Location based service (lbs) enhanced by short-range wireless communication

A server, comprising:

• a processor;
• a memory storing instructions which, when executed by the processor, cause the processor to perform operations comprising:
• select, from one or more terminal devices, at least one second terminal device based on at least first information reported by the first terminal device and/or second information reported by the at least one second terminal device, the first information indicating a second identifier of the at least one second terminal device received by the first terminal device via short-range wireless communication, the second information indicating a first identifier of the first terminal device received by the at least one second terminal device via short-range wireless communication;
• and
• determine a location of the first terminal device based on at least a location of the at least one second terminal device.

A method at a first terminal device for facilitating a server in locating the first terminal device, the method comprising:

• detecting whether there is a short-range wireless signal from a second terminal device;
• receiving, from the second terminal device, a second identifier of the second terminal device in response to detecting that there is a short-range wireless signal from the second terminal device;
• and
• reporting, to the server, information indicating the second identifier of the second terminal device.
