Detailed ways

In order to make those skilled in the art better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments are only a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of the present invention.

When the mobile terminal re-searches the network, it first performs a system scan operation, that is, scans a plurality of historical frequency band information saved during the last successful network search, and initiates registration with the base station according to the historical frequency band information. If the valid network cannot be searched according to the above historical frequency band, the band scan operation is continued, and the current SIM (Subscriber Identification Module) is sequentially scanned according to the sequence of the PLMN (Public Land Mobile Network) list. The corresponding registered frequency band in the network system supported by the card, and the optimal frequency point on the frequency band is determined according to the scanning result, and the registration is initiated to the base station at the optimal frequency point. If the registration fails, this band corresponds to the invalid network, and continues to register with the base station at the optimal frequency of the next frequency band until a valid network is found.

It can be seen from the above-mentioned network searching process that if the network environment in which the mobile terminal is located is poor, it is necessary to search for multiple frequency bands in multiple network standards, and generate a large number of invalid scanning and registration operations. The network searching process is complicated, time-consuming and efficient. low.

The present application provides a network search method, the core idea is: before performing information interaction with a base station, first searching for an effective frequency point in the environment, and determining a target frequency point therein, and finally according to the target frequency point and the Searching the network according to the network standard corresponding to the target frequency can greatly reduce the number of interactions between the mobile terminal and the base station, thereby shortening the search time and improving the search efficiency. The present solution will be further described below in conjunction with specific embodiments and drawings.

Please refer to FIG. 1 , which is a flowchart of a network searching method according to an embodiment of the present application. The execution body of the method is a controller of the mobile terminal. As can be seen from Figure 1, the method includes the following steps:

Step S100: Acquire wireless spectrum information in an environment where the mobile terminal is located, and extract an effective frequency point from the wireless spectrum information.

In this embodiment, the wireless spectrum information in the environment can be obtained through the IQ frequency sweeping technology, and the IQ refers to the transmission circuit line in which the CPU and the RF transceiver chip transmit information in the mobile phone. Among them, the I/Q two channels are in phase with each other, and the mutual modulation is performed at 90 degrees. The specific acquisition manner of the effective frequency point in the wireless spectrum information may be: the radio frequency receiver built in the mobile terminal scans all the frequency bands in the environment where the mobile terminal is located according to the preset parameters, and records the specific frequency point of each frequency band and Signal strength; if the signal strength of the frequency point exceeds a preset threshold (such as -100dBm), the frequency point is considered to be an effective frequency point; the effective frequency point is recorded and saved in the NV (nonvolatile) area of the memory.

In the network search mode, different frequency points of each frequency band are defined by wireless standardization organizations such as 3GPP. The frequency spacing of different communication systems is not exactly the same: for example, 2G GSM (global system for mobile communication) The interval between every two adjacent frequency points of the LTE (long term evolution) of the 4G system is 5MHz, 10MHz, 15MHz, 20MHz, and the like. The mobile terminal will sequentially perform scanning and information interaction of the candidate frequency points according to the frequency point interval defined by the 3GPP, and each frequency band stores up to 50 candidate frequency points. In order to avoid the fall of the effective frequency, in the present application, the interval used by the IQ sweep can be consistent with the frequency interval specified by the 3GPP.

Step S200: It is detected whether the effective frequency point is a target frequency point of the mobile terminal search network, and in response to the effective frequency point being a target frequency point of the mobile terminal search network, step S300 is performed.

Please refer to FIG. 2 , which is a flowchart of step S200 according to an embodiment of the present application. As can be seen from FIG. 2, step S200 includes the following steps:

Step S201: Acquire a network standard supported by the user identification card in the PLMN list information built in the mobile terminal.

Step S202: Detect whether the frequency band corresponding to the network standard includes the effective frequency point, and in response to the frequency band corresponding to the network system, including the effective frequency point, perform step S203.

Step S203: Confirm the effective frequency point as a target frequency point of the mobile terminal search network.

The mobile terminal usually has built-in PLMN list information. For the list of PLMNs, please refer to Table 1. Among them, the range of frequency bands corresponding to each network standard (4G, 3G, 2G) and each access mode is included. Combined with the network standard supported by the user identification card (SIM card), the frequency range (reception) currently supported by the mobile terminal can be obtained. For example, if the SIM card currently carried by the mobile terminal is a Unicom card, the mobile terminal can directly scan from the first frequency band corresponding to the Unicom card, for example, the 4G band 3 (LTE FDD, 1765-1780 MHz) frequency band, and determine the IQ frequency sweep. Whether the effective frequency point is located in the frequency band corresponding to the Unicom card, thereby finding the target frequency point of the mobile terminal search network.

Step S300: Perform a network search according to the target frequency point and a network standard corresponding to the target frequency point.

