Abstract
Abstract The invention concerns a method of establishing a data packet communication session between a calling terminal arrangement (T1) and a called terminal arrangement (T2), the terminal arrangements terminating both a data packet network (IP) and a telephone network (PSTN), wherein a source exchange (EX1) of the telephone network (PSTN) receives at its interface to the calling terminal arrangement (T1) a first address information with the telephone number of the called terminal arrangement (T2) and the data packet network address of the calling terminal arrangement (T1), the source exchange (EX1) transmits a second address information message (M12) to a destination exchange (EX2) over the signalling network of said telephone network (PSTN) with the data packet network address of the calling terminal arrangement (T1), the destination exchange (EX2) transmits a third address information message (M13) to the called terminal arrangement (T2) with the data packet network address of the calling terminal arrangement (T1) and the called terminal arrangement transmits the data packet network address of the called terminal arrangement (T2) to the calling terminal arrangement (T1) over the data packet network (IP) or the telephone network (PSTN), as well as an exchange (EX1, EX2) therefore. <IMAGE>

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
196 words
A method of establishing a data packet communication
session between a calling terminal arrangement (T1) and
a called terminal arrangement (T2), the terminal
arrangements terminating both a data packet network
(IP) and a telephone network (PSTN), characterised by the following steps: a source exchange (EX1) of the telephone network
(PSTN) receiving at its interface to the calling
terminal arrangement (T1) a first address information
message (M11), the address information comprising the
telephone number of the called terminal arrangement
(T2) and the data packet network address of the
calling terminal arrangement (T1), the source exchange (EX1) transmitting a second
address information message (M12) to a destination
exchange (EX2) over the signalling network of said
telephone network (PSTN), the address information
comprising the data packet network address of the
calling terminal arrangement (T1), the destination exchange (EX2) transmitting a third
address information message (M13) to the called
terminal arrangement (T2), the address information
comprising the data packet network address of the
calling terminal arrangement (T1) and transmitting the data packet network address of the
called terminal arrangement (T2) to the calling
terminal arrangement (T1) over one of said networks
(IP, PSTN), the terminal arrangements (T1, T2) are
terminating.
Claim 2
Dependent Claim
131 words
A method according to Claim 1, wherein the data packet
network address transmission of the called terminal
arrangement (T2) to the calling terminal arrangement
(T1) is transmitted over the telephone network (PSTN)
performing the following steps: the destination exchange (EX2) receiving at its
interface to the called terminal arrangement (T2) a
fourth address information message (M21), the address
information comprising the data packet network
address of the called terminal arrangement (T2), the destination exchange (EX2) transmitting said
address information in a fifth address message (M22)
to the source exchange (EX1) over the signalling
network of said telephone network (PSTN) and the source exchange (EX1) transmitting a sixth
address information message to the calling terminal
arrangement (T1), the address information comprising
the data packet network address of the called
terminal arrangement (T2).
Claim 3
Dependent Claim
56 words
A method according to Claim 2, wherein for transmitting
the address information between the source exchange
(EX1) and the destination exchange (EX2) over the
signalling network, the data packet addresses and the
telephone numbers are embedded into an application
layer message, said message being transported by means
of a transport layer protocol in the connectionless
mode.
Claim 4
Dependent Claim
62 words
A method according to Claim 3, wherein the signalling
network is based on the signalling system number seven
defined by the International Telecommunication Union,
wherein the application layer message is a Transaction
Capabilities Application Part message of the signalling
system number seven, and said message being transported
by means of the Signalling Connection Control Part
protocol of the signalling system number seven.
Claim 5
Dependent Claim
31 words
A method according to Claim 1, wherein the address
information of the second and the third address
information messages (M12, M13) comprise the telephone
number of the called terminal arrangement (T2).
Claim 6
Dependent Claim
34 words
A method according to Claim 1, wherein the address
information of the fourth the fifth and the sixth
address information messages (M21, M22, M23) comprise
the telephone number of the calling terminal
arrangement (T1).
Claim 7
Dependent Claim
38 words
A method according to Claim 2, wherein for transmitting
the address information between the terminal

signalling interface.
Claim 8
Dependent Claim
51 words
A method according to Claim 2, wherein for transmitting

sending, the connection is released.
Claim 9
Dependent Claim
