Description

A kind of simple method for testing performance of positioning service system

Technical field

What the present invention relates to is the method for testing of positioning service system (LCS system) performance, the concrete application is to send locating request message to the LCS system by portable terminal, and the LCS system handles locating request message and the Location Request response of receiving is returned to portable terminal with the short message form.

Background technology

The positioning service of LCS system is a mobile communication value-added service.By the cooperation of wireless terminal and wireless network, determine mobile subscriber's actual geographical position, thereby for the service of the information relevant with the position that the user needs is provided.Can be such as the mobile subscriber by this own current position of value-added service inquiry, inquire about the position, position of near restaurant, hospital, bank, restaurant, hotel, government, gas station, cinema or the like, can also inquire about the position at single friend and the present place of a plurality of friends.

Functional requirement according to LCS Client (LCS system client), LCS Client at first is as a platform that provides location-based service to insert, this platform can provide current general access way, comprising: modes such as WAP access, short message access, multimedia message (MMS) access.Simultaneously, LCS Client also needs to carry out information interaction with GMLC (GMLC), so that can finish the location-based service that the user needs, and after LCS Client obtains target location coordinate information from GMLC, also need to GIS server lookup corresponding geographical location information.

GMLC is the kernel entity that the shift position business is provided in the UMTS network.Network provides the access of location service to LCS Client by GMLC, the Location Request that GMLC operation LCS Client sends to certain mobile subscriber, and these requests are transmitted to the MSC of mobile subscriber's current service, after the positional information that this mobile subscriber of acquisition needs, GMLC returns to LCS Client to the result.

GMLC is first node of LCS Client access to mobile network, it obtains targeted customer's routing iinformation from HLR by the Lh interface, then location information request is transmitted to the VMSC (visited mobile switching center) at the current place of targeted customer by Lg interface, and obtains the result of targeted customer position from VMSC.MSC/VLR inserts GMLC by Lg interface, and function comprises operations such as charging, Location Request, mandate and location service.

Current, the test of LCS system there is not the general method of testing of a cover.If adopt real 3G equipment to build LCS system performance testing environment, just need supporting testing equipment: Short Message Service Gateway, SGSN/GGSN, MSC or the like, cost of investment is very high, costs dearly.And adopt test environment of the present invention, and being simple and easy to usefulness, cost is very low.

Summary of the invention

The purpose of this invention is to provide a kind of simple method for testing performance of positioning service system, it has the usefulness of being simple and easy to, the low-down characteristics of cost.

Technical scheme of the present invention is: a kind of simple method for testing performance of positioning service system is characterized in that:

---------simulation GGSN connects simulation MSC---simulation SGSN---GMLC LCS client successively, and LCS client also is connected with the GIS server, builds the performance detection environment of LCS system with the simulation short message gateway;

The simulation short message gateway program at first will send locating request message to LCS Client (LCS client), and both communicate by socket (a kind of communication mechanism of computer network);

LCS client is received after the locating request message that the simulation short message gateway sends, and obtains targeted customer's MSISDN (travelling carriage integrated services digital network) from this message, and sends to GMLC (mobile location centre Chinese gateway);

GMLC is transmitted to mobile subscriber's Location Request the VMSC (Visited Mobile Switching Center) of current service;

After VMSC obtains target location coordinate information from GMLC,, at last geography information is returned to LCS Client in the mode of text also to GIS server lookup corresponding geographical location information;

LCS Client sends it back the simulation short message gateway with the result of Location Request;

The international standard SMPP interface protocol standard (V3.4 version) that adopts between Short Message Service Gateway and the LCS Client, what adopt between LCS Client and the GMLC is the MLP protocol specification, what the interface between GMLC and the MSC adopted is the MAP standard; They all connect by socket.

Principle of the present invention is:

The simulation short message gateway program sends locating request message for LCS Client, and both communicate by socket mechanism.The locating request message that sends can be divided into following several big class:

1, the position enquiring of standard;

2, the position enquiring of Yan Chiing;

3, the position enquiring of cycle triggering;

4, Qu Xiao position enquiring.

Each class inquiry can be divided into different situations again, has 9 kinds of situations, and is as follows:

1, the current position of enquiry mobile terminal;

2, the position of inquiry nearby hospitals;

3, near the position in restaurant the inquiry;

4, near the position in hotel the inquiry;

5, near the position in restaurant the inquiry;

6, near the position of bank the inquiry;

7, near the position of government the inquiry;

8, the current position of the single friend of inquiry;

9, the current position of a plurality of friend friends of inquiry.

After LCS Client receives the locating request message that the simulation short message gateway sends, obtain the MSISDN of target mobile user from this locating request message, and send to GMLC.

GMLC resolves Location Request, checks LCS Client sign and CAMEL-Subscription-Information thereof, derives the MSISDN of target according to LCS Client request or CAMEL-Subscription-Information, takes out the user ID that is positioned, and the client authentication is passed through.GMLC also is to communicate by socket mechanism with simulation GMLC server, and the GMLC server is intercepted port, and the port here gets 7010, and receives the message that sends from GMLC.GMLC is transmitted to the MSC (VMSC) that current mobile terminal is served with locating request message.After obtaining target location coordinate information from GMLC, also need to GIS server lookup corresponding geographical location information, at last geography information is returned to LCS Client in the mode of text, LCS Client sends it back the simulation short message gateway with the locating query result.

The performance test methods of LCS system can carry out the performance test of normal flow.In this case, can the testing standard position enquiring, delay position inquiry, the position enquiring that triggers and the position enquiring of cancellation.

Equally, can also carry out the performance test under the abnormal conditions, such as " the LCS Client that has registered initiates Location Request, but password bad ".

By use simulation short message gateway timed sending message, generate purpose MSISDN at random, the type of getting short message at random waits the performance of testing the LCS system.

At present, to the testing equipment of LCS system seldom, and the equipment that does not have to carry out the LCS system performance test.In order to test the performance of LCS system in the situation that does not have mobile subscriber terminal, Short Message Service Gateway, SGSN and GGSN, use very easy with the LCS system performance testing method of building among the present invention.
