Description
Technical field
The present invention relates to the technical field of message transmission in the mobile communication, relate in particular to the method and the device of feedback information in a kind of mbms service (MBMS).
Background technology
In Long Term Evolution (LTE, Long Term Evolvement) system, for improving the performance of system, system needs the user to the network side feedback-related information under specific circumstances, for example, in statistics (Counting) process of MBMS business, subscriber equipment (UE) needs feedback statistics response message; When transferring MBMS service data, UE need feed back (NACK) information unconfirmed and channel quality indication (CQI, Channel Quality Indicator) information etc.
At present, determine the application scenes of MBMS business in the LTE system, in some cases, the MBMS business is cancelled the transmission means of point-to-point (PTP), only adopts the transmission means of point-to-multipoint (PTM).Therefore, network side does not need to know the UE quantity of definite response statistics, as long as and know whether there is the UE that receives the MBMS business in the sub-district, this will simplify the statistics response process greatly.The present a kind of MBMS business statistics process that proposes, its flow process be as shown in Figure 1:
In step 101, network controller is gone up at MBMS control channel (MCCH, MBMS ControlChannel) and is sent statistics request (Counting Request) message.
In Counting Request message, comprise MBMS service identification and one " special-purpose access information ".According to special-purpose access information, UE can be known the employed access burst of its response statistics.
After receiving Counting Request message, in step 102, UE judges according to the MBMS service identification in the statistics request message whether this business is the business of its subscription, if then execution in step 104; Otherwise execution in step 103.
In step 103, UE does not respond statistics.
In step 104, UE goes up the described access burst of emission in Random Access Channel (RACH, Random Access Channel), and statistics is responded.
In step 105, after network side is received the statistics response, on MCCH, send the statistics end.At network side, base station (eNodeB) then can determine to have in the sub-district user to receive relevant MBMS business if receive described access burst.
Here it is pointed out that because all UE that receive described relevant MBMS business use identical access burst response statistics, so eNodeB can't be known the quantity of the UE of response statistics; But for the MBMS that only adopts the PTM mode to transmit was professional, eNodeB did not need to know the number of users of definite reception business, received professional user as long as know whether to exist.
For above-mentioned statistic processes, special-purpose access information is by MCCH channel notification UE.When UE does not subscribe to any MBMS when professional, this UE will can not intercept the MCCH channel, just not know to be exclusively used in the accidental access signal sequence of response statistics yet.When this UE uses this accidental access signal sequence as other purposes, erroneous judgement may appear in eNodeB.For example, actual in the sub-district do not have UE to receive the MBMS business, but in this measurement period, if a UE who does not intercept the MCCH channel utilizes this accidental access signal sequence to initiate a general service, to cause eNodeB to receive this accidental access signal sequence, and think the UE that has reception MBMS business by mistake.In case above-mentioned erroneous judgement takes place, not only will cause the professional transmission of unnecessary MBMS, but also can cause the access failure at random of this UE, this UE is inserted once more at random, prolonged the turn-on time of this UE.
In addition, the at present also content and the mechanism of the up feedback of UE in the professional transmission course of MBMS is discussed mainly comprise the content of this two aspect of NACK and CQI.Feedback mechanism for NACK and CQI, concrete implementation also is not discussed at present, if feed back alone and will bring very big up signaling traffic load according to the conventional method user, can have influence on the up process of domestic consumer, and the testing of eNodeB will increase greatly to system.

When network side was initiated statistic processes at professional MBMS1 or MBMS3, method was the same, here no longer repeat specification.
At network side,, then can determine to exist in the sub-district UE that wishes to receive corresponding MBMS business if eNodeB receives the special-purpose accidental access signal of statistics response.Because be hopeful to receive certain MBMS business UE all use identical accidental access signal response statistics, wish to receive described MBMS business so what UE eNodeB can not define.Owing to adopt the PTM mode to transmit described MBMS business, so eNodeB do not need to know the definite UE number of wishing to receive described MBMS business yet, as long as and know have UE to wish to receive just passable.
