Embodiment
Hereinafter also describe in conjunction with the embodiments the present invention in detail with reference to accompanying drawing.Need to prove, in the situation that do not conflict, embodiment and the feature in embodiment in the application can make up mutually.
Consider in correlation technique and can't carry out to the overlapping covered carrier frequency of a plurality of wireless networks the problem of Comprehensive Control, the present embodiment provides a kind of carrier frequency control method that is applicable to belong to heterogeneous networks and has the neighbor cell of same covering or inclusion relation.Fig. 1 is that as shown in Figure 1, the method comprises the steps: according to the flow chart of the carrier frequency control method of the embodiment of the present invention
Step S102, controller obtain the load information of adjacent area, and wherein, this residential quarter, controller place and adjacent area belong to heterogeneous networks and have with covering or inclusion relation;
Step S104, above-mentioned controller determines according to the load information of residential quarter, controller place and its adjacent area the carrier frequency that needs are controlled;
Step S106, above-mentioned controller is according to shutoff or the unlatching of the networking Type Control carrier frequency of carrier frequency.
The present embodiment passes through said method, controller first obtains the load information of adjacent area, then determine according to load information the carrier frequency that needs are controlled, again according to shutoff or the unlatching of the networking Type Control carrier frequency of carrier frequency, can consider like this user of residential quarter, controller place and adjacent area and the distribution situation of business, thereby can carry out Comprehensive Control to the overlapping covered carrier frequency of a plurality of wireless networks.
A plurality of to have overlapping covered wireless network be 2/3G when covering networking for above-mentioned, above-mentioned controller comprises according to shutoff or the unlatching of the networking Type Control carrier frequency of carrier frequency: when above-mentioned controller is the base station controller of 2G, if the carrier frequency that needs to control is the 3G carrier frequency, base station controller by with the interface of the radio network controller of 3G, the notice radio network controller is controlled shutoff or the unlatching of carrier frequency; When above-mentioned controller is the radio network controller of 3G, if the carrier frequency of need controlling is the 2G carrier frequency, radio network controller by with the base station controller interface of 2G, the informing base station controller is controlled shutoff or the unlatching of carrier frequency.This method is practical.
When the same covering of 2/3G networking, utilize information interactive interface or standard I ur-g interface, share the cell information between different systems, and adjudicate according to the 2/3G cell information, determine the carrier frequency that finally need to close or open.Generally speaking, when above-mentioned controller was the single mode controller, interface was standard I ur-g interface; And when above-mentioned controller was multi-mode controller (Multi-mode Controler), interface can be information interactive interface or standard I ur-g interface, and the energy-saving and cost-reducing solution when covering networking for solution 2/3G is same has increased flexibility.Complete 2/3G with the information interaction that covers networking middle controller and neighboring interval by above-mentioned interface, convenient and easy.
A plurality of to have overlapping covered wireless network be 2/3G when covering networking for above-mentioned, and information interaction is carried out by interface in controller and adjacent area can comprise following dual mode:

At controller, carrier frequency (is for example saved energy and reduce the cost control, saving energy and reduce the cost during the same covering of 2/3G networking) time, can number of users or the cell load of load is less (for example, lower than the shutoff thresholding of setting) or greatly (for example, unlatching thresholding higher than setting) carrier frequency all turn-offs or opens, to realize the energy-saving and cost-reducing of same covering networking.But might once turn-off or open too much carrier frequency like this, thereby cause user's QoS to descend.In order to address the above problem, controller can be prescribed a time limit lower than the shutoff door of setting at number of users or the cell load of load when determining the carrier frequency that needs are controlled according to the load information of adjacent area, need to determine the carrier frequency of shutoff according to the shutoff dominance relation of setting; In like manner, prescribe a time limit higher than the door capable of being opened of setting at number of users or the cell load of load, determine the carrier frequency that to open according to the unlatching dominance relation of setting.By this method, controller can need determine the carrier frequency of shutoff or unlatching according to dominance relation, fully guarantee user's Qos, has also guaranteed Systems balanth simultaneously.
above-mentioned shutoff thresholding or unlatching thresholding can set manually, but for the thresholding of setting more accurate, can or open thresholding according to the shutoff thresholding of following setting parameter: residue equivalent user number, uplink control protocol (Transmission Control Protocol, referred to as TCP) power, downstream broadband receives gross power (Received Total Wideband Power, referred to as RTWP) disturb, the residential quarter uplink and downlink load, up-downgoing Channel Elements (Channel Element, be called for short CE), the code resource, residue transfer resource etc.Set in this way and turn-off or open thresholding, can reach the Qos that had both guaranteed the user, fully solve again the energy-saving and cost-reducing problem of operator.
Too frequent in order to prevent that system loading meeting in some cases from reducing suddenly the shutoff carrier frequency that causes, controller can be after the fixed time of the carrier frequency of determining to turn-off, again carrier frequency is turn-offed judgement, if twice court verdict is consistent, then carry out the shutoff of carrier frequency.Can improve Systems balanth in this way.
In order to guarantee Systems balanth under normal circumstances, the permission time period that a carrier frequency is controlled can be set, controller judges whether the current time was in the permission time period of controlling carrier frequency; If so, above-mentioned controller is according to shutoff or the unlatching of the networking Type Control carrier frequency of carrier frequency.
