A short message routing method, device, equipment and computer-readable storage medium

Abstract

The invention provides a short message routing method, device, equipment and computer-readable storage medium, which relate to the field of communication technology and are used to ensure that SMSoIP can realize the correct routing of downlink short messages in the environment of multi-slice deployment. The short message routing method of the present invention includes: obtaining a registration request message of a user equipment UE, and including slice information currently accessed by the UE in the registration request message; 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. The invention can ensure that the SMSoIP can realize the correct routing of downlink short messages in the environment of multi-slicing deployment.

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...

AI Technical Summary

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.
