[0029] USSD (Unstructured Supplementary Service Data) notification messages can flexibly and conveniently send content in various formats, such as billing information, welcome text messages, etc. Currently, users are registered in the CS (Circuit Switched) domain, and USSD notification messages are sent to users through the CS network.

[0030] As network architecture evolves, more and more users are registered only in the IMS (IP Multimedia Subsystem) domain. At this time, it is impossible to send USSD notification information to users registered in the IMS domain in real time.

[0031] In the disclosed embodiment, the SSS (Switching Sub-system) address of the registered IMS domain is pre-recorded in the HLR (Home Location Register), and after the user completes the preset service, the HLR performs domain selection on the USSD (Unstructured Supplementary Service Data) notification message sent by the USSDC (Unstructured Supplementary Service Data Centre), and the SSS delivers the USSD notification message to the domain where the user is located, so that the USSD notification message can be received in time when the user registers in the IMS domain, so that all users can timely grasp the USSD notification message pushed by the operator, the user side can feel the consistency and real-time nature of the USSD service experience, and the user experience is enhanced; the operator side can ensure that the operator's notification message can be pushed to the user side in time, thereby increasing related business revenue.

[0032] The USSD notification sending method of the embodiment of the present disclosure can be executed by any electronic device that needs to execute USSD notification sending, such as a terminal device or a server. The terminal device may include but is not limited to: vehicle-mounted equipment, user equipment (User Equipment, UE), mobile equipment, computing equipment, wearable devices, etc., for example, including but not limited to cellular phones, cordless phones, personal digital assistants (Personal Digital Assistant, PDA), portable computers, etc. The USSD notification sending method can be implemented by a processor calling a computer-readable program instruction stored in a memory, or it can be implemented by a server.

[0033] The following is a detailed introduction to the embodiments of the present disclosure.

[0034] The present disclosure provides a method for sending a USSD notification. Figure 1 As shown, the method may include steps S11-S14:

[0035] S11. USSDC delivers the service information of the preset service to HLR through a USSD notification message; the HLR pre-records the SSS address of the registered IMS domain.

[0036] In the disclosed embodiment, the preset service may include but is not limited to call service and preferential activity service of the operator; the service information may include but is not limited to billing information, welcome information, preferential policy information, etc.

[0037] In the embodiment of the present disclosure, before the unstructured supplementary data service center USSDC delivers the service information of the preset service to the home location register HLR through the unstructured supplementary data service USSD notification message, the method may further include:

[0038] When the user registers in the IMS domain, the host name of the SSS is mapped to the global tag GT of the host device, and the GT is sent to the HLR, and the HLR saves the SSS address of the SSS according to the GT.

[0039] In the embodiment of the present disclosure, the GT (Global Title) of the host device refers to the GT number of the host device, which is a label used to identify a message path in a mobile network.

[0040] In the embodiment of the present disclosure, when a user registers in the IMS domain, the host name of the SSS is mapped to the global tag GT of the host device, and the GT is sent to the HLR, and the HLR saves the SSS address of the SSS according to the device GT, which may include:

[0041] When a user registers with IMS, CSCF (Call Session Control Function) notifies SSS to initiate third-party registration.

[0042] SSS subscribes to and downloads the user's user information from HSS (Home Subscriber Server);

[0043] IMS HSS maps the host name of SSS into the GT of the host device and transmits the GT to HLR through an internal message. HLR saves the SSS address corresponding to the preset service according to the device GT.

[0044] In the embodiments of the present disclosure, Figure 2As shown, both HSS and HLR belong to USPP (Universal Subscriber Profile Platform). After receiving the REGISTER information of the user registered in the IMS domain, the service S-CSCF (Service-Call Session Control Function) in CSCF downloads the user agreement (User Profile Downloading) to the HSS in USPP. The S-CSCF sends the REGISTER information to the SSS. The SSS (including the unstructured supplementary data service gateway USSD GW) subscribes to and downloads the user information from the HSS through the SNR (Sh-subs Notifrequest). According to the SNR, the HSS maps the hostname of the SSS to the GT of the host device, and passes the SSS address to the HLR in USPP through an internal message. The HLR saves the SSS address corresponding to the user executing the preset service (for example, voice call VoLTE), and the HSS returns the Sh-subs Notif Respond (user data subscription notification response) information to the SSS for the SNR.

[0045] S12. After receiving the USSD notification message, the HLR performs domain selection on the USSD notification message.

[0046] In the embodiment of the present disclosure, after receiving the USSD notification message, the HLR performs domain selection on the USSD notification message, including:

[0047] Detect the domain registered by the user of the preset service corresponding to the USSD notification message.

