4.23.1 Call duration in UTRAN cell for CS domain

1. This measurement provides the call duration in utran cell for CS domain. The measurement is split into subcounters per traffic class (See the 3GPP TS23.107 [2]).
2. DER (n=1)
3. This measurement is obtained by accumulating the time intervals for each traffic class between the call start RRC RADIO BEARER SETUP COMPLETE and the call completed RRC RADIO BEARER RELEASE over a granularity period using DER, For conversational service, the relevant measurement for each specified data rate is required, the detailed data rates are listed below (see TS 25.993 [12]).The accumulator shall be reinitialised at the beginning of each granularity period. The call duration for each traffic class (for each specified data rate of conversational service) for CS domain is added to the relevant measurement. See TS 25.413 [5] and TS 23.107 [2].
   uplink <U>:
   1: AMR rate (12.2 10.2 7.95 7.4 6.7 5.9 5.15 4.75) kbps
   2: 12.2 kbps
   3: 28.8 kbps

   downlink <D>:
   1: AMR rate (12.2 10.2 7.95 7.4 6.7 5.9 5.15 4.75) kbps
   2: 12.2 kbps
   3: 28.8 kbps
   4: 32 kbps
   5: 64 kbps
   As indicated above, <U> and <D> are integer values that map to the conversational service specified uplink and downlink data rates, respectively.
4. Each measurement is an integer value. (in seconds)
5. The measurement name has the form
   RRC.CallDurationCS.Conv.<U><D>
   RRC.CallDurationCS.Strm
   RRC.CallDurationCS.Intact
   RRC.CallDurationCS.Bgrd.
