摘要: Methods and systems for slow associated control channel signaling are disclosed. An example method for securing communications in a mobile network disclosed herein comprises transmitting a first variant of a message of a first type on a first slow associated control channel (SACCH) before ciphering is started on the first SACCH, and after ciphering is started on the first SACCH, transmitting a second variant of the message of the first type on the first SACCH, and subsequently transmitting the second variant of the message of the first type on the first SACCH, wherein the subsequently transmitted second variant of the message of the first type is the next transmitted message of the first type on the first SACCH.
