Description

One kind stream policy management method on the move and system
Technical field
The present invention relates to moving communicating field, and in particular in a kind of multi-access systems, flows mobile policy management method And system.
Background technology
Fig. 1 shows a kind of architectures of communication networks based on location server, and terminal can be mobile terminal, fixed terminal With the one or more in roam terminals, such as mobile phone, landline telephone, computer and server.Access network is used to carry for terminal For two layers of (physical layer and link layer) access means, the physics access link between maintenance terminal and access gateway.Access gateway For for terminal distribution positional information, the mark and position map information of maintenance terminal to carry out location registration to location server The positional information of (alternatively referred to as location register) and inquiry terminal, and realize route and the forwarding of data message.Access gateway The positional information of distribution points to this access gateway, namely the address information comprising the access gateway, regard the positional information as number According to message destination address when, the data message will be routed to the access gateway.Location server is used to handle to terminal position Registration, cancellation and the inquiry of confidence breath, preserve and safeguard identity and the positional information map information of home subscriber terminal.
When terminal is communicated with opposite end, access gateway, which receives uplink data messages, will enter row positional information encapsulation and turn Hair.Specifically, in the positional information of local search Correspondent Node, such as inquire, regard the positional information of Correspondent Node as purpose Address, is encapsulated in the data message comprising terminal iidentification and Correspondent Node mark, warp by source address of the positional information of terminal Broad sense Forwarding plane is forwarded to the access gateway of Correspondent Node access.If inquiry is less than then to the service of Correspondent Node homing position The positional information of device query communication opposite end is simultaneously stored in local.At this point it is possible to encapsulate in messages after the above positional information of terminal, Broad sense Forwarding plane is forwarded to by mapping forward plane, or, connect after the positional information of Correspondent Node is inquired, then by this Function Access Gateway by it is above-mentioned in the positional information of local search to Correspondent Node when in the way of enter row positional information encapsulation and forward process. In down direction, access gateway, which is received, carries out solution positional information encapsulation after the data message that broad sense Forwarding plane is sent, peel off it In positional information after be sent to terminal.
As can be seen that access gateway in order to realize the normal forwarding of message, it is necessary to when terminal is accessed be the terminal distribution Positional information, to the position server registration positional information to update the positional information of the terminal of this in location server.Access network The mark and positional information map information for also needing to maintenance terminal and its Correspondent Node are closed, to realize the positional information envelope to message Dress.In one example, access gateway is each terminal maintenance terminal and the correspondence information of Correspondent Node, is claimed herein The correspondence relationship information identified for the terminal to client information, the opposite end packet containing the terminal iidentification with Correspondent Node, may be used also With the mark including the terminal and positional information map information, meanwhile, the unified Correspondent Node for safeguarding all terminals of access gateway Mark and positional information map information.Certainly, access gateway is that each terminal safeguards all Correspondent Nodes of the terminal respectively Mark and positional information map information it is also possible, wherein contain terminal to client information.Safeguard to client information, be in order to When terminal switches, incision side access gateway can determine which Correspondent Node is the terminal have, so as to communication pair Terminate into access gateway send the new positional information of the terminal to carry out location updating.The access gateway of Correspondent Node access Complete after updating, it is possible to which the data message that Correspondent Node is sent is routed directly to the access gateway that the terminal is switched to.
Because terminal there can be multiple connections simultaneously (as shown in Figure 2, Figure 3 and Figure 4), multiple accesses are now there may be Gateway is the multiple positional informations of terminal distribution, and for same terminal, a terminal iidentification pair is there may be in location server Answer the situation of multiple positional informations, due to be connected to set up during consider application or the characteristics of Business Stream, with business The association attributeses such as quality, charging, only allow to transmit corresponding application or Business Stream.In order to opposite end to terminal send data when pair Termination function Access Gateway can determine the correct route (i.e. corresponding access gateway) of data flow, strategic server will deposit with applying, Or business or the related policy information of connection or position, these information can (the i.e. plan based on terminal related to terminal iidentification Slightly), can also be unrelated with terminal iidentification, when opposite end sends data to terminal according to application or business or connection or position Feature or terminal iidentification provide the reference by location of terminal, and location server together routing, and are searched just for corresponding data flow True positional information.Strategic server can be connected with location server and/or access gateway, its position in a communication network With connected mode as shown in Figure 2, Figure 3 and Figure 4.
Because the factors such as load sharing, signal intensity, user intention, the network planning, operation maintenance cause user or net Some data flows are migrated or switched between access gateway by network, and data transfer path is modified.Now, to termination The access gateway that function Access Gateway is still routed data to before migration or switching, so that data transfer path can not be connected or number It can not be ensured according to transmission quality.
