The design of data exchange interface see the digital 6, wherein each to interior of the invention, arranged between each of which is defined a series of data exchange interface, thus to realize the black box comprises laid the base. The so-called black testing box of both of between the analogue module and wireless internet of each other unknown, wherein the data exchange between each module is conducted by a data interface, in which the no need to understand of each other design method, only need to associate with a and data exchange protocol and data format; and with an adhesive the meets the analogue B3G test software. Simulation traditional software a data exchange interface in each module, when the network simulating layer; the MT and AND in the containing, and further arranged on the unceasing exchange, how a data interface and corresponding module and a complex. The invention is formed on to the interior of each submodule definition data exchange interface, wherein a solved the problem. The is of data exchange interface sees attached digital 3, A1 interface, A2, B3 and B4 belong to the AP, a B1, B2, A3 and A4 belong to the MT a, the interface is defined the same to a data exchange protocol and format. A1, A2, A3 and A4 interface is provided with a downlink (from AND a communication of MT), downlink data packet interface (A1 for and reactive talk transmit-receive module the buffer AND service generating module and service AND production generating module, interface A2 the buffer transmitter is a downlink data frame for transmitting, unequal the processing of wireless environment, and data frame after treatment and reactive MT talk transceiver and A3 interface exchanges the data interface, A4 is used for cache from the demodulation receiver decoding a data packet is connected to the same, and a to the MT counting module and integral condition counting function executing the performance statistics function. B1, B2, B3 and B4 are useful in uplink (MT to the communication of) AND corresponding data exchange. As the data buffer with a concave table (A1, A4 B1, and B4, and a a series of concave table operation function for example: Add () is added data packet, Delete () to delete part concave table element), (Space (release concave table space) filled on the operation to the data interface in concave table tail). Is fixed to array A2, A3 B2, and B3 and data exchange device. Wherein the data exchange definitions interface when to flow, by a limited by multiple objects, wherein the object in the same data exchange interface, wherein the cooling system with multiple module, corresponding interface is problem.

Further claims a simulation to the analogue invention of distributed cell structure to the distributive cell, and is structure of distributed cell see digital 7 and 8 shape, the method according the invention claims an are symmetrically arranged 4 antenna array (is calling remote antenna unit), the antenna array is arranged in the cell centre the distance is 667m. The antenna array is divided into a cell 9 areas; and shown the digital 5, wherein MT is an area 2, 4, 6 and 8:00, AND the controller is a corresponding to the area remote antenna unit and corresponding; And when MT is an area 1, 3, 7 and 9:00, AND the control of said two adjacent regions RA1 and corresponding; The MT is in of 5:00, AND then controlling the MT and corresponding. On the position of the invention has testing platform virtual geographic information and current terminal, a use distributive cell structure of a feedback loop realizing teeth. Rigid to the preceding message for distributed cell structure is one of our outdoor B3G system key technologies, a terminal is downward selecting is steps recent RA1 end of the communication with a to save resources. The testing platform according to the invention board, we a base, matched with the virtual plane map, first determining reference zero points, wherein both the cell (key monitoring cell) the centre of the horizontal is a socket; the platform everything according to the position and entity automatically according to the reference socket, determining for are corresponding position data (x, y), and location information recording the related object; the position RA1 according to any MT position and AND position and AND connected. The testing platform; AND each to an with a connecting RA1 position information. Pats the end of each series, the tstep of wherein the preceding message teeth, MT first according to the mobile diameter and speed calculation for new position; and feeding back of the uplink comprising a RA1 position information of corresponding AP, AND a shaft according to oneself to recording, wherein the equal MT and are RA1 distance, and is fixed with the MT is steps recent RA1 end of the communication with the MT and later the antenna unit, is the MT closing to the nearer RA1 of. The spacer, wherein the MT performance of two, AND can further control at the same time of RA1 and MT housing, wherein a space diversity, improving performance system. The method using end of the communication RA1 with MT to form of a MT mobile unceasingly, wherein of improving performance system.
