Parameter
1. RAI (Release Assistance Indication) is introduced in
3GPP
Release 14
and it is primarily a MAC layer
feature.
2. The RAI feature is only applicable to NB-IoT RAT. This feature allows to track predictable nature of
data traffic and requests for connection release when there is no additional data to be sent. It is
essentially a ‘fast dormancy’ feature to save battery power of the UE.
2.3.10. AT+QISWTMD Switch Data Access Mode
This command switches the data access mode among buffer access mode, direct push mode and
transparent transmission mode. When starting a socket service, the data access mode can be specified
via the
<access_mode>
of
AT+QIOPEN
. After a socket has been opened, the data access mode can be
changed with
AT+QISWTMD
.
OK
Write Command
AT+QISENDEX=<connectID>,<
hex_string>[,<RAI_info>]
Response
If the hex string is sent successfully:
SEND OK
If the sending buffer is full:
SEND FAIL
If the connection does not exist:
ERROR
Maximum Response Time
120 s, determined by network.
