Because the processing of the protocol conversion method in the related art is complicated, how to design a simple and efficient protocol conversion method is a major problem in the design and application of the Internet of Things gateway. Based on this, the embodiment of the present invention provides a Method and Apparatus for Transmitting Data or Signaling The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

This embodiment provides a method for transmitting data or signaling, which may be implemented on the device side. FIG. 1 is a flowchart of a method for transmitting data or signaling according to an embodiment of the present invention. The method includes the following steps:

Step S102: The main processor receives data or signaling of the current sub-processor, and the data or the letter Convert data or signaling to an intermediate format;

Step S104: The main processor processes the data or signaling of the intermediate format to obtain data or signaling result in an intermediate format; and converts the data or signaling result of the intermediate format into target data or signaling; wherein, the foregoing target The data or signaling follows the target protocol of the target sub-processor; Step S106: The main processor sends the above-mentioned target data or signaling to the target sub-processor. Through the above method, the complex processing problem of the protocol conversion method in the related art is solved, thereby quickly and simply implementing data or signaling conversion between the sensing network and the traditional communication network, and various sensing networks, and the conversion is performed by means of A unified intermediate format to mask data or signaling formats from different sensing networks and traditional communication networks with low processing complexity and good scalability.

In order to implement the data or signaling conversion between the sensing network and the traditional communication network in a simple and efficient manner, the current sub-processor in this embodiment may be a downward sub-processor, and the target sub-processing

Alternatively, the current sub-processor is an up sub-processor, and the target sub-processor is a down sub-processor.

In order to implement data or signaling conversion between various sensing networks in a simple and efficient manner, both the current sub-processor and the target sub-processor in this embodiment may be a downward sub-processor.

The downward sub-processor is a processor that interacts with various perceptual layer network nodes. Due to the diversity of the layer of the layer, the gateway may have multiple down sub-processors, such as a radio frequency processor in communication with the wireless sensor network, an RFID receiver processor in communication with the RFID node, and the like.

The up sub-processor is a processor that connects the gateway up to the Internet (Internet) or the mobile communication network.

The connection mode of the uplink connection may be a wired network such as xDSL (xDSL is a general term for various types of digital subscriber lines (DSL)), or may be 2G network general packet radio service (GPRS), 3G network, 4th generation mobile communication technology (4th generation, 4G) network, Wi-Fi and other wireless networks.

The gateway should configure one or more upward sub-processors corresponding to the foregoing network according to the network provision situation of the application and the upward transmission traffic. For example, an Ethernet controller connected to the Internet, a GPRS module connected to the mobile communication network, and the like.

The main processor in this embodiment is configured to complete conversion between two types of protocols supported by the upper sub-processor and the lower sub-processor, and the protocol conversion is mainly divided into two aspects: data conversion and signaling conversion. Protocol conversion refers to converting one party's data or signaling format into a data or signaling format that the other party can recognize, and transmitting it to the other party completely and correctly.

The above three layers of processors (the main processor, the down processor, and the up processor) exchange information through two types of interfaces: a class A interface and a class B interface. The following describes the Type A interface and the Type B interface.

Class A interface refers to the communication interface between the main processor and the lower sub-processor. Class A interfaces should have two characteristics:

(1) The interface should have versatility and standardity, including hardware and communication protocols, that is, various down-sub-processors can communicate with the main processor through this unified interface, and each sub-processor can Direct communication or indirect communication through the host processor;

(2) The interface should be extensible. For example, a gateway with only sub-processor a can be externally connected with a module with sub-processor b, so that the gateway can allow access to the sensing network supported by sub-processor b. Thereby expanding the cognitive access capability of the gateway. Assuming that the module with sub-processor b is called an expansion module, such an expansion module can still communicate with the main processor through the above-mentioned class A interface.

Therefore, the class A interface is actually a multi-processor or multi-chip communication interface. The communication mode generally adopted is serial communication, and a main multi-slave string is performed between the main processor and the down sub-processor. Line communication, communication speed / baud rate is defined by the user or a standard organization. In addition, there is an application requirement that the above expansion module can be directly connected to the computer, and the two together complete the function of the IoT gateway (ie, the computer acts as the gateway's main processor and the upper sub-processor, and upwardly accesses

The Internet is Ethernet or Wi-Fi, so the expansion module should have a USB interface. Therefore, the Type A interface can be considered to use a USB interface, or the Type A interface can be converted to a USB interface in some way.

