Abstract

The embodiment of the invention provides a notifying and reading method and device of the update of a system broadcast message, relates to the field of communication, and can solve the problem of the influence of the change of the system broadcast message associated to an MTC (Multimedia Telephone Communication) device to a non-MTC device. The reading method of the updated system broadcast message includes receiving a paging message and/or a system information change instruction message which include instruction information of the update of system information related to the MTC device about the system broadcast message; and reading a broadcast control channel to obtain the updated system information related to the MTC device in the system broadcast message according to the instruction of the instruction message when a user device is judged to be the MTC device.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for notifying and reading system broadcast message updates. Background technique [0002] In the prior art, after the UE (User Equipment, user equipment) is turned on, it will select a cell with good signal quality to camp on, and then continuously perform cell reselection to select a best cell to camp on. An important feature of cell residency is to read the information on the system broadcast message (Broadcast Control Channel, broadcast control channel) of this cell to obtain the public configuration information of this cell, such as public channel configuration information, access information, and neighbor cell list and other information. [0003] The information sent on the system broadcast message is called system broadcast information, and is broadcast periodically to inform the UE of the specific situation of the network in real time. The content of the syst...
