Abstract: A data structure defining a presence protocol, a device, a server, a system and method to provide management of presence information as a standalone service as well as part of the instant messaging service of a communication system.

Abstract: A mobile telephone terminal provides a user with a selectable option to transfer a telephone call to an instant messaging session and to transfer an instant messaging session to a telephone call. A presence attribute indicator for a first party is displayed with an entry associated with the telephone number of the first party. A user has a selectable option for initiating instant messaging with the party. The mobile telephone provides a customized menu of selectable options for initiating communication. The menu is dependent upon received presence attribute information. A calendar application can store the content of an instant messaging dialog in an appointment record. When an application accesses a stored telephone number of a party the stored instant messaging address of that party is automatically accessed and when the application accesses a stored instant messaging address of a party, the stored telephone number of that party is automatically accessed.

Abstract: A mobile telephone includes a control device, which comprises a receiver to receive an enabling signal and a controller to enable operation of the mobile telephone in dependence upon the enabling signal. An active badge transmits the enabling signal. If the telephone and the badge are separated and the mobile telephone is no longer able to receive the enabling signal, then the controller disables the mobile telephone.
