Background 1. Field of the invention

The present invention is directed to the field of Data communications using a mobile device. Plus specifically, the invention relates to the technique of redirecting data to a mobile device that has a wireless interface able to communicate through a plurality of routes or communication paths

2. Description of the related technique

Systems and methods are known for copying or reproduce data from a host or host system, such as a desktop computer system or a server network, for a mobile user device. These systems employ typically "synchronization" schemes in which data of the user are saved (or stored) on the host system for an indefinite period of time and then mass transmitted in response to a request by the Username. In order to reproduce the stored data, the user typically place your mobile device on a stand or hanger interface that is electrically connected to the host system, and then execute an order on either the mobile device,  either on the host system, in order to start copying or reproduction. These known techniques employ a paradigm of "extraction" that requires the user to adopt stages positive or affirmative to obtain data from the host system. The only moment in time when the host system and the mobile device are truly "synchronized" is the moment of reproduction. A few minutes or even more seconds late, a new data item may arrive at the host system (or to the mobile device), but this new data element will be synchronized only in the next instance of the order of playback that is running.

Systems are also known for redirect phone calls or add phone numbers to a certain phone number These systems require the user manually reconfigure an aggregation telephone switch using a plurality of phone numbers, so that Calls are routed to a new location. They are also known systems that track the number of rings on a given phone number and redirect the call to another number after a set number of ring signals no answer In this type of system, they are presented, in occasions, to users special voice messages that ask them Wait until the call is rerouted. Often the caller will hang up in response to that message, instead of await additional ring signals at another number of phone.

Another known type of system to communicate data to mobile devices is the original warning based system by portable locator device or "search". This type of system uses a small device located on the belt, that can visually present a phone number to call in case of emergencies These systems were typically offered as third-party services that were far from the facilities of a company, and were not related to the communication of the company's private data, in a secure way, to mobile users. Advanced versions of these systems Notice by portable locator device are able to transmit an alphanumeric message or even a simple message from email limited to around 170 characters or less. To use these systems, the user must accept a second email address, a second phone number or a contact number, and sometimes a third number called Personal Identification Number (PIN - "Personal Identification Number ") to communicate with the portable warning device. These systems also do not provide security and privacy. robust, which constitutes a major concern to the time to transmit sensitive business data outside the Company network

US 5,210,785, for example, describes a mobile device that has Transceivers, or transceivers, long range and short range, as well as a control unit for Select long or short range communication. He short range transceiver is intended to communication with a wireless telephone base station (fixed unit). Short range communication is selected when the mobile device is within the reach of the Wireless or wireless base station. The control unit of the device detects signal reception states in the long-range and short-range transceivers of the device, and select the communication based on these signs.

Detailed description

Referring then to the Figures, Figure 1 is a system diagram showing elements  of data 95 when redirected from a host or host 120 operating on a desktop computer of a user, to a mobile device 100 through a plurality of routes or paths of communication. In addition to the mobile device 100 and host system 120, the system includes one or more RF-capable interface stands or hangers 110 [radio frequency], a wide area network 135, an application of redirection 130, a wireless gateway 145 and a wireless network 150

Figure 1 shows two communication paths possible to redirect data items to the mobile device 100. In a first way, redirection application 130 will is in communication with the mobile device 100 through a long range wireless network comprising an area network Extensive 135, a wireless gateway 145 and a wireless network 150. The long-range wireless communications path can be, for example, the Mobitex Radio Network ("Mobitex"), the Network of Radio DataTAC ("DataTAC"), the Multiple Access network by Code Division (CDMA - "Code Division Multiple Access"), the Mobile Special Group or the Global Communications System Mobile (GSM - "Global System for Mobile Communications"), and the General Packet Radio Service (GPRS - "General Packet Radio Service "), or future third generation networks (3G) like the UMTS [Universal System for Mobile Telecommunications - "Universal Mobile Telecommunications System"], EDGE [Rates of Enhanced Data for GSM Evolution - "Enhanced Data Rates for GSM Evolution "] and W-CDMA (CDMA broadband - "Wideband-CDMA").

