the core network practitioners face different business processes

signaling agreement

their own skill reserves are also very different. With the 5 G network cloud

SBA service network architecture has been provided

so the core network professional integration will come true in future

whether it is equipment manufacturers

or operators of the core network practitioners such as the current sub-professional transformation to cope with

obviously difficult to be competent. This article mainly focus on the SBA service architecture explaining

the core network functional level of the core network integration analysis

the core network internal processing logic level integration analysis

from above aspects to analyze the SBA architecture under the core network professional integration of unified feasibility

which is the reference for the core network element functional unit capacity design

and also practitioners’ ability improvement and transformation.
