摘要:
Methods and apparatuses are provided for controlling power transmission in a power transmitter. A first message including a first voltage and a second voltage that is greater than the first voltage, is received from at least one power receiver. Power is transmitted to the at least one power receiver. A second message including a third voltage measured at the at least one power receiver during power transmission from the power transmitter, is received from the at least one power receiver. An amount of the power is adjusted based on whether the third voltage is between the first voltage and the second voltage. The first voltage is a minimum voltage for the at least one power receiver.

A method for acquiring a service category table required for finding a service includes acquiring information on a latest service category table by identifying version information of a service category table from a broadcasting signal received from adjacent devices during a process of searching for a device supporting a service desired among devices, and acquiring a service category table of a latest version by establishing a session connection with a device supporting the service category table of the latest version based on the information. By acquiring the information on the latest service category table, a session connection with only the device providing the desired service is established so that an optimized session connection establishing process can be performed and a total network capacity can be efficiently managed. Also, the latest service category table can be acquired from the session-connected device, and thus a new service can be easily identified.

A method of providing location information of a target Secure User Plane Location (SUPL) Enabled Terminal (target SET) while protecting privacy of a user of the target SET in a Home-SUPL Location Center (H-SLC) providing the location information of the target SET, and the H-SLC, are provided. The method includes receiving a location request message from a requester, transmitting an SUPL INITiation (SUPL INIT) message by using a first session IDentifier (ID) to the target SET, the first session ID including a real ID of the target SET, transmitting a Positioning DATA (PDATA) message by using a second session ID to the Home-SUPL Positioning Center (H-SPC), the second session ID including a pseudo-ID for secure connection between the H-SLC and the H-SPC, receiving a positioning result of the target SET from the H-SPC, and transmitting the positioning result to the requester.
摘要:
Methods and apparatuses are provided for controlling power transmission in a power transmitter. Voltage information including a minimum voltage, a maximum voltage, and a first voltage, is received from each of a plurality of power receivers. Power is transmitted to the plurality of power receivers based on the voltage information. A respective report about a power reception condition is received from each of the plurality of power receivers while transmitting the power. Each respective report includes a measured voltage at a corresponding power receiver of the plurality of power receivers. A power receiver is selected from among the plurality of power receivers based on the received reports. An amount of the power is adjusted by reducing a difference between a first voltage of the selected power receiver and a measured voltage of the selected power receiver.

摘要:
Methods and apparatus are provided for controlling power transmission. A minimum voltage and a maximum voltage receivable at the at least one power receiver, a reference voltage used to divide a range between the minimum voltage and the maximum voltage, and a demanded voltage required by the at least one power receiver, are received from at least one power receiver. A report about a power reception condition is received from the at least one power receiver. The report includes a measured voltage at the at least one power receiver during power transmission from the power transmitter. It is determined whether the measured voltage is between the minimum voltage and the reference voltage. Power is adjusted and supplied when the measured voltage is not between the minimum voltage and the reference voltage.
