PROBLEM TO BE SOLVED: To provide a method and apparatus for configuring SRB in a wireless communications system. SOLUTION: The method includes: performing a first ciphering procedure for a first NAS message to get a second Non-Access Stratum message; performing the first ciphering procedure for a third NAS message to get a fourth NAS message; generating a RRC message, which is not ciphered, in a RRC layer; combining the second NAS message with the RRC message to form a first concatenated message; performing a second ciphering procedure for the first concatenated message to get a second concatenated message; and not combining the fourth NAS message with any RRC message to get a non-concatenated message. The method is characterized in that the second ciphering procedure is not performed for the non-concatenated message, the non-concatenated message is transmitted on a first SRB, and the second concatenated message is transmitted on a second SRB being different from the first SRB.
