The present invention relates to a wireless call system, and more particularly to a control method for improving the wireless call call processing capability.

Figure 1 shows a block diagram of a typical radio calling system. The radio calling system 100 is connected to a public switching telephone network (PSTN) 200. The radio calling system 100 comprises a switch 15 consisting of a relay line junction 2 and a number translation processor (NTP) 2, and a paging station 20 to the switch 15 for radio calling. Is connected. The radio calling station 20 includes a paging subscriber controller (PSC) 6, a paging control interface processor (PCIP) 8, and a paging control interface (PCI) 10.

In the radio calling system 100, the relay line matching unit 2 receives a relay line matching with another switch, a digit of a station number and a called number, and receives a message to be sent to the pager. NTP (4) performs the number translation function for the message of the radio pager received by the relay line matching section (2), performs the translation of the called party received by the relay line matching section (2) and the translated number to the radio call When the number is related, the PSC 6 requests an incoming call. The PSC 6 manages 16 RF channels (CHs), and there are about 1500 queues in one RF channel. Therefore, when the NTP 4 requests an incoming call, the PSC 6 sequentially stores the corresponding processing message in this queue. Then, when the PCIP 8 is in the idle state, the PSC 6 sequentially extracts the messages stored in the queue and outputs a paging request PRQ to the PCIP 8 together with the extracted messages. The PCIP 8 formats the data in a predetermined form that the PCI 10 can process the message received with the paging request PRQ and transfers the formatted data to the PCI 10.

The PCI 10 generates and applies a message to the transmitter 12 in accordance with a protocol capable of transmitting data output from the PCIP 8, that is, data formatted in a predetermined form, through the transmitter 12.

In FIG. 1, when the paging transmission message is transmitted in response to the paging request signal PRQ of the PSC 6 between the PCIP 8 and the PCI 10, only one delivery path (Outlet: OL) is configured. The memory areas of the PCI 10 for receiving the message of the PCIP 8 transmitted through the delivery path OL and transmitting it to the transmitter 12 are configured as one storage area as shown in FIG. do. That is, the memory area includes a transmission message storage area 400 and a reception message storage area 402, and a run check flag is configured to check message transmission and reception. The PCIP 8 is an upper processor of the PCIP 10, and thus one transfer path OL is composed of one buffer. Therefore, when the write message signal WMSG (Write Message) is applied to the PCI 10 by the PCIP 8, the message in the buffer is transmitted to the transmit message storage area 400 of the PCI 10 as shown in FIG. Is recorded.

The conventional protocol flow in the radio call station is performed as shown in FIG. Referring to FIG. 2, when the PSC 6 transmits a paging request signal PRQ to the PCIP 8 together with a message to be transmitted, the PCIP 8 transmits a message to the PCI 10. If idle, the message is formatted in a form that can be processed by the PCI 10, and the formatted message is transmitted to the PCI 10. The message sent from the PSC 6 to the PCIP 8 includes a message call type, an RF channel (CH) number, a hardware device number, and a pager recount count in which the pager subscriber is accommodated. , The interval of resending once when there is absolute pager repeat, the number of messages received by pager, the method of receiving message (eg tone, number, text), priority of each message, The protocol method for transmitting the pager, the pager unique number, and the content of the message received by the pager are included. In addition, the message recorded from the PCIP 8 to the PCI 10 may include a message type (test identification), a pager unique number, the number of messages received by the pager, the contents of the message received by the pager, and the like. In Figure 2 it is shown as a WMSG (Write Message) signal.

The PCIP (8) sends a busy state to the PSC (6) before sending a message to the PCI (10) when one transmission path (OL) turns out to be idle. Do not require a signal PRQ.

When the PCI 10 receives the formatted message from the PCIP 8 through one transmission path OL, the PCI 10 stores the message in the transmission message storage area 400 of FIG. 4 and then conforms to a protocol capable of transmitting the message. A message is generated and output to the transmitter 12. After that, the PCI 10 sends a completion signal (Complete: CPL) to the PCIP 8, and the PCIP 8 responding to this sends an idle signal Idle to the PSC 6. By the idle signal Idle, the PSC 6 can transmit a paging request signal PRQ for sending a message.

