Below to making the UE methods for being configured to wrong cell after above-mentioned solution cell update in the way of specific embodiment
Describe in detail.In the embodiment of the present invention, to being configured to UE after the solution cell update by taking the implementation of the 3G communication technologys as an example
The method of wrong cell is illustrated, it will be understood by those skilled in the art that for the related skill being related in other communication technologys
The UE methods for being configured to wrong cell can be equally applicable after art content, the solution cell update.
Embodiment one
UE is configured to flow such as Fig. 2 institutes of the method for wrong cell after the solution cell update of the embodiment of the present invention one
Show.
The measurement control message generation measurement report that step S10, RRC are sent according to network side is first carried out, and to wherein
Space-time validity flag is identified by the measurement report of time and spacial influence.
Because the species of the UE measurement reports generated is more, and only such as same-frequency measure reporting, different-frequency measure reporting
By time and the measurement report of spacial influence, be possible to cause because CellUpdate processes cause network side according to expired measurement
The problem of reporting and UE be configured to wrong cell, therefore, by time and spacial influence described in the step S10 of the present embodiment
Measurement report can include same-frequency measure reporting, different-frequency measure reporting, isosystem measurement report at least one of, can also
Including other by time and the measurement report of spacial influence.
In step slo, by identifying space-time validity flag to the measurement report by time and spacial influence, thus
After subsequent step, the i.e. success of CellUpdate processes and it can judge that the behavior to Signaling Radio Bearer is to reconfigure,
The expired measurement report of those in the measurement report reported is targetedly abandoned, so as to avoid network side according to expired measurement
UE is configured to wrong cell by report.
In the specific implementation, the space-time validity flag can be by the measurement report by the time and spacial influence
The form of one flag of addition is realized, if the value " 1 " of the flag in such as some measurement report, then it is assumed that the measurement report
Accuse, by the measurement report of time and spacial influence, to be otherwise other kinds of measurement report.Certainly, the space-time validity mark
Will is not limited to above-mentioned way of realization, as long as can be shown that whether some measurement report is affected due to the change in time and space
.
After step S10, step S20 is performed, when RRC will send cell update request message to network side, it is judged
In the value of information unit whether be Ture.Those skilled in the art know, cell update is included in cell update request message
The reason for, U-RNTI values, optional metrical information and with the presence or absence of the multiple information units of error reason etc., and the present invention is implemented
The information unit in cell update request message described in example refers specifically to am-RLC-ErrorIndicationRb2-3or4,
The value of the information unit is Boolean type（BOOLEAN）.
In step S20, before RRC prepares to send CellUpdate message to network side, first to CellUpdate message
In information unit am-RLC-ErrorIndicationRb2-3or4 value detected, if it find that am-RLC-
When ErrorIndicationRb2-3or4 value is Ture, then step S30 is performed, otherwise inquire whether RLC also caches and carry
The measurement report of space-time validity flag is sent to network side not successfully, that is, performs step S40.
When the value that the information unit in cell update request message is judged in step S20 is Ture, then step is performed
The cell update request message is sent to network side by S30, RRC.
When the value that the information unit in cell update request message is judged in step S20 is not Ture, that is, judge institute
When the value for stating information unit is Flase, then performs step S40, RLC and search Signaling Radio Bearer（SRB, Signal Radio
Bearer）The transmission at place is data cached to judge wherein whether also there is the measurement report with space-time validity flag, is
Step S50 is then performed, step S30 is otherwise jumped to.
Transmission described in step S40 is data cached to refer to that UE is temporarily stored into rlc layer into network side transmission data procedures and delayed
The data in area are deposited, because CellUpdate processes may be betided in data transmission procedure, therefore the transmission is data cached
The data and the data that are not sent completely for having sent but not obtained network side determination are potentially included, if UE is to network side
The data of transmission include measurement report, then measurement report may be contained in it is described send it is data cached among, and measurement report
It is also likely to be the measurement report with space-time validity flag.
In step s 40, transmissions of the RLC where by searching SRB is data cached, it can be determined that wherein with the presence or absence of with
The measurement report of space-time validity flag, is accused if it also there is the measurement report with space-time validity flag in form certainly
Know RRC, RRC is otherwise informed with negative form.
