UE Session Join Notification Sharing for SEAL Network Resource Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 3GPP technical specifications do not provide a procedure for the SEAL network resource management client (SNRM-C) to share UE session join notifications when a vertical application layer (VAL) user joins a multicast or broadcast service session over a 5G network, which is crucial for informing the VAL group server about user readiness to send or receive group media.
Innovation Solution
A method and system are implemented to enable the SNRM-C to share UE session join notifications using the HTTP protocol, specifically through generating and transmitting an HTTP POST request containing MBS session join information in XML format to the SNRM-S, allowing seamless communication and resource management for group services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the SNRM-C shares UE session join notifications using HTTP protocol, then the VAL server can determine user readiness and manage network resources effectively, but the device complexity and implementation overhead increase due to additional protocol integration
Solution Approach 1:
The HTTP protocol is leveraged as a universal communication mechanism that can carry multiple types of network management information including UE session join notifications, resource status updates, and control commands. This multi-functional use of HTTP simplifies the overall architecture by replacing multiple specialized protocols with a single versatile protocol stack.
Solution Approach 2:
The patent introduces an HTTP-based intermediary layer between the SNRM-C and VAL server that translates internal network management events into standardized HTTP requests and responses. This mediator pattern isolates the complexity of protocol translation while maintaining clean interfaces between network management functions and application layer services.
2Loss of information
If detailed UE session join notification information is transmitted, then the VAL server gains complete visibility for resource management, but the information transmission overhead and processing load increase
Solution Approach 1:
The patent extracts and transmits only the essential elements of UE session join notifications through HTTP messages, specifically focusing on critical identifiers (UE ID, session ID, service type) and status indicators. Non-essential detailed information is either omitted or transmitted separately on-demand, reducing the core notification payload to minimal necessary data.
Solution Approach 2:
The notification mechanism dynamically adjusts the level of detail transmitted based on session context, UE capabilities, and server requirements. Critical parameters are always included while optional parameters are conditionally transmitted, allowing the information completeness to be optimized for each specific scenario rather than using a fixed detailed format.
Data Source
AI summary
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Disclosed is a method and system for sharing a user equipment (UE) session join notification for a multicast and broadcast services (MBS) session in 5th generation (5G) using service enabler architecture layer (SEAL) network resource management (SNRM) service. The method includes generating, by the UE, a hypertext transfer protocol (HTTP) POST request based on a request from a vertical application layer (VAL) client of the UE, and transmitting, by the UE, the UE session join notification for the MBS session using the HTTP POST request to a SEAL network resource management-server (SNRM-S).
