Description:
TECHNICAL FIELD 
     The disclosure relates to data transmission technology in the field of mobile communication, and more particularly to a method, device and system for transmitting wireless data. 
     BACKGROUND 
     Currently, information interaction is performed only between mobile terminals and base stations in an existing communication system. In other words, each mobile terminal independently communicates with a base station to which the mobile terminal belongs, whereas there is no direct interactive relationship between individual mobile terminals. As shown in  FIG. 1 , specifically, a local mobile terminal  1  or a mobile terminal  2  sends information to a local base station  1  to which the local mobile terminal  1  or the mobile terminal  2  belongs. The base station  1  then sends the received information to a target base station to which a target mobile terminal belongs, e.g., a base station  2 . The base station  2  then sends the received information to the target mobile terminal, e.g., a mobile terminal  3  or a mobile terminal  4 , so as to achieve communication between the local mobile terminal and the target mobile terminal. The involved communication mode is referred to as Wide Area Network (WAN) communication. Since a local terminal communicates with a base station only through a main transmission line, the transmission rate will be very low when the local mobile terminal transmits a relatively large volume of data to the local base station, thus reducing the transmission efficiency. In addition, the local mobile terminal will fail to send data to the local base station in the case that there is a failure on a transmission line between the local mobile terminal and the local base station, thus a user cannot communicate normally. 
     Moreover, when a mobile terminal is to transmit a larger volume of data, network capacity can be improved only by capacity extension of a base station, so as to improve the data transmission efficiency. However, the capacity extension of the base station will cost a great deal of financial and material resources and the capacity of the base station cannot be extended unlimitedly. 
     In addition, all short distance transmission systems of the mobile terminal, such as a Wireless Fidelity (Wi-Fi) transmission system and a Bluetooth transmission system, can implement short distance communication between mobile terminals. The short distance communication refers to Local Area Network (LAN) communication. However, such LAN communication is isolated from WAN communication and the two communication modes cannot be applied in combination, thus a short distance transmission system of a mobile terminal in an idle state cannot often be utilized adequately and short distance communication resources of the mobile terminal are wasted. 
     SUMMARY 
     In view of this, the disclosure is intended to provide a method, device and system for transmitting wireless data, so as to be capable of adequately utilize short distance communication resources of a mobile terminals and improve the data transmission efficiency of the mobile terminal.

     Step  702 : Each relay mobile terminals that has received the request send a sign of network entry certification to the local mobile terminal respectively. 
     Step  703 : The local mobile terminal takes a part of short distance transmission systems in an idle state as available short distance transmission systems according to the received signs of network entry certification, and takes the rest of the short distance transmission systems in the idle state as backup short distance transmission systems. If the states of the short distance transmission systems identified by all signs of network entry certification are busy, then the local mobile terminal sends, according to an existing transmission mode, data to a base station to which the local mobile terminal belongs. 
     For example, if there are 30 signs of network entry certification identifying the short distance transmission system in an idle state in the received signs of network entry certification, then 20 short distance transmission systems in an idle state are taken as available short distance transmission systems and the other 10 short distance transmission systems in an idle state are taken as backup short distance transmission systems. 
     Step  704 : The local mobile terminal splits, according to the amount of the available short distance transmission systems, the data to be sent into multiple data packages the amount of which is the same as the amount of the available short distance transmission systems, and the local mobile terminal numbers the data packages to make each data package have its own serial number. 
     If it is assumed that there are  20  available short distance transmission systems and one base station, then the data to be sent are split into 21 data packages in total, and the split data packages correspond to serial numbers 1 to 21 successively. 
     Optionally, the size of each split data package is determined according to the signs of network entry certification. Specifically, the size of each data package is determined according to the size of the data to be sent, the amount of the signs of network entry certification of the intermediate mobile terminals whose short distance transmission systems are in an idle state, and a transmission rate of a transmission mode applied by a short distance transmission system corresponding to a sign of network entry certification of an intermediate mobile. 
     For example, the theoretic maximum transmission rate of an Enhance Data Rate for Global System for Mobile Communications (GSM) Evolution (EDGE) transmission mode is 384 kbps, the theoretic maximum transmission rate of a Bluetooth Institute of Electrical and Electronics Engineers (IEEE) 802.15 transmission mode is 1 Mbps, and the theoretic maximum transmission rate of a Wi-Fi 802.11g protocol transmission mode is 54 Mbps. It can be learned from the content of the signs of network entry certification that: there are 10 Bluetooth transmission systems in the available short distance transmission systems and there are 10 Wi-Fi transmission systems in the available short distance transmission systems. If the size of the data to be sent is M and the local mobile terminal is a mobile terminal supporting EDGE technology of a GSM system, then the size of data packages numbered 1 to 10, which are transmitted to the Bluetooth transmission systems, is M*1/(54*10+1*10+0.384). Similarly, the size of data packages numbered 11 to 20, which are transmitted to the Wi-Fi transmission systems, is M*54/(54*10+1*10+0.384), and the size of the data package numbered 21, which is transmitted to a base station, is M*0.384/(54*10+1*10+0.384). 
     Step  705 : The local mobile terminal sends the numbered data packages to the local base station and the respective available short distance transmission systems correspondingly, and sends a split message to a base station. 
     Wherein, the split message includes a split coding mode for splitting the data packages, the number of the data packages, the size of the data packages and the serial number corresponding to each data package; and the local mobile terminal supports a Multiple-Input and Multiple-Output (MIMO) transmission mode. 
