Handover method (roaming) for mobile terminal devices
First Claim
1. A method for controlling a switching device that can be used to establish wire-free connections with mobile terminal devices through coupled base stations, which comprises:
- when a mobile terminal device logs on at a base station, communicating a terminal equipment identifier from the mobile terminal device to the base station that identifies the mobile terminal device to the base station;
communicating, from the base station to a switching device, the terminal equipment identifier and a control information item for activating a forwarding feature in the switching device; and
if a connection request is directed to the mobile terminal device, initiating a connection setup to be routed through the base station as a result of the communication.

Abstract
In the course of its logging on at a base station (B2) coupled to a switching device (V), a mobile terminal device (E1) transmits a terminal equipment identifier (EK1) identifying the mobile terminal device (E1) to the base station (B2). The base station (B2) thereupon transmits the terminal equipment identifier (EK1)—if appropriate together with a base station identifier (BK2) identifying the base station (B2)—to the switching device (V) and initiates the activation of a forwarding performance feature, e.g. for call diversion, known per se in connection with wire-based terminal equipment, in the switching device (V). As a result of the activation of this forwarding performance feature, a connection setup to be routed via the base station (B2) is initiated in the event of connection requests directed to the mobile terminal device (E1). As a result, a central radio switching assembly, as required in known handover methods, is unnecessary.

3. A method for controlling a switching device that can be used to establish wire-free connections with mobile terminal devices through coupled base stations, which comprises:
-
when a mobile terminal device logs on at a first base station that is coupled to a switching device through at least one interposed base station, communicating a terminal equipment identifier from the mobile terminal device to the first base station that identifies the mobile terminal device to the first base station;
defining a directly connected base station by directly connecting one—
at least one interposed base station to the switching device;
passing on the terminal equipment identifier from the first base station to the directly connected base station;
communicating, from the directly connected base station to a switching device, the terminal equipment identifier and a control information item for activating a forwarding feature in the switching device; and
if a connection request is directed to the mobile terminal device, initiating a connection setup to be routed through the first base station as a result of the communication. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13)
