AT+COPS Operator Selection
queries the present status of the TC63's network registration and allows to determine whether auto-
matic or manual network selection shall be used. Additional serviceis available with
Three operator selection modes are available:
• Automatic
TC63 searches for the home operator automatically. If successful the TC63 registers to the home network. If
the home network is not found, TC63 goes on searching. If a permitted operator is found, TC63 registers to
this operator.
If no operator is found the TC63 remains unregistered.
• Manual
Desired operator can be determined using the
write command. If the operator is found, TC63 reg-
isters to it immediately. If the selected operator is forbidden, the TC63 remains unregistered.
• Manual/automatic
The ME first tries to find the operator determined via
write command. If the is able to register to this
operator, it enters the manual operator selection mode. If the ME cannot find this operator or fails to register
to this operator, then it enters the automatic operator selection mode and starts to select the home operators
network or another (permitted) one.
The most recently entered operator selection mode is still valid after the ME was restarted (power-off/on).
The
test command lists sets of four parameters, each representing an operator present in the network.
A set consists of
• 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 TC63.
