摘要： A method for locally serving content is described. The method includes receiving, at a gateway device, a first request for a data file via a first user device communicatively coupled to the gateway device. The data file is received at the gateway device from an external server and sent to the first user device. A data record is stored to a storage device indicating that the data file has been sent to the first user device. A second request for the data file is later received at the gateway device from a second user device communicatively coupled to the gateway device. In response to the receiving of the second request, the data record is accessed and causes a computer read of the data record. The first user device is then instructed to transfer the data file to the second user device, via the gateway device, based upon the computer read.

摘要： A method for distributing computations across a network is described. The method includes determining a computational-need condition. Then one or more used devices may be selected based at least in part on status and reporting messages, and a computational capacity of the user equipment. The user equipment is instructed to perform a computational task to meet the computational-need condition. The user equipment will send a computational result upon completion of the computational task. A node will then implement the computational result so as to at least partially meet the computational-need condition.

摘要： In a wireless data network, a Distributed Unit (DU) receives Uplink (UL) server data from server applications in wireless User Equipment (UEs). The DU processes the UL server data with an UL DU Hybrid Automatic Repeat Request (HARQ), generates UL HARQ Acknowledgements (ACKs) based on the UL server data, and transfers the UL server data to a Central Unit (CU). The CU receives the UL server data, processes the UL server data with an UL CU MAC, and transfers the UL server data. The CU receives (Downlink) DL server data for the server applications in the wireless UEs and transfers the DL server data to the DU. The DU receives the DL server data from the CU, processes the DL server data with a DL DU MAC comprising a DL DU HARQ, and transfers the DL server data and the UL HARQ ACKs to the wireless UEs.

摘要： A wireless communication device executes a low-latency application in a source wireless communication network based on application context that comprises an application user identifier, an application session identifier, and an application session pointer. A target wireless communication network detects a hand-in of the wireless communication device, and in response, obtains the application context for the wireless communication device from the source wireless communication network. The target wireless communication network wirelessly exchanges low-latency data with the wireless communication device for the low-latency application based on the application context that comprises the application user identifier, the application session identifier, and the application session pointer.

摘要： Systems and methods are provided for controlling implementation of network policies in a system including a core network and an open radio access network (O-RAN). The method includes receiving a request for accessing one of multiple network components from an application at a centralized network policy controller. The method additionally includes evaluating the request at the central network policy controller to determine if the request is core related or RAN related and assigning the application to a selected one of the multiple network components based on the evaluation, wherein the selected one is a core component when the request is core-related and the selected one is a RAN component when the request is RAN-related.

摘要： A wireless communication network serves a User Equipment (UE) over a Radio Access Network (RAN) and externally exposes RAN data. A RAN controller comprises at least one of a near-Real Time RAN Intelligent Controller (near-RT RIC) and a non-Real Time RAN Intelligent Controller (non-RT RIC). The RAN controller controls the RAN, and the RAN responsively serves the UE. The RAN controller identifies RAN data that characterizes the RAN service to the UE. The RAN controller transfer the RAN data to a Network Exposure Function (NEF). The NEF receives the RAN data from the RAN controller and exposes the RAN data to an external data system like an Application Server (AS).

摘要： In a wireless communication system, a Session Management Function (SMF) transfers signaling to a User Plane Function (UPF) to deliver a wireless data service to a wireless User Equipment (UE). The UPF exchanges user data with the wireless UE over a source Radio Unit (RU) to deliver the wireless data service. A Radio Resource Control (RRC) detects the RU handover of the wireless UE from the source RU to a target RU and transfers an RU handover notice for the wireless UE the SMF. The SMF transfers new signaling to the UPF to modify the wireless data service for the wireless UE. The UPF exchanges additional user data with the wireless UE over the target RU to deliver the modified wireless data service to the wireless UE.

摘要： A wireless communication network serves a User Equipment (UE) that executes a low-latency application. A source Application Server (AS) exchanges low-latency data with the UE over a source wireless access node based on application context for the UE. The application context for the UE comprises a user identifier, a session identifier, and a session pointer. A target AS receives a handover notice and responsively retrieves the application context for the UE from the source AS. The target AS exchanges additional low-latency data with the UE over a target wireless access node based on the application context for the UE that comprises the user identifier, the session identifier, and the session pointer.
