Embodiment

Below by drawings and Examples, technical scheme of the present invention is described in further detail.

The core concept of the embodiment of the present invention is, base station (for example, eNodeB) by system information block (System Information Block, SIB) position of the group paging message that the broadcast sending will send to UE indication base station in MBSFN subframe, make subscriber equipment can in MBSFN subframe, receive group paging message, thereby realize the transmission of group paging message in MBSFN subframe.

Group paging based on eMBMS system mechanism, and the sending method of group paging message, can realize group fast and set up, and lag and enter, and auxiliary group district management simultaneously; Below describe several paging mechanisms, comprise the content of group, trigger condition, transmission times, the operation of terminal, the flow process that paging is initiated etc., wherein group paging message can be for initial call, and lags and enter.

Figure 1A is that a kind of trigger condition is the flow chart of the fixed area group paging foundation of initial call, in group paging message, can be including but not limited to: type of call, the ID of group, traffic ID, speaker ID, speaker's priority, group's uplink state (for example, whether idle), group's state (for example, set up/finish) etc.Type of call can be, fixed area (fixed area) group calling, or offset area (shifted area) group calling.

1, Mobility Management Entity (Mobility Management Entity, MME) is initiated group call to multicast coordination entity (multicast coordinating entity, MCE);

2, MCE notifies corresponding eNB(eNodeB), in the fixed cells of fixed area regulation, initiate group call;

3, eNB is on the channel of eating dishes without rice or wine, and sends group paging message (for example, comprising type of call, the ID of group, or traffic ID etc.), sends group service channel Indication message and corresponding group service simultaneously; Certainly, at this moment group service may also not have arrival, but has set up downlink business pipeline; Wherein, the transmission cycle that group paging is little is T1, duration t1;

4, UE listens to group paging message, according to group's group paging message, determines whether to receive this group service;

If 5 UE determine to receive group service, and monitor group service channel Indication message, wherein, the UE that Radio Resource is controlled idle condition (RRC_IDLE) can not feed back;

6, UE listens to after group service channel Indication message, starts to receive group service;

7, eNB after the time, stops sending group paging message at t1.

Figure 1B is that a kind of trigger condition is the flow chart of the offset area group paging foundation of initial call, as seen from the figure:

1, MME initiates group call to MCE;

2, MCE notifies corresponding eNB, in the community relating at shifted area, initiate group call, the community that comprises the UE place of Radio Resource control connection state (RRC_CONNECT), and the tracking area of the UE of RRC_IDLE state (tracking area, TA);

3, eNB is on the channel of eating dishes without rice or wine, and sends group paging message (for example, comprising type of call, the ID of group, or traffic ID etc.), and wherein the transmission cycle of group paging message is T2, and the duration is t2; Do not send immediately afterwards group service Indication message and corresponding business datum, that is to say and do not set up immediately descending pipeline;

4, UE listens to group paging message, according to group paging message, determines whether to receive this group service;

If 5 UE determine to receive group service, UE, in whole group-calling process, must keep RRC_CONNECT state so, and originally the UE in RRC_IDLE state must make feedback, allows MME learn UE community of living in;

RRC_IDLE state UE initiatively enters RRC_CONNECT state, allows MME learn its community of living in.In addition,, when shifted area, UE, in whole group-calling process, must keep RRC_CONNECT state, allows MME know at any time UE community of living in;

In addition, base station also can send the PMCH numbering of group paging message with UE agreement, for example, in the mbms-Session0 of each dispatching cycle of PMCH0, send, only for for example, can arrange other PMCH or mbms-Session herein, the embodiment of the present invention is not done any restriction yet.

In addition, described SIB can also comprise paging cycle indication information, this paging cycle indication information can be for example pagingMCHCoeff, pagingMCHCoeff represents paging cycle and Multicast Channel (multicast channel, MCH) the multiple relation between dispatching cycle, such as pagingMCHCoeff, can be 1,2,3 or 4 etc., beep-page message be 1,2,3 or 4 times of MCH dispatching cycle.Certainly these multiples, only for for example, are not that in specific implementation, those skilled in the art can arrange this multiple according to actual needs for limiting the present embodiment.

