Abstract

Claims (56)

1 . A message transmission system comprising:

service sets comprising a first service set, wherein the first service set has a first identifier and comprises at least one service instance, wherein the at least one service instance comprises a second service instance, wherein each of the at least one service instance has a same capability information, and wherein the capability information comprises a capability of a supported network slice, a capacity, or a data network name (DNN);

a first service instance configured to:

obtain the first identifier; and

send a first message, wherein the first message is a Hypertext Transfer Protocol (HTTP) message comprising a message header, and wherein the message header comprises the first identifier;

a second transmission proxy connected to the first service instance and configured to:

receive the first message from the first service instance; and

send the first message; and

a first transmission proxy connected to the service sets, based on the first identifier, and configured to:

receive the first message from the second transmission proxy;

obtain the second service instance from the first service set identified by the first identifier; and

send a second message to the second service instance based on the first message,

wherein the first identifier enables determination of the first transmission proxy.

2 . The message transmission system of claim 1 , wherein the first service instance is further configured to obtain the first identifier by:

receiving, from the second service instance, a response message comprising the first identifier; and

obtaining the first identifier from the response message.

3 . The message transmission system of claim 1 , wherein the first service instance is further configured to obtain the first identifier by:

sending the capability information of a requested service instance of the first service instance to a network registration network element; and

receiving the first identifier from the network registration network element, wherein the at least one service instance provides the capability information.

4 . The message transmission system of claim 3 , wherein the first service instance is further configured to receive a second identifier of the first transmission proxy from the network registration network element, and wherein the first transmission proxy corresponds to the first service set.

5 . The message transmission system of claim 3 , wherein the capability information further comprises a serving area or a service type.

6 . The message transmission system of claim 1 , wherein the first transmission proxy is further configured to further obtain the second service instance by:

determining the first service set based on the first identifier; and

determining the second service instance in the first service set based on a load status of each of the at least one service instance.

7 . A message transmission method comprising:

obtaining, by a first service instance, a first identifier of a first service set, wherein the first identifier enables determination of a first transmission proxy that is based on the first identifier, wherein the first service set comprises at least one service instance, wherein the at least one service instance comprises a second service instance, wherein each of the at least one service instance has a same capability information, and wherein the capability information comprises a capability of a supported network slice, a capacity, or a data network name (DNN);

sending, by the first service instance to a second transmission proxy connected to the first service instance, a first message, wherein the first message is a Hypertext Transfer Protocol (HTTP) message comprising a message header, and wherein the message header comprises the first identifier;

receiving, by the second transmission proxy from the first service instance, the first message;

sending, by the second transmission proxy to the first transmission proxy, the first message;

receiving, by the first transmission proxy from the second transmission proxy, the first message, wherein the first transmission proxy is connected to service sets comprising the first service set;

obtaining, by the first transmission proxy, the second service instance from the first service set identified by the first identifier; and

sending, by the first transmission proxy to the second service instance, a second message based on the first message.

8 . The message transmission method of claim 7 , wherein obtaining the first identifier comprises:

receiving, by the first service instance from the second service instance, a response message comprising the first identifier; and

obtaining, by the first service instance from the response message, the first identifier.

9 . The message transmission method of claim 7 , wherein obtaining the first identifier comprises:

sending, by the first service instance to a network registration network element, the capability information of a requested service instance of the first service instance; and

receiving, by the first service instance from the network registration network element, the first identifier, wherein the at least one service instance provides the capability information.

10 . The message transmission method of claim 9 , further comprising receiving, by the first service instance from the network registration network element, a second identifier of the first transmission proxy, wherein the first transmission proxy corresponds to the first service set.

11 . The message transmission method of claim 9 , wherein the capability information further comprises a serving area or a service type.

12 . The message transmission method of claim 7 , wherein obtaining, by the first transmission proxy, the second service instance comprises:

determining the first service set based on the first identifier; and

determining the second service instance in the first service set based on a load status of each of the at least one service instance.

13 . A first service instance apparatus comprising:

a memory configured to store instructions; and

one or more processors coupled to the memory and configured to execute the instructions to cause the first service instance apparatus to:

obtain a first identifier of a first service set, wherein the first identifier enables determination of a first transmission proxy that is based on the first identifier, wherein the first service set comprises at least one service instance, wherein the at least one service instance comprises a second service instance, wherein each of the at least one service instance has a same capability information, and wherein the capability information comprises a capability of a supported network slice, a capacity, or a data network name (DNN); and

send a first message to a second transmission proxy connected to the first service instance apparatus to enable the second transmission proxy to send the first message to the first transmission proxy, wherein the first message is a Hypertext Transfer Protocol (HTTP) message comprising a message header, and wherein the message header comprises the first identifier.

14 . The first service instance apparatus of claim 13 , wherein the one or more processors are further configured to execute the instructions to cause the first service instance apparatus to obtain the first identifier by:

receiving, from the second service instance, a response message comprising the first identifier; and

obtaining the first identifier from the response message.

15 . The first service instance apparatus of claim 13 , wherein the one or more processors are further configured to execute the instructions to cause the first service instance apparatus to obtain the first identifier by:

sending the capability information of a requested service instance of the first service instance apparatus to a network registration network element; and

receiving the first identifier from the network registration network element, wherein the at least one service instance provides the capability information.

16 . The first service instance apparatus of claim 15 , wherein the one or more processors are further configured to execute the instructions to cause the first service instance apparatus to receive a second identifier of the first transmission proxy from the network registration network element, and wherein the first transmission proxy corresponds to the first service set.

17 . The first service instance apparatus of claim 15 , wherein the capability information further comprises a serving area or a service type.
