Background

At present, the application of the mobile internet is rapidly developed, and users increasingly rely on mobile connection anytime and anywhere. Connection stability and mobile continuity of a mobile terminal are key factors affecting user experience. Nowadays, a plurality of wireless network Access technologies coexist, such as Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), etc., and an upgraded Long Term Evolution System (LTE-Advanced Pro), i.e., 4.5G, being commercially deployed and a future fifth Generation (5th Generation, 5G) Mobile Communication network being standardized, and the deployment density of base stations is increasing in order to meet increasing user demands.

In order to ensure that the mobile terminal can always access the cell with good signal quality, the terminal is required to measure the frequency point of the serving cell and the frequency points around the cell, and switch to the cell with the optimal quality according to the measurement result. However, due to the multi-access technology and the high-density network deployment, the number of frequency points to be measured around the serving cell increases, but the available measurement gaps do not increase, and the number of truly effective and stable frequency points is limited. Therefore, the real-time performance of the measurement result cannot be guaranteed, and the faded frequency point is reported to the network. Therefore, the prior art is difficult to ensure the accuracy of the measurement result and cannot ensure the connection stability and the movement continuity of the mobile terminal.

In this embodiment of the present application, the timer may be a TimeToTrigger timer, where the duration of the initial timer is a time period between when the timer is triggered to generate a measurement report, in the time period, the terminal continues to measure a plurality of frequency points to be measured, and when the time period ends, the terminal generates the measurement report. The measurement report includes: triggering events of the timer and frequency point information meeting triggering conditions. Optionally, if the frequency point meeting the entry condition of the certain trigger event meets the exit condition within the duration of the initial timer, and the event meeting the exit condition is measured, the timer is terminated in advance.

The measurement GAP can be measured on the frequency point of the current service cell, the obtained measurement opportunities are many, but the measurement GAP configured by the network end is occupied for the measurement of the frequency points of the different frequency and the different system frequency, the measurement GAP can be at least one of the measurement GAP or the non-activation period of the CDRX, the measurement GAP means that the frequency points of the different frequency or the different system frequency are measured on the frequency points different from the service cell in the time period appointed by the base station and the wireless terminal, the condition of the non-activation period of the CDRX is similar, the service area of the CDRX non-activation period does not do business, so the radio frequency channel of the front end can be switched to the frequency points for measurement, the number of the measurement GAPs is configured by the network end, and the number is limited. The radio frequency channel may be the transceiver 303 of the terminal 30 in fig. 2, and specifically may be a receiver Rx for receiving a frequency point signal to be measured. When the receiver Rx is switched to a frequency point, the receiver Rx receives a signal of the frequency point to perform measurement, such as obtaining reference signal receiving power or reference signal receiving quality of the frequency point to be measured. The specific technical scheme of the embodiment of the application mainly aims at the measurement of the different frequency points and the different system frequency points, and the problems that the measurement result is inaccurate due to the limited measurement clearance and the large number of the different frequency points and the different system frequency points to be measured are solved.

402. And determining the initial measurement sequence of the frequency points to be measured.

In this embodiment of the present application, before measuring a plurality of frequency points to be measured, a terminal may determine an initial measurement sequence for the plurality of frequency points to be measured configured by a network terminal by comprehensively referring to a plurality of information, where the comprehensively referring to the plurality of information includes: at least one of the advancement of the wireless access technology of the multiple frequency points to be tested, big data configuration information or pre-configuration information.

