[0074] The current solution is to directly use the multi-IMSI solution provided by the basic operator, so that operator A and operator B complete the inter-system connection in advance, and both parties jointly generate the same KI and OPC code data and provide their own IMSI. The Applet program that can dynamically switch the code IMSI is provided by the SIM card manufacturer and runs in the card. Please refer to Figure 1 Regarding the process of initiating eSIM operations locally under the existing technical architecture, take the use of the code number of a smart connected car in the UK market as an example: 1. The code number uses the initial IMSI#1; 2. The code number detects the UK network MCC 310 in the UK; 3. Applet checks the IMSI used in MCC 310 by the preset logic; 4. Applet checks that IMSI#1 cannot support MCC 310, while IMSI#2 can support MCC 310; 5. Applet switches and enables IMSI#2, and simultaneously switches the matching MSISDN and other parameters; 6. The code number uses IMSI#2 to access the Internet; 7. Applet continuously monitors the MCCMNC searched by the Modem.

[0075] The shortcomings of the existing solution include: 1. Multiple IMSIs in the code number belong to different operators. After the IMSI is stationed on the network, different operators will automatically assign IPs to the code numbers, which will lead to inconsistent IPs before and after the switching, and even IP conflicts. That is, code number A uses the IP 10.0.0.1 on operator 1, and code number B also uses the IP 10.0.0.1 on operator 2, which leads to IP conflicts in the IP communication of the host factory background; 2. Multiple IMSIs in the code number belong to different operators, resulting in inconsistent exports of private network APNs. The host factory needs to connect to the data exports of multiple operators for data aggregation; 3. Since the IMSI switching logic is completely controlled by the Applet on the terminal side, the host factory background cannot actually know the current IMSI in use. When it is necessary to send SMS or manage the code number, it is impossible to determine which operator's interface should be called for management; 4. To build a Multi-IMSI solution between operators, multiple operators need to connect at the core network level, which requires a certain degree of cooperation between operators. For the host factory, the operators that the host factory hopes to choose may not have cooperation, so there are problems with the timeliness and flexibility of the solution. In addition, for the intelligent connected car business, in addition to the most basic networking functions, higher requirements are also put forward for the solution. The data business of the intelligent connected car needs to be managed by APN and support private network channels and public network channels. The private network channel needs to be connected with the car company's backend through IPSec. For some car companies, the equipment needs to have a fixed IP on the private network APN link to support services such as server IP wake-up. Therefore, a solution is needed that can simultaneously support multi-region network coverage and switching, APN channel management, and fixed private network IP capabilities.

[0076] In an embodiment of the present invention, a method for global Internet of Vehicles based on Multi-IMSI is provided, which is applied in a network side system, wherein the network side system includes operator base stations and operator core networks, AAA systems and CMP systems in different countries, wherein the operator core networks in different countries share the same AAA system and CMP system; please refer to Figure 2 The global networking method of the Internet of Vehicles includes steps S10 to S30, which are described in detail below.

[0077] Step S10: When the intelligent connected vehicle enters the target country in the network side system, the IMSI on the intelligent connected vehicle is switched to a target IMSI supported by the target country.

[0078] In some embodiments, the intelligent connected vehicle includes a SIM card. The SIM card has a code number, and the code number includes multiple IMSIs, and the multiple IMSIs can be switched between each other.

[0079] In some embodiments, when the intelligent connected vehicle enters a target country in the network side system, the IMSI on the intelligent connected vehicle is switched to a target IMSI supported by the target country, including:

[0080] Switch the first IMSI on the smart connected vehicle to the second IMSI.

[0081] Among them, the first IMSI is the IMSI used by the smart connected vehicle before entering the target country, and the second IMSI is the target IMSI supported by the target country after the smart connected vehicle enters the target country. Assuming that the local country is China and the roaming country is the United Kingdom, when the smart connected vehicle accesses the Internet in China, the smart connected vehicle will use IMSI#1 supported by China. When the number follows the smart connected vehicle into the United Kingdom and detects that the current network environment is the British MCC310, the Applet will check the IMSI corresponding to MCC310 according to its pre-set logic. If the Applet checks that IMSI#1 cannot support MCC310, but IMSI#2 can support MCC310, the Applet will switch and enable IMSI#2, and simultaneously switch the matching MSISDN and other parameters. At the same time, the number will use IMSI#2 to access the Internet, and the Applet will continue to monitor the MCCMNC searched by the Modem.

