ABSTRACT:
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 network also selectively sends to the UE a pre-session command for an action related to position determination. For example, the command may direct the UE to (1) clear all or a portion of location-related data at the UE prior to performing the position fix, (2) send back a position estimate for the UE, if available, or (3) apply a time offset and/or a position offset in performing the position fix. The UE sends to the network an acknowledgment (e.g., a grant of permission) to perform the position fix. The UE also performs the action indicated by the command (if any) received from the network prior to or in conjunction with performing the position fix. The network and UE perform the position fix for the UE.
