Problems solved by technology

However, this method also has some shortcomings, for example: the version upgrade period is long and lacks flexibility; and the EPLD logic cannot be synthesized into the major software CPU version and upgraded together due to its characteristics. If there is an upgrade demand for EPLD, There is also an urgent need for a remote system-level upgrade method

Embodiment Construction

[0041] The main purpose of the present invention is to solve the problem of how to operate the BTS online through a remote maintenance terminal such as a background PC under the normal operation of the BSC and the base station transceiver BTS, so as to realize the upgrading of logical hardware versions such as FPGA and EPLD of the BTS system problems while effectively improving the efficiency and reliability of the upgrade process.

[0042] To achieve the above object, the main idea of ​​the present invention is described as follows:

[0043] JTAG is a PCB (Printed Circuit Board, printed circuit board) and IC (Integrated Circuit, integrated circuit) test standard initiated by several major electronics manufacturers such as IBM, Siemens, Ericsson, TI, AT&T, Philips, and Alcatel. JTAG was approved by IEEE (Institute of Electrical and Electronics Engineers, Institute of Electrical and Electronics Engineers) in 1990 as the IEEE1149.1-1990 test access port and boundary scan structu...

Abstract

The invention discloses a method and device for remotely upgrading logic devices of a base station system. After the main control board of a base station transceiver stores the upgraded version, it addresses the port of the controlled board where the logic device to be upgraded is located through a JTAG port, and notifies the controlled The identification information of the logic device to be upgraded on the board; after the controlled board addresses the logic device to be upgraded according to the identification information, it returns an addressing response signal to the main control board; after the main control board receives the addressing response signal, the logic device to be upgraded Load the upgraded version. The present invention adopts a base station system remote hardware version upgrade method based on JTAG technology, and realizes that when the BTS and BSC are in normal operation, the remote version upgrade can be performed on the background terminal without getting off the station, the operation is flexible and reliable, and can be used as the current version upgrade A better addition to the method.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and device for remotely upgrading logic devices of a base station system. Background technique [0002] In the field of wireless communication, BTS (Base Transceiver Station, Base Transceiver Station) realizes the role of communication bridge between BSC (Base Station Controller, Base Station Controller), core network, radio frequency terminals and users. The reliability and quality of the BTS system directly affect the stability and quality of the entire communication system. The BTS system is generally composed of many hardware system boards, and there are a large number of FPGA (Field Programmable Gate Array, Field Programmable Gate Array) and EPLD (Erasable Programmable Logic Device, erasable programmable logic device) chip applications on the single board. FPGA is mainly used to process signals such as communication baseband radio frequency, and real...
