Short message service control method and device, electronic equipment and storage medium

Abstract

The application provides a short message service control method and device, electronic equipment and storage medium. The method is applied to a service call session control function (S-CSCF) network element, and comprises the following steps: receiving a session initiation protocol (SIP) message sent by a user equipment (UE), wherein the SIP message encapsulates a short message; when the SIP message does not include a reply parameter of a short message single stop iFC, the SIP message is transferred to a set network element on a server side for processing or the SIP message is discarded. In the embodiment of the application, the reply parameter of the short message single stop iFC is judged by the S-CSCF, so that the short message single stop is no longer controlled by an eSMSC, but is controlled by a trigger condition preset by the iFC through the S-CSCF. The reply parameter is ingeniously applied in the short message single stop iFC trigger rule, that is, no additional investment is increased, and no network architecture is changed, so that the purpose of real-time short message single stop is achieved.

Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a method, apparatus, electronic device, and computer-readable storage medium for controlling short message services. Background Technology

[0002] In related technologies, the suspension of a user's short message service is configured by the enhanced short message center (eSMSC). The eSMSC handles failures based on the user's suspension service attributes. That is, the eSMSC can configure a user's short message service to be either single-stop or double-stop. For single-stop service, the user only needs to control the short message sending process, ensuring the user can receive short messages but cannot send them. For double-stop service, the eSMSC can not only control the short message sending process but also prevent the sending of short messages based on the double-stop service attribute, and correctly send status report messages to the sending eSMSC, such as MESSAGE (TP-STATUS) or SMDPP (Deliery Acknowledgement).

[0003] Therefore, in related technologies, the single (or double) suspension of SMS services is controlled by the eSMSC. However, the control of users' single (or double) suspension services by the eSMSC requires the support of eSMSC hardware and software licenses, which requires additional investment and thus increases operating investment costs. Summary of the Invention

[0004] This invention provides a method, apparatus, electronic device, and storage medium for controlling short message services, to at least solve the problem in related technologies where the control of a user's single (or double) suspended service by the eSMSC requires eSMSC hardware and software licenses, leading to increased operational investment costs.

If the SIP message does not include a reply parameter for short message single-stop iFC (Instant Message Stop), the SIP message is forwarded to a designated network element on the server side for processing or discarded. In other words, in this embodiment of the invention, the S-CSCF determines the "reply" parameter for "short message single-stop iFC," so that the single-stop of short messages is no longer controlled by the eSMSC, but by the triggering conditions preset by the iFC through the S-CSCF. This is cleverly applied within the "short message single-stop iFC" triggering rules, without adding extra investment or changing the network architecture, thereby achieving the goal of real-time single-stop of short messages.

[0069] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0070] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0071] First, let's introduce the technical terms involved in the embodiments of this invention:

[0072] AS (Application Server): This is the top-level application layer device in the IMS system, providing basic and supplementary services, multimedia conferencing, unified communications, SMS gateways, standard operator consoles, and other services. The IMS network is an open system based on IP that provides various multimedia services to users. AS network elements and CSCF interact through the standard SIP protocol to trigger and execute various network services.

[0073] BAC (Border Access Controller): Also known as SBC (Session Border Controller), it has gradually become a standard configuration product in IMS networks. Positioned as the ABG (access border gateway) of the IMS network, it solves problems such as NAT / FW traversal, security, interoperability, and QoS.

[0074] eSMSC (Enhanced Short Message Service Center): Compared to SMS, its advantage lies in its ability to send simple images, sounds, and animations in addition to text messages. Its biggest advantage is that EMS can still operate on the same GSM networks used by SMS, without any difference in sending methods or operation. The standard is open, so any third-party company or individual interested in EMS can develop applications and services on this platform. It can combine simple ringtones, pictures, and even animations with text, sending them between EMS-enabled mobile phones.

[0075] DNS (Domain Name Service): The Domain Name System assigns domain names and IP addresses to hosts on the network. When a user uses a domain name, the system automatically translates it into an IP address.

