This information is called roaming guide information.

If the selected PLMN is a Visited network (VPLMN), the HPLMN may provide SoR information to the UE during or after registration of the UE with the network. If the selected PLMN is the HPLMN, the HPLMN may provide SoR information to the UE only after the UE registration is complete.

The HPLMN updates the "operator controlled selected PLMN/access technology" list according to an operator policy, which may be determined based on the registered VPLMN, the location of the UE, etc.

And the V-NWDAF performs data analysis according to the received data information from the VPLMN1 NF and/or the OAM to obtain network performance prediction information of the VPLMN and/or terminal behavior analysis information.

The V-NWDAF sends network performance prediction information of the VPLMN and/or terminal behavior analysis information to the H-NWDAF. The H-NWDAF acquires network performance prediction information of a plurality of VPLMNs and/or terminal behavior analysis information, and sends the information to SoR AF or UDM.

According to the method for determining the roaming guide information, provided by the embodiment of the application, the network performance prediction information of a plurality of networks which can be accessed by the terminal in the roaming scene and/or the terminal behavior analysis information of the terminal in the roaming scene are obtained, so that better roaming guide information is provided for the terminal, the network or the access technology with better performance is selected by the UE, the communication requirements of the UE are better met, and the network selection, the access and the communication performance of the UE in the roaming scene are improved.

Specifically, after the first network functional entity obtains the first information and/or the second information, the roaming guide information is determined, which specifically includes:

the first information is network performance prediction information, and the second information is terminal behavior analysis information.

And when the first information is acquired but the second information is not acquired, ordering the network and/or the access technology in the roaming scene according to the network performance based on the first information, and determining the roaming guide information. For example, by means of a list, for different networks or different access technologies, the network performance corresponding to the network performance prediction information is ordered from high to low as roaming guide information.

And when the second information is acquired but the first information is not acquired, ordering the network and/or the access technology in the roaming scene according to the matching condition with the terminal behavior based on the second information, and determining the roaming guide information. For example, a network/access technology that covers a terminal location area and is capable of covering a movement track of a roaming terminal is preferable. For example, a network/access technology capable of supporting communication requirements/application requirements/service requirements of a roaming terminal is preferable.

And when the first information and the second information are acquired, the network and/or the access technology in the roaming scene are ordered according to the network performance and the matching condition with the terminal behavior based on the first information and the second information, and the roaming guide information is determined. For example, for a network/access technology capable of covering a moving track of a roaming terminal, satisfying a roaming terminal communication requirement/service requirement/application requirement, a network/access technology in which performance is higher is preferable, further ordered from high to low in network performance. For example, after the network/access technologies are arranged according to network performance, the network/access technologies with higher performance are preferable, which can cover the movement track of the roaming terminal and meet the communication requirements/service requirements/application requirements of the roaming terminal.

Specifically, the first network functional entity is SoR AF or UDM.

Specifically, the second network functional entity is a network data analysis functional entity of the visited network, and the third network functional entity is a network data analysis functional entity of the home network. In one possible implementation, the second network function entity is a network data analysis function entity, and the third network function entity is not a network data analysis function entity. In one possible implementation, the second network function entity is not a network data analysis function entity, and the third network function entity is a network data analysis function entity.

Specifically, the second network function entity of the visited network determines network performance prediction information (i.e., first information) of a network that the terminal can access in the roaming scenario, and/or obtains terminal behavior analysis information (i.e., second information) of the terminal in the roaming scenario. The number of roaming terminals may be one or more.

After the second network function entity determines the first information and/or the second information, the second network function entity sends the first information and/or the second information to the first network function entity of the home network, so that the first network function entity determines roaming guide information according to the first information and/or the second information, and the roaming guide information is used for guiding the terminal to conduct network selection in a roaming scene.

(2) And receiving a first request message indirectly sent by the first network function entity, and sending the first information and/or the second information to the first network function entity based on the first request message. Indirect sending refers to forwarding the first request message intermediately via a third network function entity of the home network. The specific flow is that the first network functional entity firstly sends a second request message to a third network functional entity of the home network, wherein the second request message is a network analysis request message. And the third network function entity receives the second request message, determines a second network function entity of the visiting network according to the identifier of the visiting network carried in the second request message, and sends the first request message to the second network function entity of the visiting network.