The advancement of the wireless access technology of the reference frequency point to be tested comprises the following steps: the method comprises the steps that higher measurement priority is given to frequency points to be measured with more advanced wireless access technology, if the frequency points to be measured have 4G frequency points and WCDMA frequency points, the 4G access technology is advanced, and the measurement sequence of the 4G frequency points is placed before the measurement sequence of the WCDMA frequency points; the frequency points to be measured with more advanced wireless access technology are endowed with higher measurement frequency, so that the probability that the access technology or the access frequency points with high priority acquire the measurement GAP is increased, the probability that the frequency points with more advanced wireless access technology have good signal quality is higher, the probability of meeting the threshold is higher, more measurement opportunities are allocated to the frequency points to be measured with more advanced wireless access technology, the limited measurement GAP can be prevented from being used for measuring invalid pilot frequency points or inter-system frequency points, and the utilization rate of the measurement GAP is improved as much as possible. For example, the current serving cell of the wireless terminal is a 4.5G cell, the frequency points to be tested configured by the network include two different frequency points FREQ1 and FREQ2 in the 4.5G module, and two different system frequency points WF1 and WF2 with two access technologies of WCDMA, and the best service experience provided for the wireless terminal user should be switched to the 4.5G cell instead of the WCDMA cell as much as possible in the moving process. The initial measurement sequence of the frequency points to be measured is FREQ1- > FREQ2- > WF1- > WF2, and after the measurement sequence is adjusted based on the priority of the frequency points to be measured, the measurement sequence can be as follows: FREQ1- > FREQ2- > FREQ1- > FREQ2- > WF1- > WF2, the probability of obtaining the measurement GAP by the FREQ1 and the FREQ2 with high priority is high, the ratio of the measurement GAP obtained by other points to be measured is 2:1, the ratio can be flexibly adjusted according to the specific sample amount to be measured and other measurement factors, and the ratio is not limited by the technical scheme in the embodiment of the application.

The big data configuration information includes: the big data configuration information is obtained based on terminal behavior information, the terminal reports the behavior information of the terminal to a central server, and the central server comprehensively obtains data information to perform big data analysis, wherein the terminal behavior information comprises: the method comprises the steps that the access duration of a terminal in a certain frequency point to be measured accounts for the total access duration of the terminal, at least one of the proportion of the access duration of the terminal in a certain wireless access technology accounts for the total access duration of the terminal and the signal quality stability statistical result of the terminal access frequency point is obtained, and higher measurement priority is given to the frequency point to be measured with a higher access duration proportion, the frequency point to be measured with a wireless access technology with a higher access duration proportion and the frequency point to be measured with a better signal quality stability statistical result.

The pre-configuration information includes: the provisioning information is stored in a configuration file of the wireless terminal, and provides information similar to that of big data configuration, except that the provisioning information is configured when the wireless terminal leaves the factory, the updating of the provisioning information depends on the upgrading of the terminal version, and the big data configuration information changes according to the specific behavior of the terminal or the change of the service scene.

The measurement to serving cell frequency point and same frequency point just can go on the frequency point of current serving cell, the measuring chance that obtains is more, the measurement to different frequency point and different system frequency point just can measure when the measurement clearance arrives, and the measurement clearance is limited, the different frequency point and the different system frequency point that await measuring are more, consequently to the frequency point that more probably has stable high quality signal, more probably provide priority measurement such as frequency point of better service experience for the user, improve the utilization ratio of measuring the clearance, ensure that the measuring result is accurate, real-time key.

403. And measuring the multiple frequency points to be measured based on the initial measurement sequence to obtain the current frequency point meeting the triggering condition, and triggering the timer.

After the initial measurement sequence of the frequency points to be measured is determined, sequentially measuring a plurality of frequency points to be measured based on the initial measurement sequence, wherein the measurement of the points to be measured comprises the measurement of the frequency points of the service cell or the same frequency points on the frequency points of the current service cell and the measurement of the different frequency points or the different system frequency points in the inactive period of measuring GAP or CDRX. In the measurement process, the measurement Reference quantity may be at least one of Reference Signal Receiving Power (RSRP) of the frequency point to be measured or Reference Signal Receiving Quality (RSRQ) of the frequency point to be measured. Comparing the RSRP or RSRQ of a certain frequency point to be tested with a threshold corresponding to a trigger event related to the frequency point, when the entering condition of the trigger event is met, considering the frequency point to be tested as a current frequency point meeting the trigger condition, acquiring the current frequency point, and triggering a TimeToTrigger timer, wherein the TimeToTrigger timer is timed according to the duration of an initial timer configured by a network terminal. Specifically, the first frequency point meeting the trigger condition is taken as the current frequency point when the measurement is performed according to the initial measurement sequence of the frequency point to be measured.

