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.

Embodiment approach

[0066] 1. Measurement of user HS-DSCH channel quality CQI

[0067] Because the user established on the HS-DSCH needs to periodically report the channel quality indicator CQI to the NODEB through the uplink HS-DPCCH channel. Different CQI values ​​map different transmission block sizes and encoding methods, which represent the ability of the current user to receive receipts on the HS-DSCH channel. When NODEB schedules users on the HS-DSCH, it will examine the CQI value of each user. Low users are allocated less channel resources.

[0068] Since the CQI value will be periodically reported to the NodeB, the RNC can obtain relevant information by measuring the corresponding IUB port. Considering that the purpose of the RNC to measure the CQI is to determine whether the channel quality has deteriorated or improved, the measurement report can use hysteresis Refer to Figure 1 and Figure 2 for the method of reporting A and B events.

[0069] In Fig. 1, the time when the channel qual...

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...
