COLLECTIVE POSITIONING IN MOBILE COMMUNICATION SYSTEMS |
摘要 |
Methods and devices for managing a cellular communication system (1) and mobile terminals (40) are presented. A collective positioning measurement order (50) is issued to a multitude of mobile terminals (40) in a first cell (10) of the cellular communication system (1). This issuing is preferably performed intermittently at a multitude of times according to a predetermined rule. Each mobile terminal (40) receives information concerning a collective positioning measurement order. The mobile terminal (40) performs a positioning operation, typically a positioning measurement on a ranging signal (51, 52) or transmission of a ranging signal (53), preferably intermittently at a multitude of times, according to a predetermined rule based on the information concerning the collective positioning measurement order. An updating of a storage with positioning data can preferably be obtained. In terrestrially based positioning systems, signal resources dedicated to positioning measurement can be reserved in the cellular communication system. |
