Local Area Network Communication Association for Bandwidth and Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing instant messaging (IM) programs like QQ consume network bandwidth and reduce network speed when multiple users communicate simultaneously, and there are uncertainties in network security, leading to potential information leaks.
Innovation Solution
A method and apparatus for communication program association based on a local area network, which involves acquiring a communication program account number, sending a communication association request, and establishing communication association within the local area network, thereby utilizing local network transmission advantages to reduce bandwidth occupation and enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple QQ users communicate simultaneously using existing IM programs, then communication functionality is achieved, but network bandwidth is occupied and network speed is reduced
Solution Approach 1:
The patent segments communication into two paths: local area network communication for nearby users and wide area network communication for remote users. By dividing the communication network into local and remote segments, the patent enables local users to communicate without occupying wide area network bandwidth, thus resolving the contradiction between communication functionality and network bandwidth consumption
Solution Approach 2:
The patent introduces a location server as an intermediary that determines whether communicating users are nearby or remote. This intermediary enables the system to automatically select the appropriate communication path (local or wide area network), thereby preventing unnecessary occupation of network bandwidth while maintaining communication functionality
2Productivity
If multiple QQ users communicate simultaneously through the network, then communication is enabled, but network security uncertainties lead to information leaks
Solution Approach 1:
The patent segments communication channels into trusted local network paths and public wide area network paths. By identifying nearby users and establishing direct local network connections, the patent creates a more secure communication environment that is isolated from public network vulnerabilities, thus improving information security while maintaining communication capability
Solution Approach 2:
The patent applies different security qualities to different communication scenarios: local area network communication with enhanced security for nearby users, and standard wide area network communication for remote users. This local quality approach ensures that security measures are applied where most needed (local trusted network) without unnecessarily compromising communication convenience
3Adaptability or versatility
If geographic position matching is enabled to find nearby users, then user discovery capability is improved, but network resource consumption increases
Solution Approach 1:
The patent extracts the location query function from continuous network operations and implements it as an on-demand local area network broadcast. Instead of continuously consuming network resources to maintain geographic position matching, the system only activates location queries when users actively seek nearby contacts, thus reducing overall network resource consumption while preserving user discovery capability

AI summary
Embodiments of the present disclosure provide a method for communication program association. The method includes acquiring a communication program account number in the local area network; sending a communication association request to the communication program account number in the local area network; and receiving communication association confirmation information returned by the communication program account number in the local area network, and establishing communication association with the communication program account number in the local area network. Because the established associated communication program account number does not occupy significant network bandwidth in the communication process, the network transmission speed is improved. Because communication is performed on the local network, security of communication information is ensured.
