Description
Technical field
The present invention relates to mobile communication field more particularly to a kind of methods of the address of acquisition strategy server.
Background technology
The existing widely used TCP/IP in internet (Transmission Control Protocol/
InternetProtocol, transmission control protocol/internet protocol) in IP address have dual function, both be used as network layer
Station location marker of the communication terminal host network interface in network topology, and as the identity mark of transport layer host network interface
Know.But when host mobility is more and more common, the semantic overload defect of this IP address is increasingly apparent.As the IP of host
When location changes, not only routing changes, and the identity of communication terminal host also changes, and will lead to road in this way
It is increasingly heavier by loading, and the variation of host identification will also lead to the interruption applied and connected.Identity and position separation
The problems such as purpose that problem proposes is the semantic overload and serious routing overhead in order to solve IP address, by the dual work(of IP address
It can be detached, realize and mobility, more local property, IP address dynamic are reassigned, mitigate routing overhead and Next Generation Internet
The support of the problems such as exchanging visit between middle heterogeneous networks region.
Fig. 1 shows that a kind of architectures of communication networks of identity and position separation configures AID in this architectures of communication networks
(Access Identifier, access mark) is used as terminal MN (Mobile Node, mobile node) and CN
The identity of (Correspondent Node, peer node).RID (RouterIdentifier, Route Distinguisher) is used as position
Mark is set, ASR (Access Service Router, access service router) is used as couple in router, configuration RID (Router
Identifier, Route Distinguisher) it is used as station location marker.All terminals are registered by ASR, certification and are accessed network and all passed through
ASR is carried out.When terminal accesses or leaves ASR, ASR is needed to ILR (Identifier＆Location Register, identity
With location register register) report.ILR preserves simultaneously maintenance terminal identity AID and position RID according to the report of ASR
Mapping relations (AID, RID), and provide simultaneously to inquire mapping relations response.
Message forwards as shown in Figure 2 in identity and location network.When MN is communicated with CN, MN is sent to the report of CN
After text reaches ASR1, whether ASR1 inquires on the local map record of ASR1 and deposits according to the destination address (i.e. the AID of CN) of message
In the current RID of CN.
If in the presence of ASR1 is packaged forwarding according to the RID of the CN inquired to message.
If being not present, ASR1 inquires the current RID of CN to ILR；ASR1 obtains the RID of CN from ILR, then uses ASR1
Message is packaged with the RID of CN, then encapsulated message is forwarded to the corresponding ASR2 of RID of CN；Last ASR2 is to reception
Message is decapsulated, and is forwarded to CN.
In message forwarding process, the encapsulation format of message is divided into two kinds of original message and RID encapsulated messages：
Original message forwards：AID conducts are used between the access layer of identity and position separated network, i.e. Host and ASR
Source address and destination address carry out message forwarding, and message format is as shown in Figure 3.
RID encapsulated messages forward：It is sealed using RID between the core layer of identity and position separated network, i.e. ASR and ASR
Message forwarding after dress, message are as shown in Figure 4.
Currently, since terminal can have multiple connections simultaneously so that the mapping relations of terminal AID and RID become complicated.
For example, in Figure 5, MN identifies net by two different interface if1 (interface1) and if2 (interface2) accesses,
Wherein if1 accesses ASR1, and if2 accesses ASR2.If1 in this way and if2 will use different station location markers, if1 to be assigned ASR1
RID1, and if2 be assigned ASR2 RID2.And in figure 6, MN is also by two different interface if1 and if2 access marks
Know net, but if1 and if2 accesses identical ASR, therefore it is assigned identical RID, the i.e. RID1 of ASR1.
Under single access technology scene, the mapping relations (AID, RID) that ILR is safeguarded can preferably complete router tasks,
But under multi-access technology scene, as described above, multiple interfaces on MN will all use identical AID, reflected at this time by what ILR was safeguarded
It penetrates relationship (AID, RID) to will be unable to distinguish the distinct interface from same MN, therefore, under multi-access technology scene, ILR is not only wanted
It safeguards (AID, RID), includes the access technology type of each interfaces of MN, to distinguish the distinct interface for belonging to same MN.Extend ILR
On mapping relations be (AID, RID, IF), by ASR complete MN on distinct interface access style ILR registration.
Under multi-access technology scene, the ILR mapping relations (AID, RID, IF) of extension have distinguished the difference for belonging to same MN
Interface, but routing is carried out by (AID, RID, IF) and is had the following problems：
Fig. 5 shows that the distinct interface of multiplex roles MN accesses different ASR, and there are two mapping relations on ILR by MN：
(AID1, RID1, IF1) and (AID1, RID2, IF2).When CN is initiated to when the communication of MN, how ASR3 selects correctly to map
Relationship route message to which interface of MN.
Fig. 6 shows that the distinct interface of multiplex roles MN accesses identical ASR, MN on ILR there are two mapping relations,
(AID1, RID1, IF1) and (AID1, RID1, IF2).When CN sends message to MN, ASR1 receives the message for coming from CN,
How ASR1 selects the interface of MN to carry out message forwarding.
Therefore, when peer node is to multi-interface terminal transmission data, opposite end ASR or terminal ASR or ILR are needed according to more
The information such as the stream routing policy of interface termination, the suitable terminal location mark of service selection initiated for peer node and interface,
To carry out normal message forwarding routing, to reduce the abnormal phenomenon of data transmission, provide the effective guarantee of data transmission.
And in ASR or ILR according to the stream routing policy information of multi-interface terminal, the service selection initiated for peer node is closed
Before suitable terminal location mark and interface, ASR or ILR must be known by the address of the strategic server where terminal, be taken from strategy
It is engaged in downloading the stream routing policy for corresponding to this terminal on device.
