Problems solved by technology

[0010] In order to overcome the problem of manually configuring the relationship between Path ID and VPI / VCI due to the absence of a mapping table for the relationship between Path ID and VPI / VCI during the signaling test of the prior art Due to the inefficiency and dependence on network management in the mapping table, the present invention proposes an automatic identification method for the mapping relationship between link identifiers, virtual paths and virtual channels

Embodiment Construction

[0022] attached figure 2 It is a schematic diagram of a specific embodiment of the method for automatically identifying the mapping relationship between a link identifier and a virtual path and a virtual channel in the present invention. It can be seen from the figure that the automatic identification method of the mapping relationship between the link identifier and the virtual path and virtual channel in the present invention includes a method of gradually narrowing the matching range based on CID matching.

[0023] Judging the correspondence between a Path ID and a VPI / VCI is mainly based on the following principles:

[0024] 1. The AAL2 links on the Iub interface are allocated through the ALCAP protocol;

[0025] 2. The FP protocol of the newly allocated AAL2 link will have a synchronization process. If the FP synchronization message is received, the AAL2 link is allocated by the ERQ message of the ALCAP protocol;

[0026] 3. The scope of use of Path D in the Iub interf...

Abstract

In order to overcome the problems of low efficiency and dependence on network management in a mapping list in which Path ID and VPI / VCI relationship is manually collocated since no mapping list with Path ID and VPI / VCI relationship exists in the signaling test process of the prior art, the invention discloses an automatic identifying method of the mapping relationship of chain path identification and virtual paths and virtual channels. By applying the automatic identifying method of the mapping relationship of the chain path identification and the virtual paths and the virtual channels provided by the invention, real-time data with certain quantity in the network can be analyzed, so the mapping relationship of each Path ID and VPI / VCI can be rapidly and automatically identified, the mapping relationship list of the Path ID and VPI / VCI of each Iub interface can be obtained in a real-time manner by manual collocation without need of network management, and the complete and deep signaling monitoring and protocol analysis can be carried out.

Description

technical field [0001] The present invention relates to signaling test technology in the third generation mobile communication system (abbreviated as 3G), in particular to an automatic identification method of PathID and VPI / VCI mapping relationship on the Iub interface in the signaling test technology of 3G mobile communication network. Background technique [0002] In the data transmitted by the communication network, in addition to the user data, there is also a part of the message used to control the transmission, which is usually called signaling. The signaling test of the network can reflect the overall operating status of the network, grasp the operating status of the network, and effectively help network engineers to carry out work such as fault diagnosis, service quality evaluation, and network optimization of the communication network. During the signaling test process, the signaling network needs to be monitored. The signaling messages between the network interfa...
