Description

Obtain method and the access service router of positional information in the marked net

Technical field

The present invention relates to data communication technology field, relate in particular to the method, access service router, location register and the location register agency that obtain positional information in a kind of marked net.

Background technology

The Internet is extensive use, and has obtained huge success, but has some defectives in the network architecture and agreement, mainly is reflected in:

Mobility support to terminal is not enough, and there is the route detour problem in prior art;

Do not support user identity to separate with the network site;

There is safety problem, can not guarantees customer location privacy etc.

Marked net is a kind of novel internet technique, introduce the thought that separate the identity position, support mobile access terminal mobility and continuity, especially each user has unique permanent identification in the marked net, network all needed identity is verified when the user accessed at every turn, so network can guarantee authenticity and the reliability of this identify label.Based on this unique reliable identify label, can set up the Identity Management system, carry out the business based on user identity management, improve network security.

The basic principle of marked net is to be the fixing identify label of user equipment allocation, use identify label to replace Internet protocol of the prior art (Internet Protocol between the subscriber equipment, abbreviation IP) address communicates, and by the station location marker of the access service distributing user that is positioned at the edge, the Internet, the use location sign is carried out route, and the mapping between completing user identify label and the station location marker and conversion

Fig. 1 shows the framework of marked net, for being described as follows of each entity among Fig. 1:

Subscriber equipment 101 (User Equipment, be called for short UE), support the subscriber equipment of Internet protocol access, comprise that mobile grouping field accesses terminal, supports wireless local function terminal, fixedly accesses terminal etc., comprise further that also the business such as application server provides equipment.UE user access identity sign (Access Identity is called for short AID) replaces the IP address, provides and communicates with other subscriber equipmenies of network, business.

Access service router one 02 (Access Service Router, be called for short ASR), the access network at UE 101 places and the interface equipment between the Internet, be responsible for authentication, customer location sign (the Routing Identity of UE 101, be called for short RID) management, AID and RID mapping and conversion, and the functions such as the encapsulation/deblocking of user data, forwarding.

Generic router 103 (Common Router is called for short CR) is finished the calculating of Routing Protocol, and according to RID forwarding data bag.

Location register 104 (Location Register is called for short LR) is preserved the mapping relations between AID and the RID, query function is provided, and the package forward function can be provided.

Fig. 2 is a business procedure in the marked net, supposes that UE-A is client, and UE-B is service end, may further comprise the steps:

Step 201, UE-A successfully are registered to the ASR-A in access zone, comprising adhere to, authentication, authentication, and AID assigning process, detailed process depends on Access Network.Wherein AID also can be based on terminal static configuration mode and realizes;

Step 202, ASR-A are that UE-A distributes RID, and send address mapping circular message to LR, the mapping relations of wherein carrying RID and AID, and LR preserves the identity position mapping relations (AID-A, RID-A) of UE-A;

RID is generally the routing address of ASR.

Step 203, ASR-A also preserve the identity position mapping relations (AID-A, RID-A) of this end subscriber UE-A in this locality;

Step 204～206, UE-B are linked into ASR-B, ASR-B is to the RID of LR circular UE-B and the mapping relations of AID, LR preserves identity position mapping relations (AID-B corresponding to UE-B, RID-B), ASR-B also preserves the identity position mapping relations (AID-B, RID-B) of this end subscriber UE-B in this locality;

UE-A and UE-B can not be the same access technologies.

If step 207 UE-A needs and UE-B communicates, then the identify label take own identify label AID-A as source address, opposite end is as destination address, and structure IP packet sends to ASR-A;

{ source address=AID-A, destination address=AID-B, data load }

Step 208, ASR-A are according to the inquiry of the purpose AID-B in packet identity position, opposite end mapping relations cache table, and whether inquiry exists mapping relations corresponding to AID-B, if execution in step 209, otherwise execution in step 214 are not hit in inquiry;

If the user that UE-A or ASR-A access then may have the buffer memory of (AID-B, RID-B) mapping relations communicating by letter with UE-B in the recent period among the ASR-A.

