Comparing to 2G and 3G network

the superiority of LTE network is that it provides higher data transmission speed. As users increase in one LTE cell

the speed for a single user will decrease

for the sharing strategy of radio resources. When the number of users reaches or exceeds the system capacity which is permitted

it may cause the situation that some users cannot access to the LTE network. As for the KPI of success rate of LTE RRC connection establishment

the number of access failures will be accumulated

which causes the low success rate and bad user experience quality. This paper presents a solution on avoiding failures of RRC connection establishment

in the situation with a large number of users. The research focus on the methods of load balance on inter band frequencies

access strategy and parameters of massive capacity situation.
