technical field

The invention relates to the field of communication testing, in particular to a system and method for testing a mobile positioning system.

Background technique

With the continuous development of telecommunication services, mobile users are increasingly dissatisfied with simple voice call services, and require the system to provide various value-added services such as banking services, securities transactions, E-mail sending and receiving, MMS, and mobile positioning. In order to improve service quality, attract users, and then be invincible in the fierce market competition, network operators must constantly introduce new types of services. The mobile positioning service is used to meet the needs of operators and mobile users. With the launch of the mobile positioning service, the increasing number of mobile users will inevitably put forward higher requirements for the stability and processing capacity of the mobile positioning system. Therefore, how to better test the stability and processing capability of the mobile positioning system is particularly important.

In the process of performing a complete location request service, MS (MobileStation, mobile station), BSS (Base Station System, base station system), PDSS (PacketData Service Sytem, packet data service system), MSC/VLR/HLR ( MSC: MobileSwitching Center, mobile switching center; VLR: Visitor Location Register, visiting location register; HLR: Home Location Register, home location register), MC (Message Center, short message center), MPC (Mobile Position Center, mobile positioning center) As well as multiple sets of network equipment such as PDE (Positon Determination Entity, positioning entity), as long as there is a problem in one of the links, the entire test cannot be carried out, which seriously affects the test efficiency. In addition, the location request message initiated by the mobile station or the location service client (LCSClient: LocationServer Client location service client) is relatively simple, and each time it is sent, it is the same kind of message, and various parameters cannot be adjusted, and the system cannot be well implemented. The tests of various abnormal conditions fail to achieve the purpose of various abnormal tests. Moreover, the number of test mobile stations is limited, at least two or three, and the system cannot be tested for large traffic, and the requirements for testing the processing capability of the mobile positioning system cannot be met. In addition, the types of messages initiated by the mobile station cannot be flexibly adjusted, and messages cannot be sent according to different proportions of various types of messages. Due to the limitations of the above-mentioned various conditions, the existing test environment cannot conduct real and effective stability and performance tests on the mobile positioning system. It must be done. With this technology, the above-mentioned problems can be solved and work efficiency can be greatly improved.

Detailed ways

A system and method for simulating and requesting location information according to the present invention mainly adopts a modular structure technology, and each module is logically independent and functionally interrelated. The system can also carry out function expansion and function transplantation on the basis of this modularization.

The implementation of the simulation request location information system of the present invention will be described in detail below in conjunction with the accompanying drawings.

Fig. 1 is a network structure diagram of a simulation request location information system and method according to the present invention, wherein the simulation request location information system includes: a system under test 1, a simulation system 2, a simulated object 3, and a No. 7 signaling network 4. TCP/IP network5. Due to limited space, this figure only draws the network entities involved in the simplest location information request, and combines the simulated objects BSS/MSC/VLR/HLR/PDSS/LCSClient/MS into one schematic diagram. From the figure, we know , the simulation system described in this invention replaces equipment such as BSS/MSC/VLR/HLR/PDSS/LCSClient/MS, and directly requests position information from the measured object positioning system (MPC&&PDE) by simulating various real situations.

The simulation system is physically composed of two entities, one is a simplified machine connected to No. The processors share a simple machine, which can be set differently according to conditions and test requirements, and it is very flexible to use. For example, it is necessary to perform a performance test on the positioning system, and to test the ability of the positioning system to process short messages per second. At this time, it is necessary to consider setting up the multi-service processor of the simulation system; if it is an abnormal test under certain conditions, only one service processing is required. Only one machine is enough, so that the equipment can be reduced and the test cost can be saved.

