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.
- A configuration value that the network provides for the eDRX period. The value in this
parameter does not necessarily indicate that eDRX is in use by the current cell to which
the User Equipment (UE) is registered. The use of eDRX can be dynamically
monitored with the unsolicited notification +CEDRXP and its
<ActT-type> parameter.
- 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).

octet 3 of the Extended DRX parameters information element (see 3GPP TS 24.008,
subclause 10.5.5.32).
