Problems solved by technology

However, because the vehicle-mounted device may be connected with a plurality of portable phones, if the phone book information is stored in the vehicle-mounted device according to each paired portable phone, a large amount of storage space is required for storage, and a large amount of update operations are required to ensure that the information in the vehicle-mounted device is stored. accuracy of information
In addition, in consideration of privacy, information security, etc., many people do not want to save their phonebooks in the vehicle equipment, especially for some non-personal vehicles (such as company vehicles, business vehicles, etc.), the driver does not Not fixed, in this case, it is even more undesirable to save personal phonebook information in the car device

Embodiment 1

[0056] Below, refer to figure 1 , the composition of the in-vehicle device 1 of the present invention and the phone 2 (first wireless communication device) and phone 3 (second wireless communication device) connected to the in-vehicle device 1 (display device) will be described.

[0057] Such as figure 1 As shown, the in-vehicle device 1 includes at least an input unit 11 , a telephone number acquisition unit (identifier acquisition unit) 12 , a user name acquisition unit 13 , a display unit 14 , and a pairing information table 15 . In addition, the phone 2 connected to the vehicle-mounted device 1 includes a Bluetooth communication unit 21, a local number storage unit 22, a Bluetooth table 23 and a phonebook table 24, and the phone 3 connected to the vehicle-mounted device 1 also includes a Bluetooth communication unit 31, a local number storage unit 32 , bluetooth table 33 and phone book table 34 .

[0058] The input unit 11 is used to receive various commands from the use...

Deformed example 1

[0104] also, figure 1 The in-vehicle device 1 includes a pairing information table 15, and information such as a user name and a telephone number is stored and managed in the pairing information table 15. In fact, in the case where the vehicle-mounted device 1 can be connected to multiple mobile phones at the same time, the present invention can be further simplified by not storing user names and phone numbers in the pairing information table 15 .

[0105] At this time, in the case that the phone 2 and the phone 3 are connected to the vehicle-mounted device 1 at the same time (step S21: Yes), the phone 2 and the phone 3 respectively execute Figure 13 treatment shown. The in-vehicle device 1 obtains the local phone number of the phone 2 from the phone 2 (step S22), and then does not store the phone number, but directly uses the phone number to search for a corresponding phone number in the phone book table 34 of the phone 3 ( Step S23), and display the searched user name of ...

[0108] Figure 14 yes means Figure 8 Flowchart of a modified example of the user name acquisition process in . When the user name obtaining unit 13 obtains the user name, it is not like Figure 10 That accesses the contents of the phonebook based on the phonebook access protocol PBAP, but receives all information of the phonebook table from the connected mobile phone based on the object push protocol OPP, and then retrieves the user name in the received phonebook table.

[0109] The status of Pairing Information Table 15 is Image 6 The status shown, and the phone with the Bluetooth address "00:00:00:00:00:06" ( figure 1 The case where the phone 3) in the mobile phone 3) establishes a connection with the in-vehicle device will be described as an example.

[0110] exist Figure 8 In Step S12, the telephone number acquisition unit 12 acquires the telephone number "133-1111-1112".

[0111] Next, in step S134 , based on the Object Push Protocol OPP, the user name acquisitio...

Abstract

The invention provides a display device and a display method. Wireless communication devices which are connected with the display device can be more clearly displayed. The display device can be connected with more than one wireless communication device. The display device is characterized by comprising an identifier acquisition part which acquires the user identifier of the first wireless communication device from the first wireless communication device connected with the display device; a username acquisition part which acquires a username corresponding to the user identifier from a user information table stored in the second wireless communication device based on the user identifier; and a display part which displays information including the username to act as display information of the first wireless communication device.

Description

technical field [0001] The present invention relates to a display device and a display method, in particular to a display device with a short-range wireless communication function, and a display method used when the display device displays a wireless communication device connected based on a short-range wireless communication method. Background technique [0002] In recent years, Bluetooth technology, one of short-range wireless communication technologies, has been widely used in mobile phones, Bluetooth headsets, PDAs, and vehicle-mounted equipment, especially in the automotive field. Hands-Free Profile (HFP: Hands-Free Profile) based on Bluetooth technology , the portable phone can be controlled through a headset with bluetooth function, vehicle-mounted equipment, etc., such as answering, hanging up, rejecting, voice dialing and other operations. [0003] Usually, when the vehicle-mounted device is paired with a mobile phone, the vehicle-mounted device can obtain informati...
