Description
Technical field
The present invention relates to communication technical field, relate in particular to next generation network (NGN) system and realize mobility management method.
Background technology
Popularizing and using along with 2.5G/3G wireless network and broadband IP network, industry has proposed the notion (Next Generation Network) of next generation network, require the NGN can compatible all networks at present, can transmit all service medias, and for new business provides excellent interface and extended capability, and guarantee ubiquitous, the safety and favorable service quality (QoS) ability of communication.
NGN basic framework model as shown in Figure 1, whole network model is divided into service plane and transport plane.Transport plane is divided into 4 funtion parts again, network access control functions, resource admission control function, access network function and core transfer function.Wherein: network access facility partly comprises customer data base, checking and authorization function entity, network insertion configuration controlled function entity and location management function entity etc.; The resource admission control function comprises strategy decision functional entity, access-in resource controlled function entity and core transfer resource controlled function entity.
User terminal is connected to the NGN network by Access Network, and is subjected to the control of network access control functions entity.In network access control functions, checking authorized entity query subscriber database is carried out authentication vs. authorization to the user; After checking was passed through, the configuration controlled entity was configured (such as IP, DNS, Gateway etc.) to user's network characteristic; Location management function is collected user position information, upwards is sent to the relevant controlled entity of service plane.
The resource admission control function is accepted the scheduling of resource request from service plane, by strategy decision functional entity this resource request is decomposed into access network resource request and resources of core network request; Access network resource controlled entity and core transmission network resource control entity respectively will be separately request be interpreted as actual Internet resources bandwidth and represent and be handed down to related entities in Access Network and the core net.
The terminal transmission function to the terminal use can be opened/be closed to Access Network and core net after receiving the control request of network access control functions (NACF) and resource admission control function (RACF).
In addition, because information storage and acquisition capability that internet INTERNET has good communication capability, magnanimity, therefore, the basic technology-IP technology of constructing INTERNET just becomes the current technology of network, variously relevant fall over each other to use the IP technology, with the IP technical compatibility with incoherent network.On this basis, industry has proposed a kind of technology that is called mobile IP and has solved user's roaming and the problem of maintenance business continuance.Because the rapid expansion of INTERNET cause the IP address situation in short supply to occur, and very fast IP address will exhaust.For addressing this problem, on the basis of present IP technology (IPv4), developed IPv6; Corresponding mobile IP technology has also developed into MIP6 (Mobile IPv6) from MIP4.The basic principle of MIP6 is as shown in Figure 2:
(1) when mobile node is connected on its home network, it will take the mode the same with other stationary nodes to work.
(2) whether mobile node oneself roams on the field network by the neighbor discovery mechanisms detection of IPv6.The transmission router advertisement message in the nonlocal gateway meeting cycle of IPv6, the prefix that wherein comprises this field network, after mobile node is received the router advertisement message of nonlocal gateway, check that the prefix of field network wherein is different with the prefix of home network, then think to roam to field network.
(3) if when mobile node finds oneself to have moved on the field network, it will on the basis of the router advertisement information of receiving by there being the automatic layoutprocedure in state or stateless address to obtain Care-of Address on the field network.This moment, mobile node had home address and Care-of Address simultaneously.
(4) mobile node is registered to this Care-of Address of oneself on the home agent by " Binding Update " message.
(5) mobile node also can be given this Care-of Address its communication parter by " Binding Update " message registration notification.Before the registration, need to carry out earlier Return Routability testing process between mobile node and the communication parter, be that mobile node sends Home Init Test message and Care-of Init Test message earlier to communication parter, after the latter handles, return Home Test message and Care-of Test message and give mobile node.
(6) if the communication parter of mobile node is not known its Care-of Address, just will packet be sent on the home network of mobile node according to the home address of mobile node, its home agent will be truncated to these packets then, according to the mobile node present care-of address, utilize tunneling mechanism that these packets are transmitted to mobile node again.
Mobile node is issued the message of communication parter also can issue home agent by reverse tunnel earlier, hands to communication parter by home agent again.Because under this mode, the packet between communication parter and the mobile node all will come transfer by home agent, so be also referred to as " triangle route " mode.
(7) if communication parter is known the Care-of Address of mobile node by " Binding Update ", it will utilize the route header of IPv6 directly to send packet to mobile node.First destination address of packet is a Care-of Address, and second destination address is only home address, so packet can directly be issued the mobile node in the field network, and does not need through the home agent transfer.
On the rightabout, the source data packet address that mobile node is issued communication parter is a Care-of Address, and home address be kept at the destination of packet prolate-headed in.Like this, packet also can be issued home agent without reverse tunnel, but directly issues communication parter.This mode, " triangle route " mode of corresponding (6) is called " routing optimality " mode.