In a second way, the application of redirect 130 is in communication with the device 100 mobile through a short range wireless network that it comprises an interface 115 and an interface hanger 110, which is preferably equipped with a Transceiver, or transceiver, wireless RF short range. The short range wireless interface can be, for example, a Bluetooth type interface or any other Type of short-range RF interface. The interface hanger 110 You can communicate with the mobile device in two ways. In First, physically and electrically connecting the device mobile 100 to hanger 110. Second, communicating signals wireless short range between wireless RF transceiver hanger 110 and a short wireless transceiver range located on mobile device 100.

Figure 2 is a system diagram showing data elements 95 when redirected from a host system 120 operating on a network server 225, to a plurality of mobile devices 100 through a plurality of communication paths. The host system can be a desktop computer system, a network server, an Internet Service Provider (ISP), a telephone switch, a router or mail routing device or a storage area , an information database, or some other type of primary data center. The 120/225 host system functions as a storage / redirection facility to host the mobile user data and to redirect the data to the user's mobile device. The host system 120/225 is preferably located behind a company firewall 155, which acts as a privacy barrier to protect sensitive company information. The host system can also be directly connected to redirection software 130, so that both act as a single program. In this embodiment, it is said that the host system 120 is "wirelessly trained" by redirection software 130. This cooperative relationship between the redirection software and the messaging system can be used to wirelessly enable any messaging system. The messaging systems that are commonly used include the Microsoft "TM" email system, the IBM TM Lotus Notes message system and the IMAP4 standard Internet message system.

Figure 2 is similar to Figure 1, a exception that the network server implementation allows a  single redirection application 130 serving a plurality of users when receiving data elements from a plurality of sources and by redirecting then those data elements to a plurality of users. Although it is shown in Figures 1 and 2 a single redirection application 130, the system can be expanded for use with multiple redirection applications 130.

Redirection application 130 operates, preferably, in host system 120, although it may function in some other system and be in communication with the host system 120 through a network connection. This one receives, process or process, store, filter and redirect data elements from host system 120 to mobile device 100. The redirect device 130 also works to determine the best route or path of communication through which they should Data elements be redirected. This determination is based in information collected and stored in the device redirection 130 (or that is accessible by the application of redirection), which identifies the approximate physical position of the Mobile device user. The redirection program 130 is a event-activated program that operates on host system 120,  which upon detecting that a particular event has occurred user-defined, redirects data elements selected by the user from the host system to 100 mobile device of the user. Redirection Program 130 It also acts as an interface for components that can detect physical location of the user and perform a road search less congested, the shortest path or the best path propagation to redirect user information. The information can comprise data messages, elements of telephony, video elements or any digital information or analog that can be supplied to a host system 120 of Username. For the sake of clarity, the expression "elements of data "shall refer to all forms of information that are due send to the user, including data, voice, video and other information digital. For reasons of brevity, the expression "system host "includes either a stand-alone desktop computer or independent, connected to a LAN [local area network - "Local Area Network "], either a fixed installation as an offer of ISP services [Internet Service Provider - "Internet Service Provider "], or a computer terminal associated with a network, connected a server and / or an Internet plug connected to the Internet or Intranet, although it is not limited by them.

For example, in the network implementation that shown in Figure 2, as a mobile user moves in physical proximity to one of the interface hangers 110 trained for RF, information is sent to the application of redirect 130 that identifies mobile device 100 and the network address of interface hanger 110. Using this information, redirect application 130 will redirect any elements of incoming or altered data, through the LAN (or other network), to interface hanger 110 and, to then to the mobile device through a communication path of RF short range. Once the mobile user moves moving away from the interface hanger 110, information is sent additional to redirect application 130 which indicates that the user is no longer in physical proximity to hanger 110 particular. The redirection device 130 will then redirect any data elements to mobile device 100 through of long-range RF communication path 135, 145, 150 until the moment the mobile user moves in close physical proximity with another interface hanger 110.

