Abstract: A mobile communication device including a wireless transceiver and a processor is provided. The wireless transceiver is configured to perform wireless transmission and reception to and from an advanced network and a legacy network. The processor is configured to perform a Secure User Plane Location (SUPL) session with a SUPL server when the mobile communication device is camped on the advanced network, and transmit a SUPL message including cell information of the legacy network to the SUPL server via the wireless transceiver in response to performing the SUPL session with the SUPL server.

Abstract: The mobile communication device supports a plurality of RATs and includes a first wireless transceiver, a second wireless transceiver, and a controller. The first wireless transceiver performs wireless transmission and reception to and from a first cellular network utilizing a first RAT. The second wireless transceiver obtains a non-cellular signal indicator. The controller determines whether the first RAT is a predetermined one of the plurality of RATs when the mobile communication device camps on the first cellular network, and if not, predicts whether there is a second cellular network available, which utilizes the predetermined RAT, based on the non-cellular signal indicator. In response to predicting that the second cellular network is available based on the non-cellular signal indicator, the controller further enables the mobile communication device to camp on the second cellular network via the first wireless transceiver.
