ENHANCED CAPABILITIES AND EFFICIENT BANDWIDTH UTILIZATION FOR ISSI-BASED PUSH-TO-TALK OVER LTE
First Claim
1. A computer-implemented method of transmitting supplemental information in IMBE blocks in a transport network, the method comprising:
- identifying an IMBE voice block requiring fewer than a full allocation of octets and therefore having unused octets;
revising a frame type identifier associated with the identified block to identify the block as an enhanced IMBE block;
selecting some of the unused octets to act as a control fieldassigning values to some of the control field to identify a parameter type;
assigning values to some of the control field to indicate that appended data is one of;
the first data segment of the parameter, the last data segment of the parameter, or an intermediate data segment of the parameter;
assigning values to other octets of the unused octets according to the parameter value and metadata describing aspects of the parameter value, thereby completing the assembly of an enhanced IMBE block; and
transmitting the enhanced IMBE block.

Abstract
For voice traffic over-the-air in LTE, persistent schedule (PS) or semi-persistent (SPS) scheduling would be the preferred method as they minimize signaling messages. In PS or SPS, resources are pre-allocated to the UE 402 at regular intervals (e.g., every 20 milliseconds). At each time slot, the UE will generally transmit an IMBE frames which are encoded in ISSI packet. In ISSI, other data streams are multiplexed with the IMBE frame and thus the packet size varies depending on its position within a super-frame. For PS or SPS, eNodeB must allocated sufficient resources to support the largest packet that. Therefore, there is spare capacity when the packet is not of the largest size. The exemplary embodiments specify ways to use spare capacity to transfer data.
