Description

Technical Field

[0001] The present invention relates to the field of communications, and in particular to a method and system for a terminal to identify Tiantong short messages and common short message services. Background Art

[0002] With the continuous development of satellite communication technology, especially the successful application of the Tiantong satellite system independently developed by my country, satellite communication has played an important role in areas that cannot be covered by ground mobile communication networks such as oceans and remote areas. The Tiantong satellite system provides voice, SMS and packet data services, providing users with reliable communication guarantees. However, in actual applications, since Tiantong SMS is similar to ordinary SMS in terms of transmission method and coverage, users often find it difficult to distinguish the type of SMS received. The existing technology mainly distinguishes the type of SMS through terminal identification, but this identification is one-sided, which leads to a large number of SMS received, and the identification not only has a long processing time, but also has higher requirements for the terminal processing system, requiring not only higher running memory, but also more accurate data processing. It often causes the terminal processing system to crash, causing inconvenience and misunderstanding in user use. Summary of the invention

[0003] The purpose of the present invention is to solve the inconvenience and possible misunderstanding in the one-way process used in the prior art to identify the categories of Tiantong SMS and ordinary SMS, and to propose a method and system for a terminal to identify Tiantong SMS and ordinary SMS services.

[0004] In order to achieve the above object, the present invention adopts the following technical scheme:

[0005] A method for a terminal to identify a Tiantong SMS and a common SMS service, comprising the following steps:

[0006] S1: SMS gateway receiving: The SMS gateway receives SMS messages from different networks, parses the SMS content according to preset rules, and then distinguishes the services and performs special identification;

[0007] S2: Communication network transmission: The marked SMS is transmitted to the user terminal through the router and switch;

[0008] S3: User terminal receives: After receiving the identified SMS, the SMS content is parsed through the physical channel of the called terminal and the built-in software algorithm to determine whether it is a Tiantong SMS;

[0009] S4: User terminal display: The identified SMS type result is dynamically displayed on the user terminal.

[0010] Preferably, the specific steps of service differentiation and identification of the SMS gateway are:

[0011] S101: distinguishing and determining whether to display a satellite SMS logo, based on route analysis and the type of service contracted by the roaming user;

[0012] S102: Marking: when it is determined that a satellite SMS identification needs to be added and displayed on the called terminal, a satellite SMS display identification field is added to the From header field of the SMS;

[0013] S103: Identification: Send the SMS with the satellite SMS display mark field added to it to the called domain SBC, and the called domain SBC displays the satellite SMS service according to the From header field; if the called domain SBC determines that the From header field of the received SMS does not contain the satellite SMS display change identification field, then no P-Asserted-Identity header field is added, otherwise it is directly sent to the called terminal.

[0014] Preferably, the physical channel resolution of the called terminal involves a baseband chip and a communication module of the called terminal.

[0015] Preferably, the specific steps of physical channel resolution of the called terminal are as follows:

[0016] S301: receiving processing, used to receive signals. When the called terminal is in standby or communication state, its communication module will continuously monitor the wireless signals from the base station or satellite;

[0017] S302: Content parsing: the SMS processing module will parse the SMS content according to the communication protocol GSM or CDMAJ, including the header information and the text content of the SMS;

[0018] S303: Type differentiation: Based on the parsed content, the SMS processing module and the software algorithm determine the type of the SMS. When an SMS signal is received, the communication module converts it into a digital signal and passes it to the processing module of the called terminal. The processing module parses these digital signals, extracts the From header field information and the P-Asserted-Identity header field information in the SMS request, and uses the software algorithm to determine the type.

[0019] Preferably, the specific steps of the software algorithm judgment are:

[0020] a. Data structure preparation: First, define the SMSMessage class to store each SMS message;

[0021] b. SMS query and basic information acquisition: Get the SMS content Uri through Telephony.Sms.CONTENT_URI and specify the field to be queried; use ContentResolver to query the SMS Uri, get the Cursor object, and then get the index corresponding to each field;

[0022] c. Determine the type of SMS: Check the obtained index header information. If it contains the tag to extract the P-Asserted-Identity header information, that is, the SMS contains the special tag of Tiantong SMS, then it is identified as Tiantong SMS, otherwise it is regarded as a normal SMS;

[0023] d. Determine whether to intercept. If it is a common SMS, intercept it directly. If it is a Tiantong SMS, determine whether the Tiantong SMS is the required SMS. The verification condition is based on the terminal code and matching code preset rules. The specific steps of the judgment are: obtain the terminal code of the Tiantong SMS, and at the same time detect the matching code preset by the called terminal detection module, and perform rule verification on the terminal code and the matching code. If the terminal code and the matching code do not meet the verification conditions, intercept it directly, and proceed to the next step if it meets the verification conditions;

[0024] f. Construct and store SMS message objects: classify and store the Tiantong SMS messages containing different terminal code pairs so that all the read SMS messages can be processed and analyzed uniformly later.

