JPS6238058A - Protocol identification system for packet switching network - Google Patents

Abstract

PURPOSE:To identify unifiedly protocols of all subscribers without limit to any subscriber by deciding a specific digit representing the protocol type of a subscriber in a subscriber number accommodated in a packet switching network and using an outgoing/incoming subscriber number transmitted/received at call setting so as to identify the protocol type of the outgoing/incoming subscriber. CONSTITUTION:An outgoing subscriber 101 is connected to a protocol exchange 106 via an outgoing exchange 104 and connected to an incoming subscriber 109 via an incoming exchange 107. Outgoing subscriber numbers 201, 203 and incoming subscriber numbers 202, 204 exist in call setting packets 103, 105, 200 at call setting and digits 205, 206 displaying the protocol kind of each subscriber are included. The outgoing exchange 104 identifies the protocol type in the outgoing/incoming subscriber number of the call setting packet received from the outgoing subscriber 102, and when different, routing to a protocol converter 106 is applied. Further, the protocol converter 106 applies protocol conversion according to the outgoing/incoming protocol type similarly. IN this case, the call is cut off when the combination is impossible for conversion.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a protocol identification system in a packet switching network.

[Conventional technology]

Conventionally, in a packet switching network, a subscriber's protocol type is set and notified in a special field (protocol ID field) of a call setting packet.

[Problem that the invention seeks to solve]

In the conventional protocol type identification method described above.

Because it used a special field in the call setup packet,
Some subscribers do not support it, and some subscribers ignore the packet switching network and use it for special information (JOB number, password) between subscribers. There were some points that made it difficult to treat them uniformly.

Also, the special field (protocol ID field)
Forcing subscribers to do so also had the disadvantage of causing subscribers to lose their freedom.

[Means for solving problems]

According to the present invention, a specific digit indicating the protocol type of the subscriber is provided in the subscriber number of the subscriber accommodated in the packet switching network, and the protocol of the calling subscriber is determined from the calling subscriber number sent and received at the time of call setup. A method for identifying a protocol in a packet switching network is obtained, which is characterized by identifying types.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a diagram of an intermediate method for performing protocol conversion in a packet switching network employing the present invention, and FIG. 2 is a diagram of the digit arrangement of subscriber numbers of calling and receiving subscribers shown in a call setup packet according to the present invention. .

In FIG. 1, reference numeral 101 denotes an originating subscriber, which is connected to a protocol converter 106 via an originating exchange 104 and then to a terminating subscriber 109 via a terminating exchange 107. Also, as shown in FIG. 2, there are call setting buckets (103, 105) at the time of call setting.

200) contains an originating subscriber number (201, 203) and a terminating subscriber number (202, 204), and a digit (205) indicating the protocol type of each subscriber.

206) is included. The originating exchange 104 identifies the protocol type in the originating and receiving subscriber number of the call setup packet received from the originating subscriber 101, and if different, routes the packet to the protocol conversion device 106. The protocol conversion device 106 similarly performs protocol conversion according to the originating and receiving protocol type. At this time, if the combination cannot be converted, the leaf is cut off.

〔Effect of the invention〕

As explained above, the present invention defines a specific digit indicating the protocol type of the subscriber in the subscriber number accommodated in the packet switching network, and uses the calling subscriber number transmitted and received at the time of call setup to person's professional
