Description
Technical field
The present invention relates to communication technical field, particularly relate to a kind of listing maintenance, system and IAD router.
Background technology
Existing internet widely used transmission control protocol/internet protocol (TransmissionControl Protocol/Internet Protocol, TCP/IP) in, IP address has dual-use function, both as the station location marker of communication terminal host network interface in network topology of network layer, again as the identify label of transport layer host network interface.ICP/IP protocol does not consider the situation of host mobility at the beginning of design.But when host mobility is more and more general, the semanteme overload defect of this IP address is day by day obvious.When the IP address of main frame changes, not only route changes, and the identify label of communication terminal main frame also changes, and routing overhead will be caused so more and more heavier, and the change of host identification also will cause application and the interruption be connected.
The object that identify label and position separation problem propose is the problems such as semanteme overload in order to solve IP address and routing overhead be serious, the dual-use function of IP address is separated, realizes mobility, many locals property, the dynamic code reassignment in IP address, alleviate the support of the problems such as exchanging visit in routing overhead and Next Generation Internet between heterogeneous networks region.
In the prior art, propose a kind of network identify label and position separation scheme (being called for short marked net below), the basic thought of this scheme is: network is divided into Access Layer and core layer, mobile node in network has two kinds of identity type: User Identity (Access Identifier, be called for short AID) and route location mark (Routing-Location Identifier is called for short RID).For each user in network configures unique AID, this AID remains constant in moving process; In data forwarding process, AID can only use at Access Layer, and RID can only use in core layer; Between user terminal during application layer communication, AID is used to identify opposite end.
The topological schematic diagram of above-mentioned network identify label and position split-frame as shown in Figure 1, in this network identify label and position split-frame, mainly comprise: wireless access network (RAN) 11, IAD router (Access Gateway Router, be called for short AGR) 12, broad sense gateway router (General Switch Router, be called for short GSR) 13, mapping server (Identifier MappingServer, be called for short IDMS) 14 and authentication center 15 etc.; Wherein:
AGR, is responsible for various mobile node and provides access service, for the user of access distributes RID, and transmits in backbone network after the data message of user being carried out mark encapsulation.
AGR is when receiving the data message that terminal is sent, inquire about the AID-RID mapping table in local cache (CACHE) according to destination address in data message (i.e. the AID of Correspondent Node): if find corresponding AID-RID map entry, then the RID of the communication terminal found is encapsulated in header and is sent to backbone network and carries out forward process; If do not find corresponding AID-RID map entry, then by data message forwarding to backbone network, and the flow process of inquiry (Correspondent Node) AID-RID map information is initiated to IDMS, and AIDc-RIDc mapping IDMS being returned correspondence is kept at this locality, inquires about when forwarding in order to subsequent packet.
Or, AGR is not when finding corresponding AID-RID map entry, also can select not by data message forwarding to backbone network, but the flow process of inquiry (Correspondent Node) AID-RID map information is initiated to IDMS, return after corresponding AIDc-RIDc maps until IDMS, the RID of the communication terminal found is encapsulated in header and is sent to backbone network and carries out forward process.
AGR, when receiving the data message mailing to terminal, carries out decapsulation process to data message, peels off the heading comprising RID newly-increased in data message, mails to terminal.
The major function of GSR carries out routing and forwarding data packets according to the route location mark RID in data message.
The mapping relations of User Identity and station location marker in IDMS primary responsibility maintaining network, and provide inquiry service to IAD router and other mapping server.
Authentication center, is responsible for the information such as recording user classification, user's grade of service, carries out legitimacy authentication and authorization when user accesses to user.Bi-directional authentification between authentication center's network enabled and user.
Wireless access network, is responsible for providing two layers of link also between maintenance customer's terminal to IAD router-A GR; RRM is responsible in cellular mobile network application scenarios.
The method of the handover management realizing mobility support under the above-mentioned network architecture is described below, Correspondent Node (the Correspondent Node of mobile node, be called for short CN) and mobile node (Mobile Node, be called for short MN) set up communication, mutual transceiving data message, setting up in the process of correspondence with MN, the AGR at CN place can according to the AID carried in the message of MN, inquire about the mapping relations of AID and RID of MN to mapping server IDMS, thus obtain the route location mark RID of MN; Simultaneously the AGR at CN place is at AID and the RID mapping relations table (abbreviation mapping table) of local maintenance MN, and form is as shown in the table:
The opposite end identity position identity map table of table 1 IAD router
| AID1 | RID1 |
| AID2 | RID2 |
| ... | ... |
After wireless access network detects the mobility (namely the position of MN there occurs change, is moved to another AGR from an AGR coverage, needs in this case to initiate switching flow) of MN, trigger switching flow.In handoff procedure, cut out gateway A GR and set up forwarding relation with incision gateway A GR, in handoff procedure or after having switched, cutting out gateway A GR by the data message forwarding mailing to MN received to cutting gateway A GR, being transmitted to MN by cutting gateway A GR.
The new mapping relations of MN, after switching completes, are notified the IAD router at all CN places by the route detour problem after switching by incision gateway.Like this, follow-up message just directly can be sent to the incision gateway of MN by the IAD router at CN place, avoids route roundabout.
Therefore, being the information that each local MN accessed preserves all CN with regard to needing at IAD router, according to the information of preserving, identity map relation new for MN being informed to the IAD router at CN place.
In concrete enforcement, first require that IAD router can preserve the record (being called for short opposite end table) of the Correspondent Node of the user terminal of all this locality access, next requires that all IAD routers are independent or can notify the couple in router that Correspondent Node accesses under the help of mapping server.If mapping server can not provide the help forwarding notice, so IAD router just must preserve the information of the IAD router at Correspondent Node place.Table 2 and table 3 are this locality access mapping table of IAD router preservation in this case and a kind of organizational form of Correspondent Node mapping table.
The local access terminal identification mapping table of table 2 IAD router
The Correspondent Node identity map table of table 3 IAD router
| Opposite end AID1 | Opposite end RID1 | The IAD router of Access Network | Timer |
In table 2 and table 3, the record of Correspondent Node also needs to arrange timer, if decide do not have the record just should deleting this Correspondent Node that communicated with this Correspondent Node for a long time, to save memory headroom.
Mainly there is following problem in above solution:
AGR should safeguard mapping table, in order to mobility, also will safeguard that opposite end is shown for MN, and this takies very large to the memory headroom of AGR, and performance needs timer to carry out burin-in process, and overhead is also very large.
