Detailed Description
The core of the application is to provide a wireless communication module network selection method, a wireless communication module network selection device, a computing device and a computer readable storage medium, so as to improve the efficiency of network selection of the wireless communication module.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, 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 embodiments of the present application, but not all embodiments. 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 related art, the network selection method described in 3GPP is generally adopted to perform network selection in such a complex network environment. However, network selection completely according to the network selection method described in 3GPP may result in slow network selection and high power consumption, and the selected cell may not meet the service requirement of the wireless communication module.
Therefore, the application provides a wireless communication module network selection method, which judges whether the configuration information of a target cell is GSM only when 2G network selection is performed, adds the cell with the GSM only into a blacklist, prohibits the cell from residing, eliminates the cell incapable of performing data service, improves the efficiency of 2G network selection, and reduces power consumption. And, connection to a cell that cannot satisfy the wireless communication module is avoided.
A wireless communication module network selection method provided by the present application is described below by an embodiment.
Referring to fig. 1, fig. 1 is a flowchart illustrating a network selection method of a wireless communication module according to an embodiment of the present disclosure.
In this embodiment, the method may include:
s101, performing 2G network selection to obtain a target cell;
therefore, in the alternative, 2G (second generation mobile phone communication technical specification) network selection is performed to obtain the target cell. The 2G network selection mainly refers to network selection under the 2G condition, and a corresponding target cell is selected. In the prior art, generally, the target cell is directly camped, and then data service is performed. However, in practical situations, after the corresponding target cell can be connected, there is no way to perform data service due to the complexity of the network. Therefore, in the prior art, after the network is connected, it is found that the data service cannot be performed, so that network selection is performed again, and the efficiency of data transmission is reduced.
S102, judging whether the configuration information of the target cell is GSM only;
on the basis of S101, this step is intended to determine whether the configuration information of the target cell is GSM only (a configuration option). On the basis that the previous step confirms the target cell, the step judges whether the configuration information of the target cell is GSM only, but not directly residing in the target cell. If the configuration information of the target cell is GSM only, it indicates that the target cell has no way to perform data service, and the target cell needs to be excluded.
If the application scene only has data service, an AT command can be added to set whether the application scene is the data service scene, or the current version is set only for the data service scene when the version is compiled, and judgment conditions are added when 2G network selection is performed. The step of adding this determination to the prior art is achieved. That is, in this embodiment, the step of determining whether the configuration information of the target cell is GSM only may be set based on the AT command. The step of judging whether the configuration information of the target cell is the GSM only may also be set when compiling the version.
Further, if the cell is a GSM only cell, the cell is not camped, and the current cell is added to the blacklist, the forbidden duration of the GSM only cell added to the blacklist is set to 6 hours, and the cell in the blacklist is not allowed to be reselected in the forbidden duration, so that during the 2G data service, the cell cannot be reselected due to good GSM only cell signals, and the service stability when the wireless communication module is used for the data service is ensured.
S103, if the configuration information is GSM only, adding the target cell into a blacklist, and executing the step of 2G network selection;
on the basis of S102, when the configuration information is GSM only, the target cell is added to the blacklist, and the step of performing 2G network selection is performed. That is, the target cell is added to the blacklist, and connection with the target cell is avoided, instead of connection which is caused by finding no way to transmit data after connection.
The time length of a timer of a blacklist mechanism can be 6 hours, after a GSM only cell timer in the blacklist is overtime, the GSM only cell timer is deleted from the blacklist, and then the GSM only cell can be selected, so that an operator is prevented from changing the configuration of the cell, and the cell cannot be selected when a signal is better; the upper limit of the number of the GSM only cells stored in the blacklist is 20, after the storage is full, the GSM only cells stored in the blacklist are deleted, then the GSM only cells in the preceding and following blacklists move forward, and the new GSM only cell is stored to the last bit.
Further, the step of "adding the target cell to the blacklist" in this step may include:
and adding the target cell into a blacklist, and setting a timer for the target cell based on a preset time length.
It can be seen that, in this alternative, it is mainly the corresponding timer that is set for the target cell. The duration of the timer may be set based on experience, or based on a refresh period of the base station, or based on a complex environment of a network.
Correspondingly, if the timer is overtime, the method further comprises the following steps:
the target cell is removed from the blacklist.