[0082] Step S20: Activate the target IMSI supported by the target country in the intelligent connected vehicle, and send a network station request to the operator base station in the target country, and forward the network station request to the AAA system through the operator base station in the target country and the operator core network in the target country.

[0083] In some embodiments, assuming that the target country is the United Kingdom, the target IMSI supported by the United Kingdom in the intelligent connected vehicle is started, and a network station request is sent to the operator base station in the United Kingdom. The network station request is forwarded to the operator core network in the United Kingdom through the operator base station in the United Kingdom, and the operator core network in the United Kingdom forwards the network station request to the AAA system.

[0084] Step S30: When the AAA system receives the network stationing request, the AAA system and the CMP system allocate a corresponding IP to the intelligent connected vehicle with the target IMSI enabled, so that the intelligent connected vehicle uses the IP and the target IMSI to complete the network stationing in the operator core network of the target country.

[0085] In some embodiments, the CMP system includes an association relationship between multiple IMSIs in the code number, and the AAA system includes a mapping relationship between each IMSI and an IP. For example, the CMP system includes multiple IMSIs in the code number, and the IMSIs under the same code number have an association relationship. The AAA system includes a mapping relationship between different IMSIs and their assigned IPs. If IMSI#1 is used in China and IP1 is assigned, there is a mapping relationship between IMSI#1 and IP1, and the mapping relationship will be stored in the AAA system.

[0086] In some embodiments, the network side system includes a first operator base station and a first operator core network in a first country, wherein the first operator core network corresponds to an AAA system and a CMP system; please refer to Figure 3 Step S30 allocates a corresponding IP to the intelligent connected vehicle with the target IMSI enabled based on the AAA system and the CMP system, including steps S31 to S33, which are described in detail below.

[0087] Step S31: Determine whether the target IMSI has a corresponding IP according to the AAA system.

[0088] Step S32: If the target IMSI has a corresponding IP, the IP corresponding to the target IMSI is used as the IP of the intelligent connected vehicle that enables the target IMSI.

[0089] In this embodiment, the AAA system is used to detect whether the target IMSI has an already allocated IP. If the target IMSI has an already allocated IP, the already allocated IP is directly used as the IP of the intelligent connected vehicle that enables the target IMSI.

[0090] Step S33: If there is no corresponding IP for the target IMSI, an IP is allocated to the intelligent connected vehicle with the target IMSI enabled according to the AAA system and the predefined IP pool.

[0091] In this embodiment, if the target IMSI does not have an allocated IP, the AAA system will allocate an IP to the target IMSI according to a predefined IP pool, and use the allocated IP as the IP of the intelligent connected vehicle that enables the target IMSI.

[0092] In some embodiments, when the intelligent connected vehicle uses the IP and the target IMSI to complete the network stationing in the operator core network of the target country, the AAA system is used to update the usage status of the code number in the CMP system, wherein the usage status of the code number is that the current code number is used by the target IMSI. For example, the intelligent connected vehicle is allowed to use the allocated IP and the target IMSI to access the Internet in the UK. The AAA system will inform the CMP system that the current code number is the UK IMSI#2 in use, and all management work needs to be performed through the UK operator system.

[0093] In some embodiments, the network side system further includes a second operator base station and a second operator core network in a second country, wherein the first operator core network and the second operator core network share the same AAA system and CMP system, the first country is a country where the intelligent connected vehicle completes network stationing before entering the target country, the second country is the target country, the first country supports the first IMSI, and the second country supports the second IMSI; please refer to Figure 4 Step S30 allocates a corresponding IP to the intelligent connected vehicle with the target IMSI enabled based on the AAA system and the CMP system, including steps S34 to S38, which are described in detail below.

[0094] Step S34: Determine whether the second IMSI has a corresponding IP according to the AAA system.