[0076] HSS (Home Subscriber Server): The HSS supports the main user database for IMS network entities that handle calls / sessions. It includes user profiles, performs user authentication and authorization, and provides information about the user's physical location. The entities communicating with the HSS are the Application Server (AS) and the Call Session Control Function Server (CSCF), where the Application Server hosts the IMS environment and executes its services. The user profile includes information about the current user—typically, the S-CSCF (Service-Call Session Control Function) downloads and uses this file when the user registers with the network.

[0077] I-CSCF (Interrogating Call Session Control Function): The first entry point of the home network for interrogating CSCF users, assigning S-CSCFs, performing route lookups, and providing inter-domain topology hiding functions.

[0078] iFC (Initial Filter Criteria): This is a part of the user subscription data stored in HSS. It is downloaded to the S-CSCF assigned to the user during user registration. iFC defines the conditions and target AS for triggering services according to different priorities. When processing user service requests, S-CSCF performs iFC matching and detection. If the triggering conditions are met, it triggers the specified AS, so that the AS can control the service according to the established business logic within the AS.

[0079] MGCF (Media Gateway Control Function): A component of the IP Multimedia Subsystem (IMS), it communicates with the Call Session Control Function (CSCF) and controls the connection of media channels within an IMS-MGW. It performs protocol conversion between the ISDN Part (ISUP) and the IMS call control protocol.

[0080] P-CSCF (Proxy Call Session Control Function): This is the unified entry point for IMS access to the network. All session messages initiated and terminated by IMS terminals must pass through P-CSCF. As a SIP proxy, P-CSCF is responsible for user authentication and IPSec management independent of the access network, network attack prevention and security protection, SIP signaling compression and decompression to save wireless network resources, user roaming control, and bearer NAT and QoS functions through PDF (Policy Decision Function).

[0081] PPR (Push-Profile-Request): The PPR message, represented by command code 305 and the setting command flag "R", is used to request an update to subscription data. The PPR message is sent from the HSS to the S-CSCF. When subscription data is modified, the HSS sends a PPR message to request an update to the user data in the S-CSCF.

[0082] PPA (Push-Profile-Answer): The message is represented by command code 305 and the clear command flag "R". It is used to respond to PPR messages, that is, to respond to the user's subscription data update request command. PPA messages are sent from S-CSCF to HSS.

[0083] S-CSCF (Serving Call Session Control Function): The core of the Serving CSCF multimedia module, which includes terminal registration and authentication, session control, and service triggering.

[0084] SMS (Short Message Service): Short messages encapsulated using the SIP protocol, possessing the same service characteristics as traditional short messages. They are initiated or received by IMS users and transmitted or forwarded through the IMS system. Users send or receive text or numeric information directly through mobile phones or other telecommunications terminals. Each short message has a character limit, generally 160 English or numeric characters, or 70 Chinese characters.

[0085] SMSC (Short Message Service Center): A crucial SMS processing center responsible for forwarding, storing, and distributing SMS messages. An SMSC is a software system based on a digital network that uses SMS center routing technology to enable the exchange of SMS messages between different networks. The SMSC is a key component of SMS services and the central foundation of the SMS transmission system. It manages SMS services such as the regular sending and receiving of passive notifications. Globally, the SMSC is an essential infrastructure for every operator because it is the core of SMS communication, providing robust support and assurance for mobile networks.

[0086] UDM (Unified Data Management): Responsible for the management of user identifiers, subscription data, authentication data, and user service element registration management (such as the AMF and SMF currently providing services to the terminal; if a user switches to a different AMF, UDM will also send a deregistration message to the old AMF, requesting the old AMF to delete the user's relevant information).

[0087] UE (User Equipment): Various user equipment that accesses the network, the most common being mobile phones, others such as SIP phones, IP phones, call centers, and generally refers to user communication equipment that can access the IMS network.

