[0094] The uplink and downlink flows of the traditional service are symmetrically implemented, for example, the Internet Protocol (IP) and the port of the uplink and downlink flows are the same, and are symmetrically mapped. However, when the uplink and downlink flows represent the reporting time delay respectively, the network exposure function (NEF) cannot implement the binding of the uplink and downlink flows.

[0095] In the related art, for events involving secondary processing, the existing event subscription and reporting method cannot distinguish the binding relationship of different dimensions or different groups in the same event. For example, in the prior art, the time delay of an RTT event can be reported through two data streams, an uplink (UL) stream and a downlink (DL) stream. When the service consumer receives the service response after subscription, the binding relationship between the UL stream and the DL stream cannot be determined, and the uplink stream and the downlink stream related to the same RTT event cannot be distinguished, so the RTT cannot be calculated according to the time delay of the uplink stream and the time delay of the downlink stream of the same RTT event.

[0096] Based on this, in various embodiments of the present application, the first network function sends first information to the second network function, the first information indicating or identifying the uplink stream and / or the downlink stream and / or the media information and / or the second information related or associated with the first event requested to be subscribed; the second network function receives the first information sent by the first network function, and sends at least one third information to the first network function, the third information including the time delay and the first information, the time delay including the time delay of the uplink stream and / or the time delay of the downlink stream. It can be seen that in the embodiments of the present application, since the third information sent by the second network function to the first network function includes the first information, and the first information indicates or identifies the uplink stream and / or the downlink stream and / or the media information and / or the second information related or associated with the first event requested to be subscribed, the first network function can identify the uplink stream and the downlink stream related to the same first event according to the first information, and thus calculate the RTT of the first event.

[0097] The present application will be described in further detail below with reference to the accompanying drawings and embodiments.

[0098] The embodiments of the present application provide a data processing method applied to a first network function, which can be a subscriber or service consumer (consumer) of a first event, including an application function (AF) and / or a network exposure function (NEF); the first network function can also be an intermediate node forwarding a subscription request related to the first event, including one or more of the following: an access and mobility management function (AMF), a policy control function (PCF), and a session management function (SMF). As shown in FIG. 1, the method includes:

[0099] Step 101: sending first information to the second network function.

[0100] The first information indicates or identifies the first event related or associated uplink and / or downlink and / or media information and / or second information that is requested to be subscribed.

[0101] Here, the first network function can send the first information to the second network function directly, or send the first information to the second network function through an intermediate node, which includes AMF and / or PCF and / or SMF. The first information can show or implicitly indicate the first event related or associated uplink and / or downlink and / or media information and / or second information that is requested to be subscribed. The explicit indication manner can be that the content of the first information includes the first event related or associated uplink and / or downlink and / or media information and / or second information. The implicit indication manner can be that a specific identifier is carried in the first event, or a specific identifier and / or second information is carried in the first event related uplink and / or downlink and / or media information. The specific identifier can be described as a set identifier, which can include one or more of notification identifier, URI, association identifier, and correlation identifier.

[0102] In actual application, the first network function can send the first information to the second network function in the process of subscribing to the first event. For example, the first network function sends a subscription request to the second network function, and the subscription request carries at least the first event and the first information, and can also carry attribute information of the uplink and downlink of the first event; the uplink and downlink can be referred to as uplink and downlink, and the attribute information of the uplink can include media information related to the uplink, and the attribute information of the downlink can include media information related to the downlink. The subscription request is used to request to subscribe to the first event, and the first event includes an RTT event, which represents a request to measure the RTT, or represents to measure the delay of the uplink and downlink. The subscription request can be described as registration request information (EventsSubscReqData).

[0103] The first network function can obtain the first relationship, and can also obtain the second relationship and / or the third relationship, which can be determined by the first network function or preconfigured. The first relationship at least includes the correspondence between the first event and the corresponding uplink and downlink; the second relationship includes the correspondence between the uplink and the media information, and / or the correspondence between the downlink and the media flow; and the third relationship at least includes the correspondence between the first event and the second information. The second information can be used to indicate different dimensions and / or different groups of uplink and downlink related or associated with the first event.

[0104] The second network function can be understood as a network function for measuring latency, and the second network function includes a user plane function (UPF, User Plane Function).

