Abstract
Upon a user equipment attaching to a core network of a cellular communications network system, an IP address is allocated to the user equipment by a network device of the core network, for tunneling data relating to the user equipment between the network device and an application server. The IP address is allocated from a subnetwork, and the allocating is performed based on path monitoring information. If the path monitoring information contains an IP address of at least one subnetwork, the subnetwork is selected from the at least one subnetwork. Then it is checked if the path monitoring information contains a combination of the subnetwork's IP address and the application server's IP address. In case the combination is not contained in the path monitoring information, a path indicated by the combination of the subnetwork's IP address and the application server's IP address is added to the path monitoring information.
