Optionally, before the Beidou network device 200 encrypts the original data, the original data may be compressed first. It can be understood that the packet header may also include a compression indication field. The compression indication field may be used to indicate the type of compression algorithm used by the Beidou network device 200 to compress data. Further optionally, the Beidou network device 200 may compress the original data to obtain compressed data. The Beidou network device 200 may add the above-mentioned compression indication field before the compressed data, and then use a key to encrypt the compressed data with the compression indication field added to obtain encrypted data. It should also be noted that when the value of the encryption indication field is a specified value (for example, 0), it can be used to indicate that the Beidou network device 200 does not encrypt the original data. When the value of the compression indication field is a specified value (for example, 0), it can be used to indicate that the Beidou network device 200 does not compress the original data.

At the MDCP layer, the Beidou network device 200 can obtain the application layer message sent by the APP layer through the interlayer interface, and use the application layer message as an MDCP SDU. The Beidou network device 200 can split the MDCP SDU into one or more fixed-length MDCP segment data (M_segment), and add a follow-up indication field to the header of each MDCP segment data to obtain the MDCP PDU, that is, the MDCP PDU includes M_segment and successor indication fields.

The letter general information includes the name of the contact indicated by the identifiers of other terminals in the query result, and the number of short messages sent by the contact. For example, the query result includes the identifier "13xxxxxxxx9", and the number of messages corresponding to the identifier is 2. If the indicated contact is "Lily", then the information profile information may prompt the user that two letters from the contact "Lily" are waiting to be received.

When the terminal 100 can determine that the application layer message is a download result based on the message type indication field in the received application layer message, the terminal 100 can display the receiving prompt information, and the receiving prompt information can be used to prompt the user to receive the download result in the download result.

For example, the download result includes the identifier "13xxxxxxxx9" and the content of the short message corresponding to the identifier. The contact indicated by the identification is "Lily", then receiving the prompt information may prompt the user that a letter from the contact "Lily" has been received. In some embodiments, the terminal 100 may display the content of the short message in the download result in response to the user's input for receiving the prompt information. Optionally, the receiving prompt information of the terminal 100 may also include the number of short messages sent by the contact.

After the short message center 25 receives the first short message sent to the terminal 100, it can send query information to the home location register/home subscriber server 28. The query information includes the identification of the terminal 100, which can be used to query the location of the terminal 100. network left.

S404, the HLR/HSSR server 28 feeds back to the short message center that the terminal 100 resides in the Beidou network.

The home location register/home subscriber server 28 stores information such as the network where the terminal that has subscribed to the cellular network service resides. After receiving the query information sent by the short message center 25, the home location register/home subscriber server 28 can send the terminal 100 resident network information (for example, resident cellular network, resident Beidou network, etc.).

Here, the HLR/HSS server 28 feeds back to the short message center 25 that the terminal 100 resides in the Beidou network.

S405, the short message center 25 sends the Beidou prompt information to the terminal 300.

When the short message center 25 determines that the receiving device terminal 100 of the first short message is under the Beidou network, it can send the Beidou prompt information to the terminal 300, and the Beidou prompt information can be used to remind the user of the terminal 300 that the first short message is a satellite message .

S406, the terminal 300 sends confirmation information to the short message center 25.

After receiving the Beidou prompt information, the terminal 300 may display the Beidou prompt information. Wherein, the terminal 300 can display the Beidou prompt information in the form of text, picture, voice and so on. For example, the Beidou prompt information displayed by the terminal 300 may be a text type prompt information: "The recipient of the short message you sent is under the Beidou network. Are you sure to send the satellite message?". When the terminal 300 displays the Beidou prompt information, it may also display a confirmation control and a cancel control. Wherein, the confirmation control can be used to trigger the terminal 300 to send confirmation information to the short message center 25 , to instruct the short message center 25 to send the first short message to the terminal 100 . Wherein, the cancel control can be used to trigger the terminal 300 to send cancel information to the short message center 25, and is used to instruct the short message center 25 to cancel sending the first short message. Here, follow-up description will be made with the situation that the terminal 300 sends confirmation information to the short message center 25.

S407, the short message center 25 sends the first short message to the Beidou network device 200.

After receiving the confirmation information, the short message center 25 can send the first short message to the Beidou network device 200 . Wherein, after receiving the first short message, the Beidou network device 200 may store the first short message.

Optionally, the short message center 25 may directly send the first short message to the Beidou network device 200 without sending the Beidou prompt information to the terminal 300 .

S408, the terminal 100 sends a letter request to the Beidou network device 200 .

The terminal 100 may, upon receiving the user's input of downloading the Beidou short message, send a letter request to the Beidou network device 200 in response to the input. Alternatively, the terminal 100 may send a letter request to the Beidou network device 200 at intervals of a preset time (for example, 30 minutes). For example, the user's input for downloading Beidou short messages may be an input for the terminal 100 to receive a Beidou short message function control, or a voice instruction instructing the terminal 100 to download Beidou short messages, and the like.

S409, the Beidou network device 200 sends the first Beidou short message (including the message content of the first short message) to the terminal 100 .

After receiving the letter request from the terminal 100, the Beidou network device 200 may generate a first Beidou short message based on the first short message. Wherein, the first Beidou short message includes the message content input by the user of the terminal 300 , the identification of the terminal 300 and the identification of the terminal 100 in the first short message. Wherein, the Beidou network device 200 may use the message content of the first short message as the original data to obtain the first Beidou short message. For a specific description, please refer to the above-mentioned embodiment in FIG. 2C , which will not be repeated here.

It can be understood that when the terminal 100 sends an overview request to the Beidou network device 200 , the Beidou network device 200 can obtain the query result based on the stored short message sent to the terminal 100 and send it to the terminal 100 .

In a possible implementation, the short message center 25 can store the short message (for example, the first short message) sent to the terminal under the Beidou network, and when the Beidou network device 200 receives the letter request from the terminal 100, it can send The short message center 25 acquires the short message of the terminal 100 and sends it to the terminal 100 . In this way, the storage space of the Beidou network device 200 can be saved. It can be understood that when the terminal 100 sends an overview request to the Beidou network device 200, the Beidou network device 200 can obtain the identification and quantity information of the short message sent to the terminal 100 from the short message 25, obtain the query result, and send it to Terminal 100.

It can be understood that after receiving the first Beidou short message, the terminal 100 may display receiving prompt information, and the receiving prompt information may be used to prompt the user to receive short messages sent to the terminal 100 by other terminals. In some embodiments, the terminal 100 may display the content of the short message in the download result in response to the user's input for receiving the prompt information. Optionally, the receiving prompt information of the terminal 100 may also include the number of short messages sent by the contact. Optionally, the terminal 100 may directly display the name of the contact and the content of the short message sent by the contact.

It should be noted that the first Beidou short message only refers to that the Beidou network device 200 can encapsulate the message content of the short message sent to the terminal 100 by other terminals as a Beidou short message and send it to the terminal 100 after receiving the letter request. , the number of Beidou short messages here is not limited.

