Embodiment one
The embodiment of the present invention provides a kind of network search method, is applied to terminal, and the terminal can be mobile phone, plate electricity
Brain and other equipment that can be connected and communicated with base station foundation, it is not limited in the embodiment of the present invention.As shown in figure 3,
The described method includes:
Step 301, when terminal is in network loss state, determine whether the signal strength of the terminal current location small
In or equal to preset strength threshold value.
In the prior art, can result in the case where terminal network is lost has very much, and it is larger to common are network load, or
Terminal position signal is weaker.If the terminal network as caused by network load is larger is lost, illustrate terminal current location
Signal strength it is good, only because network load is larger, can not continue to establish connection with terminal, need at this time terminal as early as possible into
Row web search so as to re-search for network signal, and is resident, therefore the search cycle is the smaller the better；If by
The terminal network caused by terminal position signal is weaker is lost, and illustrates that terminal may be currently located at the area that signal can not cover
Domain can not also re-search for network signal and be resident even if terminal ceaselessly carries out web search at this time, therefore search for
Period can be appropriately extended.It can be seen from the above, in the case where difference, requirement of the terminal to the search cycle be it is different, therefore
When terminal is in network loss state, need to determine the reason of causing network loss first, it is exemplary, it can determine first eventually
Whether the signal strength of end current location is less than or equal to preset strength threshold value.
When initialization, preset strength threshold value can be set in the terminal, and in practical applications can be according to specific feelings
Condition is adjusted, and it is not limited in the embodiment of the present invention.Exemplary, the preset strength threshold value can be -80dBm (decibel
Milliwatt), if the signal strength of the terminal current location is greater than or equal to -80dBm, illustrate the signal strength of terminal current location
It is relatively strong, it needs to carry out web search as early as possible, in order to which terminal re-starts communication；If the signal strength of the terminal current location
Less than -80dBm, illustrates that the signal strength of terminal current location is weaker, need to reasonably adjust the search cycle, so as not to it is excessively frequent
Search for high power consumption caused by network.
Step 302, when the signal strength of the terminal current location be less than or equal to the preset strength threshold value when, according to
Accumulative searching times in current network lost condition obtain the search cycle of this search, and the described search period searches with described
Rope number increases and is incremented by, and is less than or equal to predetermined period threshold value.
It is exemplary, the counter for recording searching times can be set in the terminal, when terminal entering network is lost
When mistake state, the counter is activated and is started counting, and the every progress primary network search of terminal, counter adds 1, when terminal again
After searching network signal and being resident, the counter O reset, so what is recorded in the counter is network loss state
The accumulative searching times of middle terminal.If the signal of terminal current location is weaker, terminal is accumulative in current network lost condition
Searching times are bigger, illustrate that the signal of current location is more bad, even if terminal frequent progress web search can not also search net
Network signal, therefore search cycle when each search can be appropriately extended, avoid terminal from frequently flogging a dead horse.Optionally, described
Search cycle can be incremented by as described search number increases, i.e. accumulative search of the terminal in current network lost condition time
Number is bigger, then the search cycle of this search is longer.If search cycle unconfined increase, it is possible that terminal into
The case where entering the good region of signal, but web search cannot be carried out in time, therefore when initialization, it can preset in the terminal week
Phase threshold value, the maximum value for the limit search period.If being determined according to the accumulative searching times in current network lost condition
This search search cycle be greater than predetermined period threshold value, then in this web search, can using predetermined period threshold value as
Search cycle scans for.
Optionally, in the search cycle for obtaining this search according to the accumulative searching times in current network lost condition
When, it can determine whether the accumulative searching times in the current network lost condition are less than or equal to preset search threshold first
Value, if the accumulative searching times in the current network lost condition are less than or equal to the preset search threshold value, according to formula
(1) search cycle of this search is obtained；The formula (1) are as follows: T=Tlint+N*TStep；Wherein, the T searches for this
The search cycle of rope, the TlintFor the default search periods of terminal, the N is the accumulative search in current network lost condition
Number, the TStepFor preset search delay.
Exemplary, preset search threshold value, T can be arranged in when initialization in the terminal firstlintAnd TStep, that is, terminal is set
Maximum search number under each network loss state, the search cycle of terminal default and the increased fixation of each search cycle
Duration.The preset search threshold value is used for the maximum value of limit search number, and the search cycle of the terminal default is that terminal exists
The search cycle of web search is carried out under current network lost condition for the first time, it can be with search cycle phase in the prior art
Together, it can also be different, it is not limited in the embodiment of the present invention；The increased fixed duration of each search cycle indicates adjacent
The time difference of the search cycle of web search twice.When terminal carries out this web search, record search can be read first
The numerical value of the counter of number obtains the accumulative searching times in current network lost condition, then determines the accumulative search time
Whether number is less than or equal to preset search threshold value, if accumulative searching times are less than or equal to preset search threshold value, illustrates currently tired
Meter searching times are smaller, the shorter search cycle can be selected to carry out web search, therefore can use formula T=Tlint+N*
TStepThe search cycle of this search is calculated, the N is the counting in counter.
