Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further 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 present application and are not intended to limit the present application.
The following describes in detail the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems by embodiments and with reference to the drawings. The following embodiments may be combined with each other and may not be described in detail in some embodiments for the same or similar concepts or processes.
The technical means described in the embodiments of the present application may be arbitrarily combined without conflict.
The embodiment of the application provides a network searching method which is applied to a terminal. The specific type of the terminal is not limited in this embodiment, and may be any user equipment, for example, a smart phone, a personal computer, a notebook computer, a tablet computer, a portable wearable device, and the like.
Fig. 1 is a schematic flowchart of a network searching method according to an embodiment of the present application. As shown in fig. 1, in the embodiment of the present application, the network searching method mainly includes the following steps:
s101, under the condition that a target geographic position in a second country is reached from a first country, acquiring a target Public Land Mobile Network (PLMN) to be searched and a network searching frequency point supported by the target PLMN at the target geographic position; the target PLMN is a PLMN of an operator for which the home operator of the terminal desires registration in the second country.
In the embodiment of the application, the terminal acquires the target PLMN and the network searching frequency point supported by the target PLMN at the target geographic position under the condition that the terminal reaches the target geographic position in the second country from the first country.
It should be noted that, in the embodiment of the present application, the first country and the second country are different countries, that is, the network searching method provided in the embodiment of the present application actually supports a scenario in which the terminal roams across borders. The specific first country and the second country may be determined according to an actual application scenario, and the embodiment of the present application is not limited.
It should be noted that, in the embodiment of the present application, in general, when a country arrives at another country, the first place of arrival is an airport, and therefore, the target geographic location in the second country may be a location where an airport in the second country is located, or of course, may be a specific geographic location in the second country, and the embodiment of the present application is not limited.
It can be understood that, in the embodiment of the present application, a home operator of a terminal is actually an operator to which a Subscriber Identity Module (SIM) used on the terminal belongs, and for different home operators, contracted operators in different countries are different, and accordingly, operators that the terminal expects to register in different countries are also not completely the same, and PLMNs of the operators that expect to register are also different, so that the terminal needs to acquire a PLMN of an operator that the home operator expects to register in a second country, so as to directly perform a search for the PLMN in the following process, thereby improving network searching efficiency and accuracy.
It should be noted that, in the embodiment of the present application, for a second country, there is a difference between frequency points at which different geographic locations of the second country can quickly search for a PLMN of the second country, and therefore, the terminal may further store a network searching frequency point supported by the target operator network at the target geographic location in advance, so that when performing network search at the target geographic location, the network searching efficiency is improved.
It should be noted that, in an embodiment of the present application, the home operator may be one or more operators expected to be registered in the second country, and correspondingly, the target PLMN may be a network searching frequency point supported by one operator expected to be registered in the target geographic location, or may include a network searching frequency point supported by each operator in the multiple operators expected to be registered in the target geographic location, and the network searching frequency point may include different Radio Access Technologies (RATs), for example, supported by 5G New air interfaces (New, Radio, NR), Long Term Evolution technologies (Long Term Evolution, LTE), Universal Mobile Telecommunications Systems (UMTS), Global System for Mobile Communications (GSM), and the like, and the embodiment of the present application is not limited.
It should be noted that, in the embodiment of the present application, the target PLMN and the network searching frequency point supported by the target PLMN in the target geographic location may be written into a Non-Volatile Memory (NVM) of the terminal in advance, so that the target PLMN written in the NVM may actually be information such as an identifier of the target PLMN, and the terminal reads the information from the NVM, that is, may know that the network to be searched is the target PLMN. In addition, the above information may also be stored in advance in other devices of the terminal, and the embodiment of the present application is not limited.
It should be noted that, in the embodiment of the present application, before the terminal acquires the target PLMN to be searched and the network searching frequency point supported by the target PLMN in the target geographic location, the following steps may also be performed: acquiring a network search identifier; correspondingly, the terminal acquires a target network PLMN to be searched and a network searching frequency point supported by the target PLMN at a target geographic position, and the method comprises the following steps: and under the condition that the network search identifier indicates to execute the optimized network search, acquiring a target PLMN to be searched and a network searching frequency point.
