Innovation Solution
A mobile terminal equipped with a communication unit, input unit, and location information unit, which allows for the selection, transfer, and management of location information as separate files or embedded within messages, using various methods such as GNSS, cell ID, and wireless LAN-based location sensing, and enables data size reduction and selective transfer based on receiver information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If location information is transferred as separate files or embedded within messages, then the efficiency of location information transfer is enhanced, but the device complexity increases due to multiple transfer methods
Solution Approach 1:
The patent segments location information transfer into multiple independent methods: transferring location information as separate files, embedding it within messages, and providing selection mechanisms. This segmentation allows the system to handle different transfer scenarios independently, improving overall transfer efficiency while maintaining manageable complexity through modular design.
Solution Approach 2:
The patent implements dynamic selection of transfer methods based on receiver information and user preferences. The system can adaptively choose between different transfer approaches (separate file vs. embedded) depending on the communication context, receiver capabilities, and user settings, thereby optimizing transfer efficiency without requiring all methods to be simultaneously active.
2Adaptability or versatility
If location information is transferred selectively based on receiver information, then the adaptability of the system is improved, but the loss of time increases due to selection processing
Solution Approach 1:
The patent implements preliminary configuration of transfer preferences and receiver information storage. User preferences, receiver capabilities, and transfer rules are pre-configured and stored in the system. When location information needs to be transferred, the system quickly retrieves and applies pre-established rules rather than making complex decisions in real-time, thus maintaining high adaptability while minimizing selection processing time.
3Loss of information
If location information is changed to reduce data size, then the loss of information is reduced, but the manufacturing precision of location data decreases
Solution Approach 1:
The patent applies parameter changes to location information by transforming coordinates into different reference systems or formats that reduce data size. The system can convert precise coordinate data into relative position data, use compressed coordinate representations, or transform to local reference frames. These parameter transformations maintain essential location information while reducing data transmission requirements, balancing information retention with data size reduction.

AI summary
The present invention relates to a mobile terminal including an input unit; a communication unit; a location information unit configured to obtain location information related to the mobile terminal; and a controller configured to: receive a message and a recipient through the input unit, determine a location information transfer mode set for the recipient, receive a message transfer command through the input unit, transfer the message with the location information to the recipient through the communication unit in response to the message transfer command, when the location information transfer mode is a first transfer mode, and transfer the message without the location information to the recipient through the communication unit in response to the message transfer command, when the location information transfer mode set to the recipient is a second transfer mode.
