Embodiment

Basic thought of the present invention is: UE from the network element of network side receive measure Control Parameter after, according to measuring Control Parameter, set up report set and the sub-district in the monitoring collection measured.

Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme.

Below prior art and the present invention are compared elaboration, to embody the advantage of the present invention better with respect to prior art.

With regard to prior art, owing to receive measurement report to RNC from UE acquisition measurement result, triggering measurement report, judgement is switched and RNC notice UE carries out switching, finish these a series of processes and will pass through certain hour, in the meantime, if the wireless environment quality reduces fast under some scene, UE will can not finish normal switching flow because wireless signal is not enough so, thereby have influence on speech quality.Such as, go up along the railway under this scene of UE of high-speed motion, because often experiencing, the residing wireless environment of UE becomes when violent, therefore, cause the wireless environment quality to reduce fast and then have influence on speech quality.

For the present invention, the deficiency that under some scene, exists at top pointed prior art, the invention provides a kind of TD-SCDMA of being applicable to system, be applied in the UE of sub-district when switching and measure and trigger the implementation that measurement report reports, and the UE that uses this scheme.

Might as well get back to the example of above handoff failure shown in Figure 2, the front pointed out the reason of call drop be UE before also not having enough time to finish handoff procedure, the radio signal quality of former sub-district has been passed through low.Therefore to avoid occurring switching call drop, on the one hand, the step of UE reporting measurement reports must be shifted to an earlier date; On the other hand, if network side, specifically be RNC, can obtain the information of more relevant UE wireless environment situations, RNC comprehensive others information just so, measurement report that obtains from the base station such as RNC and the network cell geography information that is kept at RNC inside etc. are made switch decision timely and accurately.Based on above-mentioned consideration, in the present invention, UE should be in more early, reports more measurement report about the signal quality of neighbor cell and current service cell to RNC.

Design of the present invention mainly is: in UE, sets the set of a reporting subdistrict, comprises the concentrated sub-district of monitoring of n signal quality the best in this set, and n 〉=2, the concrete value of n can be determined by the network side appointment or according to the disposal ability of UE.Be not better than sub-district in the report set in the cell signal quality in the report set when UE finds certain in measurement, UE upgrades report set so, promptly the good sub-district of signal quality is joined report set, and original in report set the sub-district of poor signal quality remove.For the sub-district in the report set, UE or report their measurement report periodically to network side; Perhaps when upgrading report set to the network side reporting measurement reports.These the two kinds modes that trigger the UE reporting measurement reports can exist simultaneously, also can only adopt wherein a kind of.

Compared with prior art, the present invention is by introducing report set, changed the mode of UE to the network side reporting measurement reports, make UE report the signal quality situation of more monitorings sub-district to network side, increased the grasp degree of RNC to UE wireless environment of living in, RNC just can be in conjunction with out of Memory like this, and the speed of the measurement report that reports such as the base station, the Doppler frequency shift value of UE, UE and network geographic information wait and provide that switch decision and target switching cell are selected more timely and accurately.Simultaneously, because the sub-district that UE need report is expanded as n, and the report set that wherein any one renewal all can cause UE upgrades, therefore, the present invention compared to existing technology, objectively be equivalent to and played the effect that reports ahead of time, thus UE can be as soon as possible, reporting information is given RNC as much as possible, makes RNC can reach preferable switching effect when carrying out the UE switch decision.

Below the UE that measures and trigger method, the system of measurement report and use this method based on report set of the present invention is specifically addressed.

A kind ofly measure and trigger the method for measurement report based on report set, this method comprises: UE from the network element of network side receive measure Control Parameter after, according to measuring Control Parameter, set up report set and the sub-district in the monitoring collection measured.Wherein, the network element of network side can be RNC.

