Access processing method and device, and communication system

Abstract

The invention provides an access processing method and device and a communication system. The method comprises the following steps: determining user equipment to be accessed according to the receiving strength of a pilot signal which is received by each first user equipment in a Macro Cell layer and is emitted by a base station in the Macro Cell layer and a preset threshold value corresponding to the first user equipment, and determining an SC-AP (Small Cell Access Point) to be accessed according to the quantity of second user equipment currently serving at each SC-AP in a Small Cell layer and the upper limit value corresponding to each SC-AP; determining reference user equipment in the second user equipment under each SC-AP to be accessed respectively according to the SINR (Signal to Interference plus Noise Ratio) on each PRB (Physical Resource Block) of each second user equipment under each SC-AP to be accessed; determining an SC-AP to be accessed corresponding to each user equipment to be accessed, and determining PRBs occupied by assess of the user equipment to be accessed to the corresponding SC-AP to be accessed according to the SINR of the reference user equipment at the SC-AP to be accessed on each PRB; accessing each user equipment to be accessed to corresponding SC-AP to be accessed according to the determined PRBs respectively.

Description

technical field [0001] The present invention relates to communication technology, in particular to an access processing method and device and a communication system. Background technique [0002] At present, building a three-dimensional layered network is the main way for operators to cope with the sudden increase in data traffic in the future, increase system capacity, and improve user experience. in, figure 1 It is a schematic diagram of the structure of the three-dimensional layered network in the prior art, such as figure 1 As shown, the three-dimensional layered network mainly includes: a macro cellular network layer (also called a Macro Cell layer) 11 and a micro base station (Small Cell) layer 12 . Specifically, the macrocellular network layer 11 mainly includes base stations (also called eNBs) 111, which are respectively connected to the MME and S-GW in the core network, and communicate with user equipment; the Small Cell layer 12 is mainly used to implement data s...

[0004] However, the open method cannot guarantee the interests of the authorized user equipment in the Small Cell layer 12 (which can be called a micro user (Small User; SU for short)), that is, the MU connected to the Small Cell layer 12 will occupy the resources of the SU; the closed The two schemes in the hybrid scheme cannot be connected to the Small Cell layer 12, so the throughput of the MU cannot be improved; in the two schemes of the hybrid scheme, the multi-level open access scheme causes all resources to be shared by the SU and the accessed MU. Accessed MUs and SUs compete for resources and damage the interests of SUs; the hybrid access scheme with limited shared resources only limits a fixed number of downlink resources for the accessed MUs, so it cannot effectively improve spectrum utilization. And the business needs of MUs that cannot keep some access
