In particular, the mobile position data of the portable terminal for providing the movement position data to grasp the movement route of the portable terminal. It relates to a providing method.

In general, a wireless telephone network system wirelessly establishes a network between a fixed station (or a base station, hereinafter referred to as a fixed station) and a portable terminal (or mobile phone) to transmit and receive data. The portable terminal adopting the European wireless communication standard (DECT) is a type of mobile phone used for personal mobile communication in such a wireless telephone network system.

In a wireless telephone network system employing the deck method, the fixed station is generally configured to perform transmission and reception with a portable terminal located within a radius of about 300M. These fixed stations have their respective fixed part Mac layer IDentities (FMIDs) at fixed locations, which are assigned to the station when the terminal registers with the station or when the terminal enters its area. Sent to the terminal, the terminal selects and registers an adjacent fixed station using the unique number of the fixed station. The unique number of the fixed station is deleted from the terminal when handover to another fixed station due to the movement of the terminal. That is, when the mobile station moves to a region where the reception signal of the corresponding fixed station is weakened, the terminal selects an adjacent fixed station having the strongest reception strength, and when a handover is performed to the selected fixed station, the current registration is performed. The unique number for the fixed station has been removed, and the unique number of the fixed station shown in the new registration is retained. As a result, the geographical location of the terminal can be known but the mobile situation cannot be understood.

Accordingly, an object of the present invention is to provide a mobile location data providing method of a mobile terminal for providing a mobile location data so that the mobile station data can be identified by storing a unique number of a fixed station that has been registered once in a registration order.

And an antenna 110 for outputting the received data to the reception processor 111, and a timer 113 for supplying current time data.

2 is a flowchart of a method for providing movement position data of a portable terminal according to the present invention in a deck type portable terminal configured as shown in FIG.

Next, the operation of the embodiment according to the present invention will be described with reference to FIGS. 1 and 2.

First, when the power of the portable terminal is turned on by the power supply of the power supply unit 101 in step 201, the central processing unit 103 proceeds to step 202 to read an initial value stored in the memory 108. Take out and initialize each piece of hardware.

When the hardware initialization in the terminal is completed, the central processing unit 103 proceeds to step 203 to select the nearest fixed station. In order to select the nearest fixed station, as in the past, the central processing unit 103 examines the electric field strength received from 10 fixed stations from the radio channels 0 to 9 applied from the receiving processing unit 111, and among them, the strongest wireless signal. Select a fixed station (or wireless base station) that emits (the highest field strength of the received signal). When the fixed station is selected, the central processing unit 103 proceeds to step 204 to extract the unique number of the selected fixed station, and then proceeds to step 205 to store it in a predetermined area of the memory 108. Here, the unique number of the fixed station is applied to the central processing unit 103 by using the MAC frame transmission time through the antenna 112 and the receiving processing unit 111 when the received signal field strength is investigated, and the central processing unit 103 is the receiving processing unit 111. ) Can recognize the data corresponding to the unique number of the fixed station among the data received through the header area of the received data applied in a predetermined byte unit.

In step 206, the central processing unit 103 reads the time data set in the timer 113 and stores the time data in the predetermined area of the memory 108. At this time, the stored time data is stored to be read together with the unique number of the fixed station currently input. If the time data is stored, the process proceeds to step 207 to register with the selected fixed station. The registration process checks the current time slot usage status of the station, checks whether there is an empty time slot, and then performs the registration procedure. When the registration process is completed, the portable terminal stays in a stand-by state. In the standby state, the portable terminal performs call formation according to whether there is a paging signal (called a call signal) from the fixed station and whether the portable terminal user requires a connection to a specific subscriber.

That is, the process proceeds to step 208 to check whether a paging signal is received from the fixed station through the antenna 110. As a result of the check, if there is a paging signal, access is required from the fixed station. In step 209, physical layers (PHL), medium access control (MAC) layers, and DLC After the data link control (layer, network layer) is sequentially connected, the call is terminated by one of the call cutting situations, and the connected layer is disconnected in the reverse order to release the right to use the wireless channel.

However, if the paging signal does not exist in step 208, the process proceeds to step 210 and the operator checks whether the connection request signal is applied through the key data input unit 102. In this case, when the connection request signal is applied, the process proceeds to step 209 to perform the connection and release processing as described above.

However, if the access request signal by the operator is not applied in step 210 or the connection and disconnection processing is completed through the call in step 209, the state of the terminal is checked through steps 211 and 212.

First, in step 211, if there is an error for the battery used as a power supply source, and if an error occurs, a warning process is performed so that an operator can recognize it, and then the process proceeds to step 212 to perform the reception signal as performed in step 203. The adjacent station is selected based on the field strength.

When the fixed station is selected, the process proceeds to step 213 to extract the unique number of the fixed station applied through the reception processing unit 111 as in steps 204 and 205, and to the predetermined area of the memory 108 as in step 205. Save it. In this case, the predetermined area stored in the memory 108 is stored at a position where the next sequence data of the data stored in step 205 can be read. If the unique number of the fixed station is stored, the process proceeds to step 214 where the current time data set in the timer 113 is read out as in step 206 and stored in a predetermined area of the memory 108. In this case, the central processing unit 103 controls the stored area to be stored in a position that can be read together with the unique number stored in operation 213. If the current time data is stored, the process proceeds to step 215.

In step 215, as in step 207, registration processing of the terminal is performed to the fixed station selected in step 212.

The registration process is performed in the same manner as in step 207. However, when a fixed station selected from the station in step 203 is selected due to the movement of the terminal, the registration process is performed by using a handover function. In other words, after releasing what has been registered in step 207, a new registration process is performed. When this registration is completed, the flow proceeds to step 216.

In step 216, the central controller 103 determines whether a control command (a position data read request command) for identifying the movement position data of the terminal is applied through the key data input unit 102. If it is determined that the position data read request command is not authorized, the flow returns to step 208. However, if the position data read request command is granted, the flow proceeds to step 217 to read the unique number and time data of the fixed station stored in the predetermined area of the memory 108. At this time, the reading order is read sequentially in the order of saving. When the data is read, the central processing unit 103 proceeds to step 218 and controls the display to be displayed on the LCD display unit 109.

In operation 219, it is checked whether a control command for terminating reading of position data from the key data input unit 102 has been applied. As a result of the check, if the read-out command is granted, the process of outputting the position data ends and returns to step 208. However, if the read end command is not applied, the pointer of the position data to be read from the memory 108 is changed in step 220 such that the position data corresponding to the next order of the position data read in step 217 is read.

If the pointer is changed, the process proceeds to step 221 and checks whether the power supply of the terminal is on. If the pointer is in the on state, the process proceeds to step 217 and repeatedly reads and outputs position data corresponding to the next sequence. However, if the power is off, the terminal is not in the standby mode, thereby terminating all operations of the terminal.

As described above, the present invention stores a unique number and a registration time of a fixed station in which a terminal has been registered in a wireless telephone network system, and outputs it when the mobile station of the terminal attempts to determine the movement of the terminal. There is an advantage to this.
