In this case, the mobile operator should take into account both the long-term strategy and the short-term goal, and work out a plan for the evolution of the mobile network to the NGN network based on the IMS architecture based on the current product technical

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

Analysis of key technical issues of IMS-based network convergence Font Size:SmallMediumLarge|PrintRelease: Author: webmaster Source:Network reposted: 78 timesThe emergence of Softswitch technology has led to the adoption of Softswitch technology for the integration of core control layers. However, due to the large differences in fixed and mobile Softswitch functions and protocols, Softswitch has become the focus of control layer integration. The possi

In the development trend of network convergence, 3GPP, ETSI and ITU-T are both studying the IMS-based network convergence Scheme, which aims to make IMs a general platform based on SIP session, it also supports various fixed and mobile access methods to achieve convergence between fixed and mobile networks. For example, the integration of mobile network, PHS and fixed network resources to provide voice data

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

I believe that you have mastered the basics of IMS and SIP protocols and some precautions. These contents are also described in two articles, "briefly describing the SIP protocol in IMS" and "Problems Existing in IMS and SIP. Next we will explain the SIP Protocol extensions in IMS. 1. SIP Compression The session creati

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. Alice also

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. 1. Brief Introduction to IMS and SIP protocols The IP Multi

I. Overview Review the video surveillance market, the monitoring platform system used by the signaling control protocol is not unified, resulting in the interconnection of the technical threshold. This is a bit similar to the 80 's China's switch market eight system of the situation. These reasons hinder the network era of large-scale carrier-level video surveillance, remote access, centralized management needs. The industry has explored two ways to solve the problem: From the monitoring industr
