20140051360 | DEVICE AND METHOD FOR PERFORMING INTER-DEVICE COMMUNICATION - A device and method for performing inter-device communication are disclosed. The inter-device communication method includes searching for a second device supporting inter-device communication, receiving service information from the searched second device, determining that one of the first and second devices is a group owner and the other is a group client to compare the received service information of the second device with service information of a first device, receiving a group owner intent value of the second device from the second device, and setting a group owner intent value of the first device such that the group owner intent value of the device determined as the group owner is greater than the group owner intent value of the device determined as the group client to compare the group owner intent value of the first device with the group owner intent value of the second device. | 02-20-2014 |
20140079045 | DEVICE AND METHOD FOR PERFORMING INTER-DEVICE COMMUNICATION - A device and method for performing inter-device communication are disclosed. An inter-device communication method of a first device includes searching for a second device supporting inter-device communication, receiving network information from the searched second device, and determining that one of the first and second devices is a group owner based on the received network information of the second device and network information of the first device. The network information includes at least one selected from among type information indicating a server device or a client device, network support information, network necessity information, and network setting information. | 03-20-2014 |
20140314065 | METHOD AND DEVICE FOR SEARCHING FOR SUPPORTED SERVICE THROUGH WIFI DIRECT NETWORK - The present invention relates to a method and device that may determine a service provided by a WiFi device to be connected before connecting a WiFi direct network. According to at least one embodiment of the present invention, if a service for an owner device of a wireless communication group is discovered for in the process of discovering for a service for the wireless communication group, there is the advantage that is possible to more conveniently perform the service discovery process by obtaining supported service information on each device belonging to the group. In addition, if there is a currently unavailable service in the process of discovering for the service for the wireless communication group, there is the advantage that it is possible to provide information highly necessary for a user to determine network establishment by further providing information on the unavailable service. | 10-23-2014 |
20150351018 | DISCOVERY METHOD AND DEVICE IN A WIRELESS COMMUNICATION SYSTEM - An embodiment of the present invention entails a method in which discovery is effected by a first device supporting a WiFi direct service, the method comprising the steps of: scanning usable channels; switching channel to a first channel; and effecting a procedure relating to probe sending and receiving, together with a second device on the first channel. Here, the first channel is determined from either a time stamp or the scanning result. | 12-03-2015 |
20150373657 | METHOD AND APPARATUS FOR DEVICE-TO-DEVICE COMMUNICATION IN WIRELESS COMMUNICATION SYSTEM - The present invention relates to a method for device-to-device communication (D2D) in a wireless communication system. Particularly, the method is characterized in that when a device, which has been conducting device-to-device communication, additionally conducts device-to-device communication with a new device, a channel sequence of the device conducting the communication is determined, one of two devices conducting the device-to-device communication is determined as a reference device for channel synchronization and channel synchronization is thereby performed. | 12-24-2015 |
20150382287 | METHOD FOR FINDING INSTRUMENT FOR WI-FI DIRECT P2P (PEER TO PEER) COMMUNICATION AND APPARATUS THEREFOR - The present invention relates to a method for performing communication between terminals (D2D). Specifically, the method is characterized in that when a terminal communicating with another terminal is to perform an additional communication with yet another terminal, the channel sequence of the communicating terminal is determined, and one of the two terminals communicating with each other is defined as the channel synchronization reference terminal performing synchronization. | 12-31-2015 |
20160007335 | SLOT-BASED D2D COMMUNICATION METHOD AND APPARATUS - The D2D communication method may comprise the step of: transmitting, by a search device, a search request message through each of a plurality of channels in a search area, the search area corresponding to time resource allocated to integer multiple slots; receiving, by the search device, a search response message as a response to the search request message from a device found through at least one channel from among the plurality of channels in the search area, the search response message containing slot timing information and information on a first channel hopping pattern; synchronizing with the found device based on the slot timing information in a peering area by the search device; and performing communication with the found device, by the search device, on the basis of the information on the first channel hopping pattern in a communication area. | 01-07-2016 |
20160037323 | METHOD FOR MAKING DEVICE TO DEVICE COMMUNICATION IN WIRELESS COMMUNICATIONS SYSTEM AND APPARATUS THEREFOR - The present invention relates to a method for making device to device (D2D) communication. More specifically, the step of enabling a first device communicating with another device through channel hopping to find a second device for communication further includes the steps of: finding the second device based on a first channel hopping sequence in a first time interval within the entire find cycle during which the first device performs the channel hopping; and setting the first device so as to perform the channel hopping based on a second channel hopping sequence in a second time interval within the entire find cycle, wherein the entire find cycle of the first device is determined based on the second channel hopping sequence in the second time interval and the number of repeated second channel hopping sequences. | 02-04-2016 |
