Remote method for wireless transmission of location data
First Claim
1. A remote method of determining a geographic location of a wireless mobile unit capable of communicating with a wireless telecommunications network, the method comprising the steps of:
- at the mobile unit, receiving a location query via a wireless telecommunications network serving the mobile unit;
responsive to the location query, downloading location data from a GPS unit coupled to the mobile unit; and
transmitting the location data via said wireless telecommunications networkwherein the mobile unit supports at least two communication modes and further comprising;
determining what wireless communication modes are currently available to the mobile unit on the network;
assessing at least one selected characteristic of each of the currently available communication modes; and
based on the assessment, determining a preferred one of the currently available communication modes communication mode to transmit the location data.

Abstract
A method to remotely determine a location of a mobile unit without intervention by a user of the mobile unit is provided. The mobile unit may receive a location query, download location data from a GPS, and transmit the location data via a wireless telecommunications network. For example, a call center may initiate a location query using a voice channel call to the mobile unit. In addition, the mobile unit may select a mode of communication from a number of alternative modes of digital wireless communication based upon a determined characteristic of the transmission mode. By way of example, the determined characteristic could be a transmission speed, cost of transmission, or signal strength of the selected communication mode. Furthermore, the unit may be a battery pack or other accessory device attachable to a wireless telephone handset.

8. A method of transmitting digital data from an accessory unit attached to a wireless communication device, the wireless communication device supporting at least two communication modes, the method comprising:
-
in the accessory unit, determining which of the communication modes of the wireless communication device are available for transmitting the digital data, by querying the attached wireless communication device; at the accessory unit, receiving a reply from the attached wireless communication device that reports on the currently available coverage for at least one wireless communication mode; storing in a memory in the accessory unit indicia of available wireless communication modes as reflected in the reply from the attached wireless communication device, and determining a characteristic of each available transmission mode; at the accessory unit, selecting one of the available transmission modes based on the determined characteristic of the transmission mode; at the accessory unit, transferring the digital data to the wireless communication device for transmission via the selected transmission mode; and at the wireless communication device, encoding the transferred digital data in a manner appropriate for the selected transmission mode and transmitting the encoded transferred digital data via the selected transmission mode. - View Dependent Claims (9, 10, 11, 12, 13)
