The present invention relates to a mobile edge computing (MEC) technology, in particular to a system and method for traffic processing and diversion based on mobile edge computing user information.

Mobile Edge Computing (MEC) is an innovative network architecture that provides cloud computing functions and an information technology (IT) service environment for application service developers and content providers at the edge of the mobile network. Mobile Edge Computing (MEC) is characterized by ultra-low latency and high bandwidth. Because it is closer to the client, it can reduce network congestion and improve application performance. In response to the service-oriented trend of future mobile networks, such as V2X (Vehicle-to-Everything), self-driving cars, remote and drone control, multi-view live streaming of sports events, augmented reality and virtual reality, etc. Application, a large number of user traffic flooding into the mobile edge computing system at the same time requires a more effective dynamic traffic distribution mechanism to effectively reduce network delay and improve user experience.

When it floods into the system, the traffic dynamic offloading mechanism can be activated in real time to more effectively reduce network delay and improve user experience. It can also allocate and utilize the performance and capacity of mobile edge computing devices more effectively.

FIG. 1 is a schematic diagram of the architecture of the system 1 for traffic processing and distribution based on mobile edge computing user information in the present invention. Figure 2A is the user GTP (GPRS Tunnelling Protocol; GPRS Tunneling Protocol) data tunnel header information table T1 of the present invention, where GPRS is General Packet Radio Service.

Figure 2C is the VLAN-processing module resource corresponding information table T3 of the present invention. Figure 2D is the user data packet proxy module list T4 of the present invention. Figure 2E is a list T5 of user data packet processing modules of the present invention.

As shown in Figure 1, the system 1 for traffic processing and distribution based on mobile edge computing user information can include a signaling capture and analysis module 10, at least one user data packet proxy module 20, and at least one user data packet processing module. The structure of the module 30, an automatic resource increase/decrease module 40, a switch 50 and a dynamic distribution mechanism of user traffic.

The architecture of the above four modules (10, 20, 30, 40), switch 50 and user traffic dynamic offloading mechanism can be deployed on the same hardware platform, and the four modules, switch 50 and user traffic dynamics The structure of the shunt mechanism can communicate through a programmatic interface. Alternatively, the aforementioned four modules, the switch 50, and the architecture of the user traffic dynamic offload mechanism can be deployed on different hardware platforms, and the architecture of the four modules, the switch 50, and the user traffic dynamic offload mechanism can pass through General IP-based communication protocol for communication. At the same time, the present invention can be applied to 3G UMTS (Universal Moblle Telecommunications System), 4G LTE (Long Term Evolution) mobile network, 5G mobile network, higher-end or other mobile networks.

The signaling capture and analysis module 10 can provide the user GTP header packet information to the user data packet proxy module 20 through the user GTP data tunnel header information communication interface F, so that the user data packet proxy module 20 can according to the user GTP header packet The information generates the user GTP data tunnel header information table T1 as shown in Figure 2A, so that the user GTP data tunnel header information table T1 is used as the basis for subsequent traffic offloading.

The user data packet proxy module 20 can receive the information of the user GTP header packet from the signaling capture and analysis module 10, according to the user GTP header packet The packet information generates TEID (Tunnel Endpoint Identifier)-VLAN (Virtual Local Area Network) corresponding information table T2 as shown in Figure 2B, and VLAN-processing module resource corresponding information table T3 as shown in Figure 2C .

The user data packet processing module 30 can determine whether the user GTP header packet is a packet of the mobile edge computing service list (not shown in the figure) to perform the disassembly and encapsulation of the user GTP header packet.

The resource automatic increase/decrease module 40 can automatically add or delete the user data packet proxy module 20 according to the load of each user data packet proxy module 20 or user data packet processing module 30 (such as its processor or memory) Or the user data packet processing module 30, so that equipment resources can be effectively used.

The dynamic offloading mechanism of user traffic can be based on the received signaling capture and analysis module 10, user data packet proxy module 20, user data packet processing module 30, base station (such as eNodeB) or service gateway (not shown in the figure) ) The transmitted user traffic packet performs corresponding traffic diversion action.

In detail, the signaling capture and analysis module 10 can capture or receive signaling between the mobile wireless network 62 and the mobile core network 64, decode and analyze the signaling, and provide the user GTP (ie GPRS Tunneling Protocol). The information of the header packet is provided to the user data packet proxy module 20, so that the user data packet proxy module 20 generates a user GTP data tunnel header information table T1 as shown in Figure 2A based on the user GTP header packet information, so as to The user GTP data tunnel header information table T1 serves as the basis for subsequent traffic diversion. The aforementioned mobile core network 64 can be connected to the Internet 65.

