Abstract
A method and system for providing access to Quality of Service levels from within a network to entities outside of the network.
Claims14
A method for managing an ongoing data flow based on a quality of service (QoS) policy, the method comprising:
- monitoring, by a radio access network (RAN) node, an ongoing condition of radio resources of the RAN node for the on-going data flow;
- responsive to the monitoring, on condition that there is a change of the ongoing condition, determining, by the RAN node, whether a QoS parameter can be supported, the QoS parameter being associated with an effective flow bit rate for the ongoing data flow;
- on condition that the effective flow bit rate cannot be supported, informing, by the RAN node, a control plane of an inability to guarantee the effective flow bit rate;
- wherein the control plane including a network exposure interface function including interfaces for exchanging information with an external application server (AS), the method further comprising:
- determining, by the network exposure interface function, network capability information upon receiving a change notification of the change in the QoS parameter;
- and
- sending, by the network exposure interface function, the network capability information based on the received change notification to the AS;
- upon receiving the network capability information, the AS selecting a transport protocol and protocol parameters for the on-going data flow of at least one network service based on the received network capability information.

A communication system comprising:
- a radio access network (RAN) node and a control plane, wherein
- the RAN node comprises at least one processor operatively coupled to a corresponding set of memory components which include stored program instructions for execution by the at least one processor such that the RAN node is configured to:
- monitor an ongoing condition of radio resources of the RAN node for an on-going data flow,
- in response to the monitoring, determine, on condition that there is a change of the ongoing condition, whether a QoS parameter can be supported, the QoS parameter being associated with an effective flow bit rate for the ongoing data flow;
- and
- on condition that the QoS parameter cannot be supported, inform the control plane, via a first network interface enabling communications between the RAN node and the control plane, of an inability to guarantee the new QoS parameter;
- the control plane comprises at least one processor operatively coupled to a corresponding set of memory components which include stored program instructions for execution by the at least one processor such that the control plane is configured to:
- obtain information being informed by the RAN node;
- and expose such information to an application server;
- the control plane including a network exposure interface function including interfaces for exchanging information with an external application server (AS), the network exposure interface function configured for:
- determining, by the network exposure interface function, network capability information upon receiving a change notification of the change in the QoS parameter;
- and
- sending, by the network exposure interface function, the network capability information based on the received change notification to the AS;
- and the AS configured for:
- upon receiving the network capability information, the AS selecting a transport protocol and protocol parameters for the on-going data flow of at least one network service based on the received network capability information.
