Description

MBMS dispatching method, system and device

Technical field

The present invention relates to the network communications technology field, be specifically related to the MBMS technology.

Background technology

MBMS (Multimedia Broadcast Multicast Service, multimedia broadcast-multicast service) can realize that network side simultaneously sends to a plurality of recipients in the network to same multi-medium data.MBMS can greatly save interface-free resources.

LTE (Long Term Evolution, Long Term Evolution) utilizes MBSFN (Multimedia Broadcast multicast service Single Frequency Network, multimedia broadcast-multicast service single frequency network) pattern to transmit MBMS.A MBMS uses a logic channel MTCH (MBMS Traffic Channel, MBMS transmission channel), and many MTCH can be mapped on the MCH (Multicast Channel, multicast channel), and promptly a plurality of MBMS can be mapped on the MCH.In addition, many MCH can be mapped on the physical channel PMCH (Physical Multicast Channel).Can there be one or more MCH a sub-district.

Usually, MBMS transmits with time division way by different subframes with Unicast (clean culture) is professional.The subframe of transmission Unicast business is the Unicast subframe, and the subframe of MBMS transmission is the MBSFN subframe.

In order to make UE receive only the MBSFN subframe of its MBMS that needs,, in the MBMS scheduling process, introduced based on MSAP (MCH sub-frame allocation pattern) and DSI (Dynamic Schedule Infirmation, dynamic scheduling information) to save the power consumption of UE.Present MBMS dispatching method comprises:

Network side is by BCCH (Broadcast Control Channel, Broadcast Control Channel) or MCCH (MBMS Control Channel, the MBMS control channel) send MSAP information (being the periodicity configuration information of MSAP) to UE, MSAP information is used to represent the distribution situation of MBSFN subframe.When there were many MCH a sub-district, MSAP information can be expressed the distribution situation of MBSFN subframe among each MCH.The operation that network side sends MSAP information is MSAP occasion (MSAP opportunity), and the cycle that sends MSAP information can be called the MSAP occasion cycle.In order to make UE can accurately receive the MBSFN subframe of its MBMS that needs, network side is provided with the dynamic dispatching cycle, and each dynamic dispatching cycle sends a dynamic scheduling information, to indicate the subframe position that each MTCH takies in this dynamic dispatching cycle is each MBSFN subframe position, thereby UE can determine the MBSFN subframe position that needs receive according to MSAP information that receives and DSI.Because dynamic dispatching cycle and MSAP occasion cycle equate usually, therefore, the base station sends DSI at the section start in each MSAP occasion cycle usually.

A concrete example of the MBMS scheduling of network side as shown in Figure 1.

Fig. 1 shows three MSAP occasion cycles, and MCH1 all takies 3 subframes (filling the fillet of oblique line) in each MSAP occasion cycle, and these 3 subframe positions in each cycle are identical.Can not take the 3rd subframe (filling the fillet of black) in the 3rd MSAP occasion cycle owing to reasons such as service rate is low cause the business datum of the MBMS on the MCH1, make this subframe become vacant subframe.First subframe transmission that DSI (filling the lattice of the fillet top of oblique line) takies by MCH1 in the MSAP occasion cycle.

In realizing process of the present invention, the inventor finds: UE resolves DSI needs the time, UE can only determine the subframe position at target MCH place according to the MSAP information that network side issues before successfully resolving DSI, and all subframes at receiving target MCH place, thereby make UE may receive its unwanted MBSFN subframe, cause the unnecessary power consumption of UE.

Embodiment

Embodiment one, MBMS dispatching method.The flow process of this method as shown in Figure 2.

Among Fig. 2, S200, at current dynamic dispatching cycle of multicast channel, the dynamic scheduling information in dynamic dispatching cycle sent the subframe that requires before the control end selector was fated.

The subframe that meets the transmission requirement that control end is selected is first predetermined subframe, this first predetermined subframe is the subframe at dynamic scheduling information place, and the condition that first predetermined subframe should meet comprises: N subframe at least at interval between first predetermined subframe and second predetermined subframe, N is the positive integer greater than zero, and the value of N can be resolved the needed time setting of dynamic scheduling information according to subscriber equipment.Because subscriber equipment is resolved the needed time of the order of different-format can be different, therefore, also we can say, the value of N can be according to the transmission formatting of dynamic scheduling information, for example, when dynamic scheduling information used MAC (medium access control) layer control signaling to send, N can be 4; Again for example, when dynamic scheduling information used the RRC message format to send, N should be greater than 4 (for example, the value of N can between 10 to 20).In addition, the position of above-mentioned first predetermined subframe is not after first of current dynamic dispatching cycle is used for the MBSFN subframe of business datum of MBMS transmission, and above-mentioned second predetermined subframe is a MBSFN subframe nearest with first predetermined subframe in the current dynamic dispatching cycle.

