Network Provisioning for Direct P2P Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, such as LTE, do not efficiently provision mobile entities for peer-to-peer (P2P) services like device-to-device communication, as they typically require indirect communication through network infrastructure, lacking direct connections between mobile entities.
Innovation Solution
The proposed solution involves determining and sending P2P communication parameters to mobile entities for configuration, enabling direct device-to-device communication by authorizing and provisioning Service Discovery Identifiers (SD IDs) and prefixes, allowing mobile entities to detect and advertise P2P services within their proximity without relying on access nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If mobile entities communicate indirectly through network infrastructure, then network control and management are maintained, but direct peer-to-peer communication efficiency and speed are reduced
Solution Approach 1:
The communication system is segmented into two modes: indirect communication through network infrastructure and direct peer-to-peer communication. The patent enables mobile entities to switch between these modes by provisioning P2P parameters, allowing direct communication when appropriate while maintaining network-controlled indirect communication for other scenarios.
Solution Approach 2:
The communication architecture is made dynamic by allowing mobile entities to transition between indirect network-routed communication and direct P2P communication. The network provisions P2P parameters dynamically based on service requirements, enabling flexible adaptation between communication modes to optimize speed while managing complexity.
2Productivity
If direct peer-to-peer connections are established between mobile entities, then communication efficiency is improved, but network security control and authorization become more difficult
Solution Approach 1:
The network performs preliminary authorization and provisioning of P2P parameters before mobile entities establish direct connections. The network entity configures security parameters, authorizes P2P communication, and provisions necessary identifiers and keys in advance, ensuring security control is established before direct communication begins.
Solution Approach 2:
The system implements feedback mechanisms where mobile entities report P2P communication status and parameters to the network, and the network provides authorization decisions and parameter updates. This closed-loop control maintains security oversight while enabling efficient direct communication.
3Adaptability or versatility
If P2P communication parameters are provisioned to mobile entities, then direct communication capability is enabled, but network configuration complexity increases
Solution Approach 1:
The network entity is designed to perform multiple functions: it manages both traditional indirect communication and P2P communication provisioning, handles security authorization, and configures parameters for diverse P2P services. This multi-functionality reduces the need for separate specialized systems, managing complexity through consolidation.
Solution Approach 2:
The system manages P2P communication by provisioning and modifying parameters such as service discovery identifiers, communication keys, and authorization flags. The network entity controls P2P capability through parameter changes rather than structural modifications, enabling adaptability while managing complexity through parameterization.
4Reliability
If service discovery identifiers are authorized and provisioned, then communication privacy is enhanced, but provisioning and management overhead increases
Solution Approach 1:
Service discovery identifiers and authorization parameters are provisioned in advance by the network entity before P2P communication is needed. Mobile entities receive pre-configured identifiers and keys that enable immediate private communication without delays during the provisioning phase.
Solution Approach 2:
Mobile entities use the pre-provisioned service discovery identifiers to autonomously discover and establish P2P connections without requiring real-time network intervention. The identifiers enable self-service discovery and connection establishment, reducing provisioning time while maintaining privacy through authorized identifier usage.

AI summary
Techniques are provided for peer-to-peer (P2P) service provisioning. For example, there is provided a method, operable by a network entity, that may involve determining a set of region-specific parameters for use in the P2P service in a coverage area. The method may involve providing the set of the region-specific parameters to at least one user equipment (UE) for configuration of the at least one UE for the P2P service, in response to the at least one UE entering the coverage area. In related aspects, the set of the region-specific parameters may include RF parameters, service discovery parameters, connection establishment parameters, and/or security parameters
