Abstract
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.
Claims17
A tunnel redirection method, comprising:
- receiving, by an Interworking Solution (IWS) function entity corresponding to an original tunnel, a tunnel redirection notification sent by an IWS corresponding to a new tunnel or a mobility management entity (MME);
- sending, by the IWS corresponding to the original tunnel, a signaling forwarding indication to the IWS corresponding to the new tunnel or the MME according to the notification;
- and
- receiving, by the IWS corresponding to the original tunnel, signaling forwarded by the IWS corresponding to the new tunnel or the MME according to the signaling forwarding indication.
An interworking function entity, comprising:
- a first receiving module, configured to receive a tunnel redirection notification sent by an Interworking Solution (IWS) function entity corresponding to a new tunnel or a mobility management entity (MME);
- a sending module, configured to send a signaling forwarding indication to the IWS corresponding to the new tunnel or the MME according to the notification received by the first receiving module;
- and
- a second receiving module, configured to receive signaling forwarded by the IWS corresponding to the new tunnel or the MME according to the signaling forwarding indication sent by the sending module.
A tunnel redirection method, comprising:
- receiving, by an Interworking Solution (IWS) function entity corresponding to an original tunnel, a tunnel redirection notification sent by an IWS corresponding to a new tunnel or a mobility management entity (MME);
- and
- terminating, by the IWS corresponding to the original tunnel, currently-performed signaling interaction according to the notification.
An interworking function entity, comprising:
- a receiving module, configured to receive a tunnel redirection notification sent by an Interworking Solution (IWS) function entity corresponding to a new tunnel or a mobility management entity (MME);
- and
- a processing module, configured to terminate currently-performed signaling interaction according to the notification received by the receiving module.
