The existing call forwarding service refers to a mobile communication service that can transfer an incoming call to a user's preset forwarding number (such as a voice mail box, a secretarial desk, a mobile phone, or a fixed telephone, etc.) when the user cannot answer the call. The user preset number can include: fixed or mobile phone number, global channel, Chinese text message station, voice mail number, automatic pager number.

Several common call forwarding modes are:

(1) No answer call: If the user's mobile phone rings without answering (pre-set the answering time, for example, 30 seconds), then all calls to the user's phone are transferred to the user's preset phone number. Depending on the phone model, the ringing time is not exactly the same, usually 30-60 seconds. For example, if the user sets the answering call time of the unanswered forward call to 20 seconds, the user can answer the call normally within 20 seconds after the phone starts to call, and if the call is not answered, the call will be made.

(2) Unreachable forward: If the user cannot make a normal call due to the phone being turned off, not in the valid service area, or the signal is poor, all calls to the user will be transferred to the phone number preset by the user.

(3) Busy forward: If the user is on a call, all calls to the user are transferred to the phone number preset by the user.

(4) Unconditional forward: All calls are forwarded, and all incoming calls to the user's mobile phone are transferred to the number preset by the user.

In order to facilitate the description of the method for implementing call forwarding provided by the embodiment of the present invention, in the following description, the Mobile Switching Center (MSC) to which the called terminal belongs is referred to as the first MSC, and the MSC to which the calling terminal belongs is referred to. It is called the second MSC.

The method for implementing call forwarding provided by the embodiment of the present invention is first described in detail below.

As shown in FIG. 1, the method for implementing call forwarding provided by the embodiment of the present invention includes the following steps:

S101. The first MSC or the personalized call forwarding service platform receives a call setup request of the calling terminal.

5102, the first MSC or the personalized call forwarding service platform returns the indication information of the call forwarding and the call forwarding transfer number set by the called terminal in real time, to the second MSC;

5103. The second MSC connects the call to the called terminal according to the received indication information or connects to the forwarding number specified by the indication information.

In the above steps S102 and S103, the forwarding number of the call forwarding indicates the destination number to which the call is transferred. According to the foregoing steps S101 to S103, it can be seen that the method for implementing call forwarding provided by the embodiment of the present invention can actually have two implementation manners. The network architecture applicable to the first implementation manner is as shown in FIG. 2, and the network architecture and The existing network architecture is the same;

The network architecture diagram used in the second embodiment is shown in FIG. 3. FIG. 3 is a new network entity, that is, a personalized call between the first MSC and the second MSC, based on the existing network architecture. Transfer platform.

The method for implementing call forwarding provided by the embodiment of the present invention is described in detail below for the two different embodiments.

The first embodiment:

In the first embodiment, the step S101, that is, the first MSC receives the call setup request of the calling terminal by using the following process, which specifically includes the following steps:

The second MSC receives a call setup request initiated by the calling terminal under its jurisdiction; the call setup request carries the number of the called terminal that the calling terminal needs to call;

The second MSC queries the mobile station roaming number (MSRN) of the called terminal;

The second MSC determines, according to the MSRN of the called terminal, the first MSC to which the called terminal belongs;

The second MSC connects the call setup request to the determined first MSC, and the call setup request to the first MSC may use existing bearer independent call control BICC signaling or other existing signaling.

In the foregoing step S102, specifically, the first MSC obtains the indication information set by the called terminal by: the first MSC initiates a call to the called terminal when receiving the call setup request initiated by the calling terminal; After the terminal rings, it displays on the called terminal interface whether to request user input for call forwarding and call forwarding. The prompt information of the transferred transfer number, after the user inputs, the called terminal returns to the first MSC;

The first MSC receives the indication information returned by the called terminal.

In the above step S103, there are two cases. If the user needs call forwarding, the second MSC removes the connection with the first MSC and the called terminal, and then calls the MSC corresponding to the transfer number specified by the call indication information, and calls the call. The MSC to which the number belongs connects the call to the mobile terminal corresponding to the transfer number. In another case, the user does not need the call transfer, the call is directly connected to the called terminal. The specific implementation of the two cases belongs to the prior art. The scope is not repeated here.

Preferably, in order to let the user of the calling terminal know which transfer number the call is transferred to, the call terminal may return the notification short message to the calling terminal while the call is connected to the transfer number, and the notification is short. The transfer number is carried in the message. The text message content can be a preset fixed format or can be input by the user in real time.

In order to better describe the specific implementation process of the foregoing first embodiment, a specific signaling interaction process is used.

The signaling flow is shown in Figure 4. In this process, the called terminal selects call forwarding in real time. The MSC Sever A initiates a call setup request to the MSC Sever A to which the MSC Sever A belongs, and the MSC Sever A queries the HLR B for the MSRN number of the called terminal.

Step 7. The MSC Sever A connects the call setup request to the MSC Sever B;

Step 8-11, MSC Sever B calls UE B;

Step 12: UE B starts ringing;

Step 13. The user selects a call transfer on UE B and inputs a transfer number.

Step 14: UE B sends Redirect C signaling to MSC Sever B, indicating that the call is transferred to the C number. Steps 15-27, the calling switch removes the connection with the called B, and initiates a call to the number C.

In the first embodiment, the processing flow of the called terminal side is as shown in FIG. 5. On the called terminal side, the called terminal can select to answer or perform call forwarding according to the user's requirement. When the call forwarding is selected, the user inputs or The call forwarding transfer number is directly selected in the contact list, and then the call of the calling terminal is connected to the transfer number. After the call transfer, the called terminal can also select whether to send the call forwarding prompt message to the calling terminal, and the user selects If yes, the short message of the corresponding content is sent to the calling terminal, and the short message content can be input by the called party in real time, or preset.

