Embodiment 1

[0040] The present invention has adopted Factors of NFs local cache NRF (network resource management function entity) discovery result and uses hash address mapping table (also claiming cache mapping table) H (addr) The way Table maps the address information of peer NFs avoids NFs from repeatedly querying NRF, improves the efficiency of mutual discovery of NFs, and provides a way to dynamically modify configuration files on NFs according to network deployment needs, allowing network administrators to use the least Cost to change the Factors of a certain NF cache.

[0041] A method of accelerating the mutual discovery of NFs in the 5G core network of the present invention, such as figure 1 shown, including the following steps:

[0042] Step S1. When the NF needs to communicate with the peer NF, the NF decodes the data from the message triggering the communication process or obtains the peer NF type and reference factors Factors from the data stored in the NF.

[0043] Step S...

Abstract

The invention provides a method for accelerating mutual discovery of NFs in a 5G core network. A reference factor of an NRF discovery result is locally cached by NFs, and the position and state information of an opposite end NF is mapped by using a cache mapping table. According to the method, the NFs are prevented from repeatedly querying the NRF; the mutual discovery efficiency of the NFs is improved; and a mode of dynamically modifying configuration files on the NFs according to the network deployment requirement is provided, so that a network administrator can change the reference factor of a certain NF cache at the minimum cost.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for accelerating mutual discovery of NFs in a 5G core network. Background technique [0002] In the 5G core network (abbreviation: 5GC) based on the service architecture SBA, network element functions are subdivided, and more network function entities NFs are evolved. If NFs need to communicate with each other, they first need to go through the process of mutual discovery and selection. As defined in the R15 and R16 versions of the 3GPP protocol TS23501-g30, there are two ways for NFs to discover each other: local acquisition and NRF discovery (abbreviation: local acquisition and NRF discovery). Among the two discovery methods, the local acquisition usually adopts the method of writing the peer NF address information in a static configuration file. If the NRF discovery method is used, different reference factor Factors (such as DNN, S-NSSAI, etc.) need to b...
