The invention provides a method for providing maximum transmission unit (MTU) length for a terminal, which comprises that: a packet switch gateway acquires the current terminal MTU length; the packet switch gateway provides the current terminal MTU length for the terminal and is used for transmitting a data packet through the terminal according to the current terminal MTU length. The invention also provides a packet switch gateway. In the invention, the packet switch gateway provides the current terminal MTU length for the terminal; therefore, the terminal can determine the current terminal MTU length and transmit the data packet according to the current terminal MTU length, the length of the data packet transmitted by the terminal is consistent with the terminal MTU length, and fragment and defragment of the data packet are voided in a packet switch bearing network. Therefore, the communication efficiency is improved.
Description
technical field [0001] The present invention relates to wireless communication technology, in particular to a method for providing a terminal with a maximum transmission unit (MTU, Maximum Transmission Unit) length and a packet switching (PS, Packet Switch) gateway (Gateway). Background technique [0002] With the development of communication technology, wireless communication bandwidth is gradually increasing. In order to support the rapid development of wireless bandwidth applications, operators put forward higher requirements for packet switching bearer networks, that is, to support large-capacity, high-performance throughput business processing. Moreover, with the diversification of packet services and terminal development, the length of data packets is also changing. For example, for peer-to-peer (P2P, peer-to-peer) services, the length of uplink data packets gradually increases. However, the IP-based packet switching bearer network has some inherent defects. For examp...
