Patent ID: 8412202

Claim:
A method for accessing a service from a user's terminal via a heterogeneous network in which several types of access are available, comprising the following steps: upon reception of a request for accessing the service, of a list of identifiers of accesses visible from the user terminal and of criteria for selecting and ranking the identifiers of accesses visible from the user terminal, sent by the user terminal, selection, by an access-selection server of an access of the heterogeneous network for the user terminal, said access-selection step comprising a step of reserving resources from the selected access; and sending by the access-selection server of a selected access identifier to the user terminal; wherein the access-selection step further comprises a step of ranking the list of the access identifiers provided by the user terminal on the basis of information provided by the user terminal and dynamic information obtained by learning concerning the characteristics of previous access requests provided by a local database; wherein the access-selection step further comprises: negotiating resources from a network access belonging to a list of identifiers of accesses visible from the user terminal; when negotiation with said access fails, negotiating with another access from the list and updating the ranked list of identifiers after each negotiation of resources; and when negotiation with all the accesses from the list fails, selecting the access leading to the best negotiation result based on the updated list of the access identifiers.
