For the message that does not send in proper order according to service analogue device 102/104/106/108 setting process that BSS sends, service analogue device 102/104/106/108 provides exception handling to handle these message, so that call flow is unlikely to interrupt.
Fig. 5 is the workflow diagram of Bulk Call test macro, may further comprise the steps:
Step 501: simulation MSS sends call request to BSS.
Step 502: if the call request of simulation MSS is admitted by BSS, BSS starts the network insertion process of simulation MSS.
Step 503: simulation MSS begins to set up professional the connection with BSS.
Both can send the professional request of foundation that connects to BSS, also can initiatively send the professional request of foundation that connects by BSS to simulation MSS by simulation MSS.
Its successful call number of times of service analogue device real time record and the up-downgoing message throughput at simulation MSS place regularly or after receiving control backstage 101 query requests, report control backstage 101 and show and add up.Wherein, (be generally one hour) in the unit interval, the maximum successful call number of times sum of all simulation MSS of control backstage 101 statistics is BHCA, and the maximum up-downgoing message throughput sum of the MSS of all simulations is a maximum throughput.
Step 504: first timer is set, and this first timer duration is the Business Stream keep-alive duration that defines in the configuration parameter.Simulation MSS keeps being connected with the business of BSS, receives packet to the BSS transmission or from BSS, and is overtime up to first timer.
Step 505: after first timer was overtime, simulation MSS release was connected with BSS's;
Step 506: second timer is set, and this second timer duration is the flow process intercycle that defines in the configuration parameter.After this second timer is overtime,, will turn back to step 501 if simulation MSS does not finish the flow process cycle-index that defines in the configuration parameter.
