The user is by the signaling of base station 10, and subscriber equipment 20 is determined the professional physical resource that compensates the place of the MBMS that loses, and receives the professional compensation of the described MBMS that loses from described physical resource.A compensation RNTI who is provided with for Fig. 2 a identifies, the compensating unit 24 of subscriber equipment 20 can obtain one or more MBMS business that correspondence is lost from the passage of this sign indication, perhaps from a plurality of compensation RNTI signs that Fig. 2 b is provided with, thereby select suitable R NTI to identify the channel of indication by understanding the corresponding MBMS class of business of losing of each RNTI sign, and therefrom obtain the MBMS business that it need compensate.
Except compensating by the mode that special RNTI is set, bucking-out system of the present invention can also be by the high-level signaling of base station 10 transmissions, and for example multicast control channel (MCCH) signaling compensates.Base station 10 needs the MBMS business of compensation by the direct notifying user equipment 20 of MCCH.For example the professional present physical resource of MBMS of compensation is notified in base station 10 in MCCH, and subscriber equipment 20 removes to receive corresponding M BMS to the residing physical resource and loses business then.
In an embodiment, base station 10 can be on the different resource of the professional mapping of different MBMS compensation, equally also can be mapped to then on the identical resource in that high level is multiplexing different MBMS compensation is professional.
It is to be noted, only shown a subscriber equipment 20 for convenience of description among Fig. 1, but in actual applications, bucking-out system of the present invention can comprise a plurality of subscriber equipmenies, and base station 10 can compensate setting for the MBMS loss of traffic of the subscriber equipment of a plurality of connection status.As shown in Figure 3, this figure embodiment has shown the bucking-out system of the MBMS reception with a plurality of subscriber equipmenies 20,30.Here, the structure of each subscriber equipment is identical with the subscriber equipment 20 of Fig. 1 embodiment.What therefore the MBMS business that exists in measurement clearance for a plurality of subscriber equipmenies 20,30 received loses, each subscriber equipment 20,30 reports base station 10 with the MBMS business that receives, and the compensation RNTI sign that unit 16 is provided with is set according to the compensation sign, perhaps according to the high-level signaling of base station 10, thereby to corresponding channel, receive corresponding MBMS business realizing compensation of losing.
Here, a plurality of MBMS business that a plurality of subscriber equipmenies are lost can also can be placed in a plurality of compensation RNTI signs by the indication of single compensation RNTI sign, and each compensation RNTI identifies corresponding a kind of MBMS business.
In one embodiment, the measurement clearance dispensing unit 14 of base station 10 can be to receiving the identical measurement clearance of a plurality of subscriber equipmenies (for example subscriber equipment 20 and 30 of Fig. 3 embodiment) configuration of same MBMS business.Like this, if there is the MBMS loss of traffic in these subscriber equipmenies, the data of then losing also are identical.Thereby, thereby can unify compensation by a plurality of subscriber equipmenies according to the same MBMS business that identical measurement clearance correspondence is lost.
Measurement clearance dispensing unit 14 can determine identical measurement clearance according to following formula:
SFN mod T＝FLOOR(gapOffset/10) (1)
subframe＝gapOffset mod 10 (2)
Wherein, SFN represents System Frame Number (system frame number), and T represents it is residing measuring period of measurement clearance, for example is 40ms or 80ms, and gapOffset represents the gap skew.Formula 1 is used for determining the measurement clearance place starting point of measuring period, and 2 of formula are used for the starting point subframe of allocating and measuring gap.Wherein T is 4 when cycle of 40ms, and the gapoffset span is 0 to 39, and T is 8 when cycle of 80ms, and the gapoffset span is 0 to 79.
From above-mentioned formula as can be seen, as long as just can guarantee that with gapoffset subscriber equipment has identical measurement clearance to the identical T of user device configuration.
