Configuring a candidate serving base station for a terminal

A network device, wherein the network device is a device in an anchor base station or a mobility management server, comprising:

• at least one processor;
• and
• a memory communicably connected to the at least one processor;
• wherein
• the memory stores instructions executable by the at least one processor, wherein, the instructions, when being executed by the at least one processor, cause the at least one processor to perform the steps of:
• sending uplink signal configuration information for an idle terminal to a terminal;
• receiving, from a first base station, uplink signal measurement information and load of the first base station, wherein the uplink signal measurement information is obtained by measurement by the first base station upon receiving an uplink signal carrying a terminal identifier from the terminal based on the uplink signal configuration information, wherein the uplink signal is sent by the terminal in an idle state where no service is requested;
• and
• configuring mobility for the terminal based on the terminal identifier, the uplink signal measurement information and the load of the first base station, wherein the configuring mobility is configuring a candidate serving base station for the terminal such that the terminal initiates a service request to enter an active state at the candidate serving base station;
• wherein the configuring, by the network device, mobility for the terminal based on the terminal identifier, the uplink signal measurement information and the load of the first base station comprises:
• selecting, by the network device, the candidate serving base station based on the terminal identifier, the uplink signal measurement information and the load of the first base station, and sending a service establish request to the candidate serving base station, such that the candidate serving base station sends a service establish request response to the network device;
• and
• sending, by the network device, the service establish request response to the terminal, such that the terminal sends uplink data to the candidate serving base station based on the service establish request response.

A non-transitory computer readable storage medium, wherein the computer readable storage medium stores computer executable instructions, which, when being executed by a network device, wherein the network device is a device in an anchor base station or a mobility management server, cause the network device to perform the steps of:

• sending uplink signal configuration information for an idle terminal to a terminal;
• receiving, from a first base station, uplink signal measurement information and load of the first base station, wherein the uplink signal measurement information is obtained by measurement by the first base station upon receiving an uplink signal carrying a terminal identifier from the terminal based on the uplink signal configuration information, wherein the uplink signal is sent by the terminal in an idle state where no service is requested;
• and
• configuring mobility for the terminal based on the terminal identifier, the uplink signal measurement information and the load of the first base station, wherein the configuring mobility is configuring a candidate serving base station for the terminal such that the terminal initiates a service request to enter an active state at the candidate serving base station;
• wherein the configuring, by the network device, mobility for the terminal based on the terminal identifier, the uplink signal measurement information and the load of the first base station comprises:
• selecting, by the network device, the candidate serving base station based on the terminal identifier, the uplink signal measurement information and the load of the first base station, and sending a service establish request to the candidate serving base station, such that the candidate serving base station sends a service establish request response to the network device;
• and
• sending, by the network device, the service establish request response to the terminal, such that the terminal sends uplink data to the candidate serving base station based on the service establish request response.
