4G QOS Vs 5G network Slicing

Mobile Broadband Network has always succeeded to provide services to end-users via partitioning the network through Bearers & APNs. Till now all Telecom Network build keeping in mind to serve Human and as industry wrap around with newer application on TOP of Telco pipe. Telco needs to upgrade according to new requirements which lead to evaluation from one Network serving all kinds of services to Dedicated Core Network Instances serving more targeted segments

With the introduction of 5G, a Network Slicing framework that advocates 4 standard slices to be used for global Interoperability (eMBB, uRLLC, MIoT, & V2X) and allowing more space for dynamic slices addressing different Marketing Segments. These slices are globally identified by Slice/Service Type (SST) which maps to the expected network behavior in terms of services and characteristics.

The key differentiator of the network slicing approach is that it provides an end-to-end virtual network for a given tenant which is not possible in the case of 4G. Network slicing is very different from QoS because it will enable end-to-end virtual networks encompassing compute, storage and networking functions.
