[0038] The following is a more detailed description of the QoS performance detection system and method based on 5G customized private network adaptive adjustment of the present invention in conjunction with the schematic diagram, which shows the preferred embodiment of the present invention. It should be understood that those skilled in the art can modify the present invention described herein and still achieve the beneficial effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation of the present invention.

[0039] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are in very simplified form and in non-precise proportions, and are only used to facilitate and clearly assist in illustrating the purpose of the embodiments of the present invention.

[0040] like Figure 1 As shown, the embodiment of the present invention proposes a customized private network, a core network, a private network performance monitoring terminal and a QoS gateway.

[0041] The customized private network, the core network and the private network performance monitoring terminal are connected in pairs.

[0042] The private network performance monitoring terminal is used to obtain relevant data parameters and transmit the data parameters to the core network.

[0043] The data parameters include wireless signal environment information (such as RSRP, SINR, and PCI, etc.), location information, and various simulated service rates.

[0044] The core network is used to forward the data parameters to the customized private network.

[0045] The customized private network includes the QoS gateway, which is used to receive the data parameters transmitted by the core network, and formulate and store corresponding simulation QoS policies based on the data parameters.

[0046] When the private network performance monitoring terminal transmits real business information to the QoS gateway, the QoS gateway configures the corresponding simulated QoS policy according to the real business information and feeds it back to the core network.

[0047] To sum up, since the simulated QoS strategy is formulated based on relevant data parameters, when real business occurs, the corresponding simulated QoS strategy can be adjusted based on the same data parameters as the real business and input into the core network for use, thereby solving the problem of network resource waste caused by the inability to dynamically adjust the QoS strategy in the existing technology.

[0048] See also Figure 2In other embodiments, the private network performance monitoring terminal includes a wireless signal detection module, a location information acquisition module, various service simulation modules and a data reporting module.

[0049] The wireless signal detection module is used to identify wireless signal environment information; the location information acquisition module is used to identify location information, and the simulation of various types of business modules is used to identify various types of simulation business rates. The input end of the data reporting module is respectively connected to the wireless signal detection module, the location information acquisition module and the simulation of various types of business modules, and the output end is connected to the core network for transmitting the data parameters to the core network.

[0050] By setting up a wireless signal detection module, a location information acquisition module and simulating various business modules, the wireless signal environment information, location information and simulated business rate are obtained respectively, and by setting up a data reporting module, the data parameters are transmitted to the core network, and then transmitted to the QoS gateway by the core network, so that the QoS gateway can formulate corresponding QoS strategies based on the data parameters.

[0051] See also Figure 3 In a further embodiment, the QoS gateway includes a simulation business server module, a data storage module, a QoS policy customization module, a real business query module and a return QoS policy module.

[0052] The simulation service server module is connected with the simulation service modules for simulating various services.

[0053] The data storage module is used to store the data parameters, so as to facilitate the comparison of the data parameters in subsequent real business and retrieve the matching simulation QoS policy.

[0054] The QoS policy customization module is used to formulate the corresponding QoS policy according to the data parameters.

[0055] The real business query module is used to query whether it is a real business type. If so, a simulated QoS policy matching the real business data parameters is configured.

[0056] The returning QoS policy module is used to return the corresponding QoS policy to the core network.

[0057] Specifically, the customized private network also includes a business server.

[0058] The service server is bidirectionally connected to the QoS gateway, and is used for the real service query module to confirm the service type according to the destination address and port reported by the real service, and to determine whether it is a real service according to the reported destination address and port.

[0059] Among them, the customized private network also includes edge UPF.

[0060] The edge UPF, service server and QoS gateway are connected in pairs; and the edge UPF is also connected to the private network performance monitoring terminal.

[0061] In other embodiments, the core network includes a policy control network element and an AMF.

[0062] The policy control network element is bidirectionally connected to the QoS gateway for querying and receiving the QoS policy.

