A power source equipment is configured to provide a power to a powered device in a power over Ethernet. The power source equipment includes a first port, a second port, and a control circuit. The first port is configured to perform a power classification on the powered device, and provide a first voltage to the powered device in a first stage. The second port is configured to provide a second voltage to the powered device in a second stage. The control circuit is configured to disable the second port in the first stage, and configured to control the second port to output the second voltage and increase the first voltage in the second stage.

Power source equipment and power supply control method

An antenna control method comprises obtaining a plurality of radio frequency signal parameters respectively in a plurality of measuring beam directions, generating a plurality of parameter groups according to the plurality of radio frequency signal parameters, selecting a target beam direction from the plurality of measuring beam directions according to the plurality of parameter groups, and controlling an antenna to transmit and receive signals in the target beam direction. In said antenna control method, two adjacencies of the plurality of measuring beam directions have an angle difference therebetween, and each of the plurality of parameter groups comprises more than one of the plurality of radio frequency signal parameters.

Antenna control method and communication system control method

A method of dynamic adjusting a generation frequency of messages in vehicular networks is provided, including: receiving updating requests and emergent degree of the vehicle event, and then determining whether the generation frequency of messages meets the dynamic change of the vehicle, if not satisfied, selecting a different adjustment method according to the event emergent degree. When the event is emergent, its generation frequency can be raised immediately by an interruptive adjustment and to suppress the generation frequency of messages of the others. Conversely, adjusting its generation frequency by a progressive adjustment and reducing the generation frequency of messages of the other lower-priority vehicles. According to the present disclosure, it prevents lower priority messages from occupying the channel overly, and emergency messages with higher priority can be satisfied immediately when it needed.

System of dynamically adjusting generation frequency of messages in vehicular networks and method thereof

Embodiments of the present invention are directed to methods and systems for generating and revoking, as well as validating, certificates used to protect communications within networks while maintaining privacy protection. In the context of a method, certificate generation and revocation with privacy preservation comprises determining a secret value to be used by a certificate authority and an entity; constructing a key tree based on the secret value, wherein the leaves of the key tree represent derived keys for the certificates for the entity; and generating certificates for the entity based in part on the key tree leaves. The method further comprises determining that one or more of the certificates should be revoked; determining a minimum key node set that covers the certificates to be revoked; adding the minimum key node set to a certificate revocation list; and providing the certificate revocation list to one or more entities. Corresponding apparatuses and computer program products are also provided.

Method for certificate generation and revocation with privacy preservation

A data scheduling module, a data scheduling method and computer program product thereof for a wireless communication apparatus are provided. The data scheduling method comprises the following steps: determining that the frame length of a second data transmission interval is not smaller than a frame length of a first data transmission interval; summing at least one first data and at least one second data according to the frame length of the second data transmission interval; calculating an average value according to the frame length of the second data transmission interval and the summed result; calculating an aggregate data transmission interval according to a data transmission capacity, the average value, and an integer adjusting value; and transmitting the at least one first data and the at least one second data via a plurality of frames in accordance with the aggregate data transmission interval.

Data scheduling module, method, and computer program product thereof for a wireless communication apparatus

A fleet maintenance method for generating a suggested speed for each vehicle in a fleet to maintain the vehicle in the fleet is provided. In the fleet maintenance method, vehicles are clustered into a plurality of sub-fleets, and in each sub-fleet, one vehicle is selected as a leader vehicle and the other vehicles are considered as member vehicles. Besides, a position coordinate and a speed of each vehicle in each sub-fleet are obtained, and the position coordinate is converted into a corresponding linear coordinate. In addition, a sub-fleet gravity center of each sub-fleet and a fleet gravity center of the entire fleet are calculated according to the linear coordinates. Moreover, a suggested speed of each leader vehicle is generated according to a gravity center distance of the leader vehicle, and a suggested speed of each member vehicle is generated.

Fleet maintenance method and in-vehicle communication system
