Problems solved by technology

However, providing this solution addresses the problem of the eNB intra-case where both of the D2D pairings are under the same eNB or D2D area
Key generation (especially key pairing) in scenarios where D2D devices are under different eNBs or D2D areas has not been considered

Embodiment Construction

[0027] Methods, apparatus and computer programs for key pairing between peer D2D UEs in different eNBs or D2D areas are disclosed. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of embodiments of the invention. It is apparent, however, to one skilled in the art that the embodiments of the invention may be practiced without these specific details or with an equivalent arrangement. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring embodiments of the invention. Like reference numerals designate like elements throughout.

[0028] figure 1 is a wireless communication system in which at least one embodiment of the present invention may be practiced. In general, a wireless communication system includes a radio access network and a core network. The radio access network controls the cells and certain UEs oper...

Abstract

Methods and apparatus are provided for key pairing between peer D2D UEs in different eNBs or D2D areas. A method may comprise: receiving at a first access network node serving a first D2D area from a first user equipment in the first D2D area, a request for keys for a D2D communication between the first user equipment and a second user equipment, wherein the request comprises an identification of a second D2D area where the second user equipment is located and being different from the first D2D area; identifying a second access network node serving the second D2D area based on the identification; sending to the second access network node, a request for a security context of the second user equipment; and receiving from the second access network node the security context for obtaining the keys for the D2D communication.

Description

technical field [0001] The present invention generally relates to network-controlled device-to-device (hereinafter also referred to as "D2D") communication. More specifically, the present invention relates to an enhanced method and related apparatus for key pairing of D2D devices in different D2D areas. Background technique [0002] With the development of future services, next-generation wireless communication systems such as 3GPP (Third Generation Partnership Project) LTE (Long Term Evolution) and super systems, IMT-A (International Mobile Telecommunications-Advanced) systems, etc. High speed, large capacity and high QoS (Quality of Service) for one billion subscribers. In this regard, efforts have been made to achieve network-controlled D2D communication to reduce the load on cellular communication networks. Examples of said D2D communication include direct communication among clusters of neighboring devices and autonomous D2D communication in a cellular network. In sa...
