Abstract
At least one device receives a call request from a calling party to a called party. The device routes the call request to an Internet Protocol Multimedia Subsystem (IMS) core when a first condition is met and bypasses the IMS core when a second condition is met.
Claims16
A system comprising:
- at least one device to:
- receive a call request from a calling party to a called party,
- determine whether the calling party or the called party is served by an Internet Protocol Multimedia Subsystem (IMS) core,
- route the call request toward the called party, and bypassing the IMS core when the calling party and the called party are not served by the IMS core, and
- route the call request to the IMS core when the calling party is not served by the IMS core and the called party is served by the IMS core.

A method performed by a network device, the method comprising:
- receiving, by a communication interface of the network device, a call from a first party for a second party;
- determining, by a processor of the network device and based on receiving the call, whether the first party is served by an Internet Protocol Multimedia Subsystem (IMS) core;
- determining, by the processor of the network device and based on receiving the call, whether the second party is served by the IMS core;
- routing, by the communication interface, the call toward the second party and bypassing the IMS core when the first party and the second party are not served by the IMS core;
- and
- routing, by the communication interface, the call request to the IMS core when the first party is not served by the IMS core and the second party is served by the IMS core.
3 more elements
A system comprising:
- at least one device to:
- receive a call request from a calling party to a called party,
- neither the calling party nor the called party being an Internet Protocol Multimedia Subsystem (IMS) user,
- evaluate whether the calling party has invoked an IMS application,
- evaluate whether the called party has invoked an IMS application,
- route the call request to the IMS core when at least one of the calling party or the called party has invoked the IMS application,
- bypass the IMS core when the calling party and the called party have not invoked the IMS application,
- receive another call request,
- determine that the other call request is an emergency call request, and
- bypass an IMS core based on the other call request being the emergency call request.
