Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The network searching method of the 5G communication module can be applied to an application environment shown in fig. 1. Communication is performed between the terminal 102 and the 5G communication module 104, wherein the terminal 102 may be, but is not limited to, various personal computers, notebook computers, smartphones, tablet computers, and portable wearable devices. The present application terminal 102 will be described with respect to a host computer.
The subscriber identity card 106 is inserted into the 5G communication module 104, and the 5G communication module 104 with the subscriber identity card 106 inserted therein is inserted into the terminal 102, so that the terminal 102 can realize the data service function of the subscriber identity card 106.
In one embodiment, as shown in fig. 2, a network searching method for a 5G communication module is provided, and the method is applied to the terminal in fig. 1 for illustration, and includes the following steps:
step S202, reading the international mobile subscriber identity of the subscriber identity module, and determining the operator to which the subscriber identity module belongs according to the international mobile subscriber identity.
The international mobile subscriber identity (i.e., imsi, international Mobile Subscriber Identity) is an identity that is not repeated in all cellular networks for distinguishing between different subscribers in the cellular network. According to the international mobile subscriber identity information, the 5G communication module can learn the operators affiliated to the current subscriber identity card, such as telecom, mobile and Unicom.
Step S204, searching for networks in the frequency spectrum range corresponding to the operator according to the prestored frequency spectrum planning information of the operator, wherein the prestored frequency spectrum planning information of the operator comprises the frequency spectrum range corresponding to the operator.
The carrier frequency spectrum planning information is prestored in the 5G communication module and comprises each carrier and the corresponding frequency spectrum range thereof. Taking a 5G network system as an example, a 5G test frequency resource with the total bandwidth of 3400MHz-3500MHz and the total bandwidth of 100MHz is obtained in domestic China telecom, and a 5G test frequency resource with the total bandwidth of 260MHz in 2515MHz-2675MHz and 4800MHz-4900MHz is obtained in China mobile, wherein 2515-2575MHz, 2635-2675MHz and 4800-4900MHz are newly added frequency bands.
Specifically, after determining the operator to which the subscriber identity module belongs according to the international mobile subscriber identity, the 5G communication module performs network searching in the spectrum range corresponding to the operator, without performing network searching in the full frequency band. For example, when it is determined that the operator is china telecommunication, taking the 5G network system as an example, the spectrum range searched correspondingly is 3400MHz-3500MHz. In addition, it should be noted that in the conventional technology, after the 5G module is inserted into the subscriber identity module, only the frequency point information of the operator corresponding to the subscriber identity module cannot be directly scanned, but full-band scanning is required.
In step S206, when the effective frequency point information is searched in the corresponding frequency spectrum range, the effective frequency point information resides in the residence network corresponding to the effective frequency point information.
The effective frequency point information refers to that the 5G communication module can reside in a resident network corresponding to the frequency point information, so that a host computer realizes the data service function of the user identification card based on the resident network. The frequency point information includes a current band (radio band), ARFCN (Absolute Radio Frequency Channel Number), an absolute radio frequency channel number, and the like.
Specifically, when the 5G communication module searches for effective frequency point information in the corresponding frequency spectrum range, the 5G communication module can reside in the corresponding residence network according to the effective frequency point information. The 5G module and the host computer interact information through MBIM messages (Mobile Broadband Interface Model, which refers to an interface standard), the MBIM unifies the interface standards of mobile broadband devices (USB data card/network card and the like, NGFF data card and the like) and PC ends, and is a standard protocol. And the 5G communication module and the host computer interact control information and data information through an MBIM channel, so that the host computer realizes related data service functions.
Step S208, based on the resident network, the host computer realizes the data service function of the user identification card.
The subscriber identity module card generally has the functions of SMS, PB short message, dialing, module information inquiry, SIM card and the like.
Specifically, the subscriber identity module card is mounted on the host computer through the 5G communication module, and when the 5G communication module resides in a corresponding residence network based on effective frequency point information, the host computer interacts with the 5G communication module, so that functions of SMS, PB short message, dialing, module information query, SIM card and the like of the subscriber identity module card can be realized.
