Abstract

The method for transferring data sends the data as part of first and second permanent identifiers during a communication procedure prior to establishing a traffic channel in the communication system. Besides the data, the first permanent identifier includes routing information to a home system forming part of the communication system. The second permanent identifier is an expanded permanent identifier with the data forming at least part of the expanded portion thereof. Based at least on recognizing a portion of the second permanent identifier, a home system sends the first and second permanent identifiers to a destination entity. The destination entity extracts the data from the first and second permanent identifiers. In this manner, a traffic channel does not need to be established to transmit the data.

Description

METHOD FOR DATA TRANSFER Field of the Invention The present invention relates to the field of communication, and more particularly, to a method for data transfer.

Description of the Related Art Figure 1 illustrates a logic block diagram of a conventional communication system that provides mobility. This logic block diagram represents either wired or wireless communication systems (or landline) that provide mobility to the subscriber. As shown, an end user 2 communicates with a destination entity 6 by means of a first communication device 4, a service system 12, a network 14, a source system 16, and a second communication device 8. The end user 2 represents an entity (person, system or machine) which generates information for communication to the target entity 6 (also a person, system or machine). The first communication device 4 represents a device for interconnecting with the service system 12. For example, taking the REF .: 32887 wireless communication as an example, the service system 12 includes any number of base stations, mobile interconnection centers, authentication centers, etc. to provide wireless communication services for a coverage area in which the communication device 4 is located, and the communication device 4 represents a mobile station. Continuing with the wireless communication example, the network 14 presents a public or private communication network such as the Public Switch Telephone Network, a public packet network or a private packet network, and the home system 16 represents the service provider of wireless communication with whom the user of the mobile station (i.e., communication device 4) has established an agreement to provide the mobile wireless communication services. Therefore, the source system 16, similar to the service system 12, also includes any number of base stations, mobile interconnection centers, authentication centers, etc. to provide mobile wireless communication services for a coverage area. Because a particular mobile wireless communication service provider has a limited coverage area, service providers have different long-range location (roaming) agreements established in the coverage areas to serve each of the customers. In this example, the second communication device 8 may be a mobile station or a wired connection to the home system 16. Alternatively, in this example or any other mode, the second communication device 8 is connected to the home system 16 by means of of a network such as the network 14. As a further alternative, the second communication device 8 forms part of the home system 16. As an example of how Figure 1 represents a wired mobile communication system, the service system 12 represents the mobile landline communication service provider for the location in which the communication device 4 is located, the network 14 represents, for example, a long-distance landline carrier, and the originating system 16 represents another provider of the terrestrial mobile communication service with whom the end user 2 has established an agreement to provide the services of commu mobile landline communication. The first communication device 4 will then be able to represent a smart or programmable telephone. One mode of a smart phone allows the end user 2 to place a programmed IC card in the smartphone, and converts the smartphone into the personal telephone of the end user. That is, the programmed integrated circuit card provides the smartphone with the subscriber information for the end user 2 such that communication of this information to the service system 12 and communication between the service system 12 and the origin system 16 permit, for example, (1) calls to the end user 2 addressed to the smartphone (i.e., the communication device 4) or (2) the end user 2 originates the calls in the service system 12 as if he were still in the area served by the source system 16. The examples of wireline and wireless lines given above provide only two examples of several possible mobile communication systems represented by Figure 1. The mobile communication systems represented by the logic block diagram of the Figure 1 present various challenges to the service system 12 and the originating system 16 that wishes to provide communication services only to validated users and receive an appropriate payment for having provided these services. Accordingly, each communication system has associated therewith numerous different standards and protocols to ensure that the aforementioned objectives are achieved. The most prevalent techniques employed by these standards use permanent identifiers associated with the end user 2. One of the identifiers is assigned by the source system 16, and referred to hereinafter as the first permanent identifier. The first permanent identifier includes two portions. The first portion includes information addressed to the source system 16, and identifies the source system 16 with which the service system 12 must communicate. The second portion of the first permanent identifier identifies the end user 2 for the source system 16, and is often an identification number. Several wireless communication standards refer to the first permanent identifier as the mobile station identifier (MSID).

