Type-of-address of the sender number (SMS)

I would like to know what kind of type-of-address of the sender number exist. For example, the PDU below contains 91 type-of-address:

07919742020096F6400B919742039333F7

91 means international format of the phone number and I have to add + before this number. Sometimes I face type-of-address such as D0, C8 and so on. So what do they mean? Where can I find information about it? Thanks in advance.

--UPDATED--

I have found the program called PDUspy. It can recognise type-of-address. So I have found that D0 - Alpha (acc. to TS 03.38) and the number is represented as text, for example Nikolas. C8 - subscriber number. But what do they mean and how to parse these numbers depending on its type?

The number is represented as text, you can decode it with 7bit type. CEF4FACD0ECF01=Nikolas

The TON/NPI information can be found on section 9.1.2.5 of 3GPP TS 23.040. The address value (phone number) are BCD left coded, padded with optional 'F' to make it even and then swapped.

Example of parsing the APDU data from an SMS proactive command (also need to refer to 3GPP TS 11.14)

D0 16 81 03 06 13 01 82 02 81 83 0B 0B 01 00 03 81 00 F7 00 F2 02 70 6C
