Method to implement E911 services in IMS (IP Multimedia Subsystem)
First Claim
1. A system, comprising:
- a memory to store computer-executable instructions; and
a processor, communicatively coupled to the memory, that facilitates execution of the computer-executable instructions to perform operations, comprising;
determining a change in an internet protocol address of a user equipment based on registration data received from the user equipment during a connection of the user equipment to a communication network, in response to determining that the interne protocol address does not match a home internet protocol address associated with the user equipment, comparing the internet protocol address with a set of internet protocol addresses associated with a set of respective tenant locations, wherein the user equipment is subscribed to a business account associated with the set of respective tenant locations, determining that the user equipment is located at a tenant location of the set of respective tenant locations in response to a determination that the internet protocol address matches a first internet protocol address of the set of internet protocol addresses, and in response to the determining that the user equipment is located at the tenant location, updating profile data associated with the user equipment, including assigning a temporary telephone number to the user equipment, wherein the temporary telephone number includes a predefined telephone number assigned to the tenant location, assigning an emergency services routing number to the user equipment, and assigning a location routing functionality indicator to the user equipment, wherein the profile data is utilized to facilitate a routing of an emergency call, received from the user equipment, to a public safety answering point device, wherein the operations further comprise;
determining that the user equipment is nomadic in response to a determination that the internet protocol address does not match the home internet protocol address and the set of internet protocol addresses, and in response to the determining that the user equipment is nomadic;
assigning a null value to the temporary telephone number and the emergency services routing number, and assigning a value to the location routing functionality indicator indicative that a location routing function device is to be queried subsequent to receiving the emergency call.

Abstract
A system and method that facilitates processing and/or routing of emergency call in an IMS (IP Multimedia Subsystem) for VoIP (Voice over IP) subscribers is provided. Specifically, an E911 profile is generated, for example, by an application server, for each VoIP subscriber based in part on current location information associated with the subscriber, such as, the subscriber'"'"'s IP address. The E911 profile is pushed to the HSS (Home Subscriber Server) of the IMS. The E911 profile can then be stored in the HSS and can be queried by an E-CSCF (Emergency Call Session Control Function) during emergency call processing. Moreover, when an emergency call is received from the subscriber, the E-CSCF can retrieve the E911 profile associated with the subscriber from the HSS and route the call to an appropriate PSAP (Public Safety Answering Point) based on an analysis of the information in the E911 profile.

10. A method, comprising:
-
determining, by a system comprising a processor, a change in an internet protocol address of a user equipment based on registration data received from the user equipment during registration of the user equipment with a communication network; subsequent to determining that the internet protocol address does not match a home internet protocol address associated with the user equipment, determining, by the system, that the user equipment is located at a tenant location in response to the internet protocol address being determined to match a first internet protocol address of a set of internet protocol addresses associated with a set of respective tenant locations including the tenant location, wherein the user equipment is subscribed to a business account associated with the set of respective tenant locations; in response to the determining that the user equipment is located at a tenant location, generating, by the system, profile data for the user equipment including; assigning a temporary telephone number to the user equipment, wherein the temporary telephone number includes a predefined telephone number assigned to the tenant location, assigning an emergency services routing number to the user equipment, and assigning a location routing functionality indicator to the user equipment; and directing, by the system, profile data to a data store within the communication network, wherein the profile data is utilized to facilitate routing an emergency call, received from the user equipment, to a public safety answering point device. - View Dependent Claims (11, 12, 13)

14. A method, comprising:
-
in response to determining that an emergency call is received from a user equipment receiving, by a system comprising a processor, profile data of the user equipment from a data store within a communication network, wherein the profile data is generated by an application server based on determining that an internet protocol address associated with the user equipment, received during registration of the user equipment with the communication network, does not match a home internet protocol address associated with the user equipment and based on determining that the internet protocol address matches a first internet protocol address of a set of internet protocol addresses associated with a set of respective tenant locations that are associated with a business account subscribed to by the user equipment; analyzing, by the system, the profile data to determine a predefined telephone number associated with a tenant location of the respective tenant locations; and facilitating, by the system, routing of the emergency call based in part on the analyzing, including employing the predefined telephone number as a temporary telephone number to facilitate emergency call processing. - View Dependent Claims (15)
