Abstract
The disclosed system enables a wideband codec audio call between a mobile device and a wireless telecommunication network support center by ensuring that multiple components of the network participating in the call and multiple legs that make up the call all communicate using the same wideband codec. A leg among the multiple legs is a connection between two components participating in the call. While all the legs making up the call between the caller and the callee have to be wideband, the system can enable any branching legs in the call, for example, those directed to a third party, to be either wideband or narrowband.
Claims20
A method comprising:
- determining that a call associated with a communications network is directed to a communications network support center;
- creating a first leg of the call by receiving the call at a first component associated with the communications network,
- wherein the first leg operates in a wideband codec;
- creating a second leg of the call between the first component and an interactive voice response (IVR);
- determining, by the IVR, that a user equipment (UE) is requesting to communicate with an agent associated with the communications network;
- transferring the call from the IVR to the first component;
- and
- creating a third leg of the call by routing the call to the agent associated with the communications network,
- wherein the second leg of the call and the third leg of the call are branching legs, and
- wherein the third leg operates in the wideband codec while enabling the second leg to use a narrowband codec.
At least one non-transitory, computer-readable storage medium storing instructions which, when executed by at least one data processor of a system, cause the system to:
- determine, by a first component associated with a communications network, that a call is directed to a communications network support center;
- create a first leg of the call by routing the call to a second component associated with the communications network;
- create a second leg of the call by routing the call to an interactive voice response (IVR);
- determine that a user equipment (UE) is requesting to communicate with an agent associated with the communications network;
- transfer the call to the second component;
- create a third leg of the call by routing the call to the agent associated with the communications network,
- wherein the second leg of the call and the third leg of the call are branching legs;
- and
- establish a wideband codec audio communication associated with the first leg and the third leg of the call while enabling the second leg to use a narrowband codec audio communication,
- wherein the wideband codec audio communication uses a greater frequency range than a narrowband codec.
A method comprising:
- creating a first leg of a call by sending multiple packets of a call received from a mobile device to a mobile network core associated with a communications network;
- determining that the call is directed to a communications network support center;
- creating a second leg of the call by routing the call from the mobile network core to an Interconnect Session Border Controller (I-SBC) associated with the communications network,
- wherein the I-SBC is peered with a Session Border Controller (SBC);
- creating a third leg of the call by routing the call from the I-SBC to the SBC;
- creating a fourth leg of the call by routing the call from the SBC to a call routing platform;
- creating a fifth leg of the call by routing the call from the call routing platform to an interactive voice response (IVR);
- determining by the IVR that the mobile device is requesting to communicate with an agent associated with the communications network;
- transferring the call to the call routing platform;
- creating a sixth leg of the call by routing the call from the call routing platform to the agent associated with the communications network,
- wherein the fifth leg of the call and the sixth leg of the call are branching legs associated with the call routing platform;
- and
- establishing a wideband codec audio communication associated with the first leg, the second leg, the third leg, the fourth leg, and the sixth leg of the call, while enabling the fifth leg to use a narrowband codec audio communication,
- wherein the wideband codec audio communication uses a greater frequency range than a narrowband codec.
