Method for determining asynchronous reason of frame protocol transmission channel

Abstract

The invention discloses a method for determining nonsynchronous reason of frame protocol transmission channel, comprising the steps of: A. obtaining FP frame data between RNC and NodeB before and after non-synchronization; B. differentiating uplink and downlink FP frames and executing step C, or step D or step C and D; C. determining whether the time that RNC transmits downlink FP frame is stable or not: if unstable, determining the nonsynchronous reason is that the time that RNC transmits FP frame is unstable and determining whether the time that NodeB transmits uplink FP frame is stable or not: if unstable, determining the unstable reason of transmission channel is that the time that NodeB transmits uplink FP frame is unstable; D. determining whether actual TOA reported by NodeB is exact or not: if not exact, determining the nonsynchronous reason is that the actual TOA reported by NodeB is not exact. And it can automatically determine nonsynchronous reason of transmission channel.

Description

technical field [0001] The invention relates to a transmission synchronization technology in a mobile communication system, in particular to a method for determining an out-of-synchronization cause of a frame protocol (FP) transmission channel. Background technique [0002] In the third generation mobile communication system, in order to ensure the transmission of transmission data between the Iub interface and the Uu interface, the transmission channel synchronization technology is adopted between the radio network controller (RNC) and the base station (NodeB). The so-called transmission channel synchronization means that the RNC adjusts the sending time of the Transport Block Set (TBS), so that the TBS of the downlink can reach within the receiving window of the NodeB. The purpose of transmission channel synchronization is to ensure that the FP frame sent by the RNC can be within the processing range of the NodeB, and to reduce the cache and processing load of the NodeB. ...

AI Technical Summary

Problems solved by technology

[0007] 1. Using manual analysis to determine the cause of out-of-synchronization of the transmission channel depends to a large extent on the professional level of the technicians. At the same time, due to the slow speed of manual processing, the cause of out-of-synchronization cannot be reflected in time;

[0008] 2. The existing method for determining the asynchrony of the transmission channel can only be carried out during the working hours of the technicians, but it cannot be carried out under unattended conditions, the degree of automation is low, and the convenience of use is relatively poor