A mobile user who communicates with this system can have multiple offices from which the user can work, including a home based office or domestic, a plurality of compartmentalized offices in a plurality of office buildings, a workstation located in a distant office space, etc. As the user gets move in and out of your home office and the others offices, a communication path is established or interrupted wireless between mobile device 100 and host system 120. As the mobile user interrupts contact with space physical of your home office (and, consequently, the device mobile 100 interrupts contact with a support or hanger 110 of interface located in the home office), the program of redirect 130 starts routing data, email, voice calls, video calls, etc., as well as all others direct communications with the mobile device 100 through the long range wireless network 135, 140, 145. In another embodiment, each commercial office is constituted by "cells", denominated in this application pico-cells 110 & 605, which are shown in detail in Figure 8. As the user moves from one place to another in the office, it is, preferably, reconnected to the peak cell of short range 100 & 605 that is located closest to it, Whatever it is. In this way, voice and data can be routed within firewall 155 and the LAN space of the company to whatever office or cell in which it find a given user at that time. Advantageously, This system provides greater bandwidth, efficiency in regarding costs and fast supply of redirected information From the domestic office. As a user moves from a site to another, having meetings and mini-conferences, all your phone calls, data messages and emails will also take the shortest path to the user inside the building of the company. Only if the user abandoned physical proximity to the company building, or coverage within the building were insufficient, the wireless area network would have to be used Extensive and long range.

It should be understood that the term "office" and the expression "office environment", as used here, they can refer to any partially or closed location closed, and are not limited to the places where they are held business. The expression "office environment" implies a relationship between the user and the host system 120. In the largest part of today's companies, this relationship is defined by the installation of a 155 firewall around the LAN environment corporate, which acts as a privacy barrier for all types of information. Advantageously, the invention supports this relationship. secure created by the company's 155 firewall and allows the information is routed safely to the user without compromise the security of the company. The firewall contributes to define the relationship between an individual and their data corporate

Alternatively, it can be provided to the redirect application 130 real-time information concerning to the quality of the various communication paths towards mobile user, and this one can use this quality information in order to determine the best communication path for Redirect data items. For example, even though the user may have reached close physical proximity with one of interface hangers 110, the link between the application of redirection 130 and interface hanger 110 may have degraded in quality due to network congestion. In this situation, redirection device 130 will return to the network Long range wireless 135, 145, 150 in order to redirect information to mobile device 100. In another situation provided by way of example, the mobile user is in close physical proximity with two interface hangers 110 with RF capability, but one is less congested than the other (that is, fewer mobile users are communicating with one of the hangers than with the other). In this situation, the application redirection 130 can determine that the best path to communication until the mobile user is through the hanger of less congested interface, and will then redirect the data in correspondence.

Using the redirection program, the user can select certain data items to be redirected, such as phone calls, emails electronic, calendar events, notifications of meetings, address entries, press entries, personal reminders, etc. As new ones are added types of data elements to the system, the user can add these new types of data items to a list of personal preferences that is maintained by the device redirect 130. The user can review a list of items that could be redirected to your mobile device, and select those types of data items that the user You want them to be redirected. Once the elements of data to be redirected, the user can then configure one or more event triggers to be detected by part of the redirection program and intended to start the redirection of user data elements. These points triggers (or event triggers) defined by the user can include external events, internal events and events connected or associated to a network.

Examples of external events include: receiving a message from the mobile data communication device of the user to start redirection; receive a similar message from some external computer; detect that the user no longer knows found in the vicinity of the desktop computer by medium of short-range RF link with hanger; or any other event that is external to the host system. Events internal can be a calendar alarm, the activation of a screen saver, time, disconnection of a keyboard, a programmable timer or any other event defined by the user and that is internal to the desktop computer. The events associated with a network are user-defined messages which are transmitted to the host system from another computer connected to the host system through a network in order to Start redirection.

A redirect application provided to example mode for use with this system is described with greater detail in U.S. Patent No. 6,219,694, entitled "System and method to advance information from a system host to a mobile data communication device ", of same assignee as the present application.

The systems shown in the Figures 1-2 operate, preferably, as follows. Custom that data items 95 arrive at the desktop computer 120 (or network server 225), are processed or treated by the redirection software 130. Redirection software 130 is operating, preferably, well within the desktop system 120 or as part of network server 225. The software of redirect 130 determines the best communication path for reach a particular user associated with a data item incoming and then routes data item 95 to through the best route or path of communication. This stage of Determination can take many forms. In a preferred way, redirection software 130 maintains a base entry of data for each mobile device 100, which indicates whether the device mobile 100 is now in the vicinity of a hanger 110 interface that has a wireless RF interface, as well as the network address of that interface hanger 110. If a concrete mobile device is in the vicinity of said interface hanger 110, then the device redirect 130 treats and transmits data element 95 through from the LAN (in the example in Figure 2) or directly to the hanger 110 (in the example of Figure 1), which then transmits the data element 95 by the short range RF link to mobile device 100. Yes, however, mobile device 100 does not It is in the vicinity of any of these hangers Interface 110, then redirect application 130 routes the data element through the short range wireless network 134, 145, 150 towards the mobile device 100.

