Embodiment Construction

[0090] The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations.

[0091] The terms "first" and "second" in the description and claims of the embodiments of the present invention are used to distinguish different objects, rather than to describe a specific sequence of objects. For example, a first processor, a second processor, etc. are used to distinguish different processors, not to describe a specific order of the processors.

[0092] In the embodiments of the present invention, words such as "exemplary" or "for example" are used as examples, illustrations or illustrations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present invention shall not be construed as being more preferred or more advantag...

Abstract

The embodiment of the present invention provides a routing addressing method, short message downlink processing method, device and system, the method includes: after receiving the SMSF registration message, sending a notification request or a registration request to the user's home SMSC, the notification request or The registration request includes UDM information; after receiving the called route query request from the user's home SMSC, the SMSF information is returned to the user's home SMSC; wherein, the called route query request is sent to the user's home SMSC according to the UDM information stored by the user's home SMSC. sent by UDM. In this way, the SMSC does not need to query the user number segment to address the UDM based on the called number, but only needs to perform routing according to the determined UDM information to find the destination node.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a routing addressing method, a short message downlink processing method, equipment and a system. Background technique [0002] see figure 1 , network slicing (hereinafter referred to as slicing) is a set of end-to-end logical functions and the required physical or virtual resources, including access network, core network functions, etc., and even backhaul network and IP (Internet Protocol, Internet Protocol) network With collaborative support, slices can be considered as a virtualized "private network" in a 5G (Fifth-generation, fifth-generation mobile communication technology) network. [0003] Basic process of 5G short message: registration, sending and receiving SMS (Short Messaging Service, short message service) process. [0004] (1) Registration process [0005] The AMF (Access and Mobility Management Function) decides to select a Short Message Service Function SMS...
