Background technique

With the development of the fifth generation of mobile communication technology (the 5thGeneration of Cellular Mobile Communications, 5G), electronic devices with 5G communication capabilities, such as 5G client equipment (Customer Premise Equipment, CPE), etc., are more and more used in daily life. more and more widely.

Currently, 5G networks of most operators are deployed using a non-standalone (NSA, Non-Standalone) network, for example, an option3.x NSA network is used for deployment. For a 5G network using NSA networking, electronic devices need to register with a Long Term Evolution (LTE) cell (4G cell) first, and then register with a New Radio (NR) cell (5G cell) associated with the LTE cell. Cell), in order to use the 5G network. However, not all LTE cells have an associated NR cell. That is to say, if an electronic device is registered to an LTE cell that is not associated with an NR cell within the coverage of an NR cell, the electronic device can only use the 4G network, which will affect the use of users. 5G network experience.

Contents of the invention

In view of this, an embodiment of the present application provides an electronic device, a network search method thereof, and a readable medium. By first using the historical anchor frequency of the operator of the electronic device to perform network search when the electronic device performs a network search, the anchor cell using the historical anchor frequency can be searched first, and the possibility of using 5G by the electronic device is improved.

In the first aspect, the embodiment of the present application provides a network search method, which is applied to an electronic device, and the method includes: based on multiple historical anchor frequencies in the anchor frequency band database, determine the current location of the electronic device in each cell , whether there is at least one cell whose cell frequency is the same as at least one historical anchor point frequency in a plurality of historical anchor point frequencies; Whether there is an anchor cell in the at least one cell; if there is an anchor cell in the at least one cell, register the mobile communication network of the electronic device with the determined anchor cell.

In the embodiment of the present application, when the electronic device performs a network search, it can first perform a network search based on the anchor frequency (historical anchor frequency) used by the current operator of the electronic device stored in the anchor frequency band database, and then When a cell whose frequency is the historical anchor point frequency is found, determine whether the cell is an anchor point cell, and register to the anchor point cell if the cell is an anchor point cell.

When the electronic device passes the network search method provided in the embodiment of the present application, it can first register to the anchor cell whose frequency is the historical anchor frequency, thereby increasing the possibility of the electronic device using the 5G network, and further improving the experience of the user using the 5G network . In addition, since the electronic device first conducts network search based on the historical anchor frequency instead of all frequencies supported by the electronic device or all frequencies supported by the current operator of the electronic device, the speed at which the electronic device searches for the anchor cell can be improved , and then increase the speed of electronic devices connected to the 5G network, and further enhance the user experience of using the 5G network.

In a possible implementation of the above-mentioned first aspect, the above-mentioned method further includes: when there is no anchor cell in the above-mentioned at least one cell, determining whether there is a cell with a frequency of more than A second anchor cell with a frequency other than a plurality of historical anchor frequencies; if it is determined that there is a second anchor cell whose cell frequency is a frequency other than a plurality of historical anchor frequencies, the cell frequency of the second anchor cell And the operator identification corresponding to the second anchor cell is updated to the anchor frequency band database.

That is to say, in the embodiment of this application, if the electronic device does not search for the anchor cell using the historical anchor frequency, it can also search for the anchor cell using other frequencies, so as to avoid the current operator of the electronic device The change in the frequency of deploying the anchor cell causes electronic devices to use the 4G network for data transmission when there is 5G network coverage. Moreover, when the electronic device finds the anchor cell, it can update the frequency and operator identifier corresponding to the cell to the anchor frequency band database, so that the electronic device can first search for the frequency of the anchor cell next time. The frequency of the cell increases the probability of the electronic device registering to the anchor cell, thereby increasing the possibility of the electronic device using the 5G network and the speed of searching for the anchor cell.

In a possible implementation of the above-mentioned first aspect, the above-mentioned determining whether there is an anchor cell in the at least one existing cell includes: determining whether there is an identifier of the anchor cell in the cell information of each at least one cell received by the electronic device Whether each at least one cell is an anchor cell.

For example, in some embodiments, when an operator's network equipment (such as a base station) broadcasts base station information (cell information), it will simultaneously broadcast an identifier indicating whether the cell corresponding to the base station is an anchor cell, and the electronic device can detect the base station Whether there is this identifier in the broadcast information determines whether the searched cell is an anchor cell. Specifically, the base station information broadcast by the operator's network equipment may include a system module (Master Information Block, MIB), a first system information block (System Information Block1, SIB1), a second system information block (System Information Block 2, SIB2) , where SIB2 records whether the cell corresponding to the base station is an anchor cell, for example, using the "UpperLayeIndication (ULI, upper layer indication)" field to indicate whether the cell is an anchor cell, and the electronic device can use the ULI field in SIB2 Whether the content is "true" or "false" determines whether the cell is an anchor cell.

