Usually situation may be due to the lost contact, the UE and the

network side initiates a service, or the user to re-enable the UE to

re-initiate the RRC connection, and the RNCside is not the user

resource release. Also a small part of the reason is lead by

the DSCR, in LCR 5.0 advised to turn off the DSCR function.

23G switch (or RNC switch between) failed in the RNC the

If 23G switch (or RNC switch between) success, UE and rapid

the release.

Whether in the then system dropped calls, you need to see

whether IU REL REQ message, if not is not counted as dropped

calls; IU REL REQ message, but the carrying value of the reason is

the normal release, does not count as a dropped call .
