Radio access network slice generation method, radio access network, and slice manager
This patent application discloses a radio access network slice generation method, a radio access network, and a slice manager. The method includes: receiving, by a radio access network, a radio access network slice generation request message sent by a slice manager; and generating, by the radio access network, a radio access network slice. The radio access network slice generation request message includes information about a service type, and a protocol stack corresponding to the service type is configured for the radio access network slice. In this patent application, there is no need to repeatedly deploy different radio access networks to meet different service types, and therefore operating expenses are reduced. The radio access network slice may be quickly generated, and this facilitates rapid deployment of a new service.
1. A method comprising:
receiving, by a gateway from a radio access network (RAN), a RAN slice access request message, wherein the RAN slice access request message comprises information about a service type;
sending, by the gateway to the RAN, a RAN slice access response message, wherein the RAN slice access response message comprises context information of the gateway including access capability information;
after receiving the slice access response message, generating, by the RAN, a RAN slice; and
after generating the RAN slice, sending, by the RAN to a slice manager, a RAN slice generation response message, wherein the slice manager is connected to the gateway.
2. The method of claim 1 , wherein the service type comprises a mobile broadband (MBB) service or a narrowband internet of things (NB-IoT) service.
3. The method of claim 1 , wherein the information about a service type further comprises an operator type.
4. The method of claim 3 , wherein the operator type is a virtual network operator type.
5. The method of claim 1 , wherein the RAN slice access request message further comprises a tracking area code.
6. The method of claim 1 , further comprising:
determining, by the gateway, whether to allow access of the RAN slice based on the service type.
7. A method comprising:
receiving, by a radio access network (RAN) from a slice manager, a RAN slice generation request message, wherein the slice manager is connected to at least one gateway;
sending, by the RAN to the at least one gateway, a RAN slice access request message;
receiving, by the RAN from the at least one gateway, a RAN slice access response message; and
after receiving the slice access response message, generating, by the RAN, a RAN slice, wherein the RAN slice access request message comprises information about a service type.
8. The method of claim 7 , wherein the information about a service type further comprises an operator type.
9. The method of claim 7 , wherein the RAN comprises one or more RAN slices, a protocol stack corresponding to the service type is configured for the one or more RAN slices.
10. A radio access network (RAN), comprising:
a transceiver;
a memory, configured to store an instruction; and
a processor, wherein the processor is separately connected to the memory and the transceiver, and is configured to execute the instruction to perform the following steps when executing the instruction:
receiving, by using the transceiver, a RAN slice generation request message from a slice manager, wherein the slice manager is connected to at least one gateway;
sending, by using the transceiver, a RAN slice access request message to the at least one gateway, wherein the RAN slice access request message comprises information about a service type;
receiving from the at least one gateway, by the RAN, a RAN slice access response message, wherein the RAN slice access response message comprises context information of the at least one gateway including access capability information;
after receiving the slice access response message, generating, by the RAN, a RAN slice; and
after generating the RAN slice, sending to the slice manager, using the transceiver, a RAN slice generation response message.
11. The RAN of claim 10 , wherein the information about a service type further comprises an operator type.
12. The RAN of claim 10 , wherein the RAN comprises:
one or more RAN slices; and
the RAN slice access request message further comprises a protocol stack corresponding to the service type for the one or more RAN slices.
13. A gateway comprising:
a transceiver;
a memory, configured to store an instruction; and
a processor, wherein the processor is separately connected to the memory and the transceiver, and is configured to execute the instruction to perform the following steps when executing the instruction:
receiving from a radio access network (RAN), by the transceiver, a radio RAN slice access request message, wherein the RAN slice access request message comprises information about a service type; and
sending to the RAN, by the transceiver, a RAN slice access response message such that:
after receiving the slice access response message, the RAN generates a RAN slice, wherein the RAN slice access response message comprises context information of the gateway including access capability information; and
after generating the RAN slice, the RAN sends to a slice manager, a RAN slice generation response message,
wherein the gateway is communicatively connected to the slice manager and the RAN.
14. The gateway of claim 13 , wherein the service type comprises a mobile broadband (MBB) service or a narrowband internet of things (NB-IoT) service.
15. The gateway of claim 13 , wherein the information about a service type further comprises an operator type.
