s410, the first terminal equipment sends a first access request message to the access network equipment, and the access network equipment receives the first access request message sent by the first terminal equipment, wherein the first access request message is used for requesting to access the access network equipment.

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 access request message sent by the first terminal device.

S420, the access network device sends a first access request response message to the first terminal device, and 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 a first bearer, where the configuration information of the first bearer is used for 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 uplink data or receives downlink data, a first access request message is sent to an access network device, where the first access request message is used to request access to the access network device, the access network device replies a first access request response message to the first terminal device, where the first access request response message includes configuration information of a first bearer, where the configuration information of the first bearer is used to establish the first bearer between the first terminal device and a user plane node of the access network device, and the first bearer is a shared bearer of multiple terminal devices including the first terminal device.

It should be understood that when the first terminal device accesses the access network device, no air interface bearer is established before, and then the access request response message carries configuration information for establishing the first bearer, where the first bearer is established after the access request response message. The access request message corresponding to the first terminal device triggers the first bearer establishment procedure.

It should also be understood that when the first terminal device accesses the access network device, the first bearer is already established (when other terminal devices access triggers the establishment of the first bearer, then a new bearer is not required to be re-established, and the existing bearer information of the first bearer is directly sent 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 also be 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, and if the QoS requirements of the first terminal device and the second terminal device are the same or similar, then a new bearer is not required to be re-established, and the information of the existing first bearer is directly sent 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), an end-to-end bearer must be established first, where the bearers are based on the terminal device, that is, different terminal devices do not share the same bearer, 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 signaling interaction between the terminal device and the network device, resulting in a certain signaling overhead.

According to the transmission method provided by the embodiment of the application, through the establishment of the shared bearer, different terminal equipment can use the same shared bearer to carry out data transmission, so that resource waste in the transmission process is avoided, and meanwhile, the establishment of a separate end-to-end bearer when each terminal equipment is accessed to a network is avoided, and signaling overhead is saved.

It should be understood that the first access request message, the second access request message, and the third access request message may be used to request (the first terminal device) to access to the access network device, where message formats of the first access request message and the second access request message may be different, and 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, add Qos authorization information and access authentication information to the second access request message, to obtain the third access request message, and send the third access request message to the policy function node of the core network device after processing.

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

Optionally, the policy function node of the core network device sends a third access request response message to the control plane node of the core network device, the control plane node of the core network device receives the policy function node of the core network device and sends the third access request response message, the control plane node of the core network device sends the second access request response message to the control plane node of the access network device, and the control plane node of the access network device receives the control plane node of the core network device and sends the second access request response message.

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 after the access network device receives the access request response message sent by the core network device, the access network device may send the information of the first bearer to the first terminal device with the information of the first bearer carried in the access request response message.

It should also be appreciated that the first, second and third access request response messages may be used to indicate that the first terminal device is allowed/denied access to the access network device, and that the message formats of the first, second and third access request response messages may be different.

It should also be appreciated that the first access request response message, the second access request response message and the third access request response message may also be used to instruct the first terminal device how to access the access network device.

For example, the temporary terminal equipment identification information of the first terminal equipment is 001, and for example, RLC layer processing, when the first terminal equipment allocates an RLC sequence number to an uplink data packet, the following manner may be adopted: 001-001, 001-002, 001-003, …. When the second terminal device accesses the access network device, the access network device assigns 002 terminal device identification information to the second terminal device, and when the second terminal device is RLC sequence numbers of uplink data packets, the following manner may be adopted: 002-001, 002-002, 002-003, ….

According to the transmission method provided by the embodiment of the application, the access network equipment confirms whether a certain data packet is correctly received according to the identification information of the terminal equipment distributed by the access network equipment, and if the certain data packet is lost, the retransmission can be requested to the terminal equipment, so that the data receiving packet loss rate can be reduced.

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

Optionally, the transmission path is a tunnel known 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 a first transmission path.

It will be appreciated that the transmission path between the access network device and the core network device is a node-based transmission path, and that at least one transmission path may be established between the access network device and the core network device before the access network device sends the first data to the core network device.

For example, a transmission path may be established between the access network device and the core network device. This may enable data transmission for terminal devices having the same QoS requirements.

As another example, multiple transmission paths may be established between the access network device and the core network device. This allows for data transmission for terminal devices with different Qos requirements.

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

It should also be understood that the access network device does not necessarily have to receive only the data of the first terminal device, but it is also possible that the data of a plurality of 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 transmission path in the multiple transmission paths corresponds to a different QoS class or network slice.

Optionally, the control plane node of the access network device controls the user plane node of the access network device, the control plane node of the core network device controls the user plane node of the core network device, and at least two transmission paths are established between the user plane node of the access network device and the user plane node of the core network device.

Specifically, before the terminal device accesses the network, the network will perform initialization establishment, 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 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 determine to establish at least one transmission path through signaling interaction, 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, at least one transmission path is established between the user plane node of the access network device and the user plane node of the access network device, and each transmission path in the at least one transmission path is a shared transmission path between the access network device and the core network device and the at least two terminal devices.

It should be understood that the establishment of 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 time delay in the data transmission process, and the transmission paths are shared transmission paths of multiple terminal devices, so as to help avoid resource waste.

It should also be appreciated that the establishment of at least two transmission paths may also take place before the access network device sends 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 classes, and may also establish multiple transmission paths according to network slices, and the application is not limited thereto.

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

and S531, the access network equipment selects a first transmission path from the at least two transmission paths, wherein the first transmission path is matched with the QoS class or the 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, since a plurality of transmission paths are previously established, the access network device needs to detect a QoS class or a corresponding network slice of the first data at this time, for example, if the access network device detects that a first transmission path in the plurality of transmission paths matches the QoS class or the corresponding network slice of the first data, the access network device selects the first transmission path and sends 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, may also be N: and 1, the access network equipment selects a transmission path according to the mapping relation of the two data packets, so that each data packet does not need to contain Qos class information.

For example, 6 shared bearers exist between the terminal device and the access network device, 3 transmission paths exist between the access network device and the core network device, the access network device may establish a mapping table between the shared bearers and the transmission paths, and after the access network device receives uplink data on a certain shared bearer, the uplink data is placed in a corresponding transmission path through the mapping table and sent to the core network device, where table 1 shows a mapping relationship between the shared bearer and the transmission path.

TABLE 1

Shared bearer ID	Corresponding transmission path ID
		Bearing 1	Transmission path 1
Carrier 2	Transmission path 1
		Bearing 3	Transmission path 2
Load bearing 4	Transmission path 3
		Load bearing 5	Transmission path 3
Load bearing 6	Transmission path 3

It should also be understood that, when the first terminal device receives downlink data, the core network device sends the downlink data to the access network device on a certain transmission path in at least one transmission path, where the downlink data carries identification information of the first terminal device, and 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 send the downlink data of the first terminal device to multiple terminal devices on independent broadcast/multicast bearers, where each terminal device in the multiple terminal devices detects the downlink data, and if the own identification information is detected, then receives the downlink data; otherwise, the downstream data is discarded.

The transmission method of the embodiment of the application is beneficial to avoiding resource waste and saving signaling overhead in the data transmission process by establishing at least one transmission path between the access network equipment and the core network equipment, and is beneficial to saving time delay in the transmission process by establishing the at least one transmission path before the terminal equipment accesses the network.

It should be understood that the UE-1 access has been preceded by other terminal device accesses triggering the establishment of the first bearer, and only the identification information of the first bearer needs to be carried in the access request response message.
