Method of updating remote subsystem in mobile communication system

Abstract

This invention discloses a method for upgrading remote sub-systems in a mobile communication system, in which, a maintenance center gets the current software edition and hardware configuration of a remote sub-system first, then matches them with those being upgraded to generate a software module necessary to be downloaded and packs the software modules to be transmitted and transmits them together.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to the management and maintenance technology of the remote subsystem in the mobile communication system. Background technique [0002] Wideband Code Division Multiple Access ("WCDMA") is one of the three mainstream standards of the third generation mobile communication (the 3rd Generation, "3G"). It inherits the existing global mobile communication The system (Global Systems for Mobile communications, referred to as "GSM") features a high degree of standardization and good openness, and has good compatibility and interoperability with the GSM network. It is one of the development trends of mobile communications in the future. [0003] The basic structure of the Radio Access Network ("RAN" for short) side of the WCDMA system is as follows: figure 1 shown. [0004] In a WCDMA system, the RAN side includes a Radio Network Controller (Radio Network Controller, "RNC") 20 and a Node ...

Problems solved by technology

[0010] In practical application, the above scheme has the following problems: the efficiency of the NodeB software upgrade scheme in the existing WCDMA system is low, and the software upgrade takes a long time

[0011] The main reason for this situation is that the WCDMA system is relatively complex, there are many types of service boards, and the types and sizes of software required by each service board are different. The software of the entire NodeB occupies a large storage space. A NodeB system software upgrade is usually only because some software modules need to be updated, and most software modules do not need to be updated; at the same time, the functions supported by each NodeB and the required software modules are not the same, and the communication interface with the RNC can be Optical interface or electrical interface, or even a hybrid interface that supports both interfaces. Some base station systems need to configure additional boards with extended functions, while some base station systems do not. Such an upgrade process will face a large number of different hardware and software-configured base station systems

[0012] Technical solution 1. Download all the software on the NodeB through the remote transmission channel, and indiscriminately upgrade all the base station software modules. This will cause many software modules that are not needed or not supported by the NodeB to be transmitted, which is very inefficient. Since the bandwidth of the IPOA maintenance channel is configured by the operator, usually only tens of K, if the upgrade software is too large, the transmission time will be very long, especially when multiple NodeBs upgrade the software version at the same time, if the verification operation of the subsequent update version is also considered Or the version rollback time, the time left for the software version upgrade process is not enough

[0013] Although technical solution 2 has carried out the version comparison, it does not consider that the upgrade process will face a large number of NodeBs with different software and hardware configurations, nor does it consider the situation that some base station systems need to be upgraded to add some functional software modules, resulting in software version matching The process is more difficult and the efficiency is not high; and because the number of software modules required by Nodeb is large, when the number of software modules to be updated is also large, a large number of software modules need to be transmitted, and for the transmission of each software module In terms of the process, a connection of a certain transmission mode will be established first, then the transmission will be performed, and the connection will be released at the end, and the cycle will repeat until all the software modules are transmitted. In this way, multiple software modules need to establish and release multiple connections, which also results in low efficiency of software upgrades.
