The MTC terminal may send the power saving indication information to the base station by using the RRC signaling, or may send the power saving indication information to the MME by using the NAS signaling. If the power saving indication information is sent to the MME through the NAS signaling, the paging cycle control information configured by the MME is forwarded to the MTC terminal by the base station. If the power saving indication information is sent to the base station through RRC signaling, the base station needs to negotiate with the core network to configure paging cycle control information, and the core network also stores the paging cycle control information, which is used when paging the MTC terminal.

In addition, the MTC terminal may send the power saving indication information to the network node, and may also send the time length information in the power saving state to the network node.

Under normal circumstances, the smart meter reports the value to the power company once a week, and does not need to communicate with the power company for the rest of the time. Referring to FIG. 3, the trigger control method using the smart meter as an example includes the following steps:

Step 301: After the smart meter reports the value to the power company, the application layer of the smart meter determines that the smart meter does not need to communicate with the power company for a long period of time, and notifies the access layer to perform the power saving state.

Step 302: The access layer sends the indication information of entering the power saving state to the network side by using the air interface signaling.

Step 303: The network side configures new paging cycle control information for the smart meter, wherein the paging cycle length is 10 SFN cycle lengths, and the paging location is a location of the 5th SFN cycle 200 ms.

Step 305: The smart meter in the power-saving state monitors the paging channel at a position of 200 ms in the 5th SFN period in 10 SFN periods.

Here, the network side may send a paging message in multiple SFN periods, for example, in 10 SFNs, in order to prevent the initial SFN period from being inconsistent with the understanding of the smart meter, when communicating with the smart meter that needs to be in the power saving state. A paging message is sent at a position of 200 ms in the 4th, 5th, and 6th SFN periods in the cycle.

Step 306: The smart meter in the power-saving state enters the connection state when the paging message is monitored.
