Radio Base Station Location Acquisition via Terminal Capability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing radio base station systems experience increased network traffic due to signaling between the base station and a location information server when acquiring radio terminal location information, which is inefficient and can lead to communication delays and processing overhead.
Innovation Solution
A radio base station that requests and determines the positioning capability of connected radio terminals and relay stations, allowing it to acquire location information directly from them if capable, thereby omitting the need for server-based acquisition and reducing network traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the radio base station acquires radio terminal location information from the location information server, then the location information can be obtained, but the network traffic increases due to signaling between the base station and server
Solution Approach 1:
The radio terminal determines its own location information using its positioning capability (e.g., GPS receiver) and directly provides it to the radio base station, eliminating the need for the base station to query the location information server. This self-service approach reduces signaling traffic while ensuring accurate location information is obtained.
2Difficulty of detecting and measuring
If the radio base station queries the location information server for terminal capability information, then the positioning capability can be determined, but the signaling overhead and network traffic increase
Solution Approach 1:
The radio terminal proactively transmits its terminal capability information (including positioning capability) to the radio base station in advance, before the base station needs to query the server. This preliminary action eliminates the need for capability detection signaling between the base station and server, reducing overhead while ensuring the base station has the necessary information for location acquisition.

AI summary
A radio base station (100) transmits a Capability Request message to a radio terminal (200), which is connected to the radio base station, to transmit terminal capability information that indicates positioning capability of the radio terminal, and receives a Capability Indication message transmitted from the radio terminal (200). The radio base station (100) determines, corresponding to the received Capability Indication message, whether positional information that indicates the geographical position of the radio terminal (200) can be acquired from the radio terminal (200).