[0063] The AMF is bidirectionally connected to the private network performance monitoring terminal, and is used to receive the PDU request of the private network performance monitoring terminal and establish a PDU bearer according to the corresponding QoS policy configuration.

[0064] To sum up, the specific operation process of this system can be divided into the following steps:

[0065] 1) When real business is required, the core network first sends the location information of the private network performance monitoring terminal, the business destination address and the port to the QoS gateway when establishing the PDU bearer;

[0066] 2) The QoS gateway confirms the real service type with the service server through the destination address and port information;

[0067] 3) The QoS gateway queries the QoS policy in the current QoS table based on the type information of the real service and the location information of the private network performance monitoring terminal;

[0068] 4) The QoS gateway sends the QoS policy to the policy control network element;

[0069] 5) The core network establishes PDU bearer according to the configuration in the policy control network element.

[0070] The present invention uses a customized QoS strategy each time, and when the private network performance monitoring terminal is performing real business, it can guarantee the normal use of the business to the greatest extent and the reasonable use of core network resources to a certain extent.

[0071] Embodiment 2

[0072] See also Figure 4 This embodiment adds a method for adaptively adjusting QoS performance based on a 5G customized private network on the basis of the first embodiment, which specifically includes the following steps:

[0073] Before establishing a PDU session, the private network performance monitoring terminal sends service information to the QoS gateway;

[0074] The QoS gateway queries the service type according to the service information;

[0075] Match the corresponding QoS method in the current environment and feed it back to the core network;

[0076] The core network configures the QoS policy for this session based on the returned result and establishes a PDU bearer.

[0077] In this embodiment, through each customized QoS strategy, the private network performance monitoring terminal can maximize the guarantee of normal service use and reasonable use of core network resources to a certain extent when performing real services, thereby effectively avoiding waste of network resources.

[0078] See also Figure 5 , further, the matching method of the QoS method includes the following technical steps:

[0079] Search the wireless network data status at this time and place reported by the performance monitoring terminal of the private network of the QoS gateway and the data rate of the same type as the actual service;

[0080] Determine whether the wireless network data status at this time and place meets the actual service rate requirements. If so, use non-GBR QoS flow for PDU session to perform data services; if not, use GBR QoS flow for PDU session to perform data services.

[0081] Among them, when using non-GBR QoS flow, that is, the flow rate is not guaranteed, the resource requirements are low, and only a small amount of control information is transmitted, so less network resources are consumed and the network burden can be reduced.

[0082] See also Figure 6 In other embodiments, the QoS policy configuration method includes the following technical steps:

[0083] The configuration method of the QoS policy includes the following technical steps:

[0084] Preset the real business indicators and the target address and port mapping table of the corresponding business in the QoS gateway;

[0085] The indicator data of the simulated service is obtained through the simulated service terminal test and stored in the QoS gateway, and a corresponding service relationship data indicator table of the real service and the simulated service data indicators is generated;

[0086] When the private network performance monitoring terminal initiates a real service, the QoS gateway obtains the network status of the current simulation service by mapping the active service type in the table and querying the service relationship data indicator table;

[0087] Through the indicator requirements in the mapping table and the simulated business situation in the business relationship data indicator table at this time, the corresponding type of QoS policy configuration that needs to be used is obtained.

[0088] The service information includes location information, destination address and port information.

[0089] See also Figure 7 In summary, the QoS gateway in this embodiment includes a storage unit, a configuration sending unit and a judgment unit.

[0090] The storage unit is used to store the corresponding list of addresses and ports of customized network customers' real services and service servers, store customized network customers' real service data indicators (such as delay and rate requirements related to video surveillance services, etc.), store the wireless network status of each location of the simulation terminal, each time point, and the indicator data value of each simulation service.

[0091] The configuration sending unit is used to forward the QoS policy configuration matching the current real service to the core network.

[0092] The judgment unit is used to judge the type of the current real service through the destination IP and port of the service and to judge the QoS policy configuration matching the current real service according to the service type and the customized network customer requirements.

[0093] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
