Description
Technical Field
The present invention relates to the field of wireless mobile communication technology, and in particular, to an analog communication system, a deployment method thereof, and an analog communication testing method, and more particularly, to an analog communication system, a deployment method thereof, and an analog communication testing method thereof, in the field of wireless mobile communication technology, in which an analog physical layer is used to support uplink and downlink signaling, data transmission, and multi-user access.
Background
According to 3GPP (3 rd Generation Partnership Project, third Generation partnership project) protocol specification, a control plane and a user plane protocol stack of a 5G (5 th Generation Mobile Communication Technology, fifth generation mobile communication technology) communication system are as shown in FIG. 1, and the control plane protocol stack is a NAS (non-access) layer, an RRC (radio resource control) layer, a PDCP (packet data Convergence) layer, an RLC (radio Link control) layer, an MAC (media Access) layer and a physical layer in sequence from top to bottom; the user plane protocol stack is sequentially an SDAP (service discovery application Specification) layer, a PDCP (packet data Convergence) layer, an RLC (radio Link control) layer, an MAC (media Access) layer and a physical layer from top to bottom; the physical layer is located at the bottom layer of the protocol stack and is responsible for coding and decoding uplink and downlink data, modulating and demodulating and estimating channels.
Under the background of rapid evolution to service and componentization of the communication system nowadays, the development of new functions of a base station and a core network needs to be tested jointly with a terminal, but the conventional joint test of the terminal and the base station is deeply dependent on a protocol stack physical layer and related hardware thereof, and the development speed and the hardware requirement of the protocol stack physical layer (the terminal side physical layer and the base station side physical layer) are difficult to meet the requirement of the joint test, so that the development and the adjustment of the new functions are difficult to advance.
Aiming at the defects, an OAI (open air interface, air interface software alliance) project group is developed to provide an open-source base station and a terminal, the base station and the terminal support pure software data interaction in an analog radio frequency mode, the air interface connection is replaced by establishing a TCP (Transmission Control Protocol ) connection between physical layers of the terminal and the base station, IQ (I path data) data and Q path data generated by physical layers at two ends are directly transmitted through the TCP connection, and therefore data transmission between the terminal and the base station under the condition of no physical layer equipment is completed. It still has associated data operations of the physical layer and the MAC (media access) layer is coupled with the physical layer severely, resulting in that the software-based access method it employs is difficult to migrate to other communication systems and only supports analog single user access. The multi-terminal simulator is provided by instrument manufacturers such as De-tech and instrument manufacturers and can support simultaneous access of multiple users, but the multi-terminal simulator requires a base station to have complete physical layer and physical layer device support, so that the multi-terminal simulator is limited by the physical layer to a certain extent, and the purchase of a large number of terminal simulation instruments can bring about rapid rise of cost. Chinese patent application CN102421112a proposes a mobile terminal simulator comprising a mobile terminal protocol stack and a simulated physical layer, a simulated RLC (Radio Link Control ) module and a simulated MAC module; the mobile terminal simulator is mainly used for carrying out simulation test of the base station function by matching with a designed simulation system, and testing the protocol stack of the terminal by intercepting the messages of the MAC layer and the RLC layer of the real terminal. Because the simulated physical layer, the simulated MAC module and the simulated RLC module can only receive the message and verify the correctness of the message, and cannot support uplink signaling and data transmission, the method can only test whether the operation of the protocol stack of the mobile terminal is normal, and cannot coordinate with the reply of corresponding signaling to carry out uplink related function adjustment and measurement of the base station protocol stack; and the simulation terminal can not simulate multi-user access, and can not help the base station protocol stack and the network to perform multi-user related function test.
Although the joint test of the terminal and the base station in the proposal provided by the prior art does not depend on the physical layer and related devices deeply, the physical layer design in the proposal still has the problems of serious coupling with the MAC (media access) layer, dependence on physical layer hardware equipment, no support of uplink signaling, data transmission, multi-user access and the like, thereby being not beneficial to the research and development and the adjustment of new functions of the base station and the core network.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail by means of specific examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Firstly, the technical idea and thought of the present invention are introduced, as mentioned in the background art, the physical layer design in the scheme proposed in the prior art still has the problems of serious coupling with the MAC (media access) layer, dependence on hardware equipment, no support of uplink signaling and data transmission, multiuser access, etc., thus being unfavorable for the research and development and adjustment of new functions of the base station and the core network.
