摘要： Systems and methods for over-the-air (OTA) updating of data stored on Narrowband Internet of Things (NB-IoT) devices are provided. Such techniques enable updates to be provided on a timely basis for NB-IoT devices that lack short message service (SMS) capabilities, through polling an OTA update server in response to the occurrence of triggering events at the NB-IoT devices. Triggering events may be identified based upon conditions such as time since a previous update attempt or number of times the NB-IoT device has awoken since the previous update attempt. The updates may include updates to network lists used by the NB-IoT devices to determine preferred or forbidden networks, thereby reducing battery drain from repeated attempts to connect to inaccessible networks.

摘要： Methods, systems, and non-transitory computer readable media for enforcing a steering of roaming (SoR) decision. More particularly, enforcing the SoR decision includes receiving, at a proxy and from a user equipment (UE) located in a visitor network, a registration message to register with a home network, the registration message including an identifier of the visitor network. The proxy routes the registration message to a steering controller to determine a SoR policy decision. The proxy then enforces the SoR policy decision of the steering controller.

摘要： The current disclosure relates to a system and method for optimizing network access for a roaming device. In particular, the method includes receiving a request for network access from a client device. The method then determines if the device is roaming. If the device is roaming, the method then includes selecting one or more gateways for the roaming device and transmitting the selected gateways to the roaming device. Such gateways may be selected based upon device location within the roaming network to reduce latency or improve other performance metrics.

摘要： The present disclosure describes techniques that facilitate detecting a Voice over Long-Term Evolution (VoLTE) call request with a recipient call number that lacks a country code. The VoLTE call request may be initiated by a subscriber device while roaming in a VPLMN. Specifically, a Normalization and Alert Policy (NAP) system is described that is configured to analyze the VoLTE call request and determine an intended country code and adjust the recipient call number to include the country code. Further, the NAP system may analyze the adjusted recipient call number to determine whether initiating a VoLTE call in response to the VoLTE call request may trigger an alert condition. An alert condition may relate to determining that the VoLTE call request may initiate a cost-prohibitive VoLTE communication or that the VoLTE call request relates a fraudulent communication.

摘要： Methods, systems, and non-transitory computer readable media for intelligent steering of roaming of user equipment. More particularly, the methods include receiving, from a user equipment (UE) located in a visitor network, a registration message to register with a home network, the registration message including an identifier of the UE. The methods also include querying, by one or more processors, a steering controller using the identifier of the UE to obtain a roaming list customized for the UE. The methods also include pushing, by one or more processors, the roaming list to the UE.
