The present invention relates to simultaneous mobile chat with multiple parties using a mobile terminal, and more particularly, to a mobile terminal and a multi-chat method for increasing the number of chat rooms that can be connected simultaneously using a limited memory area of the mobile terminal.

The mobile communication system is a system that provides a mobile communication service as a basic service, in which a mobile terminal, which is subscribed and registered, freely moves in a service area and communicates by voice signal immediately by wirelessly accessing a designated party at any time and anywhere.

In general, when a mobile terminal communicates with a voice signal, it occupies a radio channel exclusively until communication is completed.

The digital communication of the mobile communication system enables the data communication of the mobile terminal, thereby enabling non-real-time text message communication.

Text message communication by data communication of a mobile terminal performs packet data communication by control and monitoring of a mobile communication system.

Text message communication is one of the additional services with high utilization and preference as it increases the operational efficiency of the mobile communication system and at the same time makes the communication cost much lower.

In addition, in the development of non-real-time text message communication, mobile phone (MOBILE CHATTING) or messenger (MESSENGER) additional service, which is a real-time text message communication using a mobile terminal, has been developed to further increase the utilization and added value of the mobile communication system. All.

Mobile chat (hereinafter referred to as chat) value-added services are increasing in preference and utilization due to advantages such as real-time connection and message communication with several people.

1 is a configuration diagram of a chat function of a general mobile communication system, and FIG. 2 is a flowchart illustrating a chat operation method of a general mobile communication system.

Referring to FIGS. 1 and 2, a general mobile communication system and a chat operation method thereof will be described. The mobile terminal 100 moves freely in a service area 130 formed by a base station 120 of a mobile access network 110. Chat with the mobile terminal 105 of the other party.

The mobile terminal 100 may perform a multi-chat in which a chat is performed simultaneously with another mobile terminal, in addition to the mobile terminal in which the chat is in progress.

In addition, the mobile switching center 140 constituting the mobile access network 110 may be connected to other communication systems through the public network (160).

In order to conduct a chat with a mobile terminal, a chat room must be opened, and in order to have a multi-chat, a chat room must be opened in multiple ways, and each chat room has message data and logs transmitted and received as the chat proceeds. Information should be recorded and maintained.

That is, each chat room should be allocated a memory area of a certain size.

The mobile switching center 140 constituting the mobile access network 110 controls the chat server system 150 to open multiple chat rooms, assigning counterparts to each chat room when there are multiple chat requests from the mobile terminal. Set the chat path for sending messages to multiple simultaneous.

In other words, the mobile switching center 140 checks whether the mobile terminal 100 or 105 requests to chat with the designated counterpart mobile terminal 100 or 105 (S100).

When it is confirmed that there is a chat request from the mobile terminal, the mobile switching center 140 controls the chat server system 150 to open a chat room (S110).

Since the chat server system 150 secures a large memory area for opening a chat room, the chat server system 150 immediately establishes a multiplicity of chat rooms by a desired number at the request of the chat room opening request of the mobile switching center 140.

The mobile switching center 140 establishes a chat room at the same time, controls the chat server system 150, checks the location information of the designated counterpart mobile terminal, and simultaneously sets multiple chat paths (S120).

The mobile switching center 140, when it is confirmed that there is a request for opening a chat room from the mobile terminal (S130), returns to the opening process (S110), and controls the chat server system 150, thus additionally opening a chat room and adding the same. Since the process of checking the location of the counterpart is repeated and additionally setting the chat path (S120), the chat room is opened in multiple ways and the path is set in multiple ways.

The mobile terminal performs simultaneous multi-chat with each mobile terminal of the multi-opened chat room by the control and management of the chat path and the chat server system set by the mobile switching center 140 (S140).

Since the chat server system 150 records and manages the chat messages and log information which are in progress with the counterpart mobile terminal in each chat room, the chat server system 150 continuously checks the location information of each mobile terminal and provides the mobile switching center 140 to the mobile terminal 140. Even if the mobile terminal is in a mobile state, the multiple established chat paths are maintained.

As described above, the conventional method has the advantage of multi-chatting without limit on the number of counterparts, but there is a problem in that a fee must be paid because a chat server system is used.

Therefore, there is a need to develop a technology for multi-chat by the mobile terminal itself without using a server system.

3 is a flow chart of a multi-chat method of a mobile terminal according to the prior art.

