`
`BACKGROUND
`
`1. Field of the Invention
`The present invention is directed to serVice providers, tele-
`phony comptmies,inessaging‘servicc companiesmotilication
`service companies or services, database management compa-
`nies, all for private or public use. Specifically, the Dynamic
`Voil'
`(Voice over intemet protocol) location system is
`designed to provi‘deVoIP location informatiott to a server or
`multiple servers in order to enable (a) reliable data exchange
`from such server‘or servers to any device connected to the
`internet andlor (b) communication between any different
`devices connected to the internet to atleast one of the system
`servers, provided that any such devices are subscribed to the
`Dynamic VolP location system server service.
`2. Background of the Invention
`_
`Curreittsystems and methods foridentil'ylng the VoIP loca-
`tionof ti device user {be it a fixed or wireless device) con-
`nected to the inter-not to which to send data to is commonly
`done by means of the device user, at the time it requires
`certain data. to then'access a'so called URI (uniform resource
`identifier) consistingofa URL (uniform resource locator) and
`a URN (unifornt_resource name) and receive a reply to its
`“return path“ with the data it required. This ‘retum path‘ is
`what we refer to in this invention as the user‘s deviceNoIP
`lUcnlion.
`This cotnmonly used way of receiving data on demand
`when the user requires it and extracts it itself through the
`internet [VbIR is cumbersome and inflexible as it does not
`allow receipt ofthe latest, most up-to-date data orinforrnation
`as and when it becomes available as thettser may simply not
`know that data he requires is available’to him.
`More recently systems known as “Push Notification Sys-
`tem'“-have addressed this as a potential solution, howeverthey
`do not resolve the reliability aspects in terms of ensuring the
`return'patit (ife. the user‘s dcvi cc VolP location) is accurate at
`all times.
`In particular when devices connected to the internet, even
`ifsubscribed to an existing “Push Notification System“, have
`the following properties:
`a.,—for example in the case ofa fixed device, it may recon-
`nect to different VoIP (intentet) access points available to it
`flibr example, it may. disconnect from one WiFi router to
`connect to another different WiFi router)
`b.-for example, in the case of a wireless device such as a
`mobile pltone,itmay been the tnove and thus change in the
`mobile network’s "Location Area“ (LC). Ilowever, even
`within the same “Location Area" mobile networks may have
`a segmentation of several different cells. The wireless device
`VolP “Routing Area“ (RA) may therefore be difl'erent
`depending on which call it’s connected to within a certain
`"Location Area" (LA). This complexity in mobilenctworks,
`where mobile devices interact with the mobile network,
`depending on which state the mobile device is in, ensures the
`mobile network at all times updates the “Routing Area“ of
`each mobile device cotutected to it. For example when the

`mobile detrice changes cell, the mobile network updates the
`mobile device “Routing,Atea". When it changes “Location
`Area", the mobile device establishes a new connection and
`the mobile network records the new location or "Routing
`Area" of such a mobile device.
`Even the 'most recent systems, such as those known as
`1‘Push Notification" systems, do not have access to mobile
`operator‘s mobile devicesVoIP “Ru uting Area", whi eh would
`provide the reliable information needed to extract the return
`path or “VolP location" described herein. This remains a
`major'lechnieal issue still not resolved by the prior art-sys-
`tenissA key aspect inherent to the complexity of VoIP net-
`works all interconnected to each other,is that firewalls further
`complicate and reduce the reliability of most solutions.
`Another aspect thatis not resolved in both fixed and wireless
`devices, and is most critical in wireless devices, is the power
`consumption used when having to access very often specific
`URLs to see if any more updated or required information is
`available to the fixed or wireless device users, only to find out
`{more ofien than not} that the access, with the corresponding
`data use and power consumption, was unnecessary.
`Attempts have been made by companies previding'auto-
`matic Push Notifications to use databases liar those devices
`subscribed 'to their system. This in itself”does not providen
`solution to the issues described before; in particular they do
`not resolve the near real time “Wit-“i router“ or mobile net-~
`work“Routing Area“ changes (retum path—VoIP location)
`nor the minimizing of power consumption.
`SUMMARY OF THE INVENTION
`
`The present invention is designed to overcome the short-
`comings of the prior art and to provide an automated way’of
`identifying and reporting“ those Vol? return paths or “V’oIP
`location" addresses to a database for subsequent use by all
`kinds ot'difl'erent applications, with access to such database
`(s) for all those device users connected to the internal (Vol?)
`and subscribed to the Dynamic VollJ location system
`dcscribedherein. Moreover the present invention addresses in
`particular the need for power consumption reduction, in par-
`ticular for wireless devices usingthisinvention, whilst main-
`taining, the reliability of the near real-time updating of the
`VoIP return paths or "Volt" location“ addresses of each
`mobile device user connected to the internet (VoIPJ and sub-
`scribed to this Dynamic VoIP location system described
`herein.
`_
`The present invention is preferably a sentice offered by
`Voll’ sewice providers, VoIl’ telephony companies, VoIP
`messaging service companies, VoiP notification service com-
`patiies,VoIP database management companiesor VoIP Data
`Content Providers.
`As a matter ofillustration ofthe present invention, consider
`the useby'aVoIP serviceprovidcr withregistered users using
`mobile phones, who in the pri orart would have an application
`of a VoIP service provider running permanently on these
`mobile phones, each connecting to a SIP server at an interval
`of several, seconds. This previous system or method, whilst
`ensuring the return path is known to the SIP server, which can
`then send incoming calls signallingas and when theyhappcn,
`becomes unpractical inits daily use at it drains the battery of
`the mobiledevice.
`
`Other systems knowa in the prior art make use of so called
`Push Notification systems, whereby the mobile device appli-
`cationis also subscribed to the push notification system of a
`3‘“1lrparty. ditl‘erenttlten theVolP service provider. In this latter
`system, the mobile phone has the Vol? service provider appli-
`cation switched ofi; waiting for the push notification system