The subframe (being above-mentioned first predetermined subframe) that meets the transmission requirement that control end is selected can be: first MBSFN subframe in the current dynamic dispatching cycle, at this moment, N subframe at least at interval between second MBSFN subframe in this first MBSFN subframe and current dynamic dispatching cycle; Also can be: before first MBSFN in the preceding dynamic dispatching cycle and with the current dynamic dispatching cycle in first MBSFN subframe non-MBSFN subframe of N subframe at least at interval; Can also be: in the last dynamic dispatching cycle and the current dynamic dispatching cycle in first MBSFN subframe between the MBSFN subframe of N subframe at least at interval; In addition, can also be: in the last dynamic dispatching cycle and the current dynamic dispatching cycle in first MBSFN subframe between the non-MBSFN subframe of N subframe at least at interval.

The dynamic dispatching cycle among the above-mentioned S200 can be identical with the MSAP occasion cycle, also can be inequality with the MSAP occasion cycle, and, corresponding dynamic scheduling information of each dynamic dispatching cycle, dynamic scheduling information can be at the current dynamic dispatching cycle of a multicast channel, also can be at the current dynamic dispatching cycle of many multicast channels.

Control end is selected meet send the subframe that requires can corresponding dynamic scheduling information, also can corresponding a plurality of dynamic scheduling informations.That is to say that a plurality of dynamic scheduling informations can take same subframe, also can take different subframes.

The subframe that meets the transmission requirement that control end is selected can be the MBSFN subframe, also can be non-MBSFN subframe.Non-MBSFN subframe such as unicast sub etc.

Meeting the subframe that sends requirement is under the situation of MBSFN subframe, if dynamic scheduling information is at the current dynamic dispatching cycle of a multicast channel, then meeting the MBSFN subframe that send to require can be for distributing to the MBSFN subframe that current multicast channel uses, also can be for distributing to the MBSFN subframe that non-current multicast channel uses.Current multicast channel be dynamic scheduling information at multicast channel.

Meeting the subframe that sends requirement is under the situation of non-MBSFN subframe, dynamic scheduling information can pass through PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) or PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) send to subscriber equipment.The multiple specific implementation process that present embodiment can adopt existing PDSCH of utilization or PDCCH to send information sends dynamic scheduling information, and present embodiment does not limit the specific implementation process of utilizing PDSCH or PDCCH to send dynamic scheduling information.

In S200, control end can select to meet the subframe that sends requirement according to predetermined policy.Predetermined policy can be provided with according to the situation of concrete network, no matter what the particular content of predetermined policy is, as long as the subframe of selecting meets the condition of foregoing description.Simply exemplify several selections below and meet the object lesson that sends the subframe that requires.

Example 1, control end obtain between first MBSFN subframe in the current dynamic dispatching cycle and second the MBSFN subframe sub-frame number at interval, and judge that whether this sub-frame number is more than or equal to N, if more than or equal to N, then control end is defined as meeting the subframe that sends requirement with first MBSFN subframe, otherwise, determine not meet the subframe that sends requirement.Do not meeting under the situation that sends the subframe that requires, the subframe transmitting terminal can send dynamic scheduling information according to existing method.

In fact, the predetermined policy in the above-mentioned example 1 is: N subframe at least at interval between first MBSFN subframe in the current dynamic dispatching cycle and second the MBSFN subframe.

Example 2, control end obtain between first MBSFN subframe in the current dynamic dispatching cycle and second the MBSFN subframe sub-frame number at interval, and judge that whether this sub-frame number is more than or equal to N.If more than or equal to N, then control end is defined as meeting the subframe that sends requirement with first MBSFN subframe; Otherwise control end continue to judge in the current dynamic dispatching cycle, before first MBSFN subframe, whether exist and this first MBSFN subframe between the non-MBSFN subframe of N subframe at least at interval.Have so non-MBSFN subframe if judge, then control end is defined as one of them non-MBSFN subframe to meet and sends the subframe that requires, and does not have so non-MBSFN subframe if judge, and then control end determines not meet the subframe that sends requirement.Do not meeting under the situation that sends the subframe that requires, the subframe transmitting terminal can send dynamic scheduling information according to existing method.

In fact, the predetermined policy in the above-mentioned example 2 is: between first MBSFN subframe in the current dynamic dispatching cycle and second the MBSFN subframe at least at interval N subframe and exist in the current dynamic dispatching cycle and first MBSFN subframe between the non-MBSFN subframe of N the subframe in interval at least.

Example 3, control end were selected between first MBSFN subframe in one and current dynamic dispatching cycle the MBSFN subframe of N subframe at least at interval from a last dynamic dispatching cycle, and the MBSFN subframe that this is selected is defined as meeting the subframe that sends requirement.

In fact, the predetermined policy in the above-mentioned example 3 is: in the last dynamic dispatching cycle, with the current dynamic dispatching cycle in first MBSFN subframe N subframe at least at interval.

