Description

Method of Simultaneous Call Processing in Subscriber Registration Device of Wireless Subscriber Network {METHOD FOR PROCDSSING THE SAME TIME CALL IN WIRELESS LOCAL LOOP OF SUBSCRIBER'S INTERFACE APPARATUS}

The present invention relates to a method for processing a call in a wireless local area network (WLL), and more particularly, to a method for processing a call in a subscriber matching device of a wireless subscriber network.

In general, a wireless subscriber network refers to a device that accommodates a plurality of subscribers using a wireless terminal matching device in a home or office of a company, and processes a call wirelessly as a mobile communication terminal through a base station. Such a wireless subscriber network will be described with reference to FIG. 1 is a block diagram of a system configuring a typical wireless subscriber network.

The terminal matching device 20 is connected to a plurality of communication devices 10, 12,..., 14 via wires, and simultaneously forms a wireless link to the base station 30. Each of the communication devices 10, 12,... 14 may perform communication in the same manner as in the case of a wired connection using a terminal matching device. Therefore, the terminal matching device 20 converts the data received from each communication device 10, 12, ... 14 into a radio signal and transmits. This forms a wireless link with the base station 30, it is possible to transmit and receive data. The base station 30 forms a wireless link with a plurality of terminal matching devices existing in its wireless signal transmission area, and operates in the same manner as when transmitting and receiving data to a general mobile communication terminal. The control unit 40 is connected to a plurality of base stations by wire and performs the connection between the base stations and the mobile communication switching system, control of the base stations, statistics, and the like. The mobile communication switching system is connected to at least one control station and a public network (PSTN), and forms a link of a call when a call is requested from the control station or, when a call is received, connects it to a terminal matching site through the control station and the base station. It performs the function.

In such a wireless subscriber network, the terminal matching device 20 is defined by being classified into a single signal mode and a multiple signal mode according to the usage of the signal channel.

Single signal mode is a method of allocating both a signal channel (Signal Channel) and traffic channel (Traffic Channel) for each call. In detail, it is a method of independently setting and maintaining multiple calls by allocating both a signal channel and a traffic channel to each call. Therefore, when the single signal mode is used, even if each communication device (10, 12, ... 14) requests a call at the same time it can accommodate. However, for this purpose, the hardware configuration of the terminal matching device 20 requires a modem and a wireless processing unit corresponding to each communication device. In this case, therefore, there is actually one terminal matching device 20, but the internal configuration is as if each terminal matching device exists in correspondence with each communication terminal 1: 1. Therefore, there is a problem that the price of the terminal matching device is increased.

In the multiple signal mode, traffic channels use respective channels and signal channels are commonly used. As such, the traffic channel is used separately, and when the signal channel is used separately, a modem and a wireless processor are not required for each communication device as in the single signal mode. However, there is a limitation that a previously set signal channel must exist for the multiple signal mode to operate. That is, when several communication devices simultaneously request a service, they cannot all be accommodated. This will be described with reference to FIG. 2.

2 is a signal flow diagram when different communication devices request a service at the same time in a terminal matching site when using the multi-signal mode.

The case where the communication device 10 of the first subscriber and the communication device 12 of the second subscriber request the call to the terminal matching device 20 at the same time will be described. The first subscriber communication device 10 outputs a service request signal to the terminal matching device 20 in step 100. Then, the terminal matching device 30 generates a channel request signal to the base station 30 and transmits it as a wireless signal. In this case, when the terminal matching device 20 receives the service request signal from the second subscriber communication device 12 in step 104, it cannot accept the service request. Because the state of the terminal matching device 20, the service is requested by the first subscriber communication device 10, but the signal channel and traffic channel is not yet created. Therefore, when the multi-signal mode is used, the terminal matching device 20 outputs a service reject signal to the second subscriber communication device 12 in step 108. This process is irrelevant whether the terminal matching device 20 receives a Channel Request Ack signal from the base station 30 in step 106.

Then, the second subscriber communication device 12 recognizes that the communication is not possible, and the terminal matching device 20 performs a subsequent process for setting up a call of the first subscriber communication device 10. Thereafter, the base station 30 transmits a channel assignment signal to the user terminal matching device 30 in step 110. This process is performed using the paging channel. Then, a signal channel is formed, and through the generated signal channel, the base station 30 outputs a received ready signal to the terminal matching device 20 in step 112. Then, the terminal matching device 20 transmits a reception ready signal to the base station 30 in step 114 using the formed signal channel. Thereafter, the terminal matching device 20 transmits a connection request signal to the base station 30 in step 116. Accordingly, the base station 30 transmits a connection response signal to the terminal matching device 20 in step 118. This completes the creation of the signal channel. Then, the terminal matching device 20 outputs a service response signal to the first subscriber communication device 10 in step 120. In other words, the first subscriber communication device can form a normal call.

As described above, when the single signal mode is used, there is a problem in that the price of the terminal matching site 20 is increased. Also, when the multiple signal mode is used, when a plurality of subscribers simultaneously request a service, one connected first There was a problem that only subscribers could receive services.

