example 1

[0157] When the user equipment UE attaches through the 5GC, the 5GC network element writes the currently attached core network type information (5GC) into the UDM / HSS.

[0158] When the IMS UE performs IMS registration, the UDM / HSS sends the information of the current attached core network type (5GC) to the S-CSCF, and the S-CSCF carries the information in the registration response and sends it to the P-CSCF, and the P-CSCF according to This information determines whether the user is attached to the 5GC. If the P-CSCF receives the attached core network type information, it can know that the UE is currently attached to the 5GC, and determine how to route the diameter message. Find the address of the DRA corresponding to the UE, send the diameter message to the DRA through the Rx interface, or find the address of the BSF corresponding to the UE through addressing, and send the diameter message to the BSF through the Nx interface.

[0159] For example, the methods provided by thi...

example 2

[0170] This example proposes a method for how the Application Function (Application Function, AF) judges the correct routing of the diameter message according to the user access core network information when the DRA and the BSF coexist, including:

[0171] When the user equipment is attached from the 5GC, the 5GC writes the current attached core network type (5GC) to the UDM / HSS. There are three implementation methods for this process

[0172] SMF writes in UDM / HSS that the currently attached core network type is 5GC;

[0173] PCF writes in UDM / HSS that the currently attached core network type is 5GC;

[0174] AMF writes in UDM / HSS that the current attached core network type is 5GC;

[0175] When the IMS UE performs IMS registration, when the S-CSCF obtains the user subscription data from the HSS, the UDM sends the diameter message of the user's current attached core network type (5GC) to the S-CSCF through the Cx interface

[0176] The S-CSCF carries the information of the ...

Abstract

The embodiment of the invention provides an information processing method and device, a communication network element and a storage medium. The information processing method applied to a proxy call session control function (P-CSCF) can comprise the following steps: receiving attached core network type information of user equipment (UE) from a serving call session control function (S-CSCF); and according to the type information of the attached core network, selecting a corresponding interface to carry out diameter message routing.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to an information processing method and device, a communication network element and a storage medium. Background technique [0002] The diameter message is transmitted based on the diameter protocol. The diameter protocol supports mobile network protocol (Internet Protocol, IP), non-access stratum (Non Access stratum, NAS) request and mobile agent authentication, authorization and accounting. Value pairs (in the form of Attribute-Length-Value triples). In the prior art, it is often found that diameter messages are routed incorrectly or cannot be routed. Contents of the invention [0003] In view of this, the embodiments of the present invention expect to provide an information processing method and device, a communication network element, and a storage medium, at least partially solving the above-mentioned problem that the diameter message cannot be correctly ro...
