Fig. 3 A is referred to, it illustrates the method flow diagram of another Gap selection method provided in an embodiment of the present invention, UE measures Gap SL Gap according to the relative priority selection measurement between measurement Gap and SL Gap in the present embodiment.The Gap selection method may include:

Step 301, base station is determined as the measurement Gap of UE configuration.

When this method is applied to long term evolution (English: long term evolution；Abbreviation LTE) in system when, base station is specifically eNB (eNodeB)；When this method is applied to Universal Mobile Communication System (English: (universal mobile telecommunications system；When referred to as: UMTS), base station is specifically NB (NodeB)；When this method is applied to Wireless Fidelity (English: Wireless Fidelity；English: WiFi) in when, base station be specifically access point (English: access point；Referred to as: AP).

A usual UE includes a transceiver, and a transceiver synchronization can only on a frequency point receiving and transmitting signal, therefore, when the adjacent cell of the serving cell of UE and serving cell alien frequencies, base station needs to configure measurement Gap for UE, so that UE is interrupted in measurement Gap and the communication of base station, nearby region measurement is carried out；It is measuring in the time except Gap, UE is kept and the communication of base station, without nearby region measurement.

In the present embodiment, base station can be the time that UE configuration measurement Gap occurs according to factors, wherein the time that measurement Gap occurs by start time, measure the appearances period of Gap and measure the lasting duration of Gap and determine.Wherein, start time can be what base station directly issued, be also possible to after base station issues offset, UE is calculated according to offset, and this embodiment is not limited.

The present embodiment is illustrated so that the quantity for the alien frequencies that base station measures as needed is the appearance period of UE configuration measurement Gap as an example.Specifically, the appearance period assignment of Gap will be measured smaller when alien frequencies quantity is more；It is the appearance period assignment of Gap will be measured larger when alien frequencies negligible amounts.

When the lasting duration of each measurement Gap of configuration, in one possible implementation, the lasting duration of each measurement Gap is configured when configuration measures Gap by base station；In alternatively possible implementation, the lasting duration of each measurement Gap is determined by UE.

Wherein, when determining the lasting duration of each measurement Gap by UE, UE can read the duration that each measurement Gap is lasting specified in communication protocol；Alternatively, UE can determine the lasting duration of each measurement Gap with itself.When UE itself determines the lasting duration of each measurement Gap, the lasting duration of each measurement Gap can be notified base station by UE, can not also notify base station, this embodiment is not limited.

Step 302, base station generates configuration information, which is used to indicate the time that measurement Gap occurs.

Step 303, base station sends configuration information to UE.

Step 304, UE receives the configuration information that base station is sent.

Step 305, the time that UE occurs according to the measurement Gap time occurred and SL Gap, judge to measure whether Gap conflicts with SL Gap, the time which occurs is configured according to predetermined policy.

Wherein, the time that SL Gap occurs is determined by start time, the appearance period of SL Gap and the lasting duration of SL Gap.

In the present embodiment, the configuration for the time that SL Gap occurs can be what base station issued, is also possible to UE decision, both implementations are introduced separately below:

When the configuration in the appearance period of SL Gap is issued by base station, base station can be the appearance period that UE configures SL Gap according to factors, for example, the appearance period that base station is UE configuration SL Gap according to available resources, so that guaranteeing that there are available resources transmits data packet in SL Gap for UE.Wherein, UE transmits data packet in SL Gap and can specifically include: UE is by SL Gap received data packet on SL, alternatively, UE sends data packet by SL Gap on SL.

It should be noted that in a kind of possible mode, base station is that each SL Gap configuration the period occurs when configuring the appearance period of SL Gap, for example, the appearance period of each SL Gap is 40ms, there is a SL Gap every 40ms at this time；In alternatively possible implementation, base station is grouped using the SL Gap of predetermined number as one, the appearance period of configuration SL Gap grouping, such as, it is grouped 3 SL Gap as one, and the appearance period of each SL Gap grouping is 40ms, a SL Gap grouping occurs every 40ms at this time.

