Description

A kind of ascending macro diversity combining method, Apparatus and system

Technical field

The present invention relates to the grand diversity folding of wireless communication system, particularly a kind of ascending macro diversity combining method, Apparatus and system.

Background technology

Universal mobile telecommunications system (UMTS) is to adopt Wideband Code Division Multiple Access (WCDMA) to insert the 3-G (Generation Three mobile communication system) of (WCDMA) air interface technologies.Fig. 1 is the composition structural representation of existing UMTS system.Referring to Fig. 1, the UTMS system comprises: subscriber equipment (UE), UMTS Terrestrial radio access network (UTRAN) and core net (CN).

In the system shown in Figure 1, UTRAN is the Radio Access Network (RAN) of UMTS, is used to handle all and wireless function associated;

Comprise one or more RNSs (RNS) among the UTRAN, and each RNS is made up of a radio network controller (RNC) and one or more base station (NodeB); Wherein, RNC is used to distribute and is attached thereto with control or the Radio Resource of relevant NodeB, and NodeB is used to finish the conversion of the data flow between Iub interface and the Uu interface, and the while also participates in a part of RRM; Interface between RNC and the CN is the Iu interface, and the interface between NodeB and the UE is the Uu interface, is connected by Iub interface between RNC and the NodeB, and is interconnected by Iur between each RNC, and Iur can connect or connect by transmission network by the direct physical between the RNC;

CN is responsible for handling voice calls all in the UMTS system and is connected with data, and the exchange of realization and external network and routing function; The network entity that comprises among the CN has mobile switching center (MSC/VLR), service general grouping service wireless support point (SGSN), attaching position register (HLR), GPRS mobile switching centre (GMSC) and Gateway GPRS Support Node (GGSN).

Grand diversity is meant at code division multiple access and inserts in the soft switching process of (CDMA) system, and UE communicates by two or many different Radio Links with two or more base stations simultaneously, and here, the set of the base station that UE connects simultaneously is called Active Set.Grand diversity can be brought macro diversity, the antijamming capability of enhanced system, and its basic principle is: under separate propagation conditions, the probability of identical deep fade takes place in the probability that deep fade takes place several signals simultaneously less than individual signals.For example, UE is simultaneously when identical signal is transmitted in two base stations, because the path difference of signal transmission, thus can think that the decline of these two signals is separate, that is: during a signal generation deep fade, the probability that deep fade takes place another signal simultaneously is very low, so, carry out suitable selection at receiving terminal, for example, select better one road signal output of signal quality, then the signal to noise ratio of system will be improved.

In existing UMTS system, the realization that grand diversity merges (MDC) is: for up link, base station in the Active Set all receives the data on the UE Code Channel, and the data that received are sent to RNC select to merge, for example, RNC can use frame reliability instruction character to select preferable frame in a plurality of candidate frame, and the preferable frame that will select then merges, and sends to core net; For down link, the base station in the Active Set is simultaneously to the identical signal of UE emission.

It is the WCDMA evolvement network that third generation partner program (3GPP) proposes that the high-speed packet of evolution inserts (E-HSPA/HSPA+), has at present among multiple possible evolution HSPA architectural schemes discussing.In the HSPA of evolution, different in the mode of realization MDC and the UMTS system.

Fig. 2 has the method schematic diagram of realizing uplink macro diversity in a kind of possible E-HSPA network now.Referring to Fig. 2, the HSPA+ base station of evolution (Node B+) is the base station equipment in the evolution HSPA network, and xGSN represents the combination of SGSN and GGSN, represents core net in the HSPA network; Iur interface by strengthening between the NodeB+, promptly Iur ' interface links to each other, and each Node B+ inserts core net by the standard I u interface.Access Network part in network shown in Figure 2, Node B in original 3G network and RNC two node structures are evolved to the single node structure of having only a Node B+, and the function of RNC all moves down among the Node B+.In the evolvement network shown in Figure 2, up MDC realizes in user's Serving cell Node B+, for the data on all Radio Links in the Active Set, if the reception data on the Radio Link of certain base station correspondence are correct, then this base station sends to this Serving cell NodeB+ with upstream data, and Serving cell Node B+ carries out sending to core net after the grand diversity merging processing to received upstream data.This scheme is similar to the realization of MDC among the existing RNC of 3G system, and just the position that function is realized moves down on the Serving cell NodeB+ from RNC.

