Abstract
A wireless access node to facilitate voice over long term evolution (VoLTE) communication sessions comprises a wireless communication transceiver and a processing system. The wireless communication transceiver is configured to exchange VoLTE packets with a wireless communication device during a VoLTE communication session, and receive a scheduling request and responsively issue a scheduling grant with a number of hybrid automatic repeat requests (HARQs). The processing system is configured to calculate a quality of service (QoS) score based on a communication quality of the VoLTE communication session after issuing the scheduling grant, and if the QoS score falls below a threshold value, apply a lower level of fragmentation to the VoLTE packets.
Claims14
A method of operating a wireless access node to facilitate Voice over Long Term Evolution (VoLTE) communication sessions, the method comprising:
- exchanging VoLTE packets with a wireless communication device during a VoLTE communication session;
- receiving a scheduling request and responsively issuing a scheduling grant with a number of hybrid automatic repeat requests (HARQs);
- calculating a quality of service (QoS) score based on a communication quality of the VoLTE communication session after issuing the scheduling grant;
- when the QoS score falls below a threshold value, applying a higher level of fragmentation to the VoLTE packets, and
- when the higher level of fragmentation applied to the VoLTE packets reaches a predetermined highest level, then increase the number of HARQs by one which reaches a maximum number of HARQs.
A wireless access node to facilitate Voice over Long Term Evolution (VoLTE) communication sessions, the wireless access node comprising:
- a wireless communication transceiver configured to exchange VoLTE packets with a wireless communication device during a VoLTE communication session, and receive a scheduling request and responsively issue a scheduling grant with a number of hybrid automatic repeat requests (HARQs);
- and
- processing circuitry configured to calculate a quality of service (QoS) score based on a communication quality of the VoLTE communication session after issuing the scheduling grant, when the QoS score falls below a threshold value, apply a higher level of fragmentation to the VoLTE packets, and when the higher level of fragmentation applied to the VoLTE packets reaches a predetermined highest level, then increase the number of HARQs by one which reaches a maximum number of HARQs.
A computer apparatus to facilitate Voice over Long Term Evolution (VoLTE) communication sessions, the apparatus comprising:
- one or more computer readable storage media;
- circuitry;
- software instructions stored on the one or more computer readable storage media to operate the VoLTE communication session that, when executed by circuitry, direct a wireless access node to exchange VoLTE packets with a wireless communication device during a VoLTE communication session;
- receive a scheduling request and responsively issue a scheduling grant with a number of hybrid automatic repeat requests (HARQs), calculate a quality of service (QoS) score based on a communication quality of the VoLTE communication session after issuing the scheduling grant, when the QoS score falls below a threshold value, apply a higher level of fragmentation to the VoLTE packets, and when the higher level of fragmentation applied to the VoLTE packets reaches a predetermined highest level, then increase the number of HARQs by one which reaches a maximum number of HARQs.
