 Currently, call forwarding is generally provided for voice calls between landline and mobile phones, and this feature is not provided for short messages.

 The short message service is based on the store-and-forward mode, that is, the short message service center saves the short message, and then delivers the stored short message to the user's terminal when the user can receive it. If the user has not received the short message within the set maximum message retention period, the short message service center will discard the short message. In this way, if the user does not boot during the short message retention period, the user's short message will be lost because it is not received in time.

 The existing short message system generally does not support the user to set forward the short message, and cannot meet the requirement that the user wants to transfer the call and the short message to another number at the same time. Summary of the invention

One embodiment of the present invention provides a system for implementing short message forwarding, as shown in FIG. In order to implement the short message forwarding, the system mainly transforms the short message service center (SMSC) of the prior art, and adds a Short Message Forward Service (SMFS) to achieve short The logic of message forwarding. The implementation process is: Put all the downlink short messages (MT, Mobile Terminated SMS) is provided to the SMSC of the receiver, and the SMSC determines whether the receiver has opened the short message forwarding service. If the receiver user activates the service, it sends a request to the SMFS to request the forwarding destination number, and then According to the result of the query, the short message is sent to the forward destination number, or the short message is processed according to the prior art if the user does not set the forward destination number. As a main logical processing unit of the system, SMFS can be implemented as part of the SMSC or as a separate component.

 For the other components of Figure 1, the Business Operation Support System (BOSS) and the Wireless Intelligent Network (WIN, Wireless Intelligent Network) are respectively connected to the Mobile Data Service Platform (MDSP), the mobile data service platform. Connect to the short message service center and the short message forwarding service component, Short Message Service Gateway (SMS GW) and Short Message Input/Output Gateway (I/O GW, respectively) are connected to the short message B. In summary, their functions are as follows: the business operation support system mainly completes the management and billing functions of post-paid users; the wireless intelligent network mainly completes the management and billing functions of prepaid users; and the mobile data service platform as a data service Uniform service management point, assisting WIN/BOSS to complete the billing and management functions of the data service; Short message service gateway, mainly as the service provider (SP, Service Provider) accessing the short message system access device, centralized access Short message related SP; Short message Internet gateway, mainly as an access device interconnected by the SMS network (including the international SMSC) and the local network SMSC, is an interconnection access node of the IP bearer mode. In addition, the interface between the SMFS and the MDSP is mainly used during business reception. When the service is accepted, the BOSS notifies the MDSP, and the MDSP notifies the SMFS. The business acceptance will be described later.

 Regarding the above-mentioned "this network SMSC", "other network SMSC" and "international SMSC", here refers to a commercial distinction, that is, to distinguish SMSC for different operators. Simply put, if a network belongs to whom the network is called the network, other networks can be called other networks. It is easy to understand that the international SMSC is not a domestic SMSC, such as: Compared to China's SMSC, Japan's SMSC is an international SMSC. In this document, the International SMSC is also a kind of SMSC. It should be further noted that, in the following, if one SMSC is referred to as the SMSC of the network, the other SMSCs belonging to the same network as the SMSC are also referred to as the local network SMSC, and the users belonging to the network to which the SMSC belongs to the local network are the users of the network, and others The user is a user of the network. Other "this net..." and "he net..." which appear below are similarly understood.

The system and method for implementing short message forwarding in accordance with an embodiment of the present invention are described in detail below through an actual scenario. Figure 2 illustrates an embodiment signaling flow for short message forwarding using the method of the present invention. This signaling flow can be implemented by the system of Figure 1. It is assumed that the mobile users (MS, Mobile Station) A, B, and C all belong to the SMSC shown in FIG. 2, and the SMSC is referred to as the SMSC of the network. For example, a typical scenario is: A sends a short message to B, B ordered the short message forwarding service and set the forwarding destination number to C. Combined with this scenario, the description of the signaling flow in Figure 2 is as follows:

 a. The user of the network A sends a short message to the user of the network B, A's MO request is submitted to the SMSC;

 b. The SMSC authenticates the users A and B. If the authentication fails, the sending fails, and the MO-RSP is returned to the user A to generate the MO bill, and the process ends.