When judging measurement report of the data cached middle presence of the transmission with space-time validity flag, step is performed
The value of described information unit is set to Ture by S50, RRC.RRC made according to response acquired after step S40 it is arranged below,
Information unit am-RLC-ErrorIndicationRb2- in CellUpdate message is set if RLC response is certainly
3or4 value is True, otherwise sets information unit am-RLC-ErrorIndicationRb2-3or4 in CellUpdate message
Value be False.Information unit am-RLC-ErrorIndicationRb2-3or4 value can be forced to set by step S50
It is set to Ture, just can so advises that network side is configured to re-establish SRB, network side substantially can also receive UE transmissions
The configuration of SRB behavior is advised in CellUpdate message, is also "No" with regard to the implementing result that can make subsequent step S60, from
UE is configured according to expired measurement report without just can more efficiently solve network side by step S70 and step S80
The problem of to wrong cell.It refer to and be further described below on the behavior to SRB.
In the present embodiment, by step S20, step S40 and step S50, realize and whether be cached with space-time according to rlc layer
Validity mark measurement report and information unit am-RLC- in CellUpdate message is selectively set
ErrorIndicationRb2-3or4.In other embodiments, step S20, step S40 and step S50 can not also be included,
Detailed in Example two.
After step S50, perform step S30, RRC and the cell update request message is sent to network side.
After step S30, step S60 is performed, after cell update success, RRC informs rows of the RLC to Signaling Radio Bearer
It is then to perform step S70, otherwise the flow of this method terminates whether to be to reconfigure.
It should be noted that the cell update request message is sent to after network side by step S30, general feelings
Under condition, network side can receive to carry out the UE for sending CellUpdate message cell update, and return to cell update confirmation
（CellUpdate Confirm）Message, now CellUpdate processes successfully realize that UE receives CellUpdate
After Confirm message, UE RRC can know requirement of the network side on the behavior to SRB according to the message, described to SRB
Behavior include re-establishing SRB and reconfiguring SRB, RRC informs behaviors of the RLC to SRB, if the behavior to SRB is weight
It is new to set up, then according to relevant communication protocol, the data that UE can be discharged in original SRB, i.e. original SRB will be dropped, to net
Network side is synchronized after operation（The expired measurement report that network side is received will be dropped）, now in the absence of due to network side according to
The problem of UE is configured into wrong cell according to expired measurement report, the flow of this method terminates；If the behavior to SRB is
Reconfigure, then by prior art be that the data in SRB will not be handled, and in the embodiment of the present invention, then can hold
Row step S70 is handled some data in SRB.
Step S60 implementing result depends on configuration of the network side to SRB behavior, and the behavior to SRB is to build again
Vertical SRB still reconfigures SRB, and this aspect depends on information unit am-RLC- in CellUpdate message
ErrorIndicationRb2-3or4 value is True or False, if True, then network side would generally be configured to again
SRB is set up, if False, then would generally be configured to reconfigure SRB；On the other hand network side is also depended on according to actual money
Whether source situation can receive the configuration suggestion of the behavior to SRB in the CellUpdate message, that is to say, that in special feelings
Under condition, information unit am-RLC-ErrorIndicationRb2-3or4 value is in the CellUpdate message that UE is sent
True, network side is also possible to be configured to reconfigure SRB, now due to UE RLC cache transmission it is data cached in still deposit
In the measurement report with space-time validity flag（Expired measurement report）, the measurement that network side is expired according to these can be caused
Report and UE is configured in wrong cell, therefore the present embodiment when step S60 implementing result is "Yes", it is necessary to continue executing with
Step S70 and S80.
Perform step S70, RLC and abandon all measurement reports with space-time validity flag in the Signaling Radio Bearer
Accuse.In the specific implementation, RLC will abandon that in SRB where all measurement reports with space-time validity flag to step S70
Send data cached, it is described send it is data cached it is same include having sent but without the data for obtaining network side confirmation and
The data not being sent completely.
After step S70, perform step S80, RLC and send movably receiving window to network side（MRW, Move
Receiving Window）To notify it to abandon corresponding measurement report.In step S80, RLC to network side by sending MRW
To notify network side to abandon those expired measurement reports, so as to reach the UE purposes synchronous with network side.Due to network side
Those expired measurement reports are abandoned, then also avoid that UE is configured into wrong cell according to expired measurement report
