Method and apparatus for identifying transmitters in a wireless communication system using power predictions

Identification of transmitters for signals received by a terminal. To determine the transmitter of a given received signal, a list of candidate transmitters that may have transmitted that signal is determined. A coverage zone to use for the received signal is also determined. This coverage zone is the area where the terminal may receive the signal being identified. The predicted power for each candidate transmitter is then determined, e.g., using a path loss prediction model and the coverage zone. The predicted powers for the candidate transmitters are compared (directly or relatively) against the measured power of the received signal. The candidate transmitter with (direct/relative) predicted power closest to the (direct/relative) measured power is deemed as the one that transmitted the signal. Propagation delays may also be predicted and used for transmitter identification. The identified transmitters may be used to determine a position estimate for the terminal.

Maintaining location based service session continuity during inter-rat mobility

When a user equipment engaged in mobile communications transfers from a network with one radio access technology (RAT) to another network with a different radio access technology, maintaining continuity of location based services can improve system performance. A user equipment may perform a series of checks when undergoing inter-RAT transfer to determine if a location based services protocol used with the source network is operable on the target network. The UE also determines if location based services sessions are at a point where they can be continued following inter-RAT transfer. Where possible, protocols and sessions are maintained to preserve location based services continuity.

A dual SIM mobile terminal, such as a Dual SIM Dual Active (DSDA) mobile terminal, connects to a network and performs a user plane or control plane positioning session through the network. When the positioning session is originated by the mobile terminal, either SIM card may be used to connect to its associated network. When the positioning session is originated by another entity in the network, either SIM card may be used for the positioning session. When the mobile terminal connects to a network for an emergency call using either SIM card and an emergency positioning session is performed through the network, the emergency positioning session is permitted only during the emergency call and an emergency callback period and permitted only on a subscription on which the emergency call originated, and no non-emergency positioning sessions with either SIM card is permitted during the emergency positioning session or emergency call.
