Description

The method for searching other subscribers information by a subscriber of radio access unit in mobile telecommunication system}

The present invention relates to a mobile communication system, and more particularly, to a method for retrieving other subscriber information by a wireless base station subscriber in a mobile communication system.

In general, the mobile communication system 100 includes a plurality of radio access units (hereinafter referred to as RAUs) 120, 130, and 140 as shown in FIG. 1. subscriber terminal, hereinafter referred to as MST (122, 123, 132, 133, 142, 143). The RAUs 120, 130, 140 are interconnected via a network 110. The network 110 may be a wired network or a wireless network.

Each of the plurality of RAUs 120, 130, 140 provides call service to the MSTs 122, 123, 132, 133, 142, and 143 within its communication area 121, 131, 141. Since the MSTs 122, 123, 132, 133, 142, and 143 move from time to time, when the mobile station moves to a communication area of another RAU while subscribed to a specific RAU, it performs a subscription change procedure for a call call. In more detail, for example, when the MST 122 moves from the communication area 121 of the RAU 120 to the communication area 131 of the RAU 130, the MST 122 may move. In order to receive the call service from the RAU 130, the RAU 130 must perform a subscription registration procedure.

Accordingly, when the MST 122 requests subscription registration with the RAU 130, the RAU 130 communicates with the RAU 120 to which the MST 122 has previously subscribed to the MAU 122. Receive information. When the subscription change procedure is completed, the MST 122 receives the call service of the RAU 130, and the MST 122 receives other MSTs 123, 132, 133, 142, through the RAU 130. 143) to perform voice call or data communication.

On the other hand, when the MST 142 subscribed to a specific RAU 140 requests the RAU 140 to process a call with another MST 132, the RAU 140 may not respond. The RAU 140 does not respond to the call processing request of the MST 132 when the MST 132 is not registered or the network 110 is disconnected. In this case, since the RAU 140 does not provide any information to the MST 142, the MST 142 may not know the exact cause of the impossible call processing.

SUMMARY OF THE INVENTION The present invention provides a method for retrieving other subscriber information by a wireless base station subscriber in a mobile communication system in which a mobile terminal subscriber checks information on other subscribers of a wireless base station to determine a cause for call processing impossibility.

DETAILED DESCRIPTION In order to fully understand the present invention, the operational advantages of the present invention, and the objects achieved by the practice of the present invention, reference should be made to the accompanying drawings which illustrate preferred embodiments of the present invention and the contents described in the drawings.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like reference numerals in the drawings denote like elements.

2 is a diagram schematically illustrating a mobile communication system to which the present invention is applied. As shown in FIG. 2, in the mobile communication system 200 to which the present invention is applied, a plurality of RAUs 220, 230, and 240 are interconnected through a network 210. The network 210 may be a wired network or a wireless network. Although only three of the RAUs 220, 230, 240 are shown in FIG. 2, additional RAUs are connected to the network 210.

The RAU 220 provides call services to the MSTs 222-225 in the communication area 221. The RAUs 230 and 240 also provide call services to the MSTs 232 and 233, 242 and 243 in the respective communication areas 231 and 241.

In the mobile communication system 200 configured as described above, another subscriber information retrieval process by the wireless base station subscriber will be described with reference to FIGS. 2 to 4b.

3 is a flowchart 1000 illustrating another subscriber information retrieval process by a wireless base station subscriber in a mobile communication system according to the present invention. 4A is a diagram illustrating a packet configuration when an MST requests subscriber information from a RAU in a process of retrieving other subscriber information by a wireless base station subscriber according to the present invention, and FIG. 4B is a diagram of another packet by a wireless base station subscriber according to the present invention. A diagram illustrating a packet configuration when the RAU transmits subscriber information to the MST in the subscriber information retrieval process.

As shown in FIG. 3, first, a specific MST requests subscriber information from the RAU of a communication area to which it belongs (1001). In FIG. 3, for convenience of description, the MST 225 and the RAU 220 will be described as an example. Thereafter, the RAU 220 receives a subscriber information request signal as shown in FIG. 4A from the MST 225 (1002).

