Description
Technical field
The present invention relates to the network communications technology, particularly Gateway GPRS Support Node and group data service node testing functions of forwarding actual services method are a kind of testing functions of forwarding actual services at communication nodes method specifically.
Background technology
Gateway GPRS Support Node (GGSN) is the equipment of the core network of global mobile communication system (GPRS/UMTS), the critical point function of packet radio domain core net and Packet Data Network (for example Internet) is provided, between the main frame or router on mobile phone and the internet, the effect of playing carrying and transmitting the IP operation message.The position of GGSN in the GPRS/UMTS network as shown in Figure 1, its external interface is as shown in Figure 2.
The GGSN product needed through system design validation (SDV), System Integration Test a series of tests such as (SIT) before the merchant that formally goes into operation.Wherein, SDV, SIT often need carry out in the laboratory of equipment manufacturers.These test activities will be verified fully and test all functions characteristic of GGSN product and performance.
GGSN is transmitted the test of mobile phone IP operation message functional characteristic, and to the content charging of GGSN and Qos etc. and the test that is forwarded the closely-related functional characteristic of IP message, usual way is: by the testing tool of equipment manufacturers oneself exploitation, or commercial instrument, as K1297, Smartbits etc., or business software, as Sniffer, NetXRay etc., the equipment of simulation and GGSN interface:, construct concurrent capable GTP (GPRS Tunnel Protocol) data message of serving at serving GPRS support node (SGSN) equipment of gn interface artificial antenna core net; Main frame or router on Gi interface simulation internet, structure also sends the downstream IP data message.Observe described GGSN then and whether correctly uplink message has been forwarded to described Gi interface, downlink message has been forwarded to described gn interface.Encapsulation format in the uplink data messages of described gn interface structure is generally: " L2/IP/UDP/GTP/IP/ data " (for simplifying text description, use the protocol hierarchy of "/" symbolic representation protocol massages.In the message, the protocol stack level in "/" left side is lower than the level of its right side protocol stack.In addition, L2 refers to arbitrarily the link layer protocol encapsulation, such as, can be the Ethernet encapsulation), wherein, by " IP/ data " layer message emulating of " GTP " layer encapsulation cellphone subscriber's practical IP service message.Encapsulation format at the downlink data message of described Gi interface structure is generally: " L2/IP/ data ", wherein, time emulation of " IP/ data " layer message main frame on the internet or the practical IP service message of router.In the uplink data messages encapsulation of described gn interface structure, " IP/ data " message that is carried by GTP is also by testing tool, instrument, software construction, or derive from the message that several simple real IP are used, such as the message of PING program (a kind of Software tool of test network connectedness).Use the gn interface of this emulation that the IP operation message is tested following shortcoming: to be difficult to simulate fully real IP service message miscellaneous actual on the existing network, no matter be class of business (such as FTP, HTTP, VOD, Email or the like), or the message transmitting spped rate etc. of message length and variation thereof, IP message, the defective that exists in the GGSN forwarding capability that can't find to have only the application-specific business just can trigger; More can't experience of the influence of the data forwarding function of GGSN conscientiously to the real IP business, such as, of short duration time-delay and slight packet loss when GGSN E-Packets can cause that the VOD demonstration is professional significant the broadcast to be occurred and pause, and allow the people recognize existing problems immediately.But in not having the laboratory tests environment of whole network equipment, of short duration time-delay and slight packet loss also can not cause tester's concern.
At present in order to solve the problem that exists in the above-mentioned method of testing, build the whole network test environment of CPRS/UMTS, purchase the whole network equipment of equipment such as comprising mobile phone, NodeB, radio network controller (RNC), attaching position register (HLR:Home Location Register), SGSN.After normal operation of all devices and the correct configuration,,, start the real IP business, whether judge normally by the execution of observing application program whether the data forwarding function of GGSN is correct such as the internet browser by the application program on the mobile phone.This method of testing shortcoming is to have high input, the cost height, and often have various resource limit, such as quantity of mobile phone or the like, cause test activity and range limited, not exclusively be adapted at carrying out in the laboratory tests in stages such as SDV, SIT.
GGSN is handled the test of PPP (PPP:Point-to-Point Protocol) signaling, IP datagram literary composition functional characteristic, usual way is: by the testing tool of equipment manufacturers oneself exploitation, or commercial instrument, as K1297, Smartbits etc., or business software, as Sniffer, NetXRay etc., the equipment of simulation and GGSN interface:, construct the concurrent capable GTP data message (being divided into GTP/PPP signaling and GTP/PPP/IP data) of serving at the SGSN equipment of gn interface artificial antenna core net; Main frame or router on Gi interface simulation internet, structure also sends the downstream IP data message.Observe the ability of GGSN processing PPP signaling message then, whether correctly up PPP+IP data message is peeled off the PPP head, the IP data forwarding has been arrived the Gi interface, downlink message is added that the PPP encapsulate forwarded has arrived gn interface.
