## Abstract

A communication system and method are provided for establishing cross-agency communications for managing an incident scene. Converged devices are paired to in-vehicle computers of public safety (PS) vehicles, each PS vehicle having a different agency role. Device capabilities are compared to determine communication commonalities amongst the paired devices of vehicles of different agency roles. One or more frequency channels common to the devices associated with the deployed vehicles of different agency roles are determined. Communication is established amongst devices associated with vehicles of different agency roles using the determined common channel.

## Claims

### Claim 1

A method of establishing cross-agency communications for managing an incident scene, comprising:
pairing a communication device with an in-vehicle computer of a vehicle, each paired communication device being a converged device;
receiving an incident notification including incident type;
determining that more than one vehicle has been deployed to the incident, each having a paired communication device;
determining agency role associated with each deployed vehicle;
determining if the number of deployed vehicles and agency role associated with each deployed vehicle are sufficient to manage the incident type using traditional communication modes;
triggering a cross-agency communication mode when the number of deployed vehicles and agency role associated with each deployed vehicle are insufficient to manage the incident type;
establishing the cross-agency communication mode by:
comparing device capabilities of the paired communication devices associated with each deployed vehicle;
determining communication commonalities within the device capabilities amongst the paired communication devices of vehicles of different agency roles;
determining one or more frequency channels common to the paired communication devices associated with deployed vehicles of different agency roles; and
establishing communication amongst paired communication devices associated with vehicles of different agency roles using a common channel of the one or more frequency channels common to the paired communication devices associated with the deployed vehicles of different agency roles.

### Claim 2 (depends on 1)

The method of claim 1, wherein establishing further comprises:
establishing communication amongst paired communication devices associated with vehicles of a first agency with paired devices of vehicles of a second different agency on a first common channel, and
establishing communication amongst paired communication devices associated with vehicles of the first agency with devices of vehicles of a third different agency on a second common channel.

### Claim 3 (depends on 1)

The method of claim 1, further comprising:
notifying, via a user interface of the in-vehicle computer, a common channel set up for cross agency communication.

### Claim 4 (depends on 1)

The method of claim 1, further comprising:
sending transcribed text of cross-agency communications for display on in-vehicle computers associated with paired communication devices that cannot communicate on the common channel.

### Claim 5 (depends on 1)

The method of claim 1, wherein pairing the communication device with the in-vehicle computer comprises one of:
pairing the communication device to the in-vehicle computer via a personal area network (PAN);
inputting a pairing command to a user interface of the in-vehicle computer to pair the communication device to the in-vehicle computer; and
hardwiring a mobile radio to the in-vehicle computer.

### Claim 6 (depends on 1)

The method of claim 1, further comprising:
enabling an interoperability field in a codeplug in each paired communication device.

### Claim 7 (depends on 1)

The method of claim 1, wherein the establishing of the cross-agency communication mode by is managed by the in-vehicle computer of each deployed vehicle and at least one of:
a public safety server; and
a vehicular adhoc network (VANET).

### Claim 8

A communication system, comprising:
a plurality of public safety (PS) vehicles associated with different agency roles, each PS vehicle having an in-vehicle computer to which at least one PS communication device is paired, the PS communication device being a converged PS communication device; and
each in-vehicle computer configured to establish cross-agency communication amongst converged PS communication devices associated with vehicles of different agency roles based on a common channel of one or more frequency channels of the converged PS communication devices.

### Claim 9 (depends on 8)

The communication system of claim 8, wherein the cross-agency communication establishes communication amongst PS communication devices associated with PS vehicles of a first agency role with PS communication devices of PS vehicles of a second agency role, on a first common channel, and
establishes communication amongst PS communication devices associated with PS vehicles of the first agency role with PS communication devices of PS vehicles of a third different agency role on a second common channel.

### Claim 10 (depends on 8)

The communication system of claim 8, wherein transcribed text of cross-agency communications are displayed on in-vehicle computers associated with PS communication devices that cannot communicate on the common channel.

### Claim 11 (depends on 8)

The communication system of claim 8, wherein each PS communication device is paired with its respective in-vehicle computer using one of:
pairing the PS communication device to the in-vehicle computer via a personal area network (PAN);
inputting a pairing command to a user interface of the in-vehicle computer to pair the PS communication device to the in-vehicle computer; and
hardwiring a PS mobile radio to the in-vehicle computer.

### Claim 12 (depends on 8)

The communication system of claim 8, wherein each PS communication device includes a codeplug with an interoperability field enabled.

### Claim 13 (depends on 8)

The communication system of claim 8, wherein the cross-agency communication is managed by the in-vehicle computer of each deployed PS vehicle and at least one of:
a public safety server; and
a vehicular adhoc network (VANET).
