Abstract
A communication network for transporting calls, where a service provision entity adds user identification information to call data of a call being set up by a non-dialable virtual subscription such that the subscriber behind the call being set up by the non-dialable virtual subscription may be identified at the network switching layer. This increases the manageability of the network and provides advantages for call interception.
Claims43
A communication network for transporting calls, comprising:
- a plurality of switching nodes, each switching node containing routing means for routing calls through said communication network;
- service provision means fox providing predetermined services in said communication network, where at least a part of said service provision means is provided in at least one of said plurality of switching nodes, said service provision means being arranged to provide at least one service according to which said service provision means are able to set up calls in said at least one switching node in response to the request of a virtual subscriber requesting that a call be set up in accordance with a non-dialable virtual subscription, and said service provision means being arranged to add virtual subscriber identification information to the call data of a call set up by said service provision means for allowing interception of said call.
A method of arranging a service provision means providing predetermined services in a communications network for transporting calls, said communication network having a plurality of switching nodes, each switching node containing routing means for routing calls through said communication network, said method comprising;
- providing at least a part of said service provision means in at least one of said plurality of switching nodes,
- arranging said service provision means to provide at least one service according to which said service provision means are able to set up calls in said at least one switching node in response to the request of a virtual subscriber requesting that a call be set up in accordance with a non-dialable virtual subscription, and
- arranging said service provision means to add virtual subscriber identification information to the call data of a call set up by said service provision means for allowing interception of said call.
A communication network for transporting calls, comprising:
- a plurality of switching nodes, each switching node containing routing means for routing calls through said communication network;
- service provision means for providing predetermined services in said communication network, said service provision means comprising a service data means in which user data associated with users of provided services and service data associated with provided services are stored, said service provision means being arranged such that a user has access to at least a part of the user data associated with him and may change said user data to which he has access,
- wherein said service provision means are arranged;
- to provide a monitoring agency continuous access to user data of selected users, or to perform a user data change interception operation in response to a user changing his user data, and
- to provide at least one service according to which said service provision means are able to set up calls in said at least one switching node in response to the request of a virtual subscriber requesting that a call be set up in accordance with a non-dialable virtual subscription.
Apparatus for use in a communication network including a plurality of switching nodes for transporting calls and for providing predetermined services, each switching node including a router for routing calls through said communication network, the apparatus comprising:
- electronic circuitry configured to assist in setting up a call in one of the switching nodes in response to a virtual subscriber requesting that a call be set up and to add virtual subscriber identification information to call data of the set up call,
- wherein the virtual subscriber has a non-dialable type virtual subscription that is not associated with an access point to the communication network and which permits only incoming calls addressed to the virtual subscriber, and wherein the call is associated with the virtual subscription.
A method of providing predetermined services in a communication network for transporting calls, said communication network having a plurality of switching nodes, each switching node containing a router for routing calls through said communication network, said method comprising:
- providing a communications service to set up a call in at least one switching node in response to a request of a virtual subscriber for service, and
- adding virtual subscriber identification information to the call data of the set up calls,
- wherein the virtual subscriber has a non-dialable type virtual subscription that is not associated with an access point to the communication network and which permits only incoming calls addressed to the virtual subscriber, and wherein the call is associated with the virtual subscription.
