Apparatus for test number transmission ability between networks

Abstract

The invention provides a device for testing the capacity for transmitting numbers between networks, which comprises a massage receiving and transmitting module, a massage processing module, a signaling message processing module and a statistic output module, wherein the massage receiving and transmitting module is used for analyzing IP data packets which are sent by a core network element, and then sending the packets to the massage processing module, the massage processing module is used for carrying out the protocol dissection process to the messages which are analyzed, and then sending themessages to the signaling message processing module, the signaling message processing module is used for identifying the type of the messages which are sent by the massage processing module, and thenaccording to a pre-determined distributing mechanism, distributing the messages to each of analog exchangers which are preset, the statistic output module is used for recording the messages which arereceived by each of the analog exchangers and are sent by the signaling message processing module, and then transmitting the messages and the pre-stored numbers to be compared with the standard specification, and then finding abnormal call messages. The device can simulate a plurality of the exchangers which are connected with the core network element, and can improve the trueness of the capacityfor transmitting the numbers between the networks.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a device for testing the number transmission capability between networks. Background technique [0002] With the continuous development of communication technology, Voice over Internet Protocol (VOIP) technology in packet packet switching technology has gradually matured, and this technology has been widely used in fixed and mobile fields. To connect the existing circuit-switched network switch to the Next Generation Network (NGN), an intermediate access link is required, which is connected to the IP layer through the relay gateway and the signaling gateway in the existing network. As the core network element of the NGN tandem level, it needs to access a large number of circuit-switched switches to process a large number of No. 7 messages from these circuit switches, including ISDN User Part (ISUP) and telephone user part ( TelephonyUser Part, TUP), completes the contr...

Problems solved by technology

[0005] (1) Since it is impossible to provide a large number of physical circuit switches in the laboratory, such as switches that realize functions such as end offices, long-distance offices, and mobile gateway offices, it is impossible to implement exchanges for various standards, models, and number specifications Interaction tests with relays or signaling gateways, resulting in false test results;

[0006] (2) In the existing test technology, there are hardware devices for testing performance calls. The method is usually to simulate one or several office-directed switches, send a large number of call messages, and examine the call processing capabilities of core network elements, but the implementation is simulated Call performance cannot simulate all switches connected to core network elements, and there is no function of recording and analyzing number specifications; in addition, such hardware equipment is expensive, which is also a factor restricting its application
