An upstream traffic reporting method, intermediate node, channel switching method and system

Abstract

The invention discloses a report uplink service quantity method, a middle node and channel switch method and a system; wherein, the channel switch method comprises that when the uplink service is established in a reinforced uplink special channel E-DCH, an uplink service quantity information is reported to a wireless network controller by a special measurement type or the uplink service quantity information is reported to the wireless network controller in an extension E-DCH channel data frame type, and the wireless network controller switches the E-DCH channel according to the uplink service quantity information. The invention can achieve the switch and bandwidth adjustment to the E-DCH channel according to the uplink service quantity information when the uplink service of the wireless network controller is established on the E-DCH channel, thus saving cell resource; furthermore, the invention can avoid channel error switch or bandwidth error adjustment caused by unknown service quantity, thus improving the stability of the service which is carried on the E-DCH channel.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for reporting uplink business volume, an intermediate node, a channel switching method and a system. Background technique [0002] For Wide-band Code Division Multiple Access (WCDMA) systems based on Release 99 or Release 4 standards, the uplink and downlink capacity of bearing services is relatively limited, theoretically no more than 2 Mbps. Moreover, the actual throughput rate of a single user is relatively low, and the maximum allowed transmission rate is usually 384Kbps. The actual transmission rate often cannot reach such a high rate, which is obviously insufficient for services that provide high-speed data services. [0003] In order to improve the uplink and downlink capacity and transmission rate of the system, the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) organization introduced the High Speed ​​Downlink Packet Access (H...

Problems solved by technology

However, the prior art can only realize judging the traffic volume of RACH, DCH, PCH or USCH (time division duplex mode only) transmission channel; that is to say, when user equipment (UE, User Equipment) uses E-DCH channel, the UE cannot report the actual uplink traffic carried on the logical channel of the E-DCH to the radio network controller (RNC, RadioNetwork Controller)

[0006] The above-mentioned prior art cannot satisfy the channel switching condition under the E-DCH because the uplink traffic volume of the E-DCH channel is not reported to the RNC. Traffic measurement for channel switching
