Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. The reference numbers in the present application are only used for distinguishing the steps in the scheme, and are not used for limiting the execution sequence of the steps, and the specific execution sequence is subject to the description in the specification.
In the field of communication technology, 5G SA networks are widely used in various scenarios. For example, a live broadcast service needs to upload video signals quickly and stably through a Network, because the live broadcast service is mainly an uplink service, live broadcast Content needs to be transmitted back to a media Center of a public cloud/Internet Data Center (IDC) room for auditing and editing, and then is distributed to the public through a Content Delivery Network (CDN) Network, and the media Center relates to key logics such as auditing and service processing, generally, is difficult to sink along with Multi-access Edge Computing (MEC) in centralized deployment, so the 5G Edge Computing scheme is not suitable for a live broadcast service guarantee scene.
In addition, a guarantee scene of key services can be realized based on a slicing scheme, and the method is mainly and intensively applied to local areas such as a 5G ToB enterprise park. If the users need to be slice-guaranteed in the 5G ToB full network range, all the gsdeb base stations need to have the Resource reservation capability of Physical Resource Blocks (PRBs), and the reserved resources are only available to slice subscribers, and other users cannot occupy, which may cause the waste of wireless resources in an area with a small amount of slice subscribers. Meanwhile, the slicing scheme requires a user to replace a USIM card, and the use experience of the user is poor. However, if the slicing scheme is used in the 5G ToC network for guarantee, the terminal and the core network also need to have a UE routing Policy (URSP) capability, but at present, none of the terminal devices support Selection of corresponding network slices for different applications through the URSP rule, which results in that the 5G ToC network cannot provide quality of service guarantee for the direct broadcast and other heavy point services by using the slicing technique.
In order to solve the problems in the prior art, an embodiment of the present application provides a method for guaranteeing a 5G SA network service, as shown in fig. 1a, including:
s11: and establishing a guaranteed bit rate service quality flow corresponding to the user terminal according to the received network acceleration request, wherein the network acceleration request comprises the information of the user terminal to be accelerated.
The Network acceleration request may be actively sent by the user terminal, for example, the Network acceleration request may be actively generated by the user through an acceleration Application (APP) installed on the user terminal, and specifically, the Network acceleration request may be initiated by identifying a service flow through a Software Development Kit (SDK) and opening a Network capability (NEF). Alternatively, the network acceleration request may be generated by a device other than the user terminal according to the monitored data or the state of the device. The network acceleration request is used for applying for acceleration of the user terminal. For convenience of description, the Guaranteed Bit Rate (GBR) QoS (Quality of Service) flow is referred to as a GBR QoS flow.
S12: and acquiring IP five-tuple information of at least one network service flow of the user terminal.
The IP five tuple information may include, for example, a source IP address, a source port, a destination IP address of the server, a destination port, and a protocol.
The IP quintuple information is also referred to as quintuple information in this embodiment, or referred to as a quintuple for short, and the quintuple information may be actively obtained by the execution main body of the present solution, and specifically may obtain the quintuple information of the network service flow of the user terminal according to the information of the user terminal in the network acceleration request.
S13: updating a packet filter corresponding to the guaranteed bit rate quality of service flow, the packet filter including IP quintuple information of a target network traffic flow of the at least one network traffic flow, wherein the activity of the target network traffic flow meets a preset activity standard.
The preset liveness standard can be preset according to requirements, and can be used for screening a certain number of network service flows with high liveness when the number of the network service flows of the user terminal is excessive. And updating the packet filter according to the IP quintuple information of the target network service flow with high activity. And scheduling and transmitting the network service flow with the activity degree not meeting the preset activity degree standard through the default QoS flow.
S14: and executing message transmission of the network service of the user terminal according to the guaranteed bit rate service quality flow and the packet filter.
In the embodiment of the application, a guaranteed bit rate QoS flow corresponding to a user terminal is established according to a received network acceleration request, wherein the network acceleration request comprises information of the user terminal to be accelerated; acquiring IP five-tuple information of at least one network service flow of a user terminal; updating a packet filter corresponding to a guaranteed bit rate quality of service flow, wherein the activity of the target network traffic flow meets a preset activity standard; and executing message transmission of the network service of the user terminal according to the guaranteed bit rate service quality flow and the packet filter. The scheme screens the network service flow which is accelerated to execute based on the activity, realizes acceleration by ensuring the bit rate service quality flow, can reasonably utilize resources and effectively ensure the acceleration effect of the network core service.
