Abstract
Abstract An incoming call transfer terminal for transferring to a third-party terminal a call-setting message coming from a calling terminal. The incoming call transfer terminal receives the call-setting message over a first communication channel from the calling terminal. Given the message, the incoming call transfer terminal generates a new call-setting message destined to the third-party terminal by keeping intact those parts of the original message which are needed to establish a through communication channel from the calling terminal to the third-party terminal ; by also preserving such information unique to the calling terminal as a calling sub-address and a called sub-address to be transmitted unchanged to the third-party terminal ; and by rewriting other parts of the original message to indicate that the call is being transferred from the incoming call transfer terminal. The calling number of the calling terminal is transferred as carried on the calling sub-address, called sub-address or user-user information. The call-setting message thus generated is sent automatically to the third-party terminal over a second communication channel.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
108 words
An incoming call transfer terminal comprising: receiving means for receiving a first call-setting message transmitted from a calling terminal over a first communication channel; call-setting message generating means for generating a second call-setting message by keeping intact those parts of the received first call-setting message which need to be transferred from said calling terminal to a third-party terminal and by rewriting those parts of said first call-setting message which need to be communicated from the called terminal to said third-party terminal; and transmitting means for calling said third-party terminal over a second communication channel by use of said second call-setting message generated by said call-setting message generating means.
Claim 2
Dependent Claim
108 words
An incoming call transfer terminal comprising: receiving means for receiving a first call-setting message transmitted from a calling terminal over a first communication channel; call-setting message generating means for generating a second call-setting message by keeping intact those parts of the received first call-setting message which need to be transferred from said calling terminal to a third-party terminal and by rewriting those parts of said first call-setting message which need to be communicated from the called terminal to said third-party terminal; and transmitting means for calling said third-party terminal over a second communication channel by use of said second call-setting message generated by said call-setting message generating means.
Claim 3
Dependent Claim
74 words
An incoming call transfer terminal according to claim 1, wherein said call-setting message generating means generates said second call-setting message by keeping intact those parts of said received first call-setting message which are needed to establish a through communication channel from said calling terminal to said third-party terminal as well as those parts of said received first call-setting message which are preferred to be transferred unchanged from said calling terminal to said third-party terminal.
Claim 4
Dependent Claim
171 words
An incoming call transfer terminal according to claim 2, wherein said call-setting message generating means generates said second call-setting message by keeping intact those parts of said received first call-setting message which are needed to establish a through communication channel from said calling terminal to said third-party terminal, such as the information transmission capability of the network in question, the type of communicating terminals, and channels to be used; by further keeping intactthose parts of said received first call-setting message which are preferred to be transferred unchanged from said calling terminal to said third-party terminal, such as the information specific to a calling party at said calling terminal including a calling sub-address and a called sub-address; and by rewriting those parts of said received first call-setting message which need to be communicated from said called terminal to said third-party terminal, such as the subscriber number, known as a calling number, of said calling party and the subscriber number, known as a called number, of a called party at said called terminal.
Claim 5
Dependent Claim
34 words
An incoming call transfer terminal according to claim 1, wherein said call-setting message generating means generates said second call-setting message by copying part of said first call-setting message to a predetermined second call-setting message.
Claim 6
Dependent Claim
64 words
An incoming call transfer terminal according to claim 1, wherein said call-setting message generating means comprises: extracting means for extracting from said first call-setting message the subscriber number, known as a calling number, of a calling party at said calling terminal; and copying means for copying said calling number extracted by said extracting means to a calling sub-address of a predetermined second call-setting message.
Claim 7
Dependent Claim
25 words
An incoming call transfer terminal according to claim 5, wherein said copying means copies said calling number to said calling sub-address in an NSAP format.
Claim 8
Dependent Claim
25 words
An incoming call transfer terminal according to claim 5, wherein said copying means copies said calling number to said calling sub-address in a user-specific format.
Claim 9
Dependent Claim
64 words
An incoming call transfer terminal according to claim 1, wherein said call-setting message generating means comprises: extracting means for extracting from said first call-setting message the subscriber number, known as a calling number, of a calling party at said calling terminal; and copying means for copying said calling number extracted by said extracting means to a called sub-address of a predetermined second call-setting message.
Claim 10
Dependent Claim
25 words
An incoming call transfer terminal according to claim 8, wherein said copying means copies said calling number to said called sub-address in an NSAP format.
Claim 11
Dependent Claim
25 words
An incoming call transfer terminal according to claim 8, wherein said copying means copies said calling number to said called sub-address in a user-specific format.
Claim 12
Dependent Claim
63 words
An incoming call transfer terminal according to claim 1, wherein said call-setting message generating means comprises: extracting means for extracting from said first call-setting message the subscriber number, known as a calling number, of a calling party at said calling terminal; and copying means for copying said calling number extracted by said extracting means to user-user information of a predetermined second call-setting message.