Base station can be identified for carrying the concrete mbms-Session of group paging message according to the LCID of paging-mbms-Session-LCID indication in parameter, base station also can be arranged with UE, by the mode of direct regulation, set transmission cycle and mbms-Session logical channel number or the numbering of group paging message.

For example, in MBSFN-AreaInfo-r9, increase the numbering that paging-mbms-Session-index indicates mbms-Session.

For another example, regulation group paging message is in each dispatching cycle of each PMCH, LCID is 1 upper transmission of mbms-Session, or be defined in each dispatching cycle of each PMCH, the upper transmission of mbms-Session0, then or be defined in each dispatching cycle of PMCH0, the upper transmission of mbms-Session0, only for for example, can arrange other PMCH or mbms-Session herein, the embodiment of the present invention is not done any restriction yet.

UE, in the SIB receiving, reads parameter p agingPMCH, paging-mbms-Session-LCID, determines the mbms-Session that has sent group paging message, then from relevant position, read MCCH, obtain PMCH configuration information, finally, by configuration information, read above-mentioned mbms-Session.In addition, in SIB, can also comprise paging cycle indication information, for example pagingMCHCoeff; So, UE can read this paging cycle indication information, determines the transmission cycle of group paging message.In addition, in SIB, can also comprise multicast control channel (MCCH) positional information or modulation coding mode indication information, so, UE just can be known MCCH positional information or modulation coding mode (MCS, Modulation Coding Scheme), thereby find the position of group paging message, and the group paging message of decoding.

Generally, in this execution mode, the resource location information in described SIB comprises the Physical Multicast Channel PMCH numbering for carrying described group paging message, the logical channel number LCID of mbms-Session; In addition, can also comprise one or more in following information: paging cycle indication information, MCCH positional information and modulation coding mode indication information.

In mbms-Session in Physical Multicast Channel PMCH corresponding to the described resource location information that carries at described SIB base station, to described UE, send group paging message.

In another embodiment, broadcast the subframe position of group paging message in SIB base station, these subframes are as multiplexed sub frame, carry multicast service channel (Multicast traffic Channel simultaneously, MTCH) and the content of multicast paging channel (Multicast Paging Chanel, MPCH), according to logical channel number, distinguish, for carrying the logic channel of group paging message, be MPCH.

Concrete, the resource location information of group paging message is broadcasted in base station in SIB, including but not limited to following information: radio frames deviation post, subframe position and the logical channel number LCID that carries described group paging message.

Wherein, paging-Offset parameter has been determined the radio frames deviation post that group paging message sends, and namely in concrete which radio frames in each wireless frame period, transmits group's beep-page message.

Paging-sf-AllocInfo parameter has been determined the MBSFN subframe position that group paging message sends, and for example, can be that length is 6 bit-map,, in 10 subframes of a radio frames, under FDD, maximum 6 MBSFN subframes that can be configured to send group paging message; Under TDD, maximum 5 can be configured to send group paging message MBSFN subframe, now, only use front 5 bits of these 6 bits, and get rid of sub-frame of uplink.In Frequency Division Duplexing (FDD) (frequency-division duplex, FDD), this 6 bit represents subframe 1,2,3,6,7,8 successively, and in time division duplex (time-division duplex, TDD), front 5 bits represent subframe 3,4,7,8,9 successively.With ' 1 ', represent to send group paging message in this MBSFN subframe, with " 0 ", represent in this MBSFN subframe, not send group paging message.Certainly the present embodiment is not done any restriction, can represent that this MBSFN subframe has sent group paging message with " 0 " yet, with " 1 ", represents in this MBSFN subframe, not send group paging message.Fig. 5 A is the subframe schematic diagram that can be configured to MBSFN subframe in fdd mode, and visible 1,2,3,6,7,8 all can be configured to MBSFN subframe, and therefore 1,2,3,6,7,8 subframes can be configured to the subframe that base station sends group paging message.

Fig. 5 B is the subframe schematic diagram that can be configured to MBSFN subframe under tdd mode, according to different up-downgoing proportionings, can be configured to MBSFN subframe is that descending sub frame may be

only subframe

3,4,7,8,9, the MBSFN subframe that therefore can be sent group paging message by base station can only be also

subframe

3,4,7,8,9, now, last bit in paging-sf-AllocInfo parameter is idle invalid.

