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: A Long Term Evolution (LTE) access node to serve User Equipment (UEs) with a wireless Carrier Aggregation (CA) data communication service. A data processing system schedules CA Primary Component Carriers (PCCs), CA intra-band Secondary Component Carriers (SCCs) and CA inter-band SCCs for the UEs.

The data processing system detects that a number of the UEs exceeds a UE threshold, and in response, identifies the UEs that use an LTE channel for their CA inter-band SCCs but not for their CA PCCs. The data processing system disables the LTE channel for the UEs that use the LTE channel for their CA inter-band SCCs but not for their CA PCCs.
