This message is sent on the PCCCH or PACCH by the network to the mobile station to indicate that the network has rejected the MSs access request. This message may contain fields addressing more than one mobile station.

Message type: PACKET ACCESS REJECT

Direction: network to mobile station

Classification: distribution message

Table 11.2.1.2: Packet ACCESS REJECT information element details

PAGE_MODE (2 bit field)
This field is defined in sub-clause 12.20.

Reject struct
The mobile station shall only accept the first Reject struct addressed to it and ignore all other Reject structs.

Packet Request Reference
This information element shall be included if the PACKET ACCESS REJECT message is sent in response to a PACKET CHANNEL REQUEST message. This information element is defined in sub-clause 12.11.

TLLI (32 bit field)
This information field shall be included if the PACKET ACCESS REJECT message is sent in response to a PACKET RESOURCE REQUEST message or a Channel Request Description IE contained in a PACKET DOWNLINK ACK/NACK message. This information field is defined in sub-clause 12.16.

Global TFI
This information element contains the TFI of the mobile station’s downlink TBF or uplink TBF. This field is defined in sub-clause 12.10.

WAIT_INDICATION (8 bit field)
The Wait Indication field indicates the time the mobile station shall wait before attempting another channel request. This field is coded as the binary representation of the T3172 timeout value in units of 20 milliseconds or in units of seconds. The units are indicated in the WAIT_INDICATION_SIZE field.
Range 0 to 255.

WAIT_INDICATION_SIZE (1 bit field)
This field indicates the units of the WAIT_INDICATION field.

0 the WAIT_INDICATION field is coded in units of seconds
1 the WAIT_INDICATION field is coded in units of 20 milliseconds
