Therefore, when accommodating small subscribers distributed in a specific area is not enough utilization of the resources of the base station controller 13, there is a need for a base station apparatus that can solve this disadvantage.

The conventional wireless subscriber network system currently being developed in Korea is composed of a plurality of subscriber stations (subscriber access devices), a base station for connecting them wirelessly, a base station controller for controlling several base stations and connected to a switch. The wireless subscriber network system having such a configuration has no problem when accommodating a large number of subscribers, but when the wired subscriber line is well established as in Korea, the demand for the wireless subscriber network is distributed in a region where a relatively small number of subscribers is limited. It is likely that you will be concentrated where you are. If the conventional wireless subscriber network system is installed in such an area, only a part of the capacity of the base station controller is used, thereby operating the system inefficiently.

In general, the base station controller is configured to control and manage 16 base stations, in which case one base station controller can accommodate up to 8,000 subscribers. However, considering the facilities and distribution of domestic wired subscriber lines, it is unlikely that many subscribers will be accommodated in the wireless subscriber network (WLL) at the same time, making it difficult to properly use the capacity of the base station controller. . Therefore, if the conventional system structure is maintained as it is, the cost of the wireless subscriber network is increased, which causes a problem of lowering the investment efficiency and weakening the competitiveness with other subscriber networks.

4A and 4B are flowcharts of an embodiment of a method of operating an integrated base station according to the present invention.

As shown in FIGS. 4A and 4B, when a call request is generated through the access channel, the base station receives the access channel message to the processor 1 39 through the RF unit 31 and the wireless modem unit 32 (401). .

Subsequently, when processor 1 39 receives the access channel message and proceeds interprocessor communication to request outgoing call processing to processor 5 43, processor 5 43 analyzes the outgoing call processing request message (402). In step 403, the type of traffic information is determined.

As a result of the determination (403), if the voice traffic is requested to the processor 2 (40) voice conversion processing (404), the processor 3 (41) requests the switch channel allocation (406), if the data traffic processor 2 (40) After requesting the non-conversion processing from the user (405), the processor 3 (41) requests the switch channel allocation (406).

Subsequently, the processor 3 (41), which has been requested to allocate the channel, selects the exchange matching E1 or the data network matching E1 according to the traffic information type in the switch channel allocation request message to allocate the channel (407). At this time, when processor 5 (43) requests processor 4 (42) to transmit to the switch (38) (408), processor 4 (42) passes to the switch (38) through the V5.2 protocol message transmission / reception channel. The V5.2 message is transmitted, and the response of the switch 38 is received, and the processor 5 43 is notified of the channel allocation request (409). Accordingly, the processor 5 (43) notified of the channel allocation request requests the processor 1 (39) to allocate a radio channel (410).

Subsequently, processor 1 39 forms a paging message, requests channel allocation to the terminal station through the paging channel, allocates a channel, and determines the type of traffic information (411).

As a result of the determination (411), if the voice traffic receives a dial tone from the exchange and then makes a call with the other party through dialing (412), if the data traffic is connected to the data network through the data network matching device (IWF: InterWorking Function) (413).

On the other hand, if the traffic type is traffic by analog modem or G3 fax (FAX), the call is initially set up in the same process as the voice traffic described above, and then the fax or modem tone is detected by the transcoder unit 33. In this case, the call being set up is transmitted to the processor 5 (43) through the processor 2 (40), rather than the voice call. Processor 5 43 requests channel change from voice channel to voice band data channel through signal channel in the corresponding traffic channel through processor 1 39. The terminal station receiving the channel change request changes the channel and transmits the change completion message to the processor 1 39 via the RF unit 31 and the wireless modem unit 32. Upon receiving the channel change completion message from the terminal station, processor 1 39 transmits the channel change completion result to processor 5 43. Processor 5 (43) receives this request to the processor 2 (40) to perform a non-transformation processing, the processor 2 (40) is a non-transformation processing, so all the path from the terminal station to the exchange 38 is composed of a channel of 64kbps You can use a fax or modem.
As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, ROM, RAM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. Since this process can be easily implemented by those skilled in the art will not be described in more detail.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

As described above, the present invention includes the functions of the base station controller in the base station without installing the base station controller in the switching center by using the integrated base station. The need for manpower is eliminated. In addition, the wired subscriber network is well established as in Korea, so if the demand of the wireless subscriber network (WLL) is small or limited in some regions, the system can be efficiently used to improve economic efficiency.
