1.13.13
Control Plane Aiding / Location Services (LCS)
Not supported by SARA-G3 series modules.
Not supported by the “00” product version of SARA-U2 module.
With the Assisted GPS feature, a location server provides the module with the GPS system information that
otherwise must be downloaded from satellites. The feature allows faster position fixes, increases sensitivity and
reduces module power consumption. The feature is invoked by the module through LCS Supplementary Services
or by the Network during emergency calls.
The assisted GPS Location Services feature is based on the Radio Resources Location Protocol (RRLP), according
to
3GPP TS 44.031
[22], and Radio Resource Control (RRC) according to
3GPP TS 25.331

1.13.14
Bearer Independent Protocol
Not supported by the “00” and “01” product versions of SARA- G3 series modules.
Not supported by the “00” product version of SARA-U2 module.
The Bearer Independent Protocol (BIP) is a mechanism by which a cellular module provides a SIM with access to
the data bearers supported by the network. With the BIP for Over-the-Air SIM provisioning, the data transfer to
and from the SIM uses either an already active PDP context or a new PDP context established with the APN
provided by the SIM card.

u-blox AT Commands Manual
1.13.15
Multi-Level Precedence and Pre-emption Service
Not supported by SARA- G3 series modules.
Not supported by the “00” product version of SARA-U2 module.
The Multi-Level Precedence and Pre-emption Service (eMLPP) permits to handle the call priority. The maximum
priority associated to a user is set in the SIM: within this threshold, the user can assign different priorities to the
calls. This results in a differentiated treatment of the calls by the network in the event of abnormal events such
as handovers to congested cells.

u-blox AT Commands Manual
1.13.16
Network Friendly Mode
Not supported by the “00” and “01” product versions of SARA- G3 series modules.
Not supported by the “00” product version of SARA-U2 module.
The Network Friendly Mode (NFM) feature provides a more efficient access to the network since it regulates the
number of network accesses per service type over a configurable amount of time, avoiding scenarios in which
the cellular module continuously retries a registration or a PDP context activation procedure until it is successful.
For appropriate network rejection errors, a back-off timer can be started: when the timer is running or the
number of allowed accesses is reached, further attempts are denied and an URC may be enabled to indicate the
time remaining before a further attempt can be served. The back-off timer controls the temporal spread of
successive attempts to register to CS or PS services, to activate a PDP context and to send SMS messages.
