Intelligent Service Policy Rule Provisioning for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunication systems face congestion due to excessive signaling between policy decision points (PDPs) and policy enforcement points (PEPs) as they provision and enforce service policy rules for client devices, leading to inefficient network operations.
Innovation Solution
The method involves evaluating the extent to which service policy rules have been applied for a client device and provisioning only the subset of rules that have been applied to a threshold extent, reducing the number of rules sent from the PDP to the PEP, thereby minimizing unnecessary signaling and congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the PDP provisions the PEP with all service policy rules for a client device, then the PEP can enforce complete service policy compliance, but excessive signaling occurs between PDP and PEP causing network congestion
Solution Approach 1:
The patent extracts only the necessary service policy rules from the complete set and provisions them selectively to the PEP. The PDP identifies and provisions only those rules that are actually applicable to each client device based on their service profile and current service context, rather than provisioning all possible rules. This extraction approach maintains policy compliance while reducing signaling overhead.
Solution Approach 2:
The patent segments the complete service policy rule set into individual rules and provisions them separately to the PEP based on applicability. Instead of treating the service policy as a monolithic block, the system evaluates and provisions specific rules individually, allowing the PEP to enforce only the relevant subset of policies for each client device.
2Reliability
If the PDP provisions the PEP with a complete service profile, then all service policy rules are available for enforcement, but the amount of data transmitted increases signaling overhead
Solution Approach 1:
The patent extracts only the essential service policy rules from the complete service profile and transmits them to the PEP. The PDP analyzes the client device's service profile and extracts only those rules that are currently applicable, thereby reducing the volume of signaling data while ensuring complete policy enforcement for the relevant rules.
3Reliability
If the PEP enforces all possible service policy rules, then service compliance is ensured, but processing overhead at the PEP increases
Solution Approach 1:
The patent extracts and provisions only the applicable service policy rules to the PEP, eliminating the need for the PEP to process and evaluate all possible rules. This extraction approach maintains service compliance by ensuring all relevant rules are enforced while reducing the PEP's processing burden by removing irrelevant rules from consideration.

AI summary
A method and corresponding system to help facilitate the application of service policy rules for client devices while reducing the amount of signaling between network entities is disclosed. In accordance with one example, the wireless network may evaluate the extent to which the service policy rules defined by the UE's service profile have been applied by the wireless network. Based on this evaluating, the network may identify a subset of service policy rules that have been applied to greater than a threshold extent by the network for the given UE. And in response to this identifying, the network may cause the PDP to provision the PEP, with the subset of service policy rules, rather than provision the PEP with every possible service policy rule. As a result, the PDP and PEP may refrain from engaging in excess signaling, and the wireless network, in turn, may enjoy reduced congestion.
