This directory contains the necessary scripts and Makefiles to generate all the LTE configuration data structures based on the ASN.1 RRC
|
|
source code from the 36.331 RRC specifications. These structures are used by MAC and PHY for configuration purposes.
|
|
|
|
It contains the following files
|
|
|
|
README.txt : This file
|
|
Makefile.inc : Makefile to be included by OpenAir compilation scripts for LTE Data structures
|
|
asn1c : Directory to place asn1c package
|
|
asn1c/ASN1_files/36331-860.txt : Text file containing 36.331-860 specifications used to generate ASN1 source
|
|
asn1c/ASN1_files/extract_asn1_from_spec.pl : Pearl script to extract ASN.1 source from 36311-860.txt
|
|
asn1c/ASN1_files/EUTRA-RRC-Definitions.asn : First ASN.1 source (generated from above .txt file)
|
|
asn1c/ASN1_files/EUTRA-InterNodeDefinitions.asn .asn : Second ASN.1 source (generated from above .txt file)
|
|
asn1c/ASN1_files/EUTRA-UE-Variables.asn : Third ASN.1 source (generated from above .txt file)

Instructions to build data structures from ASN1 sources
|
|
|
|
The three files have already been built using the extract_asn1_from_spec.pl Pearl script. This should be used again if a newer version
|
|
of the RRC spec is used to synthesize the data structures and encoding/decoding routines. To do this:
|
|
1. use Microsoft WORD to generate a text version of the 3GPP 36.331 document
|
|
2. run the script on the text file to generate the three files.
|
|
|
|
Now download the asn1c utility (version 0.9.22) from
|
|
|
|
http://lionet.info/asn1c/blog/
|
|
|
|
or via svn from sourceforge (version 0.9.22)
|
|
|
|
For version 0.9.2:
|
|
svn co https://asn1c.svn.sourceforge.net/svnroot/asn1c/trunk asn1c
|
|
For the latest version:
|
|
svn co https://github.com/vlm/asn1c/trunk asn1c
|
|
|
|
and put it in the asn1c directory (you should have a second asn1c directory now). Compile it and install it locally
|
|
(or make sure your $PATH can find the asn1c executable) according to the instructions given (see INSTALL file)
|
|
by the author. We have validated that 0.9.22 works on Linux and Cygwin. To generate the data structures do the following from the
|
|
current directory
|
|
|
|
asn1c -gen-PER -fcompound-names -fnative-types -fskeletons-copy ./asn1c/ASN1_files/EUTRA-RRC-Definitions.asn
|
|
|
|
Note this only uses one of the three files from 36.331 (the core of the RRC). After this step you should have many .c and .h files
|
|
and one new Makefile, the latter of which is not used.
|
|
|
|
If you want to compile the ASN1 sources as a kernel module you need to apply the patch asn1_patch
|
|
|
|
patch -p1 < asn1_patch
