Embodiment

For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.

The means of communication of the embodiment of the present invention are the scenes of the carrier aggregation technology be applied to across base station.Such as, when the transmission of user data service is born at least two base stations simultaneously time, subscriber equipment needs to carry out transfer of data with these at least two base stations respectively, and this data transfer mode is called across station multi-stream mode.Across station multi-stream mode under, subscriber equipment can carry out communication with multiple communities of multiple base station.Such as, coordinate multipoint (coordinated multi-point, CoMP) transmission technology can be supported across station multi-stream mode, in order to reduce cell edge interference, to improve cell edge throughput; Or support carrier aggregation (carrier aggregation, CA) technology, in order to improve peak data rate, community average throughput etc.Wherein, a community in above-mentioned multiple community can be main plot (primarycell, PCell), and other community can Shi Fu community (secondary cell, SCell).For main plot provides the base station of service to be called main serving BS (primary base station), for auxiliary community provides the base station of service to be called auxiliary serving BS (secondary base station).

Fig. 1 is the application system Organization Chart of means of communication embodiment of the present invention, as shown in Figure 1, participate in being polymerized to example with three of two base stations communities, one of them is main serving BS, another is auxiliary serving BS, participate in three communities of polymerization, under main plot and a Ge Fu community belong to main serving BS, under another auxiliary community belongs to auxiliary serving BS.Subscriber equipment sends the prior scheduling that upstream data needs base station equally to multiple base station.The BSR needing to obtain subscriber equipment for the scheduling of upstream data is carried out in each base station, and this BSR comprises the upstream data amount to be sent of subscriber equipment.After the upstream data amount to be sent of the subscriber equipment that this base station receives, then according to the wireless channel condition of this subscriber equipment, ascending resource is distributed to subscriber equipment, subscriber equipment uses the ascending resource transmit ascending data distributed.

In the present embodiment, there is multiple base station, main serving BS or auxiliary serving BS can be comprised.In each embodiment below, be also mainly describe subscriber equipment how to send upstream data across base station, realize the process of data distribution.

The techniques described herein may be used in various communication system, such as current 2G, 3G communication system and next generation communication system, such as global system for mobile communications (GSM, Global System forMobile communications), code division multiple access (CDMA, Code Division MultipleAccess) system, time division multiple access (TDMA, Time Division Multiple Access) system, Wideband Code Division Multiple Access (WCDMA) (WCDMA, Wideband Code Division Multiple AccessWireless), frequency division multiple access (FDMA, Frequency Division Multiple Addressing) system, OFDM (OFDMA, Orthogonal Frequency-Division MultipleAccess) system, Single Carrier Frequency Division Multiple Access (SC-FDMA) system, GPRS (GPRS, General Packet Radio Service) system, Long Term Evolution (LTE, Long Term Evolution) system, and other these type of communication systems.

The subscriber equipment related in the application, can be wireless terminal also can be catv terminal, wireless terminal can be point to the equipment that user provides voice and/or data connectivity, has the portable equipment of wireless connecting function or is connected to other treatment facilities of radio modem.Wireless terminal can through wireless access network (such as, RAN, Radio Access Network) communicate with one or more core net, wireless terminal can be mobile terminal, as mobile phone (or being called " honeycomb " phone) and the computer with mobile terminal, such as, can be portable, pocket, hand-hold type, built-in computer or vehicle-mounted mobile device, they and wireless access network exchange language and/or data.Such as, Personal Communications Services (PCS, Personal Communication Service) phone, cordless telephone, Session Initiation Protocol phone, wireless local loop (WLL, Wireless Local Loop) stand, the equipment such as personal digital assistant (PDA, Personal Digital Assistant).Wireless terminal also can be called system, subscri er unit (Subscriber Unit), subscriber station (Subscriber Station), mobile radio station (Mobile Station), travelling carriage (Mobile), distant station (Remote Station), access point (Access Point), remote terminal (Remote Terminal), access terminal (AccessTerminal), user terminal (User Terminal), user agent (User Agent), subscriber equipment (User Device) or subscriber's installation (User Equipment).

