  • Publication number: 20240137748
    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.

  • Patent number: 11962641
    Abstract: 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.

  • Patent number: 11877349
    Abstract: User circuitry within a wireless User Equipment (“UE”) that may utilize multiple subscriber identity module (“SIM”) profiles activates two or more SIM profiles to be active simultaneously. The user circuitry transfers service requests for wireless data services using the SIM profiles to network circuitry. The wireless data services may have different slice service types over different operating frequency bands of different target cells. The network circuitry wirelessly exchanges data with wireless access nodes associated with the target cells over the operating frequency bands to establish packet data unit sessions comprising the slice service types using the respective SIM profiles such that multiple packet data unit sessions are active using multiple SIM profiles simultaneously. Various applications may be mapped to the appropriate SIM profile and packet data unit session based on the respective provisioned slice characteristics matching the respective application requirements.

  • Patent number: 11870733
    Abstract: Methods are provided for dynamically deactivating and reactivating a radio at a particular cell site based on a detected radar signal. When a cell site detects a radar signal, it sends a radar signal alert (RSA) broadcast to its neighboring cells in the direction the radar signal is traveling. The cell site receiving the RSA broadcast is able to determine, based on locations and time stamps of two or more cell sites providing the RSA broadcast, the direction the radar is sweeping, the speed of the radar signal, and the time the radar signal will reach its site. Based on this determination, the cell site can determine the appropriate time to shutoff the Band 41 radio as well as the appropriate time to power on the Band 41 radio. Moreover, the cell site may initially reduce power to the Band 41 radio to reduce the shutoff time.

  • Publication number: 20230403551
    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.
