Abstract: In a packet communication network comprising an MNO network, and an MVNO network including an application server for providing an information service to wireless terminals via the MNO network, the MNO network includes a subscriber-associated-information delivery controller for delivering subscriber associated information of each wireless terminal, which is connected to a radio access network, to the MVNO network, and the MVNO network includes a subscriber-associated-information processor for receiving the subscriber associated information delivered from the subscriber-associated-information delivery controller.

Abstract: An optical access network and optical switching systems requiring no frame delay process on an optical switchboard are disclosed. Plural ONUs are connected to user terminals. An OLT communicates with an IP network through an access gateway. An optical switching unit (OSW) connects the ONUs and the OLT by switching the optical line. A control line connects the OLT and the OSW to control the optical switch change-over operation in the OSW. The optical switch port information required to generate the optical switch activation signal are concentrated in the OLT, which transmits the optical switch change-over control signal to the OSW through the control line before the transmission frame.