By the implementation procedure of MDC in the above-mentioned evolvement network as seen, if evolution network framework is realized flattening, then the function of RNC need move down among the Node B+, and base station node B+needs that mean enhancing are the access core net directly.Under the situation that keeps terminal UE and Iu interface backward compatibility, if on Serving cell NodeB+, realize uplink macro diversity, then must need mutual communication between each Node B+, if carry out centralized grand diversity processing all up reception transfer of data for this Serving cell Node B+ and allow all receive the correct soft handover base station of data, then will there be bulk redundancy information in the received data of Serving cell Node B+, these redundant transmission there is no need, and will increase the load of interface between the base station.

In addition, for the network of the Internet Protocol (IP) that adopts do not guarantee service quality (QoS) as the networking agreement, the HSPA business of big data quantity will make that the loading problem between the base station is particularly outstanding.

Embodiment

For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.

The main thought of the embodiment of the invention is when the received data of base station in service sector are correct, the data that directly that it is the received data of Serving cell merge as uplink macro diversity are carried out grand diversity and are merged processing, and when the received data of base station in service sector are incorrect, determine to carry out the non-service cell base station that data send by base station in service sector, and notice relevant base station transmission data, make and realize giving when uplink macro diversity merges the redundant transmission amount of bringing between the base station to significantly reduce.

Technical solution of the present invention can be applied in multiple wireless evolution network and the prior wireless network, and related base station is the base station equipment in the evolvement network in the embodiment of the invention, can be the Long Term Evolution base station (eNodeB) of NodeB+ or evolution.

Fig. 3 is the exemplary process diagram of ascending macro diversity combining method in the embodiment of the invention.Referring to Fig. 3, this method may further comprise the steps:

Step 301: when base station in service sector judged that the received data in this base station are correct, the data that this base station is received were handled as the data of up MDC.

In this step, base station in service sector is at first judged the correctness of the data that himself is received, when base station in service sector judges that the received data in this base station are correct, directly that it is the received data of Serving cell are handled accordingly as the data that uplink macro diversity merges, and by sending the instruction that expression does not send data to the non-service cell base station, perhaps do not respond the data sending request that send the non-service cell base station, send data to base station in service sector or core net again to avoid the non-service cell base station.

Step 302: when base station in service sector judges that the received data in this base station are incorrect, determine to carry out the non-service cell base station that data send.

In this step, when base station in service sector judges that the received data in this base station are incorrect, from receive the correct non-service cell base station of data, select one as data transmission base station, notify it to send data to base station in service sector or core net, for example, can perhaps by not sending the instruction that expression does not send data, notify corresponding non-service cell base station to carry out data and send by responding the data sending request of certain non-service cell base station to any non-service cell base station.

In this step, merge owing to have only the correct data of verification can selectedly carry out uplink macro diversity, therefore, the non-service cell base station needs to carry the information that relevant base station receives data correctness in the data sending request that base station in service sector sent.Therefore, in embodiments of the present invention, all can characterize the content that receives data correctness information all can be as the content of data sending request in this step, and few and many persons of amount of information are good with data volume.For example, the content of data sending request can be cyclic redundancy check (CRC) check results, uplink signal-channel quality characteristic or the user performance information etc. of Frame.

In this step, when specified data sends the non-service cell base station, the instruction that the expression that is sent or not or data sending request/response etc., these Signalling exchanges can be carried on (inband) message in the band, also can be carried on outer (out-of-band) message of band.

