Problems solved by technology

[0005] The inventors found that due to changes in the structure of the system message, the original update method in UTRAN cannot be fully applied in LTE, and the existing LTE-related technologies have not given a clear explanation for the update mechanism of the system message, resulting in In the current discussion plan of LTE technology, the system message update cannot be completed

Embodiment Construction

[0029] In the embodiment of the present invention, the network side sends the change information of P-BCH and / or S-BCH in the notification message, and the UE reads the changed system information according to the change information, thereby realizing the update of the system information in LTE . In one embodiment, by setting the change of S-BCH and the change of P-BCH to be independent of each other, the network side notifies the UE of which specific part changes through a notification message, so as to avoid that any change of system information will cause the UE to switch from P-BCH to P-BCH. BCH starts to read backwards, but can read the changed part directly; in another embodiment, it is also possible to set the change of S-BCH and the change of P-BCH not independent, so that any change of system message will be It is reflected in the change of P-BCH, so that the network side does not need to distinguish whether it is a change of P-BCH or a change of S-BCH when sending a n...

Abstract

The embodiment of the invention discloses a method for renewing system message, which comprises the following steps: in a long time evolution system, a piece of user equipment UE reads and saves the changed system message according to change information of the system message sent by a network side. The embodiment of the invention also discloses a network device used for renewing the system message, which comprises a communication module, a system message renewing module and a change information module. The embodiment of the invention also discloses a piece of user equipment used for renewing the system message, which comprises a communication module, an analysis module, a message renewing module and a memory. The embodiment of the invention also discloses a system for renewing the system message which comprises a base station and a UE, wherein, the base station is used for sending the change information of the system message and the changed system message, and the UE is used for receiving the change information of the system message sent by the network side and then reads and saves the changed system message according to the change information. The embodiment of the invention realizes the renewal of system message in the LTE.

Description

technical field [0001] The invention relates to a wireless message update mechanism, in particular to a system message update method, device and system. Background technique [0002] In the current Universal Terrestrial Radio Access Network (UTRAN, Universal Terrestril RadioAccess Network), the user equipment (UE) will actively receive system information when it is powered on. The system information is information about the UE's home network sent by the network side, such as UE The cell ID, public land mobile network ID and timer settings of the cell to which it belongs. The structure of the system message belongs to the main information block (MIB, Main Information Block) + scheduling block (SB, Scheduling Block) + system information block (SIB, System Information Block). Among them, the SIB is the content of the system message, and each SIB has a label. When the label changes, it indicates that the content of the corresponding SIB changes; the SB contains the scheduling i...
