Example Embodiment

[0027] The specific embodiments of the present invention will be described below with reference to the drawings in the specification.

[0028] For the two ends of the device where IPOA channel is blocked, the location analysis is started from the physical layer, ATM layer and IP layer. Three-layer positioning sequence: first physical layer, then ATM layer, then IP layer or first IP layer, then ATM layer, then physical layer.

[0029] The following describes the first physical layer query as an example.

[0030] First, the physical link carrying the IPOA channel is separated, that is, other service data is not carried by the physical link, so as not to affect other services.

[0031] Specific query methods such as figure 2 , image 3 As shown, including the following steps:

[0032] Step 11: Query the physical link on the RNC side that carries the IPOA channel, such as: UNI (User-Network Interface) link, IMA (Inverse Multiplexing for ATM, ATM inverse multiplexing technology) link a...

Abstract

The invention discloses an asynchronous transformation mode carrying IP data channel error locating method that would take locating to IPOA channel error according IP layer, ATM layer an physical layer according to IPOS channel transformation protocol layer. The method includes the working state of physical link detecting, PVC link detecting and IP route analysis. The invention could realize rapid error locating.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for locating faults in an asynchronous transfer mode bearing IP data (IPOver ATM, IPOA) channel. Background technique [0002] All communication networks are generally based on the communication between peer layers of the protocol. In the WCDMA network, the communication between IPOA channels is also based on this basic principle. Specific protocols and communication models such as figure 1 Shown: the black solid line represents an IPOA channel between RNC (Radio Network Controller, radio network controller) and NodeB (base station), and the dotted line represents the concept of peer layer, including IP layer, asynchronous transfer mode (Asynchronous Transfer Mode, ATM) layer and physical layer. The RNC can perform operation and maintenance on the NodeB through the IPOA channel, and the NodeB can also send request information, such as a Bootp (Bootstrap Protocol, ...
