Problems solved by technology
In this way, the channel condition of user UE1 may be very poor, resulting in call drop, or even failure to work.
The power allocation method in the existing LTE (Long Term Evolution, Long Term Evolution) protocol cannot solve the downlink interference problem in the above situation because it cannot perform power control through the neighbor cell interference reported by the user or the signal quality of the own cell.

Embodiment Construction
[0038] In the embodiment of the present invention, the first base station receives signal information of the first base station reported by a non-CSG terminal in an idle state, and performs power self-optimization according to the received signal information of the first base station. Since the first base station can adjust parameters according to reports from terminals not in its own cell, interference to terminals near the first base station but not in a cell managed by the first base station is reduced, and channel quality of these terminals is improved.
[0039] Wherein, the first base station in the embodiment of the present invention is a base station of a type that only allows access by subscribed terminals or authorized terminals, such as a home base station in a closed mode;
[0040] The second base station in the embodiment of the present invention is a base station that is open to all terminals, such as a macro base station, a hybrid mode home base station, or an ope...

The invention relates to the wireless communication technical field, in particular to a power self-optimizing method, a system and a device, which aims at solving the problems of the prior art that a first base station only can adjust parameters according to a report from a second base station or a report which remains on a member terminal in the local region to cause strong interference on terminals which are neighboring to the first base station but do not belong to the local region. The power self-optimizing method comprises the following steps that: the first base station receives signal information of the first base station reported by a non-community-service-grant (CSG) terminal staying at an idle state; and power self-optimization is processed for the first base station according to the received signal information of the first base station. Since the first base station can adjust the parameters according to the report of the terminal which does not belong to the local region, the interference on the terminal which is neighboring to the first base station and does not belong to the local region can be reduced, the channel quality of the terminals can be improved, and the cutting off rate of the terminals can be reduced.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a power self-optimizing method, system and equipment. Background technique [0002] It is an urgent requirement of communication operators to reduce the complexity of operation management and reduce operation and maintenance costs. In the next-generation network, it is hoped that by introducing the network self-organization mechanism, manual participation in network planning and operation and maintenance will be reduced, and network construction and operation costs will be reduced. It is against this background that the SON (Self Organizing Networks, self-organizing network) feature of the E-UTRA (Evolved UMTS Terrestrial Radio Access, Evolved Universal Mobile Telecommunications System Terrestrial Radio Access) system has become a 3GPP (3rd Generation Partnership Project, 3rd Generation Mobile Communications Standardization Organization) a work topic for r...