[0088] Based on an understanding of the above technical terms, the embodiments of the present invention will be explained below.

[0089] Figure 1 This is a flowchart of a short message service control method provided in an embodiment of the present invention, such as... Figure 1 As shown, this method is applied to the Service Call Session Control Function (S-CSCF) network element and includes the following steps:

[0090] Step 101: Receive a Session Initiation Protocol (SIP) message sent by the User Equipment (UE), wherein the SIP message encapsulates a short message.

[0091] Step 102: If the SIP message does not include the reply parameters of the Short Message Single Stop Initial Filtering Rule (iFC), the SIP message is forwarded to the designated network element on the server for processing or the SIP message is discarded.

[0092] The SMS service control method described in this invention can be applied to terminals, servers, etc., without limitation. The terminal implementation device can be an electronic device such as a smartphone, laptop, tablet, desktop computer, personal digital assistant (PDA), and wearable device. The server can be an independent server, a server cluster, or a server that provides cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks, or big data and artificial intelligence platforms, etc., without limitation.

[0093] The following is combined with Figure 1 The specific implementation steps of a short message service control method provided in the embodiments of the present invention will be described in detail.

[0094] In step 101, a Session Initiation Protocol (SIP) message sent by the User Equipment (UE) is received, wherein the SIP message encapsulates a short message.

[0095] In this step, the Service Call Session Control Function (S-CSCF) network element receives a Session Initiation Protocol (SIP) message sent by the User Equipment (UE). This SIP message encapsulates a Short Message Service (SMS). The encapsulation process of encapsulating the SMS message into the SIP message is well-known to those skilled in the art and will not be described in detail here.

[0096] Specifically, it can receive Session Initiation Protocol (SIP) messages sent by the User Equipment (UE) through the Edge Access Control (BAC) or the Proxy Call Session Control Function (P-CSCF) network element.

[0097] The key parameters carried in a short message include, but are not limited to, the following:

[0098] Request URI: Sender eSMSC PSI

[0099] To: Sender eSMSC PSI;

[0100] From / P-Preferred-Identity: Sender's tel URI or SIP URI;

[0101] Content-Type: application / vnd.3gpp.sms (indicating SMS service);

[0102] Message body: GSM MAP encapsulation format;

[0103] In step 102, if the SIP message does not include a reply parameter for Short Message Single Stop iFC, the SIP message is forwarded to a designated network element on the server for processing or the SIP message is discarded.

[0104] The "Reply" parameter of "Short Message Single Stop iFC" can be the string In-Reply-To. The line containing In-Reply-To may include information such as Call-Id from MESSAGE(RP-DATA), or it may not include any information and only contain the string In-Reply-To. Of course, in actual applications, it can also be other parameters with the same or similar functions, and this embodiment is not limited to this.

[0105] In this step, the network element configured on the server side can be a Media Gateway Control Function (MGCF) network element, etc. Since MGCF does not support message requests, it will return error or unsupported information, thereby achieving the purpose of controlling the short message to stop.

[0106] In this embodiment of the invention, the S-CSCF network element receives a Session Initiation Protocol (SIP) message sent by a User Equipment (UE), which encapsulates a short message. If the SIP message does not include a "response" parameter for "Short Message Single Stop iFC," the SIP message is forwarded to a designated network element on the server side for processing or discarded. In other words, in this embodiment, by determining the "response" parameter for "Short Message Single Stop iFC" through the S-CSCF, the single stop of short messages is no longer controlled by the eSMSC, but rather by the triggering conditions preset by the iFC through the S-CSCF. This is cleverly applied within the "Short Message Single Stop iFC" triggering rules, without adding extra investment or changing the network architecture, thereby achieving the goal of real-time single stop of short messages.

[0107] Optionally, in another embodiment, based on the above embodiments, the method may further include:

[0108] 1) Determine whether the SIP message includes a short message single stop iFC reply parameter, the reply parameter including: In-Reply-To.