In the network searching method of the 5G communication module, the 5G communication module improves the operation manager to which the user identification card is read and determined to belong. And searching the network in the frequency spectrum range corresponding to the operator according to the prestored frequency spectrum planning information of the operator. When effective frequency point information is searched in a corresponding frequency spectrum range, the 5G communication module resides in a resident network corresponding to the effective frequency point information, and based on the resident network, the host computer realizes the data service function of the user identification card. After the operators are determined, the 5G communication module only searches the frequency point information in the frequency spectrum range corresponding to the operators, and the full frequency range of each operator is not required to be searched, so that the efficiency of the network searching process of the 5G communication module can be improved.
In one embodiment, the 5G communication module stores a configuration file; searching the network in the frequency spectrum range corresponding to the operator comprises the following steps:
acquiring current position information, comparing the position information with historical resident positioning information, and respectively calculating distance values between the position information and each piece of historical resident positioning information, wherein paired positioning information and frequency point information of a historical resident network are stored in the configuration file in advance, and the historical resident network is a historical resident network corresponding to frequency point planning information of a corresponding operator; respectively taking the obtained distance values as key values, and sequencing the key values according to the sequence from small to large of the distance values to obtain a key value sequence; and scanning the corresponding frequency point information according to the key value sequence.
The current location information refers to current location information of the 5G communication module, where the location information includes location longitude and latitude information (including longitude and latitude information). The location information is acquired by an acquisition/control chip in the 5G communication module.
The location information of the historical residence refers to the location information corresponding to the historical residence network. The historical resident network is a historical resident network corresponding to the frequency point planning information of the corresponding operator. For the same user identification card, the same 5G communication module is always inserted for use, or different user identification cards are inserted into the same 5G communication module for use. The former operator is used for determining the frequency point information corresponding to the resident network where the corresponding 5G communication module resides, and the frequency point information is always in the frequency spectrum range of the operator. In the latter case, the network in which the 5G communication module resides may be in the spectrum of multiple operators. The historical residence network mainly considers the adaptation condition of the former, and for the latter, the current latest inserted user identification card is used as the reference, when the user identification card inserted in the history and the latest inserted user identification card belong to the same operator, the frequency point information where one or more user identification cards inserted in the history reside can be used as the frequency point information where the history resides, the resident positioning information is used as the positioning information where the history resides, and the positioning information and the frequency point information where the history resides are stored in pairs. The paired positioning information and the frequency point information of the historical resident network are stored in the configuration file of the 5G communication module.
Specifically, the positioning information comprises positioning longitude and latitude information (including longitude and latitude information), the acquired position information and the positioning information of each history residence are compared, namely the acquired position longitude and latitude information and the positioning longitude and latitude information of each history residence are compared, and the distance value between the position information of the current 5G communication module and the positioning information of each history residence is obtained through calculation respectively.
A key sequence means that there are a plurality of key values arranged in an order therebetween. Since there are a plurality of historic residence networks, there are a plurality of corresponding historic residence positioning information, and there are a plurality of distance values calculated from the current position information and each historic residence positioning information. And sequencing the key values according to the sequence from the small distance value to the large distance value by taking the plurality of distance values as the key values respectively, so as to obtain a key value sequence. Therefore, the key value sequence is a plurality of distance value sets obtained by arranging the distance values in order from smaller to larger. Every time the configuration file obtains positioning information and frequency point information of a history residence, a corresponding distance value is newly obtained in the key value sequence, the newly-increased distance value is sequenced, and the key values in the key value sequence are always sequenced from small to large, so that the method is a continuously updated and dynamic process.
After the key value sequence is obtained, the 5G communication module scans the key value sequence according to the sequence of distance values, namely, the key value in other key value sequences is scanned from the minimum distance value or the forefront minimum/sequence in the key value sequence, and the distance value corresponds to the distance value, so that the positioning information of historical residence and the frequency point information of historical residence appear and are stored in pairs, the key value indirectly corresponds to the frequency point information of historical residence, and the process of scanning the key value sequence can be regarded as the process of scanning the frequency point information of historical residence.
