Abstract: A new function is added into switching centres (CPS) to facilitate the adding of various services, the function transmitting the service data structure of a non-standard service to a system entity responsible for the service. The system entity is identified on the basis of an indicator associated with the service data structure.

Abstract: A communications system and method for providing services to a subscriber of the system is provided. The system includes a system element controlling call processing, service data for a subscriber of the system, and an element for storing subscriber data. The system is configured to associate an indicator with a service data structure of the service data of a subscriber. The element for storing subscriber data is configured to store the service data structure of the service data of the subscriber associated with the indicator. The system is configured to transmit from the element for storing subscriber data service data of a subscriber comprising the service data structure associated with the indicator to the system element controlling call processing service.

Abstract: This invention relates to a communication system comprising a least one user with which presence information is associated, said presence information comprising a plurality of parts, at least one of said parts comprising information identifying an application for which said at least one part is intended; and at least one entity to which presence information associated with said at least one user is provided, said at least one entity having at least one entity application, said at least one entity being arranged to use said information to obtain the at least one part intended for said at least one entity application.

Abstract: This invention relates to a communication system comprising a plurality of users with which presence information is associated, said presence information comprising a plurality of parts; means for storing information defining at least one group, said group containing a plurality of users, and means for providing information defining for said at least one user of said group what parts of said presence information are to be provided.

Abstract: A method and entity of authorising in a communication system are disclosed. The method includes using authorising data to reference other data to define an authorisation associated with the other data. The authorising data includes one of a data component, data group, or data element. Further, a user profile can be provided and includes a user profile data component and an authorisation data component. The authorisation data component or the user profile data component references another authorisation component. Access is authorised to data associated with the user profile data component in accordance with the authorisation data component.

Abstract: A computer-implemented apparatus and method for communicating partial notifications relating to a presentity's presence information. The communication may be effected between presence servers and terminals coupled to the presence servers via a network. At least one presentity is identified to which a terminal has requested presence services. A presence document is created, where the presence document includes presence information corresponding to the presentity. The presence information is configured as partial presence information comprising less than a total of the presence information available for the presentity. The presence document having the partial presence information is communicated to the terminal requesting the presence information.

Abstract: A method and apparatus for updating authorization and other persistent data using the session initiation protocol. In one aspect, a computing device sends a SIP PUBLISH message (or any other appropriate SIP message) to a second networked computing device. The second device extracts data from the SIP message and uses the extracted data to modify and/or update a set of persistent data. The data may be placed in the body of the SIP message. In one example, the SIP message body uses XML enclosing a remote procedure call or a call processing script.

Abstract: A system and method for communicating partial notifications relating to a presentity's presence information. The communication may be effected between presence servers and terminals coupled to the presence servers via a network. At least one presentity is identified to which a terminal has requested presence services. A presence document is created, where the presence document includes presence information corresponding to the presentity. The presence information is configured as partial presence information comprising less than a total of the presence information available for the presentity. The presence document having the partial presence information is communicated to the terminal requesting the presence information.

Abstract: A method of accessing presence information includes receiving a summary of the presence information available, and determining desired presence information from the available presence information. In dependence on the determining step, transmitting a request for the selected presence information.

Abstract: In a communication network including at least one user associated with a plurality of terminals, a method of administering information associated with at least one user and/or the plurality of terminals, the method comprising: transmitting to a server a first message from a first terminal of the at least one user, the first message comprising message information and an identifier of the first terminal; and transmitting a second message including at least part of said message information from the server to at least one of only the other terminals of the user.

Abstract: A new function is added into switching centres (CPS) to facilitate the adding of various services, the function transmitting the service data structure of a non-standard service to a system entity responsible for the service. The system entity is identified on the basis of an indicator associated with the service data structure.

Abstract: The invention proposes a method for establishing a connection between two communication terminals, comprising the steps of receiving a request for establishing a connection from a first communication terminal (TA) to a second communication terminal (TB), checking whether the second communication terminal (TB) is roaming in a second network (N2), and in case the second communication terminal (TB) is roaming, informing the first communication terminal (A) that the second communication terminal (TB) is roaming in the second network and allowing the user of the first communication terminal (TA) to select between different options how the call is to be handled, and controlling the establishment of a connection between the two communication terminals according to the selection of the user of the first communication terminal (TA). The invention also proposes a method in which the called, i.e., the second communication terminal has the possibility to select different options to handle a call.

Abstract: The invention relates to a communication method and system wherein a network element of a roaming user is attachable to a visited first network and may still be served by a serving means of the home network. The network element of the roaming user is able to indicate a preference, e.g. home or local control, when registering or initiating a connection. A network element of the visited network such as proxy means adds information on the indicated preference when sending a message to the home network. The message is preferably sent as a protocol message, in particular a message of the Session Initiation Protocol (SIP).
