Supporting an assisted satellite based positioning
First Claim
1. A method for supporting a satellite based positioning of a mobile device using assistance data, said method comprising:
- receiving at said mobile device assistance data from a communication network including parameters of an orbit model describing a movement of a satellite of a particular satellite based positioning system;
wherein said parameters have a format that is different from a format of parameters of an orbit model defined for said satellite based positioning system or have been derived from another source than broadcast satellite data.

Abstract
For supporting a satellite based positioning of a mobile arrangement (30,40) with assistance data, a communication network converts parameters of a dedicated orbit model describing a movement of a satellite (50,60), which dedicated orbit model is defined for a particular satellite based positioning system, into parameters of a common orbit model describing a movement of a satellite (50,60). Alternatively or in addition, the network replaces a reference value that is based on a satellite based positioning system time in available parameters of an orbit model by a reference value that is based on a communication system time. After the parameter conversion and/or the reference value replacement, the parameters are provided as a part of assistance data for the satellite based positioning. Alternatively or in addition, a set of data is transmitted in one direction between the mobile arrangement and the communication network, which is independent of the employed positioning mode.
