[0103] The embodiments of the present application provide a link establishment method, device, apparatus, system and storage medium, which improve the system simulator's support for the TCP / IP protocol by configuring IP data filtering rules on the system simulator, thereby improving the efficiency of IP link establishment.

[0104] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0105] The following is an explanation through specific embodiments.

[0106] Figure 1 is one of the flow diagrams of a link establishment method provided in an embodiment of the present application. The link establishment method can be applied to a test device in a test system. The test system can also include one or more system simulators and one or more terminals under test, such as Figure 2 As shown. Figure 1 As shown, the link establishment method may include the following steps:

[0107] Step 101, obtain first IP link information, the first IP link information is used to instruct the test device to establish a first IP link with the first tested terminal through a first system simulator, the first system simulator is used to characterize any one of one or more system simulators, and the first tested terminal is used to characterize any one of the one or more tested terminals.

[0108] Specifically, the first IP link information may refer to the IP link information required to be used when the first test case provided by the Testing and TestControl Notation (TTCN) test script is executed. The first test case may be a test case included in the TTCN test script. Wherein, the TTCN test script may include a set of protocol test cases specified by the 3rd Generation Partnership Project (3GPP), wherein each test case includes a part of the protocol specifications that need to be supported by the terminal under test, and many test cases need to test the protocol support of the terminal under test for IP multimedia data.

[0109] The first system simulator may refer to Figure 2 Any one of system simulators among system simulator 1, system simulator 2, ..., system simulator n.

[0110] The first terminal under test may refer to Figure 2 Any one of the tested terminal 1, the tested terminal 2, ..., the tested terminal m.

[0111] It is worth noting that the system simulator in the embodiment of the present application can be an NR system simulator, an LTE system simulator, or other system simulators. The present application does not limit the type of system simulator.

[0112] Step 102: Configure IP data filtering rules for the first system simulator according to the first IP link information.

[0113] Specifically, after the test device obtains the first IP link information, it can determine the first system simulator and the first terminal under test according to the first IP link information, and configure IP data filtering rules for the first system simulator, and the IP data filtering rules are used to filter the IP data between the test device and the first terminal under test. For example: filter the IP data sent from the terminal under test to the test device. Another example: filter the IP data sent from the test device to the terminal under test.

[0114] Step 103: Send the IP data filtering rules to the first system simulator.

[0115] Specifically, after configuring the IP data filtering rule, the test device can send the IP data filtering rule to the first system simulator, so that the first system simulator can filter the IP data transmitted between the test device and the first tested terminal according to the IP data filtering rule, for example, adding an Ethernet header to the uplink data and removing the Ethernet header from the downlink data.

[0116] It can be seen from the above embodiments that by obtaining the first IP link information, configuring IP data filtering rules for the first system simulator according to the first IP link information, and sending the IP data filtering rules to the first system simulator, the first system simulator can filter the IP data transmitted between the test device and the first terminal under test according to the IP data filtering rules, thereby improving the system simulator's support for the TCP / IP protocol and further improving the efficiency of IP link establishment.

[0117] Optionally, the first IP link information includes one or more of the following:

[0118] a cell identifier of the first system simulator;

[0119] IP protocol version number;

[0120] IP protocol type;

[0121] A local port, wherein the local port is a port used by the test device;

[0122] Local address, the local address is the IP address used by the test device;

[0123] A remote port, where the remote port is a port used by the first terminal under test;

[0124] A remote address, where the remote address is an IP address used by the first tested terminal;

[0125] IP security information.

[0126] Specifically, the cell identifier (Cell-Id) of the registered cell may refer to the identifier of the system simulator. For example, Cell-Id1 is the NR system simulator, and Cell-Id2 is the LTE simulator.

[0127] The IP protocol version number (IP Version) may refer to a version number such as the fourth version of the Internet Protocol (ie, IPv4) or the sixth version of the Internet Protocol (ie, IPv6).

[0128] The IP protocol type (Protocol Type) may refer to types such as User Datagram Protocol (UDP), TCP or Internet Control Message Protocol (ICMP).

