摘要： A transceiver front-end for a communication device comprises a transmit frequency blocking arrangement and a receive frequency blocking arrangement. The transmit frequency blocking arrangement has a blocking frequency interval associated with the transmit frequency and a non-blocking frequency interval associated with the receive frequency, and is configured to block passage of transmit frequency signals between the signal transmission and reception arrangement and the receiver. The receive frequency blocking arrangement has a blocking frequency interval associated with the receive frequency and a non-blocking frequency interval associated with the transmit frequency, and is configured to block passage of receive frequency signals between the signal transmission and reception arrangement and the transmitter. One of the frequency blocking arrangements comprises a network of passive components including at least one transformer and a filter arrangement with a higher impedance at the blocking frequency interval than at the non-blocking frequency interval.

摘要： A method and arrangement for providing information to a client (200) from a client access network (202) regarding a requested set of users (204), at least some of which are connected to other access networks (206). In response to a client subscription request, the client access network establishes a network subscription with the other access networks. Information updates regarding users in the set are then continuously received and stored in a database (214) of the client access network, whenever the users change their state. In response to a subsequent request for user information from the client, corresponding stored user information is retrieved from the database and sent in a notification to the client.
