The present invention relates to a method of subscribing to a mobile wireless coupler of a mobile wireless terminal in a wireless communication system, and more particularly, to a method of preventing network flooding by preventing a mobile wireless terminal from double joining a mobile wireless coupler. will be.

Figure 1 shows the configuration of the network forming a part of the army unit network, the army unit network is composed of five, six such networks. Since the data for all the subscribers of the entire network is so large, it is difficult for the mobile wireless combiner to have a pre-affiliation list. Therefore, the mobile wireless combiner divides the entire network into several network units and manages only a database thereof.

The unit network is mainly composed of a wireless network and a wired network. The wired network is mainly composed of a node switch and the wireless network is composed of a mobile wireless coupler.

The operation of each component shown in FIG. 1 is schematically described as follows. Radio Access Unit (RAU) 13 performs flooding on call requests from Mobile Subscriber Terminal (MST) 15 to find destination subscribers and to signal each other. An exchange for wireless subscribers that connects the call paths after performing a ring. This mobile coupler has eight channels and is a wired / wireless exchange system that connects wired and wireless systems.

The mobile wireless terminal can transmit or receive a call through the mobile wireless coupler in the area of the mobile wireless coupler, and can perform a direct call only between the mobile wireless terminals outside the mobile wireless coupler area. This mobile radio terminal mainly conducts calls through the network. In order to receive the call service through the network, the mobile wireless terminal must be subscribed to the mobile wireless combiner. In other words, when there is a call to find a mobile wireless terminal from the outside, the mobile wireless coupler can be connected only if the mobile wireless terminal is subscribed to it.

Since the mobile wireless terminal is a mobile wireless subscriber, most of the mobile terminals will perform a change of subscription (called a mobile subscription for convenience). That is, when the mobile terminal enters another mobile wireless combiner region while moving in a state of being joined to any mobile wireless combiner, the mobile wireless terminal recognizes that the mobile wireless combiner has moved to another mobile wireless combiner region and performs mobile subscription.

The procedure for performing a subscription by a mobile wireless terminal is as follows. When a mobile radio terminal enters a new mobile radio combiner area, it synchronizes with the new mobile radio combiner through a control packet which is always transmitted by the new mobile radio combiner. Analyze the combiner ID field to determine whether a subscription should be performed.

The mobile wireless terminal generates a subscription packet by including necessary information such as its own unique number in the packet contents and transmits it to the mobile wireless combiner. In addition, the mobile wireless combiner analyzes the information on the subscription request of the mobile wireless terminal and floods the subscriber request search message to the entire network to prevent the dual subscription state with the mobile wireless combiner. . As a result, when the mobile wireless combiner previously subscribed receives such a message, it deletes the subscriber from its local subscriber list and delivers an acknowledgment message to the mobile wireless combiner to subscribe. The mobile wireless combiner intending to receive the transmission transmits a packet called a subscription transmission to the mobile wireless terminal, and the mobile wireless terminal receives the packet.

As described above, when the subscriber discovery message to prevent the dual subscription in the mobile wireless coupler is flooded into the entire network, all network systems must perform a procedure for comparing their subscriber list data. As a result, the entire network must perform this procedure for one subscriber, which is very inefficient.

Accordingly, an object of the present invention is to provide a method for preventing network flooding by preventing dual subscription of a mobile wireless terminal to a mobile wireless coupler.

In order to achieve the above object, the present invention relates to a mobile wireless coupler subscription control method of a mobile wireless terminal, wherein the mobile wireless terminal that attempts to subscribe to a mobile wireless coupler is currently subscribed to a subscription packet including the mobile wireless combiner subscription information. Sending a message, requesting the current mobile wireless coupler to delete information related to the mobile wireless terminal that is attempting to subscribe to the previous mobile wireless coupler, and receiving the information deleting request from the previous mobile wireless combiner. Inspecting a list of local subscribers, sending information about the mobile wireless terminal to the mobile wireless combiner to be subscribed to, and deleting the corresponding subscriber; and granting or disallowing subscription to the mobile wireless terminal from the mobile wireless combiner currently subscribed to; Characterized in that the response packet is sent All.

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

First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals have the same reference numerals as much as possible even if displayed on different drawings. In addition, in the following description, many specific details such as components of specific circuits are shown, which are provided to help a more general understanding of the present invention, and the present invention may be practiced without these specific details. It will be obvious to those skilled in the art. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

2 is a diagram illustrating a joining procedure of a mobile wireless coupler of a mobile wireless terminal according to the present invention. This sign-up procedure represents the signaling of a mobile radio terminal, the mobile radio combiner to be subscribed to and the mobile radio joining period previously subscribed. Packets transmitted and received between the mobile wireless coupler and the mobile wireless terminal period are as shown in (3a)-(3c) of FIG. Information of the control packet transmitted by the mobile wireless combiner is as follows.