Here, measure Control Parameter and comprise: the size of report set, neighbor cell list and measurement parameter, and the mode of optional UE reporting measurement reports and optional supplementary parameter.Wherein, because these three parameters of size, neighbor cell list and measurement parameter of report set are essential, and indispensable; The mode of UE reporting measurement reports and supplementary parameter are optional.Therefore, measuring Control Parameter can comprise: the size of report set, neighbor cell list and measurement parameter; Measuring Control Parameter can comprise: the mode of the size of report set, neighbor cell list and measurement parameter and UE reporting measurement reports; Measuring Control Parameter can also comprise: the mode and the supplementary parameter of the size of report set, neighbor cell list and measurement parameter and UE reporting measurement reports.

At the size of measuring the report set in the Control Parameter, the network element of network side has two kinds of advice methods to inform this parameter of UE, first kind of mode: the size of report set is handed down to UE by the network element of network side by measuring control messages.The second way: the size of report set is by agreement in advance between the network element of network side and the UE.

When the network element of network side adopts measurement control messages sending measuring Control Parameter, two kinds of specific implementations are arranged, first kind of specific implementation: the size of report set, neighbor cell list and measurement parameter, and optionally the UE reporting measurement reports mode and optionally supplementary parameter be encapsulated in one and measure in the control messages, be handed down to UE by the network element of network side.Second kind of specific implementation: the size of report set, neighbor cell list and measurement parameter, and optionally the UE reporting measurement reports mode and optionally supplementary parameter be encapsulated in many and measure in the control messages, be handed down to UE by the network element of network side; Wherein, measure in the control messages for every, comprise size, neighbor cell list and the measurement parameter of measuring report set in the Control Parameter, and the arbitrary parameter combination in the mode of optional UE reporting measurement reports and the optional supplementary parameter.

According to measuring Control Parameter, set up report set and detailed process that the sub-district in the monitoring collection is measured comprises: according to the size of report set, UE chooses in the monitoring collection and is no less than n sub-district and sets up report set; Wherein, n 〉=2, the value of n is specified by network side or is determined by the disposal ability of UE.According to neighbor cell list and measurement parameter, UE measures the sub-district in the monitoring collection.

Wherein, choose in the monitoring collection at UE and to be no less than n sub-district and to set up report set, comprise two kinds of situations, first kind of situation is to choose n sub-district to set up report set; Second kind of situation is to choose less than n sub-district to set up report set.Specifically, a specific implementation of first kind of situation is: by optional approach, UE chooses n sub-district arbitrarily in the monitoring collection, to set up report set; Another specific implementation of first kind of situation is: according to neighbor cell list and measurement parameter, by mode is selected in the survey of the cell measurement in the monitoring collection, UE is from monitoring n sub-district choosing signal quality the best in the collection, to set up report set.One specific implementation of second kind of situation is: when the UE ability can not be supported n sub-district measured or can't set up the report set that contains n sub-district the time, UE chooses in the monitoring collection according to the ability of self and is less than n sub-district, to set up report set.

Here, this method further comprises: when measurement result satisfied the trigger condition of report set renewal, UE upgraded report set; The trigger condition that report set upgrades is: the signal quality of the sub-district in report set is not better than the signal quality of the sub-district in the report set.

Here, when UE received the mode of different UE reporting measurement reports, this method further comprised: UE carries out the measurement of corresponding mode and the network element that reporting measurement reports is given network side to the sub-district in the monitoring collection.That is to say that when UE satisfied the mode of measuring UE reporting measurement reports set in the Control Parameter, UE was to the reported by network elements measurement report of network side.Wherein, the mode of UE reporting measurement reports comprises: at least a in the mode that the network element that report set upgrades mode that UE reports immediately, mode that UE periodically reports, network side reports by order notice UE.

Because the mode difference of UE reporting measurement reports, therefore, measure and reporting measurement reports also different, below set forth wherein two kinds of situations respectively for example.

First kind of situation: the mode at the UE reporting measurement reports is: under the situation of the mode that report set renewal UE reports immediately, carrying out the measurement and the reporting measurement reports of corresponding mode specifically comprises for the network element of network side: according to neighbor cell list and measurement parameter, UE remains the sub-district in the monitoring collection is measured, when satisfying the trigger condition that report set upgrades, measurement result upgrades report set, and to the reported by network elements measurement report of network side.