In this way, the terminal 100 under the Beidou network can receive short messages sent by other terminals. However, terminal 100 downloaded all the short messages sent by other terminals through letter requests. For some unimportant short messages (for example, advertising short messages, etc.), downloading these unimportant short messages by terminal 100 occupied the transmission capacity of the Beidou communication system. The air interface resource also consumes the power of the terminal 100 .

In a possible implementation, when the terminal 300 opens the message dialog interface displaying the specified contact, it may first send a network status query request to the cellular network device 400, and the network status query request may be used to request the cellular network device 400 to query the The network status of the terminal 100 corresponding to the specified contact. After receiving the network status query request, the cellular network device 400 will send the network status of the terminal 100 to the terminal 300 .

If the terminal 100 is currently residing under the Beidou network, the terminal 300 outputs a network status prompt, which is used to remind the user that the terminal 100 is currently residing under the Beidou network. If the user wants to send a short message to the terminal 100 under the Beidou network through the terminal 300, the user can edit the message content of the first short message on the terminal 300, and trigger the terminal 300 to send the first short message to the cellular network device 400. Short Message Center 25. After receiving the first short message sent by the terminal 300, the short message center 25 may forward the first short message to the Beidou network device 200. After receiving the download request from the terminal 100, the Beidou network device 200 may send the message content of the first short message to the terminal 100.

If the terminal 100 is currently camping on the cellular network, the terminal 300 may not output the above-mentioned network status prompt, or may output prompt information for reminding the user that the terminal 100 is currently under the cellular network. The user can edit the message content of the first short message on the terminal 300 and trigger the terminal 300 to send the first short message to the short message center 25 of the cellular network device 400 . After receiving the first short message sent by the terminal 300, the short message center 25 may send the message content of the first short message to the terminal 100 under the cellular network.

In a possible implementation manner, the terminal 300 may receive the message content of the first short message input by the user after displaying the message dialogue interface of the designated contact. The terminal 300 receives and responds to the user's input of the send control in the message dialogue interface for the designated contact, and may first send a network status query request to the cellular network device 400, and the network status query request can be used to request the cellular network device 400 to query the designated contact. The network status of the terminal 100 corresponding to the person. After receiving the network status query request, the cellular network device 400 will send the network status of the terminal 100 to the terminal 300 .

If the terminal 100 is currently residing under the Beidou network, the terminal 300 displays a network status prompt, Beidou transmission options, cellular transmission options and cancel options. The network status prompt is used to remind the user that the terminal 100 is currently residing under the Beidou network.

If the user wants to send the edited first short message to the terminal 100 under the Beidou network through the terminal 300, the user can select the Beidou sending option to trigger the terminal 300 to send the first short message to the short message center of the cellular network device 400 25, and instruct the short message center 25 to forward the first short message to the Beidou network device 200. After receiving the download request from the terminal 100, the Beidou network device 200 may send the message content of the first short message to the terminal 100.

If the user wants to send the edited first short message to the terminal 100 when the terminal 100 switches back to the cellular network, the user can select the cellular sending option to trigger the terminal 300 to send the first short message to the cellular network device 400 The short message center 25, and instruct the short message center 25 to send the first short message to the terminal 100 when detecting that the terminal 100 switches back to the cellular network.

If the user does not want to send the edited first short message to the terminal 100, the user can select the cancel option to trigger the terminal 300 to cancel sending the first short message to the short message center 25 of the cellular network device 400.

In a possible implementation, after the short message center 25 receives the first short message sent by the terminal 300 and receives the indication information that the terminal 300 does not send the first short message to the terminal 100 through the Beidou network, the short message The center 25 can store the first short message. If the terminal 100 resides on the cellular network before timeout (for example, within 72 hours after the short message center 25 receives the first short message), the short message center 25 can send the first short message to the cellular network. The short message is sent to the terminal 100 under the cellular network. If the terminal 100 has not camped on the cellular network after timeout (for example, 72 hours after the short message center 25 receives the first short message), the short message center 25 can delete the first short message.

An embodiment of the present application provides a method for controlling a whitelist in a Beidou communication system. A white list may be configured in the terminal 100, and the white list includes identifiers of N terminals associated with the terminal 100 and serial numbers of the identifiers in the whitelist. Wherein, the identification of the N terminals may be a user ID (for example, a mobile phone number) of each terminal in the N terminals. The white list configured by the terminal 100 may be stored in the Beidou network device 200 (for example, the Beidou short message integrated communication platform 24 ). When the Beidou network device 200 receives the letter request sent by the terminal 100, it can determine the short message sent by the terminal in the white list based on the stored white list of the terminal 100, and send the short message sent by the terminal in the white list to the terminal 100. In this way, terminal 100 can only receive short messages sent by terminals in the white list. It can be understood that, after receiving the overview request from the terminal 100, the Beidou network device 200 may send a query result to the terminal 100, and the query result includes information on the number of short messages sent to the terminal 100 by terminals in the white list. Optionally, the query result may also include information on the number of short messages sent to the terminal 100 by terminals not in the white list.

Next, a schematic flowchart of a method for controlling a whitelist in a Beidou communication system provided by an embodiment of the present application is introduced.

Exemplarily, as shown in Figure 5B, the method includes:

S501. The terminal 100 reports to reside on the Beidou network.

When the terminal 100 enters the Beidou network, it may report to the cellular network device 400 (for example, the home location register/home subscriber server 28) that it has entered the Beidou network.

S502, the terminal 300 sends the first short message to the short message center 25.

It should be noted that the first short message also includes the identifier of the terminal 300, that is, the user ID.

S503, the short message center 25 queries the home location register/home subscriber server 28 for the network where the terminal 100 resides.

S504, the HLR/HSSR server 28 feeds back to the short message center 25 that the terminal 100 resides in the Beidou network.

S505, the short message center 25 sends the Beidou prompt information to the terminal 300.

S506, the terminal 300 sends confirmation information to the short message center 25.

S507, the short message center 25 sends the first short message to the Beidou network device 200.

S508, the terminal 100 sends a letter request to the Beidou network device 200 .

The terminal 100 may, upon receiving the user's input of downloading the Beidou short message, send a letter request to the Beidou network device 200 in response to the input. Alternatively, the terminal 100 may send a letter request to the Beidou network device 200 at intervals of a preset time (for example, 30 minutes).

Wherein, for the specific description of step S501-step S508, reference may be made to the embodiment shown in FIG. 5A above, and details are not repeated here.

S509, the Beidou network device 200 determines whether the white list of the terminal 100 includes the user ID of the terminal 300.

After the Beidou network device 200 receives the letter request from the terminal 100, it can determine whether the white list includes the user ID of the terminal 300. If the white list includes the user ID of the terminal 300, the Beidou network device 200 can perform step S510; If the user ID of the terminal 300 is not included in the list, the Beidou network device 200 may execute step S511.

It should be noted that the terminal 300 described here is only an example. After the Beidou network device 200 receives the letter request, it will judge whether the short messages sent by all other terminals to the terminal 100 are short messages sent by terminals in the white list. And send all the short messages sent by the terminals in the white list to the terminal 100 .

S510, the Beidou network device 200 sends a first Beidou short message (including message content of the first short message) to the terminal 100 .

