Embodiment 1

[0119] Embodiment 1: About the system information content in the LTE-LAN ​​system.

[0120] In the embodiment of the present invention, it is stipulated that the system information in the LTE-LAN ​​system may include: MIB and SIB, where:

[0121] The contents of the MIB include: cell downlink bandwidth, PHICH configuration and SFN.

[0122] The content of the SIB includes: PLMN ID, TAC, cell ID, whether the cell is allowed to access, terminal maximum uplink transmit power, uplink bandwidth, uplink frequency, TDD subframe configuration information, other SIB scheduling information (that is, other types of SIB Transmission radio frame period (transmission period), subframe position and repetition period, etc.); access control related information (ie, whether to allow call type access such as calling or called, same as LTE system), public configuration of radio resources information, the name and timing duration of the timer in the connection establishment process, the name and ...

Embodiment 2

[0126] Embodiment 2: Regarding the transmission mechanism of system information in LTE-LAN.

[0127] In the embodiment of the present invention, the system information in the LTE-LAN ​​is transmitted in a semi-static configuration mode, specifically as follows:

[0128] The transmission mode of MIB and SIB1 is the same as that of LTE existing technology;

[0129] Other types of SIBs also use transmission methods similar to MIB and SIB1. The transmission configuration parameters of other types of SIBs, including the radio frame period of transmission (ie transmission period), subframe position and repetition period, can be broadcast to UE through SIB1, or It is pre-specified by the protocol, that is, the transmission configuration parameters of other types of SIBs are pre-agreed between the network side and the UE side.

[0130] Among them, the transmission configuration parameters of other types of SIBs, for example:

[0131] The wireless frame period can be 160ms, 320ms, 64...

Embodiment 3

[0138] Embodiment 3: About the system information update mechanism in LTE-LAN.

[0139] When the system information changes, the network side (specifically, it can be the AP) notifies the UE through RRC dedicated signaling, and the signaling can be an RRC connection reconfiguration message, or other newly defined messages. In this message, only one identifier is used to notify the UE whether the system information of the current cell is changed. The identifier may be a bit (bit). For example, when the bit is 1, it indicates that the system information is changed.

[0140] Alternatively, a newly defined message is used, and the content of the message is empty. As long as the UE receives the message, it considers that the system information has changed.

[0141] After the UE determines that the system information is changed, the UE re-reads the system information of the current cell from the next modification period.

Abstract

The invention discloses a method and a system which are used for transmitting system information and applicable to an LTE-LAN (Long Term Evolution-Local Area Network) system, and achieve more simple and feasible transmission of the system information and an improvement in the transmission efficiency of the system information. The method comprises the steps as follows: determining transmission configuration parameters of a master information block (MIB) of the system and various types of system information blocks (SIB); and according to a semi-static configuration manner and the transmission configuration parameters of the MIB, sending the MIB, and sending the various types of the SIBs according to the transmission configuration parameters of each type of the SIBs.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for transmitting system information. Background technique [0002] In order to meet the increasing demands of users for data services, a wireless network access system based on the Long Term Evolution (LTE, Long Term Evolution) system - the Long Term Evolution Local Area Network (LTE-LAN, Long Term Evolution Local Area Network) system, should be implemented And born. The LTE-LAN ​​system constructs a local wireless network, and an access point (AP, Access Point) device of the LTE-LAN ​​system provides network coverage and wireless access services for users. Since the LTE-LAN ​​system adopts a flat network architecture, it can realize user equipment (UE, User Equipment) access to external networks simply and at low cost. [0003] The existing LTE-LAN ​​is divided into two network architectures: a public LTE-LAN ​​network and a private LTE-LAN ​...