It can be understood that, in the embodiment of the present application, a network search identifier may be preset in the terminal, if the network search identifier indicates to perform optimized network search, the terminal performs acquisition of a target PLMN to be searched and a network search frequency point for performing network search quickly, and if the network search identifier indicates not to perform optimized network search, the terminal performs network search in a conventional network search manner.
And S102, searching a target PLMN on the network searching frequency point.
In the embodiment of the application, after the terminal reaches the target geographic position in the second country, the target PLMN to be searched is determined, and the target PLMN can be searched on the network searching frequency point after the network searching frequency point supported by the target PLMN at the target geographic position.
It can be understood that, in the embodiment of the present application, the target PLMN and the network searching frequency point are actually determined according to the current location of the terminal, that is, the second country, and the target geographic location, so that the target PLMN search is directly performed on the network searching frequency point during network search, and is matched with an actual scene, and the network search range is small, so that PLMN search can be performed quickly, PLMN access can be quickly achieved, and the accessed target PLMN is a PLMN of an operator expected to be registered, which not only improves the network search efficiency, but also improves the accuracy of network search.
It should be noted that, in the embodiment of the present application, before searching for a target PLMN on a network searching frequency, the terminal may further perform the following steps: carrying out validity detection on the network searching frequency point and the target PLMN; correspondingly, the terminal searches the target PLMN on the network searching frequency point, and the method comprises the following steps: and under the condition that the network searching frequency point and the target PLMN are effective, searching the target PLMN on the network searching frequency point.
It can be understood that, in the embodiment of the present application, before searching for a target PLMN at a network searching frequency point, a terminal may first detect whether the network searching frequency point and the target PLMN are valid, and if valid, may normally perform a search for the target PLMN at the network searching frequency point, and if invalid, for example, there is no network searching frequency point and/or there is no target PLMN, it is practically impossible to search for the target PLMN at the network searching frequency point, and therefore, the search for the target PLMN at the network searching frequency point will be prohibited, and an invalid network search operation is avoided.
In the embodiment of the present application, after the terminal searches for the target PLMN on the network searching frequency point, the following steps may be further performed: and initiating registration to the target PLMN under the condition that the target PLMN is searched on the network searching frequency point.
It can be understood that, in the embodiment of the present application, if the terminal successfully searches for the target PLMN on the network searching frequency point, the terminal may directly perform network registration to implement network access.
In the embodiment of the present application, after the terminal searches for the target PLMN on the network searching frequency point, the following steps may be further performed: under the condition that the target PLMN is not searched on the network searching frequency point, a network searching frequency band supported by the target PLMN is obtained; and searching the target PLMN on the network searching frequency band.
It should be noted that, in the embodiment of the present application, the terminal searches for the target PLMN at the network searching frequency point, and may also not search for the target PLMN because the information is not accurate enough, in this case, the terminal may obtain all frequency bands supported by the target PLMN, that is, the network searching frequency band, and then perform the search for the target PLMN on the network searching frequency band. The terminal searches for the target PLMN on the network searching frequency band, which actually enlarges the range of searching for the target PLMN so as to be able to search. And the network searching frequency band comprises the network searching frequency points. The specific network searching frequency band is determined by the target PLMN, and the embodiment of the present application is not limited.
In the embodiment of the present application, after the terminal searches for the target PLMN on the network searching frequency band, the following steps may be further performed: under the condition that the target PLMN is not searched on the searched network frequency band, acquiring a network frequency band supported by the terminal in a second country; and searching the network frequency band for the PLMN allowing the terminal to register.