[0025] Preferably, according to the method for the terminal to identify Tiantong SMS and ordinary SMS services, a system for the terminal to identify Tiantong SMS and ordinary SMS services is also provided, including an SMS gateway, a communication network and a called terminal, the called terminal including a communication module, a processing module and a storage module, the communication module processes wireless communication signals, including the reception and sending of SMS, the processing module includes a baseband chip and a radio frequency module, and the SMS content is parsed by modifying or optimizing the baseband chip and software algorithm, and the storage module saves the received SMS content so that the user can view it at any time.

[0026] Preferably, the SMS gateway further includes an application server AS, which includes a first SMS acquisition module, a first judgment module, a first processing module and a first sending module; wherein the first SMS acquisition module is used to acquire SMS, the From header field of which does not contain a satellite SMS display change identification field, the first judgment module determines whether to add a satellite SMS identification displayed on the called terminal based on routing analysis and the type of service contracted by the roaming user, the first processing module adds a satellite SMS display change identification field in the From header field when determining that the satellite SMS service displayed on the called terminal needs to be changed, and the first sending module sends the SMS processed by the first processing module;

[0027] Preferably, the called terminal also includes a called domain SBC, and the called domain SBC includes a second SMS acquisition module, a second judgment module, a second processing module and a second sending module. The second SMS acquisition module receives SMS from the application server AS, and the second judgment module determines whether the From header field of the received SMS contains a satellite SMS display change identification field. When the second processing module determines that the From header field of the received SMS contains a satellite SMS display change identification field, a trusted entity identification P-Asserted Identity header field is added to the SMS. The second sending module sends the SMS processed by the second processing module to the called terminal, so that the called terminal displays the satellite SMS service according to the information in the P-Asserted-Identity header field.

[0028] Preferably, the called terminal further comprises an identification module and a display module, the display module is connected to the user display interface signal, the identification module classifies the information sent by the second sending module and sends them to the user display interface respectively, and a type identification display area is added to the user display interface.

[0029] The beneficial effects of the present invention are:

[0030] 1. At the SMS gateway level, the present invention uses intelligent recognition algorithms to parse the content of received SMS messages. These algorithms can identify whether the SMS contains specific prefixes, keywords or fields in a specific format. These identifiers are the key to distinguishing Tiantong SMS from ordinary SMS. Once the SMS is identified as Tiantong SMS, the gateway will mark it specially, such as adding a specific identifier or modifying a field of the SMS, so that its type can be identified during subsequent transmission and processing.

[0031] 2. The marked Tiantong SMS and ordinary SMS are then transmitted to the called terminal through the communication network. During this process, the SMS gateway ensures that the special mark of the Tiantong SMS is not modified or deleted during the transmission process. Secondly, the physical channel analysis and software algorithm of the called terminal can read the special mark in the SMS, and judge whether the SMS is a Tiantong SMS based on this, and can identify specific Tiantong SMS in different fields.

[0032] 3. The called terminal displays the message on the display module and displays the Tiantong SMS and ordinary SMS in categories. This area is used to display the type of SMS, i.e. Tiantong SMS or ordinary SMS. When the terminal receives the SMS and parses its type, it will update the display content of this area accordingly.

[0040] See also Figure 1 , a method for a terminal to identify Tiantong SMS and ordinary SMS services, comprising the following steps:

[0041] S1: SMS gateway receiving: The SMS gateway receives SMS messages from different networks, parses the SMS content according to preset rules, and then distinguishes the services and performs special identification;

[0042] S2: Communication network transmission: The marked SMS is transmitted to the user terminal through the router and switch;

[0043] S3: User terminal receives: After receiving the identified SMS, the SMS content is parsed through the physical channel of the called terminal and the built-in software algorithm to determine whether it is a Tiantong SMS;

[0044] S4: User terminal display: The identified SMS type result is dynamically displayed on the user terminal.

[0045] The specific steps of service differentiation and identification of the SMS gateway are as follows:

[0046] S101: distinguishing and determining whether to display a satellite SMS logo, based on route analysis and the type of service contracted by the roaming user;

[0047] S102: Marking: when it is determined that a satellite SMS identification needs to be added and displayed on the called terminal, a satellite SMS display identification field is added to the From header field of the SMS;

[0048] S103: Identification: Send the SMS with the satellite SMS display mark field added to it to the called domain SBC, and the called domain SBC displays the satellite SMS service according to the From header field; if the called domain SBC determines that the From header field of the received SMS does not contain the satellite SMS display change identification field, then no P-Asserted-Identity header field is added, otherwise it is directly sent to the called terminal.

[0049] The physical channel resolution of the called terminal involves the baseband chip and the communication module of the called terminal.

