Detailed Description
The embodiment of the application provides an information transmission method and device and a computer storage medium, which are used for sending load information of an NF entity to the NRF entity, so that the NRF entity can obtain the load information of the NF entity, the load information of the NF entity on a discovered side can be conveniently provided for the NF entity on the discovered side through a service discovery process subsequently, the NF entity on the discovered side can select a better NF entity to establish a session and a service based on the load information of the NF entity on the discovered side, and unbalanced network resource distribution is avoided.
In a 5G core network, an NRF entity is an important network element for serving, and provides functions such as service registration, de-registration, service discovery, and service selection. The service discovery function of the NRF entity may screen out a functional device (NF entity) having the same Information (e.g., Data Network Name (DNN) and Single Network Slice Selection Information (S-NSSAI)) according to the identifier of the request, and return a corresponding full path domain Name (FQDN) or IP address to the requester.
According to this principle, the service discovery process may perform a conditional search on devices that satisfy the condition and return the result. The embodiment of the application provides that the load condition of the network element can be dynamically updated in the registration process of the keep-alive heartbeat, so that each network element can obtain the latest load state of other network element equipment. And in the function of service selection, a proper network element is selected in the discovery process by combining the load condition of the network element, so that the load sharing and load balancing among the network elements are ensured.
The following illustrates a specific technical solution provided in the embodiments of the present application.
First, the NF entity dynamically sends the load situation to the NRF entity in a registration message. The following are added in the message transmitted between the network elements: the number of users and the load ratio; the number of users may include, for example, a maximum capacity (a maximum number of users supported), and/or a number of users currently providing services.
The definition of the duty ratio is as follows:
if the NF entity is an Access and Mobility management function (AMF) entity, the load information sent by the AMF entity to the NRF entity may include one or a combination of the following information:
the maximum number of supported users is 100000;
the number of users 70000 in use, that is, the number of users 70000 currently providing services;
the load accounts for 70% (percent).
If the NF entity is a Session Management Function (SMF) entity, the load information sent by the SMF entity to the NRF entity may include one or a combination of the following information:
the maximum number of sessions supported is 100000;
number of sessions in use 60000;
the load ratio (percentage) is 60%.
In the registration process, each network element (i.e. NF entity) dynamically keeps calculating, and the following 10 threshold values are respectively preset for the load ratio:
10％；20％；30％；40％；50％；60％；70％；80％；90％；100％。
then, the triggering condition for reporting the load ratio is, for example: when the next threshold is reached, triggering to report the current load ratio to the NRF entity (of course, other related information may be reported at the same time in addition to the load ratio), for example, reporting the latest load ratio once when the load ratio reaches 10% of the threshold, and as the number of users increases, the load ratio becomes larger correspondingly, and when the load ratio reaches 20% of the next threshold, reporting the latest load ratio again is required, and so on.
It can be seen that the next threshold is relative to the threshold referred to in the last reporting of the duty ratio.
If the NF entity does not report the load ratio, namely the load ratio does not reach the next threshold value, the NRF entity does not need to modify the stored load ratio corresponding to the NF entity. Subsequently, in the service discovery process, the NRF entity may also send the information of the discovered NF entity, such as the number of users, load ratio, etc., to the service requester NF entity for the service requester NF entity to refer to for service selection.
Referring to fig. 1, a registration process provided in the embodiment of the present application includes:
step 1, before each network element (NF entity) periodically sends a Registration Request (NF Registration Request) to the NRF entity, it calculates whether the current load ratio (the ratio of the currently used user number to the maximum user number that can be supported) exceeds a next threshold, and if so, the total number of users (which may be the currently used user number and/or the maximum user number that can be supported) and the load ratio information are carried in the Registration Request message. If the load ratio is not changed or does not exceed the next threshold value, the load information such as the load ratio does not need to be carried in the registration request.
Step 2, after receiving the NR Registration Request message, the NRF entity stores the information in the message. And if the message carries load information such as the total number of users, the load ratio and the like, storing the load information in the instance information corresponding to the network element equipment.
And 3, the NRF entity replies an NF Registration Response message, wherein the carried content can inform the NF entity of the success of keep-alive Registration and other related information.
With respect to the service discovery process, referring to fig. 2, the method specifically includes:
the registration process initiated by the first NF entity NF1 and the second NF entity (for example, including two NF entities NF2_1 and NF2_2, respectively) to the NRF entity is the same as the flow shown in fig. 1, and is not described herein again.
The first NF entity NF1 acts as a service requester, initiates a service Discovery procedure, and sends a Discovery request message (nrrf _ NF Discovery _ request) to the NRF entity. Meanwhile, referring to fig. 3, the NRF entity filters the load condition of the network element meeting the condition according to the recorded load information of the NF entities, determines that two second NF entities meeting the condition are NF2_1 and NF2_2, respectively, for example, a threshold value of 90% is set on the NRF, and the load ratio of NF2_1 and NF2_2 does not exceed 90%, and sends related information of the two second NF entities to the first NF entity NF1 through a Discovery response message (NRF _ NF Discovery _ response), where the information includes FQDN or IP address information of the two second NF entities, and the information about the number of users and the load ratio. If the load occupation ratio of all the NF entity devices exceeds 90%, optionally, the NRF entity selects the information about the NF entity with the lightest load to reply to the first NF entity, and sends a full load alarm indication to the system alarm unit. In addition, the network element type described in fig. 3 refers to a network element classification classified by service function, such as AMF, SMF, UDM, and the like. The NF equipment is searched according to the authorization rule, and then the NF equipment can be selected from the corresponding network element equipment according to the network element type to be found. Such as the need to discover an AMF, the AMF is selected from a plurality of AMF devices.
Meanwhile, referring to fig. 4, after the first NF entity NF1 (e.g. AMF) of the service requester receives the FQDN or IP address information of the second NF entity (e.g. SMF) NF2_1 and NF2_2, and the user number and load ratio information, the second NF entity (possibly multiple NF entities) with the lightest load is selected for service interaction. If a plurality of second NF entities with the minimum load ratio exist, selecting the second NF entity with the maximum number of the remaining users; if a plurality of second NF entities with the largest number of remaining users exist, the second NF entity with the highest version can be selected, and then the network resources can be utilized most reasonably. After the selection is completed, the first NF entity NF1 sends a service message, for example, a packet data unit Session Establishment Request (PDU Session Establishment Request), to the selected second NF entity.
And optionally, if the first NF1 finds that the load ratios of the second NF entities NF2_1 and NF2_2 both exceed the preset threshold value, selecting the second NF entity with the lightest load for service interaction, and sending a full load alarm indication to the system alarm unit.
In addition, optionally, after the first NF entity NF1 (e.g. AMF) receives the FQDN or IP address information of the second NF entity (e.g. SMF) NF2_1 and NF2_2, and the information of the number of users and the load ratio, it may first determine whether the loads of NF2_1 and NF2_2 are full, or if both are full, it may not select any second NF entity.
It should be noted that any one of the threshold values in the embodiments of the present application may be determined according to actual needs, and specific values are not limited.