404. And within the duration of an initial timer, measuring the frequency points to be measured until the timer stops timing to obtain a measurement result, wherein the measurement result comprises the current frequency point still meeting the triggering condition.

And within the duration of the initial timer, the terminal continues to measure the multiple frequency points to be measured according to the initial measurement sequence, the current frequency point is considered to still meet the trigger condition when the timer stops counting, and a measurement result is obtained, wherein the measurement result comprises the current frequency point still meeting the trigger condition and a trigger event associated with the current frequency point. However, in actual measurement, because there are many pilot frequency points and pilot system frequency points to be measured, and the number of measurement GAPs in the duration of the initial timer is limited, if the measurement is still performed in a predetermined sequence as in the prior art, the current frequency point of the trigger timer may not obtain a measurement opportunity in the duration of the initial timer, and if the frequency point of the trigger timer meets the departure condition, but is not measured, the measurement instantaneity and accuracy of the frequency point are affected. In order to improve the real-time performance and accuracy of the measurement, in the embodiment of the present application, the measuring the multiple frequency points to be measured includes: and ignoring the initial measurement sequence of the frequency points to be measured, and measuring the current frequency points meeting the triggering conditions at least once. In an optional scheme, an implementation manner of performing at least one measurement on a current frequency point meeting a trigger condition may be: and measuring the current frequency point meeting the triggering condition in at least one of a plurality of measurement gaps configured by the network terminal in the duration of the initial timer.

To describe the present solution more clearly, a signaling interaction process 500 of the present solution in a specific application scenario is shown in fig. 5.

501. And the network end sends a measurement configuration signal.

For specific information of the measurement configuration information, the description in step 401 is referred to. In this specific application scenario, the measurement configuration signal sent by the network includes: the 6 frequency points to be measured are respectively a 4G service cell frequency point F1, a common frequency point F2, two wireless access technologies of different system frequency points F3 and F4 of WCDMA, two wireless access technologies of different frequency points F5 and F6 of 4G, a trigger event is an A5 event and corresponding threshold values Thr1 and Thr2, the duration of an initial timer is T, and a measurement GAP is a measurement GAP.

502. The serving cell frequency point F1 is measured.

503. The same frequency point F2 is measured.

Before the GAP measurement comes, the measurement performed on the serving cell frequency point and the co-frequency point on the frequency point where the serving cell is located may be repeated many times, and for clarity, only one set of measurements is shown in fig. 5 as an example, which is not to say that only one set of measurements is performed before the GAP measurement comes. And comparing the RSRQ of the serving cell frequency point F1 and the same frequency point F2 with threshold values respectively according to the reference signal quantity RSRQ in the measurement process.

504. The measurement iso-frequency point F5 is higher than Thr 2.

Because the measurement of the serving cell frequency point F1 and the common frequency point F2 can be performed on the frequency points of the serving cell, and the measurement can be repeated for many times, the initial measurement sequence is determined only for the different frequency points and the different system frequency points occupying the measurement GAP, and the initial measurement sequence of the frequency points to be measured is determined according to the scheme in step 402, and the initial measurement sequence is the sequence in which the different frequency points to be measured and the different system frequency points acquire the measurement GAP: f5- > F6- > F3- > F4. Therefore, when the first measurement GAP comes, the terminal switches to the measurement GAP to measure the alien frequency point F5, and at this time, the RSRQ of the alien frequency point F5 is higher than the second threshold Thr2, which satisfies the second entry condition of the a5 event.

505. And measuring the frequency point F1 of the serving cell, which is lower than Thr 1.

After the GAP measurement is finished, the terminal switches back to the frequency point where the serving cell is located to measure the serving cell frequency point, and at the moment, the RSRQ of the serving cell frequency point is lower than a first threshold Thr1, so that a first entering condition of an A5 event is met. At this point, both entry conditions of the a5 event are satisfied, an a5 event is entered, and the TimeToTrigger timer is triggered to count with the initial timer duration T.

