Claim of US Patent No. 10,117,206

1. A method for synchronizing content, comprising:determining, by a first terminal, first terminal sharing content;
sending, by the first terminal, a synchronization group create message to a second terminal, the first terminal and the second terminal being in a same user group created on an instant messaging application, the synchronization group create message carrying a first terminal identifier and a synchronization group identifier, the synchronization group create message being used for requesting that the second terminal join a synchronization group, and the first terminal sending the synchronization group create message to the second terminal comprising multicasting, by the first terminal, the synchronization group create message to the second terminal in a local area network;
receiving, by the first terminal, a synchronization group join message from the second terminal, the synchronization group join message indicating that the second terminal has agreed to join the synchronization group, the synchronization group join message comprising a second terminal identifier and the synchronization group identifier, the synchronization group being a group in which the first terminal is allowed to automatically synchronize with the second terminal, and the first terminal receiving the synchronization group join message from the second terminal comprising receiving, by the first terminal, the synchronization group join message multicasted in the local area network from the second terminal;
storing, by the first terminal, the second terminal identifier in a group member information;
subsequently discovering, by the first terminal, the second terminal according to the group member information;
establishing, by the first terminal when the first terminal determines that the second terminal belongs to the same synchronization group as the first terminal, a connection to the second terminal according to the second terminal identifier and using a short-range wireless communications technology; and
synchronizing, by the first terminal, the first terminal sharing content and second terminal sharing content.
