  • Patent number: 7565130
    Abstract: In the method of emergency service call back in a wireless system, an emergency intersystem page is sent from a first system to a second system such that the emergency intersystem page is identifiable as requesting paging of a mobile station for an emergency call back. The second system receives the mobile station identifier (MSID) and mobile equipment identity (MEID) of the paged mobile station from the first system in or with the emergency intersystem page, and uses the MSID to page the mobile station. The second system verifies the page response is from the paged mobile station using the MEID received from the responding mobile station and the MEID received in association with the emergency intersystem page. The emergency call back can then be completed when the mobile station is verified.

  • Patent number: 7302250
    Abstract: In the method of recognizing fraudulent emergency calls from a mobile station, a mobile station originating an emergency call is identified based on a mobile equipment identity received from the mobile station. A count of emergency calls received from the identified mobile station is generated and an incoming emergency call from the identified mobile station is determined as fraudulent based on the count.

  • Publication number: 20040203574
    Abstract: When a switch in a wireless network receives an emergency call from a mobile station lacking a unique identifier (a non-coded mobile station) assigned by a service provider, the switch stores the mobile equipment identity (MEID) of the mobile station in association with the default, non-unique identifier of the mobile station in a mapping table. The switch routes the emergency call to a Public Service Answering Point (PSAP) and sends an emergency routing number assigned to the switch as the calling party number. The switch also signals the MEID of the mobile station to the PSAP. If the emergency call drops, the PSAP performs a call back to the emergency routing number and supplies the MEID of the mobile station associated with the call back. The switch, upon receiving a call back using its emergency routing number, accesses the default mobile station identifier from the mapping table using the MEID, and pages the mobile station using the default mobile station identifier.