When the lasting duration of configuration SL Gap, in one possible implementation, by base station in duration configuration SL Gap lasting when there is the period for configuring SL Gap；In alternatively possible implementation, the lasting duration of SL Gap is determined by UE.Wherein, when determining the lasting duration of SL Gap by UE, UE can read the duration that SL Gap is lasting specified in communication protocol；Alternatively, UE can determine the lasting duration of SL Gap with itself.When UE itself determines the lasting duration of SL Gap, SL Gap lasting duration can be notified base station by UE, can not also notify base station, this embodiment is not limited.

It should be noted that in a kind of possible mode, base station is that each SL Gap configures duration, for example, each SL Gap lasting duration is 10ms in the lasting duration of configuration SL Gap；In alternatively possible implementation, base station is grouped using the SL Gap of predetermined number as one, it configures SL Gap and is grouped lasting duration, such as, it is grouped 3 SL Gap as one, and each SL Gap a length of 100ms when being grouped lasting, configuring 3 durations in the duration of 100ms at this time is 10ms SL Gap.For example, configuration SL Gap occurs in 10ms, 30ms and 50ms, alternatively, configuration SL Gap occurs in 20ms, 60ms and 80ms, this embodiment is not limited.

The information for being used to indicate the time of SL Gap appearance can also be added to together in the configuration information in step 302 by base station, send the signaling that both information are wasted to save base station by additional configuration information.

When the configuration in the appearance period of SL Gap is determined by UE, UE can read the appearance period of SL Gap specified in communication protocol；Alternatively, UE can determine the appearance period of SL Gap with itself.When UE itself determines the appearance period of SL Gap, the appearance periodic notification base station of SL Gap can not also be notified base station, this embodiment is not limited by UE.Wherein, UE itself determines that the process in the appearance period of SL Gap is identical as the base station configuration appearance process in period of SL Gap, does not repeat herein.

UE is also it needs to be determined that SL Gap lasting duration configures the lasting duration of SL Gap by base station in one possible implementation；In alternatively possible implementation, by UE at the appearance period for determining SL Gap, the lasting duration of SL Gap is determined.Wherein, when determining the lasting duration of SL Gap by UE, UE can read the duration that SL Gap is lasting specified in communication protocol；Alternatively, UE can determine the lasting duration of SL Gap with itself.When UE itself determines the lasting duration of SL Gap, SL Gap lasting duration can be notified base station by UE, can not also notify base station, this embodiment is not limited.

Whether no matter the configuration of SL Gap is determined by base station configuration or UE, can all clash without the concern for measurement Gap and SL Gap, to reduce the requirement of configuration measurement Gap and SL Gap, improve the efficiency of configuration Gap.Wherein, measurement Gap and SL Gap, which is clashed, refers to the time that measurement Gap occurs and the time conflict that SL Gap occurs.Please refer to the schematic diagram that Gap and SL Gap is measured shown in Fig. 3 B, wherein third SL Gap conflicts with second measurement Gap, and the 4th SL Gap conflicts with third measurement Gap.

After measurement Gap and SL Gap has been determined, UE carries out timing, nearby region measurement is carried out within the time that measurement Gap occurs, in SL transmitting data packet within the time that SL Gap occurs.Since measurement Gap and SL Gap may conflict, and UE can only select one from measurement Gap and SL Gap in synchronization, therefore, UE carries out nearby region measurement or by SL Gap before SL transmitting data packet in measurement Gap, it is also necessary to judge to measure whether Gap conflicts with SL Gap.

Specifically, according to the time that the measurement Gap time occurred and SL Gap occur, judge to measure whether Gap conflicts with SL Gap, comprising:

1) corresponding to the next measurement Gap determined after current time according to the measurement Gap time occurred Period, and the period of next SL Gap after current time is determined according to the time that SL Gap occurs, judge whether the period corresponding to measurement Gap is be overlapped with the period of SL Gap, the minimum value of period corresponding to measurement Gap be to measure the period of Gap, and period that the maximum value for measuring the period corresponding to Gap be measurement Gap and UE are from measuring the sum of period needed for Gap is switched to SL Gap；Alternatively,

2) period corresponding to the next SL Gap determined after current time according to the SL Gap time occurred, and the period of next measurement Gap after current time is determined according to the time that measurement Gap occurs, judge whether period corresponding to SL Gap and the period for measuring Gap are be overlapped, the minimum value of period corresponding to SL Gap is the period of SL Gap, period that the maximum value of period corresponding to SL Gap is SL Gap and UE from SL Gap be switched to measurement Gap needed for the sum of period.

