A method for implementing network side and terminal side service adaptation

The invention disclosed a method to realize the traffic adaptation between network side and terminal side. The invention includes: A. the network side sends message of the requesting of terminal ability information to user, before sending traffic to user terminal; B. after receiving the message, user terminal sends response message which supplies the user terminal ability information to the network side; C. according to the user terminal ability information, the network side sends the adaptation traffic notification corresponded to its ability to the user terminal. The method can make the network side get the ability information of the receiving end timely and accurately. Consequently, the user terminal could analyze the information accurately. Moreover, the users' perception of using the MMS traffic would be sharply increased, and a more flexible traffic-offering mode is supplied for operator.