Optionally, if the accumulative searching times in the current network lost condition are greater than the preset search threshold value,
The search cycle of this search is the predetermined period threshold value, and the predetermined period threshold value and the preset search threshold value are full
Sufficient formula TY=Tlint+TMAX*TStep；Wherein, the TYFor the predetermined period threshold value, the TlintFor the default search of terminal
Period, the TMAXFor the preset search threshold value, the TStepFor preset search delay.
It is exemplary, when initialization, predetermined period threshold value can be directly set in the terminal, preset search threshold also can be set
Then value obtains predetermined period threshold value, the predetermined period threshold value and the preset search threshold value according to the preset search threshold value
Meet formula TY=Tlint+TMAX*YStep。
Step 303 searches for network according to the search cycle of this search.
It is exemplary, timer can be set in the terminal, and after each web search is completed, timer starts timing, eventually
End can determine the search cycle searched for next time according to the accumulative searching times in current network lost condition, then read meter
When device record time, determine whether the time is greater than or equal to the search cycle searched for next time or predetermined period threshold
Value carries out network next time if the time is greater than or equal to the search cycle searched for or predetermined period threshold value next time

Embodiment two
The embodiment of the present invention provides a kind of network search method, is applied to terminal, and the terminal can be mobile phone, plate electricity
Brain and other equipment that can be connected and communicated with base station foundation, it is not limited in the embodiment of the present invention.It can when initialization
Preset strength threshold value, preset search threshold value, default search periods and preset search delay to be arranged in the terminal, and according to pre-
If searching threshold, default search periods and preset search delay acquisition predetermined period threshold value.As shown in figure 4, the method packet
It includes:
Step 401, when terminal entering network lost condition, determine whether the load of terminal current network is less than or equal to
Default load threshold；When the load of terminal current network is less than or equal to default load threshold, step 402 is executed；Work as terminal
When the load of current network is greater than default load threshold, step 411 is executed.
Exemplary, common has network load larger or terminal position letter the reason of causing terminal network to be lost
It is number weaker.Assuming that causing terminal network to be lost by network load is excessive, if the search cycle is excessive, being likely to result in terminal can not
In time the case where access network, user experience is influenced；Assuming that causing terminal network to be lost by signal is weaker, if search cycle mistake
It is small, it will cause the case where terminal frequently searches for network and can not search network signal always, and then cause power consumption of terminal excessive.
Therefore requirement of the network loss to the search cycle caused by different reasons is different, when terminal network is lost, needs to determine first
The reason of causing terminal network to be lost.Specifically, may first determine whether is that network load is excessive, can also determine first is
It is no be terminal current location signal it is weaker, it is not limited in the embodiment of the present invention.
Exemplary, the default load threshold that when initialization is arranged can be 10000, indicate the end that current network at most accesses
Holding quantity is 10000, if the terminal quantity of current network access is greater than 10000, illustrates that current network load is larger；If current net
The terminal quantity of network access is less than or equal to 10000, illustrates that current network load is smaller.
Step 402 determines whether the signal strength of terminal current location is less than or equal to preset strength threshold value；When terminal is worked as
When the signal strength of front position is less than or equal to preset strength threshold value, step 403 is executed；When the signal strength of terminal current location
When greater than preset strength threshold value, step 411 is executed.
It is exemplary, when the load of terminal current network is less than or equal to default load threshold, illustrate terminal current network
It loads smaller, it is impossible to cause terminal network to lose, therefore the reason of terminal network loss may be the letter of terminal current location
It is number weaker, therefore can determine again whether the signal strength of terminal current location is less than or equal to preset strength threshold value.Assuming that
The preset strength threshold value be -80dBm (decibel milliwatt), if the signal strength of the terminal current location be greater than or equal to -
80dBm illustrates that the signal strength of terminal current location is stronger, needs to carry out web search as early as possible, in order to which terminal re-starts
Communication；If the signal strength of the terminal current location is less than -80dBm, illustrate that the signal strength of terminal current location is weaker, needs
The search cycle is reasonably adjusted, in order to avoid excessively frequently search for high power consumption caused by network.
Accumulative searching times in step 403, acquisition current network lost condition, execute step 404.
It is exemplary, the counter for recording searching times can be set in the terminal, when terminal entering network is lost
When mistake state, the counter is activated and is started counting, and the every progress primary network search of terminal, counter adds 1, when terminal again
After searching network signal and being resident, the counter O reset, therefore so what is recorded in the counter is network loss
The accumulative searching times of terminal in state, can by read counter records data acquisition current network lost condition in
Accumulative searching times.
