Communication is established between a plurality of users through mobile computing devices. A server communicates with the mobile computing devices. Unique User Identifiers (UUIDs) are registered on the server through a network, and a database connected to the server stores the uploaded UUIDs and associated data. The server receives and sends communications to and from the mobile computing devices, receives UUIDs and associated data from mobile computing devices, and sends UUIDs and associated data to one or more mobile computing devices.

A communications method includes determining, by a first platoon member, at least one second platoon member, where the first platoon member and the at least one second platoon member belong to a same platoon, and signal quality of a communication link from the first platoon member to each second platoon member is less than a first preset quality threshold, determining, by the first platoon member, a target communications node, where signal quality of a communication link from the target communications node to each second platoon member is greater than or equal to the first preset quality threshold, and sending, by the first platoon member, to-be-sent data to each second platoon member through the target communications node.

A method of automatically creating trust communities in a fleet of devices. The method includes finding candidate devices in a fleet of devices via one or more candidate discovery techniques and generating device-related data based on the candidate devices that are found, analyzing the device-related data via an analytics engine and creating one or more fleet orchestrator device lists based on the analysis of the device-related data, and automatically creating one or more new trust communities or suggesting joining one or more previously existing trust communities based at least on the one or more fleet orchestrator device lists for the candidate devices, wherein the one or more new trust communities or previously existing trust communities include at least a sub-set of the devices in the fleet, and wherein at least one of the managed devices in the sub-set of devices is configured as a root device to publish files via a file sharing function.

A method for dynamic group management. The method which may be performed by a vertical application layer server comprises receiving first dynamic information for a group of communication devices from a group management server. The method further comprises transmitting second dynamic information for the group of communication devices to an application specific server, based at least in part on the first dynamic information for the group of communication devices. In some instances, the application specific server may get the dynamic information about group membership effectively during dynamic group management.

A messaging system for exchanging messages between nodes in a network via a broker that uses a publish-subscribe message protocol, which nodes have object identifications (IDs). Messages between the nodes are routed using the object IDs of the nodes. Secure communication is provided using authentication according to digital certificates being used as first and second tiers by a commissioning broker and a data broker, respectively, in which the second tier certificate used by the data broker has a shorter lived expiration time.

A mobile network platform creates a device group according to a member device supporting a mobile network multicast communication manner in a Machine-to-Machine Communications (M2M) group, generates an identifier of an external group corresponding to the device group, and requests a service capability exposure function (SCEF) to create the external group according to the identifier of the external group and an external device identifier of the member device supporting the mobile network multicast communication manner. When receiving an access request for the M2M group, the mobile network platform obtains the device group in the M2M group, learns of the corresponding external group, and then requests the SCEF to access the member device in the external group in a multicast communication manner. Hence, an amount of information generated due to interaction between an M2M platform and an M2M device is reduced, while reducing resource overheads.

A donor communication station transmits a unicast transmission comprising a plurality of device data sets where each device data set directed to each of a plurality of user equipment (UE) devices. A relay node receives the unicast transmission and retransmits the data sets in a broadcast transmission over a broadcast communication channel to the plurality of UE devices. In one example, the donor communication station encodes data for multiple user equipment (UE) devices by applying broadcast encoding to the data for each device before applying outer encoding to the data. The dual encoded data is transmitted to the relay node over a dedicated channel. The relay node applies outer decoding to the dual encoded data to retrieve the broadcast encoded data. The relay node then transmits the broadcast encoded device data in a broadcast transmission without outer encoding.
