Abstract

The embodiment of the invention provides a method and a device for determining the maximum capacity of a message, so as to prevent an NP (Network Processor) in a base station from performing fragmentation and reassembly on the message and increase the transmission efficiency of the base station. The method comprises the following steps that the message sent by a sending end is received; when the received message is determined as a transmission control protocol (TCP) message containing a maximum segment size (MSS) value, the MSS value of the message is compared with a preset capacity threshold; if the MSS value of the message is greater than the preset capacity threshold, the MSS value of the message is adjusted to the preset capacity threshold; and the TCP message carrying the adjusted MSS value is sent to a receiving end.

Description

technical field

[0001] The present invention relates to the field of mobile communication, in particular to a method and device for determining the maximum capacity of a message Background technique

[0002] The MTU (Maximum Transform Unit, maximum transmission unit) of the NP (Network Processor, network processor) processor in the base station is 1500 bytes, that is, the byte size of the largest data packet that can pass is 1500 bytes.

[0003] Taking the uplink direction as an example, the IP (Internet Protocol, Internet Protocol) packet sent by UE (User Equipment, User Equipment) will add GTPU (GPRS Tunneling Protocol User, GPRS Tunneling Protocol User Surface) header (8 bytes) and UDP (User Datagram Packet, user datagram) / IP header (28 bytes) for internal communication of the base station, the MTU of each node inside the base station is 1500 bytes, so as long as the IP packet sent by the UE Processors larger than 1464 (1500-28-8) will fragment, send the fragmented packe...
