As described in the background art, the existing service transmission method requires a large number of gateway devices, resulting in high complexity of network construction.

Because the target service is a fixed network service sent through a fixed network or a mobile network service sent through a mobile network, the method and the device can realize the transmission of service messages of different network types on one device. Therefore, gateway equipment does not need to be deployed for services of different network types, the number of the gateway equipment is effectively reduced, and the complexity of network construction is further reduced.
The service transmission method is suitable for a service transmission system. Fig. 1 shows a structure of the service transmission system. As shown in fig. 1, the service transmission system includes: gateway device 101, transmitting end 102, and receiving end 103.

In the embodiment of the present application, the software programs stored in the memory 22 are different for the gateway apparatus 101, the transmitting end 102, and the receiving end 103, so the functions realized by the gateway apparatus 101, the transmitting end 102, and the receiving end 103 are different.

It should be noted that the structure shown in fig. 5 (or fig. 6) does not constitute a limitation of the communication apparatus, and the communication apparatus may include more or less components than those shown in fig. 5 (or fig. 6), or may combine some components, or may be arranged in different components.
The service transmission method provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings.
As shown in fig. 7, the service transmission method provided in the embodiment of the present application is applied to a gateway device, and includes: S701-S703.
S701, the gateway device receives a first service message for requesting a transmission target service.
The target service is a fixed network service sent through a fixed network or a mobile network service sent through a mobile network.
Specifically, in the service transmission process, the gateway device may receive, through the ASIC, a fixed network service sent by the sending end through the fixed network or a mobile network service sent by the mobile network, so that the gateway device may perform message forwarding processing on the fixed network service or the mobile network service.
Wherein the first service message includes a service identification of the target service.
Alternatively, the fixed network service may be a home broadband service, a network protocol television (internet protocol television, IPTV) service, or an enterprise private line service.
Alternatively, the mobile network service may be a third generation mobile communication technology (3 th-generation, 3G), a fourth generation mobile communication technology (4 th-generation, 4G), or a 5G mobile broadband service.
Alternatively, the service identifier may be a service number, a service name, or the like.
S702, the gateway equipment reads the pre-stored service routing information and determines a routing strategy corresponding to the service identifier.
The service routing information comprises routing information for transmitting fixed network service and routing information for transmitting mobile network service.
Specifically, after receiving the first service message, in order to enable the second service message of the service message to be transmitted to the receiving end according to the routing policy, the gateway device may determine, from the service routing information stored in advance in the database, a corresponding routing policy according to the service identifier of the target service.
Alternatively, the routing policy may refer to a target network segment, a mask, a next hop device, a metric value, and so on.
Alternatively, the pre-stored traffic routing information may be acquired in advance by the gateway device.
Specifically, in connection with fig. 3, the method for obtaining service routing information by the gateway device may include: the configuration issuing module receives network service configuration parameters issued by the network element management system and the network controller. Then, the configuration analysis module analyzes the network service configuration parameters and converts the network service configuration parameters into service routing information of the machine-readable codes. Subsequently, the traffic routing information is stored in a database.
S703, the gateway equipment sends a second service message for transmitting the target service according to the routing strategy.
Specifically, in the service transmission process, the gateway device may send the second service message to the receiving end according to the routing policy.
Optionally, after receiving the first service message, the gateway device may perform processing of encapsulating and decapsulating the data message on the first service message, so as to obtain the second service message.
The preset gateway device receives a first service message (including a service identifier a) sent by the terminal and used for transmitting the service a. The gateway device reads the service routing information stored in the database in advance, and determines the routing strategy (including the destination address as the core network device) corresponding to the service identifier a. Then, the gateway device may perform a processing of decapsulating the data packet on the first service message, to generate a second service message with a destination address for transmitting the service a as the core network device. And then, the gateway equipment sends a second service message to the core network equipment according to the routing strategy.
In one embodiment, in conjunction with fig. 7, as shown in fig. 8, prior to S703, the method further comprises: s801.
S801, the gateway equipment calls a target driver to perform the encapsulation and decapsulation processing of the data message on the first service message so as to obtain a second service message.
When the target service is the fixed network service, the target drive is a first drive for carrying out the encapsulation and decapsulation processing of the data message on the fixed network service, and when the target service is the mobile network service, the target drive is a second drive for carrying out the encapsulation and decapsulation processing of the data message on the mobile network service.
Specifically, since the first service message is a service message communicated between the sending end and the gateway device, and the second service message is a service message communicated between the gateway device and the receiving end, a data message for transmitting the first service message is different from a data message for transmitting the second service message. Therefore, the gateway device may invoke the target driver corresponding to the network type according to the network type corresponding to the target service to perform the encapsulation and decapsulation processing of the data message on the first service message, so that the gateway device may update the first service message into the second service message.
Alternatively, in connection with fig. 3, the first driver may be an ASIC-driver in the kernel layer of the gateway device, and the second driver may be an ASIC-UPF-driver in the kernel layer of the gateway device.
Optionally, the method for determining the network type of the target service by the gateway device includes: the gateway device determines a network type of a port receiving the first traffic message as a network type of the target traffic. Or the gateway equipment determines the network type corresponding to the address field as the network type of the target service according to the address field carried in the received message of the first service message.