[0109] The judgment process in this embodiment includes: first, matching the SIP message with the preset short message single stop initial filtering rule iFC; when the matching result meets the triggering condition of short message single stop iFC, identifying that the SIP message does not contain the reply parameter of short message single stop iFC.

[0110] In this embodiment of the invention, when the S-CSCF network element receives a SIP message, it first determines whether the SIP message sent by the UE includes a short message stop reply parameter. If it does not include a short message stop reply parameter, the SIP message is forwarded to a designated network element (such as MGCF) on the server side for processing or the SIP message is discarded. The MGCF does not support MESSAGE requests and will reply with an error or unsupported response message to the received SIP message. It will not send the SIP message to the called party normally, thereby achieving the purpose of controlling short message stop.

[0111] Optionally, in another embodiment, based on the above embodiments, the method includes: receiving a request from the Home Subscriber Server (HSS) / or UDM for the user to update their subscription short message single stop (iFC); updating the user's stored iFC data according to the request; and sending a response to the HSS regarding the updated iFC data.

[0112] In this embodiment, when a UE is already registered on the network, and some UE numbers require SMS service suspension, the "Short Message Service Suspension iFC" service is subscribed to on the HSS and / or UDM. When the registered user's subscription data changes, the HSS and / or UDM send a PPR request to the S-CSCF network element, requesting an update of the user's subscription data for that UE in the S-CSCF network element. The S-CSCF network element updates the user's subscription data for that UE according to the PPR request. After the update, the S-CSCF network element sends a PPA response to the HSS and / or UDM. This PPA is used to respond to the PPR message, i.e., to respond to the user subscription data update request command. The PPA message is sent from the S-CSCF network element to the HSS and / or UDM. Specifically, as follows... Figure 2 The diagram shows a flowchart illustrating the interaction between the HSS and S-CSCF when updating user subscription data, as provided in this embodiment of the invention. It should be noted that this embodiment uses the interaction between the S-CSCF network element and the HSS as an example, but in practical applications, it is not limited to this.

[0113] Optionally, in another embodiment, based on the above embodiment, before the S-CSCF receives the Session Initiation Protocol (SIP) message sent by the User Equipment (UE), the method may further include: pre-setting a Short Message Single Stop (iFC) in the Serving Call Session Control Function (S-CSCF) network element, and a triggering condition for the iFC, wherein the triggering condition includes: the SIP message header field does not include a reply parameter for the iFC, and the reply parameter includes: In-Reply-To.

[0114] In this embodiment, by planning a "Short Message Single Stop iFC", the single stop of short messages is no longer controlled by the eSMSC, but by the trigger conditions preset by the iFC through the S-CSCF. The specific steps are as follows:

[0115] 1) Set "Short Message Single Stop iFC". The iFC trigger condition is: the SIP header field does not include In-Reply-To; that is, the SIP header field must include In-Reply-To in order to send short messages normally.

[0116] 2) UEs requiring SMS service suspension subscribe to "SMS Suspension iFC". When certain UE numbers require SMS service suspension, they subscribe to "SMS Suspension iFC". That is, the UE obtains its iFC information from the Home Subscriber Server (HSS) and / or Unified Data Management (UDM) network element through the P-CSCF, S-CSCF, and I-CSCF network elements. This iFC information includes the SMS suspension iFC, and the SMS suspension iFC is saved to the S-CSCF network element. Afterwards, the UE completes the registration process through initial registration, secondary registration, and third-party registration. The specific registration process is well known to those skilled in the art and will not be described in detail here.

[0117] In other words, in this embodiment of the invention, "Short Message Single Stop iFC" is first set, and the iFC triggering condition is: the SIP header field does not include In-Reply-To; only when the SIP header field includes In-Reply-To can short messages be sent normally.

[0118] Subsequently, UEs that need to suspend SMS services individually will sign up for "Short Message Service Suspension iFC". In other words, when certain UE numbers of UEs already registered on the network need to suspend SMS services individually, they will sign up for "Short Message Service Suspension iFC" on the HSS and / or UDM.

