Decision method
The first embodiment
Fig. 2 is the schematic flow sheet of the first embodiment of decision method of the present invention.Below with reference to shown in Figure 2, describe the embodiment of present embodiment in detail.
At first, at step S21A, judge that the terminal present position accessed the first wireless network locates the signal strength signal intensity of the first wireless network and whether satisfy the first switching condition, if the signal strength signal intensity of the first wireless network does not satisfy the first switching condition, judge that then terminal continues to communicate by the first wireless network.
The signal strength signal intensity of wireless network is the primary factor of reflection radio link quality, wireless network signal is the space radiofrequency signal, very easily be interfered, therefore, whether carry out the most important condition that network switches with wireless network signal strength as the judgement terminal, terminal is in the situation that accesses the first wireless network, whether the signal strength signal intensity of judging first wireless network at place, terminal present position satisfies the first switching condition, if signal strength signal intensity does not satisfy the first switching condition, judge that then terminal continues to communicate by the first wireless network.
In some cases, for example, when the first wireless network is WLAN (wireless local area network), accessed in terminal in the situation of the first wireless network, tended to continue as far as possible to use the first wireless network to communicate.And very weak and when reaching the first switching condition that presets when the signal strength signal intensity of the first wireless network, begin to judge whether to switch or follow-up determining step.Therefore, can be that the signal strength signal intensity of the first wireless network is less than a predefined first threshold take the signal strength signal intensity of the first wireless network as the first switching condition of judging object.For example, set first threshold and be-75dbm, accessed in terminal in the situation of the first wireless network, judge signal strength signal intensity satisfied the first switching condition whether of locating the first wireless network in the terminal present position, judge that namely this signal strength signal intensity is whether less than-75dbm.If signal strength signal intensity shows then that more than or equal to-75dbm the signal(l)ing condition of present the first wireless network still is in good state, judge that then terminal continues to communicate by the first wireless network.
Signal strength signal intensity for the first wireless network, also can set the first different switching conditions, for example, according to the different requirements of zones of different user to the first wireless network connective stability, for arranging one, first threshold adjusts coefficient, use different adjustment coefficients for different customer requirements, with first threshold and the product of adjusting coefficient object as a comparison, the first corresponding switching condition is that the signal strength signal intensity of the first wireless network is located less than aforementioned product in the terminal present position.
During specific implementation, the signal strength signal intensity of the first wireless network can be the signal strength signal intensity of first wireless network at the current time terminal present position place judged.In addition, the mean value of considering signal strength signal intensity more can reflect the overall condition of wireless network signal quality in current slot, therefore, another kind of preferred implementation is to adopt average signal strength, for example, in the certain hour section before the moment that employing is judged, the average signal strength of first wireless network at place, terminal present position.Under this implementation, the first switching condition can be the certain-length time period before this is judged, namely the mean value of signal strength signal intensity of the first wireless network is located less than first threshold in interior terminal present position of the second time period.
At step S23, when satisfied first switching condition of signal strength signal intensity of the first wireless network is located in the terminal present position, judgement before carrying out this step S23 in the very first time section switching times of terminal between the first wireless network and second wireless network whether satisfy the second switching condition, if switching times does not satisfy the second switching condition, judge that then terminal continues to communicate by the first wireless network, if switching times satisfies the second switching condition, judge that then terminal switches to second wireless network from the first wireless network.
When satisfying in the situation of the first switching condition in signal strength signal intensity, consider the actual conditions of network, also need to judge further to determine whether terminal is carried out network and switched.For example, edge zone two kinds of network coverage area, the perhaps signal strength signal intensity of two kinds of networks all in the very weak situation in a certain period, may all satisfy the first switching condition by two kinds of network strengths this moment, if restrictedly not judged terminal switches, the repeatedly switching of terminal between two kinds of networks then may occur, namely the pingpang handoff phenomenon may occur.Therefore, by judging before this whether the switching times of terminal between the first wireless network and second wireless network satisfies the second switching condition in the very first time section, if switching times does not satisfy the second switching condition, then terminal continues to communicate by the first wireless network, thereby can reduce the appearance of pingpang handoff phenomenon.If switching times satisfies the second switching condition, high-frequency repeatedly switching does not namely occur, judge that then terminal switches to second wireless network from the first wireless network.
