| Abstract: | 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 difficulties of GCP during the implementation and proposes solutions against these problems. |
