Embodiments of the present application are described below in conjunction with the drawings in the present application. It should be understood that the embodiments set forth below in connection with the drawings are exemplary descriptions for explaining technical solutions of the embodiments of the present application, and do not limit the technical solutions of the embodiments of the present application.

It should be further understood that the terms "comprises" and/or "comprising," when used in this specification in connection with embodiments of the present application, specify the presence of stated features, information, data, steps, operations, elements, and/or components, but do not preclude the presence or addition of other features, information, data, steps, operations, elements, components, and/or groups thereof, as embodied in the art. It will be understood that when an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements may be present. Further, "connected" or "coupled" as used herein may include wirelessly connected or wirelessly coupled. The term "and/or" as used herein indicates at least one of the items defined by the term, e.g., "a and/or B" may be implemented as "a", or as "B", or as "a and B".

To make the objects, technical solutions and advantages of the present application more clear, the following detailed description of the embodiments of the present application will be made with reference to the accompanying drawings.

In a 5G core network, AMF (Access and mobility Management Function) and SMF (Session Management Function) are two important control plane network elements. The AMF is responsible for the access and mobility management functions of the user equipment; the SMF network element is responsible for session management of a User, address allocation of a terminal device, selection of a UPF (User Plane Function) network element, and tunnel establishment. In one network, there are a plurality of AMFs and SMFs.

Fig. 1 shows a scene diagram of session creation based on a 5G core network. In this scenario, the process of creating a session is specifically as follows: UE sends control plane signaling to AMF through N1 interface, or AN sends control plane signaling to AMF through N2 interface; after receiving any control plane signaling, the AMF needs to select an adaptive SMF from the multiple SMFs, and select a UPF from the adaptive SMF to perform session flow creation. The 3gpp 23.501 protocol describes the general procedure and method for selecting an adaptive SMF, and a plurality of factors that may affect the selection result, including the load of the SMF. For example, for several SMFs that all satisfy the condition, the SMF with the higher residual load should be selected as much as possible, and the SMF with the higher residual load has a greater probability to be selected. In order to be able to select an SMF based on "load", the AMF needs to acquire load information of the SMF in advance.

Currently, the protocol provides that each NF (Network element) must register with an NRF (Network Repository Function) to provide services when it is started. Each NF provides NFProfile of the NF at registration, and the NFProfile at least includes the following contents: NFtype, NF instance ID, NF capacity, IP address of NF, slice information supported by NF, PLMN ID (Public Land Mobile Network, which can uniquely identify a communication operator) of NF, etc. After registering, each network element reports changes such as supported function updates and device offline to the NRF. When each network element is registered, it may also notify the NRF of the NF of interest, and the NRF may pay attention to and notify when any new NF is registered (for example, when the AMF is registered, it notifies the NRF of the network element of interest being the SMF).

Fig. 2 shows a 5G system architecture in which AMF, SMF and NRF are connected, and NRF accepts registration of AMF and NRF. When the SMF is registered, the NFProfile may further include load information of the SMF; when registering in the AMF, the AMF may also send an interested network element as an SMF to the NRF, and once there is an SMF registration, the AMF can know, and the AMF can obtain load information of the SMF by acquiring NFProfile of the SMF.

However, the protocol specifies the load information in NFProfile as padding information, that is, NFProfile may not have compliance information. If the NFProfile does not include the load information, the AMF cannot acquire the load information of the SMF through the NRF. In addition, there is a 5G system architecture in which NRFs may not be deployed. Therefore, without NRF deployment, load information of SMF cannot be acquired.

The embodiment of the present application provides a method for acquiring network element information, so as to solve one of the above technical problems. The method may be applicable to a plurality of network elements in a 5G system architecture, such as a first network element (e.g., AMF) and a second network element (e.g., SMF). Specifically, the method comprises the following steps: the first network element sends an interaction request to the second network element; after receiving the sent interactive request, the second network element performs transaction processing, and if the processing result is successful, feeds back an interactive result carrying a target field and corresponding information to the first network element, wherein the information corresponding to the target field comprises at least one item of target information describing the second network element; after the first network element receives the interaction result, the interaction information of the second network element can be obtained. The method obtains the target information through normal interaction processing, and avoids that the target information of the second network element can be obtained through a direct interaction mode with the second network element when the NRF is not configured or the target information of the second network element is not in the NRF, so that the daily service processing can be executed according to the obtained target information.

Optionally, the method provided in this embodiment of the present application is based on a 3gpp 23.501 protocol, and is implemented to improve multiple pieces of structured data defined in the 3gpp29.502 protocol, such as the following structured data: the session management context has created data (smcontextcreatedata), the session management context has updated data (SmContextUpdatedData), and the session management context has released data (smcontextthreadeddata).