Here, the trigger condition that report set upgrades specifically comprises: UE finds that the signal quality of the sub-district in report set not is better than the signal quality of the sub-district in the report set in measurement.

Here, upgrading report set is specially: the not sub-district in report set that signal quality is excellent joins report set, and the sub-district in the ropy report set of respective signal is removed from report set.

Here, the measurement report that reports has two kinds of specific implementations, first kind: the measurement report that reports is: the measurement report of all sub-districts in the report set after report set upgrades; Second kind: the measurement report that reports is: the measurement report of the measurement report of interior all sub-districts of report set after report set upgrades and the sub-district of removing from report set.

Here, the information in the measurement report comprises at least: UE reporting measurement reports former is because the cell id of report set update event, each sub-district and corresponding to the measurement result of each sub-district.

When UE received supplementary parameter, this method further comprised: revise the trigger condition that report set upgrades; Wherein, supplementary parameter comprises: sluggish parameter or delay parameter.

Here, under the situation of sluggish parameter, the trigger condition that the report set of revising upgrades specifically comprises: UE finds that the signal quality of the sub-district in report set is not better than the signal quality of the sub-district in the report set in measurement, and is better than a sluggish parameter of the signal quality of the sub-district in the report set.

Under the situation of delay parameter, the trigger condition that the report set of correction upgrades specifically comprises: UE finds that the signal quality of the sub-district in report set is not better than the signal quality of the sub-district in the report set, and keeps a delay parameter in measurement.

Second kind of situation: the mode at the UE reporting measurement reports is: under the situation of the mode that UE periodically reports, carrying out the measurement of corresponding mode and reporting measurement reports specifically comprises for the network element of network side: according to the corresponding report cycle T of mode that periodically reports with UE, UE measures every time T the sub-district in the monitoring collection, and to the reported by network elements measurement report of network side.

Here, the measurement report that reports is: the measurement report of all sub-districts in the report set.

Here, when UE in measurement, when finding that the signal quality of the sub-district in report set is not better than the signal quality of the sub-district in the report set, also comprise before the reporting measurement reports: the not sub-district in report set that signal quality is excellent joins report set, and the sub-district in the ropy report set of respective signal removed from report set, finish the renewal of report set.

Correspondingly, the measurement report that reports has two kinds of specific implementations, first kind: the measurement report that reports is: the measurement report of all sub-districts in the report set after report set upgrades; Second kind: the measurement report of the measurement report of interior all sub-districts of report set after report set upgrades and the sub-district of from report set, removing.

Here, the information in the measurement report comprises at least: the cell id of each sub-district and corresponding to the measurement result of each sub-district.

In sum, the present invention includes following main contents:

As shown in Figure 3, UE finishes when switch the sub-district and measures, and sends the flow process signal of measurement report to network side and network side judgement switching, comprises the steps:

Step 101, RNC be to UE sending measuring control messages, and carry the measurement Control Parameter that relevant UE measures.

Here it is pointed out that to measure in the control messages to comprise following several parameter options that each parameter options determines that one is measured and/or the relevant parameter setting of triggering reporting measurement reports with UE.

Option A: the size of report set, i.e. n value;

Option B: neighbor cell list; Sub-district in the neighbor cell list and UE location current service cell have constituted the monitoring collection;

Option C: measurement parameter, i.e. the content of Ce Lianging, it has reflected the cell signal quality, it can be the RSCP value on the CCPCH channel of this sub-district, or the Interference Signal Code Power value (ISCP) on the TS0 time slot;

The mode of option D:UE reporting measurement reports, the mode of UE reporting measurement reports have three kinds of modes, promptly can report when report set upgrades; Also can require periodically reporting subdistrict measurement report of UE; Can also report by RNC notice UE; These three kinds of modes can and be deposited, and also can only use wherein a kind of; If periodically report mode, RNC also will provide report cycle T in this option so.

