Abstract
An in-vehicle handsfree apparatus stores a mail operation state while a message access profile (MAP) is being connected with a cellular phone. An incoming voice call from a communication network arises in the cellular phone while the in-vehicle handsfree apparatus is receiving mail information from the cellular phone. When the cellular phone answers the incoming voice call, the MAP is disconnected from the cellular phone. After completing the handsfree call relative to the incoming voice call, the reception of the mail information is resumed from the state just before the MAP was once disconnected.
Claims5
An in-vehicle apparatus having a handsfree function, the apparatus comprising:
- a connecting section configured to establish a concurrent connection of a handsfree call protocol and a data transfer protocol, the handsfree call protocol being for a handsfree call with a cellular phone, the data transfer protocol being for a data transfer with the cellular phone;
- a storing section configured to store a data transfer state when the connection of the data transfer protocol with the cellular phone is being established by the connecting section;
- and
- a control circuit configured to
- store an interrupt event, which indicates that the connection of the data transfer protocol becomes interrupted at a time during the data transfer, by determining the data transfer state, which is stored by the storing section, in case that an operation in the cellular phone causes an interruption of the connection of the data transfer protocol, which was connected under the concurrent connection with the cellular phone established by the connecting section with respect to the handsfree call protocol and the data transfer protocol,
- establish a re-connection of the data transfer protocol when a predetermined condition is satisfied, and
- resume the date transfer from a just-prior-interrupt data transfer state, which corresponds to a data transfer state just before the connection of the data transfer protocol was interrupted.
A method for resuming a data transfer in an in-vehicle apparatus having a handsfree function, the method comprising:
- establishing a concurrent connection of a handsfree call protocol and a data transfer protocol, the handsfree call protocol being for a handsfree call with a cellular phone, the data transfer protocol being for a data transfer with the cellular phone;
- storing a data transfer state when the connection of the data transfer protocol with the cellular phone is being established;
- storing an interrupt event, which indicates that the connection of the data transfer protocol becomes interrupted in a mid process of the data transfer, by determining the stored data transfer state, in case that an operation in the cellular phone causes an interruption of the connection of the data transfer protocol, which was connected under the concurrent connection with the cellular phone with respect to the handsfree call protocol and the data transfer protocol;
- establishing a re-connection of the data transfer protocol when a predetermined condition is satisfied;
- and
- resuming the date transfer from a just-prior-interrupt data transfer state, which corresponds to a data transfer state just before the connection of the data transfer protocol was interrupted.
