Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth such as the particular system architecture, techniques, etc., in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
In the embodiment of the application, the unified use of the short message refers to the short message sent by the terminal (or other electronic equipment) through the short message satellite using the short message service, and the unified use of the short message refers to the short message sent by the terminal (or other electronic equipment) through the base station and/or other non-satellite communication network and network elements of the non-GNSS domain using the short message service. In the embodiment of the application, the term "message" is used as a short message and a short message is commonly referred to.
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings.
First, a manner in which a terminal performs short message communication in a cellular communication domain will be described with reference to fig. 1. As shown in fig. 1, the terminal 100 is in a cellular communication domain, i.e. the location of the terminal 100 is covered by a cellular network (or "mobile network"). At this time, the short message (short message service, SMS) transmission and reception of the terminal 100 may be performed through a cellular network. The short message sent by the terminal 100 is sent to the short message center 102 through the base station 101, and the short message center 102 matches the corresponding short message receiver according to the receiver in the short message, and then sends the short message to the receiver terminal 104 through the base station 103. If the short message receiving terminal 104 is in a state where it cannot receive a short message, for example, in an area without coverage of a cellular network or in a power-off state, the short message may be temporarily stored by the short message center 102 until the receiving terminal 104 is in a state where it can receive a short message again, for example, returns to an area covered by a cellular network or is powered on, at which time the short message center 102 sends the short message to the receiving terminal 104. Accordingly, the process of sending a short message by the terminal 104 and receiving a short message by the terminal 100 may be performed in a similar manner in the cellular communication domain.
The process of the short message center 102 sending the short message to the 104 receiving party terminal 104 via the base station 103 is usually actively initiated by the short message center 102. Specifically, if the terminal 104 is in a state capable of receiving a short message, the short message center 102 sends the short message to the base station 103 of the cellular communication cell where the receiving terminal 104 is located, and then the base station 103 sends the short message to the terminal 104; if the terminal 104 is in a state of not receiving the short message, the short message center 102 temporarily stores the short message until the terminal 104 is in a state of receiving the short message again. The short message service in the cellular communication domain is usually that the sender user pays the fee for sending the short message, and the short message receiver user receives the short message without paying the fee, so the way that the short message center 102 actively sends the short message to the receiver terminal is generally acceptable to the user.
A terminal adopting a cellular network for short message communication can communicate with a base station only when the terminal is positioned in the signal receiving and transmitting range of the base station, namely the coverage area of the cellular network, otherwise, the terminal cannot receive and transmit the short message. The signal coverage of each base station is often relatively limited, e.g., a radius ranging from several hundred meters to tens of kilometers. In some sparsely populated remote areas there may be no coverage of the base station or the base station may be destroyed after a natural disaster such that the cellular communication network is paralyzed, resulting in blocked short message transmissions through the cellular communication network.
Next, a manner in which the terminal in the GNSS domain performs short message communication in the GNSS domain will be described with reference to fig. 2. GNSS, known collectively as global navigation satellite systems (global navigation satellite system, GNSS), currently include the global positioning system (global positioning system, GPS), the beidou satellite navigation system (beidou navigation satellite system, BDS), the GLONASS satellite navigation system (GLONASS), and the GALILEO satellite navigation system (GALILEO). Three geosynchronous orbit (geostationary orbit, GEO) satellites in the beidou satellite navigation system can perform two-way communication with ground equipment (such as terminals, radars, ground stations and the like). These three satellites are generally called as Beidou short message satellite or short message satellite 201, and can be matched with ground station 202 and short message server 203 to provide short message service for ground terminals, and the messages sent by the terminals through the short message service can be called as Beidou short messages or short messages.
The process of the terminal 200 in the GNSS domain sending a short message to the terminal 204 is as follows: first, the terminal 200 sends a short message to the short message satellite 201, and then the short message satellite 201 sends the short message to the short message server 203 for storage via the ground station 202. When the terminal 204 transmits a short message reception request to the short message satellite 201, the short message satellite 201 transmits the request to the short message server 203 via the ground station 202. In response to the request, the short message server 203 retrieves the short message with the recipient as the terminal 204 from the storage space of the short message server 203, then sends the short message with the recipient as the terminal 204 to the short message satellite 201 through the ground station 202, and finally sends the short message to the terminal 204 by the short message satellite 201. Accordingly, the process of the terminal 204 sending short messages to the terminal 200 may also be accomplished in a similar manner in the GNSS domain.
