Method for providing telecommunications services, related system and information technology product

The method as recited in any of the previous claims, characterised in that the selecting step is carried out by selecting said systems in the group formed by the mobile communication systems.

The method as recited in any of the previous claims, characterise in that it comprises the step of verifying the availability of said first system 4WLAN) on the basis of a criterion of admission control of the users, by detecting the performance degradation of said first system as the number of users increases.

The method as recited in any of the previous claims, characterised in that it comprises the step of detecting the availability of said second system (UMTS), by defining a load parameter (T) of said second system and by considering said second system as unavailable when said load parameter reaches a threshold value.

A system for providing telecommunications services in an environment wherein a plurality of telecommunications systems are provided that operate according to different standards (WLAN, UMTS) and that may be accessed from a terminal (T) in an integrated manner, in which at least one of said services is deliverable by more telecommunications systems of said plurality, the system being characterised in that it incorporates a module (10) capable, when there is a provision request for said at least one service, of co-operating with said plurality of telecommunications systems with the aim of:

• verifying the availability for the provision of the service requested, of at least a first (WLAN) and a second (UMTS) system of said plurality of telecommunications systems, and
• selecting, in an automatic and dynamic way, between said telecommunications systems said at least a first (WLAN) and a second (UMTS) system of said plurality for the provision of the service requested.
