AI Technical Summary

Technical Problem

Existing fallback solutions for user equipment (UE) connecting to older generation networks are time-consuming, unreliable, and do not provide optimal services due to inefficient authentication and verification processes.

Method used

A method and system that utilize a Policy and Charging Rules Function (PCRF) to trigger a service request towards an Online Charging System (OCS), extract attributes, evaluate policies, and connect the UE to a fallback network based on evaluated policies, even when subscriber profiles are unavailable.

Benefits of technology

This approach ensures seamless service continuity by maintaining connections even when subscriber profile information is temporarily inaccessible, enhancing user experience and optimizing network performance and resource allocation.

Abstract

The disclosure relates to a system (108) and a method (500) for connecting a user equipment (UE) (104) from a first network (106) to a second network (110). The method (500) receive (502), at the second network (110), a request associated with the UE (104) from the first network (106), and triggers (504), by a policy and charging rules function (PCRF) (306), a service request towards an online charging system (OCS) (310) based on the received request. The method (500) receives (506) a response message at the PCRF (306) based on the triggered service request and extracts (508) attributes associated with the response message. The method (500) evaluates (510) one or more policies based on determining that the extracted attributes meet at least one condition defined on a policy rule engine and connecting (512) the UE (104) to the second network (110) based on the one or more evaluated policies.
