Tunnel redirection method and interworking function entity

摘要

A tunnel redirection method and an interworking function entity are disclosed. An IWS corresponding to an original tunnel receives a tunnel redirection notification sent by an IWS corresponding to a new tunnel or an MME. A currently-performed signaling interaction is terminated according to the notification. The IWS corresponding to the new tunnel or the MME sends a tunnel redirection notification to the IWS corresponding to the original tunnel. The IWS corresponding to the original tunnel terminates the currently-performed signaling interaction.

1. A tunnel redirection method, comprising:
receiving, by an Interworking Solution (IWS) corresponding to an original tunnel, a tunnel redirection notification sent by an IWS corresponding to a new tunnel, the tunnel redirection notification indicating that a user equipment (UE) is being redirected from the original tunnel to the new tunnel; sending, by the IWS corresponding to the original tunnel, a signaling forwarding indication to the IWS corresponding to the new tunnel according to the notification; and receiving, by the IWS corresponding to the original tunnel, signaling forwarded by the IWS corresponding to the new tunnel according to the signaling forwarding indication, wherein receiving the tunnel redirection notification comprises receiving the tunnel redirection notification that is sent, according to an identifier of the IWS corresponding to the original tunnel, by the IWS corresponding to the new tunnel, wherein the identifier of the IWS corresponding to the original tunnel is sent by a mobility management entity (MME) to the IWS corresponding to the new tunnel after the MME determines that a tunnel needs to be redirected.
