Multicast Session Joining via Rejection Threshold Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3GPP 5G specifications for joining a multicast session in communication networks are limiting and inefficient, leading to rejected control plane join requests due to unavailability of multicast distribution sessions.
Innovation Solution
An apparatus and method that processes control plane join requests, determines the number of rejected requests, and decides to establish a multicast distribution session based on the number of rejections, allowing subsequent join requests and providing information to other network entities, thereby optimizing multicast session management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the network strictly follows current 3GPP specifications for multicast session joining, then the network operation is simple and compliant, but the efficiency of joining multicast sessions is limited and many join requests are rejected
Solution Approach 1:
The network entity dynamically adjusts its behavior based on real-time conditions. When a multicast distribution session is not available, the network entity counts rejected CP join requests and establishes a multicast distribution session when a threshold number of rejections is reached. This dynamic adaptation allows the system to optimize multicast session joining efficiency while managing complexity through condition-based decision making.
Solution Approach 2:
The network entity implements feedback mechanisms by monitoring the number of rejected CP join requests for each multicast address. Based on this feedback, the network entity determines when to establish new multicast distribution sessions. This feedback loop enables the system to learn from rejection patterns and proactively create sessions to accommodate future join requests, thereby improving overall joining efficiency.
2Reliability
If the network establishes multicast distribution sessions frequently, then user equipment access to multicast services is improved, but network resources are consumed more heavily
Solution Approach 1:
The network entity autonomously manages multicast distribution session establishment based on observed join request patterns. When the number of rejected CP join requests reaches a predetermined threshold, the network entity automatically establishes a multicast distribution session without requiring external intervention. This self-service capability ensures reliable user equipment access while avoiding unnecessary resource consumption by only creating sessions when actually needed.
Solution Approach 2:
The network entity changes its operational parameters dynamically - specifically, the threshold value for establishing multicast distribution sessions. By adjusting this parameter and other control settings based on network conditions and rejection patterns, the system optimizes the balance between ensuring reliable service access and conserving network resources. This parameter adaptation allows flexible resource management tailored to actual demand.

AI summary
Methods, systems, apparatuses, and computer program products are provided for joining a multicast session of a communications network. In this regard, a control plane (CP) join request for a multicast service is received from user equipment. Furthermore, provision of a reject message associated with the CP join request to the user equipment is caused in response to a determination that a multicast distribution session is not available for a multicast address associated with the CP join request.
