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.

Managing mobile device voice over Wi-Fi handover

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&#xd7; network mobile communication technology, or a LTE network mobile communication technology.

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 WLANs.

Arrangement for controlling access to data network

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.

System and method for provision of IMS based services for legacy CS UE with home node B access

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. Authentication of the mobile device may be bypassed and the mobile device is instructed to transmit its actual electronic serial number for future registrations. Once the activation process is completed, the temporary activation identifiers are overwritten.