[0048] In the embodiments of the present disclosure, for example, Figure 3 As shown, after the user completes the call, USSDC sends an Unstructured ssNotify message, i.e., a USSD notification message, to the HLR. After receiving the USSD notification message, the HLR performs domain selection for the VoLTE user according to the registration status. For example, if the IMS domain is registered, the IMS domain is selected; if the CS domain is registered, the CS domain is selected; if dual registration is performed in the IMS domain and the CS domain, the IMS domain and the CS domain are selected.

[0049] S13. When the domain selection result includes the IMS domain, send a USSD notification message to the SSS.

[0050] In an embodiment of the present disclosure, when the domain selection result includes the IMS domain, sending the USSD notification message to the SSS includes:

[0051] When the user registers in the IMS domain, or the user performs dual registration in the IMS domain and the CS domain, the SSS corresponding to the preset service is determined according to the recorded SSS address, and the USSD notification message is sent to the SSS.

[0052] In the embodiments of the present disclosure, Figure 3 As shown, HLR performs service domain selection (referred to as domain selection) for VoLTE users. If the user has registered in the IMS domain, the USSD notification message is delivered to the SSS; if the user is dual-registered in the CS domain and the IMS domain, the USSD notification message is also delivered to the SSS. Among them, HLR sends a Map_Process_Unstructured_ss_Notify_Req (processing unstructured supplementary service request) message to the SSS, so that the SSS delivers the USSD notification message according to the domain selection result contained in the Map_Process_Unstructured_ss_Notify_Rep message.

[0053] S14. The SSS determines the domain where the user is currently located, and delivers a USSD notification message to the domain where the user is located.

[0054] In the embodiment of the present disclosure, the SSS determines the domain where the user is currently located, and delivers a USSD notification message to the domain where the user is located, including:

[0055] When the user is registered in the IMS domain, the SSS delivers the USSD notification message to the IMS network;

[0056] When a user performs dual registration in the IMS domain and the CS domain, the SSS delivers a USSD notification message to the IMS network and delivers the USSD notification message to the mobile switching center MSC or the visitor location register VLR.

[0057] In the embodiment of the present disclosure, if the user is registered in the IMS domain, it can be determined that the USSD notification message needs to be delivered to the IMS network; if the user is registered in the CS domain, it can be determined that the USSD notification message needs to be delivered to the CS network (e.g., delivered to the MSC / VLR). If dual registration is performed in the IMS domain and the CS domain, the USSD notification message needs to be delivered to the IMS network and the CS network respectively.

[0058] In the embodiment of the present disclosure, the SSS delivers a USSD notification message to the IMS network, including:

[0059] The SSS converts the USSD notification message into a SIP (Session Initiation Protocol) message, and delivers it to the CSCF via an Invite (session establishment invitation) message. The CSCF then completes the delivery of the USSD notification message to the IMS network.

[0060] The USSD notification message is a type of USSD MAP (Unstructured Supplementary Data Service Mobile Application Part) message.

[0061] In the embodiments of the present disclosure, Figure 3 As shown, the SSS sends an Invite<USSD> message (a session establishment invitation containing a USSD notification message) to the S-CSCF, and the S-CSCF completes the delivery of the USSD notification message to the IMS network according to the Invite<USSD> message; the S-CSCF can deliver the USSD notification message to the user (UE) through the IMS network when the user registers for the IMS domain alone, and the S-CSCF can deliver the USSD notification message to the user (UE) through the IMS network and the CS network when the user registers for the IMS domain and the CS domain.

[0062] In the embodiment of the present disclosure, after performing domain selection on the USSD notification message, the method may further include:

[0063] In the case where the user is registered in the CS domain only, the USSD notification message is sent to the MSC (Mobile Switching Center) or the VLR (Visitor Location Register).

[0064] In the embodiments of the present disclosure, Figure 3 As shown, the SSS sends a Map_Process_Unstructured_ss_Notify_Rep message to the MSC / VLR to implement delivery of the USSD notification message.

[0065] In the embodiment of the present disclosure, after the SSS determines the domain where the user is currently located and delivers the USSD notification message to the domain where the user is located, the method may further include:

[0066] The SSS receives the first delivery response information returned by the IMS network and / or the CS network, and returns the second delivery response information to the HLR according to the first delivery response information;

[0067] The HLR returns third delivery response information to the USSDC according to the second delivery response information.

[0068] In the embodiments of the present disclosure, Figure 3As shown, SSS sends a Map_Process_Unstructured_ss_Notify_Rsp (process unstructured supplementary service response) message to HLR, that is, the second delivery response information; HLR sends an Unstructured ss Notify ack (unstructured supplementary service notification answer) message to USSD, that is, the third delivery response information.

[0069] Through the solution of the embodiments of the present disclosure, users registered in different domains can experience the consistency and real-time performance of USSD service, thereby enhancing the user experience; operators can ensure that their notification messages can be pushed to the user side in a timely manner, thereby increasing related business revenue.
