A cellular base station connected to a communication network is adapted to provide communication services to a plurality of mobile devices. A server connected to the communication network includes a first publish-subscribe broker communications facility as part of a publish-subscribe broker network including one or more publish-subscribe broker communications facilities. The publish-subscribe broker network is operable to distribute published data packets between entities that have published data packets and entities that have subscribed to receive the published data packets via the publish-subscribe broker network. A second entity connected to any of the publish-subscribe broker communications facilities in the publish-subscribe broker network accepts communications from the mobile device if the second entity subscribes to data published by the mobile device through the publish-subscribe broker communications facility to which the second entity is connected.

The present invention relates to a security message transmission method and apparatus. The method includes: generating, by a vehicle terminal, a first security message, where the first security message carries message type information; adding priority indication information of the security message to a geographic information layer according to the message type information, and obtaining a second security message; determining, at a Media Access Control (MAC) layer, a transmission path of the security message according to the priority indication information; and sending the second security message to a recipient by using a physical layer corresponding to the determined transmission path, so that the recipient performs forwarding processing on the second security message. According to the present invention, a security message is forwarded to a vehicle terminal within a predetermined distance range in a manner of combining a VDC technology and an LTE cellular network.

A wireless RF access node is connected to a communication network and is adapted to provide communication services to a plurality of mobile entities. A server is connected to the communication network, wherein the server comprises a first publish-subscribe broker communications facility as part of a publish-subscribe broker network including one or more publish-subscribe broker communications facilities. The publish-subscribe broker network is operable to distribute published data packets between entities that have published data packets and entities that have subscribed to receive the published data packets via the publish-subscribe broker network. A second entity connected to any of the publish-subscribe broker communications facilities in the publish-subscribe broker network accepts communications from a first mobile entity if the second entity subscribes to data published by the first mobile entity through the publish-subscribe broker communications facility to which the second entity is connected.

A wireless device receives at least one downlink control information (DCI) indicating uplink resources in a set of m consecutive subframes 0 to m1. The wireless device performs an LBT procedure on a channel to make a transmission in subframe k+1, if the wireless device cannot access the channel for a transmission in subframe k, k {0, . . . , m2}.

Dynamically identifying and utilizing an opportunistic device by performing at least the following within a discovery offloading module: receive an offloading alert message from a service device, wherein the offloading alert message indicates the service device is unable to provide one or more services to the client device, receive a discovery message from a candidate device, wherein the discovery message indicates the candidate device is capable of performing the services provided to the client device, select, using the dedicated execution environment, an opportunistic service device based on the discovery message from the candidate device; and trigger the restart of host execution instruction within the client device by obtaining the one or more services from the opportunistic service device, wherein the discovery offloading module operates independently from the host execution instructions within the client device.

The present invention discloses a transmission control method, apparatus and system, so as to effectively utilize network link resources. The method of the present invention includes: acquiring link status information about a network; determining recommended values of TCP transmission parameters according to the link status information; and performing TCP transmission according to the determined recommended values of the parameters. The present invention can enable TCP transmission status to reflect network congestion status more real, prevent a congestion misjudgment from occurring, and improve a utilization ratio of link resources in a network.

This data-flow control device has: a device-side metadata acquisition means that acquires device-side metadata about a plurality of devices; an application-side metadata acquisition means that acquires application-side metadata about an application that uses data provided by a device; a storage means that stores each type of metadata; and a temporary matching means that, when the device-side metadata or the application-side metadata is newly registered, determines and reports whether a temporary pair is present, said temporary pair comprising the newly registered device-side metadata or application-side metadata and counterpart device-side metadata or the application-side metadata that meets a matching condition and was registered prior to the newly registered device-side metadata or application-side metadata.

In a sensor relay apparatus (10), a communication control unit (13) receives sensor data from a sensor terminal (ST) via a terminal module (11) when a transmission data amount related to the sensor data to be transmitted from the sensor terminal (ST) is equal to or greater than a determination threshold. This can reduce the overhead time taken at the time of the transmission of the sensor data.

A method for controlling a suspension component of a vehicle, in which a control unit of the suspension component continuously generates a plurality of control requirements according to a generation clock frequency, each requirement comprising a control value, for an actuator of the suspension component. A bus system of the vehicle continuously transmits to the actuator the control requirements generated by the control unit according to a transmission clock frequency. The actuator calculates a target output value for the suspension component from the control value of each transmitted control requirement and an actual output value of the suspension component, and adjusts the suspension component corresponding to the calculated target output value.
