A conference call facility is described in which one () of a group of communication devices () connected to a low power radio frequency network () is able to set up a call to a party external of the network () and then selectively add further devices () to the call under the control of the user of the one device (). The users of the other devices () are able to enable or disable the selection of their device in a conference call. One or more of the communication devices may be a mobile radio telephone equipped with the necessary network interface ().

Conference call method and apparatus therefor

A radiotelephone handset has a housing having a front face to be presented to the face of the user when making a call, together with a user interface comprising an audio interface and a touch interface. The touch interface includes touch input means ( ) on another face ( ) of the housing to the front housing, for directing the processing of voice signals supplied to the audio interface.

A portable radio communication device having low power radio frequency unit, and having associated therewith a plurality of memory packs, the memory packs being situated remote from and external of the portable radio communication device, and the memory packs having a low power radio frequency unit associated respectively therewith, the portable radio communication device including data transfer means whereby the portable radio communication device is operable to read from and write to selectable ones of the memory packs, the data transfer means providing for the read/write data operations by low power radio frequency transfer between the low power radio frequency unit of the memory packs and the low power radio frequency unit of the portable radio communication device. One advantage of this invention is that bulky memory is not situated in the mobile phone handset itself, which is thus more compact.

Radiotelephone

A radiotelephone handset comprises a housing having a front and a rear face; and a user interface comprising a display ( ) and input means ( ) responsive to a user to manipulate the contents of the display ( ). The display ( ) is provided on the front face and the input means ( ) on the rear face of the handset.

Radiotelephone handset

A method for forming a character string, an electronic communication device (31) and a charging unit (29) for charging the electronic communication device, wherein the communication device (31) does not comprise at all number/letter keys used for the selection of a phone number. The numbers or letters are selected from a display (39; 41) by means of selecting keys (32-38). The invention can be exploited, for example, in portable mobile phones.

Method for forming a character string, an electronic communication

A telephone having a user interface, comprising user input means; output means; and control means responsive to a first actuation of the user input means to cause subsequent items to be indicated for selection by the output means, and responsive to another actuation of the user input means to select the currently-indicated item. The telephone could be a reduced user interface portable telephone.
