Description

Electronic device, network searching method thereof and readable medium
Technical Field
The present application relates to the field of communications technologies, and in particular, to an electronic device, a network searching method thereof, and a readable medium.
Background
With the development of the fifth generation of Mobile communication technology (5G), electronic devices with 5G communication capability, such as Customer Premise Equipment (CPE), are increasingly used in daily life.
Currently, most operators' 5G networks are deployed using Non-independent (NSA) networking, for example, using an option3.X type NSA network. For a 5G network using NSA networking, an electronic device needs to register to a Long Term Evolution (LTE) cell (4G cell) and then to a New Radio (NR) cell (5G cell) associated with the LTE cell, so that the 5G network can be used. However, not all LTE cells have associated NR cells, that is, if the electronic device is registered in an LTE cell without an associated NR cell in the coverage of the NR cell, the electronic device may only use the 4G network, which affects the experience of the user in using the 5G network.
Disclosure of Invention
In view of this, embodiments of the present application provide an electronic device, a network searching method thereof, and a readable medium. By using the historical anchor point frequency of the operator of the electronic equipment to perform network search when the electronic equipment performs network search, the anchor point cell using the historical anchor point frequency can be searched first, and the possibility that the electronic equipment uses 5G is improved.
In a first aspect, an embodiment of the present application provides a network search method, which is applied to an electronic device, and the method includes: determining whether the cell frequency of at least one cell in each cell of the current position of the electronic equipment is the same as at least one historical anchor point frequency in the historical anchor point frequencies based on a plurality of historical anchor point frequencies in an anchor point frequency band database; determining whether an anchor cell exists in at least one existing cell under the condition that the cell frequency of the at least one existing cell is determined to be the same as at least one historical anchor frequency; and under the condition that the anchor point cell exists in at least one cell, registering the mobile communication network of the electronic equipment to the determined anchor point cell.
In this embodiment of the present application, when performing network search, the electronic device may perform network search based on an anchor point frequency (historical anchor point frequency) that is used historically by a current operator of the electronic device and stored in the anchor point frequency band database, determine whether a cell with a historical anchor point frequency is an anchor point cell when the cell is searched, and register the cell with the anchor point cell when the cell is the anchor point cell.
When the electronic device passes through the network searching method provided by the embodiment of the application, the electronic device can be registered in the anchor point cell with the historical anchor point frequency, so that the possibility that the electronic device uses the 5G network is improved, and the experience of a user using the 5G network is further improved. In addition, because the electronic device performs network search based on the historical anchor frequency, instead of performing network search on all frequencies supported by the electronic device or all frequencies supported by the current operator of the electronic device, the speed of searching the anchor cell by the electronic device can be increased, the speed of connecting the electronic device to the 5G network is increased, and the experience of using the 5G network by a user is further improved.
In one possible implementation of the first aspect, the method further includes: determining whether a second anchor point cell with a cell frequency other than the plurality of historical anchor point frequencies exists in each cell of the current position of the electronic equipment under the condition that the anchor point cell does not exist in the at least one cell; and under the condition that a second anchor point cell with a cell frequency other than the plurality of historical anchor point frequencies exists, updating the cell frequency of the second anchor point cell and the operator identification corresponding to the second anchor point cell into an anchor point frequency band database.
That is to say, in the embodiment of the present application, the electronic device may also search anchor cells using other frequencies when the anchor cell using the historical anchor frequency is not searched, so as to avoid that the frequency of the anchor cell deployed by the current operator of the electronic device changes, which causes the electronic device to use a 4G network for data transmission when there is 5G network coverage. And under the condition that the electronic equipment searches the anchor point cell, the frequency and the operator identification corresponding to the cell can be updated into the anchor point frequency band database, so that the electronic equipment can search the cell with the frequency as the frequency when network searching is carried out next time, the probability that the electronic equipment is registered in the anchor point cell is improved, and the possibility that the electronic equipment uses a 5G network and the speed of searching the anchor point cell are improved.
In a possible implementation of the first aspect, the determining whether an anchor cell exists in the at least one cell includes: and determining whether each at least one cell is an anchor cell according to the identifier of whether the anchor cell exists in the cell information of each at least one cell received by the electronic equipment.
For example, in some embodiments, when broadcasting base station information (cell information), a network device (e.g., a base station) of an operator may broadcast an identifier indicating whether a cell corresponding to the base station is an anchor cell, and the electronic device may determine whether the searched cell is the anchor cell by detecting whether the identifier is in the information broadcast by the base station. Specifically, the base station Information broadcasted by the network device of the operator may include a System module (Master Information Block, MIB), a first System Information Block (System Information Block1, SIB 1), and a second System Information Block (System Information Block 2, sib2), where SIB2 records an identifier of whether a cell corresponding to the base station is an anchor cell, for example, an "upper layer indication" field is used to indicate whether the cell is an anchor cell, and the electronic device may determine whether the cell is an anchor cell according to whether the content of the ULI field in SIB2 is "true" or "false".
In a possible implementation of the first aspect, the plurality of historical anchor frequencies are historical anchor frequencies of a current operator of the electronic device.
