Definitions
- the present invention relates to a method for addressing an Endge advises z.
- the technical basis of the OMS is the so-called MBus.
- the wireless MBus communication is regulated in more detail in the EN 13757 standard in particular.
- the data are provided by the end devices to the respective gateway in the form of data telegrams.
- the data telegrams in the respective terminal can be divided into individual data packets and transmitted over the primary communication channel.
- the individual data packets are recombined to form the data telegram.
- data telegrams can also be transmitted in full.
- the primary communication channel is a narrow-band channel.
- the data packets or data telegrams of the individual end devices must be transmitted over this channel with as little interference as possible.
- efforts are made to combine as many end devices as possible under one gateway, which in turn has a negative effect on the transmission. Implementing these different goals is therefore difficult.
- the object of the present invention is to further improve the transmission of data from a terminal to a base station in the primary communication channel.
- each gateway of a wireless communication system with primary and tertiary communication preferably a corresponding wireless MBus communication system
- a sub-network is assigned, which consists of the gateway in question and at least one Terminal, preferably a group of terminals is formed, a terminal network address is generated for each terminal assigned to the gateway of the sub-network, and the terminal network address for transmitting data in the primary communication channel between the gateway and the terminals assigned to the latter.
- This terminal network address can be made much shorter in the communication protocol than the “actual address” of the terminal and, according to the invention, serves to transmit data in the primary communication channel between the gateway and the terminals assigned to the latter.
- the length of the primary communication messages can be effectively reduced overall. Nevertheless, the respective end device can be clearly identified in the overall system. Due to the reduced length of the primary communication messages, the channel occupancy can be reduced compared to before. In addition, the range or reception probability can be increased, since the influence of interferers decreases.
- the terminal network address generated by the gateway is used in continuous operation instead of a standardized address of the wireless communication system or the relevant communication protocol.
- the standardized (unique) address of the respective end device e.g. the MBus address, therefore only needs to be used when initializing the overall system.
- the terminal network address is used instead during operation.
- the terminal network address expediently has a smaller number of bytes than the standardized address of the wireless communication system or the relevant communication protocol provided for a terminal.
- the terminal network address is preferably shorter than 8 bytes, that is to say, for example, shorter than the standardized address of the M bus communication protocol, which is 8 bytes.
- the respective terminal network address comprises a primary subnetwork address and a counter address.
- the primary subnetwork address preferably has a length of 1 byte
- the counter address preferably has a length of 2 bytes. Accordingly, the length of the terminal network address is more than half the length of the aforementioned MBus address.
- the respective terminal network address of each terminal preferably includes a gateway address.
- the respective terminal network address of each terminal device expediently comprises a primary network address which is formed by a primary subnetwork address and a counter address.
- the terminal device network address or meter address is only assigned once within a subnetwork of a gateway.
- the terminal network address is expediently generated by the gateway. This can preferably be done the first time the gateway is paired with the terminal in question.
- a tertiary communication channel between the gateway and a head-end or a data center is provided, with an assignment of the data of the individual terminals transmitted to the head-end via the tertiary communication channel in the head-end based on the terminal - Network address is done.
- the head-end i.e. the overall system, is thus able to make an assignment based on the terminal device network address
- a clear assignment can preferably take place in the head-end on the basis of a combination of the gateway address and the primary network address. Alternatively or additionally, an assignment (correlation) can also take place in the gateway. If the gateway knows its primary subnetwork address, it can independently assign primary network addresses to end devices and correlate them.
- the terminal network address can preferably be used in the primary communication channel and preferably also in the tertiary communication channel in both directions, ie in the uplink and downlink.
- FIG. 1 shows a greatly simplified schematic illustration of an example of the addressing concept according to the present invention
- Fig. 2 shows an example of a terminal network address as it is used in the method according to the invention
- Fig. 3 is a greatly simplified schematic representation of another example of the addressing concept according to the present invention, in which a terminal of a subnet is within the range of a gateway of another subnet.
- Fig. 1 shows a communication structure of a generic wireless communication system for wireless communication between terminals 1-1, 1-M, for example permanently installed consumption meters for water, heat, gas or electricity, via a wireless communication system, in particular a wireless MBus communication system Communicate with a head-end 3 via gateways 2-1, 2-N.
- the wireless communication channel between the respective terminal device, for example 1-1, and the associated gateway, for example 2-1, is referred to as primary communication channel 4.
- the communication channel between the respective gateway, for example 2-1, and the head-end 3 is referred to as a tertiary communication channel 5.
- the respective data are provided in the terminals 1-1, 1-M in the form of data telegrams and divided into individual data packets for transmission along the primary communication channel 4.
- the data packets are recombined to form the data telegram after receipt.
