NSA+SA mode is the first step in the development of 5G network, that is, choosing dependent networking mode. In this mode, the terminal can use NSA (non-independent networking) to connect to the 5G network, and then use the services provided by the 5G network in SA (independent networking) mode. This mode can reduce the cost of network deployment, because only one SA network license needs to be deployed to provide 5G services for all terminals.
NSA mode is the second step in the development of 5G network, that is, choose independent networking mode. In this mode, the terminal needs to purchase the SA network license separately, and can connect to the 5G network after purchase. Although this method can provide faster 5G network speed, it needs more investment and deployment costs. Therefore, compared with NSA mode, NSA+SA mode has better flexibility and economy, and can better adapt to different network deployment scenarios.
Advantages and disadvantages of NSA+SA model
Advantages of 1 and NSA+SA mode
Start the 5G network faster.
Reduce the cost of operators.
Improve the coverage of 5G networks.
2. Disadvantages of NSA+SA model
Because NSA+SA mode needs to use both 4G and 5G networks, it will increase the complexity of the network.
In NSA+SA mode, devices may not be able to make full use of the new functions of the 5G network.
In NSA+SA mode, devices may be affected by network switching, resulting in unstable network connection.
NSA+SA mode is a deployment mode of 5G networks, which can help operators to launch 5G networks faster, reduce costs and improve coverage. However, NSA+SA mode also has some shortcomings, such as the increase of network complexity, the inability of devices to make full use of the new functions of 5G network, and the unstable network connection. Therefore, operators should choose the deployment mode according to their own needs and actual conditions.
