54	Superfluous warning for unused timer formal parameters	phdmakk		"The issue seems to be related to incorrect search for timer references.

Original report:

The error reported is:

""..\ttcn\IMS\19\IMS_CC_EmergencyCallTestcases.ttcn: 48: WARNING: Code Style: Formal parameter ""p_TRegExpireMax"" in definition for ""fl_IMS_EmergencyReRegistration"" is never used! (6.11, checkNoUnusedFormalParameters)""

But within fl_IMS_EmergencyReRegistration the timer p_TRegExpireMax gets stopped i.e. it is used, probably stopping of a timer is not considered correctly by T3Qv2 on this rule as stopping it should be considered using the variable.

On the same delivery mentioned below, on ATS IMS_Testsuite_EUTRA, you can find on module ""..\IMS_EUTRA_IWD_17wk10\IMS\19\IMS_CC_EmergencyCallTestcases.ttcn"", line 83, the mentioned object fl_IMS_EmergencyReRegistration.

The code snippet of the function below:

//============================================================================

/*

* @desc Emergency Reregistration

* @param p_OldSecNotRequired (default value: true)

* @param p_RegisterExpiration (default value: tsc_IMS_RegisterExpiration)

* @param p_TRegExpireMax

* @return REGISTER_Request

* @status APPROVED (IMS)
