During the network search process, the terminal will first search for PLMNs in the maintained PLMN list (for example, in the order of the RPLMN, EPLMN, HPLMN, and EHPLMN lists) in order. When none of the PLMNs in the PLMN list is found, other PLMNs will be tried. After completing the PLMN search (selecting a PLMN), the terminal further performs cell selection, and performs cell registration when the cell satisfies the residency condition.

However, when the terminal is in the roaming state, the PLMN of the roaming location is not stored in the PLMN list maintained by the terminal, so it takes a long time for the terminal to search for the PLMN of the roaming location (search based on the locally maintained PLMN list first, and then Try searching for other PLMNs). In addition, after the PLMN search is completed, cell selection and registration still needs to be performed, resulting in low efficiency for the terminal in the roaming state to perform cell registration.

However, in the cell registration method provided by the embodiment of the present application, if the cell registration has not been completed, the terminal obtains the cell information of the cell where it is located from the wireless routing device through the WiFi connection with the wireless routing device, and then according to the cell information Cell registration eliminates the process of PLMN search and cell selection, and can significantly improve the efficiency of cell registration for terminals in the roaming state, and reduce power consumption during cell registration. The following uses a schematic embodiment for description.

Please refer to FIG. 4 , which shows a flow chart of a cell registration method provided by an embodiment of the present application. This embodiment uses the cell registration method for the wireless routing device 140 shown in FIG. 1 as an example for illustration. The method Including the following steps:

Step 401, establishing a WiFi connection with a first terminal.

When receiving the WiFi connection establishment request sent by the first terminal, the wireless routing device establishes a WiFi connection with the first terminal. After the WiFi connection is established, the first terminal can access the network.

Optionally, the first terminal establishes a WiFi connection with the first terminal by means of a WiFi password or a verification code. The embodiment of the present application does not limit the specific manner of establishing the WiFi connection.

Step 402: Receive a cell information acquisition request sent by the first terminal through the WiFi connection, where the cell information acquisition request is sent by the first terminal when the cell registration has not been completed.

When the first terminal has not completed the cell registration (that is, the cellular network search has not been completed), the first terminal sends a cell information acquisition request to the wireless routing device through the WiFi connection with the wireless routing device, and the wireless routing device receives the cell information accordingly. An information acquisition request; if the first terminal has completed cell registration, the cell information acquisition request will not be sent.

It should be noted that the wireless routing device may establish WiFi connections with multiple terminals, and simultaneously receive cell information acquisition requests sent by multiple terminals.

In a possible implementation manner, the cell information acquisition request is automatically sent when the first terminal detects that the cell registration has not been completed, or the cell information acquisition request is manually triggered by the user (for example, by clicking the Triggered by the specified control).

In the non-roaming state, since the PLMN list maintained by the terminal usually includes the current PLMN (for example, stored in the RPLMN list), the terminal can quickly complete the PLMN search and complete the cell selection registration. In order to prevent the terminal in the non-roaming state from frequently requesting the wireless routing device, resulting in excessive processing pressure on the wireless routing device, in a possible implementation manner, the first terminal first detects whether it is in the roaming state, and detects that it is in the roaming state. In the state, send a cell information acquisition request to the wireless routing device.

Optionally, the first terminal detects whether the flight state duration (or shutdown time) reaches the duration threshold, and if it reaches the duration threshold, it is determined to be in the roaming state; if it does not reach the duration threshold, it is determined to be in the non-roaming state. For example, the duration threshold is 3 hours.

Of course, the first terminal may also determine whether it is in a roaming state according to the geographic location information, which is not limited in this application.

Step 403: Acquire target cell information according to the cell information acquisition request, where the target cell information includes cell information of the target cell where the first terminal is currently located.

In a possible implementation manner, the wireless routing device obtains the target cell information in real time according to the IP address, or the wireless routing device obtains the locally stored target cell information, wherein the target cell information is registered by a cell that has completed registration and is related to the wireless routing The terminal reports when the device establishes a WiFi connection.

Optionally, the target cell information includes at least one of PLMN, radio access technology (Radio Access technology, RAT), frequency band, frequency point, random access (Random Access) information, and system information (System Information).

Optionally, the target cell information includes at least PLMN, so that the first terminal skips the locally maintained PLMN list in the roaming state, and directly performs PLMN search according to the PLMN in the target cell information, thereby improving the efficiency of cell registration.

In step 404, the target cell information is sent to the first terminal through the WiFi connection, and the first terminal is used to perform cell registration according to the target cell information.