Preferably, when a user of a mobile device 100 enters within the physical proximity of a interface hanger 110 that has a short range RF link, the mobile device 100 transmits a contact message to the hanger 110. This contact by message is then processed or treated and is provided to redirect application 130 contact information indicating that mobile device 100 is is now in the physical vicinity of hanger 110 particular. Then when the mobile device 100 abandon physical closeness with the particular hanger 110, the hanger 110 detects the absence of communication from the mobile device 100 and notifies redirection application 130 that the mobile device 100 is no longer in the vicinity of the hanger 110. In this way, redirection application 130 can determine the approximate physical position of the mobile device 100

Other methods provided by way of example to determine the approximate physical position of the mobile device 100 (and, therefore, of the user) include: (1) detect the presence physics of the mobile device 100 in the physical serial hanger 110, (2) detect the activation of a screen saver program associated with the host or host desktop system, use heat sensors to determine if the user has abandoned the host system zone, (4), use a detector of visual images to determine if the user is not present, or (5) receive a direct order from the user to redirect the information in a certain way. In each of these cases, to the redirect application 130 is provided with information that this one uses to determine the best communication path for redirect data to mobile device 100.

In the case of the network server 225 of the Figure 2, there is an additional stage consisting in determining what Network workstation 220 has received data item 95. This additional stage is necessary to associate the data element 95 to a particular mobile device 100. This can be done by means of a special address, such as "A address "(" To Address ") in an email electronic, or it can be carried out using an extension phone for an incoming phone call.

In an embodiment that is described with greater detail later, the mobile device 100 may have configured with a plurality of components endowed with capacity wireless, including (1) a first component 310 for the Long storage, recovery and RF communication scope of the data, and (2) a second component 305 to Audio input / output and short range RF communication. Alternatively, a short range RF transceiver both in the first component 310 as in the second component 305. The second component 305 is preferably a removable headset which is placed in the user's ear. This second component 305 can communicate directly with the interface hanger 110 to via the short-range RF communication link, or can communicate with the first component 310, which communicates then with the interface hanger 110. The first component 310 preferably placed in a holster or holster attached to the user belt

Using this device 100 mobile multi-transceiver, if the user found in the same room as (or in close proximity physics with) one of the interface hangers 110 trained to RF, then data elements 95 are redirected from the interface hanger 110, either directly to the component of headset 305 or the first component 310. For example, the system can be configured in such a way that the information of voice, such as voice messages or real-time voice calls, are redirected directly to headset component 305, in so much that data information, such as emails electronic, files or other types of digital data, are redirected to the first component 310 worn on the belt. In this way, the information is redirected directly to the user without there being a manual intervention with the computer system of desktop 120.

As described above, the system host 120/225 is preferably located behind a enterprise firewall system that protects business data delicate of the company. The system described here works in combination with the company's security mechanisms existing (including the firewall system), when extending a secure desktop / business environment to cover wireless mobile devices This security takes place at through the exchange of a shared secret (such as a key public for encrypted or encrypted / decrypted data) between the 100 mobile device and 120/225 host system, preferably through the trained interface hanger 110 for RF. This operation effectively extends the firewall of the company around the mobile device 100, which creates a virtual private wireless network (VPWN - "virtual private wireless network ").

Figure 3 is a logical flow chart that show how a shared secret can be exchanged securely between a mobile device 100 and an application redirection 130 in the system shown in the Figures 1-2. The method begins in stage 250. In stage 252, the user configures a security password, which It is stored in combination with redirect application 130. When the user is ready to exchange the secret shared, the user places the mobile device 100 in contact Electrical and physical 254 with interface hanger 110. The user it is then urged, as indicated by reference 255, to enter a security password on the mobile device (or in a desktop system coupled to hanger 110 of Interface). If the security password is not valid, then  the method ends as indicated by reference 264. Yes, for On the contrary, the security password is valid, then, in step 258, the shared secret is exchanged and stored in redirection application 130 and inside the 100 mobile device. This shared secret can then be used by redirection device 130 to encrypt or encrypt the data before being redirected, and also by the 100 mobile device to decrypt the encrypted data. Similarly, the shared secret can be used to encrypt the response information on the mobile device 100 and for decrypt the encrypted response information on the device redirection 130. In step 260, the method determines, to then, if the particular mobile device 100 has two wireless components, such as the device mentioned above and described in greater detail below. Yes The mobile device 100 does not have two wireless components, then the method ends as indicated by reference 264. If, on the contrary, the mobile device 100 includes at least two wireless components, then, in step 262, the same (or some other) shared secret is exchanged, then between the first component 310 of the mobile device 100 and the second component 305 of the mobile device 100. In this way, a secure end-to-end connection can be established between redirection application 130 and mobile device 100, which includes a second 305 wireless mobile device component 100

