Does anybody know what the reason for the abnormal realease connection is? In Tems investigation there is only the reason RR cause.Thankse in advance.
it can be anything, isn’t it ? interference, coverage, abis link failures, TC failures, etc…
tems doesn’t give any detail when a call drop occurs.if you mean Ericsson, it may be due to battery running out of energy or no pre paid credits, for example. Also due to “sudden” loss of conections (entering elevator, e.g, when no message is received from BSC)
If you have AMR implemented on your network, might need to increase RLINKT to make SACCH more robust especially on cell fringes.
some operator restrict to this parameter (Radio Link Timeout) 😀
