Abstract: An electronic communications terminal records in a memory a sampled audio segment of sound sensed by a micro-phone. A time stamp associated with timing of the recording of the sampled audio segment is determined and stored in the memory associated with the sampled audio segment. The sampled audio segment and the time stamp are transmitted through a network interface toward a location service client of a network node that determines location of the electronic communications terminal based on correlating the sampled audio segment and other sampled audio segments of the sound received from other electronic communications terminals. A related network node and corresponding methods by terminals and network nodes are disclosed.

Abstract: The present invention relates to a communication device and to a method arranged to execute at least one positioning function in a communication network. According to the present invention, a positioning function execution time is determined, at which a transmission medium will be used for executing position transmissions, according to a positioning function execution time information. Further, the at least one positioning function is executed at the determined positioning function execution time by executing the at least one positioning function transmission via the transmission medium. The present invention relates also to a correspondingly arranged computer program product and to a correspondingly arranged computer-readable recording medium.
