Of course, the wireless routing device 140 may also include other necessary components, such as a power management chip, a signal amplifier, and the like, and the embodiment of the present application does not limit the specific structure of the wireless routing device 140.
Referring to fig. 3, a schematic structural diagram of a terminal provided in an exemplary embodiment of the present application is shown. The terminal may be implemented as terminal 120 in fig. 1.
Optionally, the terminal 120 includes: a processor 122, a memory 124, and a display 126.

Certainly, the terminal 120 may further include other components such as a distance sensor, a camera, an acceleration sensor, an angular velocity sensor, a positioning module, and a bluetooth module, and the embodiment of the present application does not limit the specific structure of the terminal 120.
Typically, the terminal will maintain several different types of PLMN lists, each including one or more PLMNs. For example, the PLMN list maintained by the terminal may include a Registered PLMN (Registered PLMN, RPLMN) list, an Equivalent PLMN (Equivalent PLMN, EPLMN) list, a Home PLMN (HPLMN) list, and an Equivalent Home PLMN (EHPLMN) list, among others.
During the network searching process, the terminal firstly searches the PLMNs in the maintained PLMN list (for example, according to the order of the RPLMN, EPLMN, HPLMN and EHPLMN lists) in sequence. When none of the PLMNs in the PLMN list are searched, other PLMNs are attempted. After the PLMN search (PLMN selection) is completed, the terminal further performs cell selection, and performs cell registration when the cell meets the residence condition.
However, when the terminal is in the roaming state, the PLMN of the roaming destination is not stored in the PLMN list maintained by the terminal, which results in that it takes a long time for the terminal to search for the PLMN of the roaming destination (the terminal searches based on the locally maintained PLMN list and then tries to search for other PLMNs). And after the PLMN search is completed, cell selection registration is also required, which results in low efficiency of cell registration of the terminal in the roaming state.
In the cell registration method provided by the embodiment of the application, the terminal acquires the cell information of the cell from the wireless routing device through the WiFi connection with the wireless routing device under the condition that the cell registration is not completed, and then performs the cell registration according to the cell information, so that the processes of PLMN search and cell selection are omitted, the efficiency of performing the cell registration by the terminal can be remarkably improved under the roaming state, and the power consumption in the cell registration process is reduced. The following description will be made by using exemplary embodiments.
Referring to fig. 4, a flowchart of a method for cell registration provided in an embodiment of the present application is shown, where the embodiment takes the cell registration method as an example for being used in the wireless routing device 140 shown in fig. 1, and the method includes the following steps:
step 401, establishing a WiFi connection with a first terminal.
When a WiFi connection establishment request sent by a first terminal is received, the wireless routing equipment establishes WiFi connection with the first terminal. After the WiFi connection is established, the first terminal can perform network access.
Optionally, the first terminal establishes a WiFi connection with the first terminal through a WiFi password or a verification code. The embodiment of the present application does not limit the specific way of establishing the WiFi connection.
Step 402, receiving a cell information acquisition request sent by a first terminal through WiFi connection, where the cell information acquisition request is sent by the first terminal when cell registration is not completed.
The method comprises the steps that a first terminal sends a cell information acquisition request to wireless routing equipment through WiFi connection with the wireless routing equipment under the condition that cell registration is not completed (namely cellular network search is not completed), and correspondingly, the wireless routing equipment receives the cell 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 connection with multiple terminals, and receive cell information acquisition requests sent by multiple terminals at the same time.
In a possible implementation manner, the cell information acquisition request is automatically sent when the first terminal detects that cell registration is not completed, or the cell information acquisition request is sent by a manual trigger of a user (for example, by clicking a designated control in a WiFi connection interface).
In the non-roaming state, since the PLMN list maintained by the terminal usually includes the PLMN in which the terminal is currently located (for example, stored in the RPLMN list), the terminal can quickly complete PLMN search and complete cell selection registration. In order to avoid that the terminal in the non-roaming state frequently requests the wireless routing device, which causes excessive processing pressure on the wireless routing device, in a possible implementation manner, the first terminal first detects whether the first terminal is in the roaming state, and sends a cell information acquisition request to the wireless routing device when the first terminal is detected to be in the roaming state.
Optionally, the first terminal detects whether the duration of the flight state (or the time duration of the shutdown state) reaches a time duration threshold, and if the duration of the flight state (or the time duration of the shutdown state) reaches the time duration threshold, the first terminal determines that the first terminal is in the roaming state; and if the time length threshold value is not reached, determining that the mobile terminal is in a non-roaming state. For example, the duration threshold is 3 h.