The short message service is different from the short message service in the cellular communication domain in terms of cost in that the terminal needs to pay the cost both for sending and receiving the short message. Therefore, the short message service generally does not adopt a manner that the short message server 203 actively transmits the short message to the receiving terminal, but transmits the short message to the receiving terminal after the short message server 203 receives the short message receiving request transmitted by the receiving terminal.
The wide communication coverage of the short message satellite 201 makes the short message service almost unlimited by regions, and does not need to rely on a large number of base stations located on the ground to realize the wide communication coverage. Thus, a user can communicate through a short message service when no cellular communication network is available, such as when the user is located in an area of the ocean, desert, etc. where no base station is covered, or when a base station is destroyed after a natural disaster. For example, the short message server 203 may communicate with the emergency rescue platform 205 so that short messages such as disaster situations or rescue requests may be sent to the emergency rescue center 206 in time when, for example, a base station is destroyed after a natural disaster, fishermen are trapped in the ocean without a nearby base station, etc.; alternatively, two terminals (e.g., terminal 200, terminal 204) that are both in areas of no cellular network coverage may communicate via a short message service, such as two terminals on two fishing boats in the ocean.
The above terminals 200 and 204, which can realize information transmission with the short message satellite 201, need to have corresponding software and hardware configurations. For example, in hardware, the terminals 200 and 204 need to be configured with a communication chip capable of communicating with the short message satellite 104, a radio frequency channel capable of receiving and transmitting signals with the short message satellite 104, and a corresponding power amplifier and a signal receiver; in software, the terminals 200 and 204 need to support short message protocols, and need to have application software supporting short message editing, sending and/or receiving. So that the terminals 200, 204 can establish an information transmission channel with the short message satellite 104. In addition, the terminals 200 and 204 are typically equipped with a subscriber identity module (subscriber identity module, SIM) card or other form of information carrier with a SIM card function (hereinafter referred to as a SIM card) for using a short message service. In the networking mode as shown in fig. 2, such a SIM card for using a short message service is generally not available for receiving a short message in a cellular communication domain or transmitting a short message to a terminal for communication using a cellular network. Compared with the short message service charge in the cellular communication domain, the short message service charge in the GNSS domain is generally higher, and the terminal needs to pay the communication charge for sending and receiving the short message through the short message satellite.
It can be seen that a terminal communicating using a cellular network cannot send and receive short messages when in an area not covered by the cellular network; although the terminal using the short message satellite for communication is not limited by the region, the terminal using the cellular network for communication cannot be used for communication, and the short message cost is higher.
In view of this, an embodiment of the present application provides a networking manner for opening up a GNSS domain and a cellular communication domain, as shown in fig. 3, so that a terminal in the GNSS domain can communicate with a terminal in the cellular communication domain; the embodiment of the application provides a terminal which can be applied to networking as shown in fig. 1 and 3, wherein the terminal can communicate through a cellular communication domain and a GNSS domain, and can use a short message service and a short message service; the embodiment of the application provides a message receiving method, which can realize the directional receiving of the message which a user wants to receive and can save the expense when the terminal receives the message (such as a short message or a short message) through a short message service.
First, a networking manner provided by the embodiment of the present application is described with reference to fig. 3. As shown in fig. 3, the short message server 303 and the short message center 304 may perform communication, so as to implement the opening of the GNSS domain and the cellular communication domain.
The short message server 303 and the short message center 304 can transmit data to realize data intercommunication and share the information received by the two. For example, the short message server 303 may send the short message received by the short message satellite 301 to the short message center 304, and the short message center 304 may also send the short message received by the short message server 303 through the base station 305.
The short message server 303 and the short message center 304 may also share end user information in two domains, such as an end user number, an end user identity (e.g., IMSI) and the like. The IMSI number is called an international mobile subscriber identity (international mobile subscriber identity, IMSI) number, which is a non-repeated identification number (e.g. 15 digits) used to distinguish between different subscribers in a communication network. The IMSI number is typically recorded in the SIM card, and the user may cause the terminal to obtain the IMSI number by equipping the terminal with the SIM card. The corresponding relationship between the user number and the IMSI number is usually recorded in the database of the operator and some network elements of the communication network (such as the sms center 304 and the sms server 303), and may be matched to the IMSI number according to the user number or be matched to the user number according to the IMSI number.
