Detailed Description
In order to make the purpose, technical solution, and technical effects of the present application clearer and clearer, the following further describes the present application in detail, and it should be understood that the specific embodiments described herein are only used for explaining the present application, and are not used for limiting the present application.
Referring to fig. 1, fig. 1 is a schematic flowchart of a network connection method provided in an embodiment of the present application, where the network connection method is applied to a mobile terminal, and a specific flow may be as follows:
s101: when the mobile terminal needs to perform network connection again, a plurality of frequency bands supported by the mobile terminal are obtained, and the working frequency band of the base station which is supported by the mobile terminal and accessed is determined.
In this embodiment, the mobile terminal may be any device with internet access function, such as a mobile phone, a tablet computer, a notebook computer, a palm computer, a personal digital assistant, a portable media player, a navigation device, a wearable device, an intelligent watch, an intelligent bracelet, and a pedometer, and includes at least one antenna, such as a high frequency main antenna, a low intermediate frequency upper main antenna, or a low intermediate frequency lower main antenna, wherein each antenna can transmit signals using at least one communication system (e.g., WCDMA, FDD LTE, TDD LTE, etc.), and when one antenna transmits signals using one communication system, the frequency band of the transmitted signal can be selected correspondingly, taking the main antenna on the low intermediate frequency as an example, when the main antenna on the low intermediate frequency transmits the signal by using the WCDMA communication system, the frequency band of the corresponding signal may be B1, B2, B3, B4, B5, B6, B8, or the like.
Specifically, when the mobile terminal needs to perform network connection again, the antenna identifier of the antenna currently used by the mobile terminal and the used communication system may be obtained, and a plurality of working frequency bands corresponding to the antenna identifier under the used communication system are searched from the correspondence pre-stored in the mobile terminal according to the obtained antenna identifier, so as to obtain a plurality of frequency bands supported by the mobile terminal.
In some embodiments, in order to determine an operating frequency band of a base station that a mobile terminal supports access to, the S101 may specifically include:
s1011: and receiving electromagnetic wave signals transmitted by peripheral base stations.
Specifically, as shown in fig. 2, when the mobile terminal B is located in the serving cell a of the network to be connected, it can receive electromagnetic wave signals transmitted by the base stations a1, a2, and A3 (i.e., peripheral base stations) of the serving cell a.
S1012: and determining the working frequency band of the base station which supports the access of the mobile terminal based on the received electromagnetic wave signal.
Specifically, when the number of the base stations of the serving cell is one, that is, the number of the peripheral base stations is one, the frequency band of the electromagnetic wave signal transmitted by the peripheral base station may be directly used as the operating frequency band of the base station to which the mobile terminal supports access. Further, when the number of the base stations of the serving cell is multiple (for example, as shown in fig. 2, the serving cell a has three base stations a1, a2 and A3), that is, the number of the peripheral base stations is multiple, the S1012 may include:
s1-1: and determining the peripheral base station corresponding to the electromagnetic wave signal with the maximum signal intensity in the received electromagnetic wave signals as a target base station.
S1-2: and taking the frequency band of the electromagnetic wave signal transmitted by the target base station as the working frequency band of the base station which supports the access of the mobile terminal.
Therefore, the peripheral base station with the maximum intensity of the electromagnetic wave signal received by the mobile terminal is used as the target base station, so that the maximum network speed can be obtained after the subsequent mobile terminal establishes network connection with the target base station, and the internet access performance of the mobile terminal is improved.
In some alternative embodiments, in order to determine the operating frequency band of the base station that the mobile terminal supports accessing, the S101 may also specifically include: acquiring current position information of a mobile terminal; searching an accessible base station closest to the mobile terminal by using a navigation application installed on the mobile terminal according to the obtained position information; and acquiring the working frequency band of the accessible base station closest to the mobile terminal so as to obtain the working frequency band of the base station which is supported to be accessed by the mobile terminal.
S102: and sequencing the plurality of frequency bands according to the frequency size, and taking the frequency band at the middle sequencing position as a middle frequency band.
Specifically, the plurality of frequency bands may be sorted in a descending order or a descending order of frequency. Moreover, when the plurality of frequency bands are odd frequency bands, for example, (2N +1) frequency bands, where N is a natural integer not less than 1, the frequency band at the middle sorting position may be the frequency band with the sequence number of (N +1) after sorting. When the plurality of frequency bands are even number of frequency bands, for example, 2N frequency bands, where N is a natural integer not less than 1, the frequency band at the middle sorting position may be a frequency band with a serial number N or (N +1) after sorting.
