Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a network search method and a mobile terminal.
Background
Generally, after a Mobile terminal (such as a Mobile phone, a tablet computer, etc.) is powered on, Public Land Mobile Network (PLMN) search needs to be performed, and a normal service can be obtained from a Network only after a PLMN is successfully registered.
Typically, the mobile terminal will maintain several different types of PLMN lists, each including one or more PLMNs. For example, the PLMN list maintained by the mobile terminal may include Registered PLMNs (Registered PLMNs, RPLMNs), Equivalent PLMNs (Equivalent PLMNs, EPLMNs), Home PLMNs (Home PLMNs, HPLMNs), Equivalent Home PLMNs (EHPLMNs), and the like.
In practice, it is found that when the mobile terminal is in a roaming state, the mobile terminal first searches for a PLMN in a PLMN list (e.g., RPLMN, EPLMN, HPLMN, and EHPLMN list) maintained by the mobile terminal during network searching. When none of the PLMNs in the PLMN list is searched, an attempt is made to search for a PLMN of the roaming country. It can be seen that when the mobile terminal is in a roaming state, it takes a long time for the mobile terminal to search for a PLMN in a roaming country.
Disclosure of Invention
The embodiment of the invention provides a network searching method and a mobile terminal, which are beneficial to the mobile terminal to quickly search a proper PLMN.
In a first aspect, an embodiment of the present invention discloses a network search method, including:

if the PLMN of the first cell is not the first PLMN, determining whether a first MCC is the same as a second MCC, wherein the first MCC is the MCC of the first cell, and the second MCC is the MCC in the HPLMN or the MCC in the first PLMN;
and if the first MCC is different from the second MCC, performing network search on the PLMN comprising the first MCC.
In a second aspect, an embodiment of the present invention discloses a mobile terminal, including:
a selection module for selecting a first PLMN;
a judging module, configured to judge whether a PLMN of a first cell is the first PLMN, where the first cell is a searched cell;

a searching module, configured to perform a network search on a PLMN including the first MCC when the determining module determines that the first MCC is different from the second MCC.
In a third aspect, an embodiment of the present invention discloses a mobile terminal, including: the system comprises a communication interface, a memory and a processor, wherein the processor is respectively connected with the communication interface and the memory; wherein the memory is to store program instructions; the processor is used for calling the program instructions stored in the memory to execute the method provided by the first aspect.
Therefore, by implementing the method provided by the implementation of the invention, when the mobile terminal searches the network in the roaming country, the network in the roaming country is searched without searching all PLMNs in the PLMN list. By implementing the method provided by the implementation of the invention, the mobile terminal searches the cell after selecting the first PLMN. And the mobile terminal judges whether the searched PLMN of the first cell is the first PLMN or not. If the PLMN of the first cell is not the first PLMN, whether the first PLMN selected by the mobile terminal is the network of the country where the mobile terminal is currently located can be determined according to the MCC of the first cell, or whether the mobile terminal is located in a roaming country can be determined according to the MCC of the first cell, so that the mobile terminal can search the network of the country where the mobile terminal is currently located in time according to the determination result, and a suitable PLMN can be quickly searched.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.
To facilitate an understanding of embodiments of the present invention, the following description refers to terms of art used in the practice of the present invention:
PLMN (Public Land Mobile Network): networks established and operated by governments or operators approved therefor for the purpose of providing land mobile services to the public. PLMN ═ MCC (Mobile country Code) + MNC (Mobile Network Code). For example, when china is 460, china is 00, and china is 01, the PLMN in china is 46000, and the PLMN in china is 46001.
For a particular terminal, it is often necessary to maintain several different types of PLMN lists, with multiple PLMNs in each list. For example, the PLMN list may include the following:
(1) RPLMN (Registered PLMN ): the PLMN is registered. Is the PLMN that the terminal registered before the last power off or network disconnection. At the TSG TP-21 meeting of 3GPP 2003, the parameter is deleted from the USIM (Universal Subscriber Identity Module) card and stored in the memory of the terminal.
(2) EPLMN (Equivalent PLMN ): the priority of the PLMN which is the same as the PLMN currently selected by the terminal is the same.
