摘要：
Methods and systems are disclosed for processing satellite positioning system (SPS) signals at a mobile device. In an embodiment, SPS signals may be acquired at multiple instances over a first duration while the mobile device is camped on one or more signals transmitted by a first access device (202). The mobile device may then determine a second duration of time to acquire a subsequent SPS signal based, at least in part, on the acquired SPS signals, representations of system time in signals received from the first access device contemporaneously with acquisition of the SPS signals and an indication of stationarity of the mobile device during the first duration (204).
