Abstract:
A method for registering an overload situation in a telephone exchange system including a local exchange of a fixed telecommunication network, an access node for adapting signaling used by the fixed telecommunication network and signaling used by a wireless telecommunication network to each other, a concentrating interface for concentratingly connecting the access node to the local exchange by multiplexing links between the access node and the local exchange, the links comprising time slots for speech communication and time slots for signaling, a resource manager for monitoring which of the links are busy and which are free, the resource manager being part of the local exchange, and a statistical unit for recording statistical information about the links, the statistical unit being part of the local exchange,the method comprising the steps of: scanning the concentrating interface to find a free time slot for speech communication; detecting an overload situation of no free time slot available in the concentrating interface for speech communication by using the resource manager; sending to the statistical unit a message reporting congestion, based on information existing in the resource manager; and recording the congestion situation into a traffic measurement report by using the statistical unit.
