Abstract
A method for managing multiple, independent, simultaneous calls between a mobile communications network and a subscriber terminal. For each subscriber terminal there is a first upper limit which is related to the capacity of its radio interface. Calls are limited to a number which does not result in exceeding the first upper limit. There is also, for the number of simultaneous calls, at least one second upper limit which is not lower than zero. The actual number of simultaneous calls between the network and the subscriber terminal is monitored. A new call to/from the subscriber terminal is allowed only if the actual number of simultaneous calls is less than the at least one second upper limit. Preferably, there is a separate second upper limit for each subscriber and for each of several call types, such as voice, data and fax calls.
