Patent ID: 7706803

Claim:
A method for establishing communication between a mobile terminal and a telecommunications network, comprising: using a radio frequency (RF) backhaul in place of a wireline-based backhaul for handling a mobile call between the mobile terminal and the telecommunications network when distance or conditions render the use of wireline-based backhaul impossible; defining a base station as a RF-based base station in the telecommunications network; equipping at least the RF-based base station with a base station transceiver; equipping the telecommunications network with a network transceiver; using the base station transceiver and the network transceiver for backhaul traffic and signaling for incoming and outgoing mobile calls to the mobile terminal that is operatively coupled to the base station; and when the mobile terminal roams away from RF-based backhaul cell(s) zone boundaries, detecting, via the network, entry of the mobile terminal into a new zone and transitioning a mobile call from an RF-based backhaul to a wire-base backhaul; wherein the base station transceiver and the network transceiver are structured for backhaul traffic and signaling for incoming and outgoing mobile calls to the mobile terminal that is operatively coupled to the base station when distance or conditions render the use of wireline-based backhaul impossible; wherein, when the mobile terminal is located in an area where the base station is at a physical distance from the network such that there is no cellular service to the network, the mobile terminal is still able to communicate with the network due to an RF backhaul link between the network transceiver in the network and the base station transceiver in the base station; wherein the RF-based base station with the base station transceiver has at least one cell in which is located the mobile terminal, and wherein the RF-based base station, the mobile terminal, and the at least one cell are located at the physical distance from the network such that there is no cellular service to the network.
