Method and system for controlling user terminal to read system message

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...

AI Technical Summary

Problems solved by technology

[0010] The present invention provides a method for controlling a user terminal 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 active state, and overcomes the general inability of an active UE in the prior art The normal reception of system messages causes the UE to respond untimely