That is, the plurality of historical anchor frequencies are anchor frequencies used by a current operator of the electronic device when deploying a network, and in some embodiments, the plurality of historical anchor frequencies may be anchor frequency bands collected by a developer of the electronic device and preset in an anchor frequency band database of the electronic device; in other embodiments, the plurality of historical anchor frequencies may also be added to the anchor frequency band database by the electronic device during use.
In a possible implementation of the first aspect, the registering a mobile communication network of the electronic device to the determined anchor cell includes: and under the condition that the network quality of the anchor point cell meets a first preset condition, registering the mobile communication network of the electronic equipment to the determined anchor point cell.
That is to say, when the electronic device searches for a cell using a historical anchor frequency, the mobile network of the electronic device is registered in the cell only when the network quality of the cell meets the first preset condition, so that the mobile network of the electronic device is prevented from being registered in the cell when the network quality of the anchor cell is poor, and the experience of a user using the network is prevented from being affected.
In a possible implementation of the first aspect, the first preset condition includes at least one of the following conditions: the reference signal receiving power is greater than a power preset value; the reference signal receiving quality is greater than a quality preset value; the received signal strength indication is greater than a strength preset value; the signal-to-interference plus noise ratio is greater than the preset value of the plus noise ratio.
In one possible implementation of the first aspect, after registering the mobile communication network of the electronic device with the determined anchor cell, the method further includes: registering the mobile communication network of the electronic device with the NR cell in case the network quality of the NR cell associated with the anchor cell satisfies a second preset condition.
That is, after the electronic device is registered to the anchor cell, the electronic device 40 may use the 5G network for data transmission by registering to the NR cell associated with the anchor cell if the network quality of the NR cell satisfies the second preset condition.
In a possible implementation of the first aspect, the second preset condition includes at least one of the following conditions: the reference signal receiving power is greater than a preset power value; the reference signal receiving quality is greater than a quality preset value; the received signal strength indication is greater than a strength preset value; the signal-to-interference plus noise ratio is greater than a preset adding noise ratio value; the reference signal receiving power of the synchronous signal is greater than the preset value of the synchronous power; the reference signal receiving quality of the synchronous signal is greater than the preset value of the synchronous quality; and the signal-to-interference plus noise ratio of the synchronous signal is greater than the preset synchronous plus noise ratio value.
In a possible implementation of the first aspect, the electronic device determines, based on a plurality of historical anchor point frequencies in the anchor point frequency band database, whether a cell frequency of at least one cell in each cell where the electronic device is currently located is the same as at least one historical anchor point frequency in the plurality of historical anchor point frequencies, where: the current network system of the electronic equipment is not a 5G network; network parameters of the electronic device change; the electronic device is not currently registered to any network; the electronic device is powered on.
That is to say, the electronic device performs the network search under the above-mentioned condition, namely, by using the network search method provided in the embodiments of the present application.
In one possible implementation of the first aspect, the network parameter includes at least one of the following parameters: cell identification, location area coding, routing area coding, tracking area coding and network system.
In a second aspect, the present application provides a readable medium, where instructions are stored, and when executed on an electronic device, the instructions cause the electronic device to implement the first aspect and any one of the network search methods provided by various possible implementations of the first aspect.
In a third aspect, an embodiment of the present application provides an electronic device, including: a memory to store instructions for execution by one or more processors of an electronic device; and a processor, which is one of the processors of the electronic device, and is configured to execute the instructions to enable the electronic device to implement the network searching method of any one of the first aspect and the various possible implementations of the first aspect.

Detailed Description
The illustrative embodiments of the present application include, but are not limited to, an electronic device and a network searching method thereof, and a readable medium.
In order to facilitate understanding of the technical solution of the embodiment of the present application, a process of registering an electronic device to a 5G network using NSA networking and performing data transmission is described by taking an option3.X type NSA network as an example.
Fig. 1 illustrates a schematic structural diagram of a 5G network 00 employing option3.X type NSA networking, according to some embodiments of the present application. Referring to fig. 1, a 5g network 00 includes a 4G core network 01, a 4G base station 02, and a 5G base station 03, in which a dotted line indicates a transmission path of an instruction, a solid line indicates a transmission path of data, and the 5G base station 03 is an associated base station of the 4G base station 02.
Referring to fig. 1, it can be seen that the 5G base station 03 and the electronic device 40 do not have a direct instruction transmission path, that is, the electronic device 40 does not directly register to the NR cell 30 corresponding to the 5G base station 03 in the process of connecting to the 5G network 01, but needs to register to the LTE cell 20 corresponding to the 4G base station 02 first, and in case that the associated 5G base station 03 is queried by the 4G base station 02, the electronic device 40 registers to the NR cell 30 again, and thereafter, the electronic device 40 can perform data transmission using the 5G network 00. That is, when the electronic device 40 is connected to the 5G network using NSA networking, it needs to be registered to both the LTE cell and the NR cell. In addition, during the data transmission process of the electronic device 40 through the 5G network 00, the uploaded data is always uploaded to the 4G core network through the 5G base station 03, the downloaded data is exchanged with the 4G core network through the 5G base station 03, and the 5G base station 03 determines whether the 4G base station 02 or the 5G base station 03 transmits the data to the electronic device 40.
