SDH network having dynamic allocation of transmission capacity
First Claim
1. A microcellular radio network, comprising:
- a plurality of base transceiver stations and higher-level network elements, and a transmission network having node means to which the base transceiver stations and higher-level network elements are connected for dynamic establishment of digital transmission links between the network elements and the base transceiver stations;
said transmission network being an SDH network including control means for dynamic allocation of transmission capacity of the transmission network to said base transceiver stations or higher-level network elements according to their traffic load, determined on the basis of the number of transmission channels in use and those not in use, or on the basis of load information obtained from the network management of the radio network;
said base transceiver stations or higher-level network elements being arranged to transmit a predetermined idle signal on the transmission channels allocated to them but not in use; and
said control means comprising means for recognizing the channels not in use on the basis of said idle signal, and means for defining the traffic load of each base transceiver station or higher-level network element on the basis of channels in use and those not in use.

Abstract
A microcellular radio network including a plurality of base transceiver stations and higher-level network elements, such as base station controllers and exchanges, and an SDH transmission network. The base transceiver stations and higher-level network elements are connected to nodes of the SDH network for dynamic establishment of digital transmission links. The network management of the SDH network is capable of dynamic allocation of transmission capacity of the transmission network to base transceiver stations or higher-level network elements according to their traffic load. The traffic load is determined on the basis of the number of transmission channels in use and those not in use, or on the basis of load information obtained from the network management of the radio network.
