Detailed ways

FIG. 1A is a schematic structural diagram of a wireless network simulation system in the prior art. As shown in FIG. 1A , the wireless network simulation system in the prior art includes several propagation model modules and a database module. When using this system to simulate a wireless network, it is necessary to call a certain propagation model module, that is, to select the propagation model used for simulation. The propagation model module obtains parameter information required for simulation from the database module, and performs calculation and simulation on the wireless network according to the propagation model saved by itself and the obtained parameter information.

Since both the communication model module and the database module can be provided by a third party, the interface protocols adopted by different third parties are also different, so the interface protocols of each communication model module and database module are not standardized and universal, so the communication model When the module and the database module interact, a dedicated communication entity needs to convert the information exchanged between the propagation model module and the database module through protocol conversion for communication, as shown in FIG. 1B . Fig. 1B is a schematic diagram of the specific implementation structure of the wireless network simulation system in the prior art. In Fig. 1B, the wireless network simulation system includes propagation model modules a and b, and database module A. Since the interface protocols of these three modules are different, Therefore, when communication model modules a and b interact with database module A, corresponding communication model agent entities need to be established for communication. As shown in Figure 1B, when the communication model module a interacts with the database module A, the established communication model proxy entity aA needs to perform protocol conversion between the communication model module a and the database module A, so that the communication model module a can obtain The parameter information in the database module A, when the communication model module b interacts with the database module A, it is necessary to perform protocol conversion between the communication model module b and the database module A through the established communication model proxy entity bA, so that the communication model module b Obtain the parameter information in database module A.

It can be seen from FIG. 1B that in the existing wireless network simulation system, a propagation model proxy entity needs to be established for each propagation model module, which increases the complexity of the wireless network simulation system and reduces the efficiency of wireless network simulation.

In the embodiment of the present invention, in order to reduce the complexity of the wireless network simulation system, a parameter information forwarding device for wireless network simulation is added between the propagation model module and the database module, and the parameter information forwarding device for wireless network simulation is obtained in the database module parameter information, and encapsulate the obtained parameter information into information in a common format and send it to the propagation model module. No matter what interface protocol the propagation model module adopts, it can recognize the information in the general format and decapsulate it to obtain parameter information. Therefore, there is no need to establish a propagation model proxy entity for each propagation model module, which reduces the complexity of the wireless network simulation system and improves the efficiency of wireless network simulation.

Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

FIG. 2 is a parameter information forwarding process of wireless network simulation provided by an embodiment of the present invention, which specifically includes the following steps:

S201: Obtain parameter information in a database module.

In the embodiment of the present invention, a parameter information forwarding device for wireless network simulation is added between the propagation model module and the database module in the wireless network simulation system. The parameter information forwarding device for wireless network simulation can also be called middleware, as follows The middleware is the parameter information forwarding device of the wireless network simulation.

The middleware is connected with each propagation model module and database module. When performing wireless network simulation, the middleware acquires parameter information in the database module. Wherein, the user may send an instruction to the middleware as required, to instruct the middleware to acquire specified parameter information in the database module. The parameter information includes: base station parameter information, cell parameter information, geographical parameter information, antenna parameter information, wireless environment parameter information and other parameter information required for simulation.

S202: Encapsulate the obtained parameter information into information in a set general format.

Among them, the general format of the setting includes the Extensible Markup Language (XML) format. Since XML is a common language for data exchange, the propagation model module can recognize the XML format regardless of the interface protocol adopted by the propagation model module. information to get parameter information. Of course, the set common format may also include other common formats, as long as the propagation model module adopts a format that can be recognized by any interface protocol.

S203: Send the encapsulated information of the set general format to the propagation model module selected from the plurality of propagation model modules.

In the embodiment of the present invention, when the user performs wireless network simulation, he can select the identification information of at least one propagation model to be used, and the middleware can use the identification information of at least one propagation model module selected by the user to package the device Send information in a predetermined common format to at least one selected propagation model module.

In the above process, the middleware obtains the parameter information in the database module, and encapsulates the obtained parameter information into information in a set general format and sends it to at least one propagation model module. Since the middleware obtains the parameter information in the database module in the embodiment of the present invention, and encapsulates the parameter information into information in a general format and sends it to the propagation model module, no matter which interface protocol the propagation model module adopts, the information in the general format can be Information decapsulation to obtain parameter information, without the need to establish a corresponding propagation model proxy entity for each propagation model module in the wireless network simulation system for protocol conversion, which reduces the complexity of the wireless network simulation system and improves Improve the efficiency of wireless network simulation.

