First Claim
Patent Images
1. A method comprising:
- receiving a first list of identifiers corresponding to a plurality of user terminals with which a conference call is to be established;
determining, by a control device, that at least one identifier represents a second list comprising a plurality of other user terminals each having their own other identifiers;
retrieving the other identifiers from the second list;
establishing the conference call, in a communication network, with the plurality of user terminals in the first list and the plurality of other user terminals represented by the at least one identifier in the first list; and
allowing the user terminals corresponding to identifiers from the first and second lists to participate in the conference call if the identifiers are on an access control list.

Abstract
A method of establishing a conference call in a communication network between a plurality of user terminals each having an identifier. The method comprising receiving a first list of identifiers corresponding to the user terminals with whom the conference call is to be established. At least one of the identifiers represents a second list comprising a plurality of other user terminals each having their own other identifiers. The conference call is established with the user terminals in the first list and the other user terminals represented by the at least one identifier in the first list.

14. A control device, comprising:
-
a first storage location configured to store a first list of identifiers corresponding to a plurality of user terminals with which a conference call is to be established; circuitry configured to determine that at least one identifier in the first storage location represents a second list comprising a plurality of other user terminals each having their own identifiers; and circuitry configured to resolve the at least one identifier which represents the plurality of other user terminals, allowing the user terminals corresponding to identifiers from the first and second lists to participate in the conference call if the identifiers are on an access control list and including the plurality of other user terminals in the conference call to be established, wherein the control device is configured to establish the conference call between the plurality of terminals of a communication network. - View Dependent Claims (15, 16)

17. A control device comprising:
-
receiving means for receiving a first list of identifiers corresponding to a plurality of user terminals with which a conference call is to be established; determining means for determining that at least one identifier represents a second list comprising a plurality of other user terminals each having their own other identifiers; retrieving means for retrieving the other identifiers from the second list; and establishing means for establishing the conference call, in a communication network, with the plurality of user terminals in the first list and the plurality of other user terminals represented by the at least one identifier in the first list and allowing the user terminals corresponding to identifiers from the first and second lists to participate in the conference call if the identifiers are on an access control list.

18. A communications network comprising:
-
a plurality of user terminals; and a control device configured to establish a conference call between the plurality of user terminals, each of the user terminals having an identifier and wherein the control device comprises a first storage location configured to store a first line of the identifiers corresponding to the user terminals with whom the conference call is to be established; circuitry configured to determine that at least one of the identifiers in the first storage location represents a second list comprising a plurality of other user terminals each having their own identifiers; and circuitry configured to resolve the at least one identifier which represents the plurality of other user terminals, allowing user terminals corresponding to the identifiers from the first and second lists to participate in the conference call if the identifiers are on an access control list and including those other user terminals in the conference call to be established.
