In the embodiments of the disclosure, a home network refers to a Home Public Land Mobile Network (HPLMN), and a roaming network refers to a roaming public land mobile network.
At step S11, a home network of the terminal and a network mode supported by the terminal are determined.
Here, the terminal may determine the home network and the network mode based on information from a network operator. For example, when the network operator makes a USIM card, a Mobile Country Code (MCC) for a home location of the USIM card can be written into the card. Therefore, the terminal can determine the home network by acquiring the MCC prewritten in the currently used USIM card. The network mode supported by the terminal may include, for example, 2G/3G/4G mode. The terminal may support different technologies based on LTE, GSM, Time Division-Synchronous Code Division Multiple Access (TD-SCDMA), Wideband Code Division Multiple Access (WCDMA), etc.
At step S12, a historical network connection record corresponding to the network mode is acquired, wherein the historical network connection record includes one or more network identities of one or more networks to which the terminal is connected historically.
Here, when the terminal supports multiple network modes, historical network connection records corresponding to the network modes can be acquired in order based on priorities of the network modes supported by the terminal. The network identities may include identities of the network operators and the corresponding network mode. The historical network connection record may also include location information, network speed testing information, or other information for the particular network operator at the particular location.
At step S13, it is determined whether the home network exists in the historical network connection record based on the network identities.
When the terminal supports multiple network modes, it can be determined, in order based on priorities of the network modes supported by the terminal, whether the home network exists among the network identities in the historical network connection record corresponding to each network mode.
At step S14, the terminal connects to a roaming network when the home network does not exist in the historical network connection record.
When the terminal supports multiple network modes, it connects to a roaming network in a case where no home network exists among network identities in any historical network connection record corresponding to any network mode. In addition, during the execution of step S13, if the home network is found, then the terminal directly connects to the home network. The terminal may determine that the home network does not exist when the strength of a received signal from the closest home network base station is below a preset threshold. Alternatively or additionally, the terminal may connect to the roaming network according to user setup in the terminal. For example, when the roaming network at the current location has a better connection than the home network, the terminal may connect to the roaming network.
With the technical solution provided by the present disclosure, it is possible for a terminal to search for its home network based on a historical network connection record of the terminal, and to connect to a roaming network when the home network does not exist in the historical network connection record. As such, there is no need to make a search for network in full band for all modes when a terminal connects to a network. Rather, the terminal can connect to a roaming network as long as the home network is not found among identities of networks historically connected. Thus, the terminal can quickly determine whether the terminal is in a roaming network environment. Furthermore, when the terminal is in the roaming network environment, it can quickly connect to a roaming network so that the time for the terminal to connect to the network is shortened.
In one or more embodiments, a historical network connection record includes a historical frequency point record, and a historical frequency point record includes one or more frequency points at which the terminal historically established connection. That is, the network identities included in the historical network connection record are frequency points. As shown in
At step S21, a home network of the terminal and a network mode supported by the terminal are determined.
At step S22, a historical frequency point record corresponding to the network mode is acquired, wherein the historical frequency point record includes one or more frequency points at which the terminal established connections historically.
At step S23, it is determined whether the home network exists at one of the frequency points at which the terminal established connections historically. If the home network exists at one of the frequency points at which the terminal established connections historically, step S25 is performed. If the home network does not exist at any of the frequency points at which the terminal established connections historically, step S24 is performed.
At step S24, the terminal connects to a roaming network.
At step S25, the terminal connects to the home network. The home network and the roaming network generally are managed by different network operators using different communication resources.
In the present embodiment, the terminal connects to a roaming network as long as the home network is not found at the frequency points at which the terminal established connections historically. As such, there is no need to make a search for networks in full band for all modes when a terminal connects to a network. Rather, it is only necessary to make a search at frequency points at which the terminal established connections historically. Thus, it can be quickly determined whether a terminal is in a roaming network environment. Furthermore, when the terminal is in the roaming network environment, it can quickly connect to a roaming network so that the time for the terminal to connect to the network is shortened.
In one or more embodiments, the above method further includes the following steps: searching for one or more roaming networks at each of the frequency point, while determining whether the home network exists at the frequency point; and storing the roaming networks at the frequency point. In other words, when performing the above step S23, the terminal searches for not only the home network but also roaming networks at frequency points at which the terminal established connections historically, and stores the found roaming networks. If multiple roaming networks are found at the frequency points, the multiple roaming networks are stored as a set to facilitate selection of one of the roaming networks to connect to when the terminal needs to connect to a roaming network. In the present embodiment, by searching for both the home network and roaming networks at frequency points at which the terminal established connections historically, the terminal can get the knowledge of the roaming networks promptly.
For example, network modes supported by the terminal include 2G, 3G and 4G. The 4G is in the highest priority, 3G is ranked the second, and 2G is ranked the last. In this case, when searching for a network, it may be determined whether the terminal is in the home network environment, and the terminal may connect to the network rapidly by the following steps.