In this step, the instruction that the expression of sending for base station in service sector does not send, and the data sending request/response between base station in service sector and the non-service cell base station can be by optimizing transmission and improving priority and reduce time delay.

Make base station in service sector to carry out distributed selection by this request in this step or instruction to the reception data of each non-service cell base station, be different from the centralized selection of prior art, can greatly reduce the redundant transmission amount between the base station.

Step 303: be determined the non-service cell base station of carrying out the data transmission and send the received data in this base station.

In this step, the non-service cell base station does not send the instruction of data according to the expression that comes from base station in service sector, and perhaps the data returned of base station in service sector send response, judge whether himself is to be determined to carry out the non-service cell base station that data send.The expression that comes from base station in service sector for wait does not send the non-service cell of data command, the timer that an expression sends the received data in this base station can be set, the data check that is received when certain non-service cell base station correct and after this timer expiry, do not receive as yet come from base station in service sector do not send instruction, then this non-service cell base station can judge that the data that Serving cell receives are incorrect, therefore, this non-service cell base station judges that this base station is the base station that data send of carrying out that is determined.

In this step, the mode that non-service cell sends the received data in this base station has two kinds, and a kind of is this base station to be received correct data send to base station in service sector, by base station in service sector these data is carried out uplink macro diversity then and merges processing; Another kind is that each the bar link in the UE Active Set all is that a GPRS tunnel passage (GTP) on the Iu interface is set up in this communication of this UE, simultaneously, core net is safeguarded the correspondence relationship information of this UE and many GTP passages, when the non-service cell base station determines that this base station is carrying out of the being determined base station that data send, is connected directly that this base station reception is correct data by this base station and Iu interface between the core net and sends to core net.

Step 304: the data that non-service cell sends are handled as the data of up MDC.

In this step, if carrying out the equipment of up MDC processing is base station in service sector, then in step 303, be determined the non-service cell that carries out the data transmission and will send to base station in service sector to data, when base station in service sector receives the identical data that comes from a plurality of non-service cells, can therefrom select data to carry out up MDC and handle;

If carrying out the equipment of up MDC processing is core net, then in step 303, be determined the non-service cell base station of carrying out the data transmission and correspondingly should send to core net to data, and core net also can select data to carry out up MDC processing from a plurality of identical datas that receive.

In this step, the concrete mode and the prior art of fixed data being carried out up MDC processing are similar, do not repeat them here.

So far, finish the exemplary flow of ascending macro diversity combining method in the embodiment of the invention.

Below in conjunction with accompanying drawing, the present invention is described in detail to lift four specific embodiments:

Embodiment one:

In the present embodiment, the non-service cell base station does not initiatively send to base station in service sector and receives correct data under the assumed by default situation, therefore, judge in the non-service cell base station when reception data on the Radio Link of himself correspondence are correct, initiate data sending request to base station in service sector, when receiving data transmission response from base station in service sector, send the correct data of reception to base station in service sector.

Fig. 4 is the schematic flow sheet of the system of selection in the uplink macro diversity data in the embodiment of the invention one.Referring to Fig. 4, this method may further comprise the steps:

Step 401: base station in service sector judges whether himself received data is correct, if correct, continues execution in step 402; Otherwise, continue execution in step 403.

In this step, base station in service sector can be checked the correctness that receives data on himself Radio Link according to prior art, when assay is correct for receiving, continues execution in step 402; Otherwise, continue execution in step 403.

Step 402: base station in service sector selects reception data on the Radio Link of himself correspondence as correct data, participates in uplink macro diversity and merges, and finishes the present embodiment method flow.

In this step, base station in service sector is defined as the reception data on the Radio Link of himself correspondence can handle these data according to existing grand diversity folding, and the data after will handling to be uploaded to core net by the Iu interface after the correct data.

Step 403: receive the correct non-service cell base station of data and send data sending request to base station in service sector.

