Tailoring Control to Individual Needs

Every child is unique, and their online needs and activities can vary widely based on age, interests, and developmental stages. That's where personalized service policies come into play. Instead of applying one-size-fits-all restrictions, parents can now customize control settings to align with each child's specific requirements.

Empowering Network-Based Parental Control with Dynamic Policy Controlling

In the realm of network-based parental control, the Policy & Charging Rules Function (PCRF) or Policy Control Function (PCF) emerges as a powerful ally, enabling telecom operators to implement robust parental control policies that align with the diverse needs of families. Here's how VizuaMatix Policy Controller (vxPCRF) plays a pivotal role in implementing these policies:

1. Customized Parental Control Policies

vxPCRF empowers telecom operators to define and enforce highly customized parental control policies tailored to individual households. From granular controls to dynamic adjustments, here's how vxPCRF supports this:

Granularity: vxPCRF allows operators to create finely tuned policies that consider factors like age groups, content preferences, and time of day. For example, parents can set stricter controls for younger children while allowing more flexibility for teenagers.

Dynamic Policy Updates: As children grow and their online needs evolve, vxPCRF enables dynamic policy updates. Parents can easily adjust controls in real-time, ensuring that parental control policies remain aligned with their family's changing requirements.

Content Filtering: vxPCRF can enforce content filtering policies to block access to age-inappropriate or harmful content. These policies can be customized to align with parental guidelines.

2. Time-Based Control Policies

Sliding window policy control is especially crucial in parental control scenarios to manage screen time effectively. vxPCRF facilitates this in several ways:

Screen Time Limits: vxPCRF can shape screen time by applying policies that restrict the amount of time children can spend online during specific hours or within a sliding window. For instance, parents can set bedtime controls to ensure children disconnect from devices at night.

Homework Hours: During designated "homework hours," vxPCRF can automatically prioritize educational websites and applications while restricting access to gaming and entertainment platforms.

Notifications: vxPCRF can send notifications to parents when predefined time limits are reached, ensuring that they are informed about their children's online activities.

Usage Monitoring: vxPCRF monitors and logs children's online usage within sliding windows. This data helps parents understand their children's digital habits and make informed decisions about their online activities.

Technical challenges to overcome in network-based personalized control

Implementing complex granular-level personalized service-based policies with sliding window-based policy control can indeed be challenging, especially when striving to strike a balance between space and time complexity. In the realm of parental control, where policies are unique to each user, and multiple services are influenced by the day of the week and time of day rules, managing these diverse combinations efficiently is paramount.

The Challenge

Policy Diversity: With each user having their unique set of preferences and requirements, and numerous services to consider, the policy landscape becomes incredibly diverse. This requires a sophisticated system capable of handling countless policy permutations.

Real-Time Processing: In parental control, real-time policy enforcement is crucial to ensure that children are protected online. Delayed responses or lags in policy execution can compromise the effectiveness of the control system.
