A system for directing the rendering content includes a plurality of participants and a conferencing server. The participants include a source and at least one destination that are each capable of storing content. The source is capable of operating in a fixed network environment, and at least one of the destinations comprises a mobile terminal operating in a cellular network environment. The conferencing server is capable of establishing a conference session between the participants, where one of the participants is a host of the conference session and the other participants are members of the conference session. The conferencing server is capable of receiving control events from the host, and thereafter transferring the control events to the members. The members are then capable of rendering the content stored by the respective members in accordance with the control events.

A system for providing content to a mobile terminal includes a source and a messaging gateway. The source is capable of reformatting content intended for receipt by a terminal, and transferring the reformatted content and an address of the terminal to the messaging gateway. The content can be reformatted in any of a number of different manners, including for example, a vectorized format such as the scalable vector graphics (SVG) format. In response to receiving the reformatted content and address of the terminal, the messaging gateway is capable of signaling the terminal, the signaling including information required to access the reformatted content. As such, the terminal can thereafter send a request to the messaging gateway in response to the messaging gateway signaling the destination client, and thereafter download the reformatted content from the messaging gateway, such as at least partially across a cellular network.

A short-range RF network deployed at a site larger than the coverage area of a single short-range RF transceiver includes a plurality of short-range RF transceivers deployed with overlapping coverage areas and accessible through a gateway, and accommodates terminal devices to establish communication through any transceivers with the gateway or with other of the terminal devices. The system further includes a WAP/Web server in communication with the Internet and in communication with the gateway. Terminal devices may establish Internet sessions through a node, the gateway, the WAP/Web server, and the Internet with remote Web servers or with remote users, and are assigned PPP IP numbers for such sessions. A terminal device which roams from the coverage area of one node to the coverage area of another node, and which is accordingly assigned a new PPP IP number, may continue in an Internet session by virtue of a shared database associated with the WAP/Web server and updated by the gateway. The shared database enables correlation of the terminal device's current location in the network with the PPP IP number by which Internet communications refer to it.

The object of the invention is a method and a system for positioning a transmitter, wherein with receivers, the locations of which are known, the receiving delay of the timing signals of one or more transmitters, the locations of which are known, are measured with respect to the timing signal of the transmitter to be positioned, and by making use of these measurements numerically the place of the transmitter, the location of which is unknown, is determined. In the method, the receivers and the transmitters are substantially independent of each other, and the unknown transmitting delay between the timing signals is solved numerically.

A system for establishing and effectuating a conference session includes a plurality of participants. In turn, the participants include a source capable of operating in a fixed network environment, and at least one destination capable of operating in a cellular network environment. The participants are capable of establishing a conference session where one of the participants is a host and the other participants are members. During the conference session, then, the host is capable of sharing content with the members by reformatting content rendered for a local display into a vectorized format, and reformatting at least one update to the rendered content into a vectorized format. The host can transfer the reformatted content and reformatted update(s) to the members, which are then capable of rendering the respective reformatted content and reformatted update(s) in a manner at least partially in synch with the host rendering of the respective content and update(s).

摘要:
The invention relates to a method of transmitting a message from a wireless radio-frequency short-range communication network (20) via a gateway (21) to a network (14, 24) external to the communication network (20). The method comprises receiving a first message (41) via a short-range radio link at the gateway from a terminal device (23) of the short-range communication network (20), the first message being addressed to an element (25, 34) external to the short-range communication network, and the first message comprising a network address of said terminal device as a transmitter's address and a first port number as a source port number, the network address of the terminal device being used inside the short-range communication network. The method comprises allocating a second port number to the terminal device, replacing said network address of the terminal device in said first message (41) with the network address of the gateway and the first port number with said second port number, generating the correlation of the network address of the terminal device, the first port number and the second port number and storing said correlation in a memory available to the gateway for identification of the terminal device. The method comprises transmitting the first message from the gateway to the element external to the short-range communication network (20) with said replaced information. The invention also relates to a gateway and to computer software.
