Abstract
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.