Referring to FIG. 3, when a user wants to chat with a counterpart designated by the mobile terminal (S200), a predetermined area is allocated and allocated for setting a chat room among heap memory, which is an operating memory of the mobile terminal (S210).

Using the chat room set as the heap memory allocation of the mobile terminal, a mobile chat is performed with the specified counterpart (S220).

The chat can be proceeded by concurrently connecting with a plurality of counterparts, confirming whether to add the counterpart (S230), and when adding a counterpart, whether there is a free area to be allocated and allocated in the heap memory to set up a chat room. Check (S240).

If the free space that can be allocated for the chat room setting remains in the heap memory, the process returns to step S210 to further allocate the heap memory for the chat room, thereby adding a chat counterpart.

As described above, a multi-chat with the designated party is performed through the multi-configured chat room (S250).

However, when the free area of the heap memory is small, it is impossible to add a chat room.

In general, the heap memory, which is an operational memory area, is a main memory area in which the control unit (CPU) temporarily stores data for executing an operation program, and the like, and when the spare area that can be operated is small, the program execution speed decreases and is operated. If the area is insufficient, a system down occurs.

Since portable terminals are important in mobility and portability, and are generally light and small in size, they cannot be expanded indefinitely in main memory or heap memory capacity.

This conventional technology improves the problem of using a server, but since the capacity of the main memory or the heap memory built in the mobile terminal is limited, there is a problem in that the number of the counterparts of the multi-chat that can simultaneously carry out the mobile chat is extremely limited.

Therefore, there is a need to develop a technology that is not limited to the number of multiple chat counterparts using a mobile terminal.

It is an object of the present invention to provide a mobile terminal and a multi-chat method which provide a mobile terminal and a multi-chat operation method that is not limited to the number of multi-chat counterparts using the limited memory capacity of the mobile terminal.

The present invention has been made in order to achieve the above object, the control unit for allocating a predetermined area of the heap memory unit to the chat room, the control unit to manage the reallocated back to the new chat room by backing up the data of the old chat room in the multiple chat room; A heap memory unit which is used as an operation area under control of a controller and allocates a plurality of predetermined areas to a chat room; A backup memory unit for backing up and storing chat room data of the heap memory unit under control of the controller; A chat unit which modulates and demodulates the multiple chat data transmitted and received by the control unit; A configuration including a wireless unit for wirelessly transmitting and receiving a multi-chat signal under the control of the controller is presented.

In addition, the present invention devised to achieve the above object, in the case of multi-chat by a mobile terminal, analyzes the available size of the heap memory unit, determines the number that can be distributed to the chat room, and assigning the chat room by the chat partner input order Process; When the chat proceeds through the assigned chat room and the chat counterpart is added, it is confirmed whether the number of the determined chat room is exceeded, and if not, a confirmation process for returning to the allocation process; When it is determined that the chat room is exceeded, sorting the chat rooms in order of access time, backing up the information of the old chat room, and assigning the chat room as a new chat room; If you want to chat through the backup chat room is presented a configuration that includes the process of feedback to the above process.

Hereinafter, with reference to the accompanying drawings, a mobile terminal and a multi-chat method according to the present invention.

4 is a functional configuration diagram of a mobile terminal according to the present invention, and FIG. 5 is a flowchart of a multi-chat method of the mobile terminal according to the present invention.

Referring to FIG. 4, according to an embodiment of the present invention, a mobile terminal will be described. A controller 200 for managing multiple chat room settings and data backups, a heap memory unit 210 for multi-allocating a chat room, A backup memory unit 220 for recording the backup data, a chat unit 230 for modulating and demodulating the multi-chat data, a wireless unit 240 for wirelessly transmitting and receiving a multi-chat signal, and an input unit 250 for inputting the multi-chat data. ), An output unit 260 for outputting multiple chat data, and a program unit 270 for recording operation and application programs.

Referring to Figure 4, the mobile terminal according to the present invention will be described in detail.

In the mobile communication system, the mobile terminal communicates wirelessly while the mobile terminal freely moves within the service area formed by the base station. The service area formed by the base station is limited in size or radius.

The radius of the service area formed by one base station is, for example, from several tens of meters to several kilometers. In general, the radius of the service area is small in the city center, and the radius in the outskirts of the city and the countryside is large.

Therefore, call charges of mobile communication systems are relatively expensive due to features such as continuous installation, control, and maintenance of a plurality of base stations.

