Abstract
Systems, devices, and techniques described herein relate to timer-initiated fallback. In an example method, a message associated with Quality of Service (QoS) sensitive services is received from a core network. In response to receiving the message, a timer is initiated. If the timer expires without having received a confirmation that a dedicated tunnel associated with the QoS-sensitive services has been established in the first core network, then a fallback process can be initiated.
