Base Station Identifier Allocation for Idle No-Mobility Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of methods for allocating and managing identifiers for idle-state mobile stations with no mobility in wireless communication systems, which hinders efficient identification and communication management.
Innovation Solution
A method is introduced where a base station receives mobility information from mobile stations and allocates a unique identifier to idle-state mobile stations with no mobility, allowing for efficient identification and communication optimization by transmitting this identifier back to the mobile stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a base station manages all mobile stations using traditional identification methods, then general communication functionality is maintained, but idle-state mobile stations with no mobility cannot be efficiently identified or managed
Solution Approach 1:
The patent segments mobile stations into different categories based on mobility characteristics. It introduces a specific identifier type (F-TEMSI) dedicated to fixed/mobile-station-with-no-mobility in idle state, separating them from mobile stations that require traditional mobility management. This segmentation enables efficient identification of the specific subset of MSs without complicating the overall system for other MS types.
2Adaptability or versatility
If traditional identifier allocation methods are used for all mobile stations, then universal compatibility is maintained, but specific needs of idle-state mobile stations with no mobility are not met
Solution Approach 1:
The patent applies local quality by making the identifier allocation method dependent on the specific characteristics of the mobile station. When a mobile station has no mobility and is in idle state, the base station allocates a specific F-TEMSI identifier. This localized adaptation ensures that identifier allocation is tailored to the specific needs of each MS type, preserving mobility information through appropriate identifier selection.
3Loss of energy
If mobile stations frequently enter and exit idle state, then power saving and resource optimization are achieved, but identification and management overhead increases
Solution Approach 1:
The patent implements preliminary action by allocating the F-TEMSI identifier to mobile stations when they transition to idle state with no mobility. This pre-allocation ensures that when these MSs need to be identified or woken up, the base station already has the appropriate identifier ready, eliminating the need for time-consuming identifier allocation procedures during each idle state transition.

AI summary
Disclosed are a method and a device for transmitting/receiving an identifier for a no-mobility mobile station in an idle state in a wireless communication system. In a base station device for transmitting an identifier for a no-mobility mobile station in an idle state, according to the present invention, a receiver receives information on mobility from at least one mobile station. A processor allocates, to the at least one no-mobility mobile station in an idle state, at least one identifier for a no-mobility mobile station in an idle state for a no-mobility mobile station in an idle state on the basis of the information on mobility. A transmitter transmits the allocated identifier to the at least one no-mobility mobile station in an idle state.
