Description
Technical Field
The present invention relates to a method and a system for implementing one-number service, and more particularly, to a method and a system for implementing one-number service in a Next Generation Network (NGN).
Background
Universal Personal Telecommunications (UPT), also known as Universal Personal communications, is a value-added Telecommunication service proposed to meet the personalized communication requirements of users. The one-number telephone adopts a single one-number telephone number to uniformly manage office telephones, home telephones, GSM mobile phones, CDMA mobile phones, personal handyphone phones and the like of users, and allows the users to independently set communication numbers and other related parameters of the terminals. The user can realize free communication of fixed telephones, mobile phones, personal handphone systems and the like only by externally publishing a uniform one-number communication number, and really realizes random communication number replacement and random answering selection. The one-number service can be divided into two functions of one-number simultaneous ringing and one-number sequential ringing.
The one-number-one-number simultaneous ringing function can set the one-number-one-number to correspond to a plurality of terminals, a user only needs to publish the one-number-one-number of the user, when a call dials the one-number-one-number, the plurality of terminals ring at the same time, after any one terminal is off-hook and answered, the call enters a conversation state, and other terminals stop ringing and are disconnected.
The one-number-pass sequential ringing function can set a plurality of communication numbers, a user only needs to publish the own one-number-pass number, when the one-number-pass number is dialed by a telephone, the first communication number is called firstly according to the setting of the user, if the first communication number is busy or no one answers, the second communication number is switched to, if the second communication number is busy or no one answers, the third communication number is switched to, and the like.
As shown in fig. 1, the system diagram for implementing the one-number service in the prior art is mainly applied to the existing fixed telephone network, and the one-number service is implemented by an intelligent network platform. The system comprises: the method comprises the steps that a Home Location Register (HLR), a Service Switching Point (SSP), a Service Control Point (SCP), a calling user, a called user and a binding user signed by the called user, wherein the SSP is respectively connected with the HLR and the SCP, the calling user, the called user and the binding user signed by the called user are connected with the SSP through a ground end office, the HLR is responsible for storing user information, the SSP is responsible for inquiring whether the user signs a one-number Service and triggering the one-number Service, and the SCP is responsible for controlling the implementation process of the one-number Service and storing the communication number of the one-number Service and the communication number of the binding user.
The following describes an existing method for implementing the one number service by taking the one number service simultaneous ringing function as an example, wherein a user a as a calling user calls a user B as a called user, the method includes the following steps:
firstly, a user A dials the number of a user B;
secondly, after receiving the call request sent by the user A, the SSP judges whether the user B is a one-number user by inquiring the HLR, if the user B is not the one-number user, the SSP directly initiates a call to the user B, and the method is finished.
Thirdly, SSP sends user B number to SCP to trigger user B one number service;
fourthly, SCP sends attribute information of user B, communication number of user B and communication number of co-vibration binding user signed by user B to SSP;
here, taking the example that the user B signs the contract of the co-vibration binding user C, the SCP issues the communication number of the user B and the communication number of the signed co-vibration binding user C to the SSP.
Fifthly, the SSP sends a call message to the user B and the floor end office of the signed resonance binding user at the same time, and the floor end office sends the call message to the user B and the signed resonance binding user;
here, the SSP initiates a call to user B and its subscribed co-ringing bound user C.
Step six, SSP sends ring back tone or prompt tone to user A according to SCP indication or preset setting;
seventhly, after any current called user answers, SSP completes normal connection, and removes the call to other communication numbers according to the indication of SCP or the preset setting, and the method is finished.
If the synchronous ringing binding user C answers, the SSP connects the user A and the synchronous ringing binding user C to complete normal connection, and meanwhile, the SSP removes the call to the user B according to the indication or the preset setting of the SCP.
The one-number service has the greatest advantages that convenience is brought to daily work and life of users, such as solving the problem of telephone busy and ensuring smooth communication; for example, only one-number-pass numbers can be printed on the business cards in daily traffic, and a large series of numbers such as mobile numbers, office numbers, house numbers, little smart numbers and the like do not need to be printed on the business cards, so that the inconvenience caused by the number change of the user and the memory of a plurality of numbers by the opposite party is avoided; similarly, when the telephone number is changed, the trouble of informing relatives and friends one by one can be saved; for business people, it is very important not to miss any phone; if the user frequently goes on a business trip, the user can set the answering telephone as a foreign mobile phone or a fixed telephone number, and long-distance transfer or cross-border transfer can be easily realized.
Although the one number service has many advantages, in practical application, the popularization of the one number service is far from reaching the expected effect of people. At present, a typical method for implementing the one-number service is to implement the one-number service through an intelligent network platform in the existing fixed telephone network, however, this method involves more network elements, has a wider scope of equipment modification, a more complex technical implementation, a larger investment, and a limited processing capability of SSP, and if the intelligent network platform itself fails or the communication between the fixed telephone network and the intelligent network platform is abnormal, the normal use of the one-number service may be affected. However, the NGN network with high processing capability cannot realize the one-number service at present.

