Wherein, said gravity treatment and/or measurement configuration parameter satisfy following condition:
Make subscriber equipment when carrying out gravity treatment according to said gravity treatment and/or measurement configuration parameter, translational speed is big more, tends to select carrier frequency low more in the optional carrier frequency more.
As shown in Figure 1; The cordless communication network in an area has the carrier frequency (800MHz that is generally used for gsm communication shown in for example scheming of a plurality of services; Be generally used for the 1800MHz of LTE communication); There is different coverages the sub-district of these two kinds of carrier frequency, and the coverage of the GSM sub-district of visible 800MHz is bigger among the figure, and the coverage of the LTE sub-district of 1800MHz is less.The size of cell coverage area is relevant with carrier frequency on the one hand: the propagation characteristic of radio magnetic wave has determined carrier frequency high more, and its covering performance is poor more, and penetration performance is poor more, and the Doppler effect when UE moves is remarkable more; On the other hand; The size of cell coverage area is also relevant with the deployment of operator; For example operator possibly be deployed as the GSM of 800MHz the network that seamless covering is provided to the user, and the LTE of 1800Mhz is deployed as the network that the service of focus high speed business is provided to the user.In addition, the size of cell coverage area is also relevant, as shown in Figure 2 with wireless access technology (RAT), and the GSM of 800MHz provides wide covering, and the LTE of 2.4GHz and the WLAN of 5GHz (or WIFI) provide focus to cover.Generally; The carrier frequency that different access technologies is used can not conflict mutually, like this, and in given area; Carrier frequency corresponding usually specific access technology and Access Network; The for example corresponding GSM of 800Mhz, GERAN, 1800Mhz and corresponding LTE of 2350Mhz and E-UTRAN, 2460MHz and 5GHz correspondence WIFI.So, in fact also the specific access technology/standard on this carrier frequency is taken into account when considering carrier frequency, in other words, specific carrier frequency implies has indicated specific standard.
Usually; Operator disposes lower carrier frequency to be covered as purpose widely; The coverage of corresponding sub-district is also bigger, and its tenability to the UE fast moving is also better, and the higher frequency of operator's deployment is a purpose with capacity or the throughput that improves hot zones usually; The coverage of corresponding sub-district is also less, and its tenability to the UE fast moving then descends.
When moving velocity of terminal is fast, be more suitable for adopting the better low frequency of covering performance to carry out mobile communication, so not only can reduce gravity treatment/switching times, and further reduce gravity treatment/handover failure rate, reduce the expense of terminal and network, also help the economize on electricity at terminal.That is to say that the translational speed at terminal should have the bonus point effect for the low carrier frequency of preferential selection, for preferential selection high carrier frequency the branch of subtracting effect is arranged in other words.For this reason, the side-play amount of the carrier frequency through the different terminal translational speed should also have difference, and translational speed is high more, and the side-play amount of low carrier frequency also should bigger (being more prone to select hang down carrier frequency) like this.As depicted in figs. 1 and 2, the UE of high-speed mobile should be more prone to select 800MHz, and the UE that low speed moves should be more prone to select 1800MHz, 2.4GHz (or 5GHz).
In addition, translational speed is high more, carrier frequency is high more, and gravity treatment or switching are carried out in the terminal to be needed in time more, and therefore, gravity treatment and measurement parameter also should change along with the variation of the translational speed of UE and carrier frequency.

Step 504, UE uses the carrier shift amount under the middling speed that alien frequencies (comprising different standard) sub-district is assessed, and finishes;
Step 505, UE uses the carrier shift amount under the low speed that alien frequencies (comprising different standard) sub-district is assessed, and finishes.
Below pass through instance 1 to instance 3 explained in detail Fig. 3 to flow process shown in Figure 5.