Thus, in the networking shown in fig. 3, on the one hand, the short message server 303 may send the short message received by the short message server from the terminal 300 in the GNSS domain to the short message center 304 for storage, and then the short message center 304 may send the short message to the terminal 306 in the cellular communication domain. On the other hand, the sms centre 304 may send the sms received by it from the terminal 306 in the cellular communication domain to the sms server 303, and the sms server 303 may send the sms to the terminal 300 in the GNSS domain. Therefore, the networking manner provided by the embodiment of the present application can implement the short message/short message transceiving between the terminal 300 in the GNSS domain and the terminal 306 in the cellular communication domain, and the specific transceiving process will be described in detail in the following embodiments.
In the networking manner shown in fig. 3, in yet another aspect, the short message center 304 may further send the short message from the GNSS domain stored therein to the short message server 303 again, and further the short message server 303 may send the short message to the receiving terminal in the GNSS domain.
The embodiment of the application provides a terminal which can be applied to networking as shown in figure 3. The terminal has the functions of receiving and sending short messages in a cellular communication domain and receiving and sending short messages in a GNSS domain, and can communicate in the cellular communication domain and the GNSS domain. When the terminal is in the cellular communication domain, the terminal preferably sends, receives or receives short messages through the cellular network, since the short message tariffs are typically lower than the short message tariffs. When the terminal is out of the coverage area of the cellular network, the terminal can send short messages, receive short messages or short messages through the short message satellite.
In order to realize the functions, the terminal provided by the embodiment of the application needs to be configured by adaptive software and hardware. For example, in hardware, the terminal needs to be configured with a cellular network communication chip capable of communicating with the base station 305, a short message communication chip capable of communicating with the short message satellite 301, a radio frequency module capable of transmitting and receiving signals with the base station 305, a radio frequency module capable of transmitting and receiving signals with the short message satellite 301, and one or more power amplifiers and signal receivers adapted to the communication chip and the radio frequency channel. In software, the terminal needs to support a short message protocol and a short message protocol, and has application software supporting short message editing, sending and receiving and application software supporting short message editing, sending and receiving. In addition, the terminal generally needs to be equipped with a SIM card supporting short message service and short message service.
Alternatively, the cellular network communication chip and the short message communication chip may be two chip devices or the same chip device.
Alternatively, the rf modules for receiving and transmitting signals with the base station 305 and the rf modules for receiving and transmitting signals with the short message satellite 301 may be two rf modules or the same rf module.
Alternatively, the application software supporting short message editing, sending and receiving and the application software supporting short message editing, sending and receiving may be two application software or the same application software.
Alternatively, the SIM card supporting the short message service and the SIM card supporting the short message service may be two cards (or other types of information carriers, which are described below) or may be one card.
The following describes in detail a process of transmitting a short message by using a short message service by a terminal 300 in a GNSS domain according to an embodiment of the present application with reference to fig. 3 and 4.
In step 401, the terminal 300 and the short message satellite 301 establish a channel.
Alternatively, one possible method of establishing the channel is as follows: first, the terminal 300 receives a broadcast message of the short message satellite 301, where the broadcast message includes a clock signal of the short message satellite 301, so that the terminal 300 completes clock synchronization with the short message satellite 301 according to the clock signal. Then, the terminal 300 transmits information for collision detection to the short message satellite 301 through an uplink shared channel. The uplink shared channel may be a time division multiplexed channel including a plurality of time slots, and the terminal 300 may randomly select one of the time slots to transmit the information for collision detection. If the terminal 300 receives the acknowledgement acceptance returned by the short message satellite 301, the terminal 300 knows that the time slot is available and uses the time slot as a communication channel with the short message satellite 301, otherwise, the above process is repeated until other available time slots are found.
In step 402, the terminal 300 sends the short message to the short message server 303 through the short message satellite 301.
Specifically, the terminal 300 transmits the short message to the short message satellite 301 using the channel established in the first step. The short message satellite 301 then transmits the received short message to the ground station 302, and the ground station 302 further forwards the received short message to the short message server 303. As shown in fig. 3, the ground station 302 may include a radar capable of communicating with satellites, and may further include a signal transceiver device in communication with the short message server 303; the short message server 303 has a data receiving and storing function, and can receive and store the short message sent by the short message satellite 301, and can receive and store the short message or the short message sent by the short message center 304; the short message server 303 also has a data sending function, and sends the short message stored in the short message server 303 to the short message satellite 301 through the ground station 302, or sends the short message stored in the short message server 303 to the short message center 304 in the cellular communication domain.
In step 403, the short message server 303 sends the short message to the short message center 304.