After the wireless routing device sends the target cell information to the first terminal, the first terminal performs cell registration according to the target cell information, thereby improving the efficiency of cell registration in a roaming state.

Optionally, since there is an intersection between cells corresponding to different operators, the target cell information sent by the wireless routing device may contain multiple pieces of cell information (corresponding to different operators), and correspondingly, the first terminal needs to follow the Trial community registration for each piece of community information, and finally complete the community registration.

To sum up, in the embodiment of this application, the terminal establishes a WiFi connection with the wireless routing device, and sends a cell information acquisition request to the wireless routing device when the cell registration has not been completed, so as to obtain the cell information of the current target cell , and then perform cell registration according to the cell information; when the terminal is in a roaming state, using the cell registration method provided in the embodiment of the present application, the terminal can directly perform cell registration according to the obtained cell information without spending a lot of time on PLMN and cell registration. Select, thereby improving the efficiency of cell registration, and reducing the power consumption during the cell registration process in the roaming state.

Please refer to FIG. 5 , which shows a flow chart of a cell registration method provided by another embodiment of the present application. In this embodiment, the cell registration method is used for the terminal 120 shown in FIG. 1 as an example. The method includes Follow the steps below:

Step 501, establish a WiFi connection with a wireless routing device.

Step 502, if the cell registration has not been completed, send a cell information acquisition request to the wireless routing device through the WiFi connection, and the wireless routing device is used to obtain the target cell information according to the cell acquisition request, and the target cell information includes the cell of the target cell where the terminal is currently located information.

When the terminal has not completed the cell registration (that is, the cellular network search has not been completed), the terminal sends a cell information acquisition request to the wireless routing device through the WiFi connection with the wireless routing device; if the terminal has completed the cell registration, it will not send A cell information acquisition request.

In a possible implementation manner, the cell information acquisition request is automatically sent when the terminal detects that the cell registration has not been completed, or the cell information acquisition request is manually triggered by the user (for example, by clicking a specified control in the WiFi connection interface trigger).

In the non-roaming state, since the PLMN list maintained by the terminal usually includes the current PLMN (for example, stored in the RPLMN list), the terminal can quickly complete the PLMN search and complete the cell selection registration. In order to prevent the terminal in the non-roaming state from frequently requesting the wireless routing device, resulting in excessive processing pressure on the wireless routing device, in a possible implementation, the terminal first detects whether it is in the roaming state, and when it detects that it is in the roaming state , sending a cell information acquisition request to the wireless routing device.

Optionally, the terminal detects whether the flight state duration (or power-off time) reaches the duration threshold, and if it reaches the duration threshold, it is determined to be in the roaming state; if it does not reach the duration threshold, it is determined to be in the non-roaming state. For example, the duration threshold is 3 hours.

Of course, the terminal may also determine whether it is in a roaming state according to the geographic location information, which is not limited in this application.

Optionally, after receiving the cell information acquisition request, the wireless routing device obtains the target cell information in real time according to the IP address, or the wireless routing device obtains locally stored target cell information, wherein the target cell information is registered by the cell, and The terminal that establishes a WiFi connection with the wireless routing device reports.

Step 503, receiving the target cell information sent by the wireless routing device through the WiFi connection.

Correspondingly, the terminal receives and analyzes the target cell information sent by the wireless routing device.

Step 504, performing cell registration according to the target cell information.

After receiving the target cell information, the terminal no longer performs PLMN search according to the maintained PLMN list, but directly performs cell registration according to the target cell information, thereby completing the cellular network search.

To sum up, in the embodiment of this application, the terminal establishes a WiFi connection with the wireless routing device, and sends a cell information acquisition request to the wireless routing device when the cell registration has not been completed, so as to obtain the cell information of the current target cell , and then perform cell registration according to the cell information; when the terminal is in a roaming state, using the cell registration method provided in the embodiment of the present application, the terminal can directly perform cell registration according to the obtained cell information without spending a lot of time on PLMN and cell registration. Select, thereby improving the efficiency of cell registration, and reducing the power consumption during the cell registration process in the roaming state.

IP Multimedia Subsystem (IP Multimedia Subsystem, IMS) is a general network structure that provides multimedia services on an IP-based network, and can realize the intercommunication of VoWiFi (Voice over WiFi) and VoLTE (Voice over LTE). Since the wireless routing device can access the IMS network through a predetermined interface provided by the IMS, the wireless routing device can obtain the cell information of the cell where the terminal is located by means of the IMS. The following uses a schematic embodiment for description.

