Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The network selection method provided by the invention can be applied to the application environment shown in figure 1. The network selection method is applied to a mobile communication system. The mobile communication system includes a mobile terminal 101 and a base station 102. Wherein mobile terminal 101 communicates with base station 102 via a network. The base station 102 serves as a network service side to provide network services for the mobile terminal 101, and the mobile terminal 101 serves as a user side to interact with a user.
The network selection method provided by the embodiment of the invention mainly focuses on the interaction between the mobile terminal 101 and the user, can be applied to the mobile terminal 101, and can prompt the user to switch the manual network selection mode when entering a roaming area by adding the reminding function when the mobile terminal 101 selects the network, thereby reducing the energy consumption of the mobile terminal 101 when the mobile terminal 101 roams in the roaming area. In embodiments, the mobile terminal 101 may include, but is not limited to, various smartphones, tablets, portable wearable devices, and the like. The mobile terminal 101 is configured with a Subscriber Identity Module (SIM) card, for example, a Subscriber Identity Module (SIM) card of a mobile phone, and the mobile phone can only enable the mobile network service by being configured with the SIM card. The subscriber identity module signs a network service agreement with the local operator, i.e. the local home network configured by the subscriber identity module, the mobile terminal 101 uses the local home network locally, and uses the mobile network service away from the local area belongs to the roaming service, i.e. uses the roaming network at the roaming place.
The network selection mode of the mobile terminal 101 includes an automatic network selection mode and a manual network selection mode. And when the manual network selection mode is not started, the mobile terminal operates in the automatic network selection mode. In the automatic network selection mode, the mobile terminal automatically sends a network service request to a network service side, such as a base station, where the mobile terminal is currently located, and automatically selects a PLMN with the highest priority in an available network list to access so as to obtain roaming service, thereby meeting the communication requirements of users.
A network selection method according to an embodiment of the first aspect of the present invention is described below with reference to fig. 2 and fig. 3, and in the embodiment, the network selection method is mainly applied to the mobile terminal 101 in fig. 1 for example.
Fig. 2 is a flowchart of a network selection method according to an embodiment of the present invention, and as shown in fig. 2, the network selection method according to the embodiment of the present invention at least includes steps S1-S3, which are described as follows.
Step S1, automatically searching for the currently available operator network.
The currently available operator network is an available operator network where the mobile terminal is currently located.
Specifically, in the automatic network selection mode, the modem of the mobile terminal automatically obtains the information of the available operator network at the current location from the network service terminal, such as the base station, and there are multiple accessible networks, and when the manual network selection mode is not switched, the modem will select the PLMN access with the highest supported wireless access priority.
However, if the mobile terminal still uses the automatic network selection mode when entering the roaming area, the mobile terminal resides in the VPLMN due to the switching of the network services of the base stations in different areas, and the home PLMN or the equivalent local PLMN cell is periodically searched, which causes the increase of the power consumption of the mobile terminal, and particularly affects the use of the user when the power of the mobile terminal is insufficient.
Therefore, in the embodiment of the present invention, after obtaining the available operator network information, the mobile terminal further determines whether to enter the roaming area, i.e., performs step S2 below.
Step S2, determining whether the mobile terminal enters the roaming area according to the currently available operator network.
The roaming region may be a region or a country other than the home location of the subscriber identity module in the mobile terminal.
Specifically, the modem of the mobile terminal obtains the local home network of the subscriber identity module, compares the current available operator network of the current location with the local home network, and if the home location of the current available operator network is different from that of the local home network, the current location of the mobile terminal is considered as a roaming place, that is, the mobile terminal enters a roaming area, otherwise, the home location of the available operator network is the same as that of the local home network, the current location is local, and the step S1 is returned.
And step S3, determining that the mobile terminal enters the roaming area, and sending a prompt message for prompting the user to start the manual network selection mode.