In the framework model of existing NGN, there be not the support of realization to mobile management; And present MIP6 technology mainly is aimed at a kind of technology that solves mobility problem of INTERNET network development, does not develop at the widespread demand of NGN network, and its control does not separate the framework of improper NGN network with transmission; Management mode and control model can not satisfy the demand of NGN network, and also do not support legacy network user terminal (PSTN user).Therefore, how MIP6 is fused among the NGN, so that support that in NGN mobile management becomes the problem that industry need solve.

After increase is used for the functional entity of mobile management in NGN, can carry out mobile management to portable terminal, its mobile management mainly comprises moving registration and moving switches.
The mobile subscriber need register to the checking authorized entity in local when the NGN network of local.When the mobile subscriber moves to field network, need register the identity of oneself to the checking authorized entity of the NGN network of visiting, return the registration response to the mobile subscriber after the checking authorized entity of visited network is verified the mobile subscriber, the mobile subscriber judges according to the result of registration response whether oneself can insert visited network.
After the mobile subscriber is linked into field network, use the service of moving if desired, also need identity to the functional entity registration that is used for mobile management oneself in its local.Comprise the new Care-of Address that mobile subscriber's oneself identity ID, the password that uses the service of moving and mobile subscriber obtain at visited network in the registration message.This registration message at first sends to mobile Delivery Function from the mobile subscriber, and mobile Delivery Function sends to mobile controlled entity after with this message encapsulation process, and mobile controlled entity sends mobile AAA entity with user ID in the message and password; Mobile AAA entity is sent to mobile subscriber with a reverse order with result with result.In this proof procedure, mobile controlled entity also sends query requests to the access network resource controlled entity, determining whether this mobile subscriber of enough resource and admissions, and the result is carried in the registration response.The mobile subscriber can move the registration response according to this and judge whether oneself can use the mobile communication service in local.
According to the fail safe needs, can the user not verified that in registration process consult shown in Figure 4ly, the main process that moves registration under this mode is as follows:
Step 400, the mobile subscriber server in the NGN network sends register command, and request inserts the NGN network.If when being positioned at field network, initiate register command to visited network.
Step 410, server are registered the user, and return the registration response signaling to the user.
Step 420, the mobile subscriber sends mobile register command after user registration success, and this moves register command and is sent to mobile controlled entity by the functional entity in the NGN network.
Step 430, mobile controlled entity are registered the mobile subscriber, and return the registration response to the mobile subscriber.
Step 440, the relevant information of mobile controlled entity after mobile Delivery Function transmits user's registration.
In the flow process of Fig. 4, the mobile register command that the mobile subscriber sends also can send to mobile Delivery Function, passes to mobile controlled entity by mobile Delivery Function, and its registration process in like manner repeats no more.
Set up the user of session for needs, move succeed in registration after can and communication user between set up the communication channel of a load plane.
In order to improve fail safe, can verify that in registration process consult shown in Figure 5ly, the implementation procedure that moves registration under this mode is as follows to the user:
Step 500, the mobile subscriber checking authorized entity (server) in the NGN network sends register command, and request inserts the NGN network.If when being positioned at field network, initiate register command to visited network.
Step 510, checking authorized entity obtain user data from customer data base the user are verified, the result sends corresponding registration response signaling to the mobile subscriber according to checking.
Step 520, after user registration success, the mobile Delivery Function of mobile subscriber in the NGN network sends mobile register command.
Step 530, mobile Delivery Function will receive that mobile register command hands to mobile controlled entity.
After step 540, mobile controlled entity are received mobile subscriber's register command, send querying command to moving the checking authorized entity.
Step 550, mobile checking authorized entity obtain user data from customer data base the user are verified, and will verify that the result sends to mobile controlled entity.
Step 560, mobile controlled entity send different registration reply messages to mobile Delivery Function according to different checking results.
Step 570, mobile Delivery Function return the registration response to the mobile subscriber.
In the flow process of Fig. 5, the mobile subscriber also can send mobile register command and be delivered to mobile controlled entity by other functional entitys in the NGN network, and it moves registration process and consults Fig. 4.
Set up the user of session for needs, move succeed in registration after can and communication user between set up the communication channel of a load plane.
When the mobile subscriber is in the network boundary of home network and field network, or when being in network boundary between the field network, link layer will report a handover event to network.After mobile subscriber's network layer is received this handover event, will send to current couple in router and act on behalf of route requests to obtain the information of adjacent access router.After learning the router address that oneself will insert as the mobile subscriber, to carry out authentication or mandate to the checking authorized entity under this router and (, then not need to carry out this proof procedure if the checking Authorized Domain under this couple in router is identical with the checking Authorized Domain before switching.)。After the mobile subscriber obtains the authorization, initiate handoff request to current couple in router, this current couple in router is handled this request and is sent switching initialization message to the target couple in router; The target couple in router is verified processing to this message after receiving this switching initialization message, and echo reply is given mobile subscriber's current couple in router; Current couple in router sends to the mobile subscriber with the result.If the mobile subscriber receives replying of handover success, then the mobile subscriber has obtained the passage of target couple in router.
