Baseband Processing Unit (BBU) Core of Mobile Communication Base Stations

The BBU core network integration incorporates the Baseband Unit to the core network of a communication system. It is the action of facilitating communication channels without hindrance for the flow of information and control signals. BBUs are required to interface with different components of the core networks such as mobile switching centers and packet data gateways. In 4G networks, integration entails particular control protocol settings of S1 - MME and S1 - U while for 5G Core Networks, the interfaces utilized are NG-xx. There needs to be proper alignment and synchronization between the BBU and core network. Any configuration or interoperability issue could lead to service disruptions, call failures, and throttled speeds among users.