It is to be appreciated that the LTE cell with the associated NR cell may be referred to as an anchor cell, such as LTE cell 20 in fig. 2A below. The frequencies used by the anchor cell may be referred to as anchor frequencies, and when an operator deploys a 5G network, the anchor cell is typically deployed using a specific frequency or frequencies, and this part of the frequencies may be referred to as the anchor frequency band of the operator.
It will be appreciated that the anchor frequency band used by one operator may include multiple anchor frequencies, and in some embodiments, the anchor frequencies used by the operator in different regions may be different.
It is understood that the structure of the NSA network shown in fig. 1 is only an example, and the methods provided by the embodiments of the present application are also applicable to other types of NSA networks, and are not limited herein.
As described above, since not all LTE cells have an associated NR cell, that is, if the electronic device is registered in an LTE cell not associated with the NR cell in the coverage of the NR cell, the electronic device may only use the 4G network, which affects the experience of the user in using the 5G network. For example, referring to fig. 2a, the frequency (frequency point) of the LTE cell 10 is 2500MHz, the frequency of the LTE cell 20 is 2600MHz, and the NR cell 30 is an associated cell of the LTE cell 20. When the electronic device 40 is located at the point a, because the Received Signal Strength Indication (RSSI) of the LTE cell 10 is-50 dB, the RSSI of the LTE cell 20 is-70 dB, and the preset network search sequence of the electronic device 40 is to search by using 2500MHz first and then search by using 2600MHz, because-50 dB and-70 dB are both greater than the preset Strength preset value in the electronic device 40, the electronic device 40 will register in the LTE cell 10 with a larger RSSI. However, since the LTE cell 10 does not have an associated NR cell, the electronic device 40 can only use the 4G network for data transmission, which affects the user experience of using the 5G network.
For another example, referring to fig. 2B, when an operator deploys a 5G network in city a, the anchor frequency is 2500MHz; when the city B carries out network deployment, the anchor frequency is 2600MHz. Since the electronic device 40 frequently registers in the cell with the frequency of 2500MHz in the city a, the electronic device 40 will use 2500MHz to perform network search first when performing network search; when the user carries the electronic device 40 to the city B, the electronic device 40 searches a cell with a frequency of 2500MHz first and then searches a cell with a frequency of 2600MHz according to the historical use condition, and if the signal quality of the searched cell with a frequency of 2500MHz meets a preset condition, the electronic device 40 registers in the cell. At this time, even if there is an anchor cell in the area where the electronic device 40 is located, where the signal quality meets the preset condition, the electronic device 40 may not continue to search for a network, which may cause the user to only use the 4G network for data transmission, which may affect user experience.
For another example, referring to fig. 2C, when a user newly purchases the electronic device 40, since the preset search sequence when the electronic device 40 leaves the factory is to search from small to large according to the frequency in the frequency band 2000-2500 MHz, but the frequency of the anchor point cell deployed by the operator in the area where the user is located is 2600MHz, if the electronic device 40 first searches for a cell whose signal quality meets the preset condition and whose frequency is 2000-2500 MHz, the cell will be registered in the cell, and even if the area where the electronic device 40 is located is covered by the 5G network, the electronic device 40 will not continue to perform network search, so that the user may mistakenly think that the electronic device 40 cannot connect to the 5G network, which affects user experience and causes user complaints.
In order to solve the above problem, in some embodiments, the electronic device 40 may search a cell using all frequency bands supported by hardware of the electronic device 40, determine whether the network quality of an anchor cell meets a preset condition when the anchor cell is searched, and register the anchor cell if the network quality of the anchor cell meets the preset condition. However, it takes a long time to perform network search using all frequency bands supported by hardware of the electronic device 40, and the speed is slow, which affects the efficiency of performing network search by the electronic device 40, and further affects the experience of the user using the 5G network.
In other embodiments, the electronic device 40 may also record anchor cells registered by the electronic device and locations of the cells, determine whether the electronic device 40 has a registered anchor cell when the electronic device 40 performs network search, and register the anchor cell in the cell if the electronic device 40 has the registered anchor cell. As such, although the anchor cell that has been registered in the history of the electronic device 40 can be registered, if the area where the electronic device 40 is located does not have the anchor cell that has been registered, the electronic device 40 may first register with the non-anchor cell, which may cause the electronic device 40 to use the 4G network for data transmission in the area covered by the 5G network.
The embodiment of the application further provides a network searching method, when the electronic device searches a network, the electronic device may search a cell using the historical anchor frequency in an area where the electronic device is located based on the anchor frequency used by the current operator of the electronic device in the history (hereinafter referred to as the historical anchor frequency), and register the mobile communication network of the electronic device with the anchor cell when the cell using the historical anchor frequency is searched and the cell is the anchor cell. Specifically, an anchor frequency band database may be set in the electronic device, where anchor frequencies that have been used by each operator in history (hereinafter referred to as history anchor frequencies) are stored in the anchor frequency band database, and when the electronic device searches for a Network, according to an operator identifier, for example, a PLMN (Public Land Mobile Network) identifier, the electronic device queries the history anchor frequencies of the operator from the anchor frequency band database, and searches for a cell with a frequency as the history anchor frequency. During the period, if the anchor cell is searched, the anchor cell can be registered, and when the signal quality of the NR cell associated with the anchor cell meets the preset condition, the NR cell can be registered, so that the 5G network is used for data transmission. Therefore, when the electronic equipment carries out network search, the anchor point frequency used by the current operator history of the electronic equipment can be used firstly for carrying out network search, the probability that the electronic equipment searches anchor point cells firstly is improved, the possibility that the electronic equipment uses the 5G network is improved, and the experience that a user uses the 5G network is further improved. In addition, when the electronic device performs network search, the historical anchor frequency of the electronic device is used for network search first instead of all frequency bands supported by the electronic device, so that the speed of the electronic device for network search is increased.
