Embodiment
Describe the present invention below in conjunction with accompanying drawing.
Fig. 1 is the cordless communication network schematic diagram according to a specific embodiment of the present invention.
For simplicity's sake, only show the four sub-district Q of switching equipment 1, first base station controller 2, second base station controller 3 and 2 controls of the first base station controller first sub-district A, the second sub-district B, the 3rd sub-district P and second base station controller 3 down under controlling among the figure.Should be appreciated that a switching equipment can have a plurality of subordinaties' network controller (for example base station controller), and each network controller can there be a plurality of subordinaties' sub-district.Wherein, the first sub-district A and the second sub-district B some be overlapping.Under many circumstances, equally also may there be overlapped situation between heterogeneous networks controller subordinate's the sub-district, as the 3rd sub-district P under first base station controller, 2 controls among the figure and the 4th sub-district Q under 3 controls of second base station controller.
Share control method if adopt cell load of the prior art, (promptly the first sub-district A is in overload state to suppose the load peak to have occurred by the first sub-district A, its the distributing radio resource summation exceed a first threshold), first base station controller 2 can be unusual by each sub-district under its linchpin being monitored the load of finding and only pay close attention to the first sub-district A, and the business of the edge customer among the first sub-district A (being arranged in and the user of other sub-district as the second sub-district B lap) is switched to the neighbor cell (for example second sub-district B) of the first sub-district A.The Target cell of this switching is all adjacent with the overload sub-district usually and lap arranged, this is when carrying out the business switching betwixt because of the subscriber equipment that is arranged in the lap of Target cell and overload sub-district, two serving BS subsystems before and after its transmitting power can guarantee to switch (for this subscriber equipment provides the base station sub-system of communication service, comprising a base station controller respectively) can both receive the enough strong upward signal from this subscriber equipment.
This shows that in the prior art, described professional switching controls process does not have the participation of the Radio Resource relevant information of Target cell, promptly first base station controller 2 is not known the load condition of the second sub-district B.Therefore, when the load condition of the second sub-district B had not allowed it to accept extra customer service, above-mentioned switching will be failed.
Why above-mentioned switching can fail, pay close attention to the first unusual sub-district A of load exactly because carry out first base station controller 2 of load sharing control, there is very big blindness in this controlling schemes for the selection of the Target cell (the second sub-district B as the aforementioned) that business is switched isolatedly.
And when adopting cell load provided by the invention to share control method, switching equipment 1 is known the load condition of all sub-districts under its subordinate's each BSC (comprising first base station controller 2 and the second base station controller 2) control, that is to say, it belongs to the resource indicator message (comprising the wireless resource information of each sub-district, such as the allocation of radio resources situation of sub-district etc.) of the BSC of its compass of competency from each that comprises first base station controller 2 by joint-detection.Thus, switching equipment 1 can know that not only the first sub-district A is in overload state, and the load condition that can also know the sub-district of which related with the first sub-district A (for example, adjacent with the first sub-district A) meets the condition as the customer service switching target small area.Like this, just can carry out intelligentized control, switch also no longer blindly cell load.Preferably, above-mentioned switching not only can occur between the same BSC control sub-district down, can also occur between the sub-district of different B SC under controlling.
Fig. 2 is for being used for the flow chart of a plurality of cell loads of joint-detection with the method for carrying out switching controls according to a specific embodiment of the present invention in the switching equipment of cordless communication network.Below in conjunction with Fig. 2 and with reference to Fig. 1 this method is described in detail.
