Abstract: The objective of the invention is to provide a mobile communication control method and mobile communication system in which mobile IPv6 and SIP are integrated by a core network of 3GPP2. In the mobile communication system, the mobile node MN executes a registration procedure for a Care-of-Address acquired in a visited network by the communication between the mobile node and a home agent server HA, executes a registration procedure for the Care-of-Address by the communication between the mobile node and an SIP server, and executes a communication procedure for session establishment by the communication between the mobile node MN and a correspondent node not through the home agent server but through the SIP server.

Abstract: The present invention provides a method building a handover system to improve the service quality in mobile networks. When a mobile node has received a plurality of care-of addresses, it will send a Prepare Multi-path (PM) message to a correspondent node. Once receiving the PM message, each router replaces the old input label in the PM message with a new input label, and then sends it to the next router. Each router adds a new item into the Split Path Table based on the received message. After sending the PM message, the mobile node sends a Request Multi-path (RM) message to a correspondent node. Each MPLS core router decides whether to stop the RM message or not when the RM message is received. If it is yes, the corresponding input label will be split and the generated data packet will be transmitted to two paths from this router. One is the path in the network where the mobile node has been located, another one is a new path in the visiting network.

Abstract: A session QoS control apparatus includes a session management database in which session management information per user terminal is stored, a user preference database in which user preference information representing the user state and QoS requirement associated with the identifier of a user communication terminal is stored, and a user communication terminal and router management database in which mapping between a user terminal and a network node to which the terminal is connected is stored. Upon receiving user session information, the apparatus analyses the user session information by referring to the session management and user preference databases and determines a QoS policy for the session between and callee terminals. From the user communication terminal and router management database, the apparatus retrieves a node on which the session QoS policy should be set and transmits a QoS command to the node to set the session QoS policy on the node.

Abstract: A network is protected against interruption of service while one or more faulty switches or optical fiber transmission lines are repaired or replaced, by an interconnecting configuration of small N×N optical input/output switches, where N is 2 or greater than 2. The switches are configured among protection and working transmission lines. The small number of fibers for each switch improves repair and installation connection reliability and permits configurations that flexibly meet differing requirements. Also the fault is monitored with a fault check signal.

Abstract: The maximum number of virtual local area networks (VLANs) is increased beyond the number provided solely with the VLAN ID, by a factor related to the number of wavelengths of a Wavelength Division Multiplexing (WDM) used by a network switching. An optical VLAN number (OVLAN ID) is a combination of the VLAN ID from the packet header and a path or wavelength ID (WL ID) that identifies a selected one of available wavelengths of a WDM transmission line. An Optical VLAN (OVLAN) conversion table stores data of the OVLAN ID, the VLAN ID and optical path ID, for an optical VLAN node.
