Description

A method and system for realizing one number service

technical field

The technical field of the mobile communication network of the present invention, in particular, relates to a method and system for realizing one number service.

Background technique

With the development of mobile communication technology, the integrated one number service based on CM-IMS (Chinamobile IP Multimedia System, China Mobile IP Multimedia Subsystem) has been greatly developed. IMS service means that the user applies to China Mobile, sets a mobile phone number or IMS terminal number (TelURI) as the main number of the service, and can set one to three mobile phone numbers or IMS terminal numbers as the binding number for outgoing calls. Fixed number and binding number for incoming calls, realizing incoming caller display as primary number for outgoing calls, binding terminal simultaneous or sequential ringing services for CS (Circuit Switched, circuit switched) domain and IMS domain fusion services for incoming calls. The mobile phone here can be a GSM mobile phone or a TD-SCDMA (TimeDivision-Synchronous CodeDivision Multiple Access, Time Division Synchronous Code Division Multiple Access) mobile phone.

In the One Number Outgoing service, when a user initiates a call using the integrated One Number main number or any bound number for outgoing calls, the called terminal's caller ID should be the main number (the number of the mobile phone or IMS terminal).

In the One Number Call service, the user can set the ringing mode for the main number to answer the call. When the main number is called, the main number terminal and all associated number terminals can be selected to ring simultaneously or simultaneously according to the user's settings. Sequential ringing (the sequence can be specified by the user).

The main number of the converged One Number Service service is aimed at the mobile phone users and IMS users of China Mobile, and the number bound when making an outgoing call is the mobile phone number and IMS number of China Mobile in the same province (or municipality directly under the Central Government) as the main number. The bound number for incoming calls must include the bound number for outgoing calls, and you can also refer to the forwarding service to set other bound numbers for incoming calls.

China Mobile has already opened the converged V network group to use the converged one number service to realize the following business scenarios:

Fixed-line called one number service: CM-IMS fixed-line opened called called one-number service, to realize the resonance of the associated number (mobile phone number) when the fixed-line (primary number) is called. This service has no restrictions on the calling number.

The signaling process 1 of its realization principle (the ordinary user in the CS domain dials the CM-IMS fixed-line called one number user) is shown in Figure 1, where A is the number of an ordinary user in the CS domain; B is the number of the one number user in the IMS domain Main number; B' is the associated number of the ONLY user, which may be an IMS domain or a CS domain. The specific process is as follows:

(1) The CS domain user UE_A dials the primary number B of the IMS domain ONLY user;

(2), MSC_a (Mobile Switching Center, Mobile Switching Center) routes the call to MGCF (Media Gateway Control Function);

(3), MGCF calls into IMS domain, sends to CSCF (call session control function);

(4) The CSCF triggers the ONLY application server according to the iFC rule of the ONLY user. AS (Application Server, application server) finds the ringing list of the ONLY user and the ringing mode is simultaneous ringing or sequential ringing;

In Sequential mode:

(5) Assuming that the order of the sequential vibration set by the user is B' first and then B, B' may be the IMS domain or the CS domain;

(6), B' fails to connect and returns a 4XX message; AS continues to connect to B, and CSCF routes the call request to B to B;

(7) B returns a 200 OK response message, B responds normally, and the call between A and B is established.

In the synchronous mode:

(8), the one number AS initiates the call to B and B' at the same time;

(9), assuming that the answer of B comes back first (the routing process is the same as the routing process under the sequential vibration mode), AS releases the call to B', and sets up the call to B.

As shown in Figure 2, it is a schematic diagram of the signaling process 2 (the ordinary user in the IMS domain dials the CM-IMS fixed-line called one number user) service diagram, where A is the number of an ordinary user in the CS domain; B is the one number user in the IMS domain Main number; B' is the associated number of the ONLY user, which may be an IMS domain or a CS domain. The specific process is as follows:

(1), IMS domain user A dials the primary number B of the IMS domain ONLY user;

(2) The CSCF triggers the call to the AS for processing according to the data signed by the ONLY user;

In Sequential mode:

(3) Assume that the order of sequential oscillation set by the user is B first and then B', B' may be the IMS domain or the CS domain;

(4), B fails to connect, and returns a 4XX message; AS continues to connect to B', and CSCF routes the call request to B' to the corresponding domain (may be IMS, may be);

(5), B' returns a 200OK response message, B' responds normally, and the call between A and B' is established.