Illustratively, the header received by the preset gateway device for transmitting the first service message of the service a includes a point-to-point protocol over ethernet (PPPoE) address field on the ethernet. Since the PPPoE address field corresponds to a fixed network, the gateway device determines that service a is a fixed network service. After the gateway equipment determines that the routing strategy of the service A comprises a receiving end, the ASIC-driver is called to carry out the encapsulation and decapsulation processing of the data message on the first service message, so as to obtain a second service message. And then, the gateway equipment sends a second service message to the receiving end through the ASIC-driver.
In one embodiment, as shown in fig. 8, before S801, the method further includes: s802.
S802, the gateway equipment calls target computing resources for the target driver, so that the target driver performs the processing of adding and de-packaging the data message on the first service message.
Specifically, before the target driver is invoked to perform the processing of adding and decapsulating the data message on the first service message, the gateway device may determine, according to the service identifier of the target service, a hardware module or a software module corresponding to the service identifier. And then, the gateway equipment calls a corresponding hardware module or software module to provide target computing resources for the target driver so that the target driver can carry out the encapsulation and decapsulation processing of the data message on the first service message.
In connection with fig. 3, the resource scheduling module of the gateway device may determine, according to the service identifier of the target service, a hardware module or a software module corresponding to the service identifier. Then, the resource scheduling module transmits a request message requesting for the call to the corresponding hardware module or software module. The corresponding hardware module or software module provides the target computing resource for the target drive in response to the request message.
Optionally, the computing resources are CPU resources, memory resources, hard disk resources, network resources, and the like required by the gateway device during operation. In one embodiment, in conjunction with fig. 8, as shown in fig. 9, prior to S703, the method further comprises: s901.
And S901, when the target service is a service type which cannot be processed by the target driver, the gateway equipment calls another driver except the target driver to perform the encapsulation and de-encapsulation processing of the data message on the first service message so as to obtain a second service message.
Specifically, when the first service message is received, the gateway device may determine, according to the service identifier, whether the target service is a service type that cannot be processed by the target driver. When the target service is a service type which cannot be processed by the target driver, the gateway device can call another driver except the target driver to perform the encapsulation and decapsulation processing of the data message on the first service message so as to obtain a second service message, so that the gateway device can flexibly process multiple types of services.
Alternatively, in connection with fig. 3, another driver may be an FPGA-driver in the kernel layer of the gateway device.
The first service message (including the service identifier a) received by the gateway device and used for transmitting the service a is preset. When the service type that the target service cannot be processed by the target driver is determined according to the service identifier a, after the gateway equipment determines that the routing strategy of the service A comprises the receiving end, the FPGA-driver can be called to perform the encapsulation processing of the data message on the first service message, so as to obtain the second service message. And then, the gateway equipment sends a second service message to the receiving end through the FPGA-driver.
In one embodiment, referring to fig. 7, as shown in fig. 10, the method for determining a routing policy corresponding to a service identifier by reading, by a gateway device, pre-stored service routing information in S702 specifically includes: s1001.
S1001, the gateway equipment calls a target container running through the container mirror image, and determines a routing strategy corresponding to the service identifier from service routing information.
When the target service is a fixed network service, the target container is a first container for determining a routing policy corresponding to the fixed network service, and when the target service is a moving network service, the target container is a second container for determining a routing policy corresponding to the moving network service.
Specifically, when the gateway device receives the first service message, the network type corresponding to the target service may be determined. Then, the target driver of the gateway device sends the service type of the target service to the corresponding target container according to the network type. Then, the target container determines a routing strategy corresponding to the service identifier according to the service routing information of the database and sends the routing strategy to the target driver, so that the gateway equipment sends a second service message for transmitting the service message to the receiving end according to the routing strategy.
Alternatively, in connection with fig. 3, the first container may be a BRAS container in the user layer of the gateway device, and the second container may be a UPF container in the user layer of the gateway device.
The service identifier of the first service message is preset as a first packet message with 5-tuple flow as granularity. After the gateway device determines that the target service is a network-moving service, a message is sent to a UPF container through an ASIC-UPF-driver, and the UPF container generates a routing policy (including forwarding or discarding) with 5-tuple flow granularity. And the ASIC-UPF-driver forwards the message.
Alternatively, when the routing policy of the target service is acquired, the target driver may send a second service message for transmitting the target service according to the routing policy.
The first service message is illustratively a mobile network data flow follow-up message with 5-tuple flow as granularity. After the gateway equipment determines that the target service is the network-moving service, the data message forwarding processing (namely, the two-layer and three-layer message header decapsulation) is performed through the ASIC-UPF-driver, and the routing strategy is obtained to directly process and forward.
In summary, in the service transmission process of the service transmission device in the embodiment of the present application, after receiving a first service message for requesting to transmit a target service and including a service identifier of the target service, the service transmission device may determine a routing policy corresponding to the service identifier by reading pre-stored service routing information, and then send a second service message for transmitting the target service according to the routing policy. Because the target service is a fixed network service sent through a fixed network or a mobile network service sent through a mobile network, the method and the device can realize the transmission of service messages of different network types on one device. Therefore, gateway equipment does not need to be deployed for services of different network types, the number of the gateway equipment is effectively reduced, and the complexity of network construction is further reduced.
Specifically, after obtaining the updated service identifier, the server may send the updated service identifier to the second node device connected to the terminal, because the updated service identifier includes the unique identifier of the terminal.
