System information managing method and device in LTE (Long Term Evolution) system

Abstract

The invention provides a system information managing method and a device in an LTE (Long Term Evolution) system. The system information managing device comprises a message transceiver, a message constructing analyzer, a system information managing processor, a system information managing controller, a system message transceiving controller, a data manager and a timer manager, and a system information message processor, wherein the message transceiver is used for receiving system messages; the message constructing analyzer is used for analyzing system information, and the system information is provided for the system information managing processor; the system information managing controller is used for triggering the system information transceiving controller and initializing the data manager and the timer manager; the timer manager is used for managing the system information receiving controller and the data manager; the data manager is used for managing the saving, the modification and the deletion of the system information and the content and the state of common control information; the system information transceiving controller is used for acquiring the frame number and the subframe number of the current system and carries out receiving judgement according to the scheduling information of the system information to control a physical layer so as to monitor the transmission channel of the system information and receive the system information; and the system information message processor is used for carrying out corresponding processing on the received different system information according to the types of the system messages.

Description

Technical field [0001] The present invention relates to the field of mobile communication technology. Specifically, the present invention relates to a system information management method and device in an LTE system. Background technique [0002] The Long Term Evolution (LTE) system is the long-term evolution plan of the third generation mobile communication system (3G). The International Organization for Standardization 3GPP launched the research and development work of the LTE project at the end of 2004. At present, its standard system has reached a comparatively high level. At the mature stage, the 3GPP organization has publicly released the first version of the technical standards for LTE in March 2009. [0003] The goal of LTE is to build a wireless access system with high data rate, low latency and full packet. The main performance indicators of the LTE project include: providing a peak rate of 100Mbps in downlink and 50Mbps in uplink in a 20MHz spectrum bandwidth; improving...

AI Technical Summary

Problems solved by technology

The LTE standard clearly defines system information scheduling information, the content of each system information, and explains the handling of special situations that may occur during the system information management process. However, how to achieve fast and efficient reception of system information and timely system information processing, And feedback reception control according to the processing results, thereby affecting the reception and processing of subsequent system information, neither the LTE standard nor the existing technology provides such an implementation technology
