Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data transmission / reception system of a mobile communication system for controlling transmission / reception of information data between a radio base station and a mobile device in the mobile communication system.

[0002]

2. Description of the Related Art FIG. 3 is a block diagram showing an example of an information data transmission / reception system of a conventional mobile communication system.

Referring to FIG. 3, in the mobile communication system of the conventional example, an external host device 1 for creating information data to be transmitted to the mobile device 6, and an information data input for receiving the information data from the external host device 1. The device 21 includes an information data stock section 7 for storing information data, a transmitting device 42 for transmitting information data to the mobile device 6, and a receiving device 52 for receiving response information data from the mobile device 6. It

Then, the information data stock section 7 connects the writing means 71 for writing the information data from the information data input device 21 and the transmission address pointer indicating the transmission address of the information data to be transmitted to the transmission information data and receives it. The address pointer acquisition unit 72 searches the response information data received by the device 52 for corresponding information data in the pool buffer.

Next, the operation of the conventional example will be described with reference to FIG.

FIG. 4 is a flow chart for explaining the operation in FIG. 3, (a) shows the main flow of the information data transmission / reception processing, and (b) and (c) show the information data transmission subroutine in FIG. And a flow of an information data reception subroutine are shown respectively.

First, the information data input device 21 checks whether or not there is transmission information data provided from the external host device 1 (step S41). If there is transmission information data (Y in S41), the information data transmission subroutine is called and the flow of FIG. 4B is executed (S42).

That is, the information data stocking unit 7 checks whether or not there is an unused portion of the pool buffer, and if there is an unused portion (Y in S421), the writing means 71 writes information to the end of the pool buffer currently stored. Store data (S
422). Next, the address pointer acquisition means 72 connects the transmission address pointer indicating the transmission address of the information data to be currently transmitted to the transmission information data (S423). Then, the transmission device 42 transmits the information data to the mobile device 6 (S424).

When the mobile device 6 receives the information data from the transmitter 42, it returns a response corresponding to the content of the information data and changes the internal state. After S424 or when the answer is N in S421, the information data transmission subroutine is terminated and the process proceeds to S43. It should be noted that the process proceeds to S43 even if there is no transmission information data in S41, that is, N.

In step S43, the receiving device 52 checks whether there is response information data received from the mobile device 6. And S43
If Y, that is, if there is response information data, the information data receiving subroutine is called and the flow of FIG. 4C is executed (S44).

That is, the receiving device 52 fetches the response information data from the mobile device 6 (S441). The address pointer acquisition means 72 searches this response information data to check whether or not there is a corresponding information data portion in the pool buffer (S442). If there is a relevant information data part here (S
In 442, Y) The transmission information data is released (S44).
3), the pool buffer part is made unused (S44)
4).

In S442, that is, when N, that is, when there is no corresponding information data portion in the pool buffer or after S444, the information data receiving subroutine is ended and the process proceeds to S45. It should be noted that the process proceeds to S45 even if N is obtained in S43, that is, if there is no response information data received from the mobile device 6.

In S45, when the transmission address pointer is other than "0" (N in S45), it is judged that the transmission is incomplete, and the process returns to S41. When the transmission address pointer is "0" (Y in S45), transmission is performed. The operation is judged to be completed and the operation ends.

In the conventional method of storing this kind of information data in the pool buffer, the storage location of the information data is fixedly allocated on the pool buffer.

Next, as another example of the conventional data transmission / reception system, there is a "memory information dump system" described in Japanese Patent Laid-Open No. 4-357536.

FIG. 5 is a block diagram of a memory information dump system showing another example of the conventional data transmission / reception system, and FIG. 6 is a diagram showing a configuration example of the memory area information in FIG.

The conventional memory information dump system is composed of a host device 81 and a peripheral controller 82.

Then, the peripheral controller 82 manages the readable / writable storage area 83 by logically dividing it into areas A, B, C and D as shown in FIG. Identification information having a logical meaning is added to each of the areas A, B, C and D, and memory area information 84 composed of the identification information, the start address and the memory capacity is created as shown in FIG. The memory area information 84 is held in the memory 83, and the memory area information 84 is transferred to the host device 81 according to the designation from the host device 81.

