And on the basis, modifying the base station broadcast parameters and interactive contents communicated with the 3G terminal according to a 3GPP protocol, completing connection and disconnection with the mobile terminal, and extracting the identity information of the mobile terminal user. Meanwhile, the control reselection access command generating unit 12 generates a handover signal to maximally assist the wireless signal access unit 11 in sensing the mobile terminal. The specific implementation mode comprises the following steps:
data transfer processing process 131: the USB2.0 communication protocol is realized, and the digital signal is transmitted and received with the wireless signal access unit 11. And further completes the modulation and demodulation and error correction coding and decoding of the digital signal by utilizing the computing resources of the equipment. When data is sent, 3GPP protocol data to be sent is modulated, coded and converted into digital signals, and the digital signals are sent through a USB 2.0; when receiving data, the digital signal received by the USB2.0 is demodulated, corrected and decoded to recover 3GPP protocol data.
The protocol data processing process 132: the standard protocol of the wireless communication network based on the open source software can be divided into three layers, namely a physical transmission layer, a data link layer and a network layer. Wherein the physical layer is used to provide a physical link over which the bitstream is transmitted. The data link layer establishes a reliable dedicated data link required for communication of messages between the systems of the wireless communication network. The network layer is an entity for transceiving and processing signaling messages, and the function is most important. The network layer is divided into a radio resource management layer, a mobility management layer and a connection management layer. The radio resource management layer establishes a data transmission path and a signaling path for the mobile terminal. The mobility management layer processes location information of the mobile terminal. The connection management layer handles the routing function. In addition to completing the basic protocol contents of the wireless communication network, the signal strength of the wireless signal access unit 11 is the strongest in the coverage area thereof by modifying the parameters of the radio resource management layer, so that the mobile terminal is easier to perform cell reselection. And extracting the identity information of the mobile terminal user while reselecting the cell with the mobile terminal, wherein the identity information comprises a mobile user identification code and a mobile equipment identity code.
The following is a flow for explaining the protocol data processing process 132 extracting the mobile terminal identity information in the mobile terminal cell reselection process according to the present invention. The protocol data processing process 132 constructs new system information, and broadcasts and transmits the new system information through the wireless signal access unit 11; after receiving the broadcasted system information, the mobile terminal initiates a cell reselection process according to a cell reselection strategy, sends an Access request in a Random Access Channel (RACH), and applies for a Stand-Alone Dedicated Control Channel (SDCCH); the protocol data processing process 132 responds to the access request by granting access to the channel on the downlink channel. Sending SDCCH channel allocation information to the mobile terminal on the AGCH channel, in other words, the AGCH is used for the equipment to send the assigned independent dedicated control channel SDCCH to the mobile terminal with successful random access; the mobile terminal accesses the distributed SDCCH channel and sends a LOCATION UPDATE REQUEST message to REQUEST LOCATION updating; the protocol data processing process 132 constructs an IDENTITY identification REQUEST message requesting the IDENTITY information of the mobile terminal, including the mobile subscriber IDENTITY and the mobile equipment IDENTITY; the mobile terminal responds to the identity request and returns the identity information of the mobile terminal; the protocol data processing process 132 constructs a LOCATION UPDATE ACCEPT message to allow access by the mobile terminal.
The switching signal configuration process 133: for controlling the generation of the appropriate switching signal. The 3G protocol modifies the wireless communication network protocol in the aspect of base station identity authentication, the wireless communication network protocol does not perform identity authentication on the base station when the mobile terminal accesses the base station, and the 3G protocol realizes identity authentication on the base station when the mobile terminal accesses the base station. Since the wireless signal access unit 11 does not establish communication with the mobile communication service provider and cannot pass the base station identity authentication of the mobile terminal, the function of the handover signal is to make the mobile terminal reselect the wireless signal access unit 11 in a manner described in the wireless communication network protocol. The cell reselection process of the mobile terminal comprises the following steps: the mobile terminal always measures the signal quality of the cell and surrounding cells, sorts the signal quality, and selects a cell capable of providing the optimal service quality. The handover signal allocation process 133 dynamically affects the signal quality of the base station according to the signal quality of the cell near the location of the wireless signal access unit 11, so that the base station is not enough to provide a stable mobile communication service for the mobile terminal. The mobile terminal in turn reselects to a wireless communication network base station for more stable communication services. Since the wireless signal access unit 11 performs the basic functions of a base station of a wireless communication network under the control of the protocol data processing process 132 and provides better signal quality, the mobile terminal reselects to the wireless signal access unit 11, and the mobile terminal ignores the identity authentication of the base station during the reselection.
And (3) user identity extraction process: the method is used for extracting and summarizing the user identity information of the mobile terminal and mainly comprises the mobile user identification code of the mobile terminal user. The mobile subscriber identity may be requested from the mobile terminal when the mobile terminal reselects to the wireless signal access unit 11, and then the mobile subscriber identity of the user is extracted from the protocol contents processed by the protocol data processing process 132 by the user identity extraction process. And after the mobile user identification code corresponding to the mobile terminal user is extracted, the mobile user identification code is stored into the database module by the user identity extraction process.
The database module work flow realizes writing and reading the identity information of the mobile terminal user. The database module comprises a data storage process and a data storage space, is used for conveniently storing and reading the identity information of the mobile terminal user, and mainly comprises a mobile user identification code of the mobile terminal user and a mobile equipment identity code of the mobile terminal.
And (3) data access process: communicating with the signal processing unit 13 to obtain the identity information of the mobile terminal to be stored into the data storage space or to read the identity information of the user of the mobile terminal from the data storage space.
Data storage space: and storing the identity information of the mobile terminal in a mobile user identification code and mobile equipment identity code format.
