Description

Implementation method of supporting simultaneous ringing in personal communication services

technical field

The invention relates to a simultaneous ringing technology for multiple called parties in a communication network, in particular to a method for realizing simultaneous ringing in personal communication services.

Background technique

With the development of personal communication, each user has more and more communication tools, such as mobile phones (GSM, CDMA), PHS, fixed-line telephones, etc. Although having multiple communication tools will bring some convenience to the user, each communication tool has a different phone number, which also brings inconvenience to managing numbers, looking up numbers, and remembering numbers.

With the development of the personal communication partner service (one number), the above-mentioned problems have been solved. The user only needs to announce a ONLY number, and all calls to the ONLY number will be automatically connected to the current number (mobile phone, PHS or landline) by the system according to the user's settings.

In the existing personal communication services, the service user is generally asked to provide multiple numbers, and then the system will connect the call to the corresponding number according to established principles, such as user designation and operator rules. For example, the system designates these numbers as the first connection number, the second connection number and the third connection number as the priority order of call connection. When the connection number fails, the call will be transferred to the next connection number. But these numbers do not have essential difference on function and property, the user can set the first connection number as mobile phone or PHS or landline, also can set the second connection number as mobile phone or PHS or landline. The wandering home business is to forcibly transfer the incoming calls on the mobile phone to the fixed line. Although personal communication services bring convenience to users with multiple numbers, they have the following disadvantages:

1. The user needs to set three forwarding numbers through the management process of the personal communication number service (UPT), namely, the first forwarding number, the second forwarding number and the third forwarding number; among each forwarding number, only the current number has no answer, busy When the connection fails, such as routing failure, etc., it will be transferred to the next transfer number, that is, it can only be transferred sequentially.

2. If the user has three options for answering calls at the same time: mobile phone, PHS, fixed phone, and the user wants to use the fixed phone to answer the call, if the priority of the fixed phone is lower than that of the mobile phone and PHS , Just have to wait until the mobile phone, PHS connection fails and can be answered after being transferred to the fixed phone, which will delay the time and cause inconvenience to the user.

3. The wandering home business has caused unhealthy competition among operators and is inconvenient to use.

Although individual small platforms provide two telephone terminals with simultaneous vibration for users to choose to answer through a physical connection (that is, one subscriber line connects two telephones, similar to extensions used at home), but the two telephones cannot communicate, and two or more The physical locations of all synchronous phones need to be close to each other, which will affect the scope of business operations.

Contents of the invention

The purpose of the present invention is to provide a method for realizing simultaneous ringing in personal communication services, so as to solve the problem of inconvenient selection of communication tools to answer calls in existing personal communication services.

In order to solve the above problems, the present invention provides the following technical solutions:

A method for implementing simultaneous ringing in personal communication services, the method comprising steps:

generate a call to a communication partner's service number;

The service control point obtains the priority ringing number and priority forwarding number corresponding to the service number of the communication partner, and sends a connection command to the service switching point for the priority ringing number and priority forwarding number;

The service switching point connects the call to the terminal corresponding to the priority ringing number and the priority forwarding number according to the connection command and makes them ring simultaneously.

in:

The priority forwarding number is the most preferred forwarding number among multiple forwarding numbers.

The terminal corresponding to the priority ringing number rings before the terminal corresponding to the priority forwarding number.

The ringing time of the terminal corresponding to the priority forwarding number is longer than that of the terminal corresponding to the priority ringing number.

When neither the priority ring number nor the priority transfer number is connected, the service control point sends a connection operation to the service switching point again for the priority ring number and the secondary priority transfer number, and the service switching point connects the call Go to the terminal corresponding to the priority ring number and the secondary priority forwarding number and make it ring.

When neither the priority ringing number nor the priority forwarding number is connected, the service control point issues a connection command to the service switching point again for the priority forwarding number and the secondary priority forwarding number than the priority forwarding number, and the service switching point Click to connect the call to the terminal corresponding to the two forwarding numbers and make it ring.

The service control point issues a connection command for the priority ringing number and the priority transfer number, and carries an additional called number in the connection command, the coding method of the additional called number and the destination routing address in the connection operation Encoded in the same way.

Before the service control point issues a connection command to the service switching point, the service control point issues a "request to report basic call control block" operation to the service switching point for the priority ringing number and the priority forwarding number.

Before the service control point issues a connection command to the service switching point, the service control point issues an application for charging to the service switching point for the priority ringing number and the priority forwarding number respectively.

As long as one called party answers, the event report of the basic call control block reported by the service switching point to the service control point is only "answer".

If none of the called parties answers, the service switching point reports to the service control point based on the last reported status of each called party.

The service switching point reports an intermediate charging report to the service control point for each charging application, and the call duration and fee in the charging application report reported by the called party that is not connected are 0.

The present invention has the following beneficial effects:

1. Simultaneous vibration of multiple terminals can facilitate users to choose to use communication terminals to answer incoming calls, which has the advantages of saving phone charges and preventing radiation.

2. Using the signaling link connection to realize the simultaneous vibration of multiple terminals, the voice channel connection is established only after a certain phone is off-hook, so the voice channel resources are not occupied.

3. Set the priority ringing number through the intelligent network, which is not limited by the location of the number, and the setting and use methods are flexible.

Fig. 2 is a flowchart of the present invention.

Detailed ways

Referring to shown in Figure 1, the user's ONLY number is B ', and the user is provided with the first and second numbers corresponding to the user's ONLY number in the database of the service control point (SCP) through the personal communication number service (UPT). and a third diversion number. In addition, the highest priority ringing number (or super number) S corresponding to the one number number is also set, and the number can be set through the management process, SMAP, MML or one-time dialing. The forwarding number can be set according to the needs of the user, such as: the first forwarding number B is the fixed telephone number, the second forwarding number C is the PHS number, and the third forwarding number D is the mobile phone number.

