Abstract

In a wireless communication system, a vehicle communication apparatus and a portable communication apparatus provide service in cooperation. Both the apparatuses execute in cooperation each of a first application and a second application. When switching from the first application to the second application, a connection destination of a specific profile used in both the apparatuses is switched from the first application to the second application. This improves the connection of profiles.

Claims

1. A wireless communication system comprising:

a vehicle communication apparatus that includes

an in-vehicle application execution device operable to execute an application, and

an in-vehicle profile connection device that connects one or more profiles; and

a portable communication apparatus that includes

an in-portable application execution device operable to execute an application, and

an in-portable profile connection device that connects one or more profiles,

the wireless communication system connecting a first profile that specifies short-range wireless communication of data between the in-vehicle profile connection device and the in-portable profile connection device even when the in-vehicle application execution device and the in-portable application execution device execute in cooperation any one of a first application and a second application,

the wireless communication system further comprising;

a determination device that determines a switching request of an executing state of an application; and

a profile connection control device that controls connection of one or more profiles between the in-vehicle profile connection device and the in-portable profile connection device,

wherein

when the determination device determines a switching request from a first executing state to a second executing state,

the first executing state in which a first application is executed in cooperation by the in-vehicle application execution device and the in-portable application execution device,

the second executing state in which a second application is executed in cooperation by the in-vehicle application execution device and the in-portable application execution device,

the profile connection control device switches

from a connection of the first profile by the first application between the in-vehicle profile connection device and the in-portable profile connection device

to a connection of the first profile by the second application between the in-vehicle profile connection device and the in-portable profile connection device.

2. The wireless communication system according to claim 1, wherein

when the determination device determines the switching request from the first executing state to the second executing state, the profile connection control device disconnects a second profile which is currently connected between the in-vehicle profile connection device and the in-portable profile connection device, the second profile becoming unnecessary in the second executing state.

3. The wireless communication system according to claim 2, wherein

after disconnecting the second profile in case that the determination device determines the switching request from the first executing state to the second executing state, the profile connection control device reconnects the second profile when the determination device determines a switching request from the second executing state to the first executing state.

4. The wireless communication system according to claim 1, wherein

the determination device determines the switching request between the first executing state and the second executing state according to ON or OFF of a vehicle power source.

5. The wireless communication system according to claim 1, wherein

the determination device determines the switching request between the first executing state and the second executing state according to a manipulation by a user to the vehicle communication apparatus or the portable communication apparatus.

6. The wireless communication system according to claim 1, wherein

the short-range wireless communication is a wireless communication with Bluetooth.

7. The wireless communication system according to claim 6, wherein

the first profile is an SPP (Serial Port Profile).

8. A vehicle communication apparatus comprising:

an in-vehicle application execution device operable to execute an application;

an in-vehicle profile connection device operable to connect a profile with an in-portable profile connection device of a portable communication apparatus; and

a determination device that determines a switching request of an executing state of an application,

the vehicle communication apparatus further comprising

an in-vehicle profile connection control device that controls connection of a profile between the in-vehicle profile connection device and the in-portable profile connection device,

wherein

when the determination device determines a switching request from a first executing state to a second executing state,

the first executing state in which a first application is executed in cooperation by the in-vehicle application execution device and the in-portable application execution device,

the second executing state in which a second application is executed in cooperation by the in-vehicle application execution device and the in-portable application execution device,

the in-vehicle profile connection control device switches

from a connection of a first profile by the first application between the in-vehicle profile connection device and the in-portable profile connection device

to a connection of the first profile by the second application between the in-vehicle profile connection device and the in-portable profile connection device.

9. A portable communication apparatus comprising:

an in-portable application execution device operable to execute an application; and

an in-portable profile connection device operable to connect a profile with an in-vehicle profile connection device of a vehicle communication apparatus,

the portable communication apparatus further comprising

an in-portable profile connection control device that controls connection of a profile between the in-vehicle profile connection device and the in-portable profile connection device,

wherein

when detecting a switching request from a first executing state to a second executing state,

the first executing state in which a first application is executed in cooperation by the in-vehicle application execution device and the in-portable application execution device,

the second executing state in which a second application is executed in cooperation by the in-vehicle application execution device and the in-portable application execution device,

the in-portable profile connection control device switches

from a connection of a first profile by the first application between the in-vehicle profile connection device and the in-portable profile connection device

to a connection of the first profile by the second application between the in-vehicle profile connection device and the in-portable profile connection device.
