ABSTRACT:
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates to a service of a telecommunication system and a service device included in a telecommunication system realizing such a service, and a telecommunication system including such a service device.
2. Discussion of Related Art
Such a telecommunication system supporting such a service is already known in the art, e.g. from the articles ‘Universal Personal Telecommunication (UPT)—Concept and Standardisation’ of Jonas Sundborg and ‘Evolving an Intelligent Architecture for Personal Telecommunication’ of Lennart Söderberg, published in Ericsson Review number 4 in 1993, respectively from pages 140 to 155 and from pages 156 to 171 thereof.
As described on page 142 thereof universal personal telecommunication UPT enables access to telecommunication services while allowing personal mobility. It enables each UPT user to participate in a user-defined set of subscribed services and to initiate and receive a call on the basis of a personal, network-transparent UPT number across multiple networks on any fixed or mobile terminal, irrespective of geographical location, limited only by terminal and network capabilities and restrictions imposed by the network operator. A call to UPT users may also be made by non-UPT user. A universal telecommunication service will allow access from multiple networks and provide terminal independence. In principle, a UPT user may use any terminal for making and receiving UPT calls—provided that the terminal is capable of supporting the requested services. The UPT service may be accessed by UPT users across multiple networks; for example, Public Switched Telephone Network PSTN, Integrated Service Digital Network ISDN and Public Data Network PDN. Another dimension is operation over private telecommunication networks PTNs, interworking with the public network.
In particular, on page 158 of the above mentioned articles a list of user requirements in an universal personal telecommunication UPT network is described. On of the requirements is that the user wants to be able to communicate with selected persons only, which implies the ability to manage personal directories for both originating and terminating calls and to specify how each entry is to be treated.
Page 148 describes a “variable default Incall registration” which enables the UPT user to set up a default registration matrix of terminal addresses for incoming UPT calls, so that incoming UPT calls can be routed and handled differently according to time of the day, day of the week, calling party's identity, type of service, the number dialled, and according to ‘on no answer’ or ‘on busy’ conditions, as appropriate. A UPT user can modify his or her own matrix so that it fits e.g. to his or her regular travel routing or time schedule.
An obvious way to realize a service of a telecommunication network which is delivered upon receiving of a communication request of an originating user, is for instance a sequence of steps to:
check whether the originating user is allowed to make a call;
set up a connection from the originating user to the terminating user; and
check whether the terminating user is willing to accept the call, wants to forward it to another destination or reject the call.
A result of such a service is that depending on the contents of the personal directory of the originating user the communication request is dropped or later on depending on, the contents of the registration matrix of the terminating user, either the connection which is set up is completed and established or the connection which is set up is dropped.
However, a problem outstanding with this service is that in the event when the connection set up is dropped, bandwidth is temporarily allocated for a connection that will never be completed. Consequently, the network resources are not used in an optimal way.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a service of a telecommunication network which is delivered upon a communication request, such as the above known one, but which has not the above drawback of temporarily allocating bandwidth for a connection that will never be completed.
According to a first aspect of the present invention, a service supported within a telecommunication system which is delivered upon receiving a communication request of an originating user, said communication request being generated at a first terminal of said originating user and including an identification of a terminating user, is characterized in that said service includes retrieving and comparing a request profile of the originating user and reachability profile of the terminating user.
The service according to the first aspect of the present invention is further characterized in that the service further includes any or both of the steps of: (a) according to a result of said comparing, establishing a communication between a second terminal of the originating user and a first terminal of the terminating user, and (b) generating and providing information of the result to a third terminal of the originating user or to a second terminal of the terminating user. The comparison can be performed by other terminals, such as by a fourth terminal of the originating user or a third terminal of the terminating user. Or, the comparing can be performed by comparing means included in a telecommunication network which is included in the telecommunication system. Such a telecommunication system could be a universal personal telecommunication network, and the request profile and the reachability profile would therefore include universal personal telecommunication features.
The service according to the first aspect of the present invention is characterized in that the service further includes the step of generating and providing information of the result to a fifth terminal of the originating user in order to tune the request profile to the reachability profile.
The service according to the first aspect of the present invention is further characterized in that it includes the step of generating and providing information of the result to a sixth terminal of the originating user in order to design a common request profile and a common reachability profile.
According to a second aspect of the present invention, a service device included in a telecommunication system for delivering a service within the telecommunication system upon receipt of a communication request of an originating user, the communication request being generated at a first terminal of the originating user and being provided via a telecommunication network to the service device, the first terminal and the telecommunication network being included in the telecommunication system and the communication request including an identification of a terminating user, is characterized in that the service device includes retrieving and comparing means for retrieving and comparing a request profile of the originating user and a reachability profile of the terminating user.
The service device according to the second aspect of the present invention is further characterized in that the service device further includes communication establishing means included to generate a call signal upon receipt of a call result signal of the retrieving and comparing means, the call signal being provided to call setup means included in the telecommunication network in order to establish a communication according to the call result signal between a second terminal of the originating user and first terminal of the terminating user via the telecommunication network, the second terminal of the originating user and the first terminal of the terminating user being included in the telecommunication system.
In further accord with the second aspect of the present invention, the service device is further characterized in that it further includes information generating means for generating an information signal upon receipt of an information result signal of the retrieving and comparing means, the information signal being provided to informatio
