1. A method of a first wireless communication device, the first wireless communication device comprised in a cluster of cluster members comprising the first wireless communication device and one or more second wireless communication devices;
wherein at least one cluster member is in a cluster communication mode, the first wireless device is in a cellular communication mode, and each of the cluster members is associated with a shared cluster subscription identifier, the identifier associated with a subscription providing communication between a network node of a cellular communication network and one or more cluster members in a cluster communication mode; and
wherein a cluster member in a cluster communication mode comprises one of:
a cluster communication gateway role comprising:
transmitting a cluster communication beacon signal;
maintaining a communication link to the network node;
maintaining peer-to-peer communication links to the one or more second wireless communication devices;
forwarding communication from the network node to the one or more second wireless communication devices; and
forwarding communication from the one or more second wireless communication devices to the network node; and
a cluster internal communication role comprising:
maintaining at least a peer-to-peer communication link to a gateway of the one or more second wireless communication devices, the gateway having the cluster communication gateway role; and
communicating indirectly via the gateway with the network node; and
the method comprising:
scanning, in a cellular communication mode, a received signal for a cluster communication beacon signal, wherein in a cellular communication mode the first wireless device communicates directly with the network node;
in response to the cluster communication beacon signal being found, determining whether the beacon signal is based on the shared cluster subscription identifier indicating that the beacon signal is associated with the subscription;
in response to the cluster communication beacon signal being associated with the subscription:
determining, based on the cluster communication beacon signal, an identity of the gateway;
transmitting, to the gateway, a cluster communication attach request;
receiving, from the gateway, a cluster communication attach response comprising a cluster communication attach acknowledgement or a cluster communication attach non-acknowledgement; and
in response to the cluster communication attach response comprising a cluster communication attach acknowledgement, transferring from the cellular communication mode to the cluster communication mode and assuming the cluster internal communication role.
