Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method, device, program product 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] However, when the base station side device processes only some terminals, it cannot obtain the information of all terminals in advance. Therefore, the base station side device needs to select from the information reported by all terminals after accessing all terminals. This will cause a lot of transmission resources to be wasted for those terminals that do not need to access. Summary of the invention

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] In addition, in the scenario of passive Internet of Things, the base station side device can enable 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 base station side device only processes some terminals, it cannot obtain the information of all terminals in advance. Therefore, the base station side device needs to select from the information reported by all terminals after accessing all terminals. In this way, for those terminals that do not need to access, a large amount of transmission resources will be wasted.

[0055] In view of the above problem, the present application provides a communication method, including: a network device may send a first indication message. The first indication message is used to instruct a terminal to report a temporary identifier during a random access process. Afterwards, the network device may receive at least one first feedback message, the first feedback message being used to indicate the temporary identifier of the terminal and attribute information of the terminal.

[0056] As can be seen from the above, after the network device sends the first indication message, the terminal can send a first feedback message to the network, and carry its own attribute information in the first feedback message. In this way, the network device can select the terminal that it needs to process based on the attribute information of multiple terminals for subsequent access, so that all terminals do not need to access, thereby avoiding the subsequent access process of those terminals that do not need access, and reducing the transmission resources used for access.

[0057] 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.

[0058] The network device 101 is connected to the terminal 102 in communication. The network device 101 can be a transmitting device such as a reader / writer, a base station side device (such as a base station), an access network device, etc. For example, the network device 101 can be a base station antenna, a customized reader / writer, a device that sends instructions to the terminal on the network side, etc.; the terminal 102 can be an IoT device, a passive IoT device, a tag, an electronic price tag, etc., etc.

[0059] In the present application, the network device 101 may send a first indication message to the terminal 102. Afterwards, the terminal 102 may receive the first indication message sent by the network device 101 and send a first feedback message to the network device 101. Subsequently, the network device 101 may receive first feedback messages sent by multiple terminals 102 and obtain attribute information in the first feedback messages. Then, the network device 101 may determine the target terminal based on the attribute information of the multiple terminals, that is, the terminal determined by the network device 101 that needs to be subsequently processed.

[0060] 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).

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] As an embodiment, the processor 21 may include one or more CPUs, such as Figure 2 CPU 0 and CPU 1 are shown in .

[0067] 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.

[0068] 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.

[0069] 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.

[0070] In another possible implementation, the memory 22 may also be integrated with the processor 21 .

[0071] 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.

[0072] 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.

[0073] 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.

[0074] The communication method provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0075] 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:

[0076] S301. A network device sends a first indication message.

[0077] The first indication message is used to instruct the terminal to report a temporary identifier during the random access process. Optionally, the first indication message may include terminal screening information, silencing non-related terminals, and other messages. The first indication message may be an inventory, inventory, count, search, and other messages.

[0078] 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.

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

[0080] S302: The terminal receives a first indication message and sends a first feedback message.

[0081] The first feedback message is used to indicate the temporary identifier of the terminal and the attribute information of the terminal. Optionally, the temporary identifier may be a random number, and the random number may be carried in a bit at a random position in the first feedback message.

[0082] After receiving the first indication message, the terminal may send a first feedback message to the terminal in response to the first indication message, and indicate the temporary identification and attribute information of the terminal through the first feedback message. In this way, after receiving the first feedback message, the network device may determine the target terminal that it needs to process based on the attribute information of the terminal, and determine to access only the target terminal. In this way, terminals other than the target terminal may not need to perform subsequent access procedures, thereby avoiding the waste of transmission resources for access by these terminals that do not need access. In addition, the network device only accesses the target terminal, thereby reducing redundant operations and improving the operating efficiency of the network device.

[0083] In a possible implementation, the first indication message is also used to indicate multiple candidate resources for the terminal to report 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.

[0084] It should be understood that the temporary identifier can 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.

[0085] In some embodiments, Figure 4 A schematic diagram showing a communication method Figure 2 . Combined Figure 3 ,like Figure 4 As shown, the method provided in the embodiment of the present application also includes:

[0086] S401. A network device receives a first feedback message, and determines a target terminal based on attribute information of a terminal in at least one first feedback message.

[0087] The target terminal is a terminal to be accessed determined by the network device.

[0088] After receiving at least one first feedback message sent by at least one terminal, the network device can determine the terminal to be accessed based on the attribute information in the at least one first feedback message. After that, the network device can determine the random code corresponding to the temporary identifier and determine the unique channel with the target terminal, so that the network device can send the second indication message based on the unique channel. For example, the network device can determine a certain type of terminal to be processed based on the type in the attribute information. In this way, the network device can only access this type of terminal, thereby avoiding wasting access transmission resources for other terminals.

[0089] In addition, these terminals that have established channels can be marked as successful reporting terminals in the network device, while unsuccessful reporting terminals do not participate in the subsequent access process of the current round.

