Embodiment Construction

[0041] The present invention provides a method for controlling user terminals to read system messages, which is applied to read changed system messages when a UE adopting OFDM technology in an LTE system is in an activated state, and the method includes:

[0042] When the system information changes, the network side sends an indication message to the user terminal in the activated state, and the indication message carries the scheduling information of the changed system information; after receiving the indication message, the user terminal reads the changed information according to the scheduling information. following system messages.

[0043] Fig. 1 is a schematic diagram of the signaling flow of the method of the present invention, including:

[0044] 1. The network side entity (such as a radio resource control RRC entity) determines whether the system message has changed, and when the system message changes, generates an indication message carrying the scheduling informati...

Abstract

The disclosed method for controlling terminal reading system message comprises: when the system message changes, the NS sends indication including the changed scheduling message to the activated terminal; the terminal receives the indication message to read the latest system message. This invention enables the UE activated by OFDM technology to obtain system message in a LTE system normally, and improves system access performance.

Description

technical field [0001] The present invention relates to a long-term evolution (long-term evolution, LTE) system, and in particular to a method and system for controlling user terminals using Orthogonal Frequency Division Multiplexing (OFDM) technology to read system messages. Background technique [0002] System messages include: user terminal (UE) timers and counters, public land mobile network (PublicLand Mobile Network; PLMN) identifier (ID), registration area ID, parameters required for cell selection and reselection; cell ID , common channel configuration information, measurement control messages, and so on. [0003] In the prior art, system information is sent through a broadcast channel (Broadcast Channel, BCH) in the form of a Main Information Block (Main Information Block, MIB) and a system information block (System Information Block, SIB). Since the BCH is intended to be received by UEs in the entire cell, it adopts a fixed lower rate and a fixed transmission form...
