Abstract: An apparatus for transmitting software to a subscriber device in a communication network, which includes a processor, a database coupled to the processor, and a communication device for providing software to a subscriber device. The database contains information about subscribers of a communication network. A method for transmitting software to subscriber devices in a communication network, comprising identifying a subscriber device which requires a software update, transmitting a first signal from a processor to the subscriber device, initiating a communication channel between the subscriber device and the processor, and transmitting a second signal to the subscriber device. The second signal contains software.

Abstract: An interworking proxy is coupled to first and second mobile switching systems and translates between first and second management protocols used by the first and second systems, respectively. The first system requests service for a mobile user using the first management protocol. The proxy receives the service request and translates it from the first management protocol to the second management protocol, and then transmits the translated service request to the second system. The second system provides a response to the service request using the second management protocol. The interworking proxy receives the response and translates it from the second management protocol to the first management protocol, and then transmits the translated response to the first system.

Abstract: A technique for handing over between PCS networks that are connected to the ISDN/AIN switches wherein the PCS networks have source-centric hand over and the ISDN/AIN switching infrastructure has target-centric hand over by using AM components.