In the synchronous mode:

(6), the one number AS initiates calls to B and B' at the same time;

(7), assuming that the response of B' comes back first (the routing process is the same as the routing process in the sequential vibration mode), the AS releases the call to B and sets up the call to B'.

In the mobile phone called one number service, the mobile phone activates the anchoring function on the intelligent network SCP and the called one number function on the IMS system, so as to realize the resonance of the associated number with the mobile phone number when it is called. There are no restrictions on calling numbers.

The signaling process 1 of its realization principle (the ordinary user in the CS domain dials the mobile phone and the called one number user) is shown in Figure 3, wherein, A is the common user number in the CS domain; B is the main number of the one number user in the IMS domain; 'is the associated number of the ONLY user, which may be an IMS domain or a CS domain. The specific process is as follows:

(1), CS domain user A dials the primary number B of the CS domain ONLY user;

(2), MSC_a triggers the call to the SCP for processing according to the subscription data of the ONLY user B;

(3) The SCP sends a CONNECT message to anchor the call to the IMS domain. The destinationRoutingAddress in the Connect message=RN+B (B is an 11-digit mobile phone number without 86 or +86);

(4), MSCa maps the destinationRoutingAddress in the Connect message to the CalledPartyNumber in the IAM message, and points the route to MGCF;

(5), MGCF deletes the RN in CalledPartyNumber after receiving the IAM message, and maps the B number to Request URI and To label (during number mapping, the B number should be mapped to the standard international code format of +86), and then Initiate an Invite request, connect the call to the IMS domain, and send it to the CSCF;

(6) The CSCF triggers the converged ONLY application server (AS module) according to the iFC rule of B. The AS looks up the ringing list of the ONLY user and the ringing mode is simultaneous ringing or sequential ringing.

Shun vibration mode:

(7), first connect to B', B' answers timeout and is released;

(8) Then connect to B, because B is a CS user, in order to avoid B from performing secondary business processing on the SCP in the CS domain, the ONLY AS is required to make special settings for the relevant number in the Invite request to initiate a call to B (PAI=Prefix2+A, From=A, Request-URL=Prefix1+B), then route the call to MGCF;

(9), GMSC triggers to the SCP, finds that there is a prefix code in front of the corresponding A number in the CallingPartyNumber, does not perform secondary processing, and deletes the prefix code of A, and then sends CONNECT (where GenericNumber=A, QUALIFY corresponding to GN Field is 80H) message, initiates a call to B;

(10), B answers, and A talks with B.

Simultaneous vibration mode:

(11), the one number AS initiates the call to B and B' simultaneously, and wherein to B's call processing flow of this way is the same as the sequential vibration mode;

(12), assuming that the answer of B comes back first (the routing process is the same as the routing process under the oscillating mode), AS releases the call to B', and sets up the call to B;

(13), the call between A and B is established.

As shown in Figure 4, it is a schematic diagram of the signaling process 2 (the ordinary user in the IMS domain dials the mobile phone and the called one number user) service diagram, wherein, A is the common user number in the CS domain; B is the main number of the one number user in the IMS domain; 'is the associated number of the ONLY user, which may be an IMS domain or a CS domain. The specific process is as follows:

(1), IMS domain user A dials the primary number B of the CS domain ONLY user;

(2) The CSCF triggers the ONLY service AS according to the iFC rule of the ONLY user B. The AS looks up the ringing list and ringing mode of the ONLY user, which may be sequential ringing or simultaneous ringing;

In Sequential mode:

(3) Assume that the sequential vibration sequence set by the user is B' first and then B. B' may be an IMS domain or a CS domain. The ONLY AS first initiates a call to B';

