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.

摘要: A user equipment is provided comprising: 1) transceiver circuitry configured to operate in cells associated with at least one radio access technology (RAT) network; and 2) a controller configured to perform neighbour cell searches. The controller is further configured to determine when the user equipment enters a first RRC state from a second RRC state. In response to the determination, the controller determines a time period since a most recent search of neighbour cells was performed. The first RRC state is one of at least: CELL_PCH, URA_PCH and IDLE. The second RRC state is one of at least CELL_FACH and CELL_DCH.
