Abstract

The disclosure provides communication methods and apparatuses. One example method includes receiving, by a first network device, a first message from a second network device, where the first message includes network slice configuration information. The network slice configuration information is used to indicate a maximum data rate provided by each of n network slices for a terminal device, and n is an integer greater than or equal to 1. In response to the received first message, the first network device sends a second message to the second network device.

First claim

What is claimed is:

1. A communication method comprises:
receiving, by a first network device, a first message from a second network device, wherein the first message comprises network slice configuration information, the network slice configuration information is used to indicate a maximum data rate provided by each of n network slices for a terminal device, and n is an integer greater than or equal to 1, wherein the network slice configuration information comprises:
first indication information that indicates an aggregate bit rate provided by each of the n network slices for an uplink data flow of the terminal device, wherein the uplink data flow comprises at least one of an uplink non-guaranteed bit rate quality of service (non-GBR QoS) flow or an uplink guaranteed bit rate quality of service (GBR QoS) flow of the terminal device; and
second indication information that indicates an aggregate bit rate provided by each of the n network slices for a downlink data flow of the terminal device, wherein the downlink data flow comprises at least one of a downlink non-GBR QoS flow or a downlink GBR QoS flow; and

sending, by the first network device, a second message to the second network device, wherein the second message is in response to the first message.

2. The method according to claim 1 , wherein:
the first message is a handover request message;
the first message is a UE context setup request message or a UE context modification request message;
the first message is a bearer context setup request message or a bearer context modification request message;
the first message is a secondary node addition request message or a secondary node modification request message; or
the first message is a protocol data unit (PDU) session resource setup request message or an initial context setup request message.

3. The method according to claim 1 , wherein:
the second message is a handover request acknowledge message;
the second message is a UE context setup response message or a UE context modification response message;
the second message is a bearer context setup response message or a bearer context modification response message;
the second message is a secondary node addition request acknowledge message or a secondary node modification request acknowledge message; or
the second message is a PDU session resource setup response message or an initial context setup response message.

4. The method according to claim 1 , wherein the second message indicates that the first network device rejects configuration requirements of maximum data rates provided by m network slices for the terminal device, and m is an integer greater than or equal to 0 and less than or equal to n.

5. The method according to claim 4 , further comprising:
sending, by the first network device, rejection information to the second network device, wherein the rejection information indicates that a reason why the first network device rejects the configuration requirements of maximum data rates provided by m network slices is that the first network device does not support the maximum data rates provided by the m network slices for the terminal device.

6. A communication method comprises:
sending, by a second network device, a first message to a first network device, wherein the first message comprises network slice configuration information, the network slice configuration information is used to indicate a maximum data rate provided by each of n network slices for a terminal device, and n is an integer greater than or equal to 1, wherein the network slice configuration information comprises:
first indication information that indicates an aggregate bit rate provided by each of the n network slices for an uplink data flow of the terminal device, wherein the uplink data flow comprises at least one of an uplink non-guaranteed bit rate quality of service (non-GBR QoS) flow or an uplink guaranteed bit rate quality of service (GBR QoS) flow of the terminal device; and
second indication information that indicates an aggregate bit rate provided by each of the n network slices for a downlink data flow of the terminal device, wherein the downlink data flow comprises at least one of a downlink non-GBR QoS flow or a downlink GBR QoS flow; and

receiving a second message from the first network device, wherein the second message is in response to the first message.

7. The method according to claim 6 , wherein:
the first message is a handover request message;
the first message is a UE context setup request message or a UE context modification request message;
the first message is a bearer context setup request message or a bearer context modification request message;
the first message is a secondary node addition request message or a secondary node modification request message; or
the first message is a protocol data unit (PDU) session resource setup request message or an initial context setup request message.

8. The method according to claim 6 , wherein:
the second message is a handover request acknowledge message;
the second message is a UE context setup response message or a UE context modification response message;
the second message is a bearer context setup response message or a bearer context modification response message;
the second message is a secondary node addition request acknowledge message or a secondary node modification request acknowledge message; or
the second message is a PDU session resource setup response message or an initial context setup response message.

9. The method according to claim 6 , wherein the second message indicates that the first network device rejects configuration requirements of maximum data rates provided by m network slices for the terminal device, and m is an integer greater than or equal to 0 and less than or equal to n.

10. The method according to claim 9 , further comprising:
receiving, by the second network device, rejection information from the first network device, wherein the rejection information indicates that a reason why the first network device rejects the configuration requirements of maximum data rates provided by m network slices is that the first network device does not support the maximum data rates provided by m network slices for the terminal device.

11. A communication apparatus, comprising at least one processor; and
one or more memories are coupled to the at least one processor and storing programming instructions for execution by the at least one processor to perform operations comprising:
receiving a first message from a network device, wherein the first message comprises network slice configuration information, the network slice configuration information is used to indicate a maximum data rate provided by each of n network slices for a terminal device, and n is an integer greater than or equal to 1, wherein the network slice configuration information comprises:
first indication information that indicates an aggregate bit rate provided by each of the n network slices for an uplink data flow of the terminal device, wherein the uplink data flow comprises at least one of an uplink non-guaranteed bit rate quality of service (non-GBR QoS) flow or an uplink guaranteed bit rate quality of service (GBR QoS) flow of the terminal device; and
second indication information that indicates an aggregate bit rate provided by each of the n network slices for a downlink data flow of the terminal device, wherein the downlink data flow comprises at least one of a downlink non-GBR QoS flow or a downlink GBR QoS flow; and

sending a second message to the network device, wherein the second message is in response to the first message.
