METHOD, SYSTEM AND DEVICE FOR CALLED PARTY RECOVERY IN MOBILE SWITCH CENTER POOL
First Claim
1. A method for called party recovery in a Mobile Switch Center (MSC) Pool, applied in a system that comprises a Home Location Register (HLR) and an MSC Pool including multiple Mobile Switch Centers/Visitor Location Registers (MSC/VLRs), comprising:
- configuring a backup server for each MSC/VLR in the MSC Pool;
the method further comprising;
if an MSC/VLR serving a user is down, the user does not initiate a calling service or a location update, and the user is called,sending, by the HLR, a call signaling to the backup server of the MSC/VLR that is down;
initiating, by the backup server of the MSC/VLR, a paging request to the user and initiating a location update for the user to the HLR;
registering, by the HLR, user data of the user at the backup server of the MSC/VLR and switching the MSC/VLR serving the user to the backup server of the MSC/VLR.

Abstract
A method for called party recovery in an MSC Pool, applied in a system that comprises an HLR and an MSC Pool including multiple MSC/VLRs, includes configuring a backup server for each MSC/VLR in the MSC Pool; if an MSC/VLR serving a user is down, the user has not initiated any calling service or location update and the user is called, further includes: the HLR sending a call signaling to the backup server of the MSC/VLR that is down; the backup server of the MSC/VLR initiating a paging request to the user and initiating a location update for the user to the HLR; the HLR registering user data of the user at the backup server and switching the MSC/VLR serving the user to the backup server. The present invention also discloses other methods, systems and devices, which can solve the problem of called party recovery in the MSC Pool.