Specifically, when the modem of the mobile terminal recognizes that the current location is a roaming place, that is, the mobile terminal enters a roaming area, the modem prompts the user to start a manual network selection mode, that is, prompts the user to switch the network selection mode from an automatic network selection mode to a manual network selection mode. For example, the modem reports to the AP side of the mobile terminal, and the AP side pops up a prompt box through a display unit of the mobile terminal to remind the user, or prompts the user through other manners, for example, lighting through a lighting part or sounding through a buzzer, and then the user finds prompt information, and can start a manual network selection mode through an input unit of the mobile terminal, that is, the network selection mode is switched from the automatic network selection mode to the manual network selection mode.
Therefore, the mobile terminal recognizes that the mobile terminal enters the roaming area, and by sending the prompt message for starting the manual network selection mode, even if the user forgets or cannot start the manual network selection mode, the manual network selection mode can be started in time through the prompt message, so that the energy consumption of the mobile terminal caused by frequent network searching is reduced. In addition, the mobile terminal can be prevented from selecting a poor VPLMN network by adopting an automatic network selection mode in a roaming area, so that the quality of a service network is ensured.
Further, in some embodiments, the mobile terminal provides a prompt message for starting the manual network selection mode to the user, and the user confirms whether to switch to the manual network selection mode through an input unit of the mobile terminal, such as a keyboard or a touch screen, for example, and selects "yes" or "no" through the prompt box. As shown in fig. 3, the network selection method according to the embodiment of the present invention further includes the following steps:
in step S4, a confirmation instruction to start the manual network selection mode is received.
Specifically, the user finds the prompt information of the mobile terminal, selects and starts the manual network selection mode through the input unit, and at the moment, the mobile terminal detects the input information of the user, namely receives a confirmation instruction for starting the manual network selection mode.
And step S5, sorting the current available operator networks according to the wireless access priority supported by the mobile terminal to form a current available operator network list.
The list may include unique identification information of the currently available operator network, such as a name, a physical address, or custom information.
Specifically, the modem of the mobile terminal searches for networks and reports available operator networks. In an embodiment, the searched PLMNs that have contracted a roaming agreement with the local home network, that is, the currently available operator networks, are sorted according to RAT (radio access technology) priorities supported by the mobile terminal, and the available operator network with the highest priority is ranked at the top, thereby forming a list of the currently available operator networks.
Step S6, a list of currently available operator networks is provided to the user.
After switching to the manual network selection mode, the user can manually select the most advanced network from the current available operator network list provided by the mobile terminal, and especially for the user who does not know the mobile network, the user can select a better network to use, so that the network quality is ensured.
In some embodiments, after forming the current available operator network list, the mobile terminal marks the operator network with the highest wireless access priority supported by the mobile terminal in the current available operator network list, for example, highlighting the operator network or adopting different fonts or thickening the operator network, and then, the marked current available operator network list is improved to the user, so that the user can easily see the optimal network information, and the method is more intuitive and clear, and is convenient for the user to select a better operator network in a manual network selection mode, and the network quality of the manual network selection is ensured.
In some embodiments, in providing a list of currently available operator networks to a user, the user may manually select an operator network from the list for access by the mobile terminal. However, according to the requirements of 3GPP 23.122, once the user uses the manual network selection mode, unless the mobile terminal is powered back on, when the selected PLMN is unavailable or no equivalent PLMN to the selected PLMN is available, the EHPLMN or HPLMN camp registration is selected to acquire the network service. In other scenarios, the mobile terminal may always search the PLMN manually selected by the user for residing to obtain the service of selecting the PLMN network, and thus, when the mobile terminal enters a place without the selected PLMN network, the mobile terminal may not always search the PLMN network manually selected by the user, may not always obtain the network service, and is always in the off-line state. Therefore, in the embodiment of the present invention, in the manual network selection mode, when the network signal selected manually is not good or there is no network coverage cell, the mobile terminal may also remind the user to ensure the smoothness of the network service, which is described in detail below.
