The method of communication, it is characterised in that comprise the following steps：
Step 1：User's brush nfc card, communications applications read the associated person information of the nfc card and bound realizing；
Step 2：User's brush nfc card, communications applications read the card string number of the nfc card and whether inquire about the card string number in having bound
State, if unbound, carries out step 1, otherwise carries out step 3；
Step 3：Initiate video communication.
7. the method that a kind of NFC intelligent dialing systems based on set top box according to claim 6 realize video communication, its
It is characterised by, the detailed process of the step 1 is：
Step 1-1：Start communications applications, selection will bind contact person and activate binding button, associated person information comprising ID and/or
Messenger；
Step 1-2:Opening is swiped the card guiding interface program, preferential using NFC adapters lifting guiding interface NFC event handlings of swiping the card
After level, user card punching, Android operation system sends solicited message to guiding interface program, and the solicited message carries NFC marks
Label；
Step 1-3:Communications applications obtain NFC label from solicited message, and read from NFC label nfc card string number, then
Nfc card string number and associated person information write the SQlite databases of communication application program, set up binding relationship.
8. the method that a kind of NFC intelligent dialing systems based on set top box according to claim 7 realize video communication, its
It is characterised by, the detailed process of the step 3 is：
Step 3-1:When user card punching, set top box customizes Android operation system according to the solicited message received, starts and monitors
NFC events simultaneously obtain NFC label from solicited message, and nfc card string number is read from NFC label；
Step 3-2：:The nfc card string number obtained according to step 3-1, from the SQlite databases of communication application program local library
The associated person information of match query card binding, if not matching, points out user's card not bind account number also；If matching into
Work(, then carry out step 3-3；
Step 3-3：Television terminal or mobile phone terminal are distinguished according to the messenger of the nfc card, if mobile phone terminal, then certainly
It is dynamic to initiate video communication using communication cloud platform, it is if television terminal, then automatic to initiate video communication using SIP+WebRTC.