The base station (such as, access point) related in the application, can to refer in Access Network the equipment by one or more sector and wireless terminal communications on aloft interface.Base station can be used for the air frame received and IP to divide into groups mutually to change, and as the router between wireless terminal and the remainder of Access Network, wherein the remainder of Access Network can comprise Internet protocol (IP) network.Base station also tunable to the attribute management of air interface.Such as, base station can be the base station (BTS, Base Transceiver Station) in GSM or CDMA, also can be the base station (NodeB) in WCDMA, can also be the evolved base station (NodeB or eNB or e-NodeB, evolutional NodeB) in LTE, the application limit.

In order to below making to send BSR method description clearly and be easier to understand, first the related notion related in the method is described as follows:

Mainly comprise across the shunting mode under station multithread scene:

Every Resource Block (per resource block, be called for short Per RB) shunting: adopt this shunting mode, each business of subscriber equipment is immediately newly-built, need the logic channel at this business place and a base station association, after business is set up, all data all send via this association base station.Association base station information, once configure, can not dynamically change, and generally only has the signal weaker when association base station, or during lower than a certain thresholding, the logic channel that just can be carried is associated with another base station.

Every packet (per packet) is shunted: adopt this shunting mode, each business of subscriber equipment is immediately newly-built, not by the logic channel at this business place and any base station association.When needing transmission data, transmit according to the base station that the instant situation of channel is as suitable in the selection such as load, decay one.So the data of same business may pass through multiple base-station transmission.

Logic channel group (logic channel group, be called for short LCG): can by base station by wireless heterogeneous networks (radio resource control, RRC) signaling is user device configuration, and such as, the data of close priority or signaling can be placed in a logic channel group.Subscriber equipment reports BSR to base station time, report granularity can be report in units of logic channel group.

Multiple logic channels of a subscriber equipment are included into different logic channel groups, and during base station scheduling, the priority of each logic channel group is different.During user equipment to report BSR, add up the upstream data amount pending of each logic channel group, separately report, do accurate scheduling decision for base station.If subscriber equipment does not trigger BSR, but after discharging upstream data, also have some vacant Radio Resources, cannot put upstream data again, now subscriber equipment can send the BSR of brachymemma or the BSR(Padding BSR of filling).If now subscriber equipment has multiple logic channel group to have upstream data pending, then subscriber equipment sends the BSR of brachymemma to base station, wherein comprises priority the highest and have the upstream data amount pending of that logic channel group of upstream data pending; If now subscriber equipment only has a logic channel group to have upstream data pending, then UE sends padding BSR to base station, only can comprise the upstream data amount pending that this has the logic channel group of data.

In above-mentioned flow process, subscriber equipment sends BSR itself to base station also need ascending resource, ascending resource is distributed to subscriber equipment in the moment needed in order to allow base station, it is made to report BSR smoothly, LTE system introduces dispatch request (scheduling request, SR) mechanism, SR mechanism refers to that base station is some SR resources of user device configuration, these SR resources periodically occur, itself is very little, subscriber equipment can use SR resource tell base station have data need send, as specifically there being how many data to send, also need BSR to indicate in detail.

Leaky bucket mechanism: until trigger BSR from configuration shunt ratio, subscriber equipment statistics is via the data volume summation of the upstream data of two base-station transmissions, and select a ratio lower than the base station of default shunt ratio, be used for this base station sending the BSR that this subscriber equipment triggers.Such as, the first pre-configured base station and the shunt ratio of second are respectively 30% and 70%.During to triggering BSR, the data volume of the upstream data that subscriber equipment sends via the first base station is 295Bytes, and the data volume of the upstream data sent via the second base station is 705Bytes, and data total amount is 1000Bytes.The actual shunt ratio of this subscriber devices compute, and compare with default shunt ratio, comparative result is as follows:

To the first base station: 295/1000<0.3(30%); To the second base station: 705/1000>0.7(70%).

So when subscriber equipment triggers next BSR, selected first base station is as the base station sending BSR.

The schematic flow sheet of a kind of means of communication that Fig. 2 provides for the embodiment of the present invention, comprising:

21: subscriber equipment obtains the default shunt ratio sending upstream data at least two base stations.

Optionally, subscriber equipment can obtain this default shunt ratio in the following way:

The default shunt ratio of self and the default shunt ratio of other arbitrary base station are sent to subscriber equipment by signaling by a base station at least two base stations; Or,

The default shunt ratio of self correspondence is sent to subscriber equipment by signaling by each base station.

