Description

Data state transfer method, base station, device and medium

technical field

Embodiments of the present invention relate to the field of communications technologies, and in particular, to a data state transfer method, base station, and device.

Background technique

In the future 5G network construction, 5G can be used as a macro coverage independent network, or 5G micro cells can be used for hotspot coverage. No matter which networking method is adopted, a DC (Dual Connectivity, dual connectivity) function similar to that in LTE can be introduced into the 5GNR system. Among them, DC refers to the traffic distribution between multiple base stations via PDCP (Packet Data Convergence Protocol, Packet Data Convergence Protocol) under the condition of non-ideal transmission link, that is, the wireless resources of multiple base stations are concentrated to provide services for users . By introducing the DC function in the 5GNR system, the utilization of radio resources can be improved, the system switching delay can be reduced, and the user and system performance can be improved.

In addition, when a network service (UE User Equipment, user equipment) is moving from the source cell to the target cell, or when there are situations such as wireless transmission service load adjustment, activation operation and maintenance, equipment failure, etc., the UE can be connected to the source base station. The communication link is switched to the target base station, that is, the handover of the communication link is realized. By introducing the above handover function in the 5GNR system, the continuity of communication and the quality of service can be guaranteed.

For the scenario corresponding to the above DC function, that is, in the DC scenario, the following situations may exist: A communication link is established between the UE and the primary base station, and the UE performs uplink and downlink data transmission with the primary base station through the communication link. When the UE enters the coverage of the secondary base station, a communication link can be established between the UE and the secondary base station, so that data transmission can be performed in a dual-connection manner. At this time, the UE may perform uplink and downlink data transmission with the primary base station, and may also perform uplink and downlink data transmission with the secondary base station. For a service, the data transmission process between the UE and the primary base station may not be completed, so after the UE establishes a communication link with the secondary base station, the secondary base station can also perform uplink and downlink data transmission with the UE for the same service. In order to coordinate the process of uplink and downlink data transmission, the secondary base station needs to obtain the confirmation status of the data packets when the UE transmits data with the primary base station, that is, the data status needs to be transferred from the primary base station to the secondary base station.

For example, taking the downlink data transmission process as an example, the master base station needs to deliver 100 data packets to the UE. When the UE confirms the third data packet, the UE moves to the coverage of the secondary base station and establishes a communication connection with the secondary base station. At this time, the primary base station may send the UE to confirm the status of the data packet to the secondary base station. In this example, the primary base station may send the status of the UE acknowledgment data packet to the secondary base station, that is, inform the secondary base station that the UE has confirmed the third data packet, so that the secondary base station can start to deliver the fourth data packet.

For the scenario corresponding to the above handover function, that is, in the handover scenario, the following situations may exist: A communication link is established between the UE and the source base station, and the UE performs uplink and downlink data transmission with the source base station through the communication link. When the UE switches from the source base station to the communication link of the target base station, since the previous process of uplink and downlink data transmission between the UE and the source base station may not be completed, after the UE switches to the communication link of the target base station, the UE and the source base station may not be completed. The communication link between the source base stations will be disconnected, so in order for the target base station to continue to perform uplink and downlink data transmission, the target base station needs to obtain the confirmation status of the data packets when the UE transmits data with the main base station, that is, the data status needs to be obtained from the main base station. Transfer to the secondary base station.

Based on the above DC or handover scenario, a data status transfer method is provided in the related art, which mainly includes sending a sequence number status transfer (SN Status Transfer) message from the first base station to the second base station.

For the DC scenario, the first base station is the primary base station and the second base station is the secondary base station. For a handover scenario, the first base station is the source base station, and the second base station is the target base station. Wherein, the serial number state transition message includes the count value corresponding to the next data packet of the last data packet whose transmission confirmation is completed under the current batch. For a service, it can include multiple batches of data packet transmission processes. All data packets in each batch are sorted in sequence, and each data packet in each batch can correspond to a count value.

For example, taking the downlink data transmission process in the handover scenario as an example, if the source base station needs to send 100 data packets to the UE in the current batch, and the UE determines that the third data packet is reached, the UE is switched from the source base station to the target communication link of the base station. At this time, the source base station may send a sequence number state transition message to the target base station. The sequence number state transition message includes the sequence number corresponding to the next data packet of the last data packet confirmed by the downlink transmission in the current batch. In this example, the sequence number corresponding to the next data packet of the last data packet for which downlink transmission confirmation is completed under the current batch is 4, so that the target base station can start to deliver the fourth data packet.

