The present invention relates to a rerouting service to a non-receiving wireless pager, which performs re-reception to a wireless pager as an additional function in addition to storing messages in the voice mailbox system when a call to the mobile phone is impossible.

Mobile phones, which have limited radio resources assigned and used simultaneously, have a lower incoming call success rate than wired phones and consume more power. Therefore, the mobile phones are powered off and only turned on when outgoing. Since there are many subscribers who use On, the incoming success rate is getting lower.

The mobile telephone exchange provides a voice mailbox service using a voice mailbox system as a way to overcome the low rate of incoming calls.

The voice mailbox service provides a function to store the voice of an outgoing subscriber by receiving the incoming signal to the voice mailbox system when the mobile subscriber cannot receive the call.

This voice mailbox function has the disadvantage of inconvenient to check whether there is a message received by the called party from time to time and the efficiency of the service when the caller disconnects the call without leaving a message to be delivered.

That is, the voice mailbox service, which stores the voice of the calling subscriber in the voice mailbox system when the incoming call is not received, has a problem of how to notify the mobile subscriber of the stored message.

On the other hand, there is a method of notifying that there is a message stored in the voice mailbox system by providing a unique sound when the mobile subscriber turns off the power and then turns on the power. There is no way to inform the calling subscriber that there is a stored message when the incoming call is not possible due to the delay and the situation other than the power on / off.

In addition, the call forwarding service provides a function to switch to a caller's designated forwarding number when the incoming call is unavailable. However, the call forwarding service and the voice mailbox service cannot be activated at the same time. The subscriber had a problem that only one of these two services could be provided at a time to improve the reception success rate.

In order to solve the above problems, the present invention provides a method for allowing a calling subscriber to enter a wireless call number and transferring control to a wireless call exchanger. The wireless call number of a mobile subscriber is stored in a database of a voice mailbox system. How to automatically transfer control to a wireless call exchange when there is a demand, and to store the mobile call subscriber's wireless call number in the database in the home location register in advance and to automatically transfer control to the wireless call exchange when requested. The purpose is to provide.

In order to achieve the above object, an embodiment of the present invention provides a rerouting service to a non-receiving wireless pager applied to a mobile telephone switch, and the calling subscriber requests a lock and receives a lock response message. A first step of requesting a translation to be notified of the number translation result, requesting routing information to receive routing information including a mobile subscriber routing number (MSRN), and analyzing the MSRN to call a called subscriber; A second step of conducting a normal call with the called party when a response from the called party is received as a result of the first step; And a third step of receiving a wireless pager number from the calling subscriber and transmitting it to the wireless call exchanger if the incoming call is impossible as a result of the first step.

2 is a flowchart of one embodiment according to the present invention.

If the calling subscriber tries to make a call to a mobile telephone subscriber with a re-call service function when the incoming call is unavailable, if the incoming call is not possible, the call is provided to the calling page by the exchange. When a call is requested and the caller wants to receive a call again, the caller receives the wireless call number from the calling subscriber and transfers the control to the wireless call exchanger. This process of the internal switch is described with reference to FIG.

The originating subscriber includes both a regular wired subscriber and a mobile telephone subscriber. Here, the service processing process is described for the origination of the mobile subscriber for ease of function description.

When the calling party presses the called number and the SEND button on the mobile phone, the called number is transferred to the silier mobile call processing block in a message inside the exchange called SETUP. ). The mobile call processing block inquires subscriber related information to the VLR (Visitor Location Register), and if it is determined that the subscriber can provide the service, the mobile call processing block notifies the calling subscriber of the call response message (202) and requests the digit translation to the number translation block (203). Upon receipt of the mobile call notification (204), routing information is requested to the VLR to determine the location of the called party (205).

The mobile call processing block, which has been informed of routing information including the Mobile Subscriber Roaming Number (MSRN) from the VLR (206), analyzes the informed MSRN and calls the called subscriber (207). Same as call processing.

The following description is a series of processes in the exchange that causes the pager to re-call when a normal call is not made between the calling party and the called party.

The mobile call processing block, which attempts to call the called party by the MSRN, makes a normal call with the called party when the answer is received from the called party (209), and the called party is powered-off, no answer, and no paging. If the call is not possible with one of (No Paging) (208), the call is forwarded to the voice mail system (VMS) (210).

When the incoming call processing to the voice mailbox system is completed, an announcement for function selection from the voice mailbox system is provided to the calling subscriber (211). When the calling subscriber who hears the announcement about the non-receipt and function selection presses the function selection number when he / she wants to be re-called by the wireless pager, it is assumed to be 3 and can be changed by the operator (212).

The voice mailbox system, which has received the wireless pager call selection from the calling subscriber, requests control transition to the mobile call processing block (213), and the received mobile call processing block disconnects the call line with the voice mailbox system (214) before sending it to the calling subscriber. An announcement broadcast to enter a pager number is provided (215). When the mobile call processing block receives the radio call number from the calling subscriber (216), it requests a digit translation with the number translation block (217). If the mobile call processing block is notified of the outgoing call notification and the occupied line occupancy in response (218), the radio call exchanger receives the radio call number. By sending the call digit (219), processing within the mobile exchange is complete and the wireless call exchange is then in control.

3 is a flowchart of another embodiment according to the present invention.

By inputting the pager number owned by the called party in the database of the voice mailbox system in advance, the mobile telephone switchboard can automatically call the prestored wireless call number when the called party cannot receive the call.

The originating subscriber includes both a regular wired subscriber and a mobile telephone subscriber. Here, the service processing process is described for the origination of the mobile subscriber for ease of function description.

When the calling party presses the called number and the SEND button on the mobile phone, the called number is transferred to the silier mobile call processing block in a message inside the exchange called SETUP, which is called a call request of the calling party (301). ). If the mobile call processing block determines the subscriber-related information to the VLR (Visitor Location Register), and determines that the subscriber can provide the service, the mobile call processing block notifies the calling subscriber of the call response message (302) and requests the digit translation to the number translation block (303). Upon receipt of the mobile call notification (304), routing information is requested to the VLR to determine the location of the called party (305).

The mobile call processing block, which has been informed of routing information including the Mobile Subscriber Roaming Number (MSRN) from the VLR (306), analyzes the informed MSRN and calls the called subscriber (307). Same as call processing.

The following description is a series of processes in the exchange that causes the pager to re-call when a normal call is not made between the calling party and the called party.

The mobile call processing block, which attempts to make a call to the called party by the MSRN, makes a normal call with the called party when the answer is received from the called party (309), and the called party is powered off, no answer, and no paging. If the incoming call is not possible due to one of (No Paging) (308), the call is forwarded to the voice mail subsystem (VMS) (310).

When the processing of the incoming call to the voice mail system is completed, the voice mail system provides the announcement to the calling subscriber that the call is impossible and the function selection (311). When the calling subscriber selects the wireless pager call (312), the voice mailbox system stores the stored wireless. The call number is retrieved (313) and the wireless pager number owned by the called party is transferred to the mobile call processing block by the control transition request message. The wireless call number of the voice mailbox system is transmitted when the subscriber requests the service function. It is stored by the operator.

The mobile call processing block notified of the radio call number disconnects the call path with the voice mailbox system and requests translation of the radio call number to the number translation block (316). When the mobile call processing block is informed of outgoing call notification and outgoing line occupation as a result of the number translation (317), it transmits a radio call digit to the radio call exchanger via the occupied trunk (318). This completes the processing of the mobile telephone exchange for re-call to the wireless pager, and thereafter performs the unique radio call call processing function in the wireless page switch.
