Abstract
A method, an apparatus, and a system for processing session context are disclosed. The method for processing session context includes: receiving a reset notification message that carries a device identifier; confirming that a reset event corresponding to the reset notification message occurs on a peer device identified by the device identifier; and deleting an associated context related to the reset event. According to the present invention, after a local device receives a reset notification message from a peer device and before deleting an associated context related to the reset event of the peer device, the local device needs to confirm the authenticity of the reset notification message with the peer device. In this way, the associated context on the device will not be wrongly deleted due to the attack from a fake source address, and it is ensured that the associated context are correctly processed after a reset notification message is received, thus ensuring that the local device can perform normal communication and improving the system security.