Example 4, control end obtains between first MBSFN subframe in the current dynamic dispatching cycle and second the MBSFN subframe sub-frame number at interval, and judge that whether this sub-frame number is more than or equal to N, if more than or equal to N, then control end is defined as meeting the subframe that sends requirement with first MBSFN subframe, otherwise, control end continue to judge whether exist in the current dynamic dispatching cycle and first MBSFN subframe between the non-MBSFN subframe of N the subframe in interval at least, there is so non-MBSFN subframe if judge, then control end is defined as meeting the subframe that sends requirement with one of them non-MBSFN subframe, there is not so non-MBSFN subframe if judge, then control end was selected between first MBSFN subframe in one and current dynamic dispatching cycle the non-MBSFN subframe of N subframe at least at interval from a last dynamic dispatching cycle, and the non-MBSFN subframe that this is selected is defined as meeting the subframe that sends requirement.

In fact, the predetermined policy in the above-mentioned example 4 is: between first MBSFN subframe in the current dynamic dispatching cycle and second the MBSFN subframe at least at interval N subframe, exist in the current dynamic dispatching cycle with first MBSFN subframe between at least N the subframe in interval non-MBSFN subframe and in the last dynamic dispatching cycle with the current dynamic dispatching cycle in first MBSFN subframe non-MBSFN subframe of N the subframe in interval at least.

Above-mentioned 4 examples that exemplify can also split other situations that is combined as, for example, above-mentioned example 1 and example 3 can be combined as: control end obtains between first MBSFN subframe in the current dynamic dispatching cycle and second the MBSFN subframe sub-frame number at interval, and judge that whether this sub-frame number is more than or equal to N, if more than or equal to N, then control end is defined as meeting the subframe that sends requirement with first MBSFN subframe, otherwise, control end was selected between first MBSFN subframe in one and current dynamic dispatching cycle the MBSFN subframe of N subframe at least at interval from a last dynamic dispatching cycle, and the MBSFN subframe that this is selected is defined as meeting the subframe that sends requirement.Again for example, after above-mentioned example 2 split again and example 3 be combined as: control end judge whether exist in the current dynamic dispatching cycle and first MBSFN subframe between the non-MBSFN subframe of N subframe at least at interval, there is non-MBSFN subframe if judge, then control end is defined as meeting the subframe that sends requirement with one of them non-MBSFN subframe, there is not non-MBSFN subframe if judge, then control end was selected between first MBSFN subframe in one and current dynamic dispatching cycle the MBSFN subframe of N subframe at least at interval from a last dynamic dispatching cycle, and the MBSFN subframe that this is selected is defined as meeting the subframe that sends requirement.Certainly, control end can also split compound mode by other and form the example that other selections meet the subframe that sends requirement, exemplifies explanation no longer one by one at this.

S210, select meet the subframe that send to require after, control end issues to the subframe transmitting terminal and meets the subframe position information that requires that sends.

S220, subframe transmitting terminal receive the subframe position information that control end issues, and send the dynamic scheduling information in current dynamic dispatching cycle according to this subframe position information.

The process of above-mentioned S200 to S220 is also promptly: control end determines to can be used for sending the subframe position of dynamic scheduling information, and this subframe position information offered the transmitting terminal of dynamic scheduling information, this transmitting terminal sends dynamic scheduling information in the subframe of this subframe position information correspondence.The subframe that can be used for here sends dynamic scheduling information is above-mentioned meeting to send the subframe that requires.Wherein, control end can be mobility controlled entity MCE, or evolution base station eNB, or BM-SC.The transmitting terminal of dynamic scheduling information can be eNB.

Further, the dynamic scheduling information among the S220 can be that the subframe transmitting terminal is according to data configuration to be sent.The dynamic scheduling information that constructs can show as the form of MAC layer control signaling, also can show as the form of RRC message.The content that the dynamic scheduling information that the subframe transmitting terminal sends specifically comprises can have different ways, as long as can express the subframe scheduling situation in the current dynamic dispatching cycle.The object lesson that exemplifies the content that several dynamic scheduling informations comprise of the property of the following describes.

First concrete example is: original position and the business datum of the MBMS sub-frame number that during dynamic dispatching cycle take of the business datum of service identification, MBMS that dynamic scheduling information comprises MBMS in the dynamic dispatching cycle; Second concrete example is: dynamic scheduling information comprises the service identification of MBMS, original position and the end position of business datum in the dynamic dispatching cycle of MBMS; The 3rd concrete example is: dynamic scheduling information comprises the sub-frame number that the business datum of the service identification of MBMS and MBMS takies in the dynamic dispatching cycle; The 4th concrete example is: dynamic scheduling information comprises sub-frame number and the expansion sign that the business datum of service identification, the MBMS of MBMS takies in the dynamic dispatching cycle, the business datum of a MBMS of this expansion sign expression whether with the shared same subframe of the business datum of other MBMS; The 5th concrete example is: dynamic scheduling information comprises the original position of business datum in the dynamic dispatching cycle of service identification and the MBMS of MBMS; The 6th concrete example is: dynamic scheduling information comprises the service identification of MBMS and the end position of business datum in the dynamic dispatching cycle of MBMS; The 7th concrete example is: the service identification of MBMS, the business datum of MBMS end position and the expansion sign in the dynamic dispatching cycle, the business datum of this MBMS of this expansion sign expression whether with the shared subframe of the business datum of other MBMS.

