F0401   AT+CREG        Network Registration

This command is used to control the presentation of an unsolicited result code +CREG: <stat> when <n>=1

and there is a change in the ME network registration status or code +CREG: <stat>[,<lac>,<ci>] when <n>=2 and there is a change of the network cell.

Read command returns the status of result code presentation and an integer <stat>

which shows whether the network has currently indicated the registration of the ME.

Location information elements <lac> and <ci> are returned only when <n>=2 and ME is registered in the network.

F0402   AT+COPS      Operator Selection

Write command forces an attempt to select and register the GSM/UMTS network operator.

<mode> is used to select whether the selection is done automatically by the ME or is forced by this command to operator

<oper> (it shall be given in format <format>). If the selected operator is not available,

no other operator shall be selected (except <mode>=4).

The selected operator name format shall apply to further read commands (AT+COPS?) also.

<mode>=2 forces an attempt to deregister from the network.

The selected mode affects to all further network registration (e.g. after <mode>=2,

ME shall be unregistered until <mode>=0 or 1 is selected).

Read command returns the current mode and the currently selected operator.

If no operator is selected, <format> and <oper> are omitted.

 

Test command returns a list of quadruplets, each representing an operator present in the network.

Quadruplet consists of an integer indicating the availability of the operator <stat>,

long and short alphanumeric format of the name of the operator,

and numeric format representation of the operator.Any of the formats may be unavailable and should then be an empty field.

The list of operators shall be in order: home network, networks referenced in SIM, and other networks.

It is recommended (although optional) that after the operator list TA returns lists of supported <mode>s and

<format>s. These lists shall be delimited from the operator list by two commas.

 F0414   AT+CEREG       EPS Network Registration Status

The set command controls the presentation of an unsolicited result code +CEREG: <stat> when <n>=1

and there is a change in the MT’s EPS network registration status in E-UTRAN, or unsolicited result code

+CEREG: <stat>[,<tac>,<ci>[,<AcT>]] when <n>=2 and there is a change of the network cell in E-UTRAN;

in this latest case <AcT>, <tac> and <ci> are sent only if available.

 

NOTE 1: If the EPS MT in GERAN/UTRAN/E-UTRAN also supports circuit mode services and/or GPRS services,

the +CREG command and +CREG: result codes and/or the +CGREG command and +CGREG:

result codes apply to the registration status and location information for those services.

The read command returns the status of result code presentation and an integer <stat>

which shows whether the network has currently indicated the registration of the MT.

Location information elements <tac>,<ci> and <AcT>, if available, are returned only when <n>=2 and MT is registered in the network.

2. For automatic time and time zone update is enabled (+CTZU=1):

If time zone is only received from network and it isn’t equal to local time zone (AT+CCLK),

time zone is updated automatically, and real time clock is updated based on local time

and the difference between time zone from network and local time zone (Local time zone must be valid).

If Universal Time and time zone are received from network,

both time zone and real time clock is updated automatically, and real time clock is

based on Universal Time and time zone from network.

<tz> Local time zone received from network, it’s an integer, and the format is “±tz”.
<dst>

Network daylight saving time, and if it is received from network,

it indicates the value that has been used to adjust the local time zone.

The values as following:

0    No adjustment for Daylight Saving Time.

1    +1 hour adjustment for Daylight Saving Time.

2     +2 hours adjustment for Daylight Saving Time.

<time>

Universal time received from network, and the format is “yyyy/MM/dd,hh:mm:ss”,

where characters indicate year (two last digits), month, day, hour, minutes and seconds.

NOTE:  Here in,<time> is Universal Time or NITZ time.
