bit 4..1 : numbering plan indicator
= 0001: ISDN/Telephony Numbering Plan (Rec CCITT E.164)
other : not relevant
octet 2..9: <= 16 digits TBCD-String (twisted)
substructure (without spares or fillers):
1..3 digits - country code (CC)
(only international number)
3 digits - national destination code (NDC)
<= 10 digits - subscriber number (SN)
first and intermediate octet = 2 digits
last octet = 2 digits or 1 digit + 1 fill digit H'F
As per 3GPP TS 29.274 v 8.11.0, “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 [37]) and is encoded
as TBCD digits.”
‘nature of address indicator’ octet, which indicates ‘international number’ as in 3GPP TS 29.002 [37]) and is encoded
as TBCD digits.”
To comply with this, octet 1 (nature of address indicator) is not added in the encoded value of MSISDN.
For example:
MSISDN: '491720400305'
encoded: H'94 71 02 04 30 50
Format
BCD encoded octet string.

Served PDP PDN Address
This field contains the IP address for the PDN connection (PDP context, IP-CAN bearer). 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 shall be present except when both
the Bearer type is PPP and dynamic address assignment is used.
