Update Overhead Information Substate

2.6.3.2 Update Overhead Information Substate

Upon entering the Update Overhead Information Substate, the mobile station shall set the System Access State timer to a value of T_41m seconds. The mobile station shall set PAGED to NO.

If the System Access State timer expires while in this substate, the mobile station shall enter the System Determination Substate of the Mobile Station Initialization State with a system lost indication (see 2.6.1.1).

If the mobile station declares a loss of the Paging Channel or the Primary Broadcast Control Channel (see 2.6.3.1.8), the mobile station shall perform the following:

• If PACA_s is equal to enabled, the mobile station shall set PACA_s to disabled and PACA_CANCEL to ‘0’, shall disable the PACA state timer, and should indicate to the user that the PACA call has been canceled.

• The mobile station shall declare an access attempt failure and update its registration variables as specified in 2.6.5.5.3.2.

• The mobile station shall enter the Mobile Station Idle State.

If PACA_s is equal to enabled, the mobile station shall set PACA_CANCEL to ‘1’ when the user directs the mobile station to cancel a PACA call.

• If this substate was entered with an order/message response indication and the mobile station has not performed an access entry handoff, the mobile station shall determine whether the message resulting in the response was received on the current Paging Channel or Forward Common Control Channel. If the message was received on the current Paging Channel or Forward Common Control Channel, the mobile station shall enter the Mobile Station Order/Message Response Substate; otherwise, the mobile station shall discard the response and enter the Mobile Station Idle State.