In addition, above resource location information can also comprise paging cycle, has determined the transmission cycle of group paging message, for example, and paging-RepetitionPeriod.

Due in this embodiment, that adopt is media access control layer (Medium Access Control, MAC) multiplexing mode, namely in the MBSFN of physical layer subframe, carry the business information of Different Logic channel simultaneously, therefore need to be identified for carrying according to LCID the logic channel of group paging message.For carrying the logic channel of group paging message, can specify by the parameter in SIB so, or base station is direct and the mode of terminal agreement.

If be parameter appointment by SIB for carrying the logic channel of group paging message, need in SIB, set LCID parameter field; And if in the mode of agreement, base station sends group paging message according to the MBSFN sub-frame configuration of appointment, LCID can directly be defined as 1.If MPCH has taken No. LCID 1, the MTCH in so same PMCH just can not take No. LCID 1 again, and if there is group paging, it is for No. LCID 1 mbms-Session that MTCH does not take; When not there is not group paging, the mbms-Session in MTCH just can take No. LCID 1.

Different with the MCS in original subframe for fear of MCS selection, cause and original eMBMS contradiction.Base station is when being group paging message coding, and the MCS of beep-page message is chosen as, and when MPCH and MCCH are when same subframe (that is, multiplexing same subframe), adopts the MCS coding with MCCH; When MPCH and MCCH be not when same subframe (that is, not multiplexing same subframe), adopt the MCS coding of the PMCH that the Multicast Channel MCH of this MPCH of carrying is corresponding.If MPCH and MCH schedule information (MCH scheduling information, MSI) in same subframe, adopt the MCS coding of MCCH so.The priority orders that base station sends is that the priority of MPCH is defined as and is less than MCCH, is greater than MTCH; Namely, when MTCH, MPCH, MCCH data occur simultaneously, MCCH is first transmitted in base station, is then MPCH, is finally MTCH.

When realizing, paging-RepetitionPeriod, paging-Offset and paging-sf-AllocInfo parameter can be added in MBSFN-AreaInfo-r9, be carried in SIB.

Generally, in this embodiment, the resource location information that base station sends by SIB specifically comprises that base station sends the radio frames deviation post of described group paging message, subframe position and for carrying the logical channel number LCID of group paging message.Please refer to Fig. 6, now, above step 302 comprises: step 601: radio frames corresponding to described radio frames deviation post determined in base station, and for example, radio frames corresponding to described radio frames deviation post determined by paging-Offset in base station;

Step 602: base station is in determined radio frames, determine the described MBSFN subframe that described subframe position is corresponding, for example, the described MBSFN subframe that described subframe position is corresponding, in the determined radio frames of paging-Offset, is determined by paging-sf-AllocInf in base station;

Step 603: in determined MBSFN subframe, determine the logic channel that described LCID is corresponding;

Step 604: send group paging message to described UE on determined logic channel.

The resource location information that base station sends by SIB can also comprise that base station sends the paging cycle of described group paging message, for example, and paging-RepetitionPeriod.Now, in above step S640, according to the definite paging cycle of paging-RepetitionPeriod, on determined logic channel, to described UE, send group paging message.

Please refer to Fig. 7, the flow chart of the another kind of embodiment of a kind of group paging method that it provides for the embodiment of the present invention, in this embodiment, executive agent is UE, as seen from Figure 7, described method comprises:

Step 701, receives the system information block SIB that base station sends, and carries the resource location information of group paging message in described SIB;

Concrete, UE can pass through Broadcast Control Channel (Broadcast Control Channel, BCCH), receives SIB, carries the resource location information that base station sends group paging message in SIB.

Step 702, according to described SIB, obtains the resource location information of described group paging message;

Particularly, UE, after receiving SIB, reads resource location information, and determines according to resource location information the resource location that carries group paging message.

For example, if base station sends in SIB, be the Physical Multicast Channel PMCH numbering for carrying described group paging message, the logical channel number LCID of mbms-Session, UE gets is exactly to carry PMCH numbering in the MBSFN subframe of group paging message.

