Embodiment Construction

[0069] Such as figure 1 As shown, the bearer network architecture of the present invention includes: a terminal device, an access switch router, a mapping server and multiple bearer network planes, wherein:

[0070] Terminal equipment uses UID (User Identity, identity identifier) ​​as the addressing identifier for registration and communication. It is the unique identifier of terminal equipment identity. It is used at the access layer. This is a fixed allocation that remains unchanged when the equipment moves. The UID of the device uses binary representation, and the length is greater than 32 bits, that is, the space of the identity UID is greater than 2 to the 32nd power; the message sent and received by the terminal device is compatible with the traditional IP message format.

[0071] Specifically, the identity UID of the terminal device is divided into two parts, the low segment UID_L and the high segment UID_H, the lower 32 bits (binary) are the lower segment, and the mess...

Abstract

The invention discloses a carrying network which comprises a plurality of carrying network planes and terminal devices, wherein the carrying network planes form an Internet protocol (IP) carrying network so as to realize routing and forwarding of data messages among the terminal devices, each carrying network plane in the plurality of the carrying network planes is configured with an exclusive serial number, and an independent routing address space is adopted for routing and addressing; and each terminal device adopts a user identifier (UID) as an addressing marker, each UID comprises low level (UID-L) and high level (UID-H), the low level adopts an IP address space, and the high level is used for increasing the number of bits of the UID and extending the address space. The problem that IP addresses are insufficient can be solved through a multi-plane carrying network architecture and the user identifiers of the terminals devices, which are greater than 32 bits, and the solution of separating terminal identifies from the positions can be simultaneously realized through the multi-plane structure, so that the two problems can be effectively solved.

Description

technical field [0001] The invention relates to the field of data communication and Internet technology, in particular to a bearer network and a terminal communication method. Background technique [0002] The research on the next-generation information network architecture is one of the current hot research topics. The basic direction of this research topic is the telecommunication network represented by the voice service, the TV network represented by the video service, and the Internet represented by the data service. For the purpose of seamless business integration, it is characterized by IP-based network bearer. Typical examples include VOIP networks that provide voice services, IPTV networks that provide TV services, 3G mobile communication networks that are carried by IP core networks, and a large number of ultra- 3G or 4G network research projects, etc. [0003] 4G is the abbreviation of the 4th generation mobile communication system. The goal of 4G is to provide an...
