A network management entity for a communication network includes: a processor configured to operate a logic subnetwork in the communication network, wherein the logic subnetwork is configured to enable a first communication device to communicate via the logic subnetwork and to provide the first communication device with further resources of the logic subnetwork; and a communication interface configured to receive a position signal indicating a position of a second mobile communication device. The processor is further configured to incorporate the second mobile communication device in the logic subnetwork to provide the logic subnetwork with at least one resource of the second mobile communication device if the position of the second mobile communication device is within a defined position range.