(4), B' failed to connect, and returned a 4XX message; AS continued to connect to B, because B is a CS user, in order to prevent B from performing secondary service processing on the SCP in the CS domain, the ONLY AS is required to initiate a call to B In the Invite request, make special setting (PAI=Prefix2+A, From=A, Request-URL=Prefix1+B) to relevant number, then route the call to MGCF;

(5), the MGCF deletes the called prefix prefix2, routes the call to the GMSC, queries the HLR, and triggers the call to the SCP for processing;

(6), according to the reported IDP message in the CallingPartyNumber corresponding to the A number in front of the pre-insert code, without secondary processing, and delete the pre-inserted code of A, and then send CONNECT (where Generic Number=A, GN corresponds to QUALIFY field is 80H) message, initiates a call to B;

(7), B answers normally, and the call between A and B is established.

In the synchronous mode:

(8), One Number AS initiates calls to B and B' at the same time, wherein the call processing flow to B is the same as the sequential vibration mode;

(9), assuming that the answer of B comes back first (the routing process is the same as the routing process under the sequential vibration mode), AS releases the call to B', and sets up the call to B;

(10), the call between A and B is established.

In the one number service for fixed-line calling, CM-IMS fixed-line service activates the one-number service for calling, so that when the fixed-line phone is used as the calling party, the called side will display its primary number.

The signaling process 1 of its realization principle (CM-IMS fixed-line calling One Number User dials a CS domain common user) is shown in Figure 5, where A is the CS domain common user number; B is the IMS domain One Number Tong user Main number; B' is the associated number of the ONLY user, which may be an IMS domain or a CS domain. The specific process is as follows:

(1), the IMS domain one number number user UE_A dials the CS domain common user number B;

(2) The CSCF triggers the call to be processed on the AS according to the data signed by the calling number;

(3), the number display (From header field and PAI header field) of the calling number is modified by the AS to be the main number of the ONLY user;

(4) The CSCF initiates a subsequent CS domain call process;

(5) The common user UE_B in the CS domain rings, and the incoming call shows the primary number A` of the ONLY user.

As shown in Figure 6, it is a schematic diagram of the signaling process 2 (the CM-IMS fixed-line caller calls the IMS domain common user) business diagram, wherein, A is the CS domain common user number; B is the IMS domain One Number Connect user Main number; B' is the associated number of the ONLY user, which may be an IMS domain or a CS domain. The specific process is as follows:

(1), the IMS domain one number number user UE_A dials the IMS domain common user number B;

(2) The CSCF triggers the call to be processed on the AS according to the data signed by the calling number;

(3), the AS modifies the calling number (From domain and PAI domain) as the main number of the ONLY user;

(4), CSCF initiates the subsequent IMS domain call process;

(5) The common user UE_B in the IMS domain rings, and the incoming call shows the primary number of the ONLY user.

To sum up, the existing integrated ONLY service attributes cannot meet the needs of group customers who have opened the integrated V-network. The specific manifestations are: after a phone outside the group dials the main number of the called ONLY number, the scenario realized by the existing technical solution is as follows: The IMS fixed line and mobile phone resonate, but the customer requires no resonance for calls outside the group. When an IMS fixed-line phone dials a number outside the group, the implementation scenario of the existing technical solution is that the called party displays its main number (mobile phone number), and when the customer requests to dial a number outside the group, its real number (IMS fixed-line number) is displayed.

detailed description

Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, the embodiments of the present invention are not limited thereto.

The principle of the embodiment of the method of the present invention is that the converged ONLY service is realized by the service on the unified Centrex side, so the implementation of the above solution needs to be analyzed on the unified side Centrex. This service is implemented by adding a special identification field to the group user table in the AS database to distinguish whether the ONLY function is triggered within the group or outside the group. The unified Centrex service analyzes the fields of the group user table and controls the triggering of the service to meet the requirements of the fusion V Network customers use the converged one number service. Specifically, by modifying the structure of the group user table, a GroupCallingFlag (group calling number one number special processing flag) is added, which is used to identify the triggering of calling the number one number number within the group and outside the group. Added GroupCalledFlag (group called one number special processing flag), which is used to identify the trigger of calling one number within the group and outside the group.

