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 are applied to the registration status and location information for those
services.
2.
3GPP TS 24.008
and
3GPP TS 24.301
specify the condition when the MS is considered as attached
for emergency bearer services.
3.
3GPP TS 44.060
specifies the System Information messages which give the information about
whether the serving cell supports EGPRS.
4.
3GPP TS 25.331
specifies the System Information blocks which give the information about whether
the serving cell supports HSDPA or HSUPA.
Example
AT+CEREG=1
//Enable network registration URC.
OK
AT+CEREG?
+CEREG: 1
OK
AT+CEREG=?
+CEREG:(0,1,2)
OK
Neul Hi2110 Implementation
Only CEREG <n> values of 0, 1 and 2 are supported.
<stat> return values 0-5 are supported.
allocated to the UE in E-UTRAN. The Active Time value is coded as one byte (octet 3)
of the GPRS Timer 2
information element coded as bit format (e.g. “00100100” equals
4 minutes). For the coding and the value range, please refer to the
GPRS Timer 2 IE
in 3GPP TS 24.008 Table 10.5.163/3Gpp TS 24.008
,
3GPP TS 23.682
and
3GPP TS
23.401.
<Periodic-TAU>
String type; one byte in an 8 bit format. Indicates the extended periodic TAU value
(T3412) allocated to the UE in E-UTRAN. The extended periodic TAU value is coded
as one byte (octet 3) of the GPRS Timer 3 information element coded as bit format
(e.g. “01000111” equals 70 hours). For the coding and the value range, please refer to
the
GPRS Timers 3 IE in 3GPP TS 24.008 Table 10.5.163a/3GPP TS 24.008
,
3GPP