Above-mentioned the 5th example can also optionally comprise: the end position of last MBMS.If above-mentioned the 5th example do not comprise the end position of last MBMS, the PDCCH that the pairing sign of subframe that last that then can be in this dynamic dispatching cycle is used to send the MBSFN business is put into dynamic scheduling information place subframe transmits, to indicate the MBSFN subframe in the current dynamic dispatching cycle and the separation of vacant subframe, thereby indicate the position of the vacant subframe in the current dynamic dispatching cycle, help avoiding the valuable interface-free resources of vacant subframe waste.

Further, the expansion in above-mentioned object lesson sign can be specially: indicate a MBMS business datum last MBSFN subframe whether with the shared same subframe of the business datum of other MBMS; Also can be specially: indicate a MBMS business datum first MBSFN subframe whether with the shared same subframe of the business datum of other MBMS.

For avoiding the waste of interface-free resources, the subframe transmitting terminal can utilize vacant subframe to send non-MBMS data (as unicast service data etc.), after subscriber equipment then can be determined the position that has vacant subframe and vacant subframe according to dynamic scheduling information and MSAP information, use the non-MBMS data in the vacant subframe of pilot reception of normal CP and cell range.The subframe transmitting terminal can be determined needs according to the information of user equipment to report and utilize vacant subframe which subscriber equipment to send non-MBMS data to.The information of user equipment to report can comprise that subscriber equipment receives the information of which MBMS.

From the description of the foregoing description one as can be known, control end is by selecting to meet the subframe that sends requirement for dynamic scheduling information, make subscriber equipment can finish the reception of dynamic scheduling information earlier and know its information content, carry out the selectivity reception of MBSFN subframe then according to this information content, after can guaranteeing that subscriber equipment is in time known the position of the MBSFN subframe that it needs, only receive at its MBSFN subframe that needs, thereby the phenomenon of having avoided subscriber equipment that unwanted MBSFN subframe is received, the power consumption of having saved UE.Further, the subframe transmitting terminal sends the MBSFN subframe by utilizing vacant subframe, subscriber equipment is judged had vacant subframe, and utilize unicast service data in the vacant subframe of pilot reception of predetermined CP and cell range, can make full use of vacant subframe, avoid the wasting phenomenon of valuable interface-free resources.

In other embodiments of the invention, control end can be determined the transmission position of dynamic scheduling information earlier, will send the transmitting terminal that position informing is a dynamic scheduling information then.Wherein, N subframe after the transmission position of dynamic scheduling information do not comprise this dynamic scheduling information corresponding M BMS business datum, one or more subframe after the N subframe after sending the position can comprise this dynamic scheduling information corresponding M BMS business datum, wherein, N is a positive integer, can know that according to subscriber equipment the needed time of content of dynamic scheduling information is provided with by control end, for example N is greater than 4, and less than 200 integer, certainly, the span of N may be smaller, for example the integer between 4 to 8.Need to prove, if the transmission position of dynamic scheduling information is in the dynamic dispatching cycle before the subframe that comprises this dynamic scheduling information corresponding M BMS data, then the N of a between subframe may comprise other existing dynamic scheduling information corresponding M BMS data, also may comprise non-MBMS business datum.Here existing dynamic scheduling information is meant that control end is by the dynamic scheduling information before the current dynamic scheduling information of the definite position of said process.

Embodiment two, under the situation of the corresponding MCH of dynamic scheduling information, utilize the MBMS dispatching method of first MBSFN subframe transmission dynamic scheduling information in the current dynamic dispatching cycle.

Network side can be considered the value of N MBSFN subframe distribution and dynamic dispatching being set during the cycle, for example, makes in the dynamic dispatching cycle distance between second the MBSFN subframe and first MBSFN subframe more than or equal to N subframe.Like this, dynamic scheduling information can be by first MBSFN subframe transmission in the dynamic dispatching cycle.

A concrete example is: the value of N is 3, if include three MBSFN subframes in the radio frames, be #3 subframe, #7 subframe and #8 subframe, and the dynamic dispatching cycle from this radio frames, then can to select the #3 subframe be to meet the subframe that send to require to control end.In this case, the #3 subframe is used to transmit dynamic scheduling information, can also be used for the business datum of MBMS transmission simultaneously, and #7 subframe and #8 subframe are used for the business datum of MBMS transmission.

Under the MCCH repetition period situation identical with the original position in dynamic dispatching cycle, if MCCH message need be by first MBSFN subframe transmission in the MCCH repetition period, then the subframe at MCCH message place is the subframe (the #3 subframe in the present embodiment) at dynamic dispatching cycle place, at this moment, can the make an appointment sending order of MCCH message and DSI, for example, the DSI that makes an appointment sends earlier, sends after the MCCH message.If agreement MCCH message sends earlier, and MCCH message is big (the shared subframe of MCCH message is greater than 1), second MBSFN subframe (the #7 subframe in the present embodiment) that then can cause DSI message to be postponed till in the current dynamic dispatching cycle sends, at this moment, second MBSFN subframe is first MBSFN subframe that is used for the business datum of MBMS transmission in the current dynamic dispatching cycle.In N subframe of second MBSFN subframe back, have under the situation of MBSFN subframe (the #8 subframe in the present embodiment) appearance, may cause the UE power consumption to increase slightly.

