[0040] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] The present invention aims to solve the problem of poor transmission stability and security caused by using ordinary networks in the prior art. By slicing the hospital wireless, transmission and core network, an end-to-end slicing solution is implemented. Combined with edge computing, the stability and security of medical video stream transmission can be effectively improved. The present invention will be described and introduced in detail through multiple embodiments in conjunction with the accompanying drawings.

[0042] like Figure 1 As shown, it is a structural schematic diagram of the 5G basic network architecture applied to the 5G network slicing implementation method for medical scenarios provided by the present invention, wherein: UE represents user terminal equipment (User Equipment), that is, the medical equipment terminal in the present invention, which is a device that generates medical videos, such as ultrasound imaging instruments, case slice data equipment, etc.; (R)AN represents a 5G base station; AUSF represents the authentication service function (Authentication Server Function) of the 5G network; AMF represents the access and mobility management function; SMF represents the session management function; UPF represents the user plane function (The User plane Function); PCF represents the policy control function (Policy Control Functiong); UDM represents the unified data management (The Unified Data Management); NRF represents the network registration function (NF Repository Function); NSSF represents the network slice selection function (The Network Slice Selection Function), NEF represents the network exposure function (Network Exposure Function); DN represents the network to be accessed by the service.

[0043] In the existing business process, the terminal belonging to the 5G network will initiate a registration request to the 5G core network through RAN. RAN will send the request to AMF, and the AMF, AUSF, UDM and other network elements will authenticate the user. After successful authentication, SMF will allocate a suitable UPF to the user for the transmission of user-plane services (business traffic, such as WeChat voice transmission, web traffic, video, etc.). The device through which the service is transmitted is UE-RAN-UPF-DN, where UE-RAN adopts wireless transmission technology and RAN-UPF transmits through the Slicing Packet Network (SPN) (similar to a router) network.

[0044] The present invention aims at the pain point of high-traffic video transmission scenarios in hospitals, such as surgical guidance, pathological slice transmission, and overtime real-time imaging, which have higher requirements for network stability, low latency, large bandwidth, and data security. By combining technologies such as 5G slicing, edge computing, and PCC strategy, the present invention designs end-to-end 5G technical solutions from the aspects of wireless, transmission, and core network, realizes slicing of 5G networks, and thus achieves stable, fast, and secure transmission of high-traffic video streams in medical scenarios.

[0045] Among them, network slicing is an important enabling technology for 5G networks, which can meet the specific needs of different business types, business scenarios and vertical industries. Network slicing is an end-to-end logical subnet, involving the core network (control plane and user plane), wireless access network, Internet Protocol (IP) bearer network and transmission network, which requires the coordination and cooperation of multiple fields. Different network slices can share resources or be isolated from each other.

[0046] The core network control plane of network slicing is deployed using a service-oriented architecture. The user plane uses a combination of software forwarding acceleration, hardware acceleration and other technologies to achieve a balance between user plane deployment flexibility and processing performance based on the business requirements for forwarding performance. While ensuring that key indicators such as spectrum efficiency, system capacity, and network quality are not affected, wireless network slicing focuses on the utilization efficiency of air interface time and frequency resources, and uses a combination of flexible frame structures, QoS differentiation and other technologies to achieve intelligent scheduling of wireless resources, and through flexible wireless network parameter reconfiguration functions, it realizes differentiated slicing functions.

[0047] Figure 2 A flow chart of a method for implementing 5G network slicing for medical scenarios provided by the present invention is shown in FIG. Figure 2 As shown, the method includes:

[0048] S201, connect the medical equipment terminal to the 5G base station in the hospital area to realize wireless side networking, and perform wireless side network slicing processing and wireless resource reservation settings by configuring wireless side network parameters.

[0049] Among them, the wireless side network parameters include a first SST parameter, and the first SST parameter is an SST parameter of a dedicated section.

