Description
Technical field
The present invention relates to the communications field, in particular to a kind of based on striding data processing method, changing method, device and the system that HSGW (HRPD gateway, HRPD Serving Gateway) switches.
Background technology
3GPP (third generation partner program, 3rd Generation Partnership Project) SAE (system architecture of evolution, System Architecture Evolved) by E-UTRAN (the universal mobile telecommunications system land radio access web of evolution, Evolved UniversalTerrestrial Radio Access Network), MME (mobile management unit, MobilityManagement Entity), S-GW (gateway, Serving Gateway), P-GW (grouped data network gateway, Packet Data Network Gateway), HSS (home subscriber server, Home Subscriber Server), 3GPP aaa server (3GPP authentication and authorization charging server), and other support nodes are formed.Wherein, E-UTRAN is the Access Network of SAE system; MME is responsible for the chain of command related work; S-GW is the accessing gateway equipment that links to each other with E-UTRAN; P-GW is the 3GPP EPS (grouping system of evolution, EvolvedPacket System) with PDN (Packet Data Network, Packet Data Network) borde gateway, be responsible for PDN access, between EPS and PDN, transmit data, P-GW still is a terminal at user's face anchor point that 3GPP inserts and non-3GPP switches between inserting.3GPP2 (third generation partner program 2,3rd Generation Partnership Project 2) grouping system (CDMA2000 1X EV-DO, CDMA2000 1X Evolution-Data Only) is called HRPD (HRPD (high rate packet data) again, High Rate Packet Data), by HRPD-AN (HRPD Access Network, HRPD Access Network), PDSN (packet data serving node, Packet Data Serving Node), HA (home agent, Home Agent), 3GPPAAA server (3GPP2 authentication and authorization charging server) and other support nodes are formed.PDSN is the accessing gateway equipment that links to each other with HRPD-AN, is responsible for user's mobile management, context management, transmits data between HRPD-AN and HA, and is responsible for pending datas such as paging are carried out buffer memory; HRPD-AN and HA are respectively Access Network and home agent.
The intercommunication of SAE network support and HRPD network (Interworking), Fig. 1 is the Organization Chart according to the HRPD-SAE intercommunication of correlation technique, as shown in Figure 1, in the intercommunication framework, for unified with the SAE network element, rename as HSGW behind the PDSN function upgrading, HRPD-AN is called the HRPD-eAN (Access Network of evolution behind function upgrading, evolvedAccess Network), the interface between HRPD-eAN and the HSGW is A10 '/A11 ' interface by original A10/A11 interface upgrade.In the intercommunication scene, data anchor point is P-GW, and transfer of data must be passed through 3GPP data gateway P-GW.In order to realize that multimode terminal inserts by different access technologies, newly-increased network element interface has: S101 interface, S103 interface and S2a interface.The S2a interface transmits control and bearer service between HSGW and P-GW, adopt the PMIPv6 agreement.
UE is by the HRPD network insertion, when the HRPD network internal is striden the HSGW switching, P-GW is as mobile anchor point, Fig. 2 is the schematic diagram of striding the HSGW switching according to the UE of correlation technique, as shown in Figure 2, S-eAN and S-HSGW are respectively source Access Network (Source eAN) and the source access gateways (Source HSGW) before switching, and T-eAN and T-HSGW are respectively target access network (Target eAN) and target access gateway (Target HSGW).Before the switching, pass through the data channel intercommunication data of S2a interface between P-GW and the S-HSGW.When the switching of striding HSGW is initiated, by chain of command interface Hx_C forwarding contexts information, simultaneously, set up the data channel of data surface interface Hx_U between S-HSGW and the T-HSGW, be used to transmit data.
Striding HSGW switching core net flow process is finished by following three parts: Hx_C interface context transfer, the Hx_U data channel is set up, S2a interface proxy mobility binding.Wherein, in Hx_C interface context transfer, the Hx_U data channel is set up thereupon, and then carries out the PMIP binding between P-GW and the T-HSGW, and data channel is by the tangential T-HSGW of S-HSGW.
Fig. 3 strides the flow chart that HSGW switches according to UE under the state of activation of correlation technique, as shown in Figure 3, comprises the steps:
Step S301, UE inserts the SAE network by S-eAN, S-HSGW, and by P-GW and outside PDN intercommunication data;
Step S302, UE are initiated to switch and notice UE by the S-eAN decision to the report of S-eAN pilot signal transmitted intensity;
Step S303, S-eAN sends " request of A16 session transmissions " signaling and gives T-eAN, and wherein, " request of A16 session transmissions " signaling carries the HRPD session information of the current UE that will switch; Receive at T-eAN after " request of A16 session transmissions " signaling, send " response of A16 session transmissions " signaling to S-eAN;
Step S304, after S-eAN receives " response of A16 session transmissions " signaling of T-eAN transmission, send " the A16 session transmissions is finished " signaling to T-eAN again, if the HRPD session information changes to some extent after step S303, will in this signaling, bring T-eAN the HRPD session information that upgrades;
Step S305, T-eAN sends " A11 ' register requirement " signaling to T-HSGW, set up T-eAN by this signaling and is connected with A10 ' between the T-HSGW, and notice T-HSGW initiates the forwarding data channel and sets up flow process;
Step S306, T-HSGW and S-HSGW intercommunication " handoff request with reply " signaling, parameters such as transmission session context, signatory context, GRE Key simultaneously, are set up the data surface passage between S-HSGW and the T-HSGW;
Step S307, T-HSGW sends " A11 ' registration respond " signaling to T-eAN, and A10 ' connects and sets up successfully;
Step S308, data channel is set up successfully between S-HSGW and the T-HSGW, and T-HSGW sends " switching is finished " signaling to S-HSGW;
Step S309, after step S308 finished, downlink data can issue by path " P-GW → S-HSGW → T-HSGW → T-eAN ", and at the T-eAN buffer memory;
Step S310, S-eAN sends " traffic channel assignments " signaling to UE, and notice UE this moment can be with wireless channel by the tangential T-eAN of S-eAN, and this step is triggered by step S303, can carry out in any time after the step S303;
Step S311, UE is linked into T-eAN, and wireless channel is set up successfully, then, begins to be handed down to UE at the downlink data of T-eAN buffer memory;
Step S312, A10 ' connect to set up upgrade, T-HSGW and P-GW binding, after this step is finished, on/downlink data can pass through the path " UE ← → T-eAN ← → T-HSGW ← → P-GW " transmit;
Step S313, system resource discharges, and comprising: the HRPD session information of S-eAN, S-eAN be connected with A10 ' between the S-HSGW and S-HSGW and T-HSGW between user's face passage.
By analysis to above flow process, as can be seen: in original HRPD network, " traffic channel assignments " (promptly, step S310 among Fig. 3) be that signaling (promptly by " response of A16 session transmissions ", step S303 among Fig. 3) triggers, and, after " traffic channel assignments " step is carried out, trigger UE thereupon and switch wireless channel (that is step S311 among Fig. 3), therefore, wireless channel switches actual capabilities and occurs in data forwarding passage foundation (that is, step S305-step S308 among Fig. 3) before, at this moment, data forwarding passage between S-HSGW and the T-HSGW is not also built up, therefore downlink data can only be issued to S-eAN by S-HSGW, because this moment, wireless channel switched, UE has switched under the T-eAN, therefore the data that are transferred to S-eAN can not be transferred to UE again, and then cause the phenomenon of lost data packets.