As shown in FIG. 7 , it is a flowchart of the principles of the one number service implementation method provided by Embodiment 1 of the present invention, specifically as follows:

Step 10, when the primary number of the ONLY user is used as the calling/called user, it is judged whether the called/calling number at the opposite end is a number within the group, if so, go to step 20; otherwise, go to step 30.

The ONLY user here refers to the user who has opened the ONLY service. As mentioned above, after opening the ONLY service, the user can set a main number as the calling/called display number to facilitate multiple Unity between numbers. Usually, in the ONLY service, the calling/called parties are all based on the primary number of the ONLY user. When the primary number of the ONLY user is used as the calling/called user, it is first necessary to determine whether the called/calling number of the opposite end is a number within the group. The intra-group number here is set by the ONLY user, and usually refers to the user number within the same VIP customer business group, or other numbers set by the ONLY user. Of course, it can also be set here by the communication operator according to the application of the one number number user.

Step 20, triggering the service flow set by the One Number Call user to connect the call.

When it is determined that the ONLY user has set an intra-group number, and the called/calling number of the opposite end is an intra-group number, it means that the call is an intra-group call, which conforms to the characteristics set by the ONLY service, and a one-number service can be triggered. The business process set by the number pass user to connect the call. The usual setting is that when the primary number of the ONLY user is used as the called user, the ONLY primary number and the associated number will ring at the same time; when the primary number of the ONLY user is the calling user, modify The calling number in the caller ID is the associated primary number.

Step 30, triggering the normal call service flow to connect the call.

When the opposite end number is not a number in the group, trigger the normal call service process to connect the call, that is, trigger the call process according to the non-one number service. Generally speaking, when the main number of the ONLY user is used as the called party, only the main number of the ONLY user is ringing; when the main number of the ONLY user is used as the calling user, the caller ID of the called number The real number of the calling number is displayed in .

Further, before the above solution, a process of judging whether the user is a ONLY user is required. When it is judged that the calling/called user is an ONLY user, step 10 is executed, and subsequent processes are sequentially executed. Otherwise, the calling/called user is not an ONLY user, and the normal call service process is directly triggered to connect the call.

Furthermore, before the above-mentioned solution, a process of judging whether the ONLY user has set up different triggering call procedures for users inside and outside the group, if so, execute step 10, and execute the subsequent procedures sequentially. Otherwise, it means that the user is just an ordinary ONLY user, and the service process set by the ONLY user is directly triggered to connect the call.

As mentioned above, whether the ONLY user has set up the call process for different users inside and outside the group needs to be done by modifying the structure of the group user table, and adding the special processing flag GroupCallingFlag for group calling ONLY, which is used to identify calling ONLY The trigger is based on the difference between inside and outside the user group; add the GroupCalledFlag, which is a special processing flag for the group called ONLY, which is used to identify the trigger for distinguishing between inside and outside the called ONLY user group. By reading the status of the GroupCallingFlag and/or GroupCalledFlag flags in the group user table, it is determined whether the ONLY user has set the call process to be triggered differently for users inside and outside the group.

In order to facilitate the understanding of the embodiment of the present invention, the specific implementation principle and process of the embodiment of the present invention will be described below by distinguishing different processes in which the ONLY user is called/calling.

Firstly, the structure of the group user table is modified, and the GroupCallingFlag (group calling number one number special processing flag) is added, which is used to identify the triggering of calling the number one number number within the group and outside the group. Added GroupCalledFlag (group called one number special processing flag), which is used to identify the trigger of calling one number within the group and outside the group. The specific code example is as follows:

ALTER TABLE Ctx_Group ADD(GroupCallingFlag CHAR(1) DEFAULT '0');

ALTER TABLE Ctx_Group ADD(GroupCalledFlag CHAR(1) DEFAULT'0');

Update ctx_group set GroupCallingFlag=1 where vpnid='306536';

Update ctx_group set GroupCalledFlag=1 where vpnid='306536'.