506. The same frequency point F2 is measured.

Similarly, before the second measurement GAP comes, the measurement performed on the serving cell frequency point and the common frequency point on the frequency point where the serving cell is located may be repeated many times, and only one set is shown in fig. 5 as an example.

507. The iso-frequency point F6 is measured.

According to the initial measurement sequence, the frequency point of the second acquired measurement GAP is the pilot frequency point F6, so when the second measurement GAP arrives, the terminal switches to the measurement GAP to measure the pilot frequency point F6. After the measurement of the pilot frequency point F6 is finished, the terminal switches back to the frequency point where the serving cell is located to measure the serving cell frequency point F1 and the same frequency point F2, and for clarity, the repeated measurement of the serving cell frequency point F1 and the same frequency point F2 is omitted in fig. 5, and the measurement of the pilot frequency point and the inter-system frequency point in the measurement GAP is mainly shown.

508. The iso-frequency point F5 is measured.

According to the above measurement process, it can be known that there are many opportunities for the serving cell frequency point and the co-frequency point to obtain measurement, and therefore if the serving cell frequency point F1 changes and no longer meets the entry condition, the change can be measured in time. However, in the specific application scenario, within the duration of the initial timer, the network only configures three measurement GAPs, if the three measurement GAPs after the timer is triggered are used to measure the different frequency point F6 and the different system frequency points F3 and F4 respectively according to the initial measurement sequence, the different frequency point F5 cannot be measured again within the duration of the initial timer, if the signal quality of the different frequency point changes at the time T1 shown in fig. 5, the RSRQ of the different frequency point is lower than the second threshold Thr2, which satisfies the leaving condition, but the different frequency point F5 does not obtain a measurement opportunity, which results in that the timer cannot be stopped in time when the leaving condition is satisfied. Therefore, in the scheme, the initial measurement sequence of the frequency point to be measured is ignored, and when the third measurement GAP arrives, the inter-frequency point F5 is measured instead of the inter-system frequency point F3 being measured according to the initial measurement sequence. If the alien frequency point F5 still satisfies the second entry condition for the A5 event, the measurement proceeds 509. And if the pilot frequency point F5 meets the leaving condition, stopping the timer in time and canceling the report of the pilot frequency point F5.

509. And measuring an inter-system frequency point F3.

Since the inter-frequency point F5 meeting the second entry condition of the event A5 is inserted before the inter-system frequency point F3 for measurement in order to ensure the accuracy of the measurement result, which corresponds to the change of the measurement sequence from F6- > F3- > F4 to F6- > F5- > F3- > F4, when the fourth measurement GAP arrives, the terminal is switched to the measurement GAP to measure the inter-system frequency point F3.

510. And when the timer is overtime, reporting the abnormal frequency point F5 to the network terminal.

Because the leaving condition is not met within the duration of the initial timer, a measurement result is obtained when the timer is overtime, the measurement result includes the alien frequency point F5 which still meets the second entering condition of the a5 event, and the measurement result also includes the type of the triggering event, i.e., the a5 event, and the terminal reports both the alien frequency point F5 and the a5 event to the network terminal.

In another possible case, the RSRQ of the alien frequency point F5 at time T1 shown in fig. 5 is lower than the second threshold, and the departure condition is satisfied, when the alien frequency point F5 is measured in step 508, the departure condition is detected in time, the timer is stopped, the report of the measurement report of the alien frequency point F5 is cancelled, and the frequency point that has faded is prevented from being reported to the network.

In addition, in fig. 5, the different-frequency point F5 that meets the trigger condition is measured in the third measurement GAP, which is only an implementation manner of the scheme in the embodiment of the present application, and the different-frequency point F5 may also be measured in the second or fourth measurement GAPs, this scheme does not limit the order in which the measurement GAPs are occupied, and the different-frequency point F5 may also be measured in any two measurement GAPs, as long as it is ensured that at least one measurement GAP of the measurement GAPs within the duration of the initial timer is used for measuring the different-frequency point F5, generally speaking, the different-frequency point F5 is measured in the measurement GAPs closer to the time at which the timer stops timing, and the accuracy of the obtained measurement result is higher.