as shown in fig. 3, a flowchart of a method for implementing a one number service according to the present invention when the function is a simultaneous ringing function is shown, the method includes the following steps:
step 301: calling user A dials the number of called user B;
the terminal types of the calling user a and the called user B are not limited to Public Switched Telephone Network (PSTN) users, but may also be Session Initiation Protocol (SIP) users, H248 users, H323 users, Integrated Services Digital Network (ISDN) users, and the like, within or outside a control domain of an NGN Network control device.
Step 302: after receiving the call request, the NGN network control equipment queries an internal core database to obtain subscription information of a called user B;
the NGN network control equipment can inquire the subscription information of the called user B by sending an inquiry message to the internal core database, wherein the inquiry message needs to contain the number of the called user B; the subscription information of the called subscriber B can also be obtained by querying the HLR.
Step 303: and the NGN network control equipment reads the returned subscription information of the called user B, judges whether the called user B is a one-number user, and directly calls the called user B if the called user B is not the one-number user, and the method is finished.

step 305: the NGN network control equipment judges that the called user B is a one-number-through simultaneous ringing user, and acquires the one-number-through signed communication number of the called user B from the read signed information of the called user B;
in this embodiment, taking an example that the called subscriber B signs a simultaneous ringing binding subscriber C, the one-number-only signed communication number of the called subscriber B includes: and the communication number of the called user B and the communication number of the co-vibration binding user C.
The number of the called user B dialed by the calling user a may be a communication number of the called user B, or a one-number dedicated number segment, etc. The former mode is adopted in the embodiment, and no matter which mode is adopted, the implementation of the system and the method for implementing the one-number service provided by the invention is not influenced.
Step 306: the NGN network control equipment simultaneously sends a calling message to a called user B and a floor end office of a co-vibration binding user, and the floor end office sends the calling message to the called user B and a terminal of the co-vibration binding user and sends back respective ring back tones;
in this embodiment, the NGN network control device initiates a call to the called user B and the simultaneous ringing binding user C at the same time;
if an idle user and a busy user exist in the called users of the current call at the same time, the NGN network control device removes the call to the busy user and only calls the idle user.
Step 307: NGN network control equipment sends a ring back tone or a prompt tone to a calling subscriber A in a unified way;
at this time, the called user B and the co-vibration bound user C ring at the same time, and their respective floor end offices all return their own ring back tones or warning tones, but for the calling user a, these ring back tones or warning tones should not be heard at the same time, the NGN network control device controls to broadcast only the ring back tone or warning tone of the called user B, or only the ring back tone or warning tone of the co-vibration bound user C, or only other unique ring back tone or warning tone to the calling user a.
Step 308: if the called user B and any one of the co-vibration binding users answer, the NGN network control equipment communicates the calling user A and the answering terminal to complete normal connection, and meanwhile, the calls to the other unanswered terminals are removed, and the method is finished. If the called user B and the terminal of the co-vibration binding user can not be connected with the calling user A, the NGN network control equipment removes the call of the calling user A to the called user B and the co-vibration binding user, the call fails, and the method is ended.

The reason that the calling subscriber a, the called subscriber B and the terminal of the simultaneous ringing binding subscriber cannot be connected is that: the called user B and the synchronous ringing binding user are busy or have no response.
The second preferred embodiment:
as shown in fig. 4, a flowchart of a method for implementing a one number service according to the present invention when the function is a forward vibration function, the method includes the following steps:
step 401: calling user A dials the number of called user B;
the terminal types of the calling user A and the called user B are not limited to PSTN users, and can be SIP users, H248 users, H323 users, ISDN users and the like in the control domain of the NGN network control equipment or outside the control domain.
Step 402: after receiving the call request, the NGN network control equipment queries an internal core database to obtain subscription information of a called user B;
the NGN network control equipment can inquire the subscription information of the called user B by sending an inquiry message to the internal core database, wherein the inquiry message comprises the number of the called user B; the subscription information of the called subscriber B can also be obtained by querying the HLR.
Step 403: and the NGN network control equipment reads the returned subscription information of the called user B, judges whether the called user B is a one-number user, and directly calls the called user B if the called user B is not the one-number user, and the method is finished.
In this embodiment, the called subscriber B is a one-number user.
Step 404: the NGN network control equipment reads the subscription information of the called user B, and judges whether the called user B is a one-number simultaneous ringing user or a one-number sequential ringing user according to the subscription information;
step 405: the NGN network control equipment judges that the called user B is a one-number-pass order ringing user, and acquires the one-number-pass signing communication number of the called user B from the read signing information of the called user B;
the one-number-through signed communication number of the called user B sets a priority order according to the requirement of the user when an internal core database is configured. The priority level may be indicated in different manners, such as sorting the communication numbers of the user according to a priority order, or adding a priority identification bit to the communication numbers of the user.
The number of the called user B dialed by the calling user a may be a one-number-through dedicated number segment, or may be a communication number of the called user B. The latter mode is adopted in the embodiment, and no matter which mode is adopted, the implementation of the system and the method for implementing the one-number service provided by the invention is not influenced.
Step 406: the NGN network control equipment sends a calling message to a floor end office of a user with the highest priority according to the priority of the acquired one-number-communication signed communication number, and the floor end office sends the calling message to the terminal of the user and sends back a corresponding ring back tone;