In the process of implementing the embodiments of the present invention, it is found that the related technology has at least the following problems: for a service, it may include multiple batches of data transmission processes. Since the sequence number state transfer message sent by the first base station to the second base station or UE only contains the count value corresponding to the next data packet of the last data packet of the completed transmission acknowledgment, the second base station or the UE cannot determine the corresponding value of the count value. Which batch the packet belongs to. This makes it possible that in the subsequent data transmission process, data packets may be lost or repeated transmission of data packets due to batch determination errors. Therefore, the correct transmission of data cannot be guaranteed.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Aiming at the problems in the related art, an embodiment of the present invention provides a data state transfer method. The method provided by the embodiment of the present invention is applicable to the data transmission process between the UE and the base station in the DC or handover scenario. The data transmission process may include uplink data transmission and downlink data transmission. For DC scenarios, base stations can be divided into primary base stations and secondary base stations. For handover scenarios, base stations can be divided into source base stations and target base stations. For the first base station and the second base station appearing in subsequent embodiments, if the application scenario of this embodiment is a DC scenario, the first base station corresponds to the primary base station, and the second base station corresponds to the secondary base station. If the application scenario of this embodiment is a handover scenario, the first base station corresponds to the source base station, and the second base station corresponds to the target base station.

The data state transition method provided by the embodiment of the present invention will now be described by taking the execution subject as the first base station. Referring to Figure 1, the method includes:

101. When it is detected that the UE establishes a communication connection with the second base station, obtain the count value corresponding to the next data packet of the last data packet of the completed transmission confirmation; 102. Pass the count value to the second base station or UE, so that the first The base station or the UE performs data transmission based on the count value.

Wherein, each data packet is obtained by dividing the data file. After all the divided data packets are sorted in sequence, each data packet corresponds to a count value, and each count value is the sequence number of each data packet after sorting.

For the downlink data transmission in the handover scenario, the data file can be stored in the core network and divided into data packets according to the above method. The first base station obtains data packets from the core network through the data link with the core network, and sequentially delivers the data packets to the UE. After the UE establishes a communication connection with the second base station, the second base station may establish a data link with the core network through an MME (Mobility Management Entity, key control node) to obtain data packets from the core network based on the same data file.

For downlink data transmission in the DC scenario, the data file can be stored in the main base station and divided into data packets in the above-mentioned manner. The primary base station can transmit a certain number of data packets to the secondary base station according to the delivery requirements, and the secondary base station assists in delivery.

For uplink data transmission in a handover scenario or a DC scenario, the data file is stored in the UE, and can be divided into data packets in the above manner.

In the method provided by the embodiment of the present invention, the first base station obtains the count value corresponding to the next data packet of the last data packet for which the transmission confirmation is completed when detecting that the UE establishes a communication connection with the second base station. The count value is communicated to the second base station or UE, so that the second base station or UE performs data transmission based on the count value. Since each data packet is obtained by dividing the data file, after all the divided data packets are sorted in sequence, each data packet corresponds to a count value, that is, the count value corresponding to each data packet is in all divided data packets. The actual sequence number, so that in the process of data state transition, the corresponding data packet can be uniquely confirmed based on the count value, and no data packet loss or repeated data packet transmission will be caused by batch determination errors. Therefore, the correct transmission of data can be guaranteed.

As an optional embodiment, before transmitting the count value to the second base station or the UE, the method further includes:

According to the first preset method, the count value is preprocessed to obtain the count information corresponding to the count value, including:

Determine the bitmap data on each bit based on the data transmission result and count value corresponding to each data packet that has completed the transmission confirmation;

Based on the bitmap data on each bit, a corresponding binary bitmap file is generated.

The bitmap file refers to an image represented by a pixel array, and the color information of each pixel is represented by an RGB combination or a grayscale value. According to the data bits required for color information, it can be divided into 1, 4, 8, 16, 24 and 32 bits, etc. The higher the number of bits, the richer the color and the greater the corresponding data volume. Among them, a bitmap that uses 1 bit to represent the color of a pixel is also called a binary bitmap because one data bit can only represent two colors. The file corresponding to the binary bitmap is the binary bitmap file.

As an optional embodiment, according to the first preset method, the count value is preprocessed to obtain the count information corresponding to the count value, including:

According to the first preset algorithm, the count value is operated to obtain count information corresponding to the count value.

