Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the accompanying claims.
Fig. 1 is a flowchart illustrating a cell registration method according to an exemplary embodiment, which is used in a mobile terminal as shown in fig. 1, and includes the steps of:
step S11, searching whether a cell supporting a second type network registered by a first type network exists or not based on the frequency point information of the registered cell stored in a preset cell database;
here, the mobile terminal may be any mobile terminal capable of wireless communication, for example, a cellular phone, a smart watch, an in-vehicle terminal, or a Machine-To-Machine (M2M) device, or the like.
The first type of network and the second type of network may be networks that use different communication schemes or different communication protocols for mobile communication. For example, the first type of network may be a 5G communication network and the second type of network may be a 4G communication network.
The procedure of the first type network registration may be a procedure in which the mobile terminal acquires configuration information for communication through the first type network in the first type network. Here, the configuration information may include frequency point information of frequency points used for communication through the first type network. For example, the procedure of the first type network registration may be a procedure in which the mobile terminal acquires frequency point information for communication through the first type network in the first type network.
Here, the cells of the second type network include cells of the second type network supporting registration of the first type network and cells of the second type network not supporting registration of the first type network. For example, cells of the second type of network include 4G cells supporting 5G registration and 4G cells not supporting 5G registration.
The cell of the second type network supporting the registration of the first type network may be a cell capable of providing communication configuration information for the first type network communication. Here, the cells of the second type network may load the communication information by means of signaling and send it to the mobile terminal.
Here, during the mobile terminal moving, as the position of the mobile terminal changes continuously, the mobile terminal switches between different cells, and the registered cells may refer to different cells that the mobile terminal registers during the moving. For example, the mobile terminal sequentially passes through A, B, C three different area locations, sequentially switches from cell 1 to cell 2 and from cell 2 to cell 3 at A, B, C, and registers in the corresponding cell. When the mobile terminal enters the next cell from cell 3, cell 1, cell 2 and cell 3 are all cells to which the terminal is registered.
Here, the preset cell database may be a storage area corresponding to a mobile terminal, where the storage area is used to store frequency point information of a cell that has been registered in a mobile terminal moving process. The frequency point information may be stored in a "first in first out" manner based on a stack. For example, if the capacity of the stack is set to be 10, the stack can sequentially store frequency point information corresponding to 10 cells, when the number of the frequency point information exceeds 10, the frequency point information stored first in the stack is deleted, and the latest acquired frequency point information is stored in the stack, so that the frequency point information is updated continuously. Here, searching is performed based on the frequency point information of the registered cell, rather than the full frequency band, so that the searching efficiency of the mobile terminal can be improved and the searching success rate can be improved. Here, the frequency point information of the registered cell may further include frequency point information of a cell of a second type network that does not support registration of the first type network, so as to register the cell of the second type network that does not support registration of the first type network.
Here, the frequency bin information may include at least one of the following information: mobile country code (MCC, mobile Country Code), mobile network code (MNC, mobile Network Code), communication system, frequency point value, and frequency point registration success number.
For example, the mobile country code corresponding to the chinese area is 460, the mobile network code corresponding to the chinese mobile operator is 01, the mobile network corresponding to the chinese group operator is 02, the frequency point value is 5230, etc. Here, searching whether a cell supporting a second type network registered by the first type network exists may include: and according to the frequency point information (such as the area where the mobile terminal is located, the operator network supported by the mobile terminal, the communication system supported by the mobile terminal, the frequency point value and the like), sequentially searching cells of the second type network supporting the first type network registration on each frequency point value, and determining whether the cells of the second type network supporting the first type network registration exist.
Step S12, when the cell of the second type network supporting the first type network registration is searched, the first type network registration is completed in the cell of the second type network supporting the first type network registration.
Here, the cell searching for the second type network supporting the first type network registration may be searching for the cell carrying the second type network supporting the first type network registration identifier in the cell of the second type network. The method comprises the steps that first-type network registration is completed in a cell supporting a second-type network of the first-type network registration, frequency point information of the cell of the first-type network can be acquired by the cell supporting the second-type network, and the frequency point information is sent to a mobile terminal in a signaling mode, so that the mobile terminal accesses the first-type network to perform wireless communication based on the frequency point information of the first-type network.
In the embodiment of the disclosure, based on the frequency point information of the registered cells stored in the preset cell database, searching whether the cells supporting the second type network registered by the first type network exist or not, so that the full-frequency scanning of the cells supporting the second type network registered by the first type network can be omitted because the frequency point information of the registered cells exists in the preset cell database, and the first type network registration can be performed through the second type network quickly and reliably only based on the frequency point information of the registered cells in the preset cell database; when the cell of the second type network supporting the first type network registration is searched, the first type network registration is completed in the cell of the second type network supporting the first type network registration, so that when the cell of the second type network supporting the first type network registration is searched, the cell of the second type network can be preferentially utilized to complete the first type network registration, and the second type network registration can not be completed in the cell of the second type network not supporting the first type network registration directly, and the experience of a user can be improved.