Because in the present embodiment, the non-service cell base station does not initiatively send to base station in service sector and receives correct data under the default situations, therefore, in this step, non-service cell base station in Active Set is through check, when the data that Radio Link received of determining this sub-district are correct, initiate data sending request to base station in service sector.Carry in this data sending request and can characterize the content that receives data correctness information, for example, the CRC check result of Frame, uplink signal-channel quality characteristic or user performance information etc. all can be used as the content of this data sending request, and few and many persons of amount of information are good with data volume.

In this step, in-band information can be passed through in the non-service cell base station, also can send data sending request to base station in service sector by the band external information, and promptly data sending request can be carried on in-band information or band external information.Wherein, the mode of carrying by the band external information can be the new signaling message of definition, for example, can define new Radio Network Subsystem Application Part (RNSAP) signaling message as data sending request on the Iur interface; The mode of carrying by in-band information can be the type of expansion existing channel frame or utilize the unused word section in the existing channel frame to carry data sending request.Here, the unused word section in the channel frame is meant does not have the field used in the channel frame, comprises reserved field (Spare), reserves extended field (Spare Extension) or other can be used to carry the field of data sending request of the present invention.

During by band external information carrying data sending request, can be according to certain formal definition new signaling message gets final product its related specifications that meets signaling message on the Iur interface, does not repeat them here.For situation by in-band information carrying data sending request, it realizes more more flexible and complicated than using the band external information, and its resource cost still less, and therefore, sending data sending request by in-band information to base station in service sector with the non-service cell base station below is that example describes.

As previously mentioned, during by in-band information carrying data sending request, can expand the type of existing channel frame, also can utilize the unused word section in the existing channel frame, below its embodiment be illustrated respectively:

First kind of situation: the type of expansion existing channel frame is carried data sending request.

For example, receiving the correct non-service cell base station of data can expand dedicated transmission channel Frame Protocol (DCH FP) frame and carry data sending request.DCH FP frame is carried on the Iur interface between the Node B+, can carry the data sending request in this step, and the data in the step 404 send response by the control frame (Control Frame) among the existing DCH FP of expansion.

Only defined 00000001～00001011 this several types in the control frame type on the existing Iur interface, the control frame type of existing DCH FP and the mapping table of coding are as shown in table 1:

Table 1

The present invention can expand on the existing Iur interface type of control frame among the DCH FP, and other beyond the definite division 00000001～00001011 are encoded and represented information interaction in the embodiment of the invention.For example, be provided with 00001100, the expression data sending request, and will characterize the reception data correctness information be carried in this control frame.Usually, control frame can be according to structure construction as shown in table 2:

Table 2

Referring to table 2, for the frame type of embodiment of the invention expansion: data sending request can insert 00001100 in the control frame type field, and the information that will characterize the reception data correctness is carried in this control frame.For example, can in table, carry the information that receives data correctness that characterizes shown in " control information " in the field, perhaps carry the information that receives data correctness that characterizes in other fields that can be used for the information of carrying.Need to prove, the structure that table 2 just may have with a typical control frame is the building method of example explanation control frame of the present invention, be not to be used to limit control frame of the present invention can only adopt structure shown in Figure 2 to construct, the control frame of the embodiment of the invention can certainly adopt other modes to construct.

Second kind of situation: utilize the unused word section in the existing channel frame to carry data sending request.

The unused word section that receives in the uplink data frames that the correct non-service cell base station of data can utilize DCH FP is carried data sending request.Here, unused word section can be the reserved field in the frame or reserve extended field or other can be used to carry the field of data sending request information of the present invention.When the non-service cell base station adopts this mode to carry data sending request, can realize that uplink interaction information sends with upstream data, can the conserve bandwidth resource, improve efficiency of transmission.

Just based on the illustrating of the embodiment of the invention, any utilizable in-band information all can be used for the data sending request of this step to above-mentioned two kinds of situations.