Instance 1
The UE that is in free time (Idle) attitude carries out place in the competition (rank) according to following formula to each sub-district after Serving cell and (same priority) alien-frequency district are measured:
Rs＝Qmeas，s+Qhyst；
Rn＝Qmeas，n-Qoffset；
Wherein, Rs and Rn are respectively the measurement parameters that is used for Serving cell and adjacent area are carried out rank, Qmeas, s and Qmeas; N is respectively the signal strength measurement of UE to Serving cell or adjacent area; Qhyst is the hypothesis factor, and Qoffset equals Qoffsets for the sub-district of alien frequencies, and n (the sub-district side-play amount of Serving cell and neighboring interval) adds Qoffset Frequency(the carrier shift amount between service carrier frequency and target carrier frequency), if there is not effective Qoffsets, the n value, then Qoffset equals Qoffset Frequency
In the above parameter, Qmeas, s and Qmeas, n are UE through Serving cell and adjacent sub-district are measured, and other parameter all is that UE receives from the system information (SIB) that send the base station.Consider the influence of the different translational speeds of UE to different carrier frequency, UE is using Qoffset FrequencyThe time use corresponding carrier shift amount according to the mobile status of self.For this reason; The base station is through the pairing carrier shift amount of the different mobile statuss of system information broadcast (for example low speed, middling speed, at a high speed); Perhaps basic side-play amount of base station broadcast; Corresponding one of this basis side-play amount is specified mobile status, under other mobile statuss, regulates according to this basis side-play amount and corresponding side-play amount regulatory factor (scaling factor) parameter.Such as; Can directly use during low speed should the basis side-play amount; And corresponding side-play amount regulatory factor when needing during to middling speed, high speed again according to the middling speed of base station broadcast and high speed, the regulatory factor of UE during corresponding carrier shift amount when obtaining middling speed, high speed respectively with basic offset addition with middling speed, high speed.Certainly, basic side-play amount also can be at a high speed corresponding, regulates according to the side-play amount regulatory factor when low speed, middling speed, and the present invention does not limit this.Carrier shift amount under the friction speed of base station configuration comes from the network management system (OAM) of base station.
The mobile status at terminal self can be passed through location (for example according to GPS localization method or base station positioning method) and obtain, and also can judge according to the number of cells of process in the certain hour to obtain, and can also obtain according to the transducer of ability perception translational speed.
UE (possibly comprise with sub-district frequently Serving cell and neighbor cell according to top method; The alien-frequency district of same priority) measure and rank after; The rank that just can determine whether neighbor cell exceeds Serving cell (can claim also that at this moment this neighbor cell is a Target cell); When this state continuance surpassed certain hour (being the gravity treatment time), UE just can gravity treatment arrive Target cell.
Through the suitable carrier shift amount that particular frequency carrier under side-play amount regulatory factor or the specific mobile status is set, UE at a high speed down with regard to more difficult gravity treatment to the higher carrier frequency of frequency, in other words, UE arrives the lower carrier frequency of frequency in easier down gravity treatment at a high speed.
For example; When service carrier frequency (being the carrier frequency of the current resident sub-district of UE) is 900Mhz; When the adjacent carrier frequency that UE measures is 1800Mhz; Having corresponding (basis) the carrier shift amount of 1800Mhz carrier frequency in the reselecting parameters information of base station broadcast is-3dB, and also has in the reselecting parameters information under at a high speed, and the side-play amount regulatory factor that the 1800Mhz carrier frequency is corresponding is 6dB.Like this, for the UE of high-speed motion, the actual carrier frequency side-play amount Qoffset of its use FrequencyBe 3dB.Like this, the low frequency carrier frequency that makes high speed UE as far as possible reside in to cover, thus reduce the district reselecting number of times, reduce expense simultaneously, and help economize on electricity.
In addition, the base station also can influence the measurement report behavior of UE under different mobility, thereby improve the travelling performance of UE through the hypothesis factor under the specific mobility of configuration, the particular frequency carrier.
Instance 2
The UE that is in connected state measures Serving cell and neighbor cell (sub-district that possibly comprise alien frequencies), and whether triggers measurement report according to the configuration determination of the measurement report event of base station configuration.
