More Information
Summary:A device establishes a first encrypted tunnel with a first active security gateway at a first data center to enable the device to communicate, via the first encrypted tunnel, with a first access and mobility management function (AMF) at the first data center. The device forwards, via the first encrypted tunnel and the first active security gateway, a first User Equipment device (UE) message to the first AMF. The device determines an occurrence of a failure or overload condition at the first active security gateway, and establishes, based on the determined occurrence of the failure or overload condition, a second encrypted tunnel with a standby security gateway at a second data center to enable the device to communicate, via the second encrypted tunnel, with the first AMF. The device forwards, via the second encrypted tunnel and the standby security gateway, at least one second UE message to the first AMF.
