Abstract

PURPOSE:To easily process lots of message and calls by dividing a message to be sent to a pager and sending the divided messages. CONSTITUTION:When the length of a message to be sent exceeds a length of one frame (FRM) #2, an identifier ID2 representing the presence of a connection frame is added to a head (or tail end) of a message area (MA) 10 in the FRM#2 of a batch (BCH) 11, the pager message is divided into a length of the FRM#2 and the divided messages are sent one after another. That is, when the pager message has a length set in the FRM#2 of BCHs 11,12, an identifier IC1 representing absence of a succeeding frame is added to the head or the tail end of the MA10 of the FRM#2 of the BCH 12 and the resulting frame is sent. Moreover, the pager message to be sent is divided into the length of two or over of optional frames and the KID1 is added to a head or a tail end of the MA 23 and the resulting frame is sent.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pager message division transmission system in a paging system.

[0002]

2. Description of the Related Art FIG. 2 is a diagram showing an example of a signal format of a transmitted pager message in a conventional pager message transmission system. The position of the frame for one call is fixedly assigned like frame # 2 of batch (hereinafter BCH) 31 composed of eight frames (hereinafter FRM # 1 to # 8), and an attempt is made to transmit. When the message length exceeds the length of one frame previously assigned to the call, the message is interrupted and transmitted to the FRM # 3 adjacent to FRM # 2 like the message area (hereinafter MA) 30 of the BCH 32 and transmitted. It was like this. Further, when the message cannot be filled in one BCH 32, it interrupts the next adjacent BCH 33 and transmits it. In FIG. 2, SC indicates a sync code word and PA indicates a pager address.

[0003]

In this conventional message transmission method, the longer the message length to be transmitted in one call, the more frames are monopolized, and the other call is accepted. There is a possibility that it may not be possible to do so.

[0004]

According to the pager message division / transmission method of the present invention, when the length of the pager message to be transmitted to the pager exceeds the length of one frame assigned to the call, the pager message division is arbitrarily performed. It has a transmission control means for varying the length of the transmission.

Then, the transmission control means divides the pager message and uses a plurality of frames of the same number in different batches, and adds a first identifier indicating that there is no continuous frame in the message area to the last frame. In addition, a second identifier indicating that there is a continuous frame is added to the message area other than the last frame and transmitted, or the pager message is divided and adjacent empty frames of the same batch are used. , The first identifier indicating that there is no continuous frame is added to the last frame and transmitted.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIGS. 1A and 1B are diagrams showing the signal format of a transmission pager message in the first and second embodiments of the pager message division transmission method of the present invention.

Next, the operation of this embodiment will be described. As shown in FIG. 1A, when the message length to be transmitted exceeds the length of one FRM # 2, the transmission control unit of the first embodiment performs MA in FRM # 2 of BCH11.
An identifier (hereinafter referred to as ID2) indicating that there is a continuous frame is added to the head portion (or the tail portion) of 10, and the pager message is divided into the lengths of FRM # 2 and transmitted one after another. Therefore, the pager message is BCH11 and BCH12.
If the length is within the FRM # 2 of BCH12,
An identifier (hereinafter referred to as ID1) indicating that there is no continuous frame is added to the head or tail of the # 10 MA 10 and transmitted.

As shown in FIG. 1B, the transmission control unit of the second embodiment has an adjacent FRM # 3 of FRM # 2 of BCH21.
If the subsequent pages are not used by another call and are empty, or if you want to send a pager message that exceeds the length of two frames at a time, send the pager message that you want to send with a length of two or more arbitrary frames. And the ID1 is added to the beginning or the end of the MA 23 as in the first embodiment.
Is added and transmitted.

[0009]

As described above, according to the present invention, an identifier is added to the foremost part or the last part of a message area in a frame so that a message of an arbitrary length can be transmitted without affecting other calls. It has the effect of being able to.