An example of the first permanent identifier is the International Mobile Station (or Subscriber) Identification (IMSI) specified by the International Telecommunication Union - Telecommunication Sector (ITU-T) Recommendation E.212. The format of the IMSI is provided below: IMSI (above 15 digits) = MCC (3 digits) + MNC (1 to 3 digits) + MSIN (9-11 digits) The mobile regional code (MCC) forms the first three IMSI digits and identifies the region in which the source system is located 16. Along with the mobile network code (MNC), which forms the next 1 to 3 digits, the MCC forms a source system code that identifies to the source system 16. Communication standards in the United States often refer to this source system code as the originating network identifier (HNI). The next 9-11 digits form the preassigned identification number to the end user 2 by the origin system 16. Another identifier of the permanent user (hereinafter "the second permanent identifier"), while known by the originating system 16 and associated with the end user 2, it is not necessarily assigned by the source system 16. This identifier is also associated in the same way with the first communication device 4 or a portion thereof used by the end user 2. In a communication system mobile wireless, the second permanent identifier may be the electronic serial number (ESN) of the mobile station that serves as the first communication device 4. In a wired mobile communication system such as the smart telephone example discussed above, the second permanent identifier it may be the serial number of the integrated circuit card programmed. The second permanent identifier may even be the telephone number of, for example, and the Integrated Services Digital Network (ISDN) telephone. There are plans to expand the second permanent identifier in the future. The second expanded permanent identifier includes three portions. The first and second portions generally represent the second unexpanded permanent identifier, while the third portion represents the expanded portion of the second permanent identifier. The first portion includes a code. When this code is a preset code, the second expanded permanent identifier is activated. Accordingly, this technique allows the use of either the second non-expanded or expanded permanent identifiers. If the second expanded permanent identifier is activated, the system or device that receives the first and second portions of the second expanded permanent identifier will wait for the third portion to continue, and if the third portion is not received, a request for it will be generated. When the first portion of the second permanent identifier does not include the preset code, the first portion represents a first identification number as in the second unexpanded permanent identifier. The second portion of the second permanent identifier, and also the second expanded permanent identifier, include a second identification number. The expanded portion represents a third identification number. An example of a second expanded permanent identifier is the expanded ESN (EESN) currently proposed for wireless communication. The format of the EESN is provided below: EESN (56 bits) = ESN (32 bits) + expansion of ESN (24 bits) ESN (24 bits) = manufacturer code of 128 (8 bits) + identification number (24 bits) expansion of ESN = code of the expanded manufacturer (24 bits) When the manufacturer code is 128, the expanded ESN is activated. The source system 16 typically stores the first and second pair of expanded permanent identifiers for each subscriber as the end user 2. When communicating with the service system 12, the communication device 4 supplies the first and second expanded permanent identifiers to the service system 12. Based on the information route in the first permanent identifier, the service system 12 knows the communication with the origin system 16 for, for example , validate the end user 2. To validate the end user 2, the service system 12 provides one or both of the first and second permanent identifiers expanded to the source system 16. Normally, if the source system 16 receives only one of these identifiers , the source system 16 will request the other identifier of the service system 12. In addition, if a second expanded permanent identifier is provided without the third identification number or expanded portion, the origin system 16 will request to request the expanded portion. If the first permanent identifier and the second expanded permanent identifier provided by the service system 12 are equal to the pair of the first corresponding permanent identifier and second expanded permanent identifier stored in the source station 16, the origin station 16 validates the end user 2 This process can also be used as part of a procedure to verify (for billing purposes) or authenticate (to eliminate fraud) the end user 2. Referring again to the wireless example, this validation process is normally performed as part of the procedure of registration included in more wireless communication standards. Once validated, the service system 12 provides the communication services to the end user 2. For example, in a wireless system, a service system 12 will open a traffic channel for a valid mobile station upon receiving such a request from the mobile station by the end user 2 that originates the call. Having opened this traffic channel, the end user 2 can now transmit data to the destination entity 6. There is, however, a need for the end users to transmit data more efficiently which are available through a long process of requesting and establish a traffic channel.

