Abstract: A method is provided for routing an emergency call. The method comprises receiving an emergency call and identifying an end node associated with the call. The end node may be a communications device involved in establishing the emergency call that is geographically near the originator of the emergency call. A look-up table is then accessed to identify the appropriate public safety answering point (PSAP) associated with the end node, and the emergency call is routed to the identified PSAP.

Abstract: The method for transferring data sends the data as part of first and second permanent identifiers during a communication procedure prior to establishing a traffic channel in the communication system. Besides the data, the first permanent identifier includes routing information to a home system forming part of the communication system. The second permanent identifier is an expanded permanent identifier with the data forming at least part of the expanded portion thereof. Based at least on recognizing a portion of the second permanent identifier, a home system sends the first and second permanent identifiers to a destination entity. The destination entity extracts the data from the first and second permanent identifiers. In this manner, a traffic channel does not need to be established to transmit the data.

Abstract: In the method of updating a unique call back number for a wireless unit having originated an emergency call, a unique call back number for the wireless unit is updated (e.g., changed or added to a list of unique call back numbers) based on a received unique call back number.

Abstract: In the method, a paging identifier for a wireless unit is obtained using a unique call back identifier for an emergency call placed by the wireless unit in response to an emergency call back. Then, an emergency intersystem page, which provides the paging identifier of the wireless unit and identifies the emergency intersystem page as requesting paging of the wireless unit for an emergency call back, is sent.

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.

Abstract: An emergency routing number (ELRN) is assigned to each switch in a wired communication network. When a switch of the wired communication network routes an emergency call to a Public Service Answering Point (PSAP), the switch sends the ELRN as the calling party number and provides the PSAP with a hardware identifier (HID). The HID identifies, at the switch, the landline connecting the switch to the wired phone initiating the emergency call. If the emergency call drops, the PSAP performs a call back using the ELRN as the called party number. The switch that routed the emergency call to the PSAP receives the call back. The PSAP also sends the HID to the switch. When a switch receives its ELRN as the called party number, the switch recognizes an emergency call back situation and routes the emergency call back on the landline identified by the HID.

Abstract: A method is provided for controllably migrating a wireless network from MIN based operation to IMSI based operation. The method comprises implementing changes that affect inter-network operations during a first phase of the migration. Remaining changes, including changes that affect intra-network operations are implemented during a second phase of the migration.

Abstract: A method for routing emergency calls is provided for emergency calls placed over a packet-switched network (310) from a Customer Premises Equipment (CPE) (110) at a remote location (100). The method includes: registering the CPE (110) with a home Internet Service Provider (ISP) (260) through a remote ISP (130) that is providing the CPE (110) access to the packet-switched network (310); determining that the CPE is at a remote location (100); obtaining a local Internet Protocol (IP) address that corresponds to a Public Safety Answering Point (PSAP) (170) serving the remote location (100); routing non-emergency calls to the home ISP (260) for call processing; and, handling emergency calls locally at the remote ISP (130) in accordance with the obtained local IP address.

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.

Abstract: The method for transferring data sends the data as part of the expanded portion of an expanded permanent identifier which is associated with an end user in a communication system. The expanded permanent identifier is sent along with another permanent identifier, also associated with the end user, during a communication procedure prior to establishing a traffic channel in the communication system. The other permanent identifier includes routing information to a home system forming part of the communication system. Based at least in part on recognizing the other permanent identifier, a home system sends at least the expanded permanent identifier to a destination entity. The destination entity extracts the data from the expanded permanent identifier. In this manner, a traffic channel does not need to be established to transmit the data.

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.

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.

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.

Abstract: An emergency routing number (ELRN) is assigned to each switch in a wired communication network. When a switch of the wired communication network routes an emergency call to a Public Service Answering Point (PSAP), the switch sends the ELRN as the calling party number and provides the PSAP with a hardware identifier (HID). The HID identifies, at the switch, the landline connecting the switch to the wired phone initiating the emergency call. If the emergency call drops, the PSAP performs a call back using the ELRN as the called party number. The switch that routed the emergency call to the PSAP receives the call back. The PSAP also sends the HID to the switch. When a switch receives its ELRN as the called party number, the switch recognizes an emergency call back situation and routes the emergency call back on the landline identified by the HID.

Abstract: The method for transferring data sends the data as part of a first permanent identifier associated with an end user in a communication system. The first permanent identifier is sent along with a second permanent identifier, also associated with the end user, during a communication procedure prior to establishing a traffic channel in the communication system. Besides the data, the first permanent identifier includes routing information to a home system forming part of the communication system. Based at least in part on recognizing the second permanent identifier, a home system sends at least the first permanent identifier to a destination entity. The destination entity extracts the data from the first permanent identifier. In this manner, a traffic channel does not need to be established to transmit the data.
