Abstract: User data may be transmitted through a signaling radio bearer (SRB) by using an NAS message. A new SRB different from the existing SRB0, SRB1, and SRB2 may be defined for transmission of the user data. The new SRB may be used to deliver the NAS message containing the user data before security is activated.