For PMIP scene, as shown in Figure 5 a be PMIP agreements logical architecture, including mobile node (Mobile Node, MN), Correspondent Node (Correspondent Node, CN), Mobile Access Gateway (Mobile Access Gateway, ) and local mobility anchor (Local Mobility Anchor, LMA) MAG.Wherein CN can be stationary nodes, can also It is mobile node, i.e., with corresponding MAG and LMA.MAG is MN the first hop router, and its main function is included in MN accesses Shi Weiqi distribution Care-of Address (Care of Address, CoA) and replacement MN perform the PMIP between MN anchor point LMA Bind (PMIP Binding).LMA is as MN anchor point, and its main function for MN including distributing home address (Home of Address, HoA) and the above-mentioned PMIP bindings of processing.The main purpose of the PMIP bindings performed between MAG and LMA is to allow both sides Know address, above-mentioned CoA and the HoA of other side, and will be stored in local.In addition, perform PMIP binding procedure in, also for MN establishes a bidirectional tunnel between MAG and LMA.What deserves to be explained is, the IP address that MN is finally got is that LMA is it The HoA of distribution.In common network design, MAG is normally at the relatively low position of topology, such as the edge positioned at Metropolitan Area Network (MAN)； And LMA is then normally at the higher position of topology, such as save the core of dry net.Between MAG and LMA actually often through Multiple router hopses are connected.
The mobile management of PMIP agreements is embodied in as MN mobile energy changes the MAG being currently connected to, and is kept simultaneously MN IP address (i.e. HoA) is constant.As shown in Figure 5 b, change the MAG that currently connects refer to from previously connected source MAG (sMAG, Source MAG) change/switching is connected to target MAG (tMAG, target MAG).After changing to tMAG, tMAG is MN A new CoA is distributed, and the PMIP between MN anchor point LMA is performed for MN and is bound, updates what both sides mentioned above preserved Information, and set up new bidirectional tunnel between t-MAG and LMA for MN.
Fig. 5 b show the process schematic that transmitting IP packet is received between MN and CN.As shown in Figure 5 b, the IP between MN and CN Data message has to pass through the tunnel between sMAG and LMA before the handover, and the tunnel between tMAG and LMA is had to pass through after handover Road.
The transmission path existed to solve existing PMIP mechanism wastes problem, a series of adverse consequences caused by entering, Need to transform existing PMIP mechanism, Fig. 5 c are improved PMIP protocol infrastructures.With the logic of existing PMIP agreements Framework (as shown in Figure 5 a) is compared, and the network element that improved PMIP protocol infrastructures are included remains as mobile node MN, communication pair Hold CN, Mobile Access Gateway MAG and mapping server (Mapping server, MAPS).Improved PMIP protocol infrastructures No longer there is LMA network elements.Wherein CN can be stationary nodes or mobile node, i.e., with corresponding MAG and MAPS.
MAG is MN the first hop router, and its main function for MN distribution in existing PMIP frameworks except delivering ground Location CoA, and replace the PMIP bindings between MN execution and MN MAPS outer, in addition it is also necessary to possess following function：
Inquired about to MAPS, obtain address or the CN Care-of Address for the MAG (MAG-CN) that Correspondent Node CN is currently connected CoA。
The IP datagram set up in MN MAG (MAG-MN) between CN MAG between bidirectional tunnel, forwarding MN and CN Text.
MAPS, which is remained, to be handled MN registrations, nullifies and more New function in LMA functions, distribution HNP ((Home Network Prefix, home network prefix) function, banding cache list (BCE, Binding Cache Entry) function is set up and safeguards, But not as MN anchor point, the IP datagram text between MN and CN, it is not necessary to pass through MAPS.MAPS needs to preserve current MAG-MN Address and/or MN CoA, it is and using MN as index, such as logical for MN using MN HoA or MN HNP as index Letter opposite end CN or CN MAG are inquired about according to MN relevant information.
When Fig. 5 d are shown using improved PMIP frameworks, the process schematic of transmitting IP packet is received between MN and CN.MN IP datagram text between CN is needed by the tunnel between MAG-MN and MAG-CN.When MN to CN sends up IP messages When, consistent with existing PMIP mechanism, MN needs IP messages being sent to MAG-MN.It is subsequently different from existing PMIP mechanism It is that MAG-MN needs to inquire about MAG-CN address.In the address (after such as MAG-CN IP address) for inquiring MAG-CN, MAG-MN With MAG-CN address as terminal, MAG-MN to MAG-CN tunnel (e.g., IP in IP tunnels) is set up, while by above-mentioned IP Message is placed in tunnel, is transmitted directly to MAG-CN.After MAG-CN receives the IP messages for transmitting and in tunnel, by IP messages It is sent to CN.It should be noted that MAG-MN can also inquire about CN CoA, replace above-mentioned MAG-CN's with CN CoA addresses Address, can also reach identical purpose.Now, MAG-MN uses CoA as terminal, sets up MAG-MN to MAG-CN tunnel, Effect is equal.Also what deserves to be explained is, MAG-MN inquire about MAG-CN address (or CN CoA) when, first in local cache Middle inquiry, if inquiry is less than again to inquiry on other network elements.For example, CN anchor point LMA (LMA-CN) can be arrived according to CN HoA To inquire about.Inquire after required result, Query Result is buffered in locally by MAG-MN again.Query Result is buffered in local Benefit is to be avoided that frequently to go to perform inquiry operation to other network elements.As a same reason, when CN is to MN transmission downstream IP messages, Using above-mentioned similar method, principle is identical, repeats no more.Using this method, the path that transmitting IP packet is received between MN and CN is changed into For MN<->MN MAG<->CN MAG<->CN, needs not move through MN (or MN and CN) anchor point LMA network elements.
Similarly, in the case where there are the PMIP terminals multiple connections to carry out stream migration or switching simultaneously, same end End carries out traffic locality information change in multiple access gatewaies, still occurs that opposite end can not obtain correct access gateway The problem of.