According to the scheme in the embodiment of the application, at least one measurement on the current frequency point of the trigger timer is ensured within the time length of the initial timer, so that when the signal quality variation of the current frequency point meets the leaving condition, the terminal can timely find the signal quality variation through the measurement, the timer is stopped, and the inaccurate measurement result is avoided.

405. And reporting a measurement report to a network terminal, wherein the measurement report comprises the measurement result.

And the terminal generates a measurement report according to the obtained measurement result and reports the measurement report to the network terminal, wherein the measurement result comprises the current frequency point still meeting the triggering condition and the type of the specific triggering event in the triggering condition. In a possible application scenario, if within the duration of an initial timer, the current frequency point meeting the trigger condition meets the leaving condition and is measured, the timer is terminated in advance, a plurality of frequency points to be measured are continuously measured, a new frequency point to be measured meeting the trigger condition is searched, and the measurement process is repeated until the frequency point to be measured which can be reported to a network end is obtained.

Fig. 6 is a flowchart of another specific frequency point measuring method according to the embodiment of the present application.

601. And receiving the measurement configuration information sent by the network terminal.

As with step 401, refer to the description in step 401.

602. And dividing the frequency points to be measured with the same triggering conditions into a group to obtain a frequency point set to be measured.

When the network performs measurement configuration, different trigger events may be configured for different frequency points to be measured, for example, the trigger event configured for two different frequency points FREQ1 and FREQ2 at the network is an a4 event, the trigger event configured for two different system frequency points FREQ3 and FREQ4 is a B1 event, and it is assumed that the initial measurement sequence is FREQ1- > FREQ2- > FREQ3- > FREQ4, the different frequency point FREQ1 is measured first and meets the entry condition of the a4 event, and the leaving condition is not met in the duration of the initial timer, and the different frequency point FREQ1 is reported to the network. But the inter-frequency point FREQ2 is a cell with better signal quality but is not measured, with the end result that the terminal may switch to a non-optimal cell. Therefore, in order to obtain the measurement result of the best cell, in the measurement scheme of this embodiment, the frequency points to be measured that satisfy the same trigger condition are divided into a group, so as to obtain two frequency point sets to be measured:

configuring frequency point sets FREQ1 and FREQ2 to be tested of an A4 event;

and configuring frequency point sets FREQ3 and FREQ4 to be tested of the B1 event.

603. And measuring the frequency point set to be measured to obtain a plurality of frequency points meeting the triggering conditions in the frequency point set to be measured, taking the frequency point with the optimal signal quality in the frequency points as the current frequency point, and triggering a timer.

More than one frequency point meeting the trigger condition in the frequency points to be tested configured with the same trigger condition may be configured, so if the first frequency point meeting the trigger condition is taken as the current frequency point and triggers the timer, the obtained measurement result may not be optimal. Therefore, the frequency points to be detected are grouped according to the triggering conditions, the frequency points to be detected with the same triggering conditions are used as a frequency point set to be detected, then, each frequency point in the frequency point set to be detected is measured to obtain a plurality of frequency points to be detected which meet the triggering conditions, the point with the optimal signal quality in the frequency points to be detected which meet the triggering conditions is selected as the current frequency point, and the timer is triggered.

604. And within the duration of an initial timer, measuring the frequency points to be measured until the timer stops timing to obtain a measurement result, wherein the measurement result comprises the current frequency point still meeting the triggering condition.

As with step 404, reference is made to the description in step 404.

605. And reporting a measurement report to a network terminal, wherein the measurement report comprises the measurement result.

As with step 405, reference is made to the description in step 405.

In order to describe the scheme in step 602 and step 603 more clearly, the signaling interaction process 700 of the scheme in a specific application scenario is given below as shown in fig. 7.

