2.6.3.2 Update Overhead Information Substate


In this substate, the mobile station monitors the Paging Channel until it has received the current configuration messages. The mobile station compares sequence numbers to determine whether all of the configuration messages are up-to-date. To make sure it has the latest access parameters, the mobile station receives at least one message containing the ACC_MSG_SEQ field (except in case of a page response, since the initiating General Page Message contains ACC_MSG_SEQ), and waits, if necessary, for an Access Parameters Message.

Upon entering the Update Overhead Information Substate, the mobile station shall set the System Access State timer to a value of T41m 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).

While in the Update Overhead Information Substate, the mobile station shall monitor the Paging Channel. If the mobile station declares a loss of the Paging Channel (see 2.6.2.1.1.4), the mobile station shall perform the following:

• If PACAs is equal to enabled, the mobile station shall set PACAs to disabled and PACA_CANCEL to ‘1’, 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 PACAs 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 the mobile station receives any of the following messages, it shall process the message as follows:

  1. System Parameters Message: The mobile station shall process the parameters from the message (see 2.6.2.2.1).

  2. Access Parameters Message: The mobile station shall process the parameters from the message (see 2.6.2.2.2).

  3. Neighbor List Message: The mobile station shall process the parameters from the message (see 2.6.2.2.3).

  4. CDMA Channel List Message: The mobile station shall process the parameters from the message (see 2.6.2.2.4).

  5. Extended System Parameters Message: The mobile station shall process the parameters from the message (see 2.6.2.2.5).

  6. Global Service Redirection Message: The mobile station shall process the parameters from the message (see 2.6.2.2.6).

  7. Extended Neighbor List Message: The mobile station shall process the parameters from the message (see 2.6.2.2.7).

  8. General Neighbor List Message: The mobile station shall process the parameters from the message (see 2.6.2.2.8).

  9. Lock Until Power-Cycled Order: The mobile station shall record the reason for the Lock Until Power-Cycled Order in the mobile station’s semi-permanent memory (LCKRSN_Ps-p equals the least-significant four bits of ORDQr). The mobile station should notify the user of the locked condition. The mobile station shall then enter the System Determination Substate of the Mobile Station Initialization State with a lock indication (see 2.6.1.1), and shall not enter the System Access State again until after the next mobile station power-up or until it has received an Unlock Order. This requirement shall take precedence over any other mobile station requirement specifying entry to the System Access State.

  10. General Page Message: If CURR_ACC_MSG_SEQ is equal to NULL, the mobile station shall set CURR_ACC_MSG_SEQ to ACC_MSG_SEQr. The mobile station shall compare CONFIG_MSG_SEQs to CONFIG_MSG_SEQr. If the comparison results in a mismatch, the mobile station shall set CONFIG_MSG_SEQs to CONFIG_MSG_SEQr. The mobile station may ignore the rest of the message. If this substate was not entered with an origination or page response indication, the mobile station may also determine whether there is a page match. If the mobile station attempts to determine whether there is a page match, it shall use the procedure as defined in 2.6.2.3. If a match is declared, the mobile station shall set PAGED to YES.

  11. User Zone Identification Message: The mobile station shall process the parameters from the message (see 2.6.2.2.9).

  12. Private Neighbor List Message: The mobile station shall process the parameters from the message (see 2.6.2.2.10).

  13. Extended Global Service Redirection Message: The mobile station shall process the parameters from the message (see 2.6.2.2.11).

  14. Extended CDMA Channel List Message: The mobile station shall process the parameters from the message (see 2.6.2.2.12).

If the mobile station receives a message which is not included in the above list, the mobile station shall ignore the message.

When the stored configuration parameters are current (see 2.6.2.2) and CURR_ACC_MSG_SEQ and ACC_MSG_SEQs are equal and are not NULL, the mobile station shall disable the System Access State timer and shall do one of the following:

• If PAGED is equal to YES, the mobile station shall determine whether the message resulting in the page match was received on the current Paging Channel. If the message was received on the current Paging Channel, the mobile station shall enter the Page Response Substate; otherwise, the mobile station shall enter the Mobile Station Idle State.

• If this substate was entered with a page response indication and the mobile station has not performed an access entry handoff, the mobile station shall determine whether the message resulting in the page match was received on the current Paging Channel. If the message was received on the current Paging Channel, the mobile station shall enter the Page Response Substate; otherwise, the mobile station shall enter the Mobile Station Idle State.

• If this substate was entered with a page response indication and the mobile station has performed an access entry handoff, the mobile station shall enter the Page Response Substate.

• If this substate was entered with a page response retransmission indication, the mobile station shall enter the Page Response Substate.

• If this substate was entered with an origination indication, the mobile station shall enter the Mobile Station Origination Attempt Substate with an origination indication.

• If this substate was entered with a PACA response indication, the mobile station shall enter the Mobile Station Origination Attempt Substate with a PACA response indication.

• If this substate was entered with a Resource Control initiated new connection indication, the mobile station shall enter the Mobile Station Origination Attempt Substate with a Resource Control initiated new connection indication.

• If this substate was entered with a Resource Control initiated reconnect indication, the mobile station shall enter the Mobile Station Origination Attempt Substate with a Resource Control initiated reconnect indication.

• 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. If the message was received on the current Paging 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.

• If this substate was entered with an order/message response indication and the mobile station has performed an access entry handoff, the mobile station shall enter the Mobile Station Order/Message Response Substate.

• If this substate was entered with a registration indication, the mobile station shall enter the Registration Access Substate.

• If this substate was entered with a message transmission indication, the mobile station shall enter the Mobile Station Message Transmission Substate with a message transmission indication.

• If this substate was entered with a peer-to-peer resource control message initiation indication, the mobile station shall enter the Mobile Station Message Transmission Substate with a peer-to-peer resource control message initiation indication.

• If this substate was entered with a hook status indication, the mobile station shall enter the Mobile Station Message Transmission Substate with a hook status indication.

• If this substate was entered with a PACA cancel indication, the mobile station shall enter the PACA Cancel Substate.
