The accompanying drawing used required in detailed description of the invention or description of the prior art will be briefly described by face,
It should be evident that the accompanying drawing in describing below is some embodiments of the present invention, general for this area
From the point of view of logical technical staff, on the premise of not paying creative work, it is also possible to obtain according to these accompanying drawings
Obtain other accompanying drawing.
Fig. 1 is the roaming method for searching network flow chart of a kind of mobile phone in the embodiment of the present invention;
Fig. 2 is that in the embodiment of the present invention, net principle of device block diagram is searched in the roaming of a kind of mobile phone.
Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme is clearly and completely described, it is clear that
Described embodiment is a part of embodiment of the present invention rather than whole embodiments.Based on this
Embodiment in bright, those of ordinary skill in the art are obtained under not making creative work premise
Every other embodiment, broadly fall into the scope of protection of the invention.
As long as additionally, technical characteristic involved in invention described below difference embodiment that
The conflict of not constituting between this just can be combined with each other.
In order to realize in the case of cross-border roaming, improve mobile phone searching network and set up the effect that network connects
Rate, present embodiment discloses the roaming method for searching network of a kind of mobile phone, refer to Fig. 1, for the method flow process
Figure, the roaming method for searching network of this mobile phone comprises the steps:
Step S100, the network signal of capture base station.In a particular embodiment, when mobile phone is in roaming place
When starting shooting or roam to roaming place, can be by the base station net of the communication module capture roaming place of mobile phone
Network signal (also known as cell signal).In the present embodiment, the system that can start mobile phone wireless communication is wide
Broadcast, to monitor this system broadcasts, from the system broadcast message listened to, capture the network signal of base station.
Step S200, obtains the country identification code of roaming place according to network signal.Generally, network signal
Carry the country identification code of this area/country, after capturing the base station network signal of roaming place, can
To resolve the country identification code obtaining roaming place, such as China's Mainland is 86, Hong-Kong is 85 etc..
After acquiring the country identification code of roaming place, the roaming place that mobile phone is presently in, example can be known
Such as China's Mainland or Hong Kong etc., it should be noted that the countries and regions in above-described embodiment are merely illustrative,

Step S300, extracts the network list mapped with this country identification code according to country identification code.?
In specific embodiment, country variant identification code and network list can be stored the most respectively
Mapping relations, after step S200 acquires the country identification code of roaming place, can be according to this mark
Code extracts the network list mapped with this country identification code from system database.In preferred embodiment
In, network list includes operator identifier list (PLMN list) and with each operator (in such as
State moves) corresponding network formats list (such as CDMA, LT, GSM etc.).
Step S400, searches for available network from network list and connects to set up network.At the net extracted
In network list, available network based on preset rules search different frequent points, thus realize mobile phone and base station
Between network connect.In a preferred embodiment, when network list include operator identifier list and
During corresponding with each operator network formats list, it may be preferred to based on priority rule from operator identifier
List selects carrier network, then, according to carrier network at the net corresponding with carrier network
Network standard list is searched for available network connect to set up network.Such as, the external mobile communication in certain fortune
The network of battalion business has different priority level data and mates from the operator identifier in continent, therefore, when
After this cellphone subscriber enters China's Mainland, can first select from its mobile phone database based on priority rule
Preferential common carrier network (such as China Mobile), then from the network that this carrier network is corresponding
Standard list (such as CDMA, LT, GSM etc.) search available network, to realize what network connected
Set up.
In order to improve the specific aim of roaming place network data, in a preferred embodiment, step is being performed
Before S100, it is also possible to farther include: receive country's identification code and the net corresponding with country identification code
Network list, specifically, can preset the most in systems, it is also possible to come according to the selection of user
Obtain country identification code and the network list corresponding with country identification code, then set up and store country's mark
Know code and the mapping relations of network list.Thus, also allow for user and roaming place can be pre-selected, arrive
After reaching roaming place, it is possible to extract corresponding network list more quickly, it is achieved network connect search and
Set up.
The present embodiment also discloses the roaming of a kind of mobile phone and searches net device, including: signal capture unit 100,
