System and method for testing bearer independent call control (BICC) service under access network-free condition

Abstract

The invention provides a system and a method for testing a bearer independent call control (BICC) service under an access network-free condition. The method comprises the following steps that: a calling audio / video session initiation protocol (SIP) terminal sends an SIP calling invitation message; an R4 simulation test platform converts the SIP calling invitation message into a BICC initial address message, sends the BICC initial address message to a tested BICC service system and establishes a 3G-224M media passage of the tested BICC service system for a calling user; the R4 simulation test platform continues establishing an RTP media passage of the calling audio / video SIP terminal; and the R4 simulation test platform bridges the established RTP media passage and the 3G-224M media passage. The system and the method belong to the field of network communication and can test various BICC service products under a TD or WCDMA network-free condition according to the simulation and media display of various calling / answering states by calling and called audio / video SIP terminals. Therefore, test cost is saved and high expandability is achieved.

Description

technical field [0001] The invention relates to a BICC service testing system and method under the condition of no access network, and belongs to the technical field of network communication. Background technique [0002] With the development of the third generation (3G) network, more and more TD or WCDMA services accessed based on the R4 BICC protocol have been widely used, such as teaser cool show, video enhancement, IVVR, IVDR, V network companion call Service BICC version, etc. [0003] At present, the internal commissioning of these services based on BICC protocol access (abbreviated as BICC service) in a non-TD or WCDMA network mainly uses BICC simulation test scripts for simple process signaling commissioning. In practice, this test scheme has a relatively large limitation: [0004] 1. The signaling process that can be commissioned by using the simulation test script is limited to simple processes. It is difficult to simulate abnormal or complex processes using the ...

Problems solved by technology

[0003] At present, the internal commissioning of these services based on BICC protocol access (abbreviated as BICC service) in a non-TD or WCDMA network mainly uses BICC simulation test scripts for simple process signaling commissioning. In practice, this test scheme has a relatively large limitation:

[0004] 1. The signaling process that can be commissioned by using the simulation test script is limited to simple processes. It is difficult to simulate abnormal or complex processes using the simulation test script, such as the called mobile phone is turned off during the call, and the called mobile phone refuses to answer, etc.;

[0005] 2. The commissioning of the simulation test script can only be based on the signaling level, and cannot display R4’s audio RTP / Nbup media and video 3G-324M / Nbup media, especially for BICCs that mainly display media such as Teaser Cool Show and IVVR For business products, the business functions provided cannot be tested by using mock test scripts;

[0006] 3. It is difficult to control the timing of secondary dialing during the call using the simulation test script commissioning

This technical solution requires the use of mobile switching centers and media gateways with enhanced functions, which increases the test costs in laboratories, companies, etc. , codec negotiation and video communication process to obtain test information. The quality of the tested telephone service is limited and cannot be displayed through the real media during the calling process of the calling and called terminals. For various calls / answers under normal or abnormal status , and the BICC business process based on media presentation for simple, intuitive and comprehensive simulation and presentation
