DETAILED DESCRIPTION OF THE PREFERRED MODALITIES A detailed explanation of an embodiment of the present invention with reference to the drawings is the following: this mode is a radio location data transmission / reception system where the transmission data from a radio location data transmitter they are received by a radio location data receiver. For example, the radio location data transmission / reception system may consist of a transmission / reception system with transmission capacity. As shown in Figure 1, the radio location data transmission / reception system includes a radio location data transmitter 2 and a radio location data receiver 3. For example, the transmission / reception system Radio location data 1 can be constructed as an information transmission / reception system, whereby various types of information transmission from a base station can be received by means of what are called pagers. The radio location data transmitter 2 is equipped with a data segmentation block 21, a sequence information addition block 22, an information identification number addition block 23, a transmission processing block 24 and an antenna 25. The radio location data transmitter 2 constitutes a base station for transmitting location data by radio. The radio location data receiver 3 is equipped with an antenna 31, a reception processing block 32, an information identification number discrimination block 33, a memory 34 and a data restoration block 35. For example , the radio location data receiver 3 can constitute a portable and compact locator. In the radio location data transmission / reception system 1, the radio location data transmitter 2 has a data segmentation block 21 which is a transmission data segmentation means that divides the transmission data into units of transmission data segmentation to obtain data segments; the information identification number addition block 23 which is a means of adding identification information that adds a plurality of fragments of identification information to each data segment to identify the transmission data; a block for adding information in sequence 22 which is a means of adding information in sequence that adds information in sequence to each segment of data in the sequence in which it is divided; and a transmission processing block 24 which is a transmission processing means that performs transmission processing whereby the data segments to which different identification information is added are assigned within a single data transmission cycle. In addition, the radio location data receiver 3 is an information receiver that restores the transmission data from the radio location data transmitter 2 based on the identification information and information in sequence added to the data segments. .

Below is an explanation of the various blocks or circuits constituting the radio location data transmitter 2 and the radio location data receiver 3. Firstly, the radio location data transmitter 2 will be described in detail. In the radio location data transmitter 2, the data segmentation block 21 performs the division of input data. The data division is carried out in the transmission data segmentation units that are transmissible units. It should be noted that the division of data by the radio location data transmitter 2 is not always carried out, but only when the amount of transmission data is large. The transmission data that is divided by the data segmentation block 21 is provided as an input to the sequence information addition block 22. The sequence information addition block 22 adds information in sequence to the data segments. The block of information addition in sequence 22 adds numbers in sequence from 0 (zero), as the information in sequence mentioned above. As shown in Figure 2, the addition of information in sequence is effected by adding information in sequence 102 to the data segments stored in the data region 104. The data segments to which the information in sequence is added by the block of data. addition of information in sequence 22 in this manner are provided as an input to the addition block of information identification numbers 23.

The information identification number addition block 23 performs a procedure by which an information identification number of a different type is added to each data segment. The information identification number is the information that indicates the type of data segment formed from the same transmission data. The information identification number consists of a plurality of information identification numbers, by means of which it is possible to identify the data segments that come from the same transmission data. For example, if it consists of two information identification numbers, as illustrated in Figure 3B, "ID1" and "ID2" are assigned to the data segments. The addition of information identification numbers to the data segments is done concretely by adding a unique code 101 as shown in Figure 2. The unique code 101 is a code used to identify whether the source of the data segments is identical or not. , and it does not need to be completely unique, but it can be repeated. The transmission information to which an information identification number is added by the information identification number addition block 23 is provided as an input to the transmission processing block 24 mentioned above. As illustrated in Figure 3A and B, the sequence information addition block 23 and the transmission processing block 24 divide the transmission data D0 into data segments Di, D2, D3, D, D5 and D6, and add the information in sequence consisting of sequence number "1", sequence number "2", ... sequence number "5", sequence number "6" to data segments D -? - D6 from of the transmission data D0, and assign and add the information identification numbers consisting of "ID1" and "ID2" to it. The transmission processing block 24 performs transmission processing of the transmission data to which various information is added, as described above. The transmission processing block 24 allocates data segments with different information identification numbers to each of the respective groups of a data transmission cycle that employs a plurality of groups as transmission units. As illustrated in figure 3C, the data segments marked "ID1, sequence number 1" and "ID2, sequence number 2" are stored in different groups in the same data transmission cycle and sent, while the data segments marked "ID1, sequence number 3"e" ID2, sequence number 4"are stored in different groups in the next cycle of data transmission and are sent, and the data segments marked" ID1, sequence number 5"and" ID2, number sequence 6"are stored in different groups in the next data transmission cycle and are sent, and therefore the transmission processing is performed in this way. The data subject to transmission processing in the transmission processing block 24 is transmitted from the antenna 25.

