S410: The first terminal device sends a first access request message to the access network device, where the access network device receives the first access request message sent by the first terminal device, where the first access request message is used to request Access to the access network device.

Optionally, the first terminal device may send the first access request message to a control plane node of the access network device, where the control plane node of the access network device receives the first interface sent by the first terminal device Incoming request message.

S420: The access network device sends a first access request response message to the first terminal device, where the first terminal device receives the first access request response message sent by the access network device. The first access request response message is a response to the first access request message. The first access request response message includes configuration information of the first bearer, and the configuration information of the first bearer is used by the first terminal device and the access network device to establish the first bearer. The first bearer is a shared bearer of a plurality of terminal devices including the first terminal device.

Specifically, before the first terminal device sends the uplink data or receives the downlink data, the first terminal request message is sent to the access network device, where the first access request message is used to request access to the access network device, where The access network device replies to the first terminal device with a first access request response message, where the first access request response message includes configuration information of the first bearer, and the configuration information of the first bearer is used by the first terminal device and The user plane node of the access network device establishes the first bearer, and the first bearer is a shared bearer of multiple terminal devices including the first terminal device.

Established after the request response message. The first bearer setup procedure is triggered by an access request message corresponding to the first terminal device.

It should also be understood that when the first terminal device accesses the access network device, there is already the establishment of the first bearer (the previous terminal device access triggers the establishment of the first bearer), then there is no need to re-establish The new bearer directly sends the bearer information of the first bearer to the first terminal device. For example, the access network device sends the ID of the first bearer to the first terminal device.

It should be further understood that after the first terminal device accesses the access network device, the second terminal device sends an access request to the access network device, if the QoS requirements of the first terminal device and the second terminal device are the same or similar Then, it is not necessary to re-establish a new bearer, and directly send the existing information of the first bearer to the second terminal device.

Optionally, the information of the first bearer is an ID of the first bearer.

In the existing system, if data transmission is to be performed between the terminal device and the network (for example, PGW), the end-to-end bearer must be established first, and the bearer is based on the terminal device, that is, different terminal devices are not The same bearer will be shared, and the bearer based on the terminal device means that whenever a new terminal device accesses the network, a new bearer needs to be re-established, and the establishment of the bearer involves the connection between the terminal device and the network device. Signaling interaction causes a certain signaling overhead.

In the transmission method of the embodiment of the present application, different terminal devices can use the same shared bearer for data transmission, which helps to avoid waste of resources in the transmission process, and avoids access in each terminal device. Establishing a separate end-to-end bearer during the network helps save signaling overhead.

After receiving the second access request message, the control plane node of the core network device may process the second access request message, for example, in the The QoS authorization information and the access authentication information are added to the second access request message to obtain the third access request message, and the third access request message is sent to the policy function node of the core network device after the processing.

S412, the core network device sends a second access request response message to the access network device, where the access network device receives a second access request response message sent by the core network device, where the second access request response message is used. The indication is to allow/deny the first terminal device to access the access network device.

It should be understood that the access request response message sent by the core network device to the access network device does not include the information of the first bearer, and the access network device receives the access request response message sent by the core network device. Then, the information of the first bearer may be carried in the access request response message and sent to the first terminal device.

It should be further understood that the first access request response message, the second access request response message, and the third access request response message may be used to indicate that the first terminal device is allowed to be denied access to the access network device, where the The message format of an access request response message, a second access request response message, and a third access request response message may be different.

For example, the temporary terminal device identification information of the first terminal device is 001, and the RLC layer processing is used as an example. When the first terminal device allocates the RLC serial number for the uplink data packet, the following manner can be adopted: 001-001, 001- 002,001-003,... After the second terminal device accesses the access network device, the terminal device identifier information assigned by the access network device to the second terminal device is 002, and the second terminal device separately uses the RLC serial number for the uplink data packet. The following methods can be used: 002-001, 002-002, 002-003, ....

In the transmission method of the embodiment of the present application, the access network device confirms whether to correctly receive a certain data packet according to the identification information of the terminal device allocated by the access network device, and if a certain data packet is lost, may request retransmission from the terminal device, which is helpful. Reduce the data receiving packet loss rate.

S540, the access network device sends the first data to the core network device on a first transmission path, where the core network device receives the first data sent by the access network device on the first transmission path, where The first transmission path is a shared transmission path between the access network device and the core network device, which is at least two terminal devices.

Optionally, the transmission path is a known tunnel between the access network device and the core network device.

Optionally, the user plane node of the access network device sends the first data to the user plane node of the core network device on the first transmission path.

It should be understood that the transmission path between the access network device and the core network device is a node-based transmission path, and before the access network device sends the first data to the core network device, the access network device and At least one transmission path is established between the core network devices.

