Access grade control method

Abstract

The invention discloses a control method of access class, which includes the following steps: A. setting up M overload classes, each of which includes N access class groups, wherein, M and N are natural numbers; B. judging overload class m of a cell with overload and start the function of 'access class alternate prohibit' under the overload class, i.e. alternately setting up all access classes inall access class groups under the overload class m as 'prohibited' in broadcast information of the cell, wherein, m is integer and m is larger than and equal to 0 but less than M. The invention reduces the cell load, saves network resources of a wireless network controller, with the advantages of effective cell access user number reduction, fairness and shortly prohibited access of users on each access class, by prohibiting the access of all access class users alternately in the overload cell.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for controlling the access level of users in TD-SCDMA (Time Division Synchronous Code Division Multiple Access) wireless cell users. Background technique [0002] In various wireless access technologies, the geographical area covered is generally divided into a number of cells independently controlled by signals, which are managed relatively independently. In the wireless access technology, the most precious thing is the frequency resource. Experts and scholars try their best to increase the utilization rate of the frequency resource, but it is always limited. In the TD-SCDMA system, it is a self-interference system. If there are too many users to be connected, not only the frequency point (code channel) resources will be limited, but also the service quality of the connected users will be degraded due to self-interference, and even the As a result, the i...

Problems solved by technology

[0020] The disadvantage of the above method is that some mobile stations get "unfair" treatment, and some mobile stations may not be able to access the system all the time

If you want to solve this problem, you can periodically change the values ​​of C0~C9 in the cell, for example, at intervals of five minutes, alternately allow mobile stations with odd and even access levels to access, but network operators must participate in it, and Feedback of system load status is difficult
