Periodic assistance data flow control
First Claim
Patent Images
1. A method, comprising:
- receiving a first provide message, from a server, comprising periodic assistance data, said first provide message comprising a transaction identifier identifying a first transaction;
determining whether a change in periodic assistance data is to be made;
in response to determining that the change is to be made, transmitting, from a communication device, a request message with an information element, wherein the request message is configured to request to modify the periodic assistance data without triggering a new transaction in order to get modified periodic assistance data; and
the information element is configured to request the change in a set of virtual reference receivers (VRR) by requesting a transmission of reference assistance data for a first VRR and discontinuing an existing transmission of reference assistance data for a second VRR; and
receiving a second provide message, from said server, comprising the modified periodic assistance data, said second provide message comprising the transaction identifier identifying the first transaction;
wherein said provide messages and said request messages are linked by a periodic session identification parameter.

Abstract
An apparatus and method are provided for handling a periodic assistance session flow. Each periodic assistance data provision includes a session identification so that interlinked messages within the periodic assistance data delivery can be linked in the receiving end. Any modifications to the session are handled via the periodic session identification so that the changes to the assistance data delivery can be pointed to the right session.

8. A computer program product, embodied on a non-transitory computer-readable storage medium comprising computer code configured to cause an apparatus to perform the process of:
-
receiving, from a server, a first provide message comprising periodic assistance data, said first provide message comprising a transaction identifier identifying a first transaction; determining whether a change in periodic assistance data is to be made; in response to determining that the change is to be made, transmitting a request message with an information element, wherein the request message is configured to request to modify the periodic assistance data without triggering a new transaction in order to get modified periodic assistance data; and
the information element is configured to request the change in a set of virtual reference receivers (VRR) by requesting a transmission of reference assistance data for a first VRR and discontinuing an existing transmission of reference assistance data for a second VRR; andreceiving, from a server, a second provide message comprising the modified periodic assistance data, said second provide message comprising the transaction identifier identifying the first transaction; wherein said messages are linked by a periodic session identification parameter.