Encapsulation format in the uplink data messages of gn interface structure is generally: " L2/IP/UDP/GTP/PPP/IP/ data ", wherein, by " PPP/IP/ data " layer message emulating of " GTP " layer encapsulation cellphone subscriber's actual PPP service message.
Encapsulation format at the downlink data message of Gi interface structure is generally: " L2/IP/ data ", wherein, " IP/ data " layer message emulating main frame on the internet or the practical IP service message of router.There is following defective in this method of testing: in the uplink data messages encapsulation of gn interface structure, " PPP/IP/ data " and " PPP signaling " message that is carried by GTP is also by testing tool, instrument, software construction.Use the gn interface of this emulation that the PPP service message is tested, be difficult to simulate fully miscellaneous true PPP service message actual on the existing network, no matter be the IP message length that carries of PPP and variation thereof, IP message class of business (such as FTP, HTTP, VOD, Email or the like), or message transmitting spped rate, or the like, thereby the defective that exists in the GGSN forwarding capability that can't find to have only the application-specific business just can trigger; Do not reach simultaneously the purpose of the compatibility of test GGSN and different operating system ppp protocol stack yet.
In order to solve the problem that exists in the above-mentioned method of testing, build the whole network test environment of GPRS/UMTS at present, purchase the whole network equipment of equipment such as comprising mobile phone, NodeB, RNC, HLR, SGSN.After normal operation of all devices and the correct configuration,,, start the PPP business, observe the response condition of dial-up program such as dial-up program by the application program on the mobile phone.After treating dial-up success, start the IP operation program,, start the PPP bearer IP service, whether judge normally by the execution of observing application program whether the data forwarding function of GGSN is correct such as IE, FTP.The shortcoming of this method is: have high input, cost height, and often have various resource limit such as quantity of mobile phone or the like, causes test activity and range limited, not exclusively is adapted at carrying out in the laboratory tests in stages such as SDV, SIT.
As Fig. 9 and shown in Figure 10, the network reference model of CDMA2000 (a kind of 3G (Third Generation) Moblie standard) packet subsystem comprises based on the network reference model of simple IP with based on two kinds of the network reference model of mobile IP.Wherein packet data serving node (PDSN:Packet Data Serving Node) between packet-based core networks and CDMA2000 wireless access network, is in charge of User Status, transmits user data, and is portable terminal distributing IP address.
As shown in Figure 9, the packet core network based on simple IP mainly comprises packet data serving node (PDSN:Packet Data Serving Node), remote authentication dial access service (RADIUS:Remote Authentication Dial In User Service) server etc.Radius server is arranged in packet-based core networks, mainly finishes the function of authentication, acts on behalf of radius server and is responsible for transmitting the authentication and the charge information of visiting between radius server and the ownership radius server.
As shown in figure 10, the packet subsystem based on mobile IP also should comprise home agent (HA:Home Agent) except comprising PDSN and radius server.HA is responsible for to user's distributing IP address grouped data being sent to the mobile subscriber by tunneling technique, and realizes the macro-mobility between the PDSN.Simultaneously, PDSN also should increase visit agency's (FA:Foreign Agent) function, is responsible for providing tunnel exit, and will mails to travelling carriage after the data decapsulation.
The PDSN product needed a series of tests through aspects such as performance and pressure before the merchant that formally goes into operation.PDSN is carried out the test of performance and pressure aspect, and the test of carrying out service quality (QoS:Qualityof Service) effect, flow jitter etc., usual way is: the own development and testing instrument of equipment producer, analogue mobile phone activates and the up-downgoing data forwarding, finishes the test of PDSN performance and pressure aspect with this.Whether have following shortcoming but be to use the method to test: the function of testing tool often is confined to analogue mobile phone and activates, construct several common IP packet test PDSN and can normally transmit; Be difficult to simulate fully real IP service message miscellaneous actual on the existing network, no matter be class of business (such as FTP, HTTP, VOD, Email or the like), or the message transmitting spped rate or the like of message length and variation thereof, IP message, thus the problem that exists in the PDSN forwarding capability that can't find to have only the application-specific business just can trigger; And the test effect is relatively poor.
At present in order to solve the problem that exists in the above-mentioned method of testing, build the whole network test environment of CDMA2000 in the laboratory, purchase equipment such as mobile phone, radius server, Packet Control Function (PCF:Packet ControlFunction), attaching position register (HLR:Home Location Register), router, utilize mobile phone PDSN to be carried out functional test after the networking is finished in conjunction with the whole network environment.This method of testing shortcoming is to have high input, and cost height, and often have various resource limit such as quantity of mobile phone or the like, can only carry out the test of simple functions to PDSN, can't carry out the test of performance, pressure and unusual flow process; Be not suitable for the product test of equipment producer.