Here also it is to be noted, in actual applications, can distribute fixing special-purpose accidental access signal for the statistics corresponding information of each MBMS business, and, be the shared special-purpose accidental access signal of statistics corresponding information distribution of each MBMS business according to actual conditions.
In embodiment 1, though network side can provide 3 MBMS business, correspondingly, 3 statistics response messages are arranged, network side can only be that 3 statistics response messages are distributed 2 special-purpose accidental access signals.
When the network side decision is initiated statistic processes at professional MBMS2, can indicate the special-purpose accidental access signal of accidental access signal T1 for the statistics response.When the network side decision is initiated statistic processes at professional MBMS1, can indicate the special-purpose accidental access signal of accidental access signal T2 for the statistics response.After the statistic processes end at professional MBMS2, when the network side decision is initiated statistic processes at professional MBMS3, the special-purpose accidental access signal that can indicate accidental access signal T1 to respond once more for statistics, thus realized sharing of special-purpose accidental access signal.
As can be seen, in embodiment 1, behind the accidental access signal of network side for statistics response message distribution special use, notify all UE by system message with the described relations of distribution, make all UE described special-purpose accidental access signal can be used for his way, thereby avoid the special-purpose accidental access signal of MBMS business to be misapplied, also correspondingly eliminated the possibility of eNodeB erroneous judgement, shortened the time that UE inserts at random by UE.
The at present content and the mechanism of the up feedback of UE in the professional transmission course of the MBMS that discusses mainly comprise the content of this two aspect of NACK and CQI.For the feedback mechanism of NACK and CQI, concrete implementation also is not discussed at present, the present invention proposes the method for UE feedback NACK in the professional transmission course of a kind of MBMS.
Below,, 2 pairs of methods provided by the invention are done further and are specified in conjunction with the embodiments, and Fig. 3 is the flow chart of embodiment 2.
In step 301, distribute special-purpose accidental access signal at network side.
In step 302, network side is by the information notice UE of the system information on the BCCH with special-purpose accidental access signal.
UE is by the system information on the BCCH, can know which accidental access signal is the accidental access signal of the special use of network side distribution, like this, even UE does not intercept the MCCH channel, can know special-purpose accidental access signal, any UE can not be used for the accidental access signal of special use his way yet.
In step 303, when certain MBMS of network side decision transmission is professional, will notifies UE by MCCH, and on MCCH, carry the indication information of the special-purpose accidental access signal of NACK in this MBMS business.
In step 304, UE according to described indication information, sends corresponding special-purpose accidental access signal on RACH when receiving described MBMS business and needing feedback NACK.
In step 305, network side detects described special-purpose accidental access signal on RACH, can know UE feedback NACK, and then whether decision retransmits.
More particularly, suppose that network side can provide 3 MBMS business, service identification is respectively MBMS1, MBMS2 and MBMS3.The special-purpose accidental access signal that distributes is N1, N2.
Network side is notified UE by the system information on the BCCH with assignment information, and UE will know that N1, N2 are special-purpose accidental access signal, and any UE can be with accidental access signal N1, N2 as his way.
During network side decision transport service MBMS2, will notify UE on MCCH, and carry indication information on MCCH, indication accidental access signal N1 is the special-purpose accidental access signal of NACK.UE when feedback information NACK, will send accidental access signal N1 according to described indication information on RACH in the process that receives professional MBMS2.
When network side transport service MBMS1 or MBMS3, method is the same, here no longer repeat specification.
Here it is pointed out that equally in actual applications, can distribute fixing special-purpose accidental access signal for the NACK of each MBMS business, and, be the shared special-purpose accidental access signal of NACK distribution of each MBMS industry according to actual conditions.
The present invention also proposes the method for UE feedback CQI in the professional transmission course of a kind of MBMS.
Below,, 3 pairs of methods provided by the invention are done further and are specified in conjunction with the embodiments, and Fig. 4 is the flow chart of embodiment 3.
