Public safety communications incident response

摘要

A system and method permit communications of a mobile station of emergency service personnel while blocking communications of mobile stations of other users. In response to an emergency in a region, a mobile switching center may be configured to restrict communications of mobile stations in the region through an identified cell site base station controlled by the mobile switching center during the emergency while the identified cell site base station continues wireless radio frequency transmissions. This configuration may be accomplished with the use of a trigger, such as a Specific_Called_Party_Digit_String trigger. While the mobile switching center is configured for the emergency, a designated trigger condition may be detected with respect to an attempted communication for a mobile station through the identified cell site base station.

1. A method, comprising steps of:
in response to an emergency in a region, configuring an originating mobile switching center switch of a mobile communication network to selectively permit, during the emergency, emergency communications originating from mobile stations in the region through a transceiver of a plurality of transceivers that serve a cell site controlled by the originating mobile switching center switch; identifying a transceiver from among the plurality of transceivers that sent the detected appropriate sequence of destination digits received by the originating mobile switching center switch; based on the originating mobile switching center switch configuration, implementing an origination trigger for the originating mobile switching center switch, wherein the origination trigger designates a Specific_Called_Party_Digit_String trigger condition based on a sequence of destination digits for attempted communications through the identified transceiver; while the originating mobile switching center switch is configured for the emergency, in response to an attempted communication through the identified transceiver originating from a mobile station of a user other than emergency service personnel, detecting within the originating mobile switching center switch receipt of an appropriate sequence of destination digits from the mobile station that satisfies the Specific_Called_Party_Digit_String trigger condition; based on the detected appropriate sequence of destination digits of the Specific_Called_Party_Digit_String trigger condition sent by the identified transceiver, responsive to the detected designated trigger condition, querying a service control point coupled to the switch for instructions with respect to the attempted communication through the identified transceiver originating from the mobile station; receiving instructions from the service control point in response to the querying, indicating that the detected designated trigger condition is satisfied based upon a determination that the attempted communication is an emergency communication; responsive to the instructions received from the service control point, completing by the originating mobile switching center switch the attempted communication through the identified transceiver originating from the mobile station based on the determination that the attempted communication is an emergency communication directed to a public safety entity; and while the switch is configured for the emergency, blocking all originating communication attempts for non-emergency communications from other mobile stations through the identified cell site base station for which the designated trigger condition is not detected.
