Abstract

Methods and computing systems for dynamic rate adaption during real-time Long Term Evolution (LTE) communication are described. A real-time LTE communication session with another mobile device is established over an LTE connection. The real-time LTE communication session is established with codec rate. A monitor component receives data indicating a performance of the real-time LTE communication session, and causes the real-time LTE communication component to perform, during the real-time LTE communication session, a renegotiation of the codec rate based at least on the performance of the real-time LTE communication session.

First claim

1 . A mobile device, comprising:
at least one processor; a real-time Long Term Evolution (LTE) communication component executable by the at least one processor to establish a real-time communication session with another mobile device over a LTE connection, establishment of the real-time LTE communication session including establishing a codec rate for the real-time LTE communication session; and a monitor component executable by the at least one processor to receive data indicating a performance of the real-time LTE communication session, and to cause the real-time LTE communication component to perform, during the real-time LTE communication session, a renegotiation of the codec rate based at least on the performance of the real-time LTE communication session.

2 . The mobile device of claim 1 , wherein the real-time LTE communication session is a Voice over LTE (VoLTE) connection.

3 . The mobile device of claim 1 , wherein the data includes one or more data packets carrying real-time LTE communication data, and wherein the monitor component is further executable to:
determine, from the one or more data packets, at least one performance indicator associated with the real-time LTE communication session; and determine to cause the renegotiation of the codec rate based at least on the at least one performance indicator.

4 . The mobile device of claim 3 , wherein the at least one performance indicator includes one or more of packet jitter information, packet delay information, or packet loss information.

5 . The mobile device of claim 1 , wherein the data includes a message received by the mobile device from a base station requesting to change the codec rate, and wherein the monitor component is further executable to cause the renegotiation of the codec rate based at least on the at least one performance indicator.

6 . The mobile device of claim 1 , wherein the data includes a message received from a base station, the message indicating a media access control (MAC) reconfiguration, and wherein the monitor component is further executable to cause the renegotiation of the codec rate based at least on the MAC reconfiguration.

7 . The mobile device of claim 6 , wherein the MAC reconfiguration includes a change to an error correction or error detection configuration.

8 . The mobile device of claim 6 , wherein the MAC reconfiguration includes a change from a less robust to a more robust error correction or error detection configuration.

9 . The mobile device of claim 6 , wherein the MAC reconfiguration includes a change to Hybrid automatic repeat request (HARQ) Transmission Time Interval (TTI) bundling.

10 . A method, comprising:
establishing, by a mobile device via a Long Term Evolution (LTE) connection, a real-time LTE communication connection between the mobile device and another mobile device, the real-time LTE communication connection having a codec rate; receiving, by a monitor component of the mobile device, data indicating a performance of the real-time LTE communication connection; and causing the mobile device to renegotiate the codec rate based at least on the data.

11 . The method of claim 10 , wherein the real-time LTE communication connection is a Voice over LTE (VoLTE) connection.

12 . The method of claim 10 , wherein the data includes one or more data packets including real-time LTE communication data associated with the real-time LTE communication connection, and the method further comprises:
determining at least one performance indicator associated with the real-time LTE communication connection; and determining to cause the mobile device to renegotiate the codec rate based at least on the at least one performance indicator.

13 . The method of claim 12 , wherein the at least one performance indicator includes at least one of jitter information, delay information, or packet loss information for the real-time LTE communication connection.

14 . The method of claim 10 , further comprising:
wherein the data includes an indication from a modem of the mobile device that the mobile station received, from the base station, a media access control (MAC) layer message indicating a MAC layer reconfiguration; and causing the mobile device to renegotiate the codec rate based at least on receipt of the MAC layer message.

15 . The method of claim 14 , wherein the MAC reconfiguration includes a change to an error correction or error detection configuration.

16 . The method of claim 14 , wherein the MAC reconfiguration includes a change from a less robust to a more robust error correction or error detection configuration.

17 . The method of claim 14 , wherein the MAC reconfiguration includes a change to Hybrid automatic repeat request (HARQ) Transmission Time Interval (TTI) bundling.

18 . One or more non-transitory computer-readable media including instructions executable by at least one processor of a computing device to cause the computing device to:
establish, via a Long Term Evolution (LTE) connection, a Voice Over LTE (VoLTE) connection to another computing device, the VoLTE connection having a codec rate; monitor one or more communications received by the computing device; determine a performance of the real-time LTE communication connection based at least on the one or more communications; and cause the computing device to renegotiate the codec rate for the real-time LTE communication connection based at least on the performance.

19 . The one or more non-transitory computer-readable media of claim 18 , wherein the one or more communications includes a message from a base station to the computing device that indicates a MAC layer error correction configuration, and the instructions are further executable by the at least one processor of the computing device to determine to cause the computing device to renegotiate the codec rate based at least on the message.

20 . The one or more non-transitory computer-readable media of claim 18 , wherein the data includes a plurality of packets of the VoLTE connection, and the instructions are further executable by the at least one processor of the computing device to:
cause the computing device to determine one or more performance indicators of the VoLTE connection from the plurality of packets of the VoLTE connection, the performance indicators including one or more of a packet jitter, a packet delay, or a packet data; and determine to cause the computing device to renegotiate the codec rate based at least on the one or more performance indicators.
