Allocating Abis interface transmission channels in packet cellular radio network

摘要

The invention relates to a network part, comprising packet control means (180A/180B) for communicating through an Abis interface and means (118, 124) for allocating fixedly on the Abis interface a certain number of transmission channels to base-station-specific operations and maintenance signalling and to transceiver-specific telecommunication signaling. The packet control means (180A/180B), using in-band signalling, are adapted to dynamically allocate on the Abis interface a necessary number of transmission channels to packet data transfer, the amount of packet data varying according to the modulation and coding scheme used on a Um interface.
