[0023] Embodiment one
[0024] Figure 1 A flowchart of a data distribution method without Internet access provided by an embodiment of the present application, the embodiment can be applicable to the case of data distribution without Internet access after an emergency event, and the method can be executed by a data distribution device without Internet access, which can be realized in the form of hardware and / or software, and can be configured in any electronic device with network communication function. As shown in the figure, the data distribution method without Internet access of the present application can include: Figure 1 As shown in the figure, the data distribution method without Internet access of the present application can include:
[0025] S110, in response to the data request issued by the target object to the UPF, determining the subscription state of the target object; the subscription state is used to describe whether the data distribution function is signed between the target object and the UPF.
[0026] In the 5G core network, the UPF (User Plane Function, user plane function) is the "data forwarding hub" of the core network, which is specially responsible for the routing, forwarding, shunting and statistics of user data (such as web page data, video stream, Internet of Things device data), is the core user plane network element of the control plane and user plane separation architecture, and directly determines the delay, bandwidth and reliability of data transmission.
[0027] Currently, the reference object and the target object belong to the same 5G core network field, and the process of the reference object transmitting data to the target object is usually that the reference object issues reference data, the reference data is first transmitted to the base station corresponding to the reference object, the base station corresponding to the reference object is then transmitted to the UPF corresponding to the reference object, the UPF corresponding to the reference object transmits the reference data to the UPF corresponding to the target object through an application server, the UPF corresponding to the target object transmits the reference data to the base station corresponding to the target object, and the base station corresponding to the target object then transmits the reference data to the use equipment of the target object. Among them, the application server is the public Internet, and is not the same 5G core network field as the reference object and the target object. When an emergency event occurs, the network will be interrupted, so that the data cannot be transmitted to the application server, and the data cannot be issued to the target object. However, the application can realize the issuance of the data content corresponding to the data request to the target object through the UPF in the state of no network by signing the data issuance function between the target object and the UPF.
[0028] Optionally, the data distribution method without Internet access further includes: obtaining the identity information of the subscription object, generating the PCC rule by the PCF according to the identity information, and issuing the PCC rule to the SMF through the N15 interface, so as to accurately determine the data issuance function between the subscription object and the UPF. Among them, the PCF (policy control function) and the SMF (session management function) are the key interaction objects of the UPF.
[0029] Further, determining the subscription state of the target object can include: obtaining target identity information of the target object, and determining the subscription state of the target object based on the target identity information and the PCC rule. Among them, the target identity information can be saved in the data request. The PCC rule saves the subscription identification information between the identity information and the UPF. Therefore, when the target identity information can be matched with the PCC rule subscription identification information successfully, it is determined that the subscription state of the target object is subscribed, otherwise the subscription state is unsubscribed.
[0030] Optionally, in response to the data request issued by the target object to the UPF, it is necessary to ensure that the session connection between the target object and the UPF is established, and the data issuance is ensured, so the method further includes: in response to the data request issued by the target object to the UPF, it is determined that the target object initiates a session establishment request, that is, in response to the session establishment request initiated by the target object, the SMF triggers the session between the target object and the UPF. Specifically, after the target object initiates the session establishment request, the AMF forwards the session establishment request to the SMF, triggers the SMF to establish the session between the target object and the UPF, and connects the communication between the target object and the UPF.
[0031] S120. If the contract status is "signed", then send the data content corresponding to the data request to the target object.
[0032] The target object and the UPF belong to the same 5G core network domain; the UPF adds a local storage module for storing multimedia resources. This invention can use the Hypertext Transfer Protocol (HTTP) for data distribution.
[0033] Specifically, the data content is stored in the newly added local storage module of the UPF. Data can be transferred from the local hard drive to the UPF's local storage module. When the subscription status is confirmed as "subscribed," the data content corresponding to the data request is retrieved from the UPF's local storage module and then distributed to the target object. The data content distributed by the UPF is diverse, dynamically selecting the content to be distributed based on region, target group, time, subscription status, etc. Furthermore, directly obtaining data content from the core network UPF side results in low latency, high bandwidth, and reduced congestion, improving user experience.
[0034] Optionally, the data request includes a Uniform Resource Locator (URL), which includes the target domain name and the target path. The target domain name can be understood as the network address of the server where the resource is located, and can be resolved to the server's IP address through DNS (Domain Name System). The target path can be understood as the specific storage location of the resource on the server, equivalent to a "file path" on the server, indicating which file in which folder is being accessed.
[0035] Accordingly, sending the data content corresponding to the data request to the target object may include: resolving the target domain name through a DNS server to obtain the resolution result; the resolution result includes the address information for storing the data content corresponding to the data request; based on the resolution result, determining the target local storage module from the UPF's local storage module; based on the target path, retrieving the data content corresponding to the data request from the target local storage module, and sending the data content corresponding to the data request to the target object.
[0036] Furthermore, after the target object receives the data content corresponding to the data request, the target object's operating system will display the data content corresponding to the data request on its display page. The operating system can be a mobile device.
[0037] The technical scheme of the embodiment of the present application determines the subscription state of the target object in response to a data request issued by the target object to the UPF; the subscription state is used to describe whether the target object has signed a data distribution function with the UPF; if the subscription state is signed, the data content corresponding to the data request is distributed to the target object, so that the continuous, controllable and high-quality multimedia content distribution service can be provided in the case that the public network is unavailable, and the resilience and public service capability of the mobile network in the extreme environment are significantly improved. The data distribution process of the present application completely depends on the 5G core network, and completely gets rid of the dependence on the public Internet source, and the stable service can still be provided in the stress scenarios such as network interruption, network attack or natural disaster.
