101st, the signal quality of neighbor cell is measured.

102nd, according to the cell speed information of neighbor cell and the obtained signal quality information of measurement, selection signal satisfactory quality and meet user equipment (UE) translational speed cell.

Wherein, due to UE translational speed it is higher in the case of may be quickly moved in a short time The covering edge of serving cell, or the coverage of serving cell is left, now, the problem of can produce frequent switching or handoff failure if UE initiates connection.Therefore in order to avoid UE initiates connection failure after connection in high-speed mobile, the suitable persistent district of coverage can be selected according to UE speed.For example, the wider macrocell of coverage can be selected for the UE of high-speed mobile, the less Microcell of coverage can be then selected for the UE not moved or translational speed is relatively low.

In the present embodiment, UE is in idle condition, is resident in the serving cells, in order to adapt to UE translational speed, in the case where signal quality meets requirement, UE can select disclosure satisfy that the cell of rate request according to translational speed, it is resident in the cell, i.e. gravity treatment（Reselect) cell.So as to, it is to avoid it is resident in the less cell of coverage and causes to initiate to need frequent switching when connecting, the problem of even resulting in handoff failure.

It should be noted that cell speed information can be configured by network side and be handed down to UE or the corresponding cell speed information of the cell for each type of making an appointment difference.Cell speed information can be a velocity interval, either speed class or speed threshold etc..

The signal quality, which meets the requirements, refers to that the signal quality of neighbor cell meets the resident minimum thresholds of U E.It can further include and be higher than serving cell or the signal quality less than the certain thresholding of serving cell.

The cell selecting method that the embodiment of the present application is provided, the signal quality information obtained according to the cell speed information of neighbor cell and measurement, selection signal satisfactory quality and meet UE translational speed cell, set the UE translational speeds that different types of cell is met by, can be according to the cell that UE translational speed is the requirement of UE selectors sum velocity, hand off signaling is excessive when avoiding UE translational speed higher and being moved to the edge of persistent district in a short time or remove initiation connection behind persistent district, reduce UE load, reduce the risk of handoff failure.Another embodiment of the application provides a kind of cell selecting method, as shown in Fig. 2 can include：201st, the cell speed information that network side is issued is received.

It should be noted that the cell speed information includes following at least one：Velocity interval corresponding with cell type, speed class or speed threshold, speed model corresponding with cell scrambling location Enclose, speed class or speed threshold, velocity interval corresponding with cell list, speed class or speed threshold.Cell speed information can be sent to by broadcast or for the specific messages of downloading speed information

UE。

Wherein, network side can include cell speed information in the cell reselection parameters issued.Specifically, network side can issue the corresponding suitable velocity interval of various cell types, speed class or speed threshold.A kind of method is that network side can also issue the cell type of neighbor cell, including macrocell, Microcell, picocell etc..So, UE just can determine the suitable velocity interval in neighbor cell according to the cell type of neighbor cell, and by determining that UE itself translational speed determines whether to be adapted to be resident in the cell.Another method is, network side can not also issue explicit cell type and indicate, UE can judge the suitable velocity interval in neighbor cell according to other cell informations, for example, can determine its corresponding velocity interval according to the scrambler location of neighbor cell.Wherein speed threshold can be the maximum speed value for being adapted to UE.

In the present embodiment, step 201 is optional step, can not also perform step 201, and the corresponding suitable velocity interval of different districts type, speed class or speed threshold are arranged and configure respectively in UE and network side.So, network side only issues cell type instruction, and UE just can determine its velocity interval being adapted to according to the cell type of neighbor cell.Similarly, the suitable velocity interval of cell can also be determined according to cell scrambling.

Or, cell speed information can also be based on cell list, such as one group cell list correspondence, one velocity interval, speed class or speed threshold.At least one cell can be included in one group of cell list, the corresponding velocity interval in single subdistrict can be configured, the corresponding velocity interval of cell list of multiple cell compositions can also be configured.

Further, UE can start the flow for determining UE translational speeds under certain trigger condition, and the method for the present embodiment can also comprise the following steps 202:

202nd, UE meets speed and determines condition and/or receive the speed determination instruction that network side is issued.Wherein, meet speed and determine that condition can be：The cell type of UE serving cells belongs to the cell type that toggle speed determines flow, or the scrambler location of UE serving cells belongs to the scrambler scope that toggle speed determines flow.For example, because macrocell coverage area is larger, UE can be without Consider high-speed mobile the problem of, then can not toggle speed determine flow；And picocell coverage area is smaller, there is high-speed mobile in UE, and just leave the risk of Microcell when initiating connection, therefore meet speed and determine condition, when UE is linked into Microcell can toggle speed determine flow.

Wherein, meet speed and determine that condition can also be：Into particular type or specific scramble codes cell and after continuing for some time, restart speed and determine flow.Or, meet speed and determine that condition can also be：UE perceives signal intensity more than after certain amplitude within a certain period of time, restarts speed and determines flow.

