As shown in FIG. 2, in the wireless communication environment 2000, the wireless device 100 has a first multimedia device 400 and a second multimedia device 500. The first multimedia device 400 has a first wireless signal source 40 that can emit a high power wireless signal 42. The second multimedia device 300 has a second wireless signal source 50 that can emit a high power wireless signal 52.
當無線裝置100同時接收到第一無線訊號源40所發出之高功率無線訊號42及第二無線訊號源50所發出之高功率無線訊號52，應用控制模組12會將所接收到的高功率訊號42及高功率訊號52之訊號強度進行比較。若所接收到的高功率訊號42的訊號強度較強，應用控制模組12會將無線裝置100連結至第一無線訊號源40，透過無線傳輸模組14將無線裝置100中的檔案經由第一無線訊號源40傳送至第一多媒體裝置400，並透過第一多媒體裝置400加以播放；若所接收到的高功率訊號52的訊號強度較強，應用控制模組12會將無線裝置100連結至第二無線訊號源50，透過無線傳輸模組14將無線裝置100中的檔案經由第二無線訊號源50傳送至第二多媒體裝置500，並透過第二多媒體裝置500加以播放。When the wireless device 100 simultaneously receives the high-power wireless signal 42 from the first wireless signal source 40 and the high-power wireless signal 52 from the second wireless signal source 50, the application control module 12 will receive the received high power. The signal strengths of signal 42 and high power signal 52 are compared. If the received signal strength of the high-power signal 42 is strong, the application control module 12 connects the wireless device 100 to the first wireless signal source 40, and transmits the file in the wireless device 100 through the wireless transmission module 14 through the first The wireless signal source 40 is transmitted to the first multimedia device 400 and played through the first multimedia device 400. If the received signal strength of the high power signal 52 is strong, the application control module 12 will transmit the wireless device. 100 is connected to the second wireless signal source 50, and the file in the wireless device 100 is transmitted to the second multimedia device 500 via the second wireless signal source 50 through the wireless transmission module 14 and transmitted through the second multimedia device 500. Play.
若無線裝置100原本係為連結至第二無線訊號源50的狀態，當所接收到的第一無線訊號源40所發出的高功率無線訊號42高於第一無線訊號源50所發出的高功率無線訊號52時，則應用控制模組12會中斷與第二無線訊號源50之無線連結，並將無線裝置100連結至第一無線訊號源40。上述之高功率無線訊號42、52可為WiFi訊號。If the wireless device 100 is originally connected to the second wireless signal source 50, the high-power wireless signal 42 sent by the received first wireless signal source 40 is higher than the high power generated by the first wireless signal source 50. In the case of the wireless signal 52, the application control module 12 interrupts the wireless connection with the second wireless signal source 50 and connects the wireless device 100 to the first wireless signal source 40. The high power wireless signals 42, 52 described above may be WiFi signals.
第二實施例中，應用控制模組12會比較所接收到的高功率無線訊號42及高功率無線訊號52的訊號強度，將無線裝置100連結至第一無線訊號源40或第二無線訊號源50，以將無線裝置100的檔案透過第一多媒體裝置400或第二多媒體裝置500加以播放。例如，使用者欲將手中的智慧型手機上之檔案透過WiFi訊號在大型顯示器上播放，而智慧型手機接收到多個WiFi訊號時，可比較所接收到的WiFi訊號的訊號強度，將智慧型手機連結至所接收到之WiFi訊號強度最大的大型顯示器，並將智慧型手機上的檔案透過WiFi訊號傳送至該大型顯示器加以播放。因此，當智慧型手機係隨著使用者移動時，可根據接收到顯示裝置傳來的訊號強度變化，而判斷使用者所欲接近之顯示裝置，以自動地將智慧型手機連結至該顯示裝置。In the second embodiment, the application control module 12 compares the received signal strengths of the high-power wireless signal 42 and the high-power wireless signal 52 to connect the wireless device 100 to the first wireless signal source 40 or the second wireless signal source. 50. The file of the wireless device 100 is played through the first multimedia device 400 or the second multimedia device 500. For example, the user wants to play the file on the smart phone in the hand on the large display through the WiFi signal, and the smart phone can compare the signal strength of the received WiFi signal when receiving the plurality of WiFi signals, and the smart type The mobile phone is connected to the large display with the strongest received WiFi signal, and the file on the smart phone is transmitted to the large display through the WiFi signal for playback. Therefore, when the smart phone moves with the user, the display device that the user wants to access can be determined according to the change of the signal intensity received from the display device to automatically connect the smart phone to the display device. .
透過本發明之方法，無線裝置可根據其當下的位置而自動地切換與無線訊號源的連結。因此，在無線裝置被頻繁地移動的情況下，無線裝置可以選擇適切的無線連結，而不須透過使用者重新設定的方式反覆地切換無線裝置的無線連結。With the method of the present invention, the wireless device can automatically switch the connection to the wireless signal source based on its current location. Therefore, in the case where the wireless device is frequently moved, the wireless device can select an appropriate wireless connection without repeatedly switching the wireless connection of the wireless device by means of user resetting.
