In this embodiment of the application, after the first terminal determines the target data through the special rule, the first terminal may send the target data through the first interface corresponding to the uplink, so that the network manages the data on the sidelink. For example, data sniffing, billing, data volume statistics, no need to send data to external networks or route within the 5GS, etc. are implemented.

In other words, the first device sends a specific service to the network side.

Assuming that the specific time period is a prescribed period T, the first terminal may report network data at a specific time within the period T, and/or the first terminal may report data of a specific data amount within the period T, such as a specific number of data packets or a specific number of bits (M) or a specific ratio (R), where the specific ratio (R) may be a ratio of data of the reported network to total transmission data or a ratio of data of the PC transmission. When the first terminal reports a specific data volume (M) in the period T, the sending time of the first terminal in the period T may be determined by the terminal or may be configured by the network device.

And assuming that the specific data volume period is a specified data volume period N, reporting a data volume with a data volume M in each data volume period, wherein M is not less than 1,M and is not more than N. Wherein the data of the data volume M belongs to the data of the data volume N. Optionally, the first terminal may report data of a specific data volume in the data volume period N. For example, a specific number of packets or a specific number of bits (M) or a specific ratio (R), where the specific ratio (R) may be a ratio of data of the reporting network to total transmission data or a ratio of data of the PC to transmission data. When the first terminal reports a specific data volume (M) in the period T, the sending time of the first terminal in the period T may be determined by the terminal or may be configured by the network device.

Optionally, when the first terminal has received and/or sent M data through the second interface, N data subsequent to the M data are determined as the target data, where M is greater than or equal to 1, and a ratio of M to N is a specific value.

Taking the second interface as a PC5 interface as an example, the special rule is used to specify that the first terminal needs to report N network data every time M data are transmitted on the PC5 interface, where M and N are not less than 1. Further, the special rule may specify a ratio of M and N

Optionally, the first terminal determines data that has been sent and/or received through the second interface as the target data.

Optionally, the method 200 may further include:

and the first terminal receives the special rule sent by the management equipment.

The management device comprises at least one of a session management function SMF, an access and mobility management function AMF, a policy control function PCF, a network control interworking service NCIS and a service server. Namely, the first terminal receives the special rule sent by at least one of the session management function SMF, the access and mobility management function AMF, and the policy control function PCF.

Specifically, the management device determines a special rule, where the special rule is used for a first terminal to determine target data, where the target data includes data to be sent by the first terminal and/or data that has been sent and/or received through a second interface corresponding to a sidelink of the first terminal; and the management equipment sends the special rule to the first terminal. Optionally, the special rule is specifically used for the first terminal to determine data corresponding to the specific identifier as the target data; the specific identification comprises at least one of the following identifications: the method comprises the steps of source network protocol IP identification, target IP identification, source port identification, target port identification, quality of service (QoS) flow identification, session identification, bearing identification, application identification and service identification. Optionally, the special rule is specifically used for the first terminal to determine the target data in a specific time period or a specific data volume period; the target data comprises data in a specific time segment in each period, and/or the target data comprises a specific amount of data in each period, and/or the target data comprises a specific number of bits of data in each period, and/or the target data comprises a specific proportion of data in each period. Optionally, the special rule is specifically used when the first terminal has received and/or sent M data through the second interface, and determines N data subsequent to the M data as the target data; wherein, M is larger than or equal to 1, and the ratio of M to N is a specific value. Optionally, the special rule is specifically used for the first terminal to determine data that has been sent and/or received through the second interface as the target data.

Taking the management device as an SMF as an example, the special rule may be configured to the first terminal by a network entity SMF in charge of session management when the first terminal applies for session establishment, the network entity SMF in charge of session management obtains a policy (policy) for a specific purpose, such as a policy for lawful interception, from a network entity PCF, and the SMF generates the special rule according to the policy for the specific purpose and a local policy and sends the special rule to the first terminal.