[0095] In this embodiment, assuming that the first country is China, the second country is the United Kingdom, the first IMSI is IMSI#1, and the second IMSI is IMSI#2, after the intelligent connected vehicle completes the network stationing in China through IMSI#1, the code number follows the intelligent connected vehicle into the United Kingdom and switches its IMSI to IMSI#2. At this time, it is necessary to determine whether there is a corresponding IP for IMSI#2 based on the AAA system.

[0096] Step S35: If the second IMSI has a corresponding IP, the IP corresponding to the second IMSI is used as the IP of the intelligent connected vehicle that enables the second IMSI.

[0097] In this embodiment, if there is a corresponding IP for IMSI#2, the IP corresponding to IMSI#2 is used as the IP for starting the intelligent connected vehicle of IMSI#2.

[0098] Step S36: If the second IMSI does not have a corresponding IP, the CMP system is called to detect whether the second IMSI supports the Multi-IMSI service.

[0099] In this embodiment, if there is no corresponding IP for IMSI#2, the CMP system is called to detect whether IMSI#2 supports Multi-IMSI service. Multi-IMSI service refers to a technology that allows a single SIM card to have multiple IMSIs, each of which represents a different operator network.

[0100] Step S37: If the second IMSI does not support the Multi-IMSI service, a corresponding IP is allocated to the intelligent connected vehicle that enables the second IMSI according to the AAA system and the predefined IP pool.

[0101] In this embodiment, if IMSI#2 does not support the Multi-IMSI service, a corresponding IP is allocated to the intelligent connected vehicle with IMSI#2 enabled according to the AAA system and the predefined IP pool.

[0102] Step S38: If the second IMSI supports the Multi-IMSI service, the IP of the IMSI associated with the second IMSI is used as the IP of the intelligent connected vehicle that enables the second IMSI.

[0103] In this embodiment, if IMSI#2 supports Multi-IMSI service, the IP of IMSI associated with IMSI#2 is used as the IP of the smart connected car with IMSI#2 enabled. For example, the code number of the smart connected car includes IMSI#1 and IMSI#2, and IMSI#1 and IMSI#2 are associated codes. In China, the smart connected car uses IMSI#1 and IP1 is allocated to the smart connected car. When the code number follows the smart connected car into the UK, the IMSI of the smart connected car is switched to IMSI#2. If IMSI#2 supports Multi-IMSI service, the IP of IMSI#1 associated with IMSI#2 is used as the IP of the smart connected car with IMSI#2 enabled.

[0104] In some embodiments, when the IP of the smart connected vehicle with the second IMSI enabled is determined, the network is completed in the operator core network of the second country according to the IP of the smart connected vehicle with the second IMSI enabled and the second IMSI; the AAA system is used to update the usage status of the code number in the CMP system, wherein the usage status of the code number is that the current code number is in use by the second IMSI. For example, the smart connected vehicle is allowed to use the allocated IP and IMSI#2 to access the Internet in the UK, and the AAA system will inform the CMP system that the current code number is the UK IMSI#2 in use, and all management work needs to be performed through the UK operator system.

[0105] In some embodiments, the network side system includes a first operator base station and a first operator core network in a first country, and a second operator base station and a second operator core network in a second country, wherein the first operator core network and the second operator core network share the same AAA system and CMP system, and when the network-enabled vehicle enters the second country after completing the network stationing in the first country, and enters the first country again from the second country, it also includes:

[0106] The IP assigned to the smart connected vehicle after completing the network stationing in the first country is used as the IP of the smart connected vehicle when it re-enters the first country from the second country.

[0107] For example, when in China, the smart connected car uses IMSI#1 and IP1 is assigned to the smart connected car. When the number follows the smart connected car into the UK, the IMSI of the smart connected car is switched to IMSI#2. If IMSI#2 supports Multi-IMSI services, the IP of IMSI#1 associated with IMSI#2 is used as the IP of the smart connected car with IMSI#2 enabled. At this time, if the smart connected car enters China again from the UK, the IP in China will use IP1 assigned to the smart connected car when it uses IMSI#1.

