20110249623 | SUPL 3.0 CONCEPT - Techniques for initiating and, if desired, modifying location services for Secure User Plane Location (SUPL) and other location architectures are described. To initiate SUPL service, a SUPL Location Platform (SLP) transmits a SUPL initial session message applicable to any service request to a SUPL enabled terminal (SET) and receives in response the service capabilities of the SET. The SLP selects and requests service from the SET consistent with the service capabilities of the SET. The SET may initiate SUPL service by requesting the service capabilities of the SLP. The SET selects and requests service from the SLP that is consistent with the service capabilities received from the SLP. The SET and SLP communicate to determine a position estimate for the SET. The service may be modified before or while communicating between the SET and the SLP to determine a position estimate for the SET. | 10-13-2011 |

20110319095 | METHOD AND APPARATUS FOR PERFORMING POSITION DETERMINATION WITH A SHORT CIRCUIT CALL FLOW - For a call flow to perform position determination, a network sends to a user equipment (UE) an indication (e.g., a request for permission) to perform a position fix for the UE. The UE responds by sending to the network an acknowledgment (e.g., a grant of permission) to perform the position fix. The UE selectively sends a position estimate for itself to the network, typically along with the acknowledgment. The network may initiate location processing if (1) a location estimate is not received from the UE or (2) a location estimate is received from the UE but the network decides not to use this location estimate. In this case, the network and the UE perform location processing to obtain a position fix for the UE. However, if a location estimate is received from the UE and the network decides to use the location estimate, then the location processing is bypassed or short circuited. | 12-29-2011 |
