Referring to the drawings 1 to Fig. 2, the embodiment of the present invention is described in detail from the angle of systems approach：
First embodiment
Fig. 1 belongs to base station according to the specific embodiment of the present invention（Or Node B) la UE 4a and 4b receive base station la, lb cooperated with base station 3 provide MBMS topology network schematic diagram.Wherein, UE 4a and 4b is in the edge of base station la jurisdiction districts, and it is respectively also in base station 3 and base station lb coverage；UE 4c are in the edge of base station lb jurisdiction districts, in its coverage also in base station la；Base station la, lb and the jurisdiction district of base station 3 are in a hybrid cell cluster using single cell transmission pattern（The cell cluster of the cell composition of unicast and broadcasting multicast service is provided）In, the cell cluster and then belong to an identical service area（ Service Area );Also include multi-base station cooperative server 2 in the cordless communication network, the multi-base station cooperative server 2 may be integrally incorporated to the multiple cell multicast coordination entity of wireless network（Multi-cell/multicast Coordination Entity, abbreviation MCE) in, the MCE can be a self-existent network equipment, can also it is integrated in a base station, it is communicated between base station la, lb and base station 3 based on the existing M2 interfaces between MCE and base station；The cordless communication network also includes a MBMS gateway（Not shown in figure）, it is used to provide MBMS data to base station la, lb and base station 3 by Ml interfaces；A cell is only had jurisdiction in each base station in the present embodiment.It is appreciated that the present invention is not limited under network topology and device configuration shown in Fig. 1, other topological structures and device configuration, the present invention is equally used.Also, MBMS is provided the invention is not restricted to multi-base station cooperative, and goes for providing other any broadcast and/or multicast service.
Fig. 2 shows a specific embodiment according to the present invention, base station la, multi-base station cooperative server 2 and base station 3 auxiliary UE4a and 4b receive base station la cooperated with base station 3 offer MBMS business method flow chart.
Below with reference to Fig. 1 and Fig. 2, to according to the present invention, base station la, multi-base station cooperative server 2 and the auxiliary UE4a of base station 3 receive base station la with 4b and cooperated with base station 3 to provide MBMS industry The method of business is described in detail.
First, in step slo, base station la obtains the adjacent cell communication quality information between the base station of its respective neighbor cell of UE 4a and 4b, and obtains this cell communication quality information between the respective la with this base station of UE 4a and 4b.
Specifically, in one case, based on single cell transmission service, base station la can be to the UE for receiving the MBMS broadcast measurement control messages belonging to it.The information such as measurement object, report rule can be included in the measurement control message, measurement object can include this base station to the channel quality parameter (Channel Quality Indicator, abbreviation CQI) and the reception signal reception power of the neighbor cell of the user equipment of the user equipment（RSRP) etc..
Control message is then measured by the broadcast, base station la indicates that its own base station is returned in the base station that each UE is measured belonging to it to its channel quality, and by the channel-quality feedback.Thus, the UE 4a and 4b in cell edge will use certain metering system, for example, the preceding paragraph in its downstream signal is sent to by base station la（Preamble), the information such as pilot tone, measurement obtains base station la to its downlink communication shield amount, such as signal to noise ratio, Signal to Interference plus Noise Ratio, and provides it to base station la.
Also, base station la indicates also to indicate that each UE measures the reception signal reception power of its neighbor cell.Because UE 4a and 4b are in cell edge, it is also in the base station of neighbor cell, such as coverage of base station 3 and base station lb signal, and it also passes through the reference symbol receiving power of neighbor cell（RSRP its each downlink communication quality between the base station lb of neighbor cell and base station 3, and provide it to base station la) is measured.
It is worth noting that, present invention is directed primarily to the MBMS service performances for the UE for improving cell edge area, the UE that center of housing estate area can thus be needed not be at provides its communication quality information, and its communication quality is useless to multi-base station cooperative MBMS.Then, to avoid the upward signal congestion in cell, preferably, base station la can set 4 blunt announcement threshold values in the report rule of measurement control message, UE is only receiving neighbor cell signal, and the signal quality is more than after the set wealthy value of report, just accuse its communication quality between adjacent base station and the UE own base stations is just blunt to own base station.Also, in view of UE mobility, spent to avoid ping-pong (Pin-pong effect) and reducing signal, the present invention, which can also be set, to be used hysteresis mechanism to improve accuracy of measurement. And in another case, in symmetric channel, or estimable nonsymmetric channel, base station la can the upward signal based on UE 4a and 4b, determine base station la to UE 4a and 4b down channels signal quality；The base station 3 of UE 4a and 4b neighbor cell and base station lb can be respectively according to UE 4a and 4b to its upward signal simultaneously, base station 3 and base station lb to UE 4a and the down channel quality of 4b equipment are determined, and the channel quality is supplied to base station la.
