Problems solved by technology

This method of terminal identifier allocation requires two interactions between the relay and the base station, which not only increases the overhead of signaling interaction, but also prolongs the response time to the terminal, thus affecting user experience

Embodiment Construction

[0034] The key of the present invention is to perform distributed management on the terminal identification, that is, the relay manages and controls a part of the terminal identification, and when the user within the coverage of the relay initiates random access, the relay assigns the terminal identification to the user.

[0035] In order to make the object, technical solution 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] refer to image 3 , the method for allocating terminal identifiers in the embodiment of the present invention mainly includes the following steps:

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

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

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 invention relates to the communication field, in particular to a method for allocating terminal identifiers 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 traffic channel resources. The carried terminal ID indicates. In a cellular cell, different users are assigned different terminal identities among the users being served, so that there is no ambiguity in scheduling users. In the LTE system, this identifier is called a Cell Radio Network Temporary Identity (C-RNTI), and is allocated during the process of a user applying 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 the following steps: [0004] Step 101: the terminal sends a random access preamble (prea...
