Description

[Technical Field]

[0001] The present disclosure relates to mobile terminals. [Background technology]

[0002] In recent years, various types of content have been generated using generative artificial intelligence (AI) models. A generative AI model is a model that can generate generated results (content) in response to various input generation request information, based on the instructions, context, questions, and output format indicated in the generation request information, and return the generated results as response information. Large language models (hereinafter referred to as "LLMs") are known as generative AI models used in the technical field of natural language processing. In fact, LLMs require a great deal of effort and time for pre-training, and it is difficult to get them to provide completely accurate answers. Therefore, a technology called a Retrieval Augmented Generation system (hereinafter referred to as "RAG system") is known, which aims to reduce the effort and time required for pre-training and provide more accurate answers by providing the LLM with information to be referenced when making an inquiry to the LLM.

[0003] Furthermore, to achieve high-speed access, it is also envisioned that data from the RAG system (i.e., information to be referenced by the LLM) may be stored as a cache in the user's mobile device. For example, it is conceivable to store data that is likely to be used by the RAG system at that time in the mobile device. Patent Document 1 discloses a technology that automatically provides necessary information (e.g., information about nearby stores) to a mobile device according to the location information of the mobile device.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-066581 Summary of the Invention [Problem to be solved by the invention]

[0005] However, unlike stationary computers, mobile devices have a unique problem in that their data storage capacity is limited. However, Patent Document 1 does not consider how to appropriately control the state of data storage while taking into account the fact that data storage capacity is limited.

[0006] Therefore, an object of the present disclosure is to appropriately control the storage state of data while taking into consideration that data storage capacity is limited. [Means for solving the problem]

[0007] The mobile terminal according to the present disclosure includes a location information acquisition unit that acquires location information of the mobile terminal itself, a determination unit that determines, based on the acquired location information, the priority of each of a plurality of reference data to be referenced by a generative AI model and stored on the mobile terminal, and a control unit that controls the storage state of the reference data on the mobile terminal based on the determined priority. [Effects of the Invention]

[0008] According to the present disclosure, it is possible to appropriately control the storage state of data while taking into consideration that data storage capacity is limited. [Brief explanation of the drawings]

[0009] [Figure 1] FIG. 2 is a functional block diagram showing the configuration of a mobile terminal. [Figure 2] FIG. 10 is a flow chart showing a process executed in the mobile terminal. [Figure 3] FIG. 10 is a diagram showing a modified example of the configuration of the mobile terminal. [Figure 4] FIG. 2 is a diagram illustrating an example of a hardware configuration of a mobile terminal. DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, an embodiment of a mobile terminal according to the present disclosure will be described with reference to the drawings. In the following embodiment, a form will be described in which a large language model (LLM) that is mainly used for text generation is used as an example of a generative AI model.

[0011] [Mobile device configuration] FIG. 1 shows a configuration diagram of a mobile terminal 10 according to the present disclosure. As shown in FIG. 1, the mobile terminal 10 includes a location information acquisition unit 11, a determination unit 12, a control unit 13, a reference database (reference DB) 20, and an LLM 30 in order to perform the functions according to the present disclosure. The mobile terminal 10 is a device that constitutes the RAG system described above. The RAG system is a system that, when issuing a generation request to an LLM based on an instruction statement (generation request information), searches in advance for reference data to be referenced by the LLM, outputs the obtained reference data to the LLM together with the instruction statement, and then obtains the generation result from the LLM and outputs it to the user.

[0012] Furthermore, various types of portable terminals (smartphones, mobile phones, portable notebook computers, smart watches, wearable terminals, etc.) can be used as hardware for the mobile terminal 10. The functions of each unit will be described below.

[0013] The reference DB 20 is a database for storing various reference data to be referenced by the LLM 30. The reference DB 20 stores, for example, Tokyo restaurant data 21 including various information about restaurants in Tokyo (such as information about recommended restaurants and information about newly opened restaurants), Kyoto restaurant data 22 including various information about restaurants in Kyoto, and Kyushu restaurant data 23 including various information about restaurants in Kyushu, and the control related to the storage state of these data will be described later with reference to FIG. 2.

[0014] The LLM 30 is also included in the mobile terminal 10. This configuration can be realized, for example, by installing an application that executes the functions of the LLM 30 on the mobile terminal 10. Note that a configuration may be adopted in which the mobile terminal 10 does not include the LLM 30 and instead interacts with an external LLM 30 (for example, on a network cloud), and this configuration will be described later with reference to FIG. 3.

[0015] The location information acquisition unit 11 is a functional unit that acquires location information of its own mobile terminal. The location information acquisition unit 11 acquires at least one of current location information and future location information as location information of the mobile terminal. In this embodiment, the location information acquisition unit 11 acquires both current location information and future location information as location information of the mobile terminal. The location information acquisition unit 11 acquires current location information from location registration information (location information) of its own mobile terminal 10, GPS (Global Positioning System) positioning information, etc.

