摘要： Techniques associated with localizing data traffic for a time sensitive network within a virtualized radio access network are provided. In one embodiment, a method includes determining that a user equipment (UE) is associated with a time sensitive network; and localizing data traffic for the UE within a virtualized radio access network based on determining that the data traffic for the UE can be localized at one centralized user plane component of the virtualized radio access network for the time sensitive network. The data traffic can be Layer-2 data traffic or unstructured data traffic.

摘要： The present disclosure is directed at systems, methods and media for relieving RAN congestion in a core network. In some embodiments, RAN congestion information is reported from user equipment to a packet data gateway (PGW) through an eNodeB and a software gateway. The PGW can aggregate the RAN congestion information and periodically notify other network nodes, for example, a PCRF, about the aggregate congestion in a network. By aggregating RAN congestion information, the PGW can substantially reduce the signaling required to report RAN congestion in the core network.

The methods include receiving, at a gateway from an evolved Node B (eNodeB), an attach request for a user equipment (UE), and determining a network selection hint corresponding to the received attach request, where the network selection hint is used for determining a virtual network node for selection in a mobile cloud network. The methods further include determining a domain name for establishing a network connection based at least in part on the network selection hint, where the selected domain name is associated with a virtual network node in the mobile cloud network. The methods also include selecting a virtual network node associated with the determined domain name, and establishing a network session to the selected virtual network node.

摘要： A method for location reporting at a charging area level granularity is provided. The method includes detecting at a mobility management entity (MME) a transition of a user equipment (UE) from a first cell to a second cell to obtain at least a second cell identifier. The method also includes determining at the MME whether the detected UE transition constitutes a transition from a first charging area to a second charging area using the second cell identifier by comparing the second cell identifier to a charging area configuration. A charging area includes a plurality of cells that are served by at least one eNodeB. The method further includes providing to a policy server a report of the determined UE transition, if it is determined that the detected UE transition constitutes a transition from the first charging area to the second charging area.
