ENHANCED SINGLE VOICE RADIO CALL CONTINUITY USING PACKET DATA NETWORK BI-CASTING
摘要
A method can comprise providing single voice radio call continuity using packet data network bi-casting, wherein the call continuity is provided during a handover of a user equipment from a real- time transport protocol voice to a circuit switched voice call In such a method, the real-time transport protocol voice can be carried m a long term evolution system and the circuit switched voice call can be carried in a second or third generation system The method can be performed by a serving network of the user equipment.
