Background

The Beidou navigation and positioning system is a satellite navigation and positioning system independently developed in China, and can provide radio determination service (RDSS) service for users. The RDSS service may include a beidou short message service. The service form of the Beidou short message is similar to the short message service provided by domestic operators, and the bidirectional short digital message communication is realized between users and between the users and a central control system by mainly utilizing the bidirectional communication function of the Beidou.

At present, the country promotes the Beidou short message to enter common terminal equipment, and the commercial popularization rate of the Beidou short message is improved. Because the charging systems of the Beidou short message and the common short message are different and the communication paths are different, the terminal equipment needs to be switched between the Beidou network and the cellular network. In the switching process of the Beidou network and the cellular network, the network is disconnected for a period of time, and the user experience is poor.

In a first aspect, an embodiment of the present application provides a method for sending a message based on different networks, which is applied to a first electronic device, and includes: if the first condition is satisfied, determining that the current environment covers the cellular mobile communication network, and searching and residing the cellular mobile communication network; responding to the operation that a user inputs first content on a first interface of a first application program and selects to send, and sending a first message based on a cellular mobile communication network, wherein the type of the first message is a mobile short message, and the first message comprises the first content; if the first condition is determined not to be met, determining that the current environment does not cover the cellular mobile communication network, and searching and residing in the Beidou communication network; responding to the operation that a user inputs second content on a first interface of a first application program and selects to send, and sending a second message based on the Beidou communication network, wherein the type of the second message is a Beidou short message, and the second message comprises the second content; wherein the first condition comprises one or more of: the first electronic equipment is in an elevator scene, a ground depot, a tunnel scene or a high-speed rail scene; the current position of the first electronic equipment is covered by a cellular network; a cell in which the first electronic device last resided is located within a cellular network coverage area; the neighboring cell of the cell where the first electronic device resides last time is located in the coverage area of the cellular network; the cell indicated by the cell information received last time by the first electronic equipment is positioned in the coverage area of the cellular network; the first electronic device is in an airplane mode.

Based on the method provided by the embodiment of the application, the Beidou and cellular switching performance can be improved, and the problem of network disconnection during network switching can be avoided as much as possible. Specifically, when the first condition is met, a cellular mobile communication network (which may be referred to as a cellular network for short) can be searched and resided, and a mobile short message is sent based on the cellular network, so that high cost caused by residence in a Beidou network is avoided, and the network residence experience of a user can be improved; when the first condition is not met, the Beidou communication network can be searched quickly and resided (the Beidou network can be called for short) and the Beidou short message is sent based on the Beidou network, so that the emergency contact efficiency of the user is improved, and the power consumption is reduced (the power consumption caused by the fact that the cellular network is searched all the time is avoided).

In one possible implementation, when the first electronic device is camped on a cellular mobile communication network, the method further comprises: the first electronic equipment receives a third message from the second electronic equipment, and the type of the second message is a mobile short message. That is, the first electronic device can not only transmit the mobile short message but also receive the mobile short message when the first electronic device is resident in the cellular mobile communication network.

In one possible implementation manner, when the first electronic device resides in the beidou communication network, the method further includes: the first electronic equipment receives a fourth message from the second electronic equipment, wherein the type of the fourth message is Beidou short message. That is to say, first electronic equipment not only can send big dipper short message, can also receive big dipper short message when residing in big dipper communication network.

In one possible implementation, the method further includes: and receiving the operation that the user starts the authority of receiving and sending the Beidou short message in the second application program. Therefore, after the user starts the Beidou short message receiving and sending authority in the second application program, the Beidou short message can be received and sent.

In one possible implementation, the method further includes: when the first electronic equipment resides in the cellular mobile communication network, if the second condition is determined to be met, judging whether the current environment covers the cellular mobile communication network; wherein the second condition comprises one or more of: a signal quality of a cell in which the first electronic device is camped is below a first threshold; the signal strength of the cell in which the first electronic device resides is below a second threshold; and the packet loss rate of the cell where the first electronic device resides is greater than a third threshold.

Thus, if the second condition is satisfied, the first electronic device may be considered to be currently unable to access the cellular network (e.g., the first electronic device may drop the network), so that it may be determined whether there is a cellular network in the current environment, so as to determine whether to search for the cellular network and re-access the cellular network.

