Detailed Description
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.
The terminal can perform network search in various scenes such as terminal startup, network interruption, or network search manually set by a user. When a terminal searches a network, frequency sweeping is generally performed in each network system according to priority, information of all frequency points existing in the current environment is acquired, and then system messages of cells corresponding to the frequency points are acquired according to a certain sequence to determine a PLMN corresponding to the cell, so that the network can be further selected.
For example, in a manual network searching process, the terminal needs to sequentially acquire system messages of cells corresponding to all frequency points in a frequency sweeping result, so as to determine a PLMN of each network type in the current environment, and then display the acquired PLMN result of each network type to a user.
For another example, for the manual network selection or automatic network selection process, the terminal receives the system message of the cell corresponding to the frequency point from the first frequency point in the frequency sweeping result, determines the PLMN corresponding to the frequency point and whether the residence condition of the target PLMN for network selection is met according to the system message, if the residence condition is not met, the terminal receives the system message of the cell corresponding to the next frequency point, and performs the steps in sequence until the cell meeting the residence condition is found or all frequency point cells try to receive the system message.
It can be seen that, in the process of network searching or network selection, for each frequency point, the terminal needs to receive the system message of the corresponding cell to determine the PLMN corresponding to the cell, which is time consuming and power consumption of the terminal is high.
Therefore, the application provides a network searching method, aiming at the process of searching or selecting the network, a filtering list of the frequency points is respectively constructed, and the filtering list comprises the frequency points and the corresponding PLMN and network system, so that when the terminal searches or selects the network, the PLMN and the network system of the frequency points in the filtering list can be directly determined, the system information of the cell corresponding to the frequency points does not need to be obtained any more, the network searching time is shortened, and the power consumption of the terminal is reduced.
A terminal as referred to in this application may refer to a device that provides voice and/or data connectivity to a user, a handheld device having wireless connection capability, or other processing device connected to a wireless modem. The terminal may communicate with at least one core Network via a Radio Access Network (RAN for short). The terminals may be mobile terminals such as mobile telephones (or so-called "cellular" telephones) and computers with mobile terminals, e.g. portable, pocket, hand-held, computer-included or car-mounted mobile devices, which exchange voice and/or data with a radio access network.
The Terminal may also be referred to as a Terminal device (Terminal Equipment), a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a Mobile Station (Mobile Station), a Remote Station (Remote Station), an Access Point (Access Point), a Remote Terminal (Remote Terminal), an Access Terminal (Access Terminal), a User Terminal (User Terminal), a User Agent (User Agent), or a User device (User Equipment), which is not limited herein.
Fig. 1 is a schematic flowchart of a network searching method according to an embodiment of the present application. The network searching method can be applied to the manual network searching process. As shown in fig. 1, the method includes:
s101, obtaining a frequency sweeping result, wherein the frequency sweeping result comprises at least one frequency point.
And the terminal acquires the information of the frequency points existing in the current environment through frequency sweeping. Optionally, the terminal may perform frequency sweeping on the network standard with the highest priority to obtain the corresponding frequency point according to the preset network standard priority, perform subsequent processing from S102 to S107 on the frequency point of the network standard with the highest priority, then continue to perform frequency sweeping on the next network standard to obtain the corresponding frequency point for processing, and so on until the processing of all the frequency points is completed.
S102, judging whether the frequency point is in a network searching filtering list or not aiming at each frequency point; if the frequency point is in the network searching filtering list, executing S103; if the frequency point is not in the network searching filtering list, S106 is executed.
The network searching and filtering list comprises corresponding relations among frequency points, PLMN and network systems.
The manual network searching process is triggered by setting on the terminal by the user, for example, as shown in fig. 2, after the user closes the automatically selected option in the available network setting, the manual network searching is triggered, and the terminal can perform frequency point processing according to the network searching filtering list.
After the terminal obtains the frequency sweeping result, each frequency point can be sequentially processed according to a preset sequence rule, for example, the sequence of the frequency point signal intensity from high to low. Therefore, all frequency points under each network system are processed according to the sequence of the network system priority from high to low and the frequency point signal intensity from high to low.
Firstly, whether the frequency point is in a network searching filtering list is judged, and because the corresponding relation among the frequency point, the PLMN and the network system is stored in the network searching filtering list, if the frequency point is in the network searching filtering list, the terminal can directly acquire the PLMN corresponding to the frequency point according to the network searching filtering list without acquiring through system information. And if the frequency point is not in the network searching filtering list, the terminal needs to acquire the PLMN corresponding to the frequency point through the system message.
S103, judging whether the PLMN and the network type corresponding to the frequency point are in the network searching result; if the PLMN and the network type corresponding to the frequency point are not in the network searching result, S104 is executed; and if the PLMN and the network system corresponding to the frequency point are in the network searching result, S102 is executed again to judge whether the next frequency point is in the network searching filtering list or not until the judgment of all frequency points in the frequency sweeping result is finally completed.