The network search process of the mobile terminal mainly includes multiple processes such as cell search, parsing system message, cell selection, and cell camping. For example, a mobile communication network is a cellular network composed of different cells, each cell has a certain coverage, and the operating frequency and frequency band may be different. When the terminal device is rebooted, it needs to search the network again. In addition, when the location of the terminal device changes, cell handover may occur, and the mobile terminal also needs to re-determine the target frequency point and perform cell search on the target frequency point. For example, the mobile terminal may sequentially send registration request information to a base station disposed around the mobile terminal, and determine whether the mobile terminal successfully accesses the effective network according to the response information fed back by the base station. The response information carries base station information and a target frequency point corresponding to the base station information. Specifically, after the cell search network is completed, the following actions are performed: detecting PSS/SSS (primary synchronization signal, primary synchronization signal, secondary synchronization signal), and acquiring time-frequency synchronization; detecting RS (cell reference signal, reference) The signal is obtained by acquiring the frequency domain synchronization; decoding the PBCH (physical broadcast channel) to obtain the MIB (management information base); and reading the PCFICH (physical control format indication channel) to obtain the radio frame The configuration of the control domain and the data domain; obtaining the SIB (system information block), and finally completing the registration, thus completing the entire search process.

An embodiment of the present application provides a network searching method, including the following steps: acquiring wireless spectrum information in an environment where a mobile terminal is located, extracting an effective frequency point from the wireless spectrum information, and detecting whether the effective frequency point is a mobile The target frequency of the terminal search network; in response to the effective frequency point being the target frequency point of the mobile terminal search network, searching for the network according to the target frequency point and the network system corresponding to the target frequency point. The method searches for an effective frequency point in the environment before performing information interaction with the base station, and then determines a target frequency point suitable for the mobile terminal in the effective frequency point, and finally according to the target frequency point and the network standard corresponding to the target frequency point. Searching the network can greatly reduce the number of interactions between the mobile terminal and the base station, thereby shortening the search time and improving the efficiency of the search. The implementation flow of the method and the outstanding effects will be described below with reference to a specific example.

Please refer to FIG. 3 , which is a wireless spectrum diagram obtained by the IQ frequency sweep provided by the embodiment of the present application. As can be seen from Figure 3, the wireless spectrum map includes three effective frequency points, which are 1050Mhz, 1805Mhz, and 2450Mhz. Among them, 1050Mhz and 2450Mhz are not in the corresponding frequency range in the PLMN list (Table 1). Therefore, there is only 1805Mhz target frequency of a network search in the current network environment.

If the mobile terminal device initiates a registration application to all candidate frequency points in all frequency bands covered by 4G and 3G, and then returns to the 2G frequency band to apply for registration after the registration fails, multiple invalid information interactions are required, which wastes a large amount of search time. .

Through the prior IQ spectrum analysis, the application can directly obtain the effective frequency points existing in the environment, and the controller of the mobile terminal skips the system scan phase directly, and does not need to start the sweep from the Band 1 in the band scan phase. Registration can be initiated directly on the Band 3 band of 4G. If the 4G Band 3 fails to register successfully, the remaining 4G-LTE band and 3G band are skipped, and the band is directly dropped back to the band covered by 2G to initiate registration, and the registration is successful ( There is no 3G 1805Mhz band in the real network environment in China). It can be seen that the method can effectively eliminate invalid network registration, thereby optimizing the time and efficiency of the entire search operation and improving the user experience.

In a network environment, it usually includes more than one target frequency point. To this end, the present application provides a network search method for multiple target frequency points. Please refer to FIG. 4, which is a flowchart of step S300 according to an embodiment of the present application. As can be seen from FIG. 4, step S300 includes the following steps:

Step S301: detecting whether the plurality of target frequency points belong to the same network frequency band, and in response to the plurality of target frequency points not belonging to the same network frequency band, performing step S302; and responding to the multiple target frequency points belonging to the same For a network band, step S303 is performed.

Step S302: Determine a search priority order of the plurality of target frequency points according to an arrangement order of frequency bands to which each target frequency point belongs in the PLMN list information.

Step S303: Determine a search priority order of the plurality of target frequency points according to signal strengths of the plurality of target frequency points.

Step S304: Perform network search according to the search priority order of the plurality of target frequency points.

For example, the IQ sweep indicates that the surrounding base station signal has three target frequencies (located in China), which are 930MHz, 1920MHz, and 2130MHz, respectively. These three frequencies belong to Band 8 (925-960MHz) and Band 39 (1880-1920MHz). And Band 1 (2110-2170MHz). Since the above three target frequency points do not belong to the same network frequency band, the search network priority order of the plurality of target frequency points needs to be determined according to the order of the frequency bands to which the target frequency points belong in the PLMN list information. In this embodiment, the search priority order is 2130MHz (Band 1), 930MHz (Band 8), and 1920MHz (Band 39), and each target frequency point initiates registration with the base station in the order of 4G-3G-2G. In this embodiment, since there is no Band 1 and Band 39 in the 2G system, the 2G system only attempts to register in the frequency band of GSM Band 8.

In addition, in other embodiments of the present application, if the IQ frequency sweep obtains the target frequency point of the same network frequency band, the search network priority order of the target frequency point is determined according to the strength of the signal strength according to the target frequency point to ensure the movement. The terminal has a higher data transfer rate and a smoother network environment.

Although the speed of the IQ sweep is faster than the interaction between the terminal device and the base station information, it still takes up part of the search time. To this end, in other embodiments of the present application, the execution reason of the search process is confirmed first. If the network operation is performed after the mobile terminal is powered off and then restarted, the IQ sweep operation may be completed in parallel with the initialization operation of the system program. , thereby further optimizing the search efficiency of the mobile terminal.
