How to provide messenger service using wireless internet {Method for providing messenger service using wireless internet}

The present invention relates to a method for providing a messenger service using the wireless Internet. In particular, the present invention can provide a messenger service even without always accessing the wireless internet, and when the connection is disconnected due to an incomplete wireless internet network, The present invention relates to a messenger service providing method using a wireless Internet with a function of resending a message.

Recently, as the spread of the Internet expands, the number of users using the mail service is exploding, and the spread of mobile communication is also rapidly increasing, and the research of new types of services by the combination of the mail service and the mobile communication technology is actively studied. It's going on.

One example of such research is a wired site for short message service (SMS) transmission. These Internet sites have a function of transmitting an SMS message to a mobile communication terminal through the Internet after registering a user through a home page.

The SMS stores and transmits the data packet in the Short Message Service Center (SMSC). In other words, by taking a store-and-forward scheme, the SMSC has a burden on data packet transmission on the network.

The operation of the SMS is a method in which all messages are collected in the SMSC when the sending mobile terminal sends a message. The SMSC then collects and stores all messages and then sends the message to the subscriber of the receiving number.

If the receiver's mobile terminal is in a ready state, a message is sent immediately. If the terminal is out of the service area, the terminal is depleted, the terminal is turned off, or the terminal has insufficient storage capacity. It is a structure that attempts to transmit a transmission message to a portable terminal of a receiver periodically.

However, these SMS systems have the following problems.

First, the user can easily send a message to the user who wants it, but the continuity of the conversation is reduced by supporting only one-way text transmission.

Second, there is a great risk of losing sentences in the middle due to incomplete wireless Internet network.

Third, because it supports only one-way message delivery, it is impossible to know whether a message has arrived.

Fourth, it only supports the use of characters defined as extended ASCII, which does not satisfy the various needs of users.

Another method is the Instant Messaging Service, which is a wireless Internet connection. This method allows a user to use an instant message after accessing the Internet through a mobile communication terminal capable of wireless Internet access, which is often referred to as a wireless Internet chat room or a wireless Internet messenger service.

However, this method also has the following problems.

First, although it is possible to talk with various parties, it is necessary to always be connected to the wireless Internet, which entails an undesired increase in cost, and it is difficult for a network operator to effectively use a wireless network.

Second, the response to the invitation of other users during use is slow.

Third, the connection is easy to be disconnected due to an incomplete wireless internet network, and at this time, there is inconvenience in using a reconnection.

Fourth, by supporting the use of extended ASCII-based sentences and other special characters only, it does not meet the various needs of users.

The present invention has been made to solve the above problems, it is possible to provide a messenger service even if not always connected to the wireless Internet, and if the connection is disconnected due to the incomplete wireless Internet network to reconnect and resend the message The present invention relates to a method for providing a messenger service using the wireless Internet to which a function is added.

In step S305, when the caller client connects to the messenger server, in step S310, a message is requested to transmit a friend list to the messenger server.

Subsequently, in step S315, when the caller client receives the friend list update information from the messenger server, in step S320, the user selects a talker and transmits the information about the selected talker to the messenger server.

If the talker sent to the messenger server does not accept the conversation, in step S325 it is informed that the talk is in an unavailable state, and the flow returns to step S320.

In addition, when the conversation message transmitted to the messenger server accepts the conversation, in step S330, the message informs that the connection with the other party is made, and then the conversation step is entered.

On the other hand, the process occurring on the receiver client side is as follows.

First, in step S340, it is determined whether the information of the recipient client has been modified, and if corrected, by sending the modified information to the messenger server, the user information database is continuously updated. This process continues.

If an invitation message is input from the messenger server in step S345, it is determined in step S350 whether to accept the conversation with the invitation message.

As a result of the determination in step S350, when accepting the conversation, in step S355 it is determined whether or not a messenger program exists in the terminal on the receiver client side.

As a result of the determination in step S355, if it does not exist, in step S360, after downloading and installing a messenger program from the messenger server, in step S365, a messenger program is connected to the messenger server, and the following conversation is described later. Enter the stage. On the other hand, if the messenger program exists as a result of the determination in step S355, the flow proceeds directly to the step S365.

On the other hand, the process that occurs on the messenger server side is as follows.

First, in step S370, when the changed receiver client information is received from the receiver client, the modified client client information is corrected and updated in the user information database. This process occurs continuously.

In step S375, upon receiving the server connection request message from the sender client, a channel is established to connect with the caller client.

In addition, in step S380, the friend list request message is received from the caller client to determine whether new information exists, and if it is new information, the caller client is notified to update the friend list.

In step S385, when the selected talker information is input from the sender client, an invitation message is transmitted to the receiver client.

In addition, in step S390, when receiving a message rejecting the acceptance of the conversation from the receiver client, it is notified to the sender client to be notified of the conversation.

In step S395, when a connection request message is received from the receiver client, an access channel is established, and the caller client is informed to inform the caller that the connection is established.