When occurring that a measurement Gap after current time, the first duration is positioned backward at the beginning of based on measurement Gap obtained for the first moment, whether will appear a SL Gap in period determined by detection start time and the first moment, when will appear a SL Gap in the period, measurement Gap and SL Gap conflict is determined；When in the period being not in a SL Gap, determine that measurement Gap and SL Gap will not conflict, the minimum value of first duration is to measure the lasting duration of Gap, maximum value is to measure the lasting duration of Gap plus the obtained duration of the first scheduled duration, the first scheduled duration be UE from measurement Gap be switched to SL Gap needed for duration.In actual implementation, the first scheduled duration can be set to 0.5ms, may be set to be other numerical value, this embodiment is not limited.Alternatively,

When occurring that a SL Gap after current time, the second duration is positioned at the beginning of based on SL Gap backward and obtained for the second moment, whether will appear a measurement Gap in period determined by detection start time and the second moment, when will appear a measurement Gap in the period, the SL Gap and measurement Gap conflict is determined；When in the period being not in a measurement Gap, determine that the SL Gap and measurement Gap will not conflict, the minimum value of second duration is the lasting duration of SL Gap, maximum value is the lasting duration of SL Gap plus the obtained duration of the second scheduled duration, the second scheduled duration be UE from SL Gap be switched to measurement Gap needed for duration.In actual implementation, the second scheduled duration can be set to 0.5ms, may be set to be other numerical value, and the second scheduled duration and the first scheduled duration are identical or different, this embodiment is not limited.

Step 306, when measurement Gap conflicts with SL Gap, UE obtains the relative priority between measurement Gap and SL Gap, and the relative priority between measurement Gap and SL Gap is that base station issues, alternatively, the relative priority between measurement Gap and SL Gap is that UE is determined.

In one possible implementation, by the relative priority between sending measuring Gap and the SL Gap of base station；In alternatively possible implementation, the phase between measurement Gap and SL Gap is determined by UE To priority.Wherein, when determining the relative priority between measurement Gap and SL Gap by UE, UE can read the relative priority between measurement Gap and SL Gap specified in communication protocol；Alternatively, UE can determine the relative priority between measurement Gap and SL Gap with itself.When UE itself determines to measure the relative priority between Gap and SL Gap, UE can will measure the relative priority between Gap and SL Gap and notify base station, can not also notify base station, this embodiment is not limited.

When by relative priority between sending measuring Gap and the SL Gap of base station, method provided in this embodiment, further include: base station sends the relative priority between measurement Gap and SL Gap to UE, and the relative priority between measurement Gap and SL Gap is used to indicate UE selection measurement Gap SL Gap.

Specifically, that base station and UE appoint that base station issues is the Gap of the high priority or Gap of low priority, and hereafter, base station only needs clearly measure the relative priority between Gap and SL Gap to UE sending measuring Gap or SL Gap, UE.For example, base station and UE appoint that base station issues is the Gap of high priority, then as base station sending measuring Gap, UE determines that measurement Gap relative to SL Gap is high priority；When base station issues SL Gap, UE determine SL Gap relative to measurement Gap be high priority.Alternatively, base station is respectively the numerical value for measuring Gap and SL Gap configuration preference level, UE compares the two numerical value to determine the relative priority between measurement Gap and SL Gap.The present embodiment is illustrated so that the smaller priority of numerical value is higher, it is assumed that base station is that measure the numerical value of priority of Gap configuration be 2, be the numerical value of the priority of SL Gap configuration is 3, then UE can determine that measurement Gap relative to SL Gap is high priority.Certainly, the relative priority that base station can also by other means between sending measuring Gap and SL Gap, this embodiment is not limited.