`to notify the mobile device with an incoming request, be it an
`incoming message or an incoming call..'lhis previous system
`or method, whilst ensuring the battery use of the mobile
`device is minimal, do es not ensure a reliable return path. That
`is because the mobile device may have changed Wilii router
`or mo bile networkVolP "Routing Area“. On many occasions,
`it would not receive the push notification when on the move,
`and as such this approach becomes impractical fordaily use
`for mobile devices.
`The present invention resolves both key technical aspects
`of theprior art,L namely a reliable return path (ie. VolP Idea:
`tion] whilst ensuring minimal required power consumption.
`This is achieved by doing things difl‘erently from the prior art.
`Namely, this invention does not rely on the.mobile network
`VoIP “Routing Area" as it does not have access to it. Instead
`however, it relieson the mobile device downlondable soft-
`ware module, which at any change ofVoIP access method or
`name, attthenticatesand connects to the DynamicVolP loca-
`tion system to which the mobile device is subscribed to and
`described herein. The combination of this software module
`‘(downloadable to each mobile devich together with the
`dynamic retunthpath (Voll’ location} extraction atihe server of
`each mobile device connected to the server to which it‘s
`subscribed to, jointly form the“ Dynamic VolP location sys-
`tem. As the mobile software module additionally checks if
`any other application is running on the mobile device other
`then itself, including in standby mode, 'it will close all other
`applications (such as for example the application of the pre-
`vious mentioned SIP service provider) AND will switch the
`Vol? access method of the mobile phone to the smallest
`bandwidth available to such mobile phone, for example
`switching from 3.0leMTS!WCDMA to GPRS.
`This last action by the software module, reduces the power
`consumption of the mobile phone to the leviest' possible,
`whilst still ensuring Voll’ connection by the mobile phone.
`The mobile network's “RoutingArca” still ensures including
`border areas in coverage, due to the factthat small bandwidth
`fie. GPRS) is more reliable then high bandwidth (in. 30).
`This ensures the highest possible reliability also for the
`Dynamic VolP location system of this invention.
`As stated before. the software. module (as a part of the
`DynamicVoIP location system) is downloadable by.a mobile
`device which will then connect and authenticate to the server
`ofthe Dynamic VoIP lo cation system at certaintime intervals,
`but
`in particular at. each change of wireless connection
`method or name. For example, any time the software module
`detects a change from‘BG to GPRS or from GPRS to WiFi or
`from Willi router name c to another WiFi mater name of from
`no wireless to a wireless connection no GPRS to GPRS or
`from WiFi loss to GPRS, then the software module will con-
`nect at that specific time and authenticate to the server. When
`no change is detected for a certain time period then at regular
`longer time intervals to so to power consumption the software
`module will optionally also connect to the server to ensure
`that when a mobile changes cell in a mobile network that this
`results in a connection from the software module to the server.
`In this way the server will be able to keep the VoIP return path
`or “VolllI Location" of each tnobilc device registered to the
`DynamicVolP location system up to date.
`An object ofthe present invention is to reduce the time and
`effort. but more importantly the probability of error, to syn-
`chroni 2e a databa sefrom a private individual orha siness with
`the database of?“ pany,-perfonned in a fully automated and
`dynamic manner by the 3" party, with express consent of
`such private individual or business.
`Another object of' the present invention is to provide a'
`system that maintains the “Vol? location" or return path of.

