[0052] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0053] It should be noted that, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0054] In order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second", etc. are used to distinguish the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second", etc. are not limiting the quantity and execution order.

[0055] Passive Internet of Things (P-IoT), also known as ambient Internet of Things (A-IoT), is a network communication technology based on passive terminals. Passive terminals are usually devices that do not require built-in batteries and are not powered by external power cords. Such devices can obtain energy in other ways to ensure their normal operation. In the process of studying passive Internet of Things, it is necessary to consider the method of terminal access to the network. At present, the terminal access network is similar to radio frequency identification (RFID) technology. It can feedback random numbers through algorithms such as aloha and Q-selection to determine the channel for access. It is a complete time-division system. Among them, since the process of reporting random numbers occurs randomly, there will be channel conflict interference that reduces the recognition speed of the terminal.

[0056] In addition, in the scenario of passive Internet of Things, the base station side device can allow multiple terminals to access through multiple rounds of random access processes. In each round of random access process, the base station side device needs to allocate transmission resources to the terminal so that the terminal can access based on the allocated transmission resources. However, when the terminal accesses the base station side device, it may access the wrong base station side device. This will lead to various problems such as data insecurity. Therefore, how to prevent the terminal from accessing the wrong base station side device is an urgent problem to be solved.

[0057] In view of the above problems, the present application provides a communication method, including: a terminal can receive a first indication message sent by a network device, the first indication message is used to instruct the terminal to report a temporary identifier during a random access process. Afterwards, the terminal can send a first feedback message to the network device when it is determined that the network device authentication is successful, the first feedback message is used to report the temporary identifier of the terminal.

[0058] As can be seen from the above, the terminal can receive the first indication message sent by the network device, and after determining that the network device authentication is successful, the terminal can determine that the network device is the correct network device, and send a first feedback message to the network device, thereby starting the access process with the network device. In this way, the terminal can access the network device only after determining that the network device authentication is successful, thereby preventing the terminal from accessing the wrong network device.

[0059] The communication method is applicable to a communication system. Figure 1 A structure of the communication system is shown. Figure 1 As shown, the communication system includes: a network device 101 and a terminal 102.

[0060] The network device 101 is connected to the terminal 102 for communication. The network device 101 may be a reader / writer, a base station, an access network device, etc. The terminal 102 may be an Internet of Things device, a passive Internet of Things device, a label, an electronic price tag, etc.

[0061] In the present application, the network device 101 may send a first indication message to the terminal 102. Accordingly, after receiving the first indication message, the terminal 102 may authenticate the network device, and if the authentication is successful, the terminal 102 may send a first feedback message for reporting a temporary identifier to the network device 101 to access the network device 101.

[0062] Optionally, the terminal may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing device connected to a wireless modem. The terminal may communicate with one or more core networks via a radio access network (RAN). The terminal may be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, or a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with a radio access network, such as a mobile phone, a tablet computer, a laptop computer, a netbook, a personal digital assistant (PDA).

[0063] The above-mentioned passive IoT devices can be wearable devices (such as smart watches, smart bracelets, pedometers, etc.), vehicle-mounted devices (such as passive communication accessories in cars, bicycles, electric vehicles, airplanes, ships, trains, high-speed railways, etc.), virtual reality (VR) devices, augmented reality (AR) devices, passive IoT devices in industrial control, smart home devices (such as refrigerators, televisions, air conditioners, electric meters, sensor devices in shelf price tags, etc.), intelligent robots, workshop equipment, wireless terminals in self-driving, passive IoT devices in remote medical surgery, passive IoT devices in smart grids, passive IoT devices in transportation safety, passive IoT devices in smart cities, or passive IoT devices in smart homes, etc.

[0064] The above-mentioned base station can be a base station or base station controller for wireless communication, etc. In the embodiment of the present application, the base station can be a base station (base transceiver station, BTS) in the global system for mobile communication (global system for mobile communication, GSM), code division multiple access (code division multiple access, CDMA), a base station (node ​​B) in wideband code division multiple access (wideband code division multiple access, WCDMA), a base station (eNB) in the Internet of Things (Internet of Things, IoT) or narrowband Internet of Things (narrow band-internet of things, NB-IoT), a base station in the future 5G mobile communication network or the future evolved public land mobile network (publicland mobile network, PLMN), and the embodiment of the present application does not impose any restrictions on this.

[0065] The basic hardware structure of the network device 101 and the terminal 102 includes Figure 2 The components included in the communication device shown are described below. Figure 2 Taking the communication device shown as an example, the hardware structure of the network device 101 and the terminal 102 is introduced.

[0066] like Figure 2, which is a schematic diagram of a hardware structure of a communication device provided in an embodiment of the present application. The communication device includes a processor 21, a memory 22, a communication interface 23, and a bus 24. The processor 21, the memory 22, and the communication interface 23 can be connected via a bus 24.

