    Abstract: A handover is performed between cells of different networks during a call. A call established between handset (18) and mobile handset MS1 through cell CA1 or mobile network PLMN A is handover during the call to PLMN B through cell CB1. Procedures to control inter-PLMN handovers are described in which the service provider for PLMN A supports the inter-PLMN handover as a supplementary service. Support of the service may be indicated in a classmark stored in EEPROM (9) of handset MS1 or on its SIM card (12). The service provider for PLMN A may include data in the classmark that indicates whether the user of the handset may selectively accept or decline inter-PLMN handovers. A procedure for carrying out a location update after release of the call is also described.
