Background technology
Extensive commercial wireless access technology (RadioAccessTechnologies at present, RAT) global system for mobile communications (GlobalSystemforMobileCommunication can be comprised, GSM), the code division multiple access skill technology (TimeDivision-SynchronousCodeDivisionMultipleAccess of time division synchronous, TDSCDMA), universal mobile telecommunications system (UniversalMobileTelecommunicationsSystem, UMTS), Wideband Code Division Multiple Access (WCDMA) (WidebandCodeDivisionMultipleAccess, and Long Term Evolution (LongTermEvolution WCDMA), LTE) etc.Different RAT can comprise different frequencies, and frequency is the numbering to fixed frequency.During wireless coverage division of cells by different frequent points, the coverage of subscriber equipment (UserEquipment, UE) in community is undertaken by this community and network alternately.
Ambulant UE, UE can be moved in different minizones.In order to make UE obtain better service in the process of movement, need to make UE constantly serve better community from a cell merge to another.UE is cell reselection from a cell merge to the process of another community.When UE moves in the minizone that different RAT covers, UE will carry out gravity treatment between different RAT.Because the standard of LTE is set up, third generation partner program (3rdGenerationPartnershipProject, 3GPP) set of specifications introduces a kind of reselection criterion: based on the reselection criterion of priority, specifically by priority different for the cell allocation under each RAT, the cell preference gravity treatment that priority is high, the community not distributing priority can not by gravity treatment.So, if network is not to the corresponding precedence information of cell configuration of a certain RAT or frequency, even if so the signal strength signal intensity of this community is very strong, the non-constant of signal of Serving cell, UE also cannot reselect to the strong community of signal, causes Consumer's Experience poor.
Summary of the invention
The embodiment of the present invention provides a kind of residence reselecting and subscriber equipment, can solve UE and cannot reselect to the problem that network does not have the RAT of configuration preference level information or the community of frequency.
First aspect, provides a kind of residence reselecting, comprising:
When user equipment (UE) need carry out cell reselection, described UE determines the frequency whether configuration preference level information of the adjacent area of described UE current service cell;
If determine no, then described UE carries out cell reselection according to the precedence information of the frequency configured in described UE or according to the signal strength signal intensity of described adjacent area.
Like this, for the adjacent area not having configuration preference level information, if current service cell signal difference, then can carry out cell reselection according to the precedence information of the frequency configured in UE or according to the signal strength signal intensity of described adjacent area, make UE can reselect to the strong adjacent area of signal, to promote Consumer's Experience.
In a kind of possible design, described UE determines whether configuration preference level information comprises for the frequency of the adjacent area of described UE current service cell:
Described UE determines whether Neighboring Cell List that described UE receives comprises precedence information, the frequency that described Neighboring Cell List comprises the adjacent area of Serving cell described in wireless access technology RAT and the precedence information configured of the frequency of described adjacent area.Wherein, some frequency in Neighboring Cell List may not have configuration preference level information.Determine whether configuration preference level information can make UE still carry out cell reselection according to the default priority configured in UE for the frequency of adjacent area by UE, promote the service quality of UE.
In a kind of possible design, the precedence information configured in described UE comprises the default priority information of the frequency of non-configuration preference level information in Long Term Evolution LTE, and the default priority information of the frequency of non-configuration preference level information in the universal terrestrial access network UTRAN of evolution;
The default priority information of described LTE comprises the default priority of the frequency of non-configuration preference level information in described LTE, minimum reference signal received power (ReferenceSignalReceivingPower, RSRP) the reception value of described LTE small area selection and the minimum RSRP reception value of described LTE small area gravity treatment;
The default priority information of described UTRAN comprises the default priority of the frequency of non-configuration preference level information in described UTRAN, minimum received signal code power (ReceivedSignalCodePower, RSCP) the reception value of described UTRAN small area selection and the minimum RSCP reception value of described UTRAN small area gravity treatment;

Thus, when there is precedence information in the frequency that the adjacent area of the Serving cell of UE is corresponding, cell reselection can be carried out according to the priority of the frequency specified in 3GPP, if when there is not precedence information in frequency corresponding to the adjacent area of the Serving cell of UE, cell reselection can be carried out according to the default priority of the frequency of non-configuration preference level information in the default priority of the frequency of configuration preference level information non-in LTE and UTRAN, can reselect in the adjacent area of 3G or the adjacent area of 4G to make UE, be unlikely to cannot carry out cell reselection and cause lost network or difference in signal strength when making frequency corresponding to the adjacent area of the Serving cell of UE there is not precedence information.
