Description

Method for realizing mobile data service by IP user based on IP access

Technical field

The present invention relates to the field of network communication technologies, and in particular, to a method for implementing mobile data services by an IP user based on IP (Internet Protocol) access.

Background technique

With the rise and development of various IP access technologies, how to provide existing mobile network services to IP users based on IP access, and make existing mobile network services become services of IP users, has become 3GPP (The 3rd Generation Partnership Project, a research project of the Standardization Organization.

Due to the increasing popularity of networks based on IP access, such as WLAN (Wirless Local)

Area Network (WLAN), NGN (Next Generation Network), etc., for various IP user equipment such as IP terminals, or multimode terminals that support both IP access and mobile network access methods, such as WLAN and WCDMA/GSM (Wideband Code Division Multiple Access/Global System for Mobile Communications) multimode terminal, how to reuse existing mobile network SMS/MMS (Short Messaging Service/ Multimedia Message System (short message service/multimedia short message) service function entities and protocols, and access to the mobile core network through the IP access network, is also a common concern of operators.

Existing mobile network services such as SMS and MMS are considered to be one of the most important and widely used services in the current mobile network. The network frame for IP users to implement short message service proposed by 3GPP is shown in Figure 1.

In Figure 1, SME (Small Message Entity), SM-SC (Short Message Service Centre), GMSC/SMS-IWMSC (Gateway Mobile Switching Center/Short Message Service InterWorking MSG, gateway mobile Switching Center/Short Message Gateway), HSS/HLR (Home Subscriber Server/Home Location Register), CGF/CDF (Charging Gateway Function/Charging Data Function) OCS (Online Charging System) is an existing mobile network implementing SMS The functional entity of the business.

The SM-SC is used to store short messages; the GMSC is used to query the HSS/HLR for routing information when the mobile user receives the short message; and the SMS-IWMSC is used to check whether the short message is allowed to be sent to the home SM-SC in the case of the mobile user roaming. . The short message centers applied in the mobile network are all three devices integrating SM-SC, GMSC and SMS-IWMSC, and the three functional entities are not implemented as separate physical devices, so in the following, the short message center It represents the three integrated network devices of SM-SC:, GMSC and SMS-IWMSC.

The HSS/HLR is used to store data information of mobile users, including routing information. The CGF/CDF is used to collect and process the billing information of the user's offline billing, and then transmitted to the billing center. The OCS is used to collect and process the mobile subscriber online meter. The bill information is then passed to the billing center.

The IP-Message-GW in Figure 1 is a new network entity. The network entity implements IP user equipment and GMSC/SMS by interworking the IP network message protocol with the existing WCDMA/GSM network short message protocol. Communication between IWMSCs.

When an IP user uses the short message service, it must first register with the IP-Message-GW (IP Message Service Gateway), the IP-Message-GW notifies the HSS that the IP user is registered and the IP-Message-GW address, and the HSS saves the IP user's The status is IP Connected and stores the IP user's address and the address of its registered IP-SM-GW.

The current specification proposes a method for establishing a secure connection between multiple IP user equipments and IP-Message-GW, including: a security architecture based on GAA (Generic Authorization Architecture), based on IMS (IP Multimedia Subsystem, IP Multimedia) The network architecture of the subsystem and the tunnel-based approach to establish a secure connection between the IP user equipment and the IP-Message-GW.

For the secure connection between the IP user equipment and the IP-Message-GW based on the GAA-based security architecture and the tunnel-based method, the process of registering the IP user equipment to the IP-Message-GW is shown in Figure 2.

In Figure 2, in step 1, the IP user equipment establishes an IP connection.

Step 2: After successfully establishing an IP connection, the IP user equipment sends a secure UE Registration Req message to the IP-Message-GW, where the message includes the identity information of the IP user, such as a NAI (Network Access Identifier). )Wait. In this step, The IP user equipment can use the GAA architecture or the tunneling method defined by the 3GPP IP access method to ensure the secure transmission of the UE Registration Req message.