Step 404 determines whether the accumulative searching times are less than or equal to preset search threshold value；If accumulative searching times
Less than or equal to the preset search threshold value, step 405 is executed；If accumulative searching times are greater than the preset search threshold value, hold
Row step 406.
It is exemplary, it is assumed that the preset search threshold value is 20, can read the data of counter records, determine that the data are
It is no to be greater than or equal to 20, when the data are greater than or equal to 20, illustrate that the number of terminal progress web search is more；When described
When data are less than 20, illustrate that the number of terminal progress web search is less.
Step 405, the search cycle that this search is obtained according to the accumulative searching times in current network lost condition, hold
Row step 407.
It is exemplary, if the signal of terminal current location is weaker, the terminal accumulative search in current network lost condition time
Number is bigger, illustrates that the signal of current location is more bad, even if terminal frequent progress web search can not also search network signal,
Therefore search cycle when each search can be appropriately extended, terminal is avoided frequently to flog a dead horse.Optionally, the described search period
It can be incremented by as described search number increases, i.e. accumulative searching times of the terminal in current network lost condition are bigger,
Then the search cycle of this search is longer.
Preferably, the search cycle of this search can be obtained according to formula (1)；The formula (1) are as follows: T=
Tlint+N*TStep；Wherein, the T is the search cycle of this search, the TlintFor the default search periods of terminal, the N
For the accumulative searching times in current network lost condition, the TStepFor preset search delay.
Step 406, the search cycle for searching for predetermined period threshold value as this execute step 407.
It is exemplary, if search cycle unconfined increase, it is possible that terminal comes into the good region of signal,
But the case where web search cannot be carried out in time, therefore when initializing, can predetermined period threshold value in the terminal, searched for limiting
The maximum value in rope period.If according to the search week for this search that the accumulative searching times in current network lost condition are determined
Phase is greater than predetermined period threshold value, then in this web search, can be scanned for using predetermined period threshold value as the search cycle.
In practical application, preset search threshold value, default search periods and preset search delay can also be set first, so
Afterwards according to preset search threshold value, default search periods and preset search delay acquisition predetermined period threshold value, the predetermined period
Threshold value, preset search threshold value, default search periods and preset search delay meet formula TY=Tlint+TMAX*TStep, the TY
For the predetermined period threshold value, the TlintFor the default search periods of terminal, default search periods of terminal under normal conditions
It is smaller, the TMAXFor the preset search threshold value, the TStepFor preset search delay, such as 0.2s, indicates two neighboring and search
Time difference between the rope period, work as TMAXAfter determination, according to TMAXIt can determine that TY。
Step 407 searches for network according to the search cycle of this search, executes step 408.
It is exemplary, timer can be set in the terminal, and after each web search is completed, timer starts timing, eventually
End can determine the search cycle searched for next time according to the accumulative searching times in current network lost condition, then read meter
When device record time, determine whether the time is greater than or equal to the search cycle searched for next time or predetermined period threshold
Value carries out network next time if the time is greater than or equal to the search cycle searched for or predetermined period threshold value next time
Search, if the time is less than the search cycle searched for next time, timer continues timing, is greater than until the time of record
Or the search cycle searched for next time or predetermined period threshold value equal to terminal acquisition.
When terminal entering network lost condition carries out web search for the first time, network can be carried out with default search periods
Search, i.e., when terminal entering network lost condition, timer starts timing, writes from memory when the duration of timer record is greater than or equal to
When recognizing the search cycle, terminal carries out web search.
Step 408 determines whether terminal network search succeeds；When terminal network is searched for successfully, step 409 is executed；When
When terminal network search failure, step 401 is executed.
It is exemplary, if searching network signal in this search of terminal, the success of this web search；If terminal this search
Suo Zhongwei searches network signal, then this web search fails.
Step 409, determine terminal whether success in net；When terminal success in net, step 410 is executed；When terminal stays net
When failure, step 401 is executed.
Exemplary, terminal is after searching network signal, it is also necessary to and the network signal is resident in a network, is claimed
For in net, after being resident successfully, terminal can establish connection and be communicated with base station.
Step 410, terminal establish connection with base station again, and are communicated, this process terminates.
It is exemplary, when terminal success in net, illustrate that this is searched for successfully, terminal can re-start communication.
Step 411 searches for network according to the default search periods of terminal, this process terminates.
It is exemplary, if the load of terminal current network is greater than default load threshold, illustrate that the network loss of terminal is to work as
Caused by the load of preceding network is larger, it is therefore desirable to which terminal carries out web search in time, in order to search network as early as possible and connect
Enter, continue to communicate, network can be searched for according to the default search periods of terminal.
When the signal strength of terminal current location be greater than preset strength threshold value when, illustrate terminal network loss be not by
Caused by signal strength is weaker, it is therefore desirable to terminal carries out web search in time, in order to search network as early as possible and access,
Continue to communicate, network can be searched for according to the default search periods of terminal.