in this embodiment, the terminal of the called subscriber B does not respond, and the NGN network control device removes the call to the called subscriber B and determines that the next called subscriber exists.
The NGN network control device may determine whether the next called user exists in multiple ways, for example, after acquiring the one-number-one-pass signed communication number of the called user B, the NGN network control device counts the number of the acquired one-number-one-pass signed communication numbers, stores the counted result in a counter, performs a subtraction of 1 operation on the counter after completing a call, and if the value recorded in the counter is subtracted to 0, it indicates that the next called user does not exist.
Step 409: the NGN network control equipment sends a call message to a floor end office of a next called user according to the priority of the acquired one-number-communication signed communication number, and the floor end office sends the call message to the terminal of the current called user;
in this embodiment, the priority of the forward-ringing binding user C subscribed by the called user B is only next to that of the called user B, and the NGN network control device initiates a call to the forward-ringing binding user C.
Step 410: NGN network control equipment sends a ring back tone or a prompt tone to a calling subscriber A, if the current called subscriber answers by picking up, the calling subscriber A and the current called subscriber are connected, normal connection is finished, and the method is finished.
In this embodiment, the terminal of the forward vibration binding user C answers the call, the NGN network control device connects the terminal of the calling user a and the terminal of the forward vibration binding user C to complete normal connection, and the method ends.

Step 502: after receiving the call request, the NGN network control equipment queries an internal core database to obtain subscription information of a called user B;
the NGN network control equipment can inquire the subscription information of the called user B by sending an inquiry message to the internal core database, wherein the inquiry message needs to contain the number of the called user B; the subscription information of the called subscriber B can also be obtained by querying the HLR.
Step 503: and the NGN network control equipment reads the returned subscription information of the called user B, judges whether the called user B is a one-number user or not according to the subscription information, and directly calls the called user B if the called user B is not the one-number user, thus the method is finished.
Step 504: the NGN network control equipment reads the subscription information of the called user B, and judges whether the called user B is a one-number simultaneous ringing user or a one-number sequential ringing user according to the subscription information;
step 505: the NGN network control equipment judges that the called user B is a one-number-pass sequential-ringing user, and acquires a one-number-pass signing communication number of the called user B from the signing information of the called user B, wherein the signing information of the called user B only comprises one-number-pass signing communication number;
one-number-pass signed communication number included in the subscription information of the called subscriber B is the communication number of the subscriber with the highest priority, and in this embodiment, the priority of the called subscriber B is the highest.
The number of the called user B dialed by the calling user a may be a one-number-through dedicated number segment, or may be a communication number of the called user B. The latter mode is adopted in the embodiment, and no matter which mode is adopted, the implementation of the system and the method for implementing the one-number service provided by the invention is not influenced.
Step 506: the NGN network control equipment sends a call message to a floor end office of the obtained communication number, and the floor end office sends the call message to the terminal of the current called user and sends back a corresponding ring back tone;
in this embodiment, the NGN network control device first initiates a call to the called user B.
Step 507: NGN network control equipment sends a ring back tone or a prompt tone to a calling subscriber A;
in this embodiment, the NGN network control device controls the transmission of the ring back tone or the alert tone of the current called subscriber, or only other unique ring back tone or alert tone, to the calling subscriber a.
Step 508: if the terminal of the current called user answers, the NGN network control equipment communicates the calling user A and the terminal of the current called user to complete normal connection, and the method is finished; otherwise, the NGN network control equipment removes the terminal call to the current called user, and inquires the internal core database of the NGN network control equipment again to obtain the one-number-pass signed communication number of the called user B;
the NGN network controller can send a query message to the internal core database to query the one-number-communication signing communication number of the called user B, wherein the query message comprises the number of the called user B and the one-number-communication signing communication numbers of the previous calls or the previous calls;
step 509: the NGN network control equipment judges whether the message returned by the internal core database contains the one-number-service sign-on communication number of the called user B, if so, the step 506 is skipped, otherwise, the calling is failed, and the method is ended.