Go to step 3. IP-Message-GW obtains the IMSI (International Mobile Subscriber Identification Number) of the IP user from the usemame (user name) part of the NAI, and the IP-Message-GW passes the IP-IWF-Register Req. The message registers the IPI's IMSI in the HLR/HSS.

Go to step 4. The HLR/HSS stores the IP-Message-GW address registered by the IP user, and sets the IP user's status to IP connecte IP connection. In addition, the HLR/HSS notifies the presence (user presence status) server, IP. The user's status is IP connected.

Go to step 5. After the registration is successful, the HLR/HSS is in the IP-IWF-Register Res message.

IP-Message-GW returns the MSISDN (Station International ISDN Number) of the IP user.

Go to step 6. The IP-Message-GW stores the association between the MSISDN and the IP address of the IP user in the local database, and returns a UE Registration Res message to the IP user equipment.

In the above process, if the registration process times out, the IP user equipment can re-initiate the registration process by using steps 2 to 6.

After the IP user is successfully registered in the IP-Message-GW by using the registration process in FIG. 2, the process of the IP user initiating the short message flow is as shown in FIG. 3.

In Figure 3, in step 1, the IP user registers with the IP-Message-GW.

Go to step 2. The IP user equipment submits a short message to the IP-Message-GW.

Go to step 3. The IP-Message-GW parses the short message, and extracts the IP address of the IP user and the MSISDN association relationship of the IP user from the local database, and uses the standard MAP (Mobile Application Part) for the parsed short message. Part) Signaling is forwarded to the SMS-IWMSC.

Go to step 4. The SMS-IWMSC forwards the short message to the SM-SC.

Go to step 5. The SM-SC sends a short message submission report to the SMS-IWMSC.

Go to step 6, the SMS-IWMSC sends a short message submission report to the IP-Message-GW. Go to step 7, the IP-Message-GW sends a short message submission report to the IP user equipment. Establishing IP user equipment and IP-Message-GW for IMS-based network architecture In the case of full connection, the processing flow for the IP user to register with the IP-Message-GW is as shown in FIG. 4. In Figure 4, in step 1, the IP user equipment establishes an IP connection.

Go to step 2. After the IP user device successfully establishes an IP connection, it registers with the S-CSCF (Service CSCF) according to the IMS registration process. In the IMS registration process, the functional entities such as I-CSCF (Interworking CSCF) and P-CSCF (Proxy CSCF) and the messages transmitted between many S-CSCFs and HSSs are involved. Here, for the sake of cleanliness, no Listed.

Go to step 3. The S-CSCF checks the filter (filter) information from the HLR/HSS in the IMS registration process.

Go to step 4. After the IMS registration is successful, the S-CSCF notifies the IP-Message-GW IP user that the IP user has registered to the IMS domain according to the filter information.

Go to step 5. The IP-Message-GW sends an IP-IWF-Register Req message to the HLR/HSS, and registers the IP user ID and its own address information in the HLR/HSS.

Go to step 6. The HLR/HSS stores the IP-Message-GW and the IP user's address information, and then returns the IP-IWF-Register Res message to the IP-Message-GW.

Go to step 7. The IP-Message-GW returns a SIP 200 OK message to the S-CSCF.

In the above process, if the IP-Message-GW address information of each IP user is pre-configured in the HLR/HSS, the IP-Message-GW does not need to register its own address information with the HLR/HSS. That is, steps 5 and 6 can be omitted.

After the IP user equipment is registered in the IP-Message-GW by using the registration procedure in FIG. 4, the processing procedure for the IP user to initiate the short message flow is as shown in FIG. 5.

In Figure 5, in step 1, the IP user equipment is registered in the S-CSCF according to the IMS registration procedure.

Go to step 2. The IP user sends a short message to the S-CSCF based on the SIP (Session Initiation Protocol) MESSAGE mode.

