  • Publication number: 20250227494
    Abstract: A computerized method manages the operations of wireless access points (WAPs) in a combined wireless network. A local controller is associated with a plurality of WAPs, and it obtains configuration data and location data from the plurality of WAPs. The local controller determines that a first WAP and a second WAP are neighbor WAPs using the configuration data and the location data, wherein neighbor WAPs have overlapping signal coverage areas. The local controller further receives network data from the first WAP and the second WAP. Network resource allocation instructions are generated for the first WAP and the second WAP using a network optimization model, the received network data, and the obtained configuration data. The generated network resource allocation instructions are distributed to the first WAP and the second WAP, whereby the first WAP and the second WAP are instructed to operate in ways that do not interfere with each other.

  • Publication number: 20250227456
    Abstract: In a communication network, a User Equipment (UE) simultaneously executes a first user application and a second user application. In response to executing the first user application, the UE requests a first network slice using a first user identity, and the communication network authorizes the first network slice for the UE based on the first identity. In response to executing the second user application, the UE requests a second network slice using a second user identity, and the communication network authorizes the second network slice for the UE based on the second identity. The UE and the communication network exchange first user data for the first user application with the first network slice, and simultaneously, the UE and the communication network exchange second user data for the second user application with the second network slice.

  • Patent number: 12342426
    Abstract: 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.

  • Patent number: 12328797
    Abstract: A wireless communication network provides a wireless communication service to a User Equipment (UE) responsive to an Application Server (AS) that is external to the wireless communication network. A Network Exposure Function (NEF) receives a Radio Access Network (RAN) instruction from the AS. The RAN instruction controls the wireless communication service for the UE. The NEF transfers the RAN instruction to the RAN. The RAN receives the RAN instruction and delivers the wireless communication service to the UE based on the RAN instruction from the AS. The RAN transfers RAN information that characterizes the RAN delivery of the wireless communication service to the UE based on the RAN instruction from the AS. The NEF receives the RAN information and transfers the RAN information to the AS that is external to the wireless communication network.

  • Publication number: 20250184390
    Abstract: A computerized method configures and uses ad hoc servers to serve content. A content server configured to serve a content dataset periodically provides a current server load notification to a domain name server (DNS). Upon detecting that a current load of the content server exceeds a server load threshold, the DNS sends a new server setup notification to the content server. The content server then identifies an ad hoc server and performs a content service handover to the identified ad hoc server. Upon completion of the content service handover, the content server provides a new server notification to the DNS indicating that the identified ad hoc server is ready to serve the content dataset. The DNS is thereby enabled to divert client requests for the content dataset to the ad hoc server during the period that the current load of the content server exceeds the server load threshold.

  • Publication number: 20250150957
    Abstract: Aspects herein provide a system, media, and methods for provisioning and establishing multiple network slices for use by an application. In aspects, a particular application is able to provision a URLLC slice and an eMBB slice from a network. Based on a predefined policy associated with the application, the application communicates high priority data using a URLLC slice and non-priority data using the eMBB slice. The application can utilize unique headers on high priority data and non-priority data to implement the data prioritization schema, which the network can further use as filters. As such, the application can leverage the distinct characteristics of URLLC and eMBB to optimize the application's performance and operations at a user device and/or within the network.

  • Patent number: 12279340
    Abstract: A wireless communication network receives a first Subscriber Identity Module (SIM) profile from a User Equipment (UE) and authenticates the UE based on the first SIM profile. The network receives a first slice request from the UE and authorizes a first wireless network slice for the UE based on the authentication of the first SIM profile and the first slice request. The network receives a second SIM profile from the UE and authenticates the UE based on the second SIM profile. The network receives a second slice request from the UE and authorizes a second wireless network slice for the UE based on the authentication of the second SIM profile and the second slice request. The network wirelessly exchanges first slice data with the UE over the first wireless network slice, and simultaneously, exchanges second slice data with the UE over the second wireless network slice.

  • Publication number: 20250081220
    Abstract: The technology disclosed herein relates to improved data transmissions over a radio access network (RAN). In embodiments, the RAN can receive, via a RAN node, a request for extended reality (XR) traffic (e.g., the request being associated with a user device). In embodiments, based on the request, one or more components of the RAN can allocate XR data for transmission over one or more ultra-reliable low latency communication (URLLC) slices that each have a latency parameter below an XR latency threshold. In embodiments, the XR latency threshold can be determined based on the request. In embodiments, one or more RAN components can identify a frequency band (e.g., associated with a RAN node) having a URLLC slice that has a latency parameter below the XR latency threshold. As such, XR data can be transmitted to the user device via the URLLC slice having the latency parameter below the XR latency threshold.

  • Publication number: 20240373286
    Abstract: Various embodiments comprise a wireless communication network to proactively notify congestion control systems in response to downlink data congestion. The wireless communication network comprises an access node and an application server. The access node wirelessly exchanges user data with a wireless user device and exchanges the user data with a network user plane for delivery to an application server. The access node detects a data queue for downlink user data transferred by the application server and received from the network user plane and indicates the data queue to the network user plane for delivery to the application server. The application server receives the indication, generates additional user data, and transfers the additional user data based on a congestion control scheme. The access node exchanges the additional user data with the network user plane for delivery to the application server and wirelessly exchanges the additional user data with the wireless user device.