Step 404: base station in service sector selects to carry out the non-service cell base station that data send according to received data sending request, and sends response to this non-service cell base station return data.

In this step, base station in service sector can be passed through in-band information, also can send data to the non-service cell base station by the band external information and send response.

Similar with step 403, the mode of carrying by the band external information can be the new signaling message of definition, for example, can be according to certain form, the new RNSAP signaling message of definition sends response as data on the Iur interface, does not repeat them here;

The mode of carrying by in-band information can be the type of the existing dedicated transmission channel frame of expansion, also can be the existing Common transport channel frame of expansion type, can also be to utilize unused word section in the existing channel frame to carry data to send response, the embodiment to these three kinds of situations is illustrated respectively below:

First kind of situation: the type of the existing dedicated transmission channel frame of expansion is carried data and is sent response.

Here, with reference to the method in the step 403, the present invention also can expand on the existing Iur interface type of control frame among the DCHFP, be provided with 00001101, the expression data send response, and send response according to the data in any this step of structure construction that can construct control frame of structure as shown in table 2 or other.

Second kind of situation: the type of the existing Common transport channel frame of expansion is carried data and is sent response.

Base station in service sector can receive the correct non-service cell base station of data to certain by the mode of expansion Common transport channel Frame Protocol (CCH FP) frame and send data transmission response.Only defined 00000010～00001011 this several types in the control frame type of existing CCH FP, the control frame type of existing CCH FP and the mapping table of value are as shown in table 3:

Control frame type (Type of control frame)	Value (Value)
		FACH?Flow?Control	00000010

FACH?Capacity?Request	00000011
		DSCH?Capacity?Request	00000100
DSCH?Capacity?Allocation	00000101
		HS-DSCH?Capacity?Request	00001010
HS-DSCH?Capacity?Allocation	00001011

Table 3

The present invention can expand the type of control frame among the existing CCH FP, and other beyond the definite division 00000010～00001011 are encoded and represented information interaction among the present invention.For example, be provided with 00001100, the expression data send response.After the expansion table registration is according to the control frame type that sends response, can according to step 403 in construction data send the similar mode construction data of request and send response, and Radio Network Temporary Identifier (RNTI) is carried on this data sends in the response, to distinguish different users.

The third situation: utilize the unused word section in the existing channel frame to carry data transmission response.

When base station in service sector exists downlink data need pass to the non-service cell base station, also can according to second kind of similar mode of situation described in the step 403, utilize unused word section in the downlink data frame of DCH FP to carry data and send response.Here, unused word section can be the reserved field in the frame or reserve extended field or other can be used to carry the field of data sending request information of the present invention.Carry data when sending response when base station in service sector adopts this mode, can realize that descending interactive information sends with downlink data, can the conserve bandwidth resource, improve efficiency of transmission.

Just based on the illustrating of the embodiment of the invention, the data that any utilizable in-band information all can be used for this step send response to above-mentioned three kinds of situations.

In this step, if base station in service sector receives only the data sending request that comes from a non-service cell base station, then directly this non-service cell base station is defined as carrying out the non-service cell base station that data send, sends response to this non-service cell base station return data;

If base station in service sector receives the data sending request that comes from a plurality of non-service cells base station, the pairing base station of request that then can select to receive at first is defined as carrying out the base station that data send, perhaps according to uplink signal-channel quality characteristic that is comprised in the data sending request or user performance information, from this a plurality of non-service cells base station, select a best conduct to carry out the base station that data send, perhaps select a conduct to carry out the non-service cell base station that data send arbitrarily, send response to this non-service cell base station return data.Here, select best non-service cell base station except can also selecting according to other modes according to uplink signal-channel quality characteristic or the user performance information etc. according to existing correlation technique.

Step 405: the non-service cell base station that receives data transmission response sends to base station in service sector with the reception data on its corresponding Radio Link.

