Then, read the key assignments in the terminal system registration table of contact object place, obtain the contact person and belong to the program information of installing in the terminal, and obtain the corresponding support data format relevant information of program according to the program information of installing in the terminal;
At last, compare, upgrade and to support the data format list with the support data format list of storage before.
For example, be 72h the blanking time that the user sets, and then sets up the support data format list to a certain contact object first from user A, every at a distance from 72 hours, and this support data format list is once upgraded.
In step S102, the format information of the target data that collection user A is sent is with supporting the data format list to compare.
When data are sent; The transmit leg client at user A place obtains the IP address and the port port of the other side's login through the dynamic message of recipient's client at inquiring user B place; Generate and send socket; Utilize and to send socket,, obtain the format information of the target data of sending through the message type field in the packet that reads user A transmission target data to recipient's client transmission packet.
The target data format information that obtains is compared with the support data format list to user B.Determine whether that according to judged result needs carry out format conversion to target data.
In step S103, judge whether target data is carried out format conversion.
If through the comparison of a last step, comprise the form of target data in the support data format list to user B, i.e. target data is read in the instant communication client counterpart terminal support of user B, then changes step S106;
If through the comparison of a last step, do not comprise the form of target data in the support data format list to user B, promptly the instant communication client counterpart terminal of user B does not support to read target data, then changes step S104.
In step S104, target data is carried out format conversion.
When judging that recipient's instant communication client counterpart terminal is not supported to read target data, promptly need carry out format conversion to target data.
Particularly, the target data format conversion includes following two kinds of conversion regimes one of which at least,
Mode one is gathered the target data format information, reads the support data format content that obtains user B to the support data format list of user B, confirms the target data format transformation;

Further, in the aforesaid way one, that confirms the target data format transformation comprises following two kinds of patterns one of which at least,
Pattern one, different classes of to the target data form, the format transformation of preset acquiescence respectively;
Pattern two, different classes of to the target data form gathered user B to the highest data format of this classification data applying frequency, the object format with this data format during as the target data format conversion.
To pattern one, the classification of described target data form comprises audio class data format, video class data format, images category data format and text class data format one of which at least.
For example; The default form that user A preestablishes the audio class data is mp3; When user A when user B sends form and is the audio file of AAC; Through the support data format list of contrast, find that user B does not support the audio file of this form, need carry out format conversion to this target data to user B.Because target data is the audio class data, be the data format that the audio file of AAC converts mp3 into therefore with this form, be used further to transfer of data.
Generally, every type of selected default form of data format is the modal form of this class data file, perhaps reads the data format that the program of the type is generally supported.Certainly, user A also can confirm that user B supports under the situation of data format, sets default form according to the operating position of user B.
To pattern two, said collection user B specifically comprises the steps: to the applying frequency of this classification data different-format
Step a, the time range of setting applying frequency data acquisition;
Step b gathers the reading times information that is directed against different-format in these classification data in the user B counterpart terminal;
Step c according to the temporal information and the reading times information that collect in above-mentioned two steps, calculates the applying frequency of user B to different-format in these classification data.
With the audio class data instance, user B is in a period of time, and the voice data number of times that reads the mp3 form is 328 times, and the voice data number of times that reads the ogg form is 48 times.User B reads the data height of the frequency of mp3 formatted data than the ogg form in this short time so, and therefore can be regarded as user B is mp3 to audio class data file data format comparatively commonly used.When user A to user B send user B terminal when not supporting the voice data of form, be used further to transfer of data after then converting the voice data of this form into the mp3 form.
In step S105, through a last step, after the format conversion of target data finished, target data promptly was sent to the instant communication client at user B place through the instantaneous communication system server.