Go to step 3. The S-CSCF forwards the short message to the IP-Message-GW according to the filter information. Go to step 4. The IP-Message-GW returns a SIP 202 receive message to the S-CSCF, indicating that the short message has been received.

Go to step 5. The S-CSCF forwards the SIP 202 to the IP user equipment to receive the message.

Go to step 6, IP-Message-GW parses out the short message, and uses the parsed short message. Standard MAP signaling is forwarded to the SMS-IWMSC. SM-SC address information can be obtained from

The MESSAGE R-URI (Requested-Unique Resource Identifier) part or the message body part of the short message is parsed.

Go to step 7. The SMS-IWMSC forwards the short message to the SM-SC.

Go to step 8. The SM-SC sends a short message submission report to the SMS-IWMSC.

Go to step 9. The SMS-IWMSC sends a short message submission report to the IP-Message-GW. According to the 10, IP-Message-GW uses SIP MESSAGE to send a short message to the S-CSCF to submit a report.

Go to step 11. The S-CSCF uses SEP MESSAGE to send a short message to the IP user equipment to submit a report.

In step 12, the IP user equipment responds to the received short message by using the 200 OK message to submit the report.

To step 13, the 200 OK response message is forwarded to the IP-Message-GW via the S-CSCF. It can be seen from the above descriptions in conjunction with FIG. 1 to FIG. 5 that although the specification of the 3GPP research defines the process of IP user registration in the IP-Message-GW and the process of the IP user initiating the short message flow, there is no IP user. Signed IP-based data services, such as IP/based SMS/MMS services; or IP users subscribe to IP-based data services, but they want to sign some IP-based data services. Shielding, that is, the IP service-based data service of the IP user is disabled; or the operator wants to limit the IP service-based data service capability of some IP users for certain security reasons, however According to the current 3GPP definition of the IP service-based data service process, that is, the IP user registration process and the service use process, such as the IP user initiated short message processing process, do not authorize the IP user's service capability. So that IP users can use IP access-based data services without restrictions, but IP users and operators cannot Line control, is not conducive to operators and users of IP-based IP access data services management.

9 is a flow chart of still another embodiment of a method for implementing a mobile data service by an IP access-based IP user according to the present invention.

The core of the present invention is: setting the authorization information of the IP data of the IP user. When the IP user needs to perform the mobile data service, the network side performs the mobile data service authorization information of the IP user to the IP user. Authorize the mobile data service and provide mobile data services for the IP user when the authorization is successful.

The technical solution provided by the present invention will be further described below based on the core idea of the present invention.

When the IP user needs to use the mobile data service, the present invention authorizes the IP user, and the process of issuing the IP right can be implemented by an IP service gateway such as an IP message service gateway, or can be implemented by the S-CSCF. The network side only allows authorized IP users to use mobile data services. For IP users whose authorization fails, they are not allowed to use mobile data services. This prevents IP users from using mobile data services without any restrictions, and protects IP users. And operator security management of mobile data services.

The IP users in the present invention include: IP users accessing the network by means of IP access, IP user equipment such as IP terminals, or multimode terminals supporting both IP access mode and mobile network access mode, such as WLAN and WCDMA/ GSM multimode terminal, etc.

The mobile data service in the present invention includes: SMS/MMS service.

In view of the fact that the SMS/MMS service is the most important and widely used service in the current mobile network, the technical solution provided by the present invention will be described in detail below by taking the implementation method of the message service as an example.

The invention first needs to set the authorization information of the IP user mobile data service. Since the message service implementation method message is in the following embodiment, the authorization information of the mobile data service here is the authorization information of the message service. The authorization information of the message service can be set in the HLR/HSS, or can be set in other network devices such as DSMP (Data Service Management Platform). The authorization information of the IP user message service includes: the subscription information of the IP user and the authorization information of the IP user message service set by the operator.

