Double-layer wireless access system and interlayer scheduling method

Abstract

The invention discloses an interlayer scheduling method, comprising the following steps: step S302, a wireless terminal measures the signal quality of a wireless contact of the first class and a wireless contact of the second class and reports the measured result to a communication treatment and control unit at a network side; step S304, according to the measured result, the communication treatment and control unit at the network side determines that whether the wireless terminal uses the wireless contact of the first class or the wireless contact of the second class. A double-layer wireless access system is also disclosed. The system which comprises the communication treatment and control unit is used for dynamically distributing a business channel of the wireless contact of the first class and a business channel of the wireless contact of the second class to the wireless terminal according to the measured result of the wireless terminal obtained from the measurement on the channel quality of the wireless contact of the first class and the wireless contact of the second class. The interlayer scheduling method achieves the optimized use of macro-cell wireless access resources and lowers requirements on covering quality and layout difficulty for micro-cell wireless access points.

Description

Technical field [0001] The present invention relates to the field of wireless communication, in particular to a two-layer wireless access system and an inter-layer scheduling method under a hierarchical cell architecture. Background technique [0002] The present invention mainly relates to the existing scheduling technology, the inter-layer switching technology of the existing hierarchical radio access network and the diversity technology based on the hierarchical radio access network. [0003] In the design of HSUPA (High-Speed ​​Uplink Packet Access) and HSDPA (High-Speed ​​Downlink Packet Access) of the 3G system, in order to use the diversity gain between users to improve the throughput of the cell, the scheduling technology implemented by the NodeB is adopted. The service based on NodeB scheduling is called the scheduling service, and the scheduling service is divided into the uplink scheduling service and the downlink scheduling service. In the implementation of the uplink...