Embodiment three, under the situation of the corresponding MCH of dynamic scheduling information, utilize the MBMS dispatching method of non-MBSFN subframe (unicast sub) the transmission dynamic scheduling information in the current dynamic dispatching cycle.

Second MBSFN subframe in the current dynamic dispatching cycle and the distance between first MBSFN subframe less than the sub-frame number of N subframe and first MBSFN subframe front in the current dynamic dispatching cycle greater than N, then control end can be defined as first non-MBSFN subframe in the current dynamic dispatching cycle to meet to a subframe in i the non-MBSFN subframe and send the subframe that requires, and the i here non-MBSFN subframe is meant: and have the non-MBSFN subframe of N subframe between first MBSFN subframe.In this case, the subframe transmitting terminal can utilize DSCH Downlink Shared Channel PDSCH, send DSI by non-MBSFN subframe.Distance between above-mentioned second MBSFN subframe and first MBSFN subframe is promptly: at interval number of sub frames between second MBSFN subframe and first MBSFN subframe.

Utilize PDSCH to send under the situation of DSI by non-MBSFN subframe at network side, DSI can use special-purpose RNTI addressing, this special-purpose RNTI can be the RNTI of agreement regulation, also can be network side is informed UE in advance by MCCH RNTI, UE utilizes RNTI to carry out addressing with the position of acquisition DSI or the position range of DSI, UE detects PDCCH in DSI position or subframe that position range identified, to obtain DSI information.In addition, network side also can use MCCH that UE is informed in the position of DSI or the position range of DSI, UE detects PDCCH, to obtain DSI information in DSI position or subframe that position range identified behind the position of knowing DSI by MCCH or DSI position range.In addition, the position of DSI or the position range of DSI if agreement has been made an appointment, UE can detect PDCCH in the subframe that identifies in the relevant position of making an appointment according to agreement, to obtain DSI information.

Utilize non-MBSFN subframe to be: three MBSFN subframes are arranged in the radio frames by the concrete example that Physical Downlink Shared Channel PDSCH sends dynamic scheduling information, be respectively #6 subframe, #7 subframe and #8 subframe, the dynamic dispatching cycle is from this radio frames, under the situation of N=4, network side sends DSI in #0 subframe or #1 subframe by PDSCH, and the RNTI of DSI is the RNTI that makes an appointment.

UE utilizes DSI to carry out the decision operation whether current dispatching cycle has sent the business datum of its MBMS that needs and whether received data in the MBSFN subframe after receiving DSI.

Embodiment four, under the situation of the corresponding MCH of dynamic scheduling information, utilized the MBMS dispatching method of the MBSFN subframe transmission dynamic scheduling information in last dynamic dispatching cycle in current dynamic dispatching cycle.

According to the subframe distribution situation of MBSFN, network side can utilize the current dynamic dispatching cycle on certain MBSFN subframe (as last MBSFN subframe) in dynamic dispatching cycle transmit dynamic scheduling information.Certain MBSFN subframe in the last dynamic dispatching cycle can be the subframe that is taken by the business datum of MBMS, also can be vacant subframe.UE behind the DSI in dynamic dispatching cycle, utilizes this DSI to select the business datum of its MBMS that need receive in the next dynamic dispatching cycle on receiving.

A concrete example as shown in Figure 3.Long narrow of grey among Fig. 3 is the MBSFN subframe for the subframe that MCH1 takies.First dynamic dispatching cycle was a last dynamic dispatching cycle, and the second dynamic dispatching cycle was the current dynamic dispatching cycle, and the DSI of current dispatching cycle sent by the subframe that last MCH1 in the last dynamic dispatching cycle takies.

Embodiment five, under the situation of the corresponding MCH of dynamic scheduling information, utilized the MBMS dispatching method of the non-MBSFN subframe transmission dynamic scheduling information in last dynamic dispatching cycle in current dynamic dispatching cycle.4 couples of embodiment five describe below in conjunction with accompanying drawing.

Long narrow of grey among Fig. 4 is the MBSFN subframe for the subframe that MCH1 takies.Long narrow of white is the Unicast subframe.First dynamic dispatching cycle was a last dynamic dispatching cycle, and the second dynamic dispatching cycle was the current dynamic dispatching cycle.According to MBSFN subframe distribution pattern and dynamic dispatching cycle, network side is determined first MBSFN subframe in the current dynamic dispatching cycle at the section start in current dynamic dispatching cycle, the Unicast number of sub frames that is first MBSFN subframe front is not more than N, then network side can be chosen in certain Unicast subframe in the dynamic dispatching cycle as the subframe at the DSI place in current dynamic dispatching cycle, and transmits DSI by PDSCH.Unicast subframe that network side is selected and the interval between first MBSFN subframe in current dynamic dispatching cycle are more than or equal to N subframe.The specific implementation process of network side use PDSCH transmission DSI can be as the description among the above-mentioned embodiment, in this no longer repeat specification.

