Abstract: A taper-adjustable roller includes a support shaft, support sheets arranged circumferentially around the support shaft, and a first push member. Circumferential surfaces of the support sheets at sides of the support sheets facing away from the support shaft are assembled to form a roll surface. Each support sheet has a first end and a second end in an axial direction of the support shaft. The support sheets are swingable relative to the support shaft. The first push member is disposed on the support shaft, and is configured to push the first ends of the support sheets in a substantially radial direction, to move the first ends towards the support shaft and move the second ends away from the support shaft, or to move the first ends away from the support shaft and move the second ends towards the support shaft.

Abstract: A method and system for implementing an interactive Ring Back Tone service are disclosed, and the method includes: obtaining (S101), when connecting a call, subscription information of an interactive Ring Back Tone service subscribed by a user; issuing (S102), when a called terminal is idle, to the called terminal a first subscription identifier for identifying an interactive Ring Back Tone service subscription of the user, where the first subscription identifier is for instructing the terminal to wait for playing of an interactive Ring Back Tone; and playing (S103), according to the interactive Ring Back Tone service subscribed by the user, the interactive Ring Back Tone to the called user.

Abstract: Embodiments of the present prevention disclose a service processing method, a communication system, and relevant devices to enable the user to more conveniently set ring tones and improve system security. The method includes: a management client located in a user terminal obtains a ring tone setting processing request of a user; and the management client sends the ring tone setting processing request to a service server through a mobile network so that the service server can perform corresponding processing according to the ring tone setting processing request. A communication system and the relevant devices are also disclosed in the embodiments of the present prevention. The embodiments of the present invention can enable the user to conveniently set the tone, reduce unnecessary network traffic, and improve system security.

Abstract: The present disclosure describes a method for rewarding an RBT, including selecting an RBT and initiating an RBT reward via a third-party platform in which a donator exists; processing an RBT reward request from a third-party platform, and downloading the RBT selected by the donator to a customized RBT library of the rewarded party when a predetermine condition is met. The CRBT platform may also return reward result information (Successful or Failed) to the third-party platform; the third-party platform receives the reward result information and charges the donator for the rewarded RBT. If the donator is charged successfully, the rewarded party is notified that the rewarded RBT is received; if the donator is charged unsuccessfully, the downloaded RBT is deleted from the customized RBT library of the rewarded party. The disclosure further describes a device and a system for implementing the method.

Abstract: Embodiments of this invention disclose a service processing method, a communication system and related device, for making it easier for a user to set up and manage ring personal group, and capable of enhancing system safety. The method comprises: acquiring, by a management client, a ring personal group processing request of a user; and transmitting, by the management client, the ring personal group processing request to a service server over a mobile network, so that the by service server performs the corresponding processing according to the ring personal group processing request. Embodiments of this invention further provide a communication system and related device. Embodiments of this invention make it convenient for the user to set up and manage ring personal group, and make it possible to reduce unnecessary network traffic and enhance system safety.
