Embodiment Construction

[0027] The ubiquitous network described in the present invention conforms to the design concept of the active network. The so-called active network is a new network structure that allows users to program intermediate nodes of the network (such as routers, switches, etc.). Active network nodes are sensitive to applications and can provide different services for different applications, such as finding the best path according to the network channel status, activating different processing according to different messages, allowing users to create their own services and distribute them to the network on demand. The concept of active network design is proposed for the shortcomings of the network architecture based on the TCP / IP protocol. To realize this concept, it is necessary to fundamentally change the architecture of the existing network. Therefore, there are many obstacles in the implementation.

[0028] The present invention advocates the design concept of using a virtual netwo...

Abstract

The invention relates to a virtual reconstruction heterogeneous integrated ubiquitous network system architecture, which consists of a terminal extending layer, a network access layer, a virtual reconstruction layer and an application layer, wherein the terminal extending layer comprises a terminal directly accessing the network layer and a tail network indirectly accessing the network layer through the terminal; the network access layer comprises an access network and a core network; the virtual reconstruction layer realizes integration of multiple heterogeneous networks and supports control interaction and data interaction between heterogeneous network equipment; the application layer consists of service middleware and an application server; and a requirement is supplied to the virtual reconstruction layer, and the virtual reconstruction layer is used. By the system architecture, the resource utilization rate and the system robustness are improved; and more ways and more modes are supplied to expanding the upper layer application.

Description

technical field [0001] The invention belongs to the technical field of wireless communication networks, in particular to a virtual reconstructed ubiquitous network architecture of heterogeneous fusion. Background technique [0002] It is generally believed that the next-generation network is based on IP, supports multiple services, can realize the separation of services and transmission, independent control functions, open interfaces, a packet network with quality of service (QoS) guarantee and support for general mobility. [0003] Ubiquitous communication aims to realize smooth communication with anyone and anything at any time, any place, and is an important requirement of the next generation network. Therefore, in a sense, the next-generation network can also be called a "ubiquitous network", that is, a network that exists widely, and its basic characteristics are ubiquitous, all-encompassing, and omnipotent. [0004] In the past ten years, with the development of infor...
