Abstract

Methods, system, and articles are described herein for receiving and prioritizing a plurality of signaling messages based at least on classifications of the signaling messages. At least a number of the signaling messages are processed in order of priority, the number processed being based at least on a volume of the signaling messages.

Claims

1. A computer-implemented method comprising:

receiving a plurality of signaling messages;

prioritizing the signaling messages based at least on classifications of the signaling messages;

processing at least a number of the signaling messages in order of priority, the number processed being based at least on a volume of the signaling messages; and

for at least one unprocessed signaling message, replying to a sender of the at least one unprocessed signaling message with a request that the sender wait for a specified time before sending another signaling message, wherein the specified time is selected based on the classification of the at least one unprocessed signaling message.

2. The method of claim 1, wherein in the signaling message classifications are specified by a signaling classification protocol.

3. The method of claim 2, wherein the prioritizing is further based on rules for handling classifications that are specified by the signaling classification protocol.

4. The method of claim 2, wherein at least one of the classifications is represented within a header of one of the signaling messages by one or more bits of a header field.

5. The method of claim 4, wherein the signaling classification protocol specifies a bit length for a representation of a classification and specifies the header field that is to include the representation.

6. The method of claim 1, wherein the classifications are associated with at least one category, the at least one category including at least one of a voice call, high priority data signaling, low priority data signaling, an update, a packet data protocol (PDP) context establishment, a radio resource control (RRC) connection establishment request, a RRC radio bearer reconfiguration, a RRC release, a RRC paging message, cell updates, a session initiation protocol (SIP) request or response, or a specific type of SIP request or response.

7. The method of claim 1, wherein the prioritizing is further based on rules for handling classifications that are determined by an operator or service provider.

8. The method of claim 1, further comprising:

comparing the volume of the signaling messages to a threshold volume imposed by physical capacities of equipment performing the processing, by an operator, or by a service provider; and

based at least on the comparing, limiting how many of the signaling messages are to be processed.

9. The method of claim 1, further comprising queuing unprocessed signaling messages for later processing.

10. The method of claim 1, wherein the processing includes replying to the signaling messages or performing an act requested by the signaling messages.

11. The method of claim 1, further comprising receiving a payload delivery message associated with one of the signaling messages, the payload delivery message having a classification that is different from the classification of the one of the signaling messages.

12. An article of manufacture comprising:

a tangible storage medium; and

computer-readable programming instructions stored on the tangible storage medium and configured to program a computing device to perform operations including;

receiving a plurality of radio signaling messages;

determining whether a volume of the signaling messages exceeds a threshold; and

responsive to determining that the volume of the radio signaling messages exceeds the threshold,

prioritizing the radio signaling messages based at least on classifications of the radio signaling messages;

processing at least a number of the radio signaling messages in order of priority, the number processed being based at least on the volume of the radio signaling messages; and

for at least one unprocessed radio signaling message, replying to a sender of the at least one unprocessed radio signaling message with a request that the sender wait for a specified time before sending another signaling message, wherein the replying is performed conditionally based on determining that the at least one unprocessed radio signaling message is associated with a specific classification included in a radio signaling classification protocol.

13. The article of claim 12, wherein the wait specified in the request is determined based at least on a classification of the at least one unprocessed radio signaling message.

14. The article of claim 12, wherein the operations further include discarding the at least one unprocessed radio signaling message after performing the replying.

15. A telecommunication device comprising:

a processor; and

a plurality of programming instructions configured to be operated by the processor to perform operations including;

formulating a signaling message, including determining a classification associated with the signaling message based on a signaling classification protocol; and

transmitting the signaling message to a server for processing in accordance with the signaling message classification,

wherein the signaling classification protocol specifies;

when a first communication protocol is used, a first bit length for a representation of the classification and a first header field of the signaling message that is to include the representation, and

when a second communication protocol is used, a second bit length for the representation of the classification and a second header field of the signaling message that is to include the representation,

the first bit length and second bit length being different bit lengths, the first header field and second header field being different header fields, and the first and second communication protocols are different communication protocols.

16. The telecommunication device of claim 15, wherein the operations further include:

receiving a reply from the server requesting that the telecommunication device wait for a specified time before sending another signaling message; and

after waiting for the specified time period, re-transmitting the signaling message to the server.

17. The telecommunication device of claim 15, wherein the classification is associated with at least one category, the at least one category including at least one of a voice call, high priority data signaling, low priority data signaling, an update, a packet data protocol (PDP) context establishment, a radio resource control (RRC) connection establishment request, a RRC radio bearer reconfiguration, a RRC release, a RRC paging message, cell updates, a session initiation protocol (SIP) request or response, or a specific type of SIP request or response.
