Embodiment Construction

[0098] The present invention will be described in more detail below in conjunction with the accompanying drawings and embodiments.

[0099] The core idea of ​​the identity and location separation architecture is: divide the network into the access layer and the core layer, assign a unique user identity to each user in the network, and the user identity remains unchanged during the mobile process; the network There are two types of identifiers: user identity identifier (Access Identifier, AID for short) and location identifier (Routing-Location Identifier, RID for short). Among them, AID is a unique identity assigned to each user in the network. It can only be used at the access layer and remains unchanged during the movement of the user terminal. The AID is used between user terminals to identify the opposite end. The AID of the opposite end needs to be used for communication; the RID is a location identifier allocated for the user terminal and can only be used at the core lay...

Abstract

A method and system are provided for initiating forwarding of communicaiton, information and data message. The method for initiating communication by a terminal includes: the terminal sends a data message to the Access Service Node ( ASN ) to which the terminal belongs, the data message includes an Access Identifier(AID) of a communicaiton opposite end; after the ASN to which the terminal belongs receives the data message, if the Routing-Location Identifier(RID) corresponding to the AID of the communication opposite end is unable to be searched out locally, the data message will be sent to a mapping forwarding plane; when the mapping forwarding plane receives the data message, it queries the RID corresponding to the AID of the communication opposite end and encapsulates it in the data message, and then the data message is forwarded to the ASN to which the communication opposite end belongs through a generalized forwarding plane; when the ASN which the communication opposite end belongs to receives the data message, it divests the data message of the RID and sends the RID to the communication opposite end. A routing configuration method is provided in the network in which the AID and RID are separated, a mapping plane is divided into multi-domains, and routing information is established, saved and maintained for each intra-domain node and inter-domain node.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method / system for initiating communication, forwarding of information / data messages and routing configuration under the framework of separation of identity mark and location. Background technique [0002] The IP address in the TCP / IP (Transmission Control Protocol / Internet Protocol, Transmission Control Protocol / Internet Protocol) protocol widely used in the existing Internet has dual functions. It 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 changes, which will lead to a...
