Abstract:
1. A method for implementing online maintenance in communication network, comprising: detecting, by a communication device of the communication network, during a communication procedure a maintenance request sent from a user terminal; recording, in the communication device, communication data going through the communication device itself when the communication device has detected the maintenance request; collecting, by an online maintenance server, the communication data recorded in part of or all communication devices in the communication network during the communication procedure; and analyzing the communication data to find out a fault reason of the communication network; wherein the collecting communication data during the communication procedure comprises: sending, from the online maintenance server, a maintenance data collect request to the communication device; encapsulating, by the communication device, the recorded communication data going through the communication device itself during the communication procedure into an IP package after receiving the maintenance data collect request, and sending an IP packet to the online maintenance server; wherein the analyzing the communication data to find out the fault reason of the communication network comprises: starting, by the online maintenance server, fault reason analysis; selecting two communication data from the collected communication data for comparison, wherein the two communication data carry global unique identifiers indicating the same communication procedure and are sent from two adjacent communication devices in the communication network, respectively; and determining, by the online maintenance server, that a fault lies in the communication devices having sent the two communication data when the two communication data are different.