In the embodiment of the present invention, the specific process for the middleware to obtain parameter information in the database module is that the middleware sends an acquisition request for obtaining parameter information to the database module through the interface protocol of the database module, and receives the returned response from the database module. The parameter information encapsulated by the interface protocol. Wherein, the middleware supports the interface protocol of the database module.

Since the parameter information returned by the database module is the parameter information encapsulated by the interface protocol of the database module, when the middleware encapsulates the parameter information into the information of the set general format, the parameter information encapsulated by the interface protocol should be processed. Decapsulate, and encapsulate the decapsulated parameter information into information in the general format of the setting. Among them, the middleware can invoke the set protocol template, decapsulate the interface protocol of the database module, and encapsulate the decapsulated parameter information into the set general format information. When the general format of the setting is XML format, the protocol template can be saved in a file in XML Schemas Definition (XSD) format.

In the embodiment of the present invention, it is considered that some propagation model modules in the wireless network simulation system may malfunction and cause failure, and the failed propagation model modules must not be able to accurately simulate the wireless network. Therefore, for at least one propagation model module, before the middleware sends the encapsulated information of the set general format to the propagation model module, it also needs to determine that the propagation model module is in the middle according to the registration information of the propagation model module saved by itself. has been registered in the software, that is, the middleware determines that the propagation model module is an available propagation model module. Wherein, when the wireless network simulation system is started, each available propagation model module in the wireless network simulation system sends the registration information of the propagation model modules to the middleware, and the middleware saves the registration information of these propagation model modules, indicating that sending these propagation model module registration information The information dissemination model module is available.

After the middleware sends the encapsulated information in the general format of the setting to the propagation model module, the propagation model module can decapsulate the information in the general format of the setting, obtain parameter information, and simulate the wireless network according to the parameter information . Take the set general format as XML format as an example. After the propagation model module receives the information in the XML format, it decapsulates the information in the XML format, obtains the parameter information, and based on the propagation model and parameter information saved by itself , to simulate the wireless network.

In the embodiment of the present invention, after the propagation model module simulates the wireless network according to the parameter information, it also returns the simulation result to the middleware, and the middleware receives the simulation result returned by at least one propagation model module, and encapsulates the simulation result The data in the set general format is sent to the database module for storage. Wherein, the middleware supports the interface protocols of each propagation model module.

That is to say, the middleware encapsulates the parameter information sent by the database module to the propagation model module, and the simulation results returned by the propagation model module to the database module into information in the set general format, so that each propagation with different interface protocols The model module and the database module can uniformly encapsulate the sent information into a set general format through the middleware to realize information interaction, reduce the complexity of the wireless network simulation system, and improve the efficiency of wireless network simulation.

In the embodiment of the present invention, it is considered that in the process of simulating the wireless network according to the parameter information of each propagation model module, there may be abnormal situations that may lead to inaccurate simulation results. These abnormal situations include: the operation of the propagation model module is unexpected Interruption, insufficient resources required for operation, etc. Therefore, for at least one propagation model module, the middleware monitors whether the propagation model module is abnormal during the process of simulating the wireless network according to the reference information, and instructs the propagation model module to terminate the simulation when an abnormality is detected. , that is, terminate the process of simulating the wireless network using the propagation model module, and output an error report.

Fig. 3 is the detailed process of the wireless network emulation that the embodiment of the present invention provides, specifically comprises the following steps:

S301: The middleware sends an acquisition request for acquiring parameter information to the database module through an interface protocol of the database module.

S302: Receive the parameter information encapsulated by the interface protocol returned by the database module.

S303: The middleware decapsulates the parameter information encapsulated by the interface protocol, and encapsulates the decapsulated parameter information into information in XML format.

S304: For at least one selected propagation model module, the middleware judges whether the propagation model module has been registered in the middleware according to the registration information of the propagation model module saved by itself, if the judgment result is yes, proceed to step S305, otherwise proceed to Step S308.

S305: Send the encapsulated information in XML format to the propagation model module.

S306: The propagation model module decapsulates the information in XML format, acquires parameter information, simulates the wireless network according to the parameter information, and returns the simulation result to the middleware.

S307: The middleware receives the simulation result returned by the propagation model module, encapsulates the simulation result into data in XML format, and sends it to the database module for storage.

S308: It is determined that the propagation model module is unavailable, and the information in the XML format is not sent to the propagation model module.

Wherein, the middleware can also monitor whether the propagation model module is abnormal during the process of the propagation model module simulating the wireless network according to the parameter information, and if abnormality occurs, instruct the propagation model module to terminate the simulation and output an error report.