FIG. 2 is a block diagram of a system and method for simulating requesting location information according to the present invention. Among them, F represents an important interface in the system, and G represents support. It can be seen from the figure that the present invention consists of five major parts: a human-computer interaction module 21 , a service processing module 22 , a standard communication module 23 , a signaling gateway module 24 and an operation support module 25 . The human-computer interaction module 21 mainly completes various data input and output of the system, and provides data to the standard communication module 23 and business processing module 22 through relevant interfaces to complete various business functions of the simulation system. The business processing module 22 mainly completes business process control, encodes and decodes various messages, and manages system resources. The business processing module 22 is the main processing system of the system. The standard communication module 23 is used to complete the message interaction between the system and the TCP/IP network and message interaction with other modules. The signaling gateway module 24 mainly completes the No. 7 signaling message forwarding function. In addition, the signaling gateway module 24 completes the multi-module message distribution function to realize the support of the multi-module function in this system. The operation support module 25 is a support platform for other modules to operate. The operation support module 25 is used as a message transmission channel to send the message from the signaling gateway module 24 to the service processing module 22, and simultaneously send the message from the service processing module 22 to the signaling module. Make the gateway module 24.

The human-computer interaction module 21, business processing module 22, standard communication module 23, signaling gateway module 24, and operation support module 25 of this simulation system are logically independent and independent of each other, but functionally related and closely linked. The five parts are logically independent, and this design strengthens the modularity, which is conducive to maintenance and error checking, and is also conducive to software transplantation.

Fig. 3 is a program flow chart of a method for simulating requesting location information according to the present invention. The process is as follows:

301 System initialization, including reading communication configuration files, completing global variable initialization, clock initialization, and process initialization;

302 Establish a communication channel with the mobile positioning system (Signaling No. 7 link and TCP/IP link);

303 Message processing and sending of the business processing module;

304 Sending messages of the running support module;

305 Message sending by the signaling gateway module;

306 Message sending of standard communication module.

The program flow of the system will be introduced in detail below in conjunction with FIG. 3 .

The system starts up and performs system initialization. This process is mainly to read the communication configuration file, complete global variable initialization, clock initialization, process initialization, and then establish a communication channel with the mobile positioning system (Signaling 7 link and TCP/ IP link). If the process fails, the system will automatically exit and restart the system. Otherwise, the system enters the task-ready state, and the business processing module 22 and the human-computer interaction module 21 are also in the work-ready state.

The triggering of the system message can be realized through the human-computer interaction module 21. After changing the parameters through the human-computer interaction module 21 and issuing the command, the business processing module 22 reads the parameters set by the human-computer interaction module 21 and encodes them to construct the message that needs to be sent. message, send the message to the standard communication module 23.

The triggering of the system message can also be realized through the timer task, the timer is set in the human-computer interaction module 21, and different time intervals can be set, and different timers can also be set according to different messages. After the timer expires, the business message processing is similar to the message processing triggered by the man-machine command. It also reads the set parameters and encodes them to construct the message to be sent, and sends the message to the standard communication module 23 .

After the standard communication module 23 receives the message sent by the business processing module 22, it does not process the message, and directly utilizes the established communication channel to transmit the message to the mobile positioning system through the TCP/IP protocol, and the operation support module 25 processes the same. The message received from the service processing module 22 is directly sent to the signaling gateway module 24, and the signaling gateway module 24 does not process it, and directly transmits it transparently, and uses the established communication channel to transmit it to the mobile positioning system through the No. 7 protocol.

It is this kind of mutual independence and mutual coordination among the modules that makes the configuration of the system flexible and It has the advantages of powerful functions and strong portability.

The message sent, and then the message is sent to the standard communication module 23.

After receiving the message, the standard communication module 23 does not process the message, but directly transmits it to the mobile positioning system through the pre-established TCP/IP communication channel.

After receiving the message initiated by the mobile terminal of the simulation system, the mobile positioning system performs its own business processing, and finally returns the position information result to the simulation system, and the simulation system displays the result through the human-computer interaction module 21 .

First, the standard communication module 23 of the simulation system receives the message, and the standard communication module 23 sends the received message to the business processing module 22 .
