Using mobile messaging service message(s) as bearer for location related communications during voice call

摘要

In a mobile communication network that does not support simultaneous data communication during an active voice call of a mobile station, location information of the mobile station is obtained from a positioning server on the mobile communication network using mobile messaging service type messages as a transport bearer between the mobile station and the mobile communication network. A mobile messaging service message from the mobile station includes information regarding one or more nearby WiFi access points and/or cellular base stations detected by the mobile station. The location of the mobile station is determined by the positioning server, and the results are sent to the mobile station via a responsive mobile messaging service message including the determined location, during the active voice call, for use by an application program running on the mobile station.

1. A mobile station comprising:
a wireless transceiver for performing a wireless mobile communication voice call through a mobile communication network during which simultaneous voice and data communications are not supported and simultaneous voice communications and mobile messaging service type messages are supported; at least one audio user interface device, configured to receive audio input and to output audio during a voice call of the mobile station through the mobile communication network via the wireless transceiver; a processor coupled to the wireless transceiver and the at least one audio user interface device; a memory accessible by the processor; an application program in the memory for the processor, wherein execution of the application program by the processor configures the mobile station to perform at least one function based on location information of the mobile station; and programming in the memory for the processor, wherein execution of the programming by the processor configures the mobile station to perform functions, including functions to: in response to a query for the location information of the mobile station by the application program, during the voice call, resulting from execution of the application program during the voice call, generate an initial request for the location information of the mobile station, the request including information obtained from the air by wireless reception of radio frequency signals by the mobile station; cause the wireless transceiver, in response to the generated initial request for location information of the mobile station, to transmit the generated initial request as a mobile messaging service type message through the mobile communication network during the voice call to a messaging service server; receive a responsive mobile messaging service type message through the mobile communication network during the voice call, the responsive mobile messaging service type message including the initially requested location information of the mobile station and including error radius information; and in response to the responsive mobile messaging service type message including the requested location information, process the received location information of the mobile station for further execution of the application program.
