Abstract
Apparatuses, methods, and systems are disclosed for network function reallocation with security context. One apparatus includes a processor and a transceiver. The processor is configured to detect, at a first network function of a mobile wireless communication network, that the first network function cannot serve a requested network slice from a user equipment ('UE') device. The transceiver is configured to send, from the first network function via a second network function, a reroute message to a third network function of the mobile wireless communication network. The reroute message includes an initial non-access stratum (“NAS”) message retrieved during NAS security mode command (“SMC”) procedure with the UE device and a security configuration. The third network function uses the initial NAS message and the security configuration to determine a security context for the UE device and serve the requested network slice from the UE device.