The present invention makes the terminal corresponding to the highest priority ringing number S set by the called user and the transfer number ring simultaneously when the calling user calls the one number number B'. The methods are as follows:

1. The highest priority ringing number S + the first forwarding number B ring at the same time - "the second forwarding number rings -" the third forwarding number rings, that is: when there is an incoming call, the S code set by the user and the first UPT number The forwarding number B rings at the same time. If there is no answer or busy, the second forwarding number rings, followed by the third forwarding number.

If the first forwarding number is not set, the ringing sequence is: the highest priority ringing number S + the second forwarding number C, that is, the highest priority ringing number S always rings together with the set highest priority forwarding number. If the call is not answered, it will be transferred to the subsequent transfer number.

2. The ringing number S with the highest priority—”the ringing number S with the highest priority + the first forwarding number B ringing at the same time—”the ringing number S with the highest priority + the second forwarding number C ringing—”the ringing number S with the highest priority + the first forwarding number B Three diversion number D rings.

That is: the S code rings first, and when there is no answer or the called party is busy, then the S code and each transfer number ring together in turn.

3. Simultaneous ringing of the highest priority ringing number S + first forwarding number B —” simultaneous ringing of the first forwarding number B + second forwarding number C—”simultaneous ringing of the second forwarding number + third forwarding number D.

That is: at first the most priority ringing number S and the first transfer number B ring simultaneously, wherein the ringing time of the first transfer number B is longer than the ringing time of the most priority ringing number S (so that there are The ringing time of a number is prolonging, avoiding the problem that the user can't answer in time.); If there are reasons such as not answering or being busy, then the first transfer number B and the second transfer number C ring simultaneously, and so on.

When realizing the simultaneous vibration of terminals corresponding to multiple numbers, although there are multiple called parties, the service control point (SCP) only issues a request to report the basic call control block (RRBE) operation; issues an application for charging for each called number (ApplyCharge, AC) operation, and issue a connection (Connect) operation to all called numbers.

The BCSM event report (ERB) event received at the service control point (SCP) side is the state to be displayed to the calling party after the service switching point (SSP) analyzes the states of each called party. As long as one called party answers, no matter whether the other called party fails to select the route, the called party is busy or does not answer, the SSP will only report the response (oAnswer) event to the SCP. If no oAnswer event is configured, no event will be reported; if there is no If the called party responds, it will be reported to the SCP based on the last reported status of each called party, such as: there are 3 called parties in total, one route selection failure, one called party busy, and one non-response (there may be multiple EDP events, SSP report the detected last EDP event to the SCP), the SSP only reports no response to the SCP.

During the call, the SSP will report the intermediate charging report (HeartBeat-ACR) for each application charging (AC), and the call duration and cost in the application charging report (ApplyChargeReport, ACR) reported by the called party that is not connected If it is 0, the start time and end time of the call are both equal to the start time of the called party that is actually connected. After the call ends, ACR is reported for each AC. For calls that are not connected, the information in the final ACR is basically the same as that of the heartbeat ACR, except that the reason for the report is the same as that reported by the called party that is actually connected.

Since the connection (Connect) operation supports carrying an additional called number, in the present invention, the Coupect operation is expanded to add an additional called number. Each additional called number is encoded in the same manner as the destination routing address in the Connect operation. If there is no additional called number, the entire "additional number" structure is not encoded. The additional called numbers are coded sequentially from the first one, and the n+1th additional called number shall not be coded without skipping the nth additional called number. If there is no additional number, the simultaneous oscillation delay parameter is not encoded. If the service does not specify the simultaneous oscillation delay, the simultaneous oscillation delay parameter is not encoded. If neither the additional number nor the simultaneous oscillation delay parameter exists, the whole extended item is not coded.

Referring to Figure 2, the signaling process for realizing simultaneous ringing of two terminals is as follows:

Step 1. Dial the access code, trigger an intelligent call on the SSP, and the SSP reports the IDP to the SCP side of the intelligent network. Wherein, the called number in Initial DP(A, B′) is the number B′ disclosed by the user to the public.

Step 2. Trigger the service process on the SCP, and the SCP sends the monitoring event RRBE to the SSP.

Step 3, the service on the SCP obtains the highest priority ringing number S and the first forwarding number B registered by the user from the database, and issues an application charge (ApplyCharge) to the SSP for these two numbers (including step 3-1 , 3-2).

The "called number" in ApplyCharge is B', and the "destination numbers" are B and S respectively. The service modifies the system CID----S_DestinationAddr (destination address number) to realize that the "destination number" in the second AC is S.

Step 4. The SCP sends a Connect command to the SSP, and the SSP connects to the terminal corresponding to the number B and the number S after receiving the command, so that the two terminals ring at the same time. Add an additional called number S in the Connect operation.

Step 5. During the call, the SSP reports an intermediate charging report (HeartBeat-ACR) for each application charging (ApplyCharge). The call duration and charge in the application charging report (ApplyChargeReport) reported by the called party that is not connected are 0, and the start time and end time of the call are equal to the start time of the called party that is actually connected.

Step 6. After the call ends or there is no call, the SSP reports the charging report and EDP event to the SCP (including steps 6-1, 6-2, and 6-3).

After the call ends, ACR is reported for each AC. For calls that are not connected, the information in the final ACR is basically the same as that of the heartbeat ACR, except that the reason for the report is the same as that reported by the called party that is actually connected.

Step 7. The SCP issues a Release Call (ReleaseCall) command to the SSP.

The simultaneous ringing realization process for the highest priority ringing number S and the priority forwarding numbers C and D is the same as the above process.