If the frequency point is in the network searching filter list, the terminal acquires the PLMN and the network system corresponding to the frequency point according to the network searching filter list, therefore, the terminal only needs to determine whether the PLMN and the network system corresponding to the frequency point are already in the network searching result, if the PLMN and the network system corresponding to the frequency point are already in the network searching result, the terminal can directly skip the frequency point and continue to process the next frequency point, namely S102 is executed again to judge whether the next frequency point is in the network searching filter list, and the steps after execution are circulated until the judgment of all the frequency points in the frequency sweeping result is finally completed. And if the PLMN and the network type corresponding to the frequency point are not in the network searching result, continuing to execute S104.
S104, judging whether the signal intensity of the frequency point reaches a preset threshold or not; if the signal intensity of the frequency point reaches the preset threshold, executing S105; and if the signal intensity of the frequency point does not reach the preset threshold, executing S106.
And S105, adding the PLMN and the network type corresponding to the frequency point into the network searching result.
When the frequency point is in the network searching filtering list and the PLMN and the network standard corresponding to the frequency point are not in the network searching result, the terminal needs to determine whether the PLMN and the network standard corresponding to the frequency point need to be added to the network searching result according to the signal intensity of the frequency point, and if the signal intensity of the frequency point reaches a preset threshold, S105 can be executed to directly add the PLMN and the network standard corresponding to the frequency point to the network searching result; if the signal intensity of the frequency point does not reach the preset threshold, the system information of the cell corresponding to the frequency point is needed to judge. For example, the network searching result displayed on the terminal user interface is shown in fig. 3.
S106, starting the system message of the cell corresponding to the receiving frequency point, and judging whether the system message is received; if the system message is received, executing S107; if the system message is not received, S102 is executed again to determine whether the next frequency point is in the network searching filtering list, and the steps after execution are cycled until the determination of all frequency points in the frequency sweeping result is finally completed.
S107, adding at least one PLMN and a network type corresponding to the frequency point into the network searching result, receiving the adjacent cell configuration message of the frequency point, and adding at least one PLMN and a network type corresponding to the adjacent cell frequency point and the frequency point in the adjacent cell configuration message into a network searching filtering list.
When the frequency point is not in the network searching and filtering list, or the frequency point is in the network searching and filtering list but the PLMN and the network type corresponding to the frequency point are not in the network searching result and the signal intensity of the frequency point does not reach a preset threshold, the terminal needs to determine the network searching result by receiving the system message of the cell corresponding to the frequency point, and if the terminal normally receives the system message, the PLMN and the network type corresponding to the frequency point are added into the network searching result according to the system message. And if the terminal determines that the PLMN corresponding to the frequency point is one according to the system message, adding one PLMN and the network system corresponding to the frequency point into the network searching result, and if the terminal determines that the PLMN corresponding to the frequency point is multiple according to the system message, adding the PLMNs and the network systems corresponding to the frequency point into the network searching result. If the system message is not received, S102 is executed again to continuously determine whether the next frequency point is in the network searching filtering list, and the steps after execution are cycled until the determination of all frequency points in the frequency sweeping result is finally completed.
In addition, in an actual network environment, a terminal is under multi-cell coverage in many scenarios. For example, in a certain location, there are network coverage of the operator 1, the operator 2, and the operator 3 at the same time, and this scenario also often has multi-cell coverage under the same operator, for example, there are multiple 4G cells, multiple 2G cells, multiple 4G cells of the operator 2, and multiple 4G cells of the operator 3 at the same time. If the same operator has coverage of multiple cells, the coverage is generally embodied in the neighboring cell configuration of the cell.
Therefore, in the method of this embodiment, in order to further improve the network searching efficiency and reduce power consumption, after receiving the system message and adding the at least one PLMN and network type corresponding to the frequency point to the network searching result, the terminal also receives the neighbor cell configuration message of the frequency point, and adds the neighbor cell frequency point in the neighbor cell configuration message and the at least one PLMN and network type corresponding to the frequency point to the network searching filter list.
Illustratively, after a 4G cell of an operator 2 is searched through a current frequency point, 4G and 3G neighbor frequency points of the cell are acquired through neighbor configuration information, and the neighbor frequency points and a PLMN and a network standard corresponding to the current frequency points are added into a network searching filter list, so that in the subsequent frequency point searching process, the system information receiving process of a plurality of 4G frequency points and 3G frequency points of the operator 2 can be reduced according to the network searching filter list, the network searching efficiency is effectively improved while the reliable network searching result is ensured, and the power consumption is reduced.
According to the network searching method provided by the embodiment, the PLMN corresponding to the frequency point can be directly obtained according to the network searching filter list collected in the network searching process or before, so that the system message receiving process of part of the frequency points is skipped, the network searching efficiency is improved, and the power consumption of the terminal is reduced.