Figure 4 is a perspective view from below a mobile device 100 provided by way of example and that it has a first wireless component 310, capable of being worn on the user's belt, and a second component wireless 305, intended to be inserted in the user's ear. The Figure 5 is another perspective view from below the device mobile 100 provided by way of example and shown in the Figure 4, in which the second wireless component has been removed 305 of the first wireless component 310. Figure 6 provides a closer look at the mode like the headset or hearing aid 350 It can be removed from component 310 that is worn on the belt. This elastic jump insert 350 can be Easily removed and placed in the user's ear. One time extracted, the RF transceiver of the headset 305 is preferably activated automatically (at be detected that it is no longer in electrical contact with the first component 310), which allows voice calls to be directly (or indirectly) received by this component 305. When headset 305 is adjusted again by elastic jump in its compartment within component 310 that is carried to the belt, the RF transceiver located in the headset 305 is preferably disabled. This disconnection or shutdown automatic headset transceiver provides a method to hold all calls and send them Directly to mail or voice messages. When the first component 310 detects that headset 305 is in the compartment, will answer any incoming voice calls 95 by sending a message back to redirect device 120, which indicates that the call cannot be accepted and must be routed to the user's mail or voicemail system.

Figure 7 is an electrical block diagram of a mobile device 100 provided by way of example and that It is shown in Figures 4-6. The figures 4-7 illustrate an example provided type of mobile device 100 that can be used with the system that Here it is described.

When the second component 305 is placed in the first component 310, a shared secret can be exchanged between the two wireless components of the mobile device 100, such so that any communications between the first and second 305/310 components can be encrypted. Also the battery rechargeable 336 of second component 305 can be recharged by the battery 334 of the first component 310 by means of the circuit of 334 power supply recharge when the two components are They are in electrical contact.

In other embodiments, the mobile device may include a camera component intended to present visually or send video images to the mobile user, or may include detector circuits to monitor information vital of the mobile user, such as pulse and blood pressure. In these embodiments, the first component may carry a nurse or doctor located on the ground floor of a hospital, in so much that the second one can be found in a room patient supervising some vital statistical data. The short-range communication can reach, in this example, up to a few hundred meters and several second components can Be in communication with a single first component. This information can then be sent from the first component taken by the nurse or doctor to a station central nursing to be seen and monitored by all nurses in charge.

An example of how the mobile device 100 shown in Figures 4-7 can be used With the system described here, it is as follows. When they arrive voice calls to the user's desktop computer 120, the 110 short range wireless hanger informs the computer desktop 120 about whether it is able to route the call directly to component 310 of the user's belt. If he user is within a distance suitable for communication of the hanger with capacity for RF 110, then the call is routed directly from desktop computer 120 to belt component 310, through the communication path short range wireless, and then from the first component 310 to the earpiece component 305. Alternatively, the call can be routed directly to the second component 305. If, on the contrary, the mobile device 100 (and therefore the mobile user) is out of reach of the interface hanger 110, or is under coverage poor, or you are experiencing congestion problems, then the call is routed from the host system of desktop 120, through the 135 long range wireless network, 145, 150, to the first component 310 of the device user mobile 100. Once the call has been received from the network long range, the first component 310 then routes the call to the headset component 35 of the user and the call telephone is completed, preferably, without any of the parties involved in the call know that the new one has occurred routing

In one embodiment, the headset component 305 and belt component 310 include both short-range RF transceivers that they communicate with the RF-enabled interface hanger 110. Using this embodiment of mobile device 100, the calls voice are routed directly from the hanger 110 of interface to headset component 305 and data messages from information is routed from interface hanger 110 to belt component 310.

