In this paper we consider the evolution of a GSM-based indoor corporate network, where base transceiver stations (BTS) are IP end-points of the local area network (LAN).Multiplexing capabilities of Real Time Protocol (RTP) payloads are exploited in order to efficiently transport TRAU (Transcoding and Rate Adaptation Unit) frames between each BTS and the BSC (Base Station Controller)/ Access Node. In this context two RTP connections are used to transmit downlink TRAU frames to both current BTS and candidate BTS during handover execution, thus allowing to prevent typical loss of voice frames during this phase. This would contribute to improve the Quality of Service (QoS) for voice communications in the selected environment. Signaling issues and assignments of resources to individual connections within a single RTPAJDPDP connection in the described environment are also addressed. The proposed architecture also offers advantages for implementing Tandem Free Operation (TFO) in a local environment.
