Based on the in-depth analysis of problems upon disaster tolerance and called-number recovery in actual network deployment of Henan Mobile, the paper put forward an effective solution, which introduces the VLR Restore process within 3GPP into the MSC Pool disaster recovery scenarios, and realizes the automatic switching of HLR routing data by using SCCP backup addressing. Through large numbers of simulated experiments, this program solved the problem of called-number recovery in core network disaster tolerance scenarios, can restore the call automatically immediately. Moreover, the program utilizes the open protocols with zero investment and is compatible with different equipment manufacturers and software versions.