In a kind of possible design, described UE is according to the precedence information of the frequency configured in described UE or carry out cell reselection according to the signal strength signal intensity of described adjacent area and comprise:
Described UE determines whether described UE supports 4G standard, and namely the 4G switch of UE is in opening or closed condition;
If determine, described UE does not support described 4G standard, then described UE reselects to the maximum adjacent area of signal strength signal intensity according to the signal strength signal intensity of adjacent area in described UTRAN;
If determine, described UE supports described 4G standard, then described UE carries out cell reselection according to the default priority information of the described LTE configured in described UE and the default priority information of described UTRAN.
Thus, when UE does not support 4G standard, UE also can be made from the cell reselection of 2G to the large adjacent area of the signal strength signal intensity of 3G; During UE support 4G standard, make UE from the adjacent area of the adjacent area or 3G that can reselect to 4G, improve Consumer's Experience.
In a kind of possible design, described UE carries out cell reselection according to the default priority information of the described LTE configured in described UE and the default priority information of described UTRAN and comprises:
Described UE determines whether the signal strength values of the adjacent area that the frequency of non-configuration preference level information in described LTE is corresponding is greater than the minimum RSRP reception value of described LTE small area gravity treatment;
That then described UE reselects to community corresponding to the frequency of non-configuration preference level information in described LTE if determine;
If determine no, then described UE reselects to community corresponding to the frequency of non-configuration preference level information in described UTRAN.
Thus, when UE supports 4G standard, can preferentially attempt reselecting in the adjacent area of 4G, but if the poor signal quality of the adjacent area of LTE, just reselect in the adjacent area of 3G, to promote the service quality of UE.
Second aspect, provides a kind of subscriber equipment, comprising:

The embodiment of the present invention provides a kind of residence reselecting, as shown in Figure 2, comprising:
201, when user equipment (UE) need carry out cell reselection, UE determines the frequency whether configuration preference level information of the adjacent area of UE current service cell.
When UE resides in the Serving cell of arbitrary frequency, the Neighboring Cell List that base station controller is sent by system message can be received, the frequency that this Neighboring Cell List comprises the adjacent area of UE current service cell and the precedence information configured.Wherein, may be configured with corresponding precedence information by part frequency in the frequency in Neighboring Cell List, the part frequency yet likely existed under RAT or this RAT is not configured precedence information.Precedence information is for characterizing the community of different frequent points for priority during cell reselection, and the data transmission capabilities of the community that the frequency that priority is large is corresponding and data transmission bauds are higher than community corresponding to the low frequency of priority.Wherein, same frequency can corresponding multiple community, a corresponding frequency in community.
Exemplary, when UE to reside in Serving cell be 2G and RAT be community corresponding to a certain frequency of GSM time, UE can receive the Neighboring Cell List that base station controller sends, this Neighboring Cell List comprises the frequency that frequency that 3G and RAT is the adjacent area of UMTS and 4G and RAT are the adjacent area of LTE, wherein part frequency is configured with precedence information, and likely part frequency is not configured with priority yet.If when the current difference in signal strength of UE needs to carry out cell reselection, the community reselected to is determined in meeting according to the precedence information of this Neighboring Cell List intermediate-frequeney point, but because the frequency of part 3G or 4G may not be configured with priority, so UE just cannot reselect to the community of 3G or 4G, therefore, UE first can determine when carrying out cell reselection whether the frequency of adjacent area is configured with precedence information.
