Method and device for acquiring response message, method and device for routing response message, and system for acquiring response message and routing response message

A method for routing a response message, comprising:

• receiving, by a destination node, a service request message from a source node via a first group of Diameter routing agent (DRA) nodes, wherein first identification information, second identification information and third identification information are carried in the service request message, the first identification information is an identifier of the destination node, the second identification information is used for indicating the first group of DRA nodes to route the service request message according to the first identification information and indicating the destination node to configure first identification information of a service response message to the third identification information, and the third identification information is used for identifying the source node;
• and
• configuring, by the destination node, the first identification information of the service response message to the third identification information according to the second identification information and returning, by the destination node, the service response message to the source node via a second group of nodes, wherein the second group of nodes include:
• the destination node and a second group of DRA nodes.

A device for acquiring a response message, comprising:

• a sending component arranged to send a service request message to a second group of nodes via a first group of Diameter routing agent (DRA) nodes, wherein the second group of nodes include:
• a destination node and a second group of DRA nodes;
• first identification information, second identification information and third identification information are carried in the service request message, wherein the first identification information is used for identifying the destination node, the second identification information is used for indicating the first group of DRA nodes to route the service request message according to the first identification information and indicating the destination node to configure first identification information of a service response message to the third identification information of the service request message, and the third identification information is used for identifying a source node;
• and
• an acquisition component arranged to acquire the service response message returned by the destination node via the second group of nodes.

A device for routing a response message, comprising:

• a receiving component arranged to receive a service request message from a source node via a first group of Diameter routing agent (DRA) nodes, wherein first identification information, second identification information and third identification information are carried in the service request message, the first identification information of the service request message is an identifier of a destination node, the second identification information is used for indicating the first group of DRA nodes to route the service request message according to the first identification information and indicating the destination node to configure first identification information of a service response message to the third identification information, and the third identification information is used for identifying the source node;
• and
• a determination component arranged to configure the first identification information of the service response message to the third identification information according to the second identification information and return the service response message to the source node via a second group of nodes, wherein the second group of nodes include:
• the destination node and a second group of DRA nodes.
