Method and apparatus for introducing a delay during a call setup in a communication network
View Patent ↗A method and apparatus for providing a capability for placing a slight delay in processing call setup and termination signaling messages in conferencing applications so that the call processing rate requirement on a Call Control Element (CCE) is lowered. For example, allowing conferencing participants of a conference call to join a conference bridge over a 90 second period will significantly improve the processing load on the CCE than allowing them to join in over a 30 second period. In one embodiment, the present invention introduces a configurable delay in the processing of signaling messages for call setups and terminations for high volume calls onto conference bridges.
1. A method for introducing a delay during a call set up in a communication network, comprising:
detecting a call signaling message arrival rate threshold has been exceeded for a call set up; and
if said call signaling message arrival rate threshold has been exceeded for said call set up, then introducing a configurable delay by a Call Control Element (CCE) between each of a plurality of incoming call signaling messages destined to a single phone number associated with said call set up, wherein said introducing said configurable delay between each of a plurality of incoming call signaling messages comprises:
introducing said configurable delay between a start of processing of each of said plurality of incoming call signaling messages destined to said single phone number,
wherein said configurable delay is determined by a number of call legs to be setup to said single phone number divided by a predefined period of time in which the setup of all the call legs is to be completed.
2. A computer-readable storage medium having stored thereon a plurality of instructions, the plurality of instructions including instructions which, when executed by a processor, cause the processor to perform the steps of a method for introducing a delay during a call set up in a communication network, comprising:
detecting a call signaling message arrival rate threshold has been exceeded for a call set up; and
if said call signaling message arrival rate threshold has been exceeded for said call set up, then introducing a configurable delay by a Call Control Element (CCE) between each of a plurality of incoming call signaling messages destined to a single phone number associated with said call set up, wherein said introducing said configurable delay between each of a plurality of incoming call signaling messages comprises:
introducing said configurable delay between a start of processing of each of said plurality of incoming call signaling messages destined to said single phone number,
wherein said configurable delay is determined by a number of call legs to be setup to said single phone number divided by a predefined period of time in which the setup of all the call legs is to be completed.
3. An apparatus for introducing a delay during a call set up in a communication network, comprising:
means for detecting a call signaling message arrival rate threshold has been exceeded for a call set up; and
a Call Control Element (CCE) for introducing a configurable delay between each of a plurality of incoming call signaling messages destined to a single phone number associated with said call set up if said call signaling message arrival rate threshold has been exceeded for said call set up, wherein said introducing said configurable delay between each of a plurality of incoming call signaling messages comprises:
introducing said configurable delay between a start of processing of each of said plurality of incoming call signaling messages destined to said single phone number,
wherein said configurable delay is determined by a number of call legs to be setup to said single phone number divided by a predefined period of time in which the setup of all the call legs is to be completed.
