Abstract

A portable or vehicle radio of a two-way radio system for use by a group is generally in direct call mode as a generic radio. Once a communication range is needed to be expanded under a condition of no available repeater, a group commander is able to designate a two-way radio most suitable for functioning as a signal repeater according to GPS location through over-the-air programming or manual control to expand the communication range. The signal repeater retransmits signals being received through time division multiple access (TDMA) over a same channel at different time slots that provides a function of expanding a communication range as a conventional dual-band repeater transmitting signals over uplink and downlink bands does. Therefore, the two-way radio of the two-way radio system functions as a generic radio as well as a signal repeater for transmitting through TDMA at different time slots, so as to become a mobile disposal system for providing temporary, emergent and expanded communication range when an emergency is occurred.

Description

Mobile dispatch system that expands communication range with two-way walkie-talkie

This author is a mobile dispatch system that uses a two-way walkie-talkie to expand the communication range, especially a group two-way walkie-talkie system in the absence of a repeater (station) or repeater damage, when the group performs tasks When it is necessary to move the location and expand the communication range of the group, at least one of the most suitable two-way walkie-talkies (including portable or vehicle-mounted walkie-talkies) in the group can be selected manually or by radio according to the global positioning system (GPS) coordinate position. The over-the-air programming (OTAP) operation reset setting is used as a signal repeater, enabling the group to easily establish a system and method for providing a temporary emergency extended communication range.

For groups that are generally performing duties (police, medical, military, and emergency relief teams, etc.), when performing duties in areas where there is no fixed signal relay station or signal relay station damage, for example, in the wilderness area in the mountains, or In areas where damage to communications infrastructure is caused by earthquakes, typhoons, floods, landslides, or when performing combat missions, the group's 2-way radios use one-to-one or a pair of direct calls in such areas. A lot of regional instant messaging functions; in addition, if you know in advance that a large communication range is required in the area where the service is performed (including the situation where the relay station that knows the disaster site is damaged due to a disaster), the traditional double will be carried and set in advance. Frequency repeaters to extend the communication distance of the group; however, most emergency disaster events (such as the various emergencies mentioned above) occur unpredictably and require service The required communication range is also unpredictable, which causes the commander to be unable to grasp the scene of the disaster site in an instant due to insufficient communication distance during the disaster, and cannot effectively command and dispatch the personnel and equipments involved in the rescue, thus losing the best rescue opportunity. Make the disaster worse.

Under the above circumstances, the conventional group two-way walkie-talkie system cannot solve the problem of temporarily expanding the communication range, because the conventional two-way walkie-talkie (100 and 200) usually uses a radio-to-radio direct call (Direct call, Direct talk). The mode of communication (as shown in Figure 1), the communication distance is limited to the communication range (101) with radius R1; when the two-way intercom (200) in the group moves beyond the two-way intercom (100) Direct call communication range (101), then need to use traditional dual-band repeater or relay station (300) to divide by frequency multiplex access (FDMA, Rx F1 and Tx F2) The method performs signal forwarding, so that the communication range (101) which is originally limited to the radius of R1 can be extended by the communication range (301) of the dual-frequency repeater (300) with the radius of R2 to extend the communication of the group. Distance (as indicated by the slash area in the illustration).

However, the above-mentioned conventional dual-frequency repeater (300) includes both fixed and portable types, wherein the fixed device is easily damaged by the occurrence of a disaster event; the portable device is prone to carry the number of carriers Insufficient or simply forgotten to carry, resulting in a situation that is prone to the actual use of the situation, or other inconvenience in use.

In addition, the conventional dual-frequency repeater (300) needs to have a duplexer (Duplexer) device, so it is large and heavy in weight and weight, and is not suitable for carrying (generally a vehicle-mounted repeater); And the traditional repeater is not only inconvenient to carry, but its setting position is also very considerate, especially in the case of frequent changes in the position of the service execution.

Moreover, another problem with the conventional repeater (300) is that it requires two frequencies, both of which require special assignments, in order to avoid interference with each other on the field. Line specifications, so the upper/lower chain frequencies are required to have their minimum frequency spacing, so the two frequencies that apply for the repeater must wait and pay more for the frequency.

The creator of the present invention considers that it is necessary to provide a new group two-way walkie-talkie system in view of the above-mentioned problems that the conventional two-way walkie-talkie system uses a dual-frequency repeater to extend the communication distance of the group. The two-way walkie-talkie communicates with other two-way walkie-talkies in a direct call. Once the communication range needs to be expanded, the commander or user can select the most suitable two-way walkie-talkie based on the location of the group personnel. And reset the signal repeater that can provide the signal forwarding function through the OTAP command or manual operation, making the group a mobile dispatch system capable of providing temporary emergency expansion communication range.

