Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a system, and a related device for disaster recovery backup of a short message.
Background
Currently, a service flow of receiving an MT short message by a VoLTE (Voice over LTE, IMS-based Voice service) user is shown in fig. 1, and may include:
s11, sending the short message route information inquiry request to the VoLTE user home HSS/HLR by the sending part home SMSC.
In this step, a home SMSC (short message service center) of the sending party sends a query request of short message routing information (SRI _ for SM) to a receiving party HSS/HLR in a manner of a collimated connection via a Signaling Transfer Point (STP) of a seventh signaling network.
S12, the receiving HSS/HLR forwards the SRI _ for SM message to the receiving home IP _ SM _ GW.
In this step, for the SRI _ for SM sent by the sending SMSC, the receiving HSS/HLR forwards the SRI _ for SM message to the receiving home IP _ SM _ GW in a manner of a collimated connection via a Low Signal Transfer Point (LSTP) and a High-level Signaling Transfer Point (HSTP).
S13, the receiving party home IP _ SM _ GW sends the query request of SRI _ for SM to the receiving party home HSS/HLR.
S14, the receiver HSS/HLR returns the confirmation message of the SRI _ for SM inquiry request to the receiver IP _ SM _ GW.
In this step, for the short message routing information query request of the IP _ SM _ GW, the HSS/HLR returns a confirmation message, where the confirmation message carries the current VMSC (Visited Mobile Switching Center) GT (Global Title) and IMSI (International Mobile Subscriber identity) information of the receiver VoLTE Subscriber, and the receiver HSS/HLR may return the confirmation message of the short message routing information query request to the receiver IP _ SM _ GW by using an alignment mode of LSTP and HSTP.
S15, the IP _ SM _ GW of the receiver sends the SRI _ for SM confirmation message to the home SMSC of the sender.
In this step, the receiver IP _ SM _ GW sends the short message routing information contained in the SRI _ for SM acknowledgement message to the sender home SMSC, for example, the short message routing information may be IP _ SM _ GW global title GT, where the receiver IP _ SM _ GW sends the SRI _ for SM acknowledgement message to the sender home SMSC in a manner of a parallel connection via number seven signaling network LSTP and HSTP.
S16, sending part attribution SMSC sends short message to UE through receiving part IP _ SM _ GW.
In this step, the home SMSC of the sender sends the short message to the IP _ SM _ GW of the receiver by using a collimating connection mode of LSTP and HSTP through a number seven signaling network according to the received short message routing information.
IP _ SM _ GW tries to send down IP short message through IMS network, receives SIP MESSAGE message carrying MT short message through ISC and sends the SIP MESSAGE message to S-CSCF (Serving CSCF, service call session control function) selected in IMS registration process of the receiving party (called) user; the S-CSCF sends SIP MESSAGE information to a VoLTE SBC selected by the receiver VoLTE user during IMS registration according to path information during IMS registration of the receiver (called) user; the VoLTE SBC sends the IP short message to the receiver VoLTE subscriber through an IMS APN (Access Point Name, Access Point) default bearer of the receiver VoLTE subscriber.
And S17, if the IP _ SM _ GW fails to send the IP short message through the IMS network, sending the MT short message through the circuit domain.
Specifically, the IP _ SM _ GW transmits the MT short message to the VoLTE subscriber through the VMSC in the MAP manner according to the VMSC address obtained in step S14. In this step, the IP _ SM _ GW issues the MT short message through the circuit domain, and adopts a collimating connection mode through the number seven signaling network LSTP and HSTP.
As can be seen from the above flow of the VoLTE subscriber short message MT, when the IP _ SM _ GW fails, or the SMSC and the IP _ SM _ GW are disconnected, none of the steps S13, S14, S15 will be executed, or the execution is unsuccessful. At this time, the SMSC cannot receive the SRI _ for SM acknowledge message sent by the IP _ SM _ GW, so step S16 will not be executed to forward the user short message to the IP _ SM _ GW, resulting in a failure in sending the short message; because the SMSC has no disaster recovery mechanism, does not know the VMSC address of the CS domain of the user, and can not forward the short message to the VMSC to be transmitted through the 2/3G network, the VoLTE user can not receive the short message through the 4G network or the 2/3G network, the service is interrupted, and the bad influence is generated on the service perception.