Above-mentioned signaling can be specially wireless heterogeneous networks (radio resource control, RRC) signaling.

Such as, for two base stations, these two base stations are called the first base station and the second base station, can be so the first base station sends RRC signaling to subscriber equipment, the default shunt ratio that can comprise the first base station in this RRC signaling be 30% and the default shunt ratio that also comprises the second base station be 70%; Or, also can be that the first base station sends a RRC signaling to subscriber equipment, the default shunt ratio comprising the first base station in one RRC signaling is 30%, and second base station to subscriber equipment send the 2nd RRC signaling, the default shunt ratio comprising the second base station in the 2nd RRC signaling is 70%.

22: described subscriber equipment obtains actual shunt ratio according to the upstream data amount sent to described at least two base stations in preset time period.

Optionally, this preset time period can be obtain the time period of this default shunt ratio to this subscriber equipment triggering BSR from subscriber equipment.

Optionally, this upstream data amount can comprise the upstream data amount that this subscriber equipment sends to arbitrary base station in this preset time period, such as, for two base stations, this upstream data amount comprises subscriber equipment in this preset time period to the first upstream data amount that the first base station sends, and, subscriber equipment in this preset time period to second base station send the second upstream data amount.

Subscriber equipment, after obtaining upstream data amount corresponding to each base station, just can obtain actual shunt ratio according to upstream data amount corresponding to this base station and total upstream data amount.Such as, under the scene of above-mentioned two base stations, the actual shunt ratio of the first base station is: the first upstream data amount/(the first upstream data amount+the second upstream data amount), and the actual shunt ratio of the second base station is: the second upstream data amount/(the first upstream data amount+the second upstream data amount).

Due to the shunt ratio that will reach that default shunt ratio is setting, belong to the attribute of long-term macroscopic view, but on concrete short-term microcosmic, actual shunt ratio may be different from default shunt ratio, and the factor affecting actual shunt ratio may be load of base station, signal quality, at least one item of eating dishes without rice or wine in the factors such as quality.

23: described subscriber equipment, according to described default shunt ratio and described actual shunt ratio, sends BSR to a base station in described at least two base stations.

Optionally, described subscriber equipment, according to described default shunt ratio and described actual shunt ratio, sends described BSR to the base station of in described base station, specifically comprises:

The base station that described subscriber equipment is less than or equal to described default shunt ratio to described actual shunt ratio sends described BSR.

Such as, the default shunt ratio of the first base station is 30%, the default shunt ratio of the second base station is 70%, and the actual shunt ratio of the first base station obtained during actual count is less than 30% and the actual shunt ratio of the second base station is greater than 70%, so selects the first base station to send BSR.

Default shunt ratio due to each base station is the target that will reach, and therefore, the base station actual shunt ratio being less than or equal to default shunt ratio sends BSR, the actual shunt ratio of each base station can being made near presetting shunt ratio, reaching the target of setting.

Optionally, at least two above-mentioned base stations can comprise two base stations, or comprise more than two base stations.

When above-mentioned at least two base stations comprise two base stations, these at least two base stations comprise the first base station and the second base station, and the base station that described actual shunt ratio is less than or equal to described default shunt ratio is described first base station;

Now, the method specifically comprises:

When described subscriber equipment receives the first ascending resource of described first base station transmission, and described first ascending resource early than described second base station send the second ascending resource time, described subscriber equipment sends the data volume to be sent that BSR, described BSR comprise described subscriber equipment current cache to described first base station; Or,

When described subscriber equipment receives the second ascending resource of described second base station transmission, and described second ascending resource early than described first base station send the first ascending resource time, described subscriber equipment sends upstream data to described second base station, and when described subscriber equipment receives described first ascending resource, described subscriber equipment sends the upstream data amount to be sent that BSR, described BSR comprise described subscriber equipment current cache to this first base station.

Wherein, the data volume to be sent of subscriber equipment current cache can be the upstream data amount to be sent of subscriber equipment buffer memory when triggering BSR, and the upstream data amount to be sent that subscriber equipment first receives the current cache sent when the second ascending resource receives the first ascending resource again can refer to that the upstream data amount to be sent of buffer memory deducts the upstream data amount having sent to the second base station via above-mentioned second ascending resource when triggering BSR.