Firstly, a search is made to determine whether the home network exists at frequency points at which the terminal established connections historically in 4G mode, and meanwhile roaming networks are searched for at the frequency points. If the home network exists, the terminal connects to the home network. Otherwise, the roaming networks found at the frequency points in 4G mode are stored.
Secondly, a search is made to determine whether the home network exists at frequency points at which the terminal established connections historically in 3G mode, and meanwhile roaming network are searched for at the frequency points. If the home network exists, the terminal connects to the home network. Otherwise, the roaming networks found at the frequency points in 3G mode are stored.
Finally, a search is made to determine whether the home network exists at frequency points at which the terminal established connections historically in 2G mode, and meanwhile roaming networks are searched for at the frequency points. If the home network exists, the terminal connects to the home network. Otherwise, the roaming networks found at the frequency points in 2G mode are stored.
In the present embodiment, if no home network is found at frequency points at which the terminal established connections historically in any of 4G, 3G and 2G modes, one of the roaming networks is selected from all the stored ones for the terminal to connect to.
With the technical solution, the terminal connects to a roaming network as long as the home network does not exist at frequency points at which the terminal established connections historically. As such, there is no need to make a search for networks in full band when a terminal connects to a network. Rather, it is only necessary to make a search at frequency points at which the terminal established connections historically. Therefore, it can be quickly determined whether a terminal is in a roaming network environment. Furthermore, when the terminal is in the roaming network environment, it can quickly connect to a roaming network so that the time for the terminal to connect to the network is shortened.
In one or more embodiments, when no home network exists at any of the frequency points at which the terminal established connections historically in all network modes supported by the terminal, one roaming network may be selected from the stored ones to register the terminal therewith and to connect the terminal thereto. Thus, step S14 may be implemented in two manners as follows.
In a first manner, as shown in
At step S31, a preset roaming network set is acquired when the home network does not exist at any of the frequency points.
Here, the preset roaming network set is a set including multiple roaming networks preset by a user. The multiple roaming networks in the set may be assigned with priorities based on parameters like signal strengths from the roaming networks, home locations, network connection qualities and so on.
At step S32, it is determined whether the roaming networks at the frequency points belong to the preset roaming network set. If the roaming networks at the frequency points belong to the preset roaming network set, step S33 is performed. If the roaming networks at the frequency points do not belong to the preset roaming network set, step S34 is performed.
At step S33, the terminal connects to one of the roaming networks at the frequency points according to a priority order of the roaming networks in the preset roaming network set.
At step S34, the terminal connects to one of the roaming networks at the frequency points, based on signal strengths from the roaming networks.
With the embodiment provided by the first manner, when the roaming networks found belong to the preset roaming network set, it is possible to select one of the roaming networks to connect to according to a priority order of the roaming networks in the preset roaming network set. Also, when the roaming networks found do not belong to the preset roaming network set, it is possible to select one of the roaming networks to connect to, based on signal strengths from the roaming networks. As such, the terminal can connect to the optimal roaming network, so as to improve the quality of the network connection.
In a second manner, the step S14 may be implemented by directly selecting one of the stored roaming networks found at the frequency points at which the terminal established connections historically to connect to, based on signal strengths from the roaming networks, when no home network exists at the frequency points. In this way, it is possible to select one of the roaming networks to connect to, based on signal strengths from the roaming networks. As such, the terminal can connect to the network with the highest signal strength, so as to improve the quality of the network connection.
In one or more embodiments, after the terminal connects to a roaming network, the above method further includes steps S41-S44, as shown in
At step S41, networks are searched for at all frequency points according to a preset condition.
The preset condition may be set as a certain periodicity. For example, a search is made for networks in full band every hour. The preset condition may also be set according to the current geographical location of the terminal. For example, when a change of the current location of the terminal is detected, it can be considered that the preset condition is met, and then a search is made for networks in full band. The terminal may sort the frequency points according to the current geographical location and the location information in the historical frequency point record.
At step S42, it is determined whether the home network exists among the networks at all the frequency points. If the home network exists among the networks at all the frequency points, step S43 is performed. If the home network does not exist at any frequency point, step S44 is performed.
At step S43, the terminal is switched from the currently connected roaming network to the home network.
At step S44, the current network connection is maintained.
In the present embodiment, it is possible for the terminal to continue searching for a home network in full band after connecting to a roaming network, and to establish a connection to the home network upon finding the home network. As such, it is avoided that the roaming network is still used even if the terminal has moved from the roaming network environment to the home network environment, and the terminal's network connection can be switched timely based on the current environment.
In the following, there are described apparatus embodiments of the disclosure which may be used to implement the method embodiments of the disclosure.
The determination module 51 is configured to determine a home network of a terminal and a network mode supported by the terminal.
When an operator products a USIM card, a Mobile Country Code (MCC) for a home location of the USIM card can be written into the card. Therefore, the determination module 51 can determine the home network by acquiring the MCC prewritten in the currently used USIM card. The network mode supported by the terminal is, for example, 2G/3G/4G mode.
