Embodiment Construction

[0026] The current NGN service opening system does not have the function of service control ring back tone. According to the rich service characteristics of NGN, the upper layer application is required to control the ring back tone. For the service of personalized ring back tone, the application needs to actively play the color ringback tone to the calling party. Ring tone; and in order to maintain the experience of traditional public switched telephone network (PSTN) users, some services need to transparently transmit the ringback tone or prompt tone played by PSTN to the calling party.

[0027] The system structure of NGN open architecture is as follows: figure 1 shown, where:

[0028] The soft switch is used to complete functions such as service triggering, routing and call connection, and interacts with the service capability gateway through SIP signaling. After judging that the call triggers the service, the softswitch forwards the call to the service capability gateway ...

Abstract

The invention discloses a method for controlling ringback tone. The method comprises the following steps: a calling party initiates a call to a called party; the called party rings and sends a ringing signaling to a service capability gateway; For the processing method of the called ringing event, when determining the ringback tone playback mode indicated by the application server, report whether the ringing signaling carries the session description protocol SDP information to the application server; the application server sends the ringback tone to the service capability gateway to play mode, the service capability gateway controls the playback of the ringback tone according to the playback mode. The invention also discloses a communication system capable of controlling ringback playback.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and system for controlling ring back tone. Background technique [0002] The next-generation telecommunications network is a service-centric open network. Network capabilities are encapsulated and abstracted through application programming interfaces (APIs) based on open technologies, shielding the complexity of the telecommunications network itself, and providing a common and simple interface to the upper layer. The application controls network resources and provides rich services for the telecommunications network. Session Initiation Protocol (SIP protocol) is an important protocol in the next generation network, which is used to establish, change and terminate calls between users based on IP network. The service uses the network capability API, which is mapped to the underlying SIP protocol to control the call. [0003] In the NGN network based on the SIP prot...