Optionally, relative priority between measurement Gap and SL Gap can be added in the configuration information in step 302 by base station is sent to UE, sends the signaling that the relative priority between measurement Gap and SL Gap is wasted to save base station by additional configuration information.

Step 307, when measuring Gap compared to SL Gap is high priority, UE selection measurement Gap executes step 308.

When measuring Gap compared to SL Gap is high priority, show that the importance for carrying out nearby region measurement is higher than the importance in SL transmitting data packet, the measurement of UE selection at this time Gap.

Step 308, UE carries out nearby region measurement in measurement Gap, terminates process.

Step 309, when measuring Gap compared to SL Gap is low priority, UE selects SL Gap.

When measuring Gap compared to SL Gap is low priority, show that the importance for carrying out nearby region measurement is lower than the importance in SL transmitting data packet, UE selects SL Gap at this time.

Step 310, UE transmits data packet in SL Gap.

In addition, by according to the relative priority selection measurement Gap or SL Gap between measurement Gap and SL Gap, it can be when measuring Gap relative to SL Gap be high priority, selection measurement Gap；When measuring Gap relative to SL Gap is low priority, SL Gap is selected, so that the Gap of UE selection meets actual demand, improves the accuracy of Gap selection.

Fig. 4 is referred to, it illustrates the method flow diagram of another Gap selection method provided in an embodiment of the present invention, UE selects measurement Gap SL Gap according to the signal parameter of the serving cell of UE in the present embodiment.The Gap selection method may include:

Step 401, base station is determined as the measurement Gap of UE configuration.

Step 402, base station generates configuration information, which is used to indicate the time that measurement Gap occurs.

Step 403, base station sends configuration information to UE.

Step 404, UE receives the configuration information that base station is sent.

Step 405, the time that UE occurs according to the measurement Gap time occurred and SL Gap, judge to measure whether Gap conflicts with SL Gap, the time which occurs is configured according to predetermined policy.

Wherein, the realization process of step 401-405 is detailed in the description in step 301-305, does not repeat herein.

Step 406, when measurement Gap conflicts with SL Gap, UE obtains the signal parameter of the serving cell of UE, which is signal strength or signal quality.

In the present embodiment, signal parameter is that signal strength or signal quality can be made an appointment by base station and UE.Wherein, signal strength and signal quality are used to indicate the quality of the signal of serving cell.UE obtains signal strength or the technology of signal quality is highly developed, and the present embodiment does not repeat.

Step 407, UE comparison signal parameter and signal threshold value, which is that base station issues, alternatively, the signal threshold value is that UE is determined.

Wherein, signal threshold value is related to the signal parameter that UE is obtained.For example, signal threshold value is signal strength threshold value when the UE signal parameter obtained is signal strength；When the signal parameter that UE is obtained is When signal quality, signal threshold value is signal quality threshold value.

In one possible implementation, signal threshold value is issued by base station；In alternatively possible implementation, signal threshold value is determined by UE.Wherein, when determining signal threshold value by UE, UE can read signal threshold value specified in communication protocol；Alternatively, UE can determine signal threshold value with itself.When UE itself determines signal threshold value, signal threshold value can be notified base station by UE, can not also notify base station, this embodiment is not limited.

When issuing signal threshold value by base station, method provided in this embodiment, further includes: base station sends signal threshold value to UE, which is used to indicate UE selection measurement Gap SL Gap.

Optionally, signal threshold value can be added in the configuration information in step 402 by base station is sent to UE, sends the signaling that signal threshold value is wasted to save base station by additional configuration information.

It should be added that, UE can also obtain the signal strength and signal quality of serving cell simultaneously, signal threshold value at this time includes signal strength threshold value and signal quality threshold value, UE is needed by signal strength compared with signal strength threshold value, and by signal quality compared with signal quality threshold value.In one possible implementation, when signal strength is greater than signal strength threshold value or signal quality is greater than signal quality threshold value, determine that signal parameter is greater than signal threshold value；When signal strength is less than signal strength threshold value and signal quality is less than signal quality threshold value, determine that signal parameter is less than signal threshold value.In alternatively possible implementation, when signal strength is greater than signal strength threshold value and signal quality is greater than signal quality threshold value, determine that signal parameter is greater than signal threshold value；When signal strength is less than signal strength threshold value or signal quality is less than signal quality threshold value, determine that signal parameter is less than signal threshold value.

