Abstract

PURPOSE: A method for processing a short message accompanied with a call signal is provided to enable an originator to transmit a short message accompanied with a call signal, and enable a receiver to generate a call signal, then to display the short message on a portable terminal, thereby transmitting a necessary notice by using the short message without frequently attempting a call. CONSTITUTION: An originator(10) generates a message which simultaneously transmits a short message with an originating call(S110), and transmits the generated message to an MSC(Mobile Switching Center)(20)(S120). The MSC(20) receiving the short message confirms whether a call signal is transmitted with the short message(S130). The MSC(20) confirms a transmission flag of the originating call of the short message, and decides whether an originating call transmission function is selected(S140). The MSC(20) transmits the short message with the originating call according to the decided results(S150), or selects a signal requested by the originator(10), and transmits the selected signal(S170).

Description

Method of processing short message with call signal {METHOD OF PROCESSING SHORT MESSAGE WITH CALL SIGNAL}

The present invention relates to a method for processing a short message with a call-signal.

Recently, as the use of the portable terminal has been generalized, various information delivery services using the portable terminal have been developed. The most representative of these information delivery services is a short message service (SMS) for delivering a short message using a mobile terminal and a caller ID (CID) display service for displaying the caller's information to the receiver.

Therefore, the mobile terminal users communicate using the short message service when the telephone call is not easy. In addition, if there is a missed call, the caller can be connected to the caller again using the caller ID service.

However, if the recipient is in a situation where he or she cannot answer the call and there is something to say to the recipient, the caller must continue to make calls or write a separate short message until the recipient receives the call.

The present invention has been made to solve the above shortcomings, and an object of the present invention is to send a short message accompanied by a call-signal and generate a call-signal at the receiving side. It is to provide a way to mark.

In order to achieve the above object, a short message processing method at a sender of a wireless communication network provided by the present invention includes a first step of adding a call-signal transmission flag to a short message transport packet to be transmitted to a receiver in response to a sender's selection command; And a second process of transmitting the short message to which the call-signal transmission flag is added.

The short message processing method in the exchange of a wireless communication network provided by the present invention includes a first process of receiving a short message from a calling terminal, a second process of checking whether a call-signal transmission is selected for the received short message, And a third step of simultaneously transmitting a call-signal and a short message to a receiving terminal based on a result of the second process confirming that the call-signal transmission has been selected for the received short message.

The short message processing method at the receiving side of the wireless communication network provided by the present invention includes a first process of receiving a short message accompanying a call signal and a second outputting call signal reception information in response to the received call signal. And a third process of displaying the received short message.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the same elements in the figures are represented by the same numerals wherever possible. In addition, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

FIG. 1 is a diagram illustrating a processing procedure of a calling party for processing a short message accompanying a call signal according to an embodiment of the present invention. Referring to FIG. 1, a process of an originating party for processing a short message with a call signal according to an embodiment of the present invention will be described below.

First, the sender selects the message accompanying call using the menu of the calling terminal (Fig. 1 (a)). Then, after selecting the 'Write a new sentence' menu of 'Write a letter' (FIGS. 1 (b) and 1 (c)), a text message to be delivered to a recipient is created (FIG. 1 (d)). Then enter the recipient's phone number and select OK (Fig. 1 (e)). Then, the text message and the call-signal created in the process (FIG. 1 (d)) are simultaneously transmitted to the telephone number of the receiver input in the process (FIG.

2 is a diagram illustrating a processing at a receiving side for processing a short message accompanied by a call signal according to an embodiment of the present invention. Referring to FIG. 2, when a receiving terminal receives a short message accompanied by a call signal, the receiving terminal displays the content of the short message and the caller information together with a guide message indicating that the call is received on the screen of the terminal (FIG. 2 (a)). When the called party answers the call, the receiving terminal connects the call between the called party and the caller, and if not (when the call is not received), the guide message notifying the missed incoming call, the received short message and the caller information are displayed on the screen. (FIG. 2 (b)).

Therefore, even if the receiver does not receive the caller's call, the receiver can know what the caller intended through the short message.

3 is an overall flowchart for processing a short message accompanying a call-signal according to an embodiment of the present invention. Referring to FIG. 3, a process for processing a call-signal short message according to an embodiment of the present invention is as follows. In FIG. 3, the call-signal generated at the originating side is distinguished from the call-signal received at the receiving side and received at the receiving side.

