Fig. 2 is a flow chart of a data connection establishment method provided in an embodiment of the present application, which is applied to a first network functional entity, as shown in fig. 2, and the data connection establishment method includes the following steps:

step 201, a first network function entity sends a first data connection establishment request to a target device, where the first data connection establishment request is used to request the target device to establish a target data connection with the first network function entity, and the first data connection establishment request includes type or requirement information of the data connection, where the target device includes one of the following: the target data connection is used for sending target data to the first network function by the target equipment.

Wherein the first network function entity may be a dedicated data plane function (Data Plane Function, DPF), the DPF being used for establishing the data connection; the second network functional entity may be a core network device, such as an AMF or SMF; when the target device is an access network device or a second network function entity, the target data access network device or the second network function entity required by the first network function entity can be provided without acquisition from the terminal.

The first network function entity may receive a data request message sent by the data requester, determine type or requirement information of the data connection based on content carried in the data request message, and then carry the type or requirement information of the data connection in the first data connection request, and send a first data connection establishment request for requesting establishment of a target data connection between the target device and the first network function entity to the target device; the first network function entity may also negotiate type or demand information of the data connection with the data requester in advance, and negotiate time of establishing the data connection, and send a first data connection establishment request for requesting to establish the target data connection between the target device and the first network function entity to the target device based on the negotiated time of establishing the data connection, where the first data connection establishment request includes the type or demand information of the data connection.

When the target device is the second network function entity, the second network function entity may establish a target data connection between the second network function entity and the first network function entity based on the first data connection establishment request when receiving the first data connection establishment request, and send target data (may be data of a terminal pre-stored in the second network function entity) to the first network function entity based on the target data connection, and the first network function entity forwards the target data to the data demander.

When the target device is an access network device, the access network device may establish a target data connection between the access network device and the first network function entity based on the first data connection establishment request when receiving the first data connection establishment request, and send target data (may be data of a terminal pre-stored in the access network device) to the first network function entity based on the target data connection, and the first network function entity forwards the target data to a data demander.

When the target device is a terminal, the terminal may establish a target data connection between the terminal and the first network function entity based on the first data connection establishment request when receiving the first data connection establishment request, and send target data to the first network function entity based on the target data connection, and the first network function entity forwards the target data to the data demander.

According to the data connection establishment method provided by the embodiment of the invention, the first network function entity can send the first data connection establishment request comprising the type or the requirement information of the data connection to the terminal, the access network device or the second network function entity, so that the terminal, the access network device or the second network function entity can establish the target data connection with the first network function entity based on the type or the requirement information of the data connection included in the first data connection establishment request, and thus the target data can be sent to the first network function entity on the established target data connection, and the data collection between the first network function entity and the second network function entity, between the first network function entity and the access network device and between the first network function entity and the terminal based on the type or the requirement information of the data connection can be realized, and the data connection of different data connection types can be supported.

Optionally, fig. 3 is a second flowchart of a data connection establishment method according to an embodiment of the present application, as shown in fig. 3, before step 201, the data connection establishment method further includes the following steps:

step 202, the first network function entity receives a data request message, where the data request message is used to request target data from the first network function entity, and the data request message includes at least one of the following information: anonymization requirements, data granularity requirements, and real-time requirements.

Wherein the anonymization requirement includes one of the following information: an anonymity requirement for the terminal or user, a semi-anonymity requirement for the terminal or user, and a non-anonymity requirement for the terminal or user; the data granularity requirement includes one of the following information: a requirement with granularity of a single terminal, a requirement with granularity of a terminal group, a requirement with granularity of a region and a requirement with granularity of a network element; the real-time requirements include one of the following information: the real-time acquisition requirement of the target data, the quasi-real-time acquisition requirement of the target data and the non-real-time acquisition requirement of the target data.

Anonymity refers to that the access network equipment, the first network functional entity and the second network functional entity do not know identity information of a terminal or a user; semi-anonymity means that the access network device and the second network function entity can know identity information of the terminal or the user, but the first network function entity does not know the identity information of the terminal or the user; non-anonymous means that at least one of the access network device, the first network function entity, and the second network function entity knows identity information of the terminal or the user. Taking a single terminal as granularity means that target data of a specific terminal is acquired; taking the terminal group as granularity means that target data of all terminals in a certain group are acquired; taking the region as granularity means that target data of all terminals in a certain region are acquired; taking the network element as granularity refers to acquiring target data of all terminals in a certain network element or acquiring data of the network element itself, such as network element load and the like. Acquiring data in real time is to acquire the data in a first preset time or less; quasi-real-time acquisition refers to acquiring data in a time period greater than a first preset time and less than or equal to a second preset time period; the non-real-time acquisition refers to acquiring data after more than a second preset time or acquiring data based on a specific duration.