`each registered Vol? device user updated in a database (for
`use by applications to communicate with each such user at a
`future time, as described herein) by reducing the power con-
`sumption ofsuch registered Vol}? user devices to a minimum.
`Rte-capping, the invention in a first aspect is a system for
`detecting or determining any given "Vol? location“ of any
`“VolP/cna bled device registered to the system“ by extracting
`any such device’s “YoIP address or return path” and storing it
`and updating it in one or more accessible databases, in which:
`(a) the system is adapted to receive Vol? communications
`from multiple Vo'lP enabled devices; (h) the system enables
`access to information in one ormore databases; (c) the system
`is capable ofextructing and reporting dynamically the “VoIP

`system.
`the server then authenticates ifit‘s a registeredVolP device
`user and extracts the “Vol? address or rctum path" and
`stores this data into the registered Vol? enable device
`user account as the “Vol? location" and the server can at
`any time send data many Specific registered VoIP device

`DETAILED DESCRIPTION OF 'I'HEJNVENTION
`
`Referring to FIGS. 1 and 2, a Dynamic Vol? location
`system Which could be a private or commercial server 100
`{VoIPlpcaticn server), in any locationintlte worldwliiclt uses
`intern'et services, and which includes one or more databases
`(Vol? location datab use} and an external internet access c2 to
`the system 100. Additional external access means to the sys-
`tem can also be present. Additional external databases 10].
`(VoIP lo cation databa so) may be accessible to the systemjlflt].
`The system server 1004 could [test the ‘soflwarc ntodulc‘
`[VcIP location software module ‘sin’J downloadable into a
`Wireless device; for example the ‘soitware module‘ as shown
`in FIGS. 1 and 2 in each wireless device WD_x1 andWD_yl
`and WD_wn and WD_:m and so forth in FIG. 1.
`To use the l‘Dynami‘c VoIP location system" service. the
`device users must connect to the Vol? location server and
`subscribe to the service. in sortie very specific cases, where
`the informaticnofa sp ecific database aecessibleto the system
`consists explicitiy and only ofpubhc information without any
`.Iegal restriction on disclosme of any form front any third
`party whatsoever. only- in this last case potentially no sub-
`scription would be required if so decided by such 3’“ party.
`The Dynamic VoIP location system consisting of at least
`”one VolP location server '100’ and at least two or more
`devices that incorporate a ‘sm’Woll‘ location software mod-
`ule). The Voll’ location server preferably keeps a record ofthc
`subscribers (with their express consent) in a database 101,
`preferably resident within the same server ] titla 11d stores their
`user identification and originating Vo‘lP address or VoIP
`return pathtreferred to herein as the user’s “VoIP location”)
`to reply to.
`In the example shown in FIGJ, it is assumed that wireless
`devices are subscribed the Dynamic VolP location system
`(100) and haven YoIP location software mo dule {sm) embed-
`ded in each user's wireless device. All wireless devices with
`a built in 'sm‘ authenticate and communicate with serverl 0!]
`even when the Wireless device is in standby mode. The ‘sm’
`communicates with Server 1 [It] after wireless device power-
`up and each time the wireless device changes Voll’ access
`name (for example when changing, between any of the fol-
`lowing 36,. GPRS, WiFi or between any ofthe previous and a
`new different to the previous XVIFi router name and when
`changing between mobile cells. Tito ‘sm’ will force the wire-
`less device to close any such other applications differentfrom

