IP Management Connection Control in Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-speed portable Internet systems, the static IP address allocation method limits mobility, while the dynamic IP address allocation method requires additional connections for IP management messages, leading to resource wastage in access point resources.
Innovation Solution
Establishing a first traffic connection to a packet access router and uplink and downlink traffic connections to an access terminal for transmitting IP management messages, eliminating the need for an auxiliary management connection and optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dynamic IP address allocation method is used to support mobility, then access terminal can move between cells with IP address reestablishment, but additional auxiliary management connection is required leading to access point resource wastage
Solution Approach 1:
The patent merges the IP management message transmission function with the existing traffic connection by allowing IP management messages to be carried as data packets over the uplink and downlink traffic connections. This eliminates the need for a separate auxiliary management connection, thereby reducing access point resource consumption while maintaining mobility support capabilities.
Solution Approach 2:
The traffic connection is given multi-functionality by enabling it to carry both traffic data and IP management messages. The uplink traffic connection and downlink traffic connection serve dual purposes: transmitting user data and conveying IP management information, thus eliminating the need for dedicated management connection resources.
2Quantity of substance
If static IP address allocation method is used, then access point resources are saved by not requiring IP managing messages, but access terminal cannot move between cells losing mobility
Solution Approach 1:
The patent combines IP management message transmission with traffic connection usage, allowing the same connection infrastructure to serve both static and dynamic allocation scenarios. This enables mobility support through dynamic allocation while utilizing existing traffic connection resources rather than requiring additional management connection resources.
3Adaptability or versatility
If auxiliary management connection is established for IP address allocation, then dynamic IP address allocation and mobility are supported, but transport connection ID and service flow resources are wasted
Solution Approach 1:
The patent merges the functions of traffic data transmission and IP management message transmission into a single traffic connection. By carrying IP management messages as data packets over the uplink and downlink traffic connections, the system eliminates the need for separate auxiliary management connections, thereby preventing wastage of transport connection ID and service flow resources while maintaining IP address allocation flexibility.

AI summary
The present invention relates to an Internet protocol (IP) management connection control method in a mobile communication system. In the method, a first traffic connection between an access point and a packet access router is established, uplink and downlink second traffic connections between the access point and an access terminal are established, and an IP management message is transmitted through the first traffic connection and the second traffic connection.
