Abstract
Abstract The invention relates to a communication system with at least two different access systems, wherein a first access system is capable of handling a first number of communications between a mobile user equipment (MUE) and the first access system and wherein a second access system is capable of handling a second number of communications between the mobile user equipment (MUE) and the second access system. According to the invention the communication system contains at least one means for making at least one decision, which communication or communications are handed over in the case that the mobile user equipment (MUE) moves between the first access system and the second access system and at least one means for executing the at least one decision. The invention further relates to a method for managing a communication system.