In this embodiment, by acquiring the location information of the 5G communication module, calculating the distance value between the location information and each historical resident location information, respectively using each distance value as a key value, sorting each key value in order from small to large to obtain a key value sequence, wherein the key value with the higher sorting in the key value sequence is the key value with the higher priority as the distance from the current 5G communication module is closer, and the higher priority is the key value, the higher priority is the key value to be scanned by the 5G communication module in the scanning process, so that the 5G communication module can obtain the needed frequency point information more quickly and is resident in the resident network corresponding to the frequency point information.
In one embodiment, scanning the corresponding frequency point information according to the key value sequence sequentially includes:
checking whether the minimum key value in the key value sequence is larger than a preset threshold value or not; if the minimum key value is not greater than the preset threshold value, determining frequency point information corresponding to the minimum key value as effective frequency point information; and if the minimum key value is larger than the preset threshold value, selecting a target key value according to the key value sequence, and taking frequency point information corresponding to the target key value as effective frequency point information, wherein the target key value is the key value which is closest to the minimum key value and is not larger than the preset threshold value.
The preset threshold is a distance threshold set by the 5G communication module. If the 5G communication module is originally used at a location, the paired location information and the frequency point information at a are stored in the configuration file in the residing network corresponding to the frequency point information at a, and become the smallest key value A1 in the latest key value sequence in the process of ordering the key value sequence. The latter 5G communication module is used at the B, where the distance from the B is far from the a, and the key value A1 in the key value sequence is still the smallest key value, but the frequency point information corresponding to the key value A1 cannot be obtained at the B, so that the frequency point information corresponding to the smallest key value A1 is not valid at this time, the frequency point information does not conform to the residence condition, the 5G communication module cannot reside in the frequency point information, and then other key values after the A1 are required to be scanned. Aiming at the situation, the accuracy of network searching of the 5G communication module can be improved by setting a preset threshold value.
Specifically, if the minimum key value is not greater than the preset threshold value, it is indicated that the frequency point information corresponding to the minimum key value accords with the residence condition of the 5G communication module residence network, and the frequency point information is effective frequency point information. At this time, the 5G communication module sends out an attach request signaling, and when an attach accept message sent by the network side based on the attach request signaling is obtained, the bearer is successfully activated, and the 5G communication module successfully hosts the network.
If the minimum key value is larger than the preset threshold value, the frequency point information corresponding to the minimum key value is not in accordance with the resident condition, and the frequency point information is not effective frequency point information. The 5G communication module continues to search and select a new key value from the key value sequence as a target key value, wherein the target key value is the key value closest to the minimum key value and is not more than a preset threshold value and meets the residence condition, so that the frequency point information corresponding to the target key value is used as effective frequency point information, and the 5G communication module can reside in the residence network corresponding to the frequency point information based on the frequency point information corresponding to the target key value.
In this embodiment, by checking whether the minimum key value is greater than a preset threshold, when the minimum key value is not greater than the preset threshold according to the checking result, it is determined that the minimum key value meets the residence condition, and the 5G communication module can reside in the residence network corresponding to the frequency point information. By setting the preset threshold, the network searching accuracy of the 5G communication module can be improved.
In one embodiment, after the step of residing in the residing network corresponding to the valid frequency point information, the method further includes: and storing the paired positioning information and the frequency point information of the resident network in a configuration file.
Specifically, when the 5G communication module resides in a residence network corresponding to certain frequency point information in a frequency spectrum range of a corresponding operator, the frequency point information and the corresponding positioning information are stored in a configuration file inside the 5G communication module in a self-learning manner.
In this embodiment, the 5G communication module stores the frequency point information and the positioning information of the resided network in the configuration file through self-learning, so that the subsequent direct search is convenient, and the effective frequency point information is quickly found to carry out network residency.
In one embodiment, the network searching method of the 5G communication module further includes: and uploading the paired positioning information and the frequency point information stored in the configuration file to a server through an over-the-air downloading technology, and storing the paired positioning information and the frequency point information by the server.