Of course, the first terminal may also determine whether the first terminal is in the roaming state according to the geographic location information, which is not limited in this application.
Step 403, obtaining target cell information according to the cell information obtaining request, where the target cell information includes cell information of a target cell where the first terminal is currently located.
In a possible implementation manner, the wireless routing device obtains target cell information in real time according to the IP address, or the wireless routing device obtains locally stored target cell information, where the target cell information is reported by a terminal that has completed cell registration and has established WiFi connection with the wireless routing device.
Optionally, the target cell Information includes at least one of PLMN, Radio Access Technology (RAT), frequency band, frequency point, Random Access (Random Access) Information, and System Information (System Information).
Optionally, the target cell information at least includes a PLMN, so that the first terminal skips over a locally maintained PLMN list in the roaming state, and performs PLMN search directly according to the PLMN in the target cell information, thereby improving the efficiency of cell registration.
Step 404, sending target cell information to the first terminal through WiFi connection, where the first terminal is configured to perform cell registration according to the target cell information.
After the wireless routing equipment sends the target cell information to the first terminal, the first terminal performs cell registration according to the target cell information, and therefore the cell registration efficiency in a roaming state is improved.
Optionally, because an intersection exists between cells corresponding to different operators, the target cell information sent by the wireless routing device may include multiple pieces of cell information (corresponding to different operators), and accordingly, the first terminal needs to try cell registration in sequence according to the pieces of cell information, and finally complete cell registration.
To sum up, in the embodiment of the present application, a terminal establishes WiFi connection with a wireless routing device, and sends a cell information acquisition request to the wireless routing device when cell registration is not completed, so as to acquire cell information of a current target cell, and further perform cell registration according to the cell information; when the terminal is in the roaming state, by adopting the cell registration method provided by the embodiment of the application, the terminal can directly perform cell registration according to the acquired cell information without consuming a large amount of time to perform PLMN and cell selection, so that the cell registration efficiency is improved, and the electric quantity consumed in the cell registration process in the roaming state is reduced.
Referring to fig. 5, a flowchart of a method for cell registration provided in another embodiment of the present application is shown, where the embodiment takes the cell registration method as an example for the terminal 120 shown in fig. 1 to describe, the method includes the following steps:
step 501, establishing a WiFi connection with a wireless routing device.
Step 502, if the cell registration is not completed, sending a cell information acquisition request to the wireless routing device through WiFi connection, where the wireless routing device is configured to acquire target cell information according to the cell acquisition request, and the target cell information includes cell information of a target cell where the terminal is currently located.
The method comprises the steps that a terminal sends a cell information acquisition request to wireless routing equipment through WiFi connection with the wireless routing equipment under the condition that cell registration is not completed (namely cellular network search is not completed); if the terminal has completed cell registration, the cell information acquisition request will not be sent.
In a possible implementation manner, the cell information acquisition request is automatically sent when the terminal detects that the cell registration is not completed, or the cell information acquisition request is manually triggered and sent by the user (for example, triggered by clicking a designated control in the WiFi connection interface).
In the non-roaming state, since the PLMN list maintained by the terminal usually includes the PLMN in which the terminal is currently located (for example, stored in the RPLMN list), the terminal can quickly complete PLMN search and complete cell selection registration. In order to avoid that the terminal in the non-roaming state frequently requests the wireless routing device, which causes excessive processing pressure on the wireless routing device, in a possible implementation manner, the terminal first detects whether the terminal is in the roaming state, and when the terminal is detected to be in the roaming state, the terminal sends a cell information acquisition request to the wireless routing device.
Optionally, the terminal detects whether the duration of the flight state (or the time duration of the shutdown state) reaches a time duration threshold, and if the duration of the flight state (or the time duration of the shutdown state) reaches the time duration threshold, the terminal is determined to be in the roaming state; and if the time length threshold value is not reached, determining that the mobile terminal is in a non-roaming state. For example, the duration threshold is 3 h.
Of course, the terminal may also determine whether the terminal is in the 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 acquires target cell information in real time according to the IP address, or the wireless routing device acquires locally stored target cell information, where the target cell information is reported by a terminal that has completed cell registration and has established WiFi connection with the wireless routing device.
And 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 equipment.
And step 504, performing cell registration according to the target cell information.