Taking the management device as the NCIS as an example, the special rule may be configured to the first terminal by the NCIS when the first terminal registers. The first terminal applies for registering the NCIS service in the registration process, the network registration management entity NCIS obtains the policy for specific use, such as the policy for legal monitoring, from the network entity PCF, and the NCIS generates the special rule according to the policy for specific use and the local policy and sends the special rule to the first terminal.

Taking the management device as the PCF as an example, the PCF may directly generate the special rule and send the special rule to the first terminal, and specifically may send the special rule to the first terminal through a protocol message, such as an NAS message, between the AMF and the first terminal. I.e. the PCF sends said special rule to said first terminal via the AMF.

It should be understood that the policy provided by the PCF for a specific purpose is not specifically limited by the embodiments of the present application. For example, in some embodiments, different polices may be employed for different sessions/session groups, i.e., the PCF provides the polices for different sessions/session groups, such that the SMF or NCIS generates or determines different rules according to different policies.

Optionally, the method 200 may further include:

and the first terminal sends first indication information to the management device, wherein the first indication information is used for indicating that the target data comprises data received through the second interface and/or data sent through the second interface. In other words, the management apparatus generates and transmits the first indication information to the first terminal. The management device comprises at least one of a session management function SMF, an access and mobility management function AMF, a policy control function PCF, a network control interaction service NCIS and a service server.

Taking the management device as a network entity, the network entity may determine whether to implement the special rule as the sending entity or the receiving entity of the first terminal, and when the special rule is configured for the first terminal, may instruct the sending entity to execute the rule or the receiving entity or both to execute the rule. The network entity may determine the enforcement entity according to a policy provided by the PCF and/or subscription information of the terminal and/or a local policy and/or a policy provided by a third party. Further, the network entity may determine which receiving entities of the terminals implement this rule.

Taking the management device as a core network entity as an example, the core network entity sends the generated rule to an NCIS function management entity or a service server, and the NCIS function management entity or the service server sends the rule to the first terminal through an interface protocol with the first terminal.

Optionally, the special rule is information obtained by the first terminal according to subscription information,

optionally, the special rule is pre-configured information.

The following describes the transmission flow of the target data in detail.

Optionally, as shown in fig. 3, the method 200 may further include:

and S230, the management device sends the target data to the communication device.

The communication equipment receives target data sent by a first terminal through a first interface corresponding to an uplink, wherein the target data comprises data to be sent of the first terminal and/or data sent and/or received through a second interface corresponding to a sidelink of the first terminal; the communication device determines the target data to be data for a particular use.

Optionally, the communication device is a third party entity connected to a user plane function UPF or the communication device is a UPF.

Taking the communication device as the UPF as an example, assume that the second interface is the PC5 and the first interface is the Uu. And the first terminal sends the sent target data to the PC5 and sends the target data to a network side entity UPF through a Uu interface. And after receiving the target data of the first terminal, the UPF transmits the target data to a third party entity. Such as a third party listening entity. At this time, if the third party entity and the UPF are co-located, the UPF does not forward the data.

Since the target data is sent to the UPF for a specific use. For example, data sniffing, billing, data volume statistics, no need to send data to external networks or route within the 5GS, etc. are implemented. Further, by avoiding transmission of the target data to an external network, the security of data can be improved. But also can provide a basis for specific use for the market application of the NCIS service. Therefore, the first terminal needs to indicate the specific use of the target data to the UPF, or the first terminal indicates that the target data is data of a specific use. For example, the communication device needs to receive an indication information, such as a second indication information, which indicates that the target data is data for a specific use.

Optionally, the first indication information may be sent through an air interface PDU.

For example, the first terminal may carry the second indication information in a layer 2 protocol layer in a packet of the target data having a specific purpose. For example, the packet data convergence protocol PDCP PDU and/or the medium access control MAC control element CE of the target data includes the second indication information, and/or the second indication information indicates that the target data is data for a specific purpose through a specific logical channel identity LCID corresponding to the target data. Optionally, the N3 interface protocol data unit PDU of the target data includes the second indication information, and/or a reserved index in a PDU session format of the N3 interface PDU of the target data is used to indicate that the target data is data for a specific purpose.

