GENERAL INFORMATION
|
||||||
|
===================
|
||||||
|
|
||||||
|
The 3GPP TS 36.331 version 14.2.1 Radio Resource Control (RRC) Unaligned PER decoder.
|
||||||
|
Invoking `make` will compile the ASN.1 specifications from the
|
||||||
|
../lte-rrc-14.2.1.asn1 file.
|
||||||
|
|
||||||
|
Currently only Makefile and binary sample in this directory.
|
||||||
|
|
||||||
|
OBTAINING THE LTE-RRC SPECIFICATION
|
||||||
|
===================================
|
||||||
|
|
||||||
|
To obtain this LTE-RRC ASN.1 specification or other version, you should go to
|
||||||
|
http://www.3gpp.org/ftp/Specs/html-info/36331.htm
|
||||||
|
and download any version of LTE-RRC specification you like.
|
||||||
|
|
||||||
|
A .ZIP file with a Microsoft Word .DOC files will download shortly.
|
||||||
|
|
||||||
|
You should extract the ASN.1 modules from that .DOC file.
|
||||||
|
Be careful not to copy any preambles, chapter titles and other non-ASN.1 text.
|
||||||
|
|
||||||
|
lte-rrc-dump USAGE
|
||||||
|
==================
|
||||||
|
|
||||||
|
The lte-rrc-dump utility may be used to dump the contents of a Unaligned PER-encoded
|
||||||
|
LTE-RRC protocol data unit. Since LTE-RRC specification contains multiple PDUs,
|
||||||
|
a PDU must be selected manually using -p <PDU> command line option:
|
||||||
|
|
||||||
|
./lte-rrc-dump -iper -p DL-DCCH-Message message.per
|
||||||
|
./lte-rrc-dump -iper -p PCCH-Message message.per
|
||||||
|
|
||||||
|
The list of recognized PDUs may be obtained using `-p list`.
|
||||||
|
|
||||||
|
The full list of recognized command line options may be obtained with
|
||||||
|
|
||||||
|
> ./lte-rrc-dump -h
