PSP-ID Type Indication in MulteFire System Messages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for indicating Participating Service Provider Identities (PSP-IDs) in MulteFire networks are inefficient due to high overheads, as each PSP-ID needs to carry type indication information, limiting the number of PSP-IDs that can be broadcasted in System Information Blocks.
Innovation Solution
A method where PSP-IDs of the same type are sequentially arranged and ordered, with indication information used to identify their location, reducing the need for type indication within each PSP-ID and minimizing overheads by using a preset sequential order and location indication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If each PSP-ID carries type indication information, then the type of each PSP-ID can be clearly identified, but the overhead for indicating PSP-ID types becomes excessively large
Solution Approach 1:
The patent merges the type indication information with the PSP-ID itself by embedding the type as the most significant bits within the PSP-ID structure. This consolidation eliminates separate type indication fields, reducing overhead while maintaining clear type identification capability.
Solution Approach 2:
The PSP-ID structure is designed to serve multiple functions simultaneously: it identifies the service provider, indicates the type of service provider through its bit structure, and provides a unique identifier. This multi-functionality eliminates the need for separate type indication mechanisms.
2Loss of information
If each PSP-ID carries type indication information, then the type of each PSP-ID can be clearly identified, but the number of PSP-IDs that can be broadcasted in System Information Blocks is limited
Solution Approach 1:
By merging type indication into the PSP-ID structure itself, the patent reduces the total bit requirement for each PSP-ID entry. This efficiency allows more PSP-IDs to be accommodated within the fixed capacity of System Information Blocks, increasing the number of service providers that can be broadcasted.
3Adaptability or versatility
If PSP-IDs are arranged without a preset sequential order, then flexibility in assignment is maintained, but overhead for indicating location and type increases
Solution Approach 1:
The patent establishes a preset sequential order for different types of PSP-IDs in advance. This preliminary arrangement allows receiving devices to predict and efficiently locate specific types of PSP-IDs without requiring additional indication overhead, while still maintaining flexibility in the actual assignment of PSP-ID values within each type category.

AI summary
The present disclosure provides a method and apparatus for indicating the type of a participating service provider identity (PSP-ID). The method comprises: an access device generates a system message, the system message comprising multiple PSP-IDs, PSP-IDs of the same type among the multiple PSP-IDs being sequentially arranged, and PSP-IDs of different types being arranged according to a preset order, the system message also comprising indication information of the PSP-IDs of each type, and the indication information being used for indicating the locations of the PSP-IDs of each type; and the access device sends the system message.
