首先，當第一用戶端直接通訊裝置71欲與直接通訊系統7中之其他用戶端直接通訊裝置連線時，第一用戶端直接通訊裝置71須先向後端網路75註冊。據此，第一用戶端直接通訊裝置71之收發器711傳送一註冊訊號710至後端網路75，以向後端網路75完成註冊。 First, when the first client direct communication device 71 is to be connected to other client direct communication devices in the direct communication system 7, the first client direct communication device 71 must first register with the backend network 75. Accordingly, the transceiver 711 of the first client direct communication device 71 transmits a registration signal 710 to the backend network 75 to complete registration with the backend network 75.

接著，由於後端網路75可依照前述之方式完成其他用戶端直接通訊裝置之註冊，因此，後端網路75便可記錄直接通訊系統7中所有用戶端直接通訊裝置之相關資訊，並據以判斷可互相連線之用戶端直接通訊裝置彼此是否位於通訊範圍內。具體而言，後端網路75於第一用戶端直接通訊裝置71註冊完畢後，便可判斷第一用戶端直接通訊裝置71與其可連線之一第二用戶端直接通訊裝置73之一位置關係。 Then, since the backend network 75 can complete the registration of other client direct communication devices in the foregoing manner, the backend network 75 can record information about all the direct communication devices of the client in the direct communication system 7, and according to In order to determine whether the direct communication devices that can be connected to each other are within the communication range of each other. Specifically, after the first-end direct communication device 71 is registered, the back-end network 75 can determine the location of the first user-side direct communication device 71 and one of the second-user direct communication devices 73 that can be connected. relationship.

隨後，當後端網路75根據位置關係判斷第一用戶端直接通訊裝置71與第二用戶端直接通訊裝置73彼此進入可通訊範圍，且準備進行探索互動後，後端網路75便可傳送一wi-fi直接連線資訊750至第一用戶端直接通訊裝置71，使得第一用戶端直接通訊裝置71可根據wi-fi直接連線資訊750，於稍後直接與第二用戶端直接通訊裝置73間以wi-fi模式建立連線。 Then, when the backend network 75 determines that the first client direct communication device 71 and the second client direct communication device 73 enter the communicable range according to the positional relationship, and is ready to perform the exploration interaction, the backend network 75 can transmit A Wi-fi directly connects the information 750 to the first user direct communication device 71, so that the first user direct communication device 71 can directly communicate with the second user terminal according to the wi-fi direct connection information 750. Connections are established between devices 73 in a wi-fi mode.

更進一步來說，當第一用戶端直接通訊裝置71之收發器711接收wi-fi直接連線資訊750後，由於wi-fi直接連線資訊750包含一第一用戶端網路位址IP1、一第二用戶端網路位址IP2以及一wi-fi頻道CH，因此，第一用戶端直接通訊裝置71便可直接利用後端網路75已提供之wi-fi連線所需相關資訊，與第二用戶端直接通訊裝置73建立一wi-fi直接通訊連線70。 Further, after the transceiver 711 of the first client direct communication device 71 receives the wi-fi direct connection information 750, the Wi-fi direct connection information 750 includes a first client network address IP1.

同樣地，當第一用戶端直接通訊裝置71欲與直接通訊系統7中之其他用戶端直接通訊裝置連線時，第一用戶端直接通訊裝置71須先向後端網路75註冊。據此，第一用戶端直接通訊裝置71之收發器711傳送註冊訊號710至後端網路75，以向後端網路75完成註冊。 Similarly, when the first client direct communication device 71 is to be connected to other client direct communication devices in the direct communication system 7, the first client direct communication device 71 must first register with the backend network 75. Accordingly, the transceiver 711 of the first client direct communication device 71 transmits the registration signal 710 to the backend network 75 to complete registration with the backend network 75.