In a possible implementation of the foregoing first aspect, the plurality of historical anchor frequencies are historical anchor frequencies of a current operator of the electronic device.

That is to say, the above-mentioned multiple historical anchor frequencies are the anchor frequencies used by the current operator of the electronic device when deploying the network.

In a possible implementation of the above first aspect, the above registering the mobile communication network of the electronic device with the determined anchor cell includes: when the network quality of the anchor cell satisfies the first preset condition, registering the electronic device The mobile communication network of the device registers with the determined anchor cell.

That is to say, when the electronic device searches for a cell using the historical anchor frequency, it registers the mobile network of the electronic device with the cell only when the network quality of the cell satisfies the first preset condition, thereby avoiding anchor frequency When the network quality of the cell is poor, the mobile network of the electronic device is registered to the cell, which affects the user experience of using the network.

In a possible implementation of the above-mentioned first aspect, the above-mentioned first preset condition includes at least one of the following conditions: the reference signal received power is greater than the power preset value; the reference signal received quality is greater than the quality preset value; the received signal The intensity indicator is greater than the intensity preset value; the signal-to-interference plus noise ratio is greater than the plus-noise ratio preset value.

That is to say, after the electronic device registers to the anchor cell, the network quality of the NR cell associated with the anchor cell satisfies the second preset condition and registers to the NR cell, so that the electronic device 40 can use the 5G network for data transmission.

In a possible implementation of the above-mentioned first aspect, the above-mentioned second preset condition includes at least one of the following conditions: the reference signal received power is greater than the power preset value; the reference signal received quality is greater than the quality preset value; the received signal The intensity indication is greater than the intensity preset value; the signal-to-interference plus noise ratio is greater than the noise plus ratio preset value; the reference signal received power of the synchronization signal is greater than the synchronization power preset value; the reference signal reception quality of the synchronization signal is greater than the synchronization quality preset value; The signal-to-interference-plus-noise ratio of the synchronization signal is greater than a preset value of the synchronization-plus-noise ratio.

In a possible implementation of the first aspect above, the electronic device determines whether there is at least The cell frequency of a cell is the same as at least one historical anchor frequency among multiple historical anchor frequencies: the current network standard of the electronic device is not a 5G network; the network parameters of the electronic device have changed; the electronic device is not currently registered to any network; the electronic device boot.

Detailed ways

Illustrative embodiments of the present application include, but are not limited to, electronic devices, methods of searching for networks therewith, and readable media.

In order to facilitate the understanding of the technical solutions of the embodiments of the present application, first, the Option3.x NSA network is used as an example to introduce the process of registering electronic devices to a 5G network using NSA networking and performing data transmission.

Fig. 1 shows a schematic structural diagram of a 5G network 00 adopting option3.x NSA networking according to some embodiments of the present application. Referring to FIG. 1 , 5G network 00 includes 4G core network 01, 4G base station 02 and 5G base station 03, wherein the dotted line indicates the transmission path of instructions, the solid line indicates the transmission path of data, and 5G base station 03 is an associated base station of 4G base station 02.

Referring to FIG. 1, it can be seen that there is no direct command transmission path between the 5G base station 03 and the electronic device 40, that is to say, the electronic device 40 is not directly registered to the NR cell 30 corresponding to the 5G base station 03 during the process of connecting to the 5G network 01. Instead, it is necessary to register to the LTE cell 20 corresponding to the 4G base station 02. When the 4G base station 02 inquires about the associated 5G base station 03, the electronic device 40 is then registered to the NR cell 30. After that, the electronic device 40 can use the 5G network 00 for data transfer. That is to say, when the electronic device 40 is connected to the 5G network using the NSA network, it needs to register with the LTE cell and the NR cell at the same time. Moreover, 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, and 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 can be understood that an LTE cell with an associated NR cell may be called an anchor cell, such as the LTE cell 20 in FIG. 2A below. The frequency used by the anchor cell can be called the anchor frequency, and when the operator deploys the 5G network, it usually uses one or more specific frequencies to deploy the anchor cell, and this part of the frequency can be called the operator's anchor frequency band .

It can be understood that the anchor frequency band used by an operator may include multiple anchor frequencies, and, in some embodiments, the anchor frequencies used by the operator in different areas may be different.

It can be understood that the structure of the NSA network shown in FIG. 1 is only an example, and the methods provided in the embodiments of the present application are also applicable to other types of NSA networks, which are not limited here.

