Description

Technical Field

[0001] The present invention relates to the field of mobile communication technology, and in particular to a core network service message routing fusion selection method, device and server. Background Art

[0002] Service-based Architecture (SBA) is a key feature of the core network of fifth-generation mobile communication systems. Drawing on the concept of service-oriented information systems and in line with the network characteristics and technological development trends of mobile core networks, SBA achieves decoupling and integration of network functions through modularization. Each decoupled network function can be independently expanded, evolved, and deployed on demand. Network functions are divided into reusable services that communicate using service-based interfaces (SBIs). Services are divided into two roles: producers and consumers. The interaction model is the request-response model. In this model, a network function service consumer requests a specific network function service from a network function service producer. The service content may be to perform an operation or provide information. The network function service producer returns the corresponding service results based on the request content sent by the network function service consumer.

[0003] The same type of producer service can have multiple running instances, namely, network function service instances. A core network includes multiple network functions. In the network function operating environment, the network function service instance is the basic operating unit. The life cycle and load conditions of each network function service instance are different. If a network function consumer randomly routes a network function service request to a network function service instance, and the selected network function service instance fails to process the network function service request due to reasons such as failure or high load, then at this time, there is a network function service instance in the core network that can handle the network function service request, and it does not get the opportunity to process the serviced message, resulting in a decrease in the throughput and reliability of the entire core network system.

[0043] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0044] The following combination Figure 1-Figure 4 The present invention describes the core network service message routing fusion selection method, device and server.

[0045] like Figure 1 As shown, the present invention provides a core network service message routing fusion selection method, comprising:

[0046] Step 110: Obtain a target network function service instance set, and determine a business load value and a resource load value based on the target network function service instance set.

[0047] Among them, the business load value is determined based on the business monitoring parameters and configuration planning parameters of the network function service instance; the resource load value is determined based on the resource monitoring parameters and configuration planning parameters of the network function service instance.

[0048] It is understood that when a network function service instance is started, the configuration planning parameters of the network function service instance are obtained. The configuration planning parameters can be obtained based on the following two methods: Method 1, obtaining the network function configuration planning parameters through the network function resource template file; Method 2, obtaining the configuration planning parameters corresponding to the network function service instance through the open application programming interface (API) provided by the network function service instance.

[0049] The service monitoring parameters of the network function service instance are obtained at a preset period. There are two methods for obtaining the service monitoring parameters: Method 1: Obtain the service monitoring parameters reported by the network function service instance through the performance statistics gateway of the network function operation platform. Method 2: Obtain the service monitoring parameters of the network function through the open application programming interface provided by the network function service instance.

[0050] Obtain the resource monitoring parameters of the network function service instance according to the preset period, and obtain the resource usage corresponding to the network function service instance through the performance statistics gateway of the network function operation platform.

[0051] Step 120: Determine the load value of the network function service instance in the target network function service instance set based on the business load value and the resource load value.

[0052] It can be understood that the load value of the network function service instance in the target network function service instance set is calculated based on the business load value and the resource load value, as well as the preset weight value, the number of received messages and the number of message processing failures.

[0053] Step 130: Determine a weight of the network function service instance based on the load value of the network function service instance, and determine the number of service messages routed to the network function service instance based on the weight of the network function service instance.

[0054] It is understood that network function request messages can be routed to different network function service instances based on weights. The higher the weight, the more service messages are routed to the network function service instance.

[0055] In some embodiments, obtaining a target network function service instance set includes:

[0056] An initial network function service instance set is obtained, and when it is determined that a new network function service instance is online, the new network function service instance is merged into the initial network function service instance set to obtain the target network function service instance set.

[0057] It can be understood that this embodiment can monitor in real time whether there is a new network function service instance online. If there is a new network function service instance online, the initial network function service instance is iteratively updated based on the new network function service instance.

[0058] In some embodiments, obtaining the target network function service instance set further includes:

[0059] When it is determined that a network function service instance is offline, the offline network function instance is deleted from the target network function service instance set.

[0060] It can be understood that when it is determined that a network function service instance is offline, the offline network function instance is deleted from the target network function service instance set, and the target network function service instance set is updated to determine the business load value and resource load value based on the updated target network function service instance set.

[0061] In some embodiments, the configuration planning parameters include: user number capacity, session number capacity and base station connection capacity; the service monitoring parameters include: number of users, number of sessions and number of base station connections.

[0062] It is understandable that the configuration planning parameters, including user capacity, session capacity, base station connection capacity, CPU limit, memory limit, and hard disk limit, are static data and do not change with the load of the network function service instance.

[0063] Business monitoring parameters, including the number of users, number of sessions, number of base station connections, number of received messages, number of sent messages, and number of message processing failures, are dynamic data and change dynamically based on the actual business processing load of the network function service instance.

[0064] In some embodiments, the traffic load value is calculated based on the following formula:

[0065] D b =[1-(C u -B u ) / C u ]+[1-(C s -B s ) / C s ]+[1-(C nb -B nb ) / C nb ];

[0066] Among them, D b is the traffic load value, C u is the user capacity, B u is the number of users, C s is the session capacity, B s is the number of sessions, C nb is the base station connection capacity, B nb is the number of base station connections.