The sms center 304 is typically a service processing system or device provided by a mobile carrier in each place for submitting, storing and forwarding sms in a cellular communication domain, and provides sms services to the terminals 306 in the cellular communication domain. In the networking shown in fig. 3, as described above, the short message server 303 and the short message center 304 are opened, and may perform communication and/or data sharing, so that the short message center 304 may also receive and store the short message from the short message server 303 (or from the short message satellite 301). So that terminals 306 in the coverage area of the cellular network can also receive short messages from the short message server 303 (or from the short message satellite 301) via the cellular network.
In step 404, the sms message center 304 sends the sms message to the corresponding recipient.
The terminal device used by the recipient may be a terminal that is located within the coverage area of the cellular network and can receive the message through the cellular network, or may be a terminal that is located outside the coverage area of the cellular network and can receive the message through the short message service of the GNSS domain. The mobile terminal that receives the message through the short message service of the GNSS domain needs to have an adaptive software and hardware configuration, so as to have a function of communicating with the short message satellite 301, and the specific software and hardware configuration is as described above, which is not described herein.
If the terminal device used by the recipient is a terminal that is within the coverage area of the cellular network and can receive a short message or a short message through the cellular network, the short message center 304 may actively send the short message to the recipient terminal via the base station 305. As previously mentioned, this is typically because receiving messages using a short message service of a cellular communication network typically does not require paying a tariff.
If the terminal device used by the recipient is a terminal that is outside the coverage area of the cellular network and can receive the message through the short message service of the GNSS domain, the short message center 304 will not normally actively send the short message, but will send the short message to the recipient terminal after the short message center 304 receives the short message receiving request of the recipient. As previously mentioned, this is typically because the recipient who receives the message via the short message satellite using the short message service also needs to pay a fee. The short message center 304 sends a short message to such recipients as follows: the short message center 304 firstly sends the short message to the short message server 303, the short message server 303 then sends the short message to the short message satellite 301 through the ground station 302, and finally the short message satellite 301 sends the short message to the recipient terminal.
The above steps are executed, thereby completing the process of sending short messages by using the short message service.
Optionally, if the terminal device used by the recipient in step 404 is outside the coverage area of the cellular network and can receive the message through the short message service of the GNSS domain, the whole flow shown in fig. 4 may not include step 403, that is, the process of sending the short message to the short message center 304 by the short message server 303. That is, the short message is not stored in the short message center 304 at this time, but may be stored by the short message server 303, after the short message server 303 receives the shoujianrend short message receiving request, the short message is sent to the short message satellite 301 through the ground station 302, and finally the short message satellite 301 sends the short message to the recipient terminal.
Next, a process of receiving a message by using a short message service by a terminal 300 in a GNSS domain according to an embodiment of the present application will be described in detail with reference to fig. 3 and 5. As mentioned above, the above-mentioned messages may be short messages and short messages. Based on the networking manner shown in fig. 3, the terminal 300 outside the coverage area of the cellular network may receive the short message sent from the cellular communication domain through the short message satellite 301, or may receive the short message sent from the GNSS domain through the short message satellite 301.
In step 501, the terminal 300 and the short message satellite 301 establish a channel.
The process of establishing the channel is the same as the previous process (step 401), and will not be repeated here.
In step 502, the terminal 300 sends a message receiving request to the short message server 303 through the short message satellite 301.
Specifically, the terminal 300 transmits a message reception request to the short message satellite 301 using the channel established in the first step. The short message satellite 301 then transmits the received message reception request to the ground station 302, and the ground station 302 further forwards the message reception request to the short message server 303. The message receiving request may generally include a subscriber identity (e.g., IMSI) of the terminal 300. The short message server 303 or the short message center 304 may retrieve the short message and/or the short message with the recipient number corresponding to the user identity code from the storage space according to the user identity code of the terminal 300, so as to send the short message and/or the short message to be sent to the recipient.
In step 503, the short message server 303 obtains the message stored in the short message center 304 and received as the terminal 300.
Specifically, first, the short message server 303 may send a message receiving request to the short message center 304. The sms centre 304 then retrieves the message to the recipient terminal 300 from the storage space of the sms centre 304 in response to the message acceptance request (e.g. in response to the IMSI number in the message acceptance request). The message may be a short message sent by the sending terminal through a short message service in the GNSS domain, or a short message sent by the sending terminal through a short message service in the cellular communication domain. And the short message center 304 sends the searched message with the recipient being the terminal 300 to the short message server 303. So that the short message server 303 obtains the message to the recipient artificial terminal 300.
