Problems solved by technology

[0006] 1) Regardless of which ISR or ASR the data of the mobile terminal passes through, the ASR of the message sender must synchronize the correspondence between the AID and RID of the mobile terminal and the change message to all ISRs and other ASRs in the identification network, which will cause Waste of ISR and ASR resources and unnecessary performance loss;
[0007] 2) When the sender's ASR does not synchronize the correspondence between AID and RID to the ISR or other ASRs in the identification network fast enough, or the ISR or other ASRs do not process

application example 1

[0104] like image 3 shown, including the following steps:

[0105] Step A, the mobile terminal accesses the public network (the identity of the MN is AID1), and sends a message whose destination address is a public network address;

[0106] Step B, the message sent by the mobile terminal arrives at ISR1 through ASR1 (the location identifier of ASR1 is RID1), and the message carries the correspondence between the identity identifier AID1 and the location identifier RID1 of the mobile terminal;

[0107] Step C: After receiving the message, ISR1 uses the AID1 and RID1 carried in the message to look up the correspondence table between AID and RID. If it is not found, it means that it is the first packet of the mobile terminal to go online. The relationship is sent to the control plane, and step E is executed;

[0108] Step D, if the RID information corresponding to AID1 is found on ISR1, compare the RID1 carried in the message with the RID in the entry, if the two are consisten...

application example 2

[0113] like Figure 4 shown, including the following steps:

[0114]Step A, mobile terminal 1 (identity mark of MN1 is AID1) visits mobile terminal 2 (identity mark of MN2 is AID2), promptly sends the message that destination address is the address of mobile terminal 2;

[0115] Step B, the message sent by mobile terminal 1 arrives at ASR2 through ASR1 (the location identifier of ASR1 is RID1), and the message carries the identity identifier AID1 and location identifier RID1 of mobile terminal 1;

[0116] Step C, after ASR2 receives the message, use the corresponding relationship between AID1 and RID1 carried in the message to search the local AID and RID correspondence table, if it is not found, it means that it is the first packet of the mobile terminal 1 to go online, Then send the corresponding relationship between AID1 and RID1 to the control plane, and execute step E;

[0117] Step D, if ASR2 finds the RID information corresponding to AID1 locally, compare the RID1 car...

Abstract

The invention discloses a method for learning a corresponding relationship of an AID (access identifier) and an RID (routing-location identifier), an ASR (access service router) and an ISR (interworking service router). The method is applied in the ISR and comprises the following steps after a message sent by the ASR is received, searching whether corresponding relationship of the AID and the RID carried in the message is locally stored; and if no, updating the corresponding relation of the AID and the RID carried in the message to the local. The method is applied in the ASR and comprises the following steps that after the message sent by the other ASR in the identification network is received, searching whether the corresponding relationship of the AID and the RID carried in the message is locally stored; and if no, updating the corresponding relationship of the AID and the RID carried in the message to the local. After the invention is adopted, the storage resource of the ISR or the ASR can be saved; the flow abandoning is avoided; the system resource is saved; and the processing speed of the message is accelerated.

Description

technical field [0001] The present invention relates to identification network technology, in particular to a method for learning the corresponding relationship between AID (Access Identifier, user identity identifier) ​​and RID (Routing-Location Identifier, routing location identifier), ASR (Access Service Router, access service router) And ISR (Interworking Service Router, Interworking Service Router). Background technique [0002] The IP address in the TCP / IP protocol (Transmission Control Protocol / Internet Protocol, Transmission Control Protocol / Internet Protocol), which is widely used in the Internet, has dual functions. , which is also used as the identity of the network interface of the transport layer host. At the beginning of the TCP / IP protocol design, the movement of the host was not considered. However, when the host mobile becomes more and more common, the semantic overload defect of this IP address becomes more and more obvious. When the IP address of the ho...