S511, the Beidou network device 200 sends a second Beidou short message to the terminal 100.

The Beidou network device 200 determines that the ID number of the terminal 300 is not included in the white list, and the second Beidou short message generated by the Beidou network device 200 does not include the first short message sent by the terminal 300 . Wherein, if the Beidou network device 200 also includes a short message sent to the terminal 100 by a terminal in the white list, the second Beidou short message may include the message content of the short message sent to the terminal 100 by a terminal in the white list. If the Beidou network equipment does not include short messages sent to the terminal 100 by terminals in the white list, the second Beidou short message may be used to indicate that the terminal 100 has no Beidou short message that can be received.

Optionally, after the terminal 100 receives the second Beidou short message indicating that the terminal 100 has no receivable Beidou short message, it can display a no-letter prompt message, and the no-letter prompt message can be used to remind the user that there is no short message sent by other terminals .

In a possible implementation manner, the Beidou network device 200 only stores short messages sent by whitelist users.

In some embodiments, the short message center 25 may forward the short message to the Beidou network device 200 after receiving the short message sent by other terminals to the terminal (such as the terminal 100 ) under the Beidou network. The Beidou network device 200 may determine a whitelist of receivers (such as the terminal 100 ) based on the identifier of the receiver in the short message, and store the short message sent by the terminal indicated by the whitelist. The Beidou network device 200 may reply with confirmation receipt information, and the confirmation reception information may be used to indicate the stored short message. The short message center 25 may delete the short message indicated by the confirmation receipt information.

In some other embodiments, the short message center 25 stores a white list set by each terminal. The short message center 25 may determine a white list of recipients (such as the terminal 100 ) based on the recipient identifier in the short message, and send short messages sent by terminals in the white list to the Beidou network device 200 .

Next, an example of the whitelist provided in the embodiment of this application is introduced.

In a possible implementation manner, the whitelist includes identifiers of N target terminals, and the length of the whitelist bitmap may be Nbit. For example, if the whitelist contains 10 target terminal identifiers, the length of the whitelist bitmap may be 10 bits. In the embodiment of the present application, N is an integer, and the specific value of N is not limited. The following takes N equal to 10 as an example for illustration. Optionally, the whitelist configured by the terminal 100 may also be stored in the server (for example, the short message center 25 shown in FIG. 1 ) of the operator (for example, China Mobile, China Unicom, China Telecom) corresponding to the identity of the terminal 100 In the embodiment of the present application, this is not limited.

Exemplarily, the white list configured in the terminal 100 may be as shown in Table 1 below.

Table 1

As shown in Table 1, the white list configured by the terminal 100 may include identities of 10 target terminals and serial numbers corresponding to the 10 target terminals. It can be understood that the whitelists set by different users may be different. The whitelists shown in Table 3 above are only examples, and this embodiment of the present application does not limit the identifiers and serial numbers of specific terminals in the whitelists.

In a possible implementation manner, the terminal 100 may set/update the whitelist through the network service operator of the cellular network. For example, the terminal 100 can set/update the whitelist in the following ways:

Mode 1: the terminal 100 can set/update the whitelist through SMS.

Specifically, the terminal 100 may receive an input from the user to send a short message for adjusting the whitelist, and in response to the input, send a short message in a specified format to the operator server (referred to as the Beidou operation server) that provides Beidou communication services. The Beidou operation server can store the adjusted white list and send it to the Beidou network device 200 .

Optionally, the Beidou operation server may also send the adjusted white list to the terminal 100, and the terminal 100 stores the adjusted white list.

In some embodiments, the Beidou operation server may be the HLR/HSS server 28 or the short message center 25 mentioned above.

Exemplarily, as shown in FIG. 6A , the terminal 100 displays a desktop 601 . Wherein, the desktop 601 may include a plurality of application icons, for example, an information application icon 602, a dial application icon 603, a Beidou setting application icon 604, and the like. Wherein, the information application icon 602 may be used to trigger the display of an information application interface (for example, the information application interface 610 shown in FIG. 6B below). The dialing application icon 603 may be used to trigger the display of a dialing application interface (for example, the dialing application interface 701 shown in FIG. 7A below). The Beidou setting application icon 604 can be used to trigger the display of the Beidou setting application interface (for example, the Beidou setting application interface 801 shown in FIG. 8A below).

The terminal 100 receives the user's input (for example, click) on the information application icon 602 , and in response to the input, the terminal 100 may display the information application interface 610 as shown in FIG. 6B .

As shown in FIG. 6B, the information application interface 610 may include a new control 611, and the new control 611 may be used to trigger the terminal 100 to display a contact selection interface (for example, the contact selection interface 620 shown in FIG. 6C below). The information application interface 610 can also display historical contact entries, and the historical contact entries can display the information of the historical contacts and the latest message records of the historical contacts, and the historical contact entries can also be used to trigger the terminal 100 to display and The letter editing interface of this historical contact.

The terminal 100 receives the user's input (for example, click) on the new control 611 , and in response to the input, the terminal 100 may display a contact selection interface 620 as shown in FIG. 6C . The contact selection interface 620 may display a contact display area 621 . The contact display area 621 can display a plurality of contact icons, such as a contact icon 621A, and the contact icon can be used to trigger the display of an information editing interface for communication with the contact corresponding to the contact icon (for example, the information shown in FIG. 6D below). editing interface 630). Wherein, the contact person corresponding to the contact icon 621A is an operator (for example, China Mobile, China Unicom, China Telecom) that provides Beidou communication service.

The terminal 100 may receive a user's input (for example, click) on the contact icon 621A, and in response to the input, the terminal 100 may display the information editing interface 630 .

As shown in FIG. 6D , the information editing interface 630 may include, but is not limited to, an editing column 631 , a sending control 632 and the like. Wherein, the editing column 631 can be used to display the content of the text message input by the user. The sending control 632 can be used to trigger the terminal 100 to send the content of the text message displayed in the editing column 631 to the Beidou operation server. The information editing interface 630 can also display a keyboard display area 633, and the keyboard display area 633 can be used to input text message content. Here, the terminal 100 may receive the user's input on the keyboard display area 633, and display the display instruction information (for example, "white list") input by the user in the edit column 631 shown in FIG. 6D. The display instruction information may be used to trigger the Beidou operation server to return the white list information of the terminal 100 .

The terminal 100 may receive user input (for example, click) on the send control 632, and in response to the input, the terminal 100 may display an information box 641 as shown in FIG. 6E. The information box 641 can be used to display the content in the editing column 631 sent by the user.

After receiving the instruction information sent by the terminal 100, the Beidou operator server may send the whitelist information of the terminal 100 to the terminal 100 based on the instruction information. The terminal 100 may display an information box 642 as shown in FIG. 6E. Wherein, the white list information of the terminal 100 is displayed in the information box 642 . Among them, the white list information includes 10 white list quotas, among which the white list No. 1 to No. 9 has been set with the corresponding terminal identification, and the white list No. 10 has not yet set the corresponding terminal identification. Optionally, the terminal ID may be represented by the name of the user corresponding to the terminal ID in the terminal 100, for example, the terminal ID of No. 1 may be represented by "Dad".

