MME + P-GW + S-GW implementation of 3GPP standard.

Non-UE associated control plane goes directly from S1AP to MME application layer.

Current development:
|
|
|
|
- NAS layer: under development
|
|
- S1AP layer: compliant with 3GPP TS36.413-8a0 and TS36.413-980 (under development)
|
|
- 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) link: http://lionet.info/soft/asn1c-0.9.21.tar.gz
|
|
- freediameter 1.1.5 patched (apply patch in DIAMETER/) with gnutls 3.1.0
|
|

|

|
|
Compilations steps for use with oaisim 4G emulation environment:
|
|
./autogen.sh
|
|
mkdir objs && cd objs
|
|
../configure [options]
|
|
make
|
|
|
|
Compilations steps for oaisim_mme use alone:
|
|
./autogen.sh
|
|
./configure [options]
|
|
make
|
|
|
|
Current options supported for configure:
|
|
--disable-r9: disable R9 S1AP messages (R9 enabled by default)
|
|
code build switch: UPDATE_RELEASE_9
|
|
|
|
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
|
|
|
|
Bugs:
|
|
report any bug to openair_admin@eurecom.fr
|
|
|
|
MME SCTP port for S1AP messages is 36412

-------- 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 Makefile and Makefile.in, they are re-generated by
|
|
autoconf/automake.
