Problems solved by technology

Among them, the Q.AAL2 protocol can support the channel blocking function, and the MTP3B protocol can support the deactivation and prohibition of the link. Therefore, the combination of these two protocols can reduce the service load on the Iu interface board due to the failure of the Iu interface board to a certain extent. However, the processing process has certain delays and limitations, and it is impossible to completely avoid the loss of business data caused by the failure of the Iu interface board

Embodiment Construction

[0039] The main design idea of ​​the present invention is to solve various problems in the prior art scheme when the Iu interface single board fails or is upgraded and maintained, and provides a solution that does not increase the complexity of networking, does not change the interface protocol, and does not lose compatibility. Under the premise of reliability, the Iu interface boards that need to be upgraded and maintained are automatically completely isolated, and then the completely isolated Iu interface boards are upgraded and maintained to avoid damage to the Iu interface due to the upgrade and maintenance of the Iu interface boards. The data service carried on the single board will have a serious impact, so as to reduce the probability of call loss and improve the communication quality.

[0040] The main realization principle and specific implementation manner of the solution of the present invention will be described in detail below in conjunction with each accompanying ...

Abstract

The invention relates to an upgrade maintenance method of Iu interface, which comprises: selecting the Iu interface single plate waiting for upgrade maintenance; shielding loading service data to the selected Iu interface single plate; sending channel close request to each nearby node of Iu interface single plate; forbidding all signal chain circuits of selected Iu interface single plate; processing upgrade maintenance on the selected Iu interface single plate. The invention also discloses an upgrade maintenance system of Iu interface. The invention can avoid affecting the service data loaded on the upgraded Iu interface single plate, to reduce the consumption and improve the communication quality.

Description

technical field [0001] The invention relates to the technical field of interface security in the R4 version of the third generation network of the universal mobile communication system (UMTS 3G R4), in particular to a method for upgrading and maintaining an Iu interface single board and a system thereof. Background technique [0002] At present, in the R4 version of the third generation network of the universal mobile telecommunications system (UMTS 3G R4), the interface between the core network (CN, Core Network) and the universal terrestrial radio access network (UTRAN, UMTS Terrestrialradio access network) is based on asynchronous The Iu interface carried by the transmission mode (ATM, AsynchronousTransfer Mode), that is, the Iu interface is exactly the media gateway (MGW, Media Gateway) / service GPRS support node (SGSN, Service GPRS Supporting node) of the CN side and the radio network controller ( RNC, the interface between Radio Network Controller). Please refer to fi...