Please refer to FIG. 6 , which shows a method flow chart of a cell registration method provided by another embodiment of the present application. In this embodiment, the cell registration method is used in the wireless routing device 140 shown in FIG. 1 as an example for illustration. The method includes the following steps:

Step 601 , sending a cell information reporting request to a second terminal through a WiFi connection. The second terminal is a terminal that has established a WiFi connection with a wireless routing device and has completed cell registration.

Since not all terminals that have established a WiFi connection with the wireless routing device have completed cell registration, and the cell information of the registered cell is stored in the terminal that has completed the cell registration, the wireless routing device can complete the cell registration and establish a WiFi connection. The terminal obtains the cell information of the cell where it is located.

In a possible implementation manner, after the wireless routing device establishes a WiFi connection with the second terminal, if it receives a cell information acquisition request sent by the second terminal within a predetermined period of time, it determines that the second terminal has not completed cell registration; After receiving the cell information acquisition request sent by the second terminal within the predetermined time period, it is determined that the second terminal has completed the cell registration, and sends a cell information report request to the second terminal.

Step 602, receiving cell information sent by the second terminal through the WiFi connection.

After receiving the cell information reporting request, the second terminal obtains the cell information of the cell where it currently resides, and sends it to the wireless routing device through the WiFi connection.

Optionally, the cell information sent by the second terminal includes: at least one of PLMN, RAT, frequency band, frequency point, random access information, and system information.

Of course, in other possible implementation manners, the second terminal that completes cell registration and establishes a WiFi connection with the wireless routing device may also actively report cell information, which is not limited in this embodiment of the present application.

In step 603, the cell information is sent to the IMS, and the IMS is used to associate and store the IP address of the wireless routing device and the cell information.

Further, the wireless routing device accesses the IMS through a predetermined interface, and reports the obtained cell information to the IMS. In a possible implementation manner, the wireless routing device accesses the IMS through a WiFi interface provided by the IMS.

Optionally, when the IMS obtains the cell information reported by the wireless routing device, it also obtains the IP address when the wireless routing device accesses, and associates and stores the IP address with the cell information. Schematically, the correspondence between the IP address and the cell information is shown in Table 1 (only the cell information includes PLMN as an example for illustration).

Table I

IP address Community information 49.76.220.99 PLMN: 46002, 46000 49.76.220.102 PLMN: 46000 50.76.220.102 PLMN: 46001

Since the IP address of the wireless routing device may change (for example, after the wireless router is restarted, its IP address may change), therefore, in order to ensure the accuracy of the correspondence between the IP address and the cell information, the wireless routing device detects that the IP address has occurred. When changing, the steps of obtaining the information of the second terminal leaving the cell and reporting the cell information to the IMS are performed, so as to ensure the accuracy of the information in the IMS.

Step 604, establishing a WiFi connection with the first terminal.

Step 605: Receive a cell information acquisition request sent by the first terminal through the WiFi connection, where the cell information acquisition request is sent by the first terminal when the cell registration has not been completed.

For the implementation manners of the above steps 604 to 605, reference may be made to steps 401 to 402, which will not be repeated in this embodiment.

Step 606, when receiving the cell information acquisition request, access the IMS through a predetermined interface.

Optionally, the wireless routing device accesses the IMS through the WiFi interface provided by the IMS.

In step 607, the information of the target cell is acquired from the IMS according to the IP address, and the correspondence between the IP address and the cell information is stored in the IMS.

After the above steps 601 to 603, the IMS stores the corresponding relationship between the IP address of the wireless routing device and the cell information, therefore, the wireless routing device can obtain the corresponding cell information from the IMS according to the current IP address, and The cell information is determined as target cell information.

Combined with the data shown in Table 1, when the IP address of the wireless routing device is 49.76.220.102, the wireless routing device obtains the target cell information as "PLMN: 46000" from the IMS according to the IP address.

Step 608: Send the target cell information to the first terminal through the WiFi connection, and the first terminal is used to perform cell registration according to the target cell information.

Optionally, since there is an intersection between cells corresponding to different operators, when the target cell information sent by the wireless routing device contains multiple pieces of cell information (corresponding to different operators), the first terminal according to each piece of cell information Try community registration, and finally complete community registration according to one of the community information.

