Abstract

Systems and methods for calls per second network testing are disclosed. The methods may be performed by a network testing system or other computing device. The method may include receiving user selection to create a network test. A user specification of a bulk network calls test type and the call transmission criteria for the network test are received. The call transmission criteria may include a number of calls per second and one of either a talk time or a number of channels. When the talk time is specified, the number of channels is calculated. Similarly, when the number of channels is specified, the talk time is calculated. User selection to begin the network test is received, and packets are transmitted for the network test according to the call transmission criteria. During transmission, the call transmission criteria are recalculated at a system defined interval to avoid bursts.