[0105] The media information can be understood as media information corresponding to the RTT flow, including media information corresponding to the first event related uplink flow and / or media information corresponding to the first event related downlink flow. The media information corresponding to the first event related uplink flow and downlink flow respectively can be the same or different; that is, the first event related uplink flow and downlink flow can be defined in different media information. The media information includes a media component and a media subcomponent (MediaSubComponet).

[0106] In order to facilitate the first network function to bind the uplink flow and the downlink flow of the same RTT event to calculate the RTT, in an embodiment, the first information includes one or more of the following:

[0107] The notification identifier or URI of the first event related uplink flow;

[0116] The second information associated with the first event;

[0117] The URI and / or relevance identifier and / or correlation identifier and / or association identifier of the second information associated with the first event.

[0118] Here, the notification identifier can be described as notify Identifier, and Identifier can be abbreviated as ID; the URI can be described as notify URI (notification URI) or notifUri.

[0119] The correlation identifier can be described as correlation ID, and the association identifier can be described as association ID. The association identifier or correlation identifier or association identifier of the first event can be described as RTT binding relationship ID, RTT association relationship ID, or RTT association marker, or RTT correlation ID, notif correlation ID, or notifCorreId. The RTT association marker is used to indicate that the RTT measurement corresponds to the uplink and downlink flow.

[0120] It should be noted that in the embodiments of the present application, the association identifier, the correlation identifier, and the association identifier can be used equivalently or interchangeably.

[0121] In an embodiment, the second information includes one or more of the following:

[0122] Flow information;

[0123] Position information;

[0124] User information;

[0125] Time information.

[0126] Here, the flow information can be a flow number or a flow number (flow number), and the user information can include one or more of the following: generic public user identifier (GPSI, Generic Public Subscription Identifier), international mobile subscriber identity (IMSI, International Mobile Subscriber Identity), generic public user identifier (GPSI, Generic Public Subscription Identifier). The second information can also include a media number (media number).

[0127] In this embodiment, the uplink and downlink flow related to the first event can be divided into dimensions or grouped according to the second information, for example, the uplink and downlink flow is divided according to the position information and / or time information, and the uplink and downlink flow is grouped according to the flow information and / or user information, that is, the second information can be used to indicate different dimensions and / or different groups of uplink and downlink flow related or associated with the first event, and therefore, the first network function can determine the RTT according to different dimensions or different groups for the first event, so as to improve the statistical efficiency of the RTT.

[0128] In order to facilitate the first network function to bind the uplink and downlink of the same RTT event to calculate the RTT, in an embodiment, the notification identities of the uplink and downlink related to the first event are the same or form a binding or association relationship; and / or,

[0129] The URIs of the uplink and downlink related to the first event are the same or form a binding or association relationship; and / or

[0130] The correlation identities of the uplink and downlink related to the first event are the same or form a binding or association relationship; and / or,

[0131] The association identities of the uplink and downlink related to the first event are the same or form a binding or association relationship; and / or,

[0132] The correlation identities of the uplink and downlink related to the first event are the same or form a binding or association relationship; and / or

[0133] The notification identities carried by the media information associated with the uplink related to the first event are the same as or form a binding or association relationship with the notification identities carried by the media information associated with the downlink corresponding to the first event; and / or

[0134] The URIs carried by the media information associated with the uplink related to the first event are the same as or form a binding or association relationship with the URIs carried by the media information associated with the downlink corresponding to the first event; and / or

[0135] The correlation identities carried by the media information associated with the uplink related to the first event are the same as or form a binding or association relationship with the correlation identities carried by the media information associated with the downlink corresponding to the first event; and / or

[0136] The association identities carried by the media information associated with the uplink related to the first event are the same as or form a binding or association relationship with the association identities carried by the media information associated with the downlink corresponding to the first event; and / or

[0137] The correlation identities carried by the media information associated with the uplink related to the first event are the same as or form a binding or association relationship with the correlation identities carried by the media information associated with the downlink corresponding to the first event.

[0138] Here, forming a binding or association relationship can be understood as forming a binding relationship or an association relationship.

[0139] To facilitate the first network function to bind the uplink and downlink of the same RTT event for calculating the RTT, on the basis that the first information comprises the URI and / or the correlation ID and / or the relevance ID and / or the association ID of the second information associated with the first event, the second information configuration URI and / or the correlation ID and / or the relevance ID and / or the association ID needs to be configured before the first information is sent to the second network function. Based on this, in an embodiment, the method further comprises:

[0140] configuring the second information configuration URI and / or the correlation ID and / or the relevance ID and / or the association ID associated with the first event.