In step 504, the short message server 303 sends the message to the terminal 300 via the short message satellite 301.
Specifically, short message server 303 sends a message to ground station 302 that is received as terminal 300, and ground station 302 further forwards the message to short message satellite 301. And the short message satellite 301 sends the message to the terminal 300 via the downlink channel.
The above steps are performed, thereby completing the process of receiving a message using the short message service.
Alternatively, in the above step 503, the short message server 303 may not obtain the message with the recipient as the terminal 300 from the storage space of the short message center 304, but obtain the message with the recipient as the terminal 300 from the storage space of the short message server 303 itself. The premise of this alternative is that the sms centre 304 can send the received sms to the sms server 303 in a shared manner and store the sms in the storage space of the sms server 303, and the sms server 303 also stores the received sms in its own storage space.
As described above, the networking shown in fig. 3 provided by the embodiment of the present application opens up the GNSS domain and the cellular communication domain, so that a terminal outside the coverage area of the cellular network may also receive a short message in the cellular communication domain. However, there are often a large number of spam messages, such as advertisements, fraud messages, among the messages in the cellular communication domain. When a user receives a short message through a short message service in a place outside the coverage area of a cellular network by using the terminal provided by the embodiment of the application, a large amount of junk short messages can be received, and high short message service communication tariffs are generated, which are not hoped to be seen by the user. Alternatively, the receipt of a short message which is not critical to the user and is not urgent, the user does not wish to receive such a short message through the short message service, which causes a premium, but wishes to receive the short message free of charge when the terminal is again available for receiving the short message through the cellular network. Besides the problem that a great deal of expense is generated for users, on the other hand, the downlink channel resources of the short message satellite are usually limited, and the terminal can occupy the system resources of the short message service when receiving a great deal of short messages through the downlink channel of the short message satellite.
In view of this, the embodiment of the application provides a message receiving method, which can realize the directional receiving of the message which the user wants to receive, so that the user can more effectively acquire the required message, and reduce the messages which the user does not want to receive or some non-urgent messages, thereby saving the cost when the terminal receives the message through the short message service.
Specifically, in the message directional receiving method provided by the embodiment of the application, the terminal receives the message through the short message service, and as described above, the terminal firstly needs to send a message receiving request to the short message server through the short message satellite. The message directional receiving method provided by the embodiment of the application is different from the process shown in fig. 5 in that the message receiving request sent by the terminal includes, in addition to the terminal user identity (e.g. IMSI) number, the sender number of the message that the receiving terminal user wishes to receive. The sender number may be a number of the second electronic device, for example an MSISDN number or an IMSI number of the second electronic device. The MSISDN number is referred to as mobile subscriber international number (mobile subscriber international ISDN/PSTN number). Alternatively, the MSISDN code may comprise a two-digit Country Code (CC), a three-digit national destination code (national destination code, NDC), and an eight-digit customer number (subscriber number, SN). Alternatively, the above MSISDN number may also refer to an eleven-digit number comprising a three-digit NDC and an eight-digit SN.
According to the message receiving request, the short message server obtains the message of which the recipient is the terminal user and the sender number is the sender number of which the receiving terminal user wants to receive the message from the short message center (or from the storage space of the short message server). And then the short message server sends the message meeting the conditions to the terminal through the short message satellite, so that the terminal achieves the effect of directionally receiving the message.
Fig. 6 illustrates two message receiving requests provided by the embodiments of the present application that can be used in the message direction accepting method described above.
The message receiving request shown in fig. 6 (a) includes the IMSI number of the recipient terminal and a sender number a of the message that the recipient terminal user wishes to receive. That is, the recipient end user wishes to send a message via short message service receiving number a ("189 xxxx xxxx") and does not wish to send a message via a number other than short message service receiving number a.
The message receiving request shown in fig. 6 (b) includes the IMSI number of the recipient terminal and three sender numbers A, B and C of the recipient terminal user desiring to receive the message. That is, the recipient end user wishes to receive messages sent by short message service receiving numbers a ("189 xxx"), B ("136 xxx") and C ("158 xxx"), and does not wish to send messages by other numbers than short message service receiving numbers A, B and C.
It should be clear that the message directional receiving method provided by the embodiment of the application does not limit the number of sender numbers contained in the message receiving request sent by the terminal, and the number can be one or a plurality. The end user may customize the sender number that it wishes to receive the message, e.g., the recipient number may be added or removed by interaction with the terminal display interface.