 c If the authentication is passed, the SMSC submits the charging request to the MDSP;

 d. The MDSP returns the charging result. If the accounting fails, the sending fails. The MO_RSP is returned to the user A to generate the MO bill, and the process ends.

 e. If the billing is successful, return MO-RSP to user A;

 f. SMSC generates MO bills;

 g. SMSC checks whether user B has subscribed to the short message forwarding service; if B does not subscribe to the short message forwarding service, it is processed according to the normal short message process;

 h. If user B subscribes to the short message forwarding service, the shell lj SMSC sends a request to the SMFS, asking if the user B is set to set the forward destination number;

 i. SMFS queries the database, returns the query result; If the query result is that user B does not currently set the forward target user, that is, the forwarding destination number corresponding to user B is set to null, and the SMS1 is processed according to the normal short message flow; If the result of the query is that the user B sets the forward destination number C of the short message, the SMSC sends a status report to A, indicating that the short message of A to B is successfully sent;

 k. SMSC authenticates user A and user C. If the authentication fails, the transmission fails, and the process ends. 1. If the authentication is passed, the forwarded charging request is submitted by the SMSC to the MDSP;

 m. The MDSP returns the charging result. If the accounting fails, the sending fails, and the process ends.

 n. If the billing is successful, Bjj SMSC generates a forwarded bill;

 0. The SMSC checks whether the user C subscribes to the short message forwarding service; if the user C subscribes to the short message forwarding service, the step h-n is repeated;

 p. If user C does not subscribe to the short message forwarding service or does not set the forwarding destination number, the SMSC sends a short message to the destination number C;

 q. If the transmission fails, the SMSC retryes the delivery according to the normal MT short message retry mechanism;

 r. If the transmission is successful, User C returns the result to SMSC, and SMSC generates the MT ticket.

Through the flow shown in FIG. 2, for the sake of simplicity, only the signaling related to the implementation of the short message forwarding is shown, and some processes known in the prior art and related components involved in them are omitted, such as in the steps. In p, in the issuance Before the short message arrives at the destination number C, the SMSC obtains the address of the Visited Mobile Services Switching Centre (VMSC) of the user C from the home location register (HLR, Home Location Register) to which the user C belongs.

 For the short message sent by the SP to the user, and the case where the short message is forwarded to the SP application, the processing and process are the same as the above typical process, except that the SP number is usually a special number, such as: 07551860.

 According to the above typical process, multiple forwards can be performed, then A->B->C->D->A, A->B->C->D->B, A- may appear during the forward process. >B->A and other dead loops. In view of this, the present invention provides a method of detecting an infinite loop. If the SMSC to which the receiver belongs and the other SMSCs that belong to the same network as the SMSC are referred to as the local network SMSC, the forward destination number of the sender of the short message and its receiver may belong to the local network SMSC, or one of them. Or both belong to the other network SMSC. The actual scenario of the above short message forwarding process belongs to the former.

 According to the forward destination number of the receiver, it belongs to the SMSC of the network or the SMSC of the other network. The detection method of the infinite loop is different. -

 For the case where the forward destination number of the receiver belongs to the SMSC of the local network, the infinite loop can be avoided by checking when the destination number is changed before the user sets. Generally speaking, for the network to which the SMSC of this network belongs, the related data of the other network users is unknown. Therefore, the setting procedure to be described in detail below is for the number of the home network SMSC. SP, in the following setting process, when performing related operations on a certain number, it implicitly indicates that the number belongs to the SMSC of the local network. It is easy to understand that, in the following setting process, once it is found that the number for which the related operation needs to be performed is not attributed to the local network SMSC, the forwarding destination number to be set can be directly set as the forwarding destination number of the current number. End the settings.