(3) EHPLMN (Equivalent Home PLMN ): is a home PLMN which is co-located with the PLMN currently selected by the terminal. For example, the EHPLMN and EPLMN appear to be new 158 networks in transit, while the PLMN appears to be the original 135-139 networks.
(4) HPLMN (Home PLMN): a PLMN to which the end user belongs. That is, the MCC and MNC contained in the IMSI number on the USIM card of the terminal are identical to those on the HPLMN, and for a certain subscriber, there is only one PLMN to which the subscriber belongs.
In existing practical applications, for example, the home country of the mobile terminal is china, and the user goes from china to the united states. After the mobile terminal arrives in the united states, the mobile terminal tries to search the PLMNs in the RPLMN/EPLMN/HPLMN/EHPLMN list for registration when the mobile terminal is powered on to search the network. The network in RPLMN/EPLMN/HPLMN/EHPLMN is the network in China, and the mobile terminal can not search the PLMN in the RPLMN/EPLMN/HPLMN/EHPLMN list in the United states. However, the mobile terminal is able to search for the network in the united states when none of the PLMNs in the RPLMN/EPLMN/HPLMN/EHPLMN list are searched. It can be seen that a mobile terminal requires a long time to search for a suitable network in a roaming country.
In order to shorten the time for a mobile terminal to search for a suitable network in a roaming country, embodiments of the present invention provide a network search method and a mobile terminal. Wherein the network searching method is applicable to the mobile terminal. The Mobile Terminal may include, but is not limited to, a Mobile Terminal (Terminal) such as a Mobile phone (e.g., an Android Mobile phone, an iOS Mobile phone, etc.), a tablet computer, a Mobile Internet Device (MID), a Personal Digital Assistant (PDA), and a vehicle-mounted device. The Mobile terminal may also be referred to as a User Equipment (UE), a terminal, a wireless terminal or a Mobile Station (MS), and the like, which is not limited in the embodiments of the present invention.
The network searching method and the mobile terminal provided by the embodiment of the invention are further described below.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a network searching method according to an embodiment of the present invention. As shown in FIG. 1, the network searching method can include the following parts 101-105, wherein:
101. the mobile terminal selects a first PLMN.
In this embodiment of the present invention, the first PLMN may be any one of an RPLMN, an EPLMN, an EHPLMN, or an HPLMN, or another PLMN network, which is not limited in this embodiment of the present invention. Optionally, the first PLMN may be selected by the mobile terminal according to a preset PLMN priority level. For example, the priority level is: RPLMN is selected first, EPLMN/EHPLMN is selected, HPLMN is selected, and other PLMN is selected. Alternatively, the first PLMN may be manually selected by the user.
102. The mobile terminal searches for a cell.
In the embodiment of the present invention, the PLMN generally consists of a plurality of cells. A cell is the smallest coverage element in a mobile communication network and is uniquely identified by the primary scrambling code (primary scrambling code) used by the cell, which is allocated to the cell at the time of network planning. The information of the PLMN to which the cell belongs is contained in the system message delivered by it.
The purpose of the cell search is to find a cell, although it may not belong to the selected PLMN. Optionally, the cell search step is as follows: the NAS layer of the mobile terminal sends a request for searching the first PLMN to the WAS layer of the mobile terminal, and the WAS layer initiates cell search to find a suitable cell under the first PLMN. Optionally, the WAS layer may send the historical frequency points to the physical layer according to the historical information (assuming that the frequency point information of the cell where the WAS last camped is stored), so that the WAS layer searches for the cell with the strongest signal at the frequency points.
103. The mobile terminal judges whether the PLMN of the first cell is the first PLMN. If the PLMN of the first cell is not the first PLMN, then element 104 is performed.
In the embodiment of the present invention, the first cell is a searched cell. Alternatively, the first cell may be a cell with the strongest searched signal. Or the first cell may be a cell for which the searched signal quality is greater than a preset quality. After searching the first cell, the mobile terminal determines whether the PLMN of the first cell is the first PLMN. Each cell corresponds to a PLMN. The PLMN of the first cell is in the cell broadcast information of the first cell.
Optionally, if the PLMN of the first cell is the first PLMN, determining whether the first cell meets the camping condition, and if the first cell meets the camping condition, executing 106 to camp on the first cell.
In the embodiment of the present invention, if the PLMN of the first cell is not the first PLMN, it indicates that the currently searched network is not the selected network.