In one possible implementation, if it is determined that the first condition is satisfied, determining that the current environment covers the cellular mobile communication network includes: when the first electronic equipment resides in the Beidou communication network, whether a first condition is met or not is determined based on a preset period, and if the first condition is met, the current environment is judged to cover the cellular mobile communication network. The first electronic equipment periodically judges whether the first condition is met, if the first condition is met, the cellular network is quickly switched to, high cost caused by the fact that the first electronic equipment is resided in the Beidou network is avoided, and the experience of a user in the network can be improved.

In a possible implementation manner, if the first electronic device turns on a Global Navigation Satellite System (GNSS) function, the determining that the current environment covers the cellular mobile communication network includes: the method comprises the steps of collecting GNSS information, wherein the GNSS information indicates the geographic coordinates of the current position of first electronic equipment; determining that the position indicated by the geographic coordinates has cellular network coverage based on a geo-fencing technology; or sending request information to the cloud server and receiving response information sent by the cloud server; the request information includes geographic coordinates, and the response information is used for indicating that the position indicated by the geographic coordinates has cellular network coverage.

In one possible implementation, the first interface includes an input box and a send option; in response to a user entering first content at a first interface of a first application and selecting an operation to send, sending a first message based on a cellular mobile communications network, comprising: responding to the operation that a user inputs first content in an input box and selects a sending option, sending a first message based on a cellular mobile communication network, and displaying the first message and first prompt information on a first interface, wherein the first prompt information is used for prompting that the type of the first message is short message/multimedia message; responding to the operation that a user inputs second content on a first interface of a first application program and selects to send, sending a second message based on the Beidou communication network, and the method comprises the following steps: and responding to the operation that the user inputs the second content in the input box and selects the sending option, sending a second message based on the Beidou communication network, and displaying the second message and second prompt information on the first interface, wherein the second prompt information is used for prompting that the type of the second message is the Beidou short message.

Therefore, when the first electronic device resides in a cellular mobile communication network (which may be referred to as a cellular network for short), the mobile short message can be sent based on the cellular network, thereby avoiding high cost caused by residing in a Beidou network and improving the network residing experience of a user; when the first electronic equipment resides in the Beidou communication network (the Beidou network can be referred to simply), the Beidou short message can be sent based on the Beidou network, the emergency contact efficiency of the user is improved, and the power consumption is reduced (the power consumption caused by the fact that the cellular network is searched all the time is avoided).

In a possible implementation manner, in a case that the first electronic device resides in the cellular mobile communication network, before the first electronic device receives the first content input by the user, the input frame includes third prompt information for prompting the user that the type of the information to be sent is a short message/multimedia message; under the condition that the first electronic device resides in the Beidou communication network, before the first electronic device receives second content input by a user, the input frame comprises fourth prompt information, and the fourth prompt information is used for prompting the user that the type of information to be sent is Beidou short messages. In this way, the user can know the type of information that can be currently transmitted before inputting the first content or the second content, which can improve the user experience.

In one possible implementation, the first interface further includes an identification of a network in which the first electronic device currently resides. In this way, the user can know the type of the currently resident network, and the user experience can be improved.

The beidou system 400 maps the terminal number and the home operator number of the beidou short message and converts the beidou short message into a short message (mobile short message).

5) After receiving the short message, the authentication center 500 determines the operator platform to which the user sending the short message belongs, and forwards the short message to a corresponding operator platform (e.g., operator platform 700).

6) The carrier platform 700 determines a network device (e.g., network device 900) to which a recipient of the short message (e.g., electronic device 1100) currently corresponds and forwards the short message to the network device 900.

Further, the electronic device 1100 may prompt the user that the short message is a beidou short message from the electronic device 100 (corresponding to the user).

Next, taking the example that the electronic device 1100 sends the beidou short message to the electronic device 100, a procedure that the electronic device 100 communicates with the electronic device 1100 through the RDSS domain and the cellular communication domain will be described.

3) The operator platform 700 may send the short message to the authentication center 500 after receiving the short message.

4) The authentication center 500 can send the short message to the beidou system 400 after receiving the short message.

5) After receiving the short message, the beidou system 400 can send the short message to the receiving platform 300.

6) The receiving platform 300 may send the short message to the satellite 200 after receiving the short message.

7) The satellite 200 may send the short message to the electronic device 100 after receiving the short message.

