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
At least one non-transitory, computer-readable storage medium storing instructions to enable a wideband codec audio call between a mobile device and a wireless telecommunication network support center, which, when executed by at least one data processor of a system, cause the system to:
- create a first leg of a call by sending multiple packets from a received mobile device call to a mobile network core associated with a wireless telecommunication network;
- determine, by the mobile network core, that the call is directed to the wireless telecommunication network support center;
- create a second leg of the call by routing, by the mobile network core, the call to an Interconnect Session Border Controller (I-SBC) associated with the wireless telecommunication network,
- wherein the I-SBC is peered with a Session Border Controller (SBC);
- create a third leg of the call by routing the call, by the I-SBC, to the SBC;
- determine, by the SBC, that the call is directed to the wireless telecommunication network support center;
- create a fourth leg of the call by routing the call, by the SBC, to a call routing platform;
- create a fifth leg of the call by routing, by the call routing platform, the call to an interactive voice response (IVR);
- determine by the IVR that the mobile device is requesting to communicate with an agent associated with the wireless telecommunication network;
- transfer the call to the call routing platform;
- create a sixth leg of the call by routing, by the call routing platform, the call to the agent associated with the wireless telecommunication 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
- improve communication quality between the mobile device and the wireless telecommunication network by 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 a branching leg, 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.

A system comprising:
- at least one hardware processor;
- and
- at least one non-transitory memory storing instructions, which, when executed by the at least one hardware processor, cause the system to:
- determine, by a first component, that a call is directed to a wireless telecommunication network support center;
- create a first leg of the call by routing, by the first component, the call to a second component associated with a wireless telecommunication network;
- create a second leg of the call by routing, by the second component, the call to an IVR;
- determine by the IVR that a UE is requesting to communicate with an agent associated with the wireless telecommunication network;
- transfer the call to the second component;
- create a third leg of the call by routing, by the second component, the call to the agent associated with the wireless telecommunication 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 a branching leg, 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.
