Definitions
- the present invention relates to the field of communications, and more particularly to an end-to-end overload control method for Diameter applications and a network element implementing the method. Background technique
- the Diameter out protocol defined in RFC 3588 is intended to provide an Authentication, Authorization, and Accounting (AAA) framework for applications such as network-in-service or mobile IP.
- AAA Authentication, Authorization, and Accounting
- the current Diameter standard document specifies the message format, transport, error reporting, billing, and security services to be used by all Diameter applications.
- Protocol elements consist of numerous commands and AVPs (attribute value pairs) that pass authentication, authorization, and accounting information between clients, agents, and servers. However, whether it is a client, a proxy or a server, the session request can be actively sent, and the other party gives a response, so it is also called an agreement between peer entities.
- Command codes, AVP values, and categories can all be extended by application needs and rules.
- IP networks more and more standards, specifications, and IP products use Diameter as AAA and other control protocols.
- the IP networks herein are, for example, the IPQoS Control Subsystem defined in the TISAPN, 3GPP, 3GPP2 standards, Next Generation Network (NGN), and IP Multimedia Subsystem (IMS).
- NTN Next Generation Network
- IMS IP Multimedia Subsystem
- Diameter is a relatively new protocol, there is no existing method for end-to-end Diameter application overload control. This is a major drawback in the Diameter protocol because overload control is one of the key features of the product due to capacity, performance and reliability. Summary of the invention
- the present invention provides sufficient end-to-end overload control and products using the Diameter protocol for Diameter applications.
- the Diameter application server/client
- the present invention proposes a method for performing overload control between a first application and a second application based on the Diameter protocol, including:
- the overload control information is set and sent to the second application; and the second application takes an action according to the overload control information.
- the overload control information is sent to the second application via a Diameter response message.
- the overload control information is transmitted to the second application via a call disconnection request CGR message.
- the overload control information is a combined overload attribute value pair.
- the combined overload attribute value pair includes a load level attribute value pair defining a current state of the load, an overload control duration attribute value pair defining an overload control duration, and an overload control action attribute value pair defining an action taken during an overload control duration And a request transmission frequency attribute value pair that defines a transmission frequency of the request message during the duration of the overload control.
- the invention also proposes a network unit based on the Diameter protocol, which comprises an overload control initiating device, the overload control initiating device being configured to: set overload control information to be sent to the opposite end of communication with the network unit when an overload occurs Network unit.
- the present invention also provides a network unit based on the Diameter protocol, which includes an overload control response device, and the overload control response device is configured to: when receiving the overload control information sent by the opposite end, according to the The overload control information takes action.
- the overload control mechanism of the present invention is an end-to-end overload control mechanism between the Diameter server and the Diameter client, such that overload information, requests and responses can be sent from one Diameter application to any other via more than one Diameter agent or relay node.
- the Diameter application, and the intermediate Diameter agent or relay node does not have to support or know the method or take any action, they simply forward the Diameter command / AVP transparently, which will save the workload on these intermediate Diameter nodes.

- AAR and AAA DIAMETER messages are used as requests and responses for specific applications in embodiments of the invention, and indeed the method of the present invention can be implemented by means of any DIAMETER request and response.
- Figure 1 shows an example of initiating Diameter overload control via a Diameter response message.
- the entities involved are Application A, Application B, Application A can be a Diameter server, Application B is a Diameter client, or Application A can be a Diameter client, and Application B is a Diameter server, whether it is a server or a client. It is possible for the machine to initiate an overload control request.
- Level nodes we call them "intermediate nodes". These intermediate nodes only need to transparently forward overload request or response messages without participating in overload control.
- step 101 it is assumed that the application A sends an AAR (authentication, authorization request) to the application B, and the intermediate node transparently forwards the AAR request.
- step 102 the application B finds that the AAR message cannot be processed, for example because the load is heavy; then in step 103, the application B fills the overload AVP in the response AAA message to be sent back to the application A and sets the value of the resultcode AVP to " Too busy”.
- step 104 the application B sends the response AAA message to the application A.
- the intermediate node does not participate in the overload control, and transparently forwards the message to the application A.
- application A accepts the response AAA message it discovers the overloaded AVP in the message and takes the corresponding action according to the value of the overload AVP, as shown in step 105.
- the overload AVP herein may be a combined Over-load_AVP, which is to implement the present invention.
- the new Diameter AVP proposed by the overload control mechanism includes a load status and overload control request for the Diameter application end-to-end overload control, and the AVP can be included in any Diameter response message or included in any Diameter command.
- Combination Over-load—AVP can contain the following sub-AVPs:
- Load_level_AVP the load level AVP, which represents the load status of the Diameter application. Its value can be, for example, overload—minor, overload_critical, normal, and so on. Of course, the level can be more carefully divided according to actual needs.
- Overload_duration_AVP the overload control duration AVP. This AVP indicates the expiration date of the overload control request.
- o 2 - only send requests for replying with Diameter; o 3 - send the request only at a frequency lower than the value in the AVP;
- AVP This AVP indicates the maximum transmission frequency that the requested party can send to the party requesting the overload control.
- the application for initiating the overload control in the present invention may be a diameter client or a diameter server.
