Come that the present invention will be described in detail below with reference to attached drawing and in conjunction with the embodiments.It should be noted that not conflicting
In the case of, the features in the embodiments and the embodiments of the present application can be combined with each other.
In view of carrier frequency that in the related technology can not be overlapping covered to multiple wireless networks carries out asking for Comprehensive Control
Topic present embodiments provides a kind of load being suitable for belonging to heterogeneous networks and the neighboring community with same covering or inclusion relation
Frequency control method.Fig. 1 is the flow chart of carrier frequency control method according to the ... of the embodiment of the present invention, as shown in Figure 1, this method includes such as
Lower step：
Step S102, controller obtain the load information of adjacent area, wherein cell where the controller is different from adjacent area ownership
Network and with covering or inclusion relation；
Step S104, above controller determine what needs controlled according to the load information of cell where controller and its adjacent area
Carrier frequency；
Step S106, above controller control the shutdown or unlatching of carrier frequency according to the networking types of carrier frequency.
The present embodiment is first obtained the load information of adjacent area, is then determined according to load information by the above method, controller
The carrier frequency controlled is needed, the shutdown or unlatching of carrier frequency are controlled further according to the networking types of carrier frequency, control can be considered in this way
Cell and the user of adjacent area and the distribution situation of business where device, so as to the load overlapping covered to multiple wireless networks
Frequency carries out Comprehensive Control.
For it is above-mentioned it is multiple have overlapping covered wireless network be 2/3G with covering networking when, above controller
The shutdown of carrier frequency is controlled according to the networking types of carrier frequency or unlatching includes：When above controller is the base station controller of 2G, if
