METHOD AND APPARATUS FOR HANDLING PACKET LOSS IN MOBILE COMMUNICATION NETWORK

摘要

A method and an apparatus for handling packet loss in a mobile communication network are provided. In the method for handling a call when packet loss occurs, the apparatus receives an uplink packet from a user equipment (UE) and deciphers the packet based on a first hyper frame number (HFN). When the deciphering based on the first HFN fails, the apparatus changes an HFN value from the first HFN to a second HFN and then further deciphers the packet based on the second HFN.

1. A method for handling a call in case of packet loss in a mobile communication network, the method comprising:
receiving an uplink packet from a user equipment (UE); deciphering the packet based on a first hyper frame number (HFN); changing an HFN value from the first HFN to a second HFN when a failure of the deciphering based on the first HFN occurs; and further deciphering the packet based on the second HFN.