The measurement report event of base station configuration comprises the A3 incident, and the entry condition of this incident is inequality Mn+Ofn+Ocn-hys＞Mp+Ofp+Ocp+off, and the condition of leaving is inequality Mn+Ofn+Ocn+hys＜Mp+Ofp+Ocp+off.Wherein, Mn and Mp are the measured value of UE to the signal of adjacent sub-district and main Serving cell; Ofn and Ofp are the carrier shift amount of target carrier frequency (carrier frequency that use the adjacent sub-district of measurement) and main service carrier frequency; Ocn and Ocp are the sub-district side-play amount of adjacent sub-district and main Serving cell, and hys is the hypothesis factor, and off is the side-play amount of this incident.When entry condition is satisfied and its duration surpasses the triggered time (TimetoTrigger), then UE initiates measurement report.Consider of the influence of the different translational speeds of UE to different carrier frequency; UE uses corresponding carrier shift amount according to the mobile status of self when using Ofn and Ofp; For this reason; Different mobile statuss (for example low speed, middling speed, at a high speed) main down service carrier frequency and the pairing carrier shift amount of other carrier frequency are sent through measurement configuration in the base station; Comprise basic side-play amount in the measurement configuration information that perhaps send the base station to each carrier frequency; Can directly use the corresponding basic side-play amount of corresponding carrier frequency during low speed, and side-play amount regulatory factor (scaling factor) parameter of each corresponding carrier frequency when needing during to middling speed, high speed, the regulatory factor of UE during corresponding carrier shift amount when obtaining middling speed or high speed with the basic offset addition of this carrier frequency with the middling speed of certain carrier frequency or high speed again according to middling speed in the measurement configuration information and high speed.
For example; When serving carrier frequency is 900Mhz, and when the adjacent carrier frequency that UE measures was 1800Mhz, having 900MHz carrier frequency pairing (basis) carrier shift amount in the measurement configuration information that send the base station was 0dB; (basis) carrier shift amount that the 1800Mhz carrier frequency is corresponding is 6dB; And have in the measurement configuration information under at a high speed, the side-play amount regulatory factor that the 900MHz carrier frequency is corresponding is 3dB, the side-play amount regulatory factor that the 1800Mhz carrier frequency is corresponding is-4dB.The mobile status at terminal self can obtain from localization method (for example according to GPS localization method or base station positioning method), also can judge according to the number of cells of process in the certain hour to obtain, and can also obtain according to the transducer of ability perception translational speed.Like this, for the UE of high-speed motion, the actual carrier frequency side-play amount Ofn and the Ofp of its use are respectively 2dB and 3dB.Like this, UE arrives the higher carrier frequency of frequency with regard to more difficult gravity treatment under at a high speed, in other words; The lower carrier frequency of frequency is arrived in UE easier gravity treatment under at a high speed; Thereby, make high speed UE use the low frequency carrier frequency that covers as far as possible, thereby reduce switching times and handover failure rate; Reduce expense simultaneously, and help economize on electricity.
Except UE confirms the method for relevant parameters according to the mobile status of self; The base station also can be the different parameter of UE configuration according to the mobile status of UE; Like this, UE just can directly use this parameter to carry out measurement processing after receiving the parameter of base station configuration.
In addition, the base station also can influence the measurement report behavior of UE under different mobility, thereby improve the travelling performance of UE through the hypothesis factor and/or triggered time parameter under the specific mobility of configuration, the particular frequency carrier.
Instance 3
The UE that is in connected state measures Serving cell and neighbor cell (sub-district that possibly comprise alien frequencies), and whether triggers measurement report according to the configuration determination of the measurement report event of base station configuration.
Wherein, the measurement report event of base station configuration comprises A4 incident or A5 incident or B1 incident or B2 incident, and is concrete, comprising:
The entry condition that is applicable to the A4 incident of E-UTRAN sub-district is inequality Mn+Ofn+Ocn-hys＞Thresh, and the condition of leaving is inequality Mn+Ofn+Ocn+hys＜Thresh;
The entry condition that is applicable to the B1 incident of different standard sub-district is inequality Mn+Ofn-hys＞Thresh, and the condition of leaving is inequality Mn+Ofn+hys＜Thresh;
The entry condition that is applicable to the A5 incident of E-UTRAN sub-district is inequality Mp+hys＜Thresh and Mn+Ofn+Ocn-hys＞Thresh2, and the condition of leaving is inequality Mp-hys＞Thresh and Mn+Ofn+Ocn+hys＜Thresh2;
The entry condition that is applicable to the B2 incident of different standard sub-district is inequality Mp+hys＜Thresh and Mn+Ofn-hys＞Thresh2, and the condition of leaving is inequality Mp-hys＞Thresh and Mn+Ofn+hys＜Thresh2.