(9) An identification of the home network.

In the flow of indirect forwarding, the second request message includes, in addition to one or more items of information carried in the first request message, an identifier of the visited network.

Specifically, the first information and/or the second information sent by the second network function entity to the first network function entity is forwarded by the third network function entity of the home network.

The specific flow is that the second network functional entity receives the first request message sent by the third network functional entity of the home network. The first request message is sent to a second network function entity according to the identification of the visiting network after a third network function entity of the home network receives a second request message sent by the first network function entity.

Specifically, after receiving the first request message sent by the first network function entity, the second network function entity determines whether to authorize the first request message, if so, determines the first information and/or the second information, and sends the first information and/or the second information to the first network function entity.

The specific process of determining the first information and/or the second information may include: the second network function entity sends a data collection request to the network function entity or OAM of the visiting network based on the first request message, requests related data of network/access data of the visiting network and/or related data of mobility characteristics or communication characteristics or service application characteristics of roaming UE in the VPLMN, analyzes and obtains first information and/or second information, and sends the first information and/or the second information to the first network function entity.

In case the first request message contains a region of interest, the first information and/or the second information is the first information and/or the second information within the region of interest.

And under the condition that the first request message contains the access technology information, the first information and/or the second information are the first information and/or the second information under the access technology corresponding to the access technology information.

And under the condition that the first request message contains the network slice information, the first information and/or the second information are the first information and/or the second information in the network slice corresponding to the network slice information.

Specifically, after receiving the network analysis request, the second network function entity sends a data acquisition request to a network function entity (such as V-NRF, V-AMF, V-SMF) and/or OAM of the visited network, requests first data (related data of a network/access technology of the visited network) for characterizing network performance, performs data analysis based on the first data, and determines first information. And/or, requesting second data (related data of mobility characteristics or communication characteristics or service application characteristics of roaming UE in the visiting network) for characterizing the terminal behavior, and performing data analysis based on the second data to determine the second data.

In the method for determining the roaming guide information provided by the embodiment of the application, in the process of determining the roaming guide information, besides the policy requirement of an operator, the communication requirement of the terminal and the network performance of the selected network/access technology are considered, and the network selection, access and communication performance of the UE in a roaming scene are improved by acquiring the network performance prediction information of the network which the terminal can access in the roaming scene and/or the terminal behavior analysis information of the terminal in the roaming scene, so that better roaming guide information is provided for the terminal, the network or the access technology with better performance is selected by the UE, the communication requirement of the UE is better met, and the network selection, access and communication performance of the UE in the roaming scene are improved.

It should be noted that, the above method for determining the roaming guide information using the second network function entity as the execution body and the above method for determining the roaming guide information using the first network function entity as the execution body are based on the same inventive concept, and the related preset conditions, the content and the beneficial effects carried in the message may be referred to each other, which is not repeated herein.

The technical scheme of the embodiment of the application is further described below through specific examples.

Example one: SOR AF acquires network performance analysis information of PLMN

Fig. 3 is a third flowchart of a method for determining roaming guide information according to an embodiment of the present application, where, as shown in fig. 3, the method at least includes the following steps:

step 301, the SOR AF sends a network analysis request to the H-NWDAF, requesting the H-NWDAF to provide analysis information of the network/access technology of the VPLMN1 for determining SOR information. Specifically, the analysis request carries the following information:

(1) the analysis identifier corresponds to network performance analysis information and is used for indicating analysis type or identifying specific analysis information, namely: analytics ID= "Network performance information".

Optionally, the requested analysis information may also be service experience analysis information, network slice load level analysis information, user plane data congestion analysis information, and the like, and may also be newly defined "roaming guide" analysis information.

(2) Analyzing the filtered information (Analytics Filter Information), comprising: visited network identification (VPLMN 1 ID), UE location (UE location) and/or Area of Interest (Area of Interest, aoI), access technology information, etc. Other information may also be included, such as: slice information, comprising: the S-NSSAI of the HPLMN, NSI ID of the HPLMN, S-NSSAI of the VPLMN, NSI ID of the VPLMN, etc., represent analysis information requesting a particular network slice.