The Beidou operator server can also send adjustment prompt information to the terminal 100. The adjustment prompt information can be used to prompt the user of the terminal 100 to adjust the whitelist instruction, wherein the adjustment prompt information can include but not limited to add instructions, delete instructions and replace instruction. That is to say, adjusting the prompt information can prompt the user to add/update terminal IDs in the white list by adding instructions; delete terminal IDs in the white list by deleting commands; replace the serial numbers of two terminal IDs in the white list by replacing commands .

In some embodiments, adjustment prompt information may also be displayed in the information box 642. For example, the terminal 100 may add/update the identifier in the whitelist through a text message in the format of '1+whitelist serial number+to-be-added mobile phone number', and pass ' A text message in the format of 2+whitelist serial number' deletes the identifiers in the whitelist, and a text message in the format of '3+serial number before adjustment+serial number after adjustment' replaces the serial numbers of the two whitelist identifiers. For example, the adjustment prompt information can be: "Add/replace whitelist: please send '1+ whitelist serial number + mobile phone number to be added'; delete whitelist: please send; adjust whitelist order: please send '3+ serial number before adjustment + Adjusted sequence number'."

The terminal 100 may receive the user's input on the keyboard display area 633 , and display an adding instruction in the editing column 651 . The adding instruction may be used to instruct the Beidou operation server to adjust the terminal identifier of the specified serial number in the white list of the terminal 100 . Here, the adding instruction can be: "1+9+13xxxxxxxx9". This adding command can be used to adjust the terminal corresponding to the No. 9 whitelist quota.

The terminal 100 may receive the user's input on the sending control 632 shown in FIG. 6F , and in response to the input, send the adding instruction displayed in the editing column 651 to the Beidou operation server. The terminal 100 may also display an information box 661 shown in FIG. 6G , in which an adding instruction is displayed, and the information box 661 may be used to prompt the user terminal 100 to send the adding instruction to the Beidou operation server.

After receiving the adding instruction, the Beidou operation server may update the white list of the terminal 100 based on the serial number and the terminal identifier in the adding instruction. After the Beidou operation server adjusts the white list of the terminal 100, it may also send adjustment prompt information to the terminal 100. The adjustment prompt information may be used to prompt the user terminal 100 that the whitelist adjustment is completed. The Beidou operation server may also send the adjusted white list of the terminal 100 to the Beidou network device 200 .

The terminal 100 may display the adjustment prompt information. As shown in the information box 662 shown in FIG. 6G , the information box 662 may display the adjustment prompt information received by the terminal 100 . For example, the adjustment prompt information may be "configure the whitelist successfully".

In some embodiments, after receiving the deletion instruction, the Beidou operation server may delete the terminal identifier corresponding to the serial number in the white list of the terminal 100 based on the serial number in the deletion instruction. For example, after receiving the deletion instruction of "2+9", the Beidou operation server may delete the terminal identifier corresponding to No. 9 whitelist in the whitelist of terminal 100 . Optionally, when the terminal 100 inquires about the white list information from the Beidou operation server again, in the white list information received by the terminal 100, the identification corresponding to the No. 9 white list is "unassigned".

In some other embodiments, after receiving the replacement instruction, the Beidou operation server may change the terminal identifiers corresponding to the two serial numbers in the whitelist of the terminal 100 based on the serial numbers in the replacement instruction. For example, after receiving the "3+2+9" replacement instruction, the Beidou operation server can exchange the terminal ID corresponding to No. 2 white list and the terminal ID corresponding to No. 9 white list in the white list of terminal 100 . That is to say, after the Beidou operation server receives the "3+2+9" replacement command, it modifies the terminal ID corresponding to the No. 2 white list to "13xxxxxxxx8", and modifies the terminal ID corresponding to the No. 9 white list to "13xxxxxxxx1" .

In a possible implementation, when the terminal identifier in the adding instruction received by the Beidou operation server already exists in the white list of the terminal 100, the Beidou operation server may send a repeated prompt message to the terminal 100, and the repeated prompt message may remind the user This terminal ID already exists and cannot be added again.

Mode 2: the terminal 100 can set/update the whitelist through the phone.

Exemplarily, when establishing a call connection with the Beidou operation server, the terminal 100 may broadcast prompt information by voice to prompt the user to input corresponding instructions to adjust the white list of the terminal 100 . For example, the terminal 100 may add/update an identifier in the whitelist through an add instruction, delete an identifier in the whitelist through a delete instruction, and exchange identifiers corresponding to two serial numbers in the whitelist through a replace instruction.

Exemplarily, the terminal 100 may receive a user's input on the dialing application icon 603 shown in FIG. 6A , and in response to the input, display a dialing application interface 701 as shown in FIG. 7A . The dialing application interface 701 may include a dialing keypad 702 , which may be used to receive user input, and may also trigger the terminal 100 to display a contact number input by the user through the dialing keypad 702 . The dialing application interface 701 may also include a dialing control 703, and the dialing control 703 may be used to send a call request to an electronic device (for example, a Beidou operation server) corresponding to a designated contact number. The dialing application interface 701 may also display call records between the terminal 100 and other terminals.

The terminal 100 may display contact information 711 as shown in FIG. 7B after receiving the user's input on the dial pad 702 shown in FIG. 7A . Wherein, the contact information 711 may include but not limited to a contact name and a contact number. Here, the contact information 711 includes the customer service number (for example, "1xxxx") of the operator providing the Beidou communication service, and the service name (for example, "Beidou communication").

The terminal 100 may receive the user's input on the dial control 703 shown in FIG. 7B , and in response to the input, send a call request to the Beidou operation server. After receiving the call request from the terminal 100, the Beidou operation server may agree to the request and establish a call connection with the terminal 100.

After the terminal 100 establishes a call connection with the Beidou operation server, a call interface 720 as shown in FIG. 7C may be displayed. A dial pad control 721 may be displayed on the call interface 720 . The dial pad control 721 can be used to trigger the terminal 100 to display the dial pad. Optionally, the call time between the terminal 100 and the Beidou operation server can also be displayed in real time on the call interface 720 .

After the terminal 100 establishes a call connection with the Beidou operation server, the Beidou operation server may send the first voice prompt information to the terminal 100 . The first voice prompt information may be used to remind the user of the service provided by the Beidou operation server. After receiving the first voice prompt information, the terminal 100 may broadcast the first voice prompt information by voice. For example, the first voice prompt information may include: "Please press '9' for setting the white list".

The terminal 100 may receive a user's input on the dial pad control 721, and in response to the input, display a dial pad 731 as shown in FIG. 7D. The terminal 100 may receive the user's input for the key "9" on the dial keypad 731, and in response to the input, display instruction information 741 as shown in FIG. 7E. The content displayed in the instruction information 741 is the content entered by the user through the dial keypad 731 . The terminal 100 may also send the instruction information 741 to the Beidou operation server.

