technical field

The invention relates to a method, a system device and a short message service center for realizing short messages.

Background of the invention

At present, the call forwarding function is generally provided for voice calls on fixed phones and mobile phones, but not 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 sends 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. Like this, if the user does not turn on the machine within the validity period of the short message retention, the short message of the user will be lost because it is not received in time.

The existing short message system generally does not support the user to set the forwarding of the short message, and cannot meet the user's requirement of transferring the call and the short message to another number at the same time.

Modes of Carrying Out the Invention

An embodiment of the present invention provides a system for realizing short message forwarding, as shown in FIG. 1 . In order to realize short message forwarding, the system mainly transforms the existing short message service center (SMSC, Short Message Service Center), and adds a short message forwarding service component (SMFS, Short Message Forward Service) to realize short message forwarding. Forwarding logic. The implementation process is: provide all downlink short messages (MT, Mobile Terminated SMS) to the SMSC to which the recipient belongs, and judge whether the recipient has opened the short message forwarding service by the SMSC. The SMFS sends a request to inquire about the forwarding destination number, and then sends the short message to the forwarding destination number according to the query result, or processes the short message according to the prior art if the user does not set the forwarding destination number. As a main logical processing unit of the system, SMFS can be implemented as a part of SMSC, or exist as an independent component.

Regarding other components in Figure 1, the business operation support system (BOSS, Business Operation Support System) and the wireless intelligent network (WIN, Wireless Intelligent Network) are respectively connected to the mobile data service platform (MDSP, Mobile Data Service Platform), and the mobile data service platform Connected to the short message service center and the short message forwarding service part, the short message service gateway (SMS GW, Short Message Service Gateway) and the short message Internet gateway (I/O GW, Short Message Input/Output Gateway) are respectively connected to the short message B. In a nutshell, their functions are as follows: the business operation support system mainly completes the management and billing functions of postpaid users; the wireless intelligent network mainly completes the management and billing functions of prepaid users; the mobile data service platform, as the data service A unified service management point, assisting WIN/BOSS to complete the billing and management functions of data services; the short message service gateway is mainly used as an access device for service providers (SP, Service Provider) to access the short message system, and centrally access the short message system. Message-related SP; short message Internet gateway, mainly used as an access device for the interconnection between other network SMSCs (including international SMSCs) and local network SMSCs, and an interconnection access node in the IP bearer mode. In addition, the interface between SMFS and MDSP is mainly used when accepting business. When accepting business, BOSS notifies MDSP, and MDSP notifies SMFS. The business acceptance will be described later.

As for the "local network SMSC", "other network SMSC" and "international SMSC" mentioned above, it refers to a commercial distinction, that is, to distinguish SMSC for different operators. To put it simply, if a network belongs to someone, it is called this network, and other networks can be called other networks relative to this network. It is easy to understand that an international SMSC is a non-domestic SMSC. For example, compared to a Chinese SMSC, a Japanese SMSC is an international SMSC. In this document, international SMSC is also a kind of other network SMSC. It should be further explained that in the following, if an SMSC is referred to as an SMSC of the local network, other SMSCs belonging to the same network as the SMSC are also called SMSCs of the local network, and users belonging to the network to which the SMSC of the local network belongs are users of the local network, and other The user is a user of another network. Other "this network..." and "other network..." appearing hereinafter can be similarly understood.

The system and method for implementing short message forwarding according to the embodiment of the present invention will be described in detail below through an actual scene. FIG. 2 shows a signaling flow of an embodiment of short message forwarding using the method of the present invention. This signaling process can be realized by the system in FIG. 1 . Assume that mobile users (MS, Mobile Station) A, B and C all belong to the SMSC shown in Figure 2, and this SMSC is called the SMSC of the home network. For example, a typical scenario is: A sends a short message to B, and B subscribes to the short message forwarding service and sets the forwarding destination number as C. Combined with this scenario, the description of the signaling process in Figure 2 is as follows:

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

b. SMSC authenticates users A and B. If the authentication fails, the sending fails, and MO_RSP is returned to user A to generate MO bills and end the process;

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

d. MDSP returns the billing result. If the billing fails, the sending fails, and MO_RSP is returned to user A to generate MO bills and end the process;

e. If the billing is successful, return MO_RSP to user A;

f. SMSC generates MO bill;

