Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic flow chart of a 5G flow diversion method according to a first embodiment of the present application. The 5G flow diversion method can be applied to a server and used for determining the final flow direction through the target IP information, and when the target data packet is determined to be sent to the data processing equipment, the target data packet is processed according to the IP-GTP information list and sent to the data processing equipment, so that the controllability of 5G communication resources is improved, and the technical problem of low controllability of the 5G communication resources is solved.

In a specific embodiment, as shown in fig. 2, fig. 2 is a schematic working diagram of a 5G traffic splitting device, where the device is connected in series between a 5G base station and an operator's equipment, and service data of all industrial park 5G terminals are forwarded to a target address by the device. The traffic direction according to the traffic data can be divided into uplink traffic and downlink traffic data. The uplink flow is the service data sent to the destination address by the 5G terminal through the 5G base station and the device of the invention; the downlink flow is the business data which is sent to the 5G terminal of the industrial park after the business server responds to the terminal request and is sent from the server through the device and the base station. The upstream traffic data may be classified into intra-campus traffic data and off-campus traffic data according to the destination address. Before the device of the invention, the on-campus and off-campus traffic data will be sent to a 5G core network deployed at the operator, where the on-campus traffic data is routed back to the on-campus industrial data processing facility.
Traffic data on the campus also needs to be routed to the operator's room to be routed to data processing equipment local to the campus, which tends to increase the delay of the data and also leaves the possibility of exposing the traffic data. The device can directly shunt the service data in the 5G terminal uplink park of the industrial park to the industrial data processing equipment according to the preconfigured rule without forwarding through an operator 5G core network.
The 5G flow splitting device is composed of a plurality of functional modules and comprises: the system comprises a system main controller, a configuration module, a high-speed data message processing module, a rule matching module, a statistics module and a log module.
The main controller is responsible for coordinating the calling and supervision of each functional module, so that the whole device operates orderly;
the configuration module is configured to configure local traffic data offload rules, which may be one or a combination of some of the following rules, including: an uplink data message destination IP address; a target IP port of the uplink data message; a target IP protocol of the uplink data message; the target domain name of the uplink data message. The number of the rules is not less than 1000, and the configuration can be completed, modified, deleted and other daily management through CLI commands or management interfaces.
The rule matching module is used for storing the rule of the configuration module and expanding the rule according to a certain algorithm so as to quickly match whether the uplink service data message can trigger the local shunting rule or not, and the module is mainly called by the data message processing module.
The data message processing module is used for processing (receiving and transmitting) uplink and downlink service data, and when the uplink data message is received from the network, the module determines whether to perform local shunting processing on the data message by calling a rule matching module. If the local shunting condition is not met, the data is directly forwarded according to the original path. If the local shunting condition is met, the local shunting of the data is finished by forwarding the local shunting condition to the local data processing equipment through the routing equipment. The downlink data sent from the local data processing equipment are all forwarded to the 5G base station, and the routing of the data from the equipment to the industrial 5G terminal is completed.
The statistics module is used for counting the data traffic of the uplink and downlink local shunting, and can count the traffic according to time periods or days or weeks. The statistical result is stored in the equipment according to a certain naming rule in real time.
The log module is mainly used for outputting and storing system operation log and state information, and the information can be output to a designated position according to configuration so as to enable management personnel to monitor the system operation state in real time.
The embodiment discloses a 5G traffic distribution method, a device and a storage medium, wherein the 5G traffic distribution method comprises the steps of receiving a target data packet sent by a 5G terminal, wherein the target data packet comprises target IP information and target GTP information; determining a final flow direction of the target data packet based on the target IP information; if the final flow direction is the 5G core network, the target data packet is sent to the 5G core network; and if the final flow direction is the data processing equipment, transmitting the target data packet to the data processing equipment based on the information in a preset IP-GTP information list, wherein the preset IP information list and the preset GTP information list in the IP-GTP information list are in one-to-one correspondence. The one-to-one correspondence between the IP information list and the GTP information list is matched by the device through online learning, so that the device is used as a preset condition when processing specific data packets. According to the method and the device, the final flow direction is determined through the target IP information, and when the target data packet is determined to be sent to the data processing equipment, the target data packet is processed according to the IP-GTP information list and is sent to the data processing equipment, so that the controllability of 5G communication resources is improved, and the technical problem of low controllability of the 5G communication resources is solved.
Referring to fig. 3, fig. 3 is a schematic flow chart of a 5G flow diversion method according to a first embodiment of the present application. The 5G flow diversion method can be applied to a server and used for determining the final flow direction through the target IP information, and when the target data packet is determined to be sent to the data processing equipment, the target data packet is processed according to the IP-GTP information list and sent to the data processing equipment, so that the controllability of 5G communication resources is improved, and the technical problem of low controllability of the 5G communication resources is solved.
Based on the embodiment shown in fig. 1, in this embodiment, as shown in fig. 2, the step S40 specifically includes steps S41 to S44.