[0129] The local port may refer to the port used by the test equipment, for example, the test equipment is a test computer (Personal Computer, PC).

[0130] The local address (Local Addr) may refer to the IP address used by the test device.

[0131] The remote port may refer to the port used by the terminal under test.

[0132] The remote address (Remote Addr) may refer to the IP address used by the terminal under test.

[0133] IP security information (IPSEC) can include algorithm and key information.

[0134] It can be seen from the above embodiments that the first IP link information includes IP protocol information, local information and remote information required for test case execution, so that it is convenient to configure IP data filtering rules for the system simulator based on these information, thereby improving the reliability of IP link establishment.

[0135] Optionally, the IP data filtering rules in the above step 102 include uplink data filtering rules and downlink data filtering rules, the uplink data filtering rules are used to filter the IP data sent by the first terminal under test to the test device, and the downlink data filtering rules are used to filter the IP data sent by the test device to the first terminal under test.

[0136] Specifically, when the test device configures IP data filtering rules for the first system simulator, it needs to configure uplink data filtering rules and downlink data filtering rules, so that the first system simulator can filter uplink IP data according to the uplink data filtering rules, and filter downlink IP data according to the downlink data filtering rules.

[0137] For example, the first system simulator filters the uplink IP data according to the uplink data filtering rule, which may include:

[0138] Check the source and destination addresses in the uplink data packet;

[0139] If the data is encrypted, check the IP security information (IPSEC);

[0140] If the data is not encrypted, check the source and destination ports, as well as the protocol type;

[0141] If all the above information matches, the upstream IP data will be sent to the test device after adding the Ethernet header;

[0142] If the information does not match, the upstream IP data is directly discarded.

[0143] For another example, when the first system simulator filters the downstream IP data according to the downstream data filtering rule, it may include:

[0144] Check the source and destination addresses in the downlink data packet;

[0145] If the data is encrypted, check the IP security information (IPSEC);

[0146] If the data is not encrypted, check the source and destination ports, as well as the protocol type;

[0147] If all the above information matches, the downlink IP data is sent to the first tested terminal after removing the Ethernet header;

[0148] If the information does not match, the downstream IP data is directly discarded.

[0149] It can be seen from the above embodiments that the IP data filtering rules may include uplink data filtering rules and downlink data filtering rules. This makes it easy for the first system simulator to filter the uplink IP data according to the uplink data filtering rules, and to filter the downlink IP data according to the downlink data filtering rules, thereby improving the system simulator's support for the TCP / IP protocol and further improving the efficiency of IP link establishment.

[0150] Optionally, the link establishment method provided in the embodiment of the present application further includes:

[0151] A local link corresponding to the first IP link is established according to local information in the first IP link information, where the local information includes the local port and the local address.

[0152] Specifically, the test device may establish a local link corresponding to the first IP link according to the local information included in the first IP link information, such as a local port (Local Port) and a local address (Local Addr), and start an IP data receiving and sending thread.

[0153] In addition, the test device may also configure IPSEC of the local link according to the IP security information (IPSEC) included in the first IP link information.

[0154] It is worth noting that the test device in the embodiment of the present application comes with a TCP / IP protocol stack. Since the TTCN test script can only send and receive user data, that is, the data cannot contain TCP / User Datagram Protocol (UDP) header and IP header information, the TCP / IP protocol stack will filter the IP data transmitted between the test device and the first device under test. For example: the TCP / IP protocol stack adds a TCP / UDP header, an IP header, and an Ethernet header to the downlink data and sends it to the first system simulator; removes the TCP / UDP header, IP header, and Ethernet header from the received uplink data and sends it to the TTCN test script.

[0155] It can be seen from the above embodiments that in addition to configuring IP data filtering rules for the first system simulator, the test device also needs to establish a local link corresponding to the first IP link based on the local information contained in the first IP link information, such as: local port (Local Port) and local address (Local Addr). This can ensure IP data transmission between the test device and the first device under test and improve the efficiency of data transmission.

