Abstract: An application specific interface (AA-NAPI) associated with an application for the purpose of controlling the networking aspects of the application session is provided by communication service provider (CSP). Cost model of network service types associated with a specific application type is learned by using the AA-NAPI. For each service-point joining the session, network properties are queried by using the AA-NAPI. During continuous service quality monitoring, upon detection of quality degradation leading to the decision to upgrade session quality, network service-type associated with a specific server-point is changed by using the AA-NAPI. Network specific actions are taken to reconfigure the network so that the requested service type is received by the specific service-point. New network capability is activated to improve network service level by using the AA-NAPI.

Abstract: A metric of cell congestion is determined using an average physical resource block rate that is expected to be allocated for a very active user equipment bearer that is a persistent average rate. The average physical resource block rate is mapped to congestion levels and this information is exported to an application function or a radio access network function in order to mitigate congestion. An average bearer throughput for the user equipment can be calculated based on the average physical resource block rate.
