Embodiment

UE gives network side by the status report that measurement report will be in reception MBMS business in the embodiment of the invention, has realized reporting of MBMS service condition.Network side knows that in view of the above UE is receiving MBMS when professional, in handoff procedure, the professional relevant neighbor cell of MBMS that receives with UE as the Target cell that switches, and is switched to this Target cell with UE, thereby improved the MBMS service transmission continuity.

Referring to Fig. 1, report the main method flow process of MBMS service condition as follows in the present embodiment:

Step 101:UE is subjected to measuring the triggering that reports trigger mechanism, need to determine reporting measurement reports.Measurement reports that trigger mechanism comprises that Event triggered reports, periodic report or Event triggered periodic report.

When step 102:UE was in the state that receives the MBMS business, generation had the measurement report that expression is in first indication information of the state that receives the MBMS business.

Step 103:UE sends to network side with the measurement report that generates.

Realized to receive the status report of MBMS business by above flow process UE and given network side, helped network side and carry out switching controls preferably, referring to following flow process.

Referring to Fig. 2, the main method flow process that switch the sub-district in the present embodiment is as follows:

Step 201: network side obtains first indication information that expression UE is in the state that receives the MBMS business by measurement report.

Step 202: network side when carrying out switch decision, the Target cell that the professional relevant neighbor cell of the MBMS that receives with UE is defined as switching.

Step 203: network side switches to definite Target cell with UE.

Present embodiment has been introduced the UE that receives the MBMS business need receive UE the status report of MBMS business to network side, for the UE that does not receive the MBMS business, uploaded state can not report expression not receive second indication information of the state of MBMS business yet.In addition, for the UE that does not support the MBMS business, do not report the state that whether receives the MBMS business.

The process that reports for UE, it can be the UE indication information that in measurement report, carries the state that whether receives the MBMS business initiatively, also can be that network side sends indication to UE, UE receives the back indication information that carries the state that whether receives the MBMS business in follow-up measurement report of this indication.Introduce in detail below by embodiment.

Referring to Fig. 3, it is as follows that UE initiatively reports the method flow of the state that receives the MBMS business in the present embodiment:

For example, UE be subjected to switch relevant Event triggered after send measurement report.

Step 301:UE is subjected to and switches relevant Event triggered.Promptly reach the condition that the Event triggered measurement reports.

Step 302:UE judges the current MBMS business that whether receiving, if then continue step 303, otherwise continue step 304.

Step 303:UE generates the measurement report that has first indication information.This measurement report also comprises the MBMS business information.Perhaps, UE sends the MBMS business information by Radio Resource control (RRC) message to network side.The MBMS business information comprises the professional relevant information of MBMS service identification etc. and MBMS.

Step 304:UE generates and has the measurement report that expression is not in the 3rd indication information of the state that receives the MBMS business.Perhaps, UE generates the measurement report that does not have first indication information and the 3rd indication information.

Step 305:UE sends to network side with the measurement report that generates.

Step 306: network side receives measurement report and resolves.

If measurement report has first indication information, the flow process below then continuing.If measurement report does not have first indication information, may have the 3rd indication information this moment, perhaps do not carry the 3rd indication information, then can carry out switch decision and carry out the sub-district switching according to prior art, for example, switch for the top-quality neighbor cell of UE selective channel.

Step 307: network side carries out switch decision according to measurement report.If need determining switches, the flow process below then continuing, otherwise process ends.

Step 308: the Target cell that network side is defined as the neighbor cell relevant with the MBMS business of UE reception to switch.For example, the network side Target cell that will be defined as switching with frequently neighbor cell with the UE current service cell.If network side is received the MBMS business information, the Target cell that the neighbor cell of supporting the MBMS business that UE receives can be defined as switching then.Preferable, from the neighbor cell of supporting the MBMS business that UE receives, select with neighbor cell frequently, again from the top-quality neighbor cell of selective channel the neighbor cell frequently.

Step 309: network side switches to definite Target cell with UE.