`the ‘sm’ itself that requiresVolP connection and additionally
`will force the wireless device to switch to the lowest available
`bandwidth Vol? access means, for example switch from
`3G!WCDMA to GPRS, as shown in FIG. 2.
`'llte VolP location server 100 will, each time a wireless
`device {WD_X1, WD_Zn, etc.) with a built in \folP location
`software module ‘sm.’ subscribed to the Dynamic VoIP loca»
`tion system connects with the server store the return reaponse
`path referred to in this invention as each wirelLss device
`usersVoIP Location and wldchfor example will correspond
`in the event oi'a wireless device connect through GPRS with
`its 'unique PSPDN (packet switched public data network)
`address at such time.
`As amatter ol'illustration ot‘the workings ofthe Dynamic
`Voll’ location system, wherein SG enabled wireless device
`WILyl wishes to call 36 enabled wireless device WD_xI,
`where both devices incorporate a SIP software application
`that enables VolP conversations and incorporate also this
`inventiott’s Vbll" location software module ‘sm‘. Both
`WD_xl and WD_yl latest VolP location (Volt? return pathor
`also known in the industry as PSPDN (packetswitched public
`data network] address is stored inV'oIP Location serverlfltt or
`in external database 101 accessible to the server '100 and
`updated by the wireless devices as described herein before.
`The ‘sm‘ in both wireless devices have switched the wireless
`devices to the least power consuming GPRS instead of the
`higher power’consutning 3G.
`As illustrated in FIG. 2 Wireless device userWDJ‘l starts
`opening its SIP application (wireless device exits standby
`state). whereby ‘sm‘ switches WD_y.1’ from GPRS to 36
`{highest available VoIP bandwidth) and the user initiates a
`SIP to WD_xl who is in standby tnode throughVolP connec-
`tions c3,-c6 and c214. The VolP SIP server infonnsYolP loca—
`tion server 100 through connection c15 of a call request
`originated by WD_yl and destined for WDJ]. The VoIP
`location server 100 will reply with the latest Vol? location
`address available111 its database DrWDJtI through connec-
`tions c2 and ’c1-c5 and send data with instructions for WD_x1
`Voll‘ locationsoitwarc module‘ sm‘ to switch from GI’RS to
`36 {highest available VolP bandwidth)and activate‘the cor-
`responding SIP application to allow'it to receive the'1ncoming
`call ringing signalling, or alternatively to notify the user of
`WD_x1 with a notification of an incoming call such that the
`user can accept or reject it In the event of acceptance of the
`incoming notification the corresponding action will be auto-
`matically perforated by the' sm’, for example activate the
`corresponding SIP application as to accept the incoming call
`request originated by WD_yl.
`Referring to FIGS. 3 and 4, these show the tinting of
`communications between the two main parts of'the Dynamic
`VolP location system, nantely between Voll’ location sofi-
`ware module ‘sm’, referred to in FIGS. 3 and 4 us "Client
`Ping" and VoIP Locationscrver ‘100’, referred to in FIGS. 3
`and '4 as "Server Reply". it illustrates the same previous
`example of a SIP call originated by WD_yl, referred to in
`FIGS. 3 .and 4 us 'Call 1‘ and a subsequent later call also
`originated byWDJlrofertcd to as ‘CallZ‘. Both ‘Call 1‘ and
`‘Call 2‘ are destined for WD_xl, as explained herein. The
`time ‘l’t“rel'ers to the time between two consecutive commu-
`nicationsjVolP location updates) betweenWDJI and server
`100 and the corresponding VoiP locationupdate'in the data-
`base 100 or 101 corresponding to WD__.x1 The timing ‘Rets
`the time the sofiwa‘re module ms’ allows the server 100 to
`send a reply that WD_x1 would deem acceptable as valid.
`This time ‘Rt’ is defined by the wireless device‘s ‘sm‘ as ‘Rt‘
`being bigger then ‘Pl’ whcncotnmunicating with scrvcr100.
`It is important to note, that the time ‘Pt’ may vary between

`consecutive ‘Pt‘s’ and the ‘sm‘ also dynamically adapts the
`allowed ‘Rt‘ by server 1th in compliance with previous con-
`dition of ‘Rt‘>‘Pt‘ . It is also important to note that the server
`100 does not necessarily reply to ‘sm‘ communications for
`VolP Location updates, but simply extracts and stores ’the
`VoIP Location address in the corresponding database user
`data and only replies to the corresponding wireless device‘s
`‘sm‘ exactly at the time when the server 100 has data for a
`specific subscribed u5er’s ‘srn‘ (be it anotiiicution of some
`sort or a message or an incoming call and so forth). This last
`is in fact possibleto be instant-note. at the tilne the server 1 00
`has data to be sent to a specific device's ‘sm‘ because of the
`condition o