[0119] Finally, UEs subscribed to "Single-Terminal Short Message Service (iFC)" fail to send SMS messages. When a UE sends a SIP Message to the S-CSCF network element via BAC / P-CSCF, the SIP Message does not include In-Reply-To. The S-CSCF pre-stores the trigger condition for "Single-Terminal Short Message Service (iFC)" for this UE number, which is that the SIP header field does not include In-Reply-To. Therefore, when the S-CSCF network element receives the SIP Message sent by the UE, it first checks whether the header field of the SIP Message includes In-Reply-To. If it does not include In-Reply-To, it forwards the SIP Message sent by the UE to the designated network element on the server side (such as the MGCF network element). In other words, UEs subscribed to "Single-Terminal Short Message Service (iFC)" will fail to send SMS messages, thus achieving the purpose of real-time single-terminal suspension of SMS service.

[0120] Please also see Figure 3 This diagram illustrates an application example of a short message service control method provided in this invention, showcasing the short message (SMS) initiation process, specifically including:

[0121] Step 301: The UE sends a SIP Message encapsulated with a short message to the S-CSC F network element via BAC / P-CSCF, carrying the following key parameters:

[0122] Request URI: Sender's eSMSC PSI;

[0123] To: Sender eSMSC PSI;

[0124] From / P-Asserted-Identity: Sender's tel URI or SIP URI;

[0125] Content-Type: application / vnd.3gpp.sms (indicating SMS service);

[0126] Message body: GSM MAP encapsulation format.

[0127] It should be noted that the SIP Message does not include In-Reply-To, and the trigger condition for the UE's "Short Message Single Stop iFC" to be pre-stored on the S-CSCF network element is that the SIP header field does not include In-Reply-To.

[0128] Step 302: The S-CSCF network element determines whether the SIP Message includes the In-Reply-To parameter of the short message single-stop iFC.

[0129] Step 303: If it is determined that the SIP Message does not include the In-Reply-To reply parameter of the Short Message Single Stop iFC, the SIP Message is forwarded to the designated network element (such as MGCF) on the server side.

[0130] Step 304: The MGCF replies that it does not support SIP messages; or the MGCF reports an error or discards the SIP message.

[0131] In this embodiment of the invention, since the MGCF does not support SIP Message messages, it cannot send the short message received from the UE to the called side, thereby achieving the purpose of controlling the single-stop short message.

[0132] Please also see Figure 4 This is another flowchart of a short message service control method provided by an embodiment of the present invention. The method is used for a user equipment (UE) and includes:

[0133] Step 401: Encapsulate the short message into a SIP message.

[0134] In this step, short messages encapsulated using the SIP protocol and possessing the same business characteristics as traditional short messages are initiated or received by IMS users and transmitted or forwarded through the IMS system. The encapsulation process is well-known to those skilled in the art and will not be elaborated upon here.

[0135] Step 402: Send the SIP message to the S-CSCF network element so that when the S-CSCF network element does not include the short message single stop iFC reply parameter in the SIP message, it can forward the SIP message to the designated network element on the server side for processing or discard the SIP message.

[0136] In this step, the SIP message is sent to the S-CSCF network element through the Edge Access Control (BAC) or the Proxy Call Session Control (P-CSCF) network element; the SIP message does not include the reply parameters for Short Message Single Stop (iFC), and the reply parameters include: In-Reply-To.

[0137] In this embodiment of the invention, the short message is first encapsulated into a SIP message; then, the SIP message is sent to the S-CSCF network element, so that the S-CSCF network element can perform different control processing depending on whether the SIP message includes the short message single-stop iFC reply parameter. That is, if the SIP message does not include the short message single-stop iFC reply parameter, the SIP message is forwarded to a designated network element on the server side for processing or discarded. In other words, when the S-CSCF network element receives a SIP message sent by the UE, it first checks whether the SIP message includes the short message single-stop iFC reply parameter, such as In-Reply-To; if it does not include it, the SIP message is forwarded to a designated network element on the server side for processing or discarded, thereby achieving the purpose of controlling short message single-stop.