First, the calling party 10 generates a message for simultaneously transmitting an outgoing call and a short message (SM) (S110), and transmits it to the switching center 20 (S120). That is, in response to the sender's selection command, the call-signal transmission flag is added to the short message (SM) transport packet to be transmitted to the receiver, and the short message (SM) is transmitted to the switching center 20.

4 is an exemplary diagram of a short message structure accompanying a call-signal generated in step S110. Referring to FIG. 4, the short message includes a caller identification code 41 / an incoming call number 42 / an outgoing call transmission flag (Flag) 43 and a short message (SM) 44. An outgoing signal transmission flag (Flag) 43 is a field for determining whether to simultaneously transmit an outgoing signal when the sender transmits the corresponding short message (SM) 44. For example, when the foot signal transmission flag (Flag) 43 is '1', the short message (SM) 44 and the foot signal are simultaneously transmitted, and the foot signal transmission flag (Flag) 43 is '0'. In this case, only the short message (SM) 44 is transmitted without transmitting an outgoing signal. The caller identification code 41, the called phone number 42 and the short message (SM) 44 are also included in the existing short message structure, and detailed description of each field is omitted.

On the other hand, the switching center 20 receiving the short message SM from the calling party 10 checks whether the call-signal transmission is selected for the short message SM (S130). That is, the switching center 20 checks the outgoing signal transmission flag (Flag) 43 of the received short message SM and determines whether outgoing signal transmission is selected (S140). As a result, the short message SM and the outgoing signal are transmitted together (S150), or the short message SM or the outgoing signal is selected and transmitted (S170). For example, when the foot signal transmission flag (Flag) 43 is '1' as described in the description with reference to FIG. 4, the short message (SM) 44 and the foot signal are simultaneously transmitted and the foot signal transmission is performed. If the flag 43 is '0', only the short message (SM) 44 is transmitted without transmitting an outgoing signal. Also, if the short message SM is not included in the message received from the calling party 10, only the outgoing signal is transmitted.

The short message SM transmitted from the switching center 20 and the receiving side 30 having received the outgoing signal display the short message SM and the caller information CID and display the outgoing signal (for example, the hand signal) ( S160). At this time, the method of displaying the hand signal is the same as the conventional method of displaying the hand signal (for example, a ring tone or vibration). In addition, the receiving side 30 simultaneously displays the missed call guide message, the short message (SM) and the caller information (CID) when the corresponding receiving terminal fails the call for the hand signal.

5A and 5B are exemplary diagrams of a message structure for generating a short message with a call-signal in a Universal Mobile Telecommunication System (UMTS) terminal according to an embodiment of the present invention.

FIG. 5A illustrates a part of a transmission setup message format in a UMTS terminal. In this case, the partial recall alignment (Facility IE) is a part for setting information for an additional service, and the UMTS terminal can be configured to transmit a short message and an outgoing signal simultaneously by manipulating this part. . The transmission SETUP message format illustrated in FIG. 5A is well known to those skilled in the art, and thus a detailed description of the message format is omitted.

5B is a diagram illustrating an example of coding for the Facility Information Element (IE). Referring to FIG. 5B, it can be seen that additional service information can be stored from the third octet (octet 3) of the Facility IE and an Invoke ID tag has been added to determine whether to transmit a short message with a call signal. have. Since the coding for such Facility Information Elements (IE) is obvious to those skilled in the art, a detailed description of a coding method will be omitted.

Accordingly, as in the examples of FIGS. 5A and 5B, the UMTS terminal may simultaneously transmit a call-signal and a short message by changing a transmission SETUP message format. On the other hand, the receiving side may analyze whether the call-signal and the short message are transmitted at the same time by receiving and analyzing such a message.

In the above description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be defined by the described embodiments, but should be determined by the equivalent of claims and claims.

As described above, the present invention allows the sender to transmit a short message accompanied by a call signal, generate a call signal at the receiving end, and simultaneously display the short message on the portable terminal. Therefore, even if the call with the receiver can be delivered by using a short message that must be communicated to the receiver, there is an advantage that the caller does not know the situation of the receiver can try to call several times.