As an optional embodiment, according to the first preset algorithm, the count value is operated, and before the count information corresponding to the count value is obtained, the method further includes:

determining the used first preset algorithm based on the interaction information between the first base station and the second base station;

Wherein, the interaction information includes an instruction for selecting a preset algorithm.

As an optional embodiment, the count information is an offset value;

According to the first preset algorithm, the count value is operated to obtain the count information corresponding to the count value, including:

Based on the preset offset, an offset operation is performed on the count value to obtain an offset value corresponding to the count value.

As an optional embodiment, the count information is a binary string;

According to the first preset method, the count value is preprocessed to obtain the count information corresponding to the count value, including:

Based on the data transmission result and the count value corresponding to each data packet for which the transmission confirmation is completed, the value on each binary bit is sequentially determined to obtain a binary string.

All the above-mentioned optional technical solutions can be combined arbitrarily to form optional embodiments of the present invention, which will not be repeated here.

Based on the contents of the foregoing embodiments, the embodiments of the present invention provide a data state transfer method. The data state transition method provided by the embodiment of the present invention will now be described by taking the execution subject as the first base station. Referring to FIG. 2, the method includes: 201. When detecting that the UE establishes a communication connection with the second base station, obtain a count value corresponding to the next data packet of the last data packet that has completed the transmission confirmation; 202. According to the first preset method , preprocess the count value to obtain count information corresponding to the count value; 203 , send the count information to the second base station or the UE.

Wherein, 201, when it is detected that the UE establishes a communication connection with the second base station, obtain a count value corresponding to the next data packet of the last data packet of the completion of the transmission confirmation.

Before performing this step, the data files to be transmitted can be divided in advance, that is, the data files are divided into data packets. After all the divided data packets are sorted in sequence, each data packet corresponds to a count value, and each count value is each data packet. The sequence number of the packet after sorting. For the storage location of the data file and the data flow direction, reference may be made to the content of the corresponding embodiment in FIG. 1 .

For uplink data transmission in the handover scenario, that is, the UE uploads data packets to the source base station (the first base station), and when it is detected that the UE has established a communication connection with the target base station (the second base station), the source base station can obtain the final confirmation of the completion of the uplink transmission. The count value corresponding to the next packet of a packet. For example, when the UE uploads a data packet to the source base station, for any uploaded data packet, if the source base station receives the data packet, it can return the confirmation information corresponding to the data packet to the UE to inform the UE that the data packet was uploaded successfully. . When the data packet corresponding to the acknowledgment information sent by the source base station to the UE last is the third data packet, the source base station can obtain the count value corresponding to the next data packet of the last data packet confirmed by the uplink transmission, which is 4.

For the downlink data transmission in the handover scenario, that is, the source base station sends a data packet to the UE, when it is detected that the UE has established a communication connection with the target base station, the source base station can obtain the last data packet that has completed the downlink transmission confirmation. The corresponding count value. For example, when the source base station sends a data packet to the UE, for any sent data packet, if the UE receives the data packet, it can return the acknowledgment information corresponding to the data packet to the source base station to inform the source base station of the data packet. The delivery is successful. When the data packet corresponding to the acknowledgment information sent by the UE to the source base station last is the third data packet, the source base station can obtain the count value corresponding to the next data packet of the last data packet for which the downlink transmission acknowledgment is completed, which is 4.

For uplink data transmission in the DC scenario, that is, the UE uploads data packets to the primary base station (the first base station), and when it is detected that the UE has established a communication connection with the secondary base station (the second base station), the primary base station can obtain the final confirmation of the completion of the uplink transmission. The count value corresponding to the next packet of a packet. For example, when the UE uploads a data packet to the main base station, for any uploaded data packet, if the main base station receives the data packet, it can return the confirmation information corresponding to the data packet to the UE to inform the UE that the data packet was uploaded successfully. . When the data packet corresponding to the acknowledgment information sent by the master base station to the UE last is the third data packet, the master base station can obtain the count value corresponding to the next data packet of the last data packet confirmed by the uplink transmission, which is 4.