Fig. 4 is a schematic flowchart of a network searching method according to an embodiment of the present application. The network searching method can be applied to the manual/automatic network selection process. As shown in fig. 4, the method includes:
s401, obtaining a frequency sweeping result, wherein the frequency sweeping result comprises at least one frequency point.
And the terminal acquires the information of the frequency points existing in the current environment through frequency sweeping. Optionally, the terminal may perform frequency sweeping on the network standard with the highest priority to obtain a corresponding frequency point according to a preset network standard priority, perform subsequent processing from S402 to S405 on the frequency point of the network standard with the highest priority, then continue to perform frequency sweeping on the next network standard to obtain a corresponding frequency point, and so on until it is determined that the cell meeting the residence condition resides, or complete processing on the frequency points in all network standards under the condition that the cell meeting the residence condition is not determined.
S402, starting from a first frequency point, judging whether the frequency point is in a network selection filtering list or not; if the frequency point is in the network selection filtering list, S402 is continuously executed to determine whether the next frequency point is in the network selection filtering list, until it is determined that the first frequency point is not in the network selection filtering list, S403 is executed.
And the network selection filtering list comprises the frequency points which do not meet the residence conditions, and the corresponding PLMN and network systems.
After the terminal obtains the frequency sweeping result, each frequency point can be sequentially processed according to a preset sequence rule, for example, the sequence of the frequency point signal intensity from high to low. Therefore, all frequency points under each network system are processed according to the sequence of the network system priority from high to low and the frequency point signal intensity from high to low.
Firstly, judging whether the frequency point is in a network selection filtering list, wherein the network selection filtering list stores the corresponding relation among the frequency point which does not meet the residence condition, the PLMN and the network system, therefore, if the frequency point is in the network selection filtering list, the terminal can directly determine that the frequency point does not meet the residence condition without system information, so as to skip the frequency point, continue to judge the next frequency point, and the terminal needs to further execute S403 to judge whether the PLMN corresponding to the first frequency point meets the residence condition until the terminal determines that the first frequency point is not in the network selection filtering list.
S403, determining whether the PLMN corresponding to the first frequency point meets a residence condition; if the PLMN corresponding to the first frequency point meets the camping condition, performing S404; if the PLMN corresponding to the first frequency point does not satisfy the camping condition, S405 is performed.
And S404, residing in the cell corresponding to the first frequency point.
S405, receiving a neighbor cell configuration message of a cell corresponding to the first frequency point, adding the frequency point in the neighbor cell configuration message and a PLMN and a network type corresponding to the first frequency point into a network selection filtering list, and continuing to execute S402 to judge whether a next frequency point of the first frequency point is in the network selection filtering list.
For a first frequency point which is not in the network selection filtering list, the terminal can start to receive the system information of a cell corresponding to the first frequency point; and determining whether the PLMN corresponding to the first frequency point meets the residence condition or not according to the system message. And if the PLMN corresponding to the first frequency point meets the residence condition, the terminal resides in the cell corresponding to the first frequency point, and the network selection process is finished. If the PLMN corresponding to the first frequency point does not satisfy the residence condition, for example, if it is determined that the PLMN corresponding to the first frequency point is a Forbidden PLMN (FPLMN) through the system message during automatic network selection, or it is determined that the PLMN corresponding to the first frequency point is a non-manual network selection specified PLMN through the system message during manual network selection, it may be determined that the PLMN corresponding to the first frequency point does not satisfy the residence condition, S402 is executed to continue to determine whether a next frequency point of the first frequency point is in the network selection filter list, and the subsequent steps are executed to cycle until it is determined that the cell satisfying the residence condition resides, or the processing of the frequency points under all network systems is completed under the condition that the cell satisfying the residence condition is not determined.
In addition, in order to further improve the network selection efficiency and reduce power consumption, the terminal further receives a neighboring cell configuration message of the first frequency point under the condition that the PLMN corresponding to the first frequency point does not meet the residence condition, and adds the neighboring cell frequency point in the neighboring cell configuration message and the PLMN and network system corresponding to the first frequency point to the network selection filter list.
Illustratively, when a target network of a network selection is a PLMN of an operator 1, determining that a PLMN of an operator 2 corresponding to a first frequency point is a FPLMN according to a system message of a cell corresponding to the first frequency point, acquiring neighboring frequency points of 4G and 3G of the cell through a neighboring configuration message, and adding the neighboring frequency points and the PLMN and network format corresponding to the first frequency point into a network selection filtering list, so that in a subsequent frequency point searching process, the neighboring frequency points can be directly skipped according to the network selection filtering list, a system message receiving process of the neighboring frequency points is reduced, a reliable network selection result is ensured, network searching efficiency is effectively improved, and power consumption is reduced.
The network searching method provided by the embodiment can directly skip frequency points which do not meet the network selection residence condition under each system according to the network selection filtering list collected in the network selection process or before during network selection, thereby reducing the system message receiving process, improving the network selection efficiency and reducing the terminal power consumption.