Further, since the host device 81 first holds the memory area information 84 output from the peripheral controller 82 and dumps the memory contents that change from moment to moment when necessary, the memory area held is retained. The identification information in the information is searched, the memory area dump command 85 accompanied by the searched identification information and the start address is output, and the peripheral control device 82 receiving the memory area dump command 85 returns it as a response. The storage area information 86 is received.

In this conventional example, by adopting such a configuration, when the memory dump of the peripheral device is performed, the maintenance person can dump the target memory area only by specifying the identification information, and the maintenance work is improved. . However, this conventional example is completely different from the present invention in all of its objects, configurations, operations and effects.

[0021]

In the above-mentioned conventional method of transmitting / receiving information data of the mobile communication system, this information data has a fixed address on the pool buffer when storing and managing the information data. Therefore, there is a problem in that the search when performing the transmission process becomes complicated and takes time.

Further, there is a problem that it is difficult to edit the transmission address of the information data, and thus it is difficult to retransmit.

Further, since the usage state of the memory area on the pool buffer is not managed, there is a problem that the memory is not effectively used.

It is an object of the present invention to provide a data transmission / reception system for a mobile communication system that facilitates data transmission / reception processing to shorten the time and enables effective use of memory.

And a flow of an information data reception subroutine are shown respectively.

First, the information data input device 21 checks whether or not there is transmission information data given from the external host device 1 (step S21). If there is transmission information data (Y in S21), the information data transmission subroutine is called and the flow of FIG. 2B is executed (S22).

In other words, the storage location search determining means 22 uses the 1-bit assigned to each of the pool buffers divided into 16-byte units to create a bitmap area that represents a used portion or an unused portion of the buffer. It is checked to see if there is an unused portion (S2
21).

If there is an unused portion (Y in S221), the writing procedure means 31 stores 16 pieces of information data to be stored.
When it is necessary to use a plurality of pool buffers divided into byte units, the pool buffer is divided into minimum units (S22
2) The information data is stored in the unused part of the pool buffer (S223). Then, the location of the stored pool buffer is set as the used portion (S224).

Next, in the ring buffer processing means 32,
A transmission address is added to the stored information data (S22
5) Concatenate the transmission addresses and operate which transmission address the transmission address pointer refers to for transmission (S)
226).

In the mobile unit transmission unit 4, the transmission address pointer acquisition unit 41 recognizes the storage location of the information data from the transmission address pointer to be currently transmitted indicated by the ring buffer processing unit 32 (S227), and then the transmission unit 42 is notified. When the information data is passed, the transmission device 42 transmits this information data to the mobile device 6 (S228).

When the mobile device 6 receives the information data from the transmitter 42, it returns a response according to the content of the information data and changes the internal state. After S228 or when the answer is N in S221, the information data transmission subroutine is terminated and the process proceeds to S23. It should be noted that the process proceeds to S23 even if S21 is N, that is, there is no transmission information data.

In S23, the receiving device 52 checks the presence or absence of the response information data received from the mobile device 6. And S23
If Y, that is, if there is response information data, the information data receiving subroutine is called and the flow of FIG. 2C is executed (S24).

That is, the receiving device 52 fetches the response information data from the mobile device 6 (S241). The transmission address pointer releasing means 51 searches this response information data to check whether or not there is a corresponding information data portion in the pool buffer (S242). If there is the corresponding information data portion (Y in S242), the stored information data is released (S243) and the added transmission address is released (S424). Then, the transmission addresses are concatenated and the transmission address pointer is operated (S245), and the area stored in the pool buffer is set as an unused portion (S246).

If N in S242, that is, if there is no corresponding information data portion in the pool buffer or after S246,
The information data receiving subroutine is ended and the process proceeds to S25.
It should be noted that the process proceeds to S25 even if the answer is N in S23, that is, if there is no response information data received from the mobile device 6.

In S25, when the transmission address pointer is other than "0" (N in S25), it is judged that the transmission is incomplete, and the process returns to S21. When the transmission address pointer is "0" (Y in S25), transmission is performed. The operation is judged to be completed and the operation ends.