Wherein the SOR AF may determine the UE location and/or the region of interest in the analysis filtering information by:

(1) The SOR AF acquires the UE location through an application layer or AMF, e.g., the AF subscribes the AMF to the UE location, etc., and determines VPLMNs, e.g., VPLMN1, VPLMN2, and VPLMN3, covering the UE location area.

(2) The SOR AF takes as AoI the overlapping coverage areas of multiple VPLMNs (e.g., VPLMN1, VPLMN2, and VPLMN 3) with roaming agreements with the HPLMN, depending on operator configuration or policy.

The access technology may include: 5G (i.e., new radio access technology (NR)), 4G, wiFi, etc.

The analysis request may also carry the following information:

(3) time period information, which indicates a request for network analysis information over a past or future period of time.

(4) Home network identification, HPLMN ID; alternatively, the user equipment identifies a UE ID, e.g. SUPI, containing the home network identification HPLMN ID of the UE.

In particular, the analysis request may request analysis information once, or subscribe to analysis information multiple times (e.g., request that NWDAF report analysis information at certain periods or upon analysis information update).

Step 302, the H-NWDAF sends an analysis request to V-NWDAF1 in VPLMN1 according to the analysis request received in step 301, requesting V-NWDAF1 to provide analysis information of the network/access technology of VPLMN 1. Specifically, the analysis request carries the following information:

(2) Analysis filtering information, including UE location, aoI, access technology, etc., may also contain other information, such as: S-NSSAI and NSI ID of VPLMN.

(4) Home network identification, HPLMN ID; or, the user equipment identifies a UE ID, e.g. SUPI, containing an identification HPLMN ID of the home network of the UE.

In particular, the analysis request may request one analysis information or subscribe to multiple analysis information, consistent with step 301.

The H-NWDAF may query the visited network storage function (Visited PLMN Network Repository Function, V-NRF) or the visited unified data management (Visited PLMN Unified Data Management, V-UDM) for information of V-NWDAF in VPLMN1 through the home network storage function (Home PLMN Network Repository Function, H-NRF), and then select V-NWDAF1 according to the queried V-NWDAF information.

Step 303, V-NWDAF1 may decide whether to accept or authorize the analysis request based on the HPLMN ID in the received analysis request. If the analysis request is accepted or authorized, the following operations are performed: according to the analysis request, the V-NWDAF1 sends a data collection request to the network function entity NF (e.g., V-NRF, V-AMF, V-SMF) and/or OAM of the VPLMN1, requesting relevant data of the network/access technology of the VPLMN1, for determining corresponding analysis information.

Specifically, the collected data may contain the following data/information: within the UE location area and/or the area of interest:

(1) For a particular PLMN (determined by VPLMN ID identification)

Access performance information: percentage of successful access to PLMN.

Session performance information: the percentage of successful establishment of PDU session in PLMN.

Service/application performance information: performance of services/applications in the PLMN, e.g. service experience (Service Experience), quality of experience (Quality of Experience, qoE).

(2) For a particular access technology in a PLMN (determined by AT identification)

Access performance information: the percentage of successful access to the PLMN using a particular access technology.

Session performance information: the percentage of successful establishment of a PDU session in the PLMN using a particular access technology.

Service/application performance information: the PLMN supports the performance of services/applications with specific access technologies.

Step 304, NF and/or OAM of VPLMN1 sends a data collection response or notification to V-NWDAF according to the data collection request received in step 303, wherein the data collection response or notification includes the data information of the V-NWDAF request, refer to step 303.

Step 305, the V-NWDAF1 performs data analysis according to the received data from the VPLMN1 NF and/or OAM to obtain analysis information of the network/access technology of the VPLMN 1.

In particular, the analysis information may include the following statistical and/or predictive information about VPLMN1 network/access technology performance: within the UE location area and/or the area of interest:

(1) For a particular PLMN (PLMN ID identification determination with VPLMN 1)

Access performance information: percentage of successful access to PLMN.

Service/application performance information: performance of services/applications in the PLMN, such as service experience, quality of experience, etc.