In step 401, distribute special-purpose accidental access signal at network side.
Wherein, the indication of CQI comprises the increase indication information and reduces indication information that correspondingly, special-purpose accidental access signal also is divided into special-purpose accidental access signal that increases indication information and the special-purpose accidental access signal that reduces indication information.
In step 402, network side by the system information on the BCCH with all UE in the information notifying cell of special-purpose accidental access signal.
UE is by the system information on the BCCH, can know which accidental access signal is the accidental access signal of the special use of network side distribution, like this, even UE does not intercept the MCCH channel, can know special-purpose accidental access signal, any UE can not be used for the accidental access signal of special use his way yet.
In step 403, when certain MBMS of network side decision transmission is professional, will notifies UE by MCCH, and on MCCH, carry the indication information of the special-purpose accidental access signal of CQI in this MBMS business.
In step 404, UE according to described indication information, sends corresponding special-purpose accidental access signal on RACH when receiving described MBMS business and needing feedback corresponding C QI.
In step 405, network side detects described special-purpose accidental access signal on RACH, can know that the CQI of UE feedback still increases indication information for reducing indication information, and according to the grade of transmission of this signal deciding reduction or rising MBMS business.
Here it is pointed out that equally in actual applications, can distribute fixing special-purpose accidental access signal for the CQI of each MBMS business, and, be the shared special-purpose accidental access signal of CQI distribution of each MBMS industry according to actual conditions.
Those skilled in the art as can be seen, when network side supports that a plurality of MBMS are professional, embodiment 1, embodiment 2 and embodiment 3 described methods are carried out combination, the statistics response message, NACK and the CQI that promptly can be in each MBMS business distribute special-purpose accidental access signal, and can reach purpose of the present invention.
For example: suppose that network side can provide 2 MBMS business, service identification is respectively MBMS1, MBMS2, and the special-purpose accidental access signal of distribution is M1, M2, M3, M4, M5, M6, M7 and M8.Network side is notified UE by the system information on the BCCH with assignment information, UE will know that M1, M2, M3, M4, M5, M6, M7 and M8 are special-purpose accidental access signal, and any UE can not be used for accidental access signal M1, M2, M3, M4, M5, M6, M7 and M8 his way.
When the network side decision is initiated statistic processes at professional MBMS2, will send the statistics request message on MCCH, and carry the indication information of accidental access signal M1 on MCCH, indication accidental access signal M1 is the special-purpose accidental access signal of statistics response.Subscribed to the UE of professional MBMS2, will on RACH, send accidental access signal M1 according to described indication information, with the response statistics.Network side judges whether it receives accidental access signal M1, to determine whether to exist the UE that wishes to receive professional MBMS2.
During network side transport service MBMS2, to on MCCH, send indication information, indication accidental access signal M2 is the special-purpose accidental access signal of NACK, accidental access signal M3 is the special-purpose accidental access signal that CQI increases indication information, and accidental access signal M4 is the special-purpose accidental access signal that CQI reduces indication information.UE when feedback NACK, will send accidental access signal M2 according to indication information on RACH in the process that receives professional MBMS2; When feeding back the increase indication information of CQI, will on RACH, send accidental access signal M3; When the feedback CQI reduce indication information the time, will on RACH, send accidental access signal M4.
When network side transport service MBMS1, method is the same, here no longer repeat specification.
In above-mentioned all embodiment, network side all is to select the special-purpose random access code of a part of public random access code as the professional related feedback information of MBMS in the public random access code of sub-district.Since a part of public random access code as special-purpose random access code after, these public random access codes will can not be used as other purposes, the public random access code that causes that UE can use in the sub-district reduces, and increased the collision probability that UE uses public random access code.
The present invention also provides the method for feedback information in a kind of MBMS business, and this method is not to adopt the public random access code of sub-district as special-purpose random access code, but with the specific code that is different from the public random access code in sub-district as special-purpose random access code.Below, 4 pairs of these methods are done and are specified in conjunction with the embodiments, and Fig. 5 is the flow chart of embodiment 4.