Detailed Description
In order to solve the problem that a VoLTE user cannot receive a short message when an IP _ SM _ GW fails, embodiments of the present invention provide a short message disaster recovery backup method, apparatus, system, and related device.
The implementation principle of the short message disaster recovery backup method provided by the embodiment of the invention is as follows: when an internet protocol short message gateway IP _ SM _ GW fails, a sending party SMSC simulates the IP _ SM _ GW to send a short message routing information query request to a short message receiving party home subscriber server HSS/home location register HLR, and sends a short message to be sent to a receiving party according to short message routing information carried in a response message returned by the HSS/HLR. According to the short message disaster recovery backup method provided by the embodiment of the invention, when the IP _ SM _ GW fails, the VoLTE short message is sent down by the 2/3G network instead, and the problem that the VoLTE user cannot receive the short message is solved.
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are merely for illustrating and explaining the present invention, and are not intended to limit the present invention, and that the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.
As shown in fig. 2a, which is a schematic diagram of a general implementation flow of the short message disaster recovery backup method provided in the embodiment of the present invention, the method may include the following steps:
s21, judging whether the IP _ SM _ GW is in failure.
In this step, the sender SMSC determines whether the IP _ SM _ GW is faulty.
S22, if yes, simulating the IP _ SM _ GW to send a short message routing information inquiry request to a short message receiver home subscriber server HSS/home location register HLR.
In this step, when an IP _ SM _ GW (internet protocol short message gateway) fails, a sender SMSC (short message service center) simulates the IP _ SM _ GW to send a short message routing information (SRI _ for SM) query request to a short message receiver HSS (home subscriber server)/HLR (home location register).
S23, according to the short message route information carried in the response message returned by HSS/HLR, sending the short message to be sent to the receiving party.
In step S21, the sending SMSC may determine that the IP _ SM _ GW has failed according to the flow shown in fig. 2 b:
s211, the SMSC sends a short message routing information inquiry request to the HSS/HLR.
In specific implementation, after receiving a short message to be sent, the SMSC sends a short message routing information query request to the short message receiver HSS/HLR according to the prior art flow.
S212, if the response message of the short message routing information query request returned by the HSS/HLR is not received within the preset time length, the SMSC determines that the IP _ SM _ GW is in fault.
In specific implementation, in order to improve the accuracy of the judgment result of whether the IP _ SM _ GW has failed, after the SMSC sends a short message routing information query request to the short message receiver HSS/HLR for the first time, if a response message of the short message routing information query request is not received within a preset time period, the SMSC repeats sending the short message routing information query request to the HSS/HLR for N times, and does not receive a response message of the short message routing information query request returned by the HSS/HLR within the preset time period, and the SMSC determines that the IP _ SM _ GW has failed. Wherein, N is an integer greater than or equal to 2, and the N and the preset time length can be set in the SMSC equipment through software.
In this embodiment, the sending SMSC may pre-store address information of the IP _ SM _ GW, if the sending SMSC determines that the receiving IP _ SM _ GW is faulty, the sending SMSC simulates the receiving IP _ SM _ GW to send a short message routing information query request to the receiving HSS/HLR by using the stored address information of the IP _ SM _ GW, and the receiving HSS/HLR responds after receiving the short message routing information query request sent by the sending SMSC by using the address information of the receiving IP _ SM _ GW, that is, returns a response message of the short message routing information query request to the sending SMSC, where the response message carries short message routing information, so that the sending SMSC obtains the short message routing information provided by the HSS/HLR.
As shown in fig. 3, which is a schematic diagram of a specific implementation flow of the disaster recovery backup method for short messages according to the embodiment of the present invention, the method may include the following steps:
s31, the SMSC sends the short message route information inquiry request to the HSS/HLR.
