Example Embodiment

[0050] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0051] Such as figure 1 As shown, the short message routing method of the embodiment of the present invention, applied to the IP-SM-GW, includes:

[0052] Step 101: Obtain a registration request message of a UE, and the registration request message includes slice information currently accessed by the UE.

[0053] Specifically, in this step, when UE registers with IMS (IP Multimedia Subsystem), it will obtain NSSAI (network slice selection assistance information) information (network slice selection assistance information) obtained in the 5G core network registration process ( The S-NSSAI (Single Network Slice Selection Assistance Information) related to SMS is carried in the IMS registration request and sent to the S-CSCF. The S-CSCF sends the NSSAI information to the IP during the three-party registration -SM-GW.

[0054] Wherein, the slice information that the UE currently accesses refers to the identifier of the slice that provides the short message service for the UE when the UE is currently registered.

[0055] Step 102: When the downlink short message fails to be delivered through the IP multimedia subsystem, determine the routing information of the downlink short message according to the slice information currently accessed by the UE, and deliver the downlink short message according to the routing information .

[0056] Specifically, in this step, the IP-SM-GW maps out the GT (Globe Title, Global Marking Code) address corresponding to the UDM in the slice currently accessed by the UE according to the slice information currently accessed by the UE. Perform a called location query to the UDM according to the GT address, and send the downlink short message to the SMSF in the slice currently accessed by the UE according to the called location query result.

[0057] For example, in practical applications, the IP-SM-GW may obtain the preset mapping relationship, and map out the UDM corresponding to the slice currently accessed by the UE according to the slice information currently accessed by the UE and the mapping relationship. The GT address. Wherein, the mapping relationship may be a correspondence relationship between slice information and GT addresses, etc.

[0058] In the embodiment of the present invention, when a downlink short message fails to be delivered through the IP multimedia subsystem, the routing information of the downlink short message can be determined according to the current slice information of the UE in the registration request message of the UE. And send the downlink short message according to the routing information. Therefore, using the solution of the embodiment of the present invention can ensure that SMSoIP can implement correct routing of downlink short messages in a multi-slice deployment environment.

[0059] Such as figure 2 As shown, the short message routing method of the embodiment of the present invention, applied to the UE, includes:

[0060] Step 201: Send a registration request message. The registration request message includes slice information currently accessed by the UE, so that when the downlink short message fails to be delivered through the IP multimedia subsystem, the IP-SM-GW will The accessed slice information determines routing information of the downlink short message, and delivers the downlink short message according to the routing information.

[0061] Specifically, in this step, when the UE performs IMS registration, the NSSAI information (including S-NSSAI information related to SMS) obtained through the 5G core network registration process is carried in the IMS registration request and sent to the S- CSCF. The S-CSCF sends the NSSAI information to the IP-SM-GW when performing three-party registration.

[0062] Wherein, the slice information that the UE currently accesses refers to the identifier of the slice that provides the short message service for the UE when the UE is currently registered.

[0063] Step 202: Receive the downlink short message.

[0064] In the embodiment of the present invention, when a downlink short message fails to be delivered through the IP multimedia subsystem, the routing information of the downlink short message can be determined according to the current slice information of the UE in the registration request message of the UE.

[0067] Step 302: When the UE performs the IMS registration, the NSSAI information (including S-NSSAI information related to the short message) obtained through the 5G core network registration process is carried in the IMS registration request (Register).

[0068] Step 303: The S-CSCF sends the NSSAI information to the IP-SM-GW when performing three-party registration.

[0069] Step 304: The IP-SM-GW stores the S-NSSAI information related to the short message, that is, the slice identifier that provides the short message service for the current registration of the UE.

[0070] Step 305: When the delivery of the MT short message through the IMS fails, the IP-SM-GW maps the stored S-NSSAI information of the UE through a specific mapping method to map out the GT code address corresponding to the UDM in the slice.

[0071] The IP-SM-GW performs the called location query to the UDM through the mapped GT code, and then sends the MT short message to the SMSF in the slice to complete the correct routing of the downlink short message.

[0072] For example, in practical applications, the IP-SM-GW may obtain the preset mapping relationship, and map out the UDM corresponding to the slice currently accessed by the UE according to the slice information currently accessed by the UE and the mapping relationship. The GT address. Wherein, the mapping relationship may be a correspondence relationship between slice information and GT addresses, etc.
