Description
Technical field
The present invention relates to field of mobile communication, particularly relate to the transmission method of a kind of code division multiple access (Code Division Multiple Access, referred to as CDMA) base station system and message thereof.
Background technology
At present, commercial cdma base station system (such as, CDMA2000 base station system) supports CDMA 1x and EVDO two kinds of data services simultaneously, and a lot of community has 1x to cover simultaneously, also has DO to cover.So generally speaking cdma base station system, is 1x Access Network, agreement is called base station (Base Station, be called for short BS, hereinafter referred to as 1x BS), be again EVDO Access Network, agreement is called access network (Access Network is called for short AN, hereinafter referred to as DOAN).
Fig. 1 is the connection diagram of network element in the cdma system according to correlation technique, as shown in Figure 1, describe according in 3GPP2 protocol specification A.S0008 (AN realizes Session controlling functions), Packet Control Function (Packet Control Function, be called for short PCF), 1xBS can be connected separately, or connect DOAN separately, also can connect 1xBS and DOAN simultaneously.
Inside CDMA 1x agreement, user is called as travelling carriage (Mobile Station is called for short MS), inside EVDO agreement, user is called as and accesses terminal (Access Terminal is called for short AT), unify below use access terminal (i.e. AT) describe.
For making to access terminal smoothly movement between different base station, and it is continuous to maintain data service, so handover configurations must be carried out between dissimilar CDMA base station system, and for user selects same group data service node (PacketData Service Node is called for short PDSN) between guarantee different base station.
For EVDO, switched by interfaces such as A13, A16, A17 between different AN.Wherein, A13 is that dormancy switches (Dormant Handoff), and A16 switches (Active Handoff) for activating.Fig. 2 is the schematic diagram carrying out switching between dissimilar CDMA base station system that accesses terminal according to correlation technique, as shown in Figure 2, how should process when data service change is occurred between 1x BS and DO AN under same PCF for a terminal use, correspondingly not describe in existing agreement.But inventor finds, in this case, because source DOAN cannot preserve correct PDSN address, so when user can be caused to be switched to target side AN (that is, 1x BS), the PDSN address that A13 and A16 interface transmits produces mistake.Concrete scene is as follows:
1) user is after source DO AN carries out data service foundation, then discharges.Because of certain reason (such as, community DO dropout), user accesses at source 1x BS and carries out data service, and PCF can select a PDSN to set up data service according to the principle of load sharing.Now, the PDSN address of preserving in source DO AN may not be the PDSN address that user is now just accessing under 1x BS.So under user is switched to target side DOAN, the PDSN address got by A13 and A16 may be wrong, can cause data traffic interruptions like this.
2) user is after source DO AN carries out data service foundation, carries out data service, then release because certain reason (such as, cell portion DO dropout) can be switched to source 1x BS.Now, in the session information of source DO AN, this PDSN address should be set invalid.So, user be switched to again call out under the DO AN of target side time, the PDSN address got by A13 is wrong, and target side PCF can be caused like this cannot to be that user reselects a suitable PDSN according to the principle of load sharing.
Summary of the invention