Step 408, when signal parameter is less than signal threshold value, UE selection measurement Gap executes step 409.

When signal parameter is less than signal threshold value, show that serving cell signal at this time is poor, UE preferentially carries out nearby region measurement, so that adjacent cell be switched to the serving cell of UE when the signal of adjacent cell is preferable, in time to guarantee the normal communication of UE.

Step 409, UE carries out nearby region measurement in measurement Gap, terminates process.

Step 410, when signal parameter is greater than signal threshold value, UE selects SL Gap.

When signal parameter is greater than signal threshold value, show that serving cell signal at this time is preferable, UE need not preferentially carry out nearby region measurement.

Step 411, UE transmits data packet in SL Gap.

In conclusion Gap selection method provided in an embodiment of the present invention, by selecting one from measurement Gap and SL Gap when measurement Gap conflicts with SL Gap；When selection be measurement Gap when, measuring Nearby region measurement is carried out in Gap；Or, when selection be SL Gap when, data packet is transmitted in SL Gap, so that UE still can carry out nearby region measurement in measurement Gap or transmit data packet in SL Gap, it is not necessary to measurement Gap and the SL Gap that configuration is staggered completely each other when measurement Gap and SL Gap conflict, to solve measurement Gap and the SL Gap that configuration is staggered completely each other, cause the difficulty for configuring Gap big, the low problem of allocative efficiency has achieved the effect that the efficiency for improving configuration Gap.

In addition, Gap SL Gap is measured by the signal parameter selection of the serving cell according to UE, it can be in the dtr signal of serving cell, selection measurement Gap, preferentially to carry out nearby region measurement, and when the signal of adjacent cell is preferable, adjacent cell is switched to the serving cell of UE, in time to guarantee the normal communication of UE.

Fig. 5 is referred to, it illustrates the method flow diagram of another Gap selection method provided in an embodiment of the present invention, UE selects measurement measurement Gap SL Gap according to the priority of data packet in the present embodiment.The Gap selection method may include:

Step 501, base station is determined as the measurement Gap of UE configuration.

Step 502, base station generates configuration information, which is used to indicate the time that measurement Gap occurs.

Step 503, base station sends configuration information to UE.

Step 504, UE receives the configuration information that base station is sent.

Step 505, the time that UE occurs according to the measurement Gap time occurred and SL Gap, judge to measure whether Gap conflicts with SL Gap, the time which occurs is configured according to predetermined policy.

Wherein, the realization process of step 501-505 is detailed in the description in step 301-305, does not repeat herein.

Step 506, when measurement Gap conflicts with SL Gap, UE obtains the priority of data packet.

Data packet refers to the data packet that will be transmitted on SL by SL Gap.The priority of data packet can be embodied by numerical value, for example, the numerical value of the priority of data packet is 1, or, the numerical value of the priority of data packet is 4 etc., this embodiment is not limited.Wherein, the technology of the priority of UE acquisition data packet is highly developed, and the present embodiment does not repeat.

Step 507, UE compares the priority and packet priority threshold value of data packet, and packet priority threshold value is that base station issues, alternatively, packet priority threshold value is that UE is determined.

In one possible implementation, packet priority threshold value is issued by base station；In alternatively possible implementation, by UE determination data packet priority threshold value.Wherein, when by UE determination data packet priority threshold value, UE can read packet priority threshold value specified in communication protocol；Alternatively, UE can be with itself determination data packet priority threshold value.When UE itself determination data packet priority door When limit value, packet priority threshold value can be notified base station by UE, can not also notify base station, this embodiment is not limited.

When issuing packet priority threshold value by base station, method provided in this embodiment, further includes: base station sends packet priority threshold value to UE, which is used to indicate UE selection measurement Gap SL Gap.

Optionally, packet priority threshold value can be added in the configuration information in step 502 by base station is sent to UE, sends the signaling that packet priority threshold value is wasted to save base station by additional configuration information.

