Description

Search communications system, location and contact establishment of people based on profile selection and operator intermediation.

It consists of a communications system for the search for people who respond to a certain profile, your location in an area close to the device and setting in Device contact with the person sought. The system you will need the intervention of a central device (7) that is will communicate with the two intervening devices, without which no the location and contact can be concluded.

The system is formed p. ex. For several Personal communications devices (4) with at least two wireless communications interfaces, a central device intermediate with at least one wireless communications interface (7) and one or more application distributor devices with at least one wired communications interface (3).

The personal device (4) may be customized by its holder and will be able to send through one of your wireless connections, automatically, messages coded and partially encrypted of profile data required. In addition, you will be able to receive through one of your wireless connections, automatically, encrypted messages and partially encrypted of the profile data required by Other users. This can check if the profile received is corresponds to the own one, in which case the user will be notified (e.g. through an alarm), otherwise it will save the message for subsequent remissions.

The exchanged messages are encoded containing profile and location information, also partially encrypted to require operator mediation.

The messages exchanged are only intelligible to the devices (4) after the intervention of the central server (7).

Background of the invention

People tracking systems (US20030210186) for different types of personal electronic devices are known. These systems are limited to determining the position of a Mobile Personal Terminal (such as a personal electronic phone book, PDA or smartphone mobile phone ) within a coverage area of a wide area network, but do not serve to contact Two users neither select one type or another of user depending on their characteristics.

On the other hand, communication systems that offer personalized services to personal electronic assistants are also known according to their situation / location (DE19819582 A, WO200379655 A1) and other systems that in addition to personalizing the services offered according to their situation / location also they offer the personal assistant some services or others depending on the profile, preferences and characteristics of the users.
(EP 1455545 A1, US20040219914 A1, FR 2844126 A1).

There are inventions that have taken advantage of systems such as those described above to aid self-service purchase systems (US2004756632) through an intermediary (or broker ) resident in the personal assistant (US20030236729 A1).

All the aforementioned systems are based on the existence of a hierarchical network of nodes with a central node that must always be accessible in order to provide the service. The user's terminals are passive elements of the system and the existence of concentrator points (or hotspots ) is mandatory.

Closer to the invention that is intended protect, there are also personal assistant devices (and systems) with logical information search mechanisms that organize and reorganize the data obtained (even through wireless interfaces) depending on the characteristics of the profile entered by its owner (EP 1450517 A1). These same mechanisms have also been used to search for people with a certain profile and close location (WO2004043026 A2).

These last systems, like the invention that is intended to protect, allow search, location, and contact of two people, through the use personal assistant devices (e.g. mobile phones) with several network interfaces, at least one of long range (e.g. GSM) and at least a short range (eg Bluetooth) of according to certain characteristics (introduced by the user who can customize an application resident in their assistant). This search is performed in a decentralized manner and treating the information contained in electronic devices as a distributed database that is accessible through the Short-range interface of personal assistants.

These systems, being decentralized, overcome the problems presented by the aforementioned. They take full advantage of end-user devices, which are no longer merely passive, and extend the search capability outside the reach of hub points (or hotspots ).

However when using a mode of decentralized operation without any controlling element unique, they cannot offer commercial services because they cannot control the use of the service and perform its subsequent billing.

In addition, the distributed profile database accessed by a terminal is limited to the characteristics personnel of only the users that are within the Short range network interface reach. The limit on the scope of the search together with the impossibility of billing, make impractical current systems for service provision commercial.

Explanation of the invention.

To overcome these inconveniences: no provision of commercial services due to lack of billing and search area restriction to devices only nearby, a system that combines technologies has been devised existing for the search, location and contact of users, with cryptographic techniques that allow intermediation of a centralized body capable of carrying out billing functions In addition, to extend the coverage of short-range network interface of user terminals, these are enabled for the retransmission of packets of information to third parties.

The explanation of the invention:

The system to be protected consists of personal personal assistant terminals (4), devices distributors of portable code applications (3) and service management and billing devices (7). The Personal assistants must be enabled for download, interpretation and execution of portable code applications. The download, interpretation and execution of the code application portable is done through the acquisition subsystem of applications (Figure 1).

The user, through the mobile terminal can request code download by sending packages of specific information to one of its network interfaces. The code portable, initially resident in the distributor device, is installed in the mobile terminal and is customized by the user of according to their characteristics and the profile of the person who You want to locate and get in touch. The user can customize your application through a graphical user interface easy to use

Once the customization of the portable application, this is a resident running within the mobile terminal The portable code application accesses Periodically to the short-range network interface to send messages in which the content of the User characteristics as well as their preferences. Simultaneously, the portable code application accesses periodically to the short range interface to check if They have received messages.

The messages are sent by multicast ( broadcast ) to all devices in the near environment (Figure 2). This process creates two types of relationships between existing mobile terminal devices in the system: direct transmission ratio and indirect transmission ratio.

