FIG. 2 illustrates an electronic device, an access point device, and a plurality of server devices that can be connected to the electronic device to determine time information, according to various embodiments.

The electronic device 200 may be implemented as a variety of portable electronic devices, such as a smartphone or tablet PC. The electronic device 200 may support wireless LAN (or Wi-Fi, wireless fidelity) communication using a wireless communication circuit (e.g., the wireless communication module 192 of FIG. 1), and may support wireless LAN (or Wi-Fi, wireless fidelity) communication with the access point device 260. It can be connected to perform data communication with various external devices.

The access point device 260 provides wireless LAN services to various devices including the electronic device 200, and is connected to another network by wire or wirelessly to transmit/receive information from the electronic device 200. Data can be provided. The access point device 260 has identification information, and the identification information may include a basic service set identifier (BSSID).

The NTP server 270 may provide standard time to the electronic device 200 based on network time protocol (NTP). NTP is a protocol for synchronizing the time of various devices distributed on a network. When the electronic device 200 connects to the network through the access point device 260, it can receive standard time from a designated NTP server 270. . The standard time may be coordinated universal time (UTC) or Greenwich mean time (GMT).

The location service server 280 may provide a geocoding service to the electronic device 200. For example, when the location service server 280 receives latitude and longitude information from the electronic device 200, it provides address information corresponding to the latitude and longitude, or provides address information corresponding to the latitude and longitude from the electronic device 200. When receiving address information, latitude and longitude information corresponding to the address can be provided. Address information may include country information and administrative district information of the electronic device 200, and administrative district information may include a state, city/province, etc. determined for each country.

The time zone service server 290 may receive location information (e.g., latitude and longitude information, address information) from the electronic device 200 and provide time zone information corresponding to the location information. Time zone information may be information about the time zone actually used at the current location. The time zone service server 290 can build a database of map data around the world and time zone information for each location, and provide time zone information corresponding to the location information to the electronic device 200 requesting the service.

Time zones are generally classified according to longitude, but often do not correspond to longitude depending on country and regional boundaries. Additionally, there are cases where one time zone is used per country, and there are cases where one country uses multiple time zones.

In order for the electronic device 200 to obtain the current time at the current location, it is necessary to obtain standard time and time zone information. For example, if the current standard time is 09:00 and the time zone of the current location is GMT+9, the current time can be set to 18:00.

According to one embodiment, the electronic device 200 may support cellular communication. For example, cellular communication may include various mobile communication methods through mobile communication providers such as LTE, LTE-A, CDMA, WCDMA, UMTS, WiBro, and GSM.

When the electronic device 200 is connected to a base station through cellular communication, standard time (UTC or GMT) and time zone information of the current location can be obtained along with cellular network information through network identity and time zone (NITZ). . That is, if the electronic device 200 can connect to a cellular network, it can set the current time by receiving time zone information from the cellular network.

However, if the electronic device 200 does not support cellular communication, or is equipped with a cellular communication module but is in airplane mode or is located in a shaded area and cannot perform cellular communication, the time zone is not connected to the cellular network as described above. It is impossible to obtain information.

Even if the electronic device 200 does not support a cellular network, when using the time zone service server 290, time zone information of the current location can be easily obtained. However, the time zone service server 290 is operated by a 3rd party, so it costs money and processing time can be long. Additionally, because the database of the time zone service server 290 contains a vast amount of data including map data and time zone information for each location, it is difficult to build it in the memory of the electronic device 200.

Hereinafter, in the case where the electronic device 200 does not include a cellular communication module or cannot access a cellular network, various methods are provided to obtain time zone information by minimizing dependence on the time zone service server 290. Examples will now be described.

According to various embodiments, the memory 350 may store a plurality of country information and a third database that maps and stores each country information, the number of time zone information, and default time zone information. Here, the third database may be a file (eg, tzlookup.xml) created in a general-purpose language such as xml.

For example, if a specific country uses only one time zone (e.g., Korea), only one time zone information may be stored, and the default time zone information may be the time zone information of that country. On the other hand, in the case of a country that uses multiple time zones (e.g., America), multiple time zone information may be stored, and any one of the time zones used in the country may be stored as default time zone information.

According to various embodiments, the processor 340 may obtain current location information of the electronic device 300 when an event for setting a time zone occurs. Here, an event for setting the time zone may occur when connected to the access point device through the wireless communication circuit 310.

According to various embodiments, if the electronic device 300 supports cellular communication and is currently connected to a cellular network, an event for setting a time zone may not occur. That is, when the electronic device 300 is connected to a cellular network, the methods of obtaining time zone information, which will be described later, are not performed, but the standard time (UTC or GMT) along with the cellular network information through NITZ (network identity and time zone). ) and time zone information of the current location can be obtained and the current time can be set from this.

According to various embodiments, the electronic device 300 may acquire current location information (eg, latitude and longitude) using the GPS sensor 330. Alternatively, the electronic device 300 may check the location information of the electronic device 300 from a network location provider (NLP) that provides location information to the electronic device 300 based on the location information of the access point device.

When acquiring latitude and longitude information, the processor 340 transmits the latitude and longitude information to a location service server (e.g., the location service server 280 in FIG. 2) and obtains address information corresponding to the latitude and longitude from the location service server. You can. Here, address information may include country information and administrative district information.