For example, the UE work at present is in the sub-district 1, and just 1 receives the MBMS business in the sub-district.When UE moved to cell edge, the signal strength signal intensity that has measured sub-district 2 and sub-district 3 will be higher than sub-district 1 so, wherein sub-district 2 and sub-district 1 frequency (as f1) together, sub-district 3 and sub-district 1 alien frequencies (frequency as sub-district 3 is f2).Along with UE leaves sub-district 1, sub-district 2 has been triggered to measure and has been reported (A3 incident), sub-district 3 also to trigger to measure that to report (A4 incident), these measurement event all be that eNB 1 disposes for UE in the sub-district.Because this UE is the UE with MBMS receiving ability, and 1 receiving the MBMS business in the sub-district, this UE gives the correct time on measuring so, can carry first indication information.The type of indication information can be boolean's (boolean) type or enumerate (enumerated{true}) type that this moment, the value of first indication information was " TRUE ".In addition, UE can also report the MBMS business information, as the MBSFN area identification, and MBMS service identification (as session identification, service identification) etc.For reporting that other measurement event trigger, as A1, A2 incident etc., UE can not carry this first indication information.Wherein, Boolean type is applicable to the scene that reports the 3rd indication information, and enumeration type is applicable to and does not report the 3rd indication information when not receiving the MBMS business.

ENB is after receiving first indication information that UE reports, know that the current just sub-district on frequency f1 of this UE receives the MBMS business, eNB is in order to guarantee the MBMS business continuance of this UE so, when judgement is switched, selecting sub-district 2 is Target cell, like this, UE 1 switches to sub-district 2 from the sub-district, just can guarantee the MBMS business continuity (continuity of clean culture simultaneously also is guaranteed).

Referring to Fig. 4, network side indication UE reports the method flow of the state that receives the MBMS business as follows in the present embodiment:

For example, network side indication UE is being subjected to carrying first indication information when switching relevant Event triggered in measurement report.Network side can know when the UE initial access network whether UE supports the MBMS business, perhaps knows from core net whether UE supports the MBMS business.

Step 401: network side sends measurement configuration information to UE, and this measurement configuration information comprises whether request UE feedback is in second indication information of the state that receives the MBMS business.Present embodiment newly-increased IE (information word) in measurement configuration information carries this second indication information.

Step 402:UE is subjected to and switches relevant Event triggered.The incident relevant with switching comprises A3, A4 and the A5 incident of LTERRC protocol definition.

Step 403:UE judges the current MBMS business that whether receiving, if then continue step 404, otherwise continue step 405.

Step 404:UE generates the measurement report that has first indication information.This measurement report also comprises the MBMS business information.Perhaps, UE sends the MBMS business information by Radio Resource control (RRC) message to network side.The MBMS business information comprises the professional relevant information of MBMS service identification (service ID) etc. and MBMS.

Step 405:UE generates and has the measurement report that expression is not in the 3rd indication information of the state that receives the MBMS business.Perhaps, UE generates the measurement report that does not have first indication information and the 3rd indication information.

Step 406:UE sends to network side with the measurement report that generates.

Step 407: network side receives measurement report and resolves.

If measurement report has first indication information, the flow process below then continuing.If measurement report does not have first indication information, may have the 3rd indication information this moment, perhaps do not carry the 3rd indication information, then can carry out switch decision and carry out the sub-district switching according to prior art, for example, switch for the top-quality neighbor cell of UE selective channel.

Step 408: network side carries out switch decision according to measurement report.If need determining switches, the flow process below then continuing, otherwise process ends.

Step 409: the Target cell that network side is defined as the neighbor cell relevant with the MBMS business of UE reception to switch.For example, the network side Target cell that will be defined as switching with frequently neighbor cell with the UE current service cell.If network side is received the MBMS business information, the Target cell that the neighbor cell of supporting the MBMS business that UE receives can be defined as switching then.Preferable, from the neighbor cell of supporting the MBMS business that UE receives, select with neighbor cell frequently, again from the top-quality neighbor cell of selective channel the neighbor cell frequently.

Step 410: network side switches to definite Target cell with UE.

