GSR6 A one phase channel request is received. An Enhanced One–Phase (EOP) access indication is received. A Packet Resource Request (PRR) message is received. A Packet Downlink Ack/Nack (PDAK) message is received. CHANNEL_REQS_SUCCESS This statistic pegs each time a PACKET UPLINK ASSIGNMENT message is sent to the mobile. Retransmissions are not pegged. This statistic pegs when: A one phase Immediate Assignment (IA) is sent. An Enhanced One–Phase (EOP) access indication is received. A Packet Uplink Assignment (PUA) is initially sent to establish the Temporary Block Flow (TBF). A Packet Timeslot Reconfigure (PTR) is initially sent to establish an uplink TBF when a downlink TBF is in progress. IMM_ASSGN_CAUSE This statistic measures the successful immediate assignment procedures, per cause. This statistic is obtained by measuring the number of IMMEDIATE ASSIGN COMMAND messages transmitted, per cause. This message contains either an IMMEDIATE ASSIGNMENT message or IMMEDIATE ASSIGNMENT EXTENDED message. If an IMMEDIATE ASSIGNMENT EXTENDED message is transmitted, the counter is incremented by two, because it contains assignment information for two MSs otherwise the counter is incremented by one. The associated bins, identifiers and establishment causes are as follows: MS_CLASS_REQ The MS_CLASS_1_10_REQ statistic tracks the number of requests received for the MS classes 1 through 10. The MS_CLASS_11_20_REQ statistic tracks the number of requests received for the MS classes 11 through 20. The MS_CLASS_21_29_REQ statistic tracks the number of requests received for the MS classes 21 through 29.
