network connection mode (such as 3G, wireless access technology without band limit IEEE802.11, etc.). Now the integration technology that supports the terminal level is mainly Uma (unlicensed mobile access, license-free mobility). As early as January 2004, UMA technology was jointly initiated by a number of industry-leading operators and vendors to develop and promulgate a set of standards to extend mobile
Basic SIP Application
As one of the main VOIP communication protocols, the SIP protocol is simple, flexible, and open, and is gradually dominant in the VOIP communication field. The main methods used for SIP Communication include SIP terminals, proxy/targeted servers, location servers, and PSTN gateways. Currently, the latest standard of the SIP protocol is RFC3261. Major network equipment providers can cu
The demand for remote access is constantly increasing, and new technologies are also emerging. Even if one of eicon ums and VoIP servers is used, we will mainly introduce UMS (Unified Message Service ), this section describes the DIVA server card and Voice Gateway. As the world's leader in the remote access market, EICON is particularly outstanding in the ISDN field. It has a full range of isdn diva pc customer card/Server card, ISDN box MODEM and ISD

Single radio voice call continuity (srvcc) srvcc is an LTE functionality that allows a VoIP/IMS call in the LTE packet domain to be moved to a legacy voice domain (GSM/UMTS or CDMA 1X ). consider a case where a new LTE network operator wants to move voice services to VOIP over IMS in conjunction with the deployment of an LTE access network. in the

First, the relationship between FMC and IMS. IMS should be a long-term FMC architecture, fixed and mobile convergence, its development will inevitably go through several stages: first, we are currently in a stage, called the pre-IMS-FMC stage. Next we will develop to domain-level IMS and end-to-end IMS. Pre-IMS-FMC has appeared before IMS could run, such as UMA, IMA solutions, such as UK telecommun

Smart switches are quite common. So I have studied the basic functions and practical applications of smart switches. Here I will share with you, hoping they will be useful to you. When smart switches gradually move towards the edge of the network, they are always faced with various questions from users: whether smart switches are used to make minor use of the edge, whether they can completely solve network congestion problems, and whether they support VoIP
