DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a position registration control method for moving a position registration area when a cordless terminal is on standby and when turning on the power after turning off the power. Since the cordless system is cordless, the terminal often moves due to being carried, and the power may be turned off at night to prolong the use time. In addition, when the call area is out of sight and goes out of the service area, an out-of-service indication is displayed. Therefore, it is also important to reduce the amount of processing at that time.

[0002]

2. Description of the Related Art In a location registration control of a cordless exchange system, when a location registration is transmitted from a terminal, the terminal transmits the location registration information to a main body exchange without setting state type information at the time of the transmission. For this reason, the main unit exchange notifies the cordless terminal that the status of the main unit does not match the status of the terminal when receiving the location registration information (for example, when the terminal is turned off, it is not possible to notify the terminal when e-mail arrives at the terminal, etc.) ), The terminal information of the main body is uniformly transmitted to the terminal as a recovery process.

It is not necessary to perform the above-described terminal recovery process, for example, when the terminal is in the location registration area while the power is on, the terminal is notified immediately when the corresponding condition occurs. This is necessary at the time of location registration, such as when the power is turned on from the terminal or when moving from outside the service area to the service area, because the information may not be notified to the terminal when the corresponding condition occurs. However, in the conventional location registration control method, when the location registration requirement of the terminal occurs, the location registration request information is uniformly generated without any state type information in any state.

[0004]

As described above, in the current location registration control method, the location registration process is uniformly executed regardless of the location registration occurrence type condition of the terminal. Therefore, in order to eliminate inconsistency between the information recognized by the terminal and the information recognized by the main exchange, each time the location registration occurs, the corresponding information recognized by the main exchange (for example, incoming mail information or absence message Information, etc.) to the terminal.

[0005] Therefore, the amount of information transmitted to the terminal increases in proportion to the number of times of location registration of the terminal, which has a large effect on the processing capacity of the main unit exchange. In view of the above-described problem, the present invention adds a location registration occurrence condition type at the time of terminal location registration, so that there is no mismatch between the information recognized by the terminal and the information recognized by the main unit exchange. When a location registration occurs (for example, when the location is registered by moving the standby location registration area in a normal power-on state), the recovery process (the process of sending from the exchange to the terminal) is not transmitted.

Therefore, an object of the present invention is to transmit the type of condition to be generated to a main exchange when a location registration condition of a cordless terminal occurs, and the main exchange determines the type and transmits unnecessary information to the terminal. Therefore, it is an object of the present invention to improve the processing capacity of the main unit exchange and reduce redundant processing in a terminal.

[0007]

The method of the present invention comprises steps 1 to 6 as shown in FIG. The contents are as follows. (1) Step 1 (S1) When a location registration occurs, the cordless terminal analyzes and determines the occurrence type condition. (2) Step 2 (S2) After the analysis determination, the location registration occurrence condition type information is calculated and added to create location registration information. (3) Step 3 (S3) A location registration request sequence is generated using the created location registration condition type information.

(4) Step 4 (S4) When the exchange receives the position registration request information in the position registration request sequence, first, the exchange sets the position information of the corresponding terminal in the main memory. (5) Step 5 (S5) Next, an analysis is performed to determine whether registration information corresponding to the corresponding location registration occurrence terminal is set in the exchange, and if there is information, the type of the previous location registration request is determined. It is determined whether the information is to be transmitted to the terminal according to. As a result of the judgment and identification, if necessary, the information set in the exchange is transmitted to the corresponding location registration generating terminal together with the location registration acceptance information. If unnecessary, only the location registration reception information is transmitted to the corresponding terminal.

(6) Step 6 (S6) Upon receiving the location registration acceptance information, the location registration generating terminal first sets the location registration information in a specified area of its own cordless terminal. After that, it analyzes the received information to determine whether the information for the local terminal has been set in the main unit exchange, and if so, notifies the user of the information, that is, executes the display on the display unit I do.

[0010]

According to the present invention, when a location registration request is issued to the main exchange when a location registration request condition is generated, the type of the generated request condition is also transmitted. The information of the exchange is transmitted to the terminal. Therefore, unnecessary information is not transmitted, which can contribute to the improvement of the processing capacity of the main unit exchange, and the terminal does not need to perform unnecessary processing.

[0011]

FIG. 2 is a block diagram showing a configuration of a cordless exchange system to which the present invention is applied. As shown in the figure, the mobile switching center 1 and a plurality of base stations 2 are connected by wire, and the base station (CS) 2 and the terminal (PS) 3 are connected by radio. When the terminal leaves the location area and moves to another location area or when the power is turned on, the terminal performs location registration and performs a series of processing. An example of the above processing outline will be described with reference to FIGS. 3 to 6. First, a process when the power of the cordless terminal is turned on will be described.