The mobile device 100 may also include a voice interface of the natural language type between the component  305 headset and belt component 310. This interface allows the user to interact with the belt component 310 and issue a series of instructions or voice orders, such as: "Directory services", "Find name: Gary", "Select Gary M." or "Call Gary." In this series of orders provided by way of example, the interface, which is, preferably, an interface based on programming or software that works on belt component 310, you will find, preferably, several "Garys" and will then urge the user to select a specific "Gary". Voice interface it can also allow the user to issue voice commands that are pronounced before the microphone of the second component 305, such like "accept call", "route call", "reject call "and" send call to voicemail ".

Using the voice interface, for example, the user can, in an important business meeting, suspend temporarily voice calls, but allow them to reach you messages from your secretary in the case of an emergency. Or the first component 310 may be configured to transform into voice for the user ID information (identification) of the caller on incoming voice calls, through the second component 305, such that the user can decide whether answer the call. The first component can, for example, play a message in the second component 305, such as "has a call from Gary Mousseau; say` `Accept '' to accept the call or anything else to send the call to voicemail. "Alternatively, the first component 310 can vibrate in order to indicate that a voice call is coming, instant when the user can extract the first component and Observe a visual presentation of the caller's ID. TO then the user can interact with the devices input of the first component 310 in order to accept the call, send it to voicemail, or hang up or interrupt the communication with the caller. In this way, the mobile device 100 can function as a hands-free call unit to receive and transmit voice calls, in addition to receiving and transmit a variety of data types.

Figure 8 illustrates a first user 350 of a mobile device 100 such as the one shown in the Figures 4-7, which communicates by a first way of communication comprising a short-range wireless link, and a second user 360 who has a mobile device such as the shown in Figures 4-7, which is communicated to through a second communication path comprising a link long range wireless. In this Figure, the first user 350 It is located in the vicinity of an interface hanger 110 RF capable, but the second user 360 does not.

The first user 350 is found, preferably, in your office and you have removed the second component 305 of the first component 310 of the mobile device 100 and has placed, as indicated by numerical reference 305, in its ear. As voice calls or data messages arrive to the system of the user's desktop 120, the voice calls are, preferably, directed directly to the second component 305,  while voice messages are transmitted to the first component 310. Alternatively, voice calls can be routed to the first component 310 from the RF interface of the interface hanger 110, and the first component 310 will transmit then the voice calls up to the second component 305. The user's desktop system 120 may be operating in mode of redirection device 130, or it may be working over a LAN, in combination with a device 225/130 redirection based on a network. The interface hanger 110 it also has a 605 antenna to communicate with both the headset component 305 as with the first component 310.

User 350 can configure the device redirection 130 such that, if the first component is placed on interface hanger 110, then the device redirect 130 stops redirecting data to the first component 310. In this example, the action of placing the device mobile 100 on hanger 110 operates as a trigger to stop and start redirection. In a similar embodiment, the placement of headset 305 in the holder of the first component 310 deactivates or disconnects the redirection of voice calls to the ear of the user from the first component 310. In this last example, if headset 305 is located in the first component 310, which, at in turn, it is placed in the interface hanger 110, then the "traditional" phone or the user's computer may be set to ring when a voice call arrives.

In the lower part of Figure 8, the second user 360 has moved outside the vicinity of any of the RF-enabled interface hangers 110. In this instant, headset 305 preferably detects that it no longer cannot establish RF contact with an interface hanger 110, and therefore establishes RF contact directly with the first component 310. Similarly, the first component 310 detects that neither can it establish an RF link with hanger 110 of interface nor, consequently, maintain an RF link for data and voice, such that the first component 310 activates or connects its long range RF transceiver for establish contact with the long range wireless network. How has been discussed above, when the mobile device 100 interrupts contact with interface hanger 110, it provide contact information to the redirect device 130, so that it can determine whether to redirect the information through the long range RF network.

Figure 9 is an extension of Figure 8 and shows users 350/360 moving around the environment of a office outside it, to an environment beyond the office. The office shown in Figure 9 may include a plurality of RF-enabled interface hangers 110, which form a plurality of wireless "cells" to which it is made reference here as peak-cells. According to second user 360 goes back and forth in the office, it is preferably connected and reconnected to whatever the short-range peak cell that is located more close to it (that is, to interface hanger 110 capable of RF that closer). As the user connects, disconnects and reconnects to the plurality of interface hangers 110, its Physical presence is detected under RF connections, and routing information is then provided from the hangers 110 to redirect application 130, which is preferably operating on network server 225. The redirection application 130 then uses this information from contact to alter the position to which they are redirected the User data elements. Thus, according to user 360 moves from one peak cell to another peak-cell, its data elements are automatically redirected to wherever you are physically.

