High AAL2 Failures in E\\

[raghchau]

Hi,

In interesting case study of high AAL2 fails is attached.

Hope it would be useful to all of u.

AAL2 resources availability in RNC (M800) RNC_602a
AAL2 resource reservation success rate [%] :

The transport resource request success ratio [%] KPI describes the average success rate of the transport resource reservation attempts for all AAL2 type connections

AAL2_SUCCEEDED - AAL2 signaling requests which have been successfully executed in A2SP

AAL2_REJECTED - AAL2 signaling requests which have failed for any reason. E.g. signaling failed or uplink CAC reject
RES_EXT_CAP - Transport resources requests which are rejected by downlink CAC since there is not enough capacity in the external AAL2 path.

RES_INT_CAP - Resource reservations which are rejected by downlink CAC since there are no RNC-internal AAL2 processing resources available

RES_OTHER - Resource reservations which have failed for any other reason than CAC or signaling (for example route analysis, parameter or DSP resource allocation problem)
