Alternatively, each sector may be covered by two or more antennas for diversity reception. Each BS 270 may be configured to support multiple frequency allocations, with each frequency allocation having a specific frequency spectrum (eg, 1.25 MHz, 5 MHz, etc.).

The intersection of partition and frequency allocation may be referred to as a CDMA channel. BS 270 may also be referred to as a Base Transceiver Subsystem (BTS) or other equivalent terminology. In such cases, the term "base station" may be used to refer generally to a single BSC 275 and at least one BS 270. A base station may also be referred to as a "cell site."

As a typical operation of a wireless communication system, the BS 270 receives reverse link signals from various mobile terminals 100 . Mobile terminal 100 typically engages in calls, messaging, and other types of communications. Each reverse link signal received by a particular base station 270 is processed within a particular BS 270 . The obtained data is forwarded to the relevant BSC275. The BSC provides call resource allocation and mobility management functions including coordination of soft handover procedures between BS270. BSC 275 also routes received data to MSC 280 , which provides additional routing services for interfacing with PSTN 290 .

Based on the above mobile terminal hardware structure and communication system, various embodiments of the method of the present invention are proposed.

Embodiment one

Fig. 3 is a flow chart of a method for quickly adjusting screen brightness according to an embodiment of the present invention. The following describes a method for quickly adjusting screen brightness according to an embodiment of the present invention in conjunction with Fig. 3 , and the method is applied to A mobile terminal without a side frame, the mobile terminal is preset with a side edge area and a gesture to adjust the brightness of the screen, as shown in Figure 3, the method includes the following steps:

S100. When the mobile terminal enters the anti-mistouch mode, detect a gesture occurring in the side edge area;

S200. Determine whether the detected gesture is a gesture for adjusting screen brightness, and if so, adjust the screen brightness of the mobile terminal according to the gesture occurring in the side edge area.

Among them, the conditions for entering the above-mentioned anti-mistouch mode are:

When it is detected that there is skin contact on one edge area of the mobile terminal, it is determined that the mobile terminal enters the anti-mistouch mode.

With regard to the detection of the gesture occurring in the side edge area in the above step S100, specifically, the detection of the gesture occurring in the other side edge area of the mobile terminal.

Wherein, the above-mentioned preset side edge area refers to the edge portion on the screen of the mobile terminal that is located on the side without a side frame. The size and position of the side edge area can be determined by preset coordinates. The size and position of the side edge area and The position can be uniquely fixed, or can be modified by the user through the parameter modification interface provided by the developer.

FIG. 6 is a schematic diagram of a side edge area according to an embodiment of the present invention. As shown in FIG. 6 , the present invention divides all touch areas on the screen of a mobile terminal into a common area A and a special area C. Among them, the ordinary partition is the touch area in the prior art, which is used to normally receive the touch operation of the user and execute the corresponding instruction; Side edge area to prevent misuse and adjust screen brightness.

According to an example of this embodiment, the manner of determining whether the touch point of the touch operation is within the edge area is as follows.

Since touch operations are usually operations such as clicking and sliding, and each touch operation is composed of one or more touch points, the terminal can determine whether the touch operation is Occurs in ordinary partitions or edge areas (that is, special partitions). In terms of specific implementation, the coordinates of the touch point of the touch operation are acquired through the driver layer of the terminal, and it is judged which partition the coordinate of the touch point falls into. When the coordinates of the touch point fall into the special partition, it is determined that the touch operation occurred in the special partition, and the touch operation is reported through the input device corresponding to the special partition; when the coordinates of the touch point fall into the common partition, it is determined The touch operation occurs in the common partition, and special effects are generated according to the touch operation, and routine processing is performed.

After the Framework layer receives the reporting event (the reporting event includes the parameters of the input device and the touch point, etc.), it first identifies which area it is based on the name of the input device, such as the driver layer (kernel) identification in the previous step If the touch is in a special partition, the input device reported by the driver layer to the framework layer is input1 instead of input0, that is, the framework layer does not need to determine which partition the current touch point is in, nor does it need to judge the size of the partition and position, these judgment operations are completed on the driver layer, and in addition to reporting the specific input device, the driver layer will also report various parameters of the touch point to the framework layer, such as pressing time, position coordinates, pressure, etc. Wait.

When the touch point of the touch operation falls into the common partition, the driver layer of the mobile terminal reports the touch point through the input device corresponding to the common partition.

After the Framework layer receives the reporting event (the reporting event includes the parameters of the input device and the touch point, etc.), it first identifies which area it is based on the name of the input device, such as the driver layer (kernel) identification in the previous step If it is touched in a common partition, the input device reported by the driver layer to the framework layer is input0 instead of input1. That is, the framework layer does not need to determine which partition the current touch point is in, nor does it need to judge the size of the partition and position, these judgment operations are completed on the driver layer, and in addition to reporting the specific input device, the driver layer will also report various parameters of the touch point to the framework layer, such as pressing time, position coordinates, pressure, etc. Wait.

