METHOD AND SYSTEM FOR SERVICE ALLOCATION IN COMMUNICATION NETWORKS, RELATED NETWORK AND COMPUTER PROGRAM PRODUCT THEREFOR

摘要

A system for controlling, in a multi-resource communication network (GSM, UMTS, WLAN), the delivery of services by at least one resource capable of simultaneously delivering, within a maximum joint service capacity, at least one first type of service (e.g. voice) to a first set of users and a second type of service (e.g. data) to a second set of users. The increase in the first set of users is capable, of causing a decrease in the capacity to serve new users of said second set of users. At least one module (50; 11, 22, 33) for estimating a parameter representing the probability that, in a given time interval, the number of service requests of said second type is such as not to cause said maximum service capacity to be reached. In the presence of a service request of the first type, the estimation module (50; 11, 22, 33) compares the parameter with a respective threshold value and indicates the acceptability of the service request of said first type if the aforesaid parameter exceeds said respective threshold. If the parameter is lower than the threshold value, then the estimation module (50; 11, 22, 33) evaluates the possible decrease in the capacity to serve new users of the second set of users which can be induced by the acceptance of said request of said first type of service and then compares the possible decrease with a respective decrease threshold value. The service request of the first type is then accepted or blocked, depending on whether the possible decrease is lower or higher than the decrease threshold value.
