String type;half a byte in a 4-bit format.

The edrx value Refers to bit 4 to 1 of octet 3 of the Extended DRX parameters information

element (see sub-clause 10.5.5.32 of 3GPP TS 24.008).

For the coding and the value range, see the Extended DRX parameters information element in

3GPP TS 24.008 Table 10.5.5.32/3GPP TS 24.008.

<Paging_time_window>

String type;half a byte in a 4-bit format.

The paging time window refers to bit 8 to 5 octet 3of the Extended DRX.

Parameters information element (see sub-clause 10.5.5.32 of 3GPP TS 24.008).
