Method and device for detecting neighboring cell in cell reselection process

A device applied in user equipment for detecting a neighboring cell in a cell reselection process, the device comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor;
• wherein the processor is configured to:
• receive a message instructing the user equipment to switch from a connected state to an idle state, the message including a first frequency band group which further includes one or more frequency bands;
• update a second frequency band group stored in the user equipment, according to the first frequency band group;
• and
• when the cell reselection process is performed by the user equipment, detect a neighboring cell on at least one frequency band in the updated second frequency band group.

A device for use in a base station to support user equipment detecting a neighboring cell in a cell reselection process, the device comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor;
• wherein the processor is configured to:
• detect whether user equipment satisfies a condition for switching from a connected state to an idle state;
• and
• when the user equipment satisfies the condition, send to the user equipment a message for instructing the user equipment to switch from the connected state to the idle state, the message including a frequency band group which further includes one or more frequency bands.
