Problems solved by technology

[0009] When the UE is dynamically attached to different slices, the IP-SM-GW cannot select the MAP signaling connection through the user number segment information, and at the same time cannot know the slice where the user is located, so it cannot correctly select the MAP signaling connection to the UDM where the user is located. As a result, the routing of downlink short messages fails.

Embodiment Construction

[0050] The specific implementation manner of the present invention will be further described in detail below with reference to the drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended 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 is applied to IP-SM-GW, including:

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

[0053]Specifically, in this step, when the UE performs IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) registration, the NSSAI (network slice selection assistance information, network slice selection assistance information) information ( It includes SMS-related S-NSSAI (SingleNetwork Slice Selection Assistance Information, single network slice selection assistance informatio...

Abstract

The invention provides a short message routing method, a short message routing device, short message routing equipment and a computer readable storage medium, relates to the technical field of communication, and is used for ensuring that an SMSoIP can realize correct routing of a downlink short message in a multi-slice deployment environment. The short message routing method comprises the following steps: acquiring a registration request message of user equipment (UE), wherein the registration request message comprises slice information currently accessed by the UE; And when the downlink shortmessage fails to be issued through the IP multimedia subsystem, determining the routing information of the downlink short message according to the slice information currently accessed by the UE, andissuing the downlink short message according to the routing information. According to the invention, it can be ensured that the SMSoIP can realize correct routing of the downlink short message in a multi-slice deployment environment.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a short message routing method, device, equipment and computer-readable storage medium. Background technique [0002] The concept of network slicing is introduced in the 5G network. Network slicing is a collection of end-to-end logical functions and the required physical or virtual resources, including access network, core network functions, etc., and even needs the collaborative support of backhaul network and IP network. Network slicing can be considered as a 5G network virtualized "private network". [0003] The basic flow of short messages in the 5G network is as follows: [0004] 1) In the UE (User Equipment, user equipment) registration process, the AMF (Access and MobilityManagement Function, access and mobility management function) decides to select the A SMSF (SMS Function, SMS function); [0005] 2) AMF activates SMS (Short Message Service, Short Mess...
