Served MSISDN
This field tracks the Mobile Station (MS) ISDN number (MSISDN) of the subscriber which is transparently copied from the
Create Session Request message.
Create Session Request message.
The MSISDN is TBCD encoded as shown in the example below:
3GPP TS 23.003 (CCITT Rec. E 213)
ServedMSISDN ::= OCTET STRING (SIZE(1..9))
MSISDN in CDR is 1:1 copy of the MSISDN sent in GTP-V2 message. MSISDN value contains only the actual
MSISDN number (does not contain the “nature of address indicator” octet, which indicates “international number” as
in 3GPP TS 29.002) and is encoded as TBCD digits (i.e. digits from 0 through 9 are encoded “0000” to “1001”).
When there is an odd number of digits, bits 8 to 5 of the last octet are encoded with the filler “1111”.

Served PDP PDN Address
This field contains the IP address for the PDN connection (PDP context, IP-CAN bearer) if available. This is a network layer
address of type IP version 4 (PDN Type is IPv4) or IP version 6 (PDN Type is IPv6 or IPv4v6). The address for each bearer
type is allocated either temporarily or permanently (see “Dynamic Address Flag”). This parameter is present except when both
the bearer type is PPP and dynamic address assignment is used.

type is allocated either temporarily or permanently (see “Dynamic Address Flag”). This parameter is present except when both
the bearer type is PPP and dynamic address assignment is used.
NOTE: IP address allocated for the PDP context / PDN connection, if available, i.e. IPv4 when PDN Type is IPv4 or
IPv6 when PDN Type is IPv6 or IPv4v6.
IPv6 when PDN Type is IPv6 or IPv4v6.
Format
