The document discusses TELUS's implementation of AWS serverless technology for building a 3GPP core and BSS. It highlights the complexities faced by telecom companies and presents solutions to simplify subscription and connectivity processes while reducing costs. The document also covers the importance of adopting a serverless architecture for modern telecom infrastructures.

10. 문제에 집중
모든 것이 다시 리엔지니어링 될 수 있는,
해결할 문제가 있는 집중해야 할 영역 :
표준을 따르는 것은 불필요한 오버헤드
장치 모뎀, eUICC나 RAN 등
통신 표준 규격을 따라야 하는 외부 요소
통신사 기능이 배치되기 좋은,
통신사가 고려하지 않아도 되는 인프라 영역
