Abstract

System(s) and method(s) are provided for prioritizing protocol messages received at a server. A client generates a request message and incorporates a data unit therein in order to indicate type of service application that triggered generation of the request message. The client conveys the request message to a server configured to respond to the request message. To supply data in response to the message request, the server prioritizes the request message based at least on the data unit that conveys the type of service application. The server can assign a set of request messages to a group of scheduling queues based at least on ranking of the type of service associated with at least one request message in the set of request messages. Based on performance conditions, the server also can reject one or more request messages according to the ranking.

Claims

1. A method, comprising:

receiving, by a server device comprising a processor of a telecommunications network, request data indicative of a first authorization, authentication, and accounting request of authorization, authentication, and accounting requests, from a client device of the telecommunications network, wherein the request data comprises classification data representing types of applications that trigger the authorization, authentication, and accounting requests, and wherein the authorization, authentication, and accounting requests are received according to a first order;

determining, by the server device, whether a condition related to a key performance indicator has been satisfied;

in response to the determining, rejecting, by the server device, a second authorization, authentication, and accounting request of the authorization, authentication, and accounting requests;

based on the classification data and the determining, generating, by the server device, scheduling policy data indicative of a policy that specifies priority values of execution priorities of the types of applications, and specifies a second order in which the authorization, authentication, and accounting requests are to be processed based on the priority values; and

based on the scheduling policy data, facilitating, by the server device, a processing of the requests according to the second order.

2. The method of claim 1, wherein the receiving comprises receiving the request data indicative of a first request triggered by a first application and a second request triggered by a second application, and wherein the first request and the second request comprise a common message type.

3. The method of claim 1, wherein the first authorization, authentication, and accounting message conforms to an authentication, authorization, and accounting protocol.

4. The method of claim 3, wherein the classification data comprises an attribute-value pair associated with the authentication, authorization, and accounting protocol.

5. The method of claim 1, further comprising:

based on the scheduling policy data, assigning, by the server device, a third authorization, authentication, and accounting request, of the authorization, authentication, and accounting requests, to a queue of a group of rejected authorization, authentication, and accounting requests.

6. The method of claim 1, wherein the condition is related to a number of the authorization, authentication, and accounting requests received by the server device.

7. A system comprising:

a processor; and

a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising;

receiving, from a mobile device of a telecommunications network, message data indicative of authorization, authentication, and accounting requests that are received by a subscriber server device in a first order, wherein the authorization, authentication, and accounting requests comprise classification data representing respective types of applications that initiate the authorization, authentication, and accounting requests;

in response to determining whether a condition associated with a key performance indicator, of key performance indicators, has been determined to have been satisfied, generating severity data indicative of a number of the key performance indicators that have been determined to have been overloaded;

in response to the generating, dropping an authorization, authentication, and accounting request of the authorization, authentication, and accounting requests resulting in modified authorization, authentication, and accounting requests;

based on the classification data, determining a priority value; and

based on the priority value, determining a second order in which the modified authorization, authentication, and accounting requests are to be processed.

8. The system of claim 7, wherein the authorization, authentication, and accounting request is received in a format in accordance with an authentication, authorization, and accounting protocol.

9. The system of claim 8, wherein the classification data comprises a data unit specific to the authentication, authorization, and accounting protocol.

10. The system of claim 9, wherein the authentication, authorization, and accounting protocol is a diameter protocol, and wherein the data unit specific to the authentication, authorization, and accounting protocol is an attribute value pair.

11. The system of claim 7, wherein the operations further comprise:

based on the classification data, determining scheduling policy data that is employable to determine priority values indicative of execution priorities of respective ones of the respective types of applications.

12. The system of claim 11, wherein the determining the scheduling policy data comprises determining the scheduling policy data based on prioritization data associated with a class of service.

13. The system of claim 11, wherein the operations further comprise:

based on the scheduling policy data, responding to the authorization, authentication, and accounting request in the second order.

14. The system of claim 11, wherein the operations further comprise:

based on the priority values, assigning the authorization, authentication, and accounting request to a defined scheduling queue.

15. The system of claim 14, wherein the defined scheduling queue is configured to drop the authorization, authentication, and accounting request from the authorization, authentication, and accounting requests resulting in the modified authorization, authentication, and accounting requests.

16. The system of claim 11, wherein the operations further comprise:

in response to a determination that performance data indicative of a performance of the subscriber server device satisfies an overload condition, assessing the performance data for severity data related to a severity of an overload.

17. A non-transitory machine-readable storage device, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:

receiving, from a client device of a network, request data indicative of authorization, authentication, and accounting requests that are received by a server device of the network in a first order, wherein the request data comprises classification data representing types of applications that initiate the authorization, authentication, and accounting requests;

based on an indication that a number of key performance indicators are overloaded, generating priority values indicative of execution priorities for the authorization, authentication, and accounting requests;

generating, based at least in part on the classification data, scheduling policy data that is utilized to determine a second order in which the authorization, authentication, and accounting requests are to be scheduled based on the priority values; and

based on the scheduling policy data, facilitating a scheduling of the authorization, authentication, and accounting requests in accordance with the second order.

18. The non-transitory machine-readable storage device of claim 17, wherein the classifications of the types of the applications that initiate the authorization, authentication, and accounting requests comprise the classifications of the types of the applications that initiate the authorization, authentication, and accounting requests in response to execution by the client device of the network.
