Abstract
A method is provided for updating a position of a mobile device coupled to a wireless communication network via one of a plurality of base stations. The method comprising the following steps. A position of the mobile device is determined. The mobile device then waits for a predefined trigger notification before determining an updated position of the mobile device. The predefined trigger notification is generated in response to a motion trigger. A device configured to implement the method as well as a computer readable medium comprising instructions to implement the method are also provided.
Claims19
A method for updating a position of a mobile device coupled to a wireless communication network via one of a plurality of base stations, the method comprising:
- determining a position of the mobile device;
- and
- waiting for a predefined trigger notification before determining an updated position of the mobile device, the predefined trigger notification being generated in response to either a motion trigger or a time trigger, the time trigger being reset upon detection of the motion trigger, the time trigger comprising expiration of a polling time period, the polling time period determinative of a polling frequency, the polling frequency being reduced when the mobile device is determined to be stationary.
A mobile device coupled to a wireless communication network via one of a plurality of base stations, the mobile device comprising:
- a positioning device configured to retrieve a position of the mobile device;
- and
- a microprocessor configured to enable the positioning device to retrieve the position in response to a predefined trigger notification, the predefined trigger notification being generated in response to either a motion trigger or a time trigger, the time trigger being reset upon detection of the motion trigger, the time trigger comprising expiration of a polling time period, the polling time period determinative of a polling frequency, the polling frequency being reduced when the mobile device is determined to be stationary.
A computer readable medium comprising instructions which, when executed on a mobile device coupled to a wireless communication network via one of a plurality of base stations, cause the mobile device to:
- determine a position of the mobile device;
- and
- wait for a predefined trigger notification before determining an updated position of the mobile device, the predefined trigger notification being generated in response to either a motion trigger or a time trigger, the time trigger being reset upon detection of the motion trigger, wherein the time trigger comprising expiration of a polling time period, the polling time period determinative of a polling frequency, the polling frequency being reduced when the mobile device is determined to be stationary.
