User access mechanism based on loads

Abstract

The invention relates to a user access mechanism based on loads and belongs to the field of mobile communication. The mechanism comprises the steps that a user measures RSRP (Reference Signal Receiving Power) of base stations around the user, then the practical RSRP of the base stations around the user is predicted, and the base stations of which RSRP prediction values are greater than a certain threshold value form a candidate base station set; SINRs (Signal to Interference plus Noise Ratios) of various candidate base stations in the set are estimated, utility function values between the user and the candidate base stations are calculated according to the estimated SINRs and the load condition of each base station, and the calculated utility function values are sorted in a descending order; and finally the user accesses the suitable base station with the maximum utility function value. According to the mechanism, the user accesses the suitable base station according to the real signal condition of the user and the loads, and under the condition of ensuring a bit error rate of the user, the access time delay of the user is minimized, and the loads in a network are balanced.

Description

technical field [0001] The invention belongs to the technical field of mobile communication and relates to a load-based user access mechanism. Background technique [0002] With the increasing popularity of the new generation of intelligent mobile communication terminals and the continuous emergence of new services, especially large-scale real-time 3D game services and high-definition video services, users' demand for mobile data traffic is getting higher and higher. 1000 times the challenge of explosive growth in data traffic. In order to meet this challenge, the number of small base stations in the network increases accordingly, and a dense heterogeneous network emerges as the times require. A dense heterogeneous network is a dense network architecture that deploys small base stations (such as micro, pico, and femto) on a large scale for network expansion in network hotspot areas or network blind spots for network coverage blind spots under the basic coverage of macro bas...

Problems solved by technology

However, the existing user access mechanism based on RSRP or SINR often causes users to access the base station with the largest RSRP or SINR in the surrounding area, resulting in more unbalanced load on the network, and eventually causing users to often fail to access the network or connect to the network. The input delay is unacceptable

[0003] Existing user access technologies are based solely on RSRP or SINR, without considering the load of the base station at the same time

Moreover, the existing user access technology ignores the influence of the user's movement and the surrounding environment on RSRP measurement when measuring the RSRP of the surrounding base stations, which cannot truly reflect the real RSRP situation of the surrounding base stations