The main purpose of this creation is to provide a group two-way walkie-talkie system in the absence of or the repeater is damaged, because the scope of its service is too wide, the commander or user can not communicate when the walkie-talkie is unable to communicate by Direct call. According to the location of each two-way walkie-talkie in the group (or the relative position of the group move), select one suitable two-way walkie-talkie among several portable or vehicle-mounted walkie-talkies, and manually or OTAP-instruction It is reset to a signal repeater (single-frequency time-division multiplex access mode) to support the method of the group two-way walkie-talkie system for temporarily expanding the communication range.

The second purpose of this creation is to provide a group two-way walkie-talkie system. When the scope of its execution service needs to continue to expand, the first two-way walkie-talkie is designated as a signal repeater. The relay signal coverage cannot meet the execution service. When the distance is extended, the commander can again designate or notify another two-way walkie-talkie in the appropriate position as the second repeater, so that the communication distance extends to the two-way distance of the two-way walkie-talkie system in the direct call mode.

The mobile dispatching system which expands the communication range by using the two-way walkie-talkie described in the present invention performs the service for the group using the two-way walkie-talkie in the environment where there is no relay station or the relay station is damaged, and needs to constantly change the position (such as disaster relief), and one However, when the emergency needs to expand the coverage of the communication, the commander of the team can select one of the most in the distribution of the position of each member on the display screen of the two-way walkie-talkie used by the Global Positioning System (GPS). A two-way walkie-talkie suitable for the relay position, and then the designated two-way walkie-talkie is switched from the direct call mode to the single-frequency forward mode by manual or radio command (OTAP) control to be used as a signal repeater, and changed to time-multiplexed The access (TDMA) method forwards signals in different time slots on the same channel, thereby providing the communication range required by the two-way walkie-talkie in the group to perform the service to expand the moving distance.

As described above, the designated signal repeater then sends a notification or OTAP command to all other two-way walkie-talkies using the same channel in an all-call manner, requiring them to switch to the single-frequency forwarding mode and switch to the TDMA protocol. Communicating; receiving another two-way intercom that is notified by TDMA communication, by manually or automatically converting the in-use direct call mode into a single-frequency forwarding mode for communication; and the other two-way intercom is converting to single-frequency forwarding After the mode, an acknowledgement (Ack) message is automatically sent to the signal repeater or/and the two-way walkie-talkie used by the commander.

Accordingly, the system and method of the present invention can select one or more two-way walkie-talkies in a group to be used as a signal repeater to provide a dual-frequency repeater (used/down) that is commonly used with existing ones. Chain frequency) The same function of expanding the communication range, without relying on the existing dual-frequency repeater, to achieve a mobile dispatch system with reduced equipment and temporary emergency needs to expand the coverage of the communication, and also does not need to apply again The advantage of the two pairing frequencies of the relay.

Please refer to FIG. 2, a mobile dispatch system using the two-way walkie-talkie to expand the communication range, and perform the service for the group using the two-way walkie-talkie in the environment without the relay station or the relay station being damaged, and need constant Replacing the location, and once the emergency needs to expand the coverage of the communication, where: a. The group's commander's position according to the position of each group member displayed on the display screen of the two-way intercom (GPS) used by the Global Positioning System (GPS) Situation, from which at least one two-way walkie-talkie (including a portable or vehicle-mounted walkie-talkie) that is most suitable for the relay position is selected; b. via the commander, the selected two-way walkie-talkie in the most appropriate position is operated by manual or OTAP command, Switch from Direct talk around mode to One channel repeater mode as a signal repeater, in the same way as Time Division Multiple Access (TDMA) The channel forwards the signal in different time slots; c. the designated signal repeater then sends a call in the whole call mode OTAP instructions to all known or used two-way radio of the same channel, which requires conversion to a single-channel repeater mode, TDMA changed to the communication protocol; d. receiving a two-way walkie-talkie from the signal repeater and changing the TDMA communication notification, and manually or automatically converting the in-use direct call mode into a single-frequency forwarding mode to communicate with other two-way intercoms; e. the two-way walkie-talkie After switching to the single-frequency forwarding mode, an acknowledgement (Ack) message is automatically sent to the signal repeater or/and the commander's two-way walkie-talkie (including a portable, vehicle-mounted walkie-talkie or console).

