Embodiment Construction

[0039] The basic thought of the present invention is: when IP layer transmits business message, compresses UDP header into UDP multiplex header, uses the business message with same source UDP port number and purpose UDP port number as multiplexing subframe, in this The front part of the multiplexing subframe is added with the UDP multiplexing header, and multiple multiplexing subframes carrying the UDP multiplexing header are encapsulated in the same IP packet, so that multiple service messages share the UDP header and the IP header , thereby improving transmission efficiency, reducing requirements on transmission bandwidth and operating costs.

[0040] In the present invention, the IP data packet header does not support optional items, and adopts fixed options, that is, figure 1 The optional fields shown are not used.

[0041] The realization of the header compression and multiplexing method in the present invention includes two parts: a control plane and a user plane, where...

Abstract

A method for realizing head compressing and multiplexing in IP layer includes compressing UDP head of IP data packet transmitted in IP layer to be UDP multiplexing head, using service message with thesame source UDP port number and destination port number as multiplexing sub frame and adding UDP multiplexing head at front part of multiplexing sub frame, packaging more than one of multiplexing subframes carried with UDP multiplexing head in one and the same IP packet, furthermore adding IP head on head of IP packet.

Description

technical field [0001] The invention relates to compression and multiplexing technology, in particular to a method for realizing header compression and multiplexing at the IP layer. Background technique [0002] In wireless communication systems, all-IP is a development trend. IP can use resources more efficiently, and the use of packet switching technology can achieve more sharing than the use of time slot switching technology, thereby reducing the cost of unit transmission. [0003] For example, in the CDMA2000 system, the IP / UDP protocol stack is used to carry services between the centralized base station controller (CBSC) and the centralized base transceiver station (CBTS), wherein each service channel uses a source user datagram The protocol (UDP) port number and the destination UDP port number are represented by a pair, plus the difference in IP address, different channels correspond to different {source IP address, source UDP port number, destination IP address, dest...
