The core network device or node may be, for example, a User plane function (User PlaneFunction, UPF) or the like.
The method for transmitting the service provided by the embodiment of the application is described in detail below through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
As shown in fig. 2, one embodiment of the present application provides a method 200 of traffic transmission, which may be performed by a network device, in other words, by software or hardware installed in the network device, which may be a base station, the method comprising the steps of:
s202: and receiving the target service sent by the core network equipment through the unicast service channel.
The core network node may transmit the target traffic to the base station using a unicast transmission channel. For example, the core network node user plane function (User Plane Function, UPF) sends traffic TMGI-1 with a temporary mobile group identifier (Temporary Mobile Group Identifier, TMGI) of 1 to the gNB via GTP-U Tunnel and quality of service flow (Quality of Service flow, qoS flow). The base station can receive the target service sent by the core network device through the unicast service channel.
S204: and transmitting the target service borne by the unicast service channel to the terminal equipment through the multicast service channel.
In general, after the base station receives the target service sent by the core network device through the unicast service channel, the target service is also sent to the UE through the unicast service channel, but transmission resources may be wasted due to the need to establish multiple unicast transmission channels. However, through this step, the base station may send the target traffic carried by a plurality of the unicast traffic channels to the terminal device through the multicast traffic channel, thereby avoiding waste of transmission resources compared with sending the same traffic to the UE through the unicast transmission channel.
As shown in fig. 3, one embodiment of the present invention provides a method 300 of traffic transmission, which may be performed by a network device, in other words, by software or hardware installed in the network device, which may be a base station, the method comprising the steps of:
s302: and receiving the target service sent by the core network equipment through the unicast service channel.
The same descriptions as those of step S202 in the embodiment of fig. 2 are adopted in this step, and are not repeated here.
S303: and receiving service information of the target service and/or identification of a unicast transmission channel sent by the core network equipment.

In one implementation, the service information of the target service includes at least one of the following information: service identification, service name, service interpretation, service transmission address, service transmission protocol, session identification and service type indication.
In particular, the service identifier may be, for example, a TMGI, the service name may be, for example, a central television station, the service explanation may be, for example, a multicast service distribution channel, such as a central television station program transmitted through a broadcast television network, and the multicast service feature may be, for example, voice or video. The sending address of the service may be, for example, a TCP and/or IP address, and a sending port number corresponding to the address, the sending protocol of the service may be, for example, HTTP (Hypertext Transport Protocol, hypertext transfer protocol), or SMTP (Simple MessageTransfer Protocol ), the session identifier may be, for example, MBS session-1), and the service type indication may be, for example, multicast service or unicast service.
In one implementation, the identification of the unicast transmission channel includes: at least one of a transport tunnel identification, a session identification, and a data flow identification. Specifically, the transport tunnel identifier may be, for example, GTP-UTunel-1, the Session identifier may be, for example, PDU Session-1, and the data flow identifier may be, for example, qoS flow-1.
S304: and under the condition that the target service meets the preset condition, transmitting the target service borne by the unicast service channels to the terminal equipment through the multicast service channel.
Wherein, the preset conditions include: the service information corresponding to the target service carried by the unicast transmission channels is the same, or the data volume of the target service carried by the unicast transmission channels exceeds a threshold value.
In one implementation manner, the base station may determine, according to the service information received in the previous step, whether service information corresponding to the target service carried by the plurality of unicast transmission channels is the same, and send, in case that service information corresponding to the target service carried by the plurality of unicast transmission channels is the same, the target service carried by the plurality of unicast service channels to the terminal device through the multicast service channel. Otherwise, under the condition that service information corresponding to the target service carried by the unicast service channels is different, the target service carried by the unicast service channels is sent to the terminal equipment through the multicast service channel.
In another implementation manner, the base station may determine the data amount of the target service carried by the unicast transmission channels according to the identifier of the unicast transmission channel received in the previous step, and if the data amount of the target service carried by the unicast transmission channels exceeds a threshold value, for example, exceeds a threshold value that the network determines that the air interface is congested, send the target service carried by the unicast transmission channels to the terminal device through the multicast service channel. And otherwise, the target service is sent to the terminal equipment through a unicast service channel on an air interface.
Therefore, in the service transmission method provided by the embodiment of the invention, the target service borne by the unicast service channels is sent to the terminal equipment through the multicast service channel under the condition that the target service meets the preset condition, so that the resource waste caused by the transmission of the same service through the unicast service channels can be avoided.

S406: and deleting the unicast transmission channel established on the air interface.
In general, after the base station receives the target service sent by the core network device through the unicast service channel, the target service is also sent to the UE through the unicast service channel, where a unicast transmission channel may be already established before the target service sent by the core network device through the unicast service channel is received, so if a unicast transmission channel (e.g., DRB) is already established on the air interface for sending the core network unicast channel service, and if the target service carried by a plurality of unicast service channels is sent to the terminal device through the multicast service channel, the unicast transmission channel may be deleted. Thereby further avoiding waste of transmission resources.

S504: and receiving service information of the target service and/or identification of a unicast transmission channel sent by the core network equipment.
Steps S502 to S504 may be the same as steps S302 to S304 in the embodiment of fig. 3, and will not be described here again.

The UE can receive the target service through the multicast service channel by the configuration information of the target service, so that the UE can normally receive the target service sent by the unicast service channel of the core network and save transmission resources.
The embodiment of the application does not limit the sequence of steps S506 and S508, and can also be synchronously executed.
After this step, a step of deleting the unicast transmission channel established on the air interface may be further included, and in particular, see step S406 in the embodiment of fig. 4.
