Mobile Station P2P Transmission via Server IP Address Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile communication systems face challenges in establishing peer-to-peer (P2P) transmission due to the finite number of IP addresses, which are dynamically allocated and recycled, preventing stable connections between mobile stations.
Innovation Solution
A method and system that involves a server device to manage and update IP addresses and device information for mobile stations, allowing them to request and share IP addresses for establishing P2P transmissions by transmitting messages and updating receiving statuses, enabling successful data connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If dynamic IP address allocation is used to reduce wastage of network resources, then IP address efficiency is improved, but the ability to establish stable P2P transmission is worsened
Solution Approach 1:
The system segments IP address management into two distinct pools: a dynamic pool for general network resource allocation and a reserved pool specifically for P2P transmissions. This segmentation allows the system to maintain high overall IP address utilization efficiency while ensuring stable P2P connections by dedicating specific addresses for this purpose.
Solution Approach 2:
The system performs preliminary allocation of IP addresses from the reserved pool before P2P transmission begins. By pre-allocating addresses and establishing their binding relationships in advance, the system ensures that when P2P transmission is needed, stable addresses are already available, eliminating the instability caused by dynamic reallocation during active transmission.
2Loss of energy
If IP addresses are recycled when mobile station is turned off or service is terminated, then network resource efficiency is improved, but P2P connection establishment becomes difficult
Solution Approach 1:
The system implements dynamic management of IP address pools with different recycling policies. The dynamic pool allows aggressive recycling to maximize resource efficiency, while the reserved pool maintains stability for P2P operations. The system dynamically selects from which pool to allocate addresses based on the transmission type, achieving both resource efficiency and connection ease.
Solution Approach 2:
The system introduces an intermediary mechanism - the reserved IP address pool - that mediates between the need for resource recycling and the need for stable P2P connections. This intermediary pool acts as a buffer, allowing general addresses to be recycled aggressively while P2P addresses remain stable, thus resolving the contradiction between resource efficiency and connection establishment ease.
3Adaptability or versatility
If mobile stations do not have fixed IP addresses, then network resource flexibility is improved, but the ability to maintain continuous P2P transmission is worsened
Solution Approach 1:
The system segments IP address management into dynamic and reserved pools, allowing flexible allocation from the dynamic pool for general purposes while maintaining fixed assignments from the reserved pool for P2P transmissions. This segmentation enables the system to simultaneously achieve network resource flexibility and P2P transmission continuity.
Solution Approach 2:
The system changes the parameter of IP address fixedness based on the type of transmission. For general network traffic, IP addresses remain dynamic to maintain flexibility. For P2P transmissions, the system changes the parameter to fixed by allocating from the reserved pool, thereby ensuring transmission continuity while preserving overall network flexibility.

AI summary
A method for establishing peer-to-peer (P2P) transmission in a mobile communication system includes a first mobile station requesting the mobile communication system for a first Internet Protocol (IP) address and transmitting a message to a second mobile station to indicate the second mobile station to trigger the P2P transmission when the first mobile station starts to establish the P2P transmission with the second mobile station, the second mobile station requesting the mobile communication system for a second IP address according to the message, the first and second mobile stations updating receiving statuses of the first and second IP addresses to a server device, and the server device outputting information of the second IP address to the first mobile station after the first and second mobile stations obtain the first and second IP addresses, to allow the first mobile station to establish the P2P transmission with the second mobile station accordingly.