For downlink data transmission in the DC scenario, that is, the primary base station sends a data packet to the UE, and when it is detected that the UE has established a communication connection with the secondary base station, the primary base station can obtain the information of the next data packet of the last data packet confirmed by the downlink transmission. The corresponding count value. For example, when the primary base station sends a data packet to the UE, for any delivered data packet, if the UE receives the data packet, it can return the acknowledgment information corresponding to the data packet to the primary base station to inform the primary base station of the data packet. The delivery is successful. When the data packet corresponding to the acknowledgment information sent by the UE to the master base station last is the third data packet, the master base station can obtain the count value corresponding to the next data packet of the last data packet for which the downlink transmission confirmation is completed, which is 4.

Wherein, 202: Preprocess the count value according to a first preset manner to obtain count information corresponding to the count value.

Through the above step 201, the first base station can obtain the count value. At this time, the first base station may directly transmit the count value to the second base station or the UE. But in order to ensure the security of the count value during the transmission process, and to facilitate the verification of the correctness of the count value. When the first base station transmits the count value to the second base station or the UE, the count value may be preprocessed first.

This embodiment of the present invention does not specifically limit the manner in which the first base station preprocesses the count value according to the first preset manner to obtain the count information corresponding to the count value, including but not limited to: corresponding to each data packet based on the completion of transmission confirmation The data transmission result and count value of , determine the bitmap data on each bit; based on the bitmap data on each bit, generate the corresponding binary bitmap file.

The generated binary bitmap file is the count information corresponding to the count value. The value of each bitmap data in the binary bitmap file is 1 or 0, which can be used to represent the data transmission result of the data packet. For any data packet, if the bitmap data value corresponding to the data packet is 1, it can indicate that the data packet is successfully transmitted. If the bitmap data value corresponding to the data packet is 0, it means that the transmission of the data packet fails. Alternatively, if the bitmap data value corresponding to the data packet is 1, it may indicate that the data packet transmission fails. If the bitmap data value corresponding to the data packet is 0, it means that the data packet is transmitted successfully.

For example, take downlink data transmission in a handover scenario as an example. If the source base station sends 10 data packets to the UE, and the UE has completed the downlink transmission confirmation for these 10 data packets, the count value can be determined to be 11. Take 1 for successful data transmission and 0 for data transmission failure as an example. As the first 10 packets complete the downlink transmission acknowledgment. Therefore, the bitmap data corresponding to the first 10 data packets can be represented by the following binary string 1111111111.

Wherein, the number of digits of the above binary string is 10, which is the total amount of data packets for which the downlink transmission is confirmed. Since the target base station needs to send the 11th data packet to the UE later, and the 11th data packet has not been sent to the UE, it can correspond to the transmission failure, so the corresponding bitmap data can be processed by the following binary string 11111111110 express.

After the bitmap data is obtained through the above process, a corresponding binary bitmap file can be generated based on the bitmap data, the bitmap data identifier, the bitmap information header and other data. Specific restrictions. Since the bitmap file has its own data verification attribute, the count value is passed through the bitmap file, which can facilitate subsequent verification of the correctness of the count value. In addition, compared with directly passing the count value, carrying the count value through a bitmap file and passing the count value by sending the count bitmap file can ensure the security of the count value during the transfer process.

In the above process, the count information is mainly represented by a binary bitmap file, and then the count value is transmitted by sending the binary bitmap file. Of course, in addition to the above methods, the count value can also be passed in other ways. Specifically, the embodiment of the present invention does not specifically limit the manner in which the first base station preprocesses the count value according to the first preset method to obtain the count information corresponding to the count value, including but not limited to: according to the first preset algorithm, The count value is operated to obtain the count information corresponding to the count value.

The first preset algorithm may be an algorithm with encryption and/or verification attributes, which is not specifically limited in this embodiment of the present invention. Correspondingly, the count information is obtained by operating the count value through the first preset algorithm, and the transfer of the count value is realized based on the count information, which can ensure the security of the transfer of the count value. In addition, it can also facilitate subsequent verification of the correctness of the count value.

The first base station operates on the count value by using the first preset algorithm to obtain corresponding count information. After the first base station sends the count information to the second base station or the UE, the second base station or the UE may operate the count information through a second preset algorithm to obtain the count value. The first preset algorithm may be pre-configured on the first base station by means of network configuration, and the second preset algorithm may be pre-configured on the first base station or the UE by means of network configuration.

