Technical Field

[0003] The present disclosure relates to the field of communication technologies, and in particular to an information processing method, device, and readable storage medium. Background Art

[0122] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0123] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0124] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0125] Uncoordinated Random Access and Transmission (URAT) technology supports a massive number of terminals with minimal or no coordination between the network and terminals. Because URAT communication is uncoordinated and initiated by the terminal, there is no connection between the terminal and the network device, and it is not point-to-point communication. Therefore, the network device cannot confirm the terminal's identity. If the network device cannot determine the terminal's identity, it cannot authenticate and identify the terminal, nor can it use existing encryption based on terminal identity information. Furthermore, the network device cannot match received application data to the terminal device, making it impossible to determine which terminal device sent the data packet.

[0126] The embodiments of the present disclosure provide an information processing method and apparatus to ensure the reliability of communication.

[0127] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0128] Referring to FIG1 , FIG1 is a flowchart of one of the information processing methods provided by an embodiment of the present disclosure, as shown in FIG1 , comprising the following steps:

[0129] Step 101: A terminal sends its identity information to a network device.

[0130] In the embodiment of the present disclosure, the identity information of the terminal may only include the terminal identifier. The terminal identifier includes the terminal identifier that can be obtained in the RRC_IDLE state, such as the 5G S-Temporary Mobile Subscription Identifier (5G-S-TMSI). In specific applications, some or all bits in the 5G-S-TMSI can be used as the identity information of the terminal. The terminal identifier carried can be uniquely identified, thereby facilitating the network device to associate the terminal identity with the terminal data.

[0131] Alternatively, the identity information of the terminal includes: a first field, a terminal identifier, and a second field, where the first field indicates one or more of the following:

[0132] whether the identity information includes the second field;

[0133] The content of the second field.

[0134] For example, the identity information of the terminal includes: an indication field (i.e., a first field), a terminal identifier, and an additional field (i.e., a second field). The indication field is used to indicate the content of the additional field in the identity information; alternatively, the indication field may be used only to indicate whether the identity information includes the additional field; alternatively, the indication field may indicate both of the above situations. The additional field may include information other than the terminal identifier, such as data control information, application layer service data information, etc. The terminal identifier may also be a 5G-S-TMSI, etc.

[0135] For example, when the indicator field value is "0," it indicates no additional fields. When the indicator field value is not "0," it corresponds to different additional field message contents. For example, a "1" indicator field indicates that the additional field is data control information; a "2" indicator field indicates that the additional field is application layer service data information. Therefore, the additional field can transmit data control information and application layer service data information necessary for URAT communication.

[0136] In the embodiment of the present disclosure, the terminal may send the identity information of the terminal to the network device before or during URAT.

[0137] If the terminal sends its identity information to the network device before URAT, the terminal may send the identity information to the network device via an RRC message over SRB0. The RRC message may reuse an existing RRC message, such as an RRC Setup Request message, or use a new RRC message defined for carrying the terminal's identity information in URAT communication, such as an RRC URAT Request message.

[0138] Optionally, in this case, the terminal may further use part or all of the identity information to scramble the UART data to be sent, and send the scrambled UART data to the network device. For example, the terminal may scramble the PUSCH data of the UART data, or scramble the cyclic redundancy check (CRC) check bits of the PUSCH data. In this way, the identity information of the terminal can be more accurately associated with the URAT communication process, making it easier for the network device to determine the URAT communication process corresponding to the terminal.

[0139] If the terminal sends the identity information of the terminal to the network device during URAT communication, the terminal may send URAT data (including a preamble and PUSCH data) to the network device, wherein the preamble part of the URAT data carries the identity information, or the PUSCH data part of the URAT data carries the identity information.

[0140] That is, the terminal can carry the identity information of the terminal during the URAT communication process (including the transmission of the preamble and PUSCH data), which can be carried through the preamble or the PUSCH data.

[0141] If the terminal's identity information is carried in the preamble, the terminal may further use part or all of the identity information to scramble the PUSCH data of the URAT data, for example, to scramble the CRC check bits of the PUSCH data.

[0142] In the embodiment of the present disclosure, the preamble portion may carry the identity information of one or more terminals. If the preamble carries the identity information of multiple terminals, communication resources can be further saved and communication efficiency can be improved.

