PCRF PCC Rule Processing via IP Stream Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The Policy and Charging Control (PCC) rule in the 3GPP EPS system cannot be effectively modified by the Policy and Charging Rules Function (PCRF), leading to limitations in dynamic network resource allocation and service optimization.
Innovation Solution
A method and apparatus that allow the PCRF to process PCC rules by receiving IP flow mapping information from a User Equipment (UE), determining the necessary routing rule information, and sending it to the PCRF to update or modify PCC rules, enabling dynamic access network type changes and filter management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the PCRF cannot modify PCC rules in the existing system, then the system architecture remains simple and stable, but dynamic network resource allocation and service optimization are limited
Solution Approach 1:
The patent introduces routing rule information as an intermediary carrier that bridges the UE and PCRF. This routing rule information contains PCC rule identifiers and filter identifiers, enabling the PCRF to indirectly access and modify PCC rules without requiring direct exposure of the complex PCC rule structure, thus resolving the contradiction between adaptability and complexity
Solution Approach 2:
The patent establishes preliminary routing rule information that pre-identifies PCC rule identifiers and filter identifiers before modification operations. This preliminary structuring of identification data enables the PCRF to efficiently locate and modify specific PCC rules without parsing entire rule sets, achieving dynamic allocation while controlling processing complexity
2Reliability
If the PCRF processes PCC rules with multiple filters, then comprehensive service control is achieved, but the processing complexity and time increase
Solution Approach 1:
The patent segments the PCC rule processing by introducing filter identifiers as independent reference points. Each filter can be individually identified and modified through the routing rule information, allowing the PCRF to process only specific filter segments rather than entire PCC rules, thus maintaining comprehensive control while reducing processing time
Solution Approach 2:
The patent creates a simplified copy of PCC rule identification information in the routing rule structure. This copy contains essential identifiers (PCC rule identifier, filter identifier) that reference the actual PCC rules, enabling the PCRF to work with lightweight identifier copies instead of complex rule structures, achieving both completeness and efficiency
3Adaptability or versatility
If the system supports multiple access networks (3GPP and non-3GPP), then network versatility is improved, but the complexity of access network type management increases
Solution Approach 1:
The patent creates a universal routing rule information structure that can identify and manage PCC rules across different access network types (3GPP and non-3GPP). The standardized identifier format and processing mechanism work uniformly across all access types, enabling multi-network support without proportionally increasing management complexity
Data Source
AI summary
Provided herein are a method and device for processing a PCC rule. The method comprises: receiving first internet protocol (IP) stream mapping information transmitted by a UE and used for requesting the processing of an IP stream; determining, on the basis of the first IP stream mapping information, first routing rule information comprising a first PCC rule identification of a first PCC rule corresponding to the IP stream or first filter identifier of a first filter corresponding to the IP stream, where the first filter is a filter that the first PCC rule comprises; transmitting the first routing rule information to a policy and charging rules function entity (PCRF), thus instructing the PCRF to process the first PCC rule according to the first routing rule information.
