Summary of the invention
Main purpose of the present invention is to provide a kind of changing method of wireless communication apparatus, causes the consumption of power supply to avoid wireless communication apparatus constantly to switch between the close network of binary signal intensity.
In order to achieve the above object, the step of changing method of the present invention comprises:
First step: wireless communication apparatus is being set up under the situation about linking with first base station of first network, receives second network signal that send second base station of second network; Wherein first network is third generation mobile technology (3rd-generation; 3G) network, second network are (Wireless fidelity; Wifi) network;
Second step: compare the intensity of first network signal and second network signal, and calculate the intensity difference of first network signal and second network signal, obtain first difference value;
Third step: whether judge first difference value greater than a switching predetermined value, if first difference value is then carried out next step greater than switching predetermined value, otherwise, then repeat second step;
The 4th step: after a scheduled time slot, compare the intensity of first network signal and second network signal again, and calculate the intensity difference of first network signal and second network signal, obtain second difference value;
The 5th step: whether judge this second difference value greater than this switching predetermined value, if second difference value is then carried out next step, otherwise then repeated second step greater than switching predetermined value;
The 6th step: the wireless communication apparatus handover network is linked in the stronger network of network signal.
Wherein, after finishing second step, this wireless communication apparatus also comprises the distance of carrying out between base stations detected and the wireless communication apparatus.The nearest base station of chosen distance wireless communication apparatus therefrom, and switch with it, each base station can be dispatched effectively thus.
In addition, after finishing the 5th step, this wireless communication apparatus also comprises the distance of carrying out between base stations detected and the wireless communication apparatus, and therefrom the nearest base station of chosen distance wireless communication apparatus is logined with nearest base station.
The purpose of above-mentioned steps is to select the nearest base station of network signal than persistent erection, thus, just can dispatch each base station effectively, makes network performance maximum efficiency.
By the present invention, the phenomenon that radio network device does not in the past stop handover network can be improved, radio network device can be avoided because do not stop handover network and cause the unnecessary consumption of battery electric quantity, further, properly each base station of scheduling effectively utilizes Internet resources.
Embodiment
See also Fig. 2 A, a wireless communication apparatus 2, it has the function of wireless Internet access, the also wireless network in the surveyed area automatically, and can login wireless network for user's online.These wireless communication apparatus 2 residing positions can receive the first network signal S1 and the second network signal S2 simultaneously, and suppose that this radio communication number device and first network signal S1 foundation link.
Wherein this first network is third generation mobile technology (3rd-generation; 3G) network, this second network is (Wireless fidelity; Wifi) network.
At this moment, wireless communication apparatus 2 desires are selected the stronger network signal of an intensity among two network signals, switch login, and changing method is as described below in detail:
See also Fig. 3, it is the changing method flow chart of wireless communication apparatus 2 of the present invention, and its step comprises:
Judge that whether the first difference value Δ 1 switches preset value delta v greater than one,, then get back to step S102, if the first difference value Δ 1 when switching preset value delta v, then carries out next step (S103) if when this first difference value Δ 1 switches preset value delta v less than this.
Obtain the location information of at least the first base station 31, and from these first base stations 31, select from the first nearest base station 31b of wireless communication apparatus 2, and obtain at least the second base station 41 positional informations, and therefrom select the second base station 41b (S106) nearest apart from wireless communication apparatus 2.
Compare the intensity of the first network signal S1 and the second network signal S2, and calculate the intensity difference of the first network signal S1 and the second network signal S2, obtain the second difference value Δ 2 (S107).
Relatively the second difference value Δ 2 and switching preset value delta v size less than switching preset value delta v, are then got back to step S102 as if the second difference value Δ 2; If the second difference value Δ 2 then carries out next step (S108) greater than switching preset value delta v.
The mentioned stronger network of network signal intensity among the step S109, S107 relatively obtains according to step, wherein, when wireless communication apparatus 2 is desired to switch, the network that this network signal intensity is stronger has at least one base station that handed over service can be provided, wireless communication apparatus 2 will utilize selected base station among the step S106 this moment, login.
The mentioned base station position information of obtaining utilizes global positioning system (GlobalPositioning System among the step S106; GPS) or arrive at time-of-arrival loaction (Time Difference of Arrival; TDOA) or Received Signal Strength Indicator; RSSI positioning modes etc. obtain these base station locations.
Further please cooperate Fig. 2 B, for example, when wireless communication apparatus 2 is in the first network signal S1 intensity stronger following time of situation, then, carries out network and switch by the nearest first base station 31b login of distance wireless communication apparatus 2; When wireless communication apparatus 2 is in the second network signal S2 intensity stronger following time of situation, then by the nearest second base station 41b login of distance wireless communication apparatus 2.
As above-mentioned explanation, this method makes wireless communication apparatus 2 can obtain the stable of T time, and in the time, wireless communication apparatus 2 can not be not intended to the free burial ground for the destitute handover network at T, saves the battery electric quantity of wireless communication apparatus 2.
In addition, can also make wireless communication apparatus 2 before handover network, do further and confirm, set and switch preset value delta v, purpose is to guarantee the intensity of two wireless networks, has difference to a certain degree, make wireless communication apparatus 2 switch to heterogeneous networks after, the user can obviously experience the lifting of network efficiency, guarantees that each switching all is significant.
Further, the present invention can optimize the use of network, has allocated the dispatching between the base station efficiently.
By the above-mentioned embodiment of the invention as can be known, the value on the true tool industry of the present invention.Above embodiment explanation only is preferred embodiment explanation of the present invention, has in all affiliated technical fields to know that usually the knowledgeable is when doing other all improvement and variation according to the above embodiment of the present invention explanation.Yet all improvement and variation that these are done according to the embodiment of the invention are in the claim that still belongs to invention spirit of the present invention and define.