It should be noted that, for the DC scenario, the first base station is not only used as the primary base station, but may also be used as the secondary base station. The second base station is not only used as a secondary base station, but may also be used as a primary base station. For a handover scenario, the first base station is not only used as a source base station, but may also be used as a target base station. The second base station is not only used as a target base station, but may also be used as a source base station. Therefore, when the first preset algorithm and the second preset algorithm are configured on the base station side by means of network configuration, the first base station side can configure the first preset algorithm and the second preset algorithm at the same time, and the second base station side can also configure the first preset algorithm and the second preset algorithm. The first preset algorithm and the second preset algorithm may be configured at the same time, which is not specifically limited in this embodiment of the present invention.

In addition to the above-mentioned manner of determining the preset algorithm by means of network configuration, the preset algorithm to be used may also be negotiated between the base stations and between the base station and the UE. Through the negotiation process, the base station and the UE can select the applicable preset algorithm according to the requirements. For example, when the base stations currently occupy more processing resources, the base stations and between the base stations and the UE may negotiate to use a preset algorithm that occupies less resources. Through the negotiation process, the method provided by the embodiment of the present invention can be more suitable for an actual communication scenario.

Correspondingly, before the first base station calculates the count value according to the first preset algorithm and obtains the count information corresponding to the count value, the first base station may further determine the number of counts based on the interaction information between the first base station and the second base station. The first preset algorithm to use. Wherein, the interaction information includes an instruction for selecting a preset algorithm. The first base station and the second base station may negotiate the used preset algorithm through an instruction for selecting a preset algorithm between them.

For example, in a downlink data transmission in a handover scenario, the first base station side is configured with five first preset algorithms, and the second base station side is configured with five second preset algorithms as an example. Wherein, each first preset algorithm corresponds to one second preset algorithm. The target base station may send interaction information to the source base station, and inform the source base station through the interaction message that it intends to select the third second preset algorithm. If the third second preset algorithm corresponds to the third first preset algorithm, after receiving the interaction message, the source base station may determine that the used first preset algorithm is the third first preset algorithm.

It should be noted that the above example is mainly a process in which one base station implements algorithm selection by sending interaction information, that is, the target base station sends interaction information to the source base station to inform itself of the algorithm selected, so that the source base station determines its own algorithm based on the interaction information. algorithm used. Of course, the source base station can also determine the algorithm used by itself, and then send the interaction information to the target base station, so that the target base station determines the algorithm used by the target base station according to the interaction information, which is not specifically limited in this embodiment of the present invention.

In addition, the above content only realizes algorithm selection through a one-way process, that is, one party first determines the algorithm to be used by itself, and informs the other party to select and use the corresponding algorithm through a message. Actually, in the process of implementing the algorithm selection, the algorithm may also be selected through multiple handshake negotiation processes between the base stations and between the base stations and the UE, which is not specifically limited in this embodiment of the present invention.

After determining the first preset algorithm used by the first base station, the first base station may obtain count information corresponding to the count value based on the first preset algorithm. This embodiment of the present invention does not specifically limit the manner in which the first base station operates the count value according to the first preset algorithm to obtain the count information corresponding to the count value, including but not limited to: performing an operation on the count value based on a preset offset Offset operation to get the offset value corresponding to the count value.

For example, take the preset offset of 500 as an example. If the count value is 6, based on the preset offset, an offset operation can be performed on the count value to obtain a corresponding offset value. Taking the offset operation as an addition operation as an example, a corresponding offset value of 506 can be obtained.

It should be noted that, in addition to the above offset operation, the operation process of the first preset algorithm may also be to change the count value into a binary value, and then perform a shift operation on the binary value. Certainly, the operation process of the first preset algorithm may also be an AND or operation with a fixed binary string, and the embodiment of the present invention does not specifically limit the implementation of the first preset algorithm.

After the first base station sends the count information to the second base station or the UE, the second base station or the UE may perform an operation on the count information according to the second preset algorithm to obtain a corresponding count value. Through this process, the count value can be encrypted and/or verified to ensure the security of the count value, and the accuracy of the count value can be verified subsequently.

For example, take downlink data transmission in a handover scenario as an example. If the first preset algorithm is an offset operation and the preset offset is 500, the source base station performs an offset operation on the count value based on the preset offset of 500, and a corresponding offset value of 506 can be obtained. The source base station sends the offset value 506 to the target base station. The target base station side may know in advance that the preset offset is 500. When the offset value received by the target base station is a number less than 500, it can be determined that the count value or the offset value is incorrect, thereby realizing the verification function.