Brief Description of the Invention The method for transferring data according to the present invention forms a first permanent identifier associated with an end user (person, system or machine) in a mobile communication system. The first permanent identifier includes information addressed to a source system in the mobile communication system, and also includes data associated with the end user in a predetermined portion thereof. An expanded permanent identifier is also formed. The expanded portion of the expanded permanent identifier includes data, and another portion thereof, associated in some way with the end user, serving to identify the end user. A communication device in the mobile communication system used by the end user sends the expanded permanent identifier and the first permanent identifier, both intended for the originating system. Based on the expanded permanent identifier, a source system can recognize the end user associated with a pair of the first permanent identifier received and the expanded permanent identifier, and at least according to this recognition, sends the first permanent identifier and the permanent identifier expanded to the destination entity (person, system or machine). The destination entity extracts the data of the first permanent identifier and the expanded permanent identifier. In this way the data is transferred from the end user to the destination entity on the mobile communication system without having to establish a traffic channel.

Detailed Description of the Drawings The present invention will come to be understood more fully by the detailed description provided below and the accompanying drawings which are provided only in an illustrative manner, wherein like reference numbers designate the corresponding parts in the various drawings. , and wherein: Figure 1 illustrates a logic block diagram of a conventional communication system; Figure 2 illustrates a logic block diagram of a system modality for the end user in Figure 1; Figure 3 illustrates a logic block diagram of a system embodiment of the target entity of Figure 1; and Figure 4 illustrates a logic block diagram of a mode of a communication system according to the present invention.

Detailed Description of the Preferred Modes The method of data transfer using the conventional communication system illustrated in Figure 1 will be described. Accordingly, a description of the elements illustrated in Figure 1 will not be repeated. As discussed above, the numerous standards and protocols associated with the various mobile communication systems represented by Figure 1 will employ a first permanent identifier and a second expanded permanent identifier. To transmit data, the communication device 4 initiates a procedure within the standard or protocol that requires the transfer of the first permanent identifier and the second expanded permanent identifier. For example, in a mobile wireless communication system, several standards require the mobile station to transmit the first permanent identifier and the second expanded permanent identifier as part of the registration procedure.

However, the communication device 4 forms the first modified permanent identifier and the second expanded modified permanent identifier prior to transmission. Alternatively, the end user 2 supplies the communication device with the first modified permanent identifier and the second modified expanded permanent identifier. The term "modified" is used herein to denote a difference between the first permanent identifier and the second expanded permanent identifier created according to the present invention and its conventional counterparts, and does not necessarily mean that either the communication device 4 or the user end 2 modify the first existing permanent identifier and the second expanded permanent identifier; although also the present invention is contemplated to cover this alternative. The first portion of the first modified permanent identifier contains the information addressed to the source system 16, but the second portion or a portion thereof, which normally includes the user identification number pre-assigned by the originating system 16, includes the data of the end user 2.

