Mobile Terminal Reusing Stored Access Addresses for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communications terminals require a new communications link setup for each access to a wireless local network, involving a new access address issuance, which is inefficient, especially when switching between networks.
Innovation Solution
A mobile communications terminal with a logon memory and an allocation memory that stores prior access addresses for different wireless local networks, allowing it to search and reuse earlier access addresses for simplified link setup and seamless network switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a new access address is issued by the DHCP server for each access request, then the mobile communications terminal can obtain a valid access address for the wireless local network, but the setup time and complexity of communications links increases
Solution Approach 1:
The mobile communications terminal performs preliminary actions by storing access addresses in a memory device before they are needed. When the terminal previously accessed a wireless local network, it saved the allocated access address in the memory device. Upon re-accessing the same network, the terminal retrieves and reuses this pre-stored address, eliminating the need for time-consuming new address allocation and link setup procedures.
2Device complexity
If a new access address is issued by the DHCP server for each access request, then the access address management is simplified on the server side, but the overall system complexity increases due to repeated link setup procedures
Solution Approach 1:
The mobile communications terminal provides self-service by autonomously managing its own access addresses through the memory device. The terminal independently retrieves and reuses its own previously allocated addresses without requiring server intervention for address reassignment. This shifts the complexity from server-side repeated allocation to client-side autonomous address management, simplifying the overall link setup procedure.
3Device complexity
If the mobile communications terminal stores only the last access address in a separate memory, then the memory structure is simple, but the terminal cannot efficiently access addresses for multiple different wireless local networks
Solution Approach 1:
The memory device is segmented into multiple storage entries, each associated with a specific wireless local network identifier. Instead of a single unified storage space, the memory is divided into network-specific segments that allow the terminal to efficiently retrieve addresses for different networks. This segmentation enables the terminal to store and access multiple access addresses corresponding to different wireless local networks while maintaining organized and efficient retrieval.

AI summary
The invention relates to a mobile communications terminal for use in a plurality of wireless local networks. Said terminal comprises a log on memory, in which an access address that is designed to be used for a new log on process is stored. According to the invention, information concerning the access addresses that were received by the mobile communications terminal in previous log on operations and the network among the plurality of wireless local networks that was used, is stored in an allocation memory. The terminal is configured in such a way that when a new access request is received for a sought network among the plurality of wireless local networks, it searches for a previous access address that was allocated for the sought network and is also configured in such a way that when said previous access address for the sought network has been found, it writes the address to the log on memory and permits the log on operation. The invention also relates to a method for managing log on information that is designed for the mobile communications terminal.