Wherein, Mn and Mp are the measured value of UE to the signal of adjacent sub-district and main Serving cell, and Ofn is the carrier shift amount of target carrier frequency (carrier frequency that use the adjacent sub-district of measurement); Ocn is the sub-district side-play amount of adjacent sub-district; Hys is the hypothesis factor, and Thresh, Thresh2 are the relevant threshold value of incident.
When entry condition is satisfied and its duration surpasses the triggered time (TimetoTrigger), then UE initiates measurement report.Consider of the influence of the different translational speeds of UE to different carrier frequency; UE uses corresponding carrier shift amount according to the mobile status of self when using Ofn; For this reason; Different mobile statuss (for example low speed, middling speed, at a high speed) the pairing carrier shift amount of adjacent carrier frequency is down sent through measurement configuration in the base station; Comprise basic side-play amount in the measurement configuration information that perhaps send the base station to each carrier frequency; Can directly use the corresponding basic side-play amount of corresponding carrier frequency during low speed, and side-play amount regulatory factor (scaling factor) parameter of each corresponding carrier frequency when needing during to middling speed, high speed, the regulatory factor of UE during corresponding carrier shift amount when obtaining middling speed or high speed with the basic offset addition of this carrier frequency with the middling speed of certain carrier frequency or high speed again according to middling speed in the measurement configuration information and high speed.
For example; When the service carrier frequency is 900Mhz; When the adjacent carrier frequency that UE measures is 1800Mhz; Having corresponding (basis) the carrier shift amount of 1800Mhz carrier frequency in the measurement configuration information that send the base station is 6dB, and has in the measurement configuration information under at a high speed, and the side-play amount regulatory factor that the 1800Mhz carrier frequency is corresponding is-4dB.The mobile status at terminal self can obtain from localization method (for example according to GPS localization method or base station positioning method), also can judge according to the number of cells of process in the certain hour to obtain, and can also obtain according to the transducer of ability perception translational speed.Like this, for the UE of high-speed motion, the actual carrier frequency side-play amount Ofn that it uses is 2dB.Like this, UE arrives the higher carrier frequency of frequency with regard to more difficult gravity treatment under at a high speed, in other words; The lower carrier frequency of frequency is arrived in UE easier gravity treatment under at a high speed; Thereby, make high speed UE use the low frequency carrier frequency that covers as far as possible, thereby reduce switching times and handover failure rate; Reduce expense simultaneously, and help economize on electricity.
Except UE confirms the method for relevant parameters according to the mobile status of self; The base station also can be the different parameter of UE configuration according to the mobile status of UE; Like this, UE just can directly use this parameter to carry out measurement processing after receiving the parameter of base station configuration.
In addition, the base station also can influence the measurement report behavior of UE under different mobility, thereby improve the travelling performance of UE through the hypothesis factor and/or triggered time parameter under the specific mobility of configuration, the particular frequency carrier.
Fig. 6 is second kind of particular flow sheet of the embodiment of the invention one; As shown in Figure 6, may further comprise the steps:
Step 601, UE receives the corresponding threshold information of particular frequency carrier under specific mobility that sends the base station;
Step 602, UE confirms the mobility of self, if be that then execution in step 603 at a high speed, if be middling speed, then execution in step 604, if be low speed, then execution in step 605;
Step 603, the threshold parameter of corresponding carrier frequency was assessed alien frequencies (comprising different standard) sub-district under UE used at a high speed, finished;
Step 604, UE uses the threshold parameter of corresponding carrier frequency under the middling speed that alien frequencies (comprising different standard) sub-district is assessed, and finishes;
Step 605, UE uses the threshold parameter of corresponding carrier frequency under the low speed that alien frequencies (comprising different standard) sub-district is assessed, and finishes.
