Communication methods, communication device and communication systems

Abstract

The present disclosure relates to the technical field of communications. Provided are communication methods, a communication device and communication systems. A communication method comprises: a calling terminal sending a first INVITE message to a network device, wherein the first INVITE message comprises feature information of a called terminal, and the network device is configured to receive the first INVITE message sent by the calling terminal; and on the basis of the feature information, querying telephone number information of the called terminal, and on the basis of the telephone number information, establishing a call between the calling terminal and the called terminal. In the present disclosure, when a calling terminal has not obtained the telephone number of a called terminal, a call is initiated on the basis of feature information of the called terminal, and information interaction can be performed subsequently by means of a sensing function of a network to query telephone number information of the called terminal, and the queried telephone number information of the called terminal is used to replace the feature information thereof for calling, thereby realizing a voice call between the calling terminal and the called terminal.