If the frequency in the Neighboring Cell List of UE current service cell is all configured with precedence information, so cell reselection can be carried out according to the cell re-selection mechanism in 3GPP specification.Each frequency has independent priority, and its priority can inform UE by system information, and also can know to UE by wireless heterogeneous networks (RadioResourceControl, RRC) message, operator can be configured priority.By arranging to the priority of the frequency of current service cell and the frequency of adjacent area the priority height can distinguishing each frequency in system information or RRC information.Such as priority can be 0,1,2,3 ..., 0 to represent priority minimum.If the priority of the frequency of adjacent area is greater than the priority of the frequency of current service cell, then UE needs to reselect to adjacent area.Wherein, the gravity treatment of community also needs the signal quality simultaneously with reference to current service cell and target re-selecting cell, namely when determining the high target re-selecting cell of priority, the signal quality of target re-selecting cell is also higher than threshold value, this threshold value is also carried in the precedence information of frequency, if current service cell quality is worse than threshold value and residence time exceedes lag time, then to perform the reselection operation of this target re-selecting cell.
If the frequency of the adjacent area of UE current service cell is not configured precedence information, then can carry out cell reselection according to the precedence information of UE internal configurations.
Wherein, the precedence information configured in UE comprises the default priority information of the frequency of non-configuration preference level information in Long Term Evolution LTE, and the default priority information of the frequency of non-configuration preference level information in the universal terrestrial access network UTRAN of evolution.
The default priority information of LTE comprises the minimum RSRP reception value of the default priority of the frequency of non-configuration preference level information in LTE, minimum reference signal received power RSRP reception value that LTE small area is selected and the gravity treatment of LTE small area.
Exemplary, the default priority information of LTE can be:
E-UTRAN_PRIORITY:-1
THRESH_E-UTRAN_High＝THRESH_E-UTRAN_Low：-120dBm
E-UTRAN_QRXLEVMIN：-128dBm
Wherein, E-UTRAN_PRIORITY represents in LET the priority of the frequency not being configured precedence information, and its priority value is-1, lower than the lowest priority 0 of 3GPP regulation and stipulation;
THRESH_E-UTRAN_High represents UE from the cell reselection of 2G to the minimum reference signal received power RSRP reception value that LTE adjacent area during the adjacent area that the frequency of high priority 4G is corresponding need meet; RSRP reception value characterizes the signal strength signal intensity of community.
The RSRP reception value that when THRESH_E-UTRAN_Low represents that UE reselects to adjacent area corresponding to the frequency of low priority 4G from 2G, LTE adjacent area need meet;
E-UTRAN_QRXLEVMIN represent that community selects time minimum RSRP reception value.Such as, when the community that the frequency that confirmation priority is high is corresponding, can first according to community select time minimum RSRP reception value determine the community being greater than-128dBm, then determine that the community of-120dBm that the signal strength signal intensity of community is greater than THRESH_E-UTRAN_Low or THRESH_E-UTRAN_High instruction is target re-selecting cell.
The default priority information of UTRAN comprises the minimum RSRP reception value of the default priority of the frequency of non-configuration preference level information in UTRAN, minimum RSRP reception value that UTRAN small area is selected and the gravity treatment of UTRAN small area;
Exemplary, the default priority information not being configured the frequency of precedence information in UTRAN can be set to:
UTRAN_PRIORITY:-2
THRESH_UTRAN_High＝THRESH_UTRAN_Low:-105dBm
UTRAN_QRXLEVMIN:-110dBm
Wherein, UTRAN_PRIORITY represents in UTRAN the priority of the frequency not being configured precedence information, and its priority value is-2, lower than the priority-1 of frequency not being configured priority in LTE;
THRESH_UTRAN_High represents the minimum reference signal received power RSCP reception value that UE need meet from UTRAN adjacent area during the cell reselection of 2G paramount priority 3 G adjacent area;
The RSCP reception value that when THRESH_UTRAN_Low represents UE from the cell reselection of 2G to low priority 3G adjacent area, UTRAN adjacent area need meet;
UTRAN_QRXLEVMIN represent that community selects time minimum RSCP reception value.Such as, when the community that the frequency that confirmation priority is high is corresponding, can first according to community select time minimum RSCP reception value determine the community being greater than-110dBm, then determine that the community of-105dBm that the signal strength signal intensity of community is greater than THRESH_UTRAN_Low or THRESH_UTRAN_High instruction is target re-selecting cell.
