JPH08336176A - Pager receiver with specified selective group call function - Google Patents

Abstract

PURPOSE: To effectively use radio waves by making it possible to call a specified group member by the multi-address call at one time by setting a new multi- address index number and the table of the group number within a data memory in a pager receiver with selection function. CONSTITUTION: A pager receiver with selection function is composed of a reception part 1, a decoder 2, a data memory 3, a control part 4, a basic control program 5, a RAM 6, a notification part 7, a display part 8 and an input operation part 9. The reception part 1 receives a message signal including a group call signal, demodulates the signal and outputs the signal to the decoder 2. The decoder 2 compares the selective call signal and the call signal specific to the receiver and estimates that the specified group call exists in the case of the mismatch. The multi-address index number of the memory 3 and the contents of the selective call signal are compared. When the decision matches, it is judged to be a simultaneous call. Further, the group number within the table of the memory 3 and the received group call number are compared. When they match, the control part 4 is started.

Description

Detailed Description of the Invention

[Industrial field of use] The present invention is for calling a group member to a pager user. The target of the broadcast index number is a specified index code such as notification to information retrieval, commercial notification, various guidance, notification to group call (group conference call), etc. An arbitrary group member number belonging to the genre of the broadcast index number is shown. The telecommunications carrier defines the genre of the broadcast index number and provides the group numbering within the designated genre. As an example of this application, the group member of the pager who received the call is automatically connected to the group conference call by transmitting the group number displayed on the display unit to the communication center.

[Prior Art] A conventional radio selective calling signal receiver has a group table for registering a group member in a paging device, and when a caller makes a group call, a group is called by the paging device. In order to call the group members from the individual numbers in the table, the page numbers unique to the pager receiver were sequentially sent out.

[Problems to be Solved by the Invention] In a conventional group call, in a paging device,
It has a group table, and when a group call is requested, the individual telephone numbers of the group members in the table are used to call each member in turn, so that the group call is made by the storage device in the paging device, the central control unit, etc. The new control means is required, and the paging processing capacity is burdened by that amount, and the effective use of radio waves is not achieved.

[Means for Solving the Problems] The pager receiver with a specific group call selection function of the present invention is
In order to achieve the above-mentioned object, by comparing and matching the received selective call signal with its own selective call number,
Ordinary pager receiver individual call is judged, and if there is no comparison, it is judged that there is a call of a specific group by broadcast, and comparison is made with the broadcast index number stored in advance in the data memory of the receiver. I do. Also in this case, if the comparison does not match, it is determined that the call is not applicable, and the process ends. If the comparison matches, it is determined that a group member simultaneous ringing has occurred, and the group ringing signal in the received message signal is detected,
The group number stored in advance in the data memory of the receiver is compared. If the comparison results in a match, it is determined that the pager receiver is a target for simultaneous paging of group members, and the control unit is activated. In this way, the control unit operates the notification unit, and at the same time, the broadcast index number received on the display unit,
The group number and message contents are displayed. on the other hand,
The user can operate the input operation unit to store the broadcast index number and the group number in the RAM in the pager receiver. It is possible to freely select the broadcast index number and the group number stored in the RAM according to the purpose of use of the user and edit and set them in the data memory accessed by the decoder section.

[Operation] The broadcast index number set by the user in the data memory in the pager receiver of the present invention is a broadcast type code, that is, a genre, for making a notification or calling to a specific group member. This means information retrieval, commercial reporting group call, etc. In associating the actual ID code with the broadcast index number, a new subscription is registered to a pager telecommunications carrier in the pager service area and newly assigned I
The D code (selective calling number) is designated for that purpose, and the user is informed as the broadcast index number. On the other hand, the caller makes a numbering request to the center to receive a group number in order to arbitrarily determine a group number common to the group members who receive the call. To receive a group call,
The group number is stored and set in the group number table belonging to the arbitrarily selected broadcast index number in the data memory of the receiver. The caller may input the broadcast index number as the call ID code and the group number as the message content from the PB push-button telephone.

[Embodiment] The present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram of a pager receiver with a specific group call selection function according to an embodiment of the present invention. In the figure, 1 is a receiving unit, 2 is a decoder unit, 3 is a data memory, 4 is a control unit, 5 is a basic control program, 6 is a RAM, 7 is a notification unit, 8 is a display unit, 9 is an input operation unit. is there.

The receiving unit 1 receives a message signal including a selective call signal by a radio signal from a base station and a group call signal following the selective call signal. The receiving unit 1 receives the modulated carrier wave, demodulates it, and outputs it to the decoder unit 2. The decoder unit 2 compares the selective call signal 10 received by the radio signal with the call number 11 peculiar to the receiver, and when there is no match, the broadcast information in the frame information including the selective call signal 10 received by the radio signal is received. By detecting the identification code, the decoder unit 2 presumes that a specific group call, not a call to the individual pager, is occurring. The broadcast index number 12 previously stored and set in the data memory 3 of the receiver and the received selective call signal 10
If the contents of are matched, it is judged that the group members are all called.

Further, the contents of the group call signal in the received message signal are detected, and the corresponding broadcast index number 12 previously stored and set in the data memory 3 of the receiver.
Group number 13 in the group number table belonging to
If it matches with, the pager receiver is called as a group member. The decoder unit 2 is the control unit 4
To start. The control unit 4 operates the notification unit 7 to notify the user of the incoming call, and displays the received broadcast index number, group number and other message contents via the display unit 8.

On the other hand, the user operates the input operation unit 9 to obtain the broadcast index number and the group number in the pager receiver RAM 6
Accumulate in. The user displays the broadcast index number and the group number stored in the RAM 6 on the display unit 8 according to the purpose of use, and based on the execution of the basic control program 5, the user operates the input operation unit 9 to obtain the data. For the broadcast index number 12 in the memory 3 and the group number 13 in the table,
The data stored in the RAM 6 can be freely selected and stored.

[Effects of the Invention] As described above, according to the present invention, when calling a group member, a specific group member is called by one broadcast call without sequentially calling individual pager telephone numbers. It is an epoch-making thing that can be done, and can make effective use of radio waves.
