Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
It should be noted that although functional block divisions are provided in the system drawings and logical orders are shown in the flowcharts, in some cases, the steps shown and described may be performed in different orders than the block divisions in the systems or in the flowcharts. The terms first, second and the like in the description and in the claims, and the drawings described above, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
The embodiments of the present application will be further explained with reference to the drawings.
Referring to fig. 1, fig. 1 is a schematic diagram of a service providing system provided in an embodiment of the present application, where the system includes a source NF (Network Function) 110, an NRF (Network Repository Function) 120, and a target NF 130. When the NF needs to dynamically access its respective service, the source NF that needs to request the service makes a request to the NRF. In the 5G core network, the NRF is used to provide network function discovery services for other network elements, so the NRF searches for a suitable target NF according to the request of the source NF, and returns information such as the address of the target NF to the source NF in a NF discovery response manner, so that the source NF can request corresponding services from the target NF according to the address. And after receiving the request, the target NF provides service to the source NF to complete the service providing process in the 5G core network.
In the related art, NRF can only realize NF discovery at a network element level, that is, when NRF finds a target NF, service ports in the target NF are randomly allocated to a source NF for use, which may cause data congestion of some ports in the target NF and idle of other ports, thereby causing waste of network resources and affecting service processing efficiency of a core network.
Therefore, an embodiment of the present invention provides a service providing method, which enables an NRF to discover a port level, and the service providing method provided in the embodiment of the present invention is described below with reference to fig. 1.
First, the 29510 protocol of TS 3GPP proposes: and the NF uses a plurality of addresses and ports when NRF is registered, and message data between network elements are transmitted in parallel. However, addresses and ports in the NF are not specifically distinguished in the related art, so the NRF randomly allocates service ports of the NF when performing service discovery. The procedure of the NF creating a plurality of service ports in the service providing method according to the embodiment of the present application is described below.
Referring to fig. 2, fig. 2 is a flowchart illustrating steps of the NF creating a service port according to an embodiment of the present application, and the method steps illustrated in fig. 2 may be applied to the source NF or the target NF in fig. 1, and the method includes, but is not limited to, steps S200 to S230:
s200, after starting, establishing an initial service port;
specifically, in the process of providing the service according to the embodiment of the present application, after the NF is started, the NF may configure and establish an initial service port according to actual needs, and establish a corresponding information monitoring flow to provide the service for the initial service port. It is understood that the initial service port refers to a service port that the NF must have when the core network provides or requests a service.
S210, sending a registration request to an NRF, wherein the registration request comprises network element information and port information corresponding to an initial service port;
specifically, when the initial service port and the corresponding information monitoring process are configured, the NF sends a registration request to the NRF, where the registration request includes the network element information and the port information corresponding to the initial service port. When the NF completes registration on the NRF and receives a registration completion response of the NRF, the current NF is ready to provide services to or request services from other NFs.
S220, monitoring the initial service port, and creating a new service port according to the network resource condition and the congestion condition of the initial service port;
specifically, in the process of providing the service, the NF may periodically check the initial service interface through the information monitoring flow, and determine the congestion condition of the related process processing message and the processing condition of the main service. When the number of messages to be processed in the network increases and the traffic volume decreases, some service ports may become congested ports, and the monitoring process corresponding to the congested port is congested or the corresponding load is too heavy. When finding that the congestion port exists in the initial service interface, checking the current network resource condition, if the current network resource still has redundant network resources, the NF can create another new service port which is the same as the congestion port, and when other NF needs the service port of the type to provide service again, the NF can allocate the new service port to provide service for other NF, thereby fully utilizing the vacant network resources, effectively reducing the load pressure of the original congested port and reducing the network congestion condition. And when multiple service ports of the same type exist in the NF, the data concurrency function can be realized, and the network communication efficiency is effectively improved.
It can be understood that, according to the congestion condition of the initial service port of the NF and the port type where the network congestion occurs, in the embodiment of the present application, the NF may determine how many new service ports need to be created, and may also determine what types of new service ports respectively belong to and what services can be provided.
In some embodiments, the port information of a service port includes, but is not limited to, one or more of public land mobile network identification, slice identification, supported network element type, service type identification, and the like, and in this application, the port information also includes a priority and a current load of the port. According to the above, when the NF monitors the service port, it can be determined whether a new port of the same type needs to be created to relieve the load pressure through the current load of the service port, and after the new port is created, the ports can be prioritized, for example, the priority can be determined according to the load condition, the priority of the port with light load is high, and the priority of the port with heavy load is low, so that the NRF can reasonably allocate the port resources, thereby avoiding the waste of network resources.