Here, the step 1001 may be performed by inputting a specific function key of the MST 225, for example, a check key + 123 + a completion key. Each component of the packet for the subscriber information request signal of FIG. 4A is described in Table 1 below.

Configuration Contents Header (0 × 7e) Start of message SIZE (0 × 09) The size of the message MSGID (0 × 01) RAU Receive Packet Processing S / W Task DChNo (0 × FF) Incoming Subscriber Channel Number DHwNo (0 × FF) Incoming Subscriber Highway Number Sid, Ssid Message type (subscriber list request: in words) SChNo Sending subscriber channel number SHwNo Incoming Subscriber Highway Number

Next, the RAU 220 analyzes the subscriber information request signal received from the MST 225, and the subscribers, that is, the MSTs 222 to 224 previously subscribed to the communication area 221. Information about the UE is transmitted to the MST 225 (1003). Here, the information about the subscribers includes a telephone number. Description of each component of the packet for the subscriber information that the RAU 220 transmits to the MST 225 is shown in Table 2 below.

Configuration Contents Header (0 × 7e) Start of message SIZE (0 × 15) The size of the message MSGID (0 × 01) MST Receive Packet Processing S / W Task DChNo MST subscriber channel number requesting subscriber information DHwNo MST subscriber highway number requesting subscriber information Sid, Ssid Message type (subscriber list information: word unit) SChNo Sending subscriber channel number SHwNo Incoming Subscriber Highway Number 0 × 74, 0 × 50, 0 × 08, 0 × 1F Subscriber List 0 × 74, 0 × 50, 0 × 08, 0 × 2F Subscriber List 0 × 74, 0 × 50, 0 × 08, 0 × 3F Subscriber List

In Table 2, an example of a subscriber list is shown in FIG. As shown in FIG. 5, the RAU 220 transmits information about other subscribers registered in advance to the MST 225.

The MST 225 receives the subscriber information and stores the information of the subscribers in a predetermined memory (not shown) (1004). Thereafter, the MST 225 searches (1005) whether a desired subscriber exists from the information of the subscribers stored in the memory.

Although not shown in FIG. 3, the MST 225 joins the RAU 220 in more detail as follows. First, when the MST 225 enters the communication area 221 of the new RAU 220, the MST 225 receives a control packet periodically transmitted from the RAU 220 and determines whether to perform a subscription. Thereafter, when the MST 225 generates a subscription packet and transmits it to the RAU 220, the RAU 220 determines whether the MST 225 can subscribe. When the MST 225 is able to subscribe, the RAU 220 receives and stores subscription registration information from another RAU to which the MST 225 has been previously registered through the network 210, and permits subscription. . In addition, when the MST 225 does not have a previously registered RAU, the RAU 220 receives and stores personal information from the MST 225. Thereafter, the RAU 220 provides a call service to the MST 225.

On the other hand, if the subscription registration of the MST 225 is impossible, the RAU 220 does not allow the subscription of the MST (225). For example, when the subscription of the MST 225 is impossible, the personal information received from the MST 225 may not match the personal information stored in the subscriber DB (not shown). In addition, the RAU 220 has a list of all subscribers, and when personal information received from the MST 225 is a phone number that is not in the subscriber list, subscription is not allowed. In addition, the RAU 220 is not allowed to subscribe when the MST 225 is seized, that is, registered in a black list.

As described above, according to the present invention, since the mobile terminal subscriber can receive and retrieve information about other subscriptions from the wireless base station, when a call processing is impossible for a specific subscriber, the reason is that the subscriber is disconnected from the network. You can find out if the subscription is not registered. Therefore, it is possible to provide a more convenient call service to the mobile terminal subscriber.

Although the present invention has been described with reference to the embodiments illustrated in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.

As described above, according to the method for retrieving other subscriber information by the wireless base station subscriber according to the embodiment of the present invention, the mobile terminal subscriber checks the information on the other subscribers of the wireless base station, thereby causing the cause for the inability to process the call. There is an effect that can be identified.