(1) When the power is turned on, the cordless terminal receives radio information from a base station located above the corresponding location area. (2) Next, a location registration request sequence is generated to register the location information of the terminal itself in the main exchange. At the time of this position registration, the cordless terminal determines the condition of position registration at power-on from power-off, and sets `` position registration at power-on '' information as position registration request type information in the position registration request information, Generate a location registration sequence (FIGS. 3 to 6)
reference).

(3) When receiving the information of the location registration sequence, the main exchange sets the location information of the corresponding cordless terminal in the main memory in the own exchange. Next, it is determined whether registration information (for example, incoming mail or absence message incoming information, etc.) for the location registration occurrence cordless terminal is set. If the registration information exists, analyze the location registration request type information in the location registration request information received earlier,
It is determined whether the information needs to be transmitted to the terminal. In this case, the information needs to be transmitted to the terminal because the location is registered after the power is turned off, and the information is edited.

(4) After editing the information, the main body exchange transmits the corresponding information to the location registration generating cordless terminal in accordance with the location registration reception sequence. (5) The cordless terminal, upon receiving the information of the location registration reception sequence, first rewrites the location registration information of its own terminal, then analyzes the registration information from the main body to its own terminal, and if the information exists, it follows the information. Is set in the terminal display or the corresponding registration memory.

Next, when the power of the cordless terminal is turned on,
The processing at the time of moving between the location registration areas is shown. (1) When the power is turned on, the cordless terminal is in a normal standby state or a callable state. (2) In this state, at the time of location registration by moving the location registration area of the terminal (when the movement weakens the radio electric field strength in the current standby area and moves to a radio base station in which the electric field strength in another area is strong), the terminal switches to the main exchange automatically. A location registration request sequence is generated to register location information of the terminal.

At the time of the location registration, the cordless terminal judges the condition of the location registration when moving between the location registration areas in the power-on state, and sets the location registration request type information in the location registration request information to “Move between location registration areas”. Information is set, and a location registration sequence is generated (see FIGS. 3 to 6). (3) Upon receiving the information of the location registration sequence, the main exchange sets the location information of the corresponding cordless terminal in the main memory in the own exchange.

Next, it is analyzed and determined whether registration information (for example, information on incoming mail or absence message, etc.) for the cordless terminal whose location has been registered has been set. If the registration information exists, the location registration request type information in the previously received location registration request information is analyzed to determine whether the information needs to be transmitted to the terminal. In this case, it is not necessary to transmit the information to the terminal because the position registration is performed when moving between the position registration areas (when the above-described condition of the registration information to the main unit exchange occurs, the corresponding terminal is notified to that effect). .

(4) For this reason, the main exchange edits only the location registration reception information, and then transmits the corresponding information to the location registration generation cordless terminal in accordance with the location registration reception sequence. (5) The cordless terminal, upon receiving the information of the location registration reception sequence, first rewrites the location registration information of its own terminal, then analyzes the registration information from the main body to its own terminal, and if the information exists, the information In accordance with the above, the display on the terminal and the corresponding registration scale are set to that effect. On the other hand, if there is no registration information for the own terminal, the process ends only with the setting of the position information.

FIGS. 3, 4 and 5 will be supplementarily described. FIG. 3 is a diagram showing the contents of a location registration request message in the method of the embodiment. In the figure, the information element from "protocol identifier" to "PS number" is the same as the conventional method, but in the method of the present invention, the item of "location registration type" is added. In this item, as shown in the lower part of the figure, the position registration type is indicated by “1” or “0” of each bit level.

FIG. 4 is a diagram showing the contents of a location registration acceptance message in the method of the embodiment. In the figure, from the "protocol identifier" in the information element to "location registration area report"
Up to this point, the method is the same as the conventional method, but in the method of the present invention, a section of “registration status notification report” is added. And
The content of this section is as exemplified below. The registration information identifier number is assigned a value for each service, and the information is discriminated and processed by the exchange and the terminal, respectively, and processed. When a plurality of pieces of information are registered in the main exchange, a plurality of pieces of information are transmitted. FIG. 5 is a diagram illustrating a configuration of a physical slot in a wireless section in the method according to the embodiment.
Each of the above messages is set and transmitted in the slot I (FACCH) portion.

[0021]

According to the present invention, when a location registration condition of a cordless terminal occurs, the type of the condition is transmitted to the main exchange, so that the main exchange determines the type and transmits unnecessary information to the terminal. It is possible to improve the processing capacity of the main body exchange and reduce redundant processing in the terminal.
