Cops Operator Selection - Nokia 30 GSM Connectivity Terminal At Command Manual

7.2 +COPS OPERATOR SELECTION

Command
Set +COPS=<mode>,
<format>,<oper>
Read +COPS?
Test +COPS=?
The +COPS command forces an attempt to select and register the GSM network operator.
<mode> is used to select whether the selection is automatically carried out by the Nokia 30
or whether it is forced by this command to the operator <oper>, given in numeric 2 <format>.
The selected operator name format shall also apply to the further read commands
(+COPS?).
The read command returns the current mode and the currently selected operator. If no
operator is selected, <format> and <oper> are omitted.
The test command returns a list of quadruplets, each representing an operator that is present
in the network. A quadruplet consists of an integer indicating the availability of the operator
<stat> and a numeric representation of the operator. The list of operators should be in the
following order: home network, networks referenced in SIM and other networks.
After the operator list is returned, the Nokia 30 returns lists of the supported <mode> and
<format>. These lists shall be delimited from the operator list by two commas.
Defined values
<mode>:
0
1
<format>:
2
<oper> The numeric format is the GSM Location Area Identification number (refer to
GSM 04.08 10.5.1.3) which consists of a three BCD digit country code coded
as in ITU-T E.212 Annex A, plus a two BCD digit network code, which is
administration-specific; a returned <oper> shall not be in Binary Coded Decimal
(BCD) format, but in IRA characters converted from BCD; hence the number
has the following structure: (country code digit 3)(country code digit 2)(country
code digit 1)(network code digit 2)(network code digit 1)
