A terminal for use in a voice communications system includes a base station and at least one handset arranged to communicate wirelessly with the base station. The base station includes a first interface to a packet data network and a second interface to a public switched telephone network, the base station being arranged to selectively establish a packet data call from the first interface and a public switched telephone call from the second interface.

Dual-mode device for voice communication

A method of transmitting a communication event from a calling entity to a called entity located in a communication system comprising a first network and a second network, said method comprising determining a first identity associated with the calling entity and a first and second identity associated with the called entity, wherein the first identities are recognizable in the first network and the second identity is recognizable in the second network; associating at a first node located in the second network the first identities with the second identity; establishing a connection between the calling entity and a second node; wherein the connection with second node is established using the first identity associated with the called entity; querying the first node with the first identity associated with the called entity and the first identity associated with the calling entity to determine the second identity associated with the called entity; and transmitting the communication event to the called entity using the second identity associated with the called entity.

Communication system

A data store associates a first identity recognizable in a first network with a second identity recognizable in a second network for both a user and a calling entity. Both identities for the calling entity are provided to the receiving device via the second network. A node receives the communication event with the second identity for the calling entity, the communication event being addressed with the second identity of the user. The data store is queried with the second identities of the calling entity and user to determine the first identities of the calling entity and user. The receiving device receives the communication event with the first identity for the calling entity via the first network, the communication event being addressed with the first identity of the user. The receiving device determines the second identity of the calling entity using the first identity of the calling entity.

Communicaton system

A wireless handset for use in a peer-to-peer voice communications system comprising: a display; a keyboard comprising multifunctional keys capable of entering numeric or alphabetic characters depending on a number of key presses, said keyboard being arranged to enter contact information into a user interface displayed on said display, select contacts on the user interface, and initiate a packet data voice call with a contact; a microprocessor arranged to execute embedded client software, wherein the client software is arranged to establish a packet data voice call over the network and encode speech information as individually addressed packets; and a radio communication device arranged to transmit said individually addressed packets as radio signals from said wireless handset to a network.

Wireless device for voice communication

A method of transmitting a communication event from a calling entity to a called entity located in a communication network comprising a first network and a second network, said method comprising determining a first identity associated with the called entity, wherein the first identity is recognizable in the first network; allocating a calling identity to the called entity, wherein the allocated identity is recognizable in the second network; associating at a first node located in the first network the first identity with the calling identity; providing the calling identity to the calling entity; establishing a connection with a second network node located in the second network; wherein the connection with the second network node is established using the calling identity, querying the first node with the calling identity associated with the called entity to determine the first identity associated with the called entity; transmitting the communication event to the called entity using the first identity associated with the called entity; and disassociating the calling identity from the called entity after querying the first node to determine the first identity associated with the called entity.

A terminal for use in a peer-to-peer voice communications system comprising: a base station; and at least one handset arranged to communicate wirelessly with said base station; wherein the base station comprises a first interface to a packet data network and a second interface to a public switched telephone network, said base station being arranged to selectively establish a packet data call from said first interface and a public switched telephone call from said second interface.
