Embodiment Construction

[0026] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0027] When an existing terminal calls multiple terminals at the same time, the server usually manages the multiple called terminals. However, once the server breaks down, it will lead to the inability to manage multiple called terminals, so that the entire calling system cannot work normally. At the same time, the data is transmitted through the ser...

Abstract

The present application discloses a multi-terminal calling method and device, which are used to solve the problems that the device cannot operate due to a server failure and the call efficiency is low when a first terminal initiates a call to multiple second terminals at the same time. The method includes: based on the P2P communication protocol of the hole punching mechanism, the first terminal sends call request signaling to several second terminals according to the identification handles stored in the signaling server by the second terminals, and the first terminal receives the call request signaling in the idle state. For the ringing signaling and the requesting answering signaling sent by the second terminal, the first terminal checks the state identifications of other several second terminals; The second terminal that sends the answering request signaling sends a confirmation signaling to establish a call connection. Through the above method, the present application reduces the occurrence rate of faults during the call process and improves call efficiency.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a multi-terminal call method and device. Background technique [0002] In recent years, with the rapid development of the communication industry. The technology that a calling terminal can call multiple called terminals at the same time is gradually being widely used, especially in hospitals where patients simultaneously initiate calls to nurse station hosts, duty room extensions, door extensions, doctor’s office extensions, medical hand-held mobile terminals, etc. The calling intercom system provides convenience for medical management. [0003] The existing method for a calling terminal to simultaneously call multiple called terminals also requires the intervention of an intermediate server to manage several called terminals. This communication connection method reduces the signal transmission rate to a certain extent. And once the server breaks down, the...