After the authorization information of the BP user message service is set, the network side, such as the IP message service gateway and the S-CSCF, can use different timings to initiate the authorization process of the IP user message service, such as initiating IP when the IP user registers the message service. The authorization process of the user message service, and the authorization process of the IP user message service is initiated when the IP user performs the message service.

When an IP user needs to register a message service and an IP user needs to register to the IP-Message-GW, the IP-Message-GW may initiate an authorization process for the IP user message service to the authorized party when receiving the registration request of the IP user. The authorized party starts to check the subscription information of the IP user and the authorization information of the IP user message service set by the operator. If the authorization of the IP service of the IP user fails, the IP-Message-GW rejects the IP user according to the information of the authorization failure. If the authorization of the IP service of the IP user is successful, the IP-Message-GW allows the registration of the IP user according to the information of the authorization success, and continues the registration process of the IP user, so that the network side can provide the message service.

When an IP user registers with the IP-Message-GW, the authorization process is initiated by the IP-Message-GW, and the authorization process for the IP user by the authorized party mainly has the following two methods:

Method 1: The IP-Message-GW initiates the authorization process of the IP user message service, and the HLR/HSS implements the authorization process of the IP user. The implementation process is shown in FIG. 6.

In FIG. 6, in step 1, the IP user equipment establishes a secure connection between the IP user equipment and the IP-Message-GW based on the GAA-based security framework and the tunnel-based manner.

Step 2: After successfully establishing an IP connection, the IP user equipment sends a secure UE Registration Req message to the IP-Message-GW, where the message includes the identity information of the IP user, such as a NAI (Network Access Identifier). In this step, the IP user equipment can use the GAA architecture or the tunneling method defined by the 3GPP IP access method to ensure the secure transmission of the UE Registration Req message.

This method implements the authorization process of the IP user by the HLR/HSS. Therefore, step 3 can be omitted and directly to step 4.

In step 4, the IP-Message-GW sends an IP-IWF-Register Req message to the HLR/HSS. The HLR/HSS connects to the IP user based on the IP user's authorization information. The incoming message service capability is checked, such as checking whether the user has subscribed to the message service or whether the operator has restricted the use of the message service, and determines whether the IP user can use the short message service, if the HLR/HSS is determining the When the IP user authorization is successful, the IP user is allowed to use the message service.

In this method, the process in which the IP-Message-GW initiates the authorization process to the authorized party may be considered as follows: The IP-Message-GW sends an IP-IWF-Register Req message to the HLR/HSS.

Go to step 5. The HLR/HSS stores the IP-Message-GW address registered by the IP user, and sets the IP user's status to IP connected. In addition, the HLR/HSS notifies the Presence server that the IP user's status is IP. Connected

Go to step 6. The HLR/HSS returns the MSISDN of the IP user to the IP-Message-GW in the IP-IWF-Register Res message.

Go to step 7. The IP-Message-GW stores the association relationship between the MSISDN and the IP address of the IP user in the local database, and returns a UE Registration Res message to the IP user equipment.

In step 4, if the HLR/HSS determines that the IP user authorization fails, the IP user should be prohibited from using the message service, and the HLR/HSS rejects the IP-Message-GW message service registration request, and the IP-Message-GW rejects the IP user. Message service registration request.

In the above process, the HLR/HSS may determine that the IP user wishes to use the message service according to the address information of the IP-Message-GW that initiates the authorization request. The HLR/HSS can also determine that the IP user wants to use other mobile data services according to different service gateway addresses, so that the HLR/HSS can perform different mobile data service authorizations for various mobile data service capabilities of IP users.

Method 2: The IP-Message-GW initiates an authorization process for the IP user message service, and other authorized parties implement the authorization process of the IP user.