[0067] The processor 21 is the control center of the communication device, which can be a processor or a general term for multiple processing elements. For example, the processor 21 can be a general-purpose central processing unit (CPU) or other general-purpose processors. Among them, the general-purpose processor can be a microprocessor or any conventional processor.

[0068] As an embodiment, the processor 21 may include one or more CPUs, such as Figure 2 CPU 0 and CPU 1 are shown in .

[0069] The memory 22 may be a read-only memory (ROM) or other type of static storage device that can store static information and instructions, a random access memory (RAM) or other type of dynamic storage device that can store information and instructions, an electrically erasable programmable read-only memory (EEPROM), a disk storage medium or other magnetic storage device, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited thereto.

[0070] In a possible implementation, the memory 22 may exist independently of the processor 21, and the memory 22 may be connected to the processor 21 via a bus 24 to store instructions or program codes. When the processor 21 calls and executes the instructions or program codes stored in the memory 22, the communication method provided in the following embodiments of the present application can be implemented.

[0071] In the embodiment of the present application, for the network device 101 and the terminal 102, the software programs stored in the memory 22 are different, so the network device 101 and the terminal 102 implement different functions. The functions performed by each device will be described in conjunction with the following flowchart.

[0072] In another possible implementation, the memory 22 may also be integrated with the processor 21 .

[0073] The communication interface 23 is used for the communication device to connect with other devices through a communication network, and the communication network may be Ethernet, wireless access network, wireless local area network (WLAN), etc. The communication interface 23 may include a receiving unit for receiving data and a sending unit for sending data.

[0074] The bus 24 may be an industry standard architecture (ISA) bus, a peripheral component interconnect (PCI) bus, or an extended industry standard architecture (EISA) bus. The bus may be divided into an address bus, a data bus, a control bus, etc. For ease of representation, Figure 2 Only one thick line is used in the diagram, but this does not mean that there is only one bus or only one type of bus.

[0075] It should be pointed out that Figure 2 The structure shown in the figure does not constitute a limitation on the communication device, except Figure 2 In addition to the components shown, the communication device may include more or fewer components than shown, or combine certain components, or arrange the components differently.

[0076] The communication method provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0077] The communication method provided in the embodiment of the present application is applied to Figure 1 The network device 101 and the terminal 102 in the communication system shown in FIG. Figure 3 As shown, the communication method provided in the embodiment of the present application includes:

[0078] S301. A terminal receives a first indication message sent by a network device.

[0079] The first indication message is used to instruct the terminal to report a temporary identifier during the random access process.

[0080] It should be noted that, since the terminal has not yet accessed the network device, the first indication message sent by the network device is broadcast.

[0081] Since the processing power and communication capability of the terminal in the passive IoT scenario are relatively weak, when accessing the network device, the network device needs to initiate the access. Therefore, the network device can send a first indication message to the terminal, and instruct the terminal to report a temporary identifier through the first indication message to achieve the access of the terminal. Optionally, the first indication message may include the authentication information of the network device itself, and the authentication information is unique, such as the identifier of the network device.

[0082] In a possible implementation, the first indication message is also used to indicate that the terminal reports multiple candidate resources for the first feedback message. The multiple candidate resources may be multiple resource blocks, including time domain resources, and / or frequency domain resources. After receiving the first indication message, the terminal may select a first candidate resource for sending the first feedback message from multiple candidate resources. In addition, since the terminal selects the first candidate resource randomly, different terminals may select the same candidate resource, resulting in a resource collision (or conflict), causing a failure to send the first feedback message.

[0083] S302: When it is determined that the network device authentication is successful, the terminal sends a first feedback message to the network device.

[0084] The first feedback message is used to indicate a temporary identifier of the terminal.

[0085] After receiving the first indication message, the terminal can authenticate the network device to determine whether the network device that sent the first indication message is the correct network device. In the case where the network device authentication is successful, the terminal can determine that the network device is the correct network device, and in response to the first indication message, send a first feedback message for reporting a temporary identifier to the network device, thereby implementing a subsequent access process. In this way, since the terminal will send the first feedback message for access only after the authentication is successful, and will not send the first feedback message after the authentication fails, the terminal can avoid accessing the wrong base station.

[0086] In a possible implementation, the temporary identifier may be a set of random numbers determined by the first terminal (generated by itself or selected from multiple random numbers), and the number of information bits of the random number is as small as possible, thereby reducing the possibility of collision (or conflict) when reporting the random number. It should be understood that the fewer the number of information bits of the random number, the fewer resources used during transmission, and the smaller the probability of conflict with resources used by other first terminals to transmit random numbers.

[0087] In some embodiments, the first indication message is also used to indicate authentication information of the network device.

[0088] Optionally, the authentication information may include at least one of the following: a network device identifier, a cell identifier, or a media access control (MAC) address.

