Problems solved by technology

At the same time, according to the current limitation of the 3GPP protocol, each TTI and each logical channel can only have one MAC-es PDU, so under the current protocol processing method, the processing performance of the transport layer will be greatly affected when the upstream traffic is large.

Embodiment Construction

[0026] Below in conjunction with accompanying drawing, the present invention will be described in further detail:

[0027] Process 1: Signaling processing----RNC needs to configure the IP bearer MTU corresponding to the wireless link during the establishment of the wireless link (including wireless link establishment, wireless link reconfiguration, and wireless link addition). After the transport layer protocol is used as the basic default setting.

[0028] Process 2: NodeB MAC-e data segmentation - the present invention adds the data segmentation function in the NodeB MAC-e entity, the UEMAC-e entity does not change, and performs interface changes for NodeB MAC-e and RNC MAC-es ; for the current handling of agreements, see figure 1 , MAC-e extracts DDI and N and forms Iub port data packet with MAC-es PDU to send, and the length of the data packet may exceed the MTU. Improvement methods such as figure 2 As shown, after the NodeB MAC-e entity receives the physical layer upl...

Abstract

The invention discloses a realization method for improving the transmission performance of UTRAN HSUPA IP in a WCDMA system. The processing performance on a transmission layer is greatly influenced under the circumstance of uplink large flow rate in the protocol processing mode at present. In order to solve the problem, the invention comprises the following steps: firstly, a base station MAC-e entity sectionally sends an uplink data package with length larger than the length of a maximum transmission unit to a wireless network controller; secondly, the MAC-es entity of the wireless network controller regroups the received uplink data package sent by the MAC-e entity into an uplink data package to be sent to a MAC-d entity. The invention improves the processing performance of the system under the circumstance of large flow rate; and then the realization is relatively simple; in addition, the method proposed by the invention is provided with the expandability of the larger flow rate of aUu port data in future.

Description

technical field [0001] The invention relates to a method for realizing IP transmission performance improvement of UTRAN HSUPA (Universal Terrestrial Radio Access Network High Speed ​​Uplink Packet Access Service) in a WCDMA system. Background technique [0002] 3GPP is in constant evolution and changes, constantly introducing new requirements to achieve low cost and high performance. Introduced IP transmission in 3GPPR5, the version is IP V4, and will adopt IP V6 gradually in the future; Introduced HSUPA in 3GPP R6. Under the current development trend, the combination of HSUPA and IP transmission is inevitable. [0003] In the IP transmission mode, when the size of high-level data exceeds the maximum transmission unit (MTU), the sending end will segment the data packet, and the receiving end will reassemble the data packet and send it to the high-level layer. In the Ethernet connection mode, the MTU is determined through negotiation between the two parties, and the length ...