Shellfish ' J, in step slo, base station la obtains the adjacent cell communication quality information between the base station of its respective neighbor cell of UE 4a and 4b, and obtains this cell communication quality information between the respective la with this base station of UE 4a and 4b.
Then, in step S11, base station la is according to the adjacent cell communication quality information between the base station of its respective neighbor cell of UE 4a and 4b and this cell communication quality information between the la of this base station, multi-base station cooperative information is determined, and the broadcast of base station la jurisdiction districts and/or the offer status information of multicast service are provided.
Specifically, base station la is according to UE 4a and the respective adjacent cell communication quality informations of 4b, it is determined that wherein communication quality preferably one or more neighbor cells are cooperation cell.For example, can be according to maximum and most principles（Max Most) selected, and determine cooperation cell amount threshold n, that is, cover n best neighbor cell of adjacent cell communication qualities of the UE at most and between each covering UE in this cell can as this base station cooperation cell.In the present embodiment, think that base station 3 is more than base station lb to UE 4b RSRP to UE 4a RSRP, and number of cells threshold value is 2, then base station la can be using base station 3 and base station lb cell as its cooperation cell, and base station 3 and base station lb is used as its cooperative base station.It is worth noting that; in real network; UE quantity may be greatly increased; cooperation cell amount threshold be able to may also change; the strategy of simultaneous selection cooperation cell may also be distinct from that above-mentioned maximum and most principles; persons skilled in the art can suitably be adjusted according to performance, but this is all in protection scope of the present invention.
Simultaneously, in one case, base station la is always according to UE 4a and the worst communication quality information of respective cell communication quality of 4b, such as minimum CQI, determine that base station la provides the modulation coding mode of MBMS to administrative UE, to ensure that the worst UE of communication quality also can extract MBMS business datums from the signal of the use of reception modulation coding mode processing. The relevant information of above-mentioned selected cooperation cell, foregoing multi-base station cooperative information is may be constructed with this base station la of determination modulation coding modes for providing MBMS business.
And in another case, base station la regard UE 4a and the worst communication quality information of respective cell communication quality of 4b as foregoing multi-base station cooperative information with the relevant information of selected cooperation cell.In this case, multi-base station cooperative server helps to carry out the selection of MBMS modulation coding mode.
It is worth noting that, in the present embodiment, UE 4a are only adjacent with a neighbor cell respectively with 4b.It is appreciated that in other topological structures or real network, user equipment can be in the coverage of multiple neighbor cell base stations, then its own base station can obtain each neighbor cell to the communication quality of user equipment simultaneously.This situation is also within the present invention and scope of the claims.
And, base station la also determines the offer status information of the MBMS of its jurisdiction district, specifically, the offer status information can include the sequence number of the packet of the MBMS of this base station la current transmissions, and this information can be in order to the transmission of multi-base station cooperative server sync MBMS packets.
Then, in step S12, the multi-base station cooperative information of determination is sent to multi-base station cooperative control server 2 by base station la with the MBMS status informations of this base station la jurisdiction districts.Specifically, can be by carrying out necessarily extending and reusing to the M2 interfaces between existing MCE and base station, to transmit these information to multi-base station cooperative control server 2.
It is similar with above step, base station lb can also be according to its administrative cell edge UE 4c, the jurisdiction district for determining base station la is its cooperation cell, and by its multi-base station cooperative information, multi-base station cooperative control server 2 is sent to the MBMS status information of jurisdiction district.It is worth noting that, if also including the base station that other UE for aiding in this cell carry out MBMS in base station la, lb and cell cluster belonging to base station 3, so it also carries out similar step, and providing status information by its multi-base station cooperative information and MBMS is sent to multi-base station cooperative control server 2.
