Therefore, the address of the MME selected by the MME is also stored on the base station device, and the base station device can obtain the MME selected according to the identifier query carried in the message sent by the MME to the base station device. The address of the MME. The address of the MME that is selected by the MME may include: an address of the board that is continuously running in the specified time period or that is lower than the preset threshold, and may be continuously running within a specified time period. The address of the logical unit carrying the board function on the MME, or the load level is lower than the preset threshold.

Information about the terminal device. And storing, in the base station device, information of the terminal device served by the base station device according to the newly established S1 connection of the selected MME.

The method for managing the network provided by the embodiment of the present invention can be used by the MME to automatically determine the appropriate board according to the load status and the running status of the board, and send the determined address of the board to the base station, so that the base station device and the MME can Establish a connection with the address of the newly determined board, This completes the process of switching a board with a higher load to a board with a lower load. In the prior art, the board load of the MME is also monitored and adjusted by the operator, but the problem of the board load of the MME is often caused by the problem that the adjustment result is not timely or due to the operator's experience. It cannot be effectively solved. Therefore, in the prior art, when the board is overloaded, this affects the stability of the wireless network system and reduces the operating efficiency of the wireless network system.
