Embodiment Construction

[0034] The key of the present invention lies in the distributed management of terminal identities, that is, a part of terminal identities are managed and controlled by the relay. When users within the coverage of the relay initiate random access, the relay assigns the terminal identities to the users.

[0035] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Reference image 3 , The terminal identification allocation method of the embodiment of the present invention mainly includes the following steps:

[0037] Step 301: The base station allocates multiple terminal identifiers to the relay device from the terminal identifier resource pool maintained by itself;

[0038] Step 302: After receiving the user's access request, the relay device selects one of the multiple terminal identifiers and assigns it...

Abstract

The invention provides a terminal identifier distribution method and a communication system. The method comprises the following steps that: A, a base station distributes a plurality of terminal identifiers from a self maintained terminal identifier resource pool to trunk equipment; and B, after receiving access request of a user, the trunk equipment selects one of the plurality of terminal identifiers and distributes the terminal identifier to the user. Because of the trunk managed and distributed terminal identifier, the access time delay of the user can be effectively shortened, and the signaling interaction expense can be reduced.

Description

Technical field [0001] The present invention relates to the field of communication, and in particular to a method for assigning terminal identification in a relay-based cellular network communication system. Background technique [0002] In existing network systems based on shared channels, such as Long Term Evolution (LTE) and High Speed ​​Packet Access (HSPA), multiple users share service channel resources. At a certain moment, which user uses the resource is controlled by the channel. The carried terminal identification indicates. In a cell, among the users being served, different users are assigned different terminal identities, so that there is no ambiguity when scheduling users. In the LTE system, this identifier is called the Cell Radio Network Temporary Identifier (C-RNTI), and is allocated during the user's application for access to the system, that is, the random access process. [0003] See figure 1 , The random access process of the existing LTE system mainly includes...