Fig. 7 illustrates a flow chart of a message directional receiving method according to an embodiment of the present application. The following describes in detail the process of the terminal to receive messages through the short message service in a directed manner with reference to fig. 3, 6 and 7.
In step 701, the terminal 300 and the short message satellite 301 establish a channel.
The process of establishing the channel is the same as the previous process (step 401, step 501), and will not be repeated here.
In step 702, the terminal 300 sends a message receiving request including the user id and the sender number of the terminal 300 to the short message server 303 through the short message satellite 301.
Specifically, the terminal 300 transmits the above-described message reception request to the short message satellite 301 using the channel established in the first step. The short message satellite 301 then transmits the received message reception request to the ground station 302, and the ground station 302 further forwards the message reception request to the short message server 303.
As described above, the message directional receiving method provided by the embodiment of the application realizes the message directional receiving by adding the sender number of the message which the terminal user wants to receive in the message receiving request. Therefore, the message receiving request includes, on the one hand, the user identity (e.g., IMSI number) of the terminal 300, for retrieving the short message with the recipient being the user of the terminal 300; and on the other hand, the sender number, i.e. the sender number of the message which the end user wants to receive, is also included for matching to the message which the sender number is the sender number of the message which the user wants to receive.
In step 703, the short message server 303 obtains the message stored in the short message center 304, where the recipient is the user of the terminal 300 and the sender number matches the sender number in the message receiving request.
Specifically, first, the short message server 303 may send the above-mentioned message receiving request to the short message center 304. The short message center 304 then retrieves and matches the message from the storage space of the short message center 304 according to the message reception request, the message having a recipient number matching the user identification code of the terminal 300 in the message reception request and a sender number matching the sender number in the message reception request. Further, the short message center 304 transmits a message meeting the above conditions to the short message server 303. So that the short message server 303 obtains the message to the recipient artificial terminal 300 with the sender number matched with the sender number in the message reception request.
In step 704, the short message server 303 sends the message to the terminal 300 through the short message satellite 301.
Specifically, the short message server 303 sends a message that the recipient is the terminal 300 and that the sender number matches the sender number in the message reception request to the ground station 302, and the ground station 302 further forwards the message to the short message satellite 301. The short message satellite 301 then transmits the message to the terminal 300 via the downlink channel.
The above steps are performed so as to complete the process of directionally receiving the message using the short message service.
Alternatively, similar to the process shown in fig. 5, in step 703 in the process shown in fig. 7, the short message server 303 may obtain the message of the recipient as the terminal 300 from the storage space of the short message center 304, but may obtain the message of the recipient as the terminal 300 from the storage space of the short message server 303 itself. The precondition for this alternative is the same as for the alternative of the process shown in fig. 5 and will not be repeated here.
The message orientation receiving method provided by the embodiment of the application can be applied to a scene that a terminal still hopes to receive a message through the short message service of a satellite when the terminal is positioned at a place outside the coverage area of a cellular network. The terminal, when outside the coverage area of the cellular network, cannot establish a connection with a base station in the cellular network and thus cannot receive messages through the cellular network. At this time, a plurality of messages with recipients as end users may be temporarily stored in the short message center. For example, the above-mentioned message may include a message that the user wants to receive in time, such as a message sent by a family member or a colleague, or may include a message that the user does not need to receive in time, such as a message that an online shopping product has been shipped and a package has been put in an express cabinet, or may include a message that the user does not want to receive, such as a spam message, a fraud message, or an advertisement message.
At this time, the terminal transmits a message receiving request to the short message satellite. If the message receiving request does not contain the sender number which the user wants to receive, the terminal receives all the messages which are temporarily stored in the short message center and serve as the terminal user through the short message satellite. This may include many of the types of messages described above, resulting in a higher short message service tariff. On the other hand, if a large number of terminal users use the short message service to receive all types of messages, a large amount of load is also brought to the limited downlink channels of the short message satellite, and the short message service quality is reduced.
In the message directional receiving method provided by the embodiment of the application, the message receiving request sent by the terminal to the short message satellite contains the sender number of the short message which the user hopes to receive through the short message service besides the user identification code of the terminal. And the short message center matches the sender number of the message to the message meeting the conditions according to the sender number of the message which the user hopes to receive through the short message service, and only sends the message meeting the conditions to the short message server. And the terminal only contains the information sent by the sender number of the information which the user hopes to receive through the short message service, thereby realizing the directional receiving of the information, obtaining the beneficial effect of saving the expense of the user for using the short message service, enabling the user to obtain the needed short message more effectively, and reducing the unnecessary information and/or the information which the user does not hope to receive.