[0108] In some embodiments, the network side system also includes PGWs in different countries, wherein the PGWs in different countries share the same VPN Gateway; please refer to Figure 5 The vehicle network global networking method also includes steps S40 to S50, which are described in detail below.

[0109] Step S40: After the intelligent connected vehicle completes the network stationing in the operator core network of the target country using the IP and the target IMSI, the intelligent connected vehicle is used to send service data to the operator core network of the target country, and the service data is sent to the PGW of the target country.

[0110] In this embodiment, the PGW of the target country is responsible for forwarding the data traffic of the intelligent connected vehicle to the corresponding external data network, such as the public network or the OEM system.

[0111] Step S50: forward the business data to the VPN Gateway through the PGW of the target country, and send the business data to the OEM system through the VPN Gateway, so that the OEM system obtains the business data generated after the intelligent connected vehicle is stationed in the target country through the VPN Gateway and performs data analysis on the business data.

[0112] In this embodiment, the service data is forwarded to the VPN Gateway through the PGW of the target country, wherein the data exports of multiple operators are opened up through the VPN Gateway, and the data is aggregated at the export of a unified VPN Gateway, thus solving the problem of multiple data exports.

[0113] In some embodiments, in order to solve the problem that the current Multi-IMSI solution is not flexible enough and cannot fully meet the needs of the OEM, a solution is provided that can be quickly and flexibly implemented in the Internet of Vehicles scenario, while supporting multi-region / multi-operator networks, supporting unified private network data export and static IP capabilities. In view of the shortcomings of the prior art, this solution optimizes the shortcomings by introducing VPN Gateway, AAA system and CMP system. Through VPN Gateway, the data exports of multiple operators are connected, and the data is aggregated on the unified VPN Gateway export to solve the problem of multiple data exports. Through the AAA system, multiple operator networks are integrated, and the AAA system is used as a unified network access management platform to manage IMSIs and allocate IPs across multiple operators, thereby solving the problem that multiple operators' IPs cannot be unified and conflict. Through the CMP system, the SMSC gateways of multiple operators are connected, and with the help of the real-time IMSI network access status update of the AAA system, the CMP system provides unified code number management and SMS sending entry to solve the problem that multiple IMSI codes cannot be managed. In summary, this solution can achieve multi-region network coverage through IMSI switching, and can ensure that the IP of each number remains unchanged when the IMSI changes dynamically. For user OEM, there will be no management problems and conflicts caused by IP changes, and it can be considered that the same number is always in use. When the IMSI changes dynamically, the information of the IMSI in use can still be obtained in real time, and a unified interface is provided for user OEM to manage the number, and the user OEM does not need to pay attention to the changes in IMSI. The data export between different operators is opened up through VPN Gateway. For user OEM, even if the IMSI changes, the data export remains unified.

[0114] Please refer to Figure 6In some embodiments, a network-side system is provided, in which the above-mentioned multi-IMSI-based global Internet of Vehicles method is applied in the network-side system, and the network-side system includes operator base stations and operator core networks, AAA systems and CMP systems in different countries, wherein the operator core networks in different countries share the same AAA system and CMP system. For example, the network-side system includes operator 1 base station and operator 1 core network in the first country, and operator 2 base station and operator 2 core network in the second country, wherein the intelligent networked vehicle uses operator 1 IMSI in the first country, and the intelligent networked vehicle uses operator 2 IMSI in the second country. The operator 1 core network includes MNO1 SMSC and MNO1 OCS, and the operator 2 core network includes MNO2 SMSC and MNO2 OCS.

In addition, MNO2 PGW will also establish a connection with VPN Gateway through a data link, and VPN Gateway will send the service data obtained from MNO2 PGW to OEM Server.

[0115] Please refer to Figure 7 In an embodiment of the present invention, a network-side system applied in a vehicle networking scenario is provided, including operator base stations and operator core networks, AAA systems and CMP systems in different countries, wherein the operator core networks in different countries share the same AAA system and CMP system. For example, it includes a first operator base station and a first operator core network in a first country, and a second operator base station and a second operator core network in a second country, wherein the first operator core network and the second operator core network share the same AAA system and CMP system, which are described in detail below.

