Embodiment
Below, 1～2 describe method and the device that realization of the present invention multifrequency terminal frequency range is switched in detail with reference to the accompanying drawings.
As shown in Figure 1, the method that the realization multifrequency terminal frequency range of the embodiment of the invention is switched comprises the following steps:
Step 101: the user selects the network band operation;
Wherein, in step 101, the user can select the network frequency range by the menu interface mode, comprises 800M network, inferior 800M network etc.
Step 102: judge whether the network frequency range that the user selects is the network frequency range of current terminal locking, if not, then control terminal off-grid, and execution in step 103; Otherwise, finish.
Step 103: terminal is carried out web search according to the setting in roaming list in advance.
Wherein, in step 103, be to search for according to the record inside the roaming list of terminal.Such as the system log (SYSLOG) that a 800M and one 800M are arranged inside the roaming list, suppose that 800M network wherein is preferred network (this can be provided with in the roaming list the inside), the then frequency of first search 800M, the frequency of the inferior 800M of search and then.In addition, this roaming list can be that the user works out or (Dual Mode Subscriber Station DMSS) creates and to form by the dual-mode terminal travelling carriage, comprise Preferred Roaming List (Preferred Roaming List, PRL) or the terminal frequency tabulation of searching for recently.Must comprise the recorded content of the frequency range that terminal supports in the present invention in the roaming list, terminal can be switched between the different frequency range that is write down.
Step 104: when terminal searches network again, judge whether the affiliated frequency range of the frequency that captures is the network that the user selects, if, then locking this frequency range, the frequency range switching is finished; Otherwise, according to being provided with in the roaming list next frequency range record is searched for, till the network frequency range that frequency range under the frequency that captures is selected for the user.
As shown in Figure 2, the realization multifrequency terminal frequency range device for switching of the embodiment of the invention comprises user's operational module, control module, web search module, system determination module.
Wherein, user's operational module is used to the user that the network Frequency Band Selection is provided.When specific implementation, can be various detectable user's operational modules such as menu selection operation, shortcut operation, order input operation, acoustic control operation, inductive operation.
