DETAILED DESCRIPTION
The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses.
The above two technical solutions for implementing the RBT reward in the prior art support CRBT users in which the donator and the rewarded party belong to the same CRBT platform. Moreover, in the solutions of the prior art, the donator can be charged via a CRBT platform, and the reward mode is limited to WEB, IVR and Short Message (SM).
Various embodiments of the disclosure provide a method for rewarding an RBT. The method for rewarding the RBT according to one embodiment of the disclosure will now be illustrated in conjunction with two modes.
FIG. 1a and FIG. 1b are schematic diagram and signaling flow chart of the first embodiment of the method for rewarding an RBT according to one embodiment of the disclosure respectively.
In the embodiment shown in FIG. 1a and FIG. 1b, a donator is a non-CRBT user, and a reward initiating party is a third-party platform which is a non-CRBT platform. In the mode, the third-party platform is required to be able to further implement a charging function for the RBT reward of the donator based on the processing for the RBT reward request. The specific process is as shown in FIG. 1b. 
In Step S101, the donator selects an RBT on a third-party platform in the mode of WEB, IVR or SM, designates a rewarded party and initiates an RBT reward.
The third-party platform is a non-CRBT platform the third-party platform may be any other platform which supports an RBT reward interface and further has a charging function, such as, SP web site, management system of the operator (such as System 97). The third-party platform has a service association with a CRBT platform. The RBT information can also be browsed on the third-party platform, and a data of CRBT user may also be configured on the third-party platform. The third-party platform usually is based on the CRBT platform, and an operation may be accomplished by invoking various interfaces provided by the CRBT platform.
In Step S102, the third-party platform sends an RBT reward request, which carries parameter information such as RBT donator, rewarded party and rewarded RBT code, to the CRBT platform via a predefined RBT reward interface.
The CRBT platform receives the RBT reward request from the third-party platform via an RBT reward interface and activates an RBT rewarding unit to perform the RBT reward operation.
The RBT reward operation process of the RBT rewarding unit mainly includes: determining whether the RBT exists according to the RBT code; determining whether the rewarded party is a CRBT user; and determining whether the customized RBT library of the rewarded party can receive a new RBT. If at least one of the above conditions is met, the RBT selected by the donator is downloaded to the customized RBT library of the rewarded party.
In the method mentioned above, the RBT reward operation is implemented. To further charge the donator and notify the rewarded party to configure a customized RBT, the CRBT platform may return reward result information (Successful or Failed) to the third-party platform.
In Step S103, the third-party platform receives the reward result information. In Step S104, the third-party platform determines whether the reward is successful. If the reward is successful, the third-party platform charges the donator for the rewarded RBT. Then, in Step S105, the third-party platform returns a charging result to the CRBT platform.
If the reward result information received by the third-party platform is Failed, in Step S104′, the third-party platform notifies the donator that the reward operation is failed, and illustrates a specific reason.
In Step S106, after the CRBT platform receives the charging result information from the third-party platform, the CRBT platform determines that the donator is charged successfully. If the donator is charged successfully, the CRBT platform notifies the rewarded party that the rewarded RBT is received and queries the rewarded party whether to configure the rewarded RBT as a default RBT.
If the donator is charged unsuccessfully, then in Step S106′, the CRBT platform deletes the RBT which is downloaded to the customized RBT library of the rewarded party in the Step S103; and in Step S107′, the CRBT platform returns information of reward failure caused by the charging failure to the third-party platform. Then, in Step S108′, the third-party platform notifies the donator that the RBT reward operation is failed.
In Step S107, after the rewarded party receives an RBT reward notification from the CRBT platform, the rewarded party determines whether to configure the rewarded RBT as a default RBT and returns a response message.
In Step S108, the CRBT platform receives the response message from the rewarded party. If the rewarded party determines to configure the RBT as the default RBT, the CRBT platform configures the RBT as the default RBT of the rewarded party.
In Step S109, the CRBT platform returns a reward success message to the third-party platform.
In Step S110, after the third-party platform receives the reward success message returned by the CRBT platform, the third-party platform notifies the donator that the RBT reward is successful.
FIG. 2a and FIG. 2b are schematic diagram and signaling flow chart of the second embodiment of the method for rewarding an RBT according to the disclosure respectively.