Or, the speed that can also issue network side determines the trigger condition for indicating to determine flow as startup UE speed.For example, determine the broadcast message of flow for toggle speed when what UE received that network side issues, or receive the toggle speed that is used for that network side issues and determine that the signaling of flow is indicated, then flow can be determined with toggle speed, step 203 is performed.

203rd, the translational speed of user equipment (UE) is determined.

Wherein, UE can determine translational speed by positioning function and clocking capability or by special speed measuring function, directly can also determine translational speed information according to the translational speed information stored.For example, UE obtains UE translational speed by other applications before step 203, then the translational speed information stored can be directly read in step 203.Further, it can also judge whether the translational speed information stored has ageing, if the last time gap current time for obtaining translational speed is more long, UE translational speed can be redefined.

It is appreciated that, the translational speed or gravity treatment speed of user equipment (UE) can be determined after step 202, UE translational speed or gravity treatment speed can also be determined on other suitable opportunitys, can before the step 204, can also be after step 204.Similarly, the cell speed information in step 201 can be before measurement neighbor cell, can also be after measurement neighbor cell.For example, UE translational speed can first be determined, the predefined quality threshold of serving cell and the cell speed information of neighbor cell are obtained, in the signal quality of serving cell predefined quality threshold corresponding less than current translational speed, the measurement operation of triggering step 204.Or, triggering it can also be measured when entering Microcell, then UE translational speed is determined, then the cell speed information of neighbor cell is obtained, selection disclosure satisfy that the cell of UE translational speed from signal quality satisfactory neighbor cell. 204th, triggering measurement.

Triggering the method for measurement can be：When translational speed cell speed corresponding more than serving cell, triggering measurement.

Wherein, UE as described in step 201 can be pre-configured with or be obtained from network side the cell speed information of serving cell, cell speed is not that the disposal ability of cell base station is determined, and be due to cell footprint size it is different, the suitable UE velocity intervals of the cell of decision or speed threshold, speed class etc..For example, when UE translational speed exceeds the velocity interval, or during higher than speed threshold or beyond speed class, illustrate that UE can leave the risk of serving cell coverage under current translational speed, therefore measurement can be triggered, selects the higher cell of the wider cell speed of coverage in time for UE.

Further, the method for triggering measurement can also be：Obtain the gravity treatment speed of the UE；When the gravity treatment speed of UE gravity treatment speed corresponding more than serving cell, triggering measurement.So, UE can be when any one in translational speed and gravity treatment speed exceedes preset range, and triggering measurement improves the stability of UE services.Wherein, the gravity treatment speed is the number of times of UE gravity treatments in certain time.

Further alternative, the method for triggering measurement can also be：When the signal quality of serving cell predefined quality threshold corresponding less than the translational speed, triggering measurement.Wherein, the predefined quality threshold of serving cell can select corresponding quality threshold for the different quality threshold of different translational speeds correspondence, UE according to actual translational speed.It is that high speed UE sets higher thresholding, UE can determine the quality threshold that should be used according to current translational speed for example, setting relatively low thresholding for low speed UE.It is understood that the parameter that predefined quality threshold can be issued, make an appointment and/or voluntarily configured for network.It is understood that be between the method for above-mentioned triggering measurement " and/or " relation.I.e. in actual applications, the combination of one or more of the condition of above-mentioned triggering measurement can be selected.For example, when meeting one of trigger condition, measurement can be triggered；Or, when meeting plurality of condition simultaneously, triggering measurement.

Further, UE measurements are reduced in order to appropriate, reduces UE power consumptions, the condition setting for triggering measurement can be obtained more strict.For example, when the translational speed exceedes the corresponding cell of serving cell Speed, and continue after certain time length, trigger the measurement.When UE can trigger the measurement in serving cell signal quality predefined quality threshold corresponding less than UE translational speeds after triggering measurement, and lasting certain time length.When the cell for entering particular type or specific scramble codes, triggering measurement.When UE enters the cell of particular type or specific scramble codes, and continue after certain time length, trigger the measurement.It is understood that the parameter that the certain time length can be issued, make an appointment and/or voluntarily configured for network side.

205th, the signal quality information obtained according to the cell speed information of neighbor cell and measurement, selection signal satisfactory quality and the cell for meeting the translational speed.

Wherein, selection signal satisfactory quality and meet the method for cell of translational speed of user equipment (UE) and can include：The signal quality information that measurement is obtained is compared with nominal-mass thresholding, determines the satisfactory neighbor cell of signal quality；UE translational speed cell speed information corresponding with the satisfactory neighbor cell of the signal quality is compared, determines that signal quality meets the requirements and met the cell of the translational speed of user equipment (UE)；In the cell for choosing the translational speed that the signal quality meets the requirements and met user equipment (UE).

It is of course also possible to the neighbor cell of UE translational speeds is first determined for compliance with, then selection signal quality is higher than the cell of nominal-mass thresholding from the neighbor cell for meeting translational speed.Determine the satisfactory neighbor cell of signal quality and determine to meet the cell of UE translational speed, both sequencing present invention are not limited.