Fig. 8 schematically illustrates information transceiving of each network element according to an embodiment of the present application. As shown in the figure:
s100, searching satellites by the terminal, and establishing a short message receiving channel. This step is similar to steps 401, 501 and 701 described previously and is not repeated here.
S101, the terminal sends a message receiving request to the short message satellite. As shown in fig. 8, the message acceptance request includes the IMSI number of the terminal and a sender number ("189 xxxx xxxx"), so that the terminal can receive the message sent by the sender in a targeted manner.
S102, the short message satellite sends a message receiving request to a short message server. Specifically, the message receiving request sent by the short message satellite is received by the ground station, and then the ground station forwards the message receiving request to the short message server.
S103, the short message server sends a message receiving request to the short message center.
S104, the short message center performs sender matching. Specifically, the short message center matches the message to the recipient terminal according to the terminal IMSI code and the sender number in the message receiving request, and the sender number matches the sender number in the message receiving request. The message may be a short message sent by the sending terminal in the cellular communication domain to the short message center through the base station, or a short message sent by the sending terminal in the GNSS domain to the short message server through the short message satellite and then to the short message center, or both.
S105, the short message center sends the information to the short message server. Specifically, the short message center sends the matched message meeting the condition to a short message server.
S106, the short message server sends the message to the short message satellite. Specifically, the short message server sends the received message from the short message center to the ground station, and then the ground station forwards the message to the short message satellite.
S107, the short message satellite sends a message to the terminal. Specifically, the short message satellite transmits the message to the terminal through a downlink channel.
Fig. 9 schematically illustrates another embodiment of information transceiving of various network elements according to the present application. As shown in the figure:
steps S200, S201, S202 are the same as steps S100, S101, S102 in the process shown in fig. 8, and will not be repeatedly described here.
S203, the short message server performs sender matching. Specifically, the short message server matches the message to the recipient terminal according to the terminal IMSI code and the sender number in the message receiving request, and the sender number matches the sender number in the message receiving request. The message may be a short message sent by the sender terminal in the cellular communication domain to the short message center through the base station, and then sent by the short message center to the short message server, or a short message sent by the sender terminal in the GNSS domain to the short message server through the short message satellite, or both.
S204, the short message server sends the message to the short message satellite. Specifically, the short message server sends the message to the ground station first, and then the ground station forwards the message to the short message satellite.
S205, the short message satellite sends a message to the terminal. Specifically, the short message satellite transmits the message to the terminal through a downlink channel.
Fig. 10 is an exemplary schematic diagram of an interactive interface for receiving a message by the terminal through a short message service according to an embodiment of the present application.
The user can customize the sender number he wishes to receive a message via a short message service. For example, as shown in fig. 10 (a), in the short message setup menu, the user can add or remove a number allowing a message to be received through the short message service. Currently, the user sets messages that allow the terminal to receive dad (number "198xxx xxxx"), mom (number "136xxx xxxx") and sister (number "158xxx xxxx") through the short message service. The user can click on the remove button to delete the added number, or click on the add button beside the add number or the add number to add a new number. For example, adding contacts in an address book, or manually entering a new number, etc. When the user performs the above setting, the terminal may be located within the cellular communication coverage area or may be located outside the cellular communication coverage area. Fig. 10 (a) illustrates an exemplary setting of a short message service recipient number by a user in the presence of a cellular signal, although it should be understood that this is not a limitation of embodiments of the present application. Similarly, the other interface elements in FIG. 10 are not limiting of embodiments of the application, but merely serve as an example of one possible implementation.
The user can click on "receive short message" to make the terminal receive message using short message service. As shown in fig. 10 (b), the terminal is currently in an "out-of-service" area, i.e., an area outside the coverage area of the cellular communication network, where the terminal cannot receive messages through the base station. If the user still wants to receive the message of the other user in time at this time, the user can use the short message service. The user may click a plus icon at the lower right corner of the interface shown in fig. 10 (b), pop up a menu in the interface, and click a "receive short message" button in the menu, so as to trigger the terminal to start executing a series of processes of receiving a message through the short message service, where the processes may include steps 701 and 702 shown in fig. 7. The terminal firstly establishes a channel for communication with the short message satellite, and then sends a message receiving request to the short message satellite. The message acceptance request may include the terminal IMSI number and numbers of three persons dad, mom, and sister shown in fig. 10 (a).