The execution subject of the scheme provided by the embodiment of the present application may be an electronic device, and in this embodiment, an intelligent acceleration device is used as the execution subject for description.
The intelligent accelerating device has the following functions:
(1) The service subscription method is connected with a Business Operation Support System (BOSS) of an operator, and receives the subscription information of the accelerated Business subscription of the user.
(2) The intelligent accelerator is internally provided with a 5G network capacity opening module, and triggers QoS flow (including GBR QoS flow) creation requests of different 5G QoS indicator (5G QoS identifier, 5QI) levels to PCF network elements in a 5G network through an N5 interface (an interface between NEF and Policy Control Function (PCF)).
(3) The intelligent accelerating device collects and acquires quintuple information in the service using process of a user.
(4) The built-in NEF function module of the intelligent acceleration device needs to be docked and registered to a network storage function (NRF) network element so as to be provided with the capability of inquiring the home PCF network element of the user.
The functions of the intelligent accelerating device can be increased or reduced according to actual requirements so as to adapt to actual application scenes. In this embodiment, a system framework diagram applying the present solution may be as shown in fig. 1b, which includes devices such as a UE, a gnnodeb, a User Plane Function (UPF), a Session Management Function (SMF), and a PCF. The gNodeB, SMF, UPF and PCF are third Generation Partnership project (3 GPP) standard network elements that participate in the establishment and use of GBR QoS flows. The UE may install an acceleration application APP, so as to identify a service flow through a built-in SDK and initiate an acceleration request to the NEF. The NEF receives the application information delivered by the UE server and forwards it to the PCF. PCF receives QoS information forwarded by NEF and generates corresponding QoS flow, and informs SMF to create corresponding GBR QoS flow. The SMF issues a packet filtering rule and QoS information to the UPF, and the UPF provides functions of packet routing forwarding, policy implementation, flow reporting, qoS processing and the like, so that the SMF to the UPF to the gNodeB and finally to the UE establishes GBR QoS flow-in service message transmission to ensure the service quality.
For a guarantee scenario (e.g., a live broadcast service) with a large number of five-tuple service flows, in the scheme provided in the embodiment of the present application, an intelligent acceleration platform device may be added as an execution main body, and the device receives an acceleration request of a user, and then initiates a GBR QoS Flow creation request to a 5G SA core network, so as to set a transmission bandwidth guarantee (e.g., uplink 10 Mbps) that guarantees a Flow Bit Rate (GFBR) for the service Flow, so as to guarantee an experience Rate of the acceleration service.
Then, the intelligent accelerating device acquires and acquires quintuple message information of the terminal user. Optionally, in this step, both the source port and the destination port are set to ANY, so as to greatly reduce the number of quintuples that need to be added to the packet filter in the service use process.
Then, the intelligent accelerator identifies and counts quintuple service flows in real time, counts the access frequency and the data packet size of different quintuple service flows, screens out the most active TOP x service flow and adds the TOP x service flow into a packet filter of a GBR QoS flow, and realizes core service guarantee. Optionally, x is smaller than 16, and the specific value may be set according to the number of quintuple supported by the user terminal, for example, x =6.
In the technical field of communications, a core network may also adjust a mapping relationship between a data Flow and a QoS Flow (QoS Flow) according to a change of a QoS indicator, so as to implement differentiated QoS provisioning, and it does not relate to implementing, in a 5G SA network, a GBR QoS Flow technology to implement transmission bandwidth provisioning (e.g., uplink 10Mbps peak rate) for an end-to-end GFBR of a wireless-transport-core network for a user. When a key service (such as a live broadcast service) has the characteristic of large quantity of quintuple service flows, the quantity of Packet filters (Packet filters, one quintuple service flow is correspondingly matched with one Packet Filter) supported by a QoS Rule (QoS Rule) in a 5G SA network is not more than 16, the GBR QoS flows can be deleted after the upper limit of the number of the Packet filters is exceeded, the GFBR guarantee of the key service cannot be continuously realized, and the terminal does not support the universal configuration of defining the IP address in service flow information as all 0 to reduce the quantity of the quintuple in an actual test of the 5G SA network. Therefore, the special bearer guarantee technology cannot continuously realize the quality of service guarantee for the live broadcast service based on the establishment of the GBR QoS flow in the 5G SA network.
