Filed: 1995-07-13
Abstract: A private communications network system allows a mobile station to be used in a different private communications network than that in which it is registered, by a method of authenticating the mobile station outside of its home private communication network. When a mobile station 17 requests location registration in a private communications network 2 in which the mobile station 17 is not registered, a control unit 22 of a PBX 21 in the private communications network 2 requests a network common data management unit 3 to send group data which is used to identify a private communications network 1 in which the mobile station 17 is registered. Control unit 22 then requests a PBX 11 in a private communications network 1 to send subscriber data 33 of the mobile station 17. The mobile station 17 is authenticated in the private communications network 2 by the subscriber data 33 sent from its home private communications network 1, whereafter the mobile station 17 can make calls from or can receive incoming calls in the private communications network 2. Billing data for calls the mobile station has made in the private communications network 2 is transferred and stored in the home network common data management unit 3 on a group basis.

Title: A Wide Bandwidth Discriminator for Use in a Radio Receiver
Inventor: FREEBURG THOMAS A
IPC: H04B1/10
Filed: 1995-02-06
Abstract: A wide bandwidth frequency discriminator circuit (200) employs a wide bandwidth limiting amplifier (202) to amplify the IF signal portion a received RF signal. A delay circuit (204), such as a micro strip transmission line, provides a delayed representation of the amplified signal to a multiplier circuit (206). The multiplier (206) in turn provides a product signal which is the product of the amplified output signal and the delayed representation of the amplified output signal. As will be appreciated, said product signal will be proportional to the phase difference between the amplified output signal and the delayed representation of the amplified output signal. This discriminator (200) operates to form a detection system capable of discriminating between desired and undesired components of the received RF signal even when said desired and undesired components are nearly identical in amplitude. This is due in part to the enhanced frequency response provided by the discriminator (200).