Direct transmission relationship is understood the one in which the receiving device of the information packet It is the final recipient of it. This fact may occur because the profile contained in the message matches that of the recipient of the package, in which case the package has reached its destination, or because the information package runs out of time lifetime.

We define life time as the number of times that a packet of information / message can be retransmitted. A life time equal to zero limits the coverage area of messages to only those who have direct visibility with the transmitter. A lifetime equal to 1 allows a retransmission ... and so on.

Indirect relationship is understood as that in that the sender or receiver of the information packet is not the sender or recipient of the message. In other words, it indirect relationship is one that is the result of a Relay The retransmissions are also made by multicast

All mobile terminal devices they contain a module of logical interpretation of the content of the posts. The result of the interpretation may be COINCIDENCE POSITIVE AND NEGATIVE COINCIDENCE.

The POSITIVE MATCH case occurs when the received message contains search information equal to User characteristics

The case of NEGATIVE COINCIDENCE occurs when the received message contains search information different from user characteristics.

In case of POSITIVE MATCH the terminal mobile lets you know by any of its resources (sound of alarm, display flashing ...) that a message has been received coincident. The received package is stored in memory and is not Forward

In case of NEGATIVE MATCH the terminal mobile decreases the lifetime of the information package and passes it to the relay module for later forwarding.

The information packets sent contain coding of user profile features searched as well as the encryption of contact data. The Package fields that are sent encrypted are not interpretable by the mobile terminal when you receive them.

The data packet fields that are encrypted, they are encrypted by the cipher module itself mobile terminal before sending. Data encryption is performed using a key result of the combination of the identity of the mobile terminal and a parameter present in the Portable code application and generated by the distributor.

Once POSITIVE MATCH has been detected through any of the signals available in the terminal, the Portable code application presented by the display, the headset, or any other means the question to the user of the terminal: DO YOU WANT TO REQUEST CONTACT WITH A MATCHING PROFILE? In case the user answers affirmatively, the application of Portable code will automatically send a message, using the Long-range network interface, to the contacting subsystem. The message will contain the identity of the requesting terminal, which will be used for billing of the commissioning service contact and request the parameter needed to decipher the content of the information packet stored in the memory of the mobile terminal

After service billing, the central device (7) sends a return message, through the Long-range network interface, to the requesting mobile terminal, containing the requested parameter. When you receive the message, the mobile terminal decoder module will be able to generate the decryption key to interpret information from terminal contact with profile equal to the characteristics of search.

When all the package information of information is accessible by the mobile terminal, the application of portable code will present to the user the question: WANT TO PUT ON IN CONTACT WITH A COINCIDENT PROFILE ?. In case of response Yes, the application resident in the mobile terminal will perform an automatic call, through the long network interface reach the contact information of the other terminal. All identities of mobile user terminals have remained anonymous, although there is a possibility that they will be revealed.

Brief description of the drawings

To improve understanding of how much has been exposed, a drawing is accompanied in which, schematically and so only as a non-limiting example, a case is represented practical implementation.

In said drawing, figure 1 is a view schematic of the portable application acquisition subsystem object of the invention.

The subsystem is composed of a device user terminal (1), such as a GSM mobile phone, with at least two network interfaces, one short range and one of long range (2). The terminal may have a display monitor of text and images and a headset like those present in the traditional cell phones. Also the terminal also It can consist of a microphone and a camera that allow the capture of voice, and images by the user. Finally the subsystem it also consists of an application distributor device portables (3) such as, by way of example, a computer / server with web interface and http server capable of Respond to requests to download content. For this function the application distributor device may have a wired Internet connection that allows communication with the terminal device (1). Another possible implementation of (3) may consist of a personal computer connected to a GSM / GPRS MODEM and SMS messaging software capable of responding to requests from Download information via SMS.

Figure 2 is a schematic view of the search and location subsystem, also object of the invention. The subsystem consists of an indefinite number of mobile terminals such as the one described above (4), randomly located in space and capable of communicating with each other thanks to the short-range network interface. The connections between them can be wireless in nature, using technologies such as Bluetooth, ZigBee or WLAN in ad-hoc mode. There are two types of communications: direct transmission of information packets (5) and indirect transmission of information packets (6). In the direct transmission of information packets, the sender and recipient of the information correspond to the transmitter and receiver of the packets. In the indirect transmission of information the sender or recipient of the information does not have to correspond with the actual transmitters / receivers of the same. We say then that information packets are forwarded by third parties.

Figure 3 is a schematic view of the contact subsystem. It is formed by terminals personal as described above (4) and a device central (7) with at least one long wireless network interface range (eg GSM / GPRS).

The central device can communicate with all mobile terminals (4) over the long network range through non-permanent wireless connections (8).