The Beidou operation server may send the second voice instruction to the terminal 100 after receiving the instruction information 741 . Wherein, the second voice instruction may prompt the user to select a way to adjust the whitelist. For example, the second voice command may be: "Press '1' to add or update the whitelist, press '2' to delete the whitelist, and press '3' to change the order of the whitelist". After the Beidou operation server receives the instruction information of adding or updating the whitelist by the terminal 100, it can send to the terminal 100 a voice instruction including how to add or update the terminal identification in the whitelist (that is, the instruction format including the above-mentioned adding instruction voice commands). After the Beidou operation server receives the instruction information of terminal 100 deleting the terminal identifier in the whitelist, it can send to terminal 100 a voice instruction including how to delete the whitelist (that is, a voice instruction including the instruction format of the above-mentioned deletion instruction). After the Beidou operation server receives the instruction information of terminal 100 to replace the whitelist, it can send to terminal 100 a voice instruction including how to replace the terminal identifier in the whitelist (that is, a voice instruction including the instruction format of the above-mentioned replacement instruction).

Optionally, the second voice instruction may also include detailed whitelist information of the terminal 100, for example, a serial number in the whitelist and a corresponding user ID of the terminal. Optionally, the second voice instruction may also include all the places in the whitelist of the terminal 100, for example, the whitelists from serial number 01 to serial number 10 may be changed. The terminal 100 may broadcast the second voice prompt information by voice.

The terminal 100 may receive the user's input for the key "1" on the dial keypad 731, and in response to the input, display instruction information 751 as shown in FIG. 7F. The instruction information 751 includes the content entered by the user through the dial keypad 731 after the terminal 100 broadcasts the second voice instruction, that is, "1". The terminal 100 may also send the instruction information 751 to the Beidou operation server.

The Beidou operation server may send the third voice instruction to the terminal 100 after receiving the instruction information 751 . Wherein, the third voice command may prompt the user to add or update the whitelist (the third voice command includes the format of the adding command). For example, the third voice command can be: "When adding or updating the white list, please first enter the serial number of the adjusted white list, then enter the set mobile phone number, and press the '#' key when the input is complete."

The terminal 100 may receive the user's input on the dial keypad 731, and in response to the input, display instruction information 761 as shown in FIG. 7G. The instruction information 761 includes the content entered by the user through the dial keypad 731 after the terminal 100 broadcasts the third voice instruction, that is, "10xxxxxxxx9#". The terminal 100 may also send the instruction information 761 to the Beidou operation server. Wherein, the instruction information 761 may be used to instruct the Beidou operation server to add or update the terminal identifier of the specified serial number in the white list of the terminal 100 . For example, when the instruction information 751 is: "101xxxxxxxx9#", the Beidou operation server may modify the 10th identifier in the white list to "1xxxxxxxx9".

Optionally, after the Beidou operation server completes adjusting the whitelist of the terminal 100, it may also send a fourth voice prompt message to the terminal 100, and the fourth voice prompt message may be used to prompt the user that the whitelist adjustment is completed.

In some embodiments, the terminal 100 may send the voice instruction input by the user to the Beidou operation server when the call connection is established with the Beidou operation server. The Beidou operation server can adjust the white list of the terminal 100 based on the voice command. For example, the voice command can be: "add the number 13xxxxxxxx9 to the white list".

It can be understood that when the Beidou operation server receives the instruction information for terminal 100 to delete the terminal identification in the whitelist, it can send a voice instruction including how to delete the whitelist to terminal 100, and terminal 100 can delete the specified serial number through the deletion instruction. Terminal ID. When the Beidou operation server receives the instruction information for terminal 100 to replace the whitelist, it can send a voice instruction including how to replace the terminal identifier in the whitelist to terminal 100, and terminal 100 can replace the terminal identifier corresponding to the two specified serial numbers through the replacement instruction .

In a possible implementation, when the terminal identifier in the adding instruction received by the Beidou operation server already exists in the white list of the terminal 100, the Beidou operation server may send a repeated prompt message to the terminal 100, and the repeated prompt message may remind the user This terminal ID already exists and cannot be added again. After receiving the repeated prompt information, the terminal 100 may voice broadcast the repeated prompt information.

Way 3: The terminal 100 can set/update the whitelist through the application program provided by the operator providing the Beidou communication service.

Exemplarily, the terminal 100 may receive a user's input on the Beidou setting application icon 604 shown in FIG. 6A , and in response to the input, display the Beidou setting application interface 801 as shown in FIG. 8A .

As shown in FIG. 8A , the Beidou setting application interface 801 includes multiple functional controls provided by the Beidou setting application (for example, a whitelist setting control 802, a bill query control, etc.), and these multiple functional controls can be used to trigger the terminal 100. Send the command corresponding to the functional control to the Beidou operation server. For example, the bill query control may trigger the terminal 100 to query the Beidou operation server for the bill information of the terminal 100, and the terminal 100 may also receive and display the bill information. The whitelist setting control 802 can be used to trigger the terminal 100 to display a whitelist setting interface, and the whitelist setting interface can be used to adjust the whitelist.

The terminal 100 may receive user input on the whitelist setting control 802, and in response to the input, display a whitelist setting interface 810 as shown in FIG. 8B. The whitelist setting interface 810 may include a whitelist display area. One or more (for example, 10) whitelist entries may be displayed in the whitelist display area. Each whitelist entry may include the serial number of the entry and the user ID of the whitelisted terminal. It should be noted that, when no terminal identifier is set in the whitelist entry, only the serial number in the whitelist is displayed. For example, the whitelist entry 812 may include a serial number 812A and a terminal identification column 812B. The serial number 812A indicates that the sequence of the terminal ID in the white list is the third. A terminal identifier is displayed in the terminal identifier column 812B, which is used to indicate a corresponding terminal. The whitelist entry 813 may include a serial number 813A and a terminal identification column 813B. The sequence number 813A indicates that the sequence of the terminal ID in the white list is the 10th. No terminal identifier is displayed in the terminal identifier column 813B, that is, no corresponding terminal has been configured for the white list quota. Optionally, the whitelist setting interface 810 may also include a save control 815, the save control 815 can be used to save the adjusted white list of the terminal 100, and is also used to send the adjusted white list of the terminal 100 to Beidou operation server.

The terminal 100 may receive the user's input on the terminal identification bar 813B, and display the keyboard display area. The terminal 100 may receive the terminal identifier entered by the user through the keyboard display area, and display the terminal identifier entered by the user in the terminal identifier column 813B. For example, the terminal identification column 813B may display the terminal identification "13xxxxxxxx9" as shown in FIG. 8C. The terminal 100 may send the adjusted white list of the terminal 100 to the Beidou operation server in response to the user's input to the saving control 815 shown in FIG. 8C , and save the adjusted white list.

In a possible implementation manner, after the terminal 100 receives the user's input on the save control 815, it may detect whether the whitelist identifiers in the adjusted whitelist are duplicated. When the terminal 100 detects that the adjusted white list includes repeated terminal identifiers, the terminal 100 may display a duplicate prompt message, which may remind the user that the terminal identifier already exists and that the terminal identifier cannot be added again. When the terminal 100 detects that the adjusted whitelist does not include repeated terminal identifiers, the terminal 100 may send the adjusted whitelist of the terminal 100 to the Beidou operation server, and save the adjusted whitelist.