After receiving the target cell information, the terminal does not perform 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 the present application, a terminal establishes WiFi connection with a wireless routing device, and sends a cell information acquisition request to the wireless routing device when cell registration is not completed, so as to acquire cell information of a current target cell, and further perform cell registration according to the cell information; when the terminal is in the roaming state, by adopting the cell registration method provided by the embodiment of the application, the terminal can directly perform cell registration according to the acquired cell information without consuming a large amount of time to perform PLMN and cell selection, so that the cell registration efficiency is improved, and the electric quantity consumed in the cell registration process in the roaming state is reduced.
An IP Multimedia Subsystem (IMS) is a general network structure that provides Multimedia services over an IP-based network, and can implement interworking between vowifi (voice over wifi) and volte (voice over lte). Since the wireless routing device can access the IMS network through the predetermined interface provided by the IMS, the wireless routing device can acquire cell information of a cell in which the terminal is located by means of the IMS. The following description will be made by using exemplary embodiments.
Referring to fig. 6, a flowchart of a method for cell registration provided in another embodiment of the present application is shown, where the embodiment takes the cell registration method as an example for being used in the wireless routing device 140 shown in fig. 1, and the method includes the following steps:
step 601, sending a cell information reporting request to a second terminal through WiFi connection, where the second terminal establishes WiFi connection with the wireless routing device and completes cell registration.
Since all the terminals establishing WiFi connection with the wireless routing device do not complete cell registration, and the cell information of the registered cell is stored in the terminal that has completed cell registration, the wireless routing device can obtain the cell information of the cell from the terminal that has completed cell registration and established WiFi connection.
In a possible implementation manner, after the wireless routing device establishes WiFi connection with the second terminal, if a cell information acquisition request sent by the second terminal is received within a predetermined time, it is determined that the second terminal does not complete cell registration; if the cell information acquisition request sent by the second terminal is not received within the preset time, the second terminal is determined to finish cell registration, and a cell information reporting request is sent to the second terminal.
And step 602, receiving cell information sent by the second terminal through the WiFi connection.
And after receiving the cell information reporting request, the second terminal acquires the cell information of the current resident cell and sends the cell information to the wireless routing equipment through 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.
Certainly, in other possible embodiments, the second terminal that completes cell registration and establishes WiFi connection with the wireless routing device may also actively report cell information, which is not limited in this embodiment of the present application.
Step 603, sending the cell information to an IMS, where the IMS is configured to perform associated storage on 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 acquired cell information to the IMS. In one possible embodiment, the wireless routing device accesses the IMS over a WiFi interface provided by the IMS.
Optionally, the IMS acquires the cell information reported by the wireless routing device, acquires an IP address when the wireless routing device accesses the IMS, and stores the IP address and the cell information in association with each other. Illustratively, the correspondence between the IP address and the cell information is shown in table one (only the cell information includes the PLMN is taken as an example for explanation).
Watch 1
IP address Cell 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, the IP address of the wireless routing device may change), in order to ensure the accuracy of the correspondence between the IP address and the cell information, when the wireless routing device detects that the IP address changes, the wireless routing device performs the steps of acquiring the cell exit information of the second terminal and reporting the cell information to the IMS, thereby ensuring the accuracy of the information in the IMS.
Step 604, establishing a WiFi connection with the first terminal.
Step 605, receiving 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 is not completed.
The implementation of steps 604 to 605 can refer to steps 401 to 402, which are not described herein again.
Step 606, when receiving the cell information acquisition request, accessing IMS through a predetermined interface.
Optionally, the wireless routing device accesses the IMS over a WiFi interface provided by the IMS.
Step 607, obtaining the target cell information from the IMS according to the IP address, where the IMS stores the corresponding relationship between the IP address and the cell information.
After the steps 601 to 603, the IMS stores the correspondence between the IP address corresponding to the wireless routing device and the cell information, so that the wireless routing device can obtain the corresponding cell information from the IMS according to the current IP address, and determine the cell information as the target cell information.
With reference to the data shown in table one, when the IP address of the wireless routing device is 49.76.220.102, the wireless routing device obtains the target cell information from the IMS according to the IP address, where the target cell information is "PLMN: 46000".
Step 608, sending the target cell information to the first terminal through the WiFi connection, where the first terminal is configured to perform cell registration according to the target cell information.
Optionally, because an intersection exists between cells corresponding to different operators, when target cell information sent by the wireless routing device includes multiple pieces of cell information (corresponding to different operators), the first terminal attempts cell registration according to each piece of cell information, and finally completes cell registration according to one piece of cell information.
