Description
Decode Failure
Description: This proprietary counter indicates the total number of SN-PDUs dropped at
SNDCP due to decode failure.
Triggers: Increments when Decode failures occur for SN-PDUs.
Availability: per SGSN service
SNDCP due to decode failure.
Triggers: Increments when Decode failures occur for SN-PDUs.
Availability: per SGSN service
Reassembly Drops:
Discard State
Description: This proprietary counter indicates the total number of SN-PDUs dropped at
SNDCP in discard state.
Triggers: Increments when SN-PDUs are dropped and an unexpected segment is received to
enter discard state. SNDCP entity expects either a first segment or subsequent segment.
Reception of last segment clears this state.
Availability: per SGSN service
SNDCP in discard state.
Triggers: Increments when SN-PDUs are dropped and an unexpected segment is received to
enter discard state. SNDCP entity expects either a first segment or subsequent segment.
Reception of last segment clears this state.
Availability: per SGSN service
Rx First Seg
State
State
Description: This proprietary counter indicates the total number of SN-PDUs dropped at
SNDCP in Receive First Segment state.
Triggers: In receive first segment state, only first segment of N-PDU is expected. If
subsequent segmented is received, it is dropped with this reason and enters discard state.
Availability: per SGSN service
SNDCP in Receive First Segment state.
Triggers: In receive first segment state, only first segment of N-PDU is expected. If
subsequent segmented is received, it is dropped with this reason and enters discard state.
Availability: per SGSN service
Rx Subsequent
Seg State
Seg State
Description: This proprietary counter indicates the total number of SN-PDUs dropped at
SNDCP due to reassembly failure.
Triggers: In receive subsequent segment state, only subsequent segments of N-PDU are
expected. If first segment is received, it is dropped with this reason and enters discard state.
Availability: per SGSN service
SNDCP due to reassembly failure.
Triggers: In receive subsequent segment state, only subsequent segments of N-PDU are
expected. If first segment is received, it is dropped with this reason and enters discard state.
Availability: per SGSN service
New First
Segment
Segment
Description: This proprietary counter indicates the total number of buffered SN-PDUs
dropped at SNDCP due to reception of new N-PDU.
Triggers: Increments when reception of new N-PDU drops buffered SN-PDUs, if any with
this reason.
Availability: per SGSN service
dropped at SNDCP due to reception of new N-PDU.
Triggers: Increments when reception of new N-PDU drops buffered SN-PDUs, if any with
this reason.
Availability: per SGSN service
Reassembly
Failure
Failure
Description: This proprietary counter indicates the total number of SN-PDUs dropped at
SNDCP due to reassembly failure.
Triggers: Increments when SN-PDUs are dropped at SNDCP due to reassembly failure.
Availability: per SGSN service
SNDCP due to reassembly failure.
Triggers: Increments when SN-PDUs are dropped at SNDCP due to reassembly failure.
Availability: per SGSN service
Reassembly
Timeout
Timeout
Description: This proprietary counter indicates the total number of SN-PDUs dropped at
SNDCP due to reassembly timeout.
Triggers: Increments when the buffered segments are dropped and the last segment is not
received before reassembly timer expiry.
Availability: per SGSN service
SNDCP due to reassembly timeout.
Triggers: Increments when the buffered segments are dropped and the last segment is not
received before reassembly timer expiry.
Availability: per SGSN service
DCOMP Error
Description: This proprietary counter indicates the total number of SN-PDUs dropped at
SNDCP due to DCOMP (Data Compression algorithm ID) error.
Triggers: Increments when SN-PDUs are received with invalid DCOMP value or DCOMP
value different from that negotiated between MS and SGSN.
Availability: per SGSN service
SNDCP due to DCOMP (Data Compression algorithm ID) error.
Triggers: Increments when SN-PDUs are received with invalid DCOMP value or DCOMP
value different from that negotiated between MS and SGSN.
Availability: per SGSN service
