Table, edge service application then carry out the transmission of business datum according to the routing table and terminal device.
Alternatively possible embodiment are as follows: it is current for terminal that edge service application can also use the mode of study to determine
Equipment provides the UPF entity of service.For example, when selecting a UPF entity, such as UPF in multiple UPF entities in edge network
Entity 1, and be after terminal device establishes the network connection of RAN to UPF entity 1, UPF entity 1 is then flat by EC connected to it
The business datum that terminal device is sent is sent to edge service application by platform 1, then edge service is applied is received by EC platform 1
The business datum of terminal device, then edge service application is determined currently then according to the connection relationship of UPF entity and EC platform
The UPF entity 1 of service is provided for terminal device.
In the embodiment of the present application, how EC platform 1 is not determined if limiting to edge service application.
It is moved to second area when terminal device moves, such as from first area, SMF entity is according to terminal device
Position is that terminal device has reselected a new UPF entity, such as UPF entity 2, at this point, SMF entity is built for terminal device
The network connection of vertical RAN to UPF entity 2, and the situation of change of UPF entity is sent to edge service application.Specifically, exist
The identification information of UPF1 entity and the identification information of UPF2 entity can be carried in the notification message, it is of course also possible to carry
Other information, this is not restricted.In the following description, by with include in the message UPF1 entity identification information and
It is illustrated for the identification information of UPF2 entity.
SMF entity can be to the situation of change that edge service application sends UPF entity and make an appointment, as long as with end
The UPF entity of end equipment connection changes, which is then sent to edge service application automatically by SMF entity；It can also
To be when edge service application has subscribed the notification message, which is just sent to edge service application by SMF entity,
In this case, the method in the embodiment of the present invention is before step 401 further include:
Step 402: the edge service is applied to the SMF entity and subscribes to the notification information.
When terminal device is mobile, edge service application can be obtained by subscribing to the notification message that UPF changes to SMF entity
Take the change of edge UPF entity.When the edge UPF entity connecting with terminal device changes, SMF entity then notifies edge
Service application.
In the specific implementation process, edge service, which is applied to send to SMF entity, subscribes to message, carry in the subscription message to
What SMF entity was subscribed to changes the parameters such as the change that notification event is UPF entity, as shown in Figure 5.
It should be noted that edge service is applied after sending the subscription message to SMF entity, edge service application can also
To cancel the subscription message according to the actual situation, for example, edge service application determines within a certain period of time, need to stop to service
When, in this case, edge service application can send to SMF entity and unsubscribe message, as shown in Figure 5.
By going the interface of subscription, Service Notification to open using the service subscription between SMF entity, service edge service
It puts, is conducive to interconnecting for the 5G network equipment and edge service application apparatus, respective evolution.
It should be noted that step 402 is optional step, that is, step 402 is not required execution.For example, SMF entity
In can pre-set, situation of change is sent to side automatically as long as the UPF entity connecting with terminal device changes
Edge service application, in this case, then step 402 can be without carrying out.
Step 403: the edge service is applied corresponding with the second edge UPF according to the determination of preset connection relationship
Edge calculations EC platform.
In embodiments of the present invention, the preset connection relationship is the edge UPF and EC platform of SMF entity control
Connection relationship.
After edge service application receives the notification message of SMF entity transmission, then according to carrying in the notification message
The identification information of two UPF entities determines that the UPF entity connecting with terminal device has been switched to UPF entity by UPF entity 1
2.Due to being previously stored with the connection relationship of each UPF entity and EC platform in edge service application, then edge service application root
Determine that the EC platform connecting with the UPF entity 2 is EC platform 2 according to the connection relationship.
Step 404: the edge service, which is applied, is sent to target EC platform for business datum, so that the terminal device is logical
It crosses the target EC platform and obtains the business datum, the target EC platform is the edge connecting with the second edge UPF
Calculate EC platform.
In a kind of possible embodiment, when edge service application determination is corresponding with the UPF entity 2 that terminal device connects
EC platform receives EC in edge service application for after EC platform 2, edge service application then sends registration request to EC platform 2
After the registration reply message that platform 2 is sent, the business datum for being sent to terminal device is sent to EC platform 2, so that terminal is set
It is standby then from EC platform 2 obtain the business datum.
It is applied due to edge service to EC platform 2 and sends registration request and EC platform 2 to edge service application transmission note
Volume response message is also required to certain waiting time, therefore, in order to better ensure that business continuance, before step 401, institute
State method further include:
Step 405: sending registration message to multiple EC platforms.
In embodiments of the present invention, step 405 the specific implementation process is as follows:
Each EC platform into multiple EC platforms of preset configuration sends service registration request；Wherein, the service note
Volume request sends the permission of business datum for obtaining by the EC platform to the terminal device, and the multiple EC platform includes
The source EC platform.
In the specific implementation process, the information of multiple EC platforms can be pre-configured in edge service application, such as multiple
It is infused according to the address of multiple EC platform from each EC of trend then after edge service application starts the address of EC platform
Volume, as shown in fig. 6, edge service is as follows using the process of any one EC platform registration into multiple EC platforms:
1) edge service is applied to the EC platform and sends service registration request；
2) after the EC platform receives service registration request, new service is registered；
3) the EC platform sends service registration response to edge service application.
In this way, when terminal device is moved to different EC platforms, local service service being capable of business number to terminal device
Received and dispatched according on different EC platforms, and be able to use terminal device it is mobile before EC1 and terminal device it is mobile after
All kinds of services provided by EC2, such as network capabilities open service, location-based service, radio network information service etc..
It should be noted that step 405 can execute before step 402, can also execute after step 402,
It can be performed simultaneously with step 402, this is not restricted, in Fig. 4 by taking step 405 executes after step 402 as an example.
It should be noted that can be carried out to multiple EC when edge service is applied without providing service to terminal device
It goes to register, as shown in Figure 7.By edge service using being illustrated for carrying out registration to first EC platform, this goes to register
Process it is as follows:
1) edge service is applied to first EC platform transmission service and removes registration request；
2) first EC platform receives after service removes registration request, goes to register registered service；
3) first EC platform sends service to edge service application and goes registration response.
It should be noted that step 405 is optional step, that is, it is not required execution.If being stored in edge service application
There is the information of multiple EC platforms, then step 405 has to carry out.
Further, since edge service application is to send business datum according to routing table, in edge service application
Stored routing table of the terminal device to EC platform 1, after the UPF entity connecting with terminal device is switched to UPF entity 2,
Edge service application need establish and storage terminal device to EC platform 2 routing table, therefore, in order to save edge service application
Memory space, the method in the embodiment of the present invention is before step 404 further include:
Step 406: routing iinformation corresponding with the terminal device is modified in the edge service application, and the routing is believed
Breath is revised as by the first routing iinformation of the terminal device to source EC platform by the terminal device to the target EC platform
Secondary route information, the source EC platform is the EC platform connecting with the first edge UPF entity.
After it is EC platform 2 that edge service is using the EC platform connecting with UPF entity 2 is determined, edge service application is then right
The terminal device of storage and the routing table of EC platform are updated, to establish path and deletion of the terminal device to EC platform 2
Terminal device, to only need to store a routing table in edge service application, saves edge to the path of EC platform 1
The memory space of service application.
It should be noted that step 406 is optional step, that is, be not required execution.
Correspondingly, the implementation procedure of step 403 are as follows: the edge service is applied will be described according to the secondary route information