As shown in FIG. 8 , it is a flow chart of the principle when the ONLY user acts as the called party, wherein the calling user dials the called ONLY primary number. The IMS core network triggers the called process to the AS for processing according to the trigger data. The AS first analyzes the group attribute of the ONLY number, and judges whether the group user table has a special identification bit field. Then analyze whether the calling and called numbers are in the same group, and if they are in the same group, it will trigger the One Number Call main number and the associated number to ring at the same time. If the calling number and called number are not in the same group, the calling number will be ringed directly, and the associated number will not be ringed.

As shown in Figure 9, it is a schematic diagram of the one number service of a common user in the CS domain dialing a CM-IMS fixed line, where A is the number of a common user in the CS domain; B is the main number of the one number user in the IMS domain; B' is The number associated with the ONLY user may be an IMS domain or a CS domain. The specific process is as follows:

(1) The CS domain user UE_A dials the primary number B of the IMS domain ONLY user;

(2), MSC_a routes the call to MGCF;

(3) The MGCF connects the call to the IMS domain and sends it to the CSCF;

(4) The CSCF triggers the ONLY application server according to the iFC rule of the ONLY user.

(5), AS according to the value of GroupCalledFlag in the group user table of the main AS database is equal to 1 and the calling and called numbers are not in the same group, directly connect to B, do not connect to B', and the call between A and B is established.

As shown in Figure 10, it is a schematic diagram of the service diagram of an ordinary user in the MS domain dialing a CM-IMS fixed-line called ONLY user service, wherein, A is the number of an ordinary user in the CS domain; B is the main number of the ONLY user in the IMS domain; B' is The number associated with the ONLY user may be an IMS domain or a CS domain. The specific process is as follows:

(1), IMS domain user A dials the primary number B of the IMS domain ONLY user;

(2) The CSCF triggers the call to the AS for processing according to the data signed by the ONLY user;

(3) According to the value of GroupCalledFlag in the group user table of the main AS database equal to 1 and the calling and called numbers are not in the same group, the AS directly connects to B, does not connect to B', and the call between A and B is established.

As shown in Figure 11, it is a schematic diagram of the one number service of a common user in the CS domain calling a mobile phone, where A is the number of a common user in the CS domain; B is the main number of the one number user in the IMS domain; B' is the one number user The associated number may be an IMS domain or a CS domain. The specific process is as follows:

(1), CS domain user A dials the primary number B of the CS domain ONLY user;

(2), MSC_a triggers the call to the SCP for processing according to the subscription data of the ONLY user B;

(3) The SCP sends a CONNECT message to anchor the call to the IMS domain. The destinationRoutingAddress in the Connect message=RN+B (B is an 11-digit mobile phone number without 86 or +86);

(4), MSCa maps the destinationRoutingAddress in the Connect message to the CalledPartyNumber in the IAM message, and points the route to MGCF;

(5), MGCF deletes the RN in CalledPartyNumber after receiving the IAM message, and maps the B number to Request URI and To label (during number mapping, the B number should be mapped to the standard international code format of +86), and then Initiate an Invite request, connect the call to the IMS domain, and send it to the CSCF;

(6) The CSCF triggers the converged ONLY application server (AS module) according to the iFC rule of B.

(7), AS is equal to 1 according to the value of GroupCalledFlag in the group user table of the main AS database and the calling and called numbers are not in the same group, directly connects to B, does not connect to B', and the call between A and B is established.

As shown in Figure 12, it is a schematic diagram of an IMS domain ordinary user dialing a mobile phone called ONLY user service, wherein, A is the CS domain ordinary user number; B is the IMS domain ONLY user primary number; B' is the ONLY user The associated number may be an IMS domain or a CS domain. The specific process is as follows:

(1), IMS domain user A dials the primary number B of the CS domain ONLY user;

(2) The CSCF triggers the ONLY service AS according to the iFC rule of the ONLY user B.

