According to some embodiments, a method in a network node of a wireless communication network comprises determining that a plurality of S1-AP UE contexts maintained by the network node remain valid after a SCTP failure; generating an S1 Setup Request message comprising an indication that the UE contexts remain valid; and communicating the S1 Setup Request message to a MME. In particular embodiments, a method in an MME comprises receiving an S1 Setup Request message from a network node comprising an indication that UE contexts maintained by the network node remain valid after a SCTP failure. The MME determines a plurality of UE contexts maintained by the MME remain valid after a SCTP failure; generates an S1 Setup Response message comprising an indication that UE contexts maintained by the MME remain valid; and communicates the S1 Setup Response message to the network node.