[0156] Optionally, the link establishment method provided in the embodiment of the present application further includes:

[0157] If it is determined according to the first IP link information that the first IP link is an IP link established for the first time by the test device and the first terminal under test through the first system simulator, then generating cell switching indication information for indicating the first IP link;

[0158] sending the cell switching indication information to the first system simulator;

[0159] receiving a media access control (MAC) address learning request message sent by the first system simulator according to the cell switching indication information;

[0160] A MAC address learning response message is sent to the first system simulator, where the MAC address learning response message includes the MAC address of the test device.

[0161] Specifically, when determining whether the first IP link is an IP link established for the first time, the test device may compare the established historical IP links.

[0162] For example, the system simulator identifier in the first IP link information is Cell-Id2, and the IP address of the first terminal under test is 192.168.0.2;

[0163] The historical IP links that are stored locally include:

[0164] IP link 1: The system simulator is identified as Cell-Id1, and the IP address of the terminal under test is 192.168.0.2;

[0165] IP link 2: The system simulator is identified as Cell-Id1, and the IP address of the terminal under test is 193.168.0.2;

[0166] IP link 3: The system simulator is identified as Cell-Id1, and the IP address of the terminal under test is 203.168.0.2;

[0167] IP link 4: The system simulator is identified as Cell-Id1, and the IP address of the terminal under test is 204.168.0.2;

[0168] By comparison, the IP address in the first IP link information is the same as the IP address in IP link 1, but the system simulator identifier is different, indicating that the system simulator has switched, that is, the first IP link established at this time is the first IP link established, and it is necessary to instruct the switched system simulator to initiate the MAC address learning process.

[0169] Among them, for the MAC address learning request message in the MAC address learning process, the type of MAC address learning request message corresponding to different IP protocol versions (IP Version) is different. For example, the MAC address learning request message corresponding to IPv4 is an Address Resolution Protocol (ARP) request message, and the MAC address learning request message corresponding to IPv6 is a Neighbor Solicitation (NS) message.

[0170] For the MAC address learning response message in the MAC address learning process, the type of MAC address learning response message corresponding to different IP protocol versions (IPVersion) is different. For example, the MAC address learning response message corresponding to IPv4 is an ARP response message, and the MAC address learning response message corresponding to IPv6 is a neighbor advertisement (NeighborAdvertisement, NA) message.

[0171] It can be seen from the above embodiments that when the test device determines that the first IP link is an IP link established for the first time, it can instruct the corresponding system simulator to initiate a MAC address learning process, so that the system simulator can add the MAC address of the test device to the Ethernet header when filtering data, thereby ensuring the IP data transmission between the test device and the first device under test and improving the reliability of data transmission.

[0172] Figure 3 This is a flow chart of a link establishment method provided in an embodiment of the present application. The link establishment method is applied to a system simulator in a test system. The test system also includes a test device and one or more terminals under test. Figure 3 As shown, the link establishment method may include the following steps:

[0173] Step 301, receive the IP data filtering rules sent by the test device, where the IP data filtering rules are the filtering rules configured by the test device for the system simulator based on the first IP link information, where the first IP link information is used to instruct the test device to establish a first IP link with the first tested terminal through the system simulator, where the first tested terminal is used to represent any one of the one or more tested terminals.

[0174] Specifically, the system simulator may refer to Figure 2 Any one of system simulators among system simulator 1, system simulator 2, ..., system simulator n.

[0175] The first terminal under test may refer to Figure 2 Any one of the tested terminal 1, the tested terminal 2, ..., the tested terminal m.

[0176] It is worth noting that the system simulator in the embodiment of the present application can be an NR system simulator, an LTE system simulator, or other system simulators. The present application does not limit the type of system simulator.

[0177] In addition, the first IP link information may refer to the IP link information required to be used when the first test case provided by the TTCN test script is executed. The first test case may be a test case included in the TTCN test script. The TTCN test script may include a set of protocol test cases specified by 3GPP, each of which includes a portion of protocol specifications that need to be supported by the terminal under test, and many test cases need to test the protocol support of the terminal under test for IP multimedia data.

