Abstract

The present invention provides an access network network architecture, the network architecture includes: a radio spectrum sensor front-end RFE and a virtual spectrum pool, the RFE communicates with the virtual spectrum pool through an SP interface; wherein the virtual spectrum pool : Based on various wireless communication standards, use cloud computing to dynamically generate corresponding spectrum information entity files and IQ baseband waveform data modulated by each spectrum carrier, and send each spectrum information and IQ baseband waveform data modulated by each spectrum carrier through the SP interface In the RFE; the RFE: used to adjust its own operating parameters to the required state according to the received spectrum information entity files of each frequency band; and adjust the received IQ basebands according to the adjusted operating parameters Waveform data is used to configure spectrum environment parameters.

Description

technical field [0001] The invention belongs to the technical field of network communication, and in particular relates to an access network architecture. Background technique [0002] With the continuous growth of smart terminal users, the transmission volume of mobile data has been continuously increased. Therefore, in order to meet the ever-increasing user demands, mobile network operators have to increase network capacity. The spectrum efficiency of the fourth-generation mobile communication Long Term Evolution (LTE, Long Term Evolution) standard is close to the Shannon limit. The most prominent method to increase network capacity is to create a heterogeneous and complex structure by adding more cells. Microcell Networks (HetSNets) or by implementing technologies such as Multiple-Input Multiple-Output (MIMO, Multiple-Input Multiple-Out-put), and Massive MIMO, on multiple antennas / on frequency resources at the same time / simultaneously services to increase the number of ...
