Abstract

The embodiment of the invention relates to a method, a terminal, equipment and a system for realizing carrier load balance. The method for realizing carrier load balance comprises the following steps: a terminal maps on a reversed carrier through mapping algorithm within part or whole reversed carrier range; wherein the mapped reversed carrier corresponds to a plurality of forward carriers; and the terminal maps on one forward carrier among part or all the forward carriers through mapping algorithm within part or whole forward carrier range. Therefore, when a great amount of M2M applications or intelligent terminals use random access channels, each terminal maps on one of the reversed carriers through mapping algorithm; and since the mapping algorithm has uniformity or equal probability property, the amounts of terminals mapped by individual reversed carrier are close to one another or even the same, and the amounts of terminals initiating random switch-in on individual reversed carrier are close to one another or even the same, that is, the load among all the random access channels is balanced, and the load among all the reversed carriers is balanced.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, terminal, device and system for realizing carrier load balancing. Background technique [0002] In a wireless communication system, a terminal often adopts a contention-based random access method to achieve reverse access. Since the reverse access channel is a single shared channel, and each terminal device can randomly initiate the access process according to its own wishes, if two or more terminal devices send access information at the same time, the uplink of the air interface Signals will interfere with each other, causing the receiving end to fail to correctly identify each sending end signal. This situation is called random access collision. The way to solve the collision is to back off for a period of time and then initiate an access attempt until the access is successful or the maximum number of access attempts is reached. The occurrence...