If what base station sent in SIB is radio frames deviation post, subframe position and the logical channel number that base station sends described group paging message, what UE got is exactly the particular location that carries the MBSFN subframe of group paging message, which MBSFN subframe for example, and on which logic channel, obtain group paging message.

Step 703, according to described resource location information, in MBSFN subframe corresponding to described resource location information, obtains group paging message.

The situation that comprises the LCID of PMCH numbering, mbms-Session corresponding to resource location information, UE can comprise step as shown in Figure 8 according to resource location acquisition of information group paging message:

Step 801:: determine that described PMCH numbers corresponding PMCH, wherein, described PMCH is arranged in described MBSFN subframe;

Step 802: determine mbms-Session corresponding to described LCID in determined PMCH;

Step 803: in determined mbms-Session, obtain described group paging message.

After obtaining group paging message, UE can also decode to group paging message, now needs to know the coded system of group paging message, to carry out correct decoding., therefore, resource location information can also comprise modulation coding mode indication information, thus UE can read modulation coding mode indication information, according to the MCS of this modulation coding mode indication information indication, decodes.

In addition, resource location information can also comprise paging cycle indication information, so that UE can be known the transmission cycle of group paging message, thereby correctly finds the position of group paging message.

Moreover resource location information can also comprise multicast control channel MCCH positional information, UE reads MCCH positional information, then from relevant position, reads MCCH, obtains PMCH configuration information, finally, by configuration information, reads above-mentioned mbms-Session.

Corresponding to resource location information, comprise radio frames deviation post, subframe position and for carrying the situation of LCID of the logic channel of described group paging message, UE can comprise step as shown in Figure 9 according to resource location acquisition of information group paging message:

Step 901: determine radio frames corresponding to described radio frames deviation post;

Step 902: in determined radio frames, determine the described MBSFN subframe that described subframe position is corresponding;

Step 903: in determined MBSFN subframe, determine the logic channel that described LCID is corresponding;

Step 904: in determined logic channel, obtain group paging message.

After obtaining group paging message, UE can also decode to group paging message, now needs to know the coded system of group paging message, to carry out correct decoding.

For example, decoding process can determine according to whether the MPCH of concrete carrying group paging message is identical with MCCH.If the subframe of specifically carrying group paging message is as MPCH and MCCH when same subframe (being multiplexing same subframe), decoding process is with the MCS of MCCH; Otherwise, if the subframe of specifically carrying group paging message as MPCH and MCCH not when same subframe (i.e. not multiplexing same subframe), decoding process is identical with the MCS of the corresponding PMCH of MCH of this MPCH of carrying.

For another example,, if MPCH and MCH schedule information (MCH scheduling information, MSI) are in same subframe (being multiplexing same subframe), decoding process is with the MCS of MCCH; Otherwise decoding process is identical with the MCS of the corresponding PMCH of MCH of this MPCH of carrying.That is to say, if one of MCCH and MSI or all with described for carrying the multiplexing same subframe of MPCH of group paging message, adopt the decoding process that MCCH modulation coding mode is corresponding to decode to described group paging message.If MCCH and MSI all not with described for carrying the multiplexing same subframe of MPCH of group paging message, adopt the modulation coding mode of the PMCH that the MCH of this MPCH of carrying is corresponding to decode to described group paging message.

By the above embodiments, UE receives group paging message in MBSFN subframe, can receive immediately business datum afterwards, does not cause extra time delay, saves the waste of eMBMS interface-free resources.

In addition, group paging message only takies the interface-free resources of eMBMS business, can not produce performance impact to non-eMBMS business, and resource scheduling algorithm does not need further design, and prior art comparison, has reduced development and maintenance cost.

In the embodiment shown in fig. 7, the content that the resource location information of carrying while sending SIB due to base station is carried is different, and the mode of position that UE obtains the resource of carrying group paging message is also different.

In one embodiment, UE reads broadcast and (for example, SIB), obtains group paging message position, or directly stipulate beep-page message position.

