Chapter 8. Network Service
Commands
The AT Commands described in this chapter are related to various network services. More commands related to this
area can be found in Chapter 9., Supplementary Service Commands.
8.1 AT+COPN Read Operator Names
Description: The AT+COPN command returns the list of operator names from the ME. Each operator
code <numericn> that has an alphanumeric equivalent <alphan> in the ME memory is
returned. See also: AT^SPLM.
Test Command Syntax: AT+COPN=?
Response: OK
ERROR
+CME ERROR
Exec Command Syntax: AT+COPN
Response: +COPN: <numericn>, <alphan>
+COPN: ...
OK
ERROR
+CME ERROR
Parameter Descriptions:
<numericn>
Operator in numeric format; GSM location area identification number.
<alphan>
Operator in long alphanumeric format; can contain up to 16 characters.
8.2 AT+COPS Operator Selection
Description: AT+COPS queries the present status of the Multi-Tech wireless modem’s network registration
and allows to determine whether automatic or manual network selection shall be used.
Additional service is available with AT^SOPS.
Three operator selection modes are available:
• Automatic
The Multi-Tech wireless modem searches for the home operator automatically. If successful
the Multi-Tech wireless modem registers to the home network.
If the home network is not found, the Multi-Tech wireless modem goes on searching. If a
permitted operator is found, the Multi-Tech wireless modem registers to this operator.
If no operator is found the Multi-Tech wireless modem remains unregistered.
• Manual
Desired operator can be determined using the AT+COPS write command. If the operator is
found, the Multi-Tech wireless modem registers to it immediately. If the selected operator is
forbidden, the Multi-Tech wireless modem remains unregistered.
• Manual/automatic
The ME first tries to find the operator determined via AT+COPS write command. If it 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 AT+COPS 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 <mode>s and
<format>s. These lists are delimited from the operator list by two commas.
