Abstract:
The invention concerns the transfer of messages using an UDP transport. A typical example is offered by the SNMP messages, used to perform the communication (Cl, C2) between manager units (M, M') and agent units (A, A') within a system for the management of data communication networks, such as internet. The payload of messages and preferably the messages as a whole shall undergo a compression operation based on the recognition of sequences that periodically appear in the message.
Abstract:
A system for wireless remote control of a gateway and ordering or invocation of services provided by a headend. The remote control includes a video display and user input device or keyboard and can decompress and display compressed streaming video in some embodiments. Some species of the remote control can act as web browsers, appliance control, TIVO function control, an IP telephony telephone, a cellular telephone and /or an MP3 player. In some embodiments, the gateway and/or headend can implement TIVO-like functions under control from a wireless remote of custom design or implemented on a Personal Digital Assistant.
Abstract:
A packet centric wireless point-to-multipoint (PtMP) telecommunications system is provided. The telecommunications system includes a wireless network that provides for true QoS. A media access control (MAC) layer is used in a packet-centric wireless point to multi-point (PtMP) telecommunications system, the telecommunication system includes a wireless base station coupled to a first data network, one or more host workstations coupled to the first data network, one or more subscriber customer premise equipment (CPE) stations in wireless communication with the wireless base station over a shared bandwidth using a packet-centric protocol, and one or more subscriber workstations coupled to each of the subscriber CPE stations over a second network. The MAC layer includes a resource allocation means that allocates shared bandwidth among the subscriber CPE stations to optimize end-user quality of service (QoS).
Abstract:
The invention relates to a communication system and method wherein a user equipment contains, or is provided with, a list of items of service-related information. The list of service-related information represents a list of service provider names, services and/or service types or the like. When intending to establish or modify a session or connection or use a service, the user equipment selects, in one of the embodiments, an item from the list and performs a DNS query to resolve the name of the selected item to an IP address which then is used for set-up. The list may be provided by an DHCP server or in a PDP context message.The list may comprise one or more service provider default names, in particular for visited and home networks.
Abstract:
A first computer (12) transmits data to a second computer (21) in accordance with a first protocol. The second computer (21) receives the data and transmits them to a third computer (11), which is within a secure network, using a second protocol that is different from the first protocol. The data is transmitted to the third computer over a connection originated from within the secure network, thereby allowing the data to pass through network security devices such as firewalls (15).
Abstract:
Methods and apparatus are provided for reserving resources in a wireline network from a wireless network. A resource reservation request is made by a service client to a service broker (SB). The service broker (SB) contacts a bandwidth broker (BB) to determine the available resources in the wireline network. The service broker (SB) also contacts a geographical domain server (GDS) for information related to wireless access for the requested reservation. Using information provided by the geographical domain server (GDS), the service broker (SB) contacts a radio bearer broker (RBB) to determine the resources available in a particular wireless network. Based upon the information provided by bandwidth brokers (BB) and radio bearer brokers (RBB), the service client can reserve the requested resources.
Abstract:
A messaging proxy system is disclosed for the purpose of delivering data in the form of a portable message formate from a producer running on a mobile or non-mobile computer, over any wireless network, by passing this data through an intermediary proxy computer program, to one or more recipients running on mobile or non-mobile computers. The system includes a message proxy computer program with at least one pluggable transport protocol adapter. The proxy contains a command subsystem for sending and receiving command- and message-tokens to and from the mobile clients. The system further includes a thin messaging middleware client to run on mobile devices. The thin messaging middleware client includes at least one pluggable protocol adapter. The client also comprises a command subsystem for sencing and receiving command- and message-tokens to and from the proxy. The proxy also contains a communication subsystem for sending and receiving messages via a state of the art message oriented middleware.
Abstract:
The present invention relates to a method of achieving communication via a network with the aid of a wireless application protocol (WAP) between a first application (A1) in a first computer unit (A) and a second application in a second computer unit, wherein said first application (A1) is a Windows3 application. The first computer unit (A) includes a WinSock TCP base provided (2) operating beneath WinSock SPI (3), and a TCP/UDP/IP stack (4) operating beneath said WinSock TCP base provider (2). The first application (A1) includes a function for communicating by means of TCP/IP via the TCP/UDP/IP stack (4) and the WinSock TCP base provider (2). The first computer unit (A) also includes a module (5) and a WAP stack (6). The module (5) includes the function of forming an interface between said WAP stack (6) and the first application (A1).
Abstract:
The invention provides a method, data processing system and software for generating address identifier for use in a communications network. The method comprises the step of processing a first address identifier constructed in accordance with a first communications protocol; and the step of constructing a second address identifier, from said first identifier, in accordance with a second communications protocol. The first communications protocol may be protocol Simple Mail Transfer Protocol (SMTP) and the second communications Session Initiation Protocol (SIP). The invention enables messages to be sent to a SIP URL derived from an SMTP email URL. In the event that the SIP URL is invalid, or unregistered the SIP message is diverted from a SIP defined destination URL address identifier to a corresponding SMTP defined destination URL address identifier for the same user or end system. In this way users may send SIP messages to SMTP address identifiers using the SMTP network protocol and infrastructure (416) and SMTP messages to SIP address identifiers using the SIP network protocol and infrastructure (408, 410, 412).
Abstract:
A packet-centric wireless point to multi-point telecommunications system includes: a wireless base station communicating via a packet-centric protocol to a first data network; one or more host workstations communicating via the packet-centric protocol to the first data network; one or more subscriber customer premise equipment (CPE) stations coupled with the wireless base station over a shared bandwidth via the packet-centric protocol over a wireless medium; and one or more subscriber workstations coupled via the packet-centric protocol to each of the subscriber CPE stations over a second network. The packet-centric protocol can be transmission control protocol/internet protocol (TCP/IP). The packet-centric protocol can be a user datagram protocol/internet protocol (UDP/IP). The system can include a resource allocation means for allocating shared bandwidth among the subscriber CPE stations. The resource allocation is performed to optimize end-user quality of service (QoS).
