Abstract

A determination may be made that resources from wireless coverage areas of a radio access network (RAN) are to be assigned to a particular wireless communication device (WCD), and that the particular WCD is configured for machine-to-machine (M2M) communication. Possibly in response to making the determination, the RAN may assign resources from a first extent of wireless coverage areas for substantially simultaneous communication between the RAN and the particular WCD. For other WCDs not configured for M2M communication, resources from a second extent of wireless coverage areas may be assigned for substantially simultaneous communication between the RAN and the other WCDs. The first extent may be greater than the second extent.

Claims

1. A method comprising:

making a determination, by a radio access network (RAN) device, that resources from base transceiver stations (BTSs) of the RAN are to be assigned to a particular wireless machine-to-machine (M2M) communication device configured for M2M communication, wherein the BTSs of the RAN also serve wireless non-M2M communication devices; and

in response to making the determination, the RAN assigning resources from a first number of BTSs to provide a first number of transmission paths for communication between the RAN and the particular wireless M2M communication device, wherein the RAN assigning resources from the first number of BTSs comprises the RAN providing instructions to the particular wireless M2M communication device to adjust a maximum number of wireless coverage areas in an active set of the particular wireless M2M communication device to accommodate the first number of transmission paths, wherein, for a wireless non-M2M communication device, the RAN assigns resources from a second number of BTSs to provide a second number of transmission paths for communication between the RAN and the wireless non-M2M communication device, wherein the first number of BTSs is greater than the second number of BTSs, wherein the first number of transmission paths is greater than the second number of transmission paths, and wherein the first number of BTSs provides greater bearer channel capacity than the second number of BTSs.

2. The method of claim 1, wherein the particular wireless M2M communication device being configured for M2M communication comprises the particular wireless M2M communication device being configured to autonomously initiate or receive communication from another networked device without substantive interaction with a human user.

3. The method of claim 1, further comprising:

obtaining an identifier of the particular wireless M2M communication device;

using the identifier of the particular wireless M2M communication device to locate a profile of the particular wireless M2M communication device in a device database; and

determining that the particular wireless M2M communication device is configured for M2M communication based on information in the profile.

4. The method of claim 1, wherein the communication between the RAN and the particular wireless M2M communication device comprises:

during establishment of a call involving the particular wireless M2M communication device, assigning, to the particular wireless M2M communication device, respective traffic channels from each of the first number of BTSs.

5. The method of claim 4, wherein the communication between the RAN and the particular wireless M2M communication device comprises:

during an initial portion of the call, the RAN exchanging bearer traffic with the particular wireless M2M communication device via each of the assigned traffic channels.

6. The method of claim 5, wherein the RAN transmits and receives identical copies of the same bearer traffic via each of the assigned traffic channels.

7. The method of claim 1, wherein the communication between the RAN and the particular wireless M2M communication device comprises:

the RAN transmitting channel assignment messages to the particular wireless M2M communication device via each of the first number of transmission paths.

8. The method of claim 1, wherein the communication between the RAN and the particular wireless M2M communication device via the first number of transmission paths comprises:

the communication traversing each transmission path in the first number of transmission paths at approximately the same time.

9. The method of claim 1, wