Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the description of the present application, it is noted that the terms "first", "second", "third", and the like are used merely for distinguishing between descriptions and are not intended to indicate or imply relative importance.

The cell access method provided in the embodiment of the present application may be applied to the environment as shown in fig. 2, where a terminal device 200 is in communication connection with a base station 100 through a wireless network; when the terminal device 200 enters an area covered by the cellular communication network, the terminal device 200 performs a cell search of a base station, and is generally able to search a plurality of base station cells and select a target base station cell from the plurality of base station cells for cell access. Here, each base station has a coverage area of a cell, and the base station 100 may be one or more of 5G, 4G, 3G, and 2G base stations.

The terminal device 200 specifically refers to a module capable of having a fifth-generation mobile network communication function or a device including the module, the terminal device may be a mobile terminal or an intelligent device, the mobile terminal may specifically be at least one of a mobile phone, a tablet computer, a notebook computer, and the like, and the intelligent device may include at least one of a portable wearable device, an intelligent household appliance, and an intelligent monitoring device, such as an intelligent watch, an intelligent refrigerator, a sweeping robot car recorder, a security camera device, and the like; the module may be any one of a 2G communication module, a 3G communication module, a 4G communication module, a 5G communication module, and an NB-IoT module.

In an embodiment, as shown in fig. 3, a cell access method is provided, which is described by taking the terminal device 200 in fig. 2 as an example, and includes the following steps:

s10: the terminal equipment searches for an SA cell, wherein the SA cell is a coverage area of a base station which adopts an independent networking mode for networking.

Specifically, when the terminal device enters a certain environment, cell search is performed, and specifically, an SA cell, an LTE cell, and the like may be searched. When cell search is performed, cell search can be performed according to frequency point information or a 5G frequency band preset by the terminal device.

S20: and determining the first priority of the searched SA cell according to the first preset information.

The first priority may represent the priority of the terminal device selecting SA cell access.

When a plurality of SA cells are searched, the searched SA cells are prioritized according to one or more network quality parameters of the SA cells. When the terminal device searches the SA cell while residing, the terminal device can acquire the network quality parameter of the searched cell. In some embodiments, the first preset information may include network quality parameters of the searched cells, such as one or more of signal strength, bandwidth, number of networks, time delay, signal-to-noise ratio, and the like.

S30: and selecting a target SA cell to try to access, wherein the target SA cell is the SA cell with the highest first priority.

The terminal device selects the SA cell with the highest first priority to attempt to register the 5G network.

Of course, the target SA cell may also be an SA cell with a first priority greater than the first priority threshold, and the first priority threshold may be preset according to requirements. It can be understood that if there are a plurality of SA cells whose first priority is greater than the preset first priority threshold, an SA cell is randomly selected for SA cell access; or if a plurality of SA cells meeting the first priority threshold exist, carrying out priority re-determination on the SA cells meeting the first priority threshold according to another network quality parameter, and selecting the SA cell with the highest priority to attempt access. When the terminal device only searches for one SA cell, the first priority of the SA cell is the highest, and the terminal device selects the SA cell to attempt cell access.

Specifically, after determining the target SA cell selected for access, the terminal device initiates a random access request to the base station corresponding to the target SA cell, and after receiving a response from the base station, the terminal device attempts to establish a connection with the base station corresponding to the target SA cell. After the terminal device accesses the target SA cell, the SA network, that is, the 5G network, is registered.

S40: and in response to the failure of selecting the target SA cell to attempt access, selecting a next SA cell and attempting access according to the first priority from high to low.

And after the selection of the target SA cell for trying to access fails, continuing to change the SA cell for trying to access. Specifically, SA cells with a priority less than that of the target SA cell may be selected to attempt access.

In the embodiment, the terminal device searches the SA cells and performs the first priority ranking on the searched SA cells to try to access the SA cells one by one according to the first priority from high to low, so that the terminal device can try to access the SA cells with a better network state. In addition, after the SA cell with the highest priority is selected to be failed to access, other SA cells are continuously tried to access, and the success rate of the terminal equipment to access the SA cell can be improved.

In an embodiment, when the terminal device searches for a plurality of SA cells and obtains network quality parameters of the SA cells, one or more of the network quality parameters may be selected according to the first preset information to perform the first priority determination. The first preset information may include at least one determination of signal strength, bandwidth, time delay, number of networking of the SA cell. Of course, the first preset information may also be determined according to other network quality parameters, such as signal-to-noise ratio, which is not listed here.

In one embodiment, the first preset information may include signal strength, that is, the first priority may be determined according to the signal strength of the SA cell.

