Abstract:
PROBLEM TO BE SOLVED: To access to web system information service from a general telephone set or a cellular telephone set by accessing to a web storage place, retrieving requested information and supplying requested information to a user through the telephone set. SOLUTION: A gateway 40 requests an appropriate HTML page from an appropriate HTTP server 52. The HTTP server 52 supplies the page and software in the gateway 40 'reads' the HTML page through an HTTP protocol software 45 and extracts a specified content related to information which the user requests. Extracted information is converted into an appropriate end user related protocol (namely, colloquial sound, alphanumeric text or combination of them) by user presentation control software 43, and is transmitted to the telephone set of the user through a public telephone exchange network (PSTN) 22.
Abstract:
PROBLEM TO BE SOLVED: To disclose a method for accessing an e-mail by using a user agent from the cellular/personal communication service (PCS). SOLUTION: In a method for accessing a text file consisting of individual (personal) messages from the cellular telephone set, a text file is accessed and one of individual (personal) messages is selected. Then the selected message is formatted by using a user agent which is resident in a network and the formatted message is transmitted to the cellular telephone set.
Abstract:
PROBLEM TO BE SOLVED: To provide user mobility management between multiple systems that use protocols different in each other. SOLUTION: The multiple-protocol home location register(MP HLR) 101 comprises a receiver, which receives network requests in accordance with a network protocol from a requesting side network. A processor in the MP HLR 101 processes the network request and acquires information requested by the network request using a common data source and a common control procedure for the network protocol. A transmitter connected the processor relays the requested information to the requesting side network. The MP HLR 101 executes functions such as mobility/user management, user authentication/security control, and user profile management for various network protocols.
Abstract:
A system and method for using a window mechanism to control transmission of a multicast in a computer network to curb congestion. In one embodiment, the system includes: (1) a packet monitor that tracks, for each receiver of the multicast, unacknowledged packets transmitted to each receiver and (2) a multicast manager, associated with the packet monitor, that controls transmission of further packets of the multicast to prevent the unacknowledged packets transmitted to any of each receiver from exceeding a maximum number associated with each receiver.
Abstract:
The SoftRouter architecture separates the implementation of control plane functions from packet forwarding functions. In this architecture, all control plane functions are implemented on general purpose servers called the control elements (CEs) 200, 204 that may be multiple hops away from the forwarding elements (FEs) 202, 206. A network element (NE) or a router is formed using dynamic binding between the CEs and the FEs. The flexibility of the SoftRouter architecture over conventional routers with collocated and tightly integrated control and forwarding functions results in increased reliability, increased scalability, increased security, ease of adding new functionality, and decreased cost.

Abstract:
An embodiment of the exemplary SoftRouter architecture includes two physically separate networks, a control plane network and a data plane network. The data plane network is one physical network for the data traffic, while the control plane network is another physical network for the control traffic. The topology of the data plane network is made up of interconnected forwarding elements (FEs) 506. The topology of the control plane network is made up interconnected control elements (CEs) 502. This physical independence of the control plane network from the data plane network provides for a secure mechanism to communicate among the CEs 502 in the control plane network. In addition, this physical independence provides improved reliability and improved scalability, when compared to the traditional router architecture, where control plane message are in-band with the data plane.
