Title:
無線通信アクセス技術(RAT)間のハンドオーバーにおける単一無線の音声呼継続性(SRVCC)を処理するための方法及び装置
Document Type and Number:
Japanese Patent JP5272028
Kind Code:
B2
Abstract:
The techniques introduced herein provide a system and method for determining whether an inter-RAT handover is an SRVCC handover, and for performing the subsequent SRVCC handover. The techniques include receiving a handover command message that does not include SRVCC related information elements, for example "RAB info to replace," but continuing with an SRVCC handover using a circuit-switched RAB provided in the information for setup. The techniques also include receiving a handover command message that does include SRVCC related information elements and performing the SRVCC handover by an alternative method.
