Broadcast Service Identifier Segmentation for MBS Resource Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face challenges in efficiently managing broadcast services across multiple base stations, leading to increased resource consumption and time delays due to limitations in the number of broadcast service identifiers and the need for repeated connection setups when moving between MBS zones.
Innovation Solution
The introduction of a method that allows for the allocation of a first identifier for a broadcast service and additional identifiers for individual content broadcasts, using a Multiple Broadcast Service ID TLV Encoding and Logical Channel IDs to extend the number of available identifiers, enabling a single connection setup for multiple services and minimizing resource consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional broadcast service identifier allocation is used, then the system is simple to operate, but the number of available identifiers is limited
Solution Approach 1:
The broadcast service identifier is segmented into two distinct parts: a first identifier for the broadcast service and a second identifier for the content broadcast. This segmentation allows the system to support a larger number of identifiers by combining two smaller identifier spaces, resolving the limitation on the total number of available identifiers while maintaining manageable complexity through clear functional separation.
Solution Approach 2:
The identifier system transitions from a single-dimensional identifier space to a two-dimensional identifier space by introducing both a first identifier (for broadcast service) and a second identifier (for content broadcast). This dimensional expansion significantly increases the total number of unique identifier combinations available, solving the identifier exhaustion problem.
2Loss of time
If connection setup is performed for each broadcast service separately, then the system maintains simplicity in service management, but time delays increase when moving between MBS zones
Solution Approach 1:
Multiple connection setup procedures are merged into a single unified connection setup process. The mobile station performs one connection setup that establishes reception for both the first broadcast service and the second content broadcast simultaneously, eliminating the need for separate connection setups and reducing time delays when moving between MBS zones.
Solution Approach 2:
The connection setup procedure is enhanced to serve multiple functions: it simultaneously establishes reception for the broadcast service and the content broadcast. This multi-functional approach allows a single connection setup to manage multiple identifier allocations, reducing the overall setup time and procedural complexity.
3Loss of energy
If multiple connection setups are performed for multiple services, then service identification is straightforward, but resource consumption increases
Solution Approach 1:
The allocation of first identifier and second identifier is merged into a single resource allocation event. When the mobile station performs one connection setup, the base station allocates both identifiers simultaneously, reducing the overall resource consumption compared to performing separate allocation events for each identifier.
Solution Approach 2:
The system performs preliminary allocation of both identifiers during the initial connection setup, before the mobile station needs to use them. This preliminary action ensures that both identifiers are ready for immediate use, eliminating the need for additional resource-consuming allocation operations later.

AI summary
Disclosed is a broadcast service connection setup method for receiving a Multicast and Broadcast Service (MBS) by a mobile station (MS) in a mobile communication system supporting the MBS. The MS sends a connection setup request for a particular broadcast service to a base station (BS). The MS receives from the BS a first identifier mapped to the particular broadcast service and second identifiers individually mapped to at least one content broadcast.
