Publication number: 20220021607Abstract: 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 pane gateway (GW-C) is 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.

Patent number: 11089511Abstract: 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.Type: GrantFiled: March 16, 2017Date of Patent: August 10, 2021Assignee: APPLE INC.Inventor: Yifan Yu
