する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to private electronic branch exchanges, and in particular, to CCITT Recommendation I.
This invention relates to a service selection method when a called terminal is busy via a basic interface or a primary group interface based on series.

ービスが周知技術としである。Conventionally, in non-ISDN networks, between the private electronic branch exchange and the central office exchange, the network is limited to only the information (signals) necessary to connect the calling terminal and the called terminal, such as activation signals and selection signals. There is no way to send information from the calling terminal to the called party's private electronic branch exchange or terminal before the call begins. For this reason, in conventional private electronic branch exchanges, a busy transfer service and an extension representative service are well-known techniques that allow a call to be received by another terminal when the called terminal is busy.

一切できない問題がある。As mentioned above, conventionally, there is no way to send information from the calling terminal to the called side's private branch exchange or terminal before the call starts, so if the called terminal is busy on the called side's private branch exchange or terminal, Because the call is received by another predetermined terminal,
There is a problem in that the calling terminal cannot select any service when the called terminal is busy.

ユーザ情報を使用して前記構内電子交換機に通知する。[1lIII! [Means for Solving the Problems] The service selection method of the present invention when a called terminal is busy is a private electronic branch exchange connected to an ISDN network through a basic interface and a primary group interface according to the CCITT Recommendation I series, so that a terminal can access the ISDN network from the terminal. When calling a terminal housed in the private electronic branch exchange via the private branch exchange, service selection information when the called terminal is busy is sent to the user terminal defined in the I series.
The user information is used to notify the private branch exchange.
次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

次のサービスがある。At this time, the calling terminal 21 sends service selection information to the called terminal 11 in this message, indicating what service you would like to receive when the terminal 14 is busy, based on the CCITT Recommendation I series (1,
451) using the user/user information that has been defined. The private electronic branch exchange 1 identifies the state of the called terminal specified in the received call setup message and, if the called terminal is busy, selects the service selection information specified by the user-to-user information in the call setup message. Provides service when the called terminal is busy. This service includes, for example, the following services:
