Embodiment Construction

[0043] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0044] figure 2 It is a schematic diagram showing the structure of a two-layer wireless access system according to the present invention. Refer to figure 2 , The two-layer wireless access system according to the present invention includes a first-type wireless contact 202, a second-type wireless contact 204, and a wireless terminal 206. The system also includes: a communication processing and control unit 208, which is configured to respond according to the wireless terminal The channel quality of the first-type wireless contacts 202 and the second-type wireless contacts 204 are measured to obtain the measurement results to dynamically allocate the service channels of the first-type wireless contacts 202 and the second-type wireless contacts 204 to wireless terminals.

[0045] The first type of wireless contact 202 covers the second type of wireless c...

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...
