Description

Personal Number Service Second Call Forwarding Method

The present invention relates to a personal number service, and more particularly, to a method for connecting a secondary number of a personal number service.

Personal number service is an intelligent network service using a public telecommunication network. It uses a personal number rather than a general line number (PSTN network number) to allow users to receive incoming calls regardless of the type and location of the communication terminal. to be

The service subscriber registers his mobile location in the network by using his / her unique number assigned to him, that is, his / her personal number and his / her password. Mobility can be guaranteed.

Current public switched telephone networks (PSTNs) use physically fixed line numbers as a means of identifying service users. Therefore, when moving the location it is possible to communicate only if the called party has changed the called party.

However, the personal number service uses a logical personal number irrelevant to the physical line as an identification means of the service subscriber. Therefore, if the caller attempts to dial the personal number of the service subscriber and the call is made, the personal number is translated by the network and the incoming call is received. Therefore, regardless of the location change or address transfer of the service subscriber, the caller uses the personal number to connect with the service subscriber. It allows you to always communicate. In addition, in the mobile communication network as well as a wired network, such as a public telephone network, by registering the location with a mobile phone or a wireless pager can receive a call from the desired terminal.

However, there is a problem that a service may not be completed due to a failure of the first incoming call such as no answer or a call when the telephone user in the public network attempts to connect to the personal number service subscriber.

In order to solve the above problems, the present invention provides a secondary service for reducing the cause of service incompleteness due to a first incoming call failure (no answer, during a call) when a telephone user in a public network attempts to make an incoming call to a personal number service subscriber. It is an object of the present invention to provide a personal number service secondary incoming connection method having an incoming function and enabling a voice message service within the personal number service to improve convenience.

In order to achieve the above object, the present invention provides a personal number service secondary incoming connection method, comprising: a caller receiving a call request requesting a call to a personal number service subscriber and requesting a personal number service to an intelligent network service exchange means; Stage 1; A second step of receiving, by the intelligent network service exchange means which has received the personal number, the calling party requesting and receiving the calling number and transmitting the calling information to the intelligent network service control means; A third step of transmitting personal number information of an outgoing call capable of providing a service to the intelligent network service switching means after receiving the outgoing information; A fourth step of, after receiving the personal number information, connecting the calling party with a first destination number and charging information for the first incoming call to the calling party; Attempts to connect to the first called number, and if the first called party is in a normal state, connects the call between the caller and the first called party and ends the service, and the first called party is abnormal (predetermined). Transmitting a recovery message for requesting recovery of a connection state to the first called party when a non-responsive state or a busy time is over); And a sixth step of attempting to connect a call to a second called number, ending the service after connecting the call between the second called party and the caller corresponding to the second called number.

If the subscriber does not answer the phone with the registered called number, the user can leave the desired message by registering the location in the voice mailbox, an intelligent peripheral used for intelligent network service, and the subscriber can also search for these stored user messages. Can be. The voicemail box also has the function of message retrieval and automatic call generation, so if there is a message to be delivered to the service subscriber every time, the subscriber who has the message gets the current location information of the subscriber from the intelligent network service controller and automatically calls the call. Delivers the message that is generated and stored.

If the registered called number is busy or unanswered, it may be registered by re-designating the second called number that is desired to be called in case the incoming call is difficult. In this case, when the called party is unanswered and connects to the secondary called number, the time required for retrying the routing is similar or slightly shortened by referring to the non-response waiting timer of the telephone message transfer service that is commercially available from KT.

In the secondary numbering method of the personal number service according to the present invention, a call for requesting a connection with a personal number service subscriber is generated from an arbitrary sender in the public network and inputted to an intelligent network service switching point (SSP) through an originating exchange. Incoming information is requested by an intelligent network service controller (SCP) 6 interworking with the intelligent network service exchanger and the No. 7 signaling network. After receiving the incoming information of the service subscriber from the intelligent network service controller, the intelligent network service exchanger attempts routing for incoming connection.In this case, the incoming terminal includes the mobile network and the international area, and if the incoming connection is difficult, the subscriber registers. It can also be called by an intelligent peripheral. In addition, if the first incoming call fails during a call or no answer, the incoming call from the SCP is attempted to connect to the second incoming call.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a structural diagram of a personal number service secondary incoming connection system to which the present invention is applied.

The personal number service incoming connection system includes the general subscriber (1), the calling terminal switch (2) to which the general telephone subscriber (1) belongs, the intelligent network service switch (3), the intelligent network service controller (6), the destination terminal switch (7), A called subscriber 8, an intelligent peripheral 13, and a mobile network switch 9.

