Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, it should be noted that in adding reference numerals to the components of each drawing, the same components are given the same reference numerals as much as possible even though they are indicated on different drawings. In addition, in describing the present invention, if it is determined that a detailed description of a related known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted. In addition, preferred embodiments of the present invention will be described below, but the technical spirit of the present invention is not limited thereto and may be variously implemented by those skilled in the art without being limited thereto.

Modems to which the latest technology, Voice over Long-Term Evolution (VoLTE) are applied, are increasingly being used in telematics systems in vehicles.

However, in the case of North America, which has a large land area, 3G coverage is still wide, and LTE coverage is still under construction. In addition, SvLTE (Simultaneous voice LTE) method is used instead of LTE as VoLTE, and it is expected to be used as SvLTE until 2020 when the 3G network is demolished. That is, data communication is used in LTE network and voice calls are used in 3G network.

An object of the present invention is to flexibly configure LTE according to LTE support policy according to the policy of each country's telecommunication company.

For example, in the case of Verizon in North America, users must manually set up VoLTE at that time according to the 3G network demolition policy following the introduction of the LTE network. 4 is an exemplary diagram illustrating a VoLTE setting change screen. In smartphones, VoLTE is called HD voice, and in smartphones that support VoLTE, the user must manually set it.

In order to solve this problem, the present invention proposes a method for actively and efficiently setting a corresponding setting using a telematics center.

The resulting effects are as follows.

First, the network network is set up automatically by interworking with the center without user setting.

Second, in the case of a mobile phone, the user must set it arbitrarily, but in the case of telematics, the customer does not need to recognize or manipulate the setting.

Third, it is possible to prevent unnecessary standby current consumption of the vehicle by actively turning off the modem not in use.

Fourth, according to the settings sent from the center without user manipulation, the settings are automatically lowered to the vehicle's telematics terminal at the required time, which makes it possible to respond to HD-quality high-quality calls, fast call connection time, and the removal of 3G networks.

Each configuration constituting the telematics system 100 for a vehicle described above has been described. In this embodiment, such a vehicle telematics system 100 operates as follows.

A vehicle usually uses two modems as a modem for wireless communication, one is a 3G modem 154 and the other is an LTE modem 155 .

In the case of a vehicle equipped with a telematics system, when the vehicle enters a standby state after turning off the engine, in most cases, it enters a standby state for a certain period of time (ex. 96 hours) in the minimum power mode for remote service. At this time, in the vehicle, only the 3G modem 154, which is widely used, is turned on in order to reduce standby consumption current (dark current). The reason is to receive a message (SMS or packet) from the center-side server 120 of the remote service.

When the vehicle starts, the 3G modem 154 is first turned on and then communicates with the telematics center server 120 . In this case, the head unit 140 of the vehicle transmits services such as driving information, diagnostic information, vehicle status, and regular inspection to the center server 120 .

In addition, the head unit 140 transmits communication network information currently used by the vehicle, such as current location information of the vehicle and currently connected network information, obtained through the GPS receiver 158 to the center server 120 . For example, the head unit 140 transmits the communication network information in the form of "latitude 42.1234, longitude -83.1234, connection network 3G, connection success".

The telematics center side server 120 receives the location information of the vehicle and checks whether VoLTE network support in the vicinity of the area is supported through VoLTE coverage information of the telecommunication company. If the vehicle has a corresponding location in the VoLTE coverage information of the telecommunication company, the center server 120 requests the head unit 140 of the vehicle to set LTE Preferred.

After receiving VoLTE Preferred, the head unit 140 attempts to change to the corresponding setting. If the VoLTE network connection fails, the head unit 140 rolls back again, connects to 3G, and transmits the failure information along with the location to the telematics center server 120 .

The telematics center side server 120 obtains statistical information on the success/failure of VoLTE network connection for each vehicle through the corresponding information, thereby making it possible to construct BIG DATA.

In addition, the telematics center side server 120 transmits probability information on VoLTE success and failure information for each vehicle to the communication network company server 110 to request coverage. Here, x % is the standard probability of supporting some networks, and y % is the standard probability of supporting the entire network. The standards of x % and y % follow the Telematics Center policy. For example, if x is 90% and y is 99%, it means that VoLTE connection is successful with a 90% probability based on some support criteria, and it means that the connection will succeed with a 99% probability based on all support criteria.

In North America, if it becomes effective to operate with VoLTE after 2020, the network will set the VoLTE Preferred (4G network priority connection) setting. The setting is a state in which the 3G modem 154 and the VoLTE modem 155 are turned on and on standby in the standby mode. At the time of initial booting, the network is connected to the network with VolTE first, and if it fails, it is connected to 3G. As the 3G network is gradually removed at that time, it is a temporary connection method.

When 3G is completely removed from the communication network operator, the use of the 3G modem 154 is no longer necessary because it consumes standby power. If the vehicle head unit 140 sends the VoLTE Preferred to the center server 120, the telematics center now responds with VoLTE Only.

In this case, the head unit 140 completely turns off the 3G modem 154 and operates only the VoLTE modem 155 in standby mode or operation mode to prevent unnecessary standby power consumption. Since it operates only with VoLTE, it operates as LTE with Voice.

2 is a reference diagram for explaining a method of setting a communication network to be used by a head unit of a vehicle based on a location. The following description refers to FIGS. 1 and 2 .

The head unit 140 first accesses the second server 120 through the 3G network 210 to obtain communication network information about the current location.

If it is determined based on the communication network information that the coverage at the current location does not support VoLTE ( 241 ), the head unit 140 continues to use the 3G network 210 to perform wireless communication such as data communication and voice call. do.

On the other hand, when it is determined that the coverage at the current location supports VoLTE and the success rate is x% or more based on the communication network information (244), the head unit 140 changes the wireless communication mode to the VoLTE Preferred (220).