[0090] S402: The network device sends a second indication message to the target terminal.

[0091] The second indication message is used to instruct the terminal to report a fixed identifier during the random access process. Optionally, the second indication message may include a temporary identifier in the target, so that the target terminal can determine that it needs to send a second feedback message based on the target terminal. The fixed identifier is related to the terminal physical device and is unique. It can be an electronic product code (EPC). The network device can (for example, on the background server side of the base station) obtain the correspondence between the fixed identifier and the device.

[0092] It should be pointed out that when at least one first terminal feeds back a first feedback message, there may be a first terminal that fails to receive the first feedback message sent by these first terminals due to a conflict. In this case, these terminals that fail to feed back the first feedback message wait for the next round of random access process (do not participate in the subsequent access process of the current access round).

[0093] In a possible implementation, the network device may send a silent message to the terminals except the target terminal among the terminals that have reported successfully, so that these terminals no longer participate in the access process of subsequent rounds, thereby avoiding repeated activation and reporting.

[0094] S403: The terminal receives the second indication message, and sends a second feedback message to the network device.

[0095] The second feedback message includes the 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] Correspondingly, after receiving the second feedback message, the network device can send an operation instruction (which can be one or more) to the target terminal, such as modifying the label information and other operations. After receiving the operation instruction, the target terminal can send a third feedback message to the network device to indicate that it has completed (or not completed) the operation and remain silent. Alternatively, the third feedback message may not be sent, and the next inventory instruction may be waited for. Optionally, the operation instruction can be a command that the terminal's subordinate device needs to perform. The network device gives a signal, the terminal transmits it, and the subordinate device executes it. For example, if the terminal is an electronic price, the price is modified; it can also be a command issued to the terminal, such as destroying the terminal (clearing information and no longer responding), modifying the content in the terminal memory, etc.

[0098] In some embodiments, the attribute information of the terminal is carried in bits at a preset position in the first feedback message. In this way, the network device can determine the attribute information of the terminal from the preset position.

[0099] In addition, there are multiple ways for the terminal to carry the attribute information of the terminal based on the first feedback message. The following describes multiple ways of carrying the attribute information.

[0100] Mode 1: The first feedback message includes a fixed codeword and a random codeword, the fixed codeword is used to indicate the attribute information of the terminal, and the random codeword is used to indicate the temporary identifier of the terminal.

[0101] Since the temporary identifier of the terminal can be a string of random numbers, that is, a string of random codewords in the first feedback message, the terminal can indicate the temporary identifier and attribute information of the terminal respectively through the random codeword and the fixed codeword, that is, the random codeword is used to indicate the temporary identifier, and the fixed codeword is used to indicate the attribute information. In this way, since both the random codeword and the fixed codeword are carried on the bits at the preset position, the network device can determine the random codeword and the fixed codeword based on the bits at the preset position, which is more effective.

[0102] Mode 2: The first feedback message includes a random code, at least one fixed codeword in the random code is used to indicate attribute information of the terminal, and codewords other than the at least one fixed codeword in the random code are used to indicate a temporary identifier of the terminal.

[0103] Since the random code is composed of multi-bit code words, the terminal can select at least one code word from the multi-bit code words in the random code as a fixed code word. In this way, the terminal can indicate the attribute information of the terminal through the fixed code words in the random code, and use other code words in the random code except the fixed code words to indicate the temporary identification of the terminal. Since the bit position of the fixed code word in the random code word is fixed, the network device can determine the attribute information from the bit at the fixed position in the random code word, and determine the temporary identification through other bits in the random code word.

[0104] In a possible implementation, the fixed codeword can be used to indicate the type of the terminal, and the type of the terminal can be classified by the power of the terminal, or can be classified according to whether the above-mentioned operation instruction can be executed. Taking the fixed codeword occupying two bits as an example, the fixed codeword 00 (i.e., the value of the bit) can indicate that the terminal type is a reflection-only terminal without an amplifier, 01 can indicate that the terminal type is a reflection-only terminal with an amplifier, 10 can indicate that the terminal type is an active reflection terminal with an amplifier, and 11 can indicate that the terminal type is a terminal that can both reflect and actively transmit signals.

[0105] Figure 5 A schematic diagram of a fixed codeword and a random codeword is shown. Exemplarily, the terminal can represent a temporary identifier by a 16-bit random code (RN16). The first random code (or random codeword) is a general RN16, and 16 is a random code (0 or 1) used to identify the temporary identifier of the terminal. The second random code is a random codeword combined with a fixed codeword. For example, in a string of bit sequences, the first two bits are fixed codewords, and the following are random codewords (or the fixed codeword and the random codeword may not be adjacent). The third random code is to determine the first two bits in RN16 as fixed codewords, and the remaining bits in the random code are determined as codewords representing temporary identifiers (or the fixed codewords may also be other fixed positions in RN16).