8) The electronic device 100 receives the beidou short message forwarded by the satellite 200, and the content of the beidou short message is the same as that of the short message sent by the electronic device 1100.

Optionally, after receiving the beidou short message forwarded by the satellite 200, the electronic device 100 may prompt the user that the beidou short message comes from the electronic device 1100 (corresponding user). Further, the electronic device 100 may prompt the user that the beidou sms is an sms/mms (i.e., cellular message) from the electronic device 1100 (corresponding user).

For the communication process between the electronic device 100 and the electronic device 1200, reference may be made to the above description, which is not repeated herein.

In addition, if the electronic device 100 makes an emergency call, the national rescue center 1400 may transmit emergency call information to the nearest rescue center according to the location information of the electronic device that made the emergency call. For example, if the electronic device for emergency call is located somewhere in Yunnan, the emergency call information is sent to the emergency center in Yunnan. For another example, if the electronic device for emergency call is located in vietnam, if the emergency center of vietnam and the national emergency center 1400 are networked, the emergency call information may be transmitted to the emergency center of vietnam.

A process of the electronic device 100 communicating with the electronic device 1500 through the RDSS communication domain will be described below by taking the example that the electronic device 100 sends the beidou short message to the electronic device 1500.

1) The electronic device 100 sends the beidou short message to the satellite 200 based on the beidou network.

4) After receiving the beidou short message, the beidou system 400 determines that the receiver (e.g., the electronic device 1500) of the beidou short message is located in the RDSS communication domain, and sends the beidou short message to the receiving platform 300.

5) After receiving the beidou short message, the receiving platform 300 forwards the beidou short message to the satellite 200.

6) After receiving the beidou short message, the satellite 200 may send the beidou short message to a corresponding receiving party (e.g., the electronic device 1500).

At present, the country promotes the Beidou short message to enter common terminal equipment, and the commercial popularization rate of the Beidou short message is improved. Because the charging systems of the Beidou short message and the common short message are different and the communication paths are different, the terminal equipment needs to be switched between the Beidou network and the cellular network. In the switching process of the Beidou network and the cellular network, the network is disconnected for a period of time, and the user experience is not good.

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. In the description of the present application, unless otherwise specified, "at least one" means one or more, "a plurality" means two or more. In addition, in order to facilitate clear description of technical solutions of the embodiments of the present application, in the embodiments of the present application, terms such as "first" and "second" are used to distinguish the same items or similar items having substantially the same functions and actions. Those skilled in the art will appreciate that the terms "first," "second," etc. do not denote any order or quantity, nor do the terms "first," "second," etc. denote any order or importance.

For convenience of understanding, the method for sending messages based on different networks provided by the embodiments of the present application is specifically described below with reference to the accompanying drawings. When messages are sent based on different networks, network switching needs to be performed based on different situations.

As shown in fig. 3, an embodiment of the present application provides a network switching method, including:

301. the electronic device resides in a cellular network.

The cellular network in which the electronic device (e.g., the first electronic device) resides may include global system for mobile communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), New Radio (NR), and the like, which are not limited herein.

Electronic device camping on a cellular network may be understood as electronic device camping on a cell. The electronic device may scan carrier frequencies of all evolved universal terrestrial radio access network (e-utran) bands. At each carrier frequency, the electronic device searches for the cell with the strongest signal quality (referred to as a cell for short). For each cell, the electronic device may select the cell to camp on when the electronic device determines that both the Reference Signal Receiving Power (RSRP) -related measurement (e.g., Srxlev) and the Reference Signal Receiving Quality (RSRQ) -related measurement (e.g., square) are greater than zero.

302. The electronic device determines whether a second condition is satisfied.

Illustratively, the second condition includes one or more of:

1) the signal quality of the cell in which the electronic device resides is below a first threshold;

2) the signal strength of the cell in which the electronic equipment resides is lower than a second threshold;

3) and the packet loss rate of the cell where the electronic equipment resides is greater than a third threshold.

303. If the second condition is met, the electronic equipment judges whether the current environment has a cellular network.

If the second condition is satisfied, it may be considered that the electronic device cannot currently access the cellular network (for example, the electronic device may drop the cellular network), and therefore, it is necessary to determine whether there is a cellular network in the current environment, so as to determine whether to search for the cellular network and to re-access the cellular network.

