the NodeB of cell-of-origin, and the NodeB of cell-of-origin sends Radio Link deletion response RL DELETIONRESPONSE to RNC after receiving the Radio Link removal request;
Discharge wire link between the NodeB of S114a～S115a, RNC and cell-of-origin, RNC sends wire link release message RELEASE to the NodeB of cell-of-origin, and the NodeB of cell-of-origin sends wire link to RNC and discharges affirmation response RELEASE CONFIRM.
If UE does not support the physical channel of new configuration or the configuration parameter mistake of physical channel, then carry out following steps after the S108:
S110b, UE send physical channel reconfiguration failure message via the NodeB of cell-of-origin to RNC, and the sub-district handoff failure of expression UE side is finished;
The sub-district was switched and also all not to be finished this moment because for the RNC side, receive the physical channel reconfiguration failure message that UE sends after, also to continue to carry out the sub-district handover failure procedures, comprising:
S111b, RNC remove the service surface for the new configuration of Target cell, are recovered as the local resource of the new application of Target cell;
Newly-established Radio Link between S112b～S113b, RNC deletion Target cell and the UE, RNC sends Radio Link removal request RL DELETION REQUEST to the NodeB of Target cell, and the NodeB of Target cell sends Radio Link deletion response RLDELETION RESPONSE to RNC after receiving the Radio Link removal request;
Discharge wire link between the NodeB of S114b～S115b, RNC and Target cell, RNC sends release message RELEASE to the NodeB of Target cell, and the NodeB of Target cell sends to discharge to RNC and confirms response RELEASE CONFIRM.
The physical channel of messaging comprises designated lane RB2 and public passage between carrying RNC and the UE, and designated lane RB2 has only the operable information receiving and transmitting passage of this UE between UE and the RNC, and designated lane RB2 is divided into downlink dedicated passage and up designated lane.The downlink dedicated passage is used to transmit the physical channel reconfiguration message that RNC sends to UE etc., and the physical channel that up designated lane is used to transmit the expression sub-district handover success that UE sends to RNC is reshuffled the physical channel reconfiguration failure message of success message and expression sub-district handoff failure etc.Public passage be that all UE can use and RNC between the information receiving and transmitting passage, be used to transmit the cell update that cell update message CELL UPDATE that UE sends to RNC and RNC send to UE and confirm CELL UPDATE CONFIRM etc.
The basic procedure of cell update as shown in Figure 2 in the prior art, UE sends cell update message CELL UPDATE to UTRAN, send cell update to UE after the cell update message that RNC processing UE among the UTRAN sends and confirm CELL UPDATE CONFIRM, and by carrying physic channel information " Physical channel information elements " is designated as new Radio Resource from its distribution to UE, UE receives the back and reshuffles success message to UTRAN transmission physical channel, and the expression cell update is finished.The triggering reason of cell update has multiple, for example reenters service area, Radio Link control (Radio LinkControl, RLC) fatal error, periodic cell update, sub-district gravity treatment, Radio Link Failure etc.
When portable terminal in cell switch process during concurrent cell update, processing method of the prior art as shown in Figure 3, UE sends cell update message to UTRAN in cell switch process, carry former be because Radio Link Failure, the RLC fatal error; RNC among the UTRAN sends resource release message RRC CONNECTION RELEASE to UE, is released to whole resources that UE distributes, and comprises whole resources between UE and the cell-of-origin and the whole resources between newly assigned UE and the Target cell.This direct initiation will cause the direct call drop of UE to the processing of the release of UE, and call drop is that the user can't use UE to carry out normal talking.
As seen the processing method to UE concurrent cell update in cell switch process is very simple in the prior art, RNC directly is released to whole resources that UE distributes, though can guarantee that like this resource has obtained whole recovery, cause the certain call drop of UE, make the handover success rate of UE lower.
