Position Information Distribution Server Reducing HLR Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing position information transmission systems increase the load on communication carrier facilities, such as HLR, when multiple systems operate, leading to potential disruptions during communication line congestion, especially in natural disasters.
Innovation Solution
A position information distribution server is provided outside the core network, which receives identification and position information from base transceiver stations, switching centers, and HLR, and records a table to specify servers for transmitting this information to position information provision servers, thereby reducing the load on communication carrier facilities and allowing for efficient distribution of position information without increasing the load on existing facilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If position information is transmitted from communication carrier facilities (HLR, switching centers) to multiple position information transmission systems, then position information can be provided to multiple systems, but the load on communication carrier facilities increases
Solution Approach 1:
The patent introduces a position information distribution server as an intermediary component that receives position information from communication carrier facilities (HLR, switching centers) and distributes it to multiple position information provision servers. This mediator architecture allows the core network facilities to communicate with only one distribution server, thereby preventing load increase on HLR and switching centers even when multiple provision servers are operated.
2Productivity
If the number of position information transmission systems increases, then more position information services can be provided, but communication lines may become congested and disrupt other services
Solution Approach 1:
The patent segments the position information transmission architecture into three distinct layers: (1) communication carrier facilities (HLR, switching centers) that generate position information, (2) a position information distribution server that acts as a dedicated transmission hub, and (3) multiple position information provision servers that deliver information to end users. This segmentation isolates the core network from direct interaction with multiple service systems, ensuring that increased service capacity does not congest communication lines or disrupt other services.

AI summary
A position information distribution server includes: a communication unit that is provided outside a core network and receives identification information of a cellular phone and position information of the cellular phone from base transceiver stations, switching centers, VLRs, or an HLR; and a recording unit that records a first table including information to specify a server transmitting the position information among position information provision servers, for each identification information of the cellular phone. The position information provision servers are servers that provide position information services for transmitting the position information transmitted from the position information distribution server to information terminals. When the communication unit receives the identification information and the position information of the cellular phone, the communication unit transmits the identification information and the position information of the cellular phone to a server shown in the first table among the position information provision servers.