701. And the network end sends a measurement configuration signal.

The network side is configured with a serving cell frequency point F1, a common frequency point measurement F2, two different frequency points FREQ1 and FREQ2, and two different system frequency points FREQ3 and FREQ4, wherein the trigger events configured by FREQ1 and FREQ2 are the same and are both A4 events, and the trigger events configured by the other two frequency points FREQ3 and FREQ4 to be measured are the same and are both B1 events. According to the description in step 602, the frequency point to be measured is divided into two frequency point sets to be measured, the sequence of receiving and measuring GAP by the pilot frequency point and the inter-system frequency point is FREQ1(a4) - > FREQ2(a4) - > FREQ3(B1) - > FREQ4(B1), the threshold corresponding to the event of a4 is Thr, and the threshold corresponding to the event of B1 is ThrB.

702. The serving cell frequency point F1 is measured.

703. The same frequency point F2 is measured.

Before the GAP measurement comes, the measurement performed on the serving cell frequency point and the co-frequency point on the frequency point where the serving cell is located may be repeated many times, and for clarity, only one set of measurements is shown in fig. 7 as an example, which is not to say that only one set of measurements is performed before the GAP measurement comes. The reference signal quantity according to in the measurement process is RSRQ.

704. The pilot frequency point FREQ1 is measured to be greater than Thr.

When the measurement GAP arrives, the terminal is switched to the measurement GAP to measure the pilot frequency point FREQ1, at the moment, the RSRQ of the pilot frequency point FREQ1 is larger than the threshold Thr corresponding to the A4 event, the entry condition of the A4 event is met, but the frequency points to be measured, which are configured with the A4 event, are concentrated and the frequency point FREQ2 to be measured is not measured, so that the TimeToTrigger timer is not triggered temporarily.

705. The serving cell frequency point F1 is measured.

The terminal switches back to the frequency point where the serving cell is located and measures the serving cell frequency point F1.

706. The same frequency point F2 is measured.

Similarly, before the measurement GAP arrives, the measurement performed on the serving cell frequency point and the common frequency point on the frequency point where the serving cell is located may be repeated many times, and only one group is shown in fig. 7 as an example.

707. The pilot frequency point FREQ2 is measured to be greater than Thr.

When the measurement GAP comes, the terminal is switched to the measurement GAP to measure the pilot frequency 2, and at this time, the RSRQ of the pilot frequency 1 is greater than the threshold Thr corresponding to the a4 event, so that the entry condition of the a4 event is met. At this time, the configured frequency points to be tested with the triggering event of A4 are completely measured, two frequency points to be tested, FREQ1 and FREQ2 which meet triggering conditions are obtained, the RSRQ of the two frequency points to be tested is compared, the RSRQ of the FREQ2 is superior to that of the FREQ1, and therefore the different frequency point FREQ2 is selected as the current frequency point of the triggering timer and the timer is triggered.

708. And measuring a frequency point FREQ3 of the different system.

Between step 707 and step 708, the terminal switches back to the frequency point where the serving cell is located, and measures the serving cell frequency point F1 and the same frequency point F2, and fig. 7 omits the repeated measurement process for F1 and F2. When the measurement GAP comes, the terminal is switched to the measurement GAP to measure the frequency point FREQ3 of the different system.

709. And when the timer is overtime, reporting the events of the pilot frequency point FREQ2 and A4 to the network side.

The measurement procedure during the initial timer period refers to the measurement scheme shown in fig. 5, and the measurement scheme shown in fig. 7 omits the contents of this part. Within the duration of the initial timer, the pilot frequency point FREQ2 does not satisfy the departure condition, and when the timer stops timing, the measured pilot frequency point FREQ2 and the corresponding a4 event are reported to the network.

710. The network indicates the handover.

The network may instruct the terminal to switch to the cell where the pilot frequency point FREQ2 is located according to the received measurement report.

