For " being cut automatically when the measurement result of the corresponding measurement object of measurement configuration of automatic switchover is met in step 104
When the measurement changed configures corresponding measurement report condition, the user equipment switches to Target cell ", the embodiment of the present invention is provided
Following two feasible implementations.
The first feasible implementation is applied to mixing automatic switchover scene, that is, user equipment needs to send out to base station
Send measurement report and start automatic switchover timer, second of feasible implementation is applied to fully automated handoff scenario,
It is exactly that user equipment can send measurement report to base station, but does not start automatic switchover timer and receive switching command.
The implementation feasible to the first is illustrated below.
Fig. 2 is refer to, its user equipment provided by the embodiment of the present invention switches to a kind of method of Target cell
Schematic flow sheet, as shown in Fig. 2 this method includes：
201st, user equipment configures message according to measurement, it is determined that the measurement object corresponding to the measurement configuration automatically switched,
And the measurement object is measured, obtain measurement result.
202nd, when the measurement that the measurement result of the corresponding measurement object of measurement configuration of automatic switchover meets automatic switchover is matched somebody with somebody
When putting corresponding measurement report condition, user equipment starts automatic switchover timer and sent to the base station for automatically switching
Measurement report.
In a kind of concrete implementation scheme, measurement configuration message in carry above-mentioned measurement configuration, measurement object and
Measurement report condition, user equipment can be according to the measurement object carried in measurement configuration message, the target to needing measurement, i.e.,
The cell or frequency included in measurement object corresponding to the measurement configuration of automatic switchover is measured.For automatic switchover
Measurement configuration, when the measurement result of the corresponding measurement object of measurement configuration of automatic switchover meets the measurement configuration pair automatically switched
During the measurement report condition answered, user equipment is in addition to needing to send the measurement report for automatically switching, in addition it is also necessary to start
Automatic switchover timer.
When the measurement result of the corresponding measurement object of measurement configuration of automatic switchover meets the measurement configuration pair automatically switched
During the measurement report condition answered, user equipment starts automatic switchover timer and sends the survey for automatically switching to the base station
Amount report can have following three kinds of feasible implementations.
If the first, user equipment get measurement configuration message in be used for store measurement configuration field include from
Dynamic switching mark, user equipment determine this be used for store measurement configuration the measurement configuration that is stored of field be automatic switchover survey
Amount configuration, the measurement result obtained after user equipment is measured to the corresponding measurement object of measurement configuration meets the measurement
When configuring corresponding measurement report condition, user equipment starts automatic switchover timer, and is sent to base station for measurement report
Measurement report is carried in message, the measurement report message, the measurement report includes the mark for the measurement configuration automatically switched.
For example, matching somebody with somebody for storing measurement comprising the mark that automatically switches in the field set to 0, measurement, which is matched somebody with somebody, sets to 0 correspondence measurement report
Condition 3 and measurement object 1, if user equipment meets measurement report condition 3, user equipment to the measurement result of measurement object 1
Start automatic switchover timer, and the measurement report message of the measurement report to base station transmission carrying measurement object 1, the measurement report
Accuse and carry measurement with the mark set to 0.
If the field for the second, being used to store measurement object in the measurement configuration message that user equipment is got is included certainly
Dynamic switching mark, user equipment determines this for storing the survey that the measurement object that the field of measurement object is stored is automatic switchover
Object is measured, the corresponding all measurement configurations of the measurement object are all the measurement configurations automatically switched, when user equipment is to the measurement
When the measurement result that object is obtained after measuring meets the measurement object corresponding measurement report condition, user equipment start from
Dynamic switching timer, and send to be directed in measurement report message, the measurement report message to base station and carry measurement report, the measurement
Report includes the mark for the corresponding measurement configuration of measurement object for being the automatic switchover.
It should be noted that a measurement object can correspond to one or more measurement report condition, work as measurement object
Measurement result when meeting the corresponding measurement report condition of the measurement object, can just be sent to base station and correspond to measurement report condition
Measurement report message.And for the ungratified measurement report condition of measurement result of the measurement object, user equipment will not be to
Base station send to should measurement report condition measurement report message.Moreover, a measurement object can correspond to one or many
Individual measurement configuration, therefore the measurement report carried in measurement report message meets measurement report bar comprising the measurement object is corresponding
The mark of the measurement configuration of part.