The method is basically the same as the above description of each step in FIG. 6, but after the end of step 2, step 3 is required, and the IP-Message-GW needs to send a message service authorization request to other authorized parties, requesting other authorized parties to IP. The user's message service capability is checked, and other authorized parties determine whether the IP user can use the message service, such as the DSMP (Data Service Management Platform) of the IP-Message-GW and the centralized storage management user data service capability in the network. Database interaction, IP-Message-GW to DSMP 00554

-14- Provides identification information of the IP user, such as IMSI. After checking the message service capability of the IP user, the DSMP returns the authorization result to the IP-Message-GW. The IP-Message-GW determines that the authorization result returned by the DSMP is the authorization succeeded. When, in step 4, the IP-Message-GW accepts the registration request of the IP user, sends an IP-IWF-Register Req message to the HLR7HSS, and continues the subsequent steps; the IP-Message-GW determines that the authorization result returned by the DSMP is an authorization failure. At this time, the registration request of the IP user is rejected, so that the IP service is not provided for the IP user.

In this method, the DSMP can determine that the IP user wants to use the message service according to the address information of the IP-Message-GW that initiates the authorization request, and the DSMP can also determine that the IP user wants to use other data services according to different service gateway addresses. Therefore, DSMP can perform different mobile data service authorization for various mobile data service capabilities of IP users.

When an IP user establishes a secure connection with the IP-Message-GW based on the IMS network architecture, and the IP user registers with the IP-Message-GW based on the IMS registration procedure, the IP service message authorization process may be performed by the IP-Message-GW. Initiation, the process is similar to steps 3 to 6 shown in Figure 6, and may also be initiated by the S-CSCF. When the authorization process is initiated by the S-CSCF to implement the authorization process of the IP service of the IP user, the specific implementation process is as shown in FIG. 7.

In Figure 7, in step 1, the IP user establishes a secure connection with the IP-Message-GW based on the IMS-based network architecture.

After step 2, the IP user equipment successfully establishes an IP connection and registers with the S-CSCF according to the IMS registration process. In the IMS registration process, the functional entities such as I-CSCF and P-CSCF and the messages transmitted between many S-CSCFs and HSSs are involved, which are not listed here for the sake of brevity.

Going to step 3, the S-CSCF checks the filter information from the HLR/HSS in the IMS registration process.

Going to step 4, the S-CSCF initiates a service authorization information flow for the IP user, the S-CSCF obtains the message service information of the IP user, and the S-CSCF performs authorization according to the message service authorization information of the IP user, when the IP user is in the IMS. The registration is successful, and the S-CSCF allows the IP user to use the message service when determining that the IP user authorization is successful.

Go to step 5, the S-CSCF notifies the SIP registration message according to the filter information. The IP-Message-GW IP user has been registered to the IMS domain.

Go to step 6. The IP-Message-GW sends an IP-IWF-Register Req message to the HLR/HSS, and registers the IP user ID and its own address information in the HLR/HSS.

Go to step 7. The HLR/HSS stores the IP-Message-GW and the IP user's address information, and then returns the IP-IWF-Register Res message to the IP-Message-GW.

Go to step 8. The IP-Message-GW returns a SIP 200 OK message to the S-CSCF.

In step 4, the S-CSCF does not initiate a registration message to the IP-Message-GW when it determines that the IP service's message service authorization fails and does not support the message type service, so that the IP user cannot register in the IP-Message-GW. Therefore, IP users cannot use the message service.

The method for obtaining the IP user message service authorization information by the S-CSCF may be: the IP user message service authorization information downloaded by the S-CSCF from the HLR/HSS during the interaction between the IP user and the HLR/HSS. .

In the above description of FIG. 7, the authorization process for the IP service of the IP user may also be implemented by other authorized parties. For example, in step 4, the S-CSCF may also send a message service authorization request of the IP user to the DSMP. The DSMP authorizes the IP service message service according to the stored IP user message service authorization information and the IP user's message service authorization request, and returns the authorization success or failure information to the S-CSCF, and the S-CSCF receives the authorization. When successful information is allowed, the IP user is allowed to use the message service, go to step 5, and continue with the subsequent steps. When the S-CSCF receives the information of the authorization failure, the S-CSCF does not initiate a registration message to the IP-Message-GW, so that the IP user cannot register with the IP-Message-GW.

