Abstract: This application provides a method for issuing a digital certificate performed by a digital certificate issuing center that includes a public-private key generation module and an authentication module. The method includes: receiving a public-private key request from a node in a blockchain network; generating a public key and a private key of the node by using the public-private key generation module, and transmitting the public and private keys to the node; receiving the public key of the node and registration information of the node, and authenticating the registration information by using the authentication module; and generating, in accordance with a determination that the authentication succeeds, a digital certificate of the node by using the authentication module, and transmitting the digital certificate to the node. The embodiments of this application can improve the probative value of an issued digital certificate, thereby improving the security of data exchange in a blockchain network.

Abstract: A method and terminal device for transferring a telephone call, are provided. The method comprises: detecting if an incoming call is received; displaying an incoming call interactive interface containing an incoming call transferring option, if the incoming call is detected; transferring the incoming call to a terminal device corresponding to a designated number when the incoming call transferring option is chosen. As the user is allowable to choose whether the incoming call should be transferred according to actual needs, the problem of automatically transferring incoming calls under some circumstances not suitable for transferring a telephone call may be avoided, thereby achieving more intelligent call transfer manner with more flexibility and better effect for transferring a telephone call.
