Embodiment Construction

[0065] figure 1 is a schematic block diagram of an exemplary embodiment of an apparatus according to the first aspect of the invention.

[0066] In this embodiment, the device 100 includes a processor 101 and a memory 102 . The memory 102 stores computer program code for generating a request for positioning data, for causing transmission of the request and for receiving a response. Processor 101 is configured to execute computer program code stored in memory 102 to cause the device to perform desired actions.

[0067] will now refer to figure 2 The flow chart of FIG. 1 illustrates the operation of the device 100. This operation is an exemplary embodiment of the method according to the first aspect of the invention. The program code stored in processor 101 and memory 102 causes device 100 to perform operations when the program code is retrieved from memory 102 and executed by processor 101 .

[0068] Processor 101 generates a request for positioning data. The request inc...

Abstract

The first device generates a request for positioning data, includes in the request an indication that an estimate of the requested amount of positioning data is to be provided, and causes transmission of the request. The second device receives the request, generates a response including an estimate of the requested amount of positioning data, and causes transmission of the response. The first device receives the response.

Description

technical field [0001] The invention relates to the field of positioning of mobile devices, and more particularly to the exchange of messages related to positioning data. Background technique [0002] The location of a mobile device can be determined in a variety of ways. [0003] For example, the location of a mobile device may be determined based on satellite signals received at the mobile device including or connected to a Global Navigation Satellite System (GNSS) receiver. The mobile device determines its position based solely on the received satellite signals, or additionally on the basis of assistance data provided by the server. The latter method is called Assisted GNSS (AGNSS). Assistance data may include, for example, an almanac that represents satellite orbits and enables the mobile device to determine the satellite's position at a given time. Since almanacs have a limited validity time, they must be provided repeatedly. Exemplary GNSS are Global Positioning Sy...
