국내의 인터넷 전화(VoIP)는 서비스 출범 이후 매해 괄목할 만한 성장을 해 왔고, 지금도 지속적인 증가세를 유지하고 있다. 또한 인터넷 전화 시장이 성장한 만큼 모바일 인터넷 전화의 비율 또한 급팽창할 것으로 보인다. 이에 따라 모바일 인터넷 전화 서비스의 품질이 뛰어난 망 구축이 중요하다. 모바일 인터넷 전화 서비스는 이동성과 전송률이 뛰어난 망에 구축되어 사용되어야 할 것이다. 현재의 무선 인터넷 서비스망은 3G와 Wi-Fi, 모바일 와이맥스 망이 있다. 3G는 이동성은 뛰어나지만 전송률이 떨어지고, Wi-Fi는 전송률은 뛰어나지만 이동성이 떨어진다. 최근 양자의 장점을 취하여 뛰어난 이동성과 전송률을 가진 모바일 와이맥스 망의 구축이 확대되고 있다. 본 논문에서는 모바일 와이맥스망의 인터넷 전화 서비스에 대한 와이맥스 포럼의 최근 표준 동향을 살펴본다.
