Processing method and processing device after communication port fault

Abstract

The invention discloses a processing method after a communication port fault, which comprises the following steps: when NCP has a fault, transceiving a transmission bearing link corresponding to common part information using CCP according to bandwidth calculation; when the CCP has a fault, transceiving a transmission bearing link corresponding to special information of a user using other CCP or NCP, of the fault CCP according to the bandwidth calculation; and when the faults are eliminated or CCP load is reduced, according to corresponding relation of common part information and the NCP beforethe faults, recovering the transceiving of the transmission bearing link corresponding to the corresponding NCP used by the corresponding relation, and according to corresponding relation of the special information of the user and the CCP before the faults, recovering the transceiving of the transmission bearing link corresponding to the corresponding CCP used by the corresponding relation. The invention also discloses a processing device after the communication port fault, which comprises a load control module and a route selection module.

Description

technical field [0001] The invention relates to a third generation mobile communication system (3G), in particular to a processing method and device for a failure of a communication port in the third generation mobile communication system. Background technique [0002] In the 3G communication system, the Node B (base station) application part (Node B Application Part: NBAP) completes the control function of the Iub interface, including the public part and the private part. Among them, the public part of the message is sent and received through the transmission bearer link corresponding to the Node B Control Port (NCP), and the private part of the message is sent and received through the transmission bearer link corresponding to the Communication Control Port (CCP). Here, NCP and CCP are collectively referred to as communication ports. [0003] The protocol stipulates that there is only one NCP from a radio network controller (Radio Network Controller: RNC) to a Node B, but ...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the existing technology is: if the transmission bearer link corresponding to the NCP fails in the active / standby mode, even if the transmission bearer link corresponding to the CCP is still available, since the public part of the NBAP message cannot be transmitted, the subsequent users will not be able to carry out the wireless link. The establishment of the radio link (RL) makes the base station unavailable

Although there can be multiple transmission bearer links corresponding to a CCP, there is no dynamic adjustment of the corresponding relationship between the CCP and the transmission bearer link when the transmission bearer link corresponding to the CCP fails according to the actual situation.

When the transmission bearer link corresponding to the CCP fails, because the related Node B Communication Context (Node B Communication Context: NBCC) allocated on the CCP cannot continue to perform signaling interaction through the CCP, the allocation on the CCP NBCC will be released, causing users to drop calls

[0005] The above shortcomings are more prominent when the business load is not large, that is, the bandwidth used by the messages sent and received by the NCP and the CCP is relatively small, that is to say, even if the bandwidth required by NBAP signaling is small, the remaining bandwidth that the Iub port can still provide There are still many, but because of the fixed one-to-one correspondence between NCP or CCP and the transmission bearer link, dynamic adjustment cannot be realized, and the base station will be unavailable or the user will drop calls due to transmission bearer link failure and other reasons

[0006] Application No. 200510090893.4 of the Chinese patent application "A Method for Improving the Reliability of Iub Port Signaling Links" proposes a method for providing backup transmission bearer links for NCP and CCP respectively. When a transmission bearer link fails It is possible to use the spare transmission bearer link to continue the communication, but generally speaking, the total signaling bandwidth of the Iub port is fixed. This method will consume a lot of bandwidth resources of the Iub port, especially for each CCP to provide a spare transmission bearer link , which is difficult to implement in real applications

[0007] It can be seen that the existing technology does not solve the problem of ensuring that NBAP signaling continues to be sent and received after NCP or CCP failures, and that the connected users do not drop calls.
