1. A mobile wireless communication device configured to communicate with a location management server over a wireless communication network, the mobile wireless communication device being configured to be part of a cluster of mobile wireless communication devices managed on the basis of a clustering protocol, the clustering protocol configured to select one of the mobile wireless communication devices of the cluster of mobile wireless communication devices as a cluster head for representing the cluster of mobile wireless communication devices, the mobile wireless communication devices of the cluster of mobile wireless communication devices being either in a network-connected mode or a network-idle mode relative to the wireless communication network,wherein, in case the mobile wireless communication device is the cluster head, the mobile wireless communication device is configured to select one of the mobile wireless communication devices of the cluster of mobile wireless communication devices, including the mobile wireless communication device itself, being in the network-connected mode as a cluster rapporteur for communicating with the location management server;

  • andwherein, in case the mobile wireless communication device is not the cluster head and is in the network-connected mode, the mobile wireless communication device is configured to be selected by the cluster head as the cluster rapporteur for communicating with the location management server;

    wherein, in case the mobile wireless communication device is the cluster rapporteur, the mobile wireless communication device is configured to send cluster location management information to the location management server, wherein the cluster location management information comprises information about a location of the cluster head and/or information about respective locations of the mobile wireless communication devices of the cluster of mobile wireless communication devices, and wherein, in case the mobile wireless communication device is not the cluster rapporteur, the mobile wireless communication device is configured to refrain from sending device location management information to the location management server, wherein the device location management information comprises information about the location of the wireless communication device; and

    wherein, in case the mobile wireless communication device is the cluster head, the mobile wireless communication device is configured to select itself as the cluster rapporteur for communicating with the location management server, when the mobile wireless communication device is in the network-connected mode or the network-idle mode and the other mobile wireless communication devices of the cluster of mobile wireless communication devices are in the network-idle mode.
