Description
Technical field
The present invention relates to the communications field, particularly relate to a kind of method for switching network and network system。
Background technology
In recent years, along with fast development and the people of mobile communication technology are more and more higher to the requirement of high-speed data service, HRPD (HighRatePacketData, referred to as HRPD) network is in continuous evolution。In order to realize and strengthen universal land radio access web (EnhancedUniversalTerrestrialRadioAccessNetwork, referred to as E-UTRAN) interoperability, HRPD is evolved to evolution high-speed packet data network (EvolvedHighRatePacketData, referred to as eHRPD)。
Fig. 1 is interoperability configuration diagram between eHRPD and E-UTRAN, as shown in Figure 1, wherein, eHRPD network is made up of following network element: the Access Network (EvolvedAccessNetwork of evolution, referred to as eAN), the Packet Control Function (EvolvedPacketControlFunction of evolution, referred to as ePCF), high-speed packet data service gateway (HRPDServingGateway, referred to as HSGW) etc.；Wherein, E-UTRAN network is made up of following network element: Mobility Management Entity (MobilityManagementEntity, referred to as MME), packet data network gateway (PacketDataNetworkGateway, referred to as PGW), gateway (ServingGateway, referred to as SGW), E-TURAN base station etc.。
EHRPD is wireless to original HRPD, packet core network has carried out function enhancing。EHRPD also brings a series of new features, as many PDN supports, load multiplexing, network side initiate QoS, MUPSAP (MultiplePDNConnectionstoASingleAPN, many PDN (public data network) are connected to an APN (access point)) etc.。
In eHRPD network, MUPSAP function allows subscriber equipment (UserEquipment, referred to as UE) to set up multiple PDN and be connected to an APN, each PDN connection PDN-ID (PDNIdentifier)+UserContextIdentifier (user's context mark) uniquely identifies；But under current several network elements, P-GW knows APN, it is not aware that user's context identifies, MME also only knows APN, P-GW address, GREKey (GenericRoutingEncapsulationKey, generic route encapsulation keyword), it is not aware that user's context identification information, and HSGW is after S101 tunnel sends data, only know APN, P-GW address, GREKey, but cannot determine that uplink message is corresponding with which GREKey for MUPSAP scene, it is impossible to forward uplink message in time。Cause that uplink message interrupts。
In current techniques, optimize switching flow as shown in Figure 2 under user's state of activation, comprise the following steps:
1a, UE (terminal) determine to be switched to eHRPD。
1b, UE send HRPDConnectionRequest (HRPD connection request) to MME (mobile management entity)。
1c, MME send APN, P-GW address, GREKey information to eHRPD by S101 tunnel。
2a, eHRPDeAN/ePCF send A11 registration request (RRQ) to HSGW, wherein comprise APN, P-GW address, the GREKey information etc. that receive from S101 tunnel。
2b, HSGW return A11 registration response (RRP) to eAN/ePCF, wherein comprise the APN information etc. of S103 tunnel address, GREKey, association。
3, eHRPDeAN/ePCF by S101 tunnel to MME echo should。
4a, MME notify that SGW creates S103 tunnel。
4b, MME send HRPDTCA message informing UE。
5, SGW sends downlink data by S103 tunnel。
6a, UE obtain eHRPDradio (UE is switched under eHRPD environment)。
6b, UE send TCC message to eHRPDeAN/ePCF。
7a, eHRPDeAN/ePCF send the instruction of A11-RRQ message to HSGW and activate and switching。
7b, HSGW return A11-RRP response to eHRPDeAN/ePCF。
8a, connecting for each PDN, HSGW sends PBU to P-GW and sets up PMIPv6 tunnel。
8b, P-GW return PBA response, with identical IP address, confirm that tunnel is successful。
8c is if it is required, P-GW and hPCRF interactive refreshing IP-CAN information。
8d, eHRPDeAN/ePCF pass through S101 tunnel, notify MME handover success。
9, UE accesses network by eHRPD。
10, E-UTRAN discharges related resource。
It can be seen that descending data just can utilize S103 tunnel to send in the 5th step from said process, it is not result in middle-end, but up data, it is necessary to could send after waiting until the 9th step, cause that upstream data interrupts。Because before this, for MUPSAP scene, utilize APN can find the GREKey of multiple P-GW, it is impossible to distinguish which use。