Of course, the terminal 100 can also set/update the whitelist in other ways (for example, the user can subscribe to the Beidou communication service at the service provider of the operator and set the whitelist). It should be noted that the above method of setting/updating the whitelist is only an example and should not be construed as a specific limitation.

The embodiment of the present application provides another white list control method in the Beidou communication system. A white list may be configured in the terminal 100, and the white list includes identifiers of N terminals associated with the terminal 100 and serial numbers of the identifiers in the whitelist. The white list configured by the terminal 100 may be stored in the Beidou network device 200 (for example, the Beidou short message integrated communication platform 24 ). The Beidou network device 200 may receive the letter request sent by the terminal 100, and the letter request may include a sender ID field (for example, a white name unit map (bitmap) field, a target terminal ID field). The Beidou network device 200 can determine the short message sent by the terminal specified by the terminal 100 based on the stored white list of the terminal 100 and the sender ID field in the letter request, and send the short message sent by the specified terminal to the terminal 100 . In this way, the terminal 100 can download the short message of the specified terminal. It can be understood that the profile request may also include a sender ID field, and the Beidou network device 200 may send a query result to the terminal 100, and the query result includes information on the number of short messages of the terminal indicated by the sender ID field.

Next, an example of the structure of an inbound application layer message provided by the embodiment of the present application is introduced.

Table 2

As shown in Table 2 above, the inbound application layer message of letter request or profile request may include but not limited to business type field, encryption indication field, compression indication field sender ID field, message ID field and so on. It can be understood that the specific fields contained in the summary request/letter request in the embodiment of the present application and the arrangement order of the fields are only examples, which are not limited by the present application. Wherein, the specific description of each field in the inbound application message shown in Table 2 may be shown in Table 3 below. Table 3 exemplarily shows the lengths corresponding to the fields in Table 2 and specific descriptions.

table 3

As shown in Table 3 above, the service type field may be used to indicate that the service type of the inbound application layer message is a mail message download service or a mailbox profile query service. Wherein, the mail message downloading service includes downloading short message services of designated terminals in the white list, downloading short message services of all terminals, and downloading short message services of non-designated terminals in the white list. Mailbox profile inquiry service includes the service of querying the number of short messages of specified terminals in the white list, the service of querying the number of short messages of all terminals, and the service of querying the number of short messages of terminals not in the white list. Wherein, identifiers of terminals in the whitelist exist in the whitelist, and identifiers of terminals not in the whitelist do not exist in the whitelist.

Exemplarily, the length of the service type field may be 3 bits. Wherein, when the service type field is 000, it indicates that the service type of the inbound application layer message is a general data message. It should be noted that when the service type field indicates that the service type of the inbound application layer message is a general data message, each field of the inbound application layer message is different from the above inbound application layer message of the letter request/profile request , for example, includes a text message entered by the user and does not include a message ID field.

When the service type field is 001, it indicates that the service type of the inbound application layer message is the mailbox profile query service, and the inbound application layer message only inquires about the number of short messages sent to the terminal 100 by terminals in the whitelist . When the service type field is 010, it indicates that the service type of the inbound application layer message is the mailbox profile query service in the mailbox service, specifically to query all terminals (including terminals in the white list and terminals not in the white list) to send The number of short messages sent to the terminal 100. When the service type field is 011, it indicates that the service type of the inbound application layer message is a mailbox profile query service, specifically, it may be querying the number of short messages sent to the terminal 100 by a target terminal not in the white list.

When the service type field is 100, it indicates the service type letter message download service (also called letter download service) of the inbound application layer message. information. When the service type field is 101, it indicates that the service type of the inbound application layer message is a letter message download service, specifically, all terminals (including terminals in the whitelist and terminals not in the whitelist) can be downloaded and sent to the terminal user short message. When the service type field is 110, it indicates that the service type of the inbound application layer message is a letter message download service, specifically downloading a short message sent to the terminal user by an individual non-whitelist user.

Wherein, the value 111 of the business type field is a reserved field. Wherein, the mailbox profile query service and the letter message download service may be collectively referred to as the mailbox service.

In a possible implementation manner, the service type of the inbound application layer message includes, but not limited to, a mail message download service and a mailbox profile query service. Wherein, the mail message downloading service includes downloading short message services of terminals in the white list, downloading short message services of all terminals in the white list, and downloading short message services of terminals not specified in the white list. Mailbox profile query service includes the service of querying the number of short messages of specified terminals in the white list, the service of querying the number of short messages of all terminals in the white list, and the service of querying the number of short messages of terminals not in the white list. For example, when the service type field is 010, it indicates that the inbound application layer message is to query the number of short messages sent to the terminal 100 by all terminals in the white list. When the service type field is 101, it indicates that the inbound application layer message is a short message sent to the terminal 100 by all terminals in the download whitelist.

Wherein, the encryption indication field may be used to indicate whether the inbound application layer message is encrypted, and the encryption algorithm used when encrypting the inbound application layer message. The compression indication field may be used to indicate whether the inbound application layer message is encrypted, and the encryption algorithm used when encrypting the inbound application layer message. Wherein, the message ID field may be used to indicate that the terminal 100 has recently successfully received a Beidou short message. Wherein, the length of the message ID field may be 4 bits.

Wherein, the sender ID field may be used to indicate the short message sent to the terminal 100 by the terminal 100 or the terminal identification of the number of short messages. If the terminal (also referred to as the target terminal) specified by the terminal 100 is in the white list configured by the terminal 100, the sender ID field is a white name unit map (bitmap) field, and the white name unit map field is used to indicate the white list of the target terminal serial number. If the target terminal is not in the white list configured by the terminal 100, then the sender ID field is the target terminal identification field, and the target terminal identification field includes the identification of the target terminal (for example, a mobile phone number).

Exemplarily, taking the whitelist shown in Table 1 as an example, the whitelist in the inbound application layer message may be displayed in the form of a whitelist unit map field, as shown in Table 4 or Table 5 below.

