CALL PROCESSING METHOD AND APPARATUS FOR USE IN LTE SYSTEM |
摘要 |
A method for performing robust header compression (ROHC) of request for comments (RFC) 3095 over a packet data convergence protocol (PDCP) layer to compress and decompress voice over long term evolution (VoLTE) packets is provided. In the voice call operation, an evolved node B (eNB) receives an initialization and refresh (IR) packet transmitted by a user equipment (UE) and performs ROHC compression/decompression on the voice packet with a compressed header based on the information contained in the received IR packet. If the IR packet is lost, the eNB cannot establish the context for the voice packet, resulting in ROHC operation failure and a call drop problem. In order to maintain the voice call, the eNB sends the UE a static negative acknowledgement (SNACK) when a voice packet is received in the state where no context exists. |
