Hybrid access method and system based on partial resource sharing

Abstract

The invention relates to a hybrid access method based on partial resource sharing. The method comprises the following steps: browsing all available resources of each femtocell, and dividing all the available resources of each femtocell into public resources and private resources, which correspond to each femtocell; determining a femtocell base station subjected to candidate access, which correspond to accessed MUE (Micro User Equipment), and collecting and acquiring an MUE assembly which is subjected to candidate access and corresponds to each femtocell; and for each femtocell, selecting the MUE from the MUE assembly subjected to candidate access and accessed the selected MUE into the femtocell, and the accessed MUE and FUE (Femtocell User Equipment) accessed into the femtocell share the public resources of the femtocell. The invention also relates to a hybrid access system based on partial resource sharing. According to the invention, difference between PRBs (Physical Resource Blocks) is drawn into consideration, the available resources of the femtocell are divided into the public resources and the private resources. The MUE accessed into the femtocell can use the part of public resources, so that part of the MUE seriously interfered by the femtocell is accessed into the femtocell, the channel quality of the MUE is improved, accordingly, the throughput of the MUE is improved under the condition that the FUE throughput is ensured.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a hybrid access method and system based on partial resource sharing. Background technique [0002] With the continuous development of communication technology, from GSM to CDMA, to WCDMA, HSPA, LTE, from the 2G mobile communication system that can provide low-speed data and voice, to the LTE mobile communication system that can provide high-speed data services, the mobile communication system System capacity and service quality have been greatly improved. [0003] However, the evolution of communication technology, the expansion of services, and the change of user habits will also cause problems for the LTE system that can support high-speed services: [0004] 1. According to statistics from authoritative organizations, more than 50% of voice services and more than 70% of data services are carried out indoors. To increase indoor coverage, operators need to build ...

AI Technical Summary

Problems solved by technology

However, due to the limited wireless resources, adding outdoor base stations will not only cause great interference due to frequency sharing, but also directly building more macro base stations will greatly increase the cost of the system network (including equipment purchase, maintenance, and selection. Manpower consumed by the address)

[0005] 2. The frequency used by the current communication system is getting higher and higher. From the initial 800MHZ to the current 2GHZ, or even 4GHZ, the attenuation of the channel will also increase accordingly. Coupled with the loss caused by the wall, the indoor signal Poor quality, low user satisfaction

Since the channel quality of users on different resources is different, if the channel quality of FUE on resource A is better than that on resource B, but FUE cannot use resource A, the throughput of FUE will be greatly reduced
