Background technology
Mobile radio network brings the convenience that people enjoy information and interconnection services whenever and wherever possible。UMTS (UniversalMobileTelecommunicationSystems, UMTS) it is the 3-G (Generation Three mobile communication system) adopting WCDMA (WidebandCodeDivisionMultipleAccess, WCDMA accesses) air interface technologies。Therefore UMTS system is also commonly called WCDMA system。WCDMA system is made up of following network element: UE (UserEquipment, subscriber terminal equipment), UTRAN (UMTSTerrestrialRadioAccessNetworkUMTS, grounding wireless access network) and CN (CoreNetwork, core net)。Wherein UTRAN completes the correlation function that wireless side processes, and CN is responsible for carrying out voice-and-data exchange with external network。
When UE is in handoff state, to communicate with the base station (Nodeb) of multiple participation handovers simultaneously, signal from these base stations is merged process, improve uplink and downlink signal quality, ensure that in handoff procedure, data are not lost, making UE communication in moving process unaffected, this technology is exactly macro-diversity。Under macro diversity status, UE is by merging the TPC (TransmitPowerControl that different base station (NodeB) issues, uplink power control) order, adjust uplink transmission power, ensure, under meeting the premise that after upstream data merges, data are correct, to reduce uplink transmission power as far as possible。Under the premise of this treatment mechanism, there is two or a multilink only upstream data BLER (BlockErrorRatio of macro-diversity in very big probability, bLock error rate) meet performance requirement, although same packet being sent to other up-links for mistake bag, but reach the purpose of wireless system choosing comprehensively wireless quality and power system capacity。UE sends upstream data, by Iub (InterfaceUnionBaseStation after NodeB eats dishes without rice or wine demodulation, the connection interface of base station controller and base station) transmission is sent to RNC (RadioNetworkControl, radio network controller), the two or more base station of same bag data approach respectively that under macro diversity situation, UE sends is uploaded to RNC, RNC is responsible for determining the switching of UE, and completes data merging。It is that in prior art, RNC-NodeB node synchronizes schematic diagram with reference to Fig. 1, Fig. 1；As it is shown in figure 1, RNC obtains propagation delay time by node synchronization frame。Transmit path distance due to the Iub of different websites and business load situation will not be identical, so each link data arrival RNC exists delay inequality under macro diversity status。For the delay variation overcoming data to transmit, RNC is provided with regular time window, RNC is incorporated in set time window scope time difference each link data arrived, according to certain standard such as bit error rate, each link data is compared, when having at least a link data bag to satisfy condition, the packet that this is correct is transferred to CN。
Fast development along with mobile network, Iub transmission network is day by day complicated, such as ATM (AsynchronousTransferMode, asynchronous transfer mode), FE (FastEthernet, Fast Ethernet) and multistage transmission node mode, there is propagation delay time difference in different transmission means, also likely to be present the propagation delay time shake that uncertain factor introduces in network。In prior art, when macro diversity status carries out data merging, adopt the mode that set time window is set, but this traditional approach is difficult to overcome the change of divergence of Suresh Kumar networking mode transmission time delay difference；Therefore, can there is problems in that if only vicious packet reaches RNC before timer expiry under macro diversity situation, same CFN (ConnectionFrameNumber after timer expiry, continuous frame number) correct packet just arrive, so can cause RNC that in the moment reaching set time window, the packet of mistake is sent to CN, and correct packet can be dropped because of too late arrival, cannot participating in merging, thus producing unnecessary wrong bag thus affecting quality of service。