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

h. If user B subscribes to the short message forwarding service, the SMSC sends a request to SMFS to ask whether user B has set the forwarding destination number;

i. SMFS queries the database and returns the query result; if the query result is that user B has not set the forwarding target user at present, that is, the forwarding destination number corresponding to user B is set to be empty, then SMSC processes it according to the normal short message process;

j. If the result of the query is that user B sets the forwarding destination number C of the short message, the SMSC sends a status report to A, indicating that the short message from A to B is successfully sent;

k. SMSC authenticates user A and user C, if the authentication fails, the sending fails and the process ends;

l. If the authentication is passed, the SMSC submits the forwarded charging request to the MDSP;

m.MDSP returns the accounting result, if the accounting fails, the sending fails and the process ends;

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

o. SMSC checks whether user C has subscribed to the short message forwarding service; if user C has subscribed to the short message forwarding service, then repeat steps h-n;

p. If user C has not subscribed to the short message forwarding service or has not set the forwarding destination number, the SMSC will send a short message to the destination number C;

q. If sending fails, SMSC retry sending according to normal MT short message retry mechanism;

r. If the sending is successful, user C returns the result to SMSC, and SMSC generates MT bill.

Through the process shown in Fig. 2, therefore, for the sake of simplification, only the signaling related to realizing short message forwarding is shown, and some processes known in the prior art and the relevant components involved in them are omitted, as in the step In p, before sending the short message to the destination number C, the SMSC obtains the address of the Visited Mobile Services Switching Center (VMSC, Visited Mobile Services Switching Center) of the user C from the home location register (HLR, Home Location Register) of the user C. .

For the short message sent by the SP to the user, and the situation of forwarding the short message to the SP application, the processing method and flow are the same as the above-mentioned typical flow, except that the number of the SP is usually a special number, such as: 07551860 and so on.

According to the above typical process, forwarding can be performed multiple times, then A->B->C->D->A, A->B->C->D->B, A- >B->A and other infinite loop situations. In view of this, the present invention provides a method for detecting an infinite loop. If the SMSC to which the recipient belongs and other SMSCs belonging to the same network as the SMSC are called the SMSC of the local network, the forwarding destination numbers of the sender and the recipient of the short message may both belong to the SMSC of the local network, or one of them may belong to the SMSC of the local network. Or both belong to other network SMSC. The actual scene of the above short message forwarding process belongs to the former.

Depending on whether the forwarding destination number of the receiving party belongs to the SMSC of the local network or the SMSC of another network, the detection method of the infinite loop is different.

For the situation that the forwarding destination number of the receiving party belongs to the SMSC of the local network, the infinite loop can be avoided by checking when the user sets the forwarding destination number. Generally speaking, for the network to which the SMSC of this network belongs, the relevant data of other network users are unknown. Therefore, the setting process described in detail below is for the number belonging to the SMSC of the home network. That is, 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 that needs to be operated on does not belong to the SMSC of this network, you can directly set the forwarding destination number to be set as the forwarding destination number of the current number. End setup.

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

Put the current number of the forwarding number to be set and the forwarding destination number to be set in a list, and check whether the same number exists in the list: if it exists, it means that there is an infinite loop, and give up the forwarding destination to be set The number is set as the forwarding destination number of the current number, and the setting is completed; if it does not exist, perform the following operations.

For the forwarding destination number to be set (belonging to this network SMSC), check whether it is set with a forwarding destination number, if not, set it as the forwarding destination number of the current number, and end the setting; otherwise, set the forwarding destination number The number is added to the list, and the following operations are performed for the latest number added to the list.

For the latest number added to the list, check whether there is the same number in the list. If it exists, it means that there is an infinite loop. Give up setting the forwarding destination number to be set as the forwarding destination number of the current number, and end the setting; if does not exist, check whether it is set with a forwarding destination number, and

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

(ii) If there is, add its forwarding destination number to the list.

In the case of (ii), repeat the above operations for the numbers newly added to the list until the setting is completed.

As far as "end setting", there are two possibilities: 1. Check that the same number exists in the list, give up setting the forwarding destination number to be set as the forwarding destination number of the current number, and end the setting; 2. Check To a number without a forwarding destination number set, set the forwarding destination number to be set as the forwarding destination number of the current number, and end the setting.

