Solution Overview
Problem
The complexity of network engineering in wireless communication systems is exacerbated by the mobile nature of users, leading to difficulties in predicting bandwidth requirements and optimizing resource allocation across diverse access technologies, resulting in inadequate network resources and service issues.
Innovation Solution
The use of location-based information (LBI) is integrated into network registration processes to determine optimal access technologies and routing decisions, allowing the network to dynamically adjust resource allocation and handoff between different access technologies based on real-time device and infrastructure location data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple access technologies are supported to meet diverse user requirements, then network versatility and user access capability are improved, but network engineering complexity increases
Solution Approach 1:
The patent changes the parameter of access technology selection from device-autonomous to network-controlled. The network controller receives location-based information from mobile devices and autonomously determines the optimal access technology (cellular, WiFi, WiMAX) based on real-time location data, transforming the decision-making parameter from device-level to network-level control
Solution Approach 2:
The patent implements a feedback mechanism where mobile devices continuously provide location-based information to the network controller, which then adjusts access technology assignments in real-time based on the device's current location and network conditions, creating a closed-loop control system
2Measurement precision
If access control engineering is performed without location-based information, then network configuration is simpler, but bandwidth requirement prediction and resource allocation become inaccurate
Solution Approach 1:
The patent applies preliminary action by collecting location-based information from mobile devices during the registration process before actual bandwidth requirements arise. This advance data collection enables the network to predict future bandwidth needs and pre-allocate resources, transforming reactive resource management into proactive planning
Solution Approach 2:
The patent adds the dimension of location-based information to traditional access control engineering. By incorporating geographic location data into the resource allocation decision-making process, the system transitions from two-dimensional (device ID and bandwidth requirement) to three-dimensional (device ID, location, and bandwidth requirement) resource management
3Productivity
If location-based information is collected and used for access decisions, then network resource allocation efficiency is improved, but data processing and registration process complexity increase
Solution Approach 1:
The patent merges the location-based information collection with the existing device registration process. Instead of adding a separate data collection step, the system integrates LBI extraction and processing into the standard registration procedure, combining multiple functions into a single unified process
Data Source
AI summary
A method and apparatus is disclosed whereby location based information (LBI) is used to make access and routing decisions within a network. Such LBI is sent from mobile devices to the core network when the mobile device registers with the network and is updated periodically. Over time, this collected LBI data represents the position of mobile devices over time and periodic patterns of usage in different geographic areas. When a network receives an indication that a mobile device requires registration with the network, the network determines as a function of said LBI, a desired network access technology to use to connect said mobile device with the network. Instructions are then transmitted to the mobile device to establish a connection using said desired network access technology and the device is registered with the network. Dynamically updated LBI information from mobile devices is also used for IP network routing optimization.