[0050] It can be understood that the present invention is implemented from three aspects of the end-to-end wireless, transmission, and core network of the 5G network. By designing the technical parameters of these three network segments, a technical implementation plan for the entire slicing network from wireless, transmission to the core network is realized, which can ultimately solve the problems of stable, fast, and secure video transmission in medical scenarios.

[0051] Specifically, for the wireless side network, network slicing and parameter configuration are performed to implement slicing processing. Figure 3 As shown, it is a schematic diagram of slice network networking in the 5G network slicing implementation method for medical scenarios provided by the present invention, wherein in the wireless access solution, the wireless side networking is realized by adopting a method in which the medical device terminal accesses the access device of the 5G base station.

[0052] Optionally, connecting the medical device terminal to the 5G base station in the hospital area includes: if the medical device terminal is not configured with a 5G module, connecting the medical device terminal to the access device of the 5G base station through a 5G gateway; if the medical device terminal is configured with a 5G module, directly connecting the medical device terminal to the access device of the 5G base station.

[0053] It can be understood that in the wireless access solution, access can be considered through 5G CPE + video equipment (no 5G module) + 5G base station or video equipment (5G module) + 5G base station. In other words, if the hospital video streaming device does not have a 5G module, the video streaming device that the hospital needs to upload can be accessed through the 5G gateway (CPE). If the hospital video streaming device has a 5G module, it can be directly accessed to the 5G base station. The access is achieved by connecting the 5G module to the access device of the 5G module. The 5G CPE or 5G module can be inserted into the 5G ToB hospital private network card that has been opened in the 5G core network.

[0054] For wireless side parameter configuration, the present invention configures wireless network parameters for hospitals based on 5G slicing technology, combined with the hospital's own scenarios and 3GPP specifications, including planning a new slice ID, i.e., the first SST parameter (SST>128), and based on the slice ID, provides consistent SST parameters for wireless, transmission and core networks. Through slicing and wireless RB reservation (wireless resource reservation), wireless side resources can be guaranteed.

[0055] S202, build a mobile edge computing MEC server, and connect the mobile edge computing MEC server to the 5G core network to realize core network side networking, and perform core network side network slicing processing by configuring core network side network parameters.

[0056] Among them, the core network side network parameters include a second SST parameter, and the second SST parameter is consistent with the first SST parameter.

[0057] It can be understood that the present invention builds new MEC (UPF+server) local campus equipment on the core network side to ensure that the hospital video traffic does not leave the campus, thereby ensuring the security of the hospital traffic. At the same time, in order to use the existing 5G network equipment, the newly built MEC is connected to the existing 5G network core network equipment, such as AMF, SMF and other equipment, to achieve core side networking. On the basis of realizing network slicing networking, parameter configuration is performed on the core network side, involving parameter configuration for core network devices such as AMF, SMF, PCF, etc., including the slice (SST) parameters opened on AMF and SMF, that is, the second SST parameters, and the second SST parameters are consistent with the first SST parameters configured in the wireless network.

[0058] S203 connects the 5G base station to the mobile edge computing MEC server through an aggregation device, and performs transmission side network slicing processing by configuring transmission side network parameters and activating the FlexE function of the 5G base station and the mobile edge computing MEC server.

[0059] Among them, the transmission side network parameters include a third SST parameter, and the third SST parameter is consistent with the first SST parameter.

[0060] It can be understood that based on the networking of the wireless side and the core network side, the transmission side networking can be carried out, such as Figure 3 As shown in the figure, the transmission side networking focuses on the transmission network from the base station access device to the MEC. Under normal circumstances, this transmission network transmits all traffic services of the operators in the region (including ToC and ToB). Specifically, the medical device terminal is accessed through the access device of the 5G base station, and the newly built MEC server is accessed through the aggregation device of the 5G base station.

[0061] On the basis of networking, FlexE technology can be enabled. Specifically, the FlexE function can be enabled in the transmission access equipment, aggregation equipment of 5G base stations, and transmission access equipment of MEC to achieve transmission slicing and ensure that the hospital video stream is not limited by the transmission bandwidth.

