SEGMENTED DATA TRANSFER WITH RESUME CAPABILITY

摘要

A large volume of location related information, e.g., assistance data or location information, is transferred in separate messages between a server and a target by segmenting the location related information into a plurality of messages. If the connection between the server and target is released prior to completion of the transfer of the location related information, the transfer is resumed by sending the remaining messages after connection is reestablished. Each message is sent after receiving an acknowledgement of receipt. Thus, both the server and target can control the flow of the transfer by delaying the sending of one or more messages or delaying the sending of the acknowledgements of receipt.
