Network Service Commands TRM250
Network Service Commands
AT+CREG Network Registration
The Write Command controls the presentation of the unsolicited result code +CREG: <stat> when <n>=1 and there is a change in the MT’s circuit mode network registration status in GERAN/E-UTRAN, or unsolicited result code +CREG: <stat>[,[<lac>],[<ci>],[<AcT>]] when <n>=2 and there is a change of the network cell in GERAN/E-UTRAN.
AT+COPS Operator Selection
The command returns the current operators and their status, and allows setting automatic or manual network selection.
AT+CSQ Signal Quality Report
The command indicates the received signal strength <rssi> and the channel bit error rate <ber>.
AT+CIND Indicator Control
The command returns the status of MT indicators
AT+CPOL Preferred Operator List
The commanded its and queries the list of preferred operators.
AT+COPN Read Operator Names
The 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.
AT+CTZU Automatic Time Zone Update
The Write Command enables and disables automatic time zone update via NITZ. The configuration is stored to NV automatically.
AT+CPSMS Power Saving Mode Setting
The Write Command controls the setting of the UE’s power saving mode (PSM) parameters.
AT+QPSMS Power Saving Mode Setting
Quectel extended AT command for PSM setting. The Write Command controls the setting of BG96’s power saving mode (PSM) parameters. It is similar with AT+CPSMS.
AT+QPSMCFG PSM Feature and Minimum Threshold Value Setting
This command is used to set NV#73769 (PSM configuration) parameters. Customers can use this AT command to enable or disable PSM function and set the minimum threshold value to enter PSM.
AT+QPSMEXTCFG Modem Optimization
The command is also used for PSM setting, and it is mainly used to set extended parameters for modem optimizations.
AT+QCSCON Signaling Connection Status
The command gives details of the terminal’s perceived radio connection status. It returns an indication of the current state. Please note that this state is only updated when radio events, such as sending and receiving, take place. This means that the current state may be out of date. The terminal may think it is "Connected" yet cannot currently use a base station due to a change in the link quality.
AT+CEDRXS e-I-DRX Setting
The Write Command controls the setting of the UE’s e-I-DRX (extended idle mode DRX) parameters.
AT+CEDRXRDP Read Dynamic Parameters
The Execution Command returns <AcT-type>, <Requested_eDRX_value>, <NW-provided_eDRX_value> and <Paging_time_window> if e-I-DRX is used for the cell that the MS is currently registered to.
AT+CTZR Time Zone Reporting
This command controls the time zone reporting of changed event. If reporting is enabled, the MT returns the unsolicited result code +CTZV: <tz> or +CTZE: <tz>,<dst>, whenever the time zone is changed. The configuration is stored to NV automatically.
AT+QLTS Obtain the Latest Time Synchronized Through Network
The command is used to obtain the latest time synchronized through network.

The command indicates network information such as the access technology selected, the operator, and the band selected.
AT+QCSQ Query and Report Signal Strength
The command is used to query and report the signal strength of the current service network. If the MT is registered on multiple networks in different service modes, customers can query the signal strength of networks in each mode. No matter whether the MT is registered on a network or not, the command can be run to query the signal strength or allow the MT to unsolicitedly report the detected signal strength if the MT camps on the network. If the MT is not using any service network or the service mode is uncertain, "NOSERVICE" will be returned as the query result.