Table 4

As shown in Table 4, the length of the whitelist bitmap field may be 10 bits, where the serial number of each target terminal in the whitelist occupies 1 bit. In a possible implementation manner, the serial number of the target terminal whose serial number is 1 in the whitelist may occupy the most significant bit (most significant bit, MSB) in 10 bits, that is, bit9. Then the serial number of the target terminal whose serial number is 10 in the white list can occupy the least significant bit (least significant bit, LSB) in 10 bits, namely bit0. The serial number of the target terminal whose serial number is 2 in the whitelist may occupy bit8 in 10 bits. By analogy, the serial number of the target terminal whose serial number is 8 in the whitelist may occupy bit 2 of the 10 bits. The serial number of the target terminal whose serial number is 9 in the whitelist may occupy bit1 in 10 bits. For example, if the user wants to query the number of letters sent to the terminal 100 by the target terminal whose serial number is 1 in the whitelist, then the value of the whitelist bitmap filled in the sender ID field by the terminal 100 can be "1000000000". It can be understood that when the Beidou network device 200 can determine the serial number of the target terminal according to the field of the white name unit map, and then confirm the identity of the target terminal corresponding to the serial number from the stored white list of the terminal 100 according to the serial number of the target terminal.

table 5

In some embodiments, as shown in Table 5, the serial number of the target terminal whose serial number is 10 in the whitelist may occupy the MSB of 10 bits, that is, bit9. Then the serial number of the target terminal whose serial number is 1 in the white list may occupy the LSB of 10 bits, that is, bit0. The serial number of the target terminal whose serial number is 9 in the white list may occupy bit8 in 10 bits. The serial number of the target terminal whose serial number is 8 in the white list may occupy bit7 in 10 bits. By analogy, the serial number of the target terminal whose serial number is 3 in the whitelist may occupy bit 2 of the 10 bits. The serial number of the target terminal whose serial number is 2 in the whitelist may occupy bit 1 of the 10 bits. For example, if the user wants to query the number of letters sent to the terminal 100 by the target terminal whose sequence number is 1 in the whitelist, then the value of the whitelist bitmap filled in the sender ID field by the terminal 100 can be "0000000001".

Wherein, the target terminal identification field may be used to indicate an identification of a terminal not in the white list. The length of the target terminal identification field may be 44 bits or 34 bits, which is not limited here. For example, when the identification of the target terminal is a mobile phone number, if the mobile phone number of the target terminal is "13xxxxxxxx9" and the target terminal is not in the white list of the terminal 100, then the terminal 100 can encode the mobile phone number "13xxxxxxxx9" of the target terminal Fill in the 44bit binary data into the target terminal identification field. Alternatively, the terminal 100 may also compress and encode the mobile phone number "13xxxxxxxx9" of the target terminal into 34-bit binary data and fill it into the target terminal identification field.

Exemplarily, when the value of the service type field is 000 or 100 as shown in the above Table 3, the sender ID field in the inbound application layer message is a white name unit map field. When the value of the service type field is 010 or 101 as shown in Table 3 above, the sender ID field in the inbound application layer message is the white name unit map field and the target terminal identification field. When the value of the service type field is 011 or 110 as shown in Table 3 above, the sender ID field in the inbound application layer message is the target terminal identification field.

In a possible implementation, when the inbound application layer message is to obtain all short messages or the number of short messages sent to the terminal 100 by other terminals, the inbound application layer message may not include the sender ID field . For example, the value of the service type field is 010 or 101 as shown in Table 3 above, and the inbound application layer message may not include the sender ID field.

It should be noted that the length of the above business type field, the specific value and the corresponding relationship between the business are only examples, and the length of the business type field, the corresponding relationship between the business type and the value of the business type field can also be other forms, for example, business The length of the type can be more or less bits. For example, when the value of the service type field is 000, it can indicate that the service type of the application layer message is to download the short message service of all terminals, etc., the present application This does not constitute a specific limitation.

Based on the above inbound application layer message, in a possible implementation, the terminal 100 can not only set/update the whitelist through the Beidou operation server in the manner described in Table 1 above, but also set/update the whitelist under the Beidou network. list. In this way, under the Beidou network, the terminal 100 can also update/set the white list. For example, the terminal 100 can set/update the whitelist under the Beidou network in the following ways:

Mode 1: Beidou network device 200 may add the identification of the designated terminal to the in the whitelist.

Mode 2: The Beidou network device 200 may add the identification of the terminal under the cellular network to the whitelist when receiving the Beidou short message sent by the terminal 100 to the terminal under the cellular network.

It can be understood that the terminal 100 and the Beidou network device 200 can adjust the stored white list synchronously. Wherein, since the places in the white list are limited, for example, the terminal 100 may replace terminals in the white list through the following method.

(1) The Beidou network device 200 can replace the terminal ID with the highest serial number.

Specifically, the Beidou network device 200 and the terminal 100 can delete the terminal ID with the serial number 0, and move the subsequent terminal IDs forward, that is, write the terminal ID with the serial number 2 into the serial number 1, and then write the terminal ID with the serial number 3 Write the terminal ID of the serial number 2, and so on. For example, when the white list of the terminal 100 is the white list shown in Table 1, if the terminal 100 sends a download request for downloading the short message sent by the target terminal 11 to the Beidou network device 200, since the white list does not include the terminal 11 . The terminal 100 and the Beidou network device 200 can delete the identification of the target terminal 1, move the identifications of other target terminals forward, and then add the identification of the target terminal 11 to the serial number 10.

(2) The Beidou network device 200 can replace the terminal identifier with the last serial number.

Specifically, the Beidou network device 200 and the terminal 100 can delete the terminal ID with the serial number 10, and move the previous terminal ID backward, that is, write the terminal ID with the serial number 9 into the serial number 10, and then write the terminal ID with the serial number 8 Write the terminal ID of the serial number 9, and so on. For example, when the white list of the terminal 100 is the white list shown in Table 1, if the terminal 100 sends a download request for downloading the short message sent by the target terminal 11 to the Beidou network device 200, since the white list does not include the terminal 11 . The terminal 100 and the Beidou network device 200 can delete the identification of the target terminal 10, move the identifications of other target terminals backward, and then add the identification of the target terminal 11 to the sequence number 1.

(3) The Beidou network device 200 can set the last N terminal identifiers in the whitelist to be replaced, where N is a positive integer.

For example, the Beidou network device 200 and the terminal 100 can be set so that the quotas from serial number 8 to serial number 10 in the white list can be replaced, and the remaining quotas remain unchanged. When the Beidou network device 200 and the terminal 100 adjust the whitelist, they can adjust the terminal identifiers from signal 8 to sequence number 10 according to the above-mentioned embodiments (1) and (2). For example, when the white list of the terminal 100 is the white list shown in Table 1, if the terminal 100 sends a download request for downloading the short message sent by the target terminal 11 to the Beidou network device 200, since the white list does not include the terminal 11 . When the terminal 100 and the Beidou network device 200 replace the terminal ID with the highest sequence number, the terminal 100 and the Beidou network device 200 can delete the ID of the target terminal 8, move the IDs of other target terminals forward, and then replace the target terminal The logo of 11 is added to the serial number 10.

It should be noted that, not limited to the above method of setting/updating the whitelist, the Beidou network device 200 and the terminal 100 can also replace the identifier of the target terminal set recently, etc., which is not limited in this embodiment of the present application. In a possible implementation manner, the white list set by the terminal 100 is added with an emergency rescue number by default.

Next, in conjunction with the inbound application layer messages shown in Table 2 above, a schematic flow chart of another whitelist control method in the Beidou communication system provided by the embodiment of the present application is introduced.

Exemplarily, as shown in Figure 9, the method includes:

S901. The terminal 100 reports to reside on the Beidou network.

S902, the terminal 300 sends the first short message to the short message center 25.

S903, the short message center 25 queries the home location register/home subscriber server 28 for the network where the terminal 100 resides.

S904, the HLR/HSSR server 28 feeds back to the short message center 25 that the terminal 100 resides in the Beidou network.

S905, the short message center 25 sends the Beidou prompt information to the terminal 300.