Accordingly, an object of the present invention is to provide a method for accommodating a service for all subscribers requesting the service even when multiple subscribers request the service at the same time when using the multiple signaling mode in the subscriber matching device of the wireless subscriber network. .

The present invention provides a multi-call processing method in a terminal matching device of a wireless subscriber network in which a service request signal is received from different subscriber communication devices without a signal channel formed between the terminal matching device and the base station. If necessary, wait for the subscriber communication devices which output the service request signal later among the communication devices, and perform a process for setting a traffic channel to be allocated to the subscriber communication device which outputs the service request signal first, and the first service. According to the order in which the service request signal is received, the process of establishing a traffic channel to the communication device of the subscribers who output the service request signal later by using the signal channel generated when the traffic channel is established in the communication device of the subscriber which outputs the request signal Perform.

In addition, the flow of the signal for setting the traffic channel from the terminal matching device to the base station, the first step of receiving a signal of the channel request response signal after transmitting a channel request signal, and when the channel request response signal is received A second step of receiving a channel assignment signal, a third step of receiving a ready signal after receiving the channel assignment signal, and sequentially receiving a ready signal and a connection request signal to the base station after receiving the ready signal And a fifth step of outputting a service response signal to a corresponding subscriber communication device when an access response signal is received after receiving the access request signal.

The first signal flow process for establishing a traffic channel from the terminal matching device to the base station is performed through the paging channel in the first to third steps, and the fourth and fifth steps in the signal channel. Characterized in that made through.

2 is a signal flow diagram when different communication devices simultaneously request services in a terminal matching site in a multiple signal mode according to the prior art;

3 is a signal flow diagram for providing a service when different subscribers simultaneously request a service according to an exemplary embodiment of the present invention.

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

3 is a signal flow diagram for providing a service when different subscribers simultaneously request a service according to an exemplary embodiment of the present invention. Hereinafter, the flow of a signal for providing a service when a plurality of subscriber communication devices connected to the terminal matching site 20 requests a service according to the present invention will be described in detail with reference to FIGS. 1 to 3. In addition, in the following description, the first subscriber communication device 10, the second subscriber communication device 12, the terminal matching device 20, and the base station 30 are the same as those of FIG. Only the internal operation of the terminal matching device 20 is changed as shown in the flowchart of FIG.

The first subscriber communication device 10 outputs a service request signal to the terminal matching device 20 in step 100. Then, when receiving the service request signal, the terminal matching device 20 generates and outputs a channel request signal to the base station 30 through the paging channel in step 202. At this time, if a service request signal is received from the second subscriber communication device 12 in step 204, the process is to wait for the communication device of the subscriber who has transmitted the service request signal. Thereafter, the terminal matching device 20 receives a Channel Request Ack signal in step 206. The base station 30 transmits the channel request response signal using the paging channel, and then transmits a channel assignment signal to the terminal matching device 20 using the paging channel in step 208.

This process establishes the signal channel. When the signal channel is formed, the base station 30 generates and outputs a reception ready signal (RR) to the terminal matching device 20 through the formed signal channel in step 210. When the reception ready (RR) signal is received through the signal channel, the terminal matching device 20 transmits the reception preparation (RR) signal to the base station 30 in reverse in step 212. This completes the formation of the signal channel. Thereafter, the terminal matching device 20 proceeds to step 214 and transmits a connection request signal to the base station 30. In this manner, the base station 30 outputs a connection response signal to the terminal matching device 20 in step 216. Through this, a signal channel is formed between the terminal matching device 20 and the base station 30, and common data can be transmitted and received through the signal channel. The terminal matching device 20 outputs a service response signal to the first subscriber communication device 10 in step 218 after the signal channel is formed. Thereafter, the first subscriber communication device 10 transmits and receives data through a traffic channel newly generated by the terminal matching device 20.

In this way, the terminal matching device 20 outputs a service response signal for one service request and processes the service request signal of the other pressurized paper waiting at step 220. In this case, the terminal matching device 20 performs a signal processing procedure in the same process as that for establishing a traffic channel of the first subscriber communication device 10 in order to set the traffic channel of the second subscriber communication device 12. You have to go through. That is, the above-described steps (202) and (208) to (216) must go through the process. However, this process is not performed through the paging channel and the signal channel as in the first subscriber communication device 10, the call connection process is carried out through the signal channel generated in the first subscriber communication device (10). That is, the channel is the same as the signal flow in the paging channel and the signal flow in the signal channel is repeated through the signal channel.

In the embodiment of FIG. 3, only two subscribers request the service at the same time. However, even when three or more subscribers simultaneously perform the service request, the service is similarly provided through the process according to the order in which the service is requested. Can provide. That is, it is possible to increase the reliability of service provision to subscribers by sequentially processing the call without rejecting the subscriber's service request.

As described above, when processing multiple calls simultaneously connected in the subscriber matching device of the wireless subscriber network, the service is sequentially performed in the order of the connection without using the multiple signal mode and rejecting the service for the simultaneous service request. As a result, it is possible to increase the reliability of service provision of subscribers.