It can be seen that, in this alternative, when the timer expires, which indicates that the recording duration of the target cell in the blacklist is longer, and the configuration of the target cell may be changed, the target cell may be deleted from the blacklist, and the number of selectable cells may be increased.
Further, the step of operating the blacklist in this step may further include:
step 1, setting the upper limit of the cell number for a blacklist;
and 2, deleting the cell recorded earliest in the blacklist when the number of the cells of the blacklist is greater than the upper limit of the number of the cells.
It can be seen that the present alternative scheme mainly illustrates how the blacklist is updated based on the number. In the alternative, the upper limit of the number of cells is set for the blacklist, and when the number of the cells of the blacklist is greater than the upper limit of the number of the cells, the cells recorded earliest in the blacklist are deleted.
S104, if the configuration information is not GSM only, whether the target cell meets the residence condition is judged;
on the basis of S102, when the configuration information is not GSM only, it is determined whether the target cell satisfies the camping condition. That is, the target cell has a condition for performing a data service, and on this basis, it is determined whether the target cell satisfies a camping condition. The camping condition mainly means that the device can camp on the cell.
And S105, if the target cell meets the residence condition, the target cell is resided.
On the basis of S104, the present step aims to camp on the target cell if the target cell satisfies the camping condition.
In summary, in this embodiment, when selecting a network through 2G, it is determined whether the configuration information of the target cell is GSM only, and the cell in which the GSM only exists is added to the blacklist, and the cell is prohibited from being camped, so that a cell that cannot perform a data service is excluded, the efficiency of 2G network selection is improved, and power consumption is reduced. And, connection to a cell that cannot satisfy the wireless communication module is avoided.
In the following, a process of LTE (Long Term Evolution of universal mobile telecommunications technology) network selection in a network selection method of a wireless communication module according to the present application is described with reference to another specific embodiment.
Referring to fig. 2, fig. 2 is a flowchart of an LTE network selection process of a network selection method for a wireless communication module according to an embodiment of the present disclosure.
In this embodiment, the method may include:
s201, acquiring a base station BA table sent by a base station;
as can be seen, this step aims to obtain the base station BA table sent by the base station.
And the base station BA table is a BA table obtained by collecting and recording the base station. Moreover, when the wireless communication module of this embodiment is within the range of the base station, the base station sends the BA list to the wireless communication module.
For example, the bs sends the BA list through RRCConnectionReconfiguration message. When the wireless communication module receives the MeasConfig information unit in the RRCConnectionReconfiguration message and measures a cell with good quality, the wireless communication module stores the relevant frequency point information into a BA table configured by the base station, and the frequency point information is used for starting up and searching the network.
S202, judging whether a target frequency point meeting the access condition exists or not based on a base station BA table and an experience BA table;
on the basis of S201, this step is intended to determine whether there is a target frequency point that meets the access condition based on the base station BA table and the experience BA table. That is, whether a suitable target frequency point exists is judged based on the dual BA table. The access condition may be any one of conditions provided in the prior art.
S203, when the target frequency point does not exist, executing full-frequency network searching operation;
on the basis of S202, this step aims to perform a full-frequency network searching operation when there is no target frequency point. That is, on the basis of searching the dual BA table, when there is no way to search the target frequency point, the full-frequency network searching operation is performed. The full-frequency network searching operation can adopt any one of the full-frequency network searching operations provided by the prior art, and is not specifically limited herein.
S204, when the target frequency point exists, judging whether the target frequency point meets the residence condition;
on the basis of S202, this step aims to determine whether the target frequency point meets the residence condition when the target frequency point exists. That is, when the target frequency point satisfies the condition, the determination of the staying condition is performed.
And S205, if the target frequency point meets the residence condition, the target frequency point is resided, and a residence success message is sent.
On the basis of the step S204, the step aims to reside the target frequency point and send a residing success message if the target frequency point meets the residing condition.
In the prior art, in the existing startup network selection scheme, historical frequency points are searched by only using an empirical BA table (a BA table of a network acquired through system information), regardless of the BA table configured by a base station, as 5G business starts, 2G/3G network quits, three operators in China can replan frequency spectrum, if the replanted frequency spectrum is searched by only using the historical frequency points, the BA table configured by the base station is not added, if the historical frequency points do not contain the BA table configured by the base station during network searching, after the network searching of the historical frequency points fails, the network can be searched to available frequency points only when the network searching is waited, the startup network searching time is increased, and the product lacks competitiveness. Therefore, in this embodiment, in order to increase the number of search frequency points, in this embodiment, a base station BA table and an experience BA table are used to perform frequency point search.
