What is the difference between PCC and SCC 5G?

5G

In the Context of 5G (Fifth Generation) Wireless Networks, The Terms "PCC" (Policy and Charging Control) and "SCC" (Session and continuity control) Return to Distinct Elements that play crucial roles in Network Management and Control. Here's a detailed explanation of the differentes between pcc and SCC in the context of 5g:

  1. PCC (Policy and Charging Control):
    • Definition:
      • PCC Stands for Policy and Charging Control. It is a functional element in 5g networks that combines police control and charging control to manage and control data sessions based on policy rules and charging police.
    • Key Functions:
      • Policy Control: PCC is responsible for Enforcing Policies that define HowWork Resources Are Allocated to User Sessions. These Policies May Include Prioritization of Certain Types of Traffic, Quality of Service (QOS) Parameters, and Other Service-Specific Rules.
      • Charging Control: PCC Also Handles Charging-Related Functions, Determining How User Sessions Are Browed On Factors Such As Data Usage, Service Type, and Other Charging Policies.
    • Integration with Other Network Elements:
      • PCC Integrats With Various Network Elements to Enforce Policies and Charging Rules, Ensuring That User Sessions Align With Service-Specific Criteria.
    • Example scenario:
      • In A 5G Network, PCC COULD ENLD Policies that prioritize video streaming traffic, Higher Bandwidth to specific Applications, or Apple Charging Rules Based On Data Consumption for Different Service Plans.
  2. SCC (Session and Continuity Control):
    • Definition:
      • SCC stands for session and continuity control. It is a functional element in 5g networks that highlights the establishment, maintenance, and continuity of user sessions across different access technologies and network nodes.
    • Key Functions:
      • Session Control: SCC is Responsible for Controlling the Setup and Teardown of User Sessions, ENSURING THAT SESSIONS ARE ESTABLISED CORRECTLY AND MAINTENANCE continuity During Handovers or Transitions Between Different Access Technologies (EG, 5G to Wi-Fi).
      • Mobility Support: SCC Supports Seamless Mobility by Managing Handovers and transitions Between Cells or Network Nodes While Maintaining Session Continuity for Ongoing User Communications.
    • Integration With Core Network Elements:
      • SCC Interfaces with Core Network Elements to Coordinate Session Setup, Continuity, and Mobility Management. It ensures that user sessions remain uninterrupted even when moving across different areas of the network.
    • Example scenario:
      • In A 5G Network, SCC COULD BE INVOLVED IN MANAGING A USER's Session As Thray Move From One Cell to Another, ENSURING A SMOOTH HANDOVER AND continuity of the communication session without interruption.
  3. Differences:
    • Functional Focus:
      • PCC: Focuses on Policy Enfacing and Charging Control, Determining How Network Resources Are Allocated and How User Sessions Are Browed On Defined Policies.
      • SCC: Focuses on the Control of User Sessions, ENSURING THAT SESSIONS ARE ESTABLISED, STAINTAINED, AND TRANSITIONED SEAMLESSLY ACross Different Access Technologies and Network NODES.
    • Scope:
      • PCC: Primary in Managing Policies related to the Quality of Service, Prioritization of Traffic, and Charging Rules Associated With User Sessions.
      • SCC: Primary in the Establishment, continuity, and Mobility Support of User Sessions, Especially when Transitioning Between Different Areas of the Network.
    • Integration points:
      • PCC: Integrats with Various Network Elements to Enforce Policies and Charging Rules, Often Interfacing with the Policy Control Function and Charging Systems.
      • SCC: Integrats with Core Network Elements to Manage Session Setup, Continuity, and Mobility, Interacting with Responsible for Handovers and Transitions.
    • Example use boxes:
      • PCC: Customizes User Experiences by En Enlourcing Policies, Such as Prioritizing Criticals Applications OR PROVIDING DIFFERENTIATED SERVICES BASED ON USER Subscription Plans.
      • SCC: ENSURES SEAMLESS USER EXPERIENCES by Managing the continuity of sessions During Handovers and Transitions, Supporting Mobility Across Different Areas of the Network.

In Summary, While PCC Focuses On Policy Enforcement and Charging Control for User Sessions, SCC is primary concerned with the Establishment, Continuity, and Mobility Support of User Sessions Across Different Access Technologies and Network Nodes in 5G Networks. Both Elements Play Crucial Roles in Delivering A Reliable and Customizable User Experience in the Evolving Landscape of Mobile Communications.
