Account registration method in DECT network cluster system

An account registration method in a Digital Enhanced Cordless Telecommunications (DECT) network cluster system, comprising:

• establishing communication with a DECT host through a DECT network cluster constructed in advance;
• receiving first account information allocated by the DECT host, wherein an account status of the first account information is registration snooping;
• initiating registration to a server according to the first account information, and obtaining a first registration result of a first account;
• sending the first registration result to the DECT host;
• if the first registration result is that the registration is successful, entering a first mode, wherein in the first mode, a DECT device directly initiates SIP signaling to the server;
• if the first registration result is that the registration is not responded to, obtaining a second registration result fed back by the DECT host, wherein the second registration result is the second registration result of the first account after the DECT host initiates registration to the server according to the first account information;
• and
• if the second registration result is that the registration is successful, entering a second mode, wherein in the second mode, the DECT device sends SIP signaling to the DECT host so that the DECT host forwards the SIP signaling.