Such as, during subscriber equipment triggering BSR, the upstream data amount to be sent of buffer memory comprises 100 bytes of LCG1 and 200 bytes of LCG2, and the BSR sent when so first receiving the first ascending resource comprises 100 bytes of LCG1 and 200 bytes of LCG2.When receiving the second ascending resource in the ban, suppose that the upstream data amount sent to the second base station is 150 bytes (comprising 100 bytes of LCG1 and 50 bytes of LCG2), the BSR sent when receiving the first ascending resource so again can only include 150 bytes of LCG2.

Optionally, for the scene first receiving the second ascending resource and receive again the first ascending resource, can be, no matter sent to the upstream data of the second base station whether at wireless spread-spectrum technology (the radio link control of subscriber equipment, being called for short RLC) layer receives status report, do not comprise the upstream data amount having sent to the second base station in this BSR that subscriber equipment sends.Such as, when the first base station is main serving BS, and when the second base station is auxiliary serving BS; Or the first base station provides macrocell (macrocell) to serve, when the second base station provides small-cell (Small cell) to serve, macrocell can be worked in coordination with as subscriber equipment provides service with small-cell.Such as, macrocell provides wide covering, and small-cell provides user data to strengthen; Small-cell to be born user service data or bears part or all of user data service, and macrocell is responsible for control signal.Now, for small-cell provides the second base station of service can be that coverage is smaller, the website that transmitting power is smaller, such as Home eNodeB (Home basestation), micro-base station (pico), remote radio head (Radio remote head is called for short RRH) etc.Now, auxiliary serving BS or the second base station are reliable, the so confirmable upstream data of auxiliary serving BS or the second base station that sends to successfully is sent by subscriber equipment, does not so just need the above-mentioned upstream data again sending transmitting to main serving BS or the first base station.Therefore the data volume that above-mentioned upstream data is corresponding is just not counted in the BSR to the first base station to be sent, so just can reduce the first base station assigns to the ascending resource of subscriber equipment, avoid the wasting of resources causing the first base station.

Optionally, for the scene first receiving the second ascending resource and receive again the first ascending resource, also can be whether receive status report according to the rlc layer of subscriber equipment and determine the BSR to the first base station to be sent.Such as, the upstream data amount sending to the second base station not receiving status report can be comprised in this BSR that subscriber equipment sends to the first base station, and not comprise the upstream data amount issuing the second base station having received status report.Or if the rlc layer of described subscriber equipment does not receive the status report of the corresponding described upstream data sent to described second base station, described BSR also comprises upstream data amount corresponding to the described upstream data sent to described second base station.

Optionally, the upstream data amount do not comprised to the upstream data of the second base station transmission is corresponding as BSR can specifically comprise:

If the wireless spread-spectrum technology rlc layer of described subscriber equipment receives the status report of the corresponding described upstream data sent to described second base station, described BSR does not comprise upstream data amount corresponding to the described upstream data sent to described second base station.

Because rlc layer is normally reliable, when this rlc layer receives status report, data can be shown by transmitting to the second base station, now not comprise the data volume of the upstream data of this transmitting in BSR, the wasting of resources of first resource can be reduced.On the other hand, when rlc layer does not receive status report, the upstream data amount that these upstream datas not receiving status report are corresponding is also comprised in BSR, the first base station assigns can be made can to carry these upstream data amounts to the ascending resource of subscriber equipment, these upstream datas can be transmitted again, improve the reliability of transfer of data.

Because the transfer of data of generally auxiliary serving BS is reliable, like this when being not counted in this partial data in BSR, do not comprise the resource of this part of carrying in the ascending resource that can distribute at main serving BS, so just can reduce the ascending resource that main serving BS distributes, avoid the wasting of resources.

Be understandable that, above-mentioned base station number also can be greater than two, and the scene being greater than two below in conjunction with base station number further describes the present embodiment.