UE behind the DSI in dynamic dispatching cycle, utilizes this DSI to select the business datum of its MBMS that need receive in the next dynamic dispatching cycle on receiving.

In the following embodiments, exemplify the concrete structure of several DSI, the following examples can be applied among above-described each embodiment.

The original position of the business datum of embodiment six, the service identification that includes MBMS, MBMS in the dynamic dispatching cycle and the DSI of the sub-frame number that in the dynamic dispatching cycle, takies of the business datum of MBMS.

Subframe transmitting terminal such as base station are according to data configuration DSI to be sent, and the base station can use MAC layer control signaling to transmit DSI.At each MBMS, DSI comprises following three partial informations:

1, the service identification of the service identification of MBMS: MBMS can be at MBMS of whole M BSFA zone unique identification, as utilizes TMGI to represent the service identification of MBMS; The service identification of MBMS also can identify a MBMS in a MCH scope, as utilizes logic channel ID to represent the service identification of MBMS.

2, the original position of the business datum of MBMS in the dynamic dispatching cycle: all subframe scope inside countings that original position can comprise in the dynamic dispatching cycle, also can be only in the inside counting of MBSFN subframe scope, can also be only a subframe scope inside counting that MCH is shared.

UE can utilize the DSI shown in the table 7 to determine the subframe that each MBMS is shared, simultaneously, can also judge whether the MBSFN subframe in the current dynamic dispatching cycle is all taken by MBMS, if there is not absorb, then unappropriated subframe is vacant subframe.UE can use the pilot tone of normal CP and cell range to receive non-MBMS data such as Unicast business datum etc. at these vacant subframe places.

The foregoing description 6 to 12 all is in the dynamic dispatching cycle, and at each MCH, sending a dynamic scheduling information is that example describes.If interior a plurality of MBSFN sub-frame allocation of dynamic dispatching cycle use for a plurality of MCH, then can construct a unified dynamic scheduling information, in this unified dynamic scheduling information, indicate the subframe position information of all MBMS that send in the current dynamic dispatching cycle, no matter these MBMS are mapped to one or more MCH.In this case, all subframe scope inside countings that original position among the DSI in the foregoing description 6 to 12 and end position can comprise in the dynamic dispatching cycle, also can be only in the inside counting of MBSFN subframe scope, but can not be in the shared subframe scope inside counting of certain MCH.

An object lesson at a unified dynamic scheduling information of above-mentioned structure describes in embodiment 13 below.

The DSI of the sub-frame number that the DSI of the original position of business datum in the dynamic dispatching cycle of embodiment 13, the service identification that includes MBMS, MBMS and the business datum of MBMS took in the dynamic dispatching cycle.

Fig. 7 shows a dynamic dispatching cycle, include six MBSFN subframes in this dynamic dispatching cycle, be respectively #1 subframe (first fill oblique grid long narrow), #2 subframe (first fill grid square long narrow), (the first half is filled oblique line to #3, long narrow of the latter half filling point) subframe, #6 subframe (all long narrow of filling points), #7 subframe (the first half filling point, packless long narrow of the latter half) and #8 subframe (filling black long narrow).

Above-mentioned these 6 MBSFN subframes are used separately as two MCH, simultaneously, have four MBMS to transmit in this dynamic dispatching cycle, and wherein, MTCH1 and MTCH2 are mapped to MCH A, and MTCH3 and MTCH 4 are mapped to MCH B.MCH A uses #1 subframe and #2 subframe, and MCHB uses #3 subframe, #6 subframe and #7 subframe, and wherein, MTCH 1 takies the #1 subframe, and MTCH 2 takies the #2 subframe, and MTCH 3 takies the #3 subframe, and MTCH 4 takies #3 subframe, #6 subframe and #7 subframe; The #8 subframe is vacant subframe.

The DSI in described dynamic dispatching cycle of Fig. 7 can be as shown in table 6.

Table 6

UE can utilize the DSI shown in the table 6 to determine the subframe that each MBMS is shared, simultaneously, whether can also the MBSFN subframe in the 7 described dynamic dispatching cycles of process decision chart all be taken by MBMS, if there is not absorb, then unappropriated subframe is vacant subframe.UE can use the pilot tone of normal CP and cell range to receive the Unicast business at these vacant subframe places.

At the various embodiments described above of particular note, if make an appointment (as the agreement regulation etc.) some subframe in radio frames can not be used as the MBSFN subframe, some subframe numberings of then putting down in writing in the various embodiments described above need to do corresponding the adjustment, for example, if #0 subframe, #4 subframe, #5 subframe and #9 subframe in the radio frames need be used as the paging subframe, and can not be used as the MBSFN subframe, then original position in the foregoing description and end position can not be the position of #0 subframe, #4 subframe, #5 subframe and #9 subframe.In addition, do not have in various embodiments of the present invention under the situation of specified otherwise, first MBSFN subframe among each embodiment is that first is used for the MBSFN subframe of the business datum of MBMS transmission in the current dynamic dispatching cycle.

