Problems solved by technology

[0003] During the research and practice of the prior art, the inventors of the present invention found that, usually, the distance between the user and the base station before the migration is relatively short, and the distance between the user and the base station after the migration is relatively far, resulting in that the signal quality of the user after the migration is lower than that before the migration.

Embodiment Construction

[0020] Embodiments of the present invention provide a load balancing method, a base station, and a communication system. Each will be described in detail below.

[0021] see figure 1 , an embodiment of the load balancing method in the embodiment of the present invention includes:

[0022] 101. The first base station acquires resources to be provided by the first base station and remaining resources when a new user accesses;

[0023] For ease of description, in the embodiments of the present invention, the first base station is also referred to as a serving base station; the foregoing resources may be subchannel resources, bandwidth resources, or other scheduling resources.

[0024] The resources that need to be provided are the resources required by the service of the currently newly accessed user. The serving base station can obtain the service quality (QoS, Quality of Service) parameters of the user from the core network side when a new user accesses, for example, the max...

Abstract

The embodiment of the invention relates to the communication technique, and discloses a load balancing method and a base station. The load balancing method comprises the following steps of: acquiring resources to be provided and residual resources at the local end; judging whether the difference of the residual resources and the resources to be provided is less than the preset first resource threshold or not, and if so, transmitting bandwidth borrowing request information to a second base station; receiving the bandwidth borrowing request information transmitted by the second base station, wherein the information carries the loaning frequency spectrum of the second station; and scheduling a user to the loan frequency spectrum. The embodiment of the invention also provides a relevant base station and a communication system. The embodiment of the invention can realize that a user does not need to be migrated under the condition of the insufficient resources of the service base station, also ensure the business service quality of the service base station for the user and avoid the problem that the load balancing method in the prior art has poor service quality due to the migration of the user.

Description

technical field [0001] The invention relates to the technical field of communications, and in particular to a load balancing method and a base station. Background technique [0002] The principle of load balancing in existing communication systems is to migrate users from base stations with high load to base stations with low load. For example, when a new user enters the network, if the remaining resources of the base station are less than the resources that need to be newly provided for the new user, the base station will migrate the new user to a neighboring base station with low load. [0003] During the research and practice of the prior art, the inventors of the present invention found that, usually, the distance between the user and the base station before the migration is relatively short, and the distance between the user and the base station after the migration is relatively far, resulting in that the signal quality of the user after the migration is lower than that...
