Embodiment Construction

[0036] Combine below figure 1 The present invention is described in further detail. figure 1 middle,

[0037] Step 1: According to the requirement of inter-frequency measurement, the Universal Mobile Communication System Terrestrial Radio Access Network (UTRAN) needs to start the downlink compression mode.

[0038] Step 2: Set the service level of the UE according to different service categories of the UE, or different service level requirements of the UE. Generally speaking, those users who require high quality of service, or users who require a relatively fixed transmission rate, such as real-time services such as voice and video, are set to have a higher service level; while those who are not sensitive to changes in transmission rate, The services with high tolerance to service quality changes are set to lower service levels; different users can also be set to have different priority service levels according to the service level agreement that may be signed between the se...

Abstract

This invention relates to an optimization method for the down-link compression mode of WCDMA communication system, which sets the service levels of user terminals according to different service kinds or levels and sets different service level threshold values based on the network loads, if the load is high, then small amount of users at the highest level apply the compression mode method with half spread-spectrum factors, if the load is low, then most of the users are allowed to apply such method so as the distribute network resources reasonably.

Description

technical field [0001] The invention relates to a preferred method of the downlink compressed mode mode of wideband code division multiple access (WCDMA) communication system. Background technique [0002] In the existing cellular mobile communication system, in order to improve the utilization rate of spectrum resources, reduce the interference to the system, and increase the capacity of the system, the radio frequency power of the base station in the system is limited within a certain range, which not only meets the coverage needs of the cell, The interference to other cells is also reduced. When the mobile station leaves a cell and enters another cell, the signal of the original cell received by the mobile station must become weaker and weaker. When the signal quality drops to a certain threshold, no matter whether the power is increased or not, the communication quality of the link cannot be satisfied. . In order to maintain the communication quality without interrupti...
