Description
Related application
The application requires the U.S. Provisional Patent Application S.N.60/725 that is entitled as " WIRELESS TERMINALMETHODS AND APPARATUS FOR ESTABLISHING CONNECTIONS ANDBASE STATION METHODS AND APPARATUS FOR ESTABLISHINGCONNECTIONS (base station methods and the device that are used for wireless terminal methods and the device that connects and are used for connecting) " of submission on October 11st, 2005,589 rights and interests, this application is clearly included in this by reference.
Invention field
The present invention relates to communication system, relate in particular to the method and apparatus that connects at the cordless communication network such as cellular communications networks etc.
Background of invention
Communication system usually comprises a plurality of network nodes that are coupled to access node, is coupled to network such as the end node of mobile device etc. by these access nodes.Network node can be arranged into hierarchical structure.Access authentication and mandate (AAA) server is usually to be placed in relatively high-level node in this network level structure.They are provided for the information of fail safe and access control purpose usually.In the situation of using aaa server, access node usually has the safety chain with this type of server.This safety chain can pass the one or more nodes in this hierarchical structure.
Operator typically comes access session in the IP network management with radius protocol and the RADIUS aaa server that is associated.In the future, aaa server may be based on the New Deal such as DIAMETER etc.In the system that uses the RADIUS aaa server, when the user attempts to obtain access to carrier network, during the access session lasts, local-access router sends one or more RADIUS access requests to certificate server usually, authenticates this user with the request authentication server based on user's the identity such as network access identifier (NAI) etc.The AAA database usually will be allowed to access the service features that those users' of its system identity can call in company with them and store together.As user during by success identity, its access interface on access device is configured to have the Policy Status that the authorization of service with this user matches.This authorization of service is normally delivered to couple in router via RADIUS by authorization server.When being authorized, the service during the access session is used by the couple in router record, and uses the book keeping operation request message in the radius protocol to send to the billed services device as accounting records.The billed services device can be the part of aaa server, and perhaps it can be the separate server that uses identical agreement with authorization server.If the user is connected to a plurality of couple in routers during individual session, then these a plurality of sessions need to be assembled in the billed services device.
AAA system usually distributes (HoA), dynamic assignment HA (home agent), MN (mobile node) overview is distributed to couple in router and goes back distributing security keys with management ip address with Mobile IP (MIP) coupling and authenticates MIP message and protect airlink.Mobile node---namely can change the end node of its point of network attachment---and typically sends MIP message and obtain access to system, this triggering authentication and authorize the AAA request of this mobile node.AAA MN overview and fail safe state are delivered to couple in router with the service of control by this MN consumption from AAA system subsequently.
MN can change its point of network attachment, for example, and along with they move to another cellular cell and do this change from a cellular cell.This relates to the attachment point of MN is changed to the second access node such as the second router etc. from the first access node such as the first router etc.This process is commonly called changes hand.As a part of changing hand, the CoA of MN (Care-of Address)/CCoA (co-located care-of address) need to be updated and use the MIP signaling to be delivered among the HA subsequently, so that grouping is redirected to this MN via this new couple in router.As a part of changing the hand process, need to the first couple in router change in the corresponding state information of MN related in the hand with this at least some pass to this new couple in router so that the MN service is not interrupted.This process is called state transfer.State transfer can comprise that for example before former is to deliver to the transmission of this MN access session in the AAA overview state information of that AR (couple in router) of its place's beginning via RADIUS.It also can comprise airlink security vectors for example, MN-NAI, MN IP address, MN-EUI-64, MIP registration residue lifetime, the qualification of MN multicast group members, access control state, resource reservation state, differentiated services state, SIP session status, compressor state, MN schedule history and/or because of the transmission of many other potential possible items of the different AR state information of MN.
In at least a known system, the transmission of state information is to send state transfer message by communication network to the original old access node that connects of this mobile node by the new access node that mobile node is connecting to reach during a handoff.In response to this, old access node is transmitted to new access node with state information.Alternatively, store the state that is associated with given mobile node with core node.When described mobile node attempted to shift to another target access node, described target access node can be retrieved the state that is associated with described mobile node from described core node.
Be also referred to as MIPv4[MIPv4] and MIPv6[MIPv6] Mobile IP (edition 4 and 6) so that mobile node (MN) can be registered it by the temporary position of Care-of Address (CoA) indication to its home agent (HA).Subsequently, the mapping (being also referred to as binding) between the CoA that HA keeps the permanent address of this MN---being also referred to as in addition home address (HoA)---and register is so that can use IP encapsulation technology (tunnelling) to be redirected to its current location for the grouping of this MN.When using MIPv4, the employed CoA of MN can be the address that belongs to Foreign Agent (FA) in the couple in router, perhaps it can be the address of temporarily distributing to this MN oneself from the couple in router prefix, and it is called as co-located care-of address (CCoA) in this case.A rear model also can be applicable to MIPv4, although it is unique mode of operation in MIPv6.Attention: with regard to the purpose of the literature, term CCoA and CoA and registration and Binding Update (BU) are interchangeable, because they are corresponding terms of MIPv4 and MIPv6.
