Method and electronic apparatus for optimizing bandwidth utilization GTP-U data packet transmission

A source general packet radio service tunnelling protocol user (GTP-U) node for communication in a wireless network, the source GTP-U node comprising:

• memory storing instructions;
• and
• at least one processor,
• wherein the instructions, when executed by the at least one processor, cause the source GTP-U node to:
• receive at least one data packet from at least one user equipment (UE),
• determine whether the at least one received data packet is at least one guaranteed bit rate (GBR) data packet or at least one non-GBR data packet,
• if the at least one received data packet is the at least one GBR data packet, transmit the at least one received GBR data packet to at least one target GTP-U node,
• if the at least one received data packet is the at least one non-GBR data packet,
• store the at least one received non-GBR data packet into a buffer before transmitting to the at least one target GTP-U node, and
• transmit the at least one received non-GBR data packet to the at least one target GTP-U node based on a maximum segment size (MSS) of the buffer.

A non-transitory computer readable storage medium configured to store one or more computer programs including instructions that, when executed by at least one processor of a source general packet radio service tunnelling protocol user (GTP-U) node in a wireless network, cause the GTP-U node to perform operations comprising:

• receiving at least one data packet from at least one user equipment (UE),
• determining whether the at least one received data packet is at least one guaranteed bit rate (GBR) data packet or at least one non-GBR data packet,
• if the at least one received data packet is the at least one GBR data packet, transmitting the at least one received GBR data packet to at least one target GTP-U node,
• if the at least one received data packet is the at least one non-GBR data packet,
• storing the at least one received non-GBR data packet into a buffer before transmitting to the at least one target GTP-U node, and
• transmitting the at least one received non-GBR data packet to the at least one target GTP-U node based on a maximum segment size (MSS) of the buffer.