[0178] The first IP link information includes one or more of the following:

[0179] a cell identifier of the first system simulator;

[0180] IP protocol version number;

[0181] IP protocol type;

[0182] A local port, wherein the local port is a port used by the test device;

[0183] Local address, the local address is the IP address used by the test device;

[0184] A remote port, where the remote port is a port used by the first terminal under test;

[0185] A remote address, where the remote address is an IP address used by the first tested terminal;

[0186] IP security information.

[0187] Specifically, the cell identifier (Cell-Id) of the registered cell may refer to the identifier of the system simulator. For example, Cell-Id1 is the NR system simulator, and Cell-Id2 is the LTE simulator.

[0188] The IP protocol version number (IP Version) may refer to a version number such as the fourth version of the Internet Protocol (ie, IPv4) or the sixth version of the Internet Protocol (ie, IPv6).

[0189] The IP protocol type (Protocol Type) may refer to types such as User Datagram Protocol (UDP), TCP or Internet Control Message Protocol (ICMP).

[0190] The local port may refer to the port used by the test equipment, for example, the test equipment is a test computer (Personal Computer, PC).

[0191] The local address (Local Addr) may refer to the IP address used by the test device.

[0192] The remote port may refer to the port used by the terminal under test.

[0193] The remote address (Remote Addr) may refer to the IP address used by the terminal under test.

[0194] IP security information (IPSEC) can include algorithm and key information.

[0195] Step 302: Filter the IP data transmitted between the test device and the first tested terminal according to the IP data filtering rule.

[0196] Specifically, the system simulator can filter the IP data between the test device and the first terminal under test according to the IP data filtering rule, for example: filtering the IP data sent from the terminal under test to the test device, or for another example: filtering the IP data sent from the test device to the terminal under test.

[0197] It can be seen from the above embodiments that the system simulator filters the IP data transmitted between the test device and the first terminal under test according to the IP data filtering rules sent by the receiving test device, thereby improving the system simulator's support for the TCP / IP protocol and further improving the efficiency of IP link establishment.

[0198] Optionally, the IP data filtering rules include uplink data filtering rules and downlink data filtering rules, the uplink data filtering rules are used to filter the IP data sent by the first terminal under test to the test device, and the downlink data filtering rules are used to filter the IP data sent by the test device to the first terminal under test.

[0199] The filtering of the IP data transmitted between the test device and the first tested terminal according to the IP data filtering rule includes:

[0200] Filtering the IP data sent by the first tested terminal to the test device according to the uplink data filtering rule;

[0201] The IP data sent by the test device to the first tested terminal is filtered according to the downlink data filtering rule.

[0202] Specifically, the IP data filtering rules include uplink data filtering rules and downlink data filtering rules. The system simulator can filter the IP data sent by the first tested terminal to the test device according to the uplink data filtering rules, and the system simulator can filter the IP data sent by the test device to the first tested terminal according to the downlink data filtering rules.

[0203] For example, when the first system simulator filters the uplink IP data according to the uplink data filtering rule, it may include:

[0204] Check the source and destination addresses in the uplink data packet;

[0205] If the data is encrypted, check the IP security information (IPSEC);

[0206] If the data is not encrypted, check the source and destination ports, as well as the protocol type;

[0207] If all the above information matches, the upstream IP data will be sent to the test device after adding the Ethernet header;

[0208] If the information does not match, the upstream IP data is directly discarded.

[0209] For another example, when the first system simulator filters the downstream IP data according to the downstream data filtering rule, it may include:

[0210] Check the source and destination addresses in the downlink data packet;

[0211] If the data is encrypted, check the IP security information (IPSEC);

[0212] If the data is not encrypted, check the source and destination ports, as well as the protocol type;

[0213] If all the above information matches, the downlink IP data is sent to the first tested terminal after removing the Ethernet header;

[0214] If the information does not match, the downstream IP data is directly discarded.

[0215] It can be seen from the above embodiments that the system simulator filters the uplink IP data according to the uplink data filtering rules, and filters the downlink IP data according to the downlink data filtering rules, thereby improving the system simulator's support for the TCP / IP protocol and further improving the efficiency of IP link establishment.

