<p>The present invention discloses a method and system for media modification, which is used for solving the problem in the related art that it is not considered during media modification whether the user confirmation or precondition of media modification is required, thereby resulting in technical defects, such as possible bearing resource embezzlement, producing redundancy, etc. The present invention regards the 2000K message of Re-INVTTE as the confirmed time point of the media addition and/or modification; in the case that there is a precondition and the user confirmation is not required, the time point when the precondition is satisfied is regarded as the confirmed time point of the media component addition and/or existing media component modification; in the case that there is a precondition and the user confirmation is required, the 200OK response message of the Re-INVTTE message is regarded as the confirmed time point of the media component addition and/or existing media component modification. By the present invention, a premature confirmation of the modification can be avoided before the resource is available or before the user confirmation, and thereby the bearing resource embezzlement and producing unnecessary redundant steps are prevented.</p> |