Subscriber equipment also can obtain the actual allocated ratio of each base station and default shunt ratio, the base station that actual allocated ratio can be less than or equal to default allocation proportion by subscriber equipment is defined as the base station sending BSR, and the base station of this transmission BSR can be called selection of base stations.When receiving the ascending resource of selection of base stations transmission in the ban, BSR, this BSR can be sent to this selection of base stations and comprise the upstream data amount pending preparing to send to base station.When receiving the ascending resource of non-selected base stations transmission in the ban, upstream data can be sent to this non-selected base stations, when receiving the ascending resource of selection of base stations transmission afterwards again, BSR is sent to selection of base stations, the upstream data amount of current cache is comprised in this BSR, no matter and whether can receive status report, do not comprise the upstream data amount having sent to the upstream data of non-selected base stations corresponding, or, the upstream data amount that the upstream data sent that do not receive status report is corresponding can also be comprised in this BSR, and do not comprise upstream data amount corresponding to the upstream data sent that received status report.

In the present embodiment, subscriber equipment can send BSR to base station, to realize the transfer of data across base station according to the default shunt ratio obtained and actual shunt ratio.

332: described first base station receives the BSR that described subscriber equipment sends, and described BSR comprises the upstream data amount to be sent of described subscriber equipment current cache.

Optionally, the upstream data amount having sent to the upstream data of the second base station corresponding can not be comprised in this BSR; Or,

Also comprise in this BSR and sent to subscriber equipment in the upstream data of the second base station not receive upstream data amount corresponding to the upstream data of status report.

That is, the present embodiment specifically can comprise above-mentioned 31 and 331, or, specifically can comprise above-mentioned 31,32 and 332.

Wherein, the upstream data amount to be sent of above-mentioned current cache, and the embodiment that the particular content in BSR can be shown in Figure 2, do not repeat them here.

In addition, when the base station number comprised when at least two base stations is greater than two, the flow process that the flow process that the first above-mentioned base station specifically performs can perform see the first base station in Fig. 2 or selection of base stations, the flow process that the flow process that the second above-mentioned base station specifically performs can perform see the second base station in Fig. 2 or non-selected base stations.

The schematic flow sheet of the another kind of means of communication that Fig. 4 provides for the embodiment of the present invention, the present embodiment is to comprise the scene of main serving BS and auxiliary serving BS, and the embodiment of the method corresponding for above-mentioned Fig. 2 and Fig. 3 is specifically described.

In the present embodiment, subscriber equipment can divide into groups to all logic channels, obtains logic channel group, does not configure the incidence relation of logic channel group and base station in advance, and the data of each logic channel group can send to any one base station.

In the present embodiment, the shunt ratio of pre-configured each base station, and this shunt ratio is informed to subscriber equipment, this shunt ratio, for each subscriber equipment, does not distinguish logic channel group and logic channel.

From the shunt ratio of configuration comes into force, subscriber equipment statistics is via the data volume summation of the upstream data of each base-station transmission, when triggering BSR, calculate the transmission data total amount of now recorded each base station, select a ratio lower than the base station of pre-configured shunt ratio, select this base station for sending triggered BSR, this mode can be called leak mechanism.

Suppose that the actual shunt ratio of main serving BS is less than pre-configured shunt ratio, therefore using main serving BS as selection of base stations.After determining selection of base stations, can carry out respective handling according to the sequencing of the ascending resource receiving base station assigns, see Fig. 3, the present embodiment comprises:

41: subscriber equipment triggers BSR, and main serving BS is defined as selection of base stations.42a, 42b or 42c can be performed afterwards.

42a: when receiving the ascending resource of selection of base stations distribution in the ban, send BSR to selection of base stations, comprise the outgoing data amount of all LCG in subscriber equipment.

In the present embodiment, when namely receiving the ascending resource of main serving BS distribution in the ban, subscriber equipment sends BSR to main serving BS, comprises the 100 byte data amounts of LCG1 and the 200 byte data amounts of LCG2.

42b: when receiving the ascending resource of non-selected base stations distribution in the ban, user sends upstream data to this non-selected base stations, when after transmission upstream data, if there are remaining data, then when receiving the ascending resource that selection of base stations distributes, send BSR to selection of base stations.The outgoing data amount comprised in this BSR depends on wireless spread-spectrum technology (the Radio Link Control of subscriber equipment, RLC) whether layer receives status report, the above-mentioned upstream data having received status report is not counted in BSR, only counts the part upstream data not receiving status report.

In addition, the ascending resource distributed when non-selected base stations is enough large, when there are not remaining data after non-selected base stations transmission upstream data, BSR cancelled by subscriber equipment, and so subscriber equipment also can not send BSR when receiving the ascending resource that selection of base stations distributes.

