ABSTRACT:
TECHNICAL FIELD
The present invention relates generally to the field of communication services which are performed through selected telecommunication networks. The invention relates in particular to a person paging method.
The present invention is related to the following five patent applications, to which the following description refers:
1) “A Method of Establishing an Intelligent Network Service”, with Applicant's reference LM 5515.
2) “A Method of Establishing a Connection”, with Applicant's reference LM 5516;
3) “A Method of Organizing Communication”, with Applicant's reference LM 5517.
4) “A Method of Establishing Cooperation with a Functionality”, with Applicant's reference LM 5518; and
5) “A Method of Supporting Communication”, with Applicant's reference LM 5520;
These applications are enclosed as an annex to the present description and describe mechanisms which can be used in the method according to the present invention.
TECHNICAL BACKGROUND ART
By communication services is meant conventional telephony services, telex services, datapack services, datel services, telefax services, videotext services, ISDN-services, mobile telephony services, personal paging services, tele-point-services and general communication between two or more parties. The services recited above are only examples of the services possible and are not intended to limit the scope of the invention.
By telecommunication network is normally meant the telephone networks, telex networks, circuit connected data networks, picture information transfer networks, private telecommunication networks, radio networks, satellite communication networks and general carriers of the communication services, such as analog transmission, digital transmission, synchronous, multiplex or asynchronous multiplex transmission, ATM, etc., for example. These networks are recited solely by way of example and the invention is not restricted thereto.
By functionality is meant the ability to perform an operation in a telecommunication network. Examples of functionality include activities and services that can be performed in the telecommunication network. Examples of functionalities include an enquiry to establish a connection path or route between two parties, digit analysis, billing or ticketing. Although not necessary, the functionality may require the availability of dedicated equipment for carrying out the functionality. For instance, if the functionality is to receive tones and to analyze tones, it is necessary to make a tone receiver accessible. Other examples of functionalities include voice-controlled speech information, number translation service, conference calls. Other examples of functionality include the functionalities described in the aforesaid five Swedish patent applications, namely communication in the form of a meeting, personal paging, a method of establishing cooperation with a functionality, meeting connection establishment and communication via intermediaries. Still another example of functionality is the ability of being able to choose from among several alternatives.
By connection is meant a circuit-coupled connection or a package-coupled connection. By to establish a connection is meant in the circuit coupled case that a circuit-coupled connection is established between two hardware terminal devices (or equipment) and in the package coupled case it is meant that a package-coupled connection creates relationships between logic channels on node-interconnecting physical links which. By to originate or to terminate a connection, it is meant in the circuit-coupled case to connect originating or terminating equipment to a circuit-coupled connection, and in the package-coupled case to create a session between applications in originating and terminating nodes respectively.
By user is meant in the following a human user or a computer-based application which utilizes communication services. The application may be achieved with hardware, software and combinations thereof. The word “part” is synonymous to the term user.
By terminal is meant equipment which is connected to a telecommunication network and which makes the telecommunication services of the network available to a user.
The term port either refers to an access port or to a transit port. An access port is a location where a dedicated terminal is connected to a telecommunication network. An access port is associated with a destination address which goes to an end user. In the case of a standard telephone network, the access ports are located in a telephone station. In the case of the ISDN-network and the mobile telephone network, the access ports are found in a terminal. A transit port is a port in a connection between nodes. A transit port is not associated with any particular destination address, and can be used to establish any selected connection with a final destination. The final destination is given by the destination address. A transit port can transfer a call to another node or can receive a call from another node.
The final destination of a call is a terminal which is identified by a destination identity. The terminal can be present in the same node as a transit port or in some other node to which the call shall be further connected.
One fundamental feature of present-day communication services is that when a party, hereinafter called A, wishes to communicate with another party, hereinafter called B, A sends a call to B, whereupon a connection is established between A and B. The call and the establishment of a connection route is a coupled sequence. By this is meant that the information which A uses in the call, namely information relating to the identification of B's access point in the telecommunication network, causes a connection route, or path, to be established between the parties. This connection can either be circuit-coupled or, in the case of non-continuous transmission methods, a so-called virtual connection, e.g. a package-coupled network, ATM-network (asynchronous transfer mode), etc. Traditionally, a connection is established by establishing a route from an origin to a destination. The connection route through the telecommunication network is controlled by fixed, so-called routing tables which are drawn up when configuring or reconfiguring the network. The routing tables may sometimes permit alternative selections, based on local accessibility information.
The traditional communication network is encumbered with many drawbacks. A first problem concerns handling of the resources of the communication network. Firstly, the communication network is, in itself, a resource which is utilized uneconomically in the traditional method of providing communication services. For example, when party A calls party B, so as to establish a connection through the network from A to B, and party B does not accept the call, the network resources have been used unnecessarily. The same applies when party B is engaged. The case is dependent on the predominant use of present-day networks of channel-associated signalling. This involves establishing a signalling connection, which is then used for speech purposes. With common channel-signalling, which is used primarily in the long-distance network, the signal connection is established with the aid of the data package, or packet, whereas the speech connection, the expensive part of the communication, is not established until B answers. Common channel-signalling is scarcely used in local networks. Secondly, the majority of all established connections do not require party B to act immediately on the information that A will transfer.
In the aforesaid cases, the network resources are either used unnecessarily or are utilized in real time, although it would be possible to utilize the resources at a later time.
Neither do present-day telecommunication services enable a party A to call a party B on a telecommunication network and establish communication with party B on another telecommunication network different to the first-mentioned network. If B has access points in several telecommunicati
