Abstract
A method in an electronic device, comprises, in response to an Internet Protocol (IP) voice packetized data call being performed in a first call session of a first communication processor and occurrence of a handover event from the first communication processor to a second communication processor, receiving at least one of, (a) a control message and (b) IP packetized voice data, via the second communication processor. The control message received from the second communication processor is forwarded to the first communication processor.
Claims20
A method in an electronic device, comprising:
- processing a first Session Initiation Protocol (SIP) message and video data received from a first communication processor;
- in response to occurrence of a handover event from the first communication processor to a second communication processor, receiving voice data from the second communication processor;
- and
- forwarding a SIP message which is classified by an enhanced Packet Data Gateway (ePDG) client to the first communication processor through the ePDG client.
An electronic device comprising:
- a first communication processor;
- a second communication processor;
- an enhanced Packet Data Gateway (ePDG) client configured to classify a Session Initiation Protocol (SIP) message from the second communication processor;
- and
- an application processor configured to process a first Session Initiation Protocol (SIP) message and video data received from the first communication processor;
- in response to occurrence of a handover event from the first communication processor to the second communication processor, receives
- voice data from the second communication processor;
- and
- forwards the classified SIP message to the first communication processor.
An apparatus for supporting a multimedia service of an electronic device, comprising:
- a cellular communication processor, in a voice packet service based on Voice over Long Term Evolution (LTE) (VoLTE), configured to forward a first Session Initiation Protocol (SIP) message to an application processor and to process a second SIP message, the cellular communication processor supporting Internet Protocol (IP) Security (IPSec) protocol, the application processor being configured to process the first SIP message and video data from the cellular communication processor;
- and
- in response to a voice packet service based on the VoLTE transitioning to a voice packet service based on Voice over WiFi (VoWiFi), an enhanced Packet Data Gateway (ePDG) client classifies a SIP message and voice data from a WiFi communication processor and forwards the classified SIP message to the cellular communication processor, and forwards the voice data to the application processor.
