Abstract
Systems and method are contemplated herein for method for making or facilitating a call routing decision associated with a call (e.g., a voice call, a video call). A TAS may receive the invite message and request location information associated with a mobile-terminating UE (MT-UE) from a subscriber network function (NF). The TAS may receive the location information from the subscriber NF. Based on the location information, the TAS may determine the call routing decision. The call routing decision may include one of routing the invite message to a first domain, routing the invite message to a second domain, redirecting the invite message, or rejecting the invite message.

A method for making a call routing decision associated with a call, the method comprising:
- receiving, at a telephone application server (TAS), an invite message associated with the call;
- requesting location information associated with a mobile-terminating UE (MT-UE) from a subscriber network function (NF);
- receiving the location information from the subscriber NF;
- determining, based on the location information, the call routing decision, wherein the call routing decision comprises one of:
- routing the invite message to a first domain, routing the invite message to a second domain, redirecting the invite message, or rejecting the invite message;
- and
- routing, based on the call routing decision, the invite message.
A method for facilitating a call routing decision associated with a call, the method comprising:
- receiving, at a subscriber network function (NF), a request for location information and subscriber information associated with a mobile-terminating UE (MT-UE) from a telephone application server (TAS);

- receiving the location information from the mobility NF;
- and
- communicating the location information and the subscriber information to the telephone application server, wherein the TAS makes the call routing decision based on the location information and the subscriber information.
A system for making a call routing decision associated with a call, the system comprising:
- one or more computer-processing components configured to execute operations comprising:
- receiving, at a telephone application server (TAS), an invite message associated with the call;
- requesting location information associated with a mobile-terminating UE (MT-UE) from a subscriber network function (NF);
- receiving the location information from the subscriber NF;
- determining, based on the location information, the call routing decision, wherein the call routing decision comprises one of:
- routing the invite message to a first domain or routing the invite message to a second domain;
- and
- routing, based on the call routing decision, the invite message.
