8.2 AT+COPS Operator Selection
AT+COPS queries the present status of the EHS6's network registration and allows to determine whether auto-
matic or manual network selection shall be used.
Three operator selection modes are available:
• Automatic
EHS6 searches for the home operator automatically. If successful the EHS6 registers to the home network.
If the home network is not found, EHS6 goes on searching. If a permitted operator is found, EHS6 registers
to this operator.
If no operator is found the EHS6 remains unregistered.
• Manual
Desired operator can be determined using the AT+COPS write command. If the operator is found, EHS6 reg-
isters to it immediately. If the selected operator is forbidden, the EHS6 remains unregistered.
• Manual/automatic
The ME first tries to find the operator determined via AT+COPS write command. If the ME fails to register to
this operator, then it starts to select another (permitted) operator automatically.
The AT+COPS test command consists 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,
• short alphanumeric format of the operator's name,
• numeric format representation of the operator.
• an integer indicating the acccess technology of the operator.
The list of operators comes in the following order: Home network, networks referenced in SIM and other net-
works.
The AT+COPS read command returns the current <mode> and the currently selected operator. If no operator is
selected, <format> and <opName> are omitted.
The AT+COPS write command forces an attempt to select and register to the network operator. If the selected
operator is not available, no other operator will be selected (except <mode>=4). The selected operator name
<format> will apply to further read commands, too.
Command settings are effective over all serial interfaces of the EHS6.