Certainly, in addition to checking the offset value according to the value range of the offset value, other methods may also be used to perform the check, which is not specifically limited in this embodiment of the present invention. In addition, since the above process performs data transformation processing on the count value, that is, the obtained new data is not the original count value, thereby realizing the encryption of the count value, thereby improving the security of the count value in the transmission process.

The above process provides two transmission methods of count value. The first method mainly uses binary bitmap file to represent count information, and then transmits count value by sending binary bitmap file. The second method is mainly to perform an operation on the count value according to the first preset algorithm to obtain corresponding count information, and subsequently transmit the count value by sending the count information. Of course, in addition to the above-mentioned manners, there may also be other transmission manners. Specifically, the embodiment of the present invention does not specifically limit the manner in which the first base station preprocesses the count value according to the first preset manner, and obtains the count information corresponding to the count value, including but not limited to: based on the completion of each transmission confirmation The data transmission result and count value corresponding to the data packet are determined in turn to determine the value of each binary bit to obtain a binary string.

For example, take downlink data transmission in a handover scenario as an example. If the source base station sends 10 data packets to the UE, and the UE has completed the downlink transmission confirmation for these 10 data packets, the count value can be determined to be 11. Take 1 for successful data transmission and 0 for data transmission failure as an example. As the first 10 packets complete the downlink transmission acknowledgment. Therefore, the first 10 data packets can be represented by the following binary string 1111111111.

Since the target base station needs to deliver the 11th data packet to the UE subsequently, and the 11th data packet has not been delivered to the UE, it can correspond to a transmission failure, so the corresponding binary string can be 11111111110.

Wherein, 204, send the count information to the second base station or the UE, so that the second base station or the UE performs data transmission based on the count value.

For downlink data transmission in a handover scenario, the source base station may send the count information to the second base station, and the second base station obtains the count value based on the count information, and then delivers the data packet to the UE based on the count value.

For uplink data transmission in a handover scenario, the source base station may send count information to the UE. Alternatively, the source base station first sends the count information to the target base station, and then the target base station sends the count information to the UE. Alternatively, the count value is obtained by the UE itself, that is, when the UE uploads data to the source base station, the count value is determined based on the upload success confirmation information returned by the source base station. It should be noted that, when the count value is obtained by the UE itself, the process provided by the above steps is not performed. After obtaining the count value, the UE may upload the data packet to the target base station based on the count value.

For downlink data transmission in the DC scenario, the primary base station may send the count information to the secondary base station, and the secondary base station obtains the count value based on the count information, and then delivers a data packet to the UE based on the count value.

For uplink data transmission in the DC scenario, the master base station may send count information to the UE. Or, the primary base station first sends the count information to the secondary base station, and then the secondary base station sends the count information to the UE. Alternatively, the count value is obtained by the UE itself, that is, when the UE uploads data to the master base station, the count value is determined based on the upload success confirmation information returned by the master base station. It should be noted that, when the count value is obtained by the UE itself, the process provided by the above steps is not performed. After obtaining the count value, the UE may upload the data packet to the primary base station or the secondary base station based on the count value.

It should be noted that, when sending the count information, the first base station may send the count information in the form of a data forwarding report, and the embodiment of the present invention does not specifically limit the form of sending the count information. In addition, regarding the channel selected by the first base station to send the count information and the time at which the first base station sends the count information, this embodiment of the present invention also does not specifically limit this.

In the method provided by the embodiment of the present invention, the first base station obtains the count value corresponding to the next data packet of the last data packet for which the transmission confirmation is completed when detecting that the UE establishes a communication connection with the second base station. The count value is communicated to the second base station or UE, so that the second base station or UE performs data transmission based on the count value. Since each data packet is obtained by dividing the data file, after all the divided data packets are sorted in sequence, each data packet corresponds to a count value, that is, the count value corresponding to each data packet is in all divided data packets. The actual sequence number, so that in the process of data state transfer, the corresponding data packet can be uniquely confirmed based on the count value, and the data packet will not be lost or repeated transmission of data packets due to batch determination errors. Therefore, the correct transmission of data can be guaranteed.

In addition, before transmitting the count value, the base station on one side can preprocess the count value to obtain the count information, so that the count value can be encrypted, so as to improve the security in the process of transmitting the count value. When the base station or UE on the other side receives the count information, it may preprocess the count information to check the count value, so as to verify the accuracy of the count value.