The radio location data transmitter 2 adds information in sequence and information identification numbers to the data segments in accordance with the procedure illustrated in Figure 3A to C, and completes the transmission processing of the transmission data to the receiver of radio location data 3. It should be noted that the number of segments 103 can be added to the data segments as shown in Figure 2. This number of segments 103 is a value indicating the number of segments in which they are divided. Transmission data, or mainly information consisting of a number equal to 2 or greater. Upon receiving the number of data segments equal to this number of segments 103, the radio location data receiver 3 assumes that the transmission data reception in question is complete. The radio location data receiver 3 is equipped with an information identification number discrimination block 33 which is an identification information discrimination block which performs the discrimination of data segments from the information identification number, a memory 34 that is a storage medium that stores the data segments marked with the same information identification number, based on the results of the discrimination performed by the identification block of information identification numbers 33, and a block data restoration means 35 which is a restoration means that restores the data segments for each number of identification information stored in the memory 34, based on the information in sequence. In a radio location data receiver 3 having said component blocks, the transmission from the radio location data transmitter 2 is received by the reception processing block 32 through the antenna 31. The data subject to processing reception in this reception processing block 32 are subjected to discrimination of the information identification number, added to the data segments in the identification block of information identification numbers 33. To explain it according to figure 3A to C above, the information identification number discrimination block 33 discriminates between "ID1" and "ID2". Based on the discrimination results through the information identification number discrimination block 33, the memory 34 stores data segments provided as an input. For example, memory 34 can be divided into several regions corresponding to the number of types of information identification numbers. Therefore, as shown in FIG. 4A, according to the discrimination results, the data is stored in the storage memory region ID1 or in the storage memory region ID2. Here, data with sequence number "1", sequence number "3" and sequence number "5" are stored in sequence in the storage memory region ID1, while data with sequence number "2," sequence number "4" and sequence number "6" are stored in sequence in the storage memory region ID2. The data restoration block 35 extracts the data stored in the memory 34, as described above, and restores the transmission data D0 as shown in Figure 4B, based on the information in sequence and the sequential numbers added. to each data segment. Figure 5 illustrates the series of steps in the reception processing performed by the radio location data receiver 3. Here, it will be assumed that "ID1" and "ID2" are added to the data segments as information identification numbers . As illustrated in Figure 5, in step S1, the radio location data receiver 3 receives a packet, and in step S2 carries out a comparison of the ID information identification number. If it is determined that the information identification number is ID1 as a result of its ID comparison, the radio location data receiver 3 continues to step S3, but if it is determined that the information identification number is ID2, the control proceeds to step S5. On the other hand, if ID is not found, the radio location data receiver 3 does not perform the reception processing of the data in question. In step S3, the radio location data receiver 3 determines whether the data is divided or not. For example, segmentation can be determined by reference to the number of segments 103, as shown in Figure 2. If it is determined that the received data will not be divided in step S3 the radio location data receiver 3 continues to step S8 and performs the normal processing of data reception. On the other hand, if the data is determined to be divided, the radio location data receiver 3 proceeds to step S4. In step S4, the radio location data receiver 3 performs the procedure of storing the data in the memory 34, in accordance with the sequence number of the information in sequence added to the data. The radio location data receiver 3 stores the data in question in the storage memory region ID1. The processing in steps S3 and S4 described above is for the case in which the information identification number is ID1, but the same processing is done in the case where the information identification number is ID2. If it is determined that the information identification number is ID2 in step S2, the radio location data receiver 3 continues to step S5, where it is determined whether the data is divided or not. If it is determined that the received data is not divided in step S5, the radio location data receiver 3 continues to step S9 and performs the normal data reception processing. On the other hand, if it is determined that the data will be divided, the radio location data receiver 3 proceeds to step S6. In step S6, the radio location data receiver 3 performs the data storage procedure in the memory 34 according to the sequence number of the information in sequence added to the data. The radio location data receiver 3 stores the data in question in the storage memory region ID2. After performing the data storage in steps S4 and S6, in step S10, the radio location data receiver 3 determines whether all data has been received or not. Here, if it is determined that all the data has not been received, the radio location data receiver 3 once again performs the reception of the packet in step S1. If it