step S42, if the preset IP information which is the same as the target IP information does not exist in the preset IP information list, storing the target IP information and the GTP information into the preset IP-GTP information list, and then sending the target data packet to the data processing equipment;
step S43, if the preset IP information list has preset IP information identical to the target IP information and GTP information corresponding to the preset IP information is different, deleting the GTP information corresponding to the preset IP information, storing the target GTP information corresponding to the target IP information into the preset IP-GTP information list, and then transmitting the target data packet to the data processing equipment;
step S44, if the preset IP information which is the same as the target IP information exists in the preset IP information list and GTP information corresponding to the preset IP information is the same as the target GTP, the target data packet is sent to the data processing equipment.
In a specific embodiment, if the network access operation of the terminal occurs in a certain service flow, that is, the last service flow has not completed the state of the terminal, so that the last service data is in a waiting state because the binding relationship between the terminal UE IP and the TEID may be refreshed when the service data passes through the device, and there is no failure in forwarding the downlink service data generated by the campus industrial data processing device, where the campus industrial data processing device cannot acquire the entire link routing condition.
If there are a lot of network terminals in the above situation, for example, a local power trip accident causes all the 5G terminals in the area to reselect to the network, so that many data links are in waiting state for the industrial data processing equipment in the campus.
An abnormally high number of data links in a waiting state may result in insufficient available resources of the campus industrial data processing device or a failure to process the service data of the normal terminal in time, resulting in confusion of the entire campus device.
The device makes pairing binding for the TEID information of the GTP header of the user and the UE IP address information, so that the UE IP address can be searched through the GTP header TEID information, and the GTP header TEID information can also be obtained through the UE IP address searching. Specifically, uplink GTP TEID information of a certain user is allocated by the core network, and header TEID information of downlink GTP is allocated by the base station.
And obtaining two results by querying a rule base.
The first result is that the upstream packet does not meet the local offload requirement.
The second type of resulting upstream packet meets the local offload requirement.
For the uplink data packet which does not meet the local shunting requirement in the first case, the device does not process, and continues to send the original data packet to the operator 5G core network according to the original routing mode.
For the uplink data packet meeting the local shunting requirement in the second case, the device removes the GTP data encapsulation packet header to restore the data into the original IP data packet, so that the data packet can directly finish routing in the IP equipment.
The device increases statistics of the split data packets, including the number of the data packets, the number of bytes and the like.
The device sends the IP data packet processed by the steps according to the target IP address.
And the local park uplink data packet reaches the park industrial data processing equipment through the routing equipment to complete the local shunting flow.
Based on the embodiment shown in fig. 3, in this embodiment, the step S43 further includes:
and sending a resource release instruction to the data processing equipment so as to inform the data processing equipment to release the processing resources of the preset IP information and the corresponding preset GTP.
Based on the embodiment shown in fig. 1, in this embodiment, the step S40 includes:
and deleting target GTP information in the target data packet when the final flow direction is determined to be the data processing equipment, and sending the processed target data packet to the data processing equipment.
Based on the embodiment shown in fig. 1, in this embodiment, the step S40 includes:
when receiving a return data packet fed back by the data processing device, adding return GTP information corresponding to the return IP information into the return data packet based on the return IP information contained in the return data packet and the preset IP-GTP information list.
In a specific embodiment, the device encapsulates the original IP packet from the second source in a GTP packet format, that is, obtains the context of the terminal by searching the IP address of the corresponding terminal, including the downlink TEID, and fills the GTP packet header.
The device sends the encapsulated data packet from the second source to the 5G base station, and the 5G base station sends the data packet to the 5G terminal of the corresponding park through wireless.
Referring to fig. 4, fig. 4 is a schematic flow chart of a 5G flow diversion method according to a third embodiment of the present application. The 5G flow splitting method can be applied to a server, and is used for searching GTP information to be determined, which is matched with target GTP information, in a preset IP-GTP information list after the target GTP information is determined through a target IP address, and sending a data packet to a 5G core network under the condition that the target GTP information is the same as the GTP information to be determined, so that the controllability of 5G communication resources is improved, and the technical problem of low controllability of the 5G communication resources is solved.
In this embodiment, the 5G flow diversion further includes steps S50 to S70.
Step S50, if a new connection instruction sent by the 5G terminal is received, acquiring the target data packet corresponding to the reconnected 5G terminal, and updating the mapping relation between the target IP address and the target GTP information in the preset IP-GTP information list based on the target data packet corresponding to the reconnected 5G terminal;
step S60, if a restarting instruction sent by the 5G base station is received, notifying the data processing equipment to release all resources, and updating the mapping relation between all preset IP addresses and preset GTP information through the preset IP-GTP information list;
and step S70, deleting the mapping relation corresponding to the 5G terminal if the target data packet sent by the 5G terminal is not received in a preset time period, and releasing the resources corresponding to the 5G terminal through the data processing equipment so as to realize 5G network shunting.

(the difference between the first is that the active new connection instruction of the 5G terminal (the terminal needs to reacquire the IP address in general) and the second is that the restart of the 5G base station, the IP address of the 5G terminal is not necessarily changed, but the GTP header information corresponding to the IP address is changed
If a certain IP address in the list does not receive the information of the 5G terminal for a long time, deleting the IP address mapping and notifying the industrial data processing equipment to release the corresponding resource.

When the uplink data packet flows through the device, the device opens the GTP header of the uplink data packet (namely, passes through the length of the GTP header), so that the information of the destination IP address, the port, the protocol and the like of the data packet is obtained.
The device encapsulates the original IP data packet from the second source in GTP data packet format, namely, obtains the context of the terminal by searching the IP address of the corresponding terminal, including downlink TEID, and fills the GTP packet header.

The configuration module monitors and inputs the local shunting rule configuration (adding, modifying and deleting operations) in real time and stores the result in real time, and the operation can be completed through network management or CLI. The splitting rule is exemplified as follows:
rule #1: dstlip= 192.168.1.128and dstPort =3000