After recognizing the service call generated from the calling party station (1) and the calling terminal exchange (2) to which the general calling party (1) belongs, collect password and permission number as necessary, and receive incoming information on the entered personal number. Service control point (SCP) (6) and the intelligent network service switching (SSP) (3) that performs relay routing processing according to the response destination information and the personal number received from the SSP Search the service subscriber database you have. After that, it can be configured as an intelligent network service controller that performs the function of delivering the announcement and billing, incoming information to the SSP to the current user.

SSP's ISUP message is an intelligent peripheral device (13) to enable voice message delivery from service users even when the personal number service subscriber does not have a communication terminal capable of receiving a call at the current location or a call is unavailable. It interlocks through the processing unit 12.

The calling station switching center 2 collects called number information of the personal number service call from the service user 1 and relays it to the SSP 3. The intelligent network service exchanger (3) recognizes that a call input from any end station is a personal number service call through a relay line matching section (4), which is in charge of R2 signal processing and No.7 ISUP message processing, and recognizes that the call is a private number service call. 3) Collect the calling number from the calling station 1 to generate the billing data within. If necessary, the personal number service subscriber can change his or her profile, that is, register the phone number where he is currently located, register the secondary called number, use the voicemail box, and enter the password and permission number Additional information may be collected as a result of changes).

The SSP (3) receives the incoming information to the intelligent network service controller (6) having a service profile subscriber database to obtain the information for the actual incoming to the personal number service subscriber with such collected personal number, calling number, calling grade, etc. The intelligent network service exchanger (3) and the intelligent network service controller (6), which have a query message requesting the interworking message, interoperate with the No.7 signaling network. Therefore, the personal number information collected from the calling station is configured in the No.7 signal format. Question and Answer function with SCP (6) The relevant function is handled through the operation unit and the application service element (5) that exists independently for each intelligent network service. The intelligent network service controller 6 searches the database for the subscriber by using the personal number information input from the SSP 3, and then the first and second telephone numbers to be actually received, the type of announcement that the service user will listen to, and billing. Incoming information such as a form is provided to the SSP 3. As a result, all data necessary for the first level personal number service is transmitted and received, and the SSP 3 starts relay routing for the actual incoming with the incoming information received from the SCP 6. When a call requesting an incoming call is inputted to the destination terminal switching center 7 and the incoming call state is busy, a service connection of the calling party is made. When the personal number service subscriber has registered his current location telephone number as a mobile communication terminal, the SSP may be relayed to the mobile switching center 9 through the E1 / T1 relay line and may be received by the mobile phone or a wireless pager. At this time, if the incoming subscriber state is not available (no answer, busy), the SSP (3) detects this and attempts to reroute for the second incoming using the second routing information received from SCP (6). . If busy, R2 signal or No. In the case of the 7 signal, the SSP 3 is notified by the ISUP release message, and the detection of the non-response is regarded as the non-response when there is no response until the end of this timer by driving a specific timer in the SSP. However, in the case where the incoming call is impossible even in the second incoming call, incomplete processing is performed. In the case of the second non-response, the final incoming call is normally performed by driving a normal non-response wait timer (for example, 2-3 minutes).

In the situation where the service subscriber does not have an incoming terminal or a call is impossible, interworking is performed through the ISUP message processing unit 12 of the SSP 3 so that the service user can store a voice message to the intelligent peripheral device 13. Intelligent Peripheral Peripheral Device (13) allows the subscriber to use the mailbox, and the subscriber receives the personal number and the calling number to enable the service subscriber to search for the messages stored in his or her mailbox. It is delivered through (IAM: Initial Address Message). A personal number for selecting a mailbox is displayed in the first called number field of the first address message, and the routing number and calling number sent to the intelligent peripheral device are sent in one message at a time, so that the service can be quickly connected.

2 is a flowchart illustrating an embodiment of a personal number service secondary incoming connection method according to the present invention.

The second number of the personal number service is that the service user belonging to any originating station picks up the handset to send to the personal number service subscriber (21) and then checks the dial tone transmitted from the originating station (22), and the service identification number (SAC: This is accomplished by entering 23 a Service Access Code (PTN) and a Private Telephone Number (PTN).

The originating station routes this call to the SSP when it receives a parameter. When the SSP detects that the call is a request for personal number service, it first requests the calling number from the calling station (25) and the calling station informs the calling number (26). The SSP sends a message (27) containing the collected information (SAC, personal number, calling number, calling grade, etc.) to the SCP for further processing of the call.

