Wireless Communication System TAI List Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, the simultaneous movement of multiple users across location registration area boundaries leads to a concentration of location registration processes on specific base stations, resulting in excessive consumption of wireless resources and increased power consumption for mobile terminals.
Innovation Solution
Allocating different Tracking Area Identity (TAI) lists to different mobile terminals based on their travel patterns, allowing the system to minimize the frequency of location registration processes and reduce the load on specific base stations by avoiding simultaneous boundary crossings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the same TAI list is allocated to multiple mobile terminals moving in the same area, then the location registration process is simplified and wireless resource consumption is reduced, but when multiple terminals simultaneously cross area boundaries, the load on specific base stations becomes excessive and power consumption increases
Solution Approach 1:
The patent segments the unified TAI list into multiple individual TAI lists, allocating different combinations of tracking area identities to different mobile terminals. This segmentation prevents simultaneous boundary crossings by multiple terminals, as each terminal has a customized TAI list tailored to its specific movement patterns. The segmentation resolves the contradiction by maintaining low wireless resource consumption while avoiding base station overload through differentiated area management.
Solution Approach 2:
The patent applies local quality by customizing TAI lists according to the specific movement characteristics and service requirements of each mobile terminal. Instead of using a uniform TAI list for all terminals, the system assigns locally optimized TAI lists that match individual terminal behaviors. This allows the system to maintain efficiency for each terminal while preventing concentrated load on specific base stations, thereby resolving the contradiction between resource efficiency and load balance.
2Measurement precision
If location registration is executed each time the mobile terminal moves between base stations, then the location accuracy is maintained and call notification is precise, but the location registration process is executed frequently, increasing wireless resource consumption and power consumption
Solution Approach 1:
The patent applies preliminary action by pre-calculating and allocating optimized TAI lists to mobile terminals based on their historical movement patterns and service requirements before actual movement occurs. This allows the system to anticipate future location changes and prepare appropriate tracking area configurations, reducing the need for frequent location registration executions while maintaining adequate location accuracy for call notification.
Solution Approach 2:
The patent implements dynamics by making the TAI lists adaptable and updatable based on changing movement patterns and service requirements. Rather than using static, fixed TAI lists, the system can dynamically adjust the TAI list contents to match actual terminal behavior, thereby optimizing the balance between location accuracy and registration frequency over time.
3Productivity
If a large TAI list is allocated to cover extensive movement areas, then the mobile terminal can move freely without frequent location registration, but the area coverage becomes too broad, reducing the precision of location-based call notification
Solution Approach 1:
The patent segments the tracking area coverage into customized TAI lists for different terminals based on their specific movement patterns. Instead of using a single large TAI list that covers all possible areas, the system creates segmented, terminal-specific lists that cover only the areas relevant to each terminal's behavior. This maintains movement freedom within the allocated areas while improving location precision by limiting the coverage scope to necessary regions only.

AI summary
A wireless communication system including a wireless terminal, a plurality of base stations and a call processing control unit is disclosed. The wireless terminal, upon reception of the notification information from any of the base stations, judges whether the area included in the notification information is contained in the location registration area list stored in a storage unit, and in the case where the particular area is not so contained, sends a location registration request to the call processing control unit. On the other hand, the call processing control unit creates a new location registration area list based on the area included in the notification information and the neighboring areas, and sends the location registration area list to the wireless terminal.