For example, referring to the application scenario shown in fig. 2D, 2600MHz is an anchor frequency that has been used historically by an operator of the electronic device 40, and the anchor frequency band database of the electronic device 40 stores the frequency. When searching for a network at point a, the electronic device 40 may first perform network search one by one using the historical anchor point frequency of the current operator, so that even if the signal strength of the LTE cell 10 is greater than the strength of the LTE cell 20, the electronic device 40 may first search for the LTE cell 20 with the frequency of 2600MHz, and register the LTE cell 20 with the relevant NR cell 30 of the LTE cell 20 when the RSSI of the LTE cell 20 is greater than a preset strength value, for example, the RSSI is greater than-90 dB, so that the electronic device 40 may perform data transmission using a 5G network. Therefore, the electronic device 40 can quickly search for the anchor cell and register in the anchor cell when the signal quality of the anchor cell meets the preset condition, and the network search speed of the electronic device is increased because the network search is performed without using all frequency bands supported by the hardware of the electronic device 40.
It will be appreciated that in some embodiments, the anchor frequency band database may be pre-stored in the memory of the electronic device at the time of shipment of the electronic device. In other embodiments, the electronic device may modify the anchor frequency band database during network search by using the network search method of the embodiment of the present application, so that the anchor frequency band database may be updated according to the actual use condition of the electronic device.
It is to be appreciated that in some embodiments, the electronic device may also update the anchor frequency band database from a server. In other embodiments, if the anchor frequency band database is not preset in the electronic device, the electronic device may also newly establish the anchor frequency band database in the process of performing network search by using the network search method according to the embodiments of the present application.
It is understood that the electronic device 40 may be any electronic device capable of connecting to a 5G network using NSA networking, including but not limited to CPE, cell phone, laptop, tablet, wearable device, etc., and the embodiments of the present application are not limited thereto.
The following description will take the electronic device 40 as the CPE 40 as an example.

It is understood that the structure of the CPE 40 shown in fig. 3 is only an example, and in other embodiments, the CPE 40 may include more or fewer modules, or may combine or split some of the modules, which is not limited herein.
The network searching method provided by the embodiment of the present application is described below with reference to the structure of CPE 40.
Fig. 4 illustrates a flow diagram of a network search method, according to some embodiments of the present application. As shown in fig. 4, the flow by the CPE 40 as the execution subject includes the following steps.
S401: an instruction to perform a network search is detected. CPE 40, upon detecting the instruction to perform a network search, begins to search for a network using the methods provided by embodiments of the present application.
For example, in some embodiments, CPE 40 detects an instruction to perform a network search when it is powered on. For another example, in other embodiments, CPE 40 may also detect an instruction to perform a network search when CPE 40 is not registered with any cell. For another example, in another embodiment, the CPE 40 may also detect the instruction for performing the network search when detecting a change of a network parameter of the CPE 40, for example, a change of a parameter such as a Location Area Code (LAC), a Routing Area Code (RAC), a Tracking Area Code (TAC), a network type (for example, a change from 5G to 4G), and the like.
S402: and acquiring the historical anchor point frequency of the current operator of the CPE 40 from the anchor point frequency band database, and searching the network based on the acquired historical anchor point frequency. After detecting the instruction for network search, the CPE 40 obtains the historical anchor frequency of the operator from the anchor frequency band database according to the operator identifier of the operator currently used by the CPE 40, and searches for a network based on the obtained historical anchor frequency, that is, a cell whose search frequency is the historical anchor frequency.
It will be appreciated that in some embodiments, the operator's historical anchor frequencies may have a predetermined order in which CPEs 40 may search when searching for cells having a frequency that is the historical anchor frequency. The preset sequence may be set according to a frequency priority specified by an operator, or may be set according to a situation that the CPE 40 registers the cell historically (for example, the CPE 40 registers the cell in a descending order), and is not limited herein.
It is understood that in some embodiments, if the historical anchor frequency band of the current operator is not included in the anchor frequency band database, the method may skip to step S406 to search for a network using the frequency band supported by CPE 40.
It is to be appreciated that in some embodiments, CPE 40 may in turn configure the frequency of modem 461 to historical anchor frequencies, such that modem 461 may use the frequency in conjunction with processor 41, antenna module 45 for network searching.
It will be appreciated that in some embodiments, the operator identity may be obtained from a SIM card of CPE 40.
S403: and judging whether the anchor point cell is searched. If the anchor cell is searched, it indicates that there may be 5G network coverage in the area where the CPE 40 is located, and go to step S404; otherwise, it indicates that the area where the CPE 40 is located does not have 5G network coverage or the anchor frequency used by the operator in the area is not in the anchor frequency band database, and then go to step S405.