Then, in step S20, multi-base station cooperative control server 2 receives the respective multi-base station cooperative information from base station la Yu base station lb, the MBMS business state informations of the serving cell administrative with it. Then, in step S21, multi-base station cooperative controls server 2 according to base station la and base station lb respective multi-base station cooperative information, the MBMS status information of the serving cell administrative with it, base station la and base station lb cell base stations adjacent thereto respective multi-base station cooperative mode are determined, the offer status information that cooperates with MBMS.
In one case, base station la and base station lb multi-base station cooperative information includes the cooperation cell information that it is each determined, MBMS modulation coding mode is provided with it.
Because the multiple base stations for participating in multi-base station cooperative MBMS need to use identical modulation coding mode（Modulation and Coding Scheme, abbreviation MCS), then in step S210, selection communication capacity is minimum during multi-base station cooperative controls the modulation coding mode that server 2 provides MBMS from base station la and base station lb, the minimum modulation coding mode of such as information rate is as public cooperate modulation coding modes of the base station la with base station lb, to ensure that the worst UE of communication quality also can extract MBMS data from the signal handled according to the cooperation modulation coding mode.Specifically, multi-base station cooperative control server 2 setting base station la, lb and base station 3 all use a kind of identical MCS.
And in another case, base station la and base station lb multi-base station cooperative information includes its cooperation cell information each determined, and base station la and respective worst this cell communication quality informations of base station lb.
Due to same principle, multi-base station cooperative control server 2 need to determine public cooperation modulation coding mode according to each worst communication quality.Specifically, because when the base station of own base station and cooperation cell sends MBMS to UE simultaneously, UE can obtain merging gain, therefore can equally obtain higher communication quality.Around this principle, in step S210', multi-base station cooperative controls server 2 to consider each cooperation cell in each cooperation cell information to each UE communication quality, with the communication quality of each base station to each UE, using certain algorithm, for example according to base station and the multichannel communication multiple telecommunication quality of cooperative base station to the UE, it is determined that to UE equivalent communication path quality, then according to equivalent communication path quality worst in each UE, determine a suitable public cooperation modulation coding mode, so as to ensure that the worst UE of equivalent communication quality also can extract MBMS data from the use of reception in the signal of public modulation coding mode processing..It is not the category that the present invention is discussed specifically to determine public modulation coding mode algorithm, and persons skilled in the art can be according to existing Technology, realizes this purpose.
Also, in step S211, multi-base station cooperative control server 2 is that base station la and base station lb cooperates therewith the communication resource that cell base station determines its respective offer MBMS, wherein, base station la cooperation cell base station is base station 3 and base station lb;Base station lb cooperation cell is base station la.Wherein, multi-base station cooperative control server 2 can carry out communication resource distribution based on following two modes：
(1) classes SFN, in this mode, multi-base station cooperative control server 2 is base station la, lb for being operated under single cell transmission pattern and when identical all distribute in base station 3/frequency resource block transmits identical MBMS signals.The signal of the MBMS of each cell can be overlapped mutually naturally in the air, and less radio-frequency is provided to user equipment（RF) merge gain, the UE of the cell edge of single cell transmission pattern can so obtained and merges gain.Specifically, multi-base station cooperative control server 2 is interacted with each base station, its resource allocation conditions is obtained, when finally determining public/frequency resource.
(2) soft mergings, in this mode, and when need not be for base station la, lb and the distribution identical of base station 3/frequency resource block, when each cell uses suitable according to the state of oneself/frequency resource transmission MBMS.UE can obtain multiple signals, and carry out maximum-ratio combing（Maximum Ratio Combination, abbreviation MRC) to obtain soft merging gain.Specific soft merging technology is that known to persons skilled in the art, the present invention does not do excessive narration.This resource distribution mode may cause certain interference to the UE that adjacent cell is communicated using same transmission resource.
Then multi-base station cooperative mode includes determining cooperation modulation coding mode, and the respective communication resource for providing MBMS of cell base station is cooperated therewith with multiple base stations.
And, with above S210 or S210' and S211 irrelevantly, in step S212, multi-base station cooperative control server 2 determines that the cooperation of MBMS provides status information, specifically, the MBMS status information that base station la, lb are provided includes the packet sequence number for the MBMS that respective base station was transmitted at that time；Multi-base station cooperative control server 2 can also obtain the MBMS transmitted of base station 3 packet sequence number.Then its MBMS at that time provided according to each base station packet sequence number, determines that each base station starts cooperation and carries out MBMS transmission starting point, the start sequence number and initial time of such as packet, the start sequence number should be than each base stations All sequence numbers that it was transmitted at that time provided are all big, and initial time should be identical under the conditions of class SFN, and initial time can be different under the conditions of soft merging.The cooperation provides status information and can further include the transmission cycle of packet etc. information.