As described above, in the conventional wireless calling system, there is only one transmission path (OL) for transmitting a message between the PCIP 8 and the PCI 10, and accordingly, to transmit one message as shown in the protocol of FIG. The PSC 6 could send another message only after receiving the idle signal Idle after transmitting the paging request signal PRQ. For this reason, in the conventional wireless calling system, when a large amount of messages are received, the call processing capability is deteriorated because it cannot be processed quickly.

Accordingly, an object of the present invention is to provide a method for improving call processing capability in a wireless call system.

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

The configuration of the present invention is the same as that of FIG. 1, and the operation thereof is also the same. However, the present invention implements four message transfer paths (OL) between the PCIP 8 and the PCI 10. The four delivery paths OL implemented according to the present invention are not physically four but one physical delivery path. However, one physical delivery path OL is composed of four buffers in the PCIP 8 and the messages of each buffer are recorded in the transmission message storage areas of the PCI 10 at predetermined time divisions. It is achieved by two transmission paths (OL).

The memory map of the PCI 10 for storing the messages of the four transmission paths OL is configured as shown in FIG. Referring to FIG. 5, four transmission message storage areas 500 are configured to store messages transmitted from the PCIP 8. The transmission message storage area 500 also includes a test transmission message storage area. The reception message storage area 502 is configured as one as in the conventional reception message storage area (402 of FIG. 4). In the memory map, four transmission flags and a test transmission flag 500 are configured to display idle and busy of four transmission message storage areas (including a test transmission message storage area) 500. do.

3 is a diagram illustrating a call processing control protocol for improving wireless calling capability according to the present invention.

Referring now to FIG. 3, when the PSC 6 transmits a paging request signal PRQ to the PCIP 8 together with a message to be paging transmitted, the PCIP 8 sends four transmission paths (a message to the PCI 10). OL #) (where # is 0-3) to see if it is idle. The PCIP (8) first assigns a predetermined delivery path (OL #) to be searched as busy status (Busy) and checks the status of the delivery path (OL #), respectively, and all the delivery paths (OL #) are busy status (Busy). In this case, the busy state Busy is transmitted to the PSC 6, and the idle state Idle is transmitted to the PSC 6 even if at least one or more transfer paths OL # are not busy.

The PCIP 8 then formats the message authorized by the PSC 6 into a form that can be processed by the PCI 10, and formats the formatted message through the transmission paths OL # retrieved in idle state. To pass).

This is represented as WMSG (Write Message) 0, 1, 2, 3 in FIG. For example, when the PCI 10 receives the first message WMSG 0 from the PCIP 8, the PCI 10 stores the first message WMSG 0 in the transmission message storage area 0 of FIG. 5. Accordingly, transmission flag 0 is set to one.

On the other hand, when the PSC 6 detects the idle state for the predetermined delivery path (OL #) from the PCIP 8, it delivers the message in the next queue to the PCIP 8, and at the same time, another predetermined delivery from the PCIP 8 When the idle state is detected for the passage OL #, the message on the next queue is continuously delivered to the PCIP 8. At this time, the PCIP 8 can know how many messages are in the queue of the PSC 6 because the received message includes information such as the number of messages received by the pager and the priority of each message.

Accordingly, the PCIP 8 stores each of the other messages received from the PSC 6 into four buffers provided with each other, formats the data to be processed by the PCI 10, and delivers the formatted messages to the PCI 10. Give it. Accordingly, the PCI 10 stores different messages in the transmission message storage areas 500 shown in FIG. 5 by recording control of the PCIP 8, which is an upper processor, and stores corresponding transmission flags 504. Set to.

Thereafter, the PCI 10 reads each message in the transmission message storage areas 500, generates a message corresponding to a protocol capable of transmitting the message, and outputs the message to the transmitter 12. After that, the PCI 10 sends a completion signal CPL to the PCIP 8 and the PCIP 8 responding to this sends an idle signal Idle to the PSC 6. By the idle signal Idle, the PSC 6 can transmit a paging request signal PRQ for sending a message.

As described above, the present invention has a merit that four transmission paths (OL) between the PCIP (8) and the PCI (10) can be processed a lot of transmission data for the wireless call, so that the wireless call call processing capability is improved. have.