As mentioned above, since not all LTE cells have associated NR cells, that is to say, if the electronic device first registers to an LTE cell that is not associated with the NR cell within the coverage of the NR cell, the electronic device can only use 4G The network affects the experience of users using the 5G network. For example, referring to FIG. 2A , the frequency (frequency point) of the LTE cell 10 is 2500 MHz, the frequency of the LTE cell 20 is 2600 MHz, and the NR cell 30 is an associated cell of the LTE cell 20 . When the electronic device 40 is located at point A, because the received signal strength indication (Received Signal Strength Indication, RSSI) of the LTE cell 10 is -50dB, the RSSI of the LTE cell 20 is -70dB, and the network search sequence preset by the electronic device 40 is first Use 2500MHz to search, and then use 2600MHz to search. Since both -50dB and -70dB are greater than the preset strength values preset 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 has no associated NR cell, the electronic device 40 can only use the 4G network for data transmission, which affects the user's 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 2500 MHz; when deploying the network in city B, the anchor frequency is 2600 MHz. Since the electronic device 40 frequently registers to a cell with a frequency of 2500MHz when it is in city A, the electronic device 40 will first use 2500MHz to perform a network search; Usage conditions First search for a cell with a frequency of 2500MHz, and then search for a cell with a frequency of 2600MHz. If the signal quality of the searched cell with a frequency of 2500MHz meets the preset condition, the electronic device 40 will be registered in the cell. At this time, even if the area where the electronic device 40 is located has an anchor cell whose signal quality satisfies the preset condition, the electronic device 40 will not continue to search for the network, causing the user to only use the 4G network for data transmission, which affects user experience.

For another example, referring to FIG. 2C , when a user purchases a new electronic device 40, since the electronic device 40 is preset to search in the frequency band 2000-2500MHz from small to large frequencies, when the user purchases a new electronic device 40, the operator deploys the electronic device in the area where the user is located. The frequency of the anchor cell is 2600MHz, so if the electronic device 40 first searches for a cell whose signal quality meets the preset conditions but the frequency is 2000-2500MHz, it will register to this cell, even if the area where the electronic device 40 is located has 5G network coverage, the electronic device 40 will The device 40 will not continue to search the network, causing the user to mistakenly believe that the electronic device 40 cannot connect to the 5G network, affecting user experience and causing user complaints.

In order to solve the above problems, in some embodiments, the electronic device 40 can use all the frequency bands supported by the hardware of the electronic device 40 to search for cells, and when an anchor cell is found, determine whether the network quality of the anchor cell meets the preset conditions , if satisfied, register to the anchor cell. However, using all the frequency bands supported by the hardware of the electronic device 40 to perform network search takes a long time and is slow, which affects the efficiency of the electronic device 40 for network search, thereby affecting the experience of users using the 5G network.

In some other embodiments, the electronic device 40 may also record the anchor cell and the location of the cell registered by the electronic device, and determine whether the electronic device 40 has a registered anchor cell when the electronic device 40 performs a network search. , then register in the cell. In this way, although the anchor cell that the electronic device 40 has registered in history can be registered, if there is no anchor cell that has been registered in the area where the electronic device 40 is located, the electronic device 40 may still register to a non-anchor cell first, causing the electronic device 40 to be in a non-anchor cell. Areas covered by 5G networks use 4G networks for data transmission.

The embodiment of the present application also provides a network search method. When the electronic device searches the network, it can search for the area where the electronic device is located based on the anchor frequency used by the current operator of the electronic device (hereinafter referred to as the historical anchor frequency). The cell using the historical anchor frequency, if the cell using the historical anchor frequency is searched and the cell is the anchor cell, the mobile communication network of the electronic device is registered with the anchor cell. Specifically, an anchor frequency band database can be set in the electronic device, and the anchor frequency band database that has been used by each operator in history (hereinafter referred to as the historical anchor frequency) is stored in the anchor frequency band database. Provider identification, such as PLMN (Public Land Mobile Network, public land mobile network) identification, query the historical anchor frequency of the operator from the anchor frequency band database, and first search for the cell whose frequency is the historical anchor frequency. If you search for an anchor cell during this period, you can register with the anchor cell, and register with the NR cell when the signal quality of the NR cell associated with the anchor cell meets the preset conditions, so as to use the 5G network for data transmission. In this way, the electronic device can first use the anchor frequency used by the current operator of the electronic device in the network search to increase the probability that the electronic device first searches for the anchor cell, thereby increasing the possibility of the electronic device using the 5G network performance, thereby improving the user experience of using 5G networks. In addition, since the electronic device first uses the historical anchor point frequency of the electronic device to perform the network search instead of using all the frequency bands supported by the electronic device to perform the search, the speed of the electronic device to perform the network search is improved.