304. And if the current environment is determined to have the cellular network, searching the cellular network.

If the first condition is met, the electronic equipment determines that the current environment has a cellular network.

Wherein the first condition comprises one or more of:

1) and determining that the electronic equipment is in the elevator scene.

For example, when the electronic device adopts the gravity sensing sensor to detect the movement trend of the mobile terminal in the vertical direction; or, when the electronic device adopts an acceleration sensor to detect the speed/acceleration of the mobile terminal in the vertical direction; or when the electronic equipment determines that the electronic terminal is currently in the elevator scene according to the motion trend in the vertical direction detected by the gravity sensing sensor and the speed/acceleration in the vertical direction detected by the acceleration sensor.

2) And determining that the electronic equipment is in a ground library and tunnel scene.

For example, the electronic device may obtain the current position of the electronic device in real time through a GPS or a beidou system, and if it is determined that the electronic device is currently located in a basement or a tunnel, the electronic device may be considered to be located in a basement or tunnel scene.

3) And determining that the electronic equipment is in a high-speed rail scene.

For example, the moving speed of the electronic device may be determined by GPS, and after the moving speed of the electronic device is determined to be higher than a certain speed for a certain period of time, the electronic device is considered to be in a high-speed rail scene.

Of course, the electronic device may be in other specific scenarios that may cause a network drop, and is not limited to an elevator scenario, a basement, a tunnel, a high-speed rail, and the like.

4) And determining that the current position of the electronic equipment has cellular network coverage.

For example, if the electronic device turns on a GNSS function (e.g., a GPS function or a beidou function), GNSS information may be collected, which may indicate the geographic coordinates of the current location of the electronic device. The electronic device may determine whether the location indicated by the geographic coordinates is covered by a cellular network.

For example, the electronic device can determine whether the location indicated by the geo-coordinates is covered by a cellular network based on geo-fencing techniques. Alternatively, the electronic device may send the geographic coordinates to a cloud server, which may determine whether the location indicated by the geographic coordinates is covered by a cellular network based on big data or general packet data. The big data includes an association relationship between a geographic location and cell information obtained based on data statistics (e.g., collected from a network device side (e.g., a base station), or provided by an operator). For example, the geographic location a may be associated with cell information a, and the cell information a may include information such as surrounding operator frequency band information, cell ID, and signal strength. The total packet data includes an association relationship between cell information and a geographical location collected by the plurality of electronic devices.

5) Determining that a cell in which the electronic device last resided is within a coverage area of a cellular network.

For example, the ID of the cell in which the electronic device last resided may be converted to a geographic coordinate, and it may be determined whether the location indicated by the geographic coordinate has cellular network coverage.

For example, the terminal device may determine whether the location indicated by the geo-coordinates is covered by a cellular network based on geo-fencing techniques. Alternatively, the terminal device may send the geographic coordinates to a cloud server, which may determine whether there is cellular network coverage in the location indicated by the geographic coordinates based on the big data.

And if the position indicated by the geographic coordinate has cellular network coverage, determining that the cell where the electronic equipment is resided last time is located in the cellular network coverage area.

6) And determining that the adjacent cell of the cell where the electronic equipment resides last time is located in the coverage area of the cellular network.

Similarly, the ID of the neighborhood of the cell where the electronic device last resided may be converted into a geographic coordinate, and it may be determined whether the location indicated by the geographic coordinate is covered by the cellular network.

For example, whether the location indicated by the geo-coordinates is covered by a cellular network may be determined based on geo-fencing techniques. Alternatively, the terminal device may send the geographic coordinates to a cloud server, which may determine whether there is cellular network coverage in the location indicated by the geographic coordinates based on the big data.

And if the position indicated by the geographic coordinate is covered by the cellular network, determining that the adjacent cell of the cell where the electronic equipment resides last time is located in the coverage area of the cellular network.

7) And determining that the cell indicated by the cell information received by the electronic equipment last time is positioned in the coverage area of the cellular network.

Similarly, the ID of the cell indicated by the cell information received last time by the electronic device may be converted into a geographic coordinate, and it may be determined whether the location indicated by the geographic coordinate has cellular network coverage. For example, whether the location indicated by the geo-coordinates is covered by a cellular network may be determined based on geo-fencing techniques. Alternatively, the terminal device may send the geographic coordinates to a cloud server, which may determine whether there is cellular network coverage in the location indicated by the geographic coordinates based on the big data.

