2.2 IMS entity and Function Description
This section describes IMS entities and key functions. These entities can be roughly divided into six categories: session control and routing entity family (cscfs), Database entity (HSS, SLF), and interconnected entity(Bgcf, mgcf, im-MGW, SGW), service-related entities (application server, mrfc, mrfp), s

As the mobile market becomes more competitive and ARPU declines, it urges equipment providers and telecom operators to provide and build next-generation mobile core networks that are more cost-effective, powerful, and convenient for future evolution. This next-generation mobile core network should achieve cost optimization, taking both CAPEX and OPEX into account. It is conducive to rapid business introduction, including network architecture and equipment transformation. It meets the requirement

Summary:
Core platform of 3GPP, http://www.3gpp.org/ftp/Specs/html-info/23228.htm
First released by 3GPP Release 5, in order to enhance packet-switched domain (UMTS) in supporting IP multimedia services.
Providing back compatibility to circuit-switched domains and functionality to other IMs domains.
Nowadays, IMS provides access to Internet services (e.g. email, VoIP, video, etc) overdifferent network
with an HMAC. HMAC is formed in this way: first, a data structure is established, which includes Alice's temporary value, Bob's temporary value, their identification, and shared secret key KAB; then hash the data structure and the hash result is HMAC.
When Alice received message 2, she now had the identity of Ra, Rb, both sides, and secret key KAB, so she could also calculate HMAC. if the calculated HMAC is the same as the HMAC in the message, she knows that she is talking to Bob.

I believe everyone is in touch with the SIP protocol. In the previous article, we also discussed the content of the SIP protocol. If you are not clear about it, you can review it a little. We know that the SIP protocol has a huge development potential in the network communication field. Here we will explain the content of the IMS and SIP protocols.