Specifically, the SA cells are prioritized according to the signal strength in the network quality parameter, and the first priority is proportional to the signal strength, that is, the stronger the signal strength is, the higher the first priority is.

By determining the first priority according to the signal strength, the stability of the network signal of the terminal equipment can be ensured to a certain extent, the cell access failure caused by the instability of the network signal is reduced, and the success rate of the 5G cell access is further improved.

In one embodiment, the first preset information may include a bandwidth, i.e., the first priority may be determined according to the bandwidth of the SA cell.

Specifically, the plurality of SA cells are prioritized according to the bandwidth in the network quality parameter, and the first priority is proportional to the bandwidth, that is, the larger the bandwidth is, the higher the first priority is.

By determining the first priority according to the bandwidth, the situation that the signal strength is strong enough but information cannot be uploaded and downloaded can be avoided to a certain extent, namely the situation that the traffic is not taken away is often said, and then the terminal equipment can be enabled to access a network cell with a higher network speed to a certain extent.

In one embodiment, the first preset information may include a time delay, that is, the first priority may be determined according to the time delay of the SA cell.

Specifically, a plurality of SA cells are prioritized according to a delay in a network quality parameter, and the first priority is inversely proportional to the delay, that is, the smaller the delay, the higher the first priority.

By determining the first priority according to the time delay, the network time delay of the terminal equipment can be made lower to a certain extent.

In one embodiment, the first preset information may include a networking number, i.e., the first priority may be determined according to the networking number of the SA cell.

Specifically, the SA cells are prioritized according to the networking number in the network quality parameter, and the first priority is inversely proportional to the networking number, that is, the smaller the networking number is, the higher the first priority is.

According to the embodiment, the first preset information is set, and the first priority is determined according to the first preset information, so that the terminal equipment can be ensured to have high network quality when networking.

It will be appreciated that the various embodiments described above all determine the first priority in dependence upon a single network quality parameter, however, the first priority may be determined in dependence upon a plurality of network quality parameters, for example after a combined comparison in combination with signal strength and bandwidth.

In an embodiment, as shown in fig. 4, the first preset information includes a plurality of types of parameters, S20: determining a first priority of the searched SA cell according to the first preset information, wherein the first priority comprises the following steps:

s21: and determining a second priority of the SA cell according to the same parameter type.

The second priority is used for representing the sequence of the terminal equipment accessing the SA cell. The second priority may be determined according to a parameter other than the first preset information. For example, the first preset information includes signal strength, the second priority may be determined according to at least one of bandwidth, latency, and networking quantity.

Taking the second priority may be determined according to the time delay as an example, after the terminal device searches for at least 2 SA cells, the second priority of the SA cells is determined according to the size of the time delay, for example, when the time delay of the first SA cell searched by the terminal device is 460 milliseconds, and the time delay of the second SA cell is 400 milliseconds, the second priority of the second SA cell is greater than the second priority of the first SA cell.

S22: and determining at least two SA cells with the difference value of the same type of parameters smaller than a preset threshold, and determining the first priority of the at least two SA cells according to the sequence of the second priority from high to low, wherein the second priority and the first priority are in a direct proportion relation.

The difference value of the parameters of the same type is smaller than the preset threshold value, which indicates that the parameter values corresponding to the first preset information between the SA cells are equal or have a small difference, so that the access sequence of the terminal device can be determined by determining the second priority of the SA cells, and the higher the second priority is, the higher the first priority is. That is, for the first priority and the second priority, the terminal device prefers the SA cell with the second priority to access, and the priority degree of the second priority is greater than the first priority.

Taking the first preset information including signal strength and time delay as an example, the terminal device searches for 3 SA cells, which are respectively a first SA cell, a second SA cell and a third SA cell, wherein a difference between the signal strengths of the first SA cell and the second SA cell is smaller than a preset threshold, the signal strength of the third SA cell is smaller than the first SA cell and the second SA cell, and the time delay of the first SA cell is 460 milliseconds, and the time delay of the second SA cell is 400 milliseconds, then it is determined that the second priority of the second SA cell is greater than the second priority of the first SA cell, and the priority of the third SA cell is smaller than the first SA cell and the second SA cell, and then according to the second priority, it is finally determined that the first priorities of the 3 SA cells are from high to low: a second SA cell, a first SA cell and a third SA cell.

The embodiment can avoid the problem that the first priority cannot be determined when the parameter values corresponding to the first preset information between the SA cells are equal. In addition, when the parameter values corresponding to the first preset information between the SA cells are not greatly different, the networking sequence of the terminal equipment is determined by determining the second priority, so that the terminal equipment has a higher network speed after networking.