In the embodiment shown in FIG. 2a and FIG. 2b, the donator is a CRBT user, the reward initiating party is a CRBT platform (i.e., the first CRBT platform), and the rewarded party is a CRBT user which belongs to another CRBT platform (i.e., the second CRBT platform). In this mode, it is required that the donator is a CRBT user and the first CRBT platform can further implement a charging function on the RBT reward of the donator on the basis of the RBT reward operation processing function. The specific process is as shown in FIG. 23b. 
In Step S201, the donator selects an RBT on the first CRBT platform (for example, via WEB site, IVR or SM, etc., of the CRBT platform), designates the rewarded party and initiates an RBT reward.
In Step S202, the first CRBT platform sends an RBT reward request, which carries parameter information such as RBT donator, rewarded party, rewarded RBT code, to the second CRBT platform to which the rewarded party belongs via a predefined RBT reward interface.
After the second CRBT platform receives the RBT reward request via an RBT reward interface, the second CRBT platform activates an RBT rewarding module to perform the RBT reward operation.
The RBT reward operation process of the RBT rewarding module mainly includes: determining whether the RBT exist according to the RBT code, determining whether the rewarded party is a CRBT user, and determining whether the customized RBT library of the rewarded party can receive a new RBT. If at least one of the above conditions is met, the second CRBT platform downloads the RBT selected by the donator to the customized RBT library of the rewarded party.
In the method mentioned above, the RBT reward operation is implemented. To further charge the donator and notify the rewarded party to configure a customized RBT, the second CRBT platform may return reward result information (Successful or Failed) to the first CRBT platform.
In Step S203, the first CRBT platform receives the reward result information. In Step S204, the first CRBT platform determines that the reward is successful, the first CRBT platform charges the donator for the rewarded RBT.
If the reward is failed, in Step S204′, the first CRBT platform notifies the donator that the reward operation is failed, and illustrates the specific reason.
In Step S205, after the donator is charged, the first CRBT platform sends charging result information to the second CRBT platform via a predefined interface.
Moreover, in Step S205′, if the donator is charged unsuccessfully, the first CRBT platform notifies the donator that the reward operation is failed due to the charging failure.
In Step S206, after the second CRBT platform receives the charging result information, the second CRBT platform determines that the donator is charged successfully, the second CRBT platform notifies the rewarded party that the rewarded RBT is received and queries the rewarded party whether to configure the rewarded RBT as a default RBT.
If the donator is charged unsuccessfully, in Step S206′, the second CRBT platform deletes the RBT which is downloaded to the customized RBT library of the rewarded party in the Step S203.
In Step S207, after the rewarded party receives the RBT reward notification from the second CRBT platform, the rewarded party determines whether to configure the RBT as a default RBT and returns a response message.
In Step S208, the second CRBT platform receives the response message returned by the rewarded party. If the rewarded party determines to configure the RBT as the default RBT, the second CRBT platform configures the RBT as the default RBT of the rewarded party.
In Step S209, the second CRBT platform returns a reward success message to the first CRBT platform.
In Step S210, after the first CRBT platform receives the reward success message returned by the second CRBT platform, the first CRBT platform notifies the donator that the RBT reward is successful.
In both of the two RBT reward modes mentioned above, a reward request is processed first, an RBT is downloaded, and then the donator is charged, and if the donator is charged unsuccessfully, the rewarded RBT which has been downloaded will be deleted. However, embodiments of the disclosure are not limited hereto. According to the above content, those skilled in the art may understand that various embodiments of the disclosure may also employ a technical solution in which the donator is charged first, a reward request is processed and an RBT is downloaded, and if the download of the RBT is failed, the charged fee will be refunded.
In the method for rewarding an RBT according to one embodiment of the disclosure, the donator may select one or more RBTs from any platform which supports RBT reward interface and reward the RBTs to the rewarded party. Moreover, according to the support situation of the CRBT platform service, the donator may also select one or more RBT packages or RBT boxes and reward them to the rewarded party, and the corresponding rewarding and charging processes are similar to those of the FIG. 1b and FIG. 2b. After any platform which supports the RBT reward interface provides the RBT package or RBT box code selected by the donator to the CRBT platform in which the rewarded party exists, the CRBT platform of the rewarded party downloads the RBT package or RBT box corresponding to the RBT package or RBT box code to a customized RBT library of the rewarded party. If the donator is charged unsuccessfully, the RBT package or RBT box is deleted correspondingly.
In a method for rewarding an RBT according to various embodiments of the disclosure, the donator may designate one or more rewarded parties at the same time via the platform which supports the RBT reward interface, and the platform which supports the RBT reward interface initiates a reward request to the CRBT platform of each rewarded party one by one.