[0062] The 5G network slicing implementation method for medical scenarios provided by the present invention implements an end-to-end slicing solution by performing network slicing processing on the hospital's wireless, transmission and core network sides respectively. Combined with edge computing, it can effectively improve the stability and security of medical video stream transmission.

[0063] Among them, the 5G network slicing implementation method for medical scenarios provided according to the above embodiments is optional, and the method also includes: for the ToB SIM card of the hospital's exclusive user 5G, a dedicated number segment is configured for it to access the operator's ToB private network.

[0064] It can be understood that the present invention configures the number segment for the 5G ToB SIM card of the hospital's exclusive user to access the operator's ToB private network. Through configuration, the hospital can exclusively enjoy DNN and exclusive slices with SST greater than 128, and the DNN and slices are exclusive to the hospital's video traffic services.

[0065] Among them, according to the 5G network slicing implementation method for medical scenarios provided in the above embodiments, the configuring of wireless side network parameters includes:

[0066] Confirm the number of the 5G base station covering the hospital;

[0070] Confirm the 5G base station ID covering the hospital;

[0071] Planning or reusing existing TACs and communities for hospitals;

[0072] Configure the RB reservation configuration for the hospital video card and the cell base station.

[0073] After the configuration is completed, when the hospital video card completes the registration in the 5G private network, the wireless resources where the video device is located can be effectively guaranteed. Even if the wireless network is congested due to crowded hospital staff, the transmission of the video stream will not be affected in any way.

[0074] Among them, according to the 5G network slicing implementation method for medical scenarios provided in the above embodiments, the configuring of core network side network parameters includes:

[0075] Opening the SST parameters under the second SST parameter network segment on the access and mobility management function AMF and the session management function SMF to support access of medical video slices;

[0076] Configuring a relationship with the mobile edge computing MEC server in a session management function SMF;

[0077] Configuring an uplink offload function in the mobile edge computing MEC server;

[0078] The computing resources are enabled in the mobile edge computing MEC server.

[0079] It can be understood that the core network side parameter configuration will involve core network devices such as AMF, SMF, PCF, etc. The core network side configuration scheme and parameters are as follows:

[0080] The slice (SST) parameters under this network segment are enabled on AMF and SMF to support the access of medical video slices.

[0081] Configure the relationship with MEC in SMF. When a medical video user is in TAC, the user needs to be directed to MEC.

[0082] The uplink traffic diversion function is configured in MEC. Sensitive data streams such as patient pathological sections and timed real-time images are transmitted to the local server in the hospital. For data that can be transmitted to the public network, the public network node IP is configured to achieve local data offload.

[0083] Computing resources are activated in MEC and used to process medical imaging data to realize edge computing functions.

[0084] Among them, according to the 5G network slicing implementation method for medical scenarios provided in the above embodiments, the configuration of the transmission side network parameters and the activation of the FlexE function of the 5G base station and the mobile edge computing MEC server include:

[0085] Confirming that the third SST parameter is consistent with the first SST parameter on the wireless side and the second SST parameter on the core network side;

[0086] The FlexE function is enabled in the transmission access device of the 5G base station, the aggregation device of the 5G base station, and the transmission access device of the mobile edge computing MEC server.

[0087] It can be understood that in order to protect the resources in the transmission network, the transmission side configuration scheme and parameters are as follows:

[0088] Confirm that the SST allocated on the wireless side and the core network side is consistent;

[0089] Enable the FlexE function in the transmission access equipment, aggregation equipment of the base station, and the transmission access equipment of the MEC. For example, enable the bandwidth of 1GE-10GE as needed.

[0090] The present invention uses slicing and edge computing to transmit medical images and pathological slices, solving the current problems of unstable and unsafe medical video stream transmission.

[0091] Based on the same inventive concept, the present invention also provides a 5G network slicing implementation device for medical scenarios according to the above-mentioned method embodiments, and the device is used to complete the implementation of 5G network slicing for medical scenarios in the above-mentioned method embodiments.