[0089] In another possible implementation, the terminal may pre-store the authentication information of all correct base stations and form a target authentication information set. When the authentication information belongs to the target authentication information set, the terminal determines that the authentication information is successfully identified. In this way, after receiving the authentication information, the terminal can determine whether the authentication information belongs to the target authentication information set. When it is determined that the authentication information belongs to the target authentication information set, the terminal determines that the authentication information is successfully identified. On the contrary, when it does not belong to the target authentication information set, the terminal can determine that the authentication information is unsuccessful to identify.

[0090] In some embodiments, Figure 4 A schematic diagram showing a communication process Figure 2 . Combined Figure 3 ,like Figure 4 As shown, the method provided in the embodiment of the present application also includes:

[0091] S401. A network device receives a first feedback message and sends a second indication message to a terminal.

[0092] The second indication message is used to instruct the terminal to report a fixed identifier during the random access process.

[0093] The network device receives the first feedback message reported to the terminal, and determines the temporary identifier in each first feedback message. Afterwards, the network device can generate a random code corresponding to each temporary identifier, and determine that the terminals that successfully report the first feedback message are successfully reported terminals. Afterwards, the network device can send a second indication message to these successfully reported terminals to instruct these terminals to report their own fixed identifiers. Optionally, the fixed identifier is related to the terminal physical device, is unique, and can be an electronic product code (EPC).

[0094] S402: The terminal receives a second indication message, and sends a second feedback message to the network device.

[0095] The second feedback message is used to indicate a fixed identifier of the terminal.

[0096] After the terminal receives the second indication message sent by the network device, it can determine that it has successfully fed back the temporary identifier according to the temporary identifier in the second indication message. After that, the terminal can respond to the second indication message and send a second feedback message to the network device, thereby feeding back its fixed identifier to the network device. After the network device receives the second indication message sent by the terminal, it can successfully access the terminal.

[0097] The above is a description of the access process of a terminal to a network device. The following will describe the process after the terminal fails in authentication.

[0098] In some embodiments, Figure 5 A schematic diagram of a process for identifying failure is shown. Figure 3 ,like Figure 5 As shown, the method provided in the embodiment of the present application also includes:

[0099] S501. When network device authentication fails, the terminal sends an abnormality indication message to the target network device.

[0100] The target network device is a network device that has been successfully connected, and the abnormal indication message is used to indicate the access indication of the network device that has failed authentication.

[0101] In the case of network device authentication failure, the terminal can determine that the sending network device is an incorrect network device, and the terminal does not perform subsequent access operations. Afterwards, when the terminal successfully accesses the correct target network device, the terminal can send an abnormal indication message to the target network device, thereby informing the target network device through the abnormal indication message that the terminal has received an access indication of the network device that failed authentication. After receiving the abnormal indication message, the target network device can determine that the terminal has received an abnormal access according to the message.

[0102] In a possible implementation, the first message includes at least one of: an abnormality indication codeword and authentication information of authentication failure, and the abnormality indication codeword is used to indicate that the terminal has received an access indication of a network device of authentication failure.

[0103] After determining that the authentication information recognition fails, the terminal can modify the value of the codeword stored in itself to a preset value, and when the codeword is determined to be the preset value, the terminal can determine that its state is an alarm state. After accessing the target network device, the terminal can send the codeword to the target network device through a first message, so that the target network device determines that the terminal has received an access instruction from an erroneous base station, so that the staff can maintain the access process between the terminal and the network device to ensure the data security of the terminal.

[0104] Alternatively, after determining that the authentication information fails to be authenticated, the terminal may store the authentication information. Afterwards, after the terminal accesses the target network device, the terminal may send the authentication information to the target network device through a first message, so that the target network device can record the authentication information that failed to be identified, thereby preventing other terminals from accessing the network device. Optionally, for authentication information that fails to be authenticated, the target network device may establish a failed authentication information set and synchronize the authentication information set to all terminals to prevent other terminals from accessing the network device to which the authentication information belongs.

[0105] It should be understood that the terminal can have an information storage function to store the target authentication information set, and can also have a comparison module for executing different instructions after the authentication information is successfully or failed, such as sending a first feedback message to the network device when the authentication information is successfully identified, and not accessing when the authentication information fails.

[0106] The above mainly introduces the solution provided by the embodiment of the present application from the perspective of the method. In order to realize the above functions, it includes hardware structures and / or software modules corresponding to the execution of each function. Those skilled in the art should easily realize that, in combination with the units and algorithm steps of each example described in the embodiments disclosed herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the present application.

[0107] The embodiment of the present application can divide the functional modules of the communication device according to the above method example. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The above integrated module can be implemented in the form of hardware or in the form of software functional modules. Optionally, the division of modules in the embodiment of the present application is schematic and is only a logical function division. There may be other division methods in actual implementation.
