Requesting information about another mobile terminal to switch to; Receiving information about another mobile terminal to be forwarded from the HLR according to a request for information about the other mobile terminal to be forwarded; And transmitting the short message to the MSC in which the other mobile terminal to be forwarded is located based on the information on the other mobile terminal to be forwarded provided from the HLR.

And when the destination type to be forwarded is set to e-mail, transmitting a short forwarding email address included in the short message and the destination terminal information to a web gateway interworking with the Internet. It is characterized by.

Hereinafter, a short message forwarding service method of a mobile communication network according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

3 is a road, a mobile terminal 10, an MSC 20, an SMSC 30, an HLR 40, and a web showing a configuration of a mobile communication network to which a short message forwarding service method according to the present invention is applied. The gateway 50 is provided.

In such a configuration, the MSC 20 receives a short message sent from the mobile terminal 10 through the base station and transmits the short message to the SMSC 30.

The SMSC 30 requests the destination terminal information from the HLR 40 based on the destination terminal number included in the short message transmitted from the MSC 20, and the incoming call received from the HLR 40 according to the request of the destination terminal information. After determining whether the short message forwarding service should be performed based on the terminal information, if the short message should be transmitted to the destination terminal, the short message should be transmitted to the MSC to which the destination terminal belongs and forwarded to another mobile terminal. If it is, the short message is transmitted to the MSC to which the terminal belongs, and if the call needs to be forwarded to the email, the short message is transmitted to the web gateway 50.

The HLR 40 is a database that stores all the permanent information of the mobile terminal required to connect an incoming call to the mobile terminal or provide other mobile communication services. The HLR 40 stores the terminal information at the request of the SMSC 30. Send to SMSC (30).

As described above, the mobile terminal information includes an electrical serial number, a user file, a current location (the MSC identifier in which the called mobile terminal is registered), and a flag indicating whether to use the short message forwarding service (Flag = Act (registered) / Inact (unregistered, Deregistration)), destination type information (Dest_type = 1 (other mobile phone) / 2 (email)) to be forwarded to, destination number to be forwarded to (Dest_number = phone number / email address), and the like.

The subscriber can register and deregister the short message forwarding service through the remote control service. When the subscriber registers the short message forwarding service, the registration information is stored in the HLR 40 supporting the short message forwarding service. do. Therefore, when the short message switching service is registered to be forwarded to another mobile phone according to the destination type to which call forwarding is desired, the registration information stored in the HLR 40 is 'Flag = Act, Dest_type = 1, Dest_number = 0191234567'. When the short message switching service is registered to be forwarded to an email address, the registration information stored in the HLR 40 is as follows: 'Flag = Act, Dest_type = 2, Dest_unmber=abcd@lge.com'. When the subscriber releases the registration of the short message forwarding service, the registration information stored in the HLR 40 is equal to 'Flag = Inact, Dest_type = 0, and Dest_number = Null'.

Meanwhile, the web gateway 50 transmits the short message received from the SMSC 30 to the corresponding email address through the Internet.

4 is a flowchart illustrating a short message call forwarding service method of a mobile communication network according to the present invention.

First, when the mobile terminal 10 sends a short message (S10), the short message sent by the mobile terminal 10 is received by the MSC 20 to which the mobile terminal 10 belongs (S12), the short message The received MSC 20 reads the routing table according to the message type, and transmits the received short message to the corresponding SMSC 30 (S14).

Thereafter, the SMSC 30 receiving the short message from the MSC 20 reads the routing table based on the called terminal number included in the short message, and requests the called terminal information from the HLR 40 (S16).

After receiving the terminal information requested from the SMSC 30 in step S16, the HLR 40 retrieves the terminal information for the terminal according to the request of the terminal information, and then transmits the retrieved terminal information to the SMSC 30. .

Subsequently, when the SMSC 30 receives the receiving terminal information from the HLR 40 according to the request of the terminating terminal information (S18), the SMSC 30 receives the short message received based on the receiving terminal information received from the HLR 40. It is determined whether to forward the call (S20).

In step S20, whether the short message is forwarded or not is determined based on the setting value of the short message forwarding service use flag included in the destination terminal information received from the HLR 40.

When the received short message is not forwarded, that is, when the short message forwarding service use flag is set to unregistered or deregistered, the called terminal information received from the HLR 40 is determined. The short message is transmitted to the MSC 20 in which the called terminal is located, and the MSC 20 receiving the short message from the SMSC 30 transmits the short message to the traffic channel after paging to the called terminal. (S22, S24).

On the other hand, when it is necessary to forward the received short message as a result of the determination of step S20, that is, when the short message forwarding service use flag is set to registration, the destination type to be forwarded is set to another mobile phone It is determined whether or not (S26).

As a result of the determination in step S26, when the destination type to be forwarded is set to another mobile phone, the call is sent to the HLR 40 based on the destination number (another mobile phone number to be forwarded) included in the destination terminal information. Request information on the terminal to switch (S28).

In step S28, the HLR 40, which has received the information about the terminal to be forwarded from the SMSC 30, searches for information about the terminal to be forwarded according to the information request for the terminal to be forwarded, and then retrieves the incoming call. The information on the terminal to be transmitted is sent to the SMSC 30.

Then, upon receiving the information on the terminal to be forwarded from the HLR 40 in response to the information request for the terminal to be forwarded in the SMSC (30) (S30), the SMSC 30 receives the call forwarding received from the HLR (40) The short message received based on the information on the terminal to be transmitted is sent to the MSC 20 where the terminal to be forwarded is located, the MSC 20 receiving the short message from the SMSC 30, the paging to the terminal After performing a short message to the traffic channel (S32, S34).

On the other hand, if the destination type to be forwarded is set to e-mail as a result of the determination in step S26, the destination number included in the short message received by the web gateway 50 interworking with the Internet and the destination terminal information (call forwarding). E-mail address) to be transmitted (S36).

In step S36, the web gateway 50 that has received the email address and the short message to be forwarded from the SMSC 30 transmits the short message to the email address to be forwarded through the Internet (S38).

The short message forwarding service method of the mobile communication network of the present invention is not limited to the above-described embodiment and can be variously modified and implemented within the range allowed by the technical idea of the present invention.

According to the short message forwarding service method of the mobile communication network of the present invention as described above, the short message is forwarded to the mobile terminal or the e-mail designated by the called party according to whether the short message forwarding service is used, thereby shortening voice as well as short text. Call forwarding services can also be provided for messages.

Accordingly, even if the called subscriber is lost or not currently carrying the terminal, it is possible to check the short message transmitted to his terminal through another mobile terminal or e-mail.
