Description

Method, device and computer readable storage medium for searching net

Technical field

The present application relates to, but is not limited to, Internet technologies, and in particular, to a method, apparatus, and computer readable storage medium for finding a network.

Background technique

With the development of communication technologies, more and more modes and frequency bands are supported by mobile terminals. For example, 18 frequency bands such as FDL, TDL, WCDMA, TD-SCDMA, GSM, HRPD, and CDMA1X 7 are commonly used in China. In addition, with the pace of internationalization, operators' roaming tariffs are declining and roaming strategies are constantly changing. In order to better enhance the user experience and improve the utilization of operators' resources, domestic operators have adopted terminal systems and roaming modes. Many requests have also been made.

For example, China Mobile Communications Corporation requires that when the terminal is in China, the mode of operation is TDL+TD-SCDMA+GSM. When roaming abroad, TDL+FDL+WCDMA+GSM is turned on, and then, for example, China Telecom requires domestic use. The mode is TDL+FDL+HRPD+CDMA1X, and TDL+FDL+WCDMA+GSM is enabled in non-Japan and South Korea, and FDL+TDL+WCDMA+HRPD+CDMA1X is required in Japan and South Korea.

Since the mobile terminal needs to perform the mobile terminal system mode switching when moving between the non-roaming area and the roaming area, the current practice of the mobile phone is to switch the mode of the mobile terminal by a timer method. For example, when the terminal goes from a non-roaming country to a roaming country, the network is first searched in a non-roaming mode, and a timer is started. When the timer expires, when there is no domestic network, the roaming mode is enabled, and then the network is searched. Look for the network, after the roaming network is found, the registration process is initiated. For example, the current marvell platform is set to 3 minutes, the MTK platform is set to about 2 minutes, and the Qualcomm platform is set to 10 minutes in the early stage. Later, it was found that the time for roaming under the network was too long to change the timer to 1 minute.

The common practice of the above technical solution is to set a timer. After the timer expires, the mobile terminal performs mode switching, and then performs a network registration network. When the mobile terminal moves between the roaming network and the non-roaming network, the roaming mode can be used to register the network registration by means of a timer. However, this time is generally fixed and rigid. When the time setting is unreasonable, the mobile terminal is in the middle. When the navigation and non-roaming status are switched, the problem of extending the network is raised.

Embodiments of the invention

Embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

The embodiment of the invention provides a method, a device and a computer readable storage medium for finding a network, which realizes a fast switching roaming and non-roaming mode of the terminal device, and accelerates the process of registering the network of the terminal device.

Embodiment 1

As shown in FIG. 1 , an embodiment of the present invention provides a method for searching for a network, which is applied to a terminal device, where the method includes steps S101 to S102:

S101. The terminal device searches for a network according to a predetermined rule after there is no network.

Optionally, after the terminal device does not have a network, searching for the network according to a predetermined rule includes steps S201 to S203:

S201. After the terminal device does not have a network, determine whether the terminal device searches for the network for the first time.

S202. When it is determined that the terminal device is looking for the network for the first time, the network is searched according to the full-standard and full-band supported by the terminal device.

S203. When it is determined that the terminal device is not looking for the network for the first time, the network is searched according to the mode and system that the terminal device starts after the network is successfully found.

It should be noted that the embodiment of the present invention may be that the terminal device finds a network after there is no network in the same country, and may also find a network when switching between the roaming ground and the non-roaming ground. The following scenario can be triggered by triggering the network after the terminal has no network:

1) If the network is lost after the terminal device switches from one country to another, it will trigger the network search and switch between mode and system.

2) The network is lost after the terminal device starts the flight mode. When returning from the flight mode to the normal mode, the network needs to be triggered.

3) When the terminal device enters a bad signal area, such as an elevator or a basement, the network may be lost. When re-entering a good signal area, the network will be triggered.

4) When the terminal device is turned on for the first time, the network will also be triggered.

S102. When the terminal device searches for the network successfully, the system and the mode supported by the terminal device are switched according to the parsed mobile country number MCC.

Optionally, when the terminal device searches for the network successfully, switching the system and mode supported by the terminal device according to the parsed mobile country number MCC includes steps S301-S302:

S301. When the terminal device searches for the network successfully, the terminal device parses the system broadcast message of the searched network, and parses the MCC according to the system broadcast message.

S302. Determine, according to the MCC, a current location of the terminal device, and switch to a current system and a mode corresponding to the current location of the terminal device according to the current location of the terminal device.

For example, according to the MCC, it is judged that the current location of the terminal device is the United States, and the system and mode of the terminal device are switched to the corresponding system and mode of the United States.

