Dual-mode methods, systems, and terminals providing reduced mobile terminal registrations
First Claim
1. A method of operating a mobile terminal providing wireless communications, the method comprising:
- receiving communications service from a first communications network providing service over a first coverage area;
while receiving communications service from the first communications network, receiving a first identity code from a second communications network providing service over a plurality of second coverage areas wherein a first one of the second coverage areas includes the first coverage area and wherein the first identity code from the second communications network identifies availability of service with the second communications network in the first one of the second coverage areas;
after loss of communications with the first communications network, receiving a second identity code from the second communications network; and
when the second identity code from the second communications network is different than the first identity code from the second communications network, performing a registration with the second communications network so that communications service can be received by the mobile terminal from the second communications network in a second one of the second coverage areas corresponding to the second identity code from the second communications network.

Abstract
A method of operating a mobile terminal providing wireless communications can include receiving communications service from a first communications network providing service over a first coverage area. While receiving communications service from the first communications network, a first identity code can be received from a second communications network providing service over a plurality of second coverage areas wherein a first one of the second coverage areas includes the first coverage area and wherein the first identity code from the second communications network identifies availability of service with the second communications network in the first one of the second coverage areas. After loss of communications with the first communications network, a second identity code can be received from the second communications network. When the second identity code from the second communications network is different than the first identity code from the second communications network, a registration can be performed with the second communications network so that communications service can be received by the mobile terminal from the second communications network in a second one of the second coverage areas corresponding to the second identity code from the second communications network.

11. A mobile terminal providing wireless communications, the mobile terminal comprising:
-
a receiver that receives communications from a first communications network providing service over a first coverage area and a second communications network providing service over a plurality of second coverage areas wherein a first one of the second coverage areas includes the first coverage area, wherein while receiving communications service from the first communications network, the receiver receives a first identity code from the second communications network, wherein the first identity code from the second communications network identifies availability of service with the second communications network identifies availability of service with the second communications network in the first one of the second coverage areas, and wherein after loss of communications with the first communications network, the receiver receives a second identity code from the second communications network; and
a transmitter coupled to the receiver wherein when the second identity code from the second communications network is different than the first identity code from the second communications network, the transmitter performs a registration with the second communications network so that communications service can be received by the receiver from the second communications network in a second one of the second coverage areas corresponding to the second identity code from the second communications network. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