The communication is connected to the other party to transmit and receive a voice signal in real time, and has a characteristic of occupying one of a limited channel in real time.

In addition, there is a characteristic that a large amount of communication occurs during the day, commute time, meal time.

In other words, the communication system may be concentrated in a certain time period, and the call volume may be low or very low in the remaining time periods. Therefore, increasing the operation rate is an important goal for a system operator or a business operator.

One of the ways to increase the operation rate is an additional service, for example, a message service, TV, VOD, online games, chat services and the like.

In the case of the message service, a non-real-time connection with the other party, a text message and a multimedia message are communicated, and a real-time connection is a chat or messenger service, and a mobile terminal is used. Also called mobile chat.

The chat uses a multimedia message including a video or a text in a text, and is a data communication method, and transmits and receives data in a high-speed packet, thereby simultaneously performing multi-data communication.

Therefore, in the case of chat, which is a real-time communication, there are multiple chats.

In the case of chatting, especially when using text, log information such as text messages sent and received and the time of connection are constantly recorded in the allocated memory, and if necessary, the contents of previously transmitted messages are checked again or separately. The method of recording and storing is adopted.

Therefore, for chat, it is necessary to open a chat room that allocates a certain amount of memory.

In particular, in the case of multiple chats, since multiple chat rooms must be opened, a large number of memory areas must be allocated.

The chat progress in the mobile terminal is managed in real time by the control unit, and allocates a working memory or heap memory, which is a main memory, to the chat room.

Since the portable terminal is a device that communicates while moving, the resource (RESOURCE) is integrally provided in order to meet the conditions such as small size, small size, and light weight.

It is a technique of the present invention to overcome the problem of limited memory resources among the limited resources as described above, and to provide a chat room of a desired number.

In the mobile terminal configuration of the present invention, when the operating power is applied, the control unit 200 reads the OPERATING program, the APPLICATION program and the corresponding data from the program unit 270 and enters an operation standby state.

Such applications include programs for multiple chats.

In this way, the control unit 200 which is in the standby state for operation analyzes the control command applied from the input unit 250 while monitoring each function unit, and when it is confirmed that a chat is performed, the control unit 200 of the heap memory unit 210 which is an operating memory area is checked. The size available is analyzed and a number N that can be distributed to a predetermined size for the chat room is determined.

That is, the controller 200 analyzes the available size of the heap memory unit 20 to confirm that the memory can be distributed to the N chat rooms, and determines that up to N chat rooms can be opened.

If the control unit 200 confirms that the command to request a chat by designating the other party from the input unit 250 is authorized, the control unit 200 assigns the chat rooms to the heap memory unit 210 in a predetermined order to proceed with the chat with the designated party. do.

The chat message data and log data created and input for transmission to the other party are recorded in the chat room allocated to the heap memory unit 210 under the control of the controller 200, and applied to the output unit 260 for display. Therefore, it is confirmed by the user.

If the controller 200 determines that the command for requesting a chat message to be transmitted to the counterpart is received from the input unit 250, the controller 200 applies the chat unit 230 to the chat unit 230 under the control of the controller 200.

The chat unit 230 encrypts or modulates the chat message data to be transmitted to the controller 200, and the controller 200 transmits the encrypted chat message to the wireless unit 240. Since it is applied, it is wirelessly transmitted by the wireless unit 240.

The chat message data wirelessly transmitted from the wireless unit 240 is received at the base station 120 of the mobile access network 110 and transmitted to the designated counterpart mobile terminal through the path set by the mobile switching center 140.

In addition, since the chat message data received from the chat counterpart via the wireless unit 240 is applied to the chat unit 230 by the control unit 20, the chat message data is decoded or demodulated.

The controller 200 records the chat message data transmitted from the counterpart in the corresponding chat room of the heap memory unit 210 and applies the displayed message to the output unit 260 so as to be confirmed by the user.

At this time, for a multi-chat, if a command to simultaneously chat by specifying a different party from the input unit 250 is applied, the control unit 200, according to the following order from the N chat rooms set in the heap memory unit 210 Allocate a chat room.

However, if it is confirmed that all N chat rooms set by the controller 200 are in use, the chat rooms are sequentially sorted by the chat connection time, and the chat room having the oldest connection time is selected.

The controller 200 backs up all data of the chat room selected as the oldest chat connection time in the backup memory unit 220 and simultaneously erases the data, and assigns it to the chat room of the other party requesting a new chat. do.

