A接口IP化改造的规模部署，使2G/3G网络电路域具备了IP化语音实现TrFO的条件。本文针对A接口IP化后实现TrFO中遇到的问题，分析了统一编解码策略（GCP）部署的必要性。同时结合GCP测试中出现的问题，重点研究基于A接口IP化的GCP部署中面临的一些问题，并给出了相应的解决方案。

With the scale deployment of A interface transformed from TDM to IP, the transcoder free operation (TrFO) in circuit domain of 2G/3G network can make possible. By discussing problems in the TrFO, this paper analyzes the necessity of implementing GCP after AoIP. Combined with the GCP test in labs, this paper researches the dififculties of GCP during the implementation and proposes solutions against these problems.