. Control Packet ID

. Affiliation ID (corporate, node exchange or unit exchange, mobile wireless combiner)

. Reference data

. TOD (Time of Day)

. Hop Pattern

. Channel Status

. Channel occupied mobile terminal ID

The joining operation of the mobile wireless terminal is started by analyzing the belonging ID in the information of the control packet. When receiving the control packet, the mobile terminal analyzes the belonging ID field and compares it with the ID currently being stored. If the two IDs are different, the mobile terminal performs the joining procedure. When attempting to join, as shown in (3a) of FIG. 3, the mobile wireless terminal transmits the mobile wireless combiner ID which it has previously subscribed to in the subscription packet. The mobile wireless combiner which receives this prevents the dual subscription of the mobile wireless terminal by instructing the mobile wireless combiner to which the mobile wireless terminal to which it is previously subscribed deletes the information on the mobile wireless terminal.

Upon receiving such an order, the mobile wireless combiner finds the corresponding subscriber in its local subscriber list, delivers detailed information about the subscriber to the mobile wireless combiner performing the subscription, and deletes the subscriber from its local subscriber list. In addition, the mobile radio terminal requesting subscription receives a response packet from the mobile radio combiner and terminates the subscription.

If we explain here whether or not to join,

The mobile wireless combiner receives a variety of information from the subscriber to subscribe to determine the subscription, one of which is a personal code (personal code). This personal information is a number used in pairs with a phone number and acts like a password. If the personal information transferred to the mobile wireless combiner does not match the personal information stored in the subscriber database of the mobile wireless combiner, subscription is not allowed. The mobile wireless combiner also has a database of all subscribers, that is, a subscription list.

Therefore, when the subscriber of the mobile wireless combiner requests subscription, the subscriber's telephone number transmitted to the mobile wireless combiner cannot be temporarily subscribed to the phone number that is not in the subscription list. In addition, the mobile wireless combiner manages a black list in case the mobile wireless terminal is seized. If the phone number of the subscriber to be registered is registered in the black list, the mobile wireless combiner cannot be subscribed to.

Each signal shown in FIG. 2 represents the above operations, which will be described in detail as follows.

Mobile wireless combiners are divided into several tasks in software, one of which is an administration task. Reference sign MSF denotes a mobile wireless combiner, RAU denotes a mobile wireless terminal, and Admin denotes such management work. The management task currently manages all databases required by the mobile combiner. Since the mobile wireless coupler is a mobile subscriber, it is not a subscriber that is used in a fixed state by joining one mobile wireless coupler.

In other words, in order to perform a call by moving to another mobile wireless combiner area, a new join operation must be performed to the mobile wireless combiner of the moved area. In the process of performing a subscription, the mobile wireless terminal transmits a subscription request packet, and receives it from the call processing unit of the mobile wireless combiner, analyzes the packet, and inquires through a management operation when the subscription request packet is received. This signal is indicated by the reference AFFREQ. At this time, if the management task is not in the list of subscribers, a flood search is performed to contact another mobile wireless combiner. The signal FS indicates this signal.

This flood search signal FS is transmitted only to the mobile wireless combiner that has been subscribed to. This signal FS is transferred back to the management work of the existing mobile radio coupler and found in the local subscriber list. If there is a subscriber list of subscribers in another mobile wireless combiner, a predetermined signal RMSH is sent in response to the flood search signal FS. In the management operation of the mobile wireless combiner to be subscribed to, the subscriber information is requested from the mobile subscriber coupler. This signal is indicated by the reference MOVEREQ. In response to this, information about the subscriber is transmitted. And deletes the list for this subscriber from his local subscriber list. This signal corresponds to the reference MOVE.

In addition, the pc-check in the mobile wireless coupler to which the user wants to subscribe cannot know whether the personal code received from the subscriber is correct because there is no subscriber information in his database. Therefore, in order to inquire this to the mobile wireless combiner with the subscriber list, the subscriber's phone number and personal information are delivered to the MOVEREQ message and checked in the management operation of the mobile wireless combiner with the subscriber list.

As described above, the present invention does not flood the subscriber search message to the entire network when the mobile combiner receives the subscription request, and floods only the previously subscribed mobile wireless combiner with the mobile combiner ID in the subscription packet, thereby flooding the entire network. By reducing the load (load) by, there is an advantage that can effectively prevent the double subscription.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.