is determined that all the data has been received, the radio location data receiver 3 proceeds to step S11 and completes the reception processing. The radio location data transmission / reception system 1 is configured as described above and performs the transmission of data from the radio location data transmitter 2 to the radio location data receiver 3. As described in advance, the radio location data transmission / reception system 1 adds an identification number of information and information in sequence to the data segments obtained by dividing the transmission data. In this way, it is possible to transmit the data segments obtained by dividing the transmission data stored in each of the groups comprising a single data transmission cycle, and therefore it is possible to send even a large volume of transmission data. that exceeds the transmission units. Furthermore, as already described, the radio location data transmission / reception system 1 performs the data transmission processing using two information identification numbers, and in this way it is possible to transmit two transmission data segmentation units. in a single cycle of data transmission. In other words, this radio location data transmission / reception system 1 can perform the reception processing of several types of data segments obtained by dividing the transmission data equal to the aforementioned information identification number in a single transmission cycle. data. Therefore, the radio location data transmission / reception system 1 can decrease the transmission time to enable high-speed transmission. In the case where the transmission data D0 illustrated in FIG. 6A is divided and only a single information identification number (ID1) is added in the six units of transmission data segmentation, as shown in FIG. 6B, it is only possible to transmit a single transmission data segmentation unit in a single data transmission cycle, so the same number of data transmission cycles as the number of segmentation units are required. However, by using a plurality of information identification numbers, as shown in Figure 3C, it is possible to transmit two transmission data segmentation units in a single data transmission cycle. In this example, the transmission time is reduced by half. In addition, with the radio location data transmission / reception system 1, the received transmission data segmentation units are stored in separate memory regions to store information corresponding to each information identification number, but information is added to the information. sequence through the transmission data segmentation unit, so after the reception it is possible to correctly register the transmission data segmentation unit to restore the original transmission data; therefore, the original transmission data can be restored even if the segments are received in disorder. It should be noted that in the description of the preferred embodiment, the original transmission data is restored by adding a number indicating the sequence, such as 1, 2, 3, ... as the information in sequence, but the information in sequence does not it is limited to these numbers, since any mode of representation can be employed, as long as the radio location data receiver 3 can restore the transmission data segmentation unit to the original transmission data. Also, in the embodiment described herein, the two identification information numbers of "ID1" and "ID2" are used to carry out the parallel data transmission, but this parallel data transmission can also be performed in the same way using three or more information identification numbers. As a result, the data transmission speed may increase more, so the greater the number of information identification numbers, the higher the data transmission speed. Further, in this embodiment, the radio location data receiver 3 stores data segments corresponding to each information identification number within a plurality of regions divided within a single memory 34 provided, but this is not a limitation. For example, it is possible to provide a plurality of memories, each corresponding to an information identification number; so more data can be stored. In addition, the transmission of data in the data transmission cycle is not limited to the transmission mode illustrated in FIG. 3C already mentioned. For example, the transmission interval may be inconstant or the sequence numbers may not be followed according to the information in sequence. An example of a case in which the numbers in sequence according to the information in sequence are not followed is the transmission mode illustrated in figure 7C, where after transmitting the data segment marked "ID1, sequence number 1" , in the next data transmission cycle, the data segments marked "ID, sequence number 3" and "ID2, sequence number 2" are transmitted in the same data transmission cycle, and then the following data segments marked "ID1, sequence number 5" and "ID2 sequence number 4" are transmitted in the same data transmission cycle. It should be noted that the division of transmission data and the addition of different information is the same as in Figures 3A and B mentioned above, mainly the transmission data illustrated in Figure 7A are divided as illustrated in Figure 7B, and the information is added in sequence (sequence number) and the information identification number (ID). In this way, although the sequence numbers according to the sequence information are not followed as shown in Figure 7C, the radio location data receiver 3 can restore the data as illustrated in Figures 4A and B. In addition, the signal scheme of a radio location data transmission / reception system applied to a locator or the like is concretely compounded as shown in FIGS. 8A to C. As illustrated in FIG. 8A, the transmission cycle of Data composed of a frame consists of 15 groups Gi, G2 Gu, G-? 5, as the data transmission units. For example, the length of the data transmission cycle may be approximately 29 seconds.