Illustratively, the first network function entity receives a data request message sent by a data requester, the data request message being for requesting target data from the first network function entity; the data request message may carry at least one of anonymization requirements, data granularity requirements, and real-time requirements; in addition, the data requester may be other network function entities in the core network, for example, NWDAF, and if the NWDAF performs big data analysis on the collected data, the NWDAF may send a data request message for requesting the target data used for big data analysis to the first network function entity; the data requester may also be an external third party network function, such as a service server or the like.

Step 203, the first network function entity determines the type of the data connection or the requirement information based on the data request message.

Wherein, in case the anonymized demand is included in the data request message, the type of data connection or demand information includes one of: anonymous connections, semi-anonymous connections, and non-anonymous connections; and/or the number of the groups of groups,

in the case that the data granularity requirement is included in the data request message, the type or requirement information of the data connection includes connection of a specific terminal or connection of a non-specific terminal; and/or the number of the groups of groups,

In the case that the real-time requirements are included in the data request message, the type of data connection or the requirement information includes one of the following: control plane based connections, user plane based connections, data plane based connections.

The control plane connection is used for reporting the target data in a control plane signaling mode, and the user name connection is used for reporting the target data in a user plane session path mode.

Illustratively, when the first network functional entity receives the data request message, the type of the data connection or the requirement information may be determined based on the data requirement (at least one of anonymization requirement, data granularity requirement and real-time requirement) carried in the data request message; for example, if the data requirement carried in the data request message is an anonymization requirement, the type of the data connection or the requirement information is an anonymization connection; if the data requirement is a semi-anonymization requirement, the type or the requirement information of the data connection is a semi-anonymization connection; if the data requirement is a non-anonymization requirement, the type or the requirement information of the data connection is a non-anonymization connection; if the data requirement is a real-time acquisition requirement, the type of the data connection or the requirement information is connection based on a control plane; if the data requirement is a quasi-real-time acquisition requirement or a non-real-time acquisition requirement, the type or the requirement information of the data connection is a connection based on a user plane or a connection based on a data plane, and the data connection can be specifically determined through negotiation; if the data requirement is a requirement with single terminal as granularity, the type of data connection or the requirement information is the connection of the specific terminal; if the data requirement is a requirement with granularity of terminal group, a requirement with granularity of region, or a requirement with granularity of network element, the type of data connection or requirement information is connection of non-specific terminal.

It should be noted that, when the target data connection is established, the type or the requirement information of the data connection may be determined based on the anonymization requirement, the data granularity requirement and the real-time requirement, for example, the type or the requirement information of the data connection includes an anonymized connection, a specific terminal connection and a connection based on a control plane. The determination may also be made based on two of anonymization requirements, data granularity requirements, and real-time requirements, e.g., the type of data connection or the requirement information includes an anonymous connection and a control plane based connection; specifically, the content of the data requirement carried in the data request message may be determined, which is not limited in this application.

When the target data connection is based on the user plane connection, the terminal sends the target data to the first network functional entity through the access network device and the user plane function (User Plane Function, UPF) in sequence when the target device is the terminal; and under the condition that the target equipment is access network equipment, the access network equipment sends target data to the first network functional entity through UPF.

According to the data connection establishment method, the first network function entity determines the type or the requirement information of the data connection based on at least one of anonymization requirements, data granularity requirements and real-time requirements carried in the data request message, so that target equipment can conveniently establish target data connection with the first network function entity based on the type or the requirement information of the data connection, different requirements on whether target data is anonymized, whether real-time performance is achieved or not are met, and flexibility of data collection is improved.

Optionally, fig. 4 is a third flowchart of the data connection establishment method according to the embodiment of the present application, as shown in fig. 4, after the step 201, the data connection establishment method further includes the following steps:

step 204, the first network function entity receives the target data sent by the target device on an established reference data connection, where the reference data connection is established by the target device based on the type or requirement information of the data connection.

Specifically, based on different target devices, the established reference data connection is different, and the manner in which the first network functional entity receives the target data is also different, which is specifically as follows:

in the case that the target device comprises a terminal, the reference data connection comprises a first data connection between the terminal and the access network device, the target data connection comprising the first data connection and a second data connection between the access network device and the first network function entity; alternatively, the target data connection comprises the first data connection, a third data connection between the access network device and the second network function entity, and a fourth data connection between the second network function entity and the first network function entity. That is, the reference data connection is only the first data connection in the target data connection.

The first network functional entity receives the target data sent by the terminal on the first data connection through the second network functional entity and the access network equipment; or,

the first network functional entity receives the target data sent by the terminal on the first data connection through the access network equipment.

