Access control method and device

Abstract

The invention discloses an access control method and device. The access control method is applied to mobile communication terminals. The access control method includes the first step of measuring the first signal quality of first signals from a mobile relay node and the second signal quality of second signals from a macro base station, the second step of transmitting instruction messages to the mobile relay node when the difference value between the first signal quality and the second signal quality is within a predetermined interval, enabling the mobile relay node to determine the first number of the mobile communication terminals within the predetermined interval where the corresponding difference value between the first signal quality and the second signal quality is located according to all the received instruction messages, and determining an access proportionality coefficient according to the number, and the third step of having access to access objects selected from the mobile relay node and the macro base station according to the access proportionality coefficient. Through the access control method and device, the communication quality is improved.

Description

technical field [0001] The invention relates to access technology, in particular to an access control method and device. Background technique [0002] The country's "Eleventh Five-Year Plan" has planned "four vertical and four horizontal" railway express passenger transport channels. It is estimated that by 2014, the mileage of high-speed railways above 250km / h in my country will reach 28,000 kilometers, and the maximum speed of trains can reach 380km / h. [0003] In LTE-A, the mobile relay node (MRN, Mobile Relay Node) is introduced on the high-speed train, by deploying one or more mobile relay nodes on the moving vehicle, and using it as a link between the users in the vehicle and the base stations along the way The data relay point uses the cooperation between the base station and MRN and the cooperation between MRN and users to achieve the purpose of improving coverage and system capacity, and provides wireless access services for group user terminals in the vehicle.

Problems solved by technology

[0007] In the process of train entry-stop-exit, the traffic demand of users in the train compartment is relatively large. Since all communications are carried out through UE-MRN-eNB at this time, it is difficult for the macro base station installed at the station to allocate A lot of resources are given to the MRN, which will lead to insufficient wireless backhaul links, resulting in a decline in user communication quality or even failure to communicate normally
