Description
Technical Field
The present invention relates to data service transmission technology in the field of mobile communication, and in particular, to a disaster recovery method, device and system for an IP short message interworking gateway.
Background
With the widespread use of IP networks, IP short messages have also become one of the telecommunication service requirements. By introducing IP-SM-GW, the intercommunication between IP short message and circuit domain short message can be realized.
Taking the current deployment mode of China Mobile IP-SM-GW as an example, the China is divided into two large areas of south and north, and the IP-SM-GW will be respectively deployed in the two large areas in a centralized way and mutually backup disaster tolerance. And aiming at IP short message registration and MO flow, a S-CSCF detection mechanism commonly used in the industry is adopted to realize fault detection. In addition, two sets of IP-SM-GW addresses are sent to the S-CSCF during DNS analysis, and the IP-SM-GW of the corresponding area is preferentially accessed. If one IP-SM-GW fails, according to the HSTP configuration, the Message Transfer (MT) flow of the IP short Message is forwarded to another IP-SM-GW, that is: the IP-SM-GW is backed up for processing.
However, when the backup IP-SM-GW sends SRI request to HSS to query CS route, since the HSS stores the address of the failed IP-SM-GW, the IP-SM-GW address will be returned according to the HSS processing policy defined by the standard, such as the IP-SM-GW address stored by SRI request sender but not by HSS. Therefore, the process returns the address of the failed IP-SM-GW instead of the corresponding VMSC address, and the backup IP-SM-GW cannot issue the CS short message through the correct VMSC after receiving the reply, thereby causing the failure of the IP-SM-GW in issuing the CS short message. In addition, when the MT process domain is selected to the IMS domain, the MT process domain also needs to be inquired through the I-CSCF to be routed to the corresponding S-CSCF, and because short messages are frequently sent through the IMS domain, great pressure is brought to the I-CSCF.