It is worth noting that, multi-base station cooperative control server 2 may be according to certain strategy, for example state is provided according to each cooperation cell MBMS at that time, the base station that part actual participation cooperates is selected from base station la with the base station lb cooperative base stations provided, and not necessarily the cooperative base station fully according to its offer determines cooperation mode.
Then, in step S22, multi-base station cooperative controls server 2 by the multi-base station cooperative mode of determination, and the cooperation with determining MBMS provides status information and is sent to corresponding described base station la, lb and cooperation cell base station 3 by M2 interfaces.The angle from base station 3 is illustrated below, it is evident that base station la is similar with the lb work carried out.
It is appreciated that, because base station has power to make decision to the data communication in jurisdiction district, multi-base station cooperative control server 2 preferably can also hold consultation with each base station, determine whether the base station is unified by multi-base station cooperative mode, and MBMS business is provided with the offer status information that cooperates of MBMS business.And the multi-base station cooperative mode that each base station preferably also can control server 2 to provide according to multi-base station cooperative cooperates with MBMS and provides status information, it is made whether to participate in the decision of multi-base station cooperative, and is determined to feed back to multi-base station cooperative control server 2.In this case, accordingly, multi-base station cooperative control server 2 and each base station should also carry out above-mentioned the step of hold consultation and make decision, and to these steps, the present invention is not further described.
In step s 30, base station 3 receives the multi-base station cooperative mode that server 2 is controlled from multi-base station cooperative, the offer status information that cooperates with MBMS.
Specifically, multi-base station cooperative mode includes cooperation modulation coding mode, the communication resource with providing MBMS, such as running time-frequency resource.
And the cooperation of MBMS provides the start sequence number and initial time that status information includes the packet of transmission MBMS.
Then in step S31, base station 3 is in the initial time, since the packet of the corresponding MBMS of the start sequence number, coded treatment is modulated to the packet of MBMS by cooperation modulation coding mode, and the MBMS is provided to UE using the running time-frequency resource. The MBMS data can be obtained by Ml interfaces from MBMS gateways in advance by base station 3.
Similar, in step S13 and S14, base station la controls the multi-base station cooperative mode that server 2 is provided according to multi-base station cooperative, and the cooperation of MBMS business provides status information and provides MBMS to UE.Base station lb also carries out similar operations.
Certainly base station may be stilled need there is provided MBMS process to interact with UE, to inform how UE receives the MBMS signals that multiple base stations are sent.This is that known to persons skilled in the art, the present invention is not repeated this.
For UE 4a, it is received from affiliated base station la and both the MBMS signals of base station 3, and carries out corresponding merging treatment, obtains MBMS data.Equally, UE 4b have also obtained MBMS performance boosts with 4c under base station la cooperations with base station lb.By the present invention, the MBMS service performances of the Cell Edge User equipment under single cell transmission pattern are improved.
It is worth noting that, in the embodiment above, because base station la, lb and 3 are in mutually adjacent position, its MBMS business can interact, then it is each base station selected common modulation coding mode that multi-base station cooperative, which controls server 2, MBMS cooperations provide status information etc..It is appreciated that, server 2 is controlled to be multigroup cell serves in cell cluster in multi-base station cooperative, it will not be interacted between multigroup cell simultaneously, for example when the MBMS business of each group Ge Group of relatively far apart will not interact, it should be respectively the multi-base station cooperative mode that this group of cell is determined in each group cell, including public modulation coding mode and resource distribution mode etc..In scope of the claims of the such case similarly in the present invention.
It is appreciated that the multi-base station cooperative relation of the above can dynamically change.When the cooperation shield amount of base station minizone adjacent thereto changes, above step can be re-started.To obtain in real time preferably multi-base station cooperative mode, then more preferable multi-base station cooperative service is provided to user equipment.The specific embodiment of the system according to the present invention method is had been described in detail above.The embodiment of the present invention will be described in detail from the angle of system and device below.