[0116] In some embodiments, the operator base station is used to receive a network station request sent by the intelligent connected vehicle and forward the network station request to the operator core network.

[0117] In some embodiments, the intelligent connected vehicle includes a SIM card. The SIM card has a code number, and the code number includes multiple IMSIs, and the multiple IMSIs can be switched between each other.

[0118] In some embodiments, when the intelligent connected vehicle enters a target country in the network side system, the IMSI on the intelligent connected vehicle is switched to a target IMSI supported by the target country, including:

[0119] Switch the first IMSI on the smart connected vehicle to the second IMSI.

[0120] Among them, the first IMSI is the IMSI used by the smart connected vehicle before entering the target country, and the second IMSI is the target IMSI supported by the target country after the smart connected vehicle enters the target country. Assuming that the local country is China and the roaming country is the United Kingdom, when the smart connected vehicle accesses the Internet in China, the smart connected vehicle will use IMSI#1 supported by China. When the number follows the smart connected vehicle into the United Kingdom and detects that the current network environment is the British MCC310, the Applet will check the IMSI corresponding to MCC310 according to its pre-set logic. If the Applet checks that IMSI#1 cannot support MCC310, but IMSI#2 can support MCC310, the Applet will switch and enable IMSI#2, and simultaneously switch the matching MSISDN and other parameters. At the same time, the number will use IMSI#2 to access the Internet, and the Applet will continue to monitor the MCCMNC searched by the Modem.

[0121] In some embodiments, the operator core network is used to receive a network station request sent by the operator base station, forward the network station request to the AAA system, and receive the IP of the smart connected vehicle fed back by the AAA system, so that the smart connected vehicle uses the IP and its IMSI to complete the network station in the operator core network.

[0122] In some embodiments, assuming that the target country is the United Kingdom, the target IMSI supported by the United Kingdom in the intelligent connected vehicle is started, and a network station request is sent to the operator base station in the United Kingdom. The network station request is forwarded to the operator core network in the United Kingdom through the operator base station in the United Kingdom, and the operator core network in the United Kingdom forwards the network station request to the AAA system.

[0123] In some embodiments, the AAA system is used to receive a network access request sent by the operator's core network, and determine whether there is a corresponding IP for the IMSI on the intelligent connected vehicle. If there is a corresponding IP for the IMSI, the IP corresponding to the IMSI is used as the IP of the intelligent connected vehicle. If there is no corresponding IP for the IMSI, the CMP system is called to detect whether the IMSI supports Multi-IMSI services, and an IP is allocated to the intelligent connected vehicle based on the detection results fed back by the CMP system.

[0124] In some embodiments, the CMP system includes an association relationship between multiple IMSIs in the code number, and the AAA system includes a mapping relationship between each IMSI and an IP. For example, the CMP system includes multiple IMSIs in the code number, and the IMSIs under the same code number have an association relationship. The AAA system includes a mapping relationship between different IMSIs and their assigned IPs. If IMSI#1 is used in China and IP1 is assigned, there is a mapping relationship between IMSI#1 and IP1, and the mapping relationship will be stored in the AAA system.

[0125] In some embodiments, the network side system includes a first operator base station and a first operator core network in a first country, wherein the first operator core network corresponds to an AAA system and a CMP system; please refer to Figure 3 , based on the AAA system and the CMP system, the corresponding IP is allocated to the intelligent connected vehicle with the target IMSI enabled, which is achieved through the following actions, which are described in detail below.

[0126] The AAA system determines whether there is a corresponding IP for the target IMSI. If there is a corresponding IP for the target IMSI, the IP corresponding to the target IMSI is used as the IP of the smart connected vehicle that enables the target IMSI. If there is no corresponding IP for the target IMSI, an IP is allocated to the smart connected vehicle that enables the target IMSI based on the AAA system and the predefined IP pool.

[0127] In this embodiment, the AAA system is used to detect whether the target IMSI has an already allocated IP. If the target IMSI has an already allocated IP, the already allocated IP is directly used as the IP of the intelligent connected vehicle that enables the target IMSI.