In this step, the data that the non-service cell base station is returned according to base station in service sector send response, judge it himself is to be determined to carry out the non-service cell base station that data send, so the data that the reception on the corresponding Radio Link is correct send to base station in service sector.

Step 406: base station in service sector will come from the data of non-service cell base station as correct data, participate in uplink macro diversity and merge.

In this step, base station in service sector receives after the data that come from the non-service cell base station, can according to the similar mode of step 402, should receive data and be defined as correct data, according to existing grand diversity folding these data are handled then, and the data after will handling are uploaded to core net by the Iu interface.

So far, finish the flow process of ascending macro diversity combining method of the present invention.

As seen from the above-described embodiment, in the disclosed ascending macro diversity combining method of present embodiment, when base station in service sector judges that its data that receive are correct, directly these data being participated in uplink macro diversity as correct data merges, and taked not respond the mode of the data sending request of non-service cell base station, avoid the non-service cell base station to send data to base station in service sector again, so, can greatly reduce the redundant transmission amount of uplink macro diversity between the base station, and, because need not wait for the correct data of reception that the non-service cell base station sends, user plane time delay is also reduced;

And when base station in service sector judges that its data that receive are incorrect, then according to the data sending request that comes from the non-service cell base station, therefrom select one, and to its corresponding non-service cell base station response data transmission response, to notify this non-service cell base station to send data to base station in service sector or core net, so, make the redundant transmission amount of uplink macro diversity between the base station obtain better controlled, and, because it is considerably less to carry out the needed data volume of the described information interaction of the embodiment of the invention, make user plane time delay also obtain control preferably.

And the data sending request of present embodiment and data send response can be carried on in-band information, also can be carried on the band external information.For the mode that is carried on in-band information, can on the basis of redundant transmission amount between the control base station, further save the transfer resource between the base station.

Embodiment two:

In the present embodiment, the non-service cell base station will initiatively send to base station in service sector and receive correct data under the default situations, for this reason, in the non-service cell base station, be provided with the short timer of timing, when and expression that this timer expiry after as yet do not receive base station in service sector correct when the reception data of certain non-service cell base station do not send the instruction of data, this non-service cell base station will initiatively send the correct data of reception to base station in service sector.

Fig. 5 is the schematic flow sheet of ascending macro diversity combining method in the embodiment of the invention two.Referring to Fig. 5, this method may further comprise the steps:

Step 501: base station in service sector judges whether the data that himself receive are correct, if correct, continues execution in step 502; Otherwise, continue execution in step 503.

In this step, base station in service sector can be checked the correctness that receives data on himself Radio Link according to prior art, when assay is correct for receiving, continues execution in step 502; Otherwise, continue execution in step 503.

Step 502: base station in service sector selects reception data on the Radio Link of himself correspondence as correct data, participates in uplink macro diversity and merges, and send the instruction that expression does not send data to all non-service cell base stations, finishes the present embodiment method flow.

In addition, because in the present embodiment, the non-service cell base station will initiatively send to base station in service sector and receive correct data under the default situations, therefore, in this step, base station in service sector should send the instruction that expression does not send data to all non-service cell base stations, sends unnecessary redundant data to avoid the non-service cell base station to base station in service sector.

Base station in service sector can send the instruction that expression does not send data to all non-service cell base stations by in-band information or band external information in this step.

Similar with embodiment one, the situation for carrying by the band external information can define new signaling message, for example, can be according to certain form, the new RNSAP signaling message of definition sends response as data on the Iur interface, does not repeat them here;

For the situation of carrying by in-band information, can send the similar mode of response according to data sending request and data among the embodiment one and construct the instruction that expression in the present embodiment does not send data, both can expand the type of existing dedicated transmission channel frame, also can expand existing Common transport channel frame type, can also utilize unused word section in the existing channel frame to carry the instruction that expression in this step does not send data.

