    Abstract: Embodiments include apparatuses, methods, and systems that may be used in a UE or a base station in a mobile communication network. A processing circuitry may receive, from the UE, a request for a network connection to a content server, where the request for the network connection may include a request for a transport layer connection between the UE and the content server. The processing circuitry may establish a transport layer connection between the base station and the content server based on the request for the transport layer connection between the UE and the content server. The processing circuitry may further fetch at least a portion of data from the content server and store the portion of the data in a storage device before a physical channel between the base station and the UE is available.

  • Patent number: 10716096
    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.

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.

  • Publication number: 20200220810
    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.

  • Publication number: 20190364456
    Abstract: A traffic offloading function (TOF) of a mobile edge computing (MEC) platform uses a traffic forwarding table and a location database updated by monitoring control plane messages. User plane traffic in a default bearer passes through an extended TOF where the IP packets retrieved from a General Packet Radio Service Tunneling Protocol (GTP) tunnel are forwarded following a policy that is created by detecting (or sniffing) control plane messages exchanged over the S1-MME interface. An additional entity, a location database, is responsible for tracking a location of a UE and other hosts in the mobile network. The location database can be used to guide the forwarding policy creation in an absence of the control plane messages.
