Mobile Network P2P Stream Authorization Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile telecommunications networks, the prohibition of peer-to-peer (P2P) data flows increases latency and operational costs for service providers and network operators, while restricting user experience, due to the need for media relays which extend data transmission paths and require additional infrastructure.
Innovation Solution
A method that allows network operators to authorize or refuse P2P streams based on service provider agreements, media type, and available bandwidth, enabling direct P2P communication within the mobile network while maintaining control, and optionally routing refused streams through media relay servers for increased security and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If P2P data flows are prohibited on mobile networks, then network control and security are improved, but latency increases and user experience deteriorates
Solution Approach 1:
The patent applies local quality by differentiating the treatment of P2P flows based on their characteristics. Authorized P2P flows (e.g., from trusted service providers) are allowed to pass through directly with low latency, while unauthorized or suspicious flows are blocked or routed through media relays. This selective approach maintains network control for critical flows while preserving low latency for trusted communications.
Solution Approach 2:
The patent introduces a media relay server as an intermediary for flows that require additional control or security inspection. Instead of uniformly blocking all P2P flows, the system uses the media relay as a mediator that can inspect, authenticate, and route flows appropriately. This resolves the contradiction by providing network control through the intermediary while allowing direct P2P paths for authorized flows.
2Reliability
If P2P streams are forced through media relay servers, then network control and security inspection are improved, but operational costs and infrastructure requirements increase
Solution Approach 1:
The system applies local quality by providing security inspection and media relay services only where necessary. Trusted P2P flows from authorized service providers bypass the media relay infrastructure, while only flows requiring additional security verification are routed through the media relay servers. This reduces overall infrastructure requirements while maintaining security inspection capabilities.
Solution Approach 2:
The patent extracts the security inspection function from a universal P2P blocking approach and applies it selectively. Instead of forcing all P2P flows through media relays, the system extracts and applies security inspection only to flows that require it, thereby reducing infrastructure complexity and operational costs while maintaining necessary security controls.
3Reliability
If all P2P flows are blocked, then network policy enforcement is improved, but service provider costs and user experience deteriorate
Solution Approach 1:
The patent applies local quality by differentiating between authorized and unauthorized P2P flows. Service provider flows from trusted sources are allowed to pass through with minimal intervention, maintaining high service availability and low costs. Only flows that violate network policy or come from untrusted sources are blocked or routed through media relays, thus preserving productivity while enforcing policy.
Solution Approach 2:
The system converts the potential harm of uncontrolled P2P flows into a benefit by using the media relay infrastructure for authorized flows that require quality of service guarantees or priority treatment. This allows the system to maintain policy enforcement while actually improving service availability for critical P2P communications by giving them dedicated routing paths.

AI summary
The invention relates to a method for authorising the establishment of a peer-to-peer stream between two user terminals of a mobile telecommunications network, the method being implemented in a platform of the mobile telecommunications network and including the following steps: receiving, from a server of a peer-to-peer service provider, a request to establish a peer-to-peer stream between a first user terminal and a second user terminal, the establishment request including a stream identifier, the stream identifier including at least one identifier of the first user terminal and an identifier of the second user terminal; deciding whether or not to authorise the establishment of the peer-to-peer stream between the first user terminal and the second user terminal; and transmitting a message to authorise or reject the peer-to-peer stream to a network gateway in charge of controlling the streams that pass through the mobile telecommunications network, the authorisation or rejection message including the stream identifier.