[0128] In this embodiment, if the target IMSI does not have an allocated IP, the AAA system will allocate an IP to the target IMSI according to a predefined IP pool, and use the allocated IP as the IP of the intelligent connected vehicle that enables the target IMSI.

[0129] In some embodiments, when the intelligent connected vehicle uses the IP and the target IMSI to complete the network stationing in the operator core network of the target country, the AAA system is used to update the usage status of the code number in the CMP system, wherein the usage status of the code number is that the current code number is used by the target IMSI. For example, the intelligent connected vehicle is allowed to use the allocated IP and the target IMSI to access the Internet in the UK. The AAA system will inform the CMP system that the current code number is the UK IMSI#2 in use, and all management work needs to be performed through the UK operator system.

[0130] In some embodiments, the network side system further includes a second operator base station and a second operator core network in a second country, wherein the first operator core network and the second operator core network share the same AAA system and CMP system, the first country is the country where the intelligent connected vehicle completes the network stationing before entering the target country, the second country is the target country, the first country supports the first IMSI, and the second country supports the second IMSI; please return to reference Figure 4 , based on the AAA system and the CMP system, the corresponding IP is allocated to the intelligent connected vehicle with the target IMSI enabled, which is achieved through the following actions, which are described in detail below.

[0131] Determine whether there is a corresponding IP for the second IMSI according to the AAA system. If there is a corresponding IP for the second IMSI, the IP corresponding to the second IMSI is used as the IP of the smart connected vehicle with the second IMSI enabled. If there is no corresponding IP for the second IMSI, call the CMP system to detect whether the second IMSI supports the Multi-IMSI service. If the second IMSI does not support the Multi-IMSI service, the corresponding IP is allocated to the smart connected vehicle with the second IMSI enabled according to the AAA system and the predefined IP pool. If the second IMSI supports the Multi-IMSI service, the IP of the IMSI associated with the second IMSI is used as the IP of the smart connected vehicle with the second IMSI enabled.

[0132] In this embodiment, assuming that the first country is China, the second country is the United Kingdom, the first IMSI is IMSI#1, and the second IMSI is IMSI#2, then after the intelligent connected vehicle completes the network stationing in China through IMSI#1, the code number follows the intelligent connected vehicle into the United Kingdom, and switches its IMSI to IMSI#2. At this time, it is necessary to determine whether there is a corresponding IP for IMSI#2 according to the AAA system. If there is a corresponding IP for IMSI#2, the IP corresponding to IMSI#2 is used as the IP of the intelligent connected vehicle that starts IMSI#2. If there is no corresponding IP for IMSI#2, the CMP system is called to detect whether IMSI#2 supports Multi-IMSI services. Among them, Multi-IMSI service refers to a technology that allows a single SIM card to have multiple IMSIs, and each IMSI represents a different operator network. If IMSI#2 does not support Multi-IMSI service, the corresponding IP is allocated to the intelligent connected vehicle that enables IMSI#2 according to the AAA system and the predefined IP pool.

[0133] In this embodiment, if IMSI#2 supports Multi-IMSI service, the IP of IMSI associated with IMSI#2 is used as the IP of the smart connected car with IMSI#2 enabled. For example, the code number of the smart connected car includes IMSI#1 and IMSI#2, and IMSI#1 and IMSI#2 are associated codes. In China, the smart connected car uses IMSI#1 and IP1 is allocated to the smart connected car. When the code number follows the smart connected car into the UK, the IMSI of the smart connected car is switched to IMSI#2. If IMSI#2 supports Multi-IMSI service, the IP of IMSI#1 associated with IMSI#2 is used as the IP of the smart connected car with IMSI#2 enabled.

[0134] In some embodiments, when the IP of the smart connected vehicle with the second IMSI enabled is determined, the network is completed in the operator core network of the second country according to the IP of the smart connected vehicle with the second IMSI enabled and the second IMSI; the AAA system is used to update the usage status of the code number in the CMP system, wherein the usage status of the code number is that the current code number is in use by the second IMSI. For example, the smart connected vehicle is allowed to use the allocated IP and IMSI#2 to access the Internet in the UK, and the AAA system will inform the CMP system that the current code number is the UK IMSI#2 in use, and all management work needs to be performed through the UK operator system.

