Abstract

A mobile communication device of an apparatus in one example is configured for communication through employment of a cellular service and a personal radio service.

Claims

1. An apparatus, comprising:

a mobile communication device configured for communication through employment of a cellular service and a personal radio service (PRS).

2. The apparatus of claim 1, wherein the mobile communication device comprises a first mobile communication device that initiates a communication session with a second mobile communication device, wherein the second mobile communication device is configured for communication through the cellular service and the PRS;

wherein the first mobile communication device employs the cellular service or the PRS for the communication session based on a determination that a distance between the first mobile communication device and the second mobile communication device is within a coverage range of the PRS.

3. The apparatus of claim 2, further comprising:

a service application component of a cellular service network for the first mobile communication device that provides the cellular service to the first mobile communication device;

wherein the service application component is configured to make the determination upon receipt of an origination attempt trigger or termination attempt trigger.

4. The apparatus of claim 3, wherein the service application component is configured to obtain a location of the second mobile communication device from a mobile location center of a cellular service network for the second mobile communication device.

5. The apparatus of claim 3, wherein the service application component is configured to send an SMS message to the second mobile communication device to obtain a location of the second mobile communication device.

6. The apparatus of claim 3, wherein the service application component is configured to send a notification of the communication session over the PRS to the second mobile communication device.

7. The apparatus of claim 3, wherein the service application component is configured to select a channel for the communication session over the PRS;

wherein the service application component is configured to send a notification of the channel for the communication session over the PRS to the first and second mobile communication devices.

8. The apparatus of claim 3, further comprising:

an intelligent peripheral of the cellular service network for the first mobile communication device;

wherein the intelligent peripheral prompts a user of the first mobile communication device to select the cellular service or the PRS if the distance between the first mobile communication device and the second mobile communication device is within the coverage range of the PRS.

9. The apparatus of claim 2, wherein the first mobile communication device prompts a user of the first mobile communication device to select the cellular service or the PRS if the distance between the first mobile communication device and the second mobile communication device is within the coverage range of the PRS.

10. The apparatus of claim 2, wherein the first and second mobile communication devices are configured to initiate the communication session.

11. The apparatus of claim 10, wherein the first and second mobile communication devices exchange one or more short message service (SMS) messages to initiate the communication session.

12. The apparatus of claim 2, wherein the first and second mobile communication devices employ the PRS over a PRS channel for the communication session;

wherein the PRS channel for the communication session is predetermined before the first mobile communication device initiates the communication session.

13. The apparatus of claim 12, wherein the PRS channel is based on one or more of:

a mobile directory number of the first mobile communication device; and

a mobile directory number of the second mobile communication device.

14. The apparatus of claim 2, wherein the first and second mobile communication devices employ the PRS over a PRS channel for the communication session;

wherein the PRS channel for the communication session is dynamically selected after the first mobile communication device initiates the communication session.

15. The apparatus of claim 14, wherein the PRS channel is based on one or more of:

current usage of available PRS channels;

recent usage of the available PRS channels;

a random selection from the available PRS channels.

16. The apparatus of claim 1, wherein the mobile communication device is configured to automatically switch to the PRS when the cellular service is not available.

17. The apparatus of claim 1, wherein the cellular service comprises a code division multiple access (CDMA) service or a global system for mobile communications (GSM) service.

18. The apparatus of claim 1, wherein the PRS comprises a family radio service (FRS), a general mobile radio service (GMRS), a citizens band radio service (CB), a multi-use radio service (MURS), a private/professional mobile radio service (PMR), or a public access mobile radio service (PAMR).

19. A method, comprising the steps of:

receiving a request for a communication session between a first mobile communication device and a second mobile communication device;

making a determination of a distance between the first mobile communication device and the second mobile communication device; and

selecting between a personal radio service (PRS) and a cellular service for the communication session based on the determination of the distance between the first mobile communication device and the second mobile communication device.

20. The method of claim 19, wherein the step of making the determination of the distance between the first mobile communication device and the second mobile communication device comprises the steps of:

obtaining a location of the first mobile communication device from one of the first mobile communication device and a cellular service network of the first mobile communication device; and

obtaining a location of the second mobile communication device from one of the second mobile communication device and a cellular service network of the second mobile communication device.

21. The method of claim 20, wherein the step of obtaining the location of the second mobile communication device from one of the second mobile communication device and the cellular service network of the second mobile communication device comprises the step of:

sending a short message service (SMS) message to the second mobile communication device to request the location of the second mobile communication device.

22. The method of claim 19, wherein the step of selecting between the PRS and the cellular service for the communication session comprises the step of:

prompting a user of the first mobile communication device for a selection of the PRS or the cellular service.

23. The method of claim 19, further comprising the step of:

selecting a PRS channel for the communication session upon a selection of the PRS for the communication session.

24. The method of claim 23, wherein the step of selecting the PRS channel for the communication session upon the selection of the PRS for the communication session comprises the step of:

selecting the PRS channel based on one or more of;

a mobile directory number of the first mobile communication device; and

a mobile directory number of the second mobile communication device.

25. The method of claim 23, wherein the step of selecting the PRS channel for the communication session upon the selection of the PRS for the communication session comprises the steps of:

selecting the PRS channel from a set of available PRS channels based on one or more of;

current usage of the set of available PRS channels;

recent usage of the set of available PRS channels;

a random selection from the available PRS channels; and

indicating the PRS channel to the first mobile communication device and the second mobile communication device.

26. The method of claim 19, further comprising the step of:

switching automatically from the cellular service to the PRS when the cellular service is not available.