In an optional implementation scheme, if there are more frequency points to be measured with the same trigger conditions, the following problems may occur when all frequency points with the same trigger conditions are measured and then the frequency point with the optimal signal quality is compared: the serving cell signal is already poor, but the measurement of the frequency point to be measured with the same trigger condition is not finished yet, and the terminal cannot be switched to the cell frequency point with good quality in time. To avoid the above situation, referring to fig. 7, when the serving cell signal deteriorates, the TimeToTrigger timer is triggered when the pilot frequency point FREQ1 meeting the entry condition of the a4 event is detected in step 704, and in the TimeToTrigger timer, if the pilot frequency point FREQ2 also meets the entry condition of the a4 event and the signal quality is better, the running TimeToTrigger timer is stopped, and the pilot frequency point FREQ2 triggers the timer again.

Another specific frequency point measurement method flow chart in the embodiment of the present application is given below, and as shown in fig. 8, the measurement method is another implementation manner of performing at least one measurement on a current frequency point that meets a trigger condition.

In the measurement scheme of fig. 8, the configuration of the network end is the same as the configuration information in the application scenario of fig. 5, and the specific configuration information includes: the method comprises the following steps that a 4G service cell frequency point F1, a common frequency point F2, two wireless access technologies are inter-system frequency points F3 and F4 of WCDMA, two wireless access technologies are inter-frequency points F5 and F6 of 4G, a trigger event is an A5 event and corresponding threshold values Thr1 and Thr2, Thr2 is greater than Thr1, the duration of an initial timer is T, a reference signal quantity according to the measurement process is RSRQ, and the initial measurement sequence of the inter-frequency points and the inter-system frequency points, namely the sequence for obtaining measurement GAP, is as follows: f5- > F6- > F3- > F4.

The method specifically comprises the following steps:

801. and measuring an abnormal frequency point F5 which is higher than Thr2, and meets a second entry condition of the A5 event, wherein the time meeting the entry condition is T1.

For simplicity, the method flowchart in fig. 8 starts from the measurement of the different frequency point F5, and omits a plurality of measurement processes on the frequency point of the serving cell F1 and the same frequency point F2 at the frequency point of the current serving cell. When the measurement GAP arrives, the terminal is switched to the measurement GAP to measure the pilot frequency point F5, the RSRQ of F5 is higher than Thr2, the second entering condition of an A5 event is met, and the time when the entering condition is met is recorded as T1.

802. And measuring a frequency point F1 of the serving cell, which is lower than Thr1, meeting the first entering condition of the A5 event and triggering a timer.

After the GAP measurement is finished, the terminal switches back to the frequency point where the serving cell is located to measure the serving cell frequency point, and at the moment, the RSRQ of the serving cell frequency point is lower than a first threshold Thr1, so that a first entering condition of an A5 event is met. At this point, both entry conditions of the a5 event are satisfied, an a5 event is entered, and the TimeToTrigger timer is triggered to time with the initial timer duration T

803. A timeliness threshold value T _ thr is determined.

As mentioned above, after the current frequency point meeting the trigger condition triggers the timer, in order to avoid the frequency point which may be faded from being reported to the network, at least one measurement needs to be performed on the current frequency point within the duration of the initial timer. In order to take account of the utilization rate of the measurement GAP and the accuracy of the measurement result, a time efficiency threshold can be determined, and the time efficiency threshold is not fixed and is obtained by integrating the current measurement information, the service cell condition and other information grasped by the terminal.

804. The measurements are made in the measurement order and the time difference Δ T between the current measurement time T2 and the time T1 is calculated as T2-T1.

The measurement sequence here is the sequence of obtaining measurement GAP by the pilot frequency point and the inter-system frequency point, that is: f5- > F6- > F3- > F4. If no adjustment is made on the measurement, within the time length T of the initial timer, the sequence of obtaining the measurement GAP by the different frequency points and the different system frequency points does not change, namely F5 is measured to measure F6, then F3 and F4 are measured in sequence, the process is carried out circularly, and the measurement sequence ignores the measurement of F1 and F2 on the current service area frequency point. And calculating the time difference between the current measurement time and the time when the pilot frequency point F5 meets the second entering condition, and using the time difference to measure whether additional measurement needs to be carried out on the pilot frequency point F5.