In other embodiments, in addition to the information of the public land mobile network identifier, the slice identifier, the supported network element types, the service type identifier, the priority, the current load, and the like mentioned in the above embodiments, the embodiment of the present application further adds an identifier of a supported user type in the port information, where the identifier of the user type is mainly used to create a dedicated service port for some types of users, so as to ensure the communication quality of the type of users. In this embodiment, when the source NF is specifically an Access and Mobility Management Function (AMF), the AMF may send a subscription Data request to a Universal Data Management (UDM) in response to a terminal registration request sent by the terminal, where the request is used to obtain subscription Data related to a user corresponding to the terminal, and the subscription Data includes a user type, and then, after receiving the subscription Data returned by the UDM, the AMF may create a dedicated service port corresponding to a user of a current type according to the user type. Subsequently, when the user of the type needs the NRF to discover the services of other network elements, such as session establishment service and location service, the NRF can allocate a dedicated service port to the user according to the user type in the port information for service, thereby effectively ensuring that the communication resource of the user of the type is not occupied by other users and improving the communication quality of the user using the dedicated service port.
According to the embodiments, the service providing method provided by the embodiments of the present application can create a plurality of new service ports of different types according to the network resource situation and the congestion situation of the initial service port, so as to improve the communication efficiency of the network in a data concurrent manner. It can be understood that the new service port also establishes a corresponding monitoring process, that is, the NF can monitor all current service ports at regular time. Therefore, when the overall network resources are in a shortage, the previously created service ports can be released, for example, according to the monitoring conditions of all the service ports, the idle service ports in the type a are released, and then the spare network resources are used for creating new service ports of the type B, so that the effects of reasonably distributing and fully utilizing the network resources are achieved.
S230, sending heartbeat information to the NRF, wherein the heartbeat information comprises port information of all service ports;
specifically, with the above contents, the embodiment of the present application provides a process of creating or releasing a service port according to a network resource condition and a monitored congestion condition of the service port, so that in a process of creating or releasing the service port, an NF may periodically send heartbeat information to an NRF, where the heartbeat information includes port information of all service ports in the current NF, that is, a port condition on the NF may be periodically updated to the NRF through the heartbeat information, and when the NRF needs to allocate a service port of the NF, reasonable allocation may be performed according to a latest port condition of the NF.
Through steps S200-S230, the embodiment of the present application provides a method for the NF to create or release a service port according to network resources and the conditions of its own port, except for fixing a service interface to be used, when a network element of the same program is installed on hosts with different resource environments, its own service port can be dynamically adjusted according to the conditions of the host resources, so as to achieve the purpose of fully utilizing the network element resources.
Through the above content, the present application embodiment provides a method for an NF to create multiple service ports and implement data concurrency, where after the NF creates a port and synchronizes port information to an NRF, the NF may access other NFs to obtain services. Referring to fig. 3, fig. 3 is a flowchart illustrating a first step of a service providing method according to an embodiment of the present application, where the method steps corresponding to fig. 3 are applied to a source NF in the system shown in fig. 1, and the method includes, but is not limited to, steps S300-S320:
s300, sending a discovery request to an NRF; the discovery request comprises a network element matching condition and a port matching condition;
specifically, a source refers to a source, a source NF in the embodiment of the present application refers to an NF that needs to initiate a service request to another NF network element in a current communication service flow, and correspondingly, an NF that provides a service in the current communication flow is referred to as a target NF. It should be noted that the source NF and the target NF are only two NFs for distinguishing the requested service from the provided service in the current communication flow, and are not used to indicate a specific NF.
In this step, the source NF sends a discovery request to the NRF, where the discovery request includes a preset network element matching condition and a preset port matching condition according to the specific needs of the current communication service flow, and the two conditions are used for the NRF to determine the target NF and the target service port.
S310, receiving a network element address of a target NF and port information of a service port returned by the NRF;
specifically, the source NF receives the network element address of the target NF and the port information of the service port returned by the NRF.
S320, requesting service from the target NF according to the network element address and the port information, and receiving the service provided by the target NF;
specifically, the source NF requests a service from the target NF according to the received network element address and port information, and the target NF provides the service to the source NF, thereby completing the service providing process.
Through steps S300-S320, the process from the source NF to the corresponding service is described in the embodiment of the present application, and the process from the NRF to receive the service request and complete the NF service port assignment is described below.
Referring to fig. 4, fig. 4 is a flowchart illustrating a second step of a service providing method according to an embodiment of the present application, and the method steps corresponding to fig. 4 are applied to the NRF in the system shown in fig. 1, where the method includes, but is not limited to, steps S400-S430:
s400, receiving a discovery request sent by a source NF; the discovery request comprises network element matching conditions and port matching conditions;
specifically, the NRF receives a discovery request sent by a source NF, where the discovery request includes a network element matching condition and a port matching condition, the network element matching condition is used to select a target NF that is suitable for the condition, and the port matching condition is used to select a target service port that is suitable for the condition from ports of the target NF.