[0138] Optionally, in another embodiment, based on the above embodiment, before encapsulating the short message into a SIP message, the method further includes: setting up a short message single-stop iFC in advance on the Home Subscriber Server (HSS) and / or Unified Data Management Function (UDM) network element, and the triggering condition of the short message single-stop iFC, wherein the triggering condition includes: the SIP message header field does not include the reply parameter of the short message single-stop iFC, and the reply parameter includes: In-Reply-To.

[0139] Please also see Figure 5 The flowchart below shows another application example of a short message service control method provided by an embodiment of the present invention, including:

[0140] Step 501: Pre-configure the Short Message Single Stop iFC in the Service Call Session Control Function (S-CSCF) network element, Home Subscriber Server (HSS) and / or Unified Data Management Function (UDM) network element, and the triggering conditions for the Short Message Single Stop iFC. The triggering conditions include: the SIP message header field does not include the reply parameter of the Short Message Single Stop iFC. The reply parameter includes: In-Reply-To. That is, the iFC triggering condition is: the SIP header field does not include In-Reply-To.

[0141] Step 502: When the subscription data of the registered user equipment (UE) changes, the home subscriber server (HSS) sends a request to the S-CSCF network element to update the UE's subscription short message service (SMSS) and stop the iFC.

[0142] Step 503: The S-CSCF network element updates the stored UE-subscribed short message single stop iFC data according to the request.

[0143] Step 504: The S-CSCF network element sends a response to the HSS regarding the user's update of the subscribed short message single stop iFC data.

[0144] Step 505: The UE encapsulates the short message into a SIP message.

[0145] Step 506: The UE sends the SIP message to the S-CSCF network element through the Edge Access Control (BAC) or the Proxy Call Session Control (P-CSCF) network element.

[0146] Step 507: The S-CSCF network element determines whether the SIP message includes a short message single stop iFC reply parameter, the reply parameter including: In-Reply-To; if not, proceed to step 508.

[0147] The judgment process is to match the SIP message with the preset short message single-stop initial filtering rule iFC.

[0148] Step 508: When the S-CSCF network element does not include the short message single stop iFC reply parameter in the SIP message, it forwards the SIP message to the designated network element on the server side. In this embodiment, the designated network element is MGCF, but in actual applications, it is not limited to this.

[0149] Step 509: The MGCF replies to the S-CSCF network element that it does not support SIP Messag messages; or the MGCF reports an error or discards the SIP message.

[0150] In this embodiment, a trigger condition for "Short Message Single Stop iFC" is pre-set on the S-CSCF network element. That is, the header field of the SIP message does not include the reply parameter of Short Message Single Stop iFC. For example, the reply parameter includes In-Reply-To. Therefore, the S-CSCF network element will judge the SIP message sent by the UE and determine whether the SIP message includes the reply parameter of Short Message Single Stop iFC. The judgment process is to match the SIP message with the preset Short Message Single Stop iFC. When the matching result meets the preset trigger condition of Short Message Single Stop iFC, the SIP message is forwarded to the set network element on the server for processing or the SIP message is discarded. That is, the SIP message will not be sent to the called side normally, thus achieving the purpose of real-time single stop of short message service.

[0151] The present invention involves setting a response parameter for "Single Stop Short Message iFC" and cleverly incorporating the In-Reply-To response parameter within the "Single Stop Short Message iFC" triggering rule. The UE sends a SIP message encapsulated with a short message to the S-CSCF network element via the Edge Access Control (BAC) or the Proxy Call Session Control Function (P-CSCF) network element. The S-CSCF network element, after evaluation, determines that the SIP message encapsulated with the short message does not include the In-Reply-To response parameter. Therefore, the SIP message is sent to the designated network element (e.g., MGCF), thus achieving the purpose of single stop short message communication.