When terminal is repeatedly switched at short notice, be that switching times is when reaching a certain quantity, namely may occur or be about to occur the pingpang handoff phenomenon, therefore, can set the second switching condition is that the interior switching times of terminal between the first wireless network and second wireless network of very first time section is less than Second Threshold.When the switching times that has occured during greater than this Second Threshold, even the signal strength signal intensity of network satisfies the first switching condition, judge that terminal also no longer switches, thereby reduce the generation of pingpang handoff phenomenon.
For the switching times of terminal between two kinds of networks, can also set the second different switching conditions.For example, for arranging one, Second Threshold adjusts coefficient, network condition according to reality changes the adjustment coefficient, take Second Threshold and the product of adjusting coefficient as comparison other, the second corresponding switching condition can for the switching times of terminal between the first wireless network and second wireless network in the very first time section before carrying out this step S23 less than with aforementioned product.
The second embodiment
In the above-described embodiments, adopt the signal strength signal intensity of wireless network as the factor of at first judging before switching.Yet, wireless channel has specific than the channel fading of high bit-error, complexity and network equipment noise etc., these factors are so that the ability of signal strength signal intensity reflection link-quality is very limited, and by judging the connectedness between terminal and the wireless network, then can obtain more accurately whether to carry out the judgement that network switches, avoid after terminal switches factor owing to the wireless network connectivity wireless network after causing switching to use, thereby again switch.Referring to shown in Figure 3, introduce second embodiment of the inventive method.To further increase in the present embodiment the judgement to the connectedness between terminal and the wireless network, further reduce the generation of pingpang handoff phenomenon between rete mirabile.
At first, at step S31A, judge that the terminal present position accessed the first wireless network locates the signal strength signal intensity of the first wireless network and whether satisfy the first switching condition, if this signal strength signal intensity does not satisfy the first switching condition, judge that then terminal continues to communicate by the first wireless network.
This step and abovementioned steps S21A are similar, referring to the introduction of abovementioned steps S21A, no longer describe in detail here.
At step S31B, when satisfied first switching condition of signal strength signal intensity of the first wireless network is located in the terminal present position, judge whether this signal strength signal intensity satisfies the 3rd switching condition, if this signal strength signal intensity satisfies the 3rd switching condition, execution in step S33 then, otherwise execution in step S32.
The execution sequence that should be understood that above-mentioned steps S31B and S31A also can be put upside down, and judges whether first to satisfy the 3rd switching condition, is judging whether to satisfy the first switching condition.Perhaps, also can judge whether simultaneously to satisfy the first switching condition and the 3rd switching condition.
The signal strength signal intensity of the first wireless network being located in the terminal present position by step S31A does not satisfy the situation of the first switching condition and judges, on the contrary, also judges simultaneously and satisfies situation about switching this moment.Yet, the situation that satisfies the first switching condition for signal strength signal intensity may still comprise a wider scope, therefore, can also do further judgement according to network signal intensity, namely set the 3rd switching condition, judge that the terminal present position locates the signal strength signal intensity of the first wireless network and whether satisfy the 3rd switching condition, if signal strength signal intensity satisfies the 3rd switching condition, judge that then terminal carries out network and switch.The purpose of setting the 3rd switching condition is, the signal strength signal intensity of the first wireless network necessarily can't be satisfied terminal continue situation about using, and whether necessarily can't satisfy the situation that terminal continues to use with the signal strength signal intensity that still can not affirm the first wireless network and distinguish.For the former, then make the judgement of switching, and for the latter, owing to still can not affirm, need to carry out making again the judgement of whether switching after the judgement of next step network connectivty.