Need to prove, in the DSI that above-mentioned a plurality of embodiment provide, include the MBMS service identification.In fact, DSI can be not explicit yet comprises the MBMS service identification.For example, network side and the UE work flow among the DSI of making an appointment is identical with work flow among the MCCH such as the work flow among the DSI.And for example, DSI comprises bit map, is used to identify the dynamic scheduling information that includes which MBMS business in this DSI, and bitmap lengths equates with number of services among the MCCH, perhaps equates with number of services on the MCH.Each bit is represented a business in the bitmap, and the work flow that bitmap is represented is identical with work flow among the MCCH." 0 " in the bitmap represents that this dynamic scheduling information does not have corresponding professional schedule information, and " 1 " represents that this dynamic scheduling information has corresponding professional schedule information.UE determines service identification concrete among the DSI according to this bit map.

Embodiment 14, the dispatching method that provides with the foregoing description are corresponding, and present embodiment provides the business datum acquisition methods of a kind of MBMS.

Wherein, UE can obtain the positional information of dynamic scheduling information earlier, and receives dynamic scheduling information according to this positional information, and this process can repeat no more referring to the prior art scheme herein.

If the dynamic scheduling information that UE receives is arranged in dynamic dispatching cycle (can be described as UE and use the dynamic dispatching cycle that this dynamic scheduling information the receives data) subframe before at its corresponding MBMS business datum place, then UE arrives the dynamic dispatching of this dynamic scheduling information correspondence during the cycle, use this dynamic scheduling information again, promptly receive the business datum of MBMS according to its instruction content, wherein, first in the dynamic dispatching cycle that this dynamic scheduling information is corresponding with it is used to transmit N the subframe of being separated by at least between the subframe of business datum of MBMS.

If the dynamic scheduling information that UE receives is positioned at the dynamic dispatching cycle at its corresponding MBMS business datum place, after then UE receives this dynamic scheduling information in this dynamic dispatching cycle, promptly know its instruction content, and receive the business datum of MBMS according to this instruction content.Wherein, this dynamic scheduling information and thereafter the next one subframe that is used to transmit the business datum of MBMS N the subframe of being separated by at least.

Furthermore, after UE obtains dynamic scheduling information, in N subframe thereafter, can not receive the MBSFN subframe of the business datum that is used for MBMS transmission in dynamic dispatching cycle of this dynamic scheduling information correspondence.Also promptly: UE reads dynamic scheduling information earlier, and knows the content of its indication.Know at UE before the content of dynamic scheduling information, UE can blindly not receive and can't determine whether those subframes that need receive for self, and have only UE after knowing dynamic scheduling information, just receive the MBSFN subframe that is used for transferring MBMS service data according to this dynamic scheduling information.

Concrete example a: UE is known the content of dynamic scheduling information, and this dynamic scheduling information indicates certain or some second default subframes to comprise this dynamic scheduling information corresponding M BMS business datum; Then, UE receives all or part of MBMS business datum in the second default subframe.Wherein, the one or more subframes after N the subframe after the subframe that the second default subframe is this dynamic scheduling information place, the N here is a positive integer.Further, dynamic scheduling information corresponding M BMS business datum is meant the data of the MBMS business of this dynamic scheduling information indication scheduling in being somebody's turn to do for example.Optionally, the transmission position of this dynamic scheduling information and the second default subframe are in the same dynamic dispatching cycle, and perhaps, the transmission position of dynamic scheduling information is in the previous dynamic dispatching cycle of the second default subframe.Certainly, when second preset subframe more than one, a plurality of second default subframe was in the same dynamic dispatching cycle.In this example, UE knows that the content of dynamic scheduling information can comprise: UE receives the first default subframe that comprises dynamic scheduling information, and finishes the parsing to this dynamic scheduling information.

Further, UE can also determine whether to exist vacant subframe according to dynamic scheduling information and the MSAP of knowing information, if, UE can check whether (monitor) has the non-MBMS business datum of issuing oneself in vacant subframe, concrete, UE can use the non-MBMS business datum in the vacant subframe of the pilot reception of normal CP and cell range.

Use present embodiment, subscriber equipment can in time be known the position of the MBSFN subframe that it needs, only receive then at its MBSFN subframe that needs, thus the phenomenon of having avoided subscriber equipment that unwanted MBSFN subframe is received, the power consumption of having saved UE.Further, data sending terminal can utilize vacant subframe to send data, thereby UE is judging when having vacant subframe, and utilize unicast service data in the vacant subframe of pilot reception of predetermined CP and cell range, can make full use of vacant subframe, avoid the wasting phenomenon of valuable interface-free resources.

Embodiment 15, MBMS dispatching patcher.The structure of this system as shown in Figure 8.

