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 method for routing traffic between a source node and a destination node in a network comprises: identifying a first group level at which a source group vector and a destination group vector differ; obtaining one or more first route segments between a first source group and a first destination group at the first group level; computing an end-to-end route between the source node and the destination node based on at least the one or more first route segments; and routing traffic between the source node and the destination node on the end-to-end route.

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.

Abstract: A mechanism to export user equipment (UE) and/or bearer state information from a E-UTRAN Node B (eNB) mobility management entity (MME) and combine this state information with globally recognizable identifiers for the UE and/or bearer. The state information is collected by an external server and provided to application service providers (ASPs) and wireless service providers (WSP) to more effectively deliver content to the UE by adjusting throughput. The mechanism involves only a single query to the MME, for every UE and/or bearer, as opposed to one inquiry for every state information update on a per UE and/or per bearer basis, in order to not overwhelm network traffic.
