Abstract:
1. A communications network node configured to determine a set of policies for a terminal that is connected to a first access network so as to provide a desired quality level of data communication with the terminal using a plurality of data flows, the network node comprising: a failure indication receiver configured to receive a signal indicating that the first access network is unable to provide a desired quality level for the data communication with the terminal; an access network determiner configured, in response to the failure indication receiver receiving a signal indicating that the first access network is unable to provide the desired quality level of data communication with the terminal, to determine at least one further access network suitable for providing a data flow of the data communication with the terminal; a policy generator configured to generate a set of policies for the data communication, the set comprising a plurality of policies wherein each policy specifies one or more access networks for one or more data flows of the data communication, and at least one policy specifies the at least one further access network determined by the access network determiner for providing one or more data flows to the terminal, wherein: the policy generator is configured to generate at the least one policy in the set such that the policy includes data flow information defining whether the policy applies only to a currently established data flow, a currently established data flow and a future data flow, or only to a future data flow, and the policy generator is configured to include the data flow information in the at least one policy by providing a flag therefor in an Access Network Discovery and Selection Function, ANDSF, Management Object; and a policy provider configured to provide the generated set of policies to the terminal.