104. The mobile terminal determines whether the first MCC is the same as the second MCC. If the first MCC is not the same as the second MCC, then step 105 is performed. Optionally, if the first MCC is the same as the second MCC, the cell search is continuously performed 102.
In an embodiment of the present invention, the first MCC is an MCC of the first cell, and the second MCC may be an MCC in the first PLMN.
If the PLMN of the first cell is not the first PLMN, the MCC of the first cell may not be the same as the MCC of the first PLMN, or the MNC of the first cell may not be the same as the MNC of the first PLMN. The MCC of the first cell is different from the MCC of the first PLMN, indicating that the currently selected first PLMN may not be the network of the current country, and then section 105 is executed to search for the network of the current country in time.
In an embodiment of the present invention, the first MCC is an MCC of the first cell, and the second MCC may be an MCC in the HPLMN.
After judging that the currently searched network is not the selected network, whether the mobile terminal is in a roaming state can be determined in time by judging whether the first MCC is the same as the MCC in the HPLMN. If the mobile terminal is in roaming state, 105, i.e. searching for the network of the country where the mobile terminal is currently located, is performed. Therefore, the network of the country where the mobile terminal is currently located can be searched in time.
105. The mobile terminal performs a network search for a PLMN that includes the first MCC.
In the embodiment of the invention, the network search is carried out on the PLMN comprising the first MCC, namely, the network of the country where the mobile terminal is currently located is searched.
106. And the mobile terminal parks the first cell.
It can be seen that by implementing the method described in fig. 1, the mobile terminal does not need to search for a network in the roaming country, and does not need to search for a network in the roaming country when the search for all PLMNs in the PLMN list is completed. By implementing the method described in fig. 1, the mobile terminal searches for cells after selecting the first PLMN. And the mobile terminal judges whether the searched PLMN of the first cell is the first PLMN or not. If the PLMN of the first cell is not the first PLMN, whether the first PLMN selected by the mobile terminal is the network of the country where the mobile terminal is currently located can be determined according to the MCC of the first cell, or whether the mobile terminal is located in a roaming country can be determined according to the MCC of the first cell, so that the mobile terminal can search the network of the country where the mobile terminal is currently located in time according to the determination result, and a suitable network can be quickly searched.
As an optional implementation manner, if the first MCC is different from the second MCC, the specific implementation manner of the mobile terminal performing the network search on the PLMN including the first MCC may be:
if the first MCC is different from the second MCC, the number of times of the mobile terminal appearing in the first MCC is increased by one. And if the occurrence times of the first MCC are more than the preset times, the mobile terminal searches the PLMN comprising the first MCC for the network.
For example, the first PLMN selected by the mobile terminal is the RPLMN, and the mobile terminal searches for the cell of frequency point 1; the mobile terminal searches a cell 1 with the strongest signal under the frequency point 1; the mobile terminal judges whether the searched PLMN of the cell 1 is RPLMN; if the PLMN of the cell 1 is not the RPLMN, determining whether the MCC (460) of the cell 1 is the same as the MCC (100) of the RPLMN; if the MCC (460) of cell 1 is different from the MCC (100) of the RPLMN, the mobile terminal adds one to the number of MCC (460), the initial number of MCC (460) is 0, and the mobile terminal adds one to the number of MCC (460) to obtain the number of MCC (460) as 1. If the preset times is 1, the appearing times of the MCC (460) is equal to the preset times, and the mobile terminal continues to search the cell. The mobile terminal searches the cell of the frequency point 2; the mobile terminal searches a cell 2 with the strongest signal under the frequency point 2; the mobile terminal judges whether the searched PLMN of the cell 2 is RPLMN; if the PLMN of the cell 2 is not the RPLMN, determining whether the MCC (460) of the cell 2 is the same as the MCC (100) of the RPLMN; if the MCC (460) of cell 2 is different from the MCC (100) of the RPLMN, the mobile terminal adds one to the number of MCC (460), the number of MCC (460) is 1, and the mobile terminal adds one to the number of MCC (460) to obtain the number of MCC (460) as 2. Since the MCC (460) appears more than the preset number, the mobile terminal searches the PLMN including the MCC (460).
