Abstract: Techniques for a selection or reselection a user-plane path in a mobile network are disclosed herein. A user-plane gateway (GW-U) can be configured to decode a packet received from a control plane gateway (GW-C) in a packet data network gateway (PGW) to determine a forwarding policy. Additionally, the GW-U can decode, from an evolved node B (eNB), an internet protocol (IP) packet having a header field. Furthermore, the GW-U can determine a user-plane path for the IP packet based on a comparison of the header field and the forwarding policy. Based on the determined user-plane path, the GW-U can forward the IP packet to a local application server (AS), encapsulate and forward the IP packet to the PGW, or discard the IP packet. Moreover, the GW-U can encode the IP packet for transmission based on the determined user-plane selection.

Abstract: Embodiments described herein relate generally to efficient transmission of data over a radio network between a user equipment (“UE”) and a network node. The UE may adapt packets from TCP to a private protocol and transmit those data packets to the network node. The UE may use ARQ data from link layer circuitry to locally generate TCP ACK data for TCP layer circuitry. At the network node, the private-protocol data packets may be adapted to TCP and transmitted to a remote host over the Internet so that the TCP semantic may be maintained between the UE and the remote host. Other embodiments may be described and/or claimed.

Abstract: Technologies for mobile content delivery include an edge computing device, a mobile terminal, and a content delivery network server. The edge computing device has a network location between the mobile terminal and a core network, and the content delivery network server is accessed through the core network. The edge computing device receives a content request from the mobile terminal and modifies the content request to identify the network location of a zone-specific proxy of the edge computing device. The edge computing device forwards the content response to the content delivery network server. The content delivery network server may send a content response to the zone-specific proxy or the mobile terminal. The content response identifies an address of a network content resource. The network content resource is located at a surrogate content delivery network server of the edge computing device. Other embodiments are described and claimed.

Abstract: An apparatus of a Next Generation Node-B (gNB) with a CP-UP separation includes processing circuitry configured to decode a radio resource control (RRC) request message from the UE for establishing a connection between the UE and a UPF of a 5G NR architecture in a network slice. In response to a confirmation message that the UE is authorized to communicate via the network slice, encode a Central Unit User plane (CU-UP) resource status request message for transmission by a Central Unit Control Plane (CU-CP) entity of the gNB to a plurality of CU-UP entities. A CU-UP resource status response message from each of the plurality of CU-UP entities is decoded at the CU-CP entity. The resource status response message including resource availability information for the CU-UP entities. A CU-UP entity is selected by the CU-CP entity from the plurality of CU-UP entities based on the resource availability information.

Abstract: There is disclosed example techniques to include obtaining a filtering rule via a control plane message that includes information to identify a source of a general packet radio service (GPRS) tunneling protocol (GTP) user-plane (GTP-U) packet. The example techniques also include configuring, based on the information to identify the source, a virtual switch to identify the source of the GTP-U packet to use in the filtering rule to cause a received GTP-U packet to be sent to a local edge server or a mobile core network for processing based on at least a portion of a first extension header included in the GTP-U packet.