For example, referring to the application scenario shown in FIG. 2D , 2600 MHz is the anchor frequency used by the operator of the electronic device 40 in history, and the frequency is stored in the anchor frequency band database of the electronic device 40 . When the electronic device 40 searches the network at point A, it will first use the historical anchor frequency of the current operator to search the network one by one, 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 can also search for the frequency first. It is the LTE cell 20 of 2600MHz, and when the RSSI of the LTE cell 20 is greater than the preset strength value, for example, when the RSSI is greater than -90dB, register to the LTE cell 20, and then register to the associated NR cell 30 of the LTE cell 20, so that the electronic device 40 can Use 5G network for data transmission. In this way, the electronic device 40 can quickly search for the anchor cell and register to the cell when the signal quality of the anchor cell meets the preset conditions. Since it is not necessary to use all the frequency bands supported by the hardware of the electronic device 40 for network search, the performance of the electronic device is improved. The speed of web searches.

It can be understood that, in some embodiments, the anchor frequency band database may be preset in a memory of the electronic device when the electronic device leaves the factory. In some other embodiments, the electronic device may modify the anchor frequency band database during the network search through 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 usage of the electronic device.

It can be understood that, in some embodiments, the electronic device can also update the anchor frequency band database from the server. In other embodiments, if the electronic device does not have an anchor frequency band database preset, the electronic device may also create a new anchor frequency band database during network search through the network search method in each embodiment of the present application during use.

It can be understood that the electronic device 40 can be any electronic device that can be connected to the 5G network using NSA networking, including but not limited to CPE, mobile phone, laptop computer, tablet computer, wearable device, etc., which is not limited in the embodiment of the present application .

The network search method provided by the embodiment of the present application is introduced below in conjunction with the structure of the CPE 40.

Fig. 4 shows a schematic flowchart of a network search method according to some embodiments of the present application. As shown in Figure 4, the process by CPE 40 as the execution subject includes the following steps.

S401: An instruction to perform a network search is detected. After the CPE 40 detects the instruction to search the network, it starts to use the method provided by the embodiment of the present application to search the network.

For example, in some embodiments, the CPE 40 detects an instruction to perform a network search when powered on. For another example, in some other embodiments, when the CPE 40 is not registered in any cell, the CPE 40 will also detect an instruction to perform a network search. For another example, in other embodiments, when CPE 40 detects changes in network parameters of CPE 40, such as Location Area Code (Location Area Code, LAC), Routing Area Code (Routing Area Code, RAC), Tracking Area Code (Tracking Area Code, TAC), network standard (such as changing from 5G to 4G) and other parameters change, it can also detect the command to perform network search.

S402: Obtain the historical anchor frequency of the current operator of the CPE 40 from the anchor frequency band database, and search the network based on the obtained historical anchor frequency. After the CPE 40 detects the instruction to search the network, according to the operator identification of the operator currently used by the CPE 40, obtain the historical anchor frequency of the operator from the anchor frequency band database, and search based on the acquired historical anchor frequency The network is the cell whose search frequency is the historical anchor frequency.

It can be understood that, in some embodiments, the historical anchor frequency of the operator may have a preset order, and the CPE 40 may search according to this order when searching for a cell whose frequency is the historical anchor frequency. Wherein, the preset order can be set according to the frequency priority set by the operator, and can also be set according to the situation of the CPE 40 historically registered cells (for example, sorted by the number of registrations of the CPE 40 from more to less), which is not limited here.

It can be understood that, in some embodiments, if the historical anchor frequency of the current operator is not included in the anchor frequency band database, skip to step S406, and use the frequency band supported by the CPE 40 to search for the network.

It can be understood that, in some embodiments, the CPE 40 can sequentially configure the frequency of the modem 461 as each historical anchor point frequency, so that the modem 461 can use the frequency in combination with the processor 41 and the antenna module 45 to perform a network search.

It can be understood that, in some embodiments, the operator identifier can be obtained from the SIM card of the CPE 40.

S403: Determine whether an anchor cell is found. If the anchor cell is found, it means that the area where the CPE 40 is located may have 5G network coverage, and go to step S404; otherwise, it means that the area where the CPE 40 is located does not have 5G network coverage or the anchor frequency used by the operator in this area is not in the anchor frequency band In the database, go to step S405.

It can be understood that, in some embodiments, even if the CPE 40 searches for a cell whose frequency is the historical anchor frequency, the cell may not be the anchor cell. For example, referring to the embodiment shown in FIG. The frequencies used by the point cells can be different. The CPE 40 stores the anchor frequency 2500MHz in the anchor frequency band database in city A, but even if a cell with a frequency of 2500MHz is found in city B, it is not an anchor cell. Therefore, when the CPE 40 searches for a cell whose frequency is the historical anchor point frequency, it can judge whether the searched cell is an anchor point cell, and step S404 when judging that the searched cell is an anchor point cell, otherwise go to Step S405.