For example, a transmission path can be established between the access network device and the core network device. This enables data transmission of terminal devices with the same QoS requirements.

For another example, multiple transmission paths can be established between the access network device and the core network device. This enables data transmission of terminal devices with different QoS requirements.

It should be understood that, after receiving the first data sent by the first terminal device, the access network device parses the first data, and when the access network device sends the first data to the core network device, The destination address of a data is the core network device connected to the DN.

It should also be understood that the access network device does not necessarily receive the data of the first terminal device, and it is also possible that the data of the multiple terminal devices are sent to the access network device on the same bearer. Optionally, as shown in FIG. 5, the method further includes:

S501. The access network device establishes at least two transmission paths with the core network device, where the multiple transmission paths include the first transmission path, and each of the multiple transmission paths corresponds to a different quality of service QoS class or network. slice.

Specifically, before the terminal device accesses the network, the network performs initial establishment, and the process mainly includes network activation, configuration of each functional node, and establishment of a transmission path between the access network device and the core network device, for example, the access. The network device is divided into a control plane node and a user plane node. The core network device is divided into a user plane node and a control plane node. During the network initialization process, the control plane node of the access network device and the control plane node of the core network device communicate through signaling. Determining that at least one transmission path is established, and then the control plane node of the access network device and the control plane node of the core network device respectively control the user plane node of the access network device and the user plane node of the core network device, where the access network device is Establishing at least one transmission path between the user plane node and the user plane node of the access network device, where each of the at least one transmission path is at least two between the access network device and the core network device The shared transmission path of the terminal devices.

It should be understood that establishing at least two transmission paths may be performed before the first terminal device sends the first access request message to the access network device, which may save the delay of the data transmission process, and the transmission path is multiple terminal devices. The shared transmission path helps to avoid wasting resources.

It should also be understood that establishing at least two transmission paths may also be performed before the access network device transmits data to the core network device.

It should also be understood that the access network device and the core network device may establish multiple transmission paths according to different QoS categories, and may also establish multiple transmission paths according to network slices. The application is not limited thereto.

Optionally, as shown in FIG. 5, before the sending network device sends the first data to the core network device on the first transmission path, the method 500 further includes:

S531. The access network device selects a first transmission path from the at least two transmission paths, where the first transmission path matches a QoS class or a network slice of the first data.

Optionally, the user plane node of the access network device selects the first transmission path from the at least two transmission paths.

Specifically, after the access network device receives the first data on the first bearer, the access network device needs to have a QoS class or corresponding to the first data, because multiple transmission paths are previously established. The network slice is detected. For example, if the access network device detects that the first one of the plurality of transmission paths matches the QoS class of the first data or the corresponding network slice, the first transmission path is selected, and Transmitting the first data to the core network device on the first transmission path.

It should be understood that the access network device may also establish a mapping relationship between the air interface shared bearer and the transmission path, which may be 1:1 or N:1, and the access network device selects the transmission path according to the mapping relationship between the two. This does not require the inclusion of information about the Qos category in each packet.

For example, there are six shared bearers between the terminal device and the access network device, and there are three transmission paths between the access network device and the core network device, and the access network device can establish a mapping table between the shared bearer and the transmission path. After receiving the uplink data on a shared bearer, the access network device places the uplink data in the corresponding transmission path and sends the uplink data to the core network device. Table 1 shows a shared bearer. The mapping relationship with the transmission path.

Table 1

Shared bearer ID	Corresponding transmission path ID
Bearer 1	Transmission path 1
Bearer 2	Transmission path 1
Host 3	Transmission path 2
Bearer 4	Transmission path 3
Carrying 5	Transmission path 3
Carrying 6	Transmission path 3

It should be further understood that, when the first terminal device receives the downlink data, the core network device sends the downlink data to the access network device on a certain one of the at least one transmission path, where the downlink data carries the first The identification information of the terminal device, the access network device may send the downlink data to the first terminal device in a broadcast or multicast manner, for example, the access network device may be in an independent broadcast/multicast bearer. The terminal device sends the downlink data of the first terminal device, and each of the plurality of terminal devices detects the downlink data, and if the identity information of the terminal device is detected, receives the downlink data; otherwise, the downlink data is discarded. .

Specifically, UE-1 requests access to the network, including access authentication and authorization procedures. The AN-CP includes the shared bearer information, such as the bearer ID, in the first access request response message of the UE-1.

It should be understood that the establishment of the first bearer is triggered by the access of the other terminal device before the access of the UE-1. In this case, the identifier information of the first bearer needs to be carried in the access request response message.

S630. The UE-2 requests to access the network.

The UE-2 requesting access to the network includes:

S720-S726, UE-1 requests access to the network.

S730-S736, UE-2 requests access to the network.