User data packet proxy module 20 can receive signal capture and analysis Information about the user GTP header packet of module 10, query the current resource load status of each user data packet processing module 30 in the current VLAN-processing module resource corresponding information table T3, and select the current lightest load (such as processor/memory/ The user data packet processing module 30 of the I/O port (Disk IO)/number of users is the lightest) and obtains the VLAN ID (Virtual Local Area Network Identifier), and obtains the TEID (Tunnel Endpoint Identifier) from the user GTP header packet ) Information, and add TEID-VLAN corresponding information in the TEID-VLAN corresponding information table T2. At this time, if there are multiple user data packet proxy modules 20 (such as 21 to 2n), synchronize user GTP data tunnel header information table T1, TEID-VLAN corresponding information table T2, VLAN-processing module resource corresponding information table T3 to each user data packet proxy module 20, and synchronously transmits the user GTP data tunnel header information table T1 to each user data packet processing module 30.

The user data packet processing module 30 has the function of disassembling and encapsulating the user GTP header packet to determine whether the destination IP in the user GTP header packet is a packet of the mobile edge computing service list. If it is (the destination IP in the user GTP header packet is a packet of the mobile edge computing service list), the user data packet processing module 30 disassembles and encapsulates the user GTP header packet and sends it to the mobile wireless network 62 or mobile edge computing (MEC) server 63; if not (the destination IP in the user GTP header packet is not a packet in the mobile edge computing service list), the user data packet processing module 30 directly transmits the user GTP header packet to the mobile core network 64.

The resource automatic increase/decrease module 40 can automatically add a new user data packet proxy module when the load of each user data packet proxy module 20 or user data packet processing module 30 (such as its processor or memory) exceeds X% 20 or User data packet processing module 30. When the load of each user data packet proxy module 20 or user data packet processing module 30 is lower than Y% (such as X>Y), or the average load of all user data packet proxy modules 20 and user data packet processing modules 30 When it is lower than Z% (such as X>Z>Y), the resource automatic increase/decrease module 40 selects the user data packet proxy module or user data packet processing module 30 with the lightest load and automatically deletes them, where X, Y, and Z are all The value is greater than 0 and less than 100, and X is greater than Z greater than Y.

However, before the automatic resource increase/decrease module 40 selects the user data packet processing module with the lightest load for deletion, the automatic resource increase/decrease module 40 must first notify the default user data packet agent module 21 to stop distributing user data to The user data packet processing module with the lightest load, and the user data of the user data packet processing module with the lightest load is synchronized to other user data packet processing modules with low load, then the user data packet processing with the lightest load can be deleted The module then deletes the information of the user data packet processing module with the lightest load from the user data packet processing module list T5 and the TEID-VLAN corresponding information table T2, and simultaneously updates the information of the TEID-VLAN corresponding information table T2.

The dynamic distribution mechanism of user traffic includes two parts: the dynamic distribution mechanism of the user data packet proxy module 20 and the dynamic distribution mechanism of the switch 50. The dynamic offload mechanism of the user data packet proxy module 20 can obtain TEID (Tunnel Endpoint Identifier) information for the packet from the signaling capture and analysis module 10, and obtain the corresponding VLAN ID according to the TEID-VLAN correspondence information table T2 ( (Virtual Local Area Network ID) information, after adding VLAN ID information to the user traffic packet, the user traffic packet is sent to the switch 50. Switch 50 can perform traffic offloading according to the VLAN ID information added to the user traffic packet by the user data packet proxy module 20, so as to transmit the user traffic packet to the corresponding user data packet processing module 30.

For example, the dynamic distribution mechanism of the switch 50 includes the following three: (1) When the switch 50 receives a user traffic packet transmitted by the base station or the Serving Gateway, the switch 50 is made to share the load ( The user traffic packet is transmitted to the user data packet proxy module 20 in a load sharing) mode. (2) When the switch 50 receives the user traffic packet sent by the user data packet proxy module 20, the switch 50 is made to send the user traffic packet to the corresponding user data packet for processing according to the VLAN ID information of the user traffic packet Module 30. (3) When the switch 50 receives the user traffic packet transmitted by the user data packet processing module 30, the switch 50 is made to transmit the user traffic packet to the mobile wireless network 62 according to the destination address of the user traffic packet , Mobile edge computing server 63 or mobile core network 64. Therefore, the dynamic offloading mechanism of the switch 50 can perform corresponding traffic offloading actions based on user traffic packets transmitted in different directions.
