Set command

The set command reads dynamic Extended Discontinuous Reception (eDRX) parameters.

Syntax:

+CEDRXRDP

Response syntax:

+CEDRXRDP: <AcT-type>[,<Requested_eDRX_value>[,<NW-provided_eDRX_value>[,<Paging_time_window>]]]

The set command parameters and their defined values are the following:

<ActT-type>
0 – Current cell not using eDRX
4 – Evolved Terrestrial Radio Access Network (E-UTRAN) (WB-S1 mode)
5 – E-UTRAN (NB-S1 mode)
<Requestd_eDRX_value>
String. Half a byte in 4-bit format. The eDRX value refers to bit 4 to 1 of octet 3 of the Extended DRX parameters information element (see 3GPP TS 24.008, subclause 10.5.5.32).
<NW-Provided_eDRX_value>
String. Half a byte in 4-bit format. The eDRX value refers to bit 4 to 1 of octet 3 of the Extended DRX parameters information element (see 3GPP TS 24.008, subclause 10.5.5.32).

The following command example reads eDRX parameters:

AT+CEDRXRDP
+CEDRXRDP: 4,"0011","0010","1001"
OK
1 The value is applicable only in WB-S1 mode. If received in NB-S1 mode, it is interpreted as if the Extended DRX parameters IE were not included in the message by this version of the protocol.
2 The value is applicable only in WB-S1 mode. If received in NB-S1 mode, it is interpreted as 0010 by this version of the protocol.
3 The value is applicable only in NB-S1 mode. If received in WB-S1 mode, it is interpreted as 1101 by this version of the protocol.
