Terminal IP Address Allocation for Wireless Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face challenges in efficiently allocating Internet Protocol (IP) addresses to terminals for data transmission, particularly in managing context information to facilitate efficient data transmission across multiple linked terminals with varying bit rates and Quality of Service (QoS) parameters.
Innovation Solution
A method and device for transceiving data that involves requesting context information from a Home Subscriber Server (HSS), allocating terminal IP addresses, and configuring sessions with gateways to manage IP addresses and bit rates across linked terminals, ensuring efficient data transmission and reception based on maximum bit rates and QoS parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If IP addresses are allocated to each terminal individually, then each terminal can communicate independently, but data transmission efficiency across multiple linked terminals is reduced
Solution Approach 1:
The patent merges multiple terminals into a single group sharing a common IP address. The network side treats the group as one entity for IP addressing, while internally managing individual terminal identities through group identifiers. This combining approach enables efficient data transmission across terminals without requiring separate IP addresses for each device, resolving the contradiction between transmission efficiency and address management complexity.
Solution Approach 2:
The patent implements a universal IP address that serves multiple terminals simultaneously. A single IP address functions as the communication endpoint for an entire terminal group, allowing the network to communicate with multiple devices using one address. This multi-functional IP address approach improves productivity by enabling efficient group communication while avoiding the complexity of managing individual addresses for each terminal.
2Productivity
If context information is stored for each terminal separately, then terminal identification is precise, but information management overhead increases
Solution Approach 1:
The patent combines context information management by storing shared context data at the group level rather than duplicating it for each terminal. The network side maintains a single context record for the terminal group, reducing information management overhead while still enabling precise terminal identification through individual terminal identifiers stored within the group context.
Solution Approach 2:
The patent creates a universal context information structure that serves multiple terminals within a group. This single context record contains information applicable to all group members, reducing the total volume of stored information while maintaining the ability to manage individual terminal communications through embedded terminal identifiers and group-level parameters.
3Speed
If the same IP address is allocated to multiple terminals, then data transmission rate increases, but address allocation complexity increases
Solution Approach 1:
The patent introduces a group identifier as an intermediary between the shared IP address and individual terminals. The network side uses the group identifier to route data to the appropriate terminal within the group, while the terminal side uses the shared IP address for communication. This intermediary mechanism enables high-speed transmission through IP address sharing while managing allocation complexity through systematic group identification.
Solution Approach 2:
The patent segments the addressing function into two parts: a shared IP address for group-level communication and a group identifier for terminal-level differentiation. This segmentation allows multiple terminals to share one IP address for efficient data transmission while the group identifier provides the necessary distinction for proper routing, managing the complexity of address allocation through functional division.