Wherein, in LTE, the default priority of the frequency of non-configuration preference level information is lower than the priority of the frequency specified in third generation partner program 3GPP, and in UTRAN, the default priority of the frequency of non-configuration preference level information is lower than the default priority of the frequency of configuration preference level information non-in LTE.
When determining that the frequency of adjacent area is not configured precedence information, owing to being configured with default priority, just can reselect to this adjacent area according to default priority when the priority of the adjacent area of UE is greater than the priority of current service cell, to promote the service quality of UE.Suppose in the community of the current a certain frequency residing in 2G of UE, if UE does not support the frequency of LTE, so UE just cannot from the cell reselection of 2G to the community of 4G, but the community of 3G can be reselected to, therefore, first can determine when the frequency of the adjacent area determining UE is not configured priority whether UE supports 4G data service.Therefore, the method also comprises:
202, UE determines whether UE supports 4G standard, if determine is, then perform step 204, if determine no, then performs step 203.
Whether UE supports that 4G standard can be in opening by the 4G switch in UE or closed condition is determined.If UE closes 4G switch, then illustrate that UE does not support 4G standard; If determine that UE supports 4G standard, namely the 4G switch of UE is in opening.
203, UE reselects to the maximum adjacent area of signal strength signal intensity according to the signal strength signal intensity of adjacent area in UTRAN.
Exemplary, if UE closes 4G switch, then illustrate that UE does not support 4G standard, at this moment, if in the Neighboring Cell List that UE receives UE current service cell adjacent area in, be only configured with the precedence information of the frequency under LET, and do not configure the precedence information of the frequency under UTRAN, so UE can measure the signal strength signal intensity of community corresponding to frequency under UTRAN, and determines that the maximum community of neighboring area signal intensity is target re-selecting cell.If the precedence information of the frequency under being configured with UTRAN, reselection criterion when not introducing according to 4G, UE also needs to measure the signal strength signal intensity of community corresponding to frequency under UTRAN, and determines that the maximum community of neighboring area signal intensity is target re-selecting cell.
204, UE carries out cell reselection according to the default priority information of the LTE configured in UE and the default priority information of UTRAN.
If determine that UE supports 4G standard, namely the 4G switch of UE is in opening, at this moment, the priority of the frequency under UTRAN is greater than according to the priority of the frequency under the default priority information of LTE and the known LTE of default priority information of UTRAN, first can measure the signal strength signal intensity of community corresponding to frequency under LTE, obtain signal strength values, if the signal strength values of the community that the frequency under LTE is corresponding is greater than the-120dBm in LTE default priority information, and the signal strength values of community corresponding to frequency under the LTE measured is greater than-120dBm continue for preset time period, the signal of the community that the frequency so under explanation LTE is corresponding is better, the community that frequency under UE re eligible to LTE is corresponding,
If the signal strength values of the community that the frequency under LTE is corresponding is less than-120dBm, the poor signal quality of the community that frequency under LTE is corresponding is described, in the community that the frequency so under UE re eligible to UTRAN is corresponding.Particularly, the minimum RSCP reception value can selected according to the default priority information small area of UTRAN determines that signal strength values is greater than the set of cells of-110dBm, then, from this set of cells, determine that community that signal strength values is greater than-105dBm is the target re-selecting cell of UE again, like this, the priority of the frequency when network configuration under LTE, but when not configuring the priority of the frequency under UTRAN, if the signal difference of UE current service cell, when but the signal of the community that the frequency under LTE is corresponding is also poor, in the community that the frequency that UE can be reselected under 3G by the default priority information of UTRAN is corresponding, to promote the service quality of UE.
The embodiment of the present invention provides a kind of residence reselecting, and when UE need carry out cell reselection, described UE determines the frequency whether configuration preference level information of the adjacent area of described UE current service cell; If determine no, then described UE carries out cell reselection according to the precedence information of the frequency configured in described UE or according to the signal strength signal intensity of described adjacent area, like this, for the adjacent area not having configuration preference level information, if current service cell signal difference, then can carry out cell reselection according to the precedence information of the frequency configured in UE or according to the signal strength signal intensity of described adjacent area, make UE can reselect to the strong adjacent area of signal, to promote Consumer's Experience.