805. Determine if Δ T exceeds a timeliness threshold T _ thr?

And in the timeliness threshold, the quality of the current frequency point signal meeting the trigger condition is considered to be stable, the current frequency point signal does not need to be measured, and the stability of the current frequency point signal quality can not be ensured any more when the current frequency point signal exceeds the timeliness threshold. So if the time interval does not exceed the timeliness threshold, proceed to step 804; if the time interval exceeds the timeliness threshold, step 806 is performed.

806. When the latest measurement GAP arrives, the different frequency point F5 is measured, and the measurement time is recorded as T3.

When the time interval exceeds the timeliness threshold, the measurement result is considered to be not new enough, the signal quality cannot be guaranteed, a measurement needs to be added to the frequency point meeting the entering condition, and the measurement time is recorded as T3. However, the measurement of the inter-frequency point needs to occupy the measurement GAP, so if no measurement GAP is available when the time interval exceeds the timeliness threshold, the measurement of the inter-frequency point F5 needs to be performed after the latest measurement GAP arrives.

807. Determine if exclusive-or point F5 satisfies the leaving condition?

If the leave condition is not satisfied, proceed to step 808.

808. Is the timer expired?

If the timer has not timed out, go to step 809, if the timer has timed out, go to step 810.

809. T3 is assigned to T1, i.e., T1 is T3.

If the timer is not overtime, the measurement continues, and it needs to be determined again that the different frequency point F5 is not new enough, and whether the time difference exceeds the timeliness threshold or not from the last measurement, so the time difference should be calculated by using the last measured time of the different frequency point F5 as the time reference. The time reference is updated and then the process goes to step 804.

810. And obtaining a measurement result, wherein the measurement result comprises the events of the different frequency points F5 and A5 which still meet the triggering condition, and reporting the measurement result to the network terminal.

If the timer is overtime, the measurement result is obtained and a measurement report is generated, and the trigger condition is still met, which indicates that the pilot frequency point F5 does not meet the departure condition within the duration of the initial timer, so that the measurement result is accurate and reliable. The measurement report reported to the network includes type a5 of the trigger event and the inter-frequency point F5 satisfying the event entry condition.

Alternatively, in step 807, if the measurement-time pilot frequency point F5 satisfies the leaving condition of the a5 event with respect to the pilot frequency point F5, the process proceeds to step 811.

811. And stopping the timer, and canceling the report of the pilot frequency point F5.

If the different frequency point F5 meets the leaving condition of the A5 event, the fact that the signal quality of the different frequency point F5 is poor is proved, the different frequency point is no longer suitable for being reported to the network, therefore, the timer is stopped in time, the situation that the frequency point which is already faded is reported to the network is avoided, and the accuracy of the measuring result is ensured.

Another specific frequency point measurement method flow chart in the embodiment of the present application is given below, as shown in fig. 9. The measurement configuration of the network side of the measurement scheme in fig. 9 is the same as the scheme in fig. 8.

Steps 901 to 905 correspond to steps 801 to 805, respectively.

906. Is the remaining time length counted by the timer enough to measure the iso-frequency point F5?

If the remaining time is not enough to measure the iso-frequency point F5, go to step 907. If the remaining time is sufficient, then go to step 908. Because measurement of different frequency points needs to occupy measurement GAP, the following extreme cases may occur: the remaining time length counted by the timer is 5ms, and the duration of the measurement GAP is 6ms, that is, the remaining time length is not enough to measure the different frequency point F5 once, so that the time length of the timer needs to be finely adjusted, so that the remaining time length after the increase is not less than 6 ms.

907. The initial timer duration is increased so that the increased remaining duration is sufficient for one measurement of F5.

The increased remaining time length may be just one measurement of the pilot frequency point F5, or may be longer than the time required for one measurement, and the increased time length is specifically determined by the terminal.

Steps 908-913 correspond to steps 806-811, respectively.