UE reads the resource location information in SIB, obtains on which mbms-Session of which PMCH and carries group paging message.For example, in each PMCH, LCID is that 1 mbms-Session is exclusively used in and sends group paging message, the transmission cycle be MCH dispatching cycle pagingMCHCoeff doubly.Also can be only in being the PMCH of even number or odd number, numbering sends.

MBSFN-AreaInfo-r9 has defined MCCH in MBSFN region, and multicast control channel relevant information is broadcasted in system message SIB13.

The parameters such as pagingPMCH and paging-mbms-Session-LCID are added in base station in MBSFN-AreaInfo-r9, wherein, pagingPMCH represents the PMCH numbering in the radio frames at group paging message place, paging-mbms-Session-LCID represents the logical channel number of group paging message place mbms-Session, and pagingMCHCoeff has determined that paging cycle is the MCH multiple of dispatching cycle.

Also can according to and base station between agreement directly stipulate the numbering of mbms-Session, for example, be defined in each dispatching cycle of each PMCH, LCID is 1 upper reception of mbms-Session, or in each dispatching cycle of each PMCH, the upper reception of mbms-Session0, or in each dispatching cycle of PMCH0, the upper reception of mbms-Session0.

In addition, UE also can send the PMCH numbering of group paging message with base station agreement, for example, in the mbms-Session0 of each dispatching cycle of PMCH0, receives.

Afterwards, UE, by the original mechanism of eMBMS, reads mbms-Session, to obtain concrete group paging message.

UE is in SIB, and the parameter p agingPMCH reading in advance, paging-mbms-Session-LCID have specified the mbms-Session that has sent group paging message.

UE determines that by pagingPMCH the PMCH in the MBSFN that receives group paging message numbers, and by pagingMCHCoeff, has determined paging cycle, determines the mbms-Session of carrying group paging message by paging-mbms-Session-LCID.

Listening broadcast message SIB, reads MCCH positional information and MCS simultaneously, then from relevant position, reads MCCH, obtains PMCH configuration information, finally, by configuration information, reads above-mentioned mbms-Session.

Generally, UE, according to described SIB, obtains Physical Multicast Channel PMCH numbering, the logical channel number LCID of mbms-Session and the transmission cycle indication information of described group paging message that base station sends group paging message.

In the mbms-Session of UE in PMCH corresponding to described PMCH, according to the transmission cycle of described group paging message, obtain described group paging message, described mbms-Session is corresponding with described LCID information.

In another execution mode, group paging message sends according to the MBSFN sub-frame configuration of appointment.

1) paging-RepetitionPeriod, the wireless frame period of group paging message, paging cycle namely, group paging message sends meeting in the radio frames of following relation: SFN mod paging-RepetitionPeriod=0;

2) paging-Offset, the radio frames deviation post that group paging message sends, meets SFN mod paging-RepetitionPeriod=paging-Offset;

3) paging-sf-AllocInfo, the subframe position that group paging message sends, is that length is 6 bit-map, for example, ' 1 ' represents to send for group paging message;

4) LCID can directly be defined as 1.

UE, according to described paging cycle paging-RepetitionPeriod and described radio frames deviation post paging-Offset, is identified for sending the radio frames of described group paging message;

According to described subframe position paging-sf-AllocInfo, determine the position of described MBSFN subframe;

According to described LCID, determine the logic channel of the described group paging message of carrying;

Afterwards, in described logic channel, obtain group paging message.

If UE is after receiving the SIB that carries above-mentioned parameter, subframe corresponding to the resource location that gets namely MPCH and MCCH when same subframe, adopt the MCS identical with MCCH to carry out decoding, if MPCH and MSI, in same subframe, also adopt the MCS of MCCH.Otherwise, adopt the identical decoding process decoding of MCS of the PMCH that the MCH of this MPCH of carrying is corresponding.After decoding, the service data unit (Service Data Unit, SDU) that the logic number identical with described LCID is corresponding, when there is no corresponding LCID in MSI be 1 field, this SDU is the SDU of the described group paging message of carrying.

Generally, UE, according to described SIB, obtains the logical channel number LCID that base station sends described group paging message radio frames deviation post, subframe position and mbms-Session.UE, according to the positional information of obtaining, obtains group paging message.