As shown in fig. 3, the network selection method according to the embodiment of the present invention further includes the following steps:
in step S7, a selection instruction for selecting a target operator network in the currently available operator network list is received.
For example, the mobile terminal displays the currently available operator networks through the display unit, and the user selects an operator network from the list through the input unit, for example, selects the operator network arranged at the top in the list, or selects the operator network marked in the list, and the selected operator network is the target operator network.
Step S8, acquiring a network signal of the target operator network in the first network type.
The network standard, i.e. the type of the network, may include, but is not limited to, 3G, 4G, and 5G, or CDMA (Code Division Multiple Access), GSM (Global System for Mobile communications), etc. according to different classification methods.
In an embodiment, the first network type may be one of network types supported by the mobile terminal, and for example, the first network type may be a default network type, a common network type, or a set network type, and is not limited specifically herein. The network signal reflects the network quality.
Specifically, the user selects a target operator network from the current available operator network list, the mobile terminal sends a request signal for accessing the target operator network to the base station at the current location, and acquires a network signal of the target operator network to judge the network quality.
Step S9, if it is determined that the network signal of the target operator network is smaller than the signal threshold, a prompt message to reselect the target operator network is sent.
Specifically, the mobile terminal obtains a network signal of the target operator network, and if the network signal is smaller than the signal threshold, it is determined that the network quality of the selected target operator network is poor, and a prompt message may be sent through the display unit, for example, to prompt the user to select that the network signal is poor, and to ensure the communication quality, please reselect the target operator network. Otherwise, if the network signal is greater than or equal to the signal threshold, determining that the network quality of the selected target operator network is better, and continuing to register the target operator network.
Therefore, in the manual mode, when the network signals of the current network standard of the operator network selected by the user are not good, namely, the network signals are all weak signal cells, the user is reminded to reselect the operator network to reside, and the network quality and the communication quality of the mobile terminal access network can be ensured.
As described above, if the user finds the prompt information for reselecting the target operator network, the reselection or non-reselection may be selected through the input unit of the mobile terminal, as follows.
At step S10, a negative instruction to reselect the target carrier network is received. I.e., the user does not want to reselect the target operator network, the mobile terminal performs the following step S11. And receiving a positive instruction of reselecting the target operator network, searching the network again and generating a current available operator network list to provide the current available operator network list for the user.
Step S11, detecting an available network coverage cell of the selected target operator network in the second network type. If the available network coverage cell, referred to as an available cell, is detected, the following step S12 is performed, otherwise, if the available network coverage cell is not detected, the following step S13 is performed.
Step S12, if it is not detected that the target operator network covers the cell in the available network of the second network type, sending a prompt message for reselecting the target operator network.
The second network system may be other network systems besides the first network system.
Specifically, the modem side of the mobile terminal detects that the target operator network has no available cell in the second network type, and may report the cell to the AP side of the mobile terminal, and the AP side may pop up a prompt box through the display unit, for example, to prompt "do you select an operator network that has no available cell detected, and in order not to affect normal operation of the mobile terminal, whether to reselect a new operator network" is prompted to the user to reselect the operator network.
Therefore, when the manually selected target operator network has no available cell, the user can be reminded in time, and the user can switch the network in time by seeing the reminding information, so that the mobile terminal is prevented from being in a network service-free state.
Step S13, if it is detected that the target operator network is in the available network coverage cell of the second network type, the target operator network resides in the available network coverage cell of the second network type.
Further, as shown in fig. 3, the network selection method according to the embodiment of the present invention further includes the following steps:
at step S14, a positive instruction to reselect the target carrier network is received, the current available carrier network is re-searched, and a list of available carrier networks is generated to provide to the user. Further, the user may reselect the target operator network from the list, i.e. return to step S7, until the mobile terminal camps on the available cell, ensuring the communication network service.
And step S15, receiving a negative instruction of reselecting the target operator network, and automatically switching the network selection mode from the manual network selection mode to the automatic network selection mode.
