nRepresent these regional location data compared to importance of searching other All Ranges position data among the recommendation form Table 1 and use priority.When every regional location data The corresponding area scope overlaps to some extent, then portable radio device 10 determines the regional location data that will adopt according to the height of weighted value.Or even, there is the weighted value of arbitrary regional location data to be lower than certain preset standard if search in the recommendation form, then these data will be left in the basket.Among the different embodiment, weighted value W may determine by different parameters.For example, among the search recommendation form Table 1 shown in Fig. 2 a, the weighted value of every regional location data is determined with the sequencing of the settling time of these regional location data.In this example, more early represent these regional location data old more settling time, and therefore corresponding weighted value is low more.In searching recommendation form Table 1, every regional location data all have a corresponding field to note down the time that these regional location data are established (or being updated); For example, the regional location data A shown in Fig. 2 a
1Settling time be on April 2nd, 2008, and regional location data A
pSettling time be on March 11st, 2008 because the weighted value of the data that more early are established is low more, so present embodiment gets these two pairing weighted values of data and is respectively W
1=0.5, W
p=0.3.
Among other embodiment, the weighted value of every regional location data can be set according to other parameter.For instance, the weighted value of regional location data can be set according to the number of times of setting up corresponding in the regional location data of searching recommendation form.Setting up the number of times meaning is communication network repeats to receive identical regional location data from separate sources number of times.For example, have two different portable radio devices to transmit identical position data to communication network, then communication network institute according to this number of times of setting up of these regional location data of foundation be 2.The correspondence of a different regional location data is set up the number of number of times, can be used as the parameter of the weighted value of regional location data.Generally speaking, a certain regional location data to set up number of times few more, it is few more to represent portable radio device to enter this regional number of times, so the pairing weighted value of these regional location data is low more.As previously mentioned, search recommendation form of the present invention (no matter being) via the communication network end or via the portable radio device end for bringing in constant renewal in, therefore, the weighted value of every data correspondence also may be changed because of the renewal of other data.In addition, other parameter that default or user set up on their own also can be applicable to set weighted value, and the present invention is not limited to the setting means of above-mentioned two embodiment.
Fig. 3 a is the method flow diagram of the setting communication network search time of one embodiment of the invention.The method is applicable to portable radio device of the present invention, and this portable radio device comprises wireless communication module and locating module.Wireless communication module can be for being connected in communication network, and locating module is used to calculate the position data of portable radio device.As Fig. 3 a, the method for the communication network search time of present embodiment comprises, at first carry out step 1005, checks the whether successful connection of the wireless communication module of portable radio device and communication network.If with the communication network successful connection, carry out step 1010, if with the communication network connection failure, then carry out step 1020.At first narrate method flow with the communication network successful connection.Receive and store the search recommendation form from communication network in the step 1010, and upload the position data of previous storage.This searches and comprises many regional location data and corresponding a plurality of suggestion search times in the recommendation form.In step 1012, further from the search recommendation form of downloaded renewal, this step can be regularly or irregularly carries out, and decides on different designs.In addition, portable radio device is searched communication network with the proper communication Web search time in step 1014.It should be noted that the actions that step 1010,1012 and 1014 can be carried out for portable radio device in method of the present invention, but do not have absolute sequencing, visual different embodiment or different application and be adjusted.
If portable radio device among the following key diagram 3a is the steps flow chart that is carried out with the communication network connection failure.At first carry out step 1020, calculate position data instantly and store it, and enable the search recommendation form.Then, carry out step 1021, whether judgement or the position data that calculates more instantly are arranged in is searched any regional location data of recommendation form.If step 1021 is for being, then then carry out step 1023, otherwise get back to step 1005, reexamine and whether successful connection of communication network.Find the regional location data of correspondence position data in the step 1021, then carry out step 1023, judge further whether pairing weighted value is higher than preset standard in these regional location data.If result of determination is for being higher than preset standard, then carry out step 1025, adopt the pairing suggestion search time of these regional location data to search communication network, if weighted value does not reach preset standard, represent that these regional location data have not conformed to the employing standard, therefore carry out step 1027.Step 1027 is ignored these regional location data, and gets back to step 1005.
Fig. 3 b is the flow chart of another embodiment of setting communication network search time method.Specifically, the flow chart under the situation of the connection failure of portable radio device and communication network, being carried out shown in this figure.At first, be similar to previous embodiment, step 1005 is checked the whether successful connection of the wireless communication module of portable radio device and communication network, if not, then carry out step 1020.In step 1020, calculate, store the position data of portable radio device.Then, carry out step 1021, whether judgement or the position data that calculates more instantly are arranged in is searched any regional location data of recommendation form.If step 1021 for being, then carry out step 1022, otherwise carry out step 1020.Step 1022 judges whether position data is positioned at the regional extent of two or more regional location data, if, then carry out step 1024, the weighted value of a plurality of regional location data that the comparison position data are positioned at, then in step 1026, the regional location data that have the higher weights value in the comparison step 1024 are used, and the pairing suggestion search time of regional location data is searched communication network in view of the above.If step 1022 is judged as not, represent that then position data only falls within the single area position data; Then carry out step 1023, judge whether pairing weighted value is higher than preset standard in these regional location data, then carries out other step according to the flow process shown in Fig. 3 a afterwards.
What deserves to be mentioned is that the weighted value of indication can have different set among Fig. 3 a and Fig. 3 b.Among one embodiment, the weighted value of regional location data was set according to the settling time of regional location data, settling time regional location data more early, representative data is old more, so weighted value is low more.Among another embodiment, the weighted value of regional location data is set according to the setting up the number of times number of regional location data; Set up number of times meaning and be the number of times of the same area position data that communication network receives.Generally speaking, a certain regional location data to set up number of times few more, it is few more to represent portable radio device to enter this regional number of times, so the pairing weighted value of these regional location data is low more.Other embodiment also may have other setting means to weighted value, is all the usual application person of personage who knows this area, does not add at this and gives unnecessary details.
In sum, when portable radio device of the present invention and communication network connection failure, the communication network search time can be adjusted into the suggestion search time, the time interval length of this suggestion search time is greater than the time interval length of proper communication Web search time, the search time when wherein the proper communication Web search time refers to portable radio device and communication network successful connection.Therefore, portable radio device of the present invention can be reached the purpose of saving electric power and mitigation system load by adjusting the time of searching communication network with the method for setting the communication network search time.