The terminal receives the message through the short message service. As shown in fig. 10 (c), after the user clicks the "receive short message" button shown in fig. 10 (b), the terminal successfully receives two messages sent to the user by dad. The prompt information of the two messages can be displayed in the form of bold content preview and unread message number in the terminal short message dialogue list. The user can further click on the short message dialogue with "dad" to enter dialogue content and view these two new messages, as shown in fig. 10 (d).
Before the user clicks the "receive short message" button as shown in fig. 10 (b), the two messages are temporarily stored in the short message center because the terminal is outside the coverage area of the cellular network and cannot receive messages through the base station. After the user clicks the "receive short message" button as shown in fig. 10 (b), the short message satellite receives a message reception request of the terminal and transmits the message reception request to the short message server via the ground station. And then the short message server sends the message receiving request to a short message center. The message center analyzes the message receiving request, and matches the message meeting the condition according to the IMSI code and the sender number in the message receiving request, namely, the message with the recipient being the terminal user and the sender number being matched with the sender number in the message receiving request. The short message center sends the message meeting the conditions to the short message server, and then the short message server sends the message meeting the conditions to the short message satellite through the ground station. And finally, the short message satellite sends the message meeting the condition to the terminal.
The embodiment of the application provides a message receiving method which is applied to a communication network comprising a message center and can realize the directional receiving of a message, wherein the specific process is as follows:
Specifically, when the network user a in the communication network transmits a message to the network user B, first, the network user a transmits the message directly or indirectly to the message center.
The hub then determines whether to send the message directly or indirectly to network user B based on the list of permitted receptions of network user B. That is, if the permission receiving list includes network user a or user identification information related to network user a, the message center determines that the message should be sent to network user B, and then the message center directly or indirectly sends the message to network user B. If the permission acceptance list does not contain the network user A or the user identification information related to the network user A, the message center judges that the message should not be sent to the network user B, and the message center does not directly or indirectly send the message to the network user B.
Alternatively, the grant receiving list may be sent directly or indirectly to the message center by the network user B before the message center receives the message sent by the network user a to the network user B. Alternatively, the permission receiving list may be stored in advance in a storage space of the message center. Alternatively, the permission receiving list may be acquired from a storage space of another device by the message center.

The above embodiments provided by the present application are explained taking the short message service provided by the beidou satellite as an example. However, it should be clear that the scenario in which the embodiments of the present application may be applied is not limited to the short message service provided by the beidou satellite, but may be other satellite communication services or other non-satellite communication services. The message directional receiving method provided by the application is applied to other scenes, and can also realize the beneficial effects of reducing the messages which are not expected to be received by a receiving user or are not required to be received in time, and improving the efficiency of obtaining the messages by the user.
The network elements related to the above embodiments provided by the present application are network elements in the current cellular communication domain and GNSS domain, but it should be clear that the present solution is not limited to the application scenario of each embodiment, and each network element must be included.
In the above embodiments provided in the present application, an IMSI number is used as one possible way of using an end user id as an example, but it should be clear that the embodiments of the present application are not limited to the type of end user id. The end user identification code may also be a temporary mobile subscriber identification (temporary mobile subscriber identity, TMSI) code, a mobile subscriber international number (mobile subscriber international ISDN/PSTN number, MSISDN), a universal unique identification code (universally unique identifier, UUID) or other type of identification code.
The embodiment provided by the application is not limited to the scenes of receiving and sending short messages through the Beidou short message satellite, and can be also applied to the scenes of receiving and sending short messages through the cellular communication network. For example, the terminal may send a message reception request to the short message center through the base station, where the message reception request includes the terminal user identification code and the sender user number from which the user wishes to receive the message. The short message center searches the number which matches the addressee number as the number corresponding to the terminal user identity code and the sender user number as the number which matches the sender user number in the message receiving request, and then the short message center transmits the message meeting the above conditions to the terminal through the base station. Therefore, the short message center can preferentially send messages of some sender user numbers to the terminal to be sent to the terminal user numbers when cellular communication resources are limited, or completely send no messages of other sender user numbers except the some sender user numbers to be sent to the terminal user numbers. Some of the sender user numbers may be sender user numbers that the user included in the message reception request wishes to receive a message. Thereby achieving the beneficial effect of reducing the occupation of cellular communication resources or helping the user to shield messages that the user does not wish to receive.