Below pass through instance 4,5 explained in detail Fig. 3, Fig. 4 and flow process shown in Figure 6:
Instance 4
After the UE that is in free time (Idle) attitude measured the alien-frequency district of Serving cell and different priorities or different standard sub-district, UE judged according to following criterion:
(1) if Thresh is provided in the system information Serving, LowQ, when the E-UTRAN of high priority carrier cell, UTRAN carrier cell or WIMAX carrier cell at T ReselectionRATSatisfy S period Qual＞Thresh X, HighQ, and UE surpasses 1 second at the current service cell residence time, UE carries out E-UTRAN carrier frequency or the gravity treatment of cross-mode carrier frequency from the current carrier frequency to the high priority; GERAN, CDMA-2000 or the WIFI carrier cell of perhaps working as high priority are at T ReselectionRATSatisfy S period Rxlev＞Thresh X, HighP, and UE surpasses 1 second at the current service cell residence time, the gravity treatment of GERAN, CDMA-2000 or the WIFI carrier frequency of UE execution from the current carrier frequency to the high priority;
(2) if Thresh is not provided in the system information Serving, LowQ, then when the E-UTRAN carrier cell of high priority or different standard carrier cell at T ReselectionRATSatisfy S period RxleV＞Thresh X, HighP, and UE surpasses 1 second at the current service cell residence time, the gravity treatment of the carrier frequency of UE execution from the current carrier frequency to the high priority;
(3) if Thresh is provided in the system information Serving, LowQ, when at Treselection RATPeriod, Serving cell satisfied Squal＜Thresh Serving, LowQAnd the E-UTRAN carrier cell of low priority, UTRAN carrier cell or WIMAX carrier cell satisfy Squal＞Thresh X, LowQ, and UE surpasses 1 second at the current service cell residence time, UE carries out E-UTRAN carrier frequency or the gravity treatment of cross-mode carrier frequency from the current carrier frequency to the low priority; Perhaps work as at Treselection RATPeriod, GERAN, CDMA-2000 or the WIFI carrier cell of low priority satisfied S Rxlev＞Thresh X, HighP, and UE surpasses 1 second at the current service cell residence time, the gravity treatment of GERAN, CDMA-2000 or the WIFI carrier frequency of UE execution from the current carrier frequency to the low priority;
(4) if Thresh is not provided in the system information Serving, LowQ, then work as at Treselection RATPeriod, Serving cell satisfied Srxlev＜Thresh Serving, LowPAnd the low priority carrier cell satisfies S Rxlev＞Thresh X, LowP, and UE surpasses 1 second at the current service cell residence time, the gravity treatment of UE execution from current carrier frequency to the low priority carrier frequency;
In the parameter that above criterion is used, S RxlevBeing UE with Squal receives class value and cell selection quality value based on the cell selecting that measures of (service/target) sub-district, and other parameter all is that UE receives from the system information that send the base station, and these parameters comprise threshold parameter (Thresh Serving, LowQ, Thresh Serving, LowP, Thresh X, LowP, Thresh X, LowQ) and gravity treatment time parameter (Treselection RAT).Consider of the influence of the different translational speeds of UE to different carrier frequency/standards; UE mobile status according to self when usage threshold parameter and/or time parameter is used relevant parameters (parameter of different carrier frequency/standards comes from the network management system of base station under the friction speed of base station configuration); Like this; Different mobile statuss (for example low speed, middling speed, at a high speed) pairing threshold parameter of different systems/carrier frequency and gravity treatment time parameter are down broadcasted through system information (SIB) in the base station; Perhaps basic thresholding/gravity treatment time parameter of base station broadcast; Can directly use this parameter during low speed; And corresponding regulatory factor (scaling factor) parameter when needing during to middling speed, high speed again according to the middling speed of base station broadcast and high speed, the regulatory factor of UE during and basic thresholding/gravity treatment time parameter addition (for threshold parameter) (for the gravity treatment time parameter) corresponding threshold parameter and the gravity treatment time parameter when obtaining middling speed, high speed that perhaps multiply each other with middling speed, high speed.The mobile status at terminal self can obtain from localization method (for example according to GPS localization method or base station positioning method), also can judge according to the number of cells of process in the certain hour to obtain, and can also obtain according to the transducer of ability perception translational speed.
UE determines whether to implement the gravity treatment of neighbor cell after according to top method Serving cell and neighbor cell (alien-frequency district that possibly comprise different priorities) being measured according to the criterion of preceding text.Through suitable thresholding and/or the gravity treatment time parameter regulatory factor of being provided with, UE at a high speed down with regard to more difficult gravity treatment to the higher carrier frequency of frequency, in other words, UE arrives the lower carrier frequency of frequency in easier down gravity treatment at a high speed.
