Cause

The RR procedure has not established the radio connection. A Channel request has been sent, but there has been

no response from the network. Cell seriously congesting.

Cell overshooting.

The RR procedure has not established the radio connection. A Channel request has been sent, but there has been

no response from the network.

Interference with strong signal - possible radio planning issues on cell 36317 (with BCCH 664 and BSIC 47)

No strong cells in area - signal strength should be greater than -95 dBm but signal prior to call setup failure was -

101 dBm

675-60 ~ 79-40

Overshooting cell

suspected swap on T3658

An excessive power down request was performed on the handset - check the power hysteresis settings in the BSS

configuration.