As the data items arrive redirected 95 (voice and data) for user 360, these are routed to the correct desktop computer and sent directly through the interface hanger 110, to the headset 305 of the user or component 310 taken to the belt. Given the data transport capacity of the company's current LANs, that is, transmission speeds of 10 megabits or 100 megabits, it is also possible to multiplex more than one voice call or exchange data with a mobile device through it interface hanger 110. In this way, you can serve more of one user for each of the plurality of hangers 110 of Interface. As the user leaves the office environment and, therefore, the scope of the peak-cell network of the office, it is detected by the system and the device redirection then routes any data elements incoming through the long range wireless network, up to 100 mobile device.

In this way, voice and data can be routed behind the company's firewall and LAN space of wirelessly, to the position at that time the mobile user As the user moves from one side to another from the office space, all your phone calls, data messages and emails will be routed to the mobile device 100 through the network of peak-cells. Only if the user leaves the physical proximity to the office space, or if coverage within the office space is insufficient, they will be then data items redirected to mobile device 100 to over the long range wireless network. Figure 10 is also a continuation of Figure 8 and shows the users 350/360 moving through a first office environment and entering a second related office environment, located in a position physics different from that of the first office environment. In this context, there may be only a short period of time in the that the user's mobile device 100 may need to use 720 long range network, such as when the user is traveling outside the company's offices.

As user 360 moves from the location of the first office to the location of the second office and enters Office 4, 805, and Office 5, 810, the mobile device 100 of the user is put back into communication with one of the plurality of interface hangers 110, which acts as peak-cell. In this case, the information about the user's position to a network server that it serves the second office location, and it is then communicated, through a virtual private network (or VPN - "virtual private network ") 815, for a wide area network, with the redirection application that operates at the first location of office. In this way, the redirection device knows that the user is in a particular position of the second office and is able to redirect voice and data information of the corresponding user.

VPN 815 can be created with a connection of high-speed point-to-point through ISDN circuits [Network Integrated Services Digital - "Integrated Digital Services Network "], Plot Referral or T1. Alternatively, many companies create VPN's 815 over the Internet, with devices of special security routing at both ends of the Connection. The multi-cell peak solution offices shown in Figure 10 is advantageous because increases the speed at which the data is redirected and reduces the price of re-routing data items 95 to the user. Generally, long-range wireless data networks They can be expensive to use. In this way, by redirecting the data through the expensive long range network only when it is absolutely necessary, the system described here provides  a less expensive wireless redirection solution.

Figure 11 is a logical flow chart that illustrates a series of steps provided by way of example and executed by a redirection application that operates on a system principal or host in order to determine which path of communication should be used to route data elements to a particular mobile device. This flow begins either in the stage 905, either in stage 945. In stage 905, it is provided RF return information from mobile device 100 to one of the plurality of interface hangers 110. On stage 945, data elements such as voice calls or messages from digital data arrives at redirect application 130 from a particular mobile device user.

In step 910, the system determines if the Mobile user has changed position. This exchange information can be generated (1) if the user leaves RF coverage with the closest range RF link provided by a interface hanger 110, or (2) if the user returns within The short-range coverage of an interface hanger 110. In In case the user has entered the short RF coverage scope of an interface hanger, then, in step 915, the Headset component 305 of mobile device 100 sets, preferably, contact with interface hanger 110 more near. A program that is working in combination with the interface hanger 110 then receives the contact signal from the interface hanger 110 and records or records this information, as indicated by reference 920. Yes, alternatively, the user has just left RF coverage short-range interface hanger 110, then, in the step 925, the earphone component 305 will come into contact with the component 310 that is worn to the belt and belonging to the device mobile, and the interface hanger 110 will detect that the RF link previously set has been interrupted. Hanger 110 detects that the RF link is absent when performing a PING [Search of Internet Addresses - "Packet Internet Groper"] newspaper at the protocol level in order to check the presence of one or more 305 headset components. This contact information it is then transferred from the interface hanger 110 to the program which operates in combination with the interface hanger 110, in which It is temporarily stored. In any case (setting contact or interrupting the contact), the contact information you sign up for a user profile in step 935, for your Further recovery as indicated by reference 940.