It is to be appreciated that in some embodiments, the CPE 40 may not be an anchor cell even if it searches for a cell with a frequency of the historical anchor frequency, for example, referring to the embodiment shown in fig. 2B, the frequencies used by anchor cells deployed by operators in different cities may be different, and the CPE 40 stores the anchor frequency 2500MHz in the anchor frequency band database in city a, but does not be an anchor cell even if it searches for a cell with a frequency of 2500MHz in city B. Therefore, when searching for a cell with a frequency of the historical anchor frequency, the CPE 40 may determine whether the searched cell is an anchor cell, and step S404 if the searched cell is determined to be the anchor cell, otherwise, step S405.
For example, when broadcasting the information of the base station, the network device (e.g., the base station) of the operator may broadcast an identifier indicating whether the cell corresponding to the base station is the anchor cell, and the CPE 40 may determine whether the searched cell is the anchor cell by detecting whether the identifier is in the information broadcast by the base station. Specifically, the base station Information broadcasted by the network device of the operator may include a System module (Master Information Block, MIB), a first System Information Block (System Information Block1, SIB 1), and a second System Information Block (System Information Block 2, sib2), where SIB2 records an identifier of whether a cell corresponding to the base station is an anchor cell, for example, an "upper layer indication" field is used to indicate whether the cell is an anchor cell, and CPE 40 may determine whether the cell corresponding to the base station is an anchor cell according to whether the content of the ULI field in SIB2 is "true" or "false".
It is to be understood that, in some embodiments, in the case that the searched cell using the anchor frequency in the anchor frequency band database is determined not to be an anchor cell, the CPE 40 may further delete the historical anchor frequency data corresponding to the frequency from the anchor frequency band database. Therefore, the network searching speed of the CPE 40 can be increased, and the user experience is improved.
S404: and registering to an anchor point cell meeting a first preset condition, and simultaneously registering to an NR cell when the NR cell associated with the anchor point cell meets a second preset condition. After searching the anchor point cell, the CPE 40 determines whether the network quality of the anchor point cell satisfies a first preset condition, determines whether the network quality of the NR cell associated with the anchor point cell satisfies a second preset condition after the network quality of the anchor point cell satisfies the first preset condition, and registers the NR cell when the network quality of the NR cell satisfies the second preset condition. It can be appreciated that CPE 40 can use the 5G network for data transmission after registering with the anchor cell and the NR cell.
It can be understood that the first preset condition and the second preset condition are used for characterizing the network quality of the anchor point cell and the NR cell, and the CPE 40 registers to the anchor point cell only when the network quality of the anchor point cell satisfies the first preset condition and registers to the NR cell only when the network quality of the NR cell satisfies the second preset condition, so that the network quality of the CPE 40 can be ensured.
In some embodiments, the first preset condition may include at least one of the following conditions: the Reference Signal Receiving Power (RSRP) is greater than a Power preset value, the Reference Signal Receiving Quality (RSRQ) is greater than a Quality preset value, the RSSI is greater than a strength preset value, and the Signal to Interference plus Noise Ratio (SINR) is greater than a Noise plus Noise Ratio preset value. The second preset condition may include at least one of the following conditions: the RSRP is greater than a Power preset value, the RSRQ is greater than a Quality preset value, the RSSI is greater than a strength preset value, the SINR is greater than a Noise Ratio preset value, the Reference Signal-Reference Signal Received Power (SS-RSRP) of the synchronous Signal is greater than a synchronous Power preset value, the Reference Signal-Reference Signal Receiving Quality (SS-RSRQ) of the synchronous Signal is greater than a synchronous Quality preset value, and the Signal-to-Interference plus Noise Ratio (SS-SINR) of the synchronous Signal is greater than a synchronous Noise Ratio preset value.
It is understood that the above-mentioned characterization of the network quality of the anchor cell and the NR cell by RSRP, RSRQ, RSSI, SINR, SS-RSRP, SS-RSRQ, SS-SINR is only an example, and in other embodiments, other parameters may be used for characterization, for example, by registration conditions specified by an operator, a 4G/5G standard, a developer of an electronic device, and the like, which is not limited herein.
S405: the frequency bands supported by CPE 40 are used to search the network and, when an anchor cell is searched, the frequency and operator identification of the anchor cell are updated to the anchor frequency band database. In step S403, when determining that the anchor cell is not searched, CPE 40 may perform network search according to a frequency band supported by hardware of CPE 40, and in the meantime, if the anchor cell is searched, the frequency and the operator identifier of the anchor cell may be updated to the anchor frequency band database, so that CPE 40 may search for a cell using the frequency first when performing network search next time, thereby improving the possibility that CPE 40 uses a 5G network. The specific process of updating the frequency and the operator identifier of the anchor point cell to the anchor point frequency band database may refer to the embodiment shown in fig. 7, which is not described herein again.
It can be understood that, in some embodiments, in the process that the CPE 40 searches for a network using a frequency band supported by the CPE 40, the search may be performed according to a frequency sequence preset by an operator, or may be performed according to a frequency sequence preset in the CPE 40.
S406: registering to a cell meeting a first preset condition, and simultaneously registering to an NR cell when the cell is an anchor cell and an NR cell associated with the cell meets a second preset condition.
