In the embodiment of the application, the ECS option can search NEF (local NEF) in the DNS query, so as to improve the working performance of the communication device.

The information transmission method provided in the embodiments of the present application is illustrated by a plurality of embodiments, in which the first information includes ECS address configuration information:

example 1:

in this embodiment, in order to send ECS address configuration information to a single terminal, and each ECS address configuration information is different, the main difference is who provides the information, which application in the terminal the information is sent to, and so on, as shown in fig. 9, specifically, the method includes the following steps:

step 0: the NF sends an SDM subscription request to the UDM to subscribe to the service of the UDM, and in this embodiment, the NF (e.g., SMF) subscribes to an update of terminal subscription data in the UDM, or an update of a set of terminal subscription data.

For example: the SMF subscribes to the UDM for UE subscription data including session management subscription data (Session Management Subscription data) including ECS address configuration information.

Step 0b: AF subscribes to or receives terminal mobility analysis and/or terminal communication analysis information from NWDAF;

Step 0c: the AF verifies the received data and derives predicted terminal behaviour and/or parameters.

Step 1, AF sends a parameter providing Create/Update/Delete request (nnef_parameter provision_create or nnef_parameter provision_update or nnef_parameter provision_delete) to NEF. The parameters generated, updated and deleted here are ECS address configuration information, and the parameters may specifically include:

ECS address: the address of the ECS comprises the IP address of the ECS and FQDN;

ECS ID: for identifying which ECS is;

ECSP ID: an ECS address for identifying who is provided;

APP ID: for identifying to which application in the terminal this ECS address is addressed;

EEC ID: for identifying to which EEC in the terminal this ECS address is addressed;

AC ID: for identifying to which client in the terminal this ECS address is addressed.

The relationship can be represented by the following table:

table 1:

ECS address configuration information	Description of the invention
		ECS address	Fqdn and/or ECS IP address
ECS ID	For identifying ECS, the terminal uses this information to distinguish ECS
		ECSP ID	Provider for identifying ECS
APP ID	For identifying applications
		AC ID	For identifying clients
EEC ID	For identifying EECs

Step 2: the NEF trigger parameters provide a create/update/delete request, which, like step 1, includes at least parameters for providing to the UDM to update, create or delete parameters. The included parameters may specifically include:

ECS ID: for identifying which ECS is;

ECSP ID: an ECS address for identifying who is provided;

Step 3: the UDM sends a Query instruction (nudr_dm_query) to the UDR to verify the required data updates and authorize the changes for the subscriber or group of the corresponding AF.

Wherein a Data set identification (Data Set Identifier), a Data Key(s), is provided for the case where ECS address configuration information in the UDR is to be queried.

Wherein data set Identifier is: session management subscription (ECS address configuration information is contained in this data set)

The Data key is: a user permanent identity (Subscription Permanent Identifier, SUPI); SUPI is used to determine which terminal subscription data change

The UDM, like the UDR, stores terminal subscription data (subscription data includes session management subscription data, and ECS address configuration information is also in the session management subscription data);

Since other matching information than the ECS address, such as ECS ID, ECSP ID, etc., is newly added, a plurality of ECS addresses may exist for the same terminal, each address corresponding to different matching information, and thus a plurality of ECS addresses may be distinguished.

Step 4: the UDM triggers a data Update operation (Nudr_DM_update service) to Update ECS address configuration information in the UDR;

wherein Data Set Identifier, data Key(s) is provided for the case of ECS address configuration information in the UDR to be updated.

Step 5, step 6: the UDM informs the NEF that the current parameter update, creation or deletion is successful, or fails, and the NEF informs the AF.

Step 7: the UDM sends a nudm_sdm_notification to the subscriber to notify that the parameters have been updated. In this embodiment, the subscription to the UDM service is an SMF network element.

The SMF may then send the changed ECS address configuration information to the terminal based on the SUPI. The terminal sends the matching information of each ECS address to the corresponding application according to the ECS address configuration information; at the same time, the UE can also identify which ECS address was provided by who.

Example 2:

in this embodiment, the multi-ECS address is sent to the UE, and the UE sends to a specific application for illustration, as shown in fig. 10, including the following steps:

Step 1: the SMF sends ECS address configuration information to the UE through an ePCO process.

Step 2: after the UE obtains the ECS address configuration information, the ECS address configuration information in the UE may be saved or updated. The UE maintains ECS address configuration information and notes which APP, EEC, AC the information can be used for and which provider the ECS is provided by (i.e., ECSP).

The UE has the capability to configure the ECS address (IP address or FQDN) according to the target object in the ECS address configuration information, for example: APP, EEC ID, AC ID, etc., forwards the ECS address to the corresponding application layer APP, client, or EEC.

This design method can distinguish a plurality of ECS addresses provided by a plurality of AFs into: which target objects are addressed and who provides the ECS address.

Example 3:

in this embodiment, the ECS addresses are issued in batches by using service parameters for illustration, as shown in fig. 11, including the following steps:

in step 0, step 0a is a group, step 0b+0c is a group, and step 0d+0e is a group, specifically as follows:

step 0a: a policy association is established between the AMF and the PCF.

