Preferred embodiment of the invention

The present application will be described in detail below with reference to the drawings in conjunction with the embodiments. For convenience of description in the following embodiments, the user's real network number is set as the primary number (denoted as P-MSISDN), and the primary number is used for the overhead user. The user can bind one or more virtual numbers to the secondary number (denoted as S-MSISDN), and the secondary numbers are all opened on the HLR (Home Location Register), and there is a separate IMSI (International Mobile Subscriber Identification Number). , International Mobile Subscriber Identity (IDI) and MSISDN (Mobile Station International ISDN number; where ISDN is Integrated Services Digital Network, Integrated Services Digital Network), but no real information such as location, need to be attached to the main number In use, the secondary number has a virtual state such as a switch.

It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

An embodiment of the present invention provides a method for terminating a short message. FIG. 1 is a flowchart of a method for terminating a short message according to an embodiment of the present invention. As shown in FIG. 1, the method includes:

S102. The service control point SCP registers the address information of the SCP as the home location information of the secondary number in the home location register HLR.

S104. The SCP receives a short message that is forwarded by the short message center SMSC according to the home location information.

S106. The SCP obtains the primary number information corresponding to the secondary number, and routes the short message to the corresponding terminal according to the primary number information.

According to the embodiment of the present invention, the service control point SCP registers the address information of the SCP as the home location information of the secondary number in the home location register HLR; the SCP receives the short message forwarded by the short message center SMSC according to the home location information; The SCP obtains the primary number information corresponding to the secondary number, and routes the short message to the corresponding terminal according to the primary number information. When the short message is terminated in a card number service, no major modification is needed on the SMSC and the HLR, which reduces the cost of service maintenance and upgrade.

In an embodiment of the present invention, the SCP registers the address information of the SCP as the home location information of the secondary number in the home location register HLR as a step of the secondary number account opening procedure, and immediately after assigning the secondary number to the secondary number The secondary number is updated. The SCP simulates the MSC (Mobile Switching Center)/VLR (Visitor Location Register), and in turn initiates location registration for each secondary number to the HLR, the operation including the IMSI of the secondary number (International Mobile Subscriber Identification) Number, International Mobile Subscriber Identity (denoted as S-IMSI) and SCP's GT code (Global Title), where the SCP's GT code is updated to the HLR as the MSC/VLR address. 2 is a flowchart of a secondary number location update according to an embodiment of the present invention. As shown in FIG. 2, the method includes the following steps:

S202. The SCP carries a GT code to send a location update request to the HLR.

S204: After receiving the location update request, the HLR writes the log if the location information is successfully registered, and the process ends.

S206. If the HLR does not respond and the final response fails, the log is written, and the process ends.

S208: If the HLR does not respond, but the SCP receives the ISD (Insert Subscriber Data) request and processes normally, the operation returns to the HLR and waits for the final response of the HLR. If the HLR successfully registers the location information, the log is written. End.

S210: If the HLR does not respond and the final response fails, the log is written, and the process ends.

In the case that the final response fails in the above steps, the location update operation may be initiated again. Of course, the location update process may be performed periodically or in batches.

In one embodiment of the invention, the location update operation can be initiated by the interface machine on a daily basis. By scanning the secondary number information on the storage module, the location update of all secondary numbers is initiated in batches, and the update time and update interval can be configured. For the case where the location registration fails, the location update operation may be initiated in batches by the interface machine.

FIG. 3 is a flowchart of a secondary number location update signaling according to an embodiment of the present invention. As shown in FIG. 3, in an embodiment of the present invention, an UpdateLocation (Location Update Request) initiated by an SCP needs to carry a secondary number IMSI (S- IMSI), home location information (MSC-id, VLR-id), where the home location information is the GT code of the SCP. The InsertSubData (ISD) message of the HLR response carries various attributes of the secondary number, such as IMSI (S-IMSI), MSISDN (S-MSISDN), and protocol version (CamelPhase) of the secondary number. After receiving the ISD, the SCP can use each attribute of the secondary number according to actual needs, and respond to the HLR with a successful InsertSubData-ACK (ACK is Acknowledgment, confirmation). After receiving the successful ISD-ACK, the HLR responds to the SCP with an UpdateLocation-ACK. So far, the location information of the secondary number on the HLR has been successfully updated to the GT code of the SCP.

In an embodiment of the present invention, after the location information of the secondary number is updated, the SMSC sends the short message to the GMSC (Gateway Mobile Switching Center) according to the called number. FIG. 4 is an embodiment according to the present invention. The short message termination call signaling flowchart is as shown in FIG. 4, and the method includes the following steps:

S402: The GMSC sends an SRI-SM (Send rout information for SMS) to the HLR to query the location information of the secondary number, and obtains the GT whose home location is the SCP.

S404: The GMSC routes the short message to the SCP through the MTForwardSM (Mobile Terminated Forward SM), and the SCP receives the short message, and extracts the calling number (UI: Calling number) and the called number (DA: S-MSISDN). Information such as the SMSC address (OA: SMSC), wherein the called number is a secondary number; the SCP queries the database for the primary number and the secondary number corresponding to the secondary number.

S406: The SCP sends the SRI-SM to the HLR to query the location information of the primary number, to obtain the real MSC address of the primary number.

S408: The SCP forwards the MT Forward SM to the MSC of the primary number, where the calling format is: a route prefix + a calling number, and the called party is a primary number.

S410. After forwarding, the SCP returns a successful response to the GMSC, and the process ends.

In an embodiment of the present invention, a route prefix may be added before the calling number, so that the called user can know which secondary number is currently used after receiving the short message. As shown in FIG. 4, the routing prefixes RN1 to RN5 can be respectively configured to correspond to the five sub-numbers of the user. When the calling number of the short message is RN3 plus the number, the short message can be judged to be the third. The secondary number is received. It is also possible to determine which secondary number the user is currently using by specifying the activation number.

In an embodiment of the present invention, the correspondence information between the secondary number and the primary number and the secondary number prefix information may be stored in the database of the intelligent network system, and the status information of the primary and secondary numbers may also be stored and managed, such as account blocking, Virtual switch machine, etc.; SCP can respond differently to different states according to actual needs.