In practical applications, the mobile terminal may be located at a border, and it is not particularly accurate to determine whether the mobile terminal is located in a roaming country through a searched cell, or whether the network currently selected by the mobile terminal is not the network of the country where the mobile terminal is currently located. Therefore, by implementing this embodiment, it can be accurately determined whether the mobile terminal is in a roaming country or whether the network currently selected by the mobile terminal is not the network of the country in which the mobile terminal is currently located.
Further, please refer to fig. 2, wherein fig. 2 is a flowchart illustrating a network searching method according to an embodiment of the present invention. As shown in fig. 2, the network search method may include the following:
201. the mobile terminal selects a first PLMN.
In the embodiment of the invention, the first PLMN is RPLMN.
202. The mobile terminal searches for a cell.
203. The mobile terminal judges whether the PLMN of the first cell is the first PLMN. If the PLMN of the first cell is not the first PLMN, then element 204 is performed.
204. The mobile terminal determines whether the first mobile country code MCC is the same as the second MCC. If the first MCC is not the same as the second MCC, then step 205 is performed. If the first MCC is the same as the second MCC, then step 208 is performed.
In an embodiment of the present invention, the first MCC is an MCC of the first cell, and the second MCC is an MCC in the HPLMN.
In the embodiment of the present invention, the specific implementation of the portions 201 to 204 can refer to the corresponding description of the portions 101 to 104, which is not described herein again.
205. The mobile terminal detects whether the first PLMN has the first MCC. If the first PLMN has the first MCC, then element 206 is performed. If the first PLMN has the first MCC, the network except the first PLMN including the first MCC is searched.
In the embodiment of the present invention, if the first PLMN has the first MCC, the first PLMN currently selected by the mobile terminal is the network of the country where the mobile terminal is currently located. Accordingly, the search for the first PLMN may continue as part 206 may be executed. Because the first PLMN is the RPLMN, the user may power on at the same location after powering off (for example, sleep at night, power on in the next morning), and therefore, the probability of searching for the RPLMN is relatively high, and when the RPLMN is the network of the country where the RPLMN is currently located, the RPLMN can be continuously searched.
206. And the mobile terminal continues to search the first PLMN, and sorts the second PLMN according to a preset rule to obtain a sorting result.
In the embodiment of the present invention, for example, the second PLMNs may be sorted in order of high to low signal quality.
207. And when the first PLMN is not searched, the mobile terminal searches the second PLMN according to the sorting result.
In the embodiment of the invention, when the first PLMN is not searched, the second PLMN is searched according to the sequencing result, which is beneficial to quickly searching a proper network.
208. The mobile terminal detects whether the first PLMN has the first MCC. If the first PLMN does not have the first MCC, then element 209 is performed. If the first PLMN has the first MCC, then part 211 is performed.
In the embodiment of the present invention, if the first MCC and the second MCC are the same and the first PLMN does not have the first MCC, that is, if the first MCC is the same as the MCC in the HPLMN and the first MCC is different from the MCC in the RPLMN, it is indicated that the mobile terminal returns to the home country from the roaming country.
209. The mobile terminal acquires a second PLMN.
In this embodiment of the present invention, the second PLMN is a PLMN recorded with the first MCC and successfully registered for the last time. For example, the home country of the mobile terminal is china, the mobile terminal is powered off before going from china to the united states, and the mobile terminal records that the PLMN used before the power off is the second PLMN. The mobile terminal begins searching for the first PLMN and connects when it arrives in the united states. The mobile terminal returns to China from the United states, the mobile terminal is shut down before returning to China, and the PLMN used before the mobile terminal is shut down is recorded as RPLMN, wherein the RPLMN is the first PLMN. Therefore, the mobile terminal has a greater likelihood of being able to successfully register with the second PLMN after returning to china. It can be seen that by implementing the 208-210 parts, a suitable network can be quickly searched.
210. The mobile terminal searches for a second PLMN.
211. The mobile terminal continues to search for the first PLMN.
Because the first PLMN is the RPLMN, the user may power on at the same location after powering off (for example, sleep at night, power on in the next morning), and therefore, the probability of searching for the RPLMN is relatively high, and when the RPLMN is the network of the country where the RPLMN is currently located, the RPLMN can be continuously searched.
212. And the mobile terminal parks the first cell.