Assuming that the smaller priority of numerical value is higher, and the numerical value of the priority of data packet is 2, and packet priority threshold value is 3, then the priority of data packet is higher than packet priority threshold value；Assuming that packet priority threshold value is 1, then the priority of data packet is lower than packet priority threshold value.

Step 508, when the priority of data packet is lower than packet priority threshold value, UE selection measurement Gap executes step 509.

When the priority of data packet is lower than packet priority threshold value, demonstrating the need for the data packet transmitted on SL not is that very promptly, UE preferentially selects measurement Gap.

Step 509, UE carries out nearby region measurement in measurement Gap, terminates process.

Step 510, when the priority of data packet is higher than packet priority threshold value, UE selects SL Gap.

When the priority of data packet is higher than packet priority threshold value, the data packet for demonstrating the need for transmitting on SL is very urgent, and UE preferentially selects SL Gap.

Step 511, UE transmits data packet in SL Gap.

In addition, by selecting measurement measurement Gap SL Gap according to the priority of data packet, it can be when the priority of data packet be higher than packet priority threshold value, the data packet that determination will be transmitted on SL by SL Gap is very urgent, SL Gap is selected, preferentially at this time to guarantee being normally carried out for business.

Fig. 6 is referred to, it illustrates the method flow diagram of another Gap selection method provided in an embodiment of the present invention, whether UE belongs to public safety (English: Public Safety according to data packet in the present embodiment；Referred to as: PS) service selection measurement measurement Gap SL Gap.The Gap selection method may include:

Step 601, base station is determined as the measurement Gap of UE configuration.

Step 602, base station generates configuration information, which is used to indicate the time that measurement Gap occurs.

Step 603, base station sends configuration information to UE.

Step 604, UE receives the configuration information that base station is sent.

Step 605, the time that UE occurs according to the measurement Gap time occurred and SL Gap, judge to measure whether Gap conflicts with SL Gap, the time which occurs is configured according to predetermined policy.

Wherein, the realization process of step 601-605 is detailed in the description in step 301-305, does not repeat herein.

Step 606, when measurement Gap conflicts with SL Gap, UE determines whether data packet belongs to PS business.

Wherein, PS business refers to the business of public safety.For example, PS business includes military communication service；Non- PS business includes civilian or commercial communication service.

When determining whether data packet belongs to PS business, in one possible implementation, UE determines whether data packet belongs to PS business according to the attribute of itself, for example, all data packets of UE transmission belong to PS business when UE is military intercom.In alternatively possible implementation, UE determines whether data packet belongs to PS business according to the attribute of data packet, for example, UE reads the purpose IP address (English: Internet Protocol of the data packet；Referred to as: IP) and destination port, detect whether the purpose IP address and destination port are destination IP used in PS business and destination port, when destination IP used in the purpose IP address and destination port are PS business and destination port, determine that the data packet belongs to PS business；When destination IP used in the purpose IP address and destination port are not PS business and destination port, determine that the data packet is not belonging to PS business.Certainly, UE can also determine whether data packet belongs to PS business by other means, and this embodiment is not limited.

Step 607, when data packet is not belonging to PS business, UE selection measurement Gap executes step 608.

When data packet is not belonging to PS business, demonstrating the need for the data packet transmitted on SL not is that very promptly, UE preferentially selects measurement Gap.

Step 608, UE carries out nearby region measurement in measurement Gap, terminates process.

Step 609, when data packet belongs to PS business, UE selects SL Gap.

When data packet belongs to PS business, the data packet for demonstrating the need for transmitting on SL is very urgent, and UE preferentially selects SL Gap.

Step 610, UE transmits data packet in SL Gap.

In conclusion Gap selection method provided in an embodiment of the present invention, by selecting one from measurement Gap and SL Gap when measurement Gap conflicts with SL Gap；When selection be measurement Gap when, measurement Gap in carry out nearby region measurement；Or, when selection be SL Gap when, data packet is transmitted in SL Gap, so that UE still can carry out nearby region measurement in measurement Gap or transmit data packet in SL Gap, it is not necessary to measurement Gap and the SL Gap being staggered completely each other for configuration when measurement Gap and SL Gap conflict, to solve measurement Gap and the SL Gap that configuration is staggered completely each other, cause the difficulty for configuring Gap big, the low problem of allocative efficiency has achieved the effect that the efficiency for improving configuration Gap.