For example, the UE work at present is in the sub-district 1, and just 1 receives the MBMS business in the sub-district, and eNB reports by the UE ability or other processes know that this UE has the MBMS ability.ENB sends measurement configuration information to this UE, and wherein configuration UE reports in the process in follow-up measurement, reports its MBMS accepting state, as IE being configured to " TRUE ", promptly carries second indication information in measurement configuration information.When UE moved to cell edge, the signal strength signal intensity that has measured sub-district 2 and sub-district 3 will be higher than sub-district 1, wherein sub-district 2 and sub-district 1 frequency (as f1) together, sub-district 3 and sub-district 1 alien frequencies (frequency as sub-district 3 is f2).Along with UE leaves sub-district 1, sub-district 2 has been triggered to measure and has been reported (A3 incident), sub-district 3 also to trigger to measure that to report (A4 incident), these measurement event all be that eNB 1 disposes for UE in the sub-district.Because this UE is the UE with MBMS receiving ability, and 1 receiving the MBMS business in the sub-district, this UE gives the correct time on measuring so, can carry first indication information.The type of indication information can be boolean's (boolean) type or enumerate (enumerated{true}) type that this moment, the value of first indication information was " TRUE ".In addition, UE can also report the MBMS business information, as the MBSFN area identification, and MBMS service identification (as session identification, service identification) etc.For reporting that other measurement event trigger, as A1, A2 incident etc., UE can not carry this first indication information.Wherein, Boolean type is applicable to the scene that reports the 3rd indication information, and enumeration type is applicable to and does not report the 3rd indication information when not receiving the MBMS business.

ENB is after receiving first indication information that UE reports, know that the current just sub-district on frequency f1 of this UE receives the MBMS business, eNB is in order to guarantee the MBMS business continuance of this UE so, when judgement is switched, selecting sub-district 2 is Target cell, like this, UE 1 switches to sub-district 2 from the sub-district, just can guarantee the MBMS business continuity (continuity of clean culture simultaneously also is guaranteed).

For the saving signaling expense, reduce the Internet resources that measurement report takies, UE can no longer report this information after reporting inferior first indication information of N (N 〉=1) continuously, no longer report this information at least in default duration.Though this moment, network side was not received first indication information, but still handled according to the situation of receiving first indication information, up to the 3rd indication information of receiving that UE reports, perhaps up to satisfying described duration, perhaps sent measurement configuration information once more up to network side.

In order to improve peak rate, with the LTE system compatible, and make full use of frequency spectrum resource, in R10 (version 10), introduced carrier aggregation (Carrier Aggregation, CA) technology.Carrier aggregation technology can be worked UE simultaneously on a plurality of sub-districts, a sub-district comprises a pair of UL (up link) or DL (down link) member carrier (component carrier, rather than have only the pattern of a sub-district (a cover carrier wave) in LTE system and the wireless communication system before CC).Each member carrier can be continuous in the system of carrier aggregation, also can be discontinuous, the bandwidth between each member carrier can be identical or different, in order to keep the system compatible with LTE, the maximum bandwidth limit of each member carrier is 20MHz, and each CC is a sub-district.In addition, LTE-A (Long Term Evolution of upgrading) system also classifies to the sub-district of carrier aggregation, is divided into Pcell (Primary Cell, main plot) and Scell (Secondary Cell, auxilliary sub-district).Have only a cell to be defined as Pcell among the cell of UE polymerization (sub-district).Other cell except Pcell of UE polymerization is called Scell.

Based on carrier aggregation technology, UE is operated in a plurality of sub-districts simultaneously, therefore when reporting the state that whether receives the MBMS business, need report at a plurality of sub-districts, and the specific implementation process is referring to the following examples.

Referring to Fig. 5, support the UE of CA initiatively to report the method flow of the state that receives the MBMS business as follows in the present embodiment:

Step 501:UE is subjected to and switches relevant Event triggered.

The current MBMS business that whether receiving in each sub-district of step 502:UE judgment task if there is the sub-district receiving the MBMS business, then continues step 503, if there is the sub-district not receive the MBMS business, then continues step 504.

