Claims44
A mobile terminal comprising:
- a GPS receiver to receive GPS data;
- a cellular transceiver to communicate with a wireless communications network;
- and wherein the mobile terminal generates GPS assistance data from the received GPS data, and transmits the GPS assistance data to a remote mobile terminal via the wireless communications network.
A mobile terminal comprising:
- a cellular transceiver to communicate with a wireless communications network;
- wherein the mobile terminal receives GPS assistance data via the wireless communications network that was generated by a remote mobile terminal from GPS data received by the remote mobile terminal;
- and
- wherein the mobile terminal determines a reference location based on the GPS assistance data received from the remote mobile terminal.
A method of exchanging GPS assistance data among mobile terminals communicating within a wireless communications network comprising:
- receiving, at a mobile terminal communicating in a wireless communications network, GPS data from an external source;
- generating, at the mobile terminal, GPS assistance data from the received GPS data;
- determining, at the mobile terminal, whether to transmit the GPS assistance data to a remote mobile terminal communicating in the wireless communications network;
- and
- transmitting the GPS assistance data to a remote mobile terminal via the wireless communications network based on the determination.
A method of exchanging GPS assistance data among mobile terminals communicating within a wireless communications network comprising:
- receiving, at a mobile terminal, GPS assistance data from a remote mobile terminal over a wireless communications network, the GPS assistance data being generated by the remote mobile terminal from GPS data received by the remote mobile terminal;
- determining whether to trust the GPS assistance data received from the remote mobile terminal as valid;
- and
- determining a reference location based on the GPS assistance data received from the remote mobile terminal.