When the IP user registers with the IP-Message-GW based on the IMS registration procedure, the S-CSCF initiates the authorization process and rejects the IP user registration to the IP-Message-GW. When the IP user needs to initiate a message through the IP-Message-GW. When the service is requested, the S-CSCF may check that the IP user has not registered to the IP-Message-GW and reject the IP service of the IP user. The S-CSCF may also forward the IP service message service request to the IP- Message-GW, when the IP-Message-GW checks that the IP user has not registered, the IP-Message-GW rejects the IP service user's message service request. This prevents IP users from using messaging services.

To implement IP user message service authorization in the process of IP user performing message service, When receiving the message service request of the IP user, the IP-Message-GW initiates the authorization process of the message service, and the network side starts to check the subscription information of the IP user and the authorization information of the CP user message service set by the operator, if the IP If the user's message service authorization fails, the IP-Message-GW rejects the message service request of the IP user. If the IP service's message service authorization is successful, the IP-Message-GW performs the message service flow of the IP user, and the network side can Provide a message-like business for it.

There are two methods for the IP user to send a message service request to the IP-Message-GW, the authorization process initiated by the IP-Message-GW, and the authorization process for the IP user:

Method 1: The IP-Message-GW initiates the authorization process of the IP service message service, and the IP-Message-GW implements the authorization of the IP service message service. The specific implementation process is shown in Figure 8.

In Figure 8, in step 1, the IP user successfully registers in the IP-Message-GW.

Go to step 3. The IP-Message-GW obtains the message service authorization information of the IP user, and authorizes the message service initiated by the IP user. The IP-Message-GW determines whether the IP service can use the message service, such as checking whether the IP user has subscribed to the message service or whether the operator has restricted the use of the IP service message service.

When the IP-Message-GW determines that the data service authorization of the IP user is successful, go to step 4. In step 4, the IP-Message-GW parses the short message, and extracts the IP address of the IP user and the MSISDN association relationship of the IP user from the local database, and forwards the parsed short message to the SMS-IWMSC using standard MAP signaling. .

Go to step 5. The SMS-IWMSC forwards the short message to the SM-SC.

Go to step 6. The SM-SC sends a short message submission report to the SMS-IWMSC.

Go to step 7. The SMS-IWMSC sends a short message submission report to the IP-Message-GW. Go to step 8. The IP-Message-GW sends a short message submission report to the IP user equipment. In step 3, the IP-Message-GW does not parse and forward the short message of the IP user, and rejects the message service request of the IP user, and may carry the corresponding authorization failure reason. Do not provide messaging services for them.

The method for obtaining the message service authorization information of the IP user by the IP-Message-GW may be: When an IP user registers, the IP-Message-GW is downloaded from the HLR HSS during the interaction between the IP-Message-GW and the HLR/HSS, or the IP-Message-GW obtains the information stored by the IP-Message-GW. The authorization information is directly configured in the IP-Message-GW.

Method 2: When an IP user sends a message service request to the IP-Message-GW, the IP-Message-GW initiates an authorization process for the IP user message service, and other authorized parties implement the authorization process of the IP user.

The method is basically the same as the process described above with respect to FIG. 8, except that in step 3, the IP-Message-GW sends an authorization request to another authorized party, requesting other authorized parties to check the message service capability of the IP user. The other authorized party judges whether the IP user can use the message service, for example, the IP-Message-GW interacts with the DSMP database of the centralized storage management user data service capability in the network, and the IP-Message-GW provides the IP user identifier to the DSMP, such as the IMSI. Or user identification such as NAI, and further provide service information initiated by the IP user, such as the SMS service. After the DSMP checks the message service capability of the IP user, the information of the authorization success or the authorization failure is returned to the IP-Message-GW, IP- When the message-GW determines that the authorization result returned by the DSMP is the authorization success, the process proceeds to step 4, and continues the subsequent steps. When determining that the authorization result returned by the DSMP is an authorization failure, the IP-Message-GW rejects the message service request of the IP user. Therefore, the IP service is not provided for the IP user.