For the situation that the forwarding destination number of the receiving party belongs to another network SMSC (that is, the other network user), since the relevant data of the other network user may not be known, it can only be simply considered that the other network user has not set the forwarding destination number, Send the short message directly to the other network users. By the way, if the other network also supports the short message forwarding service, the SMSC of the other network can perform similar processing on the received short message. In this case, it is not possible to check whether the setting will cause an infinite loop when the user sets the forwarding destination number, and the infinite loop can only be avoided by checking during the sending of the short message. The specific inspection method is: for all short messages forwarded to outside the network, store the sender, receiver and content of the short message in a list in the memory, and the retention time can be set, for example, 30 minutes. In this way, when a short message sent by an SMSC of another network is sent to the SMSC of this network, when the SMSC of this network detects that the short message needs to be forwarded to the outside of the network, it will search in the list mentioned above to check whether there is a short message in the list. If there is a short message with the same sender, receiver and content as the sender, receiver and content of the short message to be forwarded, it is considered that the short message is a repeated short message and is directly discarded. This method for checking the infinite loop can also be used in the situation where the forwarding destination number of the receiving party belongs to the SMSC of this network, that is to say, when the forwarding destination number of the receiving party belongs to the SMSC of this network, the present invention can pass the above-mentioned setting process To avoid the dead loop phenomenon of forwarding, it is also possible to avoid the dead loop phenomenon of forwarding by saving the short message sender, receiver, and content of the short message.

Now explain the situation that the sender of the short message belongs to the SMSC of another network. It is necessary to explain the interconnection mode between the SMSC of this network and the SMSC of other networks, which will be realized later. The SMSC of this network and the SMSC of other networks can be interconnected through I/O GW, and can also be interconnected through signaling.

Fig. 3 shows the situation that the SMSC of the local network and the SMSC of other networks are interconnected through the I/O GW, and the short message point-to-point protocol (SMPP, Short Message Peer to Peer Protocol) can be used as the interface protocol. The SMPP protocol can also be used between the SMS GW and the SMSC, and the internal protocol can be used for the interface between other components. According to the prior art, in this case, all short messages sent to the users of this network from outside the network will be sent to the SMSC of this network, and then sent to the receiving users by the SMSC of this network. Therefore, forwarding can be implemented in a process similar to the above typical process. By the way, when an in-network user sends a short message to an off-network user, the SMSC performs authentication to generate a bill to the BOSS to deduct the fee, and then the short message is sent to the I/O GW, and the I/O GW determines which target it is sent to operator, and then sent to the corresponding operator.

Fig. 4 shows the situation that the SMSC of this network and the SMSC of another network are interconnected through SS7 (SS7, Signaling System 7). The network structure of the other network may be the same as or similar to this network. The network structure of the other network depends on the equipment supplier of the other network. In addition, if the other network does not support the short message forwarding service, the signaling processing system (SPS, Signaling Process System) is optional. The mobile service switching center (MSC, Mobile Switching Center) and the user's home location register (HLR) are the core network (CN, Core Network) components of the mobile network. The HLR saves the user's service activation status, current location, whether the mobile phone memory is full, etc. Information Related to Users. SPS is functionally similar to a router in an IP network. For signaling without specific logic, it is directly transparently transmitted and transparent to other components. The command is sent to, for example, the B component. The SMPP protocol can be used between SMS GW and SMSC, and the internal protocol can be used for the interface between SMSC, SMFS, MDSP, WIN, BOSS and other components.

According to the prior art, when the SMSC of this network and the SMSC of other networks are interconnected by No. 7 signaling, for the short message sent to the user of this network by other network users, the sending process is as follows: the sender submits the short message (SM, Short Message) to its belonging SMSC (other network SMSC), the other network SMSC sends SRL_for_SM to the Gateway Mobile Service Switching Center (GMSC, Gateway Mobile Switching Center) according to the called number, and the GMSC forwards the signaling to the corresponding callee number HLR (local network HLR), the HLR returns the current VMSC address of the called party, and forwards it to the other network SMSC through the GMSC, and the other network SMSC sends the MT_FSM signaling according to the VMSC address, and sends the SM to the corresponding VMSC, and the VMSC sends the short message to the receiver. According to the sending process of the above-mentioned prior art, it can be known that the SM will not pass through the SMSC (the SMSC of the home network) to which the called number belongs.

