A method of indicating the IP Multimedia Subsystem communication service(s) to which a Session Initiation Protocol message relates, the method comprising including one or more communication service identifier(s) in the Session Initiation Protocol message as a Feature Tag of the message.

Method and apparatus for identifying an IMS service

A method of indicating IP Multimedia Subsystem (IMS) services and IMS applications to which a Session Initiation Protocol (SIP) message relates. An IMS communication service identifier and an IMS application reference are added to the SIP message. The identifier and the reference may be added as Feature Tags. The reference may also be added as an a-line augmenting an m-line in a Session Description Protocol (SDP) part of the SIP message.

A User Equipment (UE) and IP Multimedia Subsystem (IMS) network node for indicating the IMS services and IMS applications to which a Session Initiation Protocol (SIP) message relates. An IMS communication service identifier and an IMS application reference are added to the SIP message. The identifier and the reference may be added as Feature Tags. The reference may also be added as an a-line augmenting an m-line in a Session Description Protocol (SDP) part of the SIP message.

The invention relates to a telecommunication system provided with resources and with software which controls the individual resources and also the manner in which the resources cooperate mutually at a system level. In accordance with the invention, the software is divided into two parts. The first part, called object logic, comprises a number of object units, each of which represents an individual type of resource. Further, each object unit includes operations for controlling its individual resource. An individual type of resource may be used for a number of different purposes. The second part, called control logic, includes a number of control cases. Each control case, in turn, combines a number of object units in a superordinate fashion, to control the mutual cooperation of corresponding resources irrespective of the manner in which an individual object unit is intended to influence its resource. A control case includes a number of control stages, each of which has only one input, at least a first operation, called control stage operation, and at least one output. The control stages of a control case are mutually connected by links, each of which is designed to connect an output of a preceding control stage with the input of a following control stage. The points at which links are connected to the control stages are called potential connection points to which additional control cases, called control case features, can be connected to the control case in which the control stages are present, called the basic control case, for modification of the basic control case.

Software program structure and method for modulizing the operations of a

A network structure and a signalling protocol for a telecommunication network. The nodes of the communication network are interconnected by a connection network as well as a signalling network. Computer software controlling the communication equipment of each node is divided into two types of software, connection related software and service related software. Connection related software groups of different nodes communicate with each other via a first protocol while service related software groups of different nodes communicate via a second protocol different from the first protocol. Between an originating node of a call and the terminating node of the same call a direct signalling path is established in the signalling network allowing for the addition of new service features in the originating and terminating nodes without the need to implement the new service features in the inbetween nodes via which the same call is routed in the connection network. A general signalling protocol supports the addition of new service features to existing nodes as well as the execution and management of the new services and the services already existing in the telecommunication network. The signalling protocol is divided into a basic protocol and one or more service specific protocols called dialogues. The basic protocol is used to establish a signalling path between service related software groups in the originating and terminating nodes and to establish dialogues along the signalling path. This allows for a modular addition/removal of dialogues to the basic protocol which remains unchanged.

Network structure and a signalling protocol for a telecommunication

in a telecommunication network structure, all functions related to traffic control, including functions for controlling, originating and terminating connections, take place in a mobile service control point while the physical set up of the connections take place in mobile service points which are subordinated to the mobile service control point. Subordinated units are connected to each mobile service point with trunks. A signal net is transferring traffic control signals, including connection control signals, to the subordinated units in which the connections are made, using the trunks.

Mobile telephone network structure

A building module for a ceiling having heating elements incorporated therein. The module has the form of a closed unit which can be individually mounted and removed and which comprises a frame and plates arranged on two opposite sides thereof. Heat-emitting elements are protectively arranged in the space defined by said frame and said plates and element connecting means are accessible from outside the unit and are arranged, when a unit is mounted together with other similar units to permit the elements to be connected to the intended supply source via other units located between the source and said one unit. The unit is so constructed that when mounting the same in position adjacent a similar unit there is formed a downwardly open channel between the units which channel is intended to be closed by means of a separate cover member.
