Bluetooth Device Search Using Nickname Database for Portable Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for searching neighboring Bluetooth devices in portable terminals with Bluetooth modules face delays and inaccuracies due to the need for repeated address and name acquisition, especially when device names are changed or overlap, leading to difficulties in connecting to desired devices.
Innovation Solution
A method and apparatus that enhance search speed and accuracy by adding a nickname field to the Bluetooth management database, where addresses of neighboring devices are acquired, compared to the database, and nicknames are assigned and registered for devices not found in the database, allowing for unique identification and faster future searches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the portable terminal performs name request signals and waits for responses from neighboring Bluetooth devices every time, then the search can be performed, but the searching operation involves excessive delay
Solution Approach 1:
The patent applies preliminary action by pre-acquiring and storing Bluetooth device addresses and names in a management database before actual connection needs arise. When a connection is required, the system first checks the database for existing entries, avoiding redundant name request signals and waiting periods, thus significantly reducing search time while maintaining accuracy through the pre-stored information
Solution Approach 2:
The patent uses copying by creating a management database that stores copies of Bluetooth device addresses and names. Instead of repeatedly performing name requests and waiting for responses, the system copies the previously acquired information into the database for rapid retrieval, eliminating the time-consuming real-time search process while preserving the accuracy of device identification
2Productivity
If the portable terminal uses existing Bluetooth management database for searched devices, then the search speed improves, but the name accuracy becomes unreliable when device names are changed
Solution Approach 1:
The patent implements feedback by continuously updating the management database with the latest device names and addresses. When a Bluetooth device is searched, the system retrieves the device information from the database and uses it to generate a nickname, which is then stored back in the database. This feedback loop ensures that the database always contains current and accurate device information, resolving the issue of name changes while maintaining fast search speeds
3Reliability
If the portable terminal performs both address acquisition and name acquisition operations every time, then complete device information is obtained, but the search process becomes excessively slow
Solution Approach 1:
The patent applies preliminary action by pre-storing Bluetooth device addresses and names in a management database before actual connection needs arise. When a connection is required, the system first checks the database for existing entries, avoiding redundant name request signals and waiting periods, thus significantly reducing search time while maintaining accuracy through the pre-stored information
Solution Approach 2:

AI summary
Provided are a method and an apparatus for searching neighboring Bluetooth devices in a portable terminal having a Bluetooth module. In the method, addresses of searched neighboring Bluetooth devices are used to determine whether the searched neighboring Bluetooth devices are newly-searched Bluetooth devices. If the searched neighboring Bluetooth devices are newly-searched neighboring Bluetooth devices, name request signals are transmitted to the newly-searched neighboring Bluetooth devices to acquire names of the newly-searched neighboring Bluetooth devices. Names of the newly-searched neighboring Bluetooth devices are created, and the addresses, names and names of the newly-searched neighboring Bluetooth devices are registered in a Bluetooth management database.
