Abstract: The present disclosure is directed at systems, methods and media for providing bearer call-back services for bearers that have been rejected or pre-empted by a network apparatus in a core network. In some embodiments, if a network apparatus enters a state in which it becomes necessary to reject or pre-empt a bearer associated with a user equipment (UE) (e.g., due to load conditions in a radio access network, the core network, or an application server), the network apparatus can send to the UE a call-back message when the network apparatus exits the state that precipitated the bearer rejection or pre-emption. By sending a call-back message, the network apparatus can save the UE from multiple unsuccessful attempts to establish a bearer, or from waiting an unnecessarily long time before establishing a bearer.
