40 Network service commands 6615-2220
+WOPN – Read operator name
Description:
This command returns the operator name in alphanumeric format when given the
numeric format.
With E-ONS (Enhanced Operator Name Service) feature, <lac> is an optional parameter
to read names from OPL/PNN sim files. If it is not entered, name will be given with cur-
rent lac. Note that in limited service, current lac is set to 0.
It also permits to erase NITZ PLMN names stored in Flash memory with "AT
+WOPN=3,0".
When the modem receives a NITZ (Network Information and Time Zone) mes-
sage with Long Name or Short Name information, an entry with registered PLMN
and names in message is created in flash memory. These names will then be used with
+COPS,+COPN,+WOPN commands with the priority order defined in 3GPP TS 22.101.
The modem supports only network names with GSM default alphabet coding scheme.
The user can choose which of the following method will be used for getting PLMN
names with command “AT+WOPN=4,<PlmnOns>”
The Priority order is:
1 – E-ONS First entry if on Home PLMN, or matching entry if existing in OPL/
PNN SIM files.
2 – CPHS If on home PLMN, use SIM file CPHS ONS (0x6F46) for Long Name
if present (if not, reuse SIM file CPHS ONS)
3 – SPN If on home PLMN, use SIM file SPN (0x6F46) if present.
4 – NITZ If there’s a matching entry in the list of names received so far use
it. Note that in France for example, all the operators use NITZ
message for date and time feature, but not for PLMN names, so
the list is always empty. In France, NITZ message is sent on GPRS
attachment. If there’s a matching entry in flash PLMN list (created by
+WOLM), use it.
5 – ROM PLMN names in ROM defined according to MoU SE.13 and NAPRD
Operator Names documents.
Once a long name is found following this priority order, it is given as response to AT
command.
Refer to 3GPP TS 24.008 V5.3.0, 3GPP TS 23.040 v6.1.0, 3GPP TS 22.042 v5.0.0 for more
information.