For example, including the mark, the corresponding measurement report of measurement object 3 of automatically switching in field for storing measurement object 3
Condition 1 and measurement, which are matched somebody with somebody, to be set to 0, the also corresponding measurement report condition 2 of measurement object 3 and measurement configuration 1.If user equipment is to measurement pair
Measurement result as 3 meets measurement report condition 1 and is unsatisfactory for measurement report condition 2, then user equipment starts to automatically switch and determined
When device, and send to base station the measurement report message for the measurement report for carrying measurement object 3, the content of the measurement report only has survey
Amount is with the mark set to 0.Or, if user equipment meets measurement report condition 1 to the measurement result of measurement object 3 and meets measurement
Reporting conditions 2, then user equipment starts automatic switchover timer, and the measurement report for carrying measurement object 3 is sent to base station
Measurement report message, the measurement report is comprising measurement with the mark set to 0 and the mark of measurement configuration 1.
If the third, be used to store the field bag of measurement report condition in the measurement configuration message that gets of user equipment
Containing the mark that automatically switches, user equipment determines that this is for storing the measurement report condition that the field of measurement report condition is stored
The measurement report condition of automatic switchover, the corresponding all measurement configurations of the measurement report condition are all that the measurement automatically switched is matched somebody with somebody
Put, obtained after user equipment is measured to the corresponding one or more measurement objects of the measurement report condition of automatic switchover
Measurement result, when meeting the measurement report condition, user equipment starts automatic switchover timer, and is sent to base station for measurement
Measurement report is carried in report message, the measurement report message, the measurement report is corresponding one comprising the measurement report condition
Or the mark of multiple measurement configurations.
It should be noted that a measurement report condition can correspond to one or more measurement objects, when certain measurement report
When the measurement result of the corresponding measurement object of condition meets the measurement report condition, it can just be sent to base station and correspond to the measurement report
The measurement report message of announcement condition.And for the ungratified measurement report condition of measurement result of measurement object, user equipment is not
Can to base station send to should measurement report condition measurement report message.Moreover, a measurement object can correspond to one or
The multiple measurement configurations of person, therefore the content of the measurement report carried in measurement report message is that the measurement report condition is satisfied
When, the mark of measurement configuration corresponding with the measurement report condition being satisfied.
For example, including the mark, the correspondence of measurement report condition 3 of automatically switching in field for storing measurement report condition 3
Measurement object 1 and measurement are with setting to 0, and measurement report condition 3 also corresponds to measurement object 2 and measurement configuration 1.If user equipment is to measurement
The measurement result of object 1 meets measurement report condition 3, and the measurement result of measurement object 2 is unsatisfactory for measurement report condition 3, then
User equipment starts automatic switchover timer, and the measurement report message of the measurement report to base station transmission carrying measurement object 0,
The content of the measurement report only has measurement with the mark set to 0.Or, if user equipment is met to the measurement result of measurement object 1
Measurement report condition 3, and the measurement result of measurement object 2 also meets measurement report condition 3, then user equipment, which starts, automatically switches
Timer, and send the measurement report message for carrying measurement report to base station, the measurement report comprising measurement with the mark that sets to 0 and
The mark of measurement configuration 1.
If the 4th kind, be used to store the field bag of measurement report condition in the measurement configuration message that receives of user equipment
Containing the mark that automatically switches, and the field for being used for storing measurement object in configuration message is measured also comprising the mark that automatically switches, use
Family determines that the measurement report condition and the measurement configuration corresponding to the measurement object are the measurement configurations automatically switched.As user couple
When the measurement result of the measurement object meets the measurement report condition, user equipment starts automatic switchover timer, and to base station
Send to be directed in measurement report message, the measurement report message and carry measurement report, the measurement report includes the measurement report bar
The mark of measurement configuration corresponding to part and the measurement object.
203rd, measurement report of the base station according to being sent the user equipment for automatic switchover, it is determined that switching is described
User equipment, and send handover preparation request to target BS.
Specifically, base station obtains the measurement report message that user equipment is sent, it is directed to if being carried in the measurement report message
The measurement report of automatic switchover, then base station determination needs to switch the user equipment, it is therefore desirable to initiates switching and prepares, Ke Yixiang
Target BS sends handover preparation request.Wherein, base station can be according to the cell carried in the measurement report for automatic switchover
Mark, it is determined that switching the Target cell of the user equipment, and then sends switching standard to the target BS where the Target cell
Standby request.
In a kind of concrete implementation scheme, user can be carried in the handover preparation request that base station is sent to target BS
The contextual information of equipment.