For example; When service carrier frequency (being the carrier frequency of the current resident sub-district of UE) is 1800Mhz, the low priority carrier frequency that UE measures is 900Mhz, when the high priority carrier frequency is 2.4GHz; Have 900Mhz carrier frequency corresponding (basis) thresholding and gravity treatment time in the reselecting parameters information of base station broadcast; And also have in the reselecting parameters information under at a high speed, the thresholding regulatory factor that the 900Mhz carrier frequency is corresponding is-3dB that gravity treatment time regulatory factor is 0.75.Like this, for the UE of high-speed motion, its gravity treatment is just lower and the gravity treatment time is lower to the corresponding thresholding of 900MHz carrier frequency, and so just the carrier cell of 900Mhz is arrived in gravity treatment more easily.Otherwise, for the carrier frequency of 2.4GHz, having in the reselecting parameters information of base station broadcast under at a high speed, the thresholding regulatory factor that the 2.4Ghz carrier frequency is corresponding is 2dB, gravity treatment time regulatory factor is 1.25.Like this, for the UE of high-speed motion, its gravity treatment is just higher and the gravity treatment time is longer to the corresponding thresholding of 2.4GHz carrier frequency, like this with regard to the carrier cell of more difficult gravity treatment to 2.4Ghz.Like this, the low frequency carrier frequency that makes high speed UE as far as possible reside in to cover, thus reduce the district reselecting number of times, reduce expense simultaneously, and help economize on electricity.
In addition, the base station also can influence the measurement report behavior of UE under different mobility, thereby improve the travelling performance of UE through the hypothesis factor and/or gravity treatment time parameter under the specific mobility of configuration, the particular frequency carrier.
Instance 5
The UE that is in connected state measures Serving cell and neighbor cell (sub-district that possibly comprise alien frequencies), and whether triggers measurement report according to the configuration determination of the measurement report event of base station configuration.
The measurement report event of base station configuration comprises A4 incident or A5 incident or B1 incident or B2 incident.The entry condition that is applicable to the A4 incident of E-UTRAN sub-district is inequality Mn+Ofn+Ocn-hys＞Thresh; The condition of leaving is inequality Mn+Ofn+Ocn+hys＜Thresh; The entry condition that is applicable to the B1 incident of different standard sub-district is inequality Mn+Ofn-hys＞Thresh, and the condition of leaving is inequality Mn+Ofn+hys＜Thresh.The entry condition that is applicable to the A5 incident of E-UTRAN sub-district is inequality Mp+hys＜Thresh and Mn+Ofn+Ocn-hys＞Thresh2; The condition of leaving is inequality Mp-hys＞Thresh and Mn+Ofn+Ocn+hys＜Thresh2; The entry condition that is applicable to the B2 incident of different standard sub-district is inequality Mp+hys＜Thresh and Mn+Ofn-hys＞Thresh2, and the condition of leaving is inequality Mp-hys＞Thresh and Mn+Ofn+hys＜Thresh2.Wherein, Mn and Mp are the measured value of UE to the signal of adjacent sub-district and main Serving cell, and Ofn is the carrier shift amount of target carrier frequency (carrier frequency that use the adjacent sub-district of measurement); Ocn is the sub-district side-play amount of adjacent sub-district; Hys is the hypothesis factor, Thresh, and Thresh2 is the relevant threshold value of certain incident.When entry condition is satisfied and its duration surpasses the triggered time (TimetoTrigger), then UE initiates measurement report.Consider of the influence of the different translational speeds of UE to different carrier frequency; UE uses corresponding threshold parameter according to self mobile status, target carrier frequency when using Thresh or Thresh2; For this reason; Different mobile statuss (for example low speed, middling speed, at a high speed) the pairing threshold parameter of adjacent carrier frequency is down sent through measurement configuration in the base station; Comprise basic threshold parameter in the measurement configuration information that perhaps send the base station to each carrier frequency; Can directly use the corresponding basic threshold parameter of corresponding carrier frequency during low speed, and thresholding regulatory factor (scaling factor) parameter of each corresponding carrier frequency when needing during to middling speed, high speed, the thresholding regulatory factor of UE during corresponding threshold parameter when obtaining middling speed or high speed with the basic thresholding addition of this carrier frequency with the middling speed of certain carrier frequency or high speed again according to middling speed in the measurement configuration information and high speed.For example; When the service carrier frequency is 900Mhz; When the adjacent carrier frequency that UE measures was 1800Mhz, the indication incident was the A4 incident in the measurement configuration information that send the base station, and to have corresponding (basis) thresholding of 1800Mhz carrier frequency be 0dB; And have in the measurement configuration information under at a high speed, the thresholding regulatory factor that the 1800Mhz carrier frequency is corresponding is 3dB.Like this, for the UE of high-speed motion, its actual thresholding Thresh that uses is 3dB.The mobile status at terminal self can obtain from localization method (for example according to GPS localization method or base station positioning method), also can judge according to the number of cells of process in the certain hour to obtain, and can also obtain according to the transducer of ability perception translational speed.Like this, UE arrives the higher carrier frequency of frequency with regard to more difficult gravity treatment under at a high speed, thereby, make high speed UE use the low frequency carrier frequency that covers as far as possible, thereby reduce switching times and handover failure rate, reduce expense simultaneously, and help economize on electricity.