When the target device is a terminal, the terminal may establish a reference data connection between the terminal and the access network device based on the type or the requirement information of the data connection carried in the first data connection establishment request, that is, the first data connection, when the terminal receives the first data connection establishment request, and the access network device establishes a second data connection between the access network device and the first network functional entity based on the type or the requirement information of the data connection, where the first data connection and the second data connection form the target data connection; or the access network equipment establishes a third data connection between the access network equipment and the second network functional entity based on the type or the requirement information of the data connection, then the second network functional entity establishes a fourth data connection between the second network functional entity and the first network functional entity based on the type or the requirement information of the data connection, and the first data connection, the third data connection and the fourth data connection form a target data connection.

In the case that the target device comprises an access network device, the reference data connection comprises a second data connection between the access network device and the first network function entity, or a third data connection between the access network device and the second network function entity;

the target data connection includes the second data connection; alternatively, the target data connection comprises the third data connection and a fourth data connection between the second network function entity and the first network function entity; that is, the reference data connection is the second data connection in the target data connection or the third data connection in the target data connection.

The first network functional entity receives the target data sent by the access network device on the third data connection through the second network functional entity; or,

the first network function entity receives the target data sent by the access network device over the second data connection.

When the target device is an access network device, the access network device may establish a second data connection between the access network device and the first network functional entity based on the type or the requirement information of the data connection carried in the first data connection establishment request when receiving the first data connection establishment request, where the second data connection is the target data connection; or the access network equipment establishes a third data connection between the access network equipment and the second network functional entity based on the type or the requirement information of the data connection, then the second network functional entity establishes a fourth data connection between the second network functional entity and the first network functional entity based on the type or the requirement information of the data connection, and the third data connection and the fourth data connection form a target data connection.

In the case that the target device comprises a second network function entity, the reference data connection comprises a fourth data connection between the second network function entity and the first network function entity; the target data connection includes the fourth data connection; that is, the reference data connection is the fourth data connection in the target data connection.

The first network function receives the target data sent by the second network function entity over the fourth data connection.

For example, when the target device is the second network function entity, the second network function entity may establish a fourth data connection between the second network function entity and the first network function entity based on the type or the requirement information of the data connection carried in the first data connection establishment request when receiving the first data connection establishment request, where the fourth data connection is the target data connection.

According to the data connection establishment method provided by the embodiment of the application, different target data connections are correspondingly established based on different target devices, so that data transmitted on the corresponding target data connections between the first network function entity and the second network function entity, between the first network function entity and the access network device and between the first network function entity and the terminal are collected.

Optionally, in case the type or requirement information of the data connection comprises the non-anonymous connection, the identity information of the terminal or user is included in the target data sent over at least one of the following data connections: a first data connection, a second data connection, a third data connection, and a fourth data connection;

in case the type or requirement information of the data connection comprises the anonymous connection, identity information of the terminal or user is not included in the target data sent over at least one of the following data connections: a first data connection, a second data connection, a third data connection, and a fourth data connection;

in case the type or requirement information of the data connection comprises the semi-anonymous connection, the identity information of the terminal or user may be included in the target data sent on the first data connection or the third data connection; the identity information of the terminal or the user is not included in the target data sent on the second data connection or the fourth data connection;

in case the type or requirement information of the data connection comprises the semi-anonymous connection, the identity information of the terminal or user, or the temporary identification information of the terminal or user, is included in the target data sent on the first data connection; the target data sent on the third data connection comprises the identity information of the terminal or the user, and the target data sent on the second data connection or the fourth data connection comprises the temporary identification information of the terminal; the temporary identification information and the identity information have a corresponding relationship.

Optionally, in case the type or requirement information of the data connection comprises the anonymous connection, at least one of the following data connections comprises a common tunnel: a first data connection, a second data connection, a third data connection, and a fourth data connection.

The identity information of the terminal or the user may be globally unique identity information, for example, the identity information of the terminal may be an international mobile equipment identity (International Mobile Equipment Identity, IMEI), the identity information of the user may be a user permanent identifier (Subscription Permanent Identifier, SUPI) or an international mobile subscriber identity (International Mobile Subscriber Identity, IMSI) and the like, the temporary identity information may be a Cell radio network temporary identity (Cell-Radio Network Temporary Identifier, C-RNTI), or a 5G globally unique temporary UE identity (5G Globally Unique Temporary UE Identity,5G-GUTI) and the like, and the correspondence between the temporary identity information and the identity information may be stored in the access network device or the second network functional entity.

For example, in case the type of data connection or the requirement information comprises a non-anonymous connection and the target device is a terminal, if the target data connection consists of a first data connection and a second data connection, both the first data connection and the second data connection may comprise identity information of the terminal or the user; if the target data connection consists of a first data connection, a third data connection and a fourth data connection, the first data connection, the third data connection and the fourth data connection may each comprise identity information of the terminal or the user.