For example, base station 10 is understood subscriber equipmenies 20 and is being received identical MBMS business with subscriber equipment 30, here identical can be identical also can be that part is identical.For example, subscriber equipment 20 receives 1,3 business, and subscriber equipment 30 also receives 1,3 business; Perhaps subscriber equipment 20 receives 1,3 business, and subscriber equipment 30 receives 3,5 business.Like this, there is the identical MBMS business of small part that receives in two subscriber equipmenies.Therefore, base station 10 can be to these two subscriber equipmenies 20 and the identical measurement clearance of 30 configurations.
If subscriber equipment 20 and 30 has all been lost 1,3 business, then identify the channel of indication or high-level signaling notice by compensation RNTI, can carry out unified compensation to subscriber equipment 20 and 30 these business of losing, thereby further simplify the loss compensation operation that a plurality of subscriber equipmenies receive the same MBMS business.
With reference now to Fig. 4,, Fig. 4 is the compensation method flow chart of steps that the MBMS MBMS of the embodiment of the invention receives.
As shown in the figure, subscriber equipment reports (step 102) with the MBMS business that receives to the base station, subscriber equipment corresponding MBMS business (step 104) of losing in measurement clearance is determined according to the measurement clearance that described reception MBMS is professional and subscriber equipment is given in configuration that reports in the base station.Then, the base station is according to the MBMS business setting MBMS that loses professional compensation Radio Network Temporary Identifier RNTI or send high-level signaling, with the described MBMS business (step 106) of losing of indication subscriber equipment compensation.
The subscriber equipment of connection status just needs allocating and measuring gap (GAP), and therefore at this moment the base station of network side can be the user device configuration measurement clearance of connection status.Except measurement clearance was set, the base station also was provided for the Radio Network Temporary Identifier (RNTI) of MBMS compensation for subscriber equipment, with the channel at the professional place of indication subscriber equipment compensation MBMS.Perhaps, the base station by the MBMS compensation that RNTI is used for subscriber equipment is set, is not used for the high-level signaling that MBMS compensates but send.RNTI sign that the base station is provided with or the high-level signaling that sends, be to determine that according to the MBMS of user equipment to report is professional corresponding MBMS business of losing is implemented in the measurement clearance, thereby how notifying user equipment is obtained on the respective channels of indication or the physical resource and is lost professional compensated information.Wherein, the base station can and dispose the measurement clearance of giving subscriber equipment according to MBMSFN subframe in the reception MBMS business of user equipment to report, judge whether subscriber equipment exists the MBMS loss of traffic in this measurement clearance, and what the MBMS business of losing is.
The MBMS business of subscriber equipment reports, and for example can control (RRC) signaling or medium access control (MAC) control element (CE) by Radio Resource and carry out.According to the indication of compensation RNTI sign or the notice of high-level signaling, subscriber equipment compensates the MBMS business of losing at the subscriber equipment end.
Can in RNTI form (shown in Fig. 2 a), a special RNTI be set about being provided with of the professional compensation of MBMS of the present invention Radio Network Temporary Identifier RNTI and compensate, for example hexadecimal numerical value FFF3 is defined as the professional compensation of MBMS RNTI sign.If subscriber equipment is found to cause loss of traffic owing to measuring GAP like this, then can after measuring GAP, monitor the professional compensation of MBMS RNTI sign in a period of time, and then the business of compensating missing.A plurality of MBMS business of losing of subscriber equipment correspondence can all be placed in the channel of this RNTI indication and compensate.
Perhaps, the base station can keep in RNTI form (shown in Fig. 2 b) and a plurality ofly compensates for the professional compensation of MBMS RNTI identify, and for example hexadecimal numerical value FFF3-FFF8 is defined as the professional compensation of MBMS RNTI sign.Wherein each RNTI identifies corresponding a kind of MBMS business of losing.
Monitor the compensation RNTI sign of base station configuration by subscriber equipment, thereby on the channel of compensation RNTI sign indication, receive the professional compensation of the corresponding MBMS that loses.Subscriber equipment can keep continuing to monitor.Certainly, subscriber equipment can also be according to the measurement clearance of base station configuration, at first determine the MBMS business that correspondence is lost in the measurement clearance in the professional reception of MBMS, thereby when determining to have the MBMS loss of traffic, after corresponding measurement clearance, compensate the monitoring of RNTI sign again in the scheduled time, to reduce the resource loss of system.
