Embodiment Construction

[0071] During packet transmission, QoS is used to measure the transmission delay and packet loss probability of packet data packets. Compared with the total number of connected users in the cell, the service quality information of the connected users can more accurately reflect the current resource usage and load status of the cell. If the quality of service of connected users has dropped to a considerable extent, even if the number of users in the cell is small, it is not appropriate to connect new users to share limited wireless resources.

[0072] On the basis of the prior art, in the present invention, before allocating resources for the HSDPA user requesting access, the detection of the service quality status of the cell is added to determine whether to access the user. Based on a predetermined judgment criterion, if it is considered that the user access causes the service quality loss of the connected user, the user access is denied; otherwise, the user access is allowed...

Abstract

The utility model discloses a user access method of the HSDPA system, which is as follows: the service quality state in a district is detected based on the service quality information of connected users in the district required for access by HSDPA users; if the service quality state in the district meets the access qualification, HSDPA resources are allotted to the users requiring for access; otherwise, the users are rejected to access. The utility model adopts the indicators such as time delay and the data quantity in postpositional memory zones that are directly related to the service quality of data users as the criterion for user access, and can finish part of the judgment work by Node B to reduce the burden of RNC. The utility model reduces packet loss rate while ensuring the service quality of the users, and improves the user satisfaction degree.

Description

technical field [0001] The present invention relates to HSDPA (High Speed ​​Downlink Packet Access, High Speed ​​Downlink Packet Access) technology, in particular to a user access method in the HSDPA system and a communication device applied by the method. Background technique [0002] In order to meet the needs of the rapid growth of wireless data services, the 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) R5 specification introduces the HSDPA technology. HSDPA greatly improves the peak rate of downlink data by adopting technologies such as AMC (Adaptive Modulation Coding, Adaptive Modulation Coding), HARQ (Hybrid Automatic Repeat Request, Hybrid Automatic Repeat Request), and high-order modulation. [0003] In the HSDPA system, wireless resources are shared by multiple users. The new features of HSDPA put forward higher requirements on the rationality of the radio resource management strategy, especially the call access control strategy. ...
