Sem pogledal. V specifikaciji: https://www.3gpp.org/ftp/Specs/archive/04_series/04.08/0408-520.ZIP je prvič omenjen netowrk name kot tak. (Zelo težko iskat po vseh teh ZIPih, ne vem zakaj ni to kako drugače. Anyway).
Na strani 228 je napisano tole:
9.2.15a.1 Full name for network
This IE may be sent by the network. If this IE is sent, the contents of this IE indicate the “full length name of the network” that the network wishes the mobile station to associate with the MCC and MNC contained in the Location Area Identification of the cell to which the mobile station sent its Channel Request message.
9.2.15a.2 Short name for network
This IE may be sent by the network. If this IE is sent, the contents of this IE indicate the “abbreviated name of the network” that the network wishes the mobile station to associate with the MCC and MNC contained in the Location Area Identification of the cell to which the mobile station sent its Channel Request message.
10.5.3.5a Network Name
The purpose of this information element is to pass a text string to the mobile station.
The Network Name information element is coded as shown in Figure 10.65a/GSM 04.08 and Table 10.65a/GSM 04.08.
The Network Name is a type 4 information element with a minimum length of 3 octets. No upper length limit is specified except for that given by the maximum number of octets in a L3 message (see TS GSM 04.06).

Number of spare bits in last octet (octet 3, bits 1 to 3)
0 0 1 bit 8 is spare and set to '0' in octet n
0 1 0 bits 7 and 8 are spare and set to '0' in octet n
0 1 1 bits 6 to 8(inclusive) are spare and set to '0' in octet n
1 0 0 bits 5 to 8(inc)are spare and set to '0' in octet n

0 0 0 this field carries no information about the number of spare bits in octet n
Add CI (octet 3, bit 4)
0 The mobile station should not add the letters for the Country's Initials to the text string
1 The mobile station should add the letters for the Country's Initials and a separator (e.g. a space) to the text string

Prva prava Nokia 3310 je bila predstavljena septembra 2000, med tem ko Ericcson G828, ki ga imam jaz Maj 1996. Torej je logično kar se dogaja!