[0143] In URAT communication, a terminal sends its identity information to a network device, allowing it to associate the sent identity information with URAT data. When receiving data, the network device can determine which terminal sent the received URAT data based on the terminal identity information associated with the URAT data.

[0144] In the embodiment of the present disclosure, the identity information sent by the terminal to the network device includes the terminal's identity identifier. Therefore, the network device can accurately determine the terminal's identity based on the terminal identifier, thereby ensuring the reliability of subsequent communications.

[0145] Referring to FIG. 2 , FIG. 2 is a second flowchart of the information processing method provided by an embodiment of the present disclosure. As shown in FIG. 2 , the method includes the following steps:

[0146] Step 201: A network device receives identity information sent by a terminal.

[0147] The identity information includes: a terminal identifier; or the identity information includes: a first field, a terminal identifier, and a second field, where the first field indicates one or more of the following:

[0148] whether the identity information includes the second field;

[0149] The content of the second field.

[0150] Specifically, for the explanation of identity information, reference may be made to the description of the aforementioned embodiment.

[0151] In this step, the network device may receive the identity information sent by the terminal before or during URAT.

[0152] Specifically, the network device may receive the identity information sent by the terminal through an RRC message on SRB0 before URAT. In this case, the network device may also receive scrambled UART data sent by the terminal, and if the identity information is authenticated, the network device descrambles the scrambled UART data using part or all of the identity information.

[0153] In the embodiments of the present disclosure, the manner in which the network device authenticates identity information is not limited, and any authentication manner that can be adopted by the network device can be adopted.

[0154] Specifically, the network device may receive the URAT data sent by the terminal, and obtain the identity information from a preamble portion of the URAT data, or obtain the identity information from a PUSCH data portion of the URAT data.

[0155] If the network device obtains the identity information from the preamble part of the URAT data, the network device can receive the scrambled PUSCH data sent by the terminal, and use part or all of the identity information to descramble the scrambled PUSCH data, so that after descrambling, the identity information of the terminal and the PUSCH data are matched.

[0156] In practical applications, a pre-agreed method can be used to determine whether the terminal side uses part or all of the identity information to scramble the PUSCH data. Alternatively, the terminal side can notify the network device of the scrambling method used by the terminal side. Alternatively, the terminal side can use a default method. Accordingly, the network device can refer to the scrambling method on the terminal side and use part or all of the identity information to descramble the scrambled PUSCH data.

[0157] If the preamble carries the identity information of one or more terminals, the network device can simultaneously obtain the identity information of one or more terminals and authenticate the one or more identity information. If the identity information of multiple terminals is obtained simultaneously, the network device can use the identity information of the multiple terminals to descramble the subsequently obtained scrambled UART data, thereby accurately identifying the UART data of the multiple terminals after successful descrambling.

[0158] In the embodiment of the present disclosure, the identity information sent by the terminal to the network device includes the terminal's identity identifier. Therefore, the network device can accurately determine the terminal's identity based on the terminal identifier, thereby ensuring the reliability of subsequent communications.

[0159] Optionally, based on the above embodiment, if the identity information includes a first field, a terminal identifier, and a second field, the network device may also determine the content of the second field based on the first field, thereby carrying out subsequent communications normally.

[0160] In one embodiment of the present disclosure, the identity information of the terminal is sent before the URAT communication process.

[0161] As shown in Figure 3, a terminal device in the RRC_IDLE state can first send the terminal's identity information based on SRB0 (for example, it can be sent using the Common Control Channel (CCCH)) before performing the URAT communication process, so that the network device can determine the identity of the terminal. Furthermore, the terminal can use all or part of the bits in the terminal's identity information to scramble the PUSCH data sent during the URAT communication process, for example, it can scramble the PUSCH data, or scramble the CRC check bits of the PUSCH data. When the network device performs receiving processing during the URAT communication process, it descrambles the PUSCH data according to the received terminal's identity information. If the descrambling is successful, the PUSCH data and the terminal's identity information can be matched, that is, the network device can determine which terminal device sent the PUSCH data.

[0162] Specifically, the terminal transmits its identity information via an RRC message over SRB0. The terminal uses part or all of the terminal's identity information to scramble the URAT data to be transmitted and sends the scrambled URAT data to the network device. This RRC message can reuse an existing RRC message, such as an RRC Setup Request message, or a new RRC message, such as an RRC URAT Request, can be used to carry the terminal's identity information in URAT communications.

