Method for guaranteeing HS-DSCH channel service quality and RNC

Abstract

A method for ensuring service quality of HS-DSCH channel includes measuring information characterizing state of channel jam, judging that HS-DSCH channel state is reached on jam threshold and special channel resource is greater that relevant well-to-do threshold according to measured information then switching over at least partial user to special channel.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for guaranteeing service quality of HS-DSCH channel and an RNC. Background technique [0002] HSDPA (High Speed ​​Downlink Packet Access) is a technology that provides high-speed downlink data services for multiple users, and is suitable for downloading large amounts of information services such as multimedia and the Internet. It adopts a series of key technologies such as adaptive modulation and coding (AMC), hybrid retransmission (HARQ), and fast scheduling of base stations to realize downlink high-speed data transmission. [0003] In WCDMA, HSDPA is an important technology. The physical layer uses key technologies such as AMC and HARQ to increase the rate. Among them, adaptive modulation and coding (AMC) technology makes full use of existing channel conditions for users close to Node-B. Use high-order modulation schemes and high coding rates to maximize downlink d...

Problems solved by technology

[0006] 1. The HS-DSCH channel carries too many Guaranteed Rate (GBR) users, and the scheduling frequency of each user decreases, resulting in low throughput of some GBR users with relatively low priority, and QoS has to be to guarantee

[0007] 2. The user is at the edge of the cell and the channel quality is poor. If the HS-DSCH downlink data scheduling algorithm reconsiders the weight of CQI is large, the downlink rate of this user must be low; if the weight of CQI in the scheduling algorithm is small, then The same downlink data consumes a lot of power, which also affects the rate of other users established on HS-DSCH

This solution only considers whether the service is suitable to be established on HS-DSCH from the perspective of traffic volume, without considering the impact of HSDPA resource congestion on users

[0009] Therefore, when the above two situations occur, the HS-DSCH channel will be congested, the actual downlink rate of the user will be reduced, the user experience will be affected, and the service quality of the HS-DSCH channel will be affected.