Optionally, the method further includes: when it is determined that the terminal device is not searching for the network for the first time, after the terminal device searches for the network according to the mode and the system that is successfully opened after the last time the terminal device finds the network, when the terminal device searches for the network is unsuccessful, If the network is searched again for M times according to the protocol and/or platform policy, the system and the frequency band of the terminal device are continuously searched for the network; or,

It should be noted that M may be a preset maximum number of searches again. For example, the preset M is 4, so that when the terminal device searches for the network unsuccessfully, the network is searched again according to the protocol and/or the platform policy. If the third search network succeeds, the system and the mode supported by the terminal device are switched according to the MCC. . If the search is still unsuccessful for 4 times, the network will no longer be searched according to the protocol and/or platform policy, and all the standards and frequency bands of the terminal device continue to search the network.

Of course, it is also possible to set M to 0. In this case, when the terminal device searches for the network unsuccessfully, it is not necessary to search the network according to the protocol and/or platform policy, but directly open all the standards and frequency bands of the terminal device to continue searching the network.

As shown in FIG. 2, it is a roaming scene graph of the mobile terminal 101 according to an embodiment of the present invention.

The

mobile wireless network

100, 200 may be a TDL network, an FDL network, or the like. The network supports standard 3GPP and 3GPP2 protocol standards, can broadcast system messages, and carries network parameters such as MCC.

The mobile terminal 101 supports multi-mode multi-band, for example, supports TDL, FDL, WCDMA, TD-SCDMA, GSM, or supports multiple modes such as TDL, FDL, WCDMA, TD-SCDMA, GSM, HRPD, CDMA1X. The mobile terminal 101 supports multi-mode switching between a non-roaming network and a roaming network.

The wireless communication network terminal/

wireless transmitting equipment

102, 202, such as a base station, an enhanced base station, etc., can transmit wireless signals to the terminal and receive and resolve signals that the mobile terminal cannot.

In the embodiment of the present invention, when the mobile terminal 101 moves from one wireless network 100 to another wireless network 200, if the network is lost, the mobile terminal 101 re-searches the network, and when searching for the network, attempts to resolve the network network system. The message parses the wireless network parameters such as the MCC, and the mobile terminal determines, according to the value of the wireless network parameter MCC, whether the network environment in which the current terminal is located is a non-roaming network or a non-roaming network, thereby determining the format and mode of the mobile terminal, and further including information such as a frequency band. .

As shown in FIG. 3, the process for the mobile terminal to find a network is as follows, including steps S401 to S412:

S401. The mobile terminal performs scene switching of the roaming ground and the non-roaming ground.

S402 determines whether it is the first time to find the network; if it is the first time to find the network to step S407, if it is not the first time to find the network to step S403.

S403. The mobile terminal searches for the network according to the system and mode that is started after the last successful network search.

For example, RPLMN can be searched according to protocol rules.

S404: Determine whether the search network is successful; if successful, go to step S409; if not, go to step S405:

S405. Perform a search M times repeatedly according to the policy of the mobile terminal itself.

S406. Determine whether the search network is successful; if successful, go to step S409; if not, go to step S407.

S407. The mobile terminal needs to open all the standards and frequency bands supported by the mobile terminal, and perform a full-standard, full-band search network.

S408. Determine whether the search network is successful; if the search network succeeds, go to step S409; if the search network fails, go to step S407.

S409. If the mobile terminal searches for the network and obtains the corresponding cell, attempts to parse the read system message, and obtain parameters such as the system message MCC.

S410. After reading the MCC, determine whether the terminal is roaming according to the MCC.

S411. Switch the system and mode supported by the mobile terminal.

S412: Perform PLMN selection according to the protocol rule, select the cell, and initiate registration to the corresponding network.

In this embodiment, the number of times M can be set by the mobile terminal platform, and the smaller the number of times M is set, the shorter the time for the mobile terminal to start full-band scanning. In the case of international roaming, the mobile terminal performs full-band, full-standard mode. The probability of searching the network will also increase, and the possibility of searching for the network is also greater, and the time for the mobile terminal to switch modes is also shorter.

The number M minimum may be set to 0. When M is set to 0, if it is determined in step S404 that the search network is unsuccessful, step S407 is directly performed without performing step S405 and step S406.

Meanwhile, when the number of times M is set to a positive integer, that is, M is not 0.

For example, when M is set to 4, the mobile terminal can repeatedly search for up to 4 times according to its own policy. In each of the 4 times, it can be judged whether to search for the network every time the search is performed. If the network is searched in the third search, then It is possible to directly proceed to step S409, so that it is not necessary to perform the fourth search again. If the network is not searched for the fourth time, step S407 needs to be performed to start all the systems and the frequency band to continue searching.