After searching for a network using the frequency band supported by the CPE 40, the CPE 40 may register to a cell whose network quality satisfies a first preset condition, and if the cell is an anchor cell, the CPE 40 may also register to an NR cell associated with the cell after the network quality of the NR cell satisfies a second preset condition.
It can be understood that, in some embodiments, in the cells searched in step S405, there are both anchor cells and non-anchor cells, and CPE 40 may first determine whether the network quality of the anchor cell meets a first preset condition, and then determine whether the network quality of the non-anchor cell meets the first preset condition, so as to improve the probability that CPE 40 registers in the anchor cell, and further improve the possibility that CPE 40 uses a 5G network.
It is to be understood that the execution sequence of the steps in the embodiment shown in fig. 4 is only an example, and in other embodiments, the execution sequence of the steps may be changed, and partial steps may be split or combined, which is not limited herein.
It is understood that, in some embodiments, CPE 40 may set the priority of the historical anchor frequency in the anchor frequency band database to the first priority, so that CPE 40 may first search for a network using the historical anchor frequency in the anchor frequency band database, and cancel the priority setting after the network search is completed, that is, restore the default network search order of CPE 40.
By the network searching method provided by the embodiment of the application, when the CPE 40 searches the network, the historical anchor point frequency stored in the anchor point frequency band database can be used for searching the network, so that the probability that the CPE 40 registers in an anchor point cell can be improved, the possibility that the CPE 40 uses the 5G network can be further improved, and the experience of a user using the 5G network can be improved. In addition, since the CPE 40 searches for a cell having a frequency of the historical anchor frequency first instead of searching for cells of all frequencies supported by the CPE 40, the speed of network search by the CPE 40 may be increased. In addition, if the anchor point cell is not searched when the CPE 40 searches for a cell with a historical anchor point frequency, network search is performed through a frequency band supported by the CPE 40, and the frequency of the cell is updated to the anchor point frequency band database when the anchor point cell is searched, so that the CPE 40 can perform network search using the updated historical anchor point frequency first when performing network search next time, and user experience is further improved.
In order to make the technical solution of the embodiment of the present application clearer, the following describes the process of network searching for the CPE 40 in detail.
Specifically, fig. 5 shows a schematic flow diagram of CPE 40 performing a network search, according to some embodiments of the present application. The main execution subject of the method is CPE 40, as shown in fig. 5, the process includes the following steps:
s501: it is detected whether a change in network parameters of CPE 40 has occurred. When the CPE 40 detects that the network parameter changes, for example, the TAC changes, which indicates that the CPE 40 needs to perform network search to ensure stable network quality, step S503 is performed, otherwise, if the CPE 40 detects that the network parameter does not change, step S502 is performed.
It is understood that the network parameters include, but are not limited to, LAC, RAC, TAC, network standard, RSRP, RSRQ, RSSI, SINR, SS-RSRP, SS-RSRQ, SS-SINR, etc.
S502: it is determined whether CPE 40 is the first search anchor cell. That is, when the network parameters of the CPE 40 are not changed, but the CPE 40 performs the search for the anchor point cell for the first time, the method provided in the embodiment of the present application may also perform the network search, and go to step S503, otherwise, the network search is ended.
S503: it is detected whether the current network of the CPE 40 is a 5G network. That is, if the current network of the CPE 40 is a 5G network, the search for a new network is not required, and the search is ended; otherwise, go to step S504 to continue to use the network search method provided in the embodiment of the present application to perform network search, so that CPE 40 can preferentially use the 5G network.
S504: the current operator identification of CPE 40 is obtained. CPE 40 obtains an operator identification, e.g., a PLMN identification, of the current operator for obtaining a historical anchor frequency for the operator from an anchor frequency band database.
S505: and determining whether the historical anchor point frequency of the operator exists in the anchor point frequency band database according to the operator identification. The CPE 40 queries whether the historical anchor frequency of the operator is stored in the anchor frequency band database according to the operator identifier, and if so, may first perform network search using the historical anchor frequency in the anchor frequency band database, and then go to step S506, otherwise, go to step S510.
S506: and acquiring the historical anchor frequency of the operator. CPE 40 obtains the historical anchor frequency for the operator from the anchor frequency band database for network searching.
S507: and judging whether the search of all historical anchor point frequencies is finished. That is, the CPE 40 determines whether all historical anchor frequencies of the current operator of the CPE 40 stored in the anchor frequency band database have been searched, and if so, goes to step S510, otherwise, goes to step S508 to continue the search.
S508: and sequentially configuring the historical anchor frequency to the Modem 461 to search the anchor cell. The CPE 40 sequentially configures the historical anchor frequencies obtained from the anchor frequency band database into the Modem 461, so that the Modem 461 can perform network search at the configured frequencies.
S509: and judging whether the anchor point cell is searched. The CPE 40 determines whether to search for the anchor point cell, and if so, indicates that there may be 5G network coverage in the area where the CPE 40 is located, and ends the network search, otherwise, the process goes to step S507 to continue the network search. The method for determining whether to search for the anchor cell may refer to step S403, which is not described herein.
