Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

Fig. 1 is a flowchart of a network searching method according to an embodiment of the present disclosure. The network searching method is suitable for network searching of the narrow-band Internet of things terminal or other terminals, and is particularly suitable for network searching when data service cannot be normally initiated under the condition of weak signal or no signal coverage. Fig. 2 shows a schematic block diagram of a terminal. As shown in fig. 2, the terminal includes a modem 23, a location module 22, and an application service layer 21. The modem 23 is a baseband module and is a core module for the terminal to provide mobile communication. The positioning module 22 provides a positioning function, supports a Global Positioning System (GPS) or a beidou positioning function, and provides Position information for the terminal. The application service layer 21 provides the user's implementation of the requirements, interacting bi-directionally with the location module 22 and the modem 23, respectively.

As shown in fig. 1, the search method according to an embodiment of the present disclosure includes the following steps S11 to S12.

In step S11, an emergency level of a data service to be initiated and a remaining power level of the terminal are acquired.

In some embodiments, the data service to be initiated may be classified into 3 classes, such as a very urgent class, a general urgent class, and a non-urgent class, according to the degree of urgency. A very urgent class may be defined as a situation where data services, such as sending a distress signal, must be initiated even if the battery of the terminal is drained. A general urgency level may be defined as a certain urgency of data service, such as when the location of the mail terminal is not updated timely and has not been sent to the server for a long time. The non-urgency level may be defined as when the data service is not initiated for a while and is acceptable, such as when the location of the terminal first updates the server.

The emergency ranking of the data service may be defined by a service layer program of the terminal and the emergency ranking of the data service to be initiated may be determined by the service layer program of the terminal and communicated to the modem when the data service is initiated, or the emergency ranking of the data service to be initiated may also be determined by the modem.

In some embodiments, the remaining power of the terminal is divided into a minimum power level, a smaller power level, and a normal service power level according to the available margin. The minimum power level refers to a network searching which can only initiate data service of a very urgent level, and can not initiate data service of a general urgent level and a non-urgent level. The smaller electric quantity level refers to the network searching which can only initiate data service of a very urgent level and a general urgent level, and can not initiate data service of a non-urgent level. The normal service power level refers to a network search that can initiate data services of all emergency levels. For example, a minimum charge level may be defined as a battery available margin of less than 3%, and a smaller charge level may be defined as a battery available margin of less than 8% but greater than 3%, depending on the product, by way of example only.

The division of the remaining power level may be defined by a service layer program of the terminal, and the determination of the current remaining power level may be determined by the service layer program of the terminal and communicated to the modem upon initiation of the data service, or may be determined by the modem.

In step S12, it is determined whether to initiate a network searching process based on the emergency level and the remaining power level of the data service to be initiated.

In some embodiments, the network searching process is determined to be initiated in at least one of: (1) the emergency level of the data service to be initiated is a very emergency level, which indicates that the data service is very emergency, and the data service must be initiated even if the battery power of the terminal is exhausted; (2) the emergency level of the data service to be initiated is a general emergency level, the residual electric quantity level is a small electric quantity level or a normal service electric quantity level, the situation indicates that the data service has certain urgency, and the data service can be initiated under the condition that the available electric quantity of the battery allows; (3) the emergency level of the data service to be initiated is a non-emergency level, and the residual power level is a normal service power level, which indicates that the data service is not emergency, and the data service can be initiated when the available power of the battery is sufficient.

In some embodiments, the network searching process is determined not to be initiated in at least one of: (1) the emergency level of the data service to be initiated is a general emergency level, and the residual electric quantity level is a minimum electric quantity level, which indicates that the available electric quantity of the battery is small enough and the electric quantity of the battery needs to be saved as much as possible; (2) the emergency level of the data service to be initiated is a non-emergency level, and the remaining power level is a minimum power level or a smaller power level, which indicates that the data service is not emergency, and the available power of the battery is insufficient, so that the power of the battery needs to be saved.