Specifically, under a 5G SA network, one Packet Data Unit (PDU) session supports 64 QoS flows at most, and when an end-to-end service guarantee needs to be implemented by creating a proprietary bearer, a new GBR QoS flow is created in a PDU session modification flow. The 3gpp TS 24.501 protocol specifies that the length of a packet filter in a QoS rule of 1 QoS stream is 4 bits, that is, 16 packet filters are supported at most. In the practical application of the 5G network, the maximum support number of the packet filter associated with the PDU session is realized based on the terminal, and the protocol is not defined explicitly. Under the SA network shown in fig. 1c, a test is performed according to a Policy Control and Charging (PCC) Policy of static subscription of a subscriber number, for example, subscription 5QI is guaranteed for a GBR QoS flow of 4, when it is found that a terminal has a data flow, a UPF inserts packet filters into the created GBR QoS flow according to a quintuple of the data flow, when a certain GBR QoS flow is inserted into an M (M is less than or equal to 16, a specific value is defined by the terminal, for example, the M value of Mate 30 terminal is 8), the terminal returns a #26 instant resource error failure code, which causes the SMF and the UPF network element to delete the GBR QoS flow, a service data flow triggers creation of a new GBR QoS flow, and the above process N is repeated (when total QoS flows are not more than 64, a specific value is determined by the terminal and the network side), and then a new GBR flow is triggered, and all service default QoS flows are no longer supported by the QoS flow. The schematic diagram of the quintuple in the GBR QoS flow and the flow chart of the GBR QoS flow creation in the scenario of a large number of quintuples are shown in fig. 1d and fig. 1e, respectively.
In the process of using a service by a User, although a source IP address of a User Equipment (UE) is fixed and unchanged and a protocol (such as TCP or UDP) applied to the service is fixed, a source port changes with a change of a content in the process of using the service, and a destination IP address and a port of a service server also change with an update of the content of the service. For example, when live traffic testing is performed in a scenario with UE background traffic, statistics show that the number of quintuples in an hour can be as high as thousands. In summary, in the 5G SA network, the method of using the PCC policy statically signed according to the user number as shown in fig. 1c cannot continuously guarantee the GBR QoS flow with a large number of quintuple services.
The 3GPP specification does not specify the quintuple rule of the Packet Filter, the terminal supports the quintuple having the detailed source IP address, the destination IP address and the protocol, and it is found during actual test that the terminal reports an error when the detailed source IP address and the destination IP address are not specified. For example, if the IP address sent by the core network to the terminal contains 0.0.0.0, the terminal will reply with a #84 syntax error in the QoS operation failure code. Therefore, in the 5G SA network, for services with unknown IP addresses, it is impossible to reduce the number of quintuples by defining the IP addresses in the service flow information as all 0 and other common configurations on the core network side, thereby realizing continuous guarantee based on GBR QoS flows.
In the solution provided in the embodiment of the present application, at least one network service flow of a user terminal is screened according to a preset liveness standard, and a packet filter is updated according to IP quintuple information of a target network service flow that meets the preset liveness standard, so as to implement service guarantee for the active target network service flows, and avoid a situation that the amount of IP quintuple information data to be added to the packet filter is too large. And then, network service resources can be fully utilized to guarantee core services, and meanwhile, overhigh load is avoided, and important and active service guarantee is realized.
Based on the solution provided in the foregoing embodiment, optionally, the preset liveness criterion includes that the access frequency of the network service flow is greater than a preset access frequency and/or the size of a data packet transmitted by the network service flow exceeds a preset threshold.
In the embodiment, the network traffic flow is screened according to the access frequency and/or the size of the transmitted data packet of the network traffic flow, which is the target network traffic flow. The screened active target network traffic flow is often network traffic that is being used or frequently used by the user. The target network service flow obtained by screening is accelerated, so that the use experience of the user network service can be effectively ensured, the speed is improved, and the stability of the network service is ensured.
Based on the solution provided in the foregoing embodiment, optionally, the number of IP five tuple information included in the packet filter is not greater than a first preset number, where the first preset number is determined according to the user terminal. In this embodiment, the first preset number is represented by M.
The quintuple numbers supported by different terminals are different, namely the numbers in the packet filters corresponding to the GBR QoS flows are different, and the value of the quintuple number set by the scheme is generally not greater than the minimum quintuple number supported by the terminal.
Based on the solution provided by the foregoing embodiment, optionally, as shown in fig. 2a, step S11 includes:
s21: when the number of the guaranteed bit rate QoS flows corresponding to the user terminal is smaller than a second preset number, establishing guaranteed bit rate QoS flows corresponding to the user terminal according to the received network acceleration request;
wherein, before S11, further comprising:
s22: and when the number of the guaranteed bit rate service quality flows corresponding to the user terminal is greater than or equal to the second preset number, executing message transmission of the network service of the user terminal according to the preset service quality flows.
In this embodiment, the second predetermined number is represented by N.
In practical application, a user terminal has background service flows in the actual service use process and the IP addresses of most service servers are more, the method identifies and counts quintuple service flows in real time based on an intelligent accelerating device, then counts the access frequency and the data packet size of all quintuple service flows, and adds the IP quintuple of x service flows less than the upper limit M of a packet filter to the packet filter so as to ensure the active network services. According to the scheme, the operation of deleting is not required to be executed when the number of GBR QoS flows is excessive, and the transmission of the message of the network service is determined according to the parameters of the GBR QoS flows after the network acceleration request is received, so that the communication quality of the active network service is guaranteed through the GBR QoS, the message of the relatively inactive network service is transmitted through the default service quality flow, the reasonable distribution of network resources is realized, and the core network service of the user terminal is guaranteed.
In the following, the present solution is further explained by combining with an example, and fig. 2b shows a flowchart for implementing continuous service provisioning with a large number of quintuple service flow scenarios based on GBR QoS flows. Which comprises the following steps:
s202: after a user registers in a 5G SA network, firstly establishing a default QoS flow when using a service;
s204: and the core network side judges whether the number of times of creating the new GBR QoS flow is more than N.
(on the premise that the total QoS flows do not exceed 64, the specific value is determined by the terminal and the network side, for example, the terminal finds N =5 in a 5G SA network): if the value is less than or equal to N, go to step S206; if the value is larger than N, the step S208 is executed;
s206: creating a new GBR QoS flow, and a corresponding QoS rule and a packet filter set thereof;
s208: no new GBR QoS flow is created, namely the GBR QoS flow transmission can not be utilized to ensure the service quality, and all the service flows are forwarded and processed by using default QoS flows;
s210: five tuples of active TOP x (x < M, M is the upper limit number of the packet filter) in the statistical period (such as 30 seconds, 1 minute, 2 minutes and the like) are added into the packet filter set.
S212: is it determined whether the cycle of retiming the statistically active TOP x quintuple has been reached? If not, go to step S216; if the period of re-counting has been reached, go to step S214;
s214: counting up the latest active TOP x quintuple again, updating and replacing the latest active TOP x quintuple into a packet filter set, and ensuring that the number of IP quintuple in the packet filter set of the flow rule is always smaller than the upper limit number of the IP quintuple;
s216: different service flows map their data messages to different QoS flows according to the corresponding QoS parameters, and these QoS flows with different QoS parameters can be identified at the access network side, and then can be respectively given different processing and forwarding strategies, so that the data therein reaches the specified QoS level.
Based on the solution provided by the foregoing embodiment, optionally, after the foregoing step S13, as shown in fig. 3, the method further includes:
s31: periodically acquiring IP five-tuple information of at least one network service flow of the user terminal;
s32: and updating the packet filter according to the IP quintuple information of the network service flow which is periodically acquired and meets the preset activeness standard.
In this embodiment, active traffic flows are counted periodically, for example, the period may be 30 seconds, 1 minute, 2 minutes, and the like, so as to dynamically update and count TOP x active traffic flows, thereby achieving an effect of continuously guaranteeing, in real time, a service to be accelerated for a user.
Based on the solution provided by the foregoing embodiment, optionally, as shown in fig. 4, after the foregoing step S31, the method further includes:
s41: and when the preset information in the IP quintuple information of the network service flow which is periodically acquired and meets the preset liveness standard is the same as the preset information in the packet filter, not updating the packet filter, wherein the preset information comprises a source IP address, a destination IP address of the server and a protocol.
In this step, both the source port of the user terminal and the destination port of the service server are set to ANY, that is, when the source port or the destination port is randomly changed in the range of 0 to 65535, for the same user terminal (the source IP remains fixed) and the same application (the protocol type is such as TCP or UDP remains unchanged), if the destination IP address is unchanged, the IP quintuple corresponding to the service flow remains unchanged, thereby greatly reducing the number of IP quintuples required to be added to the packet filter in the service use process. The destination IP address of the server in this step is the destination IP address described in the above embodiment.
