Step 1301 is optional steps.When there is step 1301, be to initiate the capability query to user terminal by network side; While only there is step 1302 when not there is not step 1301, be initiatively to network side reporting ability information by user terminal.

In addition, optional, after step 1302, also there is step 1303.

1303, user terminal receives the minimizing transmission control layer confirmation message initiation message that network side sends.

User terminal receives after this minimizing transmission control layer confirmation message initiation message, opens the function that reduces transmission control layer confirmation message.
