Wherein, which can be the UE 108 in Fig. 2, which can be the clothes of the MEC in Fig. 2
Business device 110.
Illustratively, shown in Fig. 2 for network architecture schematic diagram, UE 108 and MEC server 110 establish second
PDU session, when UE 108 is not in the service range of MEC server 110, SMF sends session establishment to MEC server 111 and asks
Information is sought, session establishment solicited message instruction MEC server 111 and UE 108 establish the first PDU session.
Optionally, user equipment and other MEC servers establish the 2nd PDU session, comprising: user equipment is to provider domain
Name system (Domain Name System, DNS) server sends the first query information nslookup, other MEC servers exist
User equipment intercepts and captures first query information into the way of carrier server the first query information of transmission, and according to the first inquiry
Information judges whether other MEC servers can provide service for user equipment, if other MEC servers can be user
Equipment provides service, then other MEC servers and user equipment establish the 2nd PDU session.
It should be noted that the process that the 2nd PDU session is established in user equipment and other MEC services can refer to following figures
The third of method shown in 3 realizes the description in scene.
Optionally, SMF entity sends session establishment solicited message to MEC server, comprising: SMF entity is to MEC server
UPF send session establishment solicited message.
Illustratively, shown in Fig. 2 for network architecture schematic diagram, SMF 107 can be to the UPF in MEC server 111
111a sends session establishment solicited message.
A kind of possible implementation, SMF entity is according to the load of the location information and/or MEC server of MEC server
Information determines MEC server.
For example, SMF entity can determine that the MEC server nearest from user equipment is the MEC server, alternatively, SMF is real
Body can determine that loading small MEC server is the MEC server.
Alternatively possible implementation, SMF entity also according to UPF deployment types and/or PDU conversation type, and/
Or user equipment subscription information determines MEC server.
Wherein, the deployment types of UPF may include disposing in distributed deployment sum aggregate.

The conversation type of two PDU sessions.
It should be noted that step 304, which can be equivalent to, establishes core net industry for MEC server and other MEC servers
The distribution rules of business, i.e. SMF entity are that MEC server and other MEC servers establish uplink classifier.That is, if
Core network service meets the parameter of the first PDU session, then the core network service is distributed to MEC server, if core network service
Meet the parameter of the 2nd PDU session, then the core network service is distributed to other MEC servers.
Optionally, after step 304, SMF entity sends the second session updates to AMF entity and completes information, and the second session is more
The parameter that new completion information is used to indicate the 2nd PDU session is updated successfully.
It should be noted that conditioning step 303 and step 304 do not execute sequence to the embodiment of the present application, for example, can be first
It executes step 303 and executes step 304 again, step 304 can also be first carried out and execute step 303 again.
It is further alternative, in second of realization scene of method shown in Fig. 3, as shown in figure 5, method shown in Fig. 4 is also
Including step 305.
Step 305:SMF entity receives the configuration change information for the user equipment that AMF entity is sent.
Wherein, AMF entity can be the AMF 106 in Fig. 2.
Wherein, which can serve to indicate that SMF entity other MEC servers cannot mention for user equipment
For service.Configuration change information may include the mark of other MEC servers.
It should be noted that the location information that the available user equipment of AMF entity is current, when user equipment has left this
When other MEC server coverages, which cannot provide service to the user equipment, at this point, AMF entity
Configuration update message can be sent to user equipment, which can be used for updating the access in user device configuration
Management and mobile management parameter, which may include: tracking zone list, mobility limitation, local access network
Information and the whole world 5G unique temporary identity symbol etc., after user equipment has updated access-in management and mobile management parameter, may be used also
Completion message is updated to send configuration to AMF entity, configuration update completes message and is used to indicate access-in management and mobile management
Parameter, which updates, to be completed.After the configuration that AMF entity receives user equipment transmission updates completion message, it can be sent to SMF entity
The configuration change information of user equipment, and then SMF entity can establish the first PDU session of MEC server and user equipment.
Further alternative, the third of method shown in Fig. 3 is realized in scene, user equipment and other MEC servers
The 2nd PDU session is established, includes the following steps 1- step 4:
Step 1: other MEC servers obtain the first query information that user equipment is sent, which includes
First domain name.
Optionally, if user equipment has traffic to carry out, such as: user watches video, Yong Hushe by user equipment
It is standby the first inquiry letter to be sent to operator DNS server through wireless access network (Radio Access Network, RAN)
Breath, first query information include the first domain name, which, should for inquiring the corresponding IP address of the first domain name
The information of the business of user equipment progress is stored in the server of the corresponding IP address of first domain name, such as: user wants to see
The video seen.
Optionally, other MEC servers send the first query information to operator DNS server through RAN in user equipment
Way in, obtain first query information.
If step 2, other MEC servers store first domain name, i.e., other MEC servers can provide for user equipment
Service, other MEC servers send the corresponding resource information of the first domain name to user equipment.
Step 3, other MEC servers send the request of the 2nd PDU session establishment to user equipment.
