TH32406B - Methods and devices for issuing cross-region commands to data communication receivers. - Google Patents

Abstract

The DC60 communication system (105) provides roaming commands on signals containing data frames. The communication system (105) consists of a transmitting device (110) for organizing messages into data frames and transmitting them over a radio channel within a predefined geographic area. A frame contains at least a frame offset message which a data receiver (115) located within the predefined geographic area will receive. The data receiver (115) stores the base frame number associated with the base frame to which the data receiver (115) is assigned to wake up for the message. The frame offset message identifies the substitute frame associated with the base frame. The data receiver (115) then wakes up for the message in the substitute frame instead of the base frame. The communication system (105) provides roaming commands on signals containing data frames. The communication system (105) consists of a transmitting device (110) for organizing messages into data frames. The frame of information is transmitted over a radio communication channel within a predefined geographic area. The frame shall contain at least a message regarding the frame offset, which a data receiver (115) located within the predefined geographic area will receive. The data receiver (115) shall store the base frame number associated with the base frame to which the data receiver (115) is assigned to wake up to receive the message. The message regarding the frame offset shall specify the alternate frame associated with the base frame. The data receiver (115) shall then wake up to receive the message in the alternate frame that will be the base frame.

Claims (20)

1. The method in a communication system for sending signals containing cross-region commands to a receiver: In data communication, the signal consists of data frames. The data communication receiver has memory for storing the base frame number, which is associated with the base frame. While the data communication receiver is awake to receive the message, the method involves the following steps: arranging the message into a data frame, where the frame contains information about the frame offset for reception by the data communication receiver; the frame offset information specifies the alternative frame relative to the base frame and its location within the signal received by the data communication receiver; the receiver then awakens to receive the message in that alternative frame instead of the base frame; and transmitting the message over a radio communication channel within a predefined geographical area. 2. The method under Claim 1, whereby the encoding and transmission procedures are performed in the transmitting device integrated into the communication system, and whereby that method, in the transmitting device, further includes the following procedures: determining whether the data communication receiver is operating across zones, and encoding and transmitting the message for the data communication receiver in that alternative frame instead of the base frame. 3. The method under claim 2, which continues, in the data communication receiver, involves the following steps: receiving the frame offset message, where the frame offset message contains a value; calculating the replacement frame number by adding that value to the base frame number; the replacement frame number is associated with the replacement frame; and storing that replacement frame number. 4. The procedure under claim 3, which continues, in the data communication receiver, involves the following steps: granting permission for the receiving circuit integrated into the data communication receiver to receive the currently transmitted data frame; following the retrieval step, assigning an associated number to the currently transmitted frame; receiving the information contained in the currently transmitted frame when the data frame number equals the replacement frame number; and closing the receiving circuit when the frame number does not equal the replacement frame number. 5. The method under Claim 2, which is further incorporated, in the messaging device, involves the following steps: receiving the message for transmission to the data communication receiver that has been determined to be the local data communication receiver, and assembling and transmitting the message to the local data communication receiver within the framework assigned to that local data communication receiver. 6. A communication system for providing cross-region operation commands in signals, comprising a filter of various data frames. The communication system consists of: a messaging device for organizing a series of messages into data frames and transmitting those messages over a radio communication channel within a predefined geographical area. The frame consists of a frame offset message which the cross-region receiver receives, and a data communication receiver within that predefined geographical area for that message. The data communication receiver stores the base frame number associated with the base frame to which the receiver is assigned to wake up to receive the message. The frame offset message specifies the alternative frame relative to the base frame and its location within the signal received by the data communication receiver. The receiver then wakes up to receive the message in that alternative frame instead of the base frame. 7. The communication system under claim number 6, whereby the transmission device shall consist of: - a means of detecting whether the data communication receiver is operating across zones; a set-up unit which is circuit-connected to the detection factor to set-up the message for the data communication receiver into the replacement frame instead of the base frame; and a transmitter unit which is circuit-connected to the set-up unit to transmit the message between replacement frames. 8. The communication system under claim number 7, where information concerning the offset of the constituent frame includes a single value, and where the replacement frame is the same as the number of the replacement frame, which is calculated by adding the value to the number of the basic frame. 9. The communication system under claim number 8, whereby the data communication receiver shall consist of a receiving circuit to receive information about the frame offset; a processing unit which is circuit-connected to the receiving circuit to add that value to the frame number; a basis for calculating the replacement frame number relating to the replacement frame; and a memory unit which is circuit-connected to the processing unit to store the replacement frame number. 10. The communication system under claim 9, whereby the data communication receiver shall include: - a circuit closure method for receiving messages within the replacement frame instead of the basic frame, and a circuit closure method for receiving in other frames besides the replacement frame. 11. The communication system under claim paragraph 6, whereby the signal frames consist of a block message containing information about the frame structure, an address field containing the address of the receiving device, and a message field containing the message intended for the receiving device to receive. 12. The communication system under claim 11, whereby information concerning the selected frame block of the signal includes information concerning the frame offset. 13. A communication system under claim 12 whereby such communication system involves the transmission of a concurrent system identification number (SSID) that is transmitted during a chosen frame. 14. Data Communication Receiver for Receiving Cross-Border Commands. The data communication receiver consists of a receiving circuit to receive signals, which comprise various data frames. The signal contains information about the frame offset. Memory connected to the receiving circuit stores the base frame number, which is associated with the base frame while the data communication receiver is awake to receive messages. A processing unit connected to memory calculates the replacement frame number from the frame offset information. This replacement frame number is associated with the replacement frame whose position is relative to the base frame and is within the signal received by the data communication receiver. The data communication receiver then awakens to receive the message in that replacement frame instead of the base frame. 15. The receiver of data communications under claim 14, whereby information concerning the offset of the frame includes a value, and whereby the replacement frame number is calculated by adding that value to the basic frame number. 16. The receiver of data communications under claim 14, which also includes: - a circuit-opening path for receiving messages between replacement frames in place of the basic frame, and a circuit-closing path for communication between any other frames besides the replacement frame. 17. The receiver of data communications under claim 14, whereby the various signal frames contain a block message which contains information about the frame structure, an address field which contains the address of the receiver to receive, and a message field which contains the message intended for that receiver to receive. 18. A message transmission device is used to provide a signal containing a cross-region command and comprises a number of data frames within a predefined geographic area. The message transmission device includes a memory unit to store frame offset information for distribution to the data receiver; a database to store the numbers of base frames associated with the base frame to which the data receiver is assigned the message; a copier unit circuit-driven to the memory unit to produce the frame offset information as a data frame; and a transmitting unit circuit-driven to the copier unit to transmit the frame containing the frame offset information. This frame offset information specifies the replacement frame that is relative to the data receiver's base frame and is located within the signal range that the data receiver will receive, and which the cross-region receiver will then awaken to receive the message in that replacement frame instead of the cross-region receiver's base frame. 19. A receiver of data communications under claim 18, whereby a number of signal frames containing a block message which contains information about the frame structure, an address field which contains the receiver's address, and a message field which contains the message intended for the receiver to receive. 20. A messaging device pursuant to claim 19 where information concerning the selected block of the signal includes information concerning the offset of the block.