[0141] To improve the efficiency of determining the RTT, the RTT can be calculated by dimension or group. Based on this, in an embodiment, the second information configuration URI and / or the correlation ID and / or the relevance ID and / or the association ID associated with the first event comprises:

[0142] configuring different URI and / or different correlation ID and / or different relevance ID and / or different association ID for the second information of different dimensions and / or different groups associated with the first event; and / or,

[0143] configuring different or same URI and / or different or same correlation ID and / or different or same relevance ID and / or different or same association ID for the second information of same dimensions and / or same groups associated with the first event.

[0144] Here, in the case that the uplink and downlink related to the first event can be divided by dimension or grouped according to the second information, the first network function can configure different notify URI and / or different correlation ID and / or different association ID for the uplink and downlink of different dimensions or different groups, and configure different or same notify URI and / or different or same correlation ID and / or different or same association ID for the uplink and downlink of same dimensions or same groups. The correlation ID can be understood as the correlation ID or the relevance ID.

[0145] For example, different URI and / or different correlation ID and / or different relevance ID and / or different association ID are configured for different flow information associated with the first event, and same URI and / or same correlation ID and / or same relevance ID and / or same association ID are configured for the same flow information associated with the first event.

[0146] For example, different location information or user group associated with the first event is configured with different URI and / or different association identifier and / or different relevance identifier and / or different association identifier, and same location information or user group associated with the first event is configured with same URI and / or same association identifier and / or same relevance identifier and / or same association identifier.

[0147] For example, different user information associated with the first event is configured with different URI and / or different association identifier and / or different relevance identifier and / or different association identifier, and same user information associated with the first event is configured with same URI and / or same association identifier and / or same relevance identifier and / or same association identifier.

[0148] For example, different time information associated with the first event is configured with different URI and / or different association identifier and / or different relevance identifier and / or different association identifier, and same time information associated with the first event is configured with same URI and / or same association identifier and / or same relevance identifier and / or same association identifier.

[0149] In consideration of some uplink and downlink streams are defined in media information, the uplink and downlink streams can be defined in different media information, in order to facilitate the calculation of RTT, in an embodiment, the first information is carried in the media information related to the first event, the first information carried in the different media information related to the first event is same or forms a binding or association relationship.

[0150] Here, in the case that the uplink and downlink streams of the first event are related to the media information, for example, the uplink and downlink streams that need to be measured are defined in different media information, the first information is carried in the media information related to the first event, and the first information carried in the different media information related to the first event is same or forms a binding or association relationship. If the media information contains the first event or the uplink and downlink streams related to the first event, it can be considered that the media information is related to the first event.

[0151] In actual application, in the process of subscribing the first event, the first network function can carry the fixed or set notifUri and / or notifCorreId in each media information related to the first event. For example, in the process of subscribing the first event: the first network function carries the same notifUri and / or notifCorreId in each MediaSubComponet corresponding to the RTT flow to be monitored; if two media information carries a set of uplink and downlink flows related to the RTT event, the first network function realizes the binding of the same RTT event by setting the same notifUri and / or notifCorreId. The RTT flow can be understood as the uplink and downlink flows related to the RTT event, or the uplink and downlink flows to be measured for RTT.

[0152] In an embodiment, after sending the first information to the second network function, the method further comprises:

[0153] receiving at least one third information sent by the second network function, the third information comprising the time delay and the first information, the time delay comprising the time delay of the uplink flow and / or the time delay of the downlink flow.

[0154] Here, the second network function directly or indirectly sends the third information to the first network function in the case of measuring the time delay of the uplink and downlink flows of the first event; the time delay in the third information can be in one-to-one relationship with the first information, or in many-to-one relationship with the first information; for example, in the case that the first information comprises the association identifier or the correlation identifier or the association identifier of the first event, the time delay in the third information is in many-to-one relationship with the first information; in the case that the first information does not comprise the association identifier or the correlation identifier or the association identifier of the first event, the time delay in the third information is in one-to-one relationship with the first information. The second network function can inform the time delay of one uplink flow or the time delay of one downlink flow through one third information, for example, the third information is a notification message (notification or EventsNotification); the second network function can also inform the time delay of one uplink flow and the time delay of one downlink flow through one third information, or inform the time delay of multiple uplink flows and / or the time delay of multiple downlink flows through one third information, for example, the third information is an RTT report (rttMonReports).