Wherein fig. 2 is a flowchart illustrating a cell registration method according to an exemplary embodiment, and as shown in fig. 2, the method further includes:
Step S13, when the cell of the second type network supporting the first type network registration is not searched, the second type network registration is completed in the cell of the second type network not supporting the first type network registration.
Here, when a cell of the second type network supporting the registration of the first type network is not searched, the cell of the second type network carrying the registration identification supporting the first type network may be not searched in the second type network. For example, a cell carrying a 4G network supporting a 5G network registration identity is not searched. Here, the cell of the second type network that does not support the registration of the first type network may be a cell of the second type network that is not capable of providing the communication configuration information to the first type network. Here, when the cell of the second type network supporting the first type network registration is not searched, the second type network registration is completed in the cell of the second type network not supporting the first type network registration, so that the bad experience brought to the user due to the fact that the second type network registration cannot be performed after the first type network registration is unsuccessful can be reduced.
Wherein fig. 3 is a flowchart of a method for registering a cell according to an exemplary embodiment, as shown in fig. 3, after a cell of a second type network that does not support registration of a first type network completes registration of the second type network, the method further includes:
Step S14, after the registration time length of the second type network meets the first preset time length, full-band scanning of the cells of the second type network is carried out;
and when the cell supporting the second type network registered by the first type network is scanned, switching to the cell supporting the second type network registered by the first type network to finish the first type network registration.
Here, the first predetermined time period may be flexibly set according to the requirement, for example, set according to the moving speed of the mobile terminal, and when the moving speed of the mobile terminal is faster, a shorter first predetermined time period, for example, 3s, is set; when the moving speed of the mobile terminal is slow, a relatively long first predetermined period of time, such as 5s, is set. Here, the cells present around the mobile terminal are changed following the change of the location area of the mobile terminal. As the location area of the mobile terminal changes, different cells may appear around the mobile terminal. Some time after registering to the second type network, since the mobile terminal has small displacement, a new cell is unlikely to appear nearby, and the mobile terminal is unlikely to scan to the cell supporting the second type network registered by the first type network, so that scanning is not required. The full-band scanning of the cells of the second class network is carried out after the first preset time length, so that the power consumption of the mobile terminal caused by unnecessary scanning can be reduced, and the power is saved.
When the cells supporting the second type network registered by the first type network are scanned, the cells supporting the second type network registered by the first type network are switched to complete the first type network registration, so that the adaptability adjustment of the cell registration can be carried out according to the network environment, and the user experience is improved. For example, the first type of network is a 5G network, the second type of network is a 4G network, and the first type of network is switched from the 4G network to the 5G network, so that the 5G network can bring better experience to the user. For example, the mobile terminal sequentially passes through the area a and the area B, and when the area a does not search for the cell of the second type network supporting the registration of the first type network, the mobile terminal can only complete the registration of the second type network in the cell of the second type network not supporting the registration of the first type network. When the mobile terminal moves to the area B, the cells supporting the second type network registered by the first type network are scanned, and at the moment, the cells supporting the second type network registered by the first type network can be switched to complete the first type network registration in real time, so that better experience is brought to users.
Fig. 4 is a flowchart illustrating a method of cell registration, according to an exemplary embodiment, as shown in fig. 4, the method further comprising:
step S15: when the cells supporting the second type network registered by the first type network are not scanned, updating the first preset time length according to the first set time length to obtain a second preset time length, wherein the second preset time length is longer than the first preset time length; and after the registration time length of the second type network meets a first preset time length increased by a first set time length, carrying out full-band scanning of cells of the second type network.
Here, the first setting time period may be flexibly set according to an actual scene. For example, when the moving speed of the mobile terminal is relatively high (for example, when the moving speed is greater than the first setting threshold), a relatively short first setting period (for example, less than the second setting threshold) is set, for example, 0.5s; when the moving speed of the mobile terminal is slow (e.g., the moving speed is less than the third setting threshold), a first setting period of time, such as 1s, is set to be relatively long (e.g., greater than the fourth setting threshold).
Here, the cells present around the mobile terminal are changed following the change of the location area of the mobile terminal. As the location area of the mobile terminal changes, different cells may appear around the mobile terminal. And when the cells supporting the second type network registered by the first type network are not scanned, after the registration time length of the second type network meets the first preset time length increased by the first setting time length, carrying out full-band scanning of the cells of the second type network.
For example, if the initial value of the first predetermined duration is 5s and the first set duration is 6s, when the first scanning does not scan the cells of the second type network supporting the registration of the first type network, the mobile terminal will scan the full frequency band of the cells of the second type network again after the registration duration of the second type network satisfies the second duration 11s (5s+6s). Since the mobile terminal does not scan for the cells of the second type network supporting the registration of the first type network in the same place, the cells of the second type network supporting the registration of the first type network are not scanned even if frequently scanned. Here, the first predetermined duration can be adaptively adjusted according to the condition that the cell supporting the second type network registered by the first type network is not scanned, the cell is continuously increased, the electric energy waste caused by frequent searching of the mobile terminal is reduced, the electric energy consumption of the mobile terminal caused by unnecessary scanning can be reduced, and the electric energy is saved.
