Calculate to search next time and net interval time, search, with reference to history under current network pattern, the probability that net is failed, if history
Searching the failed probability of net high, then represent this area's network the most weak, be not added with adjusting searches net time interval according to acquiescence and searches net, general
Can bring huge kwh loss, suitably adjustment prolongation is searched and is netted interval time, it is possible to reduce search net kwh loss.
The intelligence of implementation above searches net device, when searching net with reference near history position search net successful instance, according to going through
History is searched the successful probability adjustment of net and is searched net interval, is prevented effectively from and blindly searches the problem that the kwh loss of guipure is big.
Embodiment six
Sixth embodiment of the invention proposes a kind of intelligence and searches net device, including position acquisition unit 10, searches the acquisition of train table
Unit 20, search net unit 30 and search net interval decision package 40, the most as shown in Figure 8 and Figure 9, described in search net unit 30 and comprise
Add up subelement 31 and search net decision-making subelement 32;Described search net interval decision package 40 comprise probability calculation subelement 41 and
Every decision-making subelement 42.
Statistics subelement 31, searches net number of success for search that train table adds up each network schemer according to history multimode;
Concrete, when there is multiple network schemer successfully searching net, history being searched net number of success and arranges from high to low,
I.e. preferentially can search the many network schemers of net number of success according to history to carry out searching net, have an opportunity to make the success rate searching net carry further
High.
Search net decision-making subelement 32, if searching net number of success all zero, the most not for each network schemer described
Net order is searched in adjustment;Otherwise arrange from high to low and new search net order according to searching net number of success.
Probability calculation subelement 41, searches net mistake for searching history under train table calculating current network pattern according to history multimode
The probability lost;Under current network pattern, history searches the probability that net is failed, if i.e. historical position A is under current network pattern, searches
Net 10 times, success 2 times, then search the failed probability of net 80%, failed chance is bigger, it is necessary to acquiescence is searched net time interval
Extend, it is to avoid intensive guipure of searching carrys out power wastage.
Interval decision-making subelement 42, if for described probability more than pre-set threshold value, then runs special algorithm and calculates down
Secondary search the net time and perform, otherwise performing acquiescence and search net interval time.
Concrete, special algorithm is: setting history probability of failure is P, and current number of retries is n, and next time triggers and again searches net
Time interval be T, acquiescence search net interval time be T0, then have:
The intelligence of implementation above searches net device, makes mobile terminal when suspension, searches net result according to history and select to search net
Pattern, and according to searching net result and history searches the successful probability of net, further decision is again searched the time of net, is not only increased
Once search the successful probability of net or improve and search net efficiency, in the place that the network coverage is poor, more by Reasonable adjustment again
Search the net time, reduce because not stopping to search the unnecessary kwh loss of guipure.
Embodiment seven
Seventh embodiment of the invention proposes a kind of mobile terminal 100, as shown in Figure 10, including position acquisition unit 10, searches
Train table acquiring unit 20, search net unit 30 and search net interval decision package 40.
Position acquisition unit 10, for when receiving terminal mobile communication network suspension signal, obtains current geographic position
Put;
Search train table acquiring unit 20, be used for comparing current geographic position and historical geography location information data storehouse, if
Described historical geography location information data storehouse exists the Euclidean space distance difference with current geographic position less than setting threshold values
Historical geography position, then the history multimode exporting this historical geography position corresponding searches train table;
Search net unit 30, carrying out searching net for searching train table according to described history multimode, netting successfully if searched, then will be current
Geographical position and search net result and be saved in historical geography location information data storehouse.
Search net interval decision package 40, if for when searching net and being unsuccessful, searching the calculating of train table according to history multimode and search
Net interval time, the net of searching according to calculating carries out searching net next time interval time, and by current geographic position and search net result and add
Enter historical geography location information data storehouse.
The mobile terminal of implementation above, searches net situation according to history and determines that searching of current location nets strategy, net unsuccessfully when searching
Time, search the failed probability of net further according to history, determine that next time searches the time interval of net, search net more rationality, more intelligent, be conducive to saving
Save the electricity of mobile terminal.
