Abstract: An aspect of the disclosure provides for a method for user equipment (UE) internet protocol (IP) address management. The method includes sending by an application function (AF), a request to a policy control function (PCF), the request including information identifying traffic and an indication that a UE IP address associated with the traffic should be preserved. The method further includes sending by the PCF, to a session management function (SMF) being responsible for managing a Protocol Data Unit (PDU) session associated with the traffic, a policy and charging control (PCC) rule including the indication. In some embodiments, the request is sent by the AF to the PCF via a network exposure function (NEF). In some embodiments, the method further includes managing, by the SMF, the UE IP address according to the PCC rule. In some embodiments, the managing includes preserving the UE IP address for a PDU session associated with the traffic. In some embodiments, the preserving includes preventing reselection of a protocol data unit (PDU) session anchor (PSA) to which the UE IP address is associated.

Abstract: Methods for quality of service monitoring, policy enforcement, and charging in a communications network, are disclosed. The methods include mapping quality of service parameters to measured parameters of a real-time video or packet data unit flow. The mapping may be used to monitor bursty traffic to adhere to quality of service requirements, perform traffic shaping, and for use in reporting certain network events. The measured parameters of real-time packet data unit flow include a first bit rate measured over a short-term measurement window and a second bit rate measured over a long-term measurement window. The short-term and long-term measurement windows are differently sized.

Abstract: Embodiments are provided herein for a system and methods for real-time video (or other real-time traffic) delivery, e.g., for cellular or wireless networks. The schemes herein address real-time video delivery by a joint design of the radio resource scheduler and the video encoder at the network side, and of the decoder at the users' terminals. The system design reduces frame loss and hence improves user quality of experience. In an embodiment, a radio node detects a frame of a real-time traffic flow. Upon determining that a transmission deadline corresponding to a rate for real-time traffic flow does not support a size of the frame, the transmission deadline is extended according to the size of the frame and a size of a next frame. The frame and the next frame are scheduled for forwarding within the extended transmission deadline.