The user profile can be maintained in the desktop system 120 provided as a example shown in Figure 1, in which the application of redirect 130 is working on the desktop system host. Alternatively, the user profile can be transferred through the LAN to network server 225 in the example shown in Figure 2. In any case, the application of redirect 130 has access to more contact information recently registered from the plurality of hangers 110, to from which you can determine where to redirect the User data elements.

In step 945, voice and data elements 95 addressed to a particular user, arrive at the system. One time received the elements, the redirection application interrogates the database 940 of the user (in which the user profile) to determine if it is possible to reach the user through one of the one or more peak-cells generated by the plurality of interface hangers 10. If he user is currently marked as achievable through the short range RF network, the data elements are then encoded and routed to the appropriate interface hanger 110. The coding stage ensures that security is maintained between the hanger 110 and the mobile device 100. If the user leaves Short range RF network coverage just at the moment in that the data elements are about to be transmitted to you, then the system detects this contingency and returns to the use of the Long range RF network as described in step 970. A Once the data item has been encrypted and sent to the hanger 110 interface, is preferably received and (1) well transmitted directly to headset component 305 if it is a voice call, or (2) well transmitted directly to the component 310 that is taken to the belt, if it is a data message. If the Database 940 indicates that the user is not within reach of the network short-range RF, then the data element is encoded for its long distance RF transmission in stage 970 and is transmitted to the user's mobile device 100 over the network Long range wireless Preferably, the scheme of encoding that is used for long RF transmission range is different from that used for RF transmission of short range.

Figure 12 is a logical flow chart that illustrates a series of steps provided by way of example and executed by a redirection application that operates on a system host in order to determine which communication path has been to use to route data elements to a mobile device particular within a business environment that has a plurality of office locations. The stages shown in the Figure 12 are similar to those described above in relation to with Figure 11, but they add support to a large company with branch offices and numerous pico-cells located throughout the locations of the company.

The method starts in step 1005 or 1055. In step 1005, return information is received by the system RF from mobile device 100, preferably in one of the plurality of interface hangers 110. The hanger 110 of interface works in combination with a system program that determines, in step 1010, whether the particular mobile device 100 is contacting interface hanger 110 or interrupting it In case the mobile device 100 is interrupting contact with interface hanger 110, then, in step 1030, the headset component 305 sets contact with component 310 that is carried to the belt (instead of with the interface hanger 110) and, in step 1035, the hanger Interface 110 determines that it is no longer in communication with the 305 headset component and records this absence information contact.

If, on the contrary, the mobile device 100 is establishing contact with interface hanger 110, then, in step 1015, the headset component 305 sets contact with the interface hanger 110 and, in step 1020, the system determines if mobile device 100 is setting contact with a new peak-cell (that is, with a hanger 110 of different interface). In the event that the 100 mobile device is not making contact with a new interface hanger 110, then the method is referred to the stage 1005 and awaits additional RF return information from the mobile device 100. If, on the contrary, the mobile device 100 is making contact with a new hanger 110 of peak-cell, then control goes to the stage 1025, in which the system records contact information that includes information that identifies the interface hanger 110 of concrete peak-cell.

In step 1040, the contact information from steps 1025/1035 is then provided to the redirect application 130, which stores this information in the appropriate user profile 1050. In the event that the system include multiple redirection applications (and, perhaps, multiple user profiles), then, in step 1045, the information of contact is propagated from the first redirect device to the other redirection applications that may be in operation in other locations of the company.

As the data elements are received by the redirection device (or the plurality of redirection devices) in step 1055, the device redirect reads user profile 1050 in order to determine the approximate physical position of the user. If the user is at scope of one of the interface hangers 110 of peak-cell, as determined in step 1065, the control then goes to step 1070, in which the elements of data is encrypted and routed to interface hanger 110 appropriate. The interface hanger 110 then transmits the data elements to mobile device 100 through the path of short range communication If the user is not reachable by one of the interface hangers 110 of peak-cell, then, in step 1080, the system determines if the data elements should be redirected (as has been configured by the mobile device user) and, in case So, the data elements are then coded and routed outside the company's firewall to the wireless network wide area, and transmitted to the mobile device 100 on the stage 1085
