The user direct-mode communication apparatus broadcasts a discovery signal based on the user authenticated identification. The serving direct-mode communication apparatus receives the discovery signal after the user direct-mode communication apparatus enters a default serving range, and provides interactive information to the user direct-mode communication apparatus according to the discovery signal and based on the serving authenticated identification. | 08-08-2013 |
20130294432 | DIRECT MODE COMMUNICATION SYSTEM AND COMMUNICATION ATTACHING METHOD THEREOF - A direct-mode communication system comprises a first client direct-mode communication apparatus and a backhaul network. The first client direct-mode communication apparatus transmits a register signal to the backhaul network to register with the backhaul network. After the first client direct-mode communication apparatus is registered, the backhaul network determines a location relationship between the first client direct-mode communication apparatus and a second client direct-mode communication apparatus, and transmits a wi-fi connection signal to the first client direct-mode communication apparatus according to the location relationship. The first client direct-mode communication apparatus creates a wi-fi direct-mode communication connection with the second client direct-mode communication apparatus according to the wi-fi connection signal. | 11-07-2013 |
20130294433 | DIRECT MODE COMMUNICATION SYSTEM AND COMMUNICATION ATTACHING METHOD THEREOF - A direct-mode communication system includes a first client direct-mode communication apparatus and a first backhaul network. The first client direct-mode communication apparatus transmits a proximity notification request to a second backhaul network via the first backhaul network so that the second backhaul network returns a proximity notification acknowledgement (ACK) signal. The first backhaul network receives a piece of first client location information and a piece of second client location information from the first direct-mode communication apparatus and the second backhaul network respectively, and determines a location relationship accordingly. The first backhaul network transmits a Wi-Fi connection signal to the first client direct-mode communication apparatus according to the location relationship. The first client direct-mode communication apparatus establishes a direct-mode communication connection with a second client direct-mode communication apparatus according to the Wi-Fi connection signal. | 11-07-2013 |
20130294437 | EVOLVED PACKET CORE LESS DIRECT MODE COMMUNICATION SYSTEM AND COMMUNICATION ATTACHING METHOD THEREOF - An evolved packet core less direct-mode communication system and a communication attaching method thereof are provided. The evolved packet core less direct-mode communication system comprises a client direct-mode communication apparatus and a server direct-mode communication apparatus. The server direct-mode communication apparatus transmits a synchronization signal to the client direct-mode communication apparatus. The client direct-mode communication apparatus synchronizes to the server direct-mode communication apparatus according to the synchronization signal and establishes a communication connection with the evolved packet core less direct-mode communication system after synchronization. | 11-07-2013 |
20140098805 | DIRECT MODE COMMUNICATION SYSTEM AND COMMUNICATION ATTACHING METHOD THEREOF - A direct-mode communication system comprises a first client direct-mode communication apparatus and a backhaul network. The first client direct-mode communication apparatus transmits a register signal to the backhaul network to register with the backhaul network. After the first client direct-mode communication apparatus is registered, the backhaul network determines a location relationship between the first client direct-mode communication apparatus and a second client direct-mode communication apparatus. The backhaul network transmits a piece of wi-fi connection information to the first client direct-mode communication apparatus according to the location relationship. The first client direct-mode communication apparatus creates a wi-fi direct-mode communication connection with the second client direct-mode communication apparatus according to the piece of wi-fi connection information. | 04-10-2014 |
20140192680 | WIRELESS DEVICE AND WIRELESS NETWORK SYSTEM - A wireless device and a wireless network system are provided. The wireless device is configured to discover an under-discovered wireless device, and a first network server serves the under-discovered wireless device. The under-discovered wireless device transmits a terminal signal to the first network server at a specific frequency and in a specific period. The wireless device includes a transceiver and a processor electrically connected to the transceiver. The processor obtains a piece of feature information regarding to the under-discovered wireless device by listening to the terminal signal via the transceiver, and identifies that the under-discovered wireless device is in a discovery coverage of the wireless device based on a determination result that the feature information or a normalized feature information is higher than a predetermined threshold. | 07-10-2014 |
20140295861 | NETWORK SYSTEM AND RESOURCE ALLOCATION METHOD THEREOF - A network system and a resource allocation method thereof are provided. The network system includes a base station and a mobile station. The base station retrieves mobile station information from the mobile station via a network connection, and decides a communication allocation between the base station and the mobile station according to the mobile information. The communication allocation records one or a combination of a common base station identification and a dedicated base station identification. After the base station transmits the communication allocation to the mobile station, the mobile station communicates with the base station according to the communication allocation via one or a combination of the common base station identification and the dedicated base station identification. | 10-02-2014 |