- step 105 when application A receives the response AAA message, it discovers the overloaded AVP in the message and takes the corresponding action according to the value of the overload AVP.
- the action taken by the application A is based on the combination of Over-load-AVP, that is, the aforementioned Load Level AVP Overload duration AVP, Overload-Action AVP, and Request-sending frequency AVP.
- the Load level is set.
- AVP overload minor
- Overload Action AVP 3
- Request sending frequency AVP 60 seconds
- Overload duration - AVP 900 seconds.
- This set of values means that the request is sent to the party that initiated the overload control (ie, Application B) at a frequency of less than 60 seconds for a duration of 900 seconds.
- step 105 alleviates the load of application B.
- Overload_duration—AVP expires, the end-to-end overload control ends, and Application B determines whether it needs to start the overload control again based on its current load status. If necessary, initiate overload control again.
- 2 illustrates an example of initiating Diameter overload control via a particular CGR/CGA command, in accordance with an embodiment of the present invention. It is particularly important to mention here that CGR/CGA is a new Diameter command that is extended to support the Diameter end-to-end overload control based on the RFC 3588 protocol. This command contains the combination Over_load_ AVP mentioned above.
- the CGR command that is, the call disconnection request, sends the request to specifically request the remote end to start the overload control process according to the over-load AVP in the command.
- the CGA command that is, the call break response, sends the CGA command back from the far end if the CGR is accepted or not accepted.
- application A such as a Diameter client or a Diameter server, finds itself in an overload state, as shown in step 201.
- the application B receives the CGR request command, decodes the overload AVP, and then determines whether the action can be taken according to the AVP value.
- the application B determines that the action can be taken according to the AVP value, that is, the load control can be performed in conjunction with the application A, it generates a CGA response command paired with the CGR, and sends the response command CGA to the application A as a reply.
- the value of resultcodeAVP is set to "2001" ( DIAMETER - SUCCESS ), which means that the request is successful.
- step 205 application A and application B take corresponding actions based on the value of the overload AVP to perform overload control.
- Application B no longer sends a request to Application A for a duration of 900 seconds. It was not until 900 seconds expired that the two parties began normal communication.
- Related request/response messages or CGR/CGA commands in which the forwarding of messages or commands for these intermediate nodes is omitted in the embodiment with reference to FIG. The description is made to make the description of the present invention clearer.
- the overloaded AVP value can be added to the Diameter response message to notify the other party to start the overload control during the session, or can actively generate the CGR message and the message when it finds that it is in an overload condition. Add an overload AVP value to invite the other party to start overload control.
- the specific overload control action between Application A and Application B depends on the value of the overload AVP.
- step 303 application B receives the CGR request command, decodes the overload AVP, and then takes an action to cancel the overload control it is using.
- step 304 the application B generates a CGA response command, and sends a response command CGA to the application A as a reply, in which the value of the resultcodeAVP is set to
- FIG. 4 shows a block diagram of an overload control initiating device 400 included in a Diameter application according to an embodiment of the present invention.
- the Diameter application corresponds to the application A given in Figure 2, namely the overload control initiator.
- Application A can be a Diameter server or it can be Diameter client.
- the application A installs the overload control initiation device 400 of the present invention.
- the device 400 can include an overload control information setting module 401, an assembly module 402, a CGR message generation module 403, and a send response message module 404.
- the overloaded AVP is assembled, it is sent to the peer according to the existing status via the DIAMETER response message or CGR. In this embodiment, the CGR is sent to the peer.
- the CGR generation module 403 in the figure is used to generate a CGR command, and the set combination Overload_AVP is added to the CGR generation module 403 by the assembly module 402 to generate a CGR command message, and the related transmission device of the application A (not shown) Show) sending the CGR message to Application B. It is conceivable that if the overload AVP is sent to the peer through a response message such as AAA Diameter, then in this case, the assembled overload AVP is sent to the opposite end via the send response message module 404, which is carried in the Diameter response message.
- FIG. 5 shows a functional block diagram of the overload control response device 500 of the application B corresponding to the overload control initiating device 400 of the application A in FIG.
- the apparatus 500 further includes a CGA generation module 501, an overload control initiation module 501, a timer 504, a timer 505, and the like.
- the CGA 501 receives the CGR request command, decodes the overloaded AVP, and then determines whether an action can be taken in accordance with the AVP value.
- the application B determines that the action can be taken according to the AVP value, that is, the application A can be used for overload control, it generates a CGA response command paired with the CGR, and sends the response command CGA to the application A as a reply, in which the response command is used.
- the value of resultcode AVP is set to "2001", which means that the request is successful.
- FIG. 4 and 5 illustrate an overload control initiating device 400 and an overload control response device 500, respectively, in accordance with an embodiment of the present invention, which are known to those skilled in the art in understanding the principles of the present invention.
- the apparatus and modules may be implemented by computer software, and the apparatus and modules themselves may be variously modified within the scope of the basic idea of the invention.
- both the Diameter server and the Diameter client can actively initiate overload control, and both can respond to the overload control initiated by the peer. Therefore, the Diameter application preferably includes both an overload control initiator. Also included is an overload control response device.