 Under the above premise, the setting process can be performed as follows.

 Put the current number of the forwarding number to be set and the forwarding destination number to be set in a list, check whether the same number exists in the list: If it exists, it indicates that there is an infinite loop, and the forwarding is set to be abandoned. The destination number is set to the forward destination number of the current number, and the setting is ended. If it does not exist, perform the following operations.

 For the forwarding destination number to be set (the home network SMSC), check whether it has a forwarding destination number. If not, set it to the current destination forwarding destination number and end the setting; otherwise, forward it. The destination number is added to the list, and the following operations are performed for the latest number added to the list.

For the number added to the list, check whether the same number exists in the list. If it exists, it indicates that there is an infinite loop, and the previous destination number to be set is set to the forward destination number of the current number, and the setting is ended. If it does not exist, check if it has a forwarding destination number, and

 (i) If not, set the forward destination number to be set to the forward destination number of the current number, end the setting, or

 (ii) If yes, add its forward destination number to the list.

 In the case of (ii), the above operation for the latest number added to the list is repeated until the setting is ended. As far as "end setting" is concerned, there are two possibilities: 1. Check that the same number exists in the list, and give up the forward destination number to be set as the forward destination number of the current number, and end the setting; Check the number of the destination number that has not been set, set the forward destination number to be set to the forward destination number of the current number, and end the setting.

 For the case where the forward forwarding destination number of the receiver belongs to the other network SMSC (that is, the other network user), since the related data of the other network user may not be known, the user of the other network may simply be considered that the destination user number is not set. Send the short message directly to the other network user. By the way, if he also supports short message forwarding business, then he

The SMSC can perform similar processing on the received short message. In this case, it is not possible to check if the setting causes an infinite loop when the user sets the forward destination number, and can only avoid the dead loop by checking during the short message transmission. The specific check method is: For all short messages that are forwarded to the network, the sender, receiver, and short message contents are stored in a list in the memory, and the retention time can be set, for example, for 30 minutes. In this way, when a short message sent by the SMSC of another network is sent to the SMSC of the local network, when the SMSC of the network detects that the short message needs to be forwarded to the network, it searches in the list mentioned above to check whether it is There are senders, receivers, and content. The short message is the same as the sender, receiver, and content of the forward-to-forward short message. If it exists, the short message is considered as a duplicate short message and is directly discarded. The method for checking the infinite loop can also be used when the forward forwarding destination number of the receiver belongs to the SMSC of the local network, that is, when the forward forwarding destination number of the receiver belongs to the SMSC of the local network, the present invention can pass the above setting process. To avoid the phenomenon of forward loop, you can also avoid the phenomenon of forward loop by saving the short message sender, receiver, and short message content.

 Now that the sender of the short message belongs to the SMSC of the other network, it is necessary to explain the interconnection between the SMSC of the network and the SMSC of the other network, which will be realized later. The SMSC of this network and the SMSC of other networks can be interconnected by I/O GW or by signaling.

Figure 3 shows the situation in which the SMSC of the local network and the SMSC of the other network are interconnected by the I/O GW. The Short Message Peer to Peer Protocol (SMPP) can be used as the interface protocol. The SMPP protocol can also be used between the SMS GW and the SMSC, and the interfaces between other components can use internal protocols. According to the prior art, in this case, all short messages sent from the network to the users of the network will be sent to the SMSC of the network, and the SMSC of the network Issued to the receiving user. Therefore, the process can be forwarded similarly to the typical process described above. Incidentally, when the user in the network sends a short message to the user outside the network, the SMSC performs authentication to generate a bill to the BOSS deduction, and then the short message is sent to the I/O GW, which is determined by the I/O GW. The operator's, and then sent to the corresponding operator.

