Abstract: A method of operation of a mobile network (1) comprising network core central nodes including a switching node and at least one remote node (4, 5) linked with the central nodes via a remote backhaul communication link (3). The method performs local connection of data or voice sessions. A remote node (4, 5) extracts, from signals, information concerning said devices to populate a database, and accesses said database when deciding whether to connect the call locally. The information includes device capability information including codec capabilities of the originating and terminating devices (MS-A, B, C). A remote node alters signalling information concerning codec capabilities of at least one of the devices (MS-A, B, C) to force use of the same codecs during the session. In one example, the information is extracted from a Bearer Capability field in a Call Confirmed message sent back from the terminating device and stored in the database for use in subsequent decisions concerning local connections of sessions.

Abstract: A mobile network comprises remote base transceiver station (BTS) nodes (3, 4) linked with a central base station controller (BSC) node (9). The latter is in turn linked with a mobile switching center (MSC, 10), a visitor location register (VLR, 11), and a home location register (HLR, 8). Mobile stations (2, MS-A, MS-B, and MS-C) are located in the cells of the BTSs (3, 4). The remote nodes (3, 4, 3(a), 4(a)) are connected to the central node BSC (9) over a remote backhaul satellite connection. Calls are routed locally while the central nodes continue to manage calls and services from central feature-rich and typically more reliable switches of a core network. This means that calls set up between subscribers on the same remote node get connected within the remote node but call supervision is still carried out by the central nodes. The features and services of the existing core network are preserved.

Abstract: A communication system comprises an adapter (10) having interfaces (25-27) linked with user device components (12). A terminal controller (29) dynamically associates the components in real time to provide mobile stations. Thus, passengers of an aircraft can insert SIM cards into conveniently-located readers (22) and use in-flight entertainment i/o devices to make and receive cellular calls. The adapter (10) also has a BTS emulator (30) for direct communication with a BSC (3) with non-wireless internal network communication. This avoids the need for a mobile station to BTS wireless link.

Abstract: A ground fault circuit interrupter which continues to provide ground fault protection in the event of loss of neutral includes a blocking means formed by a pair of back-to-back Zener diodes which complete an energizing path for a circuit breaker on loss of neutral. The circuit interrupter also includes a standby rectifier circuit formed by a pair of diodes which complete a full wave rectifier having line and earth inputs in the event of loss of neutral.
