For ease of understanding, the following briefly describes the terms involved in the present invention:

PLMN: Public Land Mobile Network, public land mobile network. The PLMN consists of a mobile country code MCC and a mobile network number MNC. The format is MCC-MNC, for example 460-00.

MCC: Mobile Country Code, the mobile country code used to identify the country to which the mobile user belongs. The resources of the MCC are uniformly allocated and managed by the ITU (ITU), and uniquely identify the countries to which the mobile users belong, for a total of three, for example, China is 460.

MNC: Mobile Network Code, the mobile network number used to identify the mobile network to which the mobile customer belongs. MNCs are generally assigned by the relevant telecommunications administrations of the country. The same operator can have one or multiple MNCs, but different operators cannot share the same MNC. For example, China Mobile has MNC numbers: 00, 02 and 07. The MNC number owned by China Unicom is: 01. China Telecom owns the MNC number: 03, 11.

Network standard: The type of network, such as GSM, UMTS, WCDMA, FDD-LTE, TDD-LTE, and TDL. A networked network can be provided by different operators. The PLMN codes of the same network standard network provided by different operators are different, and the same network standard network provided by the same operator may have multiple PLMN codes. For example, the PLMN codes of the GSM type network provided by China Mobile are 460-00, 460-02 and 460-07. The PLMN code of the GSM type network provided by China Unicom is 460-01.

Manual search: used to search for available networks around electronic devices, and provide a list of searched networks to users, including the network format of the searched network and the operation of the searched network. Business.

The process of manually searching the network is: Step 1, start a timer, and acquire all the network standards supported by the electronic device. Step 2: Scan the networks of each network standard in a certain order. Step 3: When all network standards of the network are scanned or scanned for more than a preset time (for example, 150 seconds), the scanning is ended, and the result of the scanning is displayed on the display device of the electronic device for User selection.

For example, electronic devices support three network standards: FDD-LTE, WCDMA, and GSM. When manually searching the network, you need to scan the three network standards in turn. When the three network standards are scanned or the scanning time exceeds a preset time (for example, 150 seconds), the scanning is ended, and the scanning result is displayed on the display device of the electronic device for the user. select.

The process of scanning a network standard network is as follows: Step a, obtaining all the frequency bands to be scanned by the network standard. In step b, each frequency band is sequentially scanned in a certain order, and the result of the scanning is stored. In step c, when all the frequency bands are scanned, it is judged that the network standard scanning is completed.

For example, the frequency bands to be scanned by FDD-LTE and TDD-LTE are B1, B3, B40, and B41. When scanning an LTE type network, B1, B3, B40, and B41 need to be scanned in a certain order. When all four bands are scanned, it is determined that the LTE type network is scanned.

A frequency band can contain multiple channels. To scan a band, you must scan each channel contained in that band in order. When scanning a channel, if there is a base station supporting the channel, the base station sends MIB information to the electronic device, and the MIB information includes the PLMN number of the network provided by the base station. For example, the PLMN number of the network is 460-03, which means that the network is routed by China Telecom provided in China. The electronic device stores the result of the scan, that is, the PLMN number of all the scanned networks, thereby obtaining the operator to which it belongs. When all channels have been scanned, it is judged that the band scanning is completed.

Referring to FIG. 1, it is a schematic diagram of an operating environment of a preferred embodiment of the system for rapid manual search of the present invention. The system 10 of the quick manual search is installed and runs in the electronic device 1 for quickly completing the manual search and providing the user with a choice. The electronic device 1 further includes, but is not limited to, a communication device 11, a processor 12, a storage device 13, and a display device 14. The electronic device 1 may be a mobile communication device such as a mobile phone. The communication device 11 is used to search for a network available around the electronic device 1, and the communication device 11 may be a radio frequency device including an antenna. The storage device 13 is configured to store program instructions, data, and the like of the system 10 of the quick manual search. The storage device 13 may be a memory of the electronic device 1, or may be an external storage device such as a smart media card (Smart Media Card), a secure digital card (Secure Digital Card), or a flash memory card (Flash Card). The display device 14 is configured to display the scanned network.

In this embodiment, the system 10 of the fast manual search network of the present invention can be divided into one or plural modules, and the one or more modules are stored in the storage device 13 and processed by one or plural. The processor 12 (which is a processor in this embodiment) is executed to complete the present invention. As shown in FIG. 1 , the system 10 of the fast manual search network of the present invention is divided into a scanning module 101, a first determining module 102, a second determining module 103, a third determining module 104, and a feedback module. 105. The module referred to in the present invention refers to a series of computer programs capable of performing a specific function, and is more suitable for describing the execution process of the software in the electronic device 1 than the program. The specific functions of the respective modules will be described below in conjunction with the flowchart of FIG. 2.

Referring to Figure 2, there is shown a flow chart of a preferred embodiment of the method of the rapid manual search of the present invention. In this embodiment, the order of execution of the steps in the flowchart shown in FIG. 2 may be changed according to different requirements, and some steps may be omitted.