[0135] In some embodiments, the network side system includes a first operator base station and a first operator core network in a first country, and a second operator base station and a second operator core network in a second country, wherein the first operator core network and the second operator core network share the same AAA system and CMP system, and when the network-enabled vehicle enters the second country after completing the network stationing in the first country, and enters the first country again from the second country, it also includes:

[0136] The IP assigned to the smart connected vehicle after completing the network stationing in the first country is used as the IP of the smart connected vehicle when it re-enters the first country from the second country.

[0137] For example, when in China, the smart connected car uses IMSI#1 and IP1 is assigned to the smart connected car. When the number follows the smart connected car into the UK, the IMSI of the smart connected car is switched to IMSI#2. If IMSI#2 supports Multi-IMSI services, the IP of IMSI#1 associated with IMSI#2 is used as the IP of the smart connected car with IMSI#2 enabled. At this time, if the smart connected car enters China again from the UK, the IP in China will use IP1 assigned to the smart connected car when it uses IMSI#1.

[0138] In some embodiments, the network side system also includes PGWs in different countries, wherein the PGWs in different countries share the same VPN Gateway; please refer to Figure 5 , the network side system can also implement the following actions, which are described in detail below.

[0139] When the intelligent connected vehicle completes the network stationing in the operator core network of the target country using the IP and the target IMSI, the intelligent connected vehicle sends service data to the operator core network of the target country, and sends the service data to the PGW of the target country. The PGW of the target country forwards the service data to the VPN Gateway, and the service data is sent to the OEM system through the VPN Gateway, so that the OEM system obtains the service data generated by the intelligent connected vehicle after the network stationing in the target country through the VPN Gateway and performs data analysis on the service data.

[0140] In this embodiment, the PGW of the target country is responsible for forwarding the data traffic of the intelligent connected vehicle to the corresponding external data network, such as the public network or the OEM system.

[0141] In this embodiment, the service data is forwarded to the VPN Gateway through the PGW of the target country, wherein the data exports of multiple operators are opened up through the VPN Gateway, and the data is aggregated at the export of a unified VPN Gateway, thus solving the problem of multiple data exports.

[0142] In some embodiments, in order to solve the problem that the current Multi-IMSI solution is not flexible enough and cannot fully meet the needs of the OEM, a solution is provided that can be quickly and flexibly implemented in the Internet of Vehicles scenario, while supporting multi-region / multi-operator networks, supporting unified private network data export and static IP capabilities. In view of the shortcomings of the prior art, this solution optimizes the shortcomings by introducing VPN Gateway, AAA system and CMP system. Through VPN Gateway, the data exports of multiple operators are connected, and the data is aggregated on the unified VPN Gateway export to solve the problem of multiple data exports. Through the AAA system, multiple operator networks are integrated, and the AAA system is used as a unified network access management platform to manage IMSIs and allocate IPs across multiple operators, thereby solving the problem that multiple operators' IPs cannot be unified and conflict. Through the CMP system, the SMSC gateways of multiple operators are connected, and with the help of the real-time IMSI network access status update of the AAA system, the CMP system provides unified code number management and SMS sending entry to solve the problem that multiple IMSI codes cannot be managed. In summary, this solution can achieve multi-region network coverage through IMSI switching, and can ensure that the IP of each number remains unchanged when the IMSI changes dynamically. For user OEM, there will be no management problems and conflicts caused by IP changes, and it can be considered that the same number is always in use. When the IMSI changes dynamically, the information of the IMSI in use can still be obtained in real time, and a unified interface is provided for user OEM to manage the number, and the user OEM does not need to pay attention to the changes in IMSI. The data export between different operators is opened up through VPN Gateway. For user OEM, even if the IMSI changes, the data export remains unified.

[0143] The CMP system is used to detect whether the IMSI supports the Multi-IMSI service and feed back the detection result to the AAA system.