Option E: optional supplementary parameter, it is the supplementary parameter relevant with the report set update condition, such as sluggish parameter, delay parameter etc.

Above the respective option can be placed in the measurement control messages and issue, and also can separately measure control messages at some and issue; For a measurement control messages, wherein can include top these options of combination in any.

Step 102, UE receive the measurement control messages, set up report set in inside, and measure monitoring concentrated sub-district.

After UE received and measures control messages, corresponding each parameter options had following operation:

UE at first must receive the measurement control messages that contains neighbor cell list and this even individual parameter options of measurement parameter, clear and definite cell range that it will be measured and measurement content.In the process afterwards, RNC also can change the UE setting by issuing the measurement control messages that has neighbor cell list and measurement parameter again.

If receive the measurement control messages that contains option A, so UE within it portion set up report set, and the sub-district of choosing in n the monitoring collection is put in the report set.Wherein, this n sub-district can be chosen n sub-district arbitrarily arbitrarily in the monitoring collection; Or UE at first measures according to measurement parameter the sub-district in the monitoring collection, chooses n the sub-district of signal quality the best; Perhaps, if the UE ability can not be supported n sub-district measured or can't be set up the report set that contains n sub-district, UE can set up the report set of monitoring the sub-district less than n according to the ability of self so.

If UE receives the measurement control messages of the mode that contains the UE reporting measurement reports, UE can clearly be a reporting measurement reports at once when report set upgrades so, still reporting measurement reports periodically, and perhaps both have both at the same time.

If UE receives the measurement control messages that contains the supplementary parameter option, UE revises the condition that report set upgrades according to these parameters so.

Parameters option in the above-described measurement control messages, RNC can change their value at any time and issue by new measurement control messages, and UE receives that the back renewal is provided with.

Step 103, UE constantly measure according to measurement parameter the sub-district in the monitoring collection; Judge whether measurement result satisfies the trigger condition that report set upgrades, if then execution in step 104; Otherwise, continue the sub-district in the monitoring collection is measured according to measurement parameter.

Step 104, UE upgrade report set, and to the RNC reporting measurement reports.

Here, upgrading report set is: the sub-district more excellent signal quality joins report set, and the relatively poor sub-district of signal quality is removed from report set.

If the mode of reporting measurement reports is to report at once when report set upgrades, so, simultaneously UE can be in RNC sends report set after upgrading the measurement report of all sub-districts and removed sub-district.At least comprise following content in the measurement report: the reason of UE reporting measurement reports is the report set update event, and the cell id of each sub-district and the measurement result of this sub-district are such as the signal quality that receives.

Here it is to be noted: the measurement report that reports comprises the measurement report of all sub-districts in the report set.

Step 105, RNC receive the measurement report that UE reports, and enforcement of judgment execute a judgement is switched.

Here, RNC makes the judgement of whether switching according to the measurement report that the UE that receives reports; If judgement is switched, RNC also will indicate to UE and switch to which sub-district so.

Here it is pointed out that the mode of having supposed the UE reporting measurement reports in the step 103 reports when being the report set renewal at once.If also have option and the report cycle T that periodically reports in the RNC sending measuring message, UE should be after receiving this message so, and execution in step 105a:UE is every the measurement report of time T all sub-districts in RNC sends report set.Afterwards, execution in step 105.

Embodiment 1: the situation of reporting measurement reports immediately when report set upgrades.As shown in Figure 4, in the present embodiment, the information interaction between RNC and the UE may further comprise the steps:

Step 201, RNC issue one to UE and measure control messages.

Here, have following parameter item in this measurement control messages: n value, neighbor cell list, measurement parameter are the RSCP values on the CCPCH channel of sub-district, and the trigger condition of reporting measurement reports reports when being the report set renewal.

Step 202, UE set up report set after receiving this control messages.
