Embodiment Construction

[0028] In order to make the technical solutions and advantages of the present invention clearer, the system information management device and method in an LTE system of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] In the LTE system, the system information is broadcasted by the base station to the user terminal, which is necessary information for the terminal to access the system. The broadcasted system information includes some system-level parameter information related to the network part and the entire communication system: such as non-access stratum (NAS, NonAccess Stratum) general information, information applied to user equipment in a non-connected state (such as ) selection parameters), neighboring cell information, and information used for wireless user terminal equipment in a radio resource control connection state (such as general channel configuration information), earthquake and tsunam...

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