Abstract

A facility for performing employing multiple frequencies in a secure distributed hierarchical convergence network is described. The facility receives a signal in a first frequency, converts the received signal to an internal representation, applies a business rule to the converted signal, and, when the business rule indicates that the signal should be transmitted in a second frequency, causes the internal representation of the signal to be translated to a second frequency and transmitted in the second frequency.

Claims (56)

1. A method of employing multiple frequencies to provide a push-to-talk service, comprising:

receiving, at a first peering point communicatively coupled to a peer-to-peer network, a first wireless signal from a push-to-talk device, the first wireless signal communicated in a first frequency;

down-converting, at the first peering point, the received first wireless signal to a down-converted digital signal;

applying a business rule to the down-converted digital signal, wherein the business rule comprises a secure-network portable policy comprising enabling criteria and actions, wherein the enabling criteria describes conditions that are to be in effect at an active peering point, and wherein the actions indicate actions to be taken by the active peering point when the secure-network portable policy becomes active;

when the business rule indicates that the down-converted digital signal should be transmitted in a second frequency, communicating information of the down-converted digital signal through the peer-to-peer network to a second peering point that is communicatively coupled to the peer-to-peer network;

translating, at the second peering point, the down-converted digital signal into a second wireless signal configured to be communicated to a remote communication device via the second frequency, wherein the second frequency is different from the first frequency; and

transmitting the second wireless signal in the second frequency from the second peering point.

2. The method of claim 1 wherein the first wireless signal is received on a first wireless communications network communicatively coupled to the first peering point, and wherein the second wireless signal is transmitted from the second peering point that is communicatively coupled to a second wireless communications network.

3. The method of claim 2 wherein applying the business rule further comprises:

determining that the second wireless communications network has sufficient capacity to transmit the second wireless signal in the second frequency;

identifying a third wireless signal communicated over the second wireless communications network that has a lower priority than the second wireless signal; and

allowing the second wireless signal to be communicated over the second wireless communications network and not allowing the third wireless signal to be communicated over the second wireless communications network.

4. The method of claim 1 further comprising controlling a throughput by throttling the down-converted digital signal when causing the down-converted digital signal to be translated to the second frequency and transmitted in the second frequency.

5. The method of claim 1 further comprising:

prioritizing the first wireless signal among a plurality of other signals communicated from the second peering point so that the first wireless signal having a higher priority receives a better quality of service than other ones of the plurality of other signals having a lower priority.

6. The method of claim 5 further comprising caching at least one of the plurality of other signals having the lower priority so that the first wireless signal having the higher priority can be sent before cached ones of the plurality of other signals having the lower priority.

7. A system of employing multiple different communication frequencies to provide a push-to-talk service from a push-to-talk device to at least one other wireless communication device via a peer-to-peer network, comprising:

a first wireless communications network operable to communicate first wireless signals from and to the push-to-talk device using a first frequency; and

a first peering point communicatively coupled to the peer-to-peer network and communicably coupled to the first wireless communications network, wherein the first peering point is operable to down-convert a first wireless signal received in the first frequency from the push-to-talk device into a digital signal in accordance with a business rule, transform a payload of the digital signal, and identify a second wireless communications network to which the payload of the digital signal should be transferred to, wherein the business rule comprises a secure-network portable policy comprising enabling criteria and actions, wherein the enabling criteria describes conditions that are to be in effect at an active peering point, and wherein the actions indicate actions to be taken by the active peering point when the secure-network portable policy becomes active;

a second peering point communicatively coupled to the first peering point via the peer-to-peer network, wherein the second peering point is operable to receive the digital signal payload from the first peering point, and translate the down-converted digital signal into a second wireless signal configured to be communicated to the at least one other wireless communication device; and

the second wireless communications network communicatively coupled to the second peering point, wherein the second wireless communications network is operable to communicate the second wireless signal with the digital signal payload from the push-to-talk device to the at least one other wireless communication device using a second frequency that is different from the first frequency.

8. The system of claim 7 further comprising a component that translates the digital signal payload to a form recognized by the at least one other wireless communication device.

9. The system of claim 7 further comprising a policy management engine that identifies and enforces a policy to the down-converted digital signal.

10. The system of claim 9 wherein the policy is to prioritize the digital signal.

11. The system of claim 9 wherein the policy is to throttle signals provided to the second network.

12. The system of claim 9 wherein the policy is to cache down-converted digital signals when insufficient capacity exists on the second network so that the digital signals can be provided to the second peering point when additional capacity exists.

13. A non-transitory computer-readable medium having computer-executable instructions for performing a method of employing multiple frequencies, the method comprising:

receiving, at a first peering point communicatively coupled to a peer-to-peer network, a first wireless signal from a first wireless communications network, wherein the first wireless signal is communicated from a push-to-talk device in a first frequency, the first wireless signal including a signal payload and including at least an identifier of a second wireless communications network;

converting, at the first peering point, at least the signal payload of the received first wireless signal to a digital signal payload;

applying a business rule to the first wireless signal, wherein the business rule comprises a secure-network portable policy comprising enabling criteria and actions, wherein the enabling criteria describes conditions that are to be in effect at an active peering point, and wherein the actions indicate actions to be taken by the active peering point when the secure-network portable policy becomes active; and