Afterwards, the mobile subscriber carries out mobile register flow path.Move in the registration message of service entities to the local the mobile subscriber, comprised current Care-of Address and the home address that obtains from visited network of mobile subscriber.If user rs authentication is passed through, so mobile controlled entity will be set up the mapping relations of mobile subscriber's Care-of Address and home address in inside, and these mapping relations are handed down to mobile Delivery Function.If in the inner old home address of this mobile subscriber and the mapping relations of Care-of Address of existing of mobile controlled entity, mobile controlled entity and Delivery Function are then deleted these mapping relations.Set up the mapping relations of home address and Care-of Address at mobile Delivery Function after, the functional entity of resource access control part also needs to inquire about this mobile subscriber's user data, and corresponding bandwidth information, quality of service information etc. are handed down to mobile Delivery Function.
Like this, just set up the communication channel of a mobile Delivery Function of process between mobile subscriber and opposite end communication user: communication information sends to mobile Delivery Function from the mobile subscriber, this message process of passing through tunnel processing; Mobile Delivery Function is sending to the opposite end communication user with this message after it is gone the tunnel encapsulation; From message that end subscriber is come the flow process of process just in time opposite with it.
After building up this new communication port, mobile subscriber and to the old communication channel immediate cancel between the end subscriber, new channel enables, and mobile switching is finished.
After the mobile subscriber finishes switching, the mobile subscriber with what set up between to end subscriber is to move the long path communication channel of Delivery Function through home network.After the mobile subscriber roams field network, have the mobile subscriber with between end subscriber one directly without mobile Delivery Function than short path.Therefore, in order to optimize the path, after mobile switching was finished, the mobile subscriber sent the routing optimality request of oneself and arrives end subscriber, this request message comprises the mapping relations between mobile subscriber's home address and the up-to-date Care-of Address, and the source address of this request message is up-to-date Care-of Address.After end subscriber was received this request message, if accept this routing optimality request, then portion kept this mapping relations within it, eliminated this home address mapping relations in the past; And the transmission routing optimality is replied to the mobile subscriber.The communication channel through routing optimality between mobile subscriber and the communication user has just been set up like this; The destination address of the message that the mobile subscriber sends is exactly to end subscriber, and the destination address that end subscriber is sent message is exactly mobile subscriber's a up-to-date Care-of Address; No longer needing to move Delivery Function by the local of switching the user between the both sides communicates by letter.
Consult shown in Figure 6ly, portable terminal switches to field network and optimizes the main flow process of communication route following (with registration time verify and succeed in registration be example) from home network:
Portable terminal A in step 600, the NGN network sends to current couple in router and acts on behalf of route requests.
Step 605, described current couple in router return to portable terminal A acts on behalf of route announcement.
Step 610, the portable terminal A checking authorized entity (server) in the NGN network sends register command, and request inserts the NGN network.If when being positioned at field network, initiate register command to visited network.
Step 615, checking authorized entity obtain user data from customer data base the user are verified, checking is by sending corresponding registration response signaling (if current couple in router is identical with checking Authorized Domain under the target couple in router to portable terminal A, then do not need to carry out step 510 and 515, be expressed as dotted line among the figure).
Step 620, portable terminal A send handoff request to current couple in router.
Step 625, described current couple in router send the switching initialization request to the target couple in router.
Step 630, target couple in router return handover acknowledge to current couple in router.
Step 635, current couple in router return handover acknowledge to portable terminal A, and so far, portable terminal A obtains IP address (being Care-of Address) from the target couple in router.
Step 640, the portable terminal A mobile Delivery Function in the NGN network sends mobile register command, has comprised current Care-of Address and the home address that obtains from visited network of mobile subscriber in this signaling.
Step 645, mobile Delivery Function will receive that mobile register command hands to mobile controlled entity.
After step 650, mobile controlled entity are received the register command of portable terminal A, send querying command to moving the checking authorized entity.
Step 655, move the checking authorized entity and obtain user data from customer data base the user is verified, checking by and the result sent to mobile controlled entity.
Step 660, mobile controlled entity send the registration response to mobile Delivery Function, and simultaneously, mobile controlled entity is set up the mapping relations of mobile subscriber's Care-of Address and home address in inside, and these mapping relations are handed down to mobile Delivery Function.
Step 665, mobile Delivery Function return the registration response to the mobile subscriber; Then, portable terminal A sets up communication channel by the portable terminal B of destination router and opposite end.
Step 670, portable terminal A send optimization request to the portable terminal B of opposite end, and this request message comprises the mapping relations between portable terminal A home address and the up-to-date Care-of Address, and the source address of this request message is up-to-date Care-of Address.
The portable terminal B of step 675, opposite end returns to optimize to portable terminal A and replys; Then, two parties communicates by the passage after optimizing.
