Abstract

The invention discloses a method for testing a core network data traffic performance through signaling simulation, belonging to the technical field of communication. The method provided by the invention comprises the steps of: a, in a core network grouping domain, initiating a data traffic request to a core network in a signaling simulation manner; b, simulating authentication, encryption and PDP (Packet Data Protocol) activation processes of access of a core network interface to obtain an IP and a DNS (Domain Name System) using 3G network data traffic; c, simulating an actual user to use various data traffics in the network by using the IP and the DNS; and d, obtaining the performance of core network transmission and service quality of data traffic according to the steps b and c. The method disclosed by the invention can be used in a GPRS (General Packet Radio Service) and a 3G (including TD (time division) and UMTS(Universal Mobile Telecommunications System)) networks, and used for testing the performance of the core network data traffic in the signaling simulation manner.

Description

A kind of method of the core network data service feature being tested through signaling emulation

Technical field

The present invention relates to GPRS and 3G network, relate in particular to method in Gb or IuPS interface testing data service performance.Belong to communication technical field.

Background technology

Data service has obtained increasing system operator and value-added service merchant's attention as the important service form of communication network.Yet when convenient communication service being provided, also because its content of mobile data services and the complexity of flow process, the diversity of PS domain core net network interface make its network and service availability real time implementation monitoring and diagnosis difficulty increase greatly for the user.In order to monitor all kinds of availability of traffics in real time, to detect service quality, do not receive wireless environment to influence the operational trials system of modelling customer behavior, periodicity testing network element and service availability but just need to make up a cover.Existing conventional PS territory obstacle means of testing mainly contains: terminal module service dial testing, the mutual Ping Test of network element, network element are sent out three kinds of modes such as Test Message mutually.Because all are thanksed for your hospitality to general service, the professional perception of the whole network detects and implement that difficulty is big, test result exists the interfere information analysis also to need deficiencies such as artificial intervention to have test period; Application scenarios is limited to some extent, need be replenished perfect during network monitoring is put into practice with maintenance by the testing mobile data service system.Testing mobile data service of the present invention system be insert at core network interface, to initiate testing with the signaling emulation mode to each network element and SP server professional, thereby the periodicity that realizes indexs such as professional available situation, network element load-carrying properties, route smoothness, the professional perception of new generation online operational trials system of test automatically.Through the introducing of testing mobile data service system, can further promote the ability of finding prior to the user, promote the O&M supporting effect.

Summary of the invention

All are thanksed for your hospitality to general service, the professional perception of the whole network detects and implement the problem that difficulty is big, there is interfere information in test result to the objective of the invention is to solve the test period that exists in the prior art, and a kind of method of brand-new PS domain data service test is provided.

Compare with prior art, this method has the unperturbed test, can detect strong, the concentrated characteristics of being convenient to manage of disposing of the professional perception of the whole network, business and network element obstruction forewarning ability.This method is applicable to the data service core net of networks such as GPRS/UMTS/TDSCDMA.

Specifically, the inventive method comprises:

A) when emulation testing, simulator is initiated data service request with the mode of signaling emulation to GPRS serving GPRS support node SGSN (ServiceGPRS Support Node);

Simulator can be supported two types network, comprises GPRS and 3G (UMTS and TD-SCDMA).In the GPRS core net, simulator simulation packet control unit PCU (Packet Control Unit) initiates data service request through Gb Interface to core net; In the 3G core net, simulator analog wireless networks controller (RNC) (Radio NetworkController) is initiated data service request through the IuPS interface to core net.

B) authentication, encryption and PDP (the Packet Data Protocol) activation process that inserts of emulation core network interface obtains using the IP and the DNS of 3G network data service.

C) utilize IP and DNS simulates real real user to use various data services in the network.

D) according to step b, c, draw the performance of core net transmission network and the service quality of data service.

Good effect of the present invention is:

Insert, initiate the testing business to each network element and SP server through core network interface, thereby the periodicity that realizes indexs such as professional available situation, network element load-carrying properties, route smoothness, professional perception is tested automatically with the signaling emulation mode.The present invention compares with conventional art, but is that a cover does not receive wireless environment to influence the operational trials system of modelling customer behavior, periodicity testing network element and service availability.

Embodiment

Combine accompanying drawing that the present invention is described further through specific embodiment below.

Fig. 1 representes the network topological diagram of the 3G network (comprising UMTS and TD-SCDMA) of the embodiment of the invention; As shown in Figure 1; RNC is connected with SGSN through the IuPS interface, and the latter is connected with GGSN through gn interface, and GGSN is connected with PDN through the Gi interface simultaneously; SGSN links to each other with the RNC simulator through the IuPS interface in addition, and the RNC simulator is connected with Analysis server.

But in order to realize not receiving wireless environment to influence the target of modelling customer behavior; The RNC simulator uses real mobile phone logo IMSI (International Mobile Subscriber Identity); Simulation and realize all protocol signalings of IuPS interface comprises that the user adheres to (Attach), separates (Detach), authentication (Authtication), (Inter-SGSN RAupdate) upgraded in the position, PDP activates (Active PDP Context) and PDP deexcitation Signalling exchange flow processs such as (Deacitve PDP Context).The RNC simulator obtains the IP and the DNS information of data service face through the emulation of signaling surface protocol and flow process, utilizes IP and DNS analogue simulation user behavior again, the performance of testing various data services.Upload and download, receiving and dispatching mail etc. comprising common data service GPRS online, WAP online, multimedia message transmitting and receiving service, FTP service, also comprise GPRS data service mobile phone QQ, MSN, Fetion etc. end to end simultaneously.Through the analysis to the periodically automatic test result of emulation customer service behavior, Analysis server can in time obtain the key performance information of network element availability and performance, route availability and core net such as service availability and performance.

Fig. 2 representes the GRPS network of network topological diagram of the embodiment of the invention, and the difference of itself and Fig. 1 only is that SGSN passes through Gb Interface and is connected with PCU.The principle and the method for test data business are identical with above-described process.