For example, when an operator's network equipment (such as a base station) broadcasts base station information, it will simultaneously broadcast an identifier representing whether the cell corresponding to the base station is an anchor cell, and the CPE 40 can determine whether there is the identifier in the information broadcast by the base station to determine the Whether the arrived cell is an anchor cell. Specifically, the base station information broadcast by the operator's network equipment may include a system module (Master Information Block, MIB), a first system information block (System Information Block1, SIB1), a second system information block (System Information Block 2, SIB2) , where SIB2 records whether the cell corresponding to the base station is an anchor cell, for example, using the "UpperLayeIndication (ULI, upper layer indication)" field to indicate whether this cell is an anchor cell, and the CPE 40 can be based on the ULI field in SIB2 Whether the content is "true" or "false" determines whether the cell corresponding to the base station is an anchor cell.

It can be understood that, in some embodiments, when the CPE 40 determines that the searched cell using the anchor frequency in the anchor frequency database is not an anchor cell, it can also delete the history corresponding to the frequency from the anchor frequency database. Anchor frequency data. Thereby, the speed of network search performed by the CPE 40 can be improved, and the user experience can be improved.

S404: Register to the anchor cell that satisfies the first preset condition, and simultaneously register to the NR cell when the NR cell associated with the anchor cell satisfies the second preset condition. After the CPE 40 searches for the anchor cell, it judges whether the network quality of the anchor cell satisfies the first preset condition, and after the network quality of the anchor cell satisfies the first preset condition, it judges the NR associated with the anchor cell. Whether the network quality of the cell satisfies the second preset condition, and register to the NR cell at the same time when the network quality of the NR cell satisfies the second preset condition. It can be understood that after the CPE 40 is simultaneously registered to the anchor cell and the NR cell, it can use the 5G network for data transmission.

It can be understood that the first preset condition and the second preset condition are used to characterize the network quality of the anchor cell and the NR cell, and the CPE 40 registers with the anchor cell only when the network quality of the anchor cell meets the first preset condition. The network quality of the NR cell is registered to the NR cell only when the second preset condition is met, 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: Reference Signal Received Power (Reference Signal Receiving Power, RSRP) is greater than a power preset value, Reference Signal Received Quality (RSRQ, Reference Signal Receiving Quality) The quality is greater than the preset value, the RSSI is greater than the strength preset value, and the signal to interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR) is greater than the plus-noise ratio preset value. The second preset condition may include at least one of the following conditions: RSRP is greater than a power preset value, RSRQ is greater than a quality preset value, RSSI is greater than a strength preset value, SINR is greater than a noise addition ratio preset value, and the reference signal of the synchronization signal is received The power (Synchronization Signal-Reference Signal Received Power, SS-RSRP) is greater than the preset value of the synchronization power, the reference signal receiving quality of the synchronization signal (Synchronization Signal-Reference Signal Receiving Quality, SS-RSRQ) is greater than the preset value of the synchronization quality, and the synchronization signal The signal-to-interference plus noise ratio (Synchronization Signal-Signal to Interference plus Noise Ratio, SS-SINR) is greater than the preset value of the synchronization plus noise ratio.

It can be understood that the above-mentioned RSRP, RSRQ, RSSI, SINR, SS-RSRP, SS-RSRQ, and SS-SINR to characterize the network quality of the anchor cell and the NR cell are just an example, and in other embodiments, other parameters, such as registration conditions specified by operators, 4G/5G standards, and developers of electronic equipment, etc., which are not limited here.

S405: Use the frequency band supported by the CPE 40 to search the network, and update the frequency and operator identifier of the anchor cell to the anchor frequency band database when the anchor cell is found. When the CPE 40 determines in step S403 that the anchor cell is not found, it can perform a network search according to the frequency band supported by the CPE 40 hardware. If the anchor cell is found during the search, the frequency and the operator identification of the anchor cell can be updated to The anchor frequency band database, so that the CPE 40 can first search for a cell using this frequency when performing a network search next time, thereby increasing the possibility of the CPE 40 using the 5G network. For the specific process of updating the frequency and operator identifier of the anchor cell to the anchor frequency band database, reference may be made to the embodiment shown in FIG. 7 below, which will not be repeated here.

It can be understood that, in some embodiments, when the CPE 40 uses the frequency bands supported by the CPE 40 to search for the network, the search can be performed according to the sequence of frequencies preset by the operator, or according to the sequence of frequencies preset in the CPE 40.

