[0035] Figure 3 This is the second flowchart of the communication method provided by the present invention.
[0036] Figure 4 This is a schematic diagram of the structure of the instrument provided by the present invention. Detailed Implementation
[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0038] Figure 1 This is one of the flowcharts illustrating the communication method provided by the present invention, such as... Figure 1 As shown, this invention provides a communication method, the execution subject of which can be an instrument, which can be a device for terminal testing, such as a device for testing the terminal's services, testing whether the protocol used by the terminal conforms to standards, etc. The method includes: Step 101: Receive downlink data sent by the target server; the downlink data includes the target server's Internet Protocol IP address and the target terminal's IP address.
[0039] Specifically, the target server sends downlink data to the instrument, which includes the target server's Internet Protocol (IP) address and the target terminal's IP address; the instrument receives the downlink data sent by the target server.
[0040] The target server can be an external server (i.e., an external network server) or an Image Management Service (IMS) server. The IMS server deploys network performance testing tools (iperf repackaging tools) and file transfer tools (ftp transfer tools) to support iperf repackaging and file transfer functions.
[0041] For example, Figure 2 This is a schematic diagram of the networking mode of the communication method provided by the present invention, as shown below. Figure 2 As shown, after the terminal is connected to the instrument, it can communicate with the external server through the instrument. The terminal is connected to the instrument via an RF cable, and the external server is connected to the instrument via a network cable.
[0042] For example, such as Figure 2 As shown, after the terminal is connected to the meter, it can communicate with the IMS server through the meter. The terminal is connected to the meter via an RF cable. A switch is needed to forward data between the meter and the IMS server. The meter and the switch, as well as the switch and the IMS server, are all connected via network cables.
[0043] In this embodiment of the application, when the terminal's service type is a low-speed service (such as voice service), the terminal communicates with the MS server through the instrument; when the terminal's service type is a high-speed service (such as video call service), the terminal communicates with an external server through the instrument.
[0044] Step 102: Determine the Target Tunnel Endpoint Identifier (TEID) based on the configuration information, the target server IP address, and the target terminal IP address. The configuration information includes one or more sets of associated information, each set of associated information including the terminal IP address, the server IP address, and the TEID.
[0045] Specifically, the instrument receives downlink data sent by the target server, obtains the target server IP address and the target terminal IP address from the downlink data, and determines the target tunnel endpoint identifier (TEID) based on the configuration information and the obtained target server IP address and target terminal IP address.
[0046] The configuration information includes one or more sets of association information, each set of association information being a set of associated terminal IP addresses, server IP addresses, and TEID, etc.
[0047] For example, the instrument receives downlink data sent by the target server, learns from the downlink data that the target server IP address is server IP-1 and the target terminal IP address is terminal IP-1, then matches the association information between server IP-1 and terminal IP-1 in the configuration information, and determines the target TEID based on the matched association information.
[0048] Step 103: Send downlink data to the target terminal via the target TEID.
[0049] Specifically, obtaining the target TEID identifies the endpoint of the data transmission tunnel between the instrument and the target terminal, enabling the instrument to send downlink data to the target terminal via the target TEID. The target terminal then receives the downlink data sent by the instrument.
[0050] The communication method provided in this application embodiment is based on an instrument receiving downlink data sent by a target server. This downlink data includes the target server IP address and the target terminal IP address. Then, the instrument determines a target TEID based on configuration information, the target server IP address, and the target terminal IP address. The configuration information includes one or more sets of association information, each set including the terminal IP address, server IP address, and TEID. Finally, the downlink data is sent to the target terminal using the target TEID. This method enables the server to communicate directly with the terminal via the instrument, eliminating the need for core network forwarding, reducing costs, minimizing data interaction, and lowering communication latency between the terminal and the server.
[0051] In some embodiments, the baseband board in the instrument includes multiple Layer 2 components, and each set of associated information further includes Layer 2 identification information; determining the Target Tunnel Endpoint Identifier (TEID) based on configuration information, the target server IP address, and the target terminal IP address includes: The main control board in the instrument obtains the identification information of the target layer 2 from the configuration information based on the target server IP address and the target terminal IP address, and determines the Media Access Control (MAC) address of the target layer 2 according to the identification information of the target layer 2. The main control board sends downlink data to the target layer 2 based on the MAC address of the target layer 2; The target layer 2 receives downlink data sent by the main control board and obtains the target TEID corresponding to the identification information of the target layer 2 from the configuration information.
