Network Service Commands TRM250
Network Service Commands
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.
The command returns the current operators and their status, and allows setting automatic or manual network selection.
The command indicates the received signal strength <rssi> and the channel bit error rate <ber>.
The command returns the status of MT indicators
The commanded its and queries the list of preferred operators.
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.
The Write Command enables and disables automatic time zone update via NITZ. The configuration is stored to NV automatically.
The Write Command controls the setting of the UE’s power saving mode (PSM) parameters.
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.
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.
The command is also used for PSM setting, and it is mainly used to set extended parameters for modem optimizations.
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 This means that the current state may be out of date.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.
The Write Command controls the setting of the UE’s e-I-DRX (extended idle mode DRX) 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.
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.
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.
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.