In this embodiment, the wireless routing device acquires cell information from a terminal that establishes WiFi connection and completes cell registration, and reports the cell information to the IMS; and when a cell information acquisition request sent by other terminals which do not complete cell registration is subsequently received, acquiring target cell information by accessing the IMS, and feeding the target cell information back to the terminals which do not complete cell registration, thereby improving the cell registration efficiency of the terminals.
In another possible implementation, 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 stores the target cell information, and when subsequently receiving a cell information obtaining request, the wireless routing device directly obtains the locally stored target cell information and sends the target cell information to the first terminal, without using IMS, thereby further improving the efficiency of the terminal in cell registration.
In the above embodiment, the terminal needs to establish WiFi connection with the wireless routing device before acquiring the target cell information. When there are many terminals that do not complete cell registration, the wireless routing device cannot establish WiFi connection with all terminals at the same time, so that some terminals still need to perform PLMN and cell search in a conventional manner. In a possible implementation, on the basis of fig. 4, as shown in fig. 7, step 404 further includes the following steps:
step 405, acquiring the receiving frequency of the cell information acquisition request.
In a possible implementation manner, the wireless routing device obtains the request number of the cell information obtaining requests received within a predetermined time period, and calculates the receiving frequency according to the request number and the predetermined time period.
Illustratively, when the predetermined time period is 1 minute and the number of requests is 10, the wireless routing device calculates the receiving frequency to be 10 times/minute.
In step 406, if the receiving frequency is greater than the frequency threshold, the target cell information is broadcasted through WiFi.
The wireless routing equipment detects whether the receiving frequency of the cell information acquisition request is greater than a frequency threshold, if so, a large number of terminals which do not complete cell registration exist, and target cell information is broadcasted through WiFi; if the number is less than the preset value, the target cell information is still provided for the terminal in a mode of connection first and then transmission.
After the wireless routing equipment broadcasts the target cell information, the terminal located in the coverage range of the WiFi signal can acquire the target cell information from the WiFi broadcast only by starting the WiFi scanning function, and then cell registration is carried out.
In other possible embodiments, in order to ensure that a terminal that does not complete cell registration can establish WiFi connection with a wireless routing device to obtain target cell information, the wireless routing device obtains a current connection number, and broadcasts the target cell information through WiFi when the current connection number is greater than a connection number threshold (for example, 15), thereby avoiding a problem that the terminal cannot obtain cell information because WiFi connection cannot be established.
In order to avoid that the terminal having completed cell registration frequently requests 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 step 402, the following steps are further included.
Step 407, the terminal identifier of the first terminal included in the cell information acquisition request is acquired.
The terminal identifier may be a unique identifier such as a MAC address, a bluetooth address, and an International Mobile Equipment Identity (IMEI) of the terminal. The specific type of the terminal identifier is not limited in this application.
And step 408, acquiring the number of times that the first terminal sends the cell information acquisition request within the preset time according to the terminal identifier.
In one possible implementation, the wireless routing device stores a request table, where the request table includes a cell information acquisition request (including a terminal identifier of a terminal of a request sender) received within a predetermined time period before the current time. After the terminal identifier of the first terminal is acquired, the wireless routing equipment counts the occurrence times of the terminal identifier in the request table, so that the times of sending the cell information acquisition request by the first terminal in a preset time length is determined.
For example, the wireless routing device obtains the number of times that the first terminal sends the cell information obtaining request within a predetermined time (10 minutes) by 2 times.
And 409, if the times are smaller than the time threshold, acquiring the target cell information according to the cell information acquisition request.
If the number of times is smaller than the number threshold, the first terminal is indicated to normally request to acquire the cell information, and the wireless routing equipment executes the step of acquiring the target cell information. The above embodiments may be referred to in the process of acquiring the target cell information by the wireless routing device, and this embodiment is not described herein again.
Step 410, if the number of times is greater than the number threshold, stopping responding to the cell information acquisition request.
If the frequency is greater than the frequency threshold, the first terminal frequently requests to acquire the cell information, and the wireless routing equipment does not respond to the cell information acquisition request any more, so that the hidden danger caused by malicious requests of the terminal is avoided.
For example, when the threshold of the number of times is 1 and the number of times that the first terminal sends the cell information acquisition request is 2 times within a predetermined time period, the wireless routing device stops responding to the cell information acquisition request.