- the data telegrams can also be transmitted as such, i.e. in full, to the gateway.
- the primary communication channel 4 is usually a narrowband radio channel.
- the data can be transmitted further from the respective gateway 2-1, 2-N to the head-end 3, for example via WAN (e.g. Internet).
- the headend 3 is operated, for example, by a supplier for water, heat, gas and / or electricity.
- each gateway 2-1, 2-N has its own address (for example MAC address) and each terminal 1-1, 1-M also has a unique, manufacturer-independent address in the communication system.
- a terminal device 1-1, 1-M with OMS has an 8-byte address, due to the so-called M-Field (2 bytes) and A-Field (6 bytes) (EN 13757-4). This address is unique worldwide.
- the respective terminal 1-1, 1-M also retains this (unique) address. However, in the method according to the invention, a further “shorter” address is also assigned, which is then used in primary communication, ie in continuous operation between the relevant gateway, eg 2-1, and the associated terminals 1-1, 1-M, preferably in both directions , is used.
- This is a terminal network address 7-1, 7-M, which is used for each terminal 1-1,1 -M within a subnet 6-1, 6-L of the associated gateway 2-1, 2-N is assigned.
- the terminal device network address 7-1, 7-M is assigned by the gateway z. B. 2-1 of the relevant subnet z. B. 6-1 when pairing the terminal in question z. B. 7-1 with the gateway z. B. 2-1.
- Fig. 2 shows how the terminal network address 7-1, 7-M is designed. It includes a primary subnetwork address PSA, which identifies the respective subnetwork 6-1, 6-L.
- the primary subnetwork address PSA has a length of 1 byte, for example.
- the terminal network address 7-1, 7-M comprises a primary host address PHA, which identifies the relevant terminal 1-1,1 -M within the subnetwork and preferably has a length of 2 bytes.
- the primary host address PHA may only be assigned once within the respective subnetwork 6-1, 6-L.
- the primary sub-network address PSA and the primary host address together form the primary network address PNA, which is, for example, only 3 bytes long, i.e. significantly shorter than the 8-byte (unique) address of the end device in the standard.
- the gateway address uniquely identifies a specific gateway 2-1, 2-N in the overall system.
- a MAC address can be used as a gateway address.
- a combination of gateway address and terminal device network address 7-1, 7-M or primary network address PNA thus uniquely identifies a terminal device in the overall system (primary and tertiary communication).
- Each gateway 2-1, 2-N is thus assigned the respective subnet 6-1, 6-L via the primary subnetwork address PSA.
- PSA primary subnet address does not need to be unique. However, it should be ensured that the subnets are spatially far enough apart so that a meter cannot be in two subnets.
- the address range offers 255 possible subnets, which is more than sufficient for all known fixed networks.
- Each terminal 7-1, 7-M is thus assigned to a gateway, for example 2-1, and thus a fixed network, for example 6-1.
- the gateway 2-1 When the gateway 2-1 is paired with the counter 7-1 for the first time, the gateway assigns the primary host address PHA for the relevant terminal. Together with the primary subnetwork address PSA, the primary network address PNA is formed and assigned to the meter, e.g. 7-1, as a short address. A mapping from wireless MBus to PNA in the gateway is possible at any time.
- the counter 7-M can be received not only by the gateway 2-1 but also by the gateway 2-2.
- the gateway 2-2 forwards the data received from the meter 7-M in the uplink to the head-end 3.
- the headend 3 can correlate the primary network address PNA to the standardized (i.e. unique) counter address of the communication protocol (e.g. M bus address with a length of 8 bytes) on the basis of the known network structure.
- the standardized (i.e. unique) counter address of the communication protocol e.g. M bus address with a length of 8 bytes
- the counter 7-M is within range of the gateway 2-1 and the gateway 2-2.
- the primary network address PNA is thus 1-7777.
- the gateway 2-1 can uniquely identify the counter 7-M at any time using the pairing.
- the gateway 2-2 is not informed about the pairing of the terminal 7-M with the gateway 2-1. However, based on the primary subnetwork address PSA, the gateway 2-2 recognizes that the terminal device 7-M is in a different subnetwork (subnetwork 6-1) than subnetwork 6-2.
- the gateway 2-2 forwards the data or messages from the terminal 7-M to the head-end 3, the head-end 3 recognizes that the primary subnetwork address PSA and the gateway address do not match.
- the primary subnetwork address PSA can then be correlated to the gateway 2-1 through the network structure.
- an assignment can also take place in the gateway 2-1, 2-N. If the gateway 2-1, 2-N knows its primary subnetwork address PSA, it can independently assign primary network addresses PNA to terminals 1-1, 1-M and correlate them. REGARDING SIGN CH EN LI STE
