Current development:
|
|
|
|
- NAS layer: under development
|
|
- S1AP layer: compliant with 3GPP TS36.413-8a0 and TS36.413-980 and TS35.413-a50
|
|
- SCTP layer: SEQ_PACKET socket types
|
|
|
|
For now the MME is able to register new eNBs on SCTP layer,
|
|
and handles S1 Setup request, Initial UE message, UplinkNASTransport on
|
|
S1AP layer.
|
|
|
|
The MME needs some libraries and tools:
|
|
- libsctp-dev (SCTP support)
|
|
- libpthread-dev
|
|
- asn1c utility (patched with Aligned PER support, see README in
|
|
S1AP/MESSAGES/ASN1)
|
|
- flex
|
|
- bison
|
|
To install the dependencies:
|
|
sudo apt-get install libsctp-dev libpthread-dev flex bison g++ gcc make -y
|
|
|
|
A script is present in S6A/freediameter to install required packages for
|
|
S6A interface over diameter. Run it as a sudoer.
|
|
|
|
install_openvswitch1.9.0.bash
|
|
cd S6A/freediameter/README
|
|
|
|
Compilations steps for use with oaisim 4G emulation environment:
|
|
./autogen.sh or autoreconf -i --force --install
|
|
mkdir objs && cd objs
|
|
../configure [options]
|
|
make
|
|
|
|
Compilations steps for oaisim_mme use alone:
|
|
./autogen.sh
|
|
./configure [options]
|
|
make
|
|
|
|
Current options supported for configure:
|
|
--enable-r8: disable R9 and R10 S1AP messages updates
|
|
--enable-r9: disable R10 updates
|
|
code build switch: UPDATE_RELEASE_9 and UPDATE_RELEASE_10
|
|
NOTE: Release 10 is enabled by default
|
|
--enable-standalone-epc: all-in-one package, MME, S-GW and P-GW are compiled in a single
|
|
executable and S11 interface is not used; messages are exchanged internally,
|
|
linking MME applicative layer to S+P-GW applicative layer
|
|
|
|
How to run EPC environnement ?
|
|
|
|
If you avec enabled the standalone option
|
|
the package is called oai_epc in the OAI_EPC directory.
|
|
|
|
If you have decided to use the S11 interface,
|
|
two executables should be run on different machines
|
|
|
|
* oai_sgw in OAI_SGW
|
|
* oaisim_mme in OAISIM_MME
|
|
|
|
For example to rum mme:
|
|
./OAISIM_MME/oaisim_mme [options]
|
|
Avalaible options:
|
|
-h: print help
|
|
-v: enable verbosity level [1-2]
|
|
-V: print current executable version and return
|
|
|
|
Before any commit:
|
|
make maintainer-clean
|
|
|
|
MME SCTP port for S1AP messages is 36412
|
|
SGW and eNB GTP-u port is 2152
|
|
SGW and MME GTP-c port is 2123

|
-------- Adding new files to build system --------
|
|
1) When adding a new file to compile, edit the Makefile.am of the corresponding
|
|
directory.
|
|
2) Execute ./autogen.sh
|
|
3) make
|
|
WARNING: do not edit directly Makefiles and Makefile.in, they are re-generated by
|
|
autoconf/automake.