For example, can expand on the existing Iur interface type of control frame among the DCH FP, beyond the definite division 00000001～00001011 other are encoded and are represented not send data command in this step, and can construct the instruction that expression in this step of structure construction of control frame does not send data according to structure as shown in table 2 or any other;

Also can expand the type of control frame among the existing CCH FP, beyond the definite division 00000010～00001011 other are encoded and are represented not send data command in this step, can construct the instruction that expression in this step of structure construction of control frame does not send data according to structure as shown in table 2 or any other then, and RNTI is carried in this instruction, to distinguish different users;

In addition, can also utilize the unused word section in the downlink data frame of DCH FP to carry the instruction that expression does not send data.

Step 503: receive the timer expiry in the correct non-service cell base station of data, and do not receive come from base station in service sector do not send instruction, then send the correct data of reception on its corresponding Radio Link to base station in service sector.

Because base station in service sector himself is receiving data when incorrect, the instruction of data will do not sent to the non-service cell base station, therefore, in this step, when the process check of non-service cell base station, the data that Radio Link received of determining this sub-district are correct, and behind timer expiry, also do not receive the instruction that the expression that comes from base station in service sector does not send data, then the non-service cell base station judges that the data of base station in service sector reception are incorrect, should send to base station in service sector with receiving correct data on the Radio Link of himself correspondence, so, the correct data of reception on its corresponding Radio Link are sent to base station in service sector.

Step 504: base station in service sector is selected one as correct data from the data that receive, and participates in uplink macro diversity and merges.

In this step,, then directly these data are defined as correct data if base station in service sector receives only the data that come from a non-service cell base station; If base station in service sector receives the data that come from a plurality of non-service cells base station, then can therefrom select one and be defined as correct data, specifically can be that the data that selection receives are at first perhaps selected at random.Then according to the similar mode of step 502, with reference to existing grand diversity folding these data are handled, and will be handled data afterwards and upload to core net by the Iu interface.

So far, finish ascending macro diversity combining method flow process of the present invention.

As seen from the above-described embodiment, in the disclosed ascending macro diversity combining method of present embodiment, when base station in service sector judges that its data that receive are correct, directly these data being participated in uplink macro diversity as correct data merges, and taked to send the mode that expression does not send the instruction of data to the non-service cell base station, avoid the non-service cell base station to send data to base station in service sector again, so, can greatly reduce the redundant transmission amount of uplink macro diversity between the base station, and, because need not wait for the correct data of reception that the non-service cell base station sends, user plane time delay is also reduced;

And when base station in service sector judges that its data that receive are incorrect, do not send any instruction to non-service cell, receive the correct non-service cell base station of data with notice and send data to base station in service sector, so, make the redundant transmission amount of uplink macro diversity between the base station obtain better controlled, and the needed data volume of the described information interaction of the embodiment of the invention is considerably less owing to carrying out, and makes user plane time delay also obtain control preferably.

And the instruction that the expression of present embodiment does not send data can be carried on in-band information, also can be carried on the band external information.For the mode that is carried on in-band information, can on the basis of redundant transmission amount between the control base station, further save the transfer resource between the base station.

Among above-mentioned two embodiment, receive the correct non-service cell base station of data and judge himself to be to be determined after the base station of carrying out the data transmission, all that it is received data send to base station in service sector, by base station in service sector data are carried out sending to core net after the grand diversity merging.In actual applications, be determined and carry out the data that non-service cell base station that data send also can be received with it and directly send to core net, carry out grand diversity and merge receiving correct data by core net.Directly send the data in the non-service cell base station under the situation of core net, in the UE Active Set each is jumped link all to be needed to set up a GPRS tunnel passage (GTP) on the Iu interface for this communication of this UE, simultaneously, core net need be safeguarded the correspondence relationship information of this UE and many GTP passages, and the non-service cell base station can be connected with Iu interface between the core net by this base station and directly this base station received correct data and send to core net.For embodiment in this case, can carry out with reference to embodiment one and embodiment two, do not repeat them here.
