Abstract
Embodiments contemplate methods and systems that may route an emergency call from an enterprise user and/or a user in a private number plan, or an emergency call that may be initiated by a service on behalf of the user. Architectural extensions to the IMS emergency services architecture may allow an emergency call to be handled in a home network or a local network in which the user may be visiting (e.g., roaming) such that appropriate public safety systems may be apprised of the emergency communication.

Claim
1. A first device, the first device including a serving call session control function (S-CSCF) and the first device in communication with a communication network, the first device configured, at least in part, to:
receive a message indicative of an emergency from a second device, the second device including a proxy call session control function (P-CSCF), the message originated by a user from a wireless transmit/receive unit (WTRU) being operated within a jurisdiction of the communication network, the P-CSCF receiving the message from the WTRU;
forward the message to a third device, the third device including an emergency call session control function (E-CSCF) and the third device in communication with the communication network;
determine if at least a part of the message requires translation; and
translate the message to at least produce a publically identifiable form of a private number included in the message, the publically identifiable form of the private number providing a public identity of the WTRU, and to produce information about the user based on the private number.
2. The first device of claim 1, wherein the first device is further configured to establish at least one communication connection with the E-CSCF, the message forwarded to the E-CSCF via the at least one communication connection.
3. The first device of claim 1, wherein the first device is further configured to route the message to an application server (AS) upon the determination indicating at least a part of the message requires translation.
4. A first device, the first device in communication with a communication network, the first device including an application server (AS), and the first device configured, at least in part, to:
receive a message indicative of an emergency, the message forwarded from a second device, the second device including a proxy call session control function (P-CSCF), the message originated by a user from a wireless transmit/receive unit (WTRU) being operated within a jurisdiction of the communication network, the P-CSCF receiving the message from the WTRU;
identify the message as an emergency communication;
determine a requirement for translation of the identified emergency communication;
forward the identified emergency communication to a third device, the third device in communication with the communication network; and
translate the message to at least produce a publically identifiable form of a private number included in the message, the publically identifiable form of the private number providing a public identity of the WTRU, and to produce information about the user based on the private number.
5. The first device of claim 4, wherein the third device includes a serving call session control function (S-CSCF), the third device forwarding the emergency communication toward a public safety access point (PSAP).
6. A method performed by a first device, the first device in communication with a communication network, the method comprising:
receiving a message indicative of an emergency from a second device, the second device including a proxy call session control function (P-CSCF), the message originated by a user from a wireless transmit/receive unit (WTRU) being operated within a jurisdiction of the communication network, the P-CSCF receiving the message from the WTRU;
forwarding the message to a third device, the third device in communication with the communication network, wherein the first device includes a serving call session control function (S-CSCF) and the third device includes an emergency call session control function (E-CSCF);
determining if at least a part of the message requires translation;
translating the message to at least produce a publically identifiable form of a private number included in the message, the publically identifiable form of the private number providing a public identity of the WTRU, and to produce information about the user based on the private number;
establishing at least one communication connection with the E-CSCF; and
forwarding the message to the E-CSCF via the at least one communication connection.
