Abstract

A method of enabling key handling for a handover between different domains may include determining whether an indication of a potential key mismatch is present responsive to an attempt to conduct a handover between a first domain and a second domain, and defining validity of a most recent key set used for ciphering communication between a mobile terminal and a network device based on a result of the determining.

Description

technical field [0001] Embodiments of the invention generally relate to communications in a multi-radio access technology (RAT) environment and / or in a single-RAT environment, and more particularly to a method for inter-domain mobility (e.g., single-radio voice call continuity) - SR-VVC) Apparatus and method for implementing key handling. Background technique [0002] Today's communications era has brought about a dramatic expansion of wired and wireless networks. Computer networks, television networks, and telephone networks are experiencing an unprecedented technological expansion driven by consumer demand. Wireless and mobile networking technologies have addressed related consumer demands while providing more flexibility and immediacy of information transfer. [0003] Current and future networking technologies continue to facilitate the simplicity and convenience with which users communicate information. Such increased simplicity and convenience for users to communicat...