According to various embodiments, the processor 340 may check time zone information corresponding to the current location information from the first database and/or the second database stored in the memory 350. According to various embodiments, when time zone information is confirmed from the first database and/or the second database, the processor 340 may determine time information corresponding to the current location information using the confirmed time zone information. According to various embodiments, when time zone information is not confirmed from the first database and/or the second database, the processor 340 requests time zone information from an external time zone service server through the wireless communication circuit 310. Thus, time zone information corresponding to the current location information can be obtained from the time zone service server.

According to various embodiments, when location information is acquired, the processor 340 may check the number of time zone information and default time zone information corresponding to the current location information (e.g., country information) in a third database. As explained previously, one time zone or multiple time zones can be used for each country, and the third database (or file) contains information on multiple countries, the number of each country information and time zone information, and the default time zone. Information can be mapped and stored.

According to various embodiments, the processor 340 may set the current time using the obtained default time zone information when the country where the current location is mapped to one time zone information (e.g., South Korea). The processor 340 may determine time information corresponding to the current location by adding the time of the acquired time zone information to the standard time obtained based on network time protocol (NTP) through the wireless communication circuit 310.

According to various embodiments, when the country where the current location is mapped with a plurality of time zone information (e.g., America), the processor 340 stores the time zone information mapped with the country information and administrative district information of the current location information in the first database. You can check it here. As described above, the first database is information stored on the memory 350 during the manufacturing process of the electronic device 300, and can map and store time zone information by country/administrative region.

According to various embodiments, when time zone information mapped to country information and administrative district information is not confirmed in the first database, the processor 340 uses the identification information of the access point device connected through the wireless communication circuit 310. You can check time zone information. The processor 340 checks the identification information of the connected access point device in the second database, and when the identification information of the access point device is confirmed in the second database, it uses the identification information of the access point device and the mapped time zone information. Time information corresponding to the current location information can be determined.

Since the access point device is generally placed in a fixed location and the distance supported by wireless LAN communication is short, within a few hundred meters, the electronic device 300 determines that it has the same time zone information as the time zone information of the access point device. You can.

According to various embodiments, when the identification information of the currently connected access point device is confirmed in the second database, the processor 340 obtains the location of the access point device stored in the second database using the GPS sensor 330, etc. You can check whether the difference in current location is within the first standard distance (e.g. 50km). If the difference is within the first reference distance, the location of the access point device has not moved a long distance, and time information can be determined using time zone information mapped to the corresponding access point device in the second database. According to various embodiments, if the difference is greater than the first reference distance, that is, if it is confirmed that the location of the access point device has moved a long distance, the access point closest to the current location of the electronic device 300 in the second database as described later. A process of checking the point device may be performed. According to various embodiments, the processor 340 may perform wireless communication if, as a result of checking the second database, the identification information of the currently connected access point device is not confirmed in the second database. Identification information of at least one access point device can be confirmed from the list of access point devices that have been connected to or searched for the circuit 310. For example, when a wireless LAN connection is triggered, the processor 340 may obtain identification information (eg, BSSID) of adjacent access point devices and store this in the memory 350. At this time, the processor 340 may store location information of each access point device based on location information obtained from a network location provider (NLP) server that provides location information of the access point device. The processor 340 may check the location information of at least one access point device most recently connected or most recently searched from the list of identification information of the access point device stored in the memory 350 through a previous search process.

The processor 340 may check location information of the most recently connected (or discovered) access point device and check whether the distance from the current location is within a first reference distance (eg, 50 km). As a result of the confirmation, if it is within the first reference distance, time information corresponding to the current location information can be determined using time zone information mapped to the identification information of the most recently connected or searched access point device in the second database. This takes into account that the current travel distance is not large after checking the time zone information using a previously connected access point device, so it is expected to be in the same time zone.

According to various embodiments, when the distance between the most recently connected access point device and the current location of the electronic device 300 is greater than the first reference distance, the processor 340 determines the current location of the electronic device 300 in the second database. You can check the closest access point device.

If the distance to the confirmed nearest access point device is within the second standard distance (e.g., 50 km), the processor 340 uses the identification information and mapped time zone information of the confirmed nearest access point device to determine the current location. Time information corresponding to the information can be determined.

According to various embodiments, the processor 340 operates the wireless communication circuit 310 when there is no access point device located within a second reference distance from the current location of the electronic device 300 among the access point devices included in the second database. ), you can obtain time zone information by requesting time zone information from the time zone service server.

That is, when the electronic device 300 cannot confirm the time zone of the current location using the first database and the second database stored in the memory 350, the time zone service server (e.g., the time zone service server of FIG. 2) You can request time zone information from (290)).

In the above, various methods for the processor 340 to obtain time zone information have been described. For example, when time zone information is not obtained through the first database, time zone information is obtained through the second database. , If the time zone information is not obtained through the second database, it is explained that the time zone information is obtained through the time zone service server. However, the various embodiments of this document are not limited to this, and there is no need to use another method on the condition that time zone information is not obtained using one method. For example, the processor 340 may obtain time zone information only by relying on the second database, without using the first database. Alternatively, if time zone information is not obtained from the first database, the processor 340 selects at least one belonging to the second database from the list of directly connected or searched access point devices without confirming the identification information of the currently connected access point device. Access point devices can be checked, and time zone information corresponding to the current location can be determined using the identification information of the closest access point device and the mapped time zone information.