Step 0b: SMF subscribes to events of UDM (Nudm_SDM_Subscribe). In this embodiment, the SMF subscribes to session management subscription data in the UE subscription data in the UDM, where the data includes ECS address configuration information.

Step 0c: the UDM subscribes to the services of the UDR (Nudr_DM_Subscribe). The UDR includes the following:

subscribed content 1:

the session management subscription data subset in the subscription data set comprises ECS address configuration information;

subscribed content 2:

the service specific information data subset ECS address configuration information in the data set is applied.

Step 0d: the event that the SMF subscribes to the PCF may specifically be an SM policy management update notification subscription (npcf_smpolicy control_updatenotify_subscribe). After the policy corresponding to the PDU session changes, or after the PCC policy changes, the PCF informs the SMF of the change.

Step 0e: the PCF subscribes to the event (Nudr_DM_Subscribe) of the UDR. The PCF subscribes to changes in information in the UDR, including AF service parameter set information (AF service parameter provisioning information)

Subscribed content:

Step 1: the AF generates an AF request, which in this example generates a request to change ECS address configuration information based on the data flow.

Step 2: AF triggers service parameter creation/Update/deletion (Nnef_ServiceParameter_Create, nnef_ServiceParameter_Update or Nnef_ServiceParameter_Delete) signaling, including at least one parameter of:

Service subscription;

ECS address association information;

ECS address configuration information;

service parameters;

wherein the service subscription includes at least one of:

combination of DNN and S-NSSAI, AF service identifier or application identifier

The combination of DNN and S-NSSAI described above may be DNN+S-NSSAI for a particular edge.

In one embodiment, the ECS Address association information may be included in a service subscription or may be included in ECS Address configuration information, where parameters of the service parameter creation/update/deletion signaling include: the service subscription (including matching information), the service parameter is ECS Address association information, which may also be called matching information, or binding information. The association information may send ECS address configuration information to the UE that matches the particular traffic data stream being described. Whenever those UEs meet this data flow description (e.g., as long as they access a particular game server), they all obtain ECS address configuration information. The ECS address configuration information may be referred to in the corresponding description of the embodiment shown in fig. 2.

In one embodiment, the ECS address configuration information may be included within the service parameters. Stated another way, the lower bits of the service parameters include: ECS address configuration information.

Step 3: the NEF stores the information in the AF request in the UDR in the form of application data. The service parameters (including ECS address configuration information) or ECS address configuration information, or matching information of ECS address configuration information n, are also stored in the UDR, and the subset of data is specific service information.

Examples of data storage are shown in the following table:

table 2:

wherein the specific service information includes:

ECS address configuration information;

matching information of ECS address configuration information.

The two information are a pair of mappings:

mapping of description information of a certain flow with ECS address configuration information.

Step 4: the NEF replies with an AF response, success or failure response.

Step 5a and step 5b are a pair; step 5c and step 5d are a pair;

step 5a: the UDR informs the PCF of new specific service information. At the same time, the relevant information of the ECS address configuration information is also sent to the PCF. The PCF then knows which UEs associated with this data flow should be addressed.

Step 5b: the PCF informs the SMF that the related strategy of the session is changed, and the SMF obtains the associated information of the ECS address configuration information and the ECS address configuration information matched with the data flow, so that all the UE which accords with the description of the data flow in the session can send the ECS address configuration information.

Step 5c: the UDR triggers Nudr_DM_notify to Notify the change of a specific service information subset (or the change of ECS address configuration information in the specific service information subset) in the subscription data set subscribed by the UDM; alternatively, the UDM is notified that a particular subset of service information in the subscribed application data set has changed (or, alternatively, that ECS address configuration information therein has changed). The UDM then receives the latest ECS address configuration information.

Step 5d: the UDM informs the SMF that the information described in step 5c has changed. The SMF obtains ECS address configuration information.

Step 6a: the PCF mass-transmits (UE policy deliver) specific service information (mainly ECS address configuration information) to a group of UEs in a terminal policy delivery manner. The group of UEs all have data streams matching the matching information, for example, a group of UEs are accessing an edge server of a game (for example, IP address: 10.1.1.1).

Step 6b: after the SMF receives the ECS address configuration information, the associated information is also obtained, the UE with the data flow meeting the requirements is found according to the associated information, and then the SMF issues the ECS address configuration information to the UE meeting the requirements, and an ePCO process is adopted. This procedure is a procedure of transmitting ECS address configuration information to a plurality of UEs, not a single UE.

Example 4:

the flow influencing (traffic influence) method is mainly described in this embodiment, as shown in fig. 12, and includes the steps of:

step 1: AF decides the flow-based mode, providing ECS address configuration information;

step 2: AF triggering: stream effect creation/Update/deletion (Nnef trafficinfiunce_create or Nnef trafficinfiunce_update or Nnef trafficinfiunce_delete);

the signaling, add at least one of the following:

association information of ECS address configuration information; this part is identical to that described in the third embodiment.

ECS address configuration information. This part is the same as in example 1 above.