Step 503:UE adds first indication information in measurement report.

Step 504:UE adds the 3rd indication information in measurement report.Perhaps, UE does not carry first indication information and the 3rd indication information of this sub-district in measurement report.

Because UE is operated in a plurality of sub-districts, therefore can in measurement report, increase tabulation, as shown in Table 1 and Table 2 about these a plurality of sub-districts.

Table 1

The sub-district IE value (BOOLEAN type) Attribute Pcell True (first indication information) OPTIONAL (optional) Scell1 True OPTIONAL ...... ...... ...... Scell?n False (the 3rd indication information) OPTIONAL

Table 2

The sub-district IE value (enumerated type) Attribute Pcell True (first indication information) OPTIONAL (optional) Scell?1 True OPTIONAL ...... ...... ...... Scell?n (sky) OPTIONAL

This measurement report also comprises the MBMS business information.Perhaps, UE sends the MBMS business information by Radio Resource control (RRC) message to network side.The MBMS business information comprises the professional relevant information of MBMS service identification etc. and MBMS.

Step 505:UE sends to network side with measurement report.

Step 506: network side receives measurement report and resolves.

Step 507: network side carries out switch decision according to measurement report.If need determining switches, the flow process below then continuing, otherwise process ends.

Step 508: at the sub-district of corresponding first indication information, the Target cell that network side is defined as the neighbor cell relevant with the MBMS business of UE reception to switch.

Step 509: at the sub-district of not corresponding first indication information, network side is determined the Target cell of switching according to prior art.As with certain channel quality preferably neighbor cell be defined as Target cell.

Step 510: network side switches to definite Target cell with UE.Can be that switch simultaneously a plurality of sub-districts this moment.

Referring to Fig. 6, support the UE of CA under the indication of network side, to report the method flow of the state that receives the MBMS business as follows in the present embodiment:

Step 601: network side sends measurement configuration information to UE, and this measurement configuration information comprises second indication information.Network side can ask UE to report all working sub-district whether receiving the MBMS business, also can ask the sub-district of appointment in the UE reporting measurement configuration information whether receiving the MBMS business.

Step 602:UE is subjected to and switches relevant Event triggered.

The current MBMS business that whether receiving in each sub-district of step 603:UE judgment task if there is the sub-district receiving the MBMS business, then continues step 604, if there is the sub-district not receive the MBMS business, then continues step 605.

Step 604:UE adds first indication information in measurement report.

Step 605:UE adds the 3rd indication information in measurement report.Perhaps, UE does not carry first indication information and the 3rd indication information of this sub-district in measurement report.

This measurement report also comprises the MBMS business information.Perhaps, UE sends the MBMS business information by Radio Resource control (RRC) message to network side.The MBMS business information comprises the professional relevant information of MBMS service identification etc. and MBMS.

Step 606:UE sends to network side with measurement report.

Step 607: network side receives measurement report and resolves.

Step 608: network side carries out switch decision according to measurement report.If need determining switches, the flow process below then continuing, otherwise process ends.

Step 609: at the sub-district of corresponding first indication information, the Target cell that network side is defined as the neighbor cell relevant with the MBMS business of UE reception to switch.

Step 610: at the sub-district of not corresponding first indication information, network side is determined the Target cell of switching according to prior art.As with certain channel quality preferably neighbor cell be defined as Target cell.

Step 611: network side switches to definite Target cell with UE.Can be that switch simultaneously a plurality of sub-districts this moment.

For example, UE when pre-polymerization three sub-districts, Pcell is sub-district 1, Scell 1 is sub-district 2, Scell 2 is sub-district 3.Network side knows that in advance this UE has the MBMS ability, and configuration UE only reports its MBMS accepting state on sub-district 1, then receives MBMS when professional on sub-district 1 as UE, carries the professional sign that receives of MBMS in measuring reporting message.The eNB Target cell that judgement is switched according to reporting information is selected to switch with the sub-district that receives the professional identical frequency of MBMS as far as possible.
