Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method, program product, device and storage medium. Background Art

[0002] Since the capabilities of terminals in passive IoT scenarios are relatively weak and they generally provide response feedback, the access process of terminals in passive IoT scenarios is different from that of ordinary terminals. Terminals cannot actively report, but access by feeding back random numbers.

[0003] In the passive IoT scenario, the terminal needs to complete multiple interactions with the base station side device to successfully access.

[0045] 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.

[0046] 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.

[0047] In order to facilitate a clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and order of execution.

[0048] 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.

[0049] In addition, in the passive IoT scenario, the terminal needs to complete multiple interactions with the base station side device to successfully access. However, since the terminal cannot determine whether it has successfully accessed, it may still perform the access process after successfully accessing, which will reduce the processing efficiency of the terminal.

[0050] In view of the above problems, the present application provides a communication method, including: a network device can receive a second feedback message from a first terminal. The second feedback message is a message that the terminal reports a fixed identifier to the network device during a random access process. The first terminal is a terminal that successfully reports a fixed identifier. Afterwards, the network device can send a third indication message to the first terminal. The third indication message is used to indicate that the first terminal does not receive the first indication message. The first indication message is used to indicate that the terminal reports a temporary identifier during a random access process.

[0051] As can be seen from the above, after receiving the first feedback message sent by the first terminal, the network device can determine that the first terminal has successfully accessed. Afterwards, the network device can send a third indication message to the terminal to indicate that the first terminal does not need to receive the first indication message. Since the first indication message is used for the terminal to report a temporary identifier during the random access process, the first terminal does not need to re-report the temporary identifier during the random access process, that is, there is no need to start a new access process. In this way, the terminal can determine that its access is successful based on the third indication message, and no longer receive the first indication message for access, thereby avoiding the terminal from re-accessing after successful access, and further reducing the terminal's operations and improving the terminal's processing efficiency.

[0052] 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.

[0053] 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.

[0054] In the present application, the terminal 102 may send a second feedback message to the network device 101. Afterwards, the network device 101 may receive the second feedback message from the terminal 102 and send a third indication message to the terminal 102. The terminal 102 may receive the third indication message sent by the network device 101 and determine that it has successfully accessed without receiving the first indication message for access, thereby avoiding re-access after successful access.

[0055] 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).

[0056] 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.

[0057] 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.

[0058] The basic hardware structure of the network device 101 and the terminal 102 includes Figure 2 The communication device shown in FIG. Figure 2 Taking the communication device shown as an example, the hardware structure of the network device 101 and the terminal 102 is introduced.

[0059] 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.

[0060] 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.

[0061] As an embodiment, the processor 21 may include one or more CPUs, such as Figure 2 CPU 0 and CPU 1 are shown in .

[0062] 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.

[0063] 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.

[0064] 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.

[0065] In another possible implementation, the memory 22 may also be integrated with the processor 21 .

[0066] 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.

[0067] 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.

[0068] 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.

[0069] The communication method provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0070] 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:

[0071] S301. The terminal sends a second feedback message to the network device.

[0072] The second feedback message is a message in which the terminal reports a fixed identifier to the network device during the random access process.

[0073] S302: The network device receives a second feedback message from the first terminal.

[0074] The first terminal is a terminal that successfully reports the fixed identification. Optionally, the fixed identification is related to the physical device of the terminal, is unique, and can be an electronic product code (EPC).

[0075] During the random access process, the terminal needs to first report a temporary identifier to the network device, and then report a fixed identifier to the network device. If the fixed identifier is successfully reported, the network device determines that the terminal has been successfully accessed. In this case, the network device can receive the second feedback message sent by the first terminal, and can determine that the first terminal that sent the second feedback message is a terminal that has successfully accessed based on the fixed identifier in the second feedback message.

[0076] S303. The network device sends a third indication message to the first terminal.

[0077] The third indication message is used to instruct the first terminal not to receive the first indication message. The first indication message is used to instruct the terminal to report a temporary identifier during a random access process.

[0078] During the random access process, since the terminal in the passive IoT scenario requires the network device to initiate an access indication, the network device sends a first indication message to the terminal during the random access process so that the terminal can start the access process. In this case, after determining that the first terminal has successfully accessed, the network device can send a third indication message to the first terminal, and through the third indication message, indicate that the first terminal does not need to receive the first indication message, that is, does not need to re-access, thereby avoiding the terminal from re-accessing after successful access, further reducing the terminal's operations, and improving the terminal's processing efficiency.

[0079] S304: The terminal receives a third indication message from the network device.

[0080] After receiving the third indication message, the terminal can determine that its access is successful and will not receive the first indication message again, that is, will not access again.

[0081] In a possible implementation, the third indication message may include a fixed identifier of the first terminal. In this way, the terminal receives the third indication message and can determine that its report is successful based on the fixed identifier therein, thereby not needing to receive the first indication message again.

[0082] In yet another possible implementation, the third indication message may also be used to instruct the terminals that have failed to report the fixed identifier to re-receive the first indication message, so that the access procedures of these terminals are rolled back to the initial state.

[0083] In some embodiments, Figure 4 A schematic diagram showing a communication method Figure 2 . Combined Figure 3 ,like Figure 4 As shown, before the above S301, the method provided in the embodiment of the present application further includes:

[0084] S401. A network device determines a priority order of at least one terminal based on first feedback information of at least one terminal.