The conventional processing of the touch operation is to process the touch operation according to the conventional flow in the prior art. For example, after receiving the touch point reported by the input device corresponding to the common partition, the framework layer of the terminal continues to report the touch point according to the normal process, so as to execute the corresponding operation instruction.

Therefore, in this embodiment, special effects are generated according to the touch operations reported by special partitions instead of performing conventional processing, so as to prevent misoperations as well.

The size of the above-mentioned preset edge area can be a fixed value. When the edge area includes multiple blocks, a corresponding input device can be set for each edge area to adjust the position and size of the edge area. When the edge area When the size of is a variable, it can be realized through the parameter modification interface reserved by the developer. As shown in Figure 6, the developer uses the interface Set_zone(id,X ₀ ,Y ₀ ,X ₁ , Y ₁ ) is for users to set. In Figure 6, when id is 1, it represents the left edge area, and the corresponding preset coordinates are (X ₀ , Y ₀ , X ₁ , Y ₁ ), when id is 2, it represents the right edge area, and the corresponding preset coordinates are (X 0 , Y 0 , X 1 , Y 1 ). The set coordinates are (X ₀ ', Y ₀ ', X ₁ ', Y ₁ '), which can be preset in the above interface functions.

In Figure 7, the ordinary area is referred to as area A, and the edge area is referred to as area C. The reporting process of touch events is as follows:

The driver layer receives touch events through physical hardware such as a touch screen, and judges whether the touch operation occurs in area A or area C, and reports the event through the device file node of area A or area C. The Native layer reads events from the device files in Area A and Area C, and processes the events in Areas A and C, such as coordinate calculation, distinguishes the events in Areas A and C through the device ID, and finally dispatches the events in Area A and Zone C incidents. Among them, the events in area A follow the native process, and the events in area A are processed in the usual way, that is, through the multi-channel mechanism; the events in area C are dispatched from the dedicated channel of area C registered in the Native layer in advance, and the Native port Input, system port output to the C area event to end the system service, monitor the C area event through the listener (listener), and then report to each application through the C area event receiving external interface. The invention utilizes the driver layer code of the mobile terminal to realize the free customization of the anti-mistouch area, that is, the edge area. Therefore, the realization of the technical solution of the invention is in the driver layer rather than in the firmware, which makes the software design of the device get rid of the touch screen The shackles of IC suppliers enable more flexibility and lower cost.

The preferred number of special partitions is two, which are respectively located on the two side edges of the touch area, and the remaining areas of the touch area are common partitions. Alternatively, the common partition includes the touchable area A and the virtual button area at the bottom, which are used to detect menu keys, home keys, return keys, etc., and two special partitions are respectively set on the edge of the touch area and on both sides of the A area. In addition, special partitions can also be set in any other areas that are likely to cause misoperation according to needs, or only one special partition or multiple edge areas can be set.

After the partition setting is completed, two input devices (input), such as input device 0 (input0) and input device 1 (input1), can be registered through the input_register_device() command when the touch screen driver is initialized. And assign an input device to each partition through the input_allocate_device() command, for example, the common partition corresponds to input device 0, and the edge area corresponds to input device 1.

The specific method of implementing this partition can be by using an object-oriented approach to define the categories and implementation methods of common partitions and edge areas. After judging that it is an edge area, use the EventHub function to convert the coordinates of touch points with different resolutions into LCD coordinates. Coordinates, define a single channel function (such as serverchannel and clientchannel, etc.), the function of this function is, after receiving the reported event, pass the event to the event manager (TouchEventManager) through the channel, and through the monitoring of the listener, the The event can be delivered to multiple corresponding application modules simultaneously or one by one through multiple channels, or can be delivered to only one of the application modules, such as camera, gallery, etc., and different application modules will generate corresponding operations. Of course, the specific implementation of the above steps may also be implemented by steps in other manners, which are not limited in this embodiment of the present invention.

When receiving a touch operation reported from an input device corresponding to a common partition, the system will identify which one it is based on the name of the input device after receiving the reported event (the reported event includes the input device and various parameters of the touch point, etc.). area.

The above-mentioned gestures for adjusting screen brightness include gestures for increasing screen brightness and gestures for decreasing screen brightness. Gestures for adjusting screen brightness include but are not limited to the following methods: slide the mobile terminal up/down on the screen of the mobile terminal to Increase/decrease the brightness of the mobile terminal screen; slide the mobile terminal up/down on the side edge area of the mobile terminal to increase/decrease the brightness of the mobile terminal screen; press and hold the increase/decrease button on the mobile terminal, to increase/decrease the brightness of the mobile terminal screen.

In this embodiment, in the process of judging that the current operation is brightness adjustment, the condition of preventing false touches is added. One is that when the user holds the mobile terminal or is using other applications, it is easy to generate a preset adjustment screen. The same gesture as the brightness gesture, entering the anti-mis-touch mode can avoid misuse; the second is to enable the mobile terminal to determine that the user's current operation is adjusting the brightness, not other volume adjustments, etc., so that the terminal obtains the screen brightness adjustment. The information is more accurate, so that the adjustment of the mobile terminal by the user is more satisfactory.