In the first embodiment, the existing MSC Server needs to be upgraded so that it can support the various signaling and service processes described above for real-time call forwarding. For the terminal side, software or hardware upgrade is also required. It can support the various signaling and business processes described above for real-time call forwarding.

The second embodiment:

In the second implementation manner, the step S101, that is, the personalized call forwarding service platform receives the call setup request of the calling terminal, specifically includes the following steps:

The second MSC receives a call setup request initiated by the calling terminal under its jurisdiction; The second MSC queries whether the calling terminal subscribes to the personalized call forwarding service; if yes, sends a call setup request carrying the called terminal number to the personalized call forwarding service platform; if not, processes according to the prior art.

In the foregoing step S102, specifically, the personalized call forwarding service platform can obtain the indication information set by the called terminal in the following two manners:

The method, that is, when the call is initiated, the indication information is obtained from the called terminal in real time, and the specific process is as follows: The personalized paging service platform resides in the called terminal number, and sends the unstructured to the first MSC to which the called terminal belongs. An Unstructured Supplementary Service Data (USSD) request; the USSD request carries a prompt message requesting the user to input whether to perform a call transfer and a transfer number of the call transfer;

The first MSC forwards the USSD request to the called terminal;

After receiving the USSD request, the called terminal displays an interface prompting it to input the indication information. After the user inputs, the terminal records the indication information, and the interface of the called terminal is displayed as shown in FIG. 6 . Preferably, the menu can be used to facilitate the user to complete the selection.

The first MSC receives the prompt information of the forwarding number of the call forwarding and the call forwarding returned by the called terminal, and returns the message to the personalized call forwarding service platform through the USSD Continue message.

Another way is to synchronize the terminal to the personalized call forwarding service platform in advance. The specific process is as follows:

The called terminal synchronizes the indication information of the forwarding number that needs to be forwarded by the user and the call forwarding to the personalized call forwarding service platform according to the needs of the user;

The personalized call forwarding service platform stores indication information of each terminal that is synchronized.

The user can select and change the forwarding number of the call forwarding and call forwarding in real time according to the real-time needs of the user, or the current environment. The called terminal can according to the instruction input by the user every time the change is made. Real-time synchronization to the personalized call forwarding service platform, real-time update by the personalized call forwarding service platform.

The personalized call forwarding service platform can locally save the mapping table of calling number/call mode. An example is shown in Table 1:

Table 1

Preferably, the manner in which the called terminal synchronizes the indication information may use a short message method, a Wireless Application Protocol (WAP) mode, a USSD mode, or the like.

Preferably, in order to let the user of the calling terminal know which transfer number the call is transferred to, the call is connected. While continuing to the transfer number, you can also perform the following steps:

The personalized call forwarding service platform sends a USSD PUSH message to the second MSC; the USSD PUSH message carries the forwarding number set by the called terminal;

The second MSC forwards the USSD PUSH message to the calling terminal;

The calling terminal displays the forwarding number to the user according to the USSD PUSH message.

To better describe the specific implementation process of the foregoing second embodiment, a specific signaling interaction process is used.

The signaling process is shown in FIG. 7. In the process, the called terminal selects call forwarding in real time (of course, the call forwarding can be preset and synchronized to the personalized call forwarding service platform, which is only used as a specific example. Before the start of the process, the UE B subscribes to the personalized call forwarding service (the subscription data of the HLR in which the user subscribes to the service). The process is as follows:

Step 1. UE A initiates a call to UE B.

Step 2-3: The MSC SERVER A to the HLR queries the user data, and finds that the UE B subscribes to the personalized call forwarding service; Step 4-5, the MSC SERVER A initiates an initial detection point (Initial Detect Point, IDP) to the personalized call forwarding service platform. Message

Step 6. The personalized call forwarding service platform plays the voice to the calling terminal (eg, please wait, your call is being connected); Step 7. The personalized call forwarding service platform sends a USSD request to the MSC SERVER B;

Step 8. The MSC SERVER B sends a USSD request to the UE B.

Step 9. UE-B displays a menu on the interface, asking the user to select whether to answer or call;

If the user chooses to call, then execute:

Step 10: The user selects a call and enters a call forwarding number C;

Step 11. The UE-B sends a USSD CONTINUE message to the MSC SERVER B, where the message carries the call number C;

Step 12: The MSC SERVER B forwards the USSD CONTINUE message to the personalized call forwarding service platform, where the message carries the call forwarding number C;

Step 13: The personalized call forwarding service platform sends a CONNECT message to the calling MSC SERVER A, where the message carries the call forwarding number C, indicating the MSC SERVER A connection number C;

Step 14. The MSC SERVER A initiates a call to C.

If the user chooses to answer, then execute:

Step 15. The user selects to answer;

Step 16. UE B sends a USSD CONTINUE message to MSC SERVER B.

Step 17: The MSC SERVER B forwards the USSD CONTINUE message to the personalized paging service platform. Step 18: The personalized paging service platform sends a CONTINUE message to the MSC SERVER A, indicating that the MSC SERVER A continues UE B;

Step 19. The MSC SERVER A initiates a call to UE B.

In the second implementation manner, since the triggering of the call forwarding service occurs when the calling terminal calls the called terminal, the personalized call forwarding service platform is a service control point (SCP) platform called by the called party. It is also a USSD service platform that interacts with the called party through the USSD. The second embodiment provided by the embodiment of the present invention does not require any modification to the existing MSC and the terminal, compared with the first embodiment. It only needs to add one network element, that is, a personalized call service platform, which has less changes to the network, lower cost, and more flexible implementation.