In case the type or requirement information of the data connection comprises a non-anonymous connection and the target device is a second network function entity, the target data connection consists of a fourth data connection, which then comprises identity information of the terminal or user.

For example, in case the type of data connection or the requirement information comprises an anonymous connection and the target device is a terminal, if the target data connection consists of a first data connection and a second data connection, neither the first data connection nor the second data connection comprises identity information of the terminal or the user; if the target data connection consists of a first data connection, a third data connection and a fourth data connection, none of the first data connection, the third data connection and the fourth data connection comprises identity information of the terminal or the user. If the target data connection consists of a second data connection, the second data connection does not comprise identity information of the terminal or the user, in case the type or the requirement information of the data connection comprises an anonymous connection and the target device is an access network device; if the target data connection consists of a third data connection and a fourth data connection, neither the third data connection nor the fourth data connection comprises identity information of the terminal or the user. In case the type or requirement information of the data connection comprises an anonymous connection and the target device is a second network function entity, the target data connection consists of a fourth data connection, the fourth data connection does not comprise identity information of the terminal or the user.

For example, in the case where the type of data connection or the requirement information includes an anonymous connection and the target device is a terminal, if the target data connection is composed of a first data connection and a second data connection, both the first data connection and the second data connection may be a common tunnel; if the target data connection is made up of a first data connection, a third data connection and a fourth data connection, the first data connection, the third data connection and the fourth data connection may all be a common tunnel. In case the type or requirement information of the data connection comprises an anonymous connection and the target device is an access network device, the second data connection may be a public tunnel if the target data connection consists of the second data connection; if the target data connection consists of a third data connection and a fourth data connection, both the third data connection and the fourth data connection may be a common tunnel. In case the type or requirement information of the data connection comprises an anonymous connection and the target device is a second network function entity, the target data connection consists of a fourth data connection, then the fourth data connection may be a public tunnel. The identity information of the terminal or the user is transmitted on the public tunnel, and the access network device, the second network function entity and the first network function entity cannot acquire the identity information of the terminal or the user.

In the case that the type or requirement information of the data connection comprises semi-anonymous connection and the target device is a terminal, if the target data connection is composed of a first data connection and a second data connection, the first data connection may comprise identity information of the terminal or the user, and the second data connection does not comprise identity information of the terminal or the user; if the target data connection consists of a first data connection, a third data connection and a fourth data connection, the first data connection or the third data connection may comprise identity information of the terminal or the user, and the fourth data connection does not comprise identity information of the terminal or the user. In case the type or requirement information of the data connection comprises a semi-anonymous connection and the target device is an access network device, if the target data connection consists of a second data connection, the second data connection does not comprise identity information of the terminal or the user; if the target data connection consists of a third data connection and a fourth data connection, the third data connection may comprise identity information of the terminal or the user, and the fourth data connection does not comprise identity information of the terminal or the user. In case the type or requirement information of the data connection comprises a semi-anonymous connection and the target device is a second network function entity, the target data connection consists of a fourth data connection, which does not comprise identity information of the terminal or the user.

If the target data connection is composed of a first data connection and a second data connection, the target data sent on the first data connection may include identity information of the terminal or the user, or temporary identification information of the terminal or the user, and the target data sent on the second data connection does not include identity information of the terminal or the user, or temporary identification information of the terminal or the user; if the target data connection is composed of the first data connection, the third data connection and the fourth data connection, the target data sent on the first data connection or the third data connection may include identity information of the terminal or the user, or temporary identification information of the terminal or the user, and the target data sent on the fourth data connection does not include identity information of the terminal or the user, or temporary identification information of the terminal or the user. If the target data connection is composed of a second data connection, the identity information of the terminal or the user is not included in the target data sent on the second data connection under the condition that the type or the requirement information of the data connection comprises semi-anonymous connection and the target device is access network equipment; if the target data connection is composed of the third data connection and the fourth data connection, the target data sent on the third data connection may include identity information of the terminal or the user, or temporary identification information of the terminal or the user, and the target data sent on the fourth data connection does not include identity information of the terminal or the user, or temporary identification information of the terminal or the user.

It should be noted that, when the identity information of the terminal or the user is included, the identity information of the terminal or the user may also be encrypted.

It should be noted that, when only the temporary identifier information of the terminal or the user is carried in the first data connection, the access network device or the second network functional entity may convert the temporary identifier information into the identity information and store the identity information based on the corresponding relationship between the stored temporary identifier information and the identity information, but when the connection is anonymous or semi-anonymous, the converted identity information cannot be revealed to the first network functional entity.