After receiving a message, SCP requests the permission number (28) when the call cannot be provided for any other reason, such as if the call is restricted or unregistered personal number (28), and the SSP sends the announcement to the user in each case (30). If the individual number subscriber has activated the selective call permitting function, the SSP can send the call status and billing information to the calling party. The license numbers for the digits are collected (31, 32). If the permission number is not needed, steps 28 to 32 are omitted.

As a result of the command provided, SCP transmits (33) the primary and secondary actual called number of the individual number, billing information, type of announcement, and automatic call control information during congestion. Is transmitted 34. When the SSP receives a request for call guidance from SCP, the SSP informs the user of the billing information of the corresponding call through the announcement and allows the user to select whether to continue the call (35). As the destination area extends not only to the mobile network but also to the international area, the user must be informed about the charges to be charged and the user must select whether or not to make a call. If the service user wants to continue the call, he presses '#' and if he does not want to hang up the handset, the call ends 36 with the user's relinquishment.

When the service user wants to continue the call, the SSP connects the call to the called party by using the first routing information 37, and the destination exchange sends the charging signal 38 to the SSP. The called party notifies the call that the call has occurred by transmitting 39 a call signal, and notifies the service user of the current call by transmitting 40 a call tone. If the called party is busy, the service call is connected at the primary by sending a response signal from the called exchange. Otherwise, the timer is driven (41), and if the unanswered state lasts for a certain time or if the called party is busy, the incoming call is abnormal. And the SSP sends a recovery message to the called party to recover the called party's connection status to the primary called (42).

If the first incoming call fails, the SSP announces to the service user that the call is directed to the second called number (43), and informs the user of the billing information corresponding to the second incoming call through the announcement and selects whether to continue the call. (44) We can do it. The service user ends the call by pressing '#' if he / she wants to continue the call, or by hanging up the handset if not desired. When the service user wants to continue the call, the SSP attempts a routing 46 for the call connection to the called party once again using the second incoming information. If the routing is successful, the called party exchange reports the status and billing information of the called party to the SSP (47), and if the called party is busy, sends a call signal to the called party (48), and the called user is called. The alert connects the call echo (49). When the last called party responds (50), the response signal is transmitted to the calling station through the SSP (51) to make a call 53 between the user and the called party and the service is terminated. If the called party is abnormal even at the second incoming call, the service is terminated in an incomplete state.

When the caller calls the personal number service subscriber while the service is running (61), the originating exchange routes the service call to the SSP (62). The SSP recognizes the personal number service call and constructs a No.7 signaling message to be sent to SCP by collecting the calling number and calling grade from the calling exchange (63). No. configured through intelligent network application service element and question-and-answer function application unit. 7 Send the message in the form of command provision (64). If the subscriber to the personal number service has registered the call permission function, the SSP connects the announcement requesting the caller to input the permission number, and if the permission number is authenticated, service follow-up processing is performed. ). SCP searches the database of the current personal number service subscriber and constructs the subscriber's incoming information into No.7 signaling message (66) and sends it to the SSP in the form of a success response to command provision (67). After receiving the success response, the SSP analyzes the incoming information and connects the called area guide indicating the charging contents and the call availability input announcement (68).

If the caller wants a call, the first attempt is made using the incoming information (70). Otherwise, the service is terminated. If the first routing is successful and the connection is made to the destination exchange and the called party is in a normal state during the call, the called party exchange sends a call signal to both the calling party and the called party. The response wait timer is driven (72). If the called party answers before the timer expires, the calling party is connected (74) to make a call and the service is terminated.

If the called party does not answer or cannot connect to the busy state until the timer expires, the SSP recognizes this and checks whether the second incoming information is registered (61). If there is no registered second incoming information, the service is terminated, but if present, it connects the destination area guide for the second incoming call and the call input input announcement once again (75). If you do not want the call, the service is terminated, otherwise, try the second routing (77) to check if the incoming state is normal (78), and if it is abnormal again, the service is incomplete and even during normal If the called party responds while waiting for the subscriber to answer without running a specific response waiting timer for the non-response state check, the call is completed between the called party and the called party (79).

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

As described above, the present invention, unlike general telephone users, minimizes the incompleteness of the service caused by causes such as reception failure due to the use or absence of the telephone and increases the quality of service by increasing the opportunity for call connection between the caller and the called party. There is an effect that can be improved. In addition, there is an effect that can greatly improve the efficiency of the use of resources in the switching system by reducing unnecessary resources in the switching system wasted by the retry of the same call due to the reception failure.