[0216] Optionally, the link establishment method provided in the embodiment of the present application further includes:

[0217] If the cell switching indication information sent by the test device for indicating the first IP link is received, a media access control MAC address learning request message is generated according to the cell switching indication information;

[0218] Sending the MAC address learning request message to the test device;

[0219] Receiving a MAC address learning response message sent by the test device, wherein the MAC address learning response message includes the MAC address of the test device;

[0220] The MAC address of the test device is added to the IP data transmitted between the test device and the first terminal under test.

[0221] Specifically, after receiving the cell switching indication information sent by the test device, the system simulator will initiate a MAC address learning process to the test device according to the cell switching indication information.

[0222] Among them, for the MAC address learning request message in the MAC address learning process, the MAC address learning request message type corresponding to different IP protocol versions (IP Version) is different. For example, the MAC address learning request message corresponding to IPv4 is an ARP request message, and the MAC address learning request message corresponding to IPv6 is NS.

[0223] For the MAC address learning response message in the MAC address learning process, the MAC address learning response message type corresponding to different IP protocol versions (IPVersion) is different. For example, the MAC address learning response message corresponding to IPv4 is an ARP response message, and the MAC address learning response message corresponding to IPv6 is an NA message.

[0224] For example: IPV4 uses the first tested terminal address in the upstream filtering rule as the source address, uses the test device address as the destination address, simulates sending ARP request messages, and learns the MAC address of the test device. After obtaining the MAC address of the test device, the upstream IPv4 data can be successfully sent to the test device. The TCP / IP protocol stack on the test device will reply with an ARP response message and update the ARP table on the test device, so that the downstream IPv4 data will be sent to the corresponding system simulator according to the ARP table.

[0225] Another example: IPv6 uses the address of the tested terminal in the upstream filtering rule as the source address, uses the test device address as the destination address, simulates sending a neighbor request message (NS), and learns the MAC address of the test device. After obtaining the MAC address of the test device, the upstream IPv6 data can be successfully sent to the test device. The TCP / IP protocol stack on the test device will reply with a neighbor response message (NA) to update the IPv6 neighbor table of the test device. Similarly, the downstream IPv6 data will be sent to the corresponding system simulator according to the neighbor table.

[0226] It can be seen from the above embodiments that after the system simulator receives the cell switching indication information for indicating the first IP link, it can initiate a MAC address learning process to the test device and add the learned MAC address of the test device to the Ethernet header, thereby ensuring the IP data transmission between the test device and the first device under test and improving the reliability of data transmission.

[0227] The following uses the NR system simulator and the LTE system simulator as examples (i.e., Figures 4 to 6 ) to specifically describe the implementation process of the above link establishment.

[0228] like Figure 4 As shown, the test equipment includes a TTCN test script, an IP link establishment module, and a TCP / IP protocol stack; the system simulator includes an IP data filtering module. The IP link establishment module can be a functional module of the test equipment. The IP data filtering module can be a functional module of the system simulator.

[0229] TTCN test scripts contain a set of protocol test cases specified by 3GPP, each of which contains a part of the protocol specifications that the terminal under test needs to support, and most of the test cases need to test the protocol support of the terminal under test for IP multimedia data. TTCN test scripts can only send and receive user data, that is, the data cannot contain TCP / UDP header and IP header information.

[0230] The IP link establishment module is established by the link establishment method provided in the embodiment of the present application. On the one hand, it is used to receive data sent by the TTCN test script and send the data to the IP data filtering module on the corresponding IP link; on the other hand, it is used to receive data uploaded by the IP data filtering module and send the data to the TTCN test script on the corresponding IP link.

[0231] The TCP / IP protocol stack is the TCP / IP protocol stack that comes with the test device and can be called by other applications. The test device can be a test PC, and the IP address required for establishing an IP link needs to be configured on the test device.

[0232] The system simulator is responsible for simulating the base station, processing the signaling and IP data sent by the TTCN test script and sending them to the terminal under test through the air interface, and processing the air interface messages transmitted by the terminal under test and uploading them to the TTCN test script. The system simulator can be an NR system simulator, an LTE system simulator, or other systems that can simulate base stations. Figure 4 The system simulators listed in are NR system simulator and LTE system simulator.