(3) According to the value of GroupCalledFlag in the group user table of the main AS database equal to 1 and the calling and called numbers are not in the same group, the AS directly connects to B, does not connect to B', and the call between A and B is established.

On the other hand, if the ONLY user is the calling user, the specific process is shown in FIG. 13 , in which the IMS fixed-line calling for ONLY calling is activated. The IMS core network triggers the calling process to the AS for processing. AS first analyzes the group attribute, and the group user table has a special identification bit field. Then analyze whether the calling and called numbers are in the same group, and in the same group, modify the display of the called number according to the ONLY service, and change the calling number to its associated main number. If the calling number and called number are not in the same group, the real number of the calling number will be displayed.

Specifically, as shown in Figure 14, it is a schematic diagram of the service of a CM-IMS fixed-line caller who dials a common user in the CS domain, where A is the number of a common user in the CS domain; B is the primary number of the one-number user in the IMS domain ; B' is the associated number of the ONLY user, which may be an IMS domain or a CS domain. The specific process is as follows:

(1), the IMS domain one number number user UE_A dials the CS domain common user number B;

(2) The CSCF triggers the call to be processed on the AS according to the data signed by the calling number;

(3), AS does not modify the number display of the calling number according to the group user table GroupCallingFlag=1 and the calling and called numbers are not in the same group;

(4) The CSCF initiates a subsequent CS domain call process;

(5) The common user UE B in the CS domain rings, and the incoming call is displayed as the number of the calling UE_A.

As shown in Figure 15, it is a schematic diagram of a CM-IMS fixed-line calling One Number service user dialing an ordinary user in the IMS domain, where A is the number of an ordinary user in the CS domain; B is the primary number of the One Number in the IMS domain; B' is The number associated with the ONLY user may be an IMS domain or a CS domain. The specific process is as follows:

(1), the IMS domain one number number user UE_A dials the IMS domain common user number B;

(2) The CSCF triggers the call to be processed on the AS according to the data signed by the calling number;

(3), AS does not modify the number display of the calling number according to the group user table GroupCallingFlag=1 and the calling and called numbers are not in the same group;

(4), CSCF initiates the subsequent IMS domain call process;

(5) The common user UE_B in the IMS domain rings, and the incoming call is displayed as the calling number of UE_A.

To sum up, the embodiment of the present invention realizes the service function on the Centrex service side through the technical analysis of the service function realization process. This service is implemented by adding a special identification field to the group user table in the AS database to distinguish whether the ONLY function is triggered within the group or outside the group.

As shown in FIG. 16 , it is a schematic structural diagram of a one number service implementation system provided by Embodiment 2 of the present invention. The system includes a first judgment unit 100, a one number service trigger unit 200 and a normal call service trigger unit 300, specifically as follows:

The first judging unit 100 is used to judge whether the called/calling number at the opposite end is a number in the group when the main number of the ONLY user is used as the calling/called user, and if so, notify the ONLY service trigger unit 200, Otherwise, notify the normal call service trigger unit 300;

The ONLY service trigger unit 200 is used to trigger the service flow set by the ONLY user to connect to the call;

The normal call service triggering unit 300 is configured to trigger the normal call service flow to connect the call.

In particular, the system further includes a second judging unit 400 for judging whether the user is a ONLY user, and if so, notifying the first judging unit 100; otherwise, notifying the normal call service trigger unit 300 to trigger the normal call service flow to connect the call .

In particular, the system further includes a third judging unit 500, which is used to judge whether the ONLY user has set a different trigger call process for users inside and outside the group, and if so, notify the first judging unit 100; otherwise, notify the ONLY service triggering unit 200 Trigger the business process set by the ONLY user to connect the call.

In particular, the system further includes a group user table unit 600, which is used to set and maintain the status of the special handling flag GroupCallingFlag and the status of the special handling flag GroupCalledFlag.