In order to solve the above problems, the inventors found through researches that, since the physical layer provides the physical layer data processing and transmitting functions for the higher layer protocol stack, and the higher layer data processing and the lower layer data processing and transmitting are located at different levels, the lower layer protocol stack only provides a functional interface for the upper layer protocol stack, so that only the physical layer needs to be replaced by an analog physical layer capable of simulating data transceiving, and the physical layer data processing operations such as modulation and channel coding of the physical layer are not performed, and the message field is directly transmitted, so that the user access and data transceiving functions can be realized, and meanwhile, the limitation of physical layer equipment can be eliminated. Based on the above, the invention provides an analog communication system which adopts an analog physical layer to support uplink and downlink signaling, data transmission and multi-user access. In the scheme of the invention, the terminal side protocol stack and the base station side protocol stack both adopt the simulated physical layer capable of simulating data receiving and transmitting, wherein the simulated physical layer directly transmits the message field and does not carry out physical layer data operations such as physical layer modulation, channel coding and the like, thereby being capable of realizing better communication simulation without depending on physical hardware. Based on the improvement, the invention provides a simulated communication system which is used for simulating a data communication process between a terminal and a base station, the simulated communication system comprises a simulated terminal and a simulated base station, wherein the simulated terminal comprises a terminal side simulated physical layer supporting data transmission and function verification with the base station, the simulated base station comprises a base station side simulated physical layer supporting data transmission and function verification with the terminal, and a simulated channel for transmitting data is arranged between the terminal side simulated physical layer and the base station side simulated physical layer.
For a better understanding of the present invention, reference will now be made in detail to the drawings and examples.

It should be noted that, the terminal side higher layer protocol stack sequentially includes, from top to bottom, a NAS (non-access) layer, an RRC (radio resource control) layer, an SDAP (service discovery application specification) layer, a PDCP (packet data convergence) layer, an RLC (radio link control) layer, and an MAC (media access) layer, and MAC-PHY interface communication is adopted between the terminal side higher layer protocol stack and the terminal side analog physical layer; the base station side high-layer protocol stack sequentially comprises an RRC (radio resource control) layer, an SDAP (service discovery application Specification) layer, a PDCP (packet data Convergence) layer, an RLC (radio Link control) layer and an MAC (media Access) layer from top to bottom, and MAC-PHY interface communication is adopted between the base station side high-layer protocol stack and the base station side analog physical layer. It should be noted that, communication between the terminal side high-level protocol stack and the base station side high-level protocol stack, and the MAC-PHY interface are conventional in the art, and the present invention is not specifically described, and in the embodiment of the present invention, the working principles of the terminal side analog physical layer, the base station side analog physical layer, and the analog channel are mainly described.
Further, in order to better understand the present invention, a flow of processing uplink data and downlink data in the analog communication system will be briefly described by taking fig. 2 as an example, where the uplink data is data sent by the analog terminal to the analog base station, and the downlink data is data sent by the analog base station to the analog terminal. For upstream data: the simulation terminal obtains application data from a user, after processing of an SDAP (Service Discovery Application Profile, service discovery application specification) layer, a PDCP (Packet Data Convergence Protocol ) layer, an RLC layer and an MAC layer, the application data is put into an MAC-PHY interface of the simulation terminal, then a terminal side simulation physical layer obtains the data from the MAC-PHY interface of the simulation terminal, the data is put into a predefined simulation channel, and then the simulation channel sends the data to a base station side simulation physical layer; the base station side simulation physical layer analyzes the received data packet, then the analyzed data is put into an MAC-PHY interface of the base station side, then the base station side MAC layer acquires the data and processes the data according to a base station side protocol processing flow, and the data is sent to a core network through GTPU (GPRS Tunneling Protocol ), so that the data packet exchange of the terminal user is completed. For downstream data: the base station side simulation physical layer acquires data from the MAC-PHY interface of the base station side, packages the data into a downlink data packet, and then sends the data packet to the terminal side simulation physical layer through a simulation channel; after receiving the data packet, the terminal side simulation physical layer analyzes the data packet and sends the analyzed data to the application layer