Wherein fig. 5 is a flowchart illustrating a cell registration method according to an exemplary embodiment, and as shown in fig. 5, the method further includes:
step S16, when scanning to support the second type network cell registered by the first type network, determining whether there is service data transmission or service data transmission requirement in the second preset time length;
when scanning to the cell supporting the second type network registered by the first type network, switching to the cell supporting the second type network registered by the first type network to complete the first type network registration comprises the following steps:
and when the cells of the second type network supporting the registration of the first type network are scanned and no service data transmission or service data transmission requirements exist in the second preset time, switching to the cells of the second type network supporting the registration of the first type network to finish the registration of the first type network.
Here, the second predetermined time period may be flexibly set according to the requirement, for example, flexibly set according to the importance level of the mobile terminal service, and when the importance level of the mobile terminal service is greater than the first set level threshold, a second predetermined time period greater than the first time threshold may be set. When the importance level of the mobile terminal service is less than the second set level threshold, a second predetermined period of time less than the second time threshold may be set. Here, the service may be a voice service, a video service, or the like. For example, in the voice service, the service importance level of the voice service is 3, and the first set level threshold is 2, and then the importance level of the voice service is greater than the first set level threshold, a duration greater than the first time threshold (for example, 5 s) may be set, for example, 6s. Here, when the cells supporting the second type network registered by the first type network are scanned, the switching is not performed immediately, but is performed when no service data transmission or no service data transmission requirement is determined in the second preset time, so that interruption of service data transmission or a terminal for requesting for data transmission can be reduced, user perception is not influenced, and better experience is brought to the user.
Wherein after the cell of the second type network supporting the first type network registration completes the first type network registration, the method further comprises:
step S17, the frequency point information of the cells supporting the second type network registered by the first type network is stored in a preset cell database.
Here, the frequency point information of the cell supporting the second type network registered by the first type network is stored in the preset cell database, so that the mobile terminal can quickly and reliably search the cell supporting the second type network registered by the first type network based on the frequency point information when the mobile terminal appears next time near the cell supporting the second type network registered by the first type network. And completing the first type network registration in the cell of the second type network supporting the first type network registration.
In step S12, a cell of a second type network supporting registration of the first type network is searched, including: when the received system message in the cell of the second type network includes the identification information supporting the first type network registration in the cell of the second type network, determining that the cell of the second type network supporting the first type network registration is searched.
Here, the mobile terminal may first receive the system message in the cell of the second type network where the mobile terminal is currently located, and then parse the system message after receiving the system message. When the analyzed system information comprises identification information supporting the first-type network registration in the cells of the second-type network, for example, when the 5G identification information is analyzed, the cells supporting the first-type network registration are determined to be searched.
In step S12, when a cell supporting a second type network registered by the first type network is searched, the registration of the first type network is completed in the cell of the second type network, including:
and when the cells supporting the second-class network registration are searched, completing the registration of the first-class network in the cells of the second-class network according to the priority of the cells of the second-class network.
The cells of the second type network can be divided into time division duplex cells and frequency division duplex cells according to different data transmission modes, and different experience can be brought by registering different cells.

In order to better understand the embodiments of the present invention, the following takes a mobile terminal as an example of a mobile phone, and the embodiments of the present disclosure are further described by 1 example:
example 1:
fig. 6 is a flowchart illustrating a cell registration method, as shown in fig. 6, for use in a mobile phone, according to an exemplary embodiment, comprising the steps of:
step S21, starting up the mobile phone;
step S22, searching whether a cell supporting a second type network registered by a first type network exists or not based on the frequency point information of the registered cell stored in a preset cell database; when a cell in which a second type network supporting registration of the first type network exists is searched, executing step S23; otherwise, executing step S24;
step S23, completing the first-class network registration in the cells of the second-class network supporting the first-class network registration; and performs step S28;
step S24, completing the registration of the second type network in the cells of the second type network which do not support the registration of the first type network;
step S25, after registering to the second type network T1, carrying out full-band scanning of the cells of the second type network, and confirming whether the cells of the second type network supporting the registration of the first type network are scanned; when a cell supporting a second type network registered by the first type network is scanned, step S26 is performed; otherwise, updating the T1 and executing step S25, after registering in the second-class network T1, performing full-band scanning of cells of the second-class network, and determining whether the cells of the second-class network supporting the registration of the first-class network are scanned. When a cell supporting a second type network registered by the first type network is scanned, step S26 is performed; when the cells supporting the second type network registered by the first type network are not scanned, updating the T1, and specifically adding a certain time length, such as 5s, on the basis of the original T1 to obtain updated T1;
Step S26, determining whether the cell of the second type network supporting the first type network registration has a service data transmission or a service data transmission requirement within T2 (where T2 may be set to t2=0.5S); when it is determined that there is no traffic data transmission or no traffic data transmission requirement within T2, step S27 is performed; otherwise, T1 is updated and returns to step S25.
