Referring to fig. 1, a flowchart of a method for network optimization according to an embodiment of the present invention includes:
s102, setting configuration parameters of base stations, including setting configuration parameters of other base stations except a group of base stations to be upgraded, so that the other base stations cover the area covered by the group of base stations to be upgraded, and thus providing services for terminals in the area covered by the group of base stations to be upgraded, wherein the group of base stations to be upgraded comprises at least one base station;
setting configuration parameters of the group of base stations to be upgraded so that the group of base stations to be upgraded do not provide services for the terminal;
in the embodiment of the present invention, there are two configuration parameters of the base station: the configuration parameters of the upgrade state are the configuration of the base station in the upgrade process, that is, the configuration parameters set by the base station in the above embodiment during upgrade, and the configuration parameters of the service state refer to the configuration parameters before the upgrade of the base station and the configuration parameters after the upgrade is completed.
Optionally, in this embodiment of the present invention, the configuration parameter of the base station includes one of the following information or any combination thereof: pilot power, transmit antenna angle, pilot channel, transmit channel, etc. of the base station.
In this embodiment, there are many options for setting configuration parameters of other base stations except for a group of base stations to be upgraded, and preferably, configuration parameters of base stations adjacent to the group of base stations to be upgraded may be set, and of course, configuration parameters of other base stations except for base stations adjacent to the group of base stations to be upgraded may also be set as long as the set base station can cover the coverage area of the group of base stations to be upgraded. There are also many ways to set configuration parameters, for example, increasing the pilot power of the base station adjacent to the group of base stations to be upgraded, or decreasing the antenna tilt angle of the base station adjacent to the group of base stations to be upgraded, so that the coverage area of the base station adjacent to the group of base stations to be upgraded is enlarged, and services can be provided to the terminals within the coverage area of the group of base stations to be upgraded; for example, the group of base stations to be upgraded can be further deleted from the neighbor cell lists of other base stations, so that the terminal cannot be switched to the base station to be upgraded during switching, and service interruption cannot occur.
Optionally, the setting of the configuration parameters of the group of base stations to be upgraded may be: blocking the group of base stations to be upgraded; the blocking means that the base station does not provide services to the terminal, and a common technical means is to close a power amplifier of the base station and the like. Or the pilot channels of the group of base stations to be upgraded are closed.
Optionally, the base stations other than the group of base stations to be upgraded provide services to the terminal within the coverage of the group of base stations to be upgraded, and may only provide basic services, such as a voice service and a short message service, or may provide all services, which is specifically determined by a policy of an operator.
And S104, upgrading the group of base stations to be upgraded.
According to the method provided by the embodiment of the invention, the configuration parameters of other base stations except the base station to be upgraded are set, so that the other base stations except the base station to be upgraded can cover the terminals in the coverage range of the base station to be upgraded, and the terminals are provided with services through the other base stations except the base station to be upgraded, therefore, when the base station to be upgraded is upgraded, the services cannot be interrupted to the terminals, and the problems in the prior art are solved.

The following describes the upgrading process of the A group base station in detail:
There are many ways of setting up, for example: setting configuration parameters of an alpha sector of a base station 3, and covering the alpha sector of the base station 1; there are many methods for setting the configuration parameters of the α sector of the base station 3, for example: the pilot power of the base station 3 may be increased to a size that can cover the α sector of the base station 1. For another example: the antenna tilt angle of the base station 3 is reduced to the size of the α sector capable of covering the base station 1, and how to increase the pilot power of the base station and how to reduce the antenna tilt angle of the base station belong to the technologies known by those skilled in the art, and are not described herein again.

In addition to the above setting, optionally, a neighbor list of the base stations 3, 4, 5, 6, 7, 8 may be set, the base station 1 is deleted from the neighbor list of the base stations 3, 4, the base station 2 is deleted from the neighbor list of the base stations 4, 5, the base station 9 is deleted from the neighbor list of the base stations 6, 7, and the base station 10 is deleted from the base stations 7, 8; after the setting, if the terminal is switched among all the base stations, the terminal is not switched to the A group base station to be upgraded, and service interruption is not caused.
