[embodiment]
Core concept of the present invention is: on the one hand, the position of UIM deck can be arranged at portable terminal side (i.e. the position that can not covered by battery), on structural design, can stay next UIM deck position at side, like this, the battery of in plug UIM card, just needn't choosing earlier; On the other hand, increase the UIM card Plug Action measuring ability of UIM deck and the Interrupt Process function of baseband processor, like this, the UIM deck can be notified baseband processor in plug UIM card, and then baseband processor is carried out corresponding operating.
As shown in Figure 1, the portable terminal of realization UIM card hot plug comprises in the present embodiment: baseband processor, UIM deck, memory, protective circuit, other control circuits; And baseband processor comprises the GPIO interrupt pin.Wherein,
The UIM deck comprises power pins, and this power pins is connected with the GPIO interrupt pin of baseband processor, is used to survey the insertion/pull action of UIM card and sends interrupt signal to baseband processor when detecting;
Baseband processor is used for when receiving the interrupt signal of UIM deck, judges the state of current UIM card and carries out respective handling in view of the above;
Protective circuit is used for that the closed-loop adjustment by control circuit and comparison circuit limits excessive pulse current when the power pins generation voltage jump of UIM deck.
See also Fig. 2, realize in the present embodiment that the method for UIM card hot plug may further comprise the steps:
201, the UIM deck is located at the position that the edge of portable terminal or other can not covered by battery.
202, the insertion or the pull action of UIM deck real-time detection UIM card, and when detecting this action, send interrupt signal to baseband processor.
203, after described baseband processor receives the interrupt signal that the UIM deck sends, judge the state of current UIM card and enter corresponding handling process in view of the above.
Because when the UIM card is extracted, the power pins of UIM deck is unsettled, this moment, this power pins was a high level, and when the UIM card inserts, the power pins conducting of UIM deck, this moment, this power pins was a high level, so in said method, the power pins of UIM deck can be monitored the level of self in real time, according to level whether saltus step takes place and judges whether current UIM takes place to insert or pull action; And baseband processor is after receiving interrupt signal, also can judge that just the state of current UIM card is that the insertion state is still extracted state according to the level of the power pins of current UIM deck.
See also Fig. 3, this figure is depicted as and uses the process that portable terminal of the present invention realizes that the UIM card is extracted, and comprising:
301, from the UIM deck, extract the UIM card, trigger interrupt signal.
302, after baseband processor receives interrupt signal, the power pins that identifies the UIM card is a high level, then judge current UIM card for extracting state, the driving of startup UIM card is carried out the UIM card and is extracted flow processing, promptly unloads the driving of UIM card and discharges its shared resource.
303, upper layer application is carried out the UIM card and is extracted flow processing; This step further comprises: if current mobile terminal is not moved the application program of UIM card, then need make the UIM card application enter resting state, can not be activated by the user, and discharge the shared system resource of UIM card application; If current mobile terminal is being moved the application program of UIM card, then need close the thread that is associated with the UIM card that is moving, and extract to user prompt client UIM card, the processing operation when subsequent operation will not move the application program of UIM card according to above-mentioned current mobile terminal is carried out.
See also Fig. 4, this figure is depicted as and uses the process that portable terminal of the present invention realizes that the UIM card inserts, and comprising:
401, in the UIM deck, insert the UIM card, trigger interrupt signal;
402, after baseband processor receives interrupt signal, the power pins that identifies the UIM card is a low level, judge that then current UIM card is the insertion state, start UIM card driving carrying out UIM card and insert flow processing, promptly the UIM card drives the initialization hardware relevant with the UIM card and also applies for the required system resource of UIM card operate as normal.
403, upper layer application is carried out UIM card insertion flow processing; Be initialization and the needed system resource of UIM card related application, and activate the application program of UIM card.
Above embodiment is only unrestricted in order to technical scheme of the present invention to be described, only with reference to preferred embodiment the present invention is had been described in detail.Those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention, and do not break away from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of the claim scope of the present invention.
