1. A method of selectively permitting and prohibiting cell selection of a communication with a mobile terminal between a first wireless network and a second wireless network each network comprising at least one base station transceiver, said method comprising the steps of:
- appointing an area covered by one base station transceiver of one network as a gateway area between the first and second networks;
determining whether or not the mobile terminal is located within the gateway area;
permitting cell selection of the communication with the mobile terminal between a cell within the first wireless network and a cell within the second wireless network when the mobile is within the gateway area; and
prohibiting cell selection of the communication with the mobile terminal between a cell within the first wireless network and a cell within the second wireless network when the mobile terminal is outside the gateway area.

Abstract
Apparatus, and an associated method, controls operation of a mobile terminal operable in a communication system having two network portions. Selective permission of cell selection of communications between the two network portions better assures that the mobile terminal, when positioned in an area intended to be encompassed by one of the network portions, communicates with that network portion.

13. A method of selectively permitting and prohibiting a handover of a communication with a mobile terminal between a first wireless network and a second wireless network, each network comprising at least one base station transceiver, said method comprising the steps of:
-
appointing one base station transceiver of one network as a gateway transceiver between the first and second networks; determining whether or not the mobile terminal is located within an area covered by said gateway transceiver; permitting said handover of said communication with the mobile terminal between a cell within the first wireless network and a cell within the second wireless network when the mobile is within the area covered by said gateway transceiver; and prohibiting said handover of said communication with the mobile terminal between a cell within the first wireless network and a cell within the second wireless network when the mobile terminal is outside the area covered by said gateway transceiver. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. In a method for communicating in a communication system having a first wireless network permitting a mobile terminal to communicate therewith when positioned in a first area, the first area intended to be encompassed by the first wireless network and a second wireless network permitting the mobile terminal to communicate therewith when positioned in a second area, the second area intended to be encompassed by the second wireless network, an improvement of a method for selectively permitting cell selection of a communication with the mobile terminal between the first and second wireless networks, respectively, each network comprising at least one base station transceiver, said method comprising the steps of:
-
detecting when the mobile terminal is positioned at a selected gateway area, the selected gateway area defining a gateway between the first wireless network and the second wireless network, the selected gateway area being an area covered by one base station transceiver of one network; generating a signal indicative of detection during said step of detecting the position of the mobile terminal at the selected gateway area; permitting the cell selection of the communication with the mobile terminal between a cell within the first wireless network and a cell within the second wireless network when the signal indicative of the position of the mobile terminal at the gateway area is generated during said step of generating; and
, otherwiseprohibiting the cell selection of the communication with the mobile terminal between a cell within the first wireless network and a cell within the second wireless network.

21. In a communication system having a first wireless network permitting a mobile terminal to communicate therewith when positioned in a first area having at least one cell, the first area intended to be encompassed by the first wireless network and a second wireless network permitting the mobile terminal to communicate therewith when positioned in a second area having at least one cell, the second area intended to be encompassed by the second wireless network, and improvement of apparatus for selectively permitting cell selection of a communication with the mobile terminal between the first and second wireless networks, respectively, each network comprising at least one base station transceiver, said apparatus comprising:
-
at least one detector for detecting when the mobile terminal is positioned at a selected gateway area, the selected gateway area defining a selected gateway between the first wireless network and the second wireless network, the gateway area being an area covered by one base station transceiver of one network, said at least one detector further for generating a signal indicative of detection of the position of the mobile terminal at the selected gateway area; and a controller coupled to receive the signal indicative of the position of the mobile terminal at the gateway area, said controller for permitting the cell selection between a cell within the first wireless network and a cell within the second wireless network when the signal indicative of the position of the mobile terminal at the gateway area is received thereat and for prohibiting the cell selection between a cell within the first wireless network and a cell within the second wireless network if the controller fails to receive the signal indicative of the position of the mobile terminal at the selected gateway area. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. An assembly for selectively permitting and prohibiting a handover of a communication with a mobile terminal from a first wireless network and a second wireless network, each network comprising at least one cell having a base station transceiver, said assembly comprising:
-
a detector positioned at, and defining a gateway area covered by one base station transceiver of the second wireless network; a determiner coupled to receive indications of detection by said detector of positioning of the mobile terminal within the gateway area; and a handover controller operably responsive to determinations of said determiner, said handover controller for permitting said handover of said communication with said mobile terminal between a cell within the first wireless network and a cell within the second wireless network when the mobile terminal is determined to be within the gateway area and for prohibiting said handover of said communication with said mobile terminal between a cell within the first wireless system portion and a cell within the second wireless system portion when the mobile terminal is outside the gateway area.
