Go to your own blog early, and save it for future blocking. 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

Although smart switches can process different types of traffic, they can also limit the broadcast traffic. But objectively speaking, with the current technology, smart switches cannot meet the needs of all users. 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

Smart switches are worth learning a lot. Here we mainly introduce the functions and applications of smart switches. As smart switches are becoming more and more worth learning, here we will mainly introduce the process of moving towards the edge of the network, and we have been faced with various questions from users: whether smart switches are used to make small use of edges, can all network congestion be solved, VoIP is supported, and firewall can b

Whether the smart switch is used for minor edge issues, whether it can completely solve network congestion problems, whether it supports VoIP, and whether it can replace the firewall ...... When the smart switch is gradually moving towards the edge of the network, it is always faced with various questions from users. In fact, smart switches can and cannot.

When the intelligent switch gradually to the edge of the network process, has been facing the user's various questions: whether the smart switch for the edge is overqualified, whether it can solve the network congestion problem, whether to support VoIP, can replace the firewall. In fact, the intelligent switch can be, there is no. The concept of intelligent switch has been given a lot of mythological colors, as if all network problems will be solved.

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
