Rcvd from GGSN through RNC
|
Description: This
proprietary counter indicates the total number of error indication
messages from GGSN.
If direct tunnel is
enabled, data flows between RNC and GGSN. When the RNC receives GTPU-PDU
from the GGSN for which no RAB context exists, RNC discards GTPU-PDU
and returns error indication to GGSN. In order to notify SGSN, GGSN
sends UPC request with EI Flag to SGSN.
Triggers: Increments
when SGSN receives error indication messages from GGSN through RNC.

Rcvd from RNC through GGSN
|
Description: This
proprietary counter indicates the total number of error indication
messages from RNC.
If direct tunnel is
enabled, data flows between RNC and GGSN. GGSN sends Error indication
to RNC, and in order to notify SGSN, RNC sends RAB Release Request
with the error cause 'GTP Resources Unavailable'.
Triggers: Increments
when SGSN receives error indication messages from GGSN through RNC.
This is when SGSN receives (Error indication message) Update PDP Context
request with EI (Error Indication) flag from GGSN.