Therefore, in the situation of FIG. 4, for the short message sent from the user of other network to the user of this network, if the short message is to be forwarded, the short message needs to be intercepted to the SMSC of this network to complete the processing of the forwarding logic. In Figure 4, the SPS is set up to achieve this interception.

Fig. 5 shows the signaling process for intercepting the short message sent by the other network user to the local network user to the local network short message service center for the situation shown in Fig. 4 . The details are as follows. The following local network is relative to the receiving party, and other networks are other networks.

a. Other network SMSC sends SRI_for_SM signaling to get the routing information of the called user to the HLR of this network, the signaling is routed to the GMSC of this network, and the GMSC forwards this signaling to the HLR;

b. SRI_for_SM signaling passes through SPS;

c. SPS checks whether the sending SMSC is the SMSC of the local network. If it is the SMSC of the local network, it will directly send the signaling to the HLR of the local network without processing; if the sending SMSC is an SMSC of another network, check whether the receiving user is The short message forwarding service has been activated. If not, the signaling will be directly sent to the HLR of the local network without processing. It should be noted that when the BOSS accepts the service, it will check whether the user has activated the short message forwarding service. Business information is synchronized to SPS;

d. If the SPS finds that the sending SMSC is an SMSC of another network, and the receiving user has also opened the short message forwarding service, the SPS obtains the routing number "RN" based on this, and changes the SCCP CdPA (the number information to be queried) to It is "RN+MSISDN". What needs to be explained is: "RN" is a special character string corresponding to the GT address of the SMSC in this 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 SCCP CdPA, and then sends the signaling to the GT address;

f. The SMSC of this network 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 VMSC GT address can be found. According to this special VMSC number, SPS sends all the signaling targeted at this address to the SMSC of this network;

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

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

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

j. The SMSC of this network obtains the receiver's forwarding destination number from the SMFS;

k. The SMSC of this network prepares to issue MT signaling to the forwarding destination number;

l. The SMSC of this network sends SRI_for_SM to the HLR to which the forwarding destination number belongs to obtain routing information;

m. When the SRI_for_SM signaling passes through the SPS, the SPS finds that it is a signaling issued by the SMSC of the local network, and directly issues it to the HLR to which the forwarding destination number belongs without processing;

n. Finish sending the short message at last.

Through the process shown in Figure 5, it is intended to illustrate the process of intercepting short messages to the SMSC of this network. Therefore, for the sake of simplicity, some processes after intercepting short messages to SMSC of this network are only briefly described. These processes It is well known in the prior art or reference can be made to the foregoing description.

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

1. According to the target number B, the other network SMSC sends SRI_for_SM to the HLR that user B belongs to, so as to obtain 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 routing of the SRI_for_SM signaling to the SMSC to which user B belongs under the condition that user B has subscribed to the forwarding service;

3. The SMSC returns its own special VMSC address. What needs to be explained is: through a configuration on the SPS, when the SPS finds that the VMSC address is this special address, it will send the relevant signaling to the SMSC of the network;

4. According to the special VMSC address, the other network SMSC sends the MT_FSM signaling to send the short message to the local network SMSC;

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

6. The SMSC of this network sends the SRI_for_SM signaling to the HLR to which C belongs to obtain the routing address of the number C, that is, the VMSC address;

7. SPS finds that it is a signaling issued by the SMSC of this network, and does not intercept it, and the signaling is processed according to the normal process;

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

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

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

Regarding the acceptance of the SMS forwarding service, the SMS forwarding service includes ordering/cancelling the SMS forwarding service, querying the status of the SMS forwarding service, and querying/setting the destination number of the forwarding Forwarding) etc., the short message forwarding service can be realized through the WSI (Web Services Interface, Web Service Interface) provided by BOSS. Other systems can complete business ordering, cancellation and query by calling this interface. The interface can pass Short Message Service (SMS, Short Message Service), Unstructured Supplementary Service Data (USSD, Unstructured Supplementary Services Data), Interactive Voice Response (IVR, Interactive Voice Response), User Portal (End-User Portal) ) and other calls to complete the short message forwarding service acceptance. For example, calling via SMS means that the user can use the mobile phone to send a short message with specified content to a specified number (SP number). After the SMSC transfers the relevant short message to the corresponding application program, the service can be completed by calling the interface provided by BOSS. accepted. IVR is usually an automatic voice service desk system, such as: 1860, 13800138000 and other voice interaction systems.

