Abstract
A method for directly communicating handsets is provided. The method includes the following steps of providing a calling handset and a called handset, inputting a first number to the calling handset for obtaining a first identification (ID) code therefor, inputting a second number to the called handset for obtaining a second ID code therefor, transmitting the first ID code from the calling handset to the called handset when the calling handset is to call the called handset, receiving the first ID code by the called handset, identifying whether the first ID code matches with the second ID code, and synchronizing the two handsets for a direct communication.
Claims24
A method for directly communicating handsets, comprising the following steps of:
- providing a calling handset and a called handset;
- inputting a first number to said calling handset for obtaining a first identification (ID) code therefor;
- inputting a second number to said called handset for obtaining a second ID code therefor, wherein each of said first and second ID codes comprises a direct communication ID code and a channel number;
- transmitting said first ID code from said calling handset to said called handset when said calling handset is to call said called handset;
- identifying whether said first ID code matches with said second ID code;
- and
- synchronizing said two handsets for a direct communication if said first ID code matches with said second ID code,
- wherein when a handshake fails between said two handsets, a starting communication signal is sent from said called handset to said calling handset and a phonetic signal of said called handset is connected.
A method for directly communicating handsets comprising the steps of:
- providing a first handset and a second handset;
- causing said first handset to enter into a direct communication idle mode;
- causing said first handset to enter into a direct communication calling mode once said first handset is desired to require a direct communication;
- receiving a calling signal from said second handset;
- causing said first handset to enter into a direct communication receiving mode upon identifying said calling signal contains a partial signal matching with a corresponding one of said first handset for synchronizing said first and second handsets;
- causing said first handset to enter into a direct communication connection mode;
- and
- causing said first handset to enter into a directly communicating mode upon transmitting a data,
- wherein said directly communicating mode proceeds the step of returning to said direct communication idle mode upon receiving a stop communication signal from said second handset;
- returning to said direct communication idle mode if a handshake between said handsets fails;
- and
- transmitting a stop communication signal to enter into said direct communication mode when said first handset has an interrupted communication.