[0163] The network device receives the RRC message over SRB0 and obtains the terminal's identity information. Based on the received terminal's identity information, the network device identifies and authenticates the terminal. The network device receives URAT data on the URAT receive time-frequency resources and descrambles the received URAT data using the authenticated terminal's identity information. If descrambling is successful, the received URAT data is associated with the terminal after data reception is complete.

[0164] If a network device receives RRC messages from multiple terminals at the same time, it will receive the identity information of multiple terminals, such as the identity information of 6 terminals, UE identity (UE ID) 0 to UE ID5. The network device can identify and authenticate the identity information of these 6 terminals separately, and then obtain the identity information of x (x≤6) terminals that have passed the authentication, which means that corresponding data reception processing is required. For terminals that have not passed the authentication, data reception processing can be omitted. When URAT data sent by multiple terminals is received at the same time, the data can be descrambled based on the identity information of the authenticated terminals, and then the URAT data and the terminal identity information can be matched, so as to determine which terminal sent the URAT data.

[0165] In one embodiment of the present disclosure, the identity information of the terminal is sent during the URAT communication process.

[0166] The transmission of the terminal's identity information can be combined with the transmission of URAT data. The terminal's identity information is transmitted when the URAT data is transmitted. Considering that URAT data can be divided into a preamble portion and a PUSCH data portion, the transmission of the terminal's identity information can also be considered to be carried in the preamble or in the PUSCH data.

[0167] Figure 4 shows a schematic diagram of a terminal's identity information carried in a preamble. In specific applications, the preamble used for URAT communication can be determined based on the terminal's identity information, and some or all of the terminal's identity information can be used to scramble the PUSCH data to be transmitted. Carrying the terminal's identity information in the preamble uniquely identifies the terminal device, and using some or all of the terminal's identity information to scramble the PUSCH data allows the preamble and PUSCH data to be associated.

[0168] Specifically, the terminal determines the preamble to be used based on the terminal's identity information and sends the preamble. The terminal uses part or all of the terminal's identity information to scramble the PUSCH data to be sent and sends the scrambled PUSCH data to the network device.

[0169] The mapping relationship between the terminal's identity information and the preamble may include any of the following:

[0170] Method 1: The terminal's identity information is mapped to the preamble code one by one. In this case, each preamble code can uniquely correspond to the identity information of a terminal. For example, if the terminal's identity information is 32 bits, it requires 2 32 Different preamble codes.

[0171] Method 2 uses a many-to-one mapping between terminal identity information and preambles. This method can save preamble resource overhead. For example, if there are 512 different terminals sharing 64 preambles, the identity information of the 512 terminals can be associated with the 64 preambles. For example, the terminal identity information can be modulo the number of preambles to obtain the preamble index corresponding to the terminal identity information. In this way, each terminal identity information corresponds to a unique preamble, and each preamble corresponds to the identity information of eight terminals. Therefore, when a network device receives a preamble, each received preamble corresponds to the identity information of eight possible terminals. The network device can first identify and authenticate these eight terminals, then obtain the identity information of x (x ≤ 8) authenticated terminals. The network device then descrambles the data based on the identity information of these x terminals. Once the data is descrambled, it can be determined which of these x possible terminals the data corresponds to.

[0172] The network device receives the preamble sent by the terminal and determines the terminal's identity based on the received preamble. The network device then identifies and authenticates the terminal based on the determined terminal's identity. The network device receives URAT data on the URAT receive time-frequency resources and descrambles the URAT data based on the authenticated terminal's identity. If descrambling is successful, the URAT data can be associated with the terminal's identity to identify the terminal that sent the URAT data.

[0173] Figure 5 shows a schematic diagram of how terminal identity information is carried in PUSCH data. The terminal can directly occupy the corresponding bits in the PUSCH data to be sent to transmit the terminal identity information. The terminal identity information can be sent at the beginning or end of the PUSCH data.

[0174] In this way, regardless of whether the terminal device can pass the identification and authentication of the network device, the network device needs to perform URAT communication reception processing first.

[0175] As can be seen from the above description, in the disclosed embodiments, the terminal sends identity information to the network device, allowing the network device to uniquely determine the terminal's identity.