In addition, by whether belonging to PS service selection measurement measurement Gap SL Gap according to the data packet that will be transmitted in SL Gap, it can be when data packet belongs to PS business, the data packet that determination will be transmitted on SL by SL Gap is very urgent, SL Gap is selected, preferentially at this time to guarantee being normally carried out for business.

Refer to Fig. 7, it illustrates the method flow diagram of another Gap selection method provided in an embodiment of the present invention, whether UE belongs to relief performance group (reduced performance group) selection measurement Gap SL Gap according to the frequency where adjacent area in the present embodiment.The Gap selection method may include:

Step 701, base station is determined as the measurement Gap of UE configuration.

Step 702, base station generates configuration information, which is used to indicate the time that measurement Gap occurs.

Step 703, base station sends configuration information to UE.

Step 704, UE receives the configuration information that base station is sent.

Step 705, the time that UE occurs according to the measurement Gap time occurred and SL Gap, judge to measure whether Gap conflicts with SL Gap, the time which occurs is configured according to predetermined policy.

Wherein, the realization process of step 701-705 is detailed in the description in step 301-305, does not repeat herein.

Step 706, when measurement Gap conflicts with SL Gap, whether the frequency where UE determines adjacent area belongs to relief performance group, and relief performance group is the frequency grouping that delay performance is worst in each frequency grouping, and frequency grouping is grouped to the frequency of measurement needed for UE.

It is generally not the measurement for mobility service to the measurement that the frequency in relief performance group carries out.For example, measuring the cell for seeking unloading to the frequency in relief performance group or finding accessible AP etc..It is not used to find changeable adjacent cell due to measuring the frequency in relief performance group, therefore, it is generally not very urgent for measuring to the frequency in relief performance group, and whether UE can belong to relief performance group according to the frequency where adjacent area to select measurement Gap SL Gap.

In general, base station includes at least one survey to UE sending measuring configuration information, in the measurement configuration information Frequency is measured, and each measurement frequency belongs to one of them in two frequency groupings, one in the grouping of the two frequencies is relief performance group, another is normal performance group.In specific implementation, UE can first determination will frequency in measurement Gap where the adjacent area that measure, then determine that frequency belonging to the frequency is grouped, whether the frequency that the frequency according to belonging to it is grouped where determining the adjacent area belongs to relief performance group.

Step 707, when frequency is not belonging to relief performance group, UE selection measurement Gap executes step 708.

When the frequency where adjacent area is not belonging to relief performance group, show that UE may find changeable adjacent cell by nearby region measurement, the signal quality of serving cell may be poor at this time, UE preferentially selects measurement Gap to carry out nearby region measurement, to when the signal of adjacent cell is preferable, adjacent cell is switched to the serving cell of UE in time, to guarantee the normal communication of UE.

Step 708, UE carries out nearby region measurement in measurement Gap, terminates process.

Step 709, when the frequency where adjacent area belongs to relief performance group, UE selects SL Gap.

When the frequency where adjacent area belongs to relief performance group, show that the nearby region measurement is not very urgent, the SL Gap of UE selection at this time.

Step 710, UE transmits data packet in SL Gap.

In addition, by selecting measurement Gap SL Gap according to whether the frequency where adjacent area belongs to relief performance group, it can be when the frequency where adjacent area be not belonging to relief performance group, determine that UE may find changeable adjacent cell by nearby region measurement, the signal quality of serving cell may be poor at this time, and UE preferentially selects measurement Gap to carry out nearby region measurement, thus when the signal of adjacent cell is preferable, adjacent cell is switched to the serving cell of UE in time, to guarantee the normal communication of UE.

Fig. 8 is referred to, it illustrates the method flow diagram of another Gap selection method provided in an embodiment of the present invention, UE is for received data packet or to be used to send data packet selection measurement Gap SL Gap according to SL Gap in the present embodiment.The Gap selection method may include:

Step 801, base station is determined as the measurement Gap of UE configuration.