Optionally, the second indication information may be sent through N3 PDU.

For example, the second indication information is carried in other bits or by adding an indication bit in the N3 PDU.

As shown in fig. 4, N3 PDU may include mapping QoS Indication (RQI), qoS stream identification, session type, remaining bits, and padding bits, which may be indicated by a specific bit in reserved bit byte 1 of N3 PDU, for example, bit 3; a specific bit indication in padding bits may also be used; reserved bits (namely residual bits) can be further adopted to carry the second indication information; a new PDU Session (Session) format may also be indicated, for example, the new PDU Session (Session) format may indicate that the 3 rd or later byte contains the second indication information; the reserved bit of the PDU Type (Type) can also be adopted to carry the second indication information or indicate a new PDU Session format; further, if a new PDU Session format is indicated, the N3 interface protocol data unit PDU of the target data may further include the third indication information, where the third indication information is used to indicate whether the PDU Session format of the target data includes the second indication information.

Optionally, the second indication information indicates that the target data is data for a specific use by at least one of the following: a specific session identification, a Quality of service (QoS) flow identification, and a specific network protocol IP address; the particular IP address includes a particular source IP address and/or a particular destination IP address.

Taking a specific Session identifier or a specific QoS flow identifier as an example, the network configures a specific Session identifier (Session ID) or a specific QoS flow identifier for the data for a specific purpose, and when the UPF detects the data of the specific Session or QoS flow transmitted by the first terminal, the data is considered as the data for the specific purpose.

Taking a specific network protocol IP address as an example, the network configures a specific IP address for the session for the specific purpose, and the first terminal indicates data for the specific purpose using the specific IP address. And when the UPF detects the data of the specific IP address sent by the first terminal, the data is regarded as the data of the specific purpose. Alternatively, the specific IP address is unique within a session and may be the same for different sessions or different terminals.

Optionally, a protocol data unit PDU between the protocol layers between the first terminal and the UPF includes a specific domain, and the specific domain includes the second indication information. I.e. adding a specific indication field in the protocol layer PDU between the first terminal and the UPF. For example, a specific indication field is inserted in the IP header.

Optionally, the communication device is any one of a network control interaction service NCIS, a traffic server and a third party entity.

Taking the NCIS as an example, that is, the first terminal sends the target data to a network, the network sends the target data to a service server or an NCIS functional entity, and the service server or the NCIS functional entity sends the data to a third party entity. Such as a third party listening entity. At this point, if the third party entity and NCIS are co-located, the NCIS does not forward this data.

Since the target data is sent to the NCIS for a specific use. For example, data sniffing, billing, data volume statistics, no need to send data to external networks or route within the 5GS, etc. are implemented. Further, by avoiding transmission of the target data to an external network, the security of data can be improved. But also can provide a basis for specific use for the market application of the NCIS service. Therefore, the first terminal needs to indicate the specific use of the target data to the NCIS, or the first terminal indicates that the target data is data of a specific use. For example, the communication device needs to receive an indication information, such as a fourth indication information, which indicates that the target data is data for a specific purpose.

That is, the first terminal carries the fourth indication information in the data sent to the service server or the NCIS functional entity to notify the service server or the NCIS functional entity that the target data is data for a specific purpose, for example, for network monitoring. When the specific-purpose entity is combined with an entity in a core network, the service server or the NCIS functional entity determines that the target data is the specific-purpose data according to the fourth indication information.

Optionally, the target data includes the fourth indication information, and/or the fourth indication information indicates that the target data is data for a specific use through a specific channel, where the specific channel includes an application server and a channel of any one of the following: the NCIS, the service server and the third party entity; the specific channel comprises a specific network protocol IP channel and/or a specific communication packet wireless service user plane tunneling protocol GTP-U.

