SYSTEM AND METHOD FOR ROUTING EMERGENCY SERVICES CALLS FROM FIXED WIRELESS TERMINALS

摘要

A method for routing emergency services calls from a subscriber's fixed wireless terminal to a PSAP that serves the location of the subscriber and for delivering traditional landline ALI information associated with the subscriber to the PSAP. The method includes: (a) querying a subscriber database using the subscriber's calling party identifier, wherein the calling party identifier is one or more of an MSISDN, MDN, Calling Party Address or ANI; (b) determining that the subscriber is associated with a fixed wireless terminal; (c) assigning the subscriber's MSISDN as the calling party identifier; (d) assigning Selective Router routing information, wherein the routing information comprises trunk select digits or an ESRN; (e) routing the emergency services call using the assigned Selective Router routing information to the Selective Router and including the MSISDN as the calling party number; and (f) delivering the emergency services call to the PSAP including an ESN assigned to the MSISDN. The method provides routing by “TrunkSelect”+MSISDN and routing by ESRN+MSISDN, in place of the wireless industry-standard “TrunkSelect”+ESRK.
