The purpose of the present document is to study:
The feasibility of out-of-band transcoder control in UMTS/IMT-2000 networks.
The impact of out-of-band transcoder control on the UMTS/IMT-2000 specifications.
The present document introduces one enhanced in-band transcoder control procedure and four out-of-band transcoder control procedures that might be adaptable for transcoder control in UMTS/IMT-2000 networks. Then compare each procedure from various point of views to seek the most feasible procedure.
