Service setting system, a service setting method and a relay apparatus
First Claim
1. A service setting system comprising:
- at least more than one service control apparatus for controlling whether setting of service requested for communication should be performed;
an source communication terminal for transmitting a packet of service request, wherein the packet of service request stores a parameter of a service requested for said communication, an address of a communicating apparatus of a said service target, a current source address which is an address of origin and a current destination address which is an address of designation both for transferring and receiving own packets; and
a relay apparatus for judging whether said packet of service request should be transmitted to said service control apparatus which controls own said setting of service based on said current source address in said packet of service request.

Abstract
The present invention is aiming at a service setting system, a service setting method and a relay apparatus which does not require implementation of a communication protocol to inquire whether a service between a relay apparatus and service control apparatus should be provided, and which cut down a delay until service provision.
A relay apparatus 3, that received a service request signaling packet transmitted from communication terminal 1, transmits this service request signaling packet to a service control apparatus 6 in case this service request signaling packet is not transmitted from a service control apparatus 6 which controls own setting and a service control apparatus 6, that received a service request signaling packet, controls setting of each relay apparatus.

1. A service setting system comprising:
-
at least more than one service control apparatus for controlling whether setting of service requested for communication should be performed;
an source communication terminal for transmitting a packet of service request, wherein the packet of service request stores a parameter of a service requested for said communication, an address of a communicating apparatus of a said service target, a current source address which is an address of origin and a current destination address which is an address of designation both for transferring and receiving own packets; and
a relay apparatus for judging whether said packet of service request should be transmitted to said service control apparatus which controls own said setting of service based on said current source address in said packet of service request. - View Dependent Claims (2, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

3. The service setting system comprising:
-
at least more than one service control apparatus for controlling whether setting of service requested for communication should be performed;
a proxy server for transmitting a packet of service request, wherein the packet of service request stores a parameter of a service requested for said communication, an address of a communicating apparatus of a said service target, a current source address which is an address of origin, and a current destination address which is an address of designation both for transferring and receiving own packets; and
a relay apparatus for judging whether said packet of service request should be transmitted to said service control apparatus which controls own said setting of service based on said current source address in said packet of service request.

34. A service setting method comprising:
-
transmitting a packet of service request, storing a parameter of service requested to communication, a current source address which is an address of origin between apparatuses which currently perform transmission and reception of data in said communication, and a current destination address which is an address of a destination apparatus between apparatuses which currently perform transmission and reception of data in said communication;
controlling whether a service requested from said communication is performed;
rewriting said current source address in said packet of service request on receiving said packet of service request; and
judging whether a packet of service request, in which said current source address is rewritten, is transmitted to an apparatus controlling setting of said service based on said current source address before rewriting in said packet of service request.

35. A relay apparatus for receiving a packet of service request storing
a parameter of service requested to communication, a current source address which is an address of an source apparatus between apparatuses which currently perform transmission and reception of data in said communication, and a current destination address which is an address of an destination apparatus between apparatuses which currently perform transmission and reception of data in said communication; -
relays data necessary for said communication, rewrites an origin of said existing transmission of a message address in said packet of service request to an own address on receiving said packet of service request, rewrites said current destination address in said packet of service request to an address of an destination apparatus of the next packet of service request, and judges whether a packet of service request, in which an origin of said current transmission of a message address and said current destination address is rewritten, should be transmitted to a service control apparatus, which controls a setting of service requested for own said communication, based on said current source address before rewriting in said packet of service request.

36. A relay apparatus for receiving a packet of path search, wherein:
-
said packet of path search stores p1 a current source address, which is an address of origin between apparatuses that currently perform transmission and reception of data in communication, a current destination address which is an address of designation between apparatuses which currently perform transmission and reception of data in said communication, and a last relay apparatus destination address which is a last relay apparatus destination address which is an address of a destination apparatus of a packet of service request that transmits a communication terminal requires service for said communication;
rewrites said last relay apparatus destination address to an address of service control apparatus controlling own said setting in case said current source address before rewriting is not an address of an apparatus, whose setting is controlled by a service control apparatus which controls setting of service requested for own said communication, on receiving said packet of path search, and transmits said packet of path search.
