Abstract
Systems and methods for facilitating inter-network handover of a communication with a call center are provided. In one example, a computer-implemented method includes: receiving, at a first network from a second network, information indicating a location of a user device, detecting, at the first network, presence or absence of an active connection between the user device and a call center designated to the first network, obtaining, at the first network, the location of the user device from the received information, in response to the detection of the presence of the active connection, and transmitting the information indicating the location to a location database in communication to the call center.
Claims20
A method for facilitating inter-network handover of a communication with a call center, the method being implemented by at least one electronic processor configured to execute computer programs, wherein the method comprises:
- receiving, at a first network from a second network, information indicating a location of a user device;
- detecting, at the first network, presence or absence of an active connection between the user device and the first network;
- obtaining, at the first network, the location of the user device from the received information, in response to the presence of the active connection;
- and
- transmitting the information indicating the location to a location database in communication to the call center.
A computer system for facilitating inter-network handover of a communication with a call center, the computer system comprising:
- a processor;
- and
- a computer-readable storage media storing computer-executable code that, when executed by the processor, causes the computer system to:
- receive, at a first network from a second network, information indicating a location of a user device;
- detect, at the first network, presence or absence of an active connection between the user device and the first network;
- obtain, at the first network, the location of the user device from the received information, in response to the detection of the presence of the active connection;
- and
- transmit the information indicating the location to a location database in communication to the call center.
A user device comprising:
- a processor;
- and
- a computer-readable storage media storing computer-executable code that, when executed by the processor, causes the user device to:
- generate information of the user device in response to an emergency call initiated by the user device, the information indicating a current location of the user device;
- generate a SIP message including the information indicating the current location of the user device;
- determine presence or absence of an active connection between the user device and a first network, the first network being associated with a call center;
- and
- in response to the presence of an active connection between the user device and a first network, transmit the SIP message to a first user plane function of the first network to allow the information included in the SIP message to be routed to the call center.