 Figure 4 shows the situation where the SMSC of the local network and the SMSC of the other network are interconnected by SS7 (Signing System 7). The network structure of the other network may be the same or similar to the network. The network structure of the other network depends on the equipment supplier of the other network. In addition, if the network does not support the short message forwarding service, the signaling processing system (SPS, Signaling Process) System) is optional. The Mobile Switching Centre (MSC) and the User Home Location Register (HLR) are the core network (CN, Core Network) components of the mobile network. The HLR stores the user service opening status, the current location, and whether the mobile phone memory is full. Information related to the user. The SPS is similar in function to the router in the IP network. For signaling without specific logic, it is directly transparently transmitted and transparent to other components. If signaling interception is required, it should be sent to, for example, the A component according to the configuration conditions. Signaling is sent to, for example, the B component. The SMPP protocol can be used between SMS GW and SMSC. The interface between components such as SMSC, SMFS, MDSP, WIN, BOSS can use internal protocols.

 According to the prior art, when the SMSC of the local network and the SMSC of the other network are interconnected by the SS7 signaling, the short message sent by the user of the other network to the user of the local network is sent as follows: The sender submits the short message (SM, Short) Message to the SMSC (the other network SMSC) to which it belongs, the SMSC sends the SRI_for_SM to the Gateway Mobile Switching Centre (GMSC) according to the called number, and the GMSC transfers the signaling to the called party. The HLR (the local network HLR) corresponding to the number, the HLR returns the current VMSC address of the called party, and transfers it to the other party's SMSC through the GMSC. The other network SMSC sends the MT-FSM signaling according to the VMSC address, and delivers the SM to the corresponding VMSC. The VMSC sends the short message to the receiver. According to the above-described prior art transmission process, it can be seen that SM is an SMSC (Local Network SMSC) that does not pass the called number.

 Therefore, in the case of FIG. 4, for the short message sent by the user of the other network to the user of the network, in order to implement the short message forwarding, the short message needs to be intercepted to the SMSC of the network to complete the processing of the forwarding logic. In Figure 4, SPS is set to implement this interception.

 FIG. 5 shows a signaling flow for intercepting a short message sent by a user of another network to a user of the network to the short message service center of the local network for the scenario shown in FIG. The details are as follows. The following networks are all relative to the receiver, and other networks are other networks.

 a. The SMSC sends the SRI-for-SM signaling to the HLR of the local network to obtain the routing information of the called user, and the signaling is routed to the GMSC of the local network, and the GMSC forwards the signaling to the HLR;

b. SRI-for-SM signaling passes SPS; c. The SPS checks whether the sender SMSC is the SMSC of the network. If the SMSC is the backbone network, the signaling is directly sent to the local network HLR, and no processing is performed; if the sender SMSC is the other network SMSC, the receiver is checked. Whether the user has opened the short message forwarding service. If it is not enabled, the signaling is sent directly to the HLR of the local network. No processing is required. The BOSS needs to open the short message when the service is accepted. The information of the forwarded service is synchronized to the SPS;

 d. If the SPS finds that the sender SMSC is the other network SMSC, and the receiver user also activates the short message forwarding service, the Bayu SPS obtains the routing number "RN" based on this, and sets the SCCP CdPA (number information of the route to be queried) Changed to "RN+MSISDN", it should be noted that: "RN" is a special string that corresponds to the GT address of the SMSC of the local network. This correspondence can be pre-configured;

 e. SPS performs SCCP GT translation according to SCCP CdPA, and routes the signaling to the SMSC of the local network. Specifically, it searches for the GT code according to the RN in the SCCP CdPA, and then sends the signaling to the GT. address;

 f. The local network SMSC returns a special VMSC address in the SRI-for-SM_Ack signaling. It should be noted that: This is also pre-configured. According to the RN in the SCCP CdPA in the SRI_for_SM signaling, a pre-configured one can be found. The VMSC GT address, according to the special VMSC number, the SPS sends the signaling destined for this address to the SMSC of the local network;

 g. Other network SMSC sends MT to the corresponding VMSC;

 h. According to the above special VMSC address, the SPS routes the MT signaling to the SMSC of the local network;

 i. The SMSC of the network receives the MT signaling;

 j. This network SMSC obtains the forward destination number of the receiver from the SMFS;

 k. The SMSC of this network is ready to deliver MT signaling to the forwarding destination number;

 1. The SMSC of the local network sends the SRI-for-SM to the HLR to which the forwarding destination number belongs to obtain the routing information; m. When the SRI_for_SM signaling passes the SPS, the SPS finds the signaling sent by the SMSC of the local network, and directly sends the signaling without the processing. The HLR to which the forwarding destination number belongs;

 n. Finally, the delivery of the short message is completed.

