A METHOD AND NODES FOR TRANSMITTING USER CONTEXT BETWEEN COMMUNICATION NETWORKS

摘要

A method of managing a subscription request at a originating network node of a first network operator is provided, where a subscription request originating from, or on behalf of a user being a subscriber of the first network operator is provided with user context that is specifying an agreement between the first network operator and the subscriber. The subscription request is then transmitted to a terminating network node of a second network operator, with which the first network operator has established an interoperability agreement. The described procedure enables the second network operator to authorize the subscription request taking the user context into consideration, such that the interoperability agreement between the two network operators is applied for the subscriber also by the second network operator.