S103: and comparing the frequency of the working frequency band with the frequency of the middle frequency band to obtain a comparison result.
Specifically, when comparing the frequency of the operating frequency band with the frequency of the middle frequency band, the center frequency of the operating frequency band may be directly compared with the center frequency of the middle frequency band, when the center frequency of the operating frequency band is the same as the center frequency of the middle frequency band, the comparison result may be that the frequency of the operating frequency band is the same as the frequency of the middle frequency band, when the center frequency of the operating frequency band is greater than the center frequency of the middle frequency band, the comparison result may be that the frequency of the operating frequency band is greater than the frequency of the middle frequency band, and when the center frequency of the operating frequency band is less than the center frequency of the middle frequency band, the comparison result may be that the frequency of the operating frequency band is less than the frequency of the middle frequency band.
S104: and performing network connection according to the comparison result.
As shown in fig. 3, the S104 may specifically include:
s1041: and when the comparison result indicates that the frequency of the working frequency band is the same as the frequency of the intermediate frequency band, performing network connection through the intermediate frequency band.
S1042: and when the comparison result indicates that the frequency of the working frequency band is greater than the frequency of the middle frequency band, taking the frequency band of which the frequency is greater than the frequency of the middle frequency band as an undetermined frequency band, updating the frequency bands by using the undetermined frequency band, and then returning to execute the step S102.
S1043: and when the comparison result indicates that the frequency of the working frequency band is less than the frequency of the middle frequency band, taking the frequency band of which the frequency is less than the frequency of the middle frequency band as an undetermined frequency band, updating the frequency bands by using the undetermined frequency band, and then returning to execute the step S102.
Specifically, when the plurality of frequency bands are sorted in the order of frequencies from high to low in the previous step S102, the frequency band corresponding to the frequency greater than the middle frequency band is a frequency band whose sequence number is before the sequence number of the middle frequency band after the sorting, and the frequency band corresponding to the frequency less than the middle frequency band is a frequency band whose sequence number is after the sequence number of the middle frequency band after the sorting. When the plurality of frequency bands are sorted in the order of increasing frequency in the previous step S102, the frequency band corresponding to the frequency greater than the middle frequency band is a frequency band whose sequence number is located after the sequence number of the middle frequency band, and the frequency band corresponding to the frequency less than the middle frequency band is a frequency band whose sequence number is located before the sequence number of the middle frequency band after the sequence.
Thus, the above S102, the above S103 and the above S1042, and the above S102, the above S103 and the above S1042 form two cycles, and once one of the two cycles, the number of the corresponding frequency bands to be detected is reduced by half until a frequency band matching the operating frequency band of the base station that the mobile terminal supports to access is found, so that more time consumption for performing connection detection on multiple frequency bands supported by the mobile terminal can be saved, and the network connection speed can be increased.
In some embodiments, as shown in fig. 3, before S101, the method may further include:
s105: and B, monitoring whether the running state of the mobile terminal is a preset running state, wherein the preset running state comprises starting, restarting, closing a flight mode, switching cells or inserting a Subscriber Identity Module (SIM), if so, executing the step B, and if not, not processing.
S106: and determining that the mobile terminal needs to perform network connection again.
Specifically, when the mobile terminal is powered on, restarted or turned off in the flight mode, the mobile terminal is triggered to perform network connection because the mobile terminal is not connected to the network. In the using process of the mobile terminal, when a subscriber identity module (e.g. an SIM) card is inserted into the mobile terminal, the mobile terminal is triggered to perform network connection by using the inserted subscriber identity module; or, when a user moves a mobile terminal from one serving cell to another serving cell, the network speed of the mobile terminal is greatly reduced or even the network is disconnected due to cell handover, and therefore, the mobile terminal is triggered to perform network connection.
Different from the prior art, the network connection method of the embodiment is applied to the mobile terminal, and when the mobile terminal needs to perform network connection again, the multiple frequency bands supported by the mobile terminal are obtained, the working frequency band of the base station which the mobile terminal supports to access is determined, then the multiple frequency bands are sequenced according to the frequency size, the frequency band in the middle sequencing position is used as the middle frequency band, then the frequency of the working frequency band is compared with the frequency of the middle frequency band to obtain a comparison result, and network connection is performed according to the comparison result, so that when the mobile terminal needs to perform network connection again, connection detection on all LTE frequency bands supported by the mobile terminal is not needed, the time for the mobile terminal to connect to the network can be shortened, and the internet access efficiency is improved.
