It takes time and effort. Further, when the number of registered phone book data is large, it takes a lot of time to acquire the phone book data. Furthermore, here, it is assumed that the mobile phone and the business phone system slave unit are fixedly associated with each other, and multiple employees share a plurality of business phone system slave units as in a free address office. In this case, every time you use the handset, it is necessary to operate the handset of the business phone system and obtain all the phone book information of the mobile phone. There is a risk of leakage.

  If the transmission method described in Patent Document 4 is used, the telephone directory data in a predetermined format can be transmitted from the mobile phone to the terminal of the business phone system each time the call is made, and the transmission can be performed from the terminal of the business phone system. However, here, both the mobile phone and the business phone system terminal need to have the same short-range communication protocol, and the types of mobile phones that can be used are limited. In addition, it is not common for a terminal of a business phone system to implement a short-range communication function, and the implementation of this function leads to an increase in the cost of the terminal of the business phone system. Also, even if both the mobile phone and business phone system terminals have the same short-range communication protocol, it is necessary to connect the two with a wire in the case of a wired connection, and pair them together in the case of a wireless connection. Is necessary, so it takes time. In addition, when multiple employees share multiple business phone system terminals, such as in a free address office, it is necessary to change the connection between the two when using the telephone, and in the case of a wired connection, In this case, since it is necessary to change the pairing destination of both, it takes time.