S406: Register to a cell that satisfies the first preset condition, and simultaneously register to the NR cell when the cell is an anchor cell and the NR cell associated with the cell satisfies the second preset condition.

After CPE 40 searches the network using the frequency band supported by CPE 40, it can register to a cell whose network quality meets the first preset condition. If the cell is an anchor cell, CPE 40 can also check the network quality of the NR cell associated with the cell. After satisfying the second preset condition, register to the NR cell.

It can be understood that, in some embodiments, there are both anchor cells and non-anchor cells among the cells searched in step S405, and the CPE 40 may first determine whether the network quality of the anchor cell satisfies the first preset condition, and then determine Whether the network quality of the non-anchor cell meets the first preset condition can increase the probability of the CPE 40 registering to the anchor cell, thereby increasing the possibility of the CPE 40 using the 5G network.

It can be understood that the execution order of the steps in the embodiment shown in FIG. 4 is only an example, and in other embodiments, the execution order of the steps can also be changed, or some steps can be split or combined, which is not limited here.

It can be understood that, in some embodiments, the CPE 40 can set the priority of the historical anchor frequency in the anchor frequency band database as the first priority, so that the CPE 40 first uses the historical anchor frequency in the anchor frequency database. Search the network, and cancel the priority setting after the network search is completed, that is, restore the default network search order of the CPE 40 .

Through the network search method provided in the embodiment of the present application, when the CPE 40 performs a network search, it can first use the historical anchor frequency stored in the anchor frequency band database to search the network, which can increase the probability of the CPE 40 registering in the anchor cell, thereby improving The possibility of CPE 40 using the 5G network improves the experience of users using the 5G network. And, because CPE 40 first searches for the sub-district whose frequency is the historical anchor point frequency instead of searching for sub-districts of all frequencies supported by CPE 40, the speed of CPE 40 for network search can be improved. In addition, if the CPE 40 does not find an anchor cell when searching for a cell whose frequency is the historical anchor point frequency, it will then perform a network search through the frequency band supported by the CPE 40, and update the frequency of the cell when the anchor cell is found. The anchor frequency band database enables the CPE 40 to use the updated historical anchor frequency for network search next time when performing a network search, further improving user experience.

In order to make the technical solutions of the embodiments of the present application clearer, the process of CPE 40 performing network search is described in detail below.

Specifically, Fig. 5 shows a schematic flow chart of CPE 40 performing network search according to some embodiments of the present application. The executive body of this method is CPE 40, as shown in Figure 5, this process comprises the following steps:

S501: Detect whether the network parameters of the CPE 40 change. When the CPE 40 detects that the network parameters change, for example, the TAC changes, it indicates that the CPE 40 needs to perform a network search to ensure a stable network quality, and then go to step S503; otherwise, if the CPE 40 detects that the network parameters have not changed, then Go to step S502.

It can be 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 and so on.

S502: Judging whether the CPE 40 is searching for an anchor cell for the first time. That is, when the network parameters of CPE 40 do not change, but when CPE 40 searches for the anchor cell for the first time, it can also perform network search according to the method provided by the embodiment of the present application, and go to step S503, otherwise end this network search.

S503: Detect whether the current network of the CPE 40 is a 5G network. That is to say, if the current network of CPE 40 is a 5G network, there is no need to search for a new network and end this search; otherwise, go to step S504 and continue to use the network search method provided by the embodiment of the present application to perform a network search, so that The CPE 40 can preferentially use the 5G network.

S504: Obtain the current operator identifier of the CPE 40. The CPE 40 acquires the operator identifier of the current operator, such as the PLMN identifier, and is used to acquire the historical anchor frequency of the operator from the anchor frequency band database.

S505: Determine whether the historical anchor frequency of the operator exists in the anchor frequency band database according to the operator identifier. CPE 40 checks whether the operator's historical anchor frequency is stored in the anchor frequency band database according to the operator's identification. If it is stored, it can first use the historical anchor frequency in the anchor frequency band database to search the network, and go to step S506, otherwise, go to step S510.

S506: Obtain the historical anchor frequency of the operator. The CPE 40 obtains the operator's historical anchor frequency from the anchor frequency band database for network search.

S507: Determine whether all historical anchor frequency searches have been completed. That is to say, the CPE 40 judges whether all historical anchor frequencies of the current operator of the CPE 40 stored in the anchor frequency band database have been searched, if completed, then go to step S510, otherwise, go to S508 to continue searching.

S508: sequentially configure the historical anchor point frequency to Modem 461 to search for the anchor point 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 a network search at the configured frequency.

S509: Determine whether an anchor cell is found. The CPE 40 judges whether the anchor cell is searched, and if it is found, it means that the area where the CPE 40 is located may have 5G network coverage, and ends this network search, otherwise go to step S507 to continue the network search. For the method of judging whether the anchor cell is searched, reference may be made to step S403, which will not be repeated here.