[0052] Specifically, the instrument includes a baseband board and a main control board. Figure 3 This is a second flowchart illustrating the communication method provided by the present invention, as shown below. Figure 3 As shown, the terminal (UE) is directly connected to the instrument's baseband board, the baseband board inside the instrument is directly connected to the main control board, and the main control board of the instrument is directly connected to the server. The baseband board is used to receive uplink data sent by the terminal and send the uplink data to the main control board, and also to receive downlink data sent by the main control board and send the downlink data to the terminal; the main control board is used to receive uplink data sent by the baseband board and send the uplink data to the server, and also to receive downlink data sent by the server and send the downlink data to the baseband board.
[0053] The baseband board includes multiple Layer 2 data link layers. Each Layer 2 is identified by identification information, which can be the core number of the Layer 2. Each Layer 2 corresponds to a unique core number, which is used to distinguish different Layer 2s. Each Layer 2 or each core number also corresponds to a MAC address.
[0054] Each set of associated information also includes Layer 2 identification information, which includes a set of interconnected terminal IP addresses, server IP addresses, TEIDs, and Layer 2 identification information.
[0055] To determine the target TEID, firstly, the main control board in the instrument matches the Layer 2 identifier information associated with both the target server IP address and the target terminal IP address in the configuration information, thus obtaining the target Layer 2 identifier information. Based on this identifier information, the MAC address of the target Layer 2 is determined. This target Layer 2 is used to send downlink data to the target terminal. Then, the main control board in the instrument sends the downlink data to the target Layer 2 based on its MAC address. Finally, the target Layer 2 receives the downlink data sent by the main control board and retrieves the target TEID corresponding to its identifier information from the configuration information.
[0056] For example, the main control board in the instrument receives downlink data sent by the target server. From the downlink data, it learns that the target server's IP address is Server IP-1 and the target terminal's IP address is Terminal IP-1. The main control board matches the Layer 2 identifier information associated with both Server IP-1 and Terminal IP-1 in the configuration information. The matched identifier information is Layer 2-2, meaning the target Layer 2 is Layer 2-2. The main control board then sends the downlink data to Layer 2-2 in the baseband board. After receiving the downlink data, Layer 2-2 matches the TEID associated with both Terminal IP-1 and Layer 2-2 in the configuration information, thus obtaining the target TEID.
[0057] The communication method provided in this application embodiment uses the main control board in the instrument to match the identification information of the target layer 2 based on the configuration information, so that the downlink data is sent to the target layer 2 for processing. The target layer 2 matches the target TEID based on the configuration information and sends the downlink data to the target terminal through the target TEID. This enables the instrument to determine the target TEID on its own, so that the server can communicate directly with the terminal through the instrument without going through the core network, reducing data interaction and reducing the communication latency between the terminal and the server.
[0058] In some embodiments, sending downlink data to the target layer 2 based on the MAC address of the target layer 2 includes: The main control board encapsulates the downlink data into a first MAC field; the source MAC address in the first MAC field is the MAC address of the main control board, and the destination MAC address in the first MAC field is the MAC address of the target layer 2. The main control board sends the first MAC field to the target layer 2.
[0059] Specifically, after the main control board in the instrument obtains the MAC address of the target layer 2, it encapsulates the downlink data based on the MAC address of the target layer 2. This includes changing the source MAC address and destination MAC address in the data packet. The source MAC address is changed to the MAC address of the main control board, and the destination MAC address is changed to the MAC address of the target layer 2, thereby obtaining the encapsulated downlink data packet, i.e., the first MAC field, and then sending the first MAC field to the target layer 2.
[0060] The terminal communication method based on the instrument provided in this application embodiment involves the main control board in the instrument changing the source MAC address and the destination MAC address, and sending the first MAC field obtained by encapsulating the downlink data to the target layer 2, so that the target layer 2 receives the downlink data and sends it to the target terminal, thus ensuring the smooth transmission of downlink data.
[0061] In some embodiments, the baseband board in the instrument further includes a driver module; transmitting downlink data to the target terminal via the target TEID includes: The driver module encapsulates downlink data based on the target TEID; the target TEID is used to identify the data transmission tunnel between the target terminal and the target Layer 2. The target layer 2 sends the encapsulated downlink data to the target terminal.
[0062] Specifically, the baseband board in the instrument also includes a driver module, which is used to encapsulate the data received by the baseband board. In downlink transmission, the baseband board receives downlink data sent by the main control board, determines the target TEID, and then encapsulates the downlink data based on the target TEID, that is, encapsulates the target TEID into the data packet header. Then, the target layer 2 sends the encapsulated downlink data to the target terminal.
[0063] The communication method provided in this application encapsulates the acquired target TEID into a downlink data packet through a driver module, enabling downlink data to be successfully transmitted to the target terminal through the target TEID. This allows the terminal and server to communicate only through the instrument, reducing the communication latency between the terminal and the server.