S510: the frequency bands supported by CPE 40 are used to search the network and, when an anchor cell is searched, the frequency and operator identification of the anchor cell are updated to the anchor frequency band database. That is to say, when the CPE 40 fails to search the anchor cell having the historical anchor frequency, the CPE 40 may search the network using the frequency band supported by the CPE 40, which may specifically refer to step S405, and this is not limited herein.
It is understood that, after the CPE 40 searches for the anchor cell in step S509 or step S510, it may refer to step S404 to register to the anchor cell and then register to the NR cell associated with the anchor cell, so as to use the 5G network for data transmission.
It is to be understood that the execution sequence of the steps in the embodiment shown in fig. 5 is only an example, and in other embodiments, the execution sequence of the steps may be changed, and partial steps may be split or combined, which is not limited herein.
By the network searching method provided by the embodiment of the application, the CPE 40 can firstly use the historical anchor point frequency of the operator of the CPE 40 to carry out network searching when carrying out network searching, so that the possibility that the CPE 40 registers in the anchor point cell firstly is improved, the possibility that the CPE 40 uses the 5G network is further improved, and the experience of a user using the 5G network is improved. Also, since the CPE 40 searches for a cell having a frequency of the historical anchor frequency first rather than searching for cells of all frequencies supported by the CPE 40, the speed at which the CPE 40 searches for an anchor cell may be increased. In addition, if the anchor point cell is not searched when the CPE 40 searches for a cell with a historical anchor point frequency, the CPE 40 may perform network search through a frequency band supported by the CPE 40, and update the frequency of the cell to the anchor point frequency band database when the anchor point cell is searched, so that the CPE 40 can perform network search using the updated historical anchor point frequency first when performing network search next time, thereby further improving user experience.
Embodiments of the present application further provide a network searching apparatus, configured to search a network using a historical anchor frequency of an operator when an electronic device performs a network search, so as to improve a possibility that the electronic device including the apparatus, for example, CPE 40, uses a 5G network.
Specifically, fig. 6 shows a schematic structural diagram of a network searching apparatus 400 according to some embodiments of the present application. Referring to fig. 6, the network search apparatus 400 includes an anchor frequency band database 401, an anchor frequency band database maintenance module 402, and a search module 403. Wherein:
the anchor frequency band database 401 is configured to store historical anchor frequencies of different operators, so that when the CPE 40 searches for a network through the search module 403, the CPE obtains the historical anchor frequency of the operator from the anchor frequency band database 401 according to the operator identifier, and searches for a cell having a frequency as the historical anchor frequency.
In some embodiments, a developer of the CPE 40 may collect anchor frequency bands used by different operators in advance and store the anchor frequency bands in the anchor frequency band database 401, and preset the anchor frequency band database 401 in a memory of the CPE 40 when the CPE 40 is shipped from a factory.
It is understood that in some embodiments, CPE 40 may also obtain anchor frequency band database 401 from a server. In other embodiments, CPE 40 may also create and modify the anchor frequency band database 401 during its use.
The anchor frequency band database maintenance module 402 is configured to maintain the anchor frequency band database 401, including but not limited to increasing the historical anchor frequency, deleting the historical anchor frequency, and modifying the historical anchor frequency. For example, when detecting an anchor frequency of a certain operator, the anchor frequency band database maintenance module 402 may compare the anchor frequency with a historical anchor frequency of the operator stored in the anchor frequency band database 401, and store an operator identifier of the operator and the frequency in the anchor frequency band database 401 if the anchor frequency band database 401 does not have the frequency. For another example, anchor frequency band database maintenance module 402 may delete an anchor frequency band from anchor frequency band database 401 when an operator changes the anchor frequency band, for example, deletes the frequency band.
The search module 403 is configured to perform a network search based on the historical anchor frequency of the operator in the anchor frequency band database 401 and perform a network search using the frequency band supported by the CPE 40. When performing network search, the search module 403 may obtain the historical anchor frequency of the operation from the anchor frequency band database 401 according to the operator identifier of the operator currently used by the CPE 40, and first search for a cell with the historical anchor frequency.
After the network searching apparatus 400 is deployed in the electronic device, for example, after the network searching apparatus is deployed in the CPE 40, the CPE 40 may first search for a cell with a frequency as a historical anchor frequency when performing network search, so that the CPE 40 may preferentially use a 5G network, and the experience of a user using the 5G network is improved. Moreover, when the anchor frequency of the operator changes, the network search apparatus 400 may also update the historical anchor frequency of the operator, so that the anchor frequency band database stored in the CPE 40 may be updated in time, and the experience of the user in using the 5G network is further improved.
Further, in some embodiments, the anchor frequency band database maintenance module 402 may include: the anchor frequency band detection unit 4021, the anchor frequency band reporting unit 4022, the anchor frequency band matching unit 4023 and the anchor frequency band maintenance unit 4024. The following describes a process of updating the searched anchor frequency to the anchor frequency database, with reference to the scene shown in fig. 2D and the specific structure of the anchor frequency database maintenance module 402.
Specifically, fig. 7 is a schematic diagram illustrating an interaction flow of the anchor frequency band database maintenance module 402 updating the anchor frequency band database according to some embodiments of the present application. As shown in fig. 7, the interaction flow includes the following steps.
S701: base station 02 broadcasts base station information to CPE 40.
