Embodiment Construction

[0082] Various exemplary embodiments consistent with the present invention provide techniques for providing security to inter-RAT CAs. By encrypting messages only once, processing power is saved compared to traditional techniques that attempt to implement a security solution for each RAT used. In addition, since excessive security operations are avoided, transmission delays are also reduced. Additionally, operators save the cost of creating a separate authentication infrastructure for each RAT.

[0083] Before describing various exemplary embodiments of the invention in further detail, reference is made to image 3 , image 3 Simplified block diagrams of various electronic devices and equipment suitable for use in practicing the example embodiments of the invention are illustrated.

Abstract

A method for security for inter-RAT carrier aggregation is disclosed. The method includes encrypting a message using an encryption technique for a first RAT. The method also includes sending, to a UE, at least a portion of the encrypted message using a different, second RAT. Sending using the second RAT does not further encrypt the at least a portion of the encrypted message. The method further includes receiving the at least a portion of the message encrypted using the first RAT protocol. Receiving uses the second, different RAT. The method also includes decrypting the at least a portion of the message using the first RAT protocol. Apparatus and computer readable media are also described.

Description

technical field [0001] The exemplary and non-limiting embodiments of the present invention generally relate to wireless communication systems, methods, apparatuses and computer programs, and more particularly to inter-radio access technology (inter-RAT) carrier aggregation. Background technique [0002] This section is intended to provide a background or context to the invention that is recited in the claims. The description herein may include enabling concepts, but not necessarily concepts that have been previously thought of or implemented. Therefore, unless otherwise indicated herein, what is described in this section is not prior art to the description and claims in this application and is not admitted to be prior art by inclusion in this section. [0003] The following abbreviations found in the specification and / or drawings are defined as follows: [0004] 3GPP Third Generation Partnership Project [0005] AP access point [0006] BW bandwidth [0007] CC componen...