And if the position indicated by the geographic coordinate has cellular network coverage, determining that the cell indicated by the cell information received by the electronic equipment last time is located in the cellular network coverage area.

8) And determining that the electronic device is in the flight mode.

For example, the flight mode is generally set in a "settings" application, and the electronic device may call the relevant interface of the "settings" application to query whether the electronic device is in the flight mode.

When the first condition is satisfied, the electronic device determines that the current environment has a cellular network and may search for the cellular network.

In one possible design, on the basis of meeting the first condition, if it is determined that the electronic device is outdoors (for example, it is determined that the electronic device is outdoors according to positioning information collected by a GPS or a beidou module), since the beidou network generally exists outdoors, the electronic device may search for the cellular network and the beidou network at the same time, so as to reside in the cellular network and the beidou network at the same time.

305. And if determining that the current environment has no cellular network, searching the Beidou network.

If the first condition is not met, it can be determined that the cellular network does not exist in the current environment, and the electronic equipment searches for the Beidou network.

The first condition may refer to the related description in step 304, which is not described herein again.

It should be noted that step 304 and step 305 are alternatively executed. That is, if step 304 is executed, step 305 may not be executed; alternatively, if step 305 is performed, step 304 may not be performed.

It is understood that if step 304 is performed, step 306 may be further performed.

306. The electronic device determines whether a cellular network is searched.

If the cellular network is searched, the electronic device normally resides in the cellular network.

If the cellular network is not searched, the electronic device continuously searches the cellular network.

It is understood that if step 305 is performed, then steps 307-309 may be further performed.

307. The electronic device determines whether a Beidou network is searched.

308. If the Beidou network is searched, the electronic equipment normally resides in the Beidou network.

If the Beidou network is not searched, the electronic equipment continuously searches the Beidou network.

309. And when the electronic equipment resides in the Beidou network, judging whether a cellular network exists according to a preset rule.

Wherein, the step of judging whether a cellular network exists according to a preset rule can be to periodically judge whether a first condition is met. If the first condition is met, the cellular network is quickly switched to, high cost caused by the fact that the Beidou network is resided is avoided, and the experience of a user in the network can be improved.

It should be noted that, when the electronic device resides in different networks, different mobile message services, voice services, internet access services (internet access) and the like can be performed. Taking mobile message service as an example, when the electronic device resides in a cellular mobile communication network, the electronic device can send or receive mobile short messages (short messages/multimedia messages); when the electronic equipment resides in the Beidou communication network, the Beidou short message can be sent or received.

In the following, taking an example that a user uses an Application (APP) on an electronic device (e.g., a mobile phone) to receive and send a mobile short message (sms/mms) or a beidou short message, a User Interface (UI) related to the embodiment of the present application is introduced.

As shown in fig. 4 (a), assuming that the user is located in a subway, the mobile phone of the user may search for a cellular network (e.g., a 5G network), and the user may send the sms/mms based on the cellular network. As shown in fig. 4 (b), after the user opens the "information" App, the mobile phone may display an information interface 401, and in the information interface 401, a short message "camp road message" from the contact "mom" may be displayed, and a message "402 is sent to me", because the user is located in the subway, the mobile phone of the user may search for a cellular network (e.g., a 5G network), the information interface 401 may include an icon 403 that is successful in connecting to the 5G network, and an input box 404 in the information interface 401 may prompt that the user may currently send a short message/multimedia message. The user can reply a short message to the contact ' mom ' through ' haha ' based on the 5G network, and has no problem ' 405. Optionally, the mobile phone may display a prompt message 406 above the short message 405 to prompt the user that the short message/multimedia message is currently sent. Optionally, the prompt message 406 may include the sending time of the short message 405 "9:30 am today".

As shown in fig. 5 (a), assuming that a user is located in a field area without cellular network coverage, the mobile phone of the user cannot search for a cellular network (e.g., a 5G network), but can search for a beidou network, and the user can send a beidou short message based on the beidou network. As shown in fig. 5 (b), since the user is located in a field area without cellular network coverage and the cellular network (e.g., 5G network) cannot be searched by the user's handset, the information interface 401 may include an icon 410 of a failure to connect to the 5G network. Since the phone may search for the beidou network, optionally, the information interface 401 may include an icon "BDS" 411 representing the beidou network. Optionally, the beidou network may be represented by other types of identifiers, for example, by the words "beidou" or icons in other shapes, which is not limited in this application. An input box 404 in the information interface 401 may prompt the user that the beidou short message may be currently sent. Optionally, the information interface 401 may further include a prompt message 412, and the prompt message 412 may prompt the user that "the beidou network is currently switched to". Optionally, the prompt message 412 may further include a time for switching to the beidou network.