In order to make the technical solutions provided by the present application clearer, the following describes the technical solutions of the embodiments of the present application and the technical effects produced by the technical solutions of the present application through the description of several exemplary embodiments. It should be noted that the following embodiments may be referred to, referred to or combined with each other, and the description of the same terms, similar features, similar implementation steps and the like in different embodiments is not repeated.

Fig. 3 is a flowchart illustrating a method for acquiring network element information according to an embodiment of the present application. Wherein the method is applied to a first network element. As shown in fig. 3, the method includes steps S310 to S320.

S310, the interactive request is sent to the second network element.

S320, if receiving an interaction result carrying a target field fed back by the second network element based on the interaction request, acquiring information corresponding to the target field from the interaction result; the information corresponding to the target field includes at least one item of target information describing the second network element.

Optionally, the target field includes a time field and other fields. Wherein, the time information corresponding to the time field is the time for describing the target information corresponding to other fields provided by the second network element.

In an optional embodiment, the first network element is an AMF, and the second network element is an SMF.

Alternatively, one AMF may be connected to one or more SMFs.

Optionally, a session management context needs to be constructed between each AMF and SMF.

Optionally, the interactive request may be any one of the following requests: creating a session request, updating a session request, and releasing a session request.

Creating a session request: the interaction result includes session management context created data, which includes the target field.

Optionally, the target field includes a field describing load information, and the target information includes the load information. It should be noted that the target information may also include other types of information.

Specifically, if the AMF selects the target SMF as the SMF of the session creation flow, the AMF sends a session creation request to the target SMF to create the session management context. The session creation request carries information of the mobile phone side and the base station side, such as SUPI, PLMN, access protocol type (4G/5G), and location of the terminal. The target SMF creates a session management context upon receiving the create session request. And if the session is successfully established, feeding back the established data of the session management context. The session management context created data includes load information at the current time and a timestamp at the current time. The session management context created data also includes information of the created session, such as a session ID, and the like.

Optionally, if the creation fails, session creation failure information is fed back.

Referring to the flowchart of an interactive request shown in fig. 4 for example, in the interactive scenario, the interactive scenario includes step 1 and step 2, step 1 is that the AMF sends an interactive request to the SMF, and step 2 is that the SMF sends feedback to the AMF according to the interactive request.

With reference to fig. 4, step 1: the AMF sends a session creation request to the SMF to request creation of a session management context. Step 2: and the SMF carries out session creation according to the session creation request to obtain the created data of the session management context, and feeds back the created data of the session management context to the AMF. The session management context created data includes load information load at the current time and a current timestamp loadTimeStamp.

Updating the session request: the interaction result includes session management context updated data, the session management context updated data including the target field.

Specifically, if the AMF knows that the information of the SMF is updated, the AMF sends an update session request to the SMF. The SMF updates the corresponding session management context after receiving the update session request. The update session request carries various parameters, such as PLMN, access type (2G/3G/4G/5G), location of the ue, time zone, etc. And if the updating is successful, obtaining the updated data SmContextUpdateData of the session management context, and feeding back the updated data of the session management context to the AMF in the form of the updated data of the session management context. The updated data of the session management context includes load information load at the current time and a current timestamp loadTimeStamp.

Alternatively, if the user terminal changes from base station 1 to base station 2, the base station information in the corresponding session management context needs to be adjusted. The adjustment may involve updating of load information of the SMF.

Illustratively, after designating the target SMF as the SMF that creates the session flow, the AMF will proactively send a request to the target SMF to modify the load information of the target SMF. And after receiving the request, the target SMF determines the session management context to be updated according to the request and updates the session management context. Since each session management context may take a certain load in the SMF. If the session management context is updated, the load information of the SMF is updated.

Referring again to fig. 4, step 1: the AMF sends an update session request to the SMF to request an update of the corresponding session management context. And 2, after receiving the session updating request, the SMF acquires the corresponding session management context and updates the session management context to obtain updated data of the session management context. The session management context created data includes load information load at the current time and a current timestamp loadTimeStamp.

Releasing the session request: the interaction result includes session management context released data, which includes the target field.

Specifically, if the AMF learns that the user terminal has terminated the session service, the AMF sends a session release request to the target SMF to release the corresponding session management context. Wherein, the session release request carries information such as session ID. And after receiving the session release request, the target SMF releases the corresponding session management context. And if the release is successful, feeding back the released data of the session management context. The session management context released data includes load information at the current time and a timestamp at the current time.

Referring again to fig. 4, step 1: the AMF sends a session release request to the SMF to request that the corresponding session management context be released. And 2, step: the SMF performs a release operation according to the session ID carried in the session creation request to obtain session management context released data (smcontextriesseddata), and feeds back the session management context created data to the AMF. The session management context created data includes load information load at the current time and a current timestamp loadTimeStamp.

