Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a configuration of a mobile communication terminal having a short range wireless network function according to the present invention, and describes a configuration of a terminal having a ZigBee as the short range wireless network device.

Referring to Figure 1, the apparatus of the present invention is largely composed of a mobile communication unit 100 and a short-range wireless network unit 200, the mobile communication unit 100 is a phone control unit 101 which is provided to the existing mobile communication terminal ) And various RF related functional blocks 102-105 are added.

The phone control unit 101 is commercially provided as a single integrated circuit, and is generally referred to as an MSM chip, and includes dedicated hardware (modem) for processing communication, a digital signal processor, and a general purpose microprocessor. Functionally, the phone control unit 101 controls voice and data communication, and controls the entire system according to an operation signal or an operation state input from a keypad.

The other RF functional blocks 102 to 105 are not significantly different from the operation in the general mobile communication terminal, and thus description thereof will be omitted and the configuration of the short range wireless network unit 200 will be described in more detail.

The short-range wireless network unit 200 includes a ZigBee transceiver module 201, a ZigBee transceiver module 202 for modulating and transmitting a ZigBee signal, and a ZigBee network module including a protocol stack of each layer for ZigBee network communication. 203 and an application program unit 204 for transmitting and receiving shared information with the mobile communication unit 100 and configuring a mesh network.

The Zigbee transmission / reception module 202 may include a receiver 202a for receiving a Zigbee signal from the antenna 201, a transmitter 202b for transmitting a Zigbee signal through the antenna 201, and the Zigbee signal transmitter / receiver And a modem 202c for demodulating and demodulating Zigbee signals transmitted and received via 202a and 202b.

The memory 105 stores information commonly used by the phone control unit 101 of the mobile communication unit 100 and the application program unit 204 of the short range wireless network unit 200.

The ZigBee network module 203 forms ZigBee RF, Media Access Control (MAC), and network layer hardware in the terminal. As a result, the mobile communication terminal can simultaneously serve as a coordinator or a full function device (FFD) in a mesh network.

The application program unit 204 allows a terminal to be initialized as a coordinator or an FFD, and manages a list of FFD terminals (terminals of a partner and a partner who do not want to meet) with each MIN (Mobile Identification Number). It searches whether the FFD terminal on the network exists and performs a predetermined appropriate operation for providing the encounter information service upon discovery. In addition, operations for network handover and network establishment are also performed.

FIG. 2 is an exemplary diagram showing a setup frame configuration of a Zigbee network layer transmitted for network setup in the present invention. In the present invention, a predetermined one bit of 10-15 bits, which is a reserved area of a frame control flag in a network setup frame, may be used. Bit 10) is used as the bit to set the 'search block mode'.

For example, when the 'blocking search mode' setting bit is set to '0', it is enabled, and when it is set to '1', it is disabled. Enable or disable what is retrieved.

That is, the coordinator terminal registers the FFD terminals connected to its network to the list and broadcasts the lists to all the FFD terminals in the network. If a certain FFD terminal is connected to the network, the coordinator terminal enables the 'search blocking mode'. In the case of setting, it receives the information of the other terminal connected to the network, but blocks its information from being transmitted to the other terminal.

Therefore, the coordinator terminal needs to separately manage the list of FFD terminals connected to the network and the list of FFD terminals connected to the network but not revealing their information.

3 is a state diagram illustrating a meeting information service method using a mobile communication terminal according to the present invention. As shown in FIG. 4, a terminal existing in a predetermined network area includes one terminal acting as a coordinator according to a setting, and the terminal. It is composed of terminals to be connected to and operate as FFD.

Each terminal stores a mobile identification number (MIN) or an electronic serial number (ESN) of the counterpart terminal and manages the counterpart list by dividing it into a counterpart list and an unwanted counterpart list.

Referring to FIG. 3, an FFD terminal intending to use the encounter service of the present invention must first join a network of a corresponding region. To this end, the FFD terminal transmits a network setup frame as shown in FIG. 2 to the coordinator terminal to request a network connection. At this time, the 'blocking search mode' is set by setting the bit value (1 or 0) of the frame control flag in the network setup frame (S101).

That is, according to the setting of the 'discovery blocking mode', as described above, the coordinator terminal is provided with information of other terminals connected to the network, and the list of FFD terminals to provide its own information to other terminals (bidirectional information). Provision list) and a list of FFD terminals (unidirectional information provision list) which are provided with information of other terminals connected to the network but do not provide their own information to other terminals.

At this time, the network connection request method is a non-beacon method.

Meanwhile, in the above embodiment, the coordinator in the network area that provides the meeting service is described as being performed by the terminal. However, it is obvious that the mobile communication base station may play a role of the coordinator when the network area is extended.

Therefore, when the user who used the meeting service moves to another network area and is handed over, the network coordinator providing the meeting service must also be changed to the coordinator of the other area. Thus, the handed-over terminal accesses the network to the coordinator of the moved area. You must send a request frame to rejoin that network.

The coordinator terminal successfully receiving the network connection request as described above determines whether to set the search blocking mode and stores and manages the ID number of the counterpart FFD terminal in the corresponding list (bidirectional or unidirectional information provision list) managed by the coordinator (see FIG. S102-S104).

Subsequently, beacon signals are sequentially transmitted to the FFD terminals having ID numbers registered in the list at predetermined intervals (S105), and the corresponding FFD terminals are received on the network by receiving the response signal (Beacon Ack). It periodically checks whether it is connected and updates the list (S111). Then, corresponding contact information (bidirectional information provision list) is transmitted to the terminals according to the management list (S106 to S108). The encounter information is preferably transmitted when the coordinator transmits a beacon signal.

In this case, the output beacon signal is transmitted to the FFD terminals in a 1: 1 manner (Peer to Peer), but the encounter information may be transmitted in a broadcast manner since only the bidirectional information providing list is transmitted.

The FFD terminals provided with the contact information (interactive information providing list) compare the information with information of the 'contact partner list (desired contact list, unwanted contact list)' that they hold (S109). If the terminal in its 'contact partner list' is also in the contact information (interactive information providing list), the terminal is in the network area.

Accordingly, the terminal outputs an alarm when the desired meeting partner or the unwanted meeting partner is in the same network according to the setting of the meeting information service function (S110).

In the above, preferred embodiments of the present invention have been described with reference to the accompanying drawings. Here, the terms or words used in the present specification and claims should not be construed as being limited to the common or dictionary meanings, but should be interpreted as meanings and concepts corresponding to the technical spirit of the present invention.

As described above, the present invention provides a mobile communication terminal having a short range wireless network function and a meeting information service method using the same. The mobile communication terminal includes a short range wireless network device in the mobile communication terminal and forms a mesh network between the terminals. For the purpose of providing

In addition, the present invention by identifying the information of the terminals in the network, it is possible to distinguish between those who want to meet and those who do not want to inform the user, there is an effect of creating a new service from the operator perspective, from the user's perspective It has the effect of providing new entertainment and convenience at the same time.
