摘要： A source Centralized Unit (CU) serves User Equipment (UE) based on UE application context for a low-latency application in the UE. In the source CU, a source Application Server (AS) uses a source User Plane Function (UPF) to serve the low-latency application in the UE. In response to a handover to a target CU, the source CU indicates the source UPF to the target CU. The target AS in the target CU uses the source UPF ID to retrieve the UE application context for the UE from the source AS. In the target CU, a target AS serves the low-latency application based on the retrieved UE application context.

摘要： In a wireless network, a Distributed Unit (DU) receives Uplink (UL) data from User Equipment (UE) and a Central Unit (CU) receives Downlink (DL) data for the UE. When DL-centric applications in the UE use the DL, the CU executes most network applications and the DU executes a few network applications. When the DL-centric applications use the UL, the DU executes the network applications and the CU transfers the UL data to the core. When UL-centric applications in the UE use the DL, the CU routes the DL data to the DU, and the DU executes the network applications. When the UL-centric applications use the UL, the DU executes a few network applications and the CU executes most network applications to route the data to the core. Advantageously, the DU and the CU are optimized to process UL/DL data for a user application based on whether the user application is UL-centric or DL-centric.