Since the session creation/update/release operation is the most frequent operation between the AMF and the SMF, the load information of the SMF at the current time can be obtained once every time any one of the above operations is performed, so as to obtain the latest load information of the SMF, and the adaptive SMF can be selected for the control plane signaling sent by various user terminals through the latest load information. Wherein SmContextCreatedData is obtained after the session creation operation is carried out; smContextUpdatedData is obtained after the session update operation, and SmContextTreleedData is obtained after the session release operation. By carrying the load information load of the SMF at the current time in the various data and the current timestamp load timestamp, the purpose of feeding back the latest load information can be realized.

In an optional embodiment, the method may further comprise:

comparing the received time information with current historical time information; the historical time information is the time for describing that the second network element obtains the historical target information corresponding to other fields; and if the comparison result is different, storing the received time information and the target information. And if the comparison result is the same, abandoning to store the target information.

Optionally, after the information corresponding to the target field is obtained from the interaction result, storing the target field and the corresponding target information is further included. After the storage, the time information is updated to the historical time information, and the target information is updated to the historical target information.

Alternatively, the historical time information may exist in plural. The current historical time information is the time corresponding to the time field closest to the current time.

The embodiment of the application provides a method for acquiring network element information, which is applied to a first network element and comprises the following steps: and the first network element sends an interaction request to the second network element and waits for the feedback of the second network element. If an interaction result which carries the target field and is fed back by the second network element based on the interaction request is received, acquiring corresponding information of the target field from the interaction result; wherein the information corresponding to the target field includes at least one item of target information describing the second network element. According to the method in the embodiment of the application, when no NRF network element is configured in the network or NRF does not provide the target information of the second network element, the target information of the second network element can be acquired in a direct interaction manner with the second network element, so that daily service processing can be executed according to the acquired information of the second network element.

In the 5G system architecture, there are other combinations of network elements besides such a combination of AMF and SMF. Such as SMF and UDM, SMF needs to acquire information stored in UDM in order to perform session creation; for example, SMF and PCF, SMF needs to obtain information of multiple PCFs to determine which PCF sends the control policy to perform session control. In the related art, the problem of how to acquire UDM and PCF information is generally solved by configuring NRFs. Based on the scheme provided by the embodiment of the application, the information can be acquired through interaction between the two network elements. Taking SMF and UDM as examples, when UDM feeds back the interaction result to SMF, time information and information corresponding to other fields may also be added to the feedback result to feed back the target information.

Fig. 5 is a flowchart illustrating another method for acquiring network element information according to an embodiment of the present application. Wherein the method is applied to the second network element. As shown in fig. 5, the method includes steps S510 to S520.

S510, performing a transaction process in response to the interaction request sent by the first network element.

Optionally, if a session creation request is received, creating a corresponding session management context; if receiving a request for updating the session, updating the corresponding session management context; and if receiving the session release request, releasing the corresponding session management context.

S520, if the processing result is successful, feeding back an interaction result carrying the target field and corresponding information to the first network element; the information corresponding to the target field includes at least one item of target information describing the second network element.

Specifically, target information corresponding to other fields is obtained, and time information corresponding to the operation is obtained; comparing the obtained target information with historical target information; the historical target information is the target information obtained last time; if the comparison result is not within the preset range, carrying the time information corresponding to the acquisition operation and the acquired target information in the interaction result; if the comparison result is within the preset range, carrying the historical target information and the time information for acquiring the historical target information in the interaction result; and feeding back the interaction result to the first network element.

Optionally, after the target field and the corresponding target information are sent each time, the target field and the corresponding target information are stored, and the stored target information is history target information.

Optionally, if the information corresponding to the target field is numerical value information, subtracting a numerical value corresponding to the target information from a numerical value corresponding to the historical target information to obtain a difference value. A difference range is preset, namely the preset range. If the difference value is not within the range of the difference value, carrying the current time and the obtained target information in the interaction result; and if the difference value is within the range of the difference value, carrying the historical target information and the time corresponding to the historical target information in the interaction result. And the time corresponding to the historical target information is the time for acquiring the historical target information.

Optionally, if the difference is within the range of the difference, it may also be selected not to carry any target information in the interaction result.

To avoid notifying the AMF of every change, a difference range may be set, and the AMF is notified of the interaction result after the load change exceeds the difference range.

In an optional embodiment, the first network element is an AMF, and the second network element is an SMF. The target field comprises a load information field, and the information corresponding to the information field is the load information of the second network element. Acquiring target information corresponding to other fields, which may specifically include:

Optionally, processing is performed according to the current CPU usage information, memory usage information, and the number of currently accessed users, so as to obtain a numerical value. Wherein the value ranges from 0 to 100. Where 0 represents the minimum load and 100 represents the maximum load. Thus, the load information may be a comprehensive indicator.