The acquisition module 52 is configured to acquire a historical network connection record corresponding to the network mode determined by the determination module 51, wherein the historical network connection record includes one or more network identities of one or more networks to which the terminal is connected historically.
When the terminal supports multiple network modes, the acquisition module 52 can acquire the historical network connection records corresponding to the network modes in order based on priorities of the network modes supported by the terminal.
The first judgment module 53 is configured to determine whether the home network exists in the historical network connection record based on the network identities acquired by the acquisition module 52.
When the terminal supports multiple network modes, first judgment module 53 can determine, in order based on priorities of the network modes supported by the terminal, whether the home network exists among the network identities in the historical network connection record corresponding to each network mode.
The first connection module 54 is configured to connect to a roaming network when the first judgment module 53 determines that the home network does not exist in the historical network connection record.
When the terminal supports multiple network modes, the first connection module 54 connects the terminal to a roaming network in a case where no home network exists in any historical network connection record corresponding to any network mode with regards to network identities. In addition, if the home network is found by the first judgment module 53, then the terminal directly connects to the home network.
With the apparatus provided by the embodiment of the present disclosure, it is possible for a terminal to search for its home network based on a historical network connection record of the terminal, and to connect to a roaming network when the home network does not exist in the historical network connection record. As such, there is no need to make a search for networks in full band for all modes when a terminal connects to a network. Rather, the terminal can connect to a roaming network as long as the home network is not found among identities of networks historically connected. Thus, it can be quickly determined whether a terminal is in a roaming network environment. Furthermore, when the terminal is in the roaming network environment, it can quickly connect to a roaming network so that the time for the terminal to connect to the network is shortened.
In one or more embodiments, as shown in
The first judgment sub-module 531 is configured to, when the historical network connection record includes a historical frequency point record and the historical frequency point record includes one or more frequency points at which the terminal established connections historically, determine whether the home network exists at one of the frequency points.

In the present embodiment, the terminal connected to a roaming network as long as the home network does not exist at any of the frequency points at which the terminal established connections historically. As such, there is no need to make a search for networks in full band for all modes when a terminal connects to a network. Rather, it is only necessary to make a search at frequency points at which the terminal established connections historically. Thus, it can be quickly determined whether a terminal is in a roaming network environment. Furthermore, when the terminal is in the roaming network environment, it can quickly connect to a roaming network so that the time for the terminal to connect to the network is shortened.
In one or more embodiments, as shown in
The first searching module 55 is configured to search for one or more roaming networks at each of the frequency point while determining whether the home network exists at the frequency point.
The storage module 56 is configured to store the roaming networks found at the frequency point by the first searching module 55.
In other words, when searching for the home network at frequency points at which the terminal established connection historically, the first searching module 55 also searches for roaming networks at the frequency points. And the storage module 56 stores the found roaming networks. If multiple roaming networks are found at all the frequency points, the multiple roaming networks may be stored as a set to facilitate selection of one of the roaming networks from the set to connect to when the terminal needs to connect to a roaming network. In the present embodiment, by searching for both the home network and roaming networks at frequency points at which the terminal established connections historically, the terminal can get knowledge of the roaming network promptly.
For example, network modes supported by the terminal include 2G, 3G and 4G. The 4G mode is in the highest priority, 3G is ranked the second, and 2G is ranked the last. In this case, when searching for a network, it may be determined whether the terminal is in the home network environment, and the terminal may connect to the network rapidly by the following steps.
Firstly, a search is made and the first judgment module 53 determines whether the home network exists at frequency points at which the terminal established connections historically in 4G mode. Meanwhile, the first searching module 55 searches for roaming networks at the frequency points. If the home network exists, the terminal connects to the home network. Otherwise, the storage module 56 stores the roaming networks found at the frequency points in 4G mode.
Secondly, a search is made and the first judgment module 53 determines whether the home network exists at frequency points at which the terminal established connections historically in 3G mode. Meanwhile, the first searching module 55 searches for roaming networks at the frequency points. If the home network exists, the terminal connects to the home network. Otherwise, the storage module 56 stores the roaming networks found at the frequency points in 3G mode.
Finally, a search is made and the first judgment module 53 determines whether the home network exists at frequency points at which the terminal established connections historically in 2G mode. Meanwhile, the first searching module 55 searches for roaming networks at the frequency points. If the home network exists, the terminal connects to the home network. Otherwise, the storage module 56 stores the roaming networks found at the frequency points in 2G mode.
In the present embodiment, if no home network is found at frequency points at which the terminal established connections historically in any of 4G, 3G and 2G modes, the first connection module 54 selects one of the roaming networks from all the stored ones for the terminal to connect to.
Thus, the apparatus connects to a roaming network as long as the home network does not exist at frequency points at which the terminal established connections historically. As such, there is no need to make a search for networks in full band when a terminal connects to a network. Rather, it is only necessary to make a search at frequency points at which the terminal established connections historically. Therefore, it can be quickly determined whether a terminal is in a roaming network environment. Furthermore, when the terminal is in the roaming network environment, it can quickly connect to a roaming network so that the time for the terminal to connect to the network is shortened.