Such as, the upstream data corresponding to outgoing data amount of subscriber equipment current cache comprises outgoing data amount 100 byte of LCG1 and outgoing data amount 200 byte of LCG2.When subscriber equipment first receives the ascending resource of auxiliary serving BS distribution, subscriber equipment sends upstream data according to ascending resource to auxiliary serving BS, suppose that this upstream data comprises 100 bytes of LCG1 and 50 bytes of LCG2, namely send the data of 150 bytes to auxiliary serving BS.

Afterwards, when receiving the ascending resource that main serving BS distributes, subscriber equipment sends BSR to main serving BS, suppose the upstream data for having sent, subscriber equipment does not receive status report, then can comprise outgoing data amount 100 byte of LCG1 and outgoing data amount 200 byte of LCG2 in this BSR.Or if for the upstream data sent, subscriber equipment all have received status report, then only comprise outgoing data amount 150 byte of LCG2 in this BSR.

42c: when subscriber equipment first receives the ascending resource of non-selected base stations distribution, upstream data is sent to this non-selected base stations, when after transmission upstream data, if there are remaining data, then when receiving the ascending resource that selection of base stations distributes, send BSR to selection of base stations, and the data volume sent is not counted in BSR.

With 42b unlike, after subscriber equipment sends the data of 150 bytes to auxiliary serving BS, no matter whether receive status report, the data of this 150 byte are all not counted in BSR, namely only comprise the 150 byte data amounts do not sent of LCG2 in BSR.

51: the first base stations and the second base station negotiate subscriber equipment send the default shunt ratio of upstream data.

Optionally, Signalling exchange can be passed through in the first base station and the second base station, consults to determine respective default shunt ratio.

52: described first base station receives the BSR of described subscriber equipment transmission and is transmitted to described second base station, be described user equipment allocation ascending resource for described first base station and described second base station according to described default shunt ratio and described BSR, wherein, described BSR comprises the data volume to be sent of described subscriber equipment current cache.

Optionally, described first base station receives the BSR of described subscriber equipment transmission and is transmitted to described second base station, specifically comprises:

Optionally, the method can also comprise:

Such as, when the first base station is after user equipment allocation ascending resource, the upstream data of 50 bytes of BSR and LCG1 that the first base station receives user equipment sends via this ascending resource.This BSR comprises 100 bytes of LCG1 and 200 bytes of LCG2.Suppose that the default shunt ratio of the first base station and the second base station is respectively 30% and 70%, so, the first base station sends to the BSR of the second base station can comprise (100-50) * 70%=35 byte of LCG1, and the 200*70%=140 byte of LCG2.

Now, owing to not comprising the upstream data amount sent, so the first base station sends to the BSR of the second base station can comprise less data volume, so can reduce the second base station follow-up for this BSR distribute to the ascending resource of subscriber equipment, reduce signaling and resource overhead.

Optionally, because main serving BS is more stable in general, subscriber equipment sends to main serving BS the reliability that BSR can improve transfer of data, and the first above-mentioned base station can be main serving BS, and the second base station can be auxiliary serving BS.

In the present embodiment, subscriber equipment can divide into groups to all logic channels, and obtain logic channel group, and do not configure the incidence relation of logic channel group and base station in advance, the data of each logic channel group can send to any one base station.

In the present embodiment, the shunt ratio of pre-configured each base station, and not shunt ratio described in notifying user equipment.Above-mentioned shunt ratio is only consulted between base station, and this shunt ratio is for each subscriber equipment, does not distinguish logic channel group and logic channel.

Subscriber equipment triggers after BSR, and the ascending resource first receiving which base station assigns just sends BSR to which base station, receive BSR base station can: according to pre-configured shunt ratio, the BSR after filtration is informed to another base station; Or do not filter, directly the BSR of reception is transmitted to another base station, each base station calculates the data volume oneself needing to bear separately, makes scheduling decision.

In the present embodiment, described subscriber equipment sends BSR to the first base station, described BSR comprises the outgoing data amount of all logic channel groups in described subscriber equipment, described first base station sends BSR to the second base station, and described first base station comprises the outgoing data amount of all LCG in described subscriber equipment to the BSR that the second base station sends, or, the outgoing data amount of each LCG that described first base station comprises to the BSR that the second base station sends is β × A, wherein, β is the shunt ratio of the second pre-configured base station, A=A ₀or, A=A ₀-a, A ₀be the outgoing data amount of the corresponding LCG comprised in the BSR of the first base station reception, a is the upstream data amount that subscriber equipment sends in the lump when sending BSR to the first base station.