[0067] It can be understood that, from the candidate network function service instances, the difference between the business monitoring parameters and the corresponding configuration planning parameters of each network function service instance is calculated, and the difference represents the load of the network function service instance from the business dimension. b When the value is 0, it means that the network function service instance has no load. b A value of 3 indicates full load, D b A value greater than 3 indicates overload.

[0068] In some embodiments, the resource monitoring parameters include: CPU usage, memory usage, and hard disk usage.

[0069] It is understood that resource monitoring parameters, including CPU usage, memory usage, and disk usage, are dynamic data that reflects the dynamic changes in the network function service instance at the resource level (CPU, memory, and disk usage consumed during operation).

[0070] In some embodiments, the resource load value is calculated based on the following formula:

[0071] D r =[1-(Cp -R c ) / C p ]+[1-(C m -R m ) / C m ]+[1-(C d -R d ) / C d ];

[0072] Among them, D r is the resource load value, C p is the CPU limit, R c is the CPU usage, C m is the memory limit, R m is the memory usage, C d is the hard disk limit, R d The hard disk usage.

[0073] It can be understood that, from the candidate network function service instances, the difference between the computing resource monitoring parameters and the corresponding configuration planning parameters of each network function service instance is calculated, and the difference represents the load of the network function service instance from the resource dimension. r When the value is 0, it means that the network function service instance does not occupy running resources. r A value of 3 indicates that the running resources have reached the maximum value of the planned resources used by the network function service instance. r A value greater than 3 indicates that resource usage exceeds the limit.

[0074] In some embodiments, determining the weight of the network function service instance based on the load value of the network function service instance, and determining the number of service messages routed to the network function service instance based on the weight of the network function service instance, includes:

[0075] Summing the load values of the network function service instances in the target network function service instance set to obtain a total load value;

[0076] Based on the ratio of the load value of the network function service instance to the total load value, the weight of the network function service instance is obtained, so as to determine the number of service messages routed to the network function service instance based on the weight of the network function service instance.

[0077] It is understood that the weight of a network function service instance is calculated as follows:

[0078]

[0079] Among them, V i is the load value of the ith network function service instance; NFw iis the weight of the i-th network function service instance, and n is the number of network function service instances in the target network function service instance set.

[0080] From the set of target network function service instances, the load value of each network function service instance is calculated, and the weight of each network function service instance is calculated. Network function request messages can be routed to different network function service instances based on the weight. The higher the weight, the more service messages are routed to this network function service instance.

[0081] In some embodiments, determining the load value of the network function service instance in the target network function service instance set based on the traffic load value and the resource load value includes:

[0082] Sum the first product, the second product, and the third product to obtain a load value of the network function service instance in the target network function service instance set;

[0083] Among them, the first product is the product of the business load value and the first preset weight; the second product is the product of the resource load value and the second preset weight; the third product is the product obtained by dividing the number of message processing failures by the number of received messages and then multiplying it by the third preset weight.

[0084] It is understandable that the load value of the network function service instance in the target network function service instance set is calculated based on the following formula:

[0085] V i =D b *w1+D r *w2+B f / B r *w3;

[0086] Among them, w1, w2, and w3 are the first weight, second weight, and third weight respectively, which can be set according to the actual operation of the 5G core network; V i is the load value of the i-th network function service instance. f is the number of message processing failures, B r is the number of received messages.

[0087] In other embodiments, the core network service message routing fusion selection method provided by the present invention is as follows: Figure 2As shown, first determine whether a new network function service instance has come online. If so, merge the new network function service instance into the initial network function service instance set to obtain the target network function service instance set. Then determine whether a network function service instance has gone offline. If so, delete the offline network function service instance from the target network function service instance set. Based on the target network function service instance set, calculate the service load value, calculate the resource load value, calculate the load value of each network function service instance, and calculate the weight of each network function service instance.

[0088] In summary, the core network service message routing fusion selection method provided by the present invention includes: obtaining a target network function service instance set, and determining a business load value and a resource load value based on the target network function service instance set; determining the load value of the network function service instance in the target network function service instance set based on the business load value and the resource load value; determining the weight of the network function service instance based on the load value of the network function service instance, and determining the number of service messages routed to the network function service instance based on the weight of the network function service instance; wherein the business load value is determined based on the business monitoring parameters and configuration planning parameters of the network function service instance; and the resource load value is determined based on the resource monitoring parameters and configuration planning parameters of the network function service instance.

[0089] In the core network service message routing fusion selection method provided by the present invention, the service load value and the resource load value are determined by the configuration planning parameters, service monitoring parameters and resource monitoring parameters of the target network function service instance set, and the load value of the network function service instance in the target network function service instance set is further determined. Then, based on the load value of the network function service instance, the weight of the network function service instance is determined, and the number of service messages routed to the network function service instance is determined based on the weight of the network function service instance, so as to avoid the failure of service message processing caused by uneven load sharing of the network function service instance, thereby improving the core network service message processing throughput and reliability.