The steps in this embodiment may include:
step 1, when starting up and searching a network, searching an experience list BA and a BA list configured by a base station, and if residing is successful, reporting a system message;
step 2, if the experience list BA and the BA list configured by the base station do not find the suitable cell, starting full-frequency search, successfully searching, meeting the resident condition and reporting the system information;
step 3, if the search is failed, judging whether other networks can reside, if other PLMNs (Public Land Mobile networks) can reside, the limited residence is carried out, and starting a limited timer;
and 4, if the search is failed, no PLMN can reside, reporting no network, and starting a no network timer.
Further, the full-frequency network searching operation in this step may include:
step 1, when no target frequency point exists, executing full-frequency network searching operation;
step 2, if the full-frequency network searching operation is successfully executed, residing the searched frequency points and sending a residing success message;
step 3, if the execution of the full-frequency network searching operation fails, judging whether other resident communication networks exist or not;
step 4, if the communication network capable of residing exists, residing the communication network based on the limited timer;
and 5, if the communication network which can be resided does not exist, sending a wireless message, and executing network searching operation based on the wireless timer.
It can be seen that the present alternative mainly explains how to perform full-frequency network searching. In the alternative scheme, when the target frequency point does not exist, the full-frequency network searching operation is executed, if the full-frequency network searching operation is successfully executed, the searched frequency point is resident, a resident success message is sent, if the full-frequency network searching operation is failed to be executed, whether other resident communication networks exist or not is judged, if the resident communication networks exist, the communication networks are resident based on the limited timer, if the resident communication networks do not exist, the network-free message is sent, and the network searching operation is executed based on the network-free timer.
Further, the camping on the communication network based on the limited timer in the last alternative may include:
step 1, executing residence to a communication network, and recording the execution times of limited residence;
step 2, if the execution times is between the first limited residence time and the second limited residence time, setting a limited timer as a first limited duration;
step 3, if the execution times is greater than the second limited residence times, setting the limited timer to be a second limited duration; wherein the second limited duration is greater than the first limited duration;
and 4, circularly executing network searching operation based on the limited timer.
It can be seen that the present alternative mainly illustrates how to perform the parking, and the parking performed in the present embodiment is limited parking.
Specifically, for example, the limited timer duration and interval may be set as follows:
when the limited residence time is from 1 st time to 5 th time, the limited timer has the time length of 12s, and the network searching is restarted after the timer is overtime;
after the 5 th time, the limited timer is 1 hour long, and the network is searched again after the timer is overtime;
if the UE (User Equipment) moves (cell change) within the 1 hour timer period, a network search is immediately started, and then the loop is performed in a 12s/1 hour manner 5 times.
Further, in the last alternative, the performing the network searching operation based on the wireless timer may include:
step 1, recording and judging the number of times of no network of a communication network which can reside;
step 2, setting a continuously increased timing duration for the wireless timer according to the increment of the wireless times;
and 3, circularly executing network searching operation based on the wireless timer.
It can be seen that the present alternative scheme mainly explains how to perform the netless network searching operation.
Specifically, for example, the duration and interval of the wireless timer may be set as follows:
when no network exists for the 1 st time, the network is searched again after 10 s;
starting a no-network timer from 2 nd to 9 th no-network, wherein the time length is 20s, and the timer begins to find a network again after being overtime;
starting a no-network timer when no network exists from the 10 th time to the 18 th time, wherein the time is 40s, and the network searching is started again after the timer is overtime;
starting a no-network timer when the network is unavailable for the 19 th time, wherein the time is 60s, and the network is searched again after the timer is overtime;
and resetting the timer times once the network searching is successful.
In the prior art, because network searching and power consumption of limited and no network are in inverse proportion, the shorter the network searching interval is, the shorter the time for searching a proper cell is, the higher the power consumption is, the longer the network searching interval is, the longer the time for searching a proper cell is, and the lower the power consumption is. Therefore, in order to meet the requirements of quickly searching a suitable cell and enabling power consumption to be possible, the setting method can be used for power consumption and network duration recovery, the current network finding strategy is the most reasonable network finding strategy, power consumption is reduced, and network duration is prolonged.
