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 of a telecommunication network that stores subscriber data associated with subscriber identities subscribed to usage of network devices of the telecommunication network and comprises a processor, request data indicative of an authorization, authentication, and accounting message, in a first order, from a session control gateway device of the telecommunication network, wherein the request data comprises classification data representing respective types of applications that trigger requests in response to execution by a network device of the network devices;

based on the classification data, generating, by the server, 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 requests are to be processed based at least on the priority values; and

based on the scheduling policy data, facilitating, by the server, a processing of the requests in 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 comprising a first application type and a second request triggered by a second application comprising a second application type, and wherein the first request and the second request comprise a common message type.

3. The method of claim 1, wherein the authorization, authentication, and accounting message conforms to an authentication, authorization, and accounting protocol, and wherein the classification data comprises an attribute-value pair associated with the authentication, authorization and accounting protocol.

4. The method of claim 1, further comprising:

based on the scheduling policy data, assigning, by the server, a request of the requests to a queue of a group of scheduling queues.

5. The method of claim 1, wherein the determining comprises determining the scheduling policy data based on performance data indicative of a performance condition of the server.

6. The method of claim 5, wherein the determining comprises determining the scheduling policy information data in response to determining that the performance data satisfies an overload condition.

7. The method of claim 3, wherein the receiving comprises receiving the request data indicative of the authorization, authentication, and accounting message conforming to a diameter protocol.

8. A system comprising:

processor; and

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

receiving, from a session control gateway device of a telecommunication network, message data indicative of authorization, authentication, and accounting messages that are received by a home subscriber server system in a first order, wherein the messages comprise classification data representing respective types of applications that initiate the authorization, authentication, and accounting messages in response to execution by a device of the telecommunication network;

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, and a second order in which the messages are to be processed based at least on the priority values, and

based on the scheduling policy data, responding to the messages in the second order.

9. The system of claim 8, wherein an authorization, authentication, and accounting message of the authorization, authentication, and accounting messages is received in a format in accordance with an authentication, authorization, and accounting protocol, and 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 the data unit specific to the authentication, authorization, and accounting protocol is an attribute value pair.

11. The system of claim 8, wherein the determining comprises determining the scheduling policy data based on class-of-service prioritization data.

12. The system of claim 8, wherein the operations further comprise:

based on the priority values, assigning an authorization, authentication, and accounting message of the authorization, authentication, and accounting messages to a defined scheduling queue.

13. The system of claim 8, wherein the operations further comprise:

assessing performance data indicative of a performance of the home subscriber server system, wherein the determining comprises determining the scheduling policy data in response to a determination that the performance data satisfies an overload condition.

14. The system of claim 8, wherein the home subscriber server system is comprised within a network node device of the telecommunication network, and wherein the telecommunication network comprises an internet protocol multimedia subsystem network device.

15. The system of claim 14, wherein the network node device is a serving-control session control function node device.

16. The system of claim 8, wherein the operations further comprise:

determining that the home subscriber sever satisfies an overload condition; and

based on the priority values, dropping an authorization, authentication, and accounting message of the authorization, authentication, and accounting messages.

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

receiving, from a session control gateway device of the telecommunication network, request data indicative of authorization, authentication, and accounting requests that are received by a server in a first order, wherein the request data comprises classification data representing respective types of applications that initiate the requests in response to execution by a device of the telecommunication network;

based on the classification data, determining scheduling policy data that is utilized to determine priority values indicative of respective execution priorities of the respective types of applications, and a second order in which the requests are to be scheduled based at least on the priority values; and

based on the scheduling policy information, facilitating a scheduling of the requests in accordance with the second order.

18. The non-transitory machine-readable storage device of claim 17, wherein the authorization, authentication, and accounting requests are associated with a common message type and the authorization, authentication, and accounting requests comprise a first request initiated by a first application determined to have a first application type and a second request initiated by a second application determined to have a second application type.

19. The non-transitory machine-readable storage device of claim 18, wherein an authorization, authentication, and accounting request of the authorization, authentication, and accounting requests is a message in an authentication, authorization, and accounting protocol and the classification data comprises a data unit associated with the authorization, authentication, and accounting request that is an attribute-value pair associated with the authentication, authorization, and accounting protocol.

20. The non-transitory machine-readable storage device of claim 17, wherein the operations further comprise:

determining performance data representing a performance of the server wherein the determining the scheduling policy data comprises determining the scheduling policy data in response to determining the performance data satisfies an overload condition.