As shown in (b) in fig. 5, in response to the operation of clicking the input box 404 by the user, as shown in (a) in fig. 6, the mobile phone may display a soft keyboard 421, and the user may input the content of the beidou short message to be sent through the soft keyboard 421. Optionally, the mobile phone may further display a prompt message 422 to prompt the user that the beidou short message is currently being edited. As shown in fig. 6 (b), the user can reply with a beidou short message to the contact "mom" based on the beidou network "we arrive at the destination, here, the starry sky is beautiful" 423.

Optionally, the text color, the text box shape, the text box background color, the pattern and the like of the beidou short message 423 may be different from the text color, the text box shape, the text box background color, the pattern and the like of the short message 405 to prompt the user to send messages in different forms, so that the user can more quickly and quickly identify whether the sent message is a beidou short message or a short message.

In some embodiments, after the user moves from an area without cellular network coverage to an area with cellular network coverage, the handset may re-search for a cellular network and the handset may re-camp on the cellular network. As shown in fig. 7, the next day at 8:00 am, the user may send a short message "we have returned" 430 based on the cellular network.

In other embodiments, when the user is located in an area covered by both the cellular network and the beidou network, the mobile phone can be simultaneously resident in the cellular network and the beidou network, and the user can select to send the short message/multimedia message based on the cellular network and also select to send the beidou short message based on the beidou network. As shown in (a) or (b) of fig. 8, the information interface 401 may simultaneously display an icon 440 of successful connection to the 5G network and an icon "BDS" 441 of the beidou network. As shown in fig. 8 (a), an input box 442 in the information interface 401 may prompt the user that the sms/mms can be currently sent. The user may send a short message "we have returned" 443. The information interface 401 may further include a control 444, and the control 444 may be used to switch the sms/mms and the beidou sms. In response to the user clicking the control 444, the prompt message in the input box 442 may be switched from "sms/mms to beidou sms". The user may send a beidou short message "we have returned" 445.

In a possible design, the user can receive and transmit the Beidou short message in the information APP after the mobile phone starts the Beidou short message receiving and transmitting authority (namely, the function of receiving and transmitting the Beidou short message is started). For example, as shown in (a) in fig. 9, in response to an operation of clicking a "setting" application 902 on a main interface 901 by a user, as shown in (b) in fig. 9, the mobile phone may display a setting interface 903, the setting interface 903 may include a further function option 904, in response to an operation of clicking the further function option 904 by the user, as shown in (c) in fig. 9, the mobile phone may display a further function interface 905, the further function interface 905 may include a function option 906 for transceiving a beidou short message, and if the function for transceiving the beidou short message is turned on, the user may transceive the beidou short message in the information APP.

Optionally, if the mobile phone has sufficient power (for example, the power is greater than or equal to 50%) and is not in the power saving mode, the mobile phone may reside in the cellular network and the beidou network at the same time. In this way, the user can flexibly select a network for communication. If the mobile phone has insufficient power (for example, the power is less than 50%) or the mobile phone is in a power saving mode, the mobile phone can reside in the cellular network in an area simultaneously covered by the cellular network and the Beidou network, so that high cost and power consumption of the mobile phone residing in the Beidou network can be reduced.

When the user resides in the cellular network and the beidou network at the same time, if the cellular network cannot be accessed subsequently, the cellular network may be re-searched based on the methods shown in steps 302 to 304, which are not described herein again.

Based on the method provided by the embodiment of the application, the Beidou and cellular switching performance can be improved. A location with a cellular network may quickly register with the cell reducing the necessary cost and user experience of camping on the network. The Beidou network can be switched rapidly at the position without the cellular network, so that the emergency contact efficiency of the user is improved, and the power consumption is reduced. And the resident network has explicit prompt, so that the user can know the difference between the resident network and the sent information, and the use experience of the user can be improved.
