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 and wherein the measurement report is configured to cause the source base station to send a context push message to a target base station, wherein the context push message includes one or more encryption keys and a once associated with a network;
receiving, by the mobile communication device, a handover command including a second encryption parameter corresponding to the target base station from the source base station, wherein the mobile communication device is different from the target base station and 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.

13. An apparatus comprising:
-
at least one processor; and at least one memory operatively coupled to the at least one processor and storing computer readable instructions that, when executed, cause the apparatus to; send a measurement report to a source base station, the measurement report including a first encryption parameter and wherein the measurement report is configured to cause the source base station to send a context push message to a target base station, wherein the context push message includes one or more encryption keys and a Nonce associated with a mobile communication device; receive a handover command including a second encryption parameter corresponding to the target base station from the source base station, the target base station and the source base station being different from the apparatus; and send 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 or the target base station. - View Dependent Claims (14, 15, 16)
