Description
Technical field
The present invention relates to the communications field, espespecially a kind of method and apparatus realizing stream migration.
Background technology
Increasingly mature and universal along with WLAN (wireless local area network) (WLAN, WirelessLocalAreaNetworks) access technology, and user is to the high-speed requirement of wireless access, domestic and overseas operators is all greatly developing WLAN business.At third generation partner program (3GPP, 3rdGenerationPartnershipProject) under framework, WLAN can be used as the packet-based core networks (EPC that non-3 gpp (non-3GPP) access network is connected to evolution, EvolvedPacketCore), as the supplementary access way of 3GPP network, in shunting, play more and more important effect.Fig. 1 is the composition schematic diagram of 3GPP framework.As shown in Figure 1,3GPP framework comprises grouping system (EPS, EvolvedPacketSystem) and the non-3GPP network of 3GPP evolution.Wherein, EPS comprises 3GPP access network and EPC, 3GPP access network comprises the universal mobile telecommunications system land radio access web (E-UTRAN of evolution, and mobile management unit (MME EvolvedUniversalTerrestrialRadioAccessNetwork), MobilityManagementEntity), EPC comprises gateway (S-GW, ServingGateway), grouped data network gateway (P-GW or PDNGW, PacketDataNetworkGateway), home subscriber server (HSS, HomeSubscriberServer), "Policy and Charging Rules Function (PCRF, PolicyandChargingRulesFunction) entity and other support nodes.Non-3GPP network comprises trust/non-trusted non-3GPP access network, and trust/non-trusted non-3GPP access network can be WLAN.Wherein, when non-3GPP access network is for trusting non-3GPP access network, UE is directly linked into EPC by P-GW; When non-3GPP access network is non-trusted non-3GPP access network, UE must be linked into EPC by the packet data gateway (ePDG, EvolvedPacketDataNetworkGateway) of evolution.
Internet protocol (IP, InternetProtocol) stream migration (IFOM, IPFlowMobility) technology can realize IP service flow and moves between different access networks, subscriber equipment can be modified to the routing rule of Business Stream when network congestion, thus raising communication quality, improve Consumer's Experience.Fig. 2 is the schematic diagram of Business Stream access EPC before migration.As shown in Figure 2, subscriber equipment is connected to same P-GW by 3GPP access network and WLAN simultaneously, the service flow packet accessed by 3GPP access network flows 1 containing voice IP, conventional video stream 2, non-traditional video flowing 3, the Business Stream accessed by wlan network comprises Web service stream 4 and file transfer protocol (FTP) (FTP, FileTransferProtocol) flows 5.When subscriber equipment moves to the more weak region of the quorum sensing inhibitor of WLAN, the transmission quality of the Business Stream accessed by WLAN is affected, and the transmission quality flowed from the IFOM flow process that WLAN access moves to the access of 3GPP access network to improve Web by Web stream initiated by subscriber equipment.Fig. 3 is Business Stream access EPC schematic diagram after migration.As shown in Figure 3, after migration, Web flows through the access of 3GPP access network.
According to the mobility management protocol type that user uses, stream migration is divided into the stream migration of Host Based mobility management protocol (such as DSMIPv6) and the stream migration of network mobility management protocol (such as GTP/PMIPv6).
Current 3GPP can support the stream migration based on DSMIPv6, subscriber equipment and network are by two stack mobile IP v 6 (DSMIPv6, Dual-StackMobileIPv6) signaling carries out the negotiation of stream migration information, completes the stream migration routing rule information that subscriber equipment and network amendment after the negotiation of stream migration information are corresponding.Stream migration based on DSMIPv6 is all initiated by UE.UE can be linked into same P-GW by 3GPP access network and non-3 GPP access network (such as WLAN) simultaneously simultaneously, P-GW is that UE distributes an IP address, this IP address uses simultaneously on 3GPP access network and non-3 GPP access network, can the migration of supporting business stream between 3GPP access network and non-3GPP access network, such as: during UE is simultaneously by 3GPP access network and non-3GPP access network access EPC, if UE is moved, not in the overlay area of non-3GPP access network signal, but still in the overlay area of 3GPP access network signal, then the service flow transfer accessed by non-3 GPP access network can be accessed to by 3GPP access network, or if non-3GPP network congestion, UE can by service flow transfer high for requirement of real-time to 3GPP network.
At present, 3GPP is studying network mobility management protocol (NB-IFOM, Network-basedIPflowmobility) (such as general packet radio service technology (GPRS, GeneralPacketRadioService) tunnel protocol (GTP, GPRSTurningProtocol)/proxy mobile IPv 6 (PMIPv6, ProxyMobileIPv6)) stream migration (IPflowmobility).UE uses GTP/PMIPv6 to be linked into EPC by 3GPP access network and non-3GPP (e.g.WLAN) access network, 3GPP network and non-3GPP network are that UE distributes identical IP address, can be realized the stream migration on 3GPP access network and non-3GPP access network between UE and EPC by renewal (increase newly, delete or amendment) stream migration routing rule.When needing to carry out stream migration, the stream migration routing rule that UE can provide according to access network discovery selection function (ANDSF, AccessNetworkDiscoverySelectFunction); Or according to the signal strength signal intensity of eating dishes without rice or wine; Or send stream migration routing rule, after EPC receives stream migration routing rule, according to the pre-configured routing rule of operator according to configuration information etc. to EPC; Or the routing rule that operator upgrades according to the current congestion situation of EPC; Or whether have precedence over EPC etc. according to UE and judge whether to upgrade stream migration routing rule, if upgraded, then send stream migration indication information to UE, otherwise send refuse information to UE.When needing to carry out stream migration, EPC also can according to the pre-configured routing rule of operator; Or the routing rule etc. that operator upgrades according to the current congestion situation of EPC sends stream migration routing rule to UE, after UE receives stream migration request, the stream migration routing rule that can provide according to access network discovery selection function (ANDSF, AccessNetworkDiscoverySelectFunction); Or according to the signal strength signal intensity of eating dishes without rice or wine; Or according to configuration information or whether have precedence over EPC etc. according to UE and judge whether to upgrade stream migration routing rule, if upgraded, then send stream migration indication information to EPC, otherwise send refuse information to EPC.
In the stream migration of network mobility management protocol, UE (or EPC) cannot the current network condition of perception EPC (or UE) when carrying out stream migration, such as, UE finds that WLAN signal sends stream migration routing rule to EPC after losing, after EPC receives stream migration routing rule, detect current network not congested, then send refuse information to UE, UE then cannot carry out stream migration after receiving refuse information, thus causes the transmission quality of the Business Stream of UE on WLAN to decline.