[0155] It should be noted that the first network function can be a subscriber of the first event, or an intermediate node forwarding the subscription request related to the first event, and the intermediate node comprises a PCF and / or an AMF and / or an SMF.

[0156] In order to obtain accurate RTT, in an embodiment, the method further comprises one or more of the following:

[0157] binding or associating the first event and corresponding uplink and downlink according to the first information comprised in the third information;

[0158] binding or associating the first event and corresponding third information according to the first information comprised in the third information;

[0159] binding or associating the first event and corresponding second information according to the first information comprised in the third information;

[0160] determining the RTT corresponding to the first event according to the third information.

[0161] Here, since the first information indicates or identifies the uplink and / or downlink and / or media information and / or second information related or associated with the first event for which the subscription is requested, the first network function, upon receiving the third information, can determine the uplink and downlink related to the same first event according to the first information comprised in the third information, and bind or associate the first event and corresponding uplink and downlink; can also bind or associate the first event and corresponding second information according to the second information related to the first event indicated by the first information comprised in the third information; and can also determine the first event related to the third information according to the first information comprised in the third information in the case where the third information comprises a time delay, and bind or associate the first event and corresponding third information.

[0162] The first network function can determine the uplink and / or downlink and / or media information and / or second information related or associated with the first event according to the notification identifier and / or URI and / or association identifier and / or relevance identifier and / or association identifier and / or second information comprised in the first information, and bind or associate the first event and corresponding uplink and downlink, and / or bind or associate the first event and / or corresponding second information and / or third information. For example, the uplink and downlink with the same notification identifier and / or URI and / or association identifier and / or relevance identifier and / or association identifier are determined, and the determined uplink and downlink are bound or associated with the first event. For another example, the media information with the same notification identifier and / or URI and / or association identifier and / or relevance identifier and / or association identifier is determined, and the uplink and downlink related to the determined media information are bound or associated with the first event related to the media information. For another example, the second information with the same notification identifier and / or URI and / or association identifier and / or relevance identifier and / or association identifier is determined, and the determined second information is bound or associated with the first event related to the second information, and the determined second information can also be bound or associated with the uplink and downlink related to the second information, and the first event related to the second information and the uplink and downlink related to the second information are further bound.

[0163] The first network function can determine the RTT corresponding to the first event in any of the following manners:

[0164] Manner one: according to the first information included in the third information, a set of uplink flows and downlink flows related to the first event is determined, and the time delays of the set of uplink flows and the set of downlink flows related to the first event are accumulated or summed to obtain the RTT corresponding to the first event.

[0165] Manner two: if according to the third information, it is determined that the notification identifier and / or URI and / or association identifier and / or correlation identifier and / or association identifier and / or second information indicated by the first information corresponding to any two time delays are the same or have a binding relationship or an association relationship, it is represented that the two time delays are respectively the time delay of the uplink flow and the time delay of the downlink flow of the same first event, then the first network function accumulates the two time delays to obtain the RTT of the first event.

[0166] Manner three: in the case of binding or associating the first event and the corresponding uplink flow and downlink flow, the time delay of the uplink flow related to the first event and the time delay of the downlink flow related to the first event can be determined in the third information, and the time delays of the set of uplink flows and the set of downlink flows related to the first event are accumulated or summed to obtain the RTT corresponding to the first event.

[0167] Manner four: in the case of binding or associating the first event and the corresponding third information, the time delays contained in the third information bound with the first event are accumulated or summed to obtain the RTT of the first event.

[0168] Manner five: in the case of binding or associating the first event and the corresponding second information, according to the correspondence between the second information and the uplink flow and / or the downlink flow, a set of uplink flows and downlink flows related to the first event is determined, and the time delays of the set of uplink flows and the set of downlink flows related to the first event are accumulated or summed to obtain the RTT corresponding to the first event.

