  • CRBT Coloring Ring Back Tone
  • Customers can customize the ring back tone of their own phone according to their own preferences and requirements.
  • the ringback tone can be either music, advertising, or voice recorded by the customer.
  • the implementation of the CRBT system is roughly divided into three types: Service-node mode, Intelligent (IN) mode, and Switch mode.
  • the three methods have their own advantages and disadvantages.
  • the switch mode is the most reasonable CRBT implementation solution, and it requires fewer relay resources: First, the CRBT center does not need to call the called party, but the switch itself completes Second, when the called party answers to start the call, the switch to the ring back tone center circuit will be released. Moreover, from the whole call, the ring back tone center is only a pure playback device, and the security requirements are not high, and its reliability does not affect the normal call. So the switch mode is currently the most popular way.
  • the called end office initiates a call to the ring back tone center, requesting to play the CRBT;
  • the calling end office removes the voice channel between the center and the ring back tone center, and the ring back tone center ends playing the ring back tone.
  • the called end office and the ring back tone center usually pass the telephone user part.

  • the called end office If the called end office is directly connected to the CRBT center, after the switch receives the release message from the CRBT center, the called end office actively triggers the call to the CRBT center, knowing that the release message is from the CRBT center, so the failure tone will not be played.

  • a device such as a call end office or a gateway office needs to trigger a CRBT service
  • the device initiates a CRBT call
  • the CRBT call is transferred to the CRBT center through the gateway.
  • the specific method for the device to initiate a CRBT call is as follows: Use the reserved field in the CRBT service trigger message, or add a new field to indicate that the call triggered by the message is a CRBT call, and send the message to the gateway that acts as the transfer CRBT call.
  • the gateway After receiving the message from the device, the gateway records that the call triggered by the message is a CRBT call, that is, records the current call as a CRBT call, and then forwards the message to the CRBT center.
  • the gateway When the gateway receives the release message from the CRBT center, or if the ringback fails due to its own reasons, the gateway will know that the current call is a CRBT call after the gateway records the inquiry, and the gateway does not play the failure tone to the user.
  • the method of the present invention mainly comprises two parts: processing of a CRBT call by a device that triggers a CRBT, and processing of a call failure by a gateway that transfers a CRBT call.
  • processing of a CRBT call by a device that triggers a CRBT and processing of a call failure by a gateway that transfers a CRBT call.
  • the following is an example of triggering a color ring call by the calling end office, and further details the two parts of the solution:
  • the corresponding connection message is an IAM message, because the call parameter Forward call in the message.
  • the reserved fields of the indicators are bitM, bitN, bitO, and bitP. Here, you can fill in the bitP of 1 to indicate the CRBT call. If you do not want to use the reserved field, you can add a field to the IAM message to indicate the CRBT call.
  • the gateway determines whether the recorded call in the data area is transferred to the CRBT center. If yes, it does not place the call to the call center. Sound, that is, the call failure tone will not be misplaced to the user; if not, it will be processed according to the normal call flow, and the detailed flow is shown in FIG. 4.
  • FIG. 5 is a schematic structural diagram of an implementation system for avoiding the failure of the gateway to resume the ring tones of the color ringing according to the present invention.
  • the system for implementing the method for avoiding the failure of the color ringing of the color ringing of the gateway is as follows: the CRBT service triggering device and the gateway; ,
  • the CRBT service triggering device may be a call end office or a gateway office.
  • the gateway is configured to receive the message sent by the CRBT service triggering device, and record the call triggered by the message as a CRBT call, that is, record the current call as a CRBT call, and forward the message to the CRBT center;
  • the inquiry call is made to know that the current call is a CRBT call, and no failure tone is played to the user.
  • the present invention identifies a CRBT call by using a reserved field of a trigger message sent to the CRBT center, or a newly added field, thereby ensuring that when the gateway fails to ring the ring tones, the user is not mistakenly played, effectively improving
  • the reliability of the CRBT service is beneficial to the promotion of the CRBT service.

Abstract

La présente invention concerne un procédé d'implémentation permettant d'éviter la transmission d'une erreur d'une tonalité de retour d'appel personnalisée due à une défaillance de connexion d'un commutateur tête de ligne. Ledit procédé consiste à : placer une marque dans un message déclenchant un service de tonalité de retour d'appel personnalisée afin d'indiquer qu'un appel, déclenché par le message déclenchant un service de tonalité de retour d'appel personnalisée, est un appel de tonalité de retour d'appel personnalisée, et envoyer le message déclenchant un service de tonalité de retour d'appel personnalisée à un commutateur tête de ligne qui fonctionne pour expédier l'appel de tonalité de retour d'appel personnalisé; après la réception du message, le commutateur tête de ligne enregistre que l'appel courant est un appel de tonalité de retour d'appel personnalisé, et expédie le message déclenchant un service de tonalité de retour d'appel personnalisée à un centre de tonalité de retour d'appel personnalisée; et lorsque le commutateur tête de ligne ne parvient pas à connecter la tonalité de retour d'appel personnalisée, après l'obtention que l'appel courant est un appel de tonalité de retour d'appel personnalisée en interrogeant l'enregistrement, ne pas transmettre une tonalité d'erreur à un utilisateur. Le procédé de la présente invention améliore efficacement la fiabilité du service de tonalité de retour d'appel personnalisée et n'affecte pas l'expérience d'un utilisateur appelant. Par conséquent, la présente invention concerne également un système d'implémentation permettant d'éviter la transmission d'une erreur d'une tonalité de retour d'appel personnalisée due à une défaillance de connexion d'un commutateur tête de ligne, comprenant un dispositif déclenchant un service de tonalité de retour d'appel personnalisée et un commutateur tête de ligne.