[0152] It should be noted that the triggering condition for short message single-stop iFC in this embodiment of the invention is: the SIP header field does not include the reply parameter In-Reply-To. Here, the reply parameter In-Reply-To is a parameter recognized by the S-CSCF network element (normally, if other string parameters are used, the S-CSCF network element may not be able to recognize them, and the S-CSCF network element will report an error. When a large number of UEs stop short messages, a large number of error messages will be generated, which may cause network problems or even congestion). In this embodiment, when the UE sends a SIPMessage to the S-CSCF network element, the S-CSCF network element immediately matches the received SIPMessage with the pre-stored short message single-stop iFC rules. When the S-CSCF network element recognizes that the SIPMessage header field does not include In-Reply-To, it discards the SIPMessage or transfers it to other network element devices (such as MGCF) for processing according to the set short message single-stop iFC triggering rules, thereby achieving the purpose of controlling short message single-stop.

[0153] For ease of understanding, please refer to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0154] First, on the S-CSCF, HSS, and / or UDM network elements, set the short message single-stop iFC=4444. Based on the iFC triggering rules for short message services based on the IMS network, add triggering conditions, as shown in the bold italicized portion of the following code segment. The iFC triggering rules and settings for short message services based on the IMS network are well-known to those skilled in the art and will not be elaborated upon here.

[0155]

[0156] or

[0157]

[0158] As can be seen from the above code segment, the triggering condition can be understood as: the SIP header field contains In-Reply-To, and the S-CSCF network element forwards the short message to the eSMSC. In reality, the SIPMESSAGE sent by the UE and forwarded by the P-CSCF network element to the S-CSCF network element does not contain In-Reply-To. This achieves the goal of the S-CSCF network element not forwarding the short message to the eSMSC, but instead sending it to a designated network element on the server side (such as the MGCF) for processing or discarding the SIP message.

[0159] In other words, the triggering condition can also be understood as: the SIP header field does not include In-Reply-To, and the S-CSCF network element sends the short message to a designated network element (such as MGCF) on the server side for processing or discarding the SIP message.

[0160] Secondly, UE_A signed iFC=4444.

[0161] Next, UE_A sends a short message, that is, the UE encapsulates the short message in a SIP MESSAGE and sends it to the S-CSCF via BAC / P-CS CF.

[0162] Finally, the S-CSCF determines that the SIP MESSAGE header field does not contain the reply parameter In-Reply-To, which does not meet the triggering rule iFC=4444. Therefore, the calling S-CSCF network element does not forward the SIP MESSAGE to the eSMSC. Instead, it routes the request containing the short message SIP MESSAGE to the MGCF through DNS preset resolution. However, the MGCF does not support the SIP MESSAGE request. That is, the MGCF replies to the S-CSCF network element with an unsupported message, or reports an error or discards the SIP MESSAGE, thus achieving the purpose of not being able to send short messages normally (short message service is suspended in real time).

[0163] It should be noted that, in this embodiment of the invention, in order to better achieve the technical effect of single-stop short message service, UE_A can simultaneously / sequentially delete short message service iFC and add a subscription to "single-stop short message iFC".

[0164] This invention is based on iFC, which sets up "Short Message Single Stop iFC" and cleverly uses the reply parameter In-Reply-To within the triggering rule of "Short Message Single Stop iFC". Since the reply parameter In-Reply-To is originally a parameter in the Message (RP_ACK) sent by the eSMSC to the S-CSCF, the reply parameter In-Reply-To is recognized by the S-CSCF. Therefore, without increasing additional investment or changing the network architecture, the purpose of real-time single stop of short messages is achieved.

[0165] It should be noted that, for the sake of simplicity, the method embodiments are all described as a series of actions. However, those skilled in the art should understand that this disclosure is not limited to the described order of actions, because according to the present invention, some steps can be performed in other orders or simultaneously.
