Claims20
An electronic device comprising:
- a first processor for managing security information for processing a security packet while performing a voice over internet protocol (VoIP) service, and configured to transmit, to a second processor, the security information comprising a security context for internet protocol security (IPsec) applied to the VoIP service, via an inter-process communication (IPC) message;
- and
- the second processor configured to decode the received security packet by using the security information transmitted from the first processor while the first processor is in an idle mode,
- wherein the security packet comprises a session initiation protocol (SIP) message for the VoIP service,
- wherein the first processor comprises an application processor (AP), and
- wherein the second processor comprises a communication processor (CP).