It is understood that the network device of the operator, such as the base station 02, always broadcasts the base station information of the base station 02, including but not limited to frequency band information, operator information, network parameters, etc., within the coverage of the base station 02. The electronic device, for example, the CPE 40 may obtain the operator information, the frequency band information, the network parameters, and the like of the base station 02 from the received information broadcast by the base station 02.
In some embodiments, the frequency band information may include information of an anchor frequency band, for example, an identifier of whether a cell corresponding to the base station 02 is an anchor cell, an anchor frequency band field including an anchor frequency, and the like, so that the electronic device, for example, the CPE 40, determines whether a cell corresponding to the base station 02 is an anchor cell according to the frequency band information.
S702: the anchor frequency band detection unit 4021 determines whether the cell corresponding to the base station 02 is an anchor cell based on the base station information. For example, the anchor frequency band detecting unit 4021 may determine that the cell corresponding to the base station 02 is the anchor cell when detecting that the content of the anchor frequency band field in the frequency band information received from the base station 02 is not empty, and go to step S703, otherwise, indicate that the cell corresponding to the base station 02 is not the anchor cell, and end the current historical anchor frequency update.
For example, in the scenario shown in fig. 2D, in the base station information broadcasted by the base station 02 to the CPE 40, the content of the anchor frequency band field may include "2600MHz", that is, it may be described that the cell corresponding to the base station 02 is an anchor cell.
It can be understood that, in other embodiments, the anchor frequency band detecting unit 4021 may further determine whether the base station 02 is the anchor cell according to whether the frequency band information received from the base station 02 includes the identifier that the cell is the anchor cell, which is not limited herein.
S703: the anchor frequency band detection unit 4021 analyzes the base station information, acquires the anchor frequency and the operator identifier, and sends the anchor frequency and the operator identifier to the anchor frequency band reporting unit 4022. The anchor frequency band detection unit 4021 analyzes the received base station information, acquires a specific anchor frequency and an operator identifier, and transmits the anchor frequency band information to the anchor frequency band reporting unit 4022.
For example, in the scenario shown in fig. 2D, the anchor frequency band detecting unit 4021 parses the base station information broadcast by the base station 02 to obtain an operator identifier, for example, 46000 for PLMN and 2600MHz for anchor frequency.
S704: the anchor frequency band reporting unit 4022 associates the anchor frequency with the operator identifier to generate historical anchor frequency data, and sends the historical anchor frequency data to the anchor frequency band matching unit 4023. That is, the anchor frequency band reporting unit 4022 associates the anchor frequency band of the base station 02 with the operator identifier according to the format in which the anchor frequency band database 401 stores the historical anchor frequency data to generate historical anchor frequency data, and sends the historical anchor frequency data to the anchor frequency band matching unit 4023.
It will be appreciated that in some embodiments, a piece of historical anchor frequency data may include the following: the format of the anchor frequency band database 401 storing the historical anchor frequency data may be the carrier identifier-anchor frequency, for example, "46000-2600MHz" may indicate that 2600MHz is china mobile TM A historical anchor frequency.
It is to be understood that, in other embodiments, the message broadcasted by the base station 20 may include an MCC (Mobile Country Code) and an MNC (Mobile Network Code), and at this time, the anchor frequency band reporting unit may connect the MCC and the MNC to generate the PLMN identifier. For example, MCC 460 in China, china Mobile TM MNC of 00, china moves TM And 46000 for PLMN.
S705: the anchor frequency band matching unit 4023 detects whether the anchor frequency band database 401 stores the received historical anchor frequency data. The anchor frequency band matching unit 4023 detects whether there is received historical anchor frequency data in the anchor frequency band database 401 to determine whether the anchor frequency of the base station 02 has been stored in the anchor frequency band database 401, and if so, it indicates that the anchor frequency band database 401 does not need to be updated, and this update of the historical anchor frequency is finished; otherwise, it indicates that the anchor frequency band database 401 needs to be updated, so the process goes to step S706.
S706: the anchor frequency band maintenance unit 4024 updates the anchor frequency band database 401. That is, the anchor frequency band maintenance unit 4024 updates the received historical anchor frequency data to the anchor frequency band database 401 when the anchor frequency band matching unit 4023 determines that the received historical anchor frequency data is not stored in the anchor frequency band database. For example, historical anchor frequency data of "46000-2600MHz" is added to the anchor frequency band database 401.
It can be understood that, in other embodiments, if the anchor frequency band detection unit 4021 determines that the cell corresponding to the base station 02 is not an anchor cell, the operator identifier and the frequency of the base station 02 may also be obtained and sent to the anchor frequency band matching unit 4023, the anchor frequency band matching unit 4023 determines whether the anchor frequency is recorded in the anchor frequency band database 401, and if so, the anchor frequency band maintenance unit 4024 deletes the historical anchor frequency data corresponding to the anchor frequency from the anchor frequency band database 401. Therefore, the anchor frequency band database 401 can be updated under the condition that the operator adjusts the anchor frequency band, so that the condition that the CPE 40 registers to a cell using non-anchor frequency first is avoided, and the possibility that the CPE 40 uses a 5G network is further improved. Moreover, deleting the historical anchor frequency data corresponding to the non-anchor frequency from the anchor frequency band database 401 can also increase the speed of network search performed by the CPE 40, thereby further improving user experience.