[0050] The specific steps of physical channel resolution of the called terminal are as follows:

[0051] S301: receiving processing, used to receive signals. When the called terminal is in standby or communication state, its communication module will continuously monitor the wireless signals from the base station or satellite;

[0052] S302: Content parsing: the SMS processing module will parse the SMS content according to the communication protocol GSM or CDMAJ, including the header information and the text content of the SMS;

[0053] S303: Type differentiation: Based on the parsed content, the SMS processing module and the software algorithm determine the type of the SMS. When an SMS signal is received, the communication module converts it into a digital signal and passes it to the processing module of the called terminal. The processing module parses these digital signals, extracts the From header field information and the P-Asserted-Identity header field information in the SMS request, and uses the software algorithm to determine the type.

[0054] Specifically, the main processing steps are:

[0055] SMS reception and processing:

[0056] When the called terminal is in standby or communication state, its communication module will continuously monitor the wireless signal from the base station or satellite. When receiving the SMS signal, the communication module will convert it into a digital signal and pass it to the processing module of the called terminal.

[0057] The SMS processing software of the processing module will parse these digital signals and extract information such as the content of the SMS, sender number, timestamp, etc.

[0058] Content analysis:

[0059] The SMS processing software will parse the SMS content according to the formats specified by communication protocols (such as GSM, CDMA, etc.). These formats usually include the header information of the SMS (such as service type, sender address, etc.) and the body content. During the parsing process, the software will identify special identifiers or fields in the SMS.

[0060] Type differentiation:

[0061] Based on the parsing result, the SMS processing software will determine the type of the SMS. If the SMS contains the special mark of Tiantong SMS, it will be identified as Tiantong SMS; otherwise, it will be regarded as an ordinary SMS.

[0062] Specific prefix or suffix: Tiantong SMS may add a specific prefix or suffix before or after the SMS content. These prefixes or suffixes are predefined and used to indicate the type or source of the SMS. For example, a prefix like "

Tiantong

[0063] Specific keywords: Specific keywords or phrases are embedded in the SMS content. These keywords or phrases are the key to differentiating Tiantong SMS from ordinary SMS. These keywords may be fixed or dynamically generated according to the protocol. When the terminal receives an SMS and parses its content, it will check whether these specific keywords exist to determine the type of the SMS.

[0064] Specific fields: Specific fields are added to the protocol header or specific positions of the SMS. These fields contain information about the type of the SMS. For example, a flag bit can be set in a certain field of the SMS. When this flag bit is set to a specific value, it indicates that this SMS is Tiantong SMS.

[0065] The specific steps for the software algorithm to judge are as follows:

[0066] a. Data structure preparation: First, define the SMSMessage class to store each SMS;

[0067] b. SMS query and basic information acquisition: Obtain the Uri of the SMS content through Telephony.Sms.CONTENT_URI and specify the fields to be queried; use ContentResolver to perform a query operation on the SMS Uri. After obtaining the Cursor object, obtain the indexes corresponding to each field;

[0068] c. Determine the type of the SMS: Detect the obtained index header field information. If it contains the mark to extract the P-Asserted-Identity header field information, that is, the SMS contains the special mark of Tiantong SMS, it will be identified as Tiantong SMS; otherwise, it will be regarded as an ordinary SMS.

[0069] d. Determine whether to intercept. If it is a common SMS, intercept it directly. If it is a Tiantong SMS, determine whether the Tiantong SMS is the required SMS. The verification condition is based on the terminal code and matching code preset rules. The specific steps of the judgment are: obtain the terminal code of the Tiantong SMS, and simultaneously detect the matching code preset by the called terminal detection module, and perform rule verification on the terminal code and matching code. If the terminal code and matching code do not meet the verification conditions, intercept directly; if they meet the conditions, proceed to the next step;

[0070] f. Construct and store SMS message objects: classify and store the Tiantong SMS messages containing different terminal code pairs so that all the read SMS messages can be processed and analyzed uniformly later.

[0071] The specific steps are as follows:

[0072] Data structure preparation:

[0073]

[0074]

[0075] Core algorithm for parsing SMS content and determining type

[0076]

[0077]

[0078]

[0079] Interception example:

[0080] Because there are many categories of Tiantong SMS, including SMS in different fields, once all Tiantong SMS are received, the called terminal server will crash. The software algorithm is only used for preliminary screening, and all Tiantong SMS are screened again through specific verification rules, for example:

[0081] The terminal code of the Tiantong SMS is: TG00010001X, and the matching code preset in the called terminal detection module is: TG00010001X. If it meets the conditions during verification, it is determined to be the required Tiantong SMS and will not be intercepted. The terminal code is directly determined through the communication protocol. For example, the terminal code in the geological field is: TG00010001X, and the terminal code in the meteorological field is: TG00010002R.

[0084] Reference Figure 5 When a satellite network user sends a text message to an IMS user, after the routing analysis of the IMS network, the call request will be sent from the satellite network switch to the IP-SM-GW in the IMS user's home network. After receiving the ISUP / BICC signaling message, the IP-SM-GW interacts with the SMS-SC to create a user plane connection. The IP-SM-GW will also convert the ISUP / BICC signaling into SIP signaling and send a MESSAGE message to the I-CSCF.