Specifically, the mobile terminal receives the negative instruction of reselecting the target operator network for multiple times, that is, the user does not reselect the target operator network all the time, which is easy to cause that the mobile terminal is in a state without network service all the time.
Further, some users may forget to turn off the manual network selection mode when leaving the roaming scenario, the mobile terminal may not automatically switch back to the automatic network selection mode, and may not automatically search again to select an available VPLMN cell for residence, and at this time, if the PLMN selected by the user does not have an available cell, the mobile terminal may be in a no-service state, which may affect user experience.
In order to solve the above problem, in the embodiment of the present invention, as shown in fig. 3, after determining that the network signal of the selected operator network is smaller than the signal threshold, the network selection method further includes:
step S16, detecting that the currently available operator network is switched to the local home network configured by the subscriber identity module in the mobile terminal.
Specifically, the mobile terminal enters a roaming handover to a manual network selection mode and accesses a manually selected target operator network to maintain network service. The mobile terminal detects the available operator network at the current location in real time, compares the available operator network with the local home network, and when the available operator network at the current location is determined to be switched to the local home network, namely the mobile terminal leaves a roaming place, if the mobile terminal still resides in the manually selected target operator network, at the moment, when the resident network cell does not exist, the mobile terminal is in a non-service state, and the use is influenced. Therefore, in the embodiment of the present invention, when it is detected that the mobile terminal leaves the roaming place, the following step S17 is performed.
And step S17, automatically switching the network selection mode from the manual network selection mode to the automatic network selection mode, or sending prompt information for switching the network selection mode from the manual network selection mode to the automatic network selection mode.
Specifically, after leaving the roaming area, the mobile terminal automatically switches to the automatic network selection mode or sends out prompt information for switching the automatic network selection mode, and the user finds that the prompt information can select to start the automatic network selection mode. Therefore, the problem that no service network exists due to network switching when the mobile terminal leaves a roaming place can be avoided, and the network service of the mobile terminal is ensured.
Further, the user finds the prompt message for switching the network selection mode from the manual network selection mode to the automatic network selection mode, and if the user does not select to start the automatic network selection mode, the mobile terminal returns to the step S11 mentioned above, that is, the selected target operator network is detected again in the available network coverage cell of the second network type, and the mobile terminal is reminded or resided according to the detection result and the content above until the mobile terminal resides in the available network. If the user selects to start the automatic network selection mode, that is, receives a positive command to execute step S18, the mobile terminal closes the manual network selection mode and starts the automatic network selection mode to ensure that the mobile terminal is in a network service state.
To sum up, the network selection method of the embodiment of the invention mainly overcomes the defects of the existing manual network selection function, and can automatically inform the user to switch the network selection mode into the manual network selection mode when the user enters the roaming area; when the operator network manually selected by the user cannot acquire the service, the user is informed to reselect a new proper PLMN for residing, for example, the operator network selected by the user can prompt the user to select other operator networks when the first selected network mode cannot find the available network coverage cell, if the user still continuously requires to select the operator network service, the user can further search other network modes for network coverage cells which can reside and register, and when each network mode of the selected operator network cannot search the available cell, the user can be reminded to replace the operator network again, so that the mobile terminal service is prevented from being influenced; in addition, when the mobile terminal leaves the roaming place, the automatic network selection mode is automatically switched to or the user is reminded to start the automatic network selection mode, so that the situation that the manual network selection mode is forgotten to be closed when the mobile terminal leaves the roaming place can be avoided, and the network service of the mobile terminal can be ensured.
In short, the network selection method of the embodiment of the invention adds a prompt function in the network selection process, so that the user can start the manual network selection mode in time when entering the roaming place, and the power consumption of the mobile terminal in the roaming place is reduced. In addition, when the mobile terminal leaves the VPLMN service area, the available PLMN registration can be switched in time to acquire service, so that the advantage of a manual network selection mode can be enjoyed, and the user experience is improved.