(2) For a particular access technology in a PLMN (determined using AT identification)

Service/application performance information: the performance (e.g., service experience) of services/applications is supported in PLMNs with a particular access technology.

If the analysis request in step 301 contains time period and/or slice information, the analysis information is analysis information of the performance of the network/access technology of the VPLMN1 within the time period and/or the network slice.

Step 306, V-NWDAF1 sends the analysis information of the network/access technology of VPLMN1 to H-NWDAF.

Step 307, H-NWDAF sends analysis information of the network/access technology of VPLMN1 to SOR AF.

Step 308, similar to steps 301-307 described above, the sor AF obtains analysis information of the network/access technology of VPLMN 2.

Step 309, similar to steps 301-307 described above, the sor AF obtains analysis information of the network/access technology of VPLMN 3.

Step 310, SOR AF determines SOR information based on analysis information of the network/access technologies of VPLMN1, VPLMN2 and VPLMN3, namely: the list of "operator controlled selected PLMN/access technology (Operator Controlled PLMN Selector with Access Technology)". In this list, the PLMN/access technology is ranked from high to low performance, with the highest/higher performing PLMN/access technology being the preferred PLMN/access technology.

For example: VPLMN2/5G, VPLMN3/5G, VPLMN1/4G, VPLMN3/WiFi.

Step 311, the SOR AF provides SOR information to the UE. For example: the SOR AF notifies the AMF of SOR information through the UDM, and the AMF transmits the SOR information to the UE.

Step 312, the UE selects a 5G cell of VPLMN2 according to the SoR information, and initiates registration to VPLMN 2.

Example two: UDM obtains network performance analysis information of PLMN

Still referring to fig. 3, the difference from example one is that in example two, the SoR AF in example one is replaced by UDM to perform steps 301, 307-310. In step 311, the UDM provides SoR information to the UE. For example: the UDM notifies the AMF of the SoR information, and the AMF transmits the SoR information to the UE.

Example three: soR AF obtains analysis information of UE in PLMN

Fig. 4 is a flowchart illustrating a method for determining roaming guide information according to an embodiment of the present application, where, as shown in fig. 4, the method at least includes the following steps:

step 401, the UE registers with the roaming network VPLMN1. The UDM informs the SoR AF of the UE roaming status and VPLMN1 ID.

Step 402, the SOR AF sends a network analysis request to the H-NWDAF, requesting to provide the analysis information of the VPLMN1 for the roaming UE. Specifically, the analysis request carries the following information:

(1) an analysis identity for indicating a request for specific analysis information for requesting analysis information on UE movement or communication behaviour/state (or desired UE behaviour), i.e.: analysis id= "UE mobility" or "UE communication".

(2) Analysis of reported targets (Target of Analytics Reporting): UE identity, UE group identity, or any UE indication (i.e., analysis of all UEs meeting the conditions). Wherein the UEs indicated by the target of the analysis report comprise one or more UEs roaming in the VPLMN.

(3) Analyzing the filtered information, comprising: visited network identification (VPLMN 1 ID), UE location and/or region of interest, access technology information, etc. Other information may also be included, such as: slice information, comprising: the S-NSSAI of the HPLMN, NSI ID of the HPLMN, S-NSSAI of the VPLMN, NSI ID of the VPLMN, etc., represent analysis information requesting a particular network slice.

Step 403, the H-NWDAF sends an analysis request to V-NWDAF1 in VPLMN1 according to the analysis request received in step 402, requesting V-NWDAF1 to provide analysis information for the roaming UE. The analysis request is substantially identical to the information contained in the analysis request of step 402, and does not contain a VPLMN ID.

Step 404-405, V-NWDAF1 sends a data collection request to the network function entity NF (e.g. V-AMF, V-SMF, V-UPF) and/or OAM of VPLMN1 according to the received analysis request, requesting the relevant data of the roaming UE movement or communication behaviour/state in VPLMN1, for obtaining the analysis information of the roaming UE.

The NF and/or OAM of VPLMN1 sends a data collection response or notification to the V-NWDAF according to the received data collection request, which contains the data information of the V-NWDAF request.