Except UE confirms the method for relevant parameters according to the mobile status of self; The base station also can be the different parameter of UE configuration according to the mobile status of UE; Like this, UE just can directly use this parameter to carry out measurement processing after receiving the parameter of base station configuration.
In addition, the base station also can influence the measurement report behavior of UE under different mobility, thereby improve the travelling performance of UE through the hypothesis factor and/or triggered time parameter under the specific mobility of configuration, the particular frequency carrier.
Fig. 7 is the third particular flow sheet of the embodiment of the invention one; As shown in Figure 7, may further comprise the steps:
Step 701, UE receives the particular frequency carrier corresponding priorities information under specific mobility that send the base station;
Step 702, UE confirms the mobility of self, if be that then execution in step 703 at a high speed, if be middling speed, then execution in step 704, if be low speed, then execution in step 705;
Step 703, the priority parameters of corresponding carrier frequency was assessed alien frequencies (comprising different standard) sub-district under UE used at a high speed, finished;
Step 704, UE uses the priority parameters of corresponding carrier frequency under the middling speed that alien frequencies (comprising different standard) sub-district is assessed, and finishes;
Step 705, UE uses the priority parameters of corresponding carrier frequency under the low speed that alien frequencies (comprising different standard) sub-district is assessed, and finishes.
Below pass through instance 6 explained in detail Fig. 3, Fig. 4 and flow process shown in Figure 7:
Instance 6
After the UE that is in free time (Idle) attitude measured Serving cell and alien-frequency district (containing different standard sub-district), UE was usually according to carrying out reselection evaluation/judgement like the criterion in the instance 4.Of instance 4, UE needs to use the priority parameters of different frequency/different standard when carrying out whether carrying out gravity treatment to different frequency/different standard sub-district.Consider of the influence of the different translational speeds of UE to different carrier frequency; UE mobile status, target carrier frequency according to self when carrying out reselection evaluation used the corresponding priority level parameter; For this reason; Different mobile statuss (for example low speed, middling speed, at a high speed) the pairing priority parameters of adjacent carrier frequency/standard is down sent through system information in the base station; Comprise basic priority parameters in the system information that perhaps send the base station to each carrier frequency; Can directly use the corresponding basic priority parameters of corresponding carrier frequency during low speed; And priority regulatory factor (scaling factor) parameter of each corresponding carrier frequency when needing during to middling speed, high speed again according to middling speed in the system information and high speed, corresponding priorities parameter when the basic priority addition of priority regulatory factor and this carrier frequency of UE during with the middling speed of certain carrier frequency or high speed obtains middling speed or high speed.
For example; When serving carrier frequency is 900Mhz, and when the adjacent carrier frequency that UE measures was 1800Mhz, the priority of indication 900MHz was 4 in the system information that send the base station; The priority of 1800Mhz is 5; And indication is under at a high speed, and the priority regulatory factor of 900MHz is+1, and 1800Mhz carrier frequency corresponding priorities regulatory factor is-1.Like this, for the UE of high-speed motion, the priority of 1800Mhz is lower than the priority of 900Mhz.Like this, UE just need satisfy more condition from the 900MHz gravity treatment to 1800Mhz, and the signal that promptly is not only required in gravity treatment time internal object sub-district is enough good, and requires in the gravity treatment time the good inadequately (Squal＜Thresh of the signal of Serving cell Serving, LowQPerhaps Srxlev＜Thresh Serving, LowP).Like this, through priority that reduces high carrier frequency under the high speed and/or the priority that promotes low carrier frequency, UE arrives the higher carrier frequency of frequency with regard to more difficult gravity treatment under at a high speed; Perhaps the lower carrier frequency of frequency is arrived in gravity treatment more easily; Thereby, make high speed UE use the low frequency carrier frequency that covers as far as possible, thereby reduce the gravity treatment number of times; Reduce expense simultaneously, and help economize on electricity.