As mentioned above, please refer to FIG. 3 again, when the group of the two-way walkie-talkie system (1) performs the service in a non-relay environment, if the distance of the two-way walkie-talkie within the group exceeds the direct call (Direct call) The communication distance can be converted into a signal repeater (30) by the bi-directional intercom (10) of the ethnic commander by using the OTAP command to designate a two-way walkie-talkie in a suitable position in the two-way walkie-talkie (20); The signal repeater (30) is within the direct communication range (11) of the commander (two-way walkie-talkie 10) and is optimally located farthest from the commander, according to which the two-way walkie-talkie (10) and the two-way walkie-talkie ( 20) The communication range between the signal repeater (30) and the communication range (31) of the signal repeater (30) can be extended to extend the communication distance of the group.

According to the above system and method, when the two-way walkie-talkie designated as the signal repeater (30), a notification or OTAP command is sent in the ALL Call mode to all the two-way walkie-talkies (10 and 20) using the same channel, The subsequent communication is switched to the single-frequency forwarding mode and the TDMA communication protocol is used for ethnic communication; wherein the signal repeater (30) can be placed on-site at the time of implementation or carried by the group member. The mobile change position; and, can be designed to automatically switch to the single-frequency forwarding mode after three consecutive notifications of the converted communication mode, or to receive at least the Ack information of the other two-way walkie-talkie (20) before switching to the single The frequency forwarding mode works.

As described above, when any two-way walkie-talkie (20) in the group receives the notification from the signal repeater (30), the TDMA protocol is changed according to the OTAP command or the user manually switches to the single-frequency forwarding mode. Communication is performed, and an acknowledgement (Ack) message is automatically sent to the signal repeater (30) or/and the commander (bidirectional walkie-talkie 10) so that the signal repeater (30) can be automatically switched to after receiving the Ack. The single-frequency forwarding mode communicates and allows the commander to know how many members have not been notified so that the commander can then individually notify them in other ways.

As described above, in the process of using the appropriate two-way walkie-talkie to be converted into a signal repeater (30), the commander can use the two-way walkie-talkie (10) to display the walkie-talkie based on the built-in radio. The position display function can be seen from the positioning display in the display screen (find) that the position of the two-way walkie-talkie is most suitable for use as a signal repeater (30); the commander can also monitor the display in both directions at any time. The position of all the members on the display screen of the walkie-talkie (10) enables the commanding function to notify a suitable two-way intercom (20) to specify a new one by manual or OTAP command according to the change of the displayed communication range or group member movement. The signal in the machine, including the designation of changing the existing signal repeater or the new signal repeater; and the two-way walkie-talkie that has been used as the signal repeater (30), which is in the no-call (ie, does not forward At the time of the work, the user can also perform a voice call operation to perform voice communication intercommunication function for all group members (two-way walkie-talkies 10, 20) of the group.

The system and method as described above, wherein the signal repeater (30) performs a signal forwarding communication service between the plurality of two-way walkie-talkies (10 and 20), and the receiving channel includes at least an Rx time slot in a TDMA format. a, and the transmission channel used by it is the Tx time slot b.

As described above, the receiving channel in which the plurality of two-way intercoms (10 and 20) switched to the single-frequency forwarding mode communicate at least includes the Rx time slot a to the time slot b in the TDMA format. One, and the transmission channel used is the Tx time slot a.

As described above, when the other two-way intercom (20) is notified by the OTAP command to switch to the single-frequency forwarding mode, the bidirectional intercom (20) may be directly changed according to the OTAP command sent by the signal repeater (30). The Rx time slot b corresponding to the Tx time slot b of the signal repeater (30) receives the channel for communication.

In the above embodiment, when any two-way radio (20) fails to receive the correction signal (such as Dummy signal or other similar signal) sent by the signal repeater (30) within a predetermined time, the two-way intercom (20) is now out of communication coverage of the signal repeater (30); subsequently, the two-way radio (20) is issued immediately upon confirmation of the communication coverage (31) of the signal repeater (30) An alert or/and a flashing alert signal alert the user; wherein the predetermined time for the correction signal to fail to receive the signal repeater (30) is set by pulse per second (PPS).

As described above, when the signal repeater (30) is left in the field for use, and at the end of the task or when a change position is required, any of the two-way walkie-talkie (10 or 20) can further issue an instruction through the OTAP requesting the The signal repeater (30) replies to the GPS information at its location to facilitate the team member to retrieve or move the signal repeater (30).