S510: Use the frequency band supported by the CPE 40 to search the network, and update the frequency and operator identifier of the anchor cell to the anchor frequency band database when the anchor cell is found. That is to say, when the CPE 40 fails to search for the anchor cell whose frequency is the historical anchor frequency, it can use the frequency band supported by the CPE 40 to search the network. For details, refer to step S405, which is not limited here.

It can be understood that after the CPE 40 searches for the anchor cell in step S509 or step S510, it can refer to the aforementioned step S404 to first register with the anchor cell and then register with the NR cell associated with the anchor cell to use the 5G network for data transmission.

It can be understood that the execution order of the steps in the embodiment shown in FIG. 5 is only an example, and in other embodiments, the execution order of the steps can also be changed, or some steps can be split or combined, which is not limited here.

Through the network search method provided by the embodiment of the present application, the CPE 40 can first use the historical anchor frequency of the operator of the CPE 40 to perform a network search when performing a network search, thereby improving the possibility that the CPE 40 is first registered to the anchor cell, Then improve the possibility of CPE 40 using the 5G network, and improve the experience of users using the 5G network. And, because CPE 40 first searches for the sub-district whose frequency is the historical anchor point frequency instead of searching for sub-districts of all frequencies supported by CPE 40, the speed at which CPE 40 searches for the anchor point sub-district can be improved. In addition, if the CPE 40 does not find the anchor cell when searching for a cell whose frequency is the historical anchor point frequency, it can also perform a network search through the frequency band supported by the CPE 40, and update the frequency of the cell when the anchor cell is found To the anchor frequency band database, the CPE 40 can use the updated historical anchor frequency for network search next time when performing network search, further improving user experience.

The embodiment of the present application also provides a network search device, which is used to first use the operator's historical anchor point frequency to search the network when the electronic device performs a network search, thereby improving the electronic device including the device, such as CPE 40, using the 5G network. possibility.

Specifically, FIG. 6 shows a schematic structural diagram of a network search device 400 according to some embodiments of the present application. Referring to FIG. 6 , the network search device 400 includes an anchor frequency band database 401 , an anchor frequency band database maintenance module 402 , and a search module 403 . in:

The anchor frequency band database 401 is used to store the historical anchor frequency of different operators, so that the CPE 40 obtains the historical anchor frequency of the operator from the anchor frequency band database 401 according to the operator identification when searching the network by the search module 403 , and first search for the cell whose frequency is the historical anchor frequency.

In some embodiments, the developers of CPE 40 can pre-collect the anchor frequencies used by different operators and store them in the anchor frequency band database 401, and preset the anchor frequency band database 401 in the memory of the CPE 40 when the CPE 40 leaves the factory middle.

It can be understood that, in some embodiments, the CPE 40 may also obtain the anchor frequency band database 401 from the server. In some other embodiments, the CPE 40 may also create and modify the anchor frequency band database 401 during use.

The anchor frequency band database maintenance module 402 is used to maintain the anchor frequency band database 401, including but not limited to adding historical anchor frequency, deleting historical anchor frequency, and modifying historical anchor frequency. For example, when the anchor frequency band database maintenance module 402 detects the anchor frequency of a certain operator, it can be compared with the historical anchor frequency of the operator stored in the anchor frequency band database 401, if the anchor frequency band database 401 does not have The frequency is stored in the anchor frequency band database 401 with the operator identifier of the operator and the frequency. For another example, the anchor frequency band database maintenance module 402 may delete the frequency from the anchor frequency band database 401 when the operator changes the anchor frequency, for example, deletes a certain frequency.

The search module 403 is used to perform a network search based on the historical anchor frequency of the operator in the anchor frequency band database 401, and to perform a network search using the frequency bands supported by the CPE 40. When the search module 403 performs a network search, it can 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 whose frequency is the historical anchor frequency .

After the network search device 400 is deployed in the electronic equipment, for example, after being deployed in the CPE 40, the CPE 40 can first search for a cell whose frequency is the historical anchor frequency when performing a network search, so that the CPE 40 can preferentially use the 5G network and improve the user experience. The experience of using 5G network. And, when the anchor point frequency of the operator changes, the network search device 400 can also update the historical anchor point frequency of the operator, so that the anchor point frequency band database stored in the CPE 40 can be updated in time, further improving the user's ability to use the 5G network. experience.

