16  *
17  * <HR>
18  *
19  * The Low Power Technologies (LPT) APIs are used to control the low power features of the modem.
20  *
21  * @section le_lpt_binding IPC interfaces binding
22  *
23  * All the functions of this API are provided by the @b modemService service.
24  *
25  * Here's a code sample binding to modem services:
26  * @verbatim
27  bindings:
28  {
29  clientExe.clientComponent.le_lpt -> modemService.le_lpt
30  }
31  @endverbatim
32  *
33  * @section le_lpt_eDRX eDRX
34  *
35  * The extended idle-mode discontinuous reception (eDRX) is a mechanism that reduces power
36  * consumption by extending the sleeping cycle in idle mode. It allows the device to turn part of
37  * its circuitry off during the extended DRX period to save power. During the extended DRX period,
38  * the device is not listening for paging or downlink control channels, so the network should not
39  * try to contact the device.
40  *
41  * @warning Enabling eDRX introduces a longer latency in reaching the device and should therefore
42  * not be used by systems that cannot handle it, e.g. systems supporting mobile-terminated voice.
43  *
44  * The use of eDRX for a given radio access technology (@ref le_lpt_EDrxRat_t) can be enabled and
45  * disabled with le_lpt_SetEDrxState().
46  *
47  * @snippet "apps/test/modemServices/lpt/lptIntegrationTest/lptTest/lptTest.c" Set state
48  *
49  * The eDRX feature is controlled by two parameters, which are defined in the standard 3GPP
50  * TS 24.008 Release 13 Section 10.5.5.32: the eDRX value, defining the eDRX cycle length, and
51  * the Paging Time Window. These parameters are negotiated between the device and the network during
52  * an attach or routing area updating procedure.
53  *
54  * The requested eDRX value can be set with le_lpt_SetRequestedEDrxValue() and retrieved with
55  * le_lpt_GetRequestedEDrxValue().
56  *
57  * @snippet "apps/test/modemServices/lpt/lptIntegrationTest/lptTest/lptTest.c" eDRX value
58  *
59  * The eDRX value provided by the network can be retrieved with
60  * le_lpt_GetNetworkProvidedEDrxValue().
61  *
62  * @snippet "apps/test/modemServices/lpt/lptIntegrationTest/lptTest/lptTest.c" NP eDRX value
63  *
64  * The requested Paging Time Window cannot be set, but the network-provided value can be retrieved
65  * with le_lpt_GetNetworkProvidedPagingTimeWindow().
66  *
67  * @snippet "apps/test/modemServices/lpt/lptIntegrationTest/lptTest/lptTest.c" NP PTW
68  *
69  * A handler can also be registered with le_lpt_AddEDrxParamsChangeHandler() in order to be notified
70  * of the changes in the network-provided eDRX parameters.
71  *
72  * @snippet "apps/test/modemServices/lpt/lptIntegrationTest/lptTest/lptTest.c" eDRX handler
73  * @snippet "apps/test/modemServices/lpt/lptIntegrationTest/lptTest/lptTest.c" Add eDRX handler
74  *
75  * The handler can be removed with le_lpt_RemoveEDrxParamsChangeHandler().