Specifically, the collected data may contain the following data/information of the roaming UE:

mobility characteristics: such as roaming UE location, movement pattern (movement trajectory, direction, speed, etc.), frequency of location update.

Communication characteristics: such as the traffic/application identity used by the roaming UE, the communication mode (duration, frequency of use, etc.).

Business/application features: such as the performance (e.g., traffic experience/quality of experience) of the traffic/applications of the roaming UE.

The access technology used. And, for a particular access technology, mobility, communication behavior/state, traffic/application performance information, etc. of the UE.

Step 406, the V-NWDAF1 performs data analysis according to the received data from the VPLMN1 NF and/or OAM to obtain analysis information of the roaming UE behavior/state in the VPLMN 1.

Specifically, the analysis information may include the following statistical and/or predictive information of roaming UE behavior/state:

Communication characteristics: such as the traffic/application identity, communication mode (duration, frequency of use) used by the roaming UE.

Business/application features: e.g., performance of traffic/applications (e.g., traffic experience Service Experience/QoE) of the roaming UE;

the access technology used. And, for a particular access technology, mobility, communication behavior/state, traffic/application performance information of the UE.

If the analysis request in step 401 includes UE location, region of interest, time period and/or slice information, the analysis information is analysis information of the behavior/state of the roaming UE in the UE location region, region of interest, time period and/or network slice in the VPLMN 1.

Step 407, V-NWDAF1 sends analysis information of roaming UE in VPLMN1 to H-NWDAF.

Step 408, the H-NWDAF sends analysis information of the roaming UE in VPLMN1 to the SOR AF.

Step 409, SOR AF determines the movement trend (e.g. predicted movement trajectory), communication requirements/traffic/application performance requirements of the UE based on the analysis information of the roaming UE in VPLMN 1.

The SoR AF further determines SoR information according to the UE's mobility tendency, communication requirements/traffic/application performance requirements, and VPLMN information configured or acquired locally (e.g. from UDM/NRF or using the method in example one), namely: an "operator controlled selected PLMN/access technology" list.

In this list, PLMN/access technologies are ranked from high to low in terms of degree of compliance/satisfaction with UE mobility trends, communication needs, services, application performance needs, etc., namely: the coverage service area can cover a moving track (moving area) of the roaming UE, and a PLMN/access technology capable of supporting communication requirements/traffic/application performance requirements of the roaming UE is used as a preferred PLMN/access technology. For example: VPLMN3/5G, VPLMN1/5G, VPLMN2/5G, VPLMN3/WiFi.

If the SoR AF has analysis information on the network/access technology of the VPLMN (see example one), the SoR AF may also combine: (1) the extent to which PLMN/access technology is in compliance/satisfaction with UE mobility trends, communication requirements, and/or traffic/application performance requirements. (2) Performance of network/access technology of PLMN. Thereby determining SoR information. For example:

(1) In the above list of "operator controlled selected PLMN/access technology", the PLMN/access technology capable of covering the moving track (moving area) of the roaming UE and meeting the communication requirement/service/application performance requirement is further arranged according to the performance of the PLMN/access technology from high to low.

(2) In the "operator controlled selected PLMN/access technology" list, comprehensive considerations are taken: the PLMN/access technology covers the mobile track (/ mobile area) of the roaming UE, the case of meeting the communication requirements/service/application performance requirements, and the performance of the PLMN/access technology, and the PLMN/access technology is ranked by priority from high to low.

Step 410, SOR AF provides SOR information to the UE. For example: the SOR AF notifies the AMF of SOR information through the UDM, and the AMF transmits the SOR information to the UE.

In step 411, the UE reselects the 5G cell of VPLMN3 according to the SoR information, and initiates registration to VPLMN 3.

Example four: UDM obtains analysis information of UE in PLMN

Still referring to fig. 4, the difference from example three is that in example four, in step 401, the UE registers with the roaming network VPLMN1; the SoR AF in example three is replaced by UDM in steps 402, 408 and 409; in step 410, the UDM provides SoR information to the UE. For example: the UDM notifies the AMF of the SoR information, and the AMF transmits the SoR information to the UE.
