In-vehicle apparatus having handsfree function

摘要

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.

主权项

1. An in-vehicle apparatus having a handsfree function, the apparatus comprising:
an operation input section configured to receive an operation input from a user; a connecting section configured to establish a concurrent connection of a handsfree call protocol for a handsfree call and a mail transfer protocol for a mail transfer with a cellular phone; a storing section storing a mail transfer state presently taking place as a present mail transfer state out of a plurality of mail transfer states in performing a mail browse under the concurrent connection of the mail transfer protocol and the handsfree call protocol with the cellular phone, the plurality of mail transfer states being changed based on input operations to the operation input section from the user; a control circuit configured to
store an interrupt event at a time during the mail transfer by determining the present mail transfer state in the storing section, in case that an operation in the cellular phone causes an interruption of the connection of the mail transfer protocol under the concurrent connection of the handsfree call protocol and the mail transfer protocol with the cellular phone, the interrupt event indicating that the connection of the mail transfer protocol becomes interrupted at the time during the mail transfer,establish a re-connection of the mail transfer protocol in case that a predetermined condition is satisfied when the interrupt event is stored, andresume the mail transfer from a just-prior-interrupt data transfer state of the plurality of mail transfer states, the just-prior-interrupt data transfer state being the present mail transfer state stored in the storing section when the re-connection of the mail transfer protocol is established.
