Abstract

The present invention provides a security method for handling a single wireless voice call continuity handover in a mobile device of a wireless communication system. The method includes having an ongoing circuit-switched service or having a radio resource control connection in a circuit-switched domain when the mobile device is served by a first network that supports the circuit-switched domain and a packet-switched domain; receiving a handover command from the first network to a second network that supports the packet-switched domain; from the multiplexer for the first network Generate a plurality of security keys for the second network end from a circuit switched key; and use the plurality of security keys for transmission and reception of the second network end.

Description

technical field [0001] The present invention relates to a method used in a wireless communication system and related communication devices, in particular to a method used in a mobile device of a wireless communication system to handle the security of a single wireless voice call continuity handover and related communication devices. Background technique [0002] The Long Term Evolution (hereinafter referred to as LTE) wireless communication system formulated by the 3rd Generation Partnership Project (3GPP) is currently considered to be able to provide high data transmission rate, low latency, and maximum packet A new wireless interface and wireless network architecture that optimizes and improves system capacity and coverage. In the LTE wireless communication system, the Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, hereinafter referred to as E-UTRAN) includes multiple evolved wireless base stations (evolved Node-B, ...
