Mobile Station Order/Message Response Substate

2.6.3.4 Mobile Station Order/Message Response Substate

If a message received from the base station requires a Layer 2 acknowledgment and does not require a Layer 3 response, Layer 3 shall indicate to Layer 2 that no response is outstanding (see [4]).

If a message received from the base station requires a Layer 2 acknowledgment and also a Layer 3 response, Layer 3 shall indicate to Layer 2 that a response is outstanding (see [4]).

When transmitting a response to a message received from the base station, Layer 3 shall indicate to Layer 2 that the type of the message is a response (see [4]).

When transmitting an autonomous message (i.e., a message that is not sent as a response to a message received from the base station), Layer 3 shall indicate to Layer 2 that the type of the message is a request other than a registration request or a message transmission request (see [4]).

Upon entering the Mobile Station Order/Message Response Substate, the mobile station shall send the response message.

While in this substate, the mobile station shall monitor the Paging Channel or the Forward Common Control Channel. If the mobile station declares a loss of the Paging Channel or the Forward Common 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 disable its transmitter.

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

If the mobile station receives confirmation of delivery of any message sent by the mobile station in this substate, it shall send a response in this substate if required, and shall then 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 the mobile station is to exit the System Access State as a result of processing Layer 3 fields of a message requiring an acknowledgment, the mobile station shall exit the System Access State after Layer 3 receives an indication from Layer 2 that the acknowledgment to the message has been sent and acknowledged.

If Layer 3 receives a message with an indication from Layer 2 that an access attempt for a message being transmitted was not terminated as a result of processing the Layer 2 fields of the received message, the mobile station shall ignore the received message.

The following directed messages and orders can be received. If any field value of the message or order is outside its permissible range, the mobile station may send a Mobile Station Reject Order with ORDQ equal to ‘00000100’ (message field not in valid range).

1. Authentication Challenge Message: The mobile station shall respond to the message as specified in 2.3.12.1.4, regardless of the value of AUTH_s.

The mobile station should notify the user of the locked condition. The mobile station shall 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.
   
8. 
   Maintenance Required Order: The mobile station shall record the reason for the Maintenance Required Order in the mobile station’s semi-permanent memory (MAINTRSN_s p equals the least significant four bits of ORDQ_r).

   Registration Accepted Order: The mobile station shall perform the procedures as specified in 2.6.11.1.
   
10. 
    Registration Rejected Order: This order indicates that normal service is not available on this system. The mobile station shall disable the full-TMSI timer. If the received order specifies to delete the TMSI (ORDQ = ‘00000100’), the mobile station shall set all the bits of the TMSI_CODE_s-p to ‘1’. The mobile station shall enter the System Determination Substate of the Mobile Station Initialization State with a registration rejected indication (see 2.6.1.1).
    
11. 
    Retry Order: The mobile station shall process the message as follows:
    

• If RETRY_TYPE_r is equal to ‘001’, ‘100’, or ‘101’, the mobile station shall perform the following:

 If RETRY_DELAY_r is equal to ‘00000000’, then the mobile station shall set RETRY_DELAY_s[RETRY_TYPE_r] to 0.

 If RETRY_DELAY_r is not equal to ‘00000000’, the mobile station shall set RETRY_DELAY_s[RETRY_TYPE_r] as follows:

+ If the most significant bit of the RETRY_DELAY_r is ‘0’, set RETRY_DELAY_UNIT_s to 1000ms. If the most significant bit of the RETRY_DELAY_r is ‘1’, set RETRY_DELAY_UNIT_s to 60000ms.

+ The mobile station shall set RETRY_DELAY_VALUE_s to the seven least significant bits of RETRY_DELAY_r.

If P_REV_IN_USE_s is less than or equal to three, the mobile station shall respond with a Status Response Message. If P_REV_IN_USE_s is greater than three, the mobile station shall respond with an Extended Status Response Message. If the message does not specify any qualification information (QUAL_INFO_TYPE_r is equal to ‘00000000’), the mobile station shall include the requested information records in the response. If the message specifies a band class (QUAL_INFO_TYPE_r is equal to ‘00000001’), the mobile station shall only include the requested information records for the specified band class (BAND_CLASS_r) in the response. If the message specifies a band class and an operating mode (QUAL_INFO_TYPE_r is equal to ‘00000010’), the mobile station shall only include the requested information records for the specified band class (BAND_CLASS_r) and operating mode (OP_MODE_r) in the response. If the message specifies a band class or a band class and an operating mode which is not supported by the mobile station, the mobile station shall send a Mobile Station Reject Order with ORDQ set to ‘00000110’ (message requires a capability that is not supported by the mobile station). If the response to this message exceeds the allowable length, the mobile station shall send a Mobile Station Reject Order with ORDQ set to ‘00001000’ (response message would exceed the allowable length). If the message specifies an information record which is not supported by the mobile station for the specified band class and operating mode, the mobile station shall send a Mobile Station Reject Order with ORDQ set to ‘00001001’ (information record is not supported for the specified band class and operating mode).
