Abstract

Various embodiments of the teachings herein include methods for implementing communication conversion between a server-client system and a publish-subscribe (pub-sub) system. An example may include: receiving a message from the pub-sub system, wherein a topic of the message includes information related to a target service in the server-client system to which the message is to be sent, and a payload of the message includes identification information of a consumer in the pub-sub system, wherein the consumer is to receive a response message from the server-client system; parsing the message to determine a host and a service provider that provide the target service, and the consumer who is to receive the response message; sending a request message for the target service to the service provider on the determined host; receiving the response message; adding the identification information to the response message; and sending it to the pub-sub system.

First claim

What is claimed is:

1 . A method for implementing communication conversion between a server-client system and a publish-subscribe (pub-sub) system, the method comprising:
receiving a message from the pub-sub system, wherein a topic of the message includes information related to a target service in the server-client system to which the message is to be sent, and a payload of the message includes identification information of a consumer in the pub-sub system, wherein the consumer is to receive a response message from the server-client system; parsing the message to determine a host and a service provider that provide the target service, and the consumer who is to receive the response message; sending a request message for the target service to the service provider on the determined host; receiving the response message from the service provider; and adding the identification information of the consumer to the response message and sending the response message to the pub-sub system.

2 . The method according to claim 1 , wherein the topic of the message comprises a name and service and a service provider name providing the target service and a name of the target service.

3 . The method according to claim 1 , wherein the payload of the message further comprises a function name and a parameter that correspond to the target service to be subscribed to by the consumer.

4 . The method according to claim 1 , wherein before the receiving a message from the pub-sub system, the method further comprises:
scanning a service provided by the service provider in the server-client system; and publishing the service in the pub-sub system, such that the consumer in the pub-sub system is capable of establishing a connection with the service provider of the service in which the consumer is interested.

5 . A gateway device comprising:
a pub-sub system message receiving unit configured to receive a message from the pub-sub system, a topic of the message comprising information related to a target service in the server-client system to which the message is to be sent, and a payload of the message comprising identification information of a consumer in the pub-sub system, and the consumer is to receive a response message from the server-client system; a parsing unit configured to parse the message to determine a host and a service provider that provide the target service and the consumer who is to receive the response message; a request message sending unit configured to send a request message for the target service to the service provider on the determined host; a response message receiving unit configured to receive the response message from the service provider; and a server-client system message sending unit configured to add the identification information of the consumer to the response message, and send the response message to the pub-sub system.

6 . The gateway device according to claim 5 , wherein the topic of the message comprises the names of the host and the service provider that provide the target service and the name of the target service.

7 . The gateway device according to claim 5 , wherein the payload of the message further comprises a function name and a parameter that correspond to the target service to be subscribed to by the consumer.

8 . The gateway device according to claim 5 , further comprising
a service scanning unit configured to scan a service provided by the service provider in the server-client system, and publish the service in the pub-sub system, such that the consumer in the pub-sub system is capable of establishing a connection with the service provider of the service to which the consumer wants to subscribe.

9 . (canceled)

10 . A gateway device comprising:
a processor; and a memory coupled to the processor, wherein the memory stores instructions that, when executed by the processor, cause the processor to: receive a message from the pub-sub system, wherein a topic of the message includes information related to a target service in the server-client system to which the message is to be sent, and a payload of the message includes identification information of a consumer in the pub-sub system, wherein the consumer is to receive a response message from the server-client system; parse the message to determine a host and a service provider that provide the target service, and the consumer who is to receive the response message; send a request message for the target service to the service provider on the determined host; receive the response message from the service provider; and add the identification information of the consumer to the response message and sending the response message to the pub-sub system.

11 - 13 . (canceled)
