The contents of this field are a compact form of the UTC Time format containing local time plus an
offset to universal time. Binary coded decimal encoding is employed for the digits to reduce the
storage and transmission overhead.

storage and transmission overhead.
-- e.g. YYMMDDhhmmssShhmm
-- where
-- YY = Year 00 to 99 BCD encoded
-- MM = Month 01 to 12 BCD encoded
-- DD = Day 01 to 31 BCD encoded
-- hh = hour 00 to 23 BCD encoded
-- mm = minute 00 to 59 BCD encoded
-- ss = second 00 to 59 BCD encoded
-- S = Sign 0 = “+”, “-” ASCII encoded
-- hh = hour 00 to 23 BCD encoded
-- mm = minute 00 to 59 BCD encoded

User Location Information
This field contains the User Location Information as described in TS 29.274 for eGTP cases (e.g. CGI, SAI,
RAI, TAI and ECGI).

The field is provided by the SGSN/MME and transferred to the S-GW/P-GW during the IP-CAN
bearer activation/modification.

User Location Information contains the location (e.g. CGI/SAI, ECGI/TAI or RAI) where the UE
is located and used during the transfer of the data volume captured by the container (applicable
only to the SGW-CDR). This is included in the Traffic data container only if previous container's
change condition is “user location change”. Note the user location information in SGW-CDR main
level contains the location where the UE was when CDR was opened.

only to the SGW-CDR). This is included in the Traffic data container only if previous container's
change condition is “user location change”. Note the user location information in SGW-CDR main
level contains the location where the UE was when CDR was opened.
In the below example there are five containers. In the third container the CGI/SAI is changed. So as
per the definition above since the CGI/SAI is changed, the next container should have ULI
information. The fourth container has the ULI information.