 Through the process shown in FIG. 5, the process of intercepting the short message to the SMSC of the local network is described. Therefore, for the sake of simplicity, some processes after intercepting the short message to the SMSC of the local network are simply described. It is well known in the art or can be referred to the previous description.

 A more specific example is given below. For example, the user A of the network sends a short message to the user B of the network, and the user B sets the short message to the user C. The process is as follows:

1. The other network SMSC sends the SRI for SM to the HLR to which the user B belongs according to the target number B. Take the VMSC address of user B;

 2. When the SRI_for-SM signaling arrives at the SPS of the local network, the SPS modifies the SRIJfor-SM signaling to the SMSC to which the user B belongs if the user B has subscribed to the forwarding service.

 3. The SMSC returns its own special VMSC address. It should be noted that by making a configuration on the SPS, when the SPS finds that the VMSC address is this special address, it sends the relevant signaling to the SMSC of the network;

 4. The SMSC sends the MTJFSM signaling according to the special VMSC address, and sends the short message to the SMSC of the lj network;

 5. The SMSC of the network interacts with the SMFS to obtain the forward destination number C of B;

 6. The SMSC of the local network sends the SRI-for-SM signaling to the HLR to which the C belongs to obtain the routing address of the number C, that is, the VMSC address;

 7. The SPS discovery is the signaling sent by the SMSC of the local network. The interception is not performed, and the signaling is processed according to the normal process;

 8. The HLR to which the user C belongs returns the VMSC address of the user C to the SMSC of the network;

 9. The SMSC of the local network sends the MT_FSM signaling to the corresponding VMSC, and sends the short message to the VMSC where the user C is located.

 10. The VMSC delivers the short message to user C.

 Regarding the acceptance of the short message forwarding service, the short message forwarding service includes ordering/cancelling the short message forwarding service, querying the short message forwarding business status, and querying the user/setting the forward destination number (the setting can be empty, indicating that the current is not present Turn), etc., short message forwarding business can be realized by WSI (Web Services Interface, Web Service Interface) provided by BOSS. Other systems can complete the ordering, cancellation, and query of services by calling this interface. The interface can pass short message service (SMS, Short Message Service Unstructured Supplementary Service Data (USSD), Interactive Voice Response (IVR), User Portal (End-User Portal), etc. Called to complete the short message forwarding business acceptance. For example, through the SMS call, the user can use the mobile phone to send the short message of the specified content to the specified number (SP number), and the SMSC transfers the related short message to the corresponding application. The service can be completed by calling the interface provided by BOSS. The IVR is usually an automatic voice service desk system, such as: 1860, 13800138000, etc.

 Regarding billing, the system shown in Figure 1 can support free, monthly billing, billing by billing, and combined billing. The application scenarios are as follows: a) The basic monthly subscription fee for the user to use the service; b) When the short message forward is forwarded, if the user is forwarded to the network, the user may not be charged, if the user is forwarded to the other network, Then a fee will be charged according to the article.

Monthly billing: For prepaid users, in each account period (account period refers to a period of one user bill settlement, such as a certain Each user is a call billing cycle from 5th to 5th of the month, and provides the user bill to the user. At the beginning, the MDSP initiates a request to the WIN system to deduct the monthly subscription fee, and outputs the bill for the first time. Reconciliation use; For post-paid users, at the end of each account period, the CDR is generated by the MDSP, and the BOSS obtains the CDR from the MDSP and charges the corresponding fee for the post-paid user.

