WiMAX Multicast ID Assignment via Segmented MCID LCID Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current WiMAX multicast broadcast systems lack detailed methods for assigning and managing multicast connection IDs (MCIDs), multicast content IDs, and logical channel IDs (LCIDs), which are crucial for efficient data transmission and resource utilization in both single-BS and multi-BS modes, leading to inefficiencies in data distribution and resource management.
Innovation Solution
The method involves assigning transmission IDs that include MCIDs and LCIDs to identify air interface links and logical channels, allowing terminals to receive multicast broadcast services by using a preset correspondence between MBS content IDs and LCIDs, enabling efficient data transmission through logical channels identified by MCIDs and LCIDs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multicast broadcast service is implemented without detailed ID assignment methods, then service coverage is achieved, but data transmission efficiency and resource utilization deteriorate
Solution Approach 1:
The patent segments the identification system into three distinct ID types: MCID (Multicast Connection ID) for identifying multicast connections, MBS Content ID for identifying multicast content, and LCID (Logical Channel ID) for identifying logical channels. This segmentation allows each ID to serve a specific function, improving data transmission efficiency while managing complexity through clear functional separation.
Solution Approach 2:
The patent assigns different ID types to different layers and functions within the multicast broadcast service architecture. MCID operates at the connection layer, MBS Content ID at the content layer, and LCID at the channel layer. This local quality assignment ensures that each ID manages the appropriate level of detail, optimizing both transmission efficiency and management complexity.
2Measurement precision
If multiple ID types are assigned for detailed identification, then resource management precision is improved, but system complexity increases
Solution Approach 1:
The patent divides the identification system into three segmented ID types (MCID, MBS Content ID, LCID) that operate at different levels of the protocol stack. This segmentation enables precise resource management at each level while preventing the accumulation of complexity in a single identification mechanism.
Solution Approach 2:
The patent introduces identification precision along a new dimension by adding multiple ID types that operate independently at different protocol layers. Instead of increasing complexity within a single ID system, the solution adds dimensional depth to identification, allowing precise resource management without linearly increasing overall system complexity.
3Adaptability or versatility
If single-BS mode is used for multicast transmission, then system complexity is reduced, but adaptability to different network configurations deteriorates
Solution Approach 1:
The patent creates a universal ID assignment mechanism that functions across both single-BS and multi-BS network configurations. The same three ID types (MCID, MBS Content ID, LCID) and their correspondence relationships work regardless of the number of base stations, providing network configuration adaptability without requiring separate complex configuration systems for each mode.
Solution Approach 2:
The patent implements a dynamic ID management system where the correspondence between MCID, MBS Content ID, and LCID can be flexibly configured based on network conditions. This dynamic approach allows the system to adapt to different network configurations (single-BS or multi-BS) while maintaining a consistent underlying framework, balancing adaptability with manageable complexity.

AI summary
A method, a system, and a terminal for sending and receiving a multicast broadcast service (MBS) are provided in the communication field. Based on a preset correspondence between MBS content IDs and LCIDs, a network side sends MBS data with an LCID corresponding to the MBS content ID in an air interface link identified by an MCID. A terminal generates a corresponding LCID from the MBS content ID of the MBS based on the same correspondence as that of the network side, and receives data via a logical channel identified by the LCID in the air interface link identified by the MCID of the required MBS. A method for assigning an MBS information ID is also provided. The uniqueness of the MBS content ID can be guaranteed within an operator, an access service network (ASN), or an MBS zone.