Specifically, can set the 3rd switching condition and be the signal strength signal intensity of terminal present position the first wireless network less than the 3rd threshold value, the 3rd threshold value is less than the first threshold among the step S31A.Take above-mentioned first threshold as-75dbm is as example, the 3rd threshold value can be-80dbm.By setting the 3rd threshold value and the judgement of using the 3rd switching condition, the situation weak to the first wireless network signal strength namely less than the situation of the 3rd threshold value, judged to enter the subsequent step that switches for needs, i.e. step S33.On the contrary, do not satisfy the situation of the 3rd switching condition for the first wireless network signal strength, then enter step S32, further carry out the judgement of network connectivty.
Similarly, the signal strength signal intensity of above-mentioned the first wireless network can be before execution in step S31B in the second time period, and the average signal strength of the signal strength signal intensity of the first wireless network is located in the terminal present position.Accordingly, the 3rd switching condition is before execution in step S31B in the second time period, and the mean value of signal strength signal intensity of the first wireless network is located less than the 3rd threshold value in the terminal present position, and wherein, the 3rd threshold value is less than the first threshold among the step S31A.
At step S32, judge whether the connective index between the wireless network satisfies the 4th switching condition, if should the connectedness index not satisfy the 4th switching condition, judge that terminal continues to communicate by the first wireless network, if should the connectedness index satisfy the 4th switching condition, then execution in step S33.
The condition that enters step S32 is that satisfied the first switching condition of the first wireless network signal strength is located in the terminal present position, and do not satisfy the 3rd switching condition, namely can not affirm still according to the first wireless network signal strength whether terminal necessarily can't continue to use the first wireless network, perhaps, signal strength signal intensity according to the first wireless network is judged, draws and can advance to switch situation about also can not switch.Since wireless signal strength can not the complete reaction Radio Link quality, therefore, in this case, can judge further whether the connective index between terminal and the first wireless network satisfies the 4th switching condition, if connective index does not satisfy the 4th switching condition, judge that then terminal continues to communicate by the first wireless network, if connective index satisfies the 4th switching condition, situation about then switching as required judgement enters next step S33.
Specifically, can set the 4th switching condition and be terminal to the connective index between the first wireless network less than the 4th threshold value, namely judging according to the signal strength signal intensity of the first wireless network when being in still unascertainable situation about whether switching, also relatively poor when the connectedness that satisfies terminal to the first wireless network, judge that then terminal carries out network and switch.Otherwise, judge that then not carrying out network switches.Thereby, according to the actual conditions of network, further reduced the generation that network switches.
The connective index of terminal and the first wireless network can be packet loss information or the network delay information that comprises between interior terminal of the 3rd time period and the first wireless network, also can be the combination of packet loss and network delay information.Can adopt by sending the generation test packet connectedness of terminal to the first wireless network is tested, the packet loss and/or the network delay information that obtain by test packet represent the network connectivty index.When specific implementation, can in step S32, measure the above-mentioned connective index in the 3rd time period.
For example, the connective index of judging terminal and the first wireless network comprises packet loss information, this connectedness index is when satisfying the 4th switching condition, namely under the signal strength signal intensity according to the first wireless network is in still unascertainable situation about whether switching, when the packet loss that satisfies simultaneously terminal to the first wireless network large, so that, then judging the situation judgement that terminal is switched as required less than the 4th threshold value, the network connectivty of its expression enters next step.
At step S33, when satisfied first switching condition of signal strength signal intensity of the first wireless network is located in the terminal present position, judgement before carrying out this step S33 in the very first time section switching times of terminal between the first wireless network and second wireless network whether satisfy the second switching condition, if switching times does not satisfy the second switching condition, judge that then terminal continues to communicate by the first wireless network, if switching times satisfies the second switching condition, judge that then terminal switches to second wireless network from the first wireless network.
This step and step S23 are similar, referring to the introduction of abovementioned steps S23, no longer describe in detail here.
In the above-described embodiments, the first wireless network can be WLAN (wireless local area network), and second wireless network can be cdma network, and wherein, second wireless network can comprise CDMA 1X network or CDMA 1X EVDO network.
