Problems solved by technology

At this time, the connection between node A and node B has been disconnected, which will cause failure and affect the QoS of the system
[0006] It can be seen that the existing methods of disconnecting Diameter are usually controlled by only one party, and there is a lack of coordination mechanism between the two parties, resulting in various failures

Embodiment Construction

[0028] First explain two nouns:

[0029] Request message (Request): refers to a message initiated by one of the two Diameter nodes communicating with each other, usually the start of a new transaction, and is used to request the other party to complete certain processing actions.

[0030] Reply message (Answer): refers to the message that one of the two Diameter nodes communicating with each other takes some processing actions after receiving the request message sent by the other party, and then replies to the other party that initiated the request message. Usually is the end of a transaction.

[0031] The present invention introduces a new mechanism for smoothly closing Diameter connections.

[0032] The present invention will be described in further detail below with reference to the accompanying drawings.

[0033] figure 2 An application scenario diagram according to an embodiment of the present invention is shown. Wherein, both the node 201 and the node 202 are Diamet...

Abstract

The invention aims to provide a method and a device for closing Diameter connection. The first Diameter node starts the first timer, when the first timer overtimes or the transmit queue to be opened on connection is empty, sending the disconnection request message to the second Diameter node. Then, at one side of the second Diameter node, starting the third timer, when the third timer overtimes or the transmit queue to be opened on connection and the receiving queue are empty, sending the disconnection reply message to the first Diameter node. At one side of the first Diameter node, the second timer is started, and breaking the Diameter connection when the second timer overtimes or receives the disconnection reply message. The number of the failure can be obviously reduced through the method and the device, under reasonable setting of the timer, the ideal effect without failure message can be achieved and the QoS and stability of the system can be raised.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a technology for processing Diameter connections. Background technique [0002] The current Diameter standard does not clearly stipulate the process of graceful shutdown (Graceful Shutdown) of Diameter connections. In the current standard, any one of the communication parties can initiate a disconnection request (DPR, Disconnect Peer Request) to terminate the connection, and the other party replies with a disconnection response (DPA, Disconnect Peer Answer). After that, the communication between the two parties is disconnected. open. However, this only terminates new Diameter transactions. For Diameter transactions in progress at the time of disconnection, almost all of them will fail. Specifically, if the message has been sent, it will fail due to timeout, and if the message has not been sent, it will fail immediately. This failure will definitely affect QoS, especially...
