PCC Redirection for Service Status Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Policy and Charging Control (PCC) architectures lack the ability to timely notify users of their service status, particularly for users with data cards and no mobile phones, limiting their service experience.
Innovation Solution
A redirection method and apparatus under PCC that acquires user service status change information and current scenario data, determines if a redirection task is needed, generates a redirection indication message, and sends it to the Policy and Charging Enforcement Function (PCEF) or Policy and Charging Rule Function (PCRF) to perform a redirection operation, allowing users to receive real-time service usage details via HTTP webpages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the prior art uses SMS notification for service status, then users with mobile phones can be notified, but users with data cards and no mobile phones cannot be notified
Solution Approach 1:
The patent introduces an HTTP webpage as an intermediary notification medium. Instead of directly notifying users via SMS (which requires a mobile phone), the system redirects users to an HTTP webpage that displays service status information. This intermediary approach allows users with data cards but no mobile phones to receive notifications through web browsers, thereby expanding notification coverage to include users who cannot receive SMS.
2Adaptability or versatility
If the system redirects to HTTP webpage for service status notification, then users without SMS capabilities can be notified, but the notification timeliness may be affected
Solution Approach 1:
The patent implements preliminary action by pre-configuring redirection policies in the PCEF that automatically redirect users to appropriate notification channels based on their device capabilities. When a user accesses a service, the system proactively determines the user's notification capability and redirects them to an HTTP webpage in advance, ensuring that service status information is available when the user needs it, thereby minimizing notification delays.

AI summary
The present invention relates to the field of communication technology. Disclosed are a redirection method and a redirection apparatus under policy and charging control (PCC) for improving user's service experience. The redirection method under PCC comprises: acquiring a user's service status change information and the current scenario information; determining whether to issue a redirection task to a policy and charging enforcement function (PCEF) according to the current scenario information; when a redirection task needs to be issued to the PCEF, then generating a redirection indication message according to the service status change information and the current scenario information, the redirection indication message comprising redirection indication information; and sending the redirection indication message to the PCEF so that the PCEF performs a redirection operation according to the redirection indication information in the redirection indication message.