Further, in some embodiments, the anchor frequency band database maintenance module 402 may include: an anchor frequency band detection unit 4021 , an anchor frequency band reporting unit 4022 , an anchor frequency band matching unit 4023 and an anchor frequency band maintenance unit 4024 . The following describes the process of updating the searched anchor frequency to the anchor frequency database in combination with the scenario shown in FIG. 2D and the specific structure of the anchor frequency band database maintenance module 402 .

Specifically, FIG. 7 shows a schematic diagram of an interaction process for the anchor frequency band database maintenance module 402 to update the anchor frequency band database according to some embodiments of the present application. As shown in Figure 7, the interaction process includes the following steps.

S701: Base station 02 broadcasts base station information to CPE 40.

It can be understood that the network equipment of the operator, such as the base station 02, always broadcasts the base station information of the base station 02 within the coverage of the base station 02, including but not limited to frequency band information, operator information, network parameters, etc. Electronic equipment, such as the CPE 40, can obtain operator information, frequency band information, network parameters, etc. of the base station 02 from the received information broadcast by the base station 02.

In some embodiments, the frequency band information may include the information of the anchor frequency band, such as whether the cell corresponding to the base station 02 is an identifier of the anchor cell, the anchor frequency band field including the anchor frequency, etc., so as to facilitate electronic equipment, such as the CPE 40 Determine whether the 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 detection 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, it means that the cell corresponding to the base station 02 is not an anchor cell, and this update of the historical anchor frequency ends.

For example, in the scenario shown in FIG. 2D , in the base station information broadcast by base station 02 to CPE 40, the content of the anchor frequency band field may include "2600MHz", which means that the cell corresponding to base station 02 is an anchor cell.

It can be understood that, in some other embodiments, the anchor frequency band detection unit 4021 may also determine whether the base station 02 is an anchor cell according to whether the frequency band information received from the base station 02 includes an identifier that the cell is an anchor cell, and here Do limited.

S703: The anchor frequency band detection unit 4021 analyzes the base station information, acquires the anchor frequency and the operator ID, and sends the anchor frequency and the operator ID to the anchor frequency band reporting unit 4022. The anchor frequency band detection unit 4021 analyzes the received base station information, obtains the specific anchor frequency and operator identifier, and sends them to the anchor frequency band reporting unit 4022 .

For example, in the scenario shown in FIG. 2D , the anchor frequency band detection unit 4021 analyzes the base station information broadcast by the base station 02 to obtain the operator identifier, for example, the PLMN is 46000, and the anchor frequency is 2600MHz.

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 historical anchor frequency data to generate historical anchor frequency data, and sends it to the anchor frequency band matching unit 4023.

It can be understood that, in some embodiments, a piece of historical anchor frequency data may include the following content: an operator identifier (such as a PLMN identifier), an anchor frequency, and at this time, the format in which the anchor frequency band database 401 stores historical anchor frequency data may be Operator identifier-anchor frequency, for example, "46000-2600MHz" may be used to indicate that 2600MHz is a historical anchor frequency of China Mobile ^TM .

It can be understood that, in some other embodiments, the message broadcast by the base station 20 may include MCC (Mobile Country Code, mobile country code) and MNC (Mobile Network Code, mobile network code), at this time the anchor frequency band reporting unit may combine MCC and The MNC performs a connection to generate a PLMN identifier. For example, the MCC of China is 460, the MNC of China Mobile ^TM is 00, and the PLMN of China Mobile ^TM is 46000.

S705: The anchor frequency band matching unit 4023 detects whether the received historical anchor frequency data has been stored in the anchor frequency band database 401 . The anchor frequency band matching unit 4023 detects whether there is historical anchor frequency data received in the anchor frequency band database 401, so as to determine whether the anchor frequency of the base station 02 has been stored in the anchor frequency band database 401, and if it exists, it means no The anchor frequency band database 401 needs to be updated, and this historical anchor frequency update is ended; otherwise, it means that the anchor frequency band database 401 needs to be updated, so go 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 when the anchor frequency band matching unit 4023 determines that the received historical anchor frequency data is not stored in the anchor frequency database database 401. For example, historical anchor frequency data of “46000-2600MHz” is added to the anchor frequency band database 401 .

It can be understood that, in some other embodiments, if the anchor frequency band detection unit 4021 determines that the cell corresponding to the base station 02 is not the anchor cell, it can also obtain the operator ID and frequency of the base station 02, and send it 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, if so, the anchor frequency band maintenance unit 4024 deletes the historical anchor corresponding to the frequency from the anchor frequency band database 401 frequency data. Thereby, the anchor frequency band database 401 can be updated when the operator adjusts the anchor frequency band, so as to prevent the CPE 40 from first registering with a cell using a non-anchor frequency, thereby increasing the possibility of the CPE 40 using the 5G network. In addition, 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 the CPE 40 for network search, and further improve user experience.