Embodiment two
Fig. 8 is the basic flow sheet of the embodiment of the invention two.As shown in Figure 8, may further comprise the steps:
Step 801, UE is provided with to specific mobility, the gravity treatment of particular frequency carrier or measurement parameter;
Step 802, UE is according to its mobility, the processing that gravity treatment that current service carrier frequency and/or (gravity treatment or measurement) target carrier frequency are corresponding or measurement parameter carry out gravity treatment or measurement.
Below through instance 7 explained in detail flow process shown in Figure 8.
Instance 7
After the UE that is in free time (Idle) attitude measured Serving cell and alien-frequency district (containing different standard sub-district), UE can be according to carrying out reselection evaluation/judgement like the criterion in the instance 4.Of instance 4, UE needs to use the priority parameters of different frequency/different standard when carrying out whether carrying out gravity treatment to different frequency/different standard sub-district.Consider of the influence of the different translational speeds of UE to different carrier frequency; UE mobile status, target carrier frequency according to self when carrying out reselection evaluation used the corresponding priority level parameter; For this reason; The pre-configured different mobile statuss of UE (for example low speed, middling speed, at a high speed) are the pairing priority parameters of adjacent carrier frequency/standard down; Perhaps comprise basic priority parameters in UE pre-configured to each carrier frequency; Can directly use the corresponding basic priority parameters of corresponding carrier frequency during low speed, and priority regulatory factor (scaling factor) parameter of each corresponding carrier frequency when needing during to middling speed, high speed, the priority regulatory factor of UE during corresponding threshold parameter when obtaining middling speed or high speed with the basic priority addition of this carrier frequency with the middling speed of certain carrier frequency or high speed again according to middling speed in pre-configured and high speed.For example; When serving carrier frequency is 900Mhz, and when the adjacent carrier frequency that UE measures was 1800Mhz, the priority of indication 900MHz was 4 in the system information that send the base station; The priority of 1800Mhz is 5; And indication is under at a high speed, and the priority regulatory factor of 900MHz is+1, and 1800Mhz carrier frequency corresponding priorities regulatory factor is-1.The mobile status at terminal self can obtain from localization method (for example according to GPS localization method or base station positioning method), also can judge according to the number of cells of process in the certain hour to obtain, and can also obtain according to the transducer of ability perception translational speed.Like this, for the UE of high-speed motion, the priority of 1800Mhz is lower than the priority of 900Mhz.Like this, UE just need satisfy more condition from the 900MHz gravity treatment to 1800Mhz, and the signal that promptly is not only required in gravity treatment time internal object sub-district is enough good, and requires in the gravity treatment time the good inadequately (Squal＜Thresh of the signal of Serving cell Serving, LowQPerhaps Srxlev＜Thresh Serving, LowP).Like this, through priority that reduces high carrier frequency and/or the priority that promotes low carrier frequency, UE arrives the higher carrier frequency of frequency with regard to more difficult gravity treatment under at a high speed; Perhaps the lower carrier frequency of frequency is arrived in gravity treatment more easily; Thereby, make high speed UE use the low frequency carrier frequency that covers as far as possible, thereby reduce the gravity treatment number of times; Reduce expense simultaneously, and help economize on electricity.
Be that to have illustrated UE be the method that different carrier frequency are provided with different priorities according to different translational speeds to example above with priority; In addition; UE can also be that different carrier frequency are provided with different carrier shift amount parameters according to different translational speeds; Threshold parameter, is supposed factor parameter at gravity treatment time/triggered time parameter.Concrete grammar is similar to the method among the embodiment one, and difference is that UE is not provided with these parameters through the base station, but sets these parameters through pre-configured method.Repeat no more at this.