In a kind of feasible implementation, base station can be sent by X2 interface or S1 interfaces to target BS to be switched
Preparation request.
In the present embodiment, base station judges whether the measurement report message that user equipment is sent carries the survey for automatically switching
Amount report has following several feasible implementations.
The first, measurement configuration message in be used for store measurement configuration field comprising automatically switch mark situation
Under, if the measurement configuration corresponding to the mark of the measurement configuration carried in the measurement report message that base station is got, belongs to and includes
The field for the mark that automatically switches stores measurement configuration, then base station determines the measurement report of the measurement configuration in measurement report message
Announcement is the measurement report for automatically switching.
Secondth, it is used to store the situation that the field of measurement object includes the mark that automatically switches in measurement configuration message
Under, if the measurement object corresponding to the mark of the measurement configuration carried in the measurement report message that base station is got, belongs to and includes
The field for the mark that automatically switches stores measurement object, then base station determines the measurement of the measurement configuration in the measurement report message
Report is the measurement report for automatically switching.
For example, comprising measurement with the mark set to 0 in measurement report message, the mark correspondence measurement object 1 set to 0 is matched somebody with somebody in the measurement
With measurement report condition 3, it is used for if measurement is configured in message in the field for storing measurement object 1 comprising the mark that automatically switches,
It is the measurement report for automatically switching to represent that the measurement report set to 0 is matched somebody with somebody in the measurement.
The third, be used in measurement configuration message to store the feelings that the field of measurement report condition includes the mark that automatically switches
Under condition, if the measurement report condition corresponding to the mark of the measurement configuration carried in the measurement report message that base station is got, category
Measurement report condition is stored in the field comprising the mark that automatically switches, then base station determines the measurement in the measurement report message
The measurement report of configuration is the measurement report for automatically switching.
For example, comprising measurement with the mark set to 0 in measurement report message, the mark correspondence measurement object 1 set to 0 is matched somebody with somebody in the measurement
With measurement report condition 3, it is used for if measurement is configured in message in the field for storing measurement report condition 3 comprising the mark that automatically switches
Know, then it represents that it is the measurement report for automatically switching that the measurement report set to 0 is matched somebody with somebody in the measurement.
4th kind, be used in measurement configuration message storing the field of measurement report condition comprising automatically switching mark simultaneously
In the case of storing the field of measurement object comprising the mark that automatically switches, if being taken in the measurement report message that base station is received
Measurement report condition corresponding to the mark of the measurement configuration of band belongs to the field comprising the mark that automatically switches and stores measurement report
Announcement condition, and corresponding measurement object belongs to the measurement object that the field comprising the mark that automatically switches is stored, then and base station is true
The measurement report of measurement configuration in the fixed measurement report message is the measurement report for automatically switching.
For example, comprising measurement with the mark set to 0 in measurement report message, the mark correspondence measurement object 1 set to 0 is matched somebody with somebody in the measurement
With measurement report condition 3, it is used for if measurement is configured in message in the field for storing measurement report condition 3 comprising the mark that automatically switches
And include the mark that automatically switches in the field for storing measurement object 1, then it represents that it is pin that the measurement report set to 0 is matched somebody with somebody in the measurement
To the measurement report of automatic switchover.
In a kind of optional implementation, base station is sent to target BS before handover preparation request, and base station can be with
Cell list or station list are sent to user equipment.Included wherein in cell list each in one or more target BS
The mark of one or more cells under target BS, station list can include each target in one or more target BS
The mark of base station.Cell list or station list are used for user equipment in selection target cell, preferentially from cell list
Cell in selection target cell, or the preferential cell selection target cell under the base station in station list.
204th, when the base station gets the response message for the handover preparation request that the target BS is sent, to described
User equipment sends switching command.
Specifically, target BS is after the handover preparation request of base station transmission is got, according to the user equipment of its carrying
Contextual information, determine whether the user equipment access.
If allowing the user equipment to access, target BS sends the response message of handover preparation request to base station, wherein
Carrying allows switching command.So, base station can get the response message of the handover preparation request of target BS transmission, and root
According to the permission switching command of its carrying, switching command is sent to user equipment, the switching command is used to indicate what can be switched to
Target cell.But, based on LBT mechanism, when base station needs to send switching command to user equipment, first monitor channel whether by
Take, if listened to, channel is occupied, and base station can not send switching command to user equipment, so as to cause to cut automatically
Changing timer, then user equipment does not receive switching command also.If listening to channel idle, base station can smoothly be sent
