Abstract:
The functionality of the IP Multimedia Subsystem (IMS) is designed to operate on a variety of wireless access
technologies and throughout the access network coverage, such as RTC, 3G, 4G and even 5G networks. In this article, we have
set up an IMS registration procedure for the different networks. In addition, the SIP-based call setup mechanism based on SIP.
Two processes have been taken into account, in the registration process and the re-registration process, which is a
complementary procedure for the registration process. Our results show that the proposed framework has achieved the goal
of registering user equipment in the IMS for different access networks. In addition, the proposed IMS module implanted has
succeeded in playing the expected role.
