Local Broadcast Channel Authentication Without BMSC Forwarding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for broadcasting or multicasting content in networks are inefficient, unreliable, and time-consuming due to the need to forward Local Broadcast data to the BMSC and back to the RAN, and require Authentication and Authorization by the BMSC, which can be cumbersome.
Innovation Solution
A system and method that enables broadcasting or multicasting within the RAN and core network, avoiding forwarding Local Broadcast data to the BMSC and reusing core network authentication during initial Attach or Registration procedures, allowing User Equipment to act as Content Providers or Sources, and establishing local broadcast channels for emergency situations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Local Broadcast data is forwarded to BMSC and back to RAN for authentication and authorization, then security and service management are ensured, but system time consumption increases and efficiency decreases
Solution Approach 1:
The patent performs authentication and authorization in advance during initial network attachment or registration procedures. The UE is authenticated by the core network before it needs to send Local Broadcast data, so when the actual broadcast occurs, the authentication is already complete, eliminating the need for repeated BMSC authentication and reducing time consumption.
Solution Approach 2:
The patent extracts the authentication function from the BMSC and performs it through the core network during initial attachment. This separates the authentication process from the data forwarding process, allowing authentication to occur independently in advance while data can be forwarded directly without waiting for BMSC authorization.
2Reliability
If BMSC authentication and authorization procedures are followed for content broadcasting, then service security is maintained, but system complexity and operational difficulty increase
Solution Approach 1:
The patent uses the core network's existing authentication infrastructure to serve multiple purposes - both initial network access authentication and subsequent Local Broadcast authentication. This multi-functional use of the authentication system eliminates the need for separate BMSC authentication procedures, reducing system complexity while maintaining security.
Solution Approach 2:
The UE performs self-authentication through the core network during initial attachment without requiring separate BMSC intervention. The authentication is automatically handled by the network infrastructure already in place, reducing operational complexity and making the process more self-service oriented.
3Extent of automation
If data is forwarded through BMSC for processing, then centralized control is maintained, but productivity and content distribution speed decrease
Solution Approach 1:
The patent segments the content distribution process into two independent parts: authentication (handled by core network in advance) and data forwarding (handled directly by RAN). This segmentation allows the data forwarding to occur without waiting for BMSC processing, significantly improving productivity while the core network maintains centralized control over authentication.
Solution Approach 2:
By performing authentication in advance before data forwarding, the patent eliminates the sequential dependency where data must wait for BMSC processing. The preliminary authentication allows subsequent data distribution to proceed independently and rapidly, improving productivity while maintaining centralized security control.

AI summary
Present disclosure generally relates to wireless communication, particularly to system and method for broadcasting or multicasting content in networks. The system receives establishment request to establish broadcast channel via UE communicatively coupled to device and authenticates device or UE for establishing broadcast channel. The system determines, if devices or UE is authorized to establish broadcast channel and transmits response corresponding to request, to device or UE. The system receives membership notification corresponding to membership setup request associated with membership, from device of UE and transmits membership confirmation response corresponding to membership setup request. The system triggers authentication of device of UE, service type identification, and paging of broadcast membership, multicast membership, for initiating broadcast by device or UE System broadcasts or multicasts content received from device or UE, upon triggered authentication is successful.
