A method for constructing a virtual reconstructed ubiquitous network architecture based on identity and location separation

Abstract

The invention discloses a virtual reconstruction ubiquitous network architecture based on identity-position separation. The virtual reconstruction ubiquitous network architecture comprises a terminal and stub network layer, an edge access network layer, a virtual reconstitution core network layer, an application layer and a service support layer. The terminal and stub network layer comprises an intelligent multi-mode terminal supporting an identity-position separation mechanism, and a traditional terminal and stub network which has direct access to an edge access network or has access to the edge access network through a ubiquitous network gateway; the edge access network layer comprises wired and wireless access networks, provides access capability of an IP core network for a bottomlayer terminal, and achieves separation of control and bearing; the application layer comprises an application server, and provides unified service access capacity for heterogeneous users; the service support layer comprises various functional entities, and provides necessary function support. According to the virtual reconstruction ubiquitous network architecture based on identity-position separation, efficient convergence between heterogeneous networks is achieved through virtual reconstruction and identity-position separation, and support to terminal mobility and multi-connection capacity of users and terminals is achieved.

Description

technical field [0001] The invention belongs to the technical field of communication, in particular to a method for constructing a virtual reconstructed ubiquitous network architecture based on separation of identity and location. Background technique [0002] According to the definition of China Communications Standards Association, Ubiquitous Network (Ubiquitous Network) is based on the needs of individuals and society, and realizes on-demand information acquisition, information transmission, information storage, and information processing between people and people, people and things, and things and things. , with environment awareness, content awareness and intelligence, provides ubiquitous and all-encompassing information services and application networks for individuals and society. The research direction of the ubiquitous network architecture at home and abroad can be classified into two categories. One category believes that the existing network system must be overthr...
