Description
Technical Field
The present invention relates to the field of MTC communication technologies, and in particular, to a method, an apparatus, and a system for processing system message changes of an MTC terminal in a connected state.

MTC communication refers to a communication manner between machines (device to device) without human involvement, and is also called M2M (Machine-to-Machine) communication.
In order to deal with MTC communication, 3GPP has optimized LTE protocol itself to different degrees, and unlike LTE System Information including MIB (Master Information Block) and multiple SIBs (System Information blocks), 3GPP rel.13 standard introduces new System messages MTC-SIB1, MTC-SIB2, MTC-SIB3, MTC-SIB4, MTC-SIB5, and MTC-SIB14 to replace SIBs, that is, System Information related to MTC communication includes: MIB and MTC-SIB1, MTC-SIB2, MTC-SIB3, MTC-SIB4, MTC-SIB5 and MTC-SIB14, and it is specified that an MTC terminal in an RRC (Radio Resource Control) connection state does not need to monitor all system messages, but only needs to monitor three system messages, namely MIB, MTC-SIB1 and MTC-SIB 2. When the three monitored system messages change, if the NW (Network) needs to trigger the MTC terminal to reacquire the system messages, the system message acquisition procedure may be triggered by the RRC connection release message, and the MTC terminal returns to an idle state after receiving the RRC connection release message, performs cell selection first, and then reacquires all the system messages.
In the process of implementing the invention, the inventor finds that at least the following technical problems exist in the prior art:
when the MTC terminal in the connected state needs to reacquire the system message due to a change in the monitored system message, it is necessary to perform cell selection each time and then reacquire all the system messages, which may cause large power consumption in the MTC terminal.