[0233] The terminal under test, which is used to test the protocol support, will interact with the TTCN test script at the IP layer. The terminal under test needs to receive IP data with IP header and TCP / UDP header at the air interface.

[0234] The router is connected to the test equipment, the IP data filtering module on the LTE system simulator, and the IP data filtering module on the NR system simulator through the Ethernet port.

[0235] The IP data filtering module is responsible for filtering IP data packets in the network and performing cell switching operations.

[0236] like Figure 5 As shown, based on Figure 4 Test system shown:

[0237] (1) The TTCN test script sends the IP link information required for the execution of this use case to the IP link establishment module.

[0238] (2) The IP link establishment module splits the IP information into uplink filtering rules (local information pointing to the test device) and downlink filtering rules (remote information pointing to the terminal under test), and configures them to the IP data filtering module on the corresponding system simulator.

[0239] (3) The IP link establishment module establishes a local link monitor based on the local information in the IP information, configures the local link security information, starts the receiving thread, and waits for the arrival of the uplink data.

[0240] (4) The IP link establishment module checks the CellId field in the IP information to detect whether the current cell is a new cell (i.e., determines whether the IP link to be established is the first IP link established). If yes, it sends a cell switching instruction to the IP data filtering module.

[0241] (5) The IP data filter module receives the cell switching instruction and simulates the remote address to send a neighbor request message (IPv6) or an ARP request (IPv4) to learn the MAC address of the test device. In this way, when sending uplink data, the IP data filter module can fill in the MAC address of the test device in the Ethernet header and send the data to the test device correctly.

[0242] (6) After receiving the neighbor request message (Ipv6) or ARP request (Ipv4), the TCP / IP protocol stack of the test device will update the local neighbor table (Ipv6) or ARP table (Ipv4) and return the neighbor response message (Ipv6) or ARP response (Ipv4) carrying the MAC address of the test device. When sending downlink data, the TCP / IP protocol stack can find the MAC address of the corresponding IP data filter module according to the remote address, fill in the Ethernet header, and send the data to the correct IP data filter module.

[0243] (7) If you need to switch to another system simulator, just repeat the above process.

[0244] After the above link establishment process is completed, the TTCN test script can interact with the terminal under test at the IP layer. It can also support the situation where the TTCN test script only sends and receives user data, while the terminal under test needs to send and receive IP data. It can also complete the IP link switching between different system simulators in a short time.

[0245] like Figure 6 As shown, based on Figure 4 Test system shown:

[0246] (1) The terminal under test sends uplink IP data to the IP data filtering module through the air interface.

[0247] (2) IP data filtering module, filtering IP data according to the configured uplink filtering rules, including:

[0248] Check whether the address information in the IP header matches;

[0249] If the data is encrypted, check the IPSEC information;

[0250] If it is not encrypted, check the port and protocol type in the TCP / UDP header;

[0251] If the above information matches, the Ethernet header is added and the data is sent to the test device;

[0252] If the above information does not match, the data is discarded.

[0253] (3) After receiving the data, the TCP / IP protocol stack of the test device removes the Ethernet header, IP header, and TCP / UDP header and sends the user data to the IP link establishment module of the corresponding port.

[0254] (4) After receiving the user data, the IP link establishment module matches the corresponding IP link information and sends the user data to the TTCN test script.

[0255] (4) Downlink IP data processing corresponds to it.

[0256] It can be seen that in the IP link establishment scheme in the embodiment of the present application, the system simulator only needs to develop a small amount of IP data processing code to complete the entire IP link establishment and data transmission process, which greatly reduces the entry threshold of the system simulator for IP data testing. And according to actual tests, using the link switching between system simulators in the present invention, the link switching will be completed in a short time, which fully meets the needs of all current TTCN test cases. And for the switching test scenario in the connected state, it can effectively avoid data packet loss, and at the same time, it can also efficiently complete the switching action in the test scenario of repeated switching, that is, it can flexibly switch between multiple system simulators, and can ensure timeliness.