In step 501, at network side, the signal that is different from the public random access code in sub-district is set to special-purpose accidental access signal.
In step 502, network side is by MCCH, and the indication information of the special-purpose accidental access signal of the professional related feedback information of MBMS is sent to UE.
In step 503, network side receives the special-purpose accidental access signal that UE sends, and definite UE feedack.
More particularly, the public random access code in existing sub-district is a cyclic shift Zadoff-Chu sequence, can pseudo random sequence as special-purpose accidental access signal, with respect to cyclic shift Zadoff-Chu sequence, pseudo random sequence can be considered to white noise.Add pseudo random sequence in the sub-district, the influence that network side is detected cyclic shift Zadoff-Chu sequence is very little.
Suppose that network side can provide 2 MBMS business, service identification is respectively MBMS1, MBMS2, with pseudo random sequence m1, m2, m3, m4, m5, m6, m7 and m8 as special-purpose accidental access signal.When the network side decision is initiated statistic processes at professional MBMS2, will send the statistics request message on MCCH, and carry the indication information of accidental access signal m1 on MCCH, indication accidental access signal m1 is the special-purpose accidental access signal of statistics response.Subscribed to the UE of professional MBMS2, will on RACH, send accidental access signal m1 according to described indication information, with the response statistics.Network side judges whether it receives accidental access signal m1, to determine whether to exist the UE that wishes to receive professional MBMS2.
During network side transport service MBMS2, to on MCCH, send indication information, indication accidental access signal m2 is the special-purpose accidental access signal of NACK, accidental access signal m3 is the special-purpose accidental access signal that CQI increases indication information, and accidental access signal m4 is the special-purpose accidental access signal that CQI reduces indication information.UE when feedback NACK, will send accidental access signal m2 according to indication information on RACH in the process that receives professional MBMS2; When feeding back the increase indication information of CQI, will on RACH, send accidental access signal m3; When the feedback CQI reduce indication information the time, will on RACH, send accidental access signal m4.
As can be seen, because pseudo random sequence is not the public random access code in sub-district, so each UE can not adopt pseudo random sequence when the information of transmission, just solved the problem that special-purpose accidental access signal is misapplied by UE yet.Only when network side was initiated certain MBMS business, UE could know which pseudo random sequence is the special-purpose accidental access signal of feedback information according to the indication of network side.And this method does not take the resource of the public random access code in sub-district, has reduced the collision probability that UE uses public random access code.
Based on said method, the present invention also proposes the device of feedback information in the corresponding M BMS business.Fig. 6 is a kind of schematic diagram of this device, and this device comprises: first information unit 61, second information unit 62 and feedback transmitting element 63.
After network side distributes special-purpose accidental access signal, network side will be notified UE by the special-purpose accidental access signal that the system information on the BCCH will be distributed.
At UE, can utilize first information unit 61, know that by the system information on the BCCH which accidental access signal is the accidental access signal of the special use of network side distribution, like this, even UE does not intercept the MCCH channel, can know special-purpose accidental access signal, any UE can not be used for the accidental access signal of special use his way yet.
When network side determines initiation or transmits certain MBMS business, will on MCCH, send the indication information of the special-purpose accidental access signal of the professional related feedback information of this MBMS.Wherein, the related feedback information of described MBMS business comprises the increase indication information of adding up response message, NACK and CQI, reduces indication information.
Subscribe to the UE of described MBMS business, can utilize second information unit 62 to intercept MCCH, obtain the indication information of the special-purpose accidental access signal of the professional related feedback information of MBMS, thereby make UE know the special-purpose accidental access signal of the professional related feedback information of MBMS.
When described UE carries out the relevant feedback of MBMS business, can utilize feedback transmitting element 63,, on RACH, send corresponding special-purpose accidental access signal, to feed back accordingly according to the indication information of special-purpose accidental access signal.
Network side is received the accidental access signal of described special use, knows the UE that has the response statistics.