[0064] In some embodiments, the method further includes: Before the target terminal is connected to the instrument, the configuration information sent by the main control tool MCT is received; the configuration information includes one or more sets of association information corresponding to different terminals, and the TEID in the configuration information is empty; After the target terminal is connected to the instrument, it receives the target TEID corresponding to the target terminal sent by MCT and updates the configuration information according to the target TEID.
[0065] Specifically, the configuration information is sent to the instrument by the Main Control Tool (MCT). Each set of associated information in the configuration information may include the terminal IP address, server IP address, TEID, layer 2 identification information, and protocol type. The protocol type refers to the protocol type used by the Flow data packet carrying the configuration information, including protocol types such as Transmission Control Protocol (TCP) and User Datagram Protocol (UDP).
[0066] MCT can send configuration information to the meter before the target terminal connects to the meter. The configuration information includes one or more sets of association information corresponding to different terminals, and the TEID in the configuration information is empty at this time. The meter receives the configuration information sent by MCT.
[0067] After the target terminal connects to the instrument, a higher layer, such as a Non-Access Stratum (NAS), provides the MCT with a TEID usable by the target terminal, i.e., the target TEID. The MCT then sends the target TEID to the instrument, notifying the instrument to update the TEID corresponding to the target terminal in the configuration information to the target TEID, thereby ensuring the completeness of the information associated with the target terminal in the configuration information. It should be noted that in this embodiment, all servers capable of communicating with the terminal are known; therefore, the target TEID determined by the higher layer for the target terminal is actually the target TEID determined for both the target terminal and a specific server.
[0068] For example, MCT provides configuration information for the instrument, including (Terminal IP-1, Server IP-1, 0, Layer 2-1, Protocol Type-1), (Terminal IP-1, Server IP-2, 0, Layer 2-2, Protocol Type-2), (Terminal IP-1, Server IP-1, 0, Layer 2-3, Protocol Type-1), (Terminal IP-2, Server IP-2, 0, Layer 2-4, Protocol Type-2), etc. In the configuration information, 0 (i.e., the position where TEID information is stored is filled with 0) indicates that the TEID information is empty. Terminal 1 (IP address: Terminal IP-1) connects to the meter. MCT sends the available TEID-1 (corresponding to Server 1) and TEID-2 (corresponding to Server 2) of Terminal 1 to the meter. The meter uses TEID-1 and TEID-2 to update the relevant associations in the configuration information, resulting in the following configuration information for Terminal 1: (Terminal IP-1, Server IP-1, TEID-1, Layer 2-1, Protocol Type-1) and (Terminal IP-1, Server IP-2, TEID-2, Layer 2-2, Protocol Type-2). After receiving the downlink data, the meter obtains the target TEID based on the updated configuration information.
[0069] The communication method provided in this application embodiment provides configuration information for the instrument in advance through MCT. After the terminal connects to the instrument, it only needs to send the TEID information corresponding to the terminal to the instrument, which reduces the amount of data sent and saves transmission resources.
[0070] In some embodiments, the method further includes: After the target terminal is connected to the meter, it receives configuration information sent by MCT; the configuration information includes one or more sets of association information corresponding to the target terminal.
[0071] Specifically, MCT can provide configuration information to the instrument after the target terminal is connected to the instrument. At this time, the configuration information only includes one or more sets of associated information corresponding to the target terminal.
[0072] For example, after terminal 1 (IP address: terminal IP-1) connects to the meter, MCT sends one or more sets of association information corresponding to terminal 1 to the meter, including (terminal IP-1, server IP-1, TEID-1, layer 2-1, protocol type-1) and (terminal IP-1, server IP-2, TEID-2, layer 2-2, protocol type-2). After receiving the downlink data, the meter obtains the target TEID based on this one or more sets of association information.
[0073] The communication method provided in this application allows for the configuration of the terminal's corresponding configuration information after the terminal is connected to the meter. This eliminates the need for the meter to update the configuration information; instead, it directly uses the configuration information sent by the MCT, making the operation simpler and reducing downlink transmission latency.
[0074] In some embodiments, the method further includes: Receive uplink data sent by the target terminal; the uplink data includes the target server IP address; Determine the target server's MAC address based on the target server's IP address; Uplink data is sent to the target server based on the target server's MAC address.
[0075] Specifically, the terminal can send uplink data to the server solely through the meter.
[0076] The target terminal sends uplink data to the instrument, which includes the target server IP address and the target terminal IP address. The instrument receives the uplink data sent by the target terminal, learns the target server IP address, determines the target server MAC address based on the target server IP address, and then sends the uplink data to the target server based on the target server MAC address.