接著，後端網路75於第一用戶端直接通訊裝置71註冊完畢後，便可判斷第一用戶端直接通訊裝置71與其可連線之第二用戶端直接通訊裝置73之位置關係。隨後，當後端網路75根據位置關係判斷第一用戶端直接通訊裝置71與第二用戶端直接通訊裝置73彼此進入可通訊範圍，且準備進行探索互動後，後端網路75先傳送一wi-fi建立要求訊息752至第二用戶端直接通訊裝置73。 Then, after the first-end direct communication device 71 is registered, the back-end network 75 can determine the positional relationship between the first-end direct communication device 71 and the second user-side direct communication device 73 that can be connected. Then, when the backend network 75 determines that the first client direct communication device 71 and the second client direct communication device 73 enter the communicable range according to the positional relationship, and is ready to perform the exploration interaction, the backend network 75 first transmits one. The wi-fi establishes the request message 752 to the second client direct communication device 73.

隨後，第二用戶端直接通訊裝置73之收發器731接收wi-fi建立要求訊息752後，處理器733便根據wi-fi建立要求訊息752決定第一用戶端網路位址IP1、第二用戶端網路位址IP2以及wi-fi頻道CH，並透過收發器731將第一用戶端網路位址IP1、第二用戶端網路位址IP2以及wi-fi頻道CH回傳至後端網路75。 Then, after the transceiver 731 of the second client direct communication device 73 receives the wi-fi establishment request message 752, the processor 733 determines the first user network address IP1 and the second user according to the wi-fi establishment request message 752. The network address IP2 and the wi-fi channel CH are transmitted back to the back-end network through the transceiver 731, the first client network address IP1, the second client network address IP2, and the wi-fi channel CH.

如此一來，後端網路75便可將包含第一用戶端網路位址IP1、第二用戶端網路位址IP2以及wi-fi頻道CH之wi-fi直接連線資訊750傳送至第一用戶端直接通訊裝置71，使得第一用戶端直接通訊裝置71根據wi-fi直接連線資訊750，於稍後直接與第二用戶端直接通訊裝置73間以wi-fi模式建立連線。 In this way, the backend network 75 can transmit the wi-fi direct connection information 750 including the first client network address IP1, the second client network address IP2, and the wi-fi channel CH to the first A client direct communication device 71 causes the first client direct communication device 71 to establish a connection in the wi-fi mode directly with the second client direct communication device 73 according to the wi-fi direct connection information 750.

類似地，當第一用戶端直接通訊裝置71之收發器711接收wi-fi直接連線資訊750後，由於wi-fi直接連線資訊750包含第一用戶端網路位址IP1、第二用戶端網路位址IP2以及wi-fi頻道CH，因此，第一用戶端直接通訊裝置71之處理器713便可根據第一用戶端網路位址IP1以及第二用戶端網路位址IP2，利用收發器711與第二用戶端直接通訊裝置73於wi-fi頻道CH建立wi-fi直接通訊連線70。 Similarly, when the transceiver 711 of the first user direct communication device 71 receives the wi-fi direct connection information 750, since the wi-fi direct connection information 750 includes the first user network address IP1, the second user The network address IP2 and the wi-fi channel CH, so that the processor 713 of the first user direct communication device 71 can be based on the first client network address IP1 and the second client network address IP2. The Wi-fi direct communication connection 70 is established on the wi-fi channel CH by the transceiver 711 and the second client direct communication device 73.

需特別說明，當第一用戶端直接通訊裝置71與第二用戶端直接通訊裝置73直接建立wi-fi直接通訊連線70前，仍需透過探索互動完成連線。詳言之，第一用戶端直接通訊裝置71之收發器711基於第一用戶端網路位址IP1，於一訊號偵測週期(未繪示)中，自具有第二用戶端網路位址IP2之第二用戶端直接通訊裝置73接收一探索信息730。 It should be specially noted that before the first user direct communication device 71 and the second user direct communication device 73 directly establish the wi-fi direct communication connection 70, the connection needs to be completed through the exploration and interaction. In detail, the transceiver 711 of the first client direct communication device 71 is based on the first client network address IP1, and has a second client network address in a signal detection period (not shown).