[0016] On the other hand, for future location information, the location information acquisition unit 11 acquires future location information estimated based on at least one of the user's planned activity information (including business and personal activity plans such as business trips, travel, and outings) of the mobile terminal 10, past location information history, and the user's ticket purchase history and accommodation reservation history related to location fluctuations. The user's planned activity information may be information entered by the user into a schedule management application or information obtained from text such as an email entered by the user. For example, if the user's planned activity information includes "information about a business trip to Sendai tomorrow," "Sendai" is acquired as future (tomorrow) location information. Also, if it is determined from the past location information history that the user travels on business to Osaka every Tuesday, "Osaka" is acquired as the location information for every Tuesday. Future location information is also acquired from the ticket purchase history and accommodation reservation history. For example, if you have a history of purchasing a round-trip Shinkansen ticket between Tokyo and Nagoya for the day after tomorrow, "Nagoya" will be acquired as your future location information (the day after tomorrow), and if you have a history of booking a hotel stay in Hiroshima from Monday to Friday next week, "Hiroshima" will be acquired as your future location information (Monday to Friday next week).

[0017] The determination unit 12 is a functional unit that determines, based on the acquired location information, the priority of each of various reference data (reference data to be referred to by the LLM 30) stored in the reference DB 20. Details will be described in the processing description of FIG. 2.

[0018] The control unit 13 is a functional unit that controls, based on the determined priority, the storage state of the reference data in the mobile terminal 10. Details will be explained in the processing explanation of FIG.

[0019] [Processing Executed on the Mobile Terminal 10] The process executed in the mobile terminal will be described below with reference to Fig. 2. First, the location information acquisition unit 11 in the mobile terminal 10 acquires both current location information and future location information as location information of the mobile terminal 10, as in the example described above (step S1).

[0020] Next, the determination unit 12 determines the priority of each of the various reference data (reference data to be referred to by the LLM 30) stored in the reference DB 20 based on the acquired location information (step S2). I stayed in Kyushu for a week until yesterday. I will be staying in Tokyo today and tomorrow. -Let's say you plan to stay in Kyoto from the day after tomorrow. In such a situation, the determination unit 12 determines a higher priority than a predetermined first criterion for determining that reference data (Kyoto restaurant data 22) related to the acquired future location information (Kyoto) should be saved. The determination unit 12 determines a lower priority than a predetermined second criterion for determining that reference data (Kyushu restaurant data 23) related to an absence location (Kyushu) where the user is estimated to be out of the vicinity based on the acquired future location information, based on the acquired future location information. The determination unit 12 also determines a higher priority than the above-mentioned first criterion (criterion for determining that data should be saved) for reference data (Tokyo restaurant data 21) related to a stay location (Tokyo) where the user habitually stays for long periods of time based on the location information. The first criterion and the second criterion may be the same value.

[0021] Next, the control unit 13 controls the storage state of the reference data in the mobile terminal 10 based on the determined priority (step S3). In the above example, the control unit 13 determines a lower priority for the reference data (Kyushu restaurant data 23) related to the absence location (Kyushu) than the second criterion for determining that storage is unnecessary, so the control unit 13 deletes the reference data (Kyushu restaurant data 23) related to the absence location (Kyushu) from the reference DB 20 based on the determined priority and the second criterion. Also, the control unit 13 determines a higher priority for the reference data (Kyoto restaurant data 22) related to the future location information (Kyoto) than the first criterion for determining that storage is necessary, so the control unit 13 downloads the reference data (Kyoto restaurant data 22) related to the future location information (Kyoto) in advance and stores it in the reference DB 20 based on the determined priority and the first criterion. Furthermore, since a higher priority than the first criterion was determined for the reference data (Tokyo restaurant data 21) related to the location (Tokyo) where customers habitually stay for long periods of time, the control unit 13 continues to store the reference data (Tokyo restaurant data 21) related to the location (Tokyo) where customers habitually stay for long periods of time in the reference DB 20 based on the priority and the first criterion (maintaining the stored state).

[0022] According to the embodiment described above, the data storage state can be appropriately controlled while taking into account the fact that data storage capacity is limited. In particular, by controlling data based not only on current location information but also on estimated future location information, data that no longer needs to be stored (Kyushu restaurant data 23 in the above example) can be quickly determined and deleted to free up data storage capacity, and data that is expected to need to be stored (Kyoto restaurant data 22 in the above example) can be downloaded and stored in advance. Of course, the storage state of data from locations where data habitually remains for long periods of time (Tokyo restaurant data 21 in the above example) is appropriately maintained. In this way, the data storage state can be extremely appropriately controlled on a mobile device with a limited data storage capacity.

[0023] In addition, it is possible to obtain future (the current day or tomorrow) location information from work schedules previously input by truck delivery companies, hire car / taxi drivers, construction companies, sales representatives, etc., and to download and save appropriate reference data in advance to the mobile terminal 10 according to the obtained future location information.

[0024] The configuration of the mobile terminal 10 is not limited to the configuration shown in Fig. 1. For example, as shown in Fig. 3, the LLM 30 (generative AI model) may exist outside the mobile terminal 10 (for example, on a network cloud) rather than inside the mobile terminal 10.

[0025] The gist of the present disclosure lies in the following [1] to [6]. [1] A location information acquisition unit that acquires location information of the mobile device itself; a determination unit that determines the priority of each of a plurality of reference data to be referenced by the generative AI model and stored in the mobile terminal based on the acquired location information; a control unit that controls a storage state of the reference data in the mobile terminal based on the determined priority; A mobile terminal comprising: [2] The mobile terminal according to [1], wherein the location information acquisition unit acquires at least one of current location information and future location information as the location information of the mobile terminal.
