A method of optimally communicating Assistance Data to a mobile station (MS) in a wireless network, the method comprising:
- providing a list of satellites;
- determining an optimal order of the satellites based on a characteristic of the mobile station, wherein the optimal order comprises a first optimal satellite and a second optimal satellite;
- preparing a first of a segmented set of Assistance Data messages in the wireless network, wherein the first of the segmented set of Assistance Data messages comprises
- reference information including a satellite time and a coarse MS location;
- and
- satellite vehicle position information for the first optimal satellite and the second optimal satellite;
- and
- beginning to transmit the first of the segmented set of Assistance Data messages from the wireless network to the mobile station.
A method of optimally communicating Assistance Data to a mobile station (MS) in a wireless network, the method comprising:
- providing a list of satellites;
- determining an optimal order of the satellites based on a characteristic of the mobile station, wherein the optimal order comprises a first optimal satellite and a second optimal satellite, and wherein the first optimal satellite and the second optimal satellite are selected based on being approximately orthogonally oriented with respect to the mobile station, and wherein the characteristic of the mobile station comprises a coarse MS location or an environmental characteristic related to the coarse MS location;
- preparing a first of a segmented set of Assistance Data messages in the wireless network, wherein the first of the segmented set of Assistance Data messages comprises
- reference information including a satellite time and the coarse MS location;
- and
- satellite vehicle position information for the first optimal satellite and the second optimal satellite;
- beginning to transmit the first of the segmented set of Assistance Data messages from the wireless network to the mobile station;
- and
- continuing to transmit subsequent messages of the segmented set of Assistance Data messages until a sufficient amount Assistance Data has been sent, wherein each subsequent segment of the segmented set of Assistance Data messages includes satellite position information for equal or less optimal satellites than previous messages.
A network for optimally communicating Assistance Data to a mobile station (MS) in a wireless network, the network comprising:
- memory comprising a list of satellites;
- logic to determine and produce an optimal order list of the satellites based on a characteristic of the mobile station, wherein the optimal order comprises a first optimal satellite and a second optimal satellite;
- memory to hold the optimally ordered list;
- and
- a transmitter to transmit a first of a segmented set of Assistance Data messages, wherein the first of the segmented set of Assistance Data messages comprises
- reference information including a satellite time and a coarse MS location;
- and
- satellite vehicle position information for the first optimal satellite and the second optimal satellite.
A network for optimally communicating Assistance Data to a mobile station (MS) in a wireless network, the network comprising:

- means for determining an optimal order of the satellites based on a characteristic of the mobile station, wherein the optimal order comprises a first optimal satellite and a second optimal satellite;
- means for preparing a first of a segmented set of Assistance Data messages, wherein the first of the segmented set of Assistance Data messages comprises
- reference information including a satellite time and a coarse MS location;
- and
- satellite vehicle position information for the first optimal satellite and the second optimal satellite;
- means for beginning to transmit the first of the segmented set of Assistance Data messages.
A computer-readable product comprising a non-transitory computer-readable medium comprising:
- code for causing at least one computer to provide a list of satellites;
- code for causing at least one computer to determine an optimal order of the satellites based on a characteristic of a mobile station (MS), wherein the optimal order comprises a first optimal satellite and a second optimal satellite;
- code for causing at least one computer to prepare a first of a segmented set of Assistance Data messages, wherein the first of the segmented set of Assistance Data messages comprises
- reference information including a satellite time and a coarse MS location;
- and
- satellite vehicle position information for the first optimal satellite and the second optimal satellite;
- and
- code for causing at least one computer to begin to transmit the first of the segmented set of Assistance Data messages.
