ものである。[! ! Means for Solving the Problem: The route/group control method according to the present invention provides a connection route to a called party requested by a caller via PII, which is each node of a private network.
The originating station sends this relay network selection information to the relay stations, and each relay station recognizes this relay network selection information and makes a decision. The called party is connected to the called party via n connection paths indicated by the network selection information.
この発明は発信者が要求する被呼者への接続経路で最も
経済的でかつ効率的な経路で接続することができる。The present invention allows a caller to connect to a called party through the most economical and efficient connection route required by the caller.

In the figure, 1 is a calling station with a network identifier such as rllllJ, 2 is the next caller connected to the calling station 1, 3 and 4 are relay stations with a network identifier such as r222J and a network identifier such as r333j, and 5 is a network identifier. For example, a terminating station with "444", 6 is connected to this terminating station 5, and the called party is 7m-7.
E is a Dch dedicated line that connects the above-mentioned transmitting station 1, relay station 3, relay station 4, and terminating station 5.

First, when the calling party 2 performs a predetermined operation to call the called party 6, the calling station 1 receives a "call call" message containing the relay network selection information element having the R identifiers r222J, r333J, and r444J shown in FIG. ``Settings'' messages are exclusively for Dch, which is the first relay route! ! It is sent to relay station 3 via T&. As a precaution, relay station 3 recognizes relay station 4 as the next relay station and sends a "call setup" message to relay station 4 via Deh private line 7C. Similarly, this relay station 4 recognizes the final station, terminating station 5''fr, and sends a call setup J message to the terminating station 5 via the Dch dedicated ls7e.Then, the called station 6 A "call setup" message can be received from the receiving station 5.