 According to the bar billing: For the prepaid subscriber, the SMSC initiates the charging request to the MDSP, and the MDSP determines whether the charging is required according to the forwarding destination number. If the charging is required to calculate the amount of the fee, the MDSP initiates a request to the WIN system to deduct the corresponding amount. Cost, and output CDRs for reconciliation; For post-paid users, the SMSC initiates a charging request to the MDSP. The MDSP determines whether it needs to charge and calculate the amount of the charge based on the forwarding destination number. The MDSP generates the CDR, BOSS from The MDSP gets the bill and charges the postpaid user accordingly.

 The system and method according to the present invention supports unconditional forwarding of short messages, and the number of forwarding times is not limited, and is applicable to mobile communication networks, fixed communication networks, and PHS (Personal Handphone System) networks.

 With the present invention, the user can set the short message forwarding service related information of the user through various methods such as short message, voice, USSD, and portal, and forward the short message to other numbers or SP applications. When a user uses multiple 'numbers, they can use only one of them to receive calls and short messages, or submit short messages to third parties for processing. You can receive and process short messages in a timely manner.

 - The intercepting device provided by the present invention comprises a judging module and an intercepting module. The judging module and the intercepting module can intercept the short message sent by the user of the other network to the user of the local network to the short message service center to which the user of the network belongs.

 The judging module notifies the intercepting module when it is determined that the short message receiving party's SMSC is the other network SMSC, and the receiving party user also opens the short message forwarding service. After receiving the notification from the judgment module, the interception module obtains the routing number "RN", and changes the SCCP CdPA (number information of the route to be queried) to "RN+MSISDN", and the interception module performs SCCP GT translation according to SCCP CdPA, The signaling is routed to the local network SMSC. After receiving the special VMSC address returned by the local network SMSC, the interception module sends the signaling with the destination address to the local network SMSC. The specific implementation process is as described in the above embodiment of the SPS.

 The short message forwarding service device provided by the present invention comprises a query module, wherein the query module stores the forward destination number of the user, and the query module receives the short message service center to query whether the current receiver has the information of the forwarded number. According to the information stored therein, it is queried whether the current receiving party received by the current receiver is set with a forwarding destination number, and notifies the short message service center of the search result. The content of the specific signaling interaction between the query module of the short message forwarding service device and the short message service center is as described in the above embodiment.

The short message service center provided by the present invention includes a query interface module and a sending module. The query interface module queries the short message forwarding service device to query whether the current recipient of the short message has a forwarding destination number, and the query interface module is connected. When receiving the search result information of the forward destination destination number set by the current collection party, the forwarding destination number of the inquiry is notified to the sending module. The sending module uses the forwarding destination number notified by the interface module as the current receiving party, and determines whether the current receiving party belongs to the network to which the short message service center belongs. If it is determined that the current receiving party belongs to the network to which the short message service center belongs, Then notify the query interface module. The query interface module continues to query the short message forwarding service device according to the notification of the sending module whether the current receiving party has set the forwarding destination number, and the query interface module receives the search result information of the forwarding destination number set by the current receiving party again. The sending destination module will be notified of the forwarding destination number that is queried again. The sending module continues to use the forward destination number of the query notification as the current receiver, and continues to determine whether the current receiver belongs to the network to which the short message service center belongs. The query interface module notifies the sending module when receiving the search result information that the current receiving party does not set the forwarding destination number. When receiving the information that the current receiver does not set the forwarding destination number, the sending module determines the current receiver as the final receiver, and sends a short message according to the final receiver. When the sending module determines that the current recipient does not belong to the network to which the short message service center is located, the sending module determines the current recipient as the final recipient, and sends a short message according to the final recipient. The specific implementation process is as described in the above embodiment.

 While the invention has been described with respect to the preferred embodiments of the embodiments of the invention Therefore, the scope of the invention is defined by the claims appended hereto.