[0077] The communication method provided in this application determines the MAC address of the target server through the instrument, enabling uplink data to be sent directly from the instrument to the target server. This achieves a direct connection between the instrument and the target server, eliminating the need for core network forwarding, reducing data interaction, and lowering the communication latency between the terminal and the server.
[0078] In some embodiments, determining the target server's MAC address based on the target server's IP address includes: The baseband board in the instrument broadcasts Address Resolution Protocol (ARP) request messages; the ARP request message carries the target server's IP address; The baseband board receives feedback messages sent by the target server; the feedback messages carry the target server's MAC address.
[0079] Specifically, the target terminal sends uplink data to the instrument, the baseband board in the instrument receives the uplink data, and the baseband board obtains the target server's MAC address based on the Address Resolution Protocol (ARP).
[0080] For example, the baseband board broadcasts an ARP request message carrying the target server's IP address. Non-target servers do not respond after receiving the ARP request message. After receiving the ARP request message, the target server sends a feedback message carrying the target server's MAC address to the baseband board. After receiving the feedback message from the target server, the baseband board learns the target server's MAC address.
[0081] The communication method provided in this application embodiment allows the instrument to obtain the target server's MAC address using ARP, enabling uplink data to be sent directly from the instrument to the target server via the target server's MAC address. This achieves direct connection between the instrument and the server, eliminating the need for core network forwarding or the addition of new links, reducing hardware costs, minimizing data interaction, and lowering communication latency between the terminal and the server.
[0082] In some embodiments, sending uplink data to the target server based on the target server's MAC address includes: The baseband board in the instrument sends the uplink data and the target server's MAC address to the main control board in the instrument. The main control board receives the uplink data and the target server MAC address sent by the baseband board, and then sends the uplink data to the target server based on the target server MAC address.
[0083] Specifically, after determining the target server's MAC address, the baseband board in the instrument sends the uplink data and the target server's MAC address to the main control board in the instrument. The main control board then performs data conversion and sends the uplink data to the target server based on the target server's MAC address.
[0084] In some embodiments, sending uplink data and the target server MAC address to the main control board in the instrument includes: The baseband board removes the header of the uplink message sent by the target terminal; the uplink message carries uplink data; the header of the uplink message contains the TEID of the data transmission tunnel between the target terminal and the Layer 2 receiving uplink data. The baseband board encapsulates the uplink data into a second MAC field; the source MAC address in the second MAC field is the Layer 2 MAC address that receives the uplink data, and the destination MAC address in the second MAC field is the MAC address of the main control board; The baseband board sends the second MAC field and the target server's MAC address to the main control board.
[0085] Specifically, the baseband board in the instrument removes the header of the uplink message carrying the uplink data. This header is the General Packet Radio Service Tunneling Protocol User Plane (GTPU) header, which contains the TEID of the data transmission tunnel between the target terminal and the Layer 2 receiving uplink data.
[0086] The baseband board encapsulates the uplink data into a second MAC field. The source MAC address in the second MAC field is the Layer 2 MAC address of the receiving uplink data, and the destination MAC address in the second MAC field is the MAC address of the main control board. The second MAC field and the target server MAC address are then sent to the main control board.
[0087] The communication method provided in this application embodiment involves the baseband board in the instrument encapsulating uplink data into a second MAC field and sending it to the main control board. Simultaneously, the baseband board sends the obtained target server MAC address to the main control board, enabling the main control board to obtain the uplink data and the target server MAC address. This allows the main control board to send the uplink data to the target server, ensuring the smooth transmission of uplink data.
[0088] In some embodiments, sending uplink data to the target server based on the target server's MAC address includes: The main control board encapsulates the uplink data into a third MAC field; the source MAC address in the third MAC field is the MAC address of the main control board, and the destination MAC address in the third MAC field is the MAC address of the target server. The main control board sends the third MAC field to the target server.
[0089] Specifically, after the main control board in the instrument receives the uplink data (or the second MAC field) and the target server MAC address sent by the baseband board, it encapsulates the uplink data into a third MAC field, that is, changes the source MAC address to the MAC address of the main control board and changes the destination MAC address to the MAC address of the target server, so that the third MAC field can be sent to the target server.
[0090] The communication method provided in this application embodiment enables the main control board in the instrument to encapsulate the uplink data into a third MAC field and send it to the target server. This allows uplink data to be sent directly from the instrument to the target server without the need for core network forwarding or the addition of new links, thereby reducing hardware costs, reducing data interaction, and reducing communication latency between the terminal and the server.