It should be noted that, in the embodiment of the present application, the terminal searches for the target PLMN on the network searching frequency band, and may also not search for the target PLMN due to some reasons, in this case, the terminal may acquire all frequency bands supported by the terminal in the second country, that is, the network frequency band, so as to perform network search on the network frequency band. Here, the terminal may search for any PLMN allowed to be registered in the network band, as long as the PLMN can be searched, and the search target PLMN is not limited, so that the terminal can provide network services, thereby actually further expanding the network search range. Specific network frequency bands are not limited in the embodiments of the present application.
It should be noted that, in the embodiment of the present application, the network searching band and the network band may be preferentially stored in the NVM of the terminal, and the terminal may directly obtain the network searching band and the network band from the NVM when the terminal needs to be used.
It should be noted that, in the embodiment of the present application, a Baseband Processor (BP) included in the terminal, that is, a processing unit providing communication capability in the terminal, and steps S101 and S102, as well as related steps of the network search involved, may all be executed by the BP.
Fig. 2 is a schematic diagram of an exemplary network search process provided in an embodiment of the present application. As shown in fig. 2, the terminal determines whether to perform an optimized network search when reaching a target geographic location of a second country, that is, an airport of the second country, performs a conventional network search when the optimized network search is not performed, reads, from the NVM, a PLMN, that is, a target PLMN, which is an operator whose home operation is expected to be registered in the second country, and a network searching frequency point supported by the target PLMN at the target geographic location when the optimized network search is performed, then starts a first-stage network search, that is, searches for the target PLMN at the network searching frequency point, if found, initiates registration, if not found, starts a second-stage network search, that is, searches for the target PLMN at a network frequency band supported by the target PLMN, if found, initiates registration, and if not found, starts a third-stage network search, i.e. network search is performed on all frequency bands supported by the terminal in the second country, i.e. the network frequency band.
Fig. 3 is a timing diagram of an exemplary network search according to an embodiment of the present application. As shown in fig. 3, when the terminal reaches the target geographic location in the second country, after the network search is started, the network search in the first stage may be performed on the network searching frequency point for searching the target PLMN in a very short time, and then, if the target PLMN is not searched, the network search in the second stage is performed, the time in the stage is longer than that in the first stage, and the search range is wider, and then, if the target PLMN is not searched, the network search in the third stage is performed, the time in the stage is longer than that in the second stage, and the search range is wider. In addition, as shown in fig. 3, RATs corresponding to frequency bands of each frequency point may be different, such as NR, LTE, UMTS, and GSM.
In the embodiment of the present application, in step S101, the terminal actually needs to collect the target PLMN and the network searching frequency point supported by the target PLMN at the target geographic location in advance, and details of the relevant information collection process are described below.
In the embodiment of the present application, when the terminal reaches the target geographic location in the second country from the first country, the terminal may acquire the target PLMN to be searched, and before the network searching frequency point supported by the target PLMN at the target geographic location, perform the following steps: sending the target geographical position and the attribution operator to a server; and the receiving server determines the target PLMN and the network searching frequency point by utilizing the network searching information acquired based on the target geographic position and the home operator.
It should be noted that, in the embodiment of the present application, the target PLMN and the network searching frequency point are determined and stored by the server, and the terminal interacts with the server to obtain these pieces of information. The server is used for acquiring and analyzing information according to the target geographic position and the home operator provided by the terminal, so that the target PLMN and the network searching frequency point are determined.
Specifically, in the embodiment of the present application, the server may obtain the target PLMN based on the following manners: first, corresponding Operator information is obtained from an Operator Controlled PLMN Selector with Access Technology set by an Operator in a SIM card of a terminal, the Operator information is summarized and collated with Roaming indication function (SOR) information sent by a network home Operator, and a subscription Operator of the home Operator in a second country and an Operator expected by the subscription Operator are obtained from the obtained Operator information, so as to select a priority list. When an operator in the second country is present in the home operator selection priority list, the home operator's chances of camping on the operator in the country may be weighted, so that the operator that the home operator desires to register in the second country may be selected from the selection priority list, and the target PLMN may be determined. For example, when PLMN-A appears in the SIM card file OPLMN of the user whose home operator is PLMN1, or PLMN-A appears in the OPLMN list carried by the SOR information received when the user registers in the roaming country, the user whose home operator is PLMN1 will be given more opportunities to register on the network of PLMN-A; second, the server may cooperate with the home operator to obtain an operator provided by the home operator who desires to register in a second country, thereby determining the target PLMN.
