Embodiment Construction

[0044] In a system that uses the Inverse Multiplexing for Asynchronous Transfer Mode (IMA) technology to realize data transmission, in order to reduce the false positive rate of the detection result when performing mixed line detection, in the embodiment of the present application, The sending end sends a test signal for detecting the mixed line situation to the communication peer side through the first link, and the test signal at least contains a first identifier for uniquely identifying the first link; then, the sending end Receive a response signal returned by the communication peer side through the second link, the response signal at least contains a second identifier used to uniquely identify the second link, and the unique identifier received by the communication peer side. The third identification of a certain link; finally, the transmitting end compares the first identification with the third identification, and when learning that the two are inconsistent, determines t...

Abstract

The invention discloses a method for detecting IMA E1 link hybrid lines. The method comprises that: a transmitting end sends a test signal for detecting hybrid line conditions to a communication opposite end side through a first link, wherein the test signal at least comprises a first mark for uniquely marking the first link; then, the transmitting end receives a response signal returned by the communication opposite end side through a second link, wherein the response signal at least comprises a second mark for uniquely marking the second link and a third mark received by the communication opposite end side for uniquely marking a certain link; and finally, the transmitting end compares the first mark with the third mark, and determines that the first link and the second link are hybrid according to the first mark and the second mark when the first mark and the third mark are not consistent. Therefore, the method effectively avoids the occurrence of erroneous judgment and greatly improves the accuracy of hybrid line detection results. The invention also discloses a communication device and a communication system at the same time.

Description

technical field [0001] The present application relates to the field of communications, and in particular, to a method, device and system for detecting IMA E1 link mixing. Background technique [0002] At present, in the third-generation mobile communication system, the IUb interface between the radio network controller (Radio Network Controller, RNC) and the base station (NodeB) generally adopts Inverse Multiplexing for Asynchronous Transfer Mode (IMA) ) technology to realize data transmission. The so-called IMA technology refers to bundling multiple low-speed physical links (such as 30 pulse code modulation links based on European standards, referred to as E1 links) into a logical high-speed link (hereinafter referred to as IMA) through IMA technology. E1 link). For example, see figure 1 As shown, the three E1 links of physical links #0, #1 and #2 are bundled into one IMA E1 link using the IMA technology to transmit the ATM cells represented by a, b, and c. [0003] In ...