The backup memory unit 220 may selectively store the data to be backed up in a compressed state.

If the counterpart to continue to chat, the process of backing up the data content of the chat room, the oldest connection time among the N chat rooms in the backup memory unit is repeated, there is no limit to the number of counterparts to multi-chat.

At this time, if the chat data is to be resumed with the other party backed up, as in the case of allocating a new chat room, among the N chat rooms currently in operation, the data of the chat room with the oldest connection time is the backup memory unit 20 Backs up in a compressed state, deletes its contents, and reassigns it to the chat room.

In this reallocated chat room, since the data that was previously backed up in the compressed state is decompressed and recorded, the output unit displays a message and log information that has been previously performed, and the chat can continue.

Therefore, even in a mobile terminal with limited memory resources, there is an advantage that the number of multiple chat counterparts can be increased without limiting the size of the memory.

Referring to Figure 5, according to the present invention, when explaining a chat room operating method of a mobile terminal, the process of analyzing the available size of the heap memory and determining the chat room number N to be distributed; When adding a chat room, checking if there are more than N chat rooms; When the number of N chat rooms is exceeded, the configuration includes a process of backing up the data of the oldest chat room, erasing and allocating the chat room to be added.

When the chat room operation method by the mobile terminal is described in more detail, the control unit 200 analyzes the control command applied from the input unit 250, and when it is confirmed that the multi-chat (S300), the heap memory unit which is the operating memory In 210, the size of the available capacity available to occupy is detected and analyzed (S310).

The mobile terminal is provided with various types or uses of memory, and the memory occupied and used by the controller 200 for basic functions and selected application programs is called a heap memory unit 210, and a backup (BACK-UP) memory is used. , A cache (CASH) memory, and the like, and the capacity or size of the heap memory unit 210 is constantly limited by the characteristics of the portable terminal to be made compact.

The available capacity or size analyzed from the heap memory unit 210 of the portable terminal is divided by the memory size required to open the chat room, and the number N of the chat room capable of setting an integer of the divided value is determined (S320).

The mobile terminal allocates a designated party to the chat room in order in the determined range of the chat room, in step S330.

Proceeding with a chat with the other party assigned to each chat room (S340), if it is confirmed that the chat is completed, proceeds to the end (S350).

In a state where the chat is not completed and continues, when it is confirmed that there is a new chat room allocation request to chat with a new counterpart (S360), it is checked whether or not to allocate more than the determined N chat rooms (S370).

When it is confirmed that the new or additional allocations exceed the determined N chat rooms, the current N chat rooms are sorted in the order of connected time (S380).

Since the messages and log data recorded in the chat rooms having the oldest access time among the sorted chat rooms are recorded and stored in the backup memory unit 220 area and are erased at the same time, the chat rooms are cleaned (S390).

Since the chat room arranged as described above is provided as a chat room requesting a new assignment, a chat is performed with the new counterpart (S400).

If it is determined that the controller 200 of the portable terminal needs to operate the backup chat room, that is, if there is a chat request from the backup counterpart or there is a chat message to be transmitted first, the process (S380). Feedback to (S410).

In other words, the chat rooms currently in operation are sorted again in order of access time, the data of the oldest chat room is backed up and recorded, and the chat room is deleted and cleaned up, and the chat room is newly assigned to the other party. do.

In this case, the backup memory unit 220 is an area separate from the heap memory unit 210 area. In general, the backup memory unit 220 uses a compression method such as compression, but the memory area is large enough for the backup memory unit 220. With this remaining data, since a large number of chat room data having a long connection time can be backed up and recorded, the number of chat room openings continues to increase.

Therefore, there is an advantage of increasing the number of multiple chat rooms opened in the mobile terminal, and if the size of the backup memory is increased, since the chat room is opened by the desired number, and simultaneously connected to chat, there is an advantage that is not limited to the number of chat targets.

In the present invention having the above-described configuration, in the multi-chat using the mobile terminal, the number of connected parties is not limited, and thus there is an industrial use effect of activating the multi-chat and increasing the operation rate and operation rate of the system.

In addition, since there is no limit on the number of simultaneous multi-chat counterparts, there is a convenient effect in that the user's preference is improved by increasing the reliability of the mobile terminal.

In addition, since there are multiple chat rooms that are not limited in number without increasing the capacity of the heap memory unit of the portable terminal, there is a convenient effect of increasing reliability.
