ABSTRACT:
The invention provides a communication apparatus switching method. At first, the method of the invention measures at least one environmental parameter relative to a neighboring region of a mobile communication apparatus and then determines whether the mobile communication apparatus is indoors, based on the at least one environmental parameter. If YES, the following steps are executed. Firstly, the method establishes a wireless communication link between the mobile communication apparatus and an agent communication apparatus based on a wireless communication protocol. Then, the method sends a piece of user information to the agent communication apparatus. Afterward, the method terminates a first radio telecommunication link between the mobile communication apparatus and the base station. Finally, the method establishes a second radio telecommunication link between the agent communication apparatus and the base station based on a radio telecommunication protocol.
