1. A method comprising:
- generating a sequence of interlinked messages comprising assistance data for a satellite signal based positioning;
checking whether the assistance data that is to be included in a message of said sequence of interlinked messages has a desired continuity with the assistance data in a preceding message of said sequence of interlinked messages and including at least one corresponding continuity indicator in each message; and
providing the sequence of interlinked messages for transmission to a wireless communication terminal after said checking and including.

Abstract
For supporting the provision of a continuous stream of assistance data for a satellite signal based positioning, a sequence of interlinked messages comprising assistance data is generated. The messages are provided for transmission to a wireless communication terminal. The wireless communication terminal receives the sequence of interlinked messages and provides the assistance data in the received messages for use in positioning computations.