[0169] The subscriber (such as AF and / or NEF) or intermediate node (such as AMF and / or SMF) of the first event can both determine the RTT to fully utilize the resources and improve the flexibility of calculating the RTT. Based on this, in an embodiment, the determining the RTT corresponding to the first event according to the third information comprises:

[0170] determining the third information corresponding to the first event according to the first information included in the third information;

[0171] determining the RTT according to the time delay included in the third information corresponding to the first event.

[0172] Here, the first network function can determine the uplink delay and the downlink delay related to the first event according to the first information included in the third information, i.e., determine the set of uplink and downlink delays related to the first event; and accumulate or sum the uplink delay and the downlink delay related to the first event to obtain the RTT of the first event. Specifically, in the case that the notification identifier and / or URI and / or association identifier and / or relevance identifier and / or correlation identifier and / or second information indicated by the first information corresponding to any two delays are the same or have a binding relationship or an association relationship, it is indicated that the two delays are respectively the uplink delay and the downlink delay of the same first event.

[0173] In the case that one uplink delay and one downlink delay are included in the third information, and the first information associated with the two delays is the same, the uplink delay and the downlink delay included in the third information are accumulated to obtain the RTT of the first event.

[0174] In the case that two or more third information are received, and one uplink delay or one downlink delay is included in one third information, since the first information is used to indicate the uplink and / or downlink and / or media information and / or second information related to the first event, the third information corresponding to the first event can be determined according to the first information included in the third information, and the RTT of the first event can be determined according to the delay included in the third information corresponding to the first event. For example, whether different third information belong to the same first event can be determined according to the notification identifier and / or URI and / or association identifier and / or relevance identifier and / or correlation identifier and / or second information indicated by the first information included in the third information; in the case that the notification identifier and / or URI and / or association identifier and / or relevance identifier and / or correlation identifier and / or second information indicated by the first information included in different third information are the same or have a binding relationship or an association relationship, the different third information belong to the same first event, so that a set of third information corresponding to the first event can be obtained, and the delays included in the set of third information corresponding to the first event are accumulated to obtain the RTT of the first event.

[0175] In a case that a third information is received, and the third information includes a plurality of uplink time delays and a plurality of downlink time delays, each time delay corresponds to a first information, if the notification identifiers and / or URIs and / or association identifiers and / or correlation identifiers and / or association identifiers and / or second information indicated by the first information corresponding to any two time delays are same or form a binding relationship or an association relationship, it is represented that the two time delays are respectively an uplink time delay and a downlink time delay of a same first event, and then the first network function adds the two time delays to obtain the RTT of the first event. Alternatively, the first network function can also determine the uplink time delay and the downlink time delay related to the same first event according to the first information corresponding to each time delay, and add the uplink time delay and the downlink time delay related to the same first event to obtain the RTT of the first event. The uplink stream and the downlink stream related to the same first event satisfy one or more of the following conditions:

[0176] The notification identifiers of the uplink stream and the downlink stream related to the same first event are same or form a binding or association relationship.

[0177] The URIs of the uplink stream and the downlink stream related to the same first event are same or form a binding or association relationship.

[0180] The association identifiers of the uplink stream and the downlink stream related to the same first event are same or form a binding or association relationship.

[0181] The notification identifiers carried by the media information associated with the uplink stream related to the first event are same or form a binding or association relationship with the notification identifiers carried by the media information associated with the downlink stream corresponding to the first event.

[0182] The URIs carried by the media information associated with the uplink stream related to the first event are same or form a binding or association relationship with the URIs carried by the media information associated with the downlink stream corresponding to the first event.

[0183] The correlation identifiers carried by the media information associated with the uplink stream related to the first event are same or form a binding or association relationship with the correlation identifiers carried by the media information associated with the downlink stream corresponding to the first event.

[0184] The association identifiers carried by the media information associated with the uplink stream related to the first event are same or form a binding or association relationship with the association identifiers carried by the media information associated with the downlink stream corresponding to the first event.

[0185] The association identifier carried by the media information of the uplink stream related to the first event is the same as or forms a binding or association relationship with the association identifier carried by the media information of the downlink stream corresponding to the first event.

[0186] The second information related to the uplink stream related to the first event is the same as or forms a binding or association relationship with the second information related to the downlink stream related to the first event.

[0187] The URI of the second information related to the uplink stream related to the first event is the same as or forms a binding or association relationship with the URI of the second information related to the downlink stream related to the first event.
