Method and system for prompting signal covered area

A system for prompting a signal coverage area, comprising:

• a positioning module, configured to:
• when detecting a signal coverage area searching instruction from a user, perform a positioning operation on a current mobile terminal, to acquire current location information of the mobile terminal;
• a blind area list information determination module, configured to:
• according to signal strength around the current location of the mobile terminal, determine a list of blind areas around the current location;
• and
• a signal coverage area indication module, configured to:
• after the user opens a map, display the current location of the mobile terminal and signal coverage areas near the current location of the mobile terminal on the map;
• wherein the system further comprises:
• a signal detection module and a blind area list information maintenance module, wherein:
• the signal detection module is configured to:
• detect received wireless signal strength;
• when the signal detection module detects that the received wireless signal strength is greater than the preset blind area signal strength threshold value, and that a distance between the current location corresponding to the current location information of the mobile terminal and location of one or more blind area boundary points recorded in the list of blind areas is less than or equal to a preset blind area distance differential threshold value, the blind area list information maintenance module deletes a record for a blind area boundary point with a distance to the current location of the mobile terminal that is less than or equal to a preset blind area distance threshold value from the list of blind areas.