S410, determining a target NF according to the stored network element information and the network element matching condition;
specifically, it is mentioned in the above that, when the NF registers on the NRF, the NF sends a registration request including the network element information and the port information to the NRF, and after receiving the registration request sent by the NF, the NRF parses the registration request and stores the network element information and the port information obtained by parsing. After the NF is registered, the NRF also continuously receives heartbeat information sent by the NF, and the heartbeat information includes new port information, so that the NRF can update the stored old port information according to the new port information.
Therefore, in this step, since the NRF stores the network element information sent when the NF is registered or the heartbeat information is sent, the NRF can realize the discovery of the network element level according to the stored network element information, that is, the NRF determines the target NF according to the stored network element information and the network element matching condition.
It should be noted that, in this step, the target NF may be specifically determined by using a method for implementing network element level discovery in the related art, and since implementing network element level discovery does not belong to the improvement of the embodiment of the present application, details are not described herein.
S420, determining a target service port in the target NF according to the stored port information and the port matching condition;
specifically, the NRF stores port information sent when the NF registers or sends heartbeat information, and according to the stored port information, the NRF in the embodiment of the present application can discover a port level, that is, determine a target service port according to the stored port information and a port matching condition.
It will be appreciated that the above mention is made in the 29510 protocol of TS 4 GPP: and the NF uses a plurality of addresses and ports when NRF is registered, and message data between network elements are transmitted in parallel. Therefore, under the condition that the target NF has a plurality of service ports, the service ports are not randomly allocated by the NRF any more in the embodiment of the present application, but the NRF determines the specific service port according to the port information and the port matching condition, so that the reasonable allocation of the NF port resources is realized, the network congestion and the resource waste caused by the random allocation of the service ports by the NRF are effectively solved, and the service processing efficiency of the core network is improved.
In the above, the port information includes various information related to the service port, and taking the port information including the service type identifier, the current load, and the priority as an example, in this step, determining the target service port in the target NF according to the stored port information and the port matching condition specifically includes: firstly, according to port matching conditions, screening service types in port information stored in an NRF, determining one or more service ports in a target NF, which are consistent with the port matching conditions, and if only one determined service port is provided, the NRF selects the service port to provide services for a source NF. If there are multiple service ports determined according to the service types, an optimal service port can be determined from the multiple service ports as a target service port according to the current loads and priorities of the ports, so as to provide services for the source NF. The optimal service port can be obtained by screening according to the conditions that the current load is lightest, or the priority is highest, and the like.
As mentioned above, the port information further includes an identifier of a user type, and the NF creates a dedicated service port for some users according to the user type identifier to ensure the communication quality of the users, so in this step, first, the dedicated service port in the target NF is determined according to the user type in the port information; and then determining a target service port from the plurality of special service ports according to the current load and priority corresponding to the special service port, and providing service for the source NF by the target service port.
S430, sending the network element information of the target NF and the port information of the target service port to the source NF;
specifically, after determining the target NF and the target port for providing the service in the target NF according to step S420, the NRF sends the network element information of the target NF and the port information of the target service port to the source NF, so that the source NF can determine the target NF address to be accessed according to the network element information, determine the specific service port for providing the service in the target NF according to the port information, and provide the service by the target NF, thereby completing the process of the service providing method in the embodiment of the present application.
Through steps S400-S430, the embodiment of the present application explains a process of receiving, by an NRF, a service request sent by an NF and completing NF service port assignment, from the perspective of the NRF.
In summary, an embodiment of the present application provides a service providing method, including: the NF dynamically adjusts the number and the type of the service ports according to the monitoring condition of the service ports and the network resource condition of the NF, synchronizes the port information to the NRF along with the registration request or the heartbeat information, and stores and updates the corresponding port information by the NRF. And when the source NF needs to access the service of other NF, sending a discovery request to the NRF, wherein the discovery request comprises a network element matching condition and a port matching condition. And after receiving the discovery request, the NRF determines one or more target NF (networks) meeting the conditions according to the stored network element information and the network element matching conditions. Then, the NRF determines a target service port in the target NF according to the stored port information and the port matching condition, and in the embodiment of the present application, a method for reasonably allocating service ports according to service types, current loads, and priorities is provided, and a method for determining dedicated service ports of some users according to user types is also provided, so as to implement port-level service discovery. Then the NRF sends the network element information of the target NF and the port information of the target service port to the source NF, and the source NF requests the service from the target NF according to the received network element address and the port information and receives the service provided by the target NF. Under the condition that the NF is provided with a plurality of service ports, the embodiment of the application realizes the service discovery at the port level according to the port information and the port matching condition, thereby realizing the reasonable distribution of NF port resources, effectively solving the network congestion and the resource waste caused by the random distribution of the service ports by the NRF and being beneficial to improving the service processing efficiency of the core network.