S906, the terminal 300 sends confirmation information to the short message center 25.

S907, the short message center 25 sends the first short message to the Beidou network device 200.

Wherein, for the specific description of step S901-step S907, reference may be made to the above-mentioned embodiment shown in FIG. 5A , which will not be repeated here.

S908, the terminal 100 sends a letter request for downloading short messages of all terminals to the Beidou network device 200.

The terminal 100 may send a letter request to the Beidou network device 200 in response to receiving the user's input of downloading Beidou short messages of all terminals. Wherein, the service type field of the letter request indicates that the service type of the letter request is a short message service for downloading all terminals.

S909, the Beidou network device 200 sends a first Beidou short message to the terminal 100, where the first Beidou short message includes content of the first short message.

Beidou network equipment 200 stores short messages sent by all other terminals to terminals under the Beidou network. The short messages (including the first short message) are sent to the terminal 100 . That is to say, the Beidou network device 200 can generate the first Beidou short message based on the message content of the first short message, and send the first Beidou short message to the terminal 100 .

It can be understood that when Beidou network device 200 receives a letter request from terminal 100 whose service type is a specified terminal in the white list for downloading, if terminal 300 is a designated terminal in the white list of terminal 100, Beidou network device 200 can send the first The short message is sent to the terminal 100; if the terminal 300 is an unspecified terminal in the white list of the terminal 100 (that is, the terminal 300 is a terminal in the white list of the terminal 100, but the white name unit map field in the letter request does not indicate the serial number of the terminal 300 ), the Beidou network device 200 can send the short message of the terminals in the white list specified by the terminal 100 to the terminal 100.

When the service type of the letter request received by the Beidou network device 200 from the terminal 100 is to download a letter request from a terminal not specified in the white list, if the target terminal identification field in the letter request indicates the identity of the terminal 300, the Beidou network device 200 can send the The first short message is sent to the terminal 100.

In a possible implementation, the service type of the letter request sent by the terminal 100 includes downloading the short message service of a specified terminal in the white list, downloading the short message service of all terminals in the white list, and downloading the short message service of a specified terminal not in the white list. message business.

After the Beidou network device 200 receives the letter request from the terminal 100 for downloading the short messages of all terminals in the white list, it can send all the short messages sent by the terminals in the white list to the terminal 100 . For example, when the white list of the terminal 100 includes the identifier (message ID) of the terminal 300 . The Beidou network device 200 may send the first short message to the terminal 100 . Specifically, the Beidou network device 200 may generate the first Beidou short message based on the message content of the first short message, and send the first Beidou short message including the message content of the first short message to the terminal 100 . For another example, when the white list of the terminal 100 does not include the identification (message ID) of the terminal 300 . If the Beidou network device 200 also includes a short message sent to the terminal 100 by a terminal in the white list, the Beidou network device 200 can generate and send a second Beidou short message to the terminal 100, and the second Beidou short message does not include the first short message. The message content of the message.

It can be understood that when the Beidou network device 200 receives the letter message from the terminal 100, the service type is downloading the short message service of the specified terminal in the white list or downloading the short message service of the specified terminal not in the white list, the specific description can refer to the above figure The embodiment shown in 9 will not be repeated here.

In a possible implementation, if the Beidou network device 200 does not receive short messages from one or more terminals (terminals in the whitelist or terminals not in the whitelist) specified by the letter request before receiving the letter request, Beidou The network device 200 may send first indication information to the terminal 100, where the first indication information is used to indicate that the short messages of the one or more terminals are not stored in the Beidou network device 200. It can be understood that the first indication information includes the identifiers of the one or more terminals. Optionally, after receiving the first indication information, the terminal 100 may display no mail prompt information, and the no mail prompt information is used to remind the user that there is no short message from the terminal indicated by the first indication information. Optionally, the Beidou network device 200 may not reply any message to the terminal 100 .

Similarly, the situation that the Beidou network device 200 receives the profile request from the terminal 100 can refer to the above-mentioned embodiment of the letter request shown in FIG. 9 , which will not be repeated here.

In some embodiments, the short message center 25 may forward the short message to the Beidou network device 200 after receiving the short message sent by other terminals to the terminal (such as the terminal 100 ) under the Beidou network. The Beidou network device 200 may determine a whitelist of receivers (such as the terminal 100 ) based on the identifier of the receiver in the short message, and store the short message sent by the terminal indicated by the whitelist. Optionally, the Beidou network device 200 may reply a confirmation receipt message to the short message center 25, and the confirmation reception message may be used to indicate the stored short message.

Wherein, the service type requested by the letter is to download the short message service of all terminals. For example, a letter request with a value of 101 in the business type field. It can be understood that since the Beidou network device 200 only stores short messages sent by terminals in the white list of terminal 100, the letter request to download all terminals is a letter request to download short messages from all terminals in the white list.

S1012, the Beidou network device 200 sends the first Beidou short message to the terminal 100.

After the Beidou network device 200 receives the letter request from the terminal 100 , it can send all the content of the short messages sent by the terminals in the white list to the terminal 100 .

Wherein, the first indication information includes the identifiers of the one or more terminals. It can be understood that when the Beidou network device 200 only stores the short messages of some of the terminals indicated by the letter request, the Beidou network device 200 may send the second Beidou short message and the first indication information to the terminal 100 .

Optionally, after receiving the first indication information, the terminal 100 may display a prompt message of no mail. The no-mail prompt message can be used to prompt the user that there is no short message sent by the no-mail terminal.

In a possible implementation manner, the short message center 25 stores short messages sent to the terminal 100 by other terminals. After receiving the letter request, the Beidou network device 200 obtains the short message from the short message center 25 based on the letter request and the white list. After receiving the profile request, the Beidou network device 200 acquires the quantity information of short messages from the short message center 25 based on the profile request and the white list. For example, when Beidou network device 200 receives a short message from terminal 100 downloading the terminal 10 in the white list, Beidou network device 200 can send the identification of target terminal 10 and the identification of terminal 100 to short message center 25, and short message center 25 is based on the target terminal The identification of 10 sends the short message sent by the target terminal 10 to the terminal 100 to the Beidou network device 200 . The Beidou network device 200 then sends the message content of the short message sent from the target terminal 10 to the terminal 100 to the terminal 100 .

It can be understood that when the Beidou network equipment (for example, Beidou network equipment 200) receives the Beidou short message sent by the third terminal under the Beidou network (for example, terminal 100) to the first terminal under the Beidou network, the Beidou network equipment It may be determined whether the white list of the first terminal includes the identifier of the third terminal. If the white list of the first terminal includes the identifier of the third terminal, the Beidou network equipment can store the Beidou short message. If the white list of the first terminal does not include the identifier of the third terminal, the Beidou network device may send the Beidou short message to the short message center 25 . After the first terminal returns to the cellular network, the short message center 25 can send the Beidou short message to the first terminal. In this way, Beidou network equipment can only store short messages sent by terminals in the white list, saving storage space. Moreover, Beidou network equipment can only send short messages of terminals in the white list to terminals under the Beidou network, saving air interface transmission resources.
