SECURE DISTRIBUTED HANDOVER SIGNALING
First Claim
1. A method comprising:
- sending a measurement report associated with a mobile communication device to a source base station, the measurement report including a first encryption parameter;
receiving a handover command including a second encryption parameter corresponding to a target base station from the source base station; and
sending a handover confirmation message to the target base station, the handover confirmation message including identification information corresponding to at least one of the source base station and the target base station.

Abstract
Provided are apparatuses and methods for providing security measures for a handover execution procedure in a communication network. In one example, the handover procedure is initiated by more than one base station. In another example, a base station may not launch a Denial or Service (DoS) attack towards other base stations or towards a core network using handover signaling messages. For example, a user device may send at least one encryption parameter, such as a Nonce associated with the user device to a source base station. Handover of the user device from the source base station to a target base station may be accomplished based on the at least one encryption parameter to avoid the DoS attack.

19. A computer readable medium storing computer readable instructions that, when executed by a processor, cause the processor to perform a method comprising:
-
receiving, at a source base station, a measurement report associated with a mobile communication device, the measurement report including an encryption parameter;
transmitting a context push message to a target base station, the context push message configured to initiate a handoff of the mobile communication device;
receiving a context confirmation message from the target base station;
transmitting a handover command to the mobile communication device; and
upon completion of the handover of the mobile communication device from the source base station to the target base station, receiving a handover completion message from the target base station. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28)
