Method, device and system for selecting a wireless access network on the basis of environment information, computer program and corresponding data support

A telecommunication system comprising

• at least two terminals,
• a set of at least two wireless access telecommunications networks forming an infrastructure of networks capable of providing an overall link between a first terminal and a second terminal,
• wherein said telecommunication system is configured to:
• supply context information relating to a set of at least one context terminal taken from the first and second terminals,
• select a chosen network among said set of at least two wireless access telecommunications networks, from the context information of the set of context terminals by following a predetermined set of rules, wherein the context information of at least one reference terminal is taken from the set of context terminals comprising information relating to a local environment of the at least one reference terminal, wherein the local environment of the at least one reference terminal is a set of terminals effectively connected to the at least one reference terminal independently of the infrastructure, and wherein said selecting the chosen network depends on the information relating to the local environment of the at least one reference terminal, and
• provide an overall link between said first and second terminals, by using said chosen network.

A non-transitory computer readable medium comprising program code instructions for the execution of a method on a computer, wherein said method is utilized in a telecommunications system comprising at least two terminals and a set of at least two wireless access telecommunications networks forming an infrastructure of networks capable of providing an overall link between a first terminal and a second terminal and wherein said method comprises:

• supplying context information relating to a set of at least one context terminal taken from the first and second terminals,
• selecting a chosen network among said set of at least two wireless access telecommunications networks, from the context information of the set of context terminals by following a predetermined set of rules,
• the context information of at least one reference terminal taken from the set of context terminals comprising information relating to a local environment of the at least one reference terminal,
• the local environment of the at least one reference terminal being a set of terminals effectively connected to the at least one reference terminal independently of the infrastructure, and
• said selecting the chosen network depending on the information relating to the local environment of the at least one reference terminal, and
• providing an overall link between said first and second terminals, by using said chosen network.

A device for selecting a wireless access telecommunications network for terminals from a set of at least two wireless access telecommunications networks forming an infrastructure of networks , the device comprising, for providing a link between a first terminal and a second terminal:

• means of supplying contextual information, arranged to supply context information relating to a set of at least one context terminal;
• means of selecting a chosen wireless access telecommunications network, arranged to determine a network among said at least two wireless access telecommunications networks, from the context information by following a set of predetermined rules,
• the context information of at least one reference terminal taken from the set of context terminals comprising information relating to a local environment of the at least one reference terminal, the local environment of the at least one reference terminal being a set of terminals effectively connected to the at least one reference terminal independently of the infrastructure,
• the means of determining the network being moreover arranged in order to determine the chosen network according to the information relating to the local environment of the at least one reference terminal, the chosen network providing an overall link between said first and second terminals.
