AT+COPS Operator Selection
queries the present status of the BGS2T's network registration and allows to determine whether auto-
matic or manual network selection shall be used. Additional service is available with
.
Three operator selection modes are available:
•
Automatic
BGS2T searches for the home operator automatically. If successful the BGS2T registers to the home net-
work. If the home network is not found, BGS2T goes on searching. If a permitted operator is found, BGS2T
registers to this operator.
If no operator is found the BGS2T remains unregistered.
•
Manual
Desired operator can be determined using the
write command. If the operator is found, BGS2T reg-
isters to it immediately. If the selected operator is forbidden, the BGS2T remains unregistered.
•
Manual/automatic
The ME first tries to find the operator determined via
write command. If the ME fails to register to
this operator, then it starts to select another (permitted) operator automatically.
The
test command conists of several parameter sets, each representing an operator present in the
network.
Each set contains the following information:
•
an integer indicating the availability of the operator,
•
long alphanumeric format of the operator's name and
•
numeric format representation of the operator.
Any of the parameters may be unavailable and will then be an empty field (,,). The list of operators comes in the
following order: Home network, networks referenced in SIM and other networks.
The operator list is followed by a list of the supported
s and
s. These lists are delimited from
the operator list by two commas.
If the test command is used during an ongoing GPRS transfer, traffic will be interrupted for up to one minute.
The
read command returns the current
and the currently selected operator. If no operator is
selected,
and
are omitted.
The
write command forces an attempt to select and register to the GSM network operator (see note
below). If the selected operator is not available, no other operator will be selected (except
=4). The
selected operator name
will apply to further read commands, too.
Command settings are effective over all serial interfaces of the BGS2T.
