METHOD, SYSTEM AND APPARATUS FOR IMPLEMENTING RINGBACK TONE SERVICE |
摘要 |
A method for implementing the ringback tone (RBT) service based on the next generation network (NGN) includes: an application server (AS) receives from a softswitch (SX) a call request initiated by a ring-to-me subscriber, which carries a ring-to-me access code; the AS obtains the ring-to-me tone ID from the RBT platform according to the ring-to-me access code and instructs a media resource server (MRS) to play the tone indicated by the ring-to-me tone ID to the calling party. Various embodiments disclose a system, an AS and an MRS for implementing RBT based on NGN. The present disclosure enables a calling party to listen to a ring-to-me tone while the called party is alerted and further, it enables the calling party to choose to listen to a ring-to-me tone or a ring-to-you tone according to the calling party's precedence setting.