With regard to billing, the system shown in FIG. 1 can support free, monthly billing, item billing, and combined billing. The application scenarios are suggested as follows: a) charge users for the basic monthly fee for using this service; b) when forwarding short messages, if they are forwarded to users within the network, no charging is required; if they are forwarded to users on other networks, A certain fee will be charged according to the article.

Monthly billing: For prepaid users, in each billing period (the billing period refers to the cycle of a user bill settlement, such as a user's bill settlement cycle from the 5th of each month to the 5th of the next month, and provide the user bill Billing to the user) At the beginning, the MDSP initiates a request to the WIN system to deduct the monthly fee for the monthly subscription, and outputs the bill for reconciliation; for post-paid users, at the end of each billing period, the bill is generated by the MDSP, BOSS obtains bills from MDSP and charges corresponding fees for postpaid users.

Billing by item: For prepaid users, SMSC initiates a billing request to MDSP, and MDSP judges whether charging is required according to the forwarding destination number, and if billing is required, calculates the amount to be charged, and MDSP initiates a request to the WIN system to deduct the corresponding amount charge, and output the bill for reconciliation; for postpaid users, the SMSC initiates a billing request to the MDSP, and the MDSP judges whether it needs to be charged and calculates the amount of the fee according to the forwarding destination number, and the MDSP generates the bill, and the BOSS The MDSP obtains the bill and charges the corresponding fee for the postpaid user.

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

Utilizing the present invention, the user can set the user's short message forwarding service related information in various ways such as short message, voice, USSD, Portal, etc., and forward the short message to other numbers or SP applications. When a user uses multiple numbers, he can only use one of the numbers to receive calls and short messages, or submit short messages to a third party for processing. Can receive and process short messages in time.

The interception device provided by the invention includes a judgment module and an interception module. The judging module and the intercepting module can intercept the short message sent by the other network user to the local network user to the short message service center to which the local network user belongs.

When the judging module determines that the SMSC of the receiver of the short message is an SMSC of another network, and the user of the receiving party has opened the service of forwarding the short message, it notifies the intercepting module. After receiving the notification from the judging module, the interception module obtains the routing number "RN", and changes the SCCP CdPA (the number information of the route to be queried) to "RN+MSISDN", the interception module performs SCCP GT translation according to the SCCP CdPA, and converts the message After receiving the special VMSC address returned by the SMSC of the local network, the interception module sends all the signaling targeted at this address to the SMSC of the local network. The specific implementation process is as described for the SPS in the foregoing implementation manner.

The short message forwarding service device provided by the present invention includes a query module, which stores the forwarding destination number of the user. After receiving the information that the short message service center inquires whether the current recipient is provided with a forwarding number, the query module according to The stored information inquires whether the current receiver it receives has set the forwarding destination number, and notifies the short message service center of the search result. 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 invention includes a query interface module and a sending module. The query interface module inquires whether the current recipient of the short message is provided with a forwarding destination number to the short message forwarding service device, and the query interface module will inquire when receiving the search result information that the current recipient is provided with a forwarding destination number. Notify the sending module of the forwarding destination number. The sending module regards the forwarding destination number notified by the query interface module as the current receiver, and judges whether the current receiver belongs to the network to which the short message service center belongs. If it is determined that the current receiver 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 recipient is provided with a forwarding destination number, and after the query interface module receives the search result information that the current recipient is provided with a forwarding destination number again, Notify the sending module of the forwarding destination number found again. The sending module continues to take the forwarding destination number of the query notification as the current receiver, and continues to judge 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 has not set the forwarding destination number. When the sending module receives the information transmitted by the query interface module that the current recipient has not set the forwarding destination number, it determines the current recipient as the final recipient, and sends a short message according to the final recipient. When the sending module determines that the current receiver does not belong to the network to which the short message service center belongs, it determines the current receiver as the final receiver, and sends the short message according to the final receiver. The specific implementation process is as described in the foregoing embodiments.

While a preferred embodiment of this invention has been described, those skilled in the art will be able to make various modifications to the embodiment disclosed herein upon reading and grasping the principles and teachings of this invention.
