If Nbr_UE is greater than Nbr_SN, the mobile station may initiate an Emergency call even if Nbr_SN has been reached. When the n

The MS shall release one or more existing calls and it shall re-initiate an Emergency call. The MS shall ensure that an emergency call Setup request is acceptable to a serving network which does not support multicall, if necessary by releasing one or more existing calls. 6.2 Short message service No impac
