IMS 支持接口

MSC接口，信令：ISUP over IP和SIP, 用户面： rtp协议

PCRF接口,Rx接口

HSS接口, Cx接口

Kamailio 和 openIMS,  Kamailio本身就是一个SIP AS(Application server), 而且可以通过加载模块的方式在支持不同的接口，而且目前已经支持Rx Cx接口

撒花。继续加载模块。

nothing is unreachable.

notes：

1.  mkdir -p /usr/local/src/kamailio-devel
  cd /usr/local/src/kamailio-devel

 make cfg

  nano -w modules.lst

　include_modules= db_mysql　

　make include_modules="db_mysql dialplan" cfg //to enable modules which are not compiled by default, 

2.

make all

make install

The binaries and executable scripts were installed in:

  /usr/local/sbin

• kamailio - Kamailio SIP server
• kamdbctl - script to create and manage the Databases
• kamctl - script to manage and control Kamailio SIP server
• sercmd - CLI - command line tool to interface with Kamailio SIP server

  PATH=$PATH:/usr/local/sbin
  export PATH

Kamailio (OpenSER) modules are installed in:

  /usr/local/lib/kamailio/modules/

The documentation and readme files are installed in:

  /usr/local/share/doc/kamailio/

The man pages are installed in:

  /usr/local/share/man/man5/
  /usr/local/share/man/man8/

The configuration file was installed in:

  /usr/local/etc/kamailio/kamailio.cfg

3. database

 试试：service mysqld start 

mysql -u root

mysqladmin -u root password vankom

To create the MySQL database, you have to use the database setup script. First edit kamctlrc file to set the database server type:

  nano -w /usr/local/etc/kamailio/kamctlrc

Locate DBENGINE variable and set it to MYSQL:

DBENGINE=MYSQL

You can change other values in kamctlrc file, at least it is recommended to change the default passwords for the users to be created to connect to database.

Once you are done updating kamctlrc file, run the script to create the database used by Kamailio:

  /usr/local/sbin/kamdbctl create

You can call this script without any parameter to get some help for the usage. You will be asked for the domain name Kamailio is going to serve (e.g., mysipserver.com) and the password of the 'root' MySQL user. The script will create a database named 'kamailio' containing the tables required by Kamailio. You can change the default settings in the kamctlrc file mentioned above.

The script will add two users in MySQL:

- kamailio - (with default password 'kamailiorw') - user which has full access rights to 'kamailio' database

- kamailioro - (with default password 'kamailioro') - user which has read-only access rights to 'kamailio' database

Do change the passwords for these two users to something different that the default values that come with sources.

4. Edit configuration file

To fit your requirements for the VoIP platform, you have to edit the configuration file.

  /usr/local/etc/kamailio/kamailio.cfg

Follow the instruction in the comments to enable usage of MySQL. Basically you have to add several lines at the top of config file, like:

#!define WITH_MYSQL
#!define WITH_AUTH
#!define WITH_USRLOCDB

If you changed the password for the 'kamailio' user of MySQL, you have to update the value for 'db_url' parameters.

You can browse kamailio.cfg online on GIT repository.

5. The init.d script

The init.d script can be used to start/stop the Kamailio server in a nicer way. A sample of init.d script for Kamailio is provided at:

/usr/local/src/kamailio-devel/kamailio/pkg/kamailio/deb/debian/kamailio.init

Just copy the init file into the /etc/init.d/kamailio. Then change the permisions:

  chmod 755 /etc/init.d/kamailio 

then edit the file updating the $DAEMON and $CFGFILE values:

  DAEMON=/usr/local/sbin/kamailio
  CFGFILE=/usr/local/etc/kamailio/kamailio.cfg

You need also setup a configuration file in the /etc/default/ directory. This file can be found at:

  /usr/local/src/kamailio-devel/pkg/kamailio/debian/kamailio.default

You need to rename the file to 'kamailio' after you've copied it. Then edit this file and set RUN_KAMAILIO=yes. Edit the other options at your convenience.

Create the directory for pid file:

mkdir -p /var/run/kamailio

Default setting is to run Kamailio as user “kamailio” and group “kamailio”. For that you need to create the user:

adduser --quiet --system --group --disabled-password \
        --shell /bin/false --gecos "Kamailio" \
        --home /var/run/kamailio kamailio

# set ownership to /var/run/kamailio
chown kamailio:kamailio /var/run/kamailio

Then you can start/stop Kamailio using the following commands:

  /etc/init.d/kamailio start
  /etc/init.d/kamailio stop

6. Ready to rock

Now everything is in place. You can start the VoIP service, creating new accounts and setting the phones.

A new account can be added using 'kamctl' tool via 'kamctl add <username> <password> <email>'. (or try without the email)

kamctl add test testpasswd test@mysipserver.com

If you are asked for SIP_DOMAIN environment variable do one of the following option.

  1.
  export SIP_DOMAIN=mysipserver.com

  2.
  edit '/root/.kamctlrc' and add:
  SIP_DOMAIN=mysipserver.com

7. Maintenance

The maintenance process is very simple right now. You have to be user 'root' and execute following commands:

  cd /usr/local/src/kamailio-devel/kamailio
  git pull origin
  make all
  make install
  /etc/init.d/kamailio restart

Now you have the latest Kamailio devel running on your system.

8. Time for maintenance service

Notification about GIT commits are sent to the mailing list: sr-dev@lists.sip-router.org. Each commit notification contains the reference to the branch where the commit has been done. If the commit message contains the lines:

Module: sip-router
Branch: master

then an update has been made to Kamailio devel version and it will be available to the public GIT in no time.

4. Functions

4.1. Rx_AAR_Register(domain)
4.2. Rx_AAR(domain)

4.1. Rx_AAR_Register(domain)

Perform a AAR on Diameter RX interface to subscribe to signalling
status. This purpose of this is tell a Diameter server (typically a
PCRF) to inform the requesting Diameter client on changes to the status
of signalling bearer for the same framed IP address. For more details
see 3GGP TS 29.214.

Meaning of the parameters is as follows:
* domain that usrloc_pcscf uses to store user information.

This function can be used from REQUEST_ROUTE.

p.s. this is executed asynchronously. See example on how to retrieve
return value

Example 1.7. Rx_AAR_Register
...
Rx_AAR_Register("location");

switch ($avp(s:aar_return_code)) {
case 1:
xlog("L_DBG", "Diameter: AAR success on subscription to signalling\n
");
break;
default:
xlog("L_ERR", "Diameter: AAR failed on subscription to signalling\n"
);
t_reply("403", "Can't register to QoS for signalling");
exit;
}

...

4.2. Rx_AAR(domain)

Perform a AAR on Diameter RX interface to request resource
authorisation from a Diameter server (typically a PCRF). For more
details see 3GGP TS 29.214.

Meaning of the parameters is as follows:
* domain that usrloc_pcscf uses to store user information.

This function can be used from REQUEST_ROUTE or ONREPLY_ROUTE.

p.s. this is executed asynchronously. See example on how to retrieve
return value

Example 1.8. Rx_AAR
...
Rx_AAR("location");

switch ($avp(s:aar_return_code)) {
case 1:
xlog("L_DBG", "Diameter: AAR success\n");
break;
default:
xlog("L_ERR", "Diameter: AAR failed\n");
t_reply("403", "QoS not authorized");
exit;
}

...
