Description

The method and access service router of positional information are obtained in mark net

Technical field

The present invention relates to obtaining the method for positional information in data communication technology field, more particularly to a kind of mark net, connecing Enter service router, location register and location register agency.

Background technology

Internet extensive use, and huge success is achieved, but exist in the network architecture and agreement Defect, is mainly reflected in：

Mobility support to terminal is not enough, and prior art has route detour problem；

Do not support that user identity and network site separate；

There is safety problem, it is impossible to ensure customer location privacy etc..

Mark net is a kind of new internet technique, introduces the thought that identity position is separate, and supports mobile access eventually Each user is owned by unique permanent identification in end mobility and continuity, especially mark net, and user accesses every time When network be required for verifying identity that therefore network ensure that the authenticity and reliability of this identity.It is based on This unique reliable identity, can set up Identity Management system, carry out the business based on user identity management, improve net Network safety.

The general principle for identifying net is the identity fixed for user equipment allocation, and identity mark is used between user equipment Know and communicated instead of Internet protocol of the prior art (Internet Protocol, abbreviation IP) address, and by positioned at mutual The station location marker of the access service distributing user at networking edge, is route, and complete User Identity using station location marker Mapping and conversion and station location marker between,

Fig. 1 shows the framework of mark net, is described as follows for each entity in Fig. 1：

User equipment 101 (User Equipment, abbreviation UE), the user equipment for supporting Internet protocol to access, including Mobile grouping field access terminal, support wireless local function terminal, fixed access terminal etc., still further comprise application server Equipment is provided etc. business.UE identifies (Access Identity, abbreviation AID) and replaces IP address, same net using user's access identity Network other users equipment, business are provided and communicated.

Access service router 102 (Access Service Router, abbreviation ASR), is the access network where UE 101 Interface equipment between network and internet, is responsible for certification, customer location mark (the Routing Identity, abbreviation of UE 101 RID) management, AID and RID mapping and change, and user data the function such as encapsulation/deblocking, forwarding.

Generic router 103 (Common Router, abbreviation CR), completes the calculating of Routing Protocol, and forward according to RID Packet.

Location register 104 (Location Register, abbreviation LR), preserves the mapping relations between AID and RID, carries For query function, it is possible to provide packet forwarding capability.

Fig. 2 is a business procedure in mark net, it is assumed that UE-A is client, and UE-B is service end, including following step Suddenly：

Step 201, UE-A are successfully registered to the ASR-A of access area, including attachment, certification, authentication, and AID Assigning process, detailed process depends on access network.Wherein AID can also be realized based on terminal static configuration mode；

Step 202, ASR-A be UE-A distribute RID, and to LR send address of cache circular message, wherein carry RID and The mapping relations of AID, 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 are also locally preserving the identity position mapping relations (AID-A, RID-A) of this end subscriber UE-A；

Step 204~206, UE-B are linked into ASR-B, and ASR-B circulates a notice of the mapping relations of the RID and AID of UE-B, LR to LR The corresponding identity position mapping relations (AID-B, RID-B) of UE-B are preserved, ASR-B is also locally preserving the body of this end subscriber UE-B Part position mapping relations (AID-B, RID-B)；

UE-A and UE-B can not be same access technology.

If step 207, UE-A need and UE-B is communicated, with the identity AID-A of oneself as source address, right The identity at end is purpose address, builds IP packets, is sent to ASR-A；

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

The purpose AID-B inquiry opposite end identity position mapping relations cache tables of step 208, ASR-A in packet, look into Whether inquiry is the presence of the corresponding mapping relations of AID-B, if inquiry is without hit, performs step 209, otherwise performs step 214；

If the user that UE-A or ASR-A are accessed communicated in the recent period with UE-B, may there be (AID- in ASR-A B, RID-B) mapping relations caching.

Step 209, ASR-A send position enquiring and ask to LR, the corresponding positional informations of inquiry opposite end identity AID-B；

The AID-RID mapping tables that step 210, LR inquiries are preserved, obtain the corresponding RID-B of AID-B；

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

Step 212, ASR-A encapsulated data packets are simultaneously sent to ASR-B by generic router；

Packaged type is that the station location marker RID-B of UE-B is used as destination using UE-A station location markers RID-A as source address Location, and the raw data packets such as AID-A and AID-B and data load as the new data load for building packet will be contained；

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

Step 213, ASR-A cache the identity position mapping relations (AID-B, RID-B) of opposite end, are so subsequently sent to UE-B data, ASR-B avoids the need for being inquired about to LR, it is possible to directly encapsulate and be sent to ASR-B；

After ASR-B is connected to packet, step 215 is performed.

If there being the mapping relations of peer user AID-B and RID-B in step 214, ASR, step 208 inquiry opposite end Hit when identity position mapping relations are cached, ASR-A encapsulated data packets are simultaneously sent to ASR-B by generic router；

Step 215, ASR-B deblocking packet, be reduced into UE-A transmission initial packet, obtain AID-B and The mapping relations of AID-A and RID-A, then deliver a packet to UE-B according to AID-B；

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

Step 216, ASR-B cache the identity position mapping relations (AID-A, RID-A) of opposite end UE-A, so follow-up to send To the packet of UE-A, ASR-B avoids the need for being inquired about to LR, can directly encapsulate and be sent to ASR-A.

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

Be can be seen that from the analysis of top and use AID to identify user identity in net is identified, RID mark users are current Position, realizes the separation of identity and position.There was only AID information in user equipment side, there is no RID information, i.e. user equipment side Only identity information, without positional information；The existing subscriber identity information of network side, also has the information of position, and safeguard both Between mapping relations, complete translation function.

In Internet service, some service neededs provide personalized service according to the position of user, such as user carries The informations such as news, weather for user location；Some service neededs select suitable service node according to customer location Or routed path, service or path optimization nearby are realized, reduce unnecessary path and take or roundabout, there is provided customer service body Test, some business also need to obtain the change in location of mobile subscriber in addition.

Such as in internet content distribution service, network edge set multiple caching servers (CacheServer, Abbreviation CS), resource (such as streaming media resource, file download resource) of the network according to required for certain control strategy by user from Source server is distributed to caching server；When user asks resource to resource control node, resource control node is according to user IP address derive user in the position of network, one or more caching servers are then selected according to position, and notify to use Family, user obtains resource from above-mentioned caching server, it is achieved thereby that flow optimization, takes the resource of backbone network less as far as possible, Simultaneously because the network site of distance users is closer, Consumer's Experience is also improved.

But in net is identified, the business relevant with user on-position, such as content distributing service there is problem, and Fig. 3 is Content distributing network disposes schematic diagram in net is identified.

Mark network connection multiple edge access domain, content distributing network is deployed with caching clothes in different edge access domains Business device.UE is accessed from input field 1, resource is asked to resource control node, due to comprising only the identity information of user in request AID, now resource control node cannot obtain the accurate on-position of user, therefore cannot nearby distribute suitable slow for user Deposit server, such as caching server in input field 1, or the caching server in input field 2 nearby.If other buffer service Device is some Stochastic accessing nodes, and such as user equipment serves as, and resource control node is also required to instruct the net of these caching servers Network position.

As can be seen from the above analysis, the thought of identity position separation is introduced due to mark net, is come using AID and RID Identify user identity and position, but in edge access network only have identity information, without positional information, it is impossible to meet with Business demand of the network insertion position about business, it is therefore desirable to identify the net that the business that net has the ability to be carried for it provides user Network positional information.
