Method for accessing mobile station to base station and device thereof

Abstract

The invention relates a method for accessing a mobile station to a base station and a device thereof. The method comprises the steps that an alternative access vector from the mobile station to the base station is calculated according to a transmission channel from the mobile station to the base station; any two of a transmitting power vector of the mobile station, an access indication vector of the mobile station and a Lagrange vector are respectively fixed and another vector is updated on the basis of the alternative access vector, service quality of the mobile station and noise of the base station; when one round of updating of the transmitting power vector, the access indication vector and the Lagrange vector is completed, whether difference of the transmitting power vector, the access indication vector and the Lagrange vector obtained via recent two rounds of updating is less than a preset threshold is judged; and the difference is less than the preset threshold, the mobile station is accessed to the corresponding base station according to the transmitting power vector, the access indication vector and the alternative access vector obtained according to the latest round of updating.

Description

technical field [0001] The present invention relates to the field of mobile access technology, in particular to a method and device for connecting a mobile station to a base station. [0002] Background technique [0003] In modern wireless communication networks, users are often covered by multiple base stations at the same time. Each base station has different capacity and load status, and users can choose one or more base stations to access. At this time, the overall communication performance of the network not only depends on the power of each base station and the transmit / receive beam of each link, but also should be related to the access relationship between each user and the base station. [0004] Existing methods for connecting mobile stations to base stations only consider the fairness of users, that is, guarantee the quality of service of all mobile stations, but do not consider the fairness of base station loads. Using the existing method is likely to make most ...

AI Technical Summary

Problems solved by technology

Using the existing method is likely to make most of the mobile stations concentrated access to one or a few base stations, while other base stations have no mobile station access, which is extremely unfavorable for alleviating network congestion and ensuring network balance

In addition, in the existing method, in order to insist on connecting some mobile stations to the base station according to the pre-specified quality of service, all mobile stations cannot normally access the base station.