System among Fig. 8 comprises: control end 800 and at least one subframe transmitting terminal 810.Control end 800 can be Centroid in the system etc., and subframe transmitting terminal 810 can be base station in the system etc.

Control end 800 is used for the current dynamic dispatching cycle at multicast channel, and the dynamic scheduling information in dynamic dispatching cycle sent the subframe that requires before selector was fated, and issued the subframe position information that meets the transmission requirement to subframe transmitting terminal 810.

The subframe that meets the transmission requirement that control end 800 is selected is first predetermined subframe, this first predetermined subframe is the subframe at dynamic scheduling information place, and the condition that first predetermined subframe should meet comprises: N subframe at least at interval between first predetermined subframe and second predetermined subframe, N is the positive integer greater than zero, and the value of N can be resolved the needed time setting of dynamic scheduling information according to subscriber equipment.Because subscriber equipment is resolved the needed time of the order of different-format can be different, therefore, also we can say, the value of N can be according to the transmission formatting of dynamic scheduling information, for example, when dynamic scheduling information used MAC layer control signaling to send, N can be 4; Again for example, when dynamic scheduling information used the RRC message format to send, N should be greater than 4 (for example, the value of N can between 10 to 20).In addition, the position of above-mentioned first predetermined subframe is not after first of current dynamic dispatching cycle is used for the MBSFN subframe of business datum of MBMS transmission, and above-mentioned second predetermined subframe is a MBSFN subframe nearest with first predetermined subframe in the current dynamic dispatching cycle.The dynamic dispatching cycle here can be identical with the MSAPoccasion cycle, also can be inequality with the MSAP occasion cycle, and, corresponding dynamic scheduling information of each dynamic dispatching cycle, dynamic scheduling information can be at the current dynamic dispatching cycle of a multicast channel, also can be at the current dynamic dispatching cycle of many multicast channels.

Control end 800 is selected meet send the subframe that requires can corresponding dynamic scheduling information, also can corresponding a plurality of dynamic scheduling informations.That is to say that a plurality of dynamic scheduling informations can take same subframe, also can take different subframes.

The subframe that meets the transmission requirement that control end 800 is selected can be the MBSFN subframe, also can be non-MBSFN subframe.Non-MBSFN subframe such as unicast sub etc.

Control end 800 can select to meet the subframe that sends requirement according to predetermined policy.Predetermined policy can be provided with according to the situation of concrete network, no matter what the particular content of predetermined policy is, as long as the subframe that control end 800 is selected meets the condition of foregoing description.Control end 800 is selected to meet the object lesson of the subframe that sends requirement such as the description among the above-mentioned method embodiment, in this no longer repeat specification.

Subframe transmitting terminal 810, be used to receive the subframe position information that meets the transmission requirement that control end 800 issues, and send the dynamic scheduling information in current dynamic dispatching cycle according to the subframe position information that receives, promptly dynamic scheduling information is dispatched in the subframe, and sends to UE according to subframe position information.

Meeting the subframe that sends requirement is under the situation of non-MBSFN subframe, and subframe transmitting terminal 810 can send DSI to UE by PDSCH or PDCCH.The multiple specific implementation process that subframe transmitting terminal 810 can adopt existing PDSCH of utilization or PDCCH to send information sends dynamic scheduling information, and present embodiment does not limit subframe transmitting terminal 810 and utilizes PDSCH or PDCCH to send the specific implementation process of dynamic scheduling information.

The dynamic scheduling information that subframe transmitting terminal 810 sends can be that subframe transmitting terminal 810 is according to data configuration to be sent.The content that the dynamic scheduling information that subframe transmitting terminal 810 sends specifically comprises can adopt multiple representation, and the description among concrete example such as the above-mentioned method embodiment is in this no longer repeat specification.

For avoiding the waste of interface-free resources, subframe transmitting terminal 810 can send non-MBMS data (as unicast service data etc.) in vacant subframe, after subscriber equipment then can be determined the position that has vacant subframe and vacant subframe according to dynamic scheduling information and MSAP information, use the non-MBMS data in the vacant subframe of pilot reception of normal CP and cell range.

The concrete structure of the control end 800 in the present embodiment such as the description of following embodiment 16, the description of the concrete structure of subframe transmitting terminal 810 such as following embodiment 17 is in this no longer repeat specification.

From the description of the foregoing description 15 as can be known, control end 800 is by selecting to meet the subframe that sends requirement for dynamic scheduling information, can guarantee that subscriber equipment can know the position of the MBSFN subframe that it needs timely, thereby subscriber equipment is only received at the MBSFN subframe that it needs, the phenomenon of having avoided subscriber equipment that unwanted MBSFN subframe is received, the power consumption of having saved UE.Subframe transmitting terminal 810 sends non-MBSFN subframe by utilizing vacant subframe, and, subscriber equipment judge have vacant subframe after, unicast service data in the CP that utilization is predetermined and the vacant subframe of pilot reception of cell range, make full use of vacant subframe, avoided the wasting phenomenon of valuable interface-free resources.
