Method of extension
of number capacity of telephone network
INVENTION PROFILE
Background of the invention. We offer to all interested companies the Russian patented invention "Method of
extension of number capacity of telephone network". The invention relates to
the communication technology, in particular, to telephone networks with channel
switching, i.e. to public service networks, mobile, local (for example, office
or enterprise and other) networks. Using different technically realizable
solutions, this method allows creating commercially attractive for users of
telephone networks shortcut telephone numbers, which could be used by
advertising and image reasons.
Industrial prospective of
the invention. There are approximately 140 million telephone numbers
in Russia now. 40 million numbers from this amount are the numbers of wired
telephone networks and 100 million numbers are wireless (mobile) ones. The
invention allows extending capacity of wired and wireless telephone networks by
10 % i.e. by 14 million of telephone numbers due to creation of shortcut
telephone numbers. Approximately 5 million of 14 million of shortcut numbers
will be highly demanded by users of telephone networks by advertising and image
reasons at approximate price of USD 200 for one shortcut telephone number. So,
Russian market volume of shortcut telephone numbers in demand could be
approximately USD 1 billion, and not less than USD 250 million could be spend
by telephone networks operators on acquisition of special equipment, which
allows to telephone networks to create shortcut telephone numbers.
Attractiveness of the
invention to telephone networks operators consists in
fact that acquiring special equipment, allowing using shortcut telephone numbers, they will be able to make additional profit by sale
of shortcut telephone numbers to users of telephone networks. Attractiveness of
the invention to manufacturers of equipment for telephone networks consists in
the fact that they could make additional profit by production and sale of
special equipment, allowing using shortcut numbers, to telephone networks
operators. Furthermore, the invention is of commercial interest for
manufacturer of equipment for telephone networks by the following reason: in
Russia only method of extension of number capacity of telephone network by use
of shortcut telephone numbers is protected by patent, but nowhere in the world
is the invention or industrial sample, which allows to realize this method
protected by patent. It means that a company, which will patent a device for
realization of this method, will be able to sell its equipment for telephone
networks, allowing using shortcut numbers, exclusively around the world.
The global volume of the market of
shortcut telephone numbers could be USD 15-20 billion approximately, and
approximately USD 5 billion of them could be spent by telephone networks
operators on acquisition of special equipment allowing creating shortcut
telephone numbers.
Legal protection of the invention. The Russian application for invention No 2005140979 "Method of extension
of number capacity of telephone network" was submitted in December 2005.
The Russian Patent Office (Rospatent) has issued the Russian patent on the
invention No 2325777. The patent
application has been published September 27, 2007. The patent holders did not
submit applications for invention in any other countries. All rights on the
invention belong to two persons.
Offer. We'll consider licensing or outright sale of the invention. More detailed
information about the invention is at request.

according to the Russian patent on the invention No 2325777
The invention relates to the
communication technology, in particular, to telephone networks with channel
switching, i.e. to telephone public service networks, mobile, local (for
example, office or enterprise and other) networks.
It is known that all (without
exception) telephone networks work on the basis of identification of a
telephone set according to its number, which is unique for concrete network.
The quantity of digits in telephone number within a concrete network is equal
and consists for Moscow and Saint Petersburg (cities of the Russian Federation)
of 7 digits. For smaller towns consists of 6 or 5 digits, etc., with
correspondingly limited number capacity of 10 million, 1 million, 100 thousand,
etc. numbers.
Number capacity is the critical
parameter of a network, limiting possibility of extension of network. Deficit
of number capacity is inevitable in any developing network.
Known palliative measures of extension
of number capacity by addition of extra code (usually 2 to 4 digits) are not
popular due to inconvenience of use.
The closest to the invention solution
is the "short telephone number" (STN) solution, such as well-known
01, 02, 03, 09, 009 etc. numbers. But STN reduces number capacity, excluding
numbers of standard length, which begin with STN digits.
Technical result of presented invention
is the extension of number capacity of telephone networks above their nominal
capacities of 10 million, 1 million, 100 thousand etc. numbers with 7, 6, 5
etc. digits by 10 to 11 %.
The invention is realized without
significant rearrangement of equipment, mainly by program features and
introduction of additions to dialing discipline, and significantly more by
installation of correspondent gateways between main and additional networks (as
described below).
Extension is achieved by use of
N/10+N/100+N/1000... telephone numbers with quantity
of digits in telephone number N-1, N-2, N-3 ... accordingly (6-, 5-, 4- digits
for 7 digit telephone network), i. e. shortcut
telephone numbers (SCTN). Calling on such telephone numbers is executed by
simple dialing of such numbers. When telephone station detects absence of
continuation of dialing up to the nominal number of digits, after established
time of waiting of next digit (timeout), it readdress a call to a port,
corresponding to dialed SCTN.
If telephone station and calling
telephone set have possibility to dial terminal symbol (usually "#"),
this symbol is used as signal of timeout excess and jump to dialing of SCTN
without loss of time on waiting of timeout expiration.
In order to send to calling telephone
information about jumping on SCTN after interruption of entry of next digits of
called number, telephone station can admix into the line special tone signal,
which may be different for different lengths of SCTN, including tone signal in
form of voice prompt message.
A tone of call also could be different
for SCTN's of different length, which will inform a called telephone user about
SCTN call.
The separate problem is coupling of
telephone networks, using the described method of creation and use of SCTN,
with other networks, for example long distance and international networks. This
problem is solved by use of the same algorithm "no next digits within timeout
interval" on input of internetwork gateway. The only condition of
realization of such method is the arrival on gateway input of dialing digits
according to their transmission (not waiting for completion of determined
length of dialing) beginning from some minimal dialing, usually identifying
receiving station (for example, in Moscow it is the first 3 digits of number).
The additional positive effect of
implementation of SCTN is the possibility to provide SCTN of different length
with simplified mnemonic indicators to public and state services, Internet
providers for placement of modem pools, as well as commercial organizations,
interested in short telephone numbers, at market prices, which could be much
higher than standard ones due to their attractiveness, for example, for
advertising.
This method is realized particularly
simple in well computerized mobile telephone networks, where implementation of
the method reduces to extremely small modification of software for control
equipment.
Such SCTN could serve as gateways for
connection of additional networks. Additional networks could have length of
final number equal to standard length, but with pause between SCTN and number
in additional network.

INFORMATION
Beside wide known solutions with STN, there are no analogues to described invention.
