Dynamic VoLTE Allocation (DVA)

A non-transitory computer-readable medium containing instructions for determining a voice encoding codec which, when executed, cause the system to perform steps comprising:

• discovering a packet header size used in a session using a Silence Insertion Descriptor (SID);
• inspecting downlink packet sizes coming into a receive buffer;
• determining when three consecutive packet sizes are greater than zero, then setting a first factor, a second factor, and a third factor equal to zero;
• calculating a header size;
• and
• determining a voice encoding codec by subtracting a header overhead value from the packet size,
• wherein the first factor comprises a current voice encoding codec size;
• the second factor comprises a header overhead;
• and a third factor comprises a Candidate SID.

A system for determining a Voice over LTE (VOLTE) codec comprising:

• a processor;
• a radio access network interface in communication with the processor;
• and
• a memory, the memory communicatively coupled with the processor, the memory further comprising instructions that, when executed by the processor, cause the processor to:
• discover a packet header size used in a session used a Silence Insertion Descriptor (SID);
• inspect downlink packet sizes coming into a receive buffer;
• determine when three consecutive packet sizes are greater than zero, then set a first factor, a second factor, and a third factor equal to zero;
• calculating a header size;
• and
• determining a voice encoding codec by subtracting a header overhead value from the packet size,
• wherein the first factor comprises a current voice encoding codec Packet size;
• the second factor comprises a HeaderOverHead;
• and a third factor comprises a Candidate SID.
