Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control method for easing traffic on an upper radio line (line from a mobile terminal to a radio base station) in a mobile message communication system.

Conventional two-way communication (fixed line communication and mobile communication) mainly consists of telephone calls, and once a line between subscribers is set up, the line remains on hold for a period of time until the call is terminated.

For this reason, conventional mobile communications services have attempted to reduce traffic by using multiple radio frequencies. However, in the mobile message communication system, which performs two-way communication of data or voice for several to several tens of words,
Only one or several channels of radio frequency are used.
The conventional technology has the disadvantage that many calls are lost. In the present invention, when a fixed subscriber in a mobile message communication system sends a message to a mobile subscriber, the line control station adds a response time to the message and sends it, and the mobile subscriber responds with the specified response time. The system is characterized in that a response message to the message is sent to the fixed subscriber, and its purpose is to alleviate traffic on the wireless line.

The present invention will be explained in detail below with reference to the drawings. 0 Figure 1 is a line configuration diagram of the mobile message communication system, and shows 11,
12,...ln are fixed terminals in the mobile message communication system, 2 is a line control station in the mobile message communication system, 3 is a radio base station in the mobile message communication system,
41, 42, . . . 4n5 are mobile terminals in the mobile message communication system.

The line control station 2 and the mobile terminals 41, 42, . . . 4n each have a memory. Further, 1 is mobile message information, 2 is mobile message information to which a response time has been added, 3 is a simultaneous sending command, and 4 is a response message.

FIG. 2 shows a time chart of outgoing and incoming signals between the line control station and the mobile terminal. The operation will be explained with reference to FIG. 1 and FIG. 2.

Assume now that there are n fixed terminals that have transmitted mobile messages, as shown in FIG. First, fixed terminals 11 and 12
,...1n is edited by the line control station 2 by adding a response time, and sent to the mobile terminal 41.
, 42, . . . 4n. As for this response time, the line control station 2 specifies different times for each message, for example, as follows. Fixed terminals 11, 12, . . . 1 to which response times are added.

21, 22, and 2, respectively.
3, the messages in the line control station 2 can be edited so that messages that arrive within a specified time are sent out, or messages that come in are sent out all at once when they reach a specified number. and accumulate messages for a while.

The mobile terminal receives this message, and when attempting to send back a response message, inputs the response message into the mobile terminal, stores it in the memory within the mobile terminal, and then sends it from the line control station 2. Waiting for simultaneous transmission command.

At a certain time TOvc, the mobile terminal 4 at the line control station 2
Issue a simultaneous transmission command to 1, 42, ... 4n. The mobile terminals 41, 42, . . . 4 that received this. So, that time T. A response message is automatically sent to the fixed terminal at the time when the previously specified response time has elapsed. When this message reaches the line control station 2, it can be determined from the difference in response time which mobile terminal the response came from, and the response message is sent to the corresponding fixed terminal. Also, mobile terminals 41, 42, . . . 4. Now, if you don't want to send the response message back, don't input anything to the terminal; in this case, design the terminal device so that it doesn't send anything even if a command to send all at once is sent. . This results in
Since no data is sent during the response time of the terminal, the line control station 2 determines that there is no response message.
It is assumed that the radio base station and mobile terminal radio equipment are always in a receiving state and are in a transmitting state only when transmitting a message. As explained above, the mobile message control system of the present invention shifts the time at which a mobile terminal sends back a response message, so even if the number of radio frequencies used in the mobile message communication system is one, call loss due to collision of response messages can be avoided. This has the advantage that the traffic of the V1 upstream radio circuit is improved.

Claims (1)

[Claims] 1 In a mobile message communication system that transmits short text or voice messages and responds to them between fixed terminals that are subscribers of a fixed communication network and mobile terminals, and between mobile terminals, a message is sent from a fixed terminal. When doing so, a line control station installed between the fixed terminal and the wireless base station adds a response time representing the interval from receiving the paging command to sending the message to the message and sends it to the mobile terminal. A mobile message, characterized in that the mobile terminal transmits a response message to the fixed terminal at a time when the response time has elapsed from the time when the mobile terminal received the paging command from the line control station. control method.
