If the multi-mode mobile phone only supports the GSM system and the CDMA system, the GSM system and the key number of the CDMA system can be classified as 'when the user dials the number, the corresponding communication system can be selected according to the key number in the dialed number. call. It is worth noting that since the multi-mode mobile phone does not support the PHS system, in order to allow the user to use the best tariff scheme when dialing the number of the PHS system, this embodiment also includes the PHS system and GSM 200913646 / V respectively. i 1Z-. JL vy 24618twf.doc/n The comparison between the system and the CDMA system tariff scheme to select the communication system with better call tariff scheme and classify the key number of the PHS system as the selected communication system. In detail, if the cost of the call between the PHS system and the GSM system is lower, the key numbers PH7 and 〇〇〇8 of the PHS system are classified into the GSM system; otherwise, if the PHS system and the CDMA system are The cost of making a call is lower - the key numbers of the PHS system 〇〇〇7, 〇〇〇8 are classified into the CDMA system, and so on. Accordingly, when the number dialed by the user includes the key number of the PHS system, the pre-categorized communication system (GSM system or CDMA system) can be used to make a call and save the call. However, the above embodiments are merely illustrative and are not intended to limit the scope of the practical application of the present invention. In addition, before establishing the number classification information, the user can input or update manually, update the key number corresponding to each communication system in the portable communication device, or update the communication system supported and unsupported by the portable communication device. The tariff between the two makes the key number established in the number classification information keep up-to-date and the most sophisticated settings. Next, in step S120, the multi-standby mode is entered so that these communication systems stand by at the same time. In the case of a GSM/CDMA dual-mode handset, the GSM system and the CDMA system are both on standby. β, then, in step sm, the dial-out number ' is received by the portable communication device for making a call, such as manually input by the user, or the user selects from the phone book of the portable communication device And its scope. 200913646, T 24618twf.doc/n Finally, after the portable communication device receives the dialed number, as shown in step S140, the number classification information can be referred to, and the communication system corresponding to the key number of the dialed number is selected to dial. Out the number. In addition, according to the length of the dialed number, from the number classification information, the communication system corresponding to the dialed number is selected to dial the dialed number. For example, in the case of a GSM/CDMA dual-mode mobile phone, if the key number of the dialed number is 0001', the number classification information can be referred to and the communication system corresponding to the key number 〇〇〇1 is selected for dialing. It is worth mentioning that after selecting the communication system corresponding to the dial-out number, it is also possible to decide whether to use the communication system according to the signal strength to improve the call quality. The portable communication device can first determine whether the signal strength of the communication system corresponding to the dialed number is less than a preset value. When it is less than the preset value, it is selected from the number classification information to use other communication systems (for example, the communication system with the lowest tariff) to dial. It is worth noting that in practical applications, in order to save power, most users set the multimode mobile phone in the single standby mode, and only use one of the communication systems to stand by, and the following embodiment illustrates the single standby mode call. method. 2 is a flow chart of a method for automatically switching a communication system according to a dialed number according to another embodiment of the present invention. Referring to FIG. 2, first, in step S210, number classification information is established. This step is the same as or similar to step S110 of the above embodiment, and therefore will not be described here. Then, as shown in step S220, the single standby mode is entered, and one of the communication systems is selected to stand by. In other words, the communication system of the pre-amp; in the single standby mode is set to the standby state. For example, in the GSM/CDMA dual 11 200913646 „ „ 24618 twf.doc/n mobile phone, if the GSM system is a preset communication system in the single standby mode, the GSM system is set to the standby state, and the CDMA system is temporarily not turned on. Then, in step S230, the dialed number is received by the portable communication device. Thereafter, as shown in step S240, referring to the number classification information, the communication system corresponding to the key number of the dialed number is selected for dialing. Secondly, in step S250, the portable communication device will determine whether the communication system currently in standby is the pass-k system corresponding to the key number of the dial-out number, wherein, since the portable communication device uses the single standby mode, Therefore, only one communication system is in the standby state, and it is necessary to determine whether the standby communication system is the communication system corresponding to the key number of the dialed number. If yes, execute step S260 to directly dial the dialing using the currently standby communication system. Exit the number; otherwise, execute step S27〇, start the communication system corresponding to the key number of the dialed number, to dial the dial After the call is completed, as shown in step S280, the communication system in which the single standby mode was originally standby is restored. For example, in the GSM/CDMA dual-mode mobile phone using the GSM system standby, if the key of the dialed number is judged If the number is GSM system, the GSM system can be used for dialing directly. Otherwise, if the key number of the dialed number is CDMA system, the CDMA system will be activated to dial the number. After the call is over, the CDMA system will be closed. Revert to the single standby mode of the GSM system standby. It is worth mentioning that this embodiment selects and uses the dialed number corresponding to 12 200913646 ----------- 24618twf.doc/n After that, it is further determined whether to use the communication system according to the intensity of the k, in order to improve the call quality, which is similar to the above embodiment, and the details thereof will not be described herein. On the other hand, in addition to the multi-standby mode and In addition to the single standby mode, the communicable communication device can enter the forced mode to directly dial the dialed number using the communication system of the forced module. That is, the user can root, the environment Other factors, the portable communication device is set to a strong type, so when dialing, the forced mode preset is used as the first one; dialing. ° Cheng ·, first of all, the above embodiment According to the key number of the dialed number, the corresponding communication system is selected to dial the number, and the user can automatically switch to the most suitable communication system without the need for fine operation. In addition, the same communication system is used for the call. The tariff will be cheaper than the system, so the method of the invention can not only reduce the delay, but also the quality of the call, and save the cost of the call. Although the invention has been disclosed above in the preferred embodiment, It is not intended to limit the invention, and any person having ordinary skill in the art, in the spirit and scope of the invention, may make some modifications and refinements.