Step 209, ASR-A send the position enquiring request to LR, positional information corresponding to inquiry opposite end identity AID-B;

The AID-RID mapping relations table that step 210, LR inquiry are preserved obtains RID-B corresponding to AID-B;

Step 211, LR return inquiry response to ASR-A, carry Query Result RID-B;

Step 212, ASR-A encapsulated data packet also send to ASR-B by generic router;

Packaged type be with UE-A station location marker RID-A as source address, the station location marker RID-B of UE-B is as destination address, and will contain the raw data packets such as AID-A and AID-B and data load as the new data load that make up packets;

{ source address=RID-A, destination address=RID-B, data load { AID-A, AID-B, initial data load } }

The identity position mapping relations (AID-B, RID-B) of step 213, ASR-A buffer memory opposite end, the follow-up like this UE-B data that send to, ASR-B does not just need the inquiry to LR, just can directly encapsulate and send to ASR-B;

After ASR-B receives packet, execution in step 215.

If there are the mapping relations to end subscriber AID-B and RID-B among step 214 ASR, then to hit during the mapping relations buffer memory of step 208 inquiry identity position, opposite end, the ASR-A encapsulated data packet also sends to ASR-B by generic router;

Step 215, ASR-B deblocking packet are reduced into the initial packet that UE-A sends, and obtain the mapping relations of AID-B and AID-A and RID-A, then according to AID-B with Packet Generation to UE-B;

{ AID-A, AID-B, data load }

The identity position mapping relations (AID-A, RID-A) of step 216, ASR-B buffer memory opposite end UE-A, the follow-up like this packet that sends to UE-A, ASR-B just do not need the inquiry to LR, can directly encapsulate and send to ASR-A.

The processing procedure of packet that UE-B sends to UE-A is identical.

Can find out from the analysis of top, use AID identifying user identity in marked net, separating of identity and position realized in the position that the RID identifying user is current.Only have AID information in user equipment side, do not have RID information, namely user equipment side only has identity information, and does not have positional information; The existing subscriber identity information of network side also has the information of position, and safeguards mapping relations between the two, finishes translation function.

In Internet service, some service needed provides the Extraordinary service according to user's position, as the informations such as the on-site news of user, weather are provided for the user; Some service needed is selected suitable service node or routed path according to customer location, realize nearby service or path optimization, reduce that unnecessary path takies or circuitous, provide customer service to experience, some business also needs to obtain mobile subscriber's change in location in addition.

Such as in the internet content distribution service, at network edge a plurality of caching server (CacheServer are set, be called for short CS), network based certain control strategy is distributed to caching server with the needed resource of user (such as streaming media resource, file downloaded resources) from source server; When the user controls the node request resource to resource, resource control node is derived the user in the position of network according to user's IP address, then select one or more caching servers according to the position, and notify the user, the user is Gains resources from above-mentioned caching server, thereby has realized flow optimization, takies less the resource of backbone network as far as possible, because the network site of distance users is closer, also improved user's experience simultaneously.

But in marked net, the business relevant with the user on-position such as content distributing service, just has problems, and Fig. 3 is that content distributing network is disposed schematic diagram in marked net.

Marked network connects a plurality of edge access territory, and content distributing network is deployed with caching server in different edge access territories.UE is from input field 1 access, to resource control node request resource, owing to only containing user's identity information AID in the request, resource control this moment node can't obtain accurately on-position of user, therefore can't distribute suitable caching server nearby for the user, such as the caching server in the input field 1, or the caching server in the input field 2 nearby.If caching server is some random access nodes in addition, serve as such as subscriber equipment, resource control node also needs to instruct the network site of these caching servers.

As can be seen from the above analysis, because marked net has been introduced the thought that separate the identity position, come identity and the position of identifying user with AID and RID, but in the edge access network, only has identity information, and there is not positional information, can't satisfy professional business demand relevant to the network insertion position, therefore need the capable network location information that the user is provided for the business of its carrying of marked net.
