  • Publication number: 20240172073
    Abstract: The disclosed technology is directed towards preventing a handover of a Wi-Fi call to a Fifth Generation (5G) standalone cellular network. In one alternative, a 5G standalone usage setting is disabled on a mobile device when Wi-Fi calling is enabled on the mobile device. In another alternative, a 5G standalone usage setting is disabled on a mobile device when Wi-Fi calling is enabled on the mobile device and the mobile device is connected to a Wi-Fi network, which facilitates camping on a 5G standalone network when the mobile device is not connected to a Wi-Fi network. In yet another alternative, a 5G standalone usage setting is disabled on a mobile device when an evolved packet data gateway (ePDG) tunnel is set up on the mobile device, which similarly facilitates camping on a 5G standalone network when the ePDG tunnel is torn down.

  • Patent number: 10966133
    Abstract: The described technology is generally directed towards enabling user equipment to perform route selection across multiple mobile communication technologies. User equipment route selection allows specifying, by the user equipment, information which affects the way the user equipment's network communications are handled by a communication network. User equipment route selection across multiple mobile communication technologies enables certain route selection capabilities whether the user equipment is connected to a 5G Core network mobile communication technology, a 5G Option 3× network mobile communication technology, or a LTE network mobile communication technology.

  • Patent number: 8917735
    Abstract: A soft AP module that is installed in the subscriber device is adapted to assign preselected ports numbers as part of its network address translation process. Those port numbers are registered to be used solely for this purpose, port numbers that are registered to applications that are seldomly used, or port numbers in the range 49152-65535. One or more modules in the service provider's facilities analyze the packets that pass through the service provider's facilities. Each module detects the aforementioned predetermined port numbers in the analyzed packets and thus identifies the network load that is attributed to devices the employ the W2LANs.

  • Patent number: 8358647
    Abstract: A system and method for allowing legacy circuit switched user equipment (CS UE) to operate via a packet-switch system, such as an IP Multimedia Subsystem (IMS) system, is provided. The mobility and session control aspects of communications with a legacy CS UE is separated. A user agent is placed in the receiving node (e.g., a home node B) that acts as the SIP agent for the CS UE for session control. An interworking function is provided to allow mobility between the macro CS network and the PS (e.g., IMS) network.

  • Publication number: 20100120409
    Abstract: A system and method for activating a subscriber identification module (SIM) based mobile device in a PCS/ANSI type wireless network. The method comprises pre-programming the SIM card of the mobile device with temporary activation identifiers, such as an international mobile station identity (IMSI) and/or a mobile identification number (MIN), and a temporary electronic serial number. The temporary electronic serial number, rather than the mobile device actual electronic serial number, is used to identify the mobile device during registration and activation. The network identifies the temporary electronic serial number associated with the SIM vendor and invokes an over-the-air activation procedure especially for the SIM card mobile devices. A SIM-over-the-air-activation processor is notified to perform the activation for that mobile device on the PCS wireless network.

  • Publication number: 20040203800
    Abstract: A system and method for allowing a mobile telephone or mobile terminal to interact with its wireless telephone/data service, including conventional 2G and 3G systems (hereinafter the “wireless network”), and also to interact with local-area services such as WLAN, BlueTooth, and personal area networks, and to communicate with and use systems and peripherals available on those networks. Since the mobile terminal is a trusted device on the wireless network, it also then acts as a gateway to allow other local-area services and devices to connect and communicate with the wireless network. When a user of the mobile terminal or a local-area device requests a data service that can be delivered over either the wireless network or the local-area network, the more-efficient data path is determined and the user can select the preferred data path.