A compensation RNTI who is provided with for Fig. 2 a identifies, subscriber equipment can obtain one or more MBMS business that correspondence is lost from the passage of this sign indication, perhaps from a plurality of compensation RNTI signs that Fig. 2 b is provided with, by understand each RNTI sign corresponding lose the MBMS class of business, and determine lose class of business, thereby select the channel of suitable R NTI sign indication, and therefrom obtain the MBMS business that it need compensate.
As indicated above, except compensating by the mode that special RNTI is set, compensation method of the present invention can also be by the high-level signaling of base station transmission, and for example multicast control channel (MCCH) signaling compensates.The MBMS business that the base station need compensate by the direct notifying user equipment of MCCH.For example the professional present physical resource of MBMS of compensation is notified in the base station in MCCH, and subscriber equipment removes to receive corresponding M BMS to the residing physical resource and loses business then.
In an embodiment, the base station can be on the different resource of the professional mapping of different MBMS compensation, equally also can be mapped to then on the identical resource in that high level is multiplexing different MBMS compensation is professional.
In actual applications, may there be the compensation of a plurality of subscriber equipmenies being lost the MBMS business.In this case, above-mentioned compensation setting can be carried out for the MBMS loss of traffic of the subscriber equipment of a plurality of connection status in the base station.What therefore the MBMS business that exists in measurement clearance for a plurality of subscriber equipmenies received loses, and each subscriber equipment is by the measurement clearance of base station configuration, and each subscriber equipment is determined corresponding separately MBMS business of losing.And the compensation RNTI sign that is provided with according to the base station perhaps according to the high-level signaling of base station, thereby receives corresponding MBMS business realizing compensation of losing to corresponding channel.
Here, a plurality of MBMS business that a plurality of subscriber equipmenies are lost can also can be placed in a plurality of compensation RNTI signs by the indication of single compensation RNTI sign, and each compensation RNTI identifies corresponding a kind of MBMS business.
In addition, also exist the subscriber equipment of a plurality of reception same MBMS business to lose professional situation in the practical application.At this moment, the base station can receive the identical measurement clearance of a plurality of user device configuration of same MBMS business to these.For the UE of connection status, know the corresponding informance of UE to comprise what MBMS business this UE is receiving fully by the reporting base station of UE, which UE receives identical MBMS business or the like.Therefore, a plurality of subscriber equipmenies of receiving the same MBMS business that can achieve a butt joint are provided with identical measurement clearance.Like this, if there is the MBMS loss of traffic in these subscriber equipmenies, the data of then losing also are identical.Thereby, thereby can unify compensation by a plurality of subscriber equipmenies according to the same MBMS business that identical measurement clearance correspondence is lost.
The base station can dispose identical measurement clearance according to following formula:
SFN mod T＝FLOOR(gapOffset/10) (3)
subframe＝gapOffset mod 10 (4)
Wherein, SFN represents System Frame Number (system frame number), and T represents it is residing measuring period of measurement clearance, for example is 40ms or 80ms, and gapOffset represents the gap skew.Formula 3 is used for determining the measurement clearance place starting point of measuring period, and formula 4 is used for the starting point subframe of allocating and measuring gap.Wherein T is 4 when cycle of 40ms, and the gapoffset span is 0 to 39, and T is 8 when cycle of 80ms, and the gapoffset span is 0 to 79.
From above-mentioned formula as can be seen, as long as just can guarantee that with gapoffset subscriber equipment has identical measurement clearance to the identical T of user device configuration.
If a plurality of subscriber equipmenies have all been lost identical MBMS business, then identify the channel of indication or high-level signaling notice by compensation RNTI, can carry out unified compensation to this business of losing of these subscriber equipmenies, thereby further simplify the loss compensation operation that a plurality of subscriber equipmenies receive the same MBMS business.