The present embodiment supposes that the shunt ratio of main serving BS and auxiliary serving BS is respectively 30% and 70%, and subscriber equipment first receives the ascending resource that main serving BS distributes.

See Fig. 7, the present embodiment comprises:

71: subscriber equipment triggers BSR.Afterwards, 72a, 72b or 72c can be performed.

72a: after subscriber equipment receives the ascending resource of main serving BS distribution, BSR is sent to main serving BS, comprise the outgoing data amount of all LCG, main serving BS sends BSR to auxiliary serving BS, this BSR is the BSR after the filtration determined according to shunt ratio, and comprises subscriber equipment when filtering and sent to the data volume that the upstream data of main serving BS is corresponding.

Such as, after subscriber equipment receives the ascending resource of main serving BS distribution, outgoing data amount 100 byte of LCG1 and outgoing data amount 200 byte of LCG2 is comprised in the BSR that main serving BS sends, and, the data of 50 bytes of LCG1 are also transmitted to main serving BS.Suppose that the default shunt ratio of main serving BS and auxiliary serving BS is 30% and 70%.

After main serving BS receives this BSR, filter according to shunt ratio, auxiliary serving BS is sent to after namely the data volume of each LCG being multiplied by 70% respectively, wherein, the data volume comprising 50 bytes reported when calculating the data volume of LCG1, namely be multiplied by 70% by 100 bytes of LCG1, therefore, main serving BS sends to outgoing data amount 140 byte of outgoing data amount 70 byte and the LCG2 comprising LCG1 in the BSR of auxiliary serving BS.

72b: after subscriber equipment receives the ascending resource of main serving BS distribution, BSR is sent to main serving BS, comprise the outgoing data amount of all LCG, main serving BS sends BSR to auxiliary serving BS, this BSR is the BSR after the filtration determined according to shunt ratio, and does not comprise subscriber equipment when filtering and sent to data volume corresponding to the upstream data of main serving BS.

With 72a unlike, main serving BS is the data volume not comprising 50 bytes reported when calculating the data volume of LCG1, (100-50) byte of LCG1 is namely used to be multiplied by 70%, therefore, main serving BS sends to outgoing data amount 140 byte of outgoing data amount 35 byte and the LCG2 comprising LCG1 in the BSR of auxiliary serving BS.

Now, the second upstream data can be given, to reduce the burden of the first base station by the second base station assigns ascending resource.After subscriber equipment receives the first ascending resource of the first base station assigns, described subscriber equipment sends described first upstream data to described first base station, does not send described second upstream data; Or described subscriber equipment sends described first upstream data and described second upstream data according to actual conditions to described first base station.

Optionally, described first base station is main serving BS, and described second base station is auxiliary serving BS, to improve data transmission credibility.

Optionally, when described BSR comprises the data volume of corresponding described first upstream data, described subscriber equipment sends SR to described main serving BS.

Owing to main serving BS there being special Physical Uplink Control Channel (physical uplink controlchannel, PUCCH), so subscriber equipment can be configured in the SR resource on main serving BS.Auxiliary serving BS generally only has hybrid automatic repeat-request (hybid automatic repeat request, HARQ) feed back and just can take public PUCCH.Therefore, subscriber equipment sends SR to main serving BS.

Be understandable that, above-mentioned for two base stations, the scene being greater than two for base station number below further describes the present embodiment.

First upstream data of the first logic channel group can only send to the first base station, and it is to the first base station that the BSR comprising data volume corresponding to the first upstream data also can only send out.This first base station or other arbitrary base station can be sent to for the data of other logic channel group and BSR.In addition, subscriber equipment only asks BSR, this BSR to comprise data volume corresponding to the first upstream data to main serving BS transmission SR.

In this method embodiment, the logic channel group of the high priority of subscriber equipment and the first base station association, the upstream data of this logic channel group can only send to the first base station, the upstream data of all the other logic channel groups can send to the first base station or the second base station, to realize the transfer of data between subscriber equipment and base station.