When receiving the command of manual network search, in step S20, the scanning module 101 acquires all frequency bands of the network system to be scanned.

In step S21, the scanning module 101 scans a frequency band of the network system and stores the PLMN number of the scanned network.

One frequency band includes a plurality of channels, and the scanning module 101 sequentially scans the respective channels included in the frequency band through the communication device 11. If there is a base station 2 supporting the channel being scanned around the electronic device 1, the scan module 101 receives the MIB information sent by the base station 2 through the communication device 11, thereby acquiring the PLMN number of the network provided by the base station 2. The scanning module 101 stores the PLMN number of the scanned network and the network standard of the network into a PLMN table in an accumulated manner, that is, the result of the scanning. Referring to Figure 3, it is a schematic diagram of the scan results.

When all the channels included in the frequency band are scanned, the scanning module 101 determines that the frequency band scanning is completed, and executes step S22. It should be noted that when scanning the same network standard, if the PLMN number of the scanned network has been recorded in the PLMN table, the recording will not be repeated. For example, when scanning the GSM network standard, if 460-00 has been stored in the PLMN table, then this 460-00 will not be repeatedly recorded in the PLMN table.

In step S22, when a frequency band scan is completed, the first determining module 102 determines whether all frequency bands of the network standard are all scanned. If all the frequency bands of the network system are not completely scanned, step S23 is performed; if all frequency bands of the network system are all scanned, step S24 is performed. The first determining module 102 determines whether all frequency bands of the network standard are all scanned according to the obtained list of all frequency bands of the network standard and the scanned frequency band.

In step S23, the second determining module 103 determines whether the PLMN numbers of all the networks of the network system in the country where the electronic device 1 is located are scanned. If the PLMN number of all the networks supporting the network system in the country where the electronic device 1 is located is scanned, the frequency band that is not scanned by the network standard is skipped, and the next network standard is scanned, that is, step S24 is performed; If the PLMN numbers of all the networks supporting the network system in the country where the electronic device 1 is located are not all scanned, the process returns to step S21 to scan the next frequency band of the network system.

It should be noted that a storage device 13 of the electronic device 1 pre-stores a PLMN table. The PLMN table contains a list of all the network systems corresponding to all PLMN numbers of at least one country and all network standards corresponding to the respective PLMN numbers. Referring to FIG. 4, it is a schematic diagram of a PLMN table pre-stored by an electronic device. The MCC number is 460 for the China region, and the MCC number is 466 for the Taiwan region. From the PLMN table, the network standard of all networks corresponding to a certain PLMN number of a country and the operator to which the PLMN number belongs can be obtained. At the same time, the PLMN number of all networks supporting a certain network standard in a country can also be obtained. For example, the PLMN numbers of all networks supporting the GSM system are 460-00, 460-01, 460-02, and 460-07. The second judging module 103 can obtain the PLMN number of the scanned network according to the PLMN table generated by the scanning module 101 during the scanning process, thereby determining all the networks of the network system in the country where the electronic device 1 is located. Whether the PLMN number of the road is scanned. Further, the second judging module 103 determines the country in which the electronic device 1 is located based on the MCC portion of the PLMN number in the MIB information received from the base station 2.

When all frequency bands of a network system are scanned or the PLMN numbers of all networks of the network system in the country where the electronic device is located are scanned, the third determining module 104 determines in step S24. All network standards supported by the electronic device are scanned. If all the network standards supported by the electronic device are scanned, step S25 is performed; if all the network systems supported by the electronic device are not completely scanned, return to step S20 to scan the next network supported by the electronic device. Road system.

In step S25, the feedback module 105 displays the network standard of the scanned network and its operator on the display device 14 of the electronic device 1 according to the result of the scanning.

Referring to Figure 3, it is a schematic diagram of the scan results. The feedback module 105 determines that the PLMN numbers of the GSM type networks around the electronic device 1 are 460-00, 460-01, 460-02, and 460-07. Among them, 460-00, 460-02 and 460-07 are China Mobile Communications Corporation (CMCC), and 460-01 belongs to China Unicom (CU). Therefore, the feedback module 105 determines that there are two GSM type networks available around the electronic device 1: China Mobile GSM and China Unicom GSM. By analogy, operators of available networks in other network formats can be derived.

It should be noted that when the system 10 of the quick manual search starts scanning, a timer is also turned on. If the scanning process is not completed within a preset time (for example, 150 seconds), the scanning is ended and the scanning is completed. The network is displayed on the display device 14 of the electronic device 1, that is, step S25 is performed. That is, if the execution time of steps S20 to S24 exceeds the preset time, step S25 is performed.

It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to be limiting, and those skilled in the art should understand that the technical solutions of the present invention may be modified or equivalently substituted without departing from the techniques of the present invention.