This device can also comprise forbids the unit, after UE utilizes first information unit 61 to know which accidental access signal is the accidental access signal of the special use that distributes of network side, forbid that the unit forbids adopting described special-purpose accidental access signal when network side sends out of Memory, can utilizing.
Fig. 7 is the device of feedback information among the another kind of MBMS that proposes of the present invention, and this device comprises first notification unit 71, second notification unit 72 and feedback acknowledgment unit 73.
At network side, utilize first notification unit 71, can notify UE with the special-purpose accidental access signal that network side distributes by system information.
UE is by the system information on the BCCH, can know which accidental access signal is the accidental access signal of the special use of network side distribution, like this, even UE does not intercept the MCCH channel, can know special-purpose accidental access signal, any UE can not be used for the accidental access signal of special use his way yet.
Network side decision is initiated or is transmitted certain MBMS when professional, will utilize second notification unit 72 at MCCH the indication information of the special-purpose accidental access signal of the professional related feedback information of MBMS to be sent to UE.Wherein, the related feedback information of described MBMS business comprises the increase indication information of adding up response message, NACK and CQI, reduces indication information.
When the UE that subscribes to described MBMS business carries out the relevant feedback of MBMS business, will on RACH, send corresponding special-purpose accidental access signal, to feed back accordingly according to the indication information of special-purpose accidental access signal.
At network side, can utilize feedback acknowledgment unit 73 to receive special-purpose accidental access signal and definite UE feedack that UE sends.
Adopt device shown in Figure 7, behind the accidental access signal of network side for statistics response message distribution special use, notify all UE by system message with the described relations of distribution, make all UE described special-purpose accidental access signal can be used for his way, thereby avoid the special-purpose accidental access signal of MBMS business to be misapplied by UE, also correspondingly eliminate the possibility of eNodeB erroneous judgement, shortened the time that UE inserts at random.
In Fig. 6 and device shown in Figure 7, network side all is to select the special-purpose random access code of a part of public random access code as the professional related feedback information of MBMS in the public random access code of sub-district.Since a part of public random access code as special-purpose random access code after, these public random access codes will can not be used as other purposes, the public random access code that causes that UE can use in the sub-district reduces, and increased the collision probability that UE uses public random access code.
The present invention also provides the device of feedback information in a kind of MBMS business, and this device is not to adopt the public random access code of sub-district as special-purpose random access code, but with the specific code that is different from the public random access code in sub-district as special-purpose random access code.
Fig. 8 is this schematic representation of apparatus, and this device comprises unit 81, notification unit 82 and feedback acknowledgment unit 83 are set.
At network side, utilize the signal that unit 81 is different from the public random access code in sub-district to be set to be set to special-purpose accidental access signal.Wherein, the described signal that is different from the public random access code in sub-district can m sequence, i.e. pseudo random sequence.
When network side determines initiation or transmits certain MBMS business, will utilize notification unit 82 on MCCH, to send the indication information of the special-purpose accidental access signal of the professional related feedback information of this MBMS.Wherein, the related feedback information of described MBMS business comprises the increase indication information of adding up response message, NACK and CQI, reduces indication information.
When the UE that subscribes to described MBMS business carries out the relevant feedback of MBMS business, will on RACH, send corresponding special-purpose accidental access signal, to feed back accordingly according to the indication information of special-purpose accidental access signal.
At network side, can utilize feedback acknowledgment unit 83 to receive special-purpose accidental access signal and definite UE feedack that UE sends.
As can be seen, because pseudo random sequence is not the public random access code in sub-district, so each UE can not adopt pseudo random sequence when the information of transmission, just solved the problem that special-purpose accidental access signal is misapplied by UE yet.Only when network side was initiated certain MBMS business, UE could know which pseudo random sequence is the special-purpose accidental access signal of feedback information according to the indication of network side.And this method does not take the resource of the public random access code in sub-district, has reduced the collision probability that UE uses public random access code.
Above-described embodiment only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