Here, by providing some data to the data stream, those UEs that can match the data stream can be mass-sent with ECS address configuration information

Step 3: for flow effect creation/Update (nnef_trafficinfiuence_create_create or Update), NEF saves information in the request for AF in UDR, wherein the application function AF flow effect request information in the saved application data set is data subset, wherein the data key comprises at least one of the following:

AF business internal label (AF Transaction Internal ID)

S-NSSAI and DNN;

an internal packet identifier;

SUPI。

step 4: the PCF has subscribed to an AF request, see description of the application function AF flow influencing request information data subset in the application data set above.

Since the ECS address configuration information is newly provided, the PCF receives a notification from the UDR: nudr_DM_notify

Step 5: the PCF decides that the current existing PDU session will be affected by the AF request. Thus, the PCF sends the updated PCC rule to the SMF: npcf_smpolicycontrol_updatenotify

The ECS address configuration information is added to the policy and charging rules in the PCC rules, for example: the ECS address configuration information is added to the flow distribution control execution information (AF influenced Traffic Steering Enforcement Control) of the flow affected by the AF.

In another embodiment, the ECS address configuration information is directly added to the PCC rule.

Step 6: after the SMF receives the new PCC rule, the SMF performs as follows:

the SMF finds all the UE matched with the data flow in the PDU session according to the flow information provided by the AF;

then, SMF sends ECS address configuration information to all the UE;

and the UE sends the ECS address configuration information to each application or client of the corresponding UE according to the matching information.

In one embodiment, the description information of the flow provided by the AF includes an IP five-tuple, and the source IP is the IP address of the corresponding UE, so that the SMF can find the corresponding UE by itself.

The procedure described in step 6 is the same as in example 2.

Example 5:

the method for obtaining the FQDN is mainly described in this embodiment, where the FQDN may be obtained from the SMF or the EASDF.

Method 1: FQDN is obtained by EASDF. The UE IP in a certain flow to be affected and the destination IP are respectively from AF to NEF to UDR to PCF to SMF; so, after the SMF takes the flow screening information, it sends this information to the EASDF, from which it can look up the DNS contexts. Specifically as shown in fig. 13, the method comprises the following steps;

and step 1, AF generates an AF request.

Step 2, the AF sends a flow effect create/update/delete message to the NEF.

Step 3, UDR, EASDF and NEF store/update/remove information.

Step 4, NEF influences the creation/update/deletion response to AF flow.

And 5, the UDR sends a DM notification to the PCF.

And 6, the PCF sends an SM policy update notification to the SMF.

Step 7, SMF and UPF execute user plane reconfiguration.

And 8, the SMF sends a DNS context update request to the EASDF. The request is used to obtain the FQDN of the corresponding effect due to the flow effect

Step 9, the EASDF returns a DNS context update response to the SMF. The response sends the affected FQDN

Step 10, the SMF sends a NAS indication to the UE.

Method 2: the FQDN is obtained by the SMF or, since the EASDF sends the DNS FQDN and EAS IP to the SMF each time, this part of the content should also be kept in the SMF, so the SMF can also query the FQDN when the AF sends the flow effect to the SMF. As shown in detail at 14, comprising the steps of;

And step 1, AF generates an AF request.

Step 2, the AF sends a flow effect create/update/delete message to the NEF.

Step 3, UDR, EASDF and NEF store/update/remove information.

Step 4, NEF influences the creation/update/deletion response to AF flow.

And 5, the UDR sends a DM notification to the PCF.

And 6, the PCF sends an SM policy update notification to the SMF.

And 7, screening FQDN by SMF.

Step 8, SMF and UPF execute user plane reconfiguration.

Step 9, the SMF sends NAS indication to the UE.

Method 3: the flow screening of AF directly provides FQDN. As shown in detail at 15, comprising the steps of;

and step 1, AF generates an AF request.

Step 2, the AF sends a flow effect create/update/delete message to the NEF.

Step 3, UDR, EASDF and NEF store/update/remove information.

Step 4, NEF influences the creation/update/deletion response to AF flow.

And 5, the UDR sends a DM notification to the PCF.

And 6, the PCF sends an SM policy update notification to the SMF.

Step 7, SMF and UPF execute user plane reconfiguration.

And 8, the SMF sends NAS indication to the UE.

Method 4: FQDN is obtained through UPF detection and reporting. In the case that the UL CL has been inserted, the SMF configures a traffic rule for the UL CL and forwards it to the L-PSA if DNS query + route to local DN. The L-PSA detects the packet of the DNS inquiry and the DNS response, and then sends the packet to the SMF for recording; or the UL CL detects the packet of DNS query and DNS response and then sends it to the SMF. Thus, after the content affected by the flow sent by the AF reaches the SMF, the FQDN can be found. As shown in detail at 16, comprises the following steps;

Step 0, establishing PDU session.

Step 1, UL CL/BP insertion.

Step 2, AMF sends PDU session modification command to UE.

And step 3, the UE returns to PDU session modification completion.

And 4, issuing a detection rule.

And step 5, the UE transmits DNS inquiry.

And 6, the UL CL/BP reports the FQDN to the SMF.

And 7, forwarding and processing the DNS message.

Step 8, the L-PSA returns a DNS response.