[0085] After the network device receives the first feedback message sent by at least one terminal, the terminal that successfully sent the temporary identification can be prioritized according to the first feedback message received within a preset time period (for example, sorted according to the order in which the first feedback message is received). In addition, the network device can also determine the random code that matches each temporary identification and determine the unique channel between each terminal and the network device. Optionally, these terminals that establish channels are marked as successful reporting terminals in the network device.

[0086] S402: The network device sends a second indication message to at least one terminal in sequence based on a priority order of the at least one terminal.

[0087] The second instruction message is used to instruct the terminal to report a fixed identifier.

[0088] Before the terminal sends the second feedback message, the network device needs to send a second indication message to the terminal to instruct the terminal to report a fixed identifier, thereby completing the access process. In addition, when the network device sends the second indication message to the terminal, it can also send it in sequence based on the priority of at least one terminal. For example, the one with a higher priority is sent earlier. Accordingly, at least one terminal receives the second indication message at different time points, and sends the second feedback message at different time points. In this way, the multiple second feedback messages sent by at least one terminal do not overlap in the time domain, thereby avoiding collisions between the second feedback messages, improving the access success rate, and further improving the utilization of transmission resources.

[0089] It should be noted that when the terminal reports the second feedback message, the reporting may fail due to environmental factors (such as interference, fluctuation, clock jitter, etc.). Therefore, the terminal cannot determine whether the second feedback message it sends is sent successfully.

[0090] In some embodiments, Figure 5 A schematic diagram of a process for reporting a temporary identifier is shown. Figure 4 ,like Figure 5 As shown, before the above S401, the method provided in the embodiment of the present application further includes:

[0091] S501. A network device sends a first indication message.

[0092] The first indication message is used to instruct the terminal to report the temporary identifier. Optionally, the first indication message may also be used to instruct the terminal to report the first candidate resource used for the temporary identifier. The first candidate resource may include multiple resource blocks, and the multiple resource blocks include spectrum resources and / or time slot resources.

[0093] 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.

[0094] Since the processing and communication capabilities of passive IoT terminals are relatively weak, when accessing a network device, the network device needs to initiate the access. Therefore, the network device can send a first indication message to the terminal to instruct the terminal to report a temporary identifier, thereby starting the random access process of the terminal.

[0095] In addition, before the network device sends the first indication message, the network device may also send other command information to control the marked terminal. Other command information may be clearing terminal information so that the terminal no longer responds, modifying the content in the terminal memory, etc.

[0096] S502: The terminal receives a first indication message from a network device, and sends a first feedback message to the network device.

[0097] The first feedback message is used to indicate a temporary identifier of the terminal.

[0098] 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.

[0099] S503: The network device receives a first feedback message from the third terminal.

[0100] Among them, the third terminal is the terminal that successfully reports the first feedback message.

[0101] When reporting the first feedback message, the terminal may fail to report the first feedback message due to conflicts or environmental factors. Therefore, the network device cannot receive the first feedback messages sent by all terminals, and can only receive the first feedback message sent by the third terminal that has successfully reported. After that, the network device only sends the second indication information to the third terminal, and those terminals that failed to report the first feedback message do not participate in the subsequent process of the current round of random access process, and wait for access in the next round of random access process. In this way, multiple terminals can transmit the information of feedback temporary identifier and feedback fixed identifier separately, that is, when transmitting the first feedback message, no terminal transmits the second feedback message, thereby reducing the probability of resource collision, improving resource utilization, and further improving the access success rate.

[0102] In one possible implementation, the network device may clear the temporary identifier reported by the second terminal. The second terminal is a terminal that failed to successfully report a fixed identifier. Because the network device receives the temporary identifier reported by the third terminal and stores the temporary identifier corresponding to the third terminal. However, when receiving the second feedback message, the network device may not be able to receive the fixed identifiers corresponding to all third terminals, and may only receive the fixed identifiers corresponding to some of the third terminals. In this case, the network device may clear the temporary identifier of the second terminal that successfully reports the temporary identifier and fails to report the fixed identifier, so that the second terminal can wait again for the next round of random access process.

[0103] Figure 6A schematic diagram of a random access process is shown. Exemplarily, the network device can send a first indication message to the terminal 1, the terminal 2, and the terminal 3 can all receive the first indication message. Afterwards, in time slot 1 (i.e., the time slot reported normally), the terminal 2 reports the first feedback message (also referred to as the access code) to the network device, and the network device successfully receives the first feedback message from the terminal 2, i.e., the time slot 1 is a normal time slot. In time slot 2, no terminal reports the first feedback message, i.e., the time slot 2 is an empty time slot. In time slot 3, the terminal 1 and the terminal 3 report the first feedback message through the same transmission resource (i.e., the same time slot). Due to the existence of resource conflicts, the network device fails to successfully receive the first feedback messages of the terminal 1 and the terminal 3, i.e., the time slot 3 is a contention time slot. Then, the network device can send a second indication message to the terminal 2. After receiving the second indication message, the terminal 2 can send a second feedback message to the network device. After the second feedback message is successfully reported, the network device can send a third indication message to the terminal 2 to indicate that the terminal 2 does not need to receive the first indication message of the subsequent round. Subsequently, the device may send the first indication message again in the next round of random access process, and the terminal 2 no longer receives the first indication message.

[0104] It should be noted that the first indication message sent by the terminal occupies a time slot alone, and the reporting time slot of the terminal is determined by the first indication message, and other terminals select a time slot to report the first feedback message.
