Updates to support network based internet protocol flow mobility
Various embodiments may be generally directed to techniques for UE initiated and network initiated IP flow mobility. Various embodiments provide techniques for sharing IP flow routing rules and/or filters between a UE and various network infrastructure components using existing network based protocols or extensions thereto. Various embodiments provide techniques for provisioning network based IP flow mobility triggers and for ensuring UE connections to a 3GPP network are maintained in the absence of any 3GPP network IP flows.