Class B interface refers to the communication interface between the main processor and the upper sub-processor. This type of interface technology is relatively mature at present, and there are many types of interfaces. For example, if the gateway uses xDSL wired connection to the Internet, the upper sub-processor may be an Ethernet controller, and the interface between the main processor and the Ethernet controller may adopt a high-speed bus mode (including data lines and address lines). , control line), you can also use low-speed and low-line serial communication (send line, receive line, control line). If the gateway uses GPRS to access the Internet, the upper sub-processor is a GPRS module/processor, and the interface between the main processor and the GPRS module/processor is mostly serial communication. If the gateway uses Wi-Fi to access the Internet, the upper sub-processor is a Wi-Fi module/processor, and the interface between the main processor and the Wi-Fi module/processor can be either a bus or a serial. way of communication.

Based on the foregoing description of the class A interface and the class B interface, this embodiment provides a preferred implementation manner for improving the utility and application scope of the data or signaling transmission method. That is, the main processor performs data or signaling interaction with the lower sub-processor through the first interface (ie, the above-mentioned type A interface); the main processor performs data or data with the upper sub-processor through the second interface (ie, the above-mentioned type B interface) Signaling interaction; wherein, the first interface is a serial communication interface or a USB interface; and the second interface is a serial communication interface or a bus interface.

As shown in FIG. 2, the hardware related to the protocol conversion function on the gateway mainly includes: a main processor, a downward sub-processor, and an upward sub-processor; among them, The main processor and the lower sub-processor perform data or signaling interaction through a class A interface;

The main processor and the upper sub-processor perform data or signaling interaction through a class B interface.

For the data or signaling sending method introduced in this embodiment, the main purpose is to convert the data or signaling conforming to the protocol of the current sub-processor, convert it into intermediate format data or signaling, and then convert the protocol. Converting intermediate formatted data or signaling into data or signaling that follows the target sub-processor protocol. In short, the data or signaling format of one party is converted into a data or signaling format that the other party can recognize.

FIG. 3 is a schematic diagram of a software main body architecture of a multi-protocol gateway according to an embodiment of the present invention. As shown in FIG. 3, there are three software main bodies related to protocol conversion on the gateway: A series protocol, B series protocol, and intermediate format. In addition, there are two processes of protocol conversion 1 and protocol conversion 2 between the A series protocol and the B series protocol and the intermediate format respectively.

The A-series protocol refers to the perceptual layer network protocol running/loading on the lower sub-processor, such as the ZigBee protocol of the wireless sensor network or other custom protocols.

The B-series protocol refers to the traditional communication network protocol that runs/loads on the upper sub-processor, such as the Ethernet protocol stack on the Ethernet controller and the GPRS protocol stack on the GSM module.

The intermediate format refers to a standard signaling format and data format that is run/loaded on the host processor. Before the signaling and data interaction between the A series protocol and the B series protocol, the standard signaling is converted to the standard signaling. Format and data format. This conversion process is the protocol conversion 1 and protocol conversion 2 shown in Figure 3. The implementer of protocol conversion 1 and protocol conversion 2 is the main processor in the gateway.

Protocol conversion 1, refers to the process of the main processor converting the data or signaling into an intermediate format when each of the downstream sub-processors sends data or signaling conforming to the A-series protocol to the main processor through the class A interface. And the reverse of the process.

Protocol conversion 2, when each of the upper sub-processors will follow the data of the B-series protocol or The process by which the primary processor translates the data or signaling into an intermediate format when the signaling is sent to the primary processor through the class B interface, and the reverse of the process.

In this embodiment, the main processor includes: a protocol processing module configured to convert data or signaling into data or signaling in an intermediate format, and the reverse process of the process.

Preferably, the protocol processing module includes: a data processing unit or a signaling processing unit, where the two units respectively perform a conversion operation on data or signaling.

As shown in FIG. 4, three A series protocols are listed in FIG. 4: Al, A2, A3, and three B series protocols Bl, B2, and B3. The conversion between the protocol Al and the intermediate format is now described as an example. When the data or signaling of the protocol A1 reaches the main processor through the class A interface, the main processor analyzes the protocol type of the data or signaling, and then transfers the data or signaling to the protocol processing module TA1 according to the protocol type, and the protocol processing module TA1 The data or signaling is converted to data or signaling in an intermediate format.

Then, the main processor processes the data or signaling in the intermediate format to obtain the data or signaling result in the intermediate format, and the main processor determines the protocol type of the target sub-processor (assumed to be the protocol B1), and corresponds to the protocol type. The protocol processing module TBI converts the data or signaling results of the intermediate format into data or signaling that conforms to protocol B1.

Similarly, the processing manners of the protocol A2 and the protocol A3 are the same as those of the protocol A1 described above, and are not described here.

Based on the protocol conversion process introduced in FIG. 4 above, this embodiment provides a preferred implementation manner, that is, the main processor converts data or signaling into intermediate format data or signaling, including: the main processor determines the current sub-processor.