Specifically, in the embodiment of the present application, the server may obtain the network searching frequency point supported by the target PLMN at the target geographic location based on the following manner: firstly, the frequency point PLMN information can be recorded and uploaded after the user actually starts up at an airport and registers to the network, so that data updating is carried out. The server datA update mode may adopt A weighted mode, for example, the target geographic location is an airport in the second country, the target PLMN is PLMN-A, and the information that the user uploads A network found at the airport for the first time is: the frequency point of A user with the home PLMN being PLMN1 on the 5G network of PLMN-A is F1, so that the user with the home PLMN can be weighted on the frequency point of F1 of the PLMN-A network, and A plurality of frequency points with higher weighted value rank are stored at the server end to be used as the network searching frequency points of the PLMN-A at the airport. Secondly, collecting frequency points used by different operators for network deployment at a target geographic position by a test team; and thirdly, the frequency points used by the operator in the target geographic position for network deployment are obtained through cooperation with the operator.
Illustratively, the target geographic location is an airport 1, and the server may specifically record the relevant information according to the following table 1:

It should be noted that, in the embodiment of the present application, the above methods for acquiring a target PLMN and searching for a network frequency point are only some optional methods provided, and of course, other methods may also be adopted according to actual situations, and the embodiment of the present application is not limited.
In an embodiment of the present application, before the terminal sends the target geographic location and the home carrier to the server, the following steps may be further performed: collecting expected travel information under the condition of being located in a first country; outputting prompt information requesting to confirm whether to execute optimized network search when the target geographical position is reached under the condition of determining the expected arrival target geographical position by using the expected travel information; correspondingly, the terminal sends the target geographic position and the home operator to the server, and the method comprises the following steps: in case an instruction is received confirming execution of the optimized network search, the target geographical location and the home operator are sent to the server.
It can be understood that, in the embodiment of the application, the terminal may determine the position to be reached, that is, the target geographic position in the second country, by collecting the expected travel information of the user, so as to prompt the user whether to perform the optimized network search when reaching the target geographic position, and if so, further trigger to acquire the target PLMN and search for the network frequency point, so as to facilitate subsequent execution of the optimized network search. The specific expected travel information may be schedule reminders set in the terminal, records of purchased tickets stored in the terminal, and the like, and the embodiment of the present application is not limited.
Fig. 4 is a schematic diagram of an exemplary information collection process provided in an embodiment of the present application. As shown in fig. 4, after acquiring the expected travel information, the terminal may display a prompt window on the display interface, display prompt information requesting to confirm whether to execute the optimized network search when reaching the target geographic location in the prompt window, and then provide the home operator and the target geographic location to the server when receiving an instruction confirming to execute the optimized network search, so as to receive information required for searching for a network to reach the target geographic location, which is sent by the server, that is, the target PLMN and its network searching frequency point at the target geographic location, and of course, may further include a network searching frequency band corresponding to the target PLMN, and finally store the information in the NVM.
It should be noted that, in the embodiment of the present Application, the terminal includes an Application Processor (AP), that is, a processing unit for installing an operating system and Application software in the terminal, and the steps of collecting the expected travel information, sending the home operation and target geographic location to the server, and receiving the relevant information may be executed by the AP.

As shown in fig. 4, in the network search framework of the present application, four parts may be involved, which are a user information processing module, a network search information extraction module, an information collection cloud system module, and a network search module, where the user information processing module and the network search information extraction module may be included in an AP of a terminal, the network search module may be included in a BP of the terminal, and the information collection cloud system module may be included in a server.
