Femto cell is connected with relevant device by IP network, and femto cell inside comprises physics (PHY) layer, media access control (MAC) layer, wireless link control (RLC) layer and Radio Resource control (RRC) layer.As shown in Figure 1, terminal connects one or more femto cell, and multiple femto cell are connected to gateway by IP network, and gateway is connected to core net by IP network again.In general, a gateway can connect up to ten thousand femto cell by IP network.
In broadband CDMA system, communicating by letter between terminal and wireless network, has applied soft hand-off.So-called soft handover refers in the time that terminal starts with new base station communication, does not interrupt immediately communicating by letter between former base station.In the process of soft handover, terminal may communicate with two or more base stations simultaneously, from a base station is switched to the process of another base station, does not need to change transmitting-receiving frequency, there is no the phenomenon of the temporary transient interruption of communication.
In the time that soft handover occurs, on the up direction of transfer of data, the signal that terminal sends is received by different femto cell, and each femto cell can send to gateway by the identical data receiving respectively.The measured value of the measurement communication quality that gateway reports according to each femto cell, judges the transmission quality optimum of which bar communication channel, and the Packet Generation that the femto cell that this communication channel is connected receives is to core net.Therefore, in the prior art, the data of up-link wireless link transmission complete selectivity and merge in gateway, obtain receive diversity gain, are called grand diversity technique.Several base stations that can receive some terminal same signals, are called Active Set.But, gateway connects up to ten thousand femto cell, wherein use the Active Set of grand diversity may have a lot, each Active Set has at least comprised two femto cell, in the time that the femto cell of the grand diversity of all uses is reported to gateway by its packet with corresponding measurement of communication quality value, gateway needs a large amount of packet of buffer memory, and this may realize in practice hardly.
At present, multiple femto cell in the Active Set of the grand diversity of each use are only reported to gateway by measurement of communication quality value corresponding packet, gateway judges the quality good or not of the packet receiving from base station according to the measurement of communication quality value of the packet receiving from different base station, issue again each femto cell that signaling is corresponding, the top-quality femto cell reported data bag that makes the packet receiving, other femto cell in this Active Set is abandoned packet.But, because gateway needs its corresponding measurement of communication quality value of comparison to each packet, therefore, each packet can increase a round-trip delay in user plane time delay, for the larger IP return network of time delay, this will make communication quality make especially speech service quality decline to a great extent.
In sum, the existing gateway connected with using femto cell in the Active Set of grand diversity is owing to each packet being needed to its corresponding measurement of communication quality value of comparison, and then to signaling under the base station in Active Set, upload or packet discard indication base station, this can produce larger time delay, thus cause communication quality particularly speech service quality decline to a great extent.

Embodiment
A kind of method and device of realizing uplink macro diversity that the embodiment of the present invention provides, according to the channel quality value receiving in current slot between that each base station in the Active Set that subscriber equipment is corresponding reports and this subscriber equipment, determine the base station that needs reported data in each base station by gateway device; And indicate the base station of determining, within next time period, the data from this subscriber equipment that receive are sent to this gateway device, thus reduce time delay, overcome the communication quality problem that particularly speech service quality declines to a great extent.
Below in conjunction with Figure of description, what the embodiment of the present invention was provided a kind ofly realizes the method for uplink macro diversity and the embodiment of device describes.
A kind of method that realizes uplink macro diversity that the embodiment of the present invention provides, as shown in Figure 2, specifically comprises the following steps:
Channel quality value between that S201, gateway device report according to the each base station in Active Set corresponding to the subscriber equipment receiving in current slot and this subscriber equipment, determines the base station that needs reported data in each base station;
S202, gateway device indicate the base station of determining, within next time period, the data from this subscriber equipment that receive are sent to this gateway device.
Wherein, the length of current slot and next time period can equate, that is to say, gateway device is periodically determined the base station that needs reported data in the each base station in the Active Set that subscriber equipment is corresponding.
Suppose in application scenarios one, in Active Set corresponding to subscriber equipment A, comprise three base stations, be respectively base station 1, base station 2 and base station 3, gateway device is according to the channel quality value between the base station 1 receiving in time period T1 and subscriber equipment A, channel quality value between channel quality value and base station 3 and subscriber equipment between base station 2 and subscriber equipment A, determine the base station 1 in the Active Set that in the time period T2 after time period T1, subscriber equipment A is corresponding, in base station 2 and base station 3, need to the base station of gateway device reported data, and the base station that indication is determined sends to gateway device by the data from subscriber equipment A that receive in time period T2.
In embodiments of the present invention, when subscriber equipment sends packet in the base station in Active Set, when not needing a packet of every reception, this base station just goes to detect once the channel quality value between this subscriber equipment and this base station, that is to say, might not there is relation one to one in the packet that the channel quality value between this base station and this subscriber equipment that this base station reports to gateway device and this base station receive from this subscriber equipment.For example, in current slot, this base station reports once the channel quality value between this base station and this subscriber equipment, and this base station receives multiple packets from this subscriber equipment.
Further, gateway device can receive the channel quality value between that base station in this Active Set reports and this subscriber equipment each time in next time period after current slot after, the data from this subscriber equipment that receive are sent to this gateway device by the base station that indication is determined.
For example, in application scenarios one, after gateway device receives each time the channel quality value between that any one base station in base station 1, base station 2 and base station 3 reports and subscriber equipment A in time period T2, the data from subscriber equipment A that receive are sent to gateway device by the base station that indication is determined in time period T1.