As shown in fig. 3, first, in step S201, the modem access layer performs cell selection and cell reselection, and if no available network resides, it is finally determined to be offline, and the process goes to step S202.

In step S202, the application service layer has a data service to initiate, and determines the urgency level of the data service, which may be performed by the modem. During this time, if the battery level and the location information are changed, the modem should be notified. If the emergency level is an emergency level, the process proceeds to step S203, if the emergency level is a general emergency level, the process proceeds to step S204, and if the emergency level is a non-emergency level, the process proceeds to step S205.

In step S203, a data service with an emergency level being a very emergency level is initiated, the modem is requested to transmit data, and the process goes to step S208.

In step S204, a data service with an emergency level of a general emergency level is initiated, the modem is requested to transmit data, and the process goes to step S206.

In step S205, a data service with an emergency level as a non-emergency level is initiated, the modem is requested to transmit data, and the process goes to step S207.

In step S206, the modem determines whether to initiate a network search according to the current power headroom. If the remaining power level is the minimum power level, go to step S209, if the remaining power level is the smaller power level, go to step S208, if the remaining power level is the normal service power level, go to step S208.

In step S207, the modem determines whether to initiate a network search according to the current power headroom. If the remaining power level is the minimum power level, go to step S209, if the remaining power level is the small power level, go to step S209, if the remaining power level is the normal service power level, go to step S208.

In step S208, enter the web searching process entry and initiate the web searching process.

In step S209, network searching is not initiated, and data transmission fails.

In some embodiments, after determining to initiate the network searching process, the method according to an embodiment of the present disclosure may further include:

if the current position of the terminal is located in a preset radius range taking the normal position of the terminal as an origin, searching a mobile network which is Registered by the terminal last time, wherein the mobile network which is Registered by the terminal last time can be a Registered public land mobile network (Registered-PLMN, RPLMN) and an Equivalent home mobile network (Equivalent-HPLMN, EHPLMN); or

If the current location of the terminal is outside the preset radius range using the normal location of the terminal as the origin, the mobile networks (e.g., RPLMN and EHPLMN) registered by the terminal last time are searched, then the User Controlled mobile network (User Controlled PLMN, UPLMN) and the Operator Controlled mobile network (Operator Controlled PLMN, OPLMN) are searched, and finally the full-band mobile network is searched.

The current location of the terminal may be obtained by a positioning device such as a GPS or beidou satellite, which may be calculated by a service layer program of the terminal and notified to the modem when initiating data services.

The frequently-located position of the terminal is the center of N times of coordinate sampling, wherein N is more than or equal to 2, and the value of N can be determined according to an actual application scene. The center can be calculated in many ways, for example, the coordinate samples of N times can be averaged, or the root mean square value can be taken, etc.

The preset radius can be the coverage distance of the narrowband internet of things base station. For a static terminal, only the network searching needs to be carried out within a preset radius range; for a mobile terminal, an origin of a location is calculated according to the location coordinates of the terminal, a preset radius range with the origin as a center is determined, and then a network is searched by using the network searching method described above.

The RPLMN is the last registered network and is also typically a common network. The EHPLMN is an equivalent home mobile network and may be several networks including the home network, and typically the RPLMN is also one of the EHPLMNs. The UPLMN is a user-controlled mobile network, and the list of networks used by the user is edited and generally used less frequently. The OPLMN is an operator controlled mobile network, an operator managed available network.

By adopting the technical scheme, the appropriate network searching type can be determined by combining the current position of the terminal under the condition that the network searching is needed, unnecessary network searching is reduced, and the power consumption of the battery is reduced to the maximum extent.

In some embodiments, a method according to embodiments of the present disclosure may further include: the search is stopped after the number of searches (i.e., the number of network search attempts) reaches a preset number, wherein the preset number is determined based on the emergency level and the remaining power level of the data service to be initiated.