The first portion of the second modified expanded permanent identifier includes the preset code for activating the second expanded permanent identifier, and the second portion includes an identification number when the second conventional expanded permanent identifier is made. However, the third identification number or the expanded portion of the second modified expanded permanent identifier, which normally includes another identification number, includes the data of the end user 2. For example, when the IMSI is the first permanent identifier, the IMSI modified has the format provided below: IMSI (above 15 digits) = MCC (3 digits) + MNC (1-3 digits) + data (9-11 digits). And, when the EESN is the second expanded permanent identifier, the modified EESN has the format provided below: EESN (56 bits) = ESN (32 bits) + expansion of ESN (24 bits) ESN (24 bits) = the code of the manufacturer of 128 (8 bits) + the identification number (24 bits) ESN expansion = data (24 bits) Co or part of the procedure initiated, the service system 12 supplies the first modified permanent identifier and the second expanded permanent identifier modified to the source system 16 by means of the network 14 and the second communication device 8. If the service system 12 only provides one of the first modified identifier and the second expanded permanent identifier, the origin system 16 requires the other identifier. If the source system 16 does not receive the expanded portion of the second modified expanded permanent identifier, the source system 16 requires the expanded portion of the service system 12. The source system 16 compares the first modified permanent identifier and the second modified permanent identifier. expanded to the pairs of the first stored permanent identifier and the second expanded permanent identifier. If the source system 16 finds an equalization between the second portion of the second modified permanent identifier received and a second portion of a second stored expanded permanent identifier, but the first modified permanent identifier and / or the expended portion of the second modified expanded permanent identifier received is not equal to the stored counterpart associated with the second stored portion, equalized from the second expanded permanent identifier, then the origin system 16 recognizes that the first modified modified permanent identifier received and the second modified modified permanent identifier stored the data. When the source system 16 recognizes that the first modified modified identifier received and the second modified modified permanent identifier store the data, the source system 16 sends the first modified modified permanent identifier received and the second modified permanent identifier expanded to the destination entity 6. associated with the second stored stored portion of the second permanent identifier expanded by means of the second communication device 8. The origin system 16 also fails to validate the first communication device 4 for the service system 12. As a result, the service system 12 has the option to deny the service to the first communication device 4. Based on the first modified modified permanent identifier received, the destination entity 6 recognizes that the first modified modified permanent identifier received and the modified modified permanent identifier originate from the user. or final 2. Further, because the first modified permanent identifier and / or the second modified expanded permanent identifier is not equal to the first permanent identifier respectively and / or the second expanded permanent identifier for the end user 2, the destination entity 6 recognizes the first modified permanent identifier and the second expanded permanent identifier modified as data containers. Alternatively, by simply receiving the identifiers of the source system 16, it is caused that it is recognized that the first modified permanent identifier and the second modified expanded permanent identifier contain the data. The destination entity 6, which has recognized that the modified first permanent identifier and the modified modified second permanent identifier contain the data, extracts the data. As one skilled in the art will appreciate, that the method according to the present invention allows an end user 2 to transfer data to a destination entity without having to request and establish a traffic channel. As previously discussed, the end user 2 can be a person, system or machine. For example, the end user 2 may be an end-user system as shown in Figure 2. Figure 2 illustrates a logic block diagram of an end-user system 100. As shown, an end-user system 100 includes a first central processing unit (CPU) 102 connected to a first read only memory (104) and a first random access memory (106). The first CPU 102 performs some function according to the received input based on a predetermined program stored in the first ROM 104. The results of the intermediate and final processing are stored in the first RAM 106. According to the programming stored in the first ROM 104, the first CPU 102 transfers the data to the communication device 2 for transmission. As one skilled in the art will appreciate, the end-user system 100 may be any of a plurality of end-user systems, such as an automated computing machine, a detection or measurement device (e.g., a gas or electric meter). ), an automatic vending machine, a vehicle, an autonomous vehicle, a robot, a security alarm system, a climate or environmental tracking system, etc., which receive input in some form, such as from a person or detector (s). Accordingly, there is a need for the end user system 100 to transfer the accumulated data in the processing of its function to a remotely located destination entity 6 associated therewith. As a more specific example, the end user system 100 may be a vehicle tracking device that measures the distance traveled by the vehicle and detects the location of the vehicle. By means of the first communication device 4, the service system 12, the network 14, the origin system 16 and the second communication device 8, the system of the end user 100 transfers the data of the distance and location to the entity of destination 6 according to the method of the present invention. In an alternative embodiment, the first communication device 4 forms part of the end user system 100 or the end user system 100 forms part of the first communication device 4. In a possible mobile wireless communication system, the first communication device 4 it is a mobile station, and the mobile station is part of the end-user system 100. As also discussed previously, the destination entity 6 may be a person, system or machine. For example, the destination entity 6 can be the processing system 110 shown in Figure 3. As shown, the processing system 110 includes a second CPU 112 connected to a second ROM 114 and a second RAM 116. The second CPU 112 performs the processing functions according to a predetermined program stored in the second ROM 114, and stores the results of the intermediate and final processing in the second RAM 116. Continuing with the example of the vehicular tracking, the processing system 110 is a system processing for a transport company that extracts the data transferred to it by the end-user system 100, and uses the extracted data to, for example, prepare the appropriate billing of the client. As an alternative, the second communication device 8 may be part of the destination entity 6, or the destination entity 6 may be part of the second communication device 8. In addition, the originating system 16 may communicate directly with the entity of destination 6 by means of a communication line (for example, fiber optics, cable, etc.); thus, eliminating the second communication device 8. The second communication device 8 may also be eliminated in another alternative mode where the destination entity 6 is part of the originating system 16 or the originating system 16 is part of the destination entity 6. As a further alternative, and preferably as part of the mode where the destination entity 6 forms a part of the originating system 16 or the originating system 16 forms a part of the destination entity 6, the originating system 16 it does not store any of the first permanent identifiers. In contrast, the source system 16 does not expect to always validate the end user 2 so that communication services can be provided to it. The source system 16 only expects to receive the data from the end user 2. Accordingly, when the source system 16 receives a second modified expanded permanent identifier having a second portion equal to a second portion of the second stored expanded permanent identifier, the system of origin 16 sends the first modified permanent identifier and the second modified expanded permanent identifier to the destination entity 6. Figure 4 illustrates another logic block diagram of a mobile communication system according to the present invention. The modality of Figure 4 is the same as that shown in Figure 1, except for the addition of (1) the third-party Mth communication devices 8-1, ..., 8-M connected to the source system 16 and (2) ) the destination entities Nth second 6-1, ..., 6-N connected to the third-party Mth communication devices 8-1, ..., 8-M. In this mode, the source system 16 supports the multiple destination entities 6, 6-1, ..., 6-N. The source system 16 stores a unique address for each of the first target entities Nth 6, 6-1, ..., 6-N. Accordingly, the data properly addressed to one of the first destination entities Nth 6, 6-1, ..., 6-N the end user 2 or the communication device 4 modifies the second portion of the first modified permanent identifier or the expanded portion of the second modified expanded permanent identifier such that a predetermined part thereof includes the unique address of the desired receiving destination entity. The remaining portions of (1) the second portion of the first modified permanent identifier or (2) the expanded portion of the second modified expanded permanent identifier are then available to send the data.