Preferably, gateway device can be after current slot finishes, and the base station that indication is determined immediately sends to this gateway device by the data from this subscriber equipment that receive within next time period; Also, after can receiving for the first time the channel quality value between that base station in this Active Set reports and this subscriber equipment in next time period after current slot, the base station that indication is determined sends to this gateway device by the data from this subscriber equipment that receive within next time period.
For example, in application scenarios one, gateway device, after the time period, T1 finished, indicates the base station of determining in time period T1 that the data from subscriber equipment A that receive in time period T2 are sent to gateway device immediately; Or receive for the first time the channel quality value between any base station and the subscriber equipment A in base station 1, base station 2 and base station 3 in time period T2 time, the data from subscriber equipment A that receive in time period T2 are sent to gateway device by the base station that indication is determined in time period T1.
In this case, gateway device only needs indication once in time period T2, further reduce the Signalling exchange between gateway device and base station, thereby further reduced the round time delay of bringing due to Signalling exchange, reduced the time delay in communication process.
Further, the channel quality value that gateway device reports according to the each base station in Active Set corresponding to the subscriber equipment receiving in current slot is determined the base station that needs reported data in each base station, comprising: gateway device is determined respectively the mean value of the channel quality value between that the each base station in this Active Set receiving in current slot reports and this subscriber equipment; Gateway device is according to the mean value of definite channel quality value, using base station best channel quality in described Active Set as the base station that needs reported data.
For example, in application scenarios one, suppose that gateway device receives the channel quality value Q1 between that report and the subscriber equipment A in base station 1 in time period T1, and receive channel quality value Q2 and the Q3 between that report and the subscriber equipment A in base station 2, and receive channel quality value Q4, Q5 and Q6 between that report and the subscriber equipment A in base station 3; Gateway device determines that the mean value of the channel quality value between base station 1 and subscriber equipment A within the T1 time period is Q1, the mean value of the channel quality value between base station 2 and subscriber equipment A is (Q2+Q3)/2, and the mean value of the channel quality value between base station 3 and subscriber equipment A is (Q4+Q5+Q6)/3; Cyclic redundancy check (CRC) (the CRC of the packet transmitting between channel quality value is with base station and subscriber equipment A, Cyclic Redundancy Check) check errors number of times sum while representing, check errors number of times sum is less shows that the channel quality between base station and subscriber equipment is better, now, the base station of gateway device channel quality averaged minimum in base station 1, base station 2 and base station 3 and between subscriber equipment A within the T1 time period is as the base station that needs reported data; In the time that channel quality value utilizes the signal to noise ratio of communicating by letter between base station and subscriber equipment A to represent, the signal to noise ratio of communication shows that more greatly the channel quality between base station and subscriber equipment is better, now, the base station of gateway device channel quality averaged maximum in base station 1, base station 2 and base station 3 and between subscriber equipment A within the T1 time period is as the base station that needs reported data.
Further, gateway device does not receive the channel quality value between that base station in the Active Set that subscriber equipment is corresponding reports and this subscriber equipment in current slot, using the default base station in described Active Set as the base station that needs reported data.
For example, in application scenarios one, what in the time that the time period, T1 started, subscriber equipment A was corresponding comprises base station 1, the Active Set of base station 2 and base station 3 forms, now, due to before time period T1, what subscriber equipment A was corresponding comprises base station 1, the Active Set of base station 2 and base station 3 does not form, therefore gateway device was not received the channel quality value between that report and the subscriber equipment A in base station 1 before time period T1, channel quality value between that report and the subscriber equipment A in base station 2 and base station 3 is that report and subscriber equipment A between channel quality value, therefore, gateway device cannot be determined base station 1, in base station 2 and base station 3 in time period T1 the base station of reported data.Now, gateway device can be using the default base station in the base station in Active Set corresponding subscriber equipment A 1, base station 2 and base station 3 as the base station that needs reported data.
Further, the default base station in Active Set is that in the base station in this Active Set, first and gateway device are set up the best base station of channel quality in the base station in base station or the described Active Set of wireless link and between gateway device.
For example, in application scenarios one, default base station in base station 1, base station 2 and base station 3 in Active Set corresponding to subscriber equipment A can be the base station that in base station 1, base station 2 and base station 3, first and gateway device are set up wireless link, also can be after wireless link is all set up with gateway device in base station 1, base station 2 and base station 3, and the best base station of channel quality between gateway device.
Further, after gateway device needs the base station of reported data in each base station of determining in the Active Set that subscriber equipment is corresponding, indicate the data packet discarding that in this Active Set, other base station except the base station of determining sends the described terminal receiving in next time period.
After the indicating mode of the data packet discarding that other base station in this Active Set of this indication except the base station of determining sends the described terminal receiving in next time period can adopt the channel quality value between that the base station that receives each time in next time period in this Active Set reports and this subscriber equipment, indicate in this Active Set other base station except the base station of determining by the data packet discarding of the described terminal transmission receiving in next time period; Also can adopt after current slot finishes, indicate immediately the data packet discarding that in this Active Set, other base station except the base station of determining sends the described terminal receiving in next time period; After can also adopting the channel quality value between that the base station that receives for the first time in next time period after current slot in this Active Set reports and this subscriber equipment, indicate the data packet discarding that in this Active Set, other base station except the base station of determining sends the described terminal receiving in next time period.That is to say, indicate the data packet discarding that in this Active Set, other base station except the base station of determining sends the described terminal receiving in next time period within next time period, to send to this gateway device can adopt identical indicating mode the data from this subscriber equipment that receive with the base station of determining in this Active Set of indication.