In this embodiment, the wireless routing device obtains cell information from a terminal that establishes a WiFi connection and completes cell registration, and reports the cell information to the IMS; when subsequently receiving cell information acquisition requests sent by other terminals that have not completed cell registration, That is, the information of the target cell is obtained by accessing the IMS, and the information of the target cell is fed back to the terminal that has not completed the cell registration, thereby improving the efficiency of the cell registration of the terminal.

In another possible implementation manner, when the wireless routing device has a cell information storage function, after obtaining the cell information through the above steps 601 to 602, the wireless routing device determines the cell information as the target cell information, and records the target cell The information is stored, and when subsequently receiving a cell information acquisition request, the wireless routing device directly obtains the locally stored target cell information and sends it to the first terminal without using the IMS, thereby further improving the efficiency of terminal cell registration.

In the above embodiment, the terminal needs to establish a WiFi connection with the wireless routing device before acquiring the information of the target cell. When there are many terminals that have not completed cell registration, the wireless routing device cannot establish WiFi connections with all terminals at the same time, so some terminals still need to use the traditional method to search for PLMN and cell. In a possible implementation manner, on the basis of FIG. 4, as shown in FIG. 7, the following steps are further included after step 404:

Step 405, obtaining the receiving frequency of the cell information obtaining request.

In a possible implementation manner, the wireless routing device obtains the number of cell information acquisition requests received within a predetermined time period, and calculates the receiving frequency according to the number of requests and the predetermined time period.

Schematically, when the predetermined duration is 1 minute and the number of requests is 10, the wireless routing device calculates that the receiving frequency is 10 times/minute.

Step 406, if the receiving frequency is greater than the frequency threshold, broadcast the information of the target cell through WiFi.

The wireless routing device detects whether the receiving frequency of the cell information acquisition request is greater than the frequency threshold. If it is greater than the frequency threshold, it will determine that there are a large number of terminals that have not completed cell registration, and broadcast the target cell information through WiFi; Provide target cell information to the terminal.

After the wireless routing device broadcasts the target cell information, the terminals within the coverage of the WiFi signal only need to turn on the WiFi scanning function to obtain the target cell information from the WiFi broadcast, and then perform cell registration.

In other possible implementation manners, in order to ensure that terminals that have not completed cell registration can establish a WiFi connection with the wireless routing device to obtain target cell information, the wireless routing device obtains the current connection number, and when the current connection number is greater than the connection number threshold (such as 15), the information of the target cell is broadcast through WiFi, so as to avoid the problem that the terminal cannot obtain the cell information because the WiFi connection cannot be established.

In order to prevent terminals that have completed cell registration from frequently requesting the wireless routing device to send cell information, in a possible implementation manner, on the basis of FIG. 4 , as shown in FIG. 8 , after the above step 402, the following steps are further included.

Step 407, acquiring the terminal identifier of the first terminal included in the cell information acquisition request.

Wherein, the terminal identifier may be a unique identifier such as a MAC address, a Bluetooth address, an International Mobile Equipment Identity (International Mobile Equipment Identity, IMEI) of the terminal. This application does not limit the specific types of terminal identifiers.

Step 408: Obtain the number of cell information acquisition requests sent by the first terminal within a predetermined period of time according to the terminal identifier.

In a possible implementation manner, the wireless routing device stores a request table, which includes cell information acquisition requests received within a predetermined time period before the current time (including the terminal identifier of the request sender terminal). After acquiring the terminal identifier of the first terminal, the wireless routing device counts the number of occurrences of the terminal identifier in the request table, so as to determine the number of times the first terminal sends cell information acquisition requests within a predetermined time period.

For example, the wireless routing device acquires the number of times that the first terminal sends the cell information acquisition request twice within a predetermined time period (10 minutes).

Step 409, if the number of times is less than the number of times threshold, acquire the target cell information according to the cell information acquisition request.

If the number of times is less than the number of times threshold, it indicates that the first terminal is normally requesting to obtain cell information, and the wireless routing device executes the step of obtaining target cell information. Wherein, the process for the wireless routing device to obtain the information of the target cell may refer to the foregoing embodiment, and details will not be repeated in this embodiment.

Step 410, if the number of times is greater than the number of times threshold, stop responding to the cell information acquisition request.

If the number of times is greater than the number of times threshold, it indicates that the first terminal frequently requests to obtain cell information, and the wireless routing device will no longer respond to the cell information obtaining request, thereby avoiding hidden dangers caused by malicious requests of terminals.

For example, when the number of times threshold is 1, and the number of times that the first terminal sends the cell information obtaining request is 2 within a predetermined period of time, the wireless routing device stops responding to the cell information obtaining request.
