Abstract: System and methods for modifying streaming data based on radio frequency information is provided. As radio transceivers transition move to a shared resource or cloud model and the existing radio transceivers are split into a baseband unit and a remote radio head, radio frequency (RF) information including power levels, encoding, data rates, and bandwidth can be provided to video optimization server. The RF information can be provided more frequently to allow real-time modifications to streaming video data. Existing protocols are reactionary in nature and perceive changing channel conditions indirectly. By providing RF information from the baseband unit on a low latency channel, modifications to the video stream can be made before an impact would be noticed at the protocol level. Also, policy information can be used to influence the changes made to streaming data in addition to the RF information.

Abstract: Embodiments are directed to a virtual mobility anchor network element to receive, from a packet gateway (PGW) node, a request for an internet protocol (IP) address for a mobile device, establish an IP address for the mobile device; and provide the IP address to the PGW node in response to the request for the IP address for the mobile device. The virtual mobility anchor network element is configured to receive IP traffic from a network location; determine a target destination for the IP traffic based on a destination IP address, the destination IP address comprising the second IP address; and forward the IP traffic to the PGW node associated with the destination IP address. The virtual mobility anchor network element is also configured to receive IP traffic from the PGW node; determine a target destination for the IP traffic; and route the IP traffic to the target destination.
