Abstract

A method includes: receiving a request at a Secure User Plane Location (SUPL) Location Platform (SLP) for location-related service; producing a positioning method SUPL message that includes a posmethod parameter that includes a positioning protocol indicator indicating that SET capability transfer and positioning method selection are to be conducted in a positioning protocol layer; and sending the positioning method SUPL message from the SLP to a SUPL Enabled Terminal (SET) using a SUPL User Plane Location Protocol (ULP).

First claim

What is claimed is:

1 . A server comprising:
a transceiver configured to send messages to a Secure User Plane Location (SUPL) Enabled Terminal (SET) and to receive messages from the SET; and a processor communicatively coupled to the transceiver and configured to send a positioning method SUPL message to the SET via the transceiver using a SUPL User Plane Location Protocol (ULP); wherein the positioning method SUPL message includes a posmethod parameter; and wherein the posmethod parameter includes a positioning protocol indicator indicating that SET capability transfer and positioning method selection are to be conducted in a positioning protocol layer.

2 . The server of claim 1 , wherein the processor is configured to respond to the processor sending the positioning method SUPL message with the positioning protocol indicator by ignoring SUPL ULP information from the SET indicating SET capability information.

3 . The server of claim 1 , wherein the processor is configured to send the positioning method SUPL message including the positioning protocol indicator as part of a SUPL INIT message, a SUPL RESPONSE message, or a SUPL TRIGGERED RESPONSE message.

4 . The server of claim 1 , wherein the processor is configured to send to the SET a specified-data SUPL message using SUPL ULP that indicates that specified data that are to be transferred between the server and the SET in the positioning protocol layer only.

5 . The server of claim 4 , wherein the specified data are positioning data.

6 . The server of claim 4 , wherein the processor is configured to send the positioning method SUPL message and the specified-data SUPL message in a single message.

7 . The server of claim 1 , wherein the positioning protocol indicator specifies a positioning protocol.

8 . A method comprising:
receiving a request at a Secure User Plane Location (SUPL) Location Platform (SLP) for location-related service; producing a positioning method SUPL message, wherein the positioning method SUPL message includes a posmethod parameter, and wherein the posmethod parameter includes a positioning protocol indicator indicating that SET capability transfer and positioning method selection are to be conducted in a positioning protocol layer; and sending the positioning method SUPL message from the SLP to a SUPL Enabled Terminal (SET) using a SUPL User Plane Location Protocol (ULP).

9 . The method of claim 8 , further comprising:
receiving, at the SLP, a responsive SUPL ULP message from the SET responsive to the positioning method SUPL message, the responsive SUPL ULP message including SET capability information; and ignoring, by the SLP, the SET capability information in the responsive SUPL ULP message in response to sending the positioning method SUPL message including the posmethod parameter including the positioning protocol indicator.

10 . The method of claim 8 , wherein the positioning method SUPL message is one of a SUPL INIT message, a SUPL RESPONSE message, or a SUPL TRIGGERED RESPONSE message.

11 . The method of claim 8 , further comprising sending a specified-data SUPL message to the SET, using SUPL ULP, indicating specified data that are to be transferred between the SLP and the SET in the positioning protocol layer only.

12 . The method of claim 11 , wherein the specified data are positioning data.

13 . The method of claim 11 , wherein sending the positioning method SUPL message and sending the specified-data SUPL message comprise sending a single message.

14 . The method of claim 8 , wherein the positioning protocol indicator specifies a positioning protocol.

15 . A Secure User Plane Location (SUPL) Enabled Terminal (SET) comprising:
a transceiver configured to send messages to a SUPL Location Platform (SLP) and to receive messages from the SLP; and a processor communicatively coupled to the transceiver and configured to:
receive a positioning method SUPL message, in a SUPL User Plane Location Protocol (ULP), from the SLP via the transceiver;
determine that the positioning method SUPL message includes a posmethod parameter that includes a positioning protocol indicator; and
in response to the positioning protocol indicator indicating that SET capability transfer and positioning method selection are to be conducted in a positioning protocol layer:
provide SET capability information to the SLP using the positioning protocol layer; and
interact with the SLP to select a positioning method using the positioning protocol layer.

16 . The SET of claim 15 , wherein the positioning method SUPL message is one of a SUPL INIT message, a SUPL RESPONSE message, or a SUPL TRIGGERED RESPONSE message.

17 . The SET of claim 15 , wherein the processor is configured to:
receive a specified-data SUPL message from the SLP indicating specified data that are to be transferred from the SET to the SLP in the positioning protocol layer only; and send the specified data to the SLP using only the positioning protocol layer in response to receiving the specified-data SUPL message.

18 . The SET of claim 17 , wherein the specified data are positioning data.

19 . The SET of claim 17 , wherein the processor is configured to receive the positioning method SUPL message and the specified-data SUPL message as a single message.

20 . The SET of claim 15 , wherein the positioning protocol indicator indicates a specified positioning protocol and the processor is configured to use the specified positioning protocol to provide the SET capability information to the SLP and to interact with the SLP to select the positioning method.

21 . A method comprising:
receiving a positioning method Secure User Plane Location (SUPL) message from a SUPL Location Platform (SLP); determining that the positioning method SUPL message includes a posmethod parameter that includes a positioning protocol indicator indicating that SET capability transfer and positioning method selection are to be conducted in a positioning protocol layer; in response to the positioning protocol indicator indicating that SET capability transfer and positioning method selection are to be conducted in a positioning protocol layer, providing SET capability information to the SLP using the positioning protocol layer; and interacting with the SLP to select a positioning method using the positioning protocol layer in response to the positioning method SUPL message including the posmethod parameter including the positioning protocol indicator.

22 . The method of claim 21 , wherein the positioning method SUPL message is one of a SUPL INIT message, a SUPL RESPONSE message, or a SUPL TRIGGERED RESPONSE message.

23 . The method of claim 21 , further comprising:
receiving a specified-data SUPL message from the SLP indicating specified data that are to be transferred from the SET to the SLP in the positioning protocol layer only; and sending the specified data to the SLP using only the positioning protocol layer in response to receiving the specified-data SUPL message.

24 . The method of claim 23 , wherein the specified data are positioning data.

25 . The method of claim 23 , wherein receiving the positioning method SUPL message and the specified-data SUPL message comprise receiving a single message.

26 . The method of claim 21 , wherein the positioning protocol indicator indicates a specified positioning protocol and wherein providing the
