这几年陆陆续续有一些研究类的朋友问我IMS该怎么办?其实不管怎么办,研究院的一般是花钱办,采购那几个企业的产品而已,大多运营商是不会使用不花钱的系统的,但是作为研究院的,不得不研究,前段时间有人看到OpenSIPS3.6支持IMS的局部,然后问我可不可以选择,我说没必啊,还是得看Kamailio。毕竟Kamailio在IMS体系中一直持续输出了十多年的努力。以下就是列出相关信的信息
OpenSIPS的相关模块 2024.4月开始提交
介绍
OpenSIPS 3.6 philosophy Bits and pieces of the IMS (IP Multimedia Subsystem) topic were part of the previous OpenSIPS release, but this 3.6 fully focused on the IMS part. Considering the traction and need of IMS solutions, the implementation of a consistent and large IMS support in OpenSIPS was a mandatory step in order to answer to the needs of the industry.
The IMS topic is a large one, transcending the SIP protocol and the scope of OpenSIPS. So, the OpenSIPS 3.6 worked out the parts of the IMS ecosystem which are based or related to SIP, of course.
IMS
The IMS topic is a very large and complex one. And the goal here was to design and implement an IMS support that is truly able to provide solutions for the industry. So, a quite extensive stage of exploring, understanding and designing on the IMS ecosystem was required in a first stage. This work was undertaken by the IMS OpenSIPS Working Group (IMS OWG), a gathering of people with common inters in IMS, working together to draft, design and implement the IMS support in OpenSIPS. The IMS Working group compiled a Scope Of Work, which helped in laying down the actual requirements. The group decision was to tackle, at this first stage, the CSCF components, together with its interfaces. As results, this translated in work across several module along with the addition of new specialized modules.
AKA digest authentication Present in the S-CSCF, the AKA authentication mechanism (RFC 3310) is implemented by the new AUTH_AKA module. Its complex interaction through the Cx/Dx Diameter interface is provided by the new AKA_AV_DIAMETER module, responsible for fetching and managing the authentication vectors required by AKA.
IPSEC support Present in the P-CSCF
AAA support Presence support SQL operations Launch Darkly Message Queue Miscellaneous but important 简单来说,OpenSIPS 3.6 制定了 IMS 生态系统中基于 SIP 或与 SIP 相关的部分
PROTO_IPSEC - implements IMS IPSec protocol according to TS 33.203 specs, beta
Kamailio的相关模块2012年左右已开始提交

也就是说Kamailio的IMS在2011年有规划和起步,换个角度,以IMS直接命名的模块