In this step, the sending SMSC sends a short message routing information (SRI _ for SM) query request to the short message receiving HSS/HLR according to the existing flow, for example, the sending SMSC sends a short message routing information query request to the short message receiving HSS/HLR by using a collimation connection mode through the signaling network seven STP.
According to the embodiment of the invention, after sending the SRI _ for SM query request, the sending SMSC starts a timer to time.
S32, the home SMSC of the sender judges whether the response message of the SRI _ for SM inquiry request is received in the preset time length.
If the sending-party home SMSC receives the response message of the SRI _ for SM query request within the preset duration, the sending flow of the short message is the same as that of the prior art, and is not described herein again. The following description focuses on the processing flow of the sender home SMSC not receiving the response message of the SRI _ for SM query request within the preset duration.
According to the prior art process, for the SRI _ for SM sent by SMSC, HSS/HLR forwards the SRI _ for SM query request to the home IP _ SM _ GW of the receiving party, and the home IP _ SM _ GW of the receiving party queries SRI _ for SM to HSS/HLR of the receiving party. If the home IP _ SM _ GW of the receiver fails, the SRI _ for SM query request forwarded by the HSS/HLR of the receiver cannot be received, and then the SRI _ for SM cannot be queried to the HSS/HLR of the receiver, and the HSS/HLR of the receiver cannot return a response message of the SRI _ for SM query request to the SMSC of the sender through the home IP _ SM _ GW of the receiver, so that the SMSC of the sender can determine that the home IP _ SM _ GW of the receiver fails when the timing duration reaches the preset duration according to the timer.
Preferably, in order to ensure the accuracy of the determination result, the sending SMSC may further repeat the steps S31 and S32 for multiple times after the first timer reaches the preset duration, and if the acknowledgement message of the short message routing request is not received within the preset duration each time, it is determined that the receiving party belongs to the IP _ SM _ GW. Wherein, the repetition times can be set in the SMSC device through software.
The following describes a short message processing flow after the SMSC determines that the recipient home IP _ SM _ GW has failed.
S33, SMSC sends SRI _ for SM enquiry request to HSS/HLR of receiver by using pre-stored home IP _ SM _ GW address information of receiver.
In this step, when the sending-party home short message service center SMSC does not receive SRI _ for SM returned by the HSS/HLR within the preset duration, the SMSC determines that the IP _ SM _ GW fails, and then sends an SRI _ for SM query request to the HSS/HLR by using the pre-stored address information of the IP _ SM _ GW. That is, the sending SMSC simulates the home IP _ SM _ GW of the receiving party to send the SRI _ for SM query request to the HSS/HLR of the receiving party.
S34, HSS/HLR returns response message of SRI _ for SM inquiry request to SMSC.
The response message of the SRI _ for SM query request returned by the HSS/HLR carries short message routing information pre-stored by the HSS/HLR.
In this step, the short message routing information pre-stored by the HSS/HLR may include: VMSC GT (visited mobile switching center global title) and IMSI (international mobile subscriber identity) information.
S35, the SMSC sends the short message to be sent to the user through 2/3G network according to the SRI _ for SM returned by HSS/HLR.
The disaster-tolerant backup method for short messages shown in fig. 3 can be implemented by improving the SMSC of the sending party.
In the disaster recovery backup method for short messages provided in the embodiments of the present invention, when an IP _ SM _ GW fails, a sending party SMSC simulates the IP _ SM _ GW to send a short message routing information query request to a home subscriber server HSS/home location register HLR of a short message receiving party, and sends a short message to be sent to the receiving party according to short message routing information carried in a response message returned by the HSS/HLR.
When the IP _ SM _ GW fails, the VoLTE short message is sent by the 2/3G network instead, and the problem that the VoLTE user cannot receive the short message is solved.
The short message disaster recovery backup method provided by the embodiment of the invention can be realized by only performing software modification on an SMSC (short message service center) and adding a disaster recovery processing mechanism, other network elements do not need to be modified, the operation is simple, the practicability is higher, and the rapid deployment is convenient.