Step 802, base station generates configuration information, which is used to indicate the time that measurement Gap occurs.

Step 803, base station sends configuration information to UE.

Step 804, UE receives the configuration information that base station is sent.

Step 805, the time that UE occurs according to the measurement Gap time occurred and SL Gap, judge to measure whether Gap conflicts with SL Gap, the time which occurs is configured according to predetermined policy.

Wherein, the realization process of step 801-805 is detailed in the description in step 301-305, does not repeat herein.

Step 806, when measurement Gap conflicts with SL Gap, UE determines that SL Gap is for received data packet or to be used to send data packet, SL Gap is for received data packet or being used to send data packet is that base station indicates, alternatively, SL Gap is for received data packet or being used to send data packet is that UE is determined.

It in one possible implementation, is for received data packet or to be used to send data packet by base station instruction SL Gap；In alternatively possible implementation, determine that SL Gap is for received data packet or to be used to send data packet by UE.Wherein, when determining that SL Gap is for received data packet or when being used to send data packet by UE, it is for received data packet or to be used to send data packet that UE, which can read SL Gap specified in communication protocol,；Alternatively, UE can determine that SL Gap is for received data packet or to be used to send data packet with itself.When UE itself determines that SL Gap is for received data packet or when being used to send data packet, SL Gap can be for received data packet or to be used to send data packet notice base station by UE, can not also notify base station, this embodiment is not limited.

When being for received data packet or when being used to send data packet by base station instruction SL Gap, method provided in this embodiment, further include: base station is for received data packet or to be used to send data packet to UE instruction SL Gap, and SL Gap is for received data packet or being used to send data packet is used to indicate UE selection measurement Gap SL Gap.

Optionally, base station can indicate that SL Gap is for received data packet or to be used to send data packet by the configuration information in step 802, indicate that SL Gap is for received data packet or to be used to send data the wasted signaling of packet to save base station by additional configuration information.

In the present embodiment, UE selection can measure Gap when SL Gap is used to received data packet, and SL Gap is selected when SL Gap is used to send data packet；It is selection measurement Gap that UE, which can also be used to send data packet in SL Gap, and SL Gap is selected when SL Gap is used to received data packet.In one possible implementation, above-mentioned selection rule is issued by base station；In alternatively possible implementation, above-mentioned selection rule is determined by UE.Wherein, when determining above-mentioned selection rule by UE, UE can read above-mentioned selection rule specified in communication protocol；Alternatively, UE can determine above-mentioned selection rule with itself.When UE itself determines above-mentioned selection rule, above-mentioned selection rule can be notified base station by UE, can not also notify base station, this Embodiment is not construed as limiting.

When multiple UE are communicated on SL simultaneously each other, due to that a UE can only be supported to send data packet in synchronization, other UE received data packets, the duration that each UE sends data packet is far smaller than the duration of received data packet, and therefore, the importance for sending data packet is higher than the importance of received data packet, preferably, UE selection measurement Gap when SL Gap is used to received data packet, selects SL Gap, when SL Gap is used to send data packet to guarantee the normal transmission of data packet.

Wherein, the duration of data packet and the duration of received data packet are sent in order to facilitate understanding, the present embodiment is illustrated so that the SL carried out between 5 UE 10 minutes is communicated as an example, then each UE transmission data packet when it is 2 minutes a length of, received data packet when it is 8 minutes a length of.

Step 807, when SL Gap is used to received data packet, UE selection measurement Gap executes step 808.

Step 808, UE carries out nearby region measurement in measurement Gap, terminates process.

Step 809, when SL Gap is used to send data packet, UE selects SL Gap.

Step 810, UE transmits data packet in SL Gap.

In addition, by being for received data packet or to be used to send data packet selection measurement Gap SL Gap according to SL Gap, SL Gap can be selected when SL Gap is used to send data packet, importance due to sending data packet is higher than the importance of received data packet, therefore, UE preferentially selects SL Gap to send data packet, to guarantee the normal transmission of data packet.