Of course, the 5G cell access sequence of the terminal device may also be determined comprehensively by combining the signal strength and the time delay, or may also be determined after comprehensively comparing the signal strength, the bandwidth, the networking number and the time delay, which is not described herein again.

Referring to fig. 5, in an embodiment, S30: in response to failure of selecting the target SA cell to attempt access, selecting a next SA cell and attempting access in order of a first priority from high to low, comprising the steps of:

s31: in response to a failure to select the target SA cell to attempt access, the first priority of the target SA cell is decreased.

S32: and selecting the next SA cell to attempt access according to the adjusted first priority from high to low.

In this embodiment, the priority of the selected SA cell is lowered, so that the first priority of other SA cells is raised, thereby reselecting the SA cell for 5G cell access.

It should be noted that, the first priority of the target SA cell may be set to be the lowest priority of the target SA cell, or may be set to be several lower priorities, which is not specifically limited herein.

In this embodiment, the priority of the target SA cell is reduced to re-determine the order in which the terminal accesses the SA cell, so that the first priorities of the remaining SA cells are increased, and further, the terminal device reselects the SA cell to attempt access, thereby reducing the SA cells with poor access network status, and increasing the success rate of the terminal registering in the 5G network.

In an embodiment, as shown in fig. 6, after all the SA cells searched for by the terminal device fail to be accessed, the cell access method further includes:

s61: and searching the LTE cell in response to the failure of accessing all the searched SA cells.

S62: and selecting the LTE cell access from the searched LTE cells.

The LTE cell is a Long Term Evolution (LTE) cell.

In the embodiment, after the terminal equipment fails to select the SA cell for random access, the LTE cell is searched and accessed, and the terminal equipment can register other networks by accessing the LTE cell, so that the network disconnection time of the terminal is shortened, and the user experience is improved.

In an embodiment, the cell access method may further include: and after the terminal equipment fails to access all the searched SA cells, the terminal equipment searches the LTE cell according to the NSA frequency point according to the preset NSA frequency point.

After searching a plurality of LTE cells according to the preset NSA frequency point, the terminal equipment can determine the third priority between at least two LTE cells according to the second preset information, then selects to access the LTE cells one by one according to the third priority from high to low, and accesses the NSA network through the selected LTE cells.

Specifically, the LTE cell with the highest third priority may be selected first to attempt to access the 5G network, and certainly, the LTE cell with the third priority greater than the third priority threshold may also be selected to attempt to access the 5G network, and the second priority threshold may be preset according to requirements.

After the LTE cell selected for access is determined, the terminal equipment initiates a random access request to the base station corresponding to the LTE cell selected for access, after the terminal equipment receives the response of the base station, the terminal equipment establishes connection with the base station corresponding to the LTE cell selected for access, then the terminal equipment receives 5G measurement information issued by the base station and executes corresponding step operation, so that the terminal equipment performs random access on the 5G side, and accesses to the NSA network.

The second preset information may include network quality parameters of the searched cell, such as one or more of signal strength, bandwidth, number of networks, time delay, signal to noise ratio, and the like.

In an embodiment, the second preset information may include signal strength, that is, the third priority may be determined according to the signal strength of the LTE cell, and the signal strength of the LTE cell with the second priority is proportional, that is, the stronger the signal strength is, the higher the third priority is.

In an embodiment, the second preset information may include signal strength, that is, the third priority may be determined according to a bandwidth of an LTE cell configured with a 5G frequency point, and the second priority is directly proportional to the bandwidth of the LTE cell configured with the 5G frequency point, that is, the larger the bandwidth is, the higher the second priority is.

In an embodiment, the second preset information may include signal strength, that is, the third priority may be determined according to a bandwidth of the LTE cell, and the third priority is inversely proportional to a delay of the LTE cell, that is, the smaller the delay, the higher the third priority is.

In an embodiment, the second preset information may include signal strength, that is, the third priority may be determined according to the number of networking configured with the LTE cell, and the third priority is inversely proportional to the number of networking configured with the LTE cell, that is, the smaller the number of networking, the higher the third priority is.

And if the terminal equipment does not search the LTE cell with the preset NSA frequency point, the terminal equipment searches the LTE cell without the preset NSA frequency point.

In the embodiment, the LTE cell with the preset NSA frequency point is searched first, and when the LTE cell with the preset NSA frequency point cannot be searched, the LTE cell without the preset NSA frequency point is accessed, so that the terminal can be accessed to the LTE cells with different types, and the time for network disconnection of the terminal is reduced.

Certainly, when the terminal device cannot access the cell and register the network through the cell access method, the terminal device may continue to search for the 3G cell and the 2G cell and try to access such cell for network registration.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