     For example, the data packages numbered 1 to 10 are respectively sent to the Bluetooth transmission systems in the available short distance transmission systems, the data packages numbered 11 to 20 are respectively sent to the Wi-Fi transmission systems in the available short distance transmission systems, and the data package numbered 21 is sent to the base station. 
     Step  706 : Each available short distance transmission system sends the received data packages to the local base station, and sends a feedback message to the local mobile terminal. The feedback message includes the serial number of the data package and the size of the data package. 
     Step  707 : The local mobile terminal determines, according to the received feedback messages, whether a failure occurs in the transmission of a data package. If a failure occurs in the transmission of a data package, Step  717  is executed. If no failure occurs in the transmission of a data package, Step  708  is executed. 
     Specifically, the local mobile terminal determines, according to the feedback messages received in a preset period of time (5 seconds after the local mobile terminal sends the data packages to the available short distance transmission systems), whether a failure occurs in the transmission of a data package. For example, if the local mobile terminal receives 21 pieces of feedback messages in total within 5 seconds after the local mobile terminal sends the data packages to the available short distance transmission systems, then it is determined that there is no data package transmission failure. If the local mobile terminal receives 20 pieces of feedback messages in total within 5 seconds, then it is determined that a failure occurs in the transmission of a data package. 
     If the number of the feedback messages received by the local mobile terminal within 5 seconds after the local mobile terminal sends data packages transmitted unsuccessfully to the available short distance transmission systems is consistent with the number of the data packages which are transmitted unsuccessfully, then it is determined that there is no data package transmission failure. If the number of the feedback messages received by the local mobile terminal within 5 seconds is not consistent with the number of the data packages which are transmitted unsuccessfully, then it is determined that there is a data transmission failure. 
     Step  708 : The local base station integrates data packages belonging to the same data, and sends the integrated data to a target base station to which a target mobile terminal belongs. 
     Specifically, the local base station performs, according to the split coding mode for splitting the data package in the split message, data decoding and combining to recover data, and transmits, via a communication network, the integrated data to the target base station to which the target mobile terminal belongs. 
     Step  709 : After the target base station receives the integrated data, the target base station sends a request for inquiring states of short distance transmission systems to all relay mobile terminals adjacent to the target mobile terminal. 
     Step  710 : Each relay mobile terminal that has received the request sends a sign of network entry certification to the target base station respectively. 
     Step  711 : The target base station takes a part of short distance transmission systems in an idle state as available short distance transmission systems according to the received signs of network entry certification, and takes the rest of the short distance transmission systems in the idle state as backup short distance transmission systems. If the states of the short distance transmission systems identified by all signs of network entry certification are busy, then the target base station transmits, according to an existing transmission mode, data to the target mobile terminal. 
     Step  712 : The target base station splits, according to the amount of the available short distance transmission systems, the received integrated data into multiple data packages the amount of which is the same as the amount of the available short distance transmission systems, and numbers the data packages. 
     Step  713 : The target base station sends the numbered data packages to respective available short distance transmission systems and the target mobile terminal respectively and sends a split message to the target mobile terminal. 
     Wherein, the split message includes a split coding mode for splitting the data packages, the number of the data packages, the size of the data packages and the serial number corresponding to each data package; and the local mobile terminal supports an MIMO transmission mode. 
     Step  714 : Each available short distance transmission system sends the received data packages to the target mobile terminal, and sends a feedback message to the target base station. 
     Wherein, the feedback message includes the serial number of the data package and the size of the data package. 
     Step  715 : The target base station determines, according to the received feedback messages, whether a failure occurs in the transmission of a data package; when a failure occurs in the transmission of a data package, Step  720  is executed. If no failure occurs in the transmission of a data package, Step  716  is executed. 
     Specifically, the target base station determines, according to the feedback messages received in a preset period of time (5 seconds after the target base station sends the data packages to the available short distance transmission systems), whether a failure occurs in the transmission of a data package. For example, if the target base station receives 21 pieces of feedback messages in total within 5 seconds after the target base station sends the data packages to the available short distance transmission systems, then it is determined that there is no data package transmission failure. If the target base station receives 20 pieces of feedback messages in total within 5 seconds, then it is determined that a failure occurs in the transmission of a data package. 
     If the number of the feedback messages received by the target base station within 5 seconds after the target base station sends data packages transmitted unsuccessfully to the available short distance transmission systems is consistent with the number of the data packages which are transmitted unsuccessfully, then it is determined that there is no data package transmission failure. If the number of the feedback messages received by the target base station is not consistent with the number of the data packages which are transmitted unsuccessfully, then it is determined that there is a data transmission failure. 
     Step  716 : The target mobile terminal integrates the received data packages belonging to the same data, so as to recover the data. The flow is ended. 
     Step  171 : The local mobile terminal determines, according to the received feedback messages, a serial number of a data package which is transmitted unsuccessfully. 
     Step  718 : The local mobile terminal selects, from the backup short distance transmission systems, short distance transmission systems as available short distance transmission systems according to the number of determined serial numbers of data packages which are transmitted unsuccessfully. 
     For example, if the serial numbers of the data packages which are transmitted unsuccessfully are 10 and 11, then a Bluetooth transmission system and a Wi-Fi transmission system are selected from the backup short distance transmission systems as the available short distance transmission systems. 
     Step  719 : The local mobile terminal sends, correspondingly to the available short distance transmission systems, the data packages corresponding to the serial numbers, and Step  706  is executed. 
     Step  720 : The target base station determines the serial number of the data package which is transmitted unsuccessfully, and sends the data package corresponding to the serial number to the target mobile terminal correspondingly, and Step  716  is executed.
