Description
Technical field
The present invention relates to the communications field, in particular to a kind of stream migration method and device.
Background technology
Along with the development of communication network and the generally use of multimode terminal, various data services sharply develop, for example, web page browsing, game on line, media-on-demand etc., the user has had explosive growth on the data service flow, requirement to the business experience aspect is also more and more higher, and carrier network pressure is also increasing, due to the multi-user simultaneously the network congestion problem that causes of usage data business be on the rise.
Some non-third generation partner programs (3rd Generation Partnership Project, referred to as 3GPP) network, WLAN (Wireless Local Area Network for example, referred to as WLAN), possess low cost, high bandwidth, the good characteristics of focus covering, be subject to the favor of operator.WLAN is widely deployed in hotel, coffee shop, airport, conference centre and large-scale public place, is provided to the access of Internet and self-operated business network for the user.Wlan network is current as the substituting and the means of supplementing out economy of 3G technology, can to help operator to solve on 3G network data traffic aspect the data service shunting excessive, takies Radio Resource too much and the overweight problem of network load.WLAN and 3G mobile network's fusion, the technology such as Wifi shunting (Offload) and stream migration are extensively proposed at present, in order to can utilize more effectively fully wireless network resource, reduce the network operation cost, for the mobile subscriber provides abundant business and better experience.
Operator wishes to use and need not that terminal participates in, solved the problem of network side traffic overload by the self-determining stream migration of network side, for example: terminal is simultaneously by after 3GPP and Non-3GPP (as: WLAN) access network, and the IP of miscellaneous service stream is transmission in 3GPP and Non-3GPP (as: WLAN) access respectively.Sometime, the user has initiated the downloading service of file transfer protocol (FTP) (File Transfer Protocol is referred to as FTP) from the 3GPP access.Due to carrying out of ftp business, the load of 3GPP access increases the weight of, and in order to guarantee the normal access of other business, the IP stream of non-conversational class video traffic and web access business moves to non-3GPP access (for example, WLAN) in succession.After the FTP downloading service finished, the IP of non-conversational class video traffic and web access business stream moved back again the 3GPP access.At present, prior art has also had the use of proposition proxy mobile IPv 6 (Proxy Mobile IPv6 is referred to as PMIPv6) agreement, is carried out process and the method for stream migration by local mobile anchor.Fig. 1 is the representative network Organization Chart according to the proxy mobile IPv 6 agreement of correlation technique, as shown in Figure 1, the PMIPv6 core functional entities is local mobile anchor (Local Mobility Anchor, referred to as LMA) and Mobile Access Gateway (Mobile Access Gateway is referred to as MAG).LMA is responsible for safeguarding the state of reachability of mobile node (Mobile Node is referred to as MN), and is the topological anchor point of MN home network prefix.MAG represents that MN carries out the entity of mobile management, and it surveys the movement of MN, and the initialization binding registration.When having MN initially to access, MAG can send an agent binding update (Proxy Bind Update, referred to as PBU) message is used for upgrading the current location information of MN to the LMA of MN, and this PBU message also can initiatively be initiated to be used for upgrading to LMA by MAG the information of MN.
PMIPv6 allows MN to be connected to identical PMIPv6 territory by different interfaces, namely from different MAG access LMA.Fig. 2 is connected to the schematic diagram in identical PMIPv6 territory by different interfaces according to the MN of correlation technique, as shown in Figure 2, if1 is interface 1, and if2 is interface 2, MN accesses the PMIPv6 territory simultaneously by MAG1 and MAG2, and network will be the one group of unique prefix of each interface assignment that connects.From the angle of MN, whole PMIP territory is exactly a single link, and network will guarantee that MN can not survey the variation of its 3 layers of connections, even MN has changed its tie point.
When LMA determined a stream (a certain MAG) from the one paths is migrated to another path (another MAG), this process became IP stream mobility.Usually, described anchor point network element can be called Mobility Management Entity.Realize stream migration, the triggering of stream migration is a key issue.Only clear and definite under the prerequisite of stream migration trigger mechanism, LMA could carry out stream migration, and the forward-path of Business Stream is migrated to another access network from a certain access network of multimode terminal.
Fig. 3 is initially connected to the signaling process figure of network according to MN in the PMIPv6 agreement of correlation technique, as shown in Figure 3, comprise that following step S302 is to step S314.
At first step S302, MN send router solicitation (Router Solicitation is referred to as RS) message.
Step S304, MAG send a PBU message and are used for upgrading the LMA place about the current location information of MN to the LMA of MN.
Step S306, when LMA received this PBU message, LMA was that MN distributes home network prefix (HomeNetwork Prefix is referred to as HNP), simultaneously, LMA also can generate a BCE and be established to the end node of the bidirectional tunnel of MAG.
Step S308, the LMA loopback includes the PBA message of MN-HNP.
Step S310, when MAG received PBA message, it can be established to the end node of bidirectional tunnel of LMA and the forwarding mechanism of MN communication.At this moment, MAG has all the essential information of home link (Home Link is referred to as HL) for simulation MN.
Step S312, MAG announces the HNP of MN as the prefix on the link of main frame by sending router advertisement (Route Advertisement is referred to as RA) message to the MN on access link.
Step S314, when receiving RA message as MN on access link, it can by the pattern of the permission of the RA message indicating on corresponding access link, namely have state or stateless address configuration pattern to configure its interface IP address.After address configuration success, MN can obtain to be derived from one or more addresses of its HNP.After the address configured into, MN had the one or more effective address of the HNP that is derived from it.MAG and LMA also have suitable routing state for the treatment of the load that sends to and come from the MN that is obtained disposing one or more addresses by HNP.
As the topological anchor point of MN-HNP, LMA receives the message that is sent to MN.LMA is sent to MAG by bidirectional tunnel.As the MAG of the tunnel other end, after receiving message, remove outside head, and be forwarded to MN.PBU information also can initiatively be initiated to be used for to LMA by MAG the information of renewal MN.
But, the network side stream migration that proposes at present triggers, to trigger the execution stream migration by LMA according to conditions such as carrier policy and the signing attributes of user, because LMA can't know that the residing non-3 GPP access network of MN (for example: concrete network state information wlan network), if the residing non-3 GPP access network link-quality of user terminal is very poor or the load is excessive, if at this moment LMA also with service flow transfer in non-3 GPP access network, the message dropping of the stream after probably causing moving has reduced user's experience.
