Method of configuring time frequency resource between household base stations cooperatively and device of configuring time frequency resource between household base stations cooperatively

Abstract

The present invention discloses a method of configuring time frequency resource between household base stations cooperatively and a device of configuring the time frequency resource between the household base stations cooperatively, which are used for improve the reliability and the service quality of a network. The method comprises the steps of using a centralized management device to receive the time frequency resource distribution requests sent by the service household base stations, wherein the time frequency resource distribution requests are sent when the local pre-configured time frequency resources do not satisfy the user access demands, when the time frequency resources which are not used and can satisfy the user access demands are determined not to exist in the pre-configured time frequency resources of the adjacent household base stations, transferring the time frequency resources to the service household base stations orderly according to an order from small to large of the values of the time frequency resources distributed to and used by the users of the adjacent household base stations until the time frequency resources satisfy the user access demands, and compensating aiming at the rate loss of the transferred household base stations until all household base stations satisfy the data rate demands of the users. Therefore, a household base station wireless resource distribution conflict is solved in a local range cooperatively, the channel condition of the network is optimized, and the throughput, stability, reliability and service quality of the network are improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for cooperatively configuring time-frequency resources among home base stations. Background technique [0002] Femtocell is a kind of femtocell base station for residential or enterprise environment. cellular base station. Femtocells provide high-speed and high-bandwidth mobile data services for indoor users with fixed bandwidth and low power, which can reduce the capacity pressure and coverage requirements of macro base stations at a relatively low cost. [0003] Femtocells are currently mainly used in hotspot coverage scenarios. In an enterprise environment, a large number of femtocells are densely deployed and users access frequently, and it is easy to have a situation where the time-frequency resources that can be reused by femtocells cannot meet user needs. In particular, when the number of users served by the home base station is large,...

AI Technical Summary

Problems solved by technology

In an enterprise environment, a large number of femtocells are deployed intensively and users access frequently, and it is easy for the time-frequency resources that can be reused by femtocells to fail to meet user needs.

In particular, when the number of users served by the home base station is large, the possibility of causing local time-frequency resource allocation conflicts is even greater, and the reallocation of wireless time-frequency resources in the entire area is likely to cause serious communication delays even a loss of communication