The over-the-air technology (OTA transmission) is a technology for implementing remote management of mobile terminal equipment and SIM card data through an air interface of mobile communication.
Specifically, a 5G communication module uploads paired positioning information and frequency point information stored in a configuration file of the 5G communication module to a server through an over-the-air downloading technology, and the paired positioning information and frequency point information are stored in the server. The 5G communication module and other 5G communication modules can directly download and obtain required data from a server when the data support is required later. The present application employs over-the-air techniques for transmission, but is not limited to this approach alone.
In the embodiment, the paired positioning information and the paired frequency point information are uploaded to the server, and the server is used for archiving, so that the server and other 5G communication modules can be directly obtained for use, and the network searching efficiency of the 5G communication module is improved to a certain extent.
In one embodiment, the network searching method of the 5G communication module further includes:
sending a request for downloading the paired positioning information and the frequency point information to the server; acquiring the paired positioning information and frequency point information sent by the server in response to the request; and searching the network according to the paired positioning information and the frequency point information.
The request for downloading the paired positioning information and frequency point information is an electric signal, and the information contained in the electric signal enables the server to know, so that the 5G communication module communicating with the electric signal needs to obtain the paired positioning information and frequency point information.
Specifically, a request for downloading paired positioning information and frequency point information is sent to a server by a 5G communication module, and the server receives and responds to the request. More of the paired positioning information and frequency point information is needed, and the 5G communication module with less or no stored information in the configuration file can be generally understood as a newly used 5G communication module. After receiving and responding to the request, the server pairs the positioning information and the frequency point information to the 5G communication module. After a large amount of paired positioning information and frequency point information are obtained, the 5G communication module searches the network according to the information.
In this embodiment, the newly used 5G communication module downloads and obtains the paired positioning information and the paired frequency point information from the server, so that the paired positioning information and the paired frequency point information can be obtained quickly, thereby being beneficial to the quick network searching of the newly used 5G communication module.
In one embodiment, as shown in fig. 3, the network searching method of the 5G communication module includes:
step S302, the international mobile subscriber identity of the subscriber identity module is read, and the operator to which the subscriber identity module belongs is determined according to the international mobile subscriber identity.
Step S304, current position information is acquired.
Step S306, comparing the position information with the positioning information of the historic residents, and respectively calculating the distance value between the position information and the positioning information of each historic residents, wherein the paired positioning information and the frequency point information of the historic residents are stored in the configuration file in advance, and the historic residents are historic residents corresponding to the frequency point planning information of the corresponding operators;
step S308, each obtained distance value is used as a key value, and the key values are sequenced according to the sequence from the small distance value to the large distance value, so as to obtain a key value sequence;
step S310, checking whether the minimum key value in the key value sequence is larger than a preset threshold value.
If the minimum key value is not greater than the preset threshold value, step S312 is executed, and the frequency point information corresponding to the minimum key value is determined as effective frequency point information; if the minimum key value is greater than the preset threshold value, step S314 is executed, where a target key value is selected according to the key value sequence, the frequency point information corresponding to the target key value is used as the effective frequency point information, and the target key value is the key value closest to the minimum key value and not greater than the preset threshold value.
After step S312 is performed, when valid frequency point information is searched in the corresponding frequency spectrum range, step S316 is performed to reside in the resident network corresponding to the valid frequency point information.
Step S318, based on the resident network, the host computer realizes the data service function of the user identification card.
In this embodiment, the 5G communication module improves the operator to which the subscriber identity module is read to determine that the subscriber identity module belongs. And searching the network in the frequency spectrum range corresponding to the operator according to the prestored frequency spectrum planning information of the operator. When effective frequency point information is searched in a corresponding frequency spectrum range, the 5G communication module resides in a resident network corresponding to the effective frequency point information, and based on the resident network, the host computer realizes the data service function of the user identification card. After the operators are determined, the 5G communication module only searches the frequency point information in the frequency spectrum range corresponding to the operators, and the full frequency range of each operator is not required to be searched, so that the efficiency of the network searching process of the 5G communication module can be improved.