In the above description, for the specific implementation manner that the first terminal sends the target data through the first interface, the wireless communication method of the first terminal is described in detail below with reference to the second terminal.

Optionally, the first terminal is provided with a reordering function between an application layer and a network protocol IP layer; the first terminal sends the target data to the second terminal only through the first interface in a reordering mode. The second terminal is provided with a reordering function between an application layer and a network protocol IP layer; and the second terminal re-orders and receives the target data sent by the first terminal only through the first interface.

When the first terminal determines to transmit data on the Uu interface, duplicate data is not transmitted on the PC5 interface, and it is necessary to deliver the received data to the application layer after reordering the data on the receiving terminal side. The implementation manner of this embodiment is adapted to the routing manner in which the core network sends data to the application server when the Uu interface data is transmitted. As shown in fig. 5. Particular embodiments may add a new layer between the sending terminal and the receiving terminal for handling the sequencing function.

Taking the TCP protocol as an example, assume that the second interface is PC5 and the first interface is Uu. In the Multi-Path TCP (MPTCP) protocol, a reordering mechanism exists. When the transmitting terminal needs to transmit data to the network side for a specific use, the transmitting terminal stops transmitting data on the PC5 interface. Specifically, the sending terminal encapsulates the data into a Uu interface. After the data for the specific use is not required to be transmitted, the transmitting terminal transmits the data on the PC 5. When the receiving terminal receives the data, the data from the Uu interface and the data from the PC5 interface can arrive out of order, and the MPTCP layer of the receiving terminal executes a reordering function to ensure that the data are delivered to an application layer in order. It should be understood that the transmitting terminal may be any one of the first terminal and the second terminal shown in fig. 5. Any terminal can comprise AN application layer, AN MPTCP layer, AN IP layer and a 5G Access Network (AN) protocol layer from top to bottom.

The second terminal is provided with a repeated detection function between an application layer and a network protocol IP layer; and the second terminal repeatedly detects and receives the target data sent by the first terminal through the first interface and the second interface.

Assume that the second interface is PC5 and the first interface is Uu. And a repeat detection function is added between the sending terminal and the receiving terminal, and the data of the Uu interface is sent to the application server. When the sending terminal needs to send data to the network side, the sending terminal sends the data at both the Uu interface and the PC5 interface, and the sending terminal and the receiving terminal are added with a data repetition detection mechanism. This embodiment is suitable for forwarding data sent to the Uu interface to the application server via the core network, as shown in fig. 6, where the duplicate detection mechanism is located above the IP layer. When the transmitting terminal transmits data, information for repeated data detection, such as data serial numbers, is added to the duplicate detection layer, and data aiming at the same data serial number are respectively packaged to be transmitted on the Uu interface and the PC5 interface in the IP layer. After the receiving terminal repeatedly detects the received data of the bottom layer, the data serial number in the data is extracted, the data with the repeated serial number is abandoned, and the data is delivered to the high layer. It should be understood that the transmitting terminal may be any one of the first terminal and the second terminal shown in fig. 6.

Optionally, the first terminal is provided with a reordering function and a duplicate detection function between a packet data convergence protocol PDCP layer and a network protocol IP layer; and the first terminal sends the target data to the second terminal through the first interface and the second interface in a reordering and repeated detection mode.

Assume that the second interface is PC5 and the first interface is Uu. And a repeat detection function is added between the sending terminal and the receiving terminal, and the data of the Uu interface is not sent to the application server. This embodiment is suitable for data sent to the Uu interface not being sent to the application server, the data being sent to the receiving terminal over the 3GPP network internal path. As shown in fig. 7, in order to implement a reordering and duplicate detection mechanism at a receiving terminal, one embodiment is to add a new layer between the PDCP and IP layers for implementing the functions of reordering and duplicate detection. The specific implementation mode is that sequence numbers are added to the same IP packet in the new layer, reordering and repeated detection are carried out on SN numbers of data received from the PC5 interface and the Uu interface in the peer layer of the receiving terminal, and the data are delivered to the higher layer.