Thereafter, the head unit 140 changes the communication network to be used to the VoLTE network ( 242 ). When the communication network to be used is normally changed to the VoLTE network, the head unit 140 uses the VoLTE network for data communication and the 3G network 210 for voice calls. On the other hand, if the communication network to be used is not normally changed to the VoLTE network, the head unit 140 notifies the server of the connection failure ( 247 ), and performs wireless communication using the 3G network 210 .

Meanwhile, when it is determined that the coverage at the current location supports VoLTE and the success rate is y% or more based on the communication network information (245), the head unit 140 changes the wireless communication mode to VoLTE Only (230).

Thereafter, the head unit 140 changes the communication network to be used to the VoLTE network ( 243 ). When the communication network to be used is normally changed to the VoLTE network, the head unit 140 uses the VoLTE network for both data communication and voice calls. On the other hand, if the communication network to be used is not normally changed to the VoLTE network, the head unit 140 notifies the server of the connection failure ( 248 ) and changes the mode to VoLTE Preferred ( 220 ).

On the other hand, if the current mode is VoLTE Preferred (220) and it is determined that the coverage at the current location supports VoLTE and the success rate is y% or more (246), the head unit 140 changes the mode to VoLTE Only (230). .

3 is a table diagram for explaining the types of communication networks that can be changed by the head unit of the vehicle. The following description refers to FIGS. 1 to 3 .

3G is an example of a case in which the head unit 140 performs wireless communication using the 3G mode 210 . That is, this is an example of a case in which the head unit 140 communicates using the 3G network for both data communication and voice communication.

And the LTE partial network is an example of a case in which the head unit 140 performs wireless communication using the VoLTE Preferred mode 220 . That is, the head unit 140 uses an LTE network for data communication and a 3G network for voice calls.

Also, the entire LTE network is an example of a case in which the head unit 140 performs wireless communication using the VoLTE Only mode 230 . That is, it is an example of a case in which the head unit 140 performs wireless communication using the LTE network for both data communication and voice communication.

5 is a flowchart illustrating a method of operating the telematics system for a vehicle according to the first embodiment of the present invention.

First, the vehicle head unit 140 waits for 3G (S505).

Thereafter, the head unit 140 executes a remote service (S510).

When the vehicle ignition is set to ON (S515), the head unit 140 transmits the vehicle network connection state information to the second server 120 provided at the center side (S520).

Thereafter, the head unit 140 acquires communication network information at the current location from the second server 120 .

Thereafter, the head unit 140 determines whether it is possible to use the LTE network for each data communication and voice call during wireless communication based on the communication network information (S525).

If it is determined that it is impossible to use the LTE network for both data communication and voice communication, the head unit 140 sets the vehicle wireless communication to the 3G mode (S530) and then uses the 3G network for data communication and voice communication (S535).

On the other hand, if it is determined that it is possible to use the LTE network only for data communication, the head unit 140 sets the vehicle wireless communication to VoLTE Preferred mode (S540) and uses the LTE network for data communication and the 3G network for voice calls ( S545).

Meanwhile, if it is determined that it is possible to use the LTE network for both data communication and voice call, the head unit 140 sets the vehicle wireless communication to VoLTE Only mode (S550) and uses the LTE network for both data communication and voice call (S555) .

After that, when the vehicle's engine is turned OFF (S560), when the vehicle wireless communication mode is the 3G mode, the head unit 140 sets only the 3G modem to the standby mode and turns the LTE modem OFF (S565).

On the other hand, when the vehicle wireless communication mode is the VoLTE Preferred mode, the head unit 140 sets both the 3G modem and the LTE modem to the standby mode (S570).

Meanwhile, when the vehicle wireless communication mode is the VoLTE Only mode, the head unit 140 turns off the 3G modem and sets the LTE modem to the standby mode (S575).

6 is a flowchart illustrating a method of operating a telematics system for a vehicle according to a second embodiment of the present invention.

First, the head unit 140 of the vehicle maintains the standby state in the last network connection state (S605). Usually the default value is 3G.

Meanwhile, the first server 110 built in the communication network company transmits VoLTE coverage information to the second server 120 built in the telematics center.

Thereafter, when the vehicle's ignition is turned on (S610), the head unit 140 executes a telematics service (S615).

Thereafter, the head unit 140 transmits the GPS-based vehicle current location information and the last network connection information to the telematics center (S620).

Thereafter, the head unit 140 determines whether the current location of the vehicle is within the VoLTE coverage provided by the communication network company and has succeeded with a probability greater than or equal to x% ( S625 ).

If it is determined that the current location of the vehicle is not located in the VoLTE coverage or has not succeeded with an x% probability or more, the head unit 140 sets the wireless communication mode of the vehicle to the 3G mode (S630).

On the other hand, if the current location of the vehicle is located in VoLTE coverage and it is determined that success is greater than or equal to x% probability, it is determined whether the head unit 140 has succeeded with probability greater than or equal to y% (S635). y has a greater value than x.

If it is determined that the success rate is greater than or equal to y%, the head unit 140 sets the vehicle's wireless communication mode to the VoLTE Preferred mode (S640).

On the other hand, if it is determined that the success rate is greater than or equal to y%, the head unit 140 sets the vehicle's wireless communication mode to the VoLTE Only mode (S645).

After that, when the vehicle's engine is turned OFF (S650), when the vehicle's wireless communication mode is the 3G mode, the head unit 140 sets only the 3G modem to a standby state and turns off the LTE modem (S655).

When the vehicle's wireless communication mode is VoLTE Preferred mode, the head unit 140 sets both the 3G modem and the LTE modem to standby (S660). Turn off the modem and set only the LTE modem to the standby state (S665).
