Method for limiting call under low signal and system thereof

The present invention relates to a method for restricting a call, and more particularly to a system for limiting a call request at a low signal and a system for its application.

With the advancement of technology, mobile communication devices (such as mobile phones or mobile stations) have become an integral part of daily life, and wireless signals are used between mobile phones and base stations. For the purpose of communication, the most widely used communication service network on the market is the most popular for Global System for Mobile communication (GSM). When the mobile phone is located within the communication range of the base station, the mobile phone can obtain the appropriate level of wireless resources by sending a request for a communication link to the base station, thereby achieving the purpose of the call.

However, the communication range that a single base station can cover is quite limited. Therefore, when the mobile phone leaves the communication range of one base station and enters the communication range of another base station, the two base stations will re-allocate the mobile phone to the wireless resource. . Simply put, the original base station will first cut off the wireless resource connection with the mobile phone, and then the mobile phone will establish a new link with the new base station. However, because the mobile phone has to establish a new connection with different base stations when moving between the two base stations, it may result in poor call quality. Furthermore, if there is a shortage of radio resources left in the new base station, it may even lead to a situation of forced to terminate.

In addition, the quality of the call of the mobile phone is affected by the above factors. Since the mobile phone and the base station transmit signals by means of electromagnetic waves, the wireless connection between the two is easily subject to obstacles (for example, construction). Blocking of objects or terrain causes poor wireless signal transmission, and therefore often forces the communication service network (eg, GSM) to re-establish the call to reduce the interference or interruption of the call. However, the mobile phone must submit a re-establishment request to the base station for a certain period of time to re-allocate the radio resources. If the current base station is still in a shortage of radio resources, the call is forced to be interrupted.

It is worth noting that in the case of low signal strength or unstable signal, in order to send and receive wireless signals from the base station, the mobile phone must maintain communication with the base station by increasing power, which will increase power consumption, and appropriate. If the mobile phone is constantly searching for the network during the standby process, it will easily lead to unnecessary power consumption. Therefore, how to provide a method for restricting calls in the case of low signals is one of the current important issues.

In view of the above, an object of the present invention is to provide a method for limiting a call under low signal and a system thereof, which has at least one dialing standard value, so that the call request can be restricted in time according to the signal strength of the surrounding environment.

In order to achieve the above object, the present invention provides a method for restricting calls under low signals, which is applicable to a mobile communication device, and the mobile communication device has at least one dialing standard value. The method for limiting the call under the low signal includes the following steps: detecting at least one wireless signal; determining whether the strength of the wireless signal is lower than the dialing standard value, and limiting when the strength of the wireless signal is determined to be lower than the dialing standard value Call request for the mobile communication device.

In order to achieve the above object, the present invention provides a low-signal limited call system, which is applicable to a mobile communication device having at least one dialing standard value, and the low-signal limited call system includes a signal detecting module and a determining mode. Group and a switching module. The signal detection module is configured to detect the wireless signal of the communication; the determination module is coupled to the signal detection module, and the determination module determines whether the strength of the wireless signal detected by the signal detection module is lower than the dialing standard value. The switching module is coupled to the determining module. When the determining module determines that the strength of the wireless signal is lower than the dialing standard value, the switching module limits the call request of the mobile communication device according to the judgment result of the determining module.

In view of the above, a low-signal limited call method and a system for applying the same according to the strength of the wireless signal enable the mobile communication device to restrict the call in a timely and automatic manner. Compared with the prior art, the method for limiting the call under low signal and the system for applying the same disclosed in the present invention can achieve the purpose of limiting the call under the low signal without complicated operation steps.

Hereinafter, a method for restricting a call under low signal and a system for applying the same according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings, wherein like elements will be described with the same reference numerals.

Please refer to FIG. 1 , which is a flowchart of a method for restricting calls under low signal according to a preferred embodiment of the present invention, including steps S1 to S2; and in order to make the following steps clearer, the embodiment applies In the case of a mobile communication device, the mobile communication device has at least one dialing standard value.

First, step S1 is to detect at least one wireless signal; and step S2 is to determine whether the strength of the wireless signal is lower than a dialing standard value. When the strength of the wireless signal is judged to be lower than the dialing standard value, then, as shown in step S21, the call request of the mobile communication device is restricted.

Among them, the dialing standard value can be used according to actual needs, the power required by the mobile communication device to send and/or accept the call request under good signal strength, of course, the dialing standard value can also be critical to at least one base according to actual needs. Within the scope of the Taiwanese, it is not limited to this. In addition, the call request further includes the sending and receiving of the short message or the wireless Internet access, etc., but is not intended to limit the present invention.

When the wireless signal strength of the mobile communication device changes (for example, from high to low), in order to avoid excessive power consumption of the mobile communication device, some functions of the mobile communication device are restricted, for example, sending and receiving calls or text messages. . Wait for the request. In other words, the mobile communication device can limit the opening of some functions according to the strength of the sensed wireless signal.

The method for restricting calls under the low signal disclosed in the present invention can automatically determine whether the strength of the wireless signal in the environment where the mobile communication device is located is lower than the dialing standard value set therein, so as to avoid the situation of the mobile communication device in the receiving state. In the case of poor operation, it is possible to prevent the mobile communication device from being in a state of high electromagnetic wave for a long time. Moreover, when the wireless signal strength detected by the mobile communication device is determined to be greater than or equal to the dialing standard value, the call request of the mobile communication device is not restricted as shown in step S22. That is, in an environment where the wireless signal is sufficient, the function of the mobile communication device (for example, transmitting and receiving a call) can be performed normally.

Of course, the method disclosed in the present invention may need to stop the mobile communication device from determining the strength of the wireless signal, so that the call function of the mobile communication device is not limited by the influence of the environmental signal strength. That is, the low-signal mobile communication device can still perform the call request.