For example, it is assumed that ten or fewer destination entities are supported by the source system 16 such that a single digit could be used to uniquely identify the destination entities. It is also assumed that for the purposes of this example the first permanent identifier is the IMSI. Then, the modified IMSI may have the format provided below: IMSI (above 15 digits) = MCC (3 digits) + MNC (1-3 digits) + unique identifier of the destination entity or address (1 digit) + data (8-10 digits). While in this example, the identifier of the single-destination entity is shown as forming the first part of the second portion of the first modified permanent identifier, the single-destination entity can form any part of the second portion of the first modified permanent identifier or any part of the expanded portion of the second modified expanded permanent identifier. When handling a pair of the first modified modified permanent identifier received and the second modified expanded permanent identifier where the second portion of the second modified expanded permanent identifier received is equal to the second portion of a second expanded permanent identifier stored in the source system 16, the source system 16 obtains the identifier of the destination entity in the predetermined part of the second portion of the first modified permanent identifier or in the predetermined part of the expanded portion of the second modified expanded permanent identifier. The source system 16 then sends the first modified permanent identifier and the second modified expanded permanent identifier to the destination entity 6, 6-1, ..., 6-N identified by the identifier of the destination entity. As an alternative, the second communication devices 8, 8-1, ..., 8-M may be part of the destination entities 6, 6-1, ..., 6-N or the target entities 6, 6-1, ..., 6-N may be part of the second communication devices 8, 8-1, ..., 8-M. In addition, the source system 16 may communicate directly with one or more of the target entities 6, 6-1, ..., 6-N by means of a communication line (e.g., fiber optic, cable, etc.). ); thus, eliminating one or more of the second communication devices 8, 8-1, ..., 8-M. The second communication devices 8, 8-1, ..., 8-M can also be eliminated in another alternative mode where the destination entities 6, 6-1, ..., 6-N are part of the origin system 16. While most of the examples provided with respect to the present invention have been of wireless mobile communication systems, one skilled in the art will recognize from the foregoing description that the present invention also applies to wired mobile communication systems. The invention thus described, it will be obvious that it can be varied in different ways. The variations will not be considered as a departure from the spirit and scope of the invention, and all modifications are intended to be included within the scope of the following claims.

It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects or products to which it refers.