As shown in Figure 8B, each of the groups consists of a synchronized signal 201, an address / message identification signal 202, selective location signals 203 and 204, and a phase information signal 205. For example, the Address identification signal / message 202 referred to herein may indicate the order within the selective location signals in symbol units. As illustrated in FIG. 8C, the selective location signal consists of an address signal 211, an aggregate information storage block 212, and a message signal 213. Here, the message signal 213 consists of the data segments already mentioned, and the aggregate information storage block 212 contains the information in sequence mentioned above and the information identification number. It should be noted that it goes without saying that the present invention is not limited to being applied to the composite signal mode as shown in Figure 8. For example, in a data transmission scheme having a data storage region consisting of a plurality of components in the same manner as the groups already described, different information identification numbers may be added, as described above, to the data segments that are stored in a plurality of said data storage regions and transmitted. In addition, it can also adapt to the next generation signal modes.

With a composite signal as such, the radio location data receiver 3 belongs to one of the groups within the aforementioned frame and is synchronized upon receiving the synchronized signal of the group to which it belongs, and then receives its own localization signal selective within that group. In addition, a radio location data receiver 3 that has received its own selective location signal within a group will restore the transmission data as described above, based on the information in sequence and the identification number of stored information. within the aggregate information storage block 212. In addition, the radio location data receiver 3 is not limited to one application as a locator. For example, the radio location data receiver 3 can also be applied to a portable information communication terminal or a so-called Personal Digital Assistant (PDA), which retains its portable capacity while allowing communication , organization and storage of information and the like. In the information transmission / reception system according to the present invention, in the transmission medium, the transmission data segmentation means can divide the transmission data into transmission data segmentation units to obtain data segments, the identification addition means may add a plurality of fragments of identification information to each data segment to identify the transmission data, and the information aggregation means in sequence may aggregate information in sequence to each segment of data in the sequence where it is divided. In addition, in the transmission medium, the transmission processing means can perform transmission processing whereby the data segments to which different identification information is added are assigned within a single data transmission cycle. In addition, in the receiving means, the transmission data from the transmission medium can be restored based on the identification information and information in sequence added to the data segments. The information transmission / reception system can perform the transmission / reception processing of several data segments formed by dividing the transmission data corresponding to the number of types of identification information in a single cycle of data transmission. For the above, the data can be transmitted at high speed. In addition, the information in sequence for the data is added to the data segments, so that the receiving means can restore the original transmission data even in the case where the data segments mentioned above are received in disorder. Also, in the method of transmitting / receiving information in accordance with the present invention, the transmission means divides the transmission data into transmission data segmentation units to obtain data segments, adds information in sequence to each data segment. in the sequence in which it is divided, and also adds a plurality of fragments of identification information to each data segment to identify the transmission data, and assigns and transmits data segments to which different identification information is added within a single cycle of data transmission. The receiving means can restore the transmission data from the transmission medium based on the identification information and information in sequence added to the data segments. In this way, it is possible to carry out the transmission / reception processing of several data segments formed by dividing the transmission data corresponding to the number of types of identification information in a single cycle of data transmission. Therefore, the data can be transmitted high speed. In addition, the information in sequence for the data is added to the data segments, so that the receiving means can restore the original transmission data even in the case where the data segments mentioned above are received in disorder. Also, in accordance with the present invention, the information receiver receives the aforementioned data segments transmitted thereto, when the transmission data is divided into units of transmission data segmentation to obtain data segments.; information is added in sequence to each data segment in the sequence in which it is divided and a plurality of pieces of identification information are also added to each data segment to identify the transmission data, and the data segments are assigned to which adds the different identification information within a single cycle of data transmission. With the restoration of the transmission data from the transmission medium based on the identification information and the information in sequence added to the data segments, it is possible to receive several data segments formed by dividing the transmission data corresponding to the number of data transmitted. types of identification information in a single cycle of data transmission. Therefore, the data can be transmitted at high speed. Also, the information in sequence for the data is added to the data segments, so that the receiving means can restore the original transmission data even in the case where the aforementioned data segments are received in disorder. By the present invention, by adding identification numbers of information and information in sequence to the transmitted data segments, it can be confirmed that the order of the data segments within the original data is the same as in the original data. Therefore, the original data can easily be recreated from the data segments. Furthermore, even in the case where the specific data is divided by adding different types of information identification numbers to these data segments, they can be transmitted in the same transmission cycle in order to achieve high-speed transmission.
