Method for interconnecting and intercommunicating identity and location separating network and traditional network, identity location register (ILR) and access service router (ASR)

Abstract

The invention provides a method for interconnecting and intercommunicating an identity and location separating network and a traditional network. The method comprises the step of building mapping entries including a router location marker of an intercommunicating service router (ISR) and traditional network routing information through an identity location register (ILR). The invention further provides an identity location register, wherein the identity location register (ILR) comprises a mapping relation building module. The mapping relation building module is used for building the mapping entries including the router location marker of the ISR and the traditional network routing information. The invention further provides an access service router. The interconnection and the intercommunication of the identity and location separating network and the traditional network are achieved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for interworking between an identity and location separation network and a traditional network, an Access Service Router (ASR for short) and an Identifier Locator Register (ILR for short). Background technique [0002] In the TCP / IP (Transmission Control Protocol / Internet Protocol, Transmission Control Protocol / Internet Protocol) protocol widely used in the existing Internet, the IP address has dual functions. , which is also used as the identity of the network interface of the transport layer host. The TCP / IP protocol did not consider the movement of the host at the beginning of its design. 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 host changes, not only the route changes, but also the identity of the communication terminal host ch...

[0015] However, in actual network deployment, the identity and location separation network usually communicates with multiple traditional networks, such as figure 2 As shown, that is to say, there will be multiple ISRs in the identity and location separation network. Therefore, when the ASR receives the message from the terminal, it judges that the destination address is not within the range of the identity and location separation network AID, and it cannot simply follow the configuration. Determine which ISR should be sent to