In this method, during the interaction between the IP-Message-GW and the DSMP, the IP-Message-GW may not provide the service information initiated by the IP user to the DSMP, and the DSMP may according to the address information of the IP-Message-GW that initiates the authorization request. It is determined that the IP user wants to use the message service. The DSMP can also determine that the IP user wants to use other data services according to different service gateway addresses, so that the DSMP can perform different mobile data service authorization for various mobile data service capabilities of the IP user. .

When an IP user establishes a secure connection with the IP-Message-GW based on the IMS network architecture, and the IP user registers with the IP-Message-GW based on the IMS registration procedure, the IP service message authorization process may be performed by the IP-Message-GW. Initiation, the process is similar to steps 3 to 7 shown in Figure 8, and can also be initiated by the S-CSCF. The process of authorizing the message service to the IP user by the S-CSCF is as shown in FIG.

In Figure 9, in step 1, the IP user equipment registers with the S-CSCF according to the IMS registration procedure. in.

Go to step 2, the IP user sends a short message to the S-CSCF based on the SIP MESSAGE mode. In step 3, after receiving the short message sent by the SIP MESSAGE, the S-CSCF obtains the IP user message service authorization information, and determines whether the IP user can use the service. If the S-CSCF determines that the IP user supports the message type service, the authorization succeeds. At the time, the S-CSCF forwards the message to the IP-Message-GW according to the filter information.

Go to step 5. The IP-Message-GW returns a SIP 202 receive message to the S-CSCF, indicating that the message has been received.

Go to step 6. The S-CSCF forwards the SIP 202 to the IP user equipment to receive the message.

In step 7, the IP-Message-GW parses the short message, and forwards the parsed short message to the SMS-IWMSC using standard MAP signaling. The address information of the SM-SC can be parsed from the R-U I part of the MESSAGE or the message body part of the short message.

Go to step 8. The SMS-IWMSC forwards the short message to the SM-SC.

Go to step 9. The SM-SC sends a short message submission report to the SMS-IWMSC.

Go to step 10. The SMS-IWMSC sends a short message submission report to the IP-Message-GW. Go to step 11. IP-Message-GW uses SIP MESSAGE to send a short message submission report to the S-CSCF.

Go to step 12. The S-CSCF uses SIP MESSAGE to send a short message to the IP user equipment to submit a report.

Go to step 13. The IP user equipment uses the 200 ok message to respond to the received short message to submit the report.

To step 14, the 200 ok response message is forwarded to the IP-Message-GW via the S-CSCF. In step 3, if the S-CSCF determines that the IP service user's message service authorization fails, the S-CSCF does not forward the short message to the IP-Message-GW, and does not provide the message service to the IP user.

The method for obtaining the IP user message service authorization information by the S-CSCF may be: the IP user message service authorization information downloaded by the S-CSCF from the HLR/HSS during the registration of the IP user and the interaction with the HLR/HSS.

Similarly, in step 3 of FIG. 9 above, the S-CSCF can also authorize the IP user's service capability by interacting with other user information databases such as DSMP, that is, the S-CSCF will grant The right request is sent to the DSMP, and the DSMP authorizes the IP user's message service according to the stored IP user message service authorization information and authorization request, and returns the authorization success or failure information to the S-CSCF, and the S-CSCF receives the authorization. When successful information, go to step 4 and continue with the next steps. When receiving the information of the authorization failure, the S-CSCF does not forward the short message to the IP-Message-GW, and does not provide the message service to the IP user. The S-CSCF can provide an IP user identifier to the DSMP, such as an IMSI. The S-CSCF can further provide the DSMP with service information initiated by the IP user, such as an SMS service, to request the DSMP to sign the IP user and the operator. Authorization information is checked.

While the invention has been described by the embodiments of the invention, it will be understood that