That is, the network searching method according to the embodiment of the present disclosure further defines a network searching attempt number attribute, and the usage principle is that network searching can be attempted a small number of times for the emergency data service, the number of attempts is controlled for the case of low power consumption, and the number of network searching attempts is increased for the emergency data service when the power consumption is sufficient. The specific control mode is as follows:

1) if the emergency level of the data service is a very emergency level or a general emergency level, and the remaining power level is a minimum power level or a small power level, the network searching attempt number is C-2;

2) if the emergency level of the data service is a very emergency level or a general emergency level and the residual electric quantity level is a normal service electric quantity level, the network searching attempt time is C > 2;

3) and if the emergency level of the data service is the non-emergency level, the network searching attempt number is C equal to 1.

Through the technical scheme, the network searching can be avoided being carried out ceaselessly by defining the network searching attempt times, and the electric quantity of the battery is saved.

In some embodiments, a method according to embodiments of the present disclosure may further include: and timing a search time interval between two searches, wherein the search event interval when the preset times are equal to 1 is larger than the search time interval when the preset times are larger than 1. That is, if a search for a network needs to be attempted again in a short time, i.e., C >1, then a shorter time interval T0, such as 5 seconds, is used; if no network search is attempted for a short time, i.e. C ═ 1, then a longer time interval T1 is used, such as 5 minutes or 30 minutes, depending on the specific application scenario of the terminal.

By adopting the technical scheme, a proper network searching time interval can be set, for example, under the condition of weak signal or no signal coverage, if the emergency level of the data service is a very emergency level or a general emergency level, a shorter searching time interval can be used because the network searching needs to be tried for many times in a short time, and if the emergency level of the data service is a non-emergency level, the situation is that no network exists, so that the longer searching time interval can be used, the frequent network searching can be avoided, and the battery power can be saved.

First, in step S301, the modem enters a network searching process.

In step S302, the current location range is determined according to the current location of the terminal, and if the current location range is within the preset radius range with the normal location as the origin, the network searching type I is executed, that is, steps S303 and S304 are executed, otherwise, the network searching type II is executed, that is, steps S305 to S309 are executed.

In step S303, the RPLMN is searched, and if there is no RPLMN or the RPLMN search fails, the process goes to step S304, and if an available network is searched, the process goes to step S311 for residing.

In step S304, an attempt is made to search all PLMNs other than the RPLMN of the EHPLMN, and if a network is searched, the network resides, otherwise, the process goes to step S310 and moves to a no network state.

In step S305, the RPLMN is searched, and if there is no RPLMN or the RPLMN search fails, the process goes to step S306, and if an available network is searched, the process goes to step S311 for residing.

In step S306, an attempt is made to search all PLMNs different from the RPLMN of the EHPLMN, and if no available network is searched or the search fails, the process goes to step S307, and if an available network is searched, the process goes to step S311 for camping.

In step S307, an attempt is made to search for the UPLMN, and if no available network is found or the search fails, the process goes to step S308, and if an available network is found, the process goes to step S311 for residing.

In step S308, search for OPLMN, go to step S309 if no available network is searched for or the search fails, and go to step S311 to reside if an available network is searched for.

In step S309, full band search is performed, and the searched networks are attempted to reside in sequence according to the signal quality, if the residence is successful, a registration process is performed, otherwise, step S310 is executed and the network-free state is moved to.

In step S310, the network-less state is migrated, and then, if the number of network searching attempts C >1, the modem starts a smaller retry timer T0 (i.e. a smaller searching time interval is used) to wait for the next network searching again; if the network searching attempt number C is 1, the modem starts a longer retry timer T1 (i.e., using a longer searching time interval) and waits for the next network searching again. It is effective for the mobile terminal to re-search for a network next time, and there is a possibility that the terminal moves from an area with a poor signal to an area with a network. The time of the timer T should depend on the type of terminal, e.g. the car should be shorter than the time of the bicycle.

By adopting the technical scheme, the terminal can select a proper network searching type by combining the current position of the terminal under the condition of no network service, so that an available network can be searched as soon as possible, unnecessary network searching is reduced, the power consumption is reduced to the maximum extent, the battery endurance is improved, and the data service experience is not influenced.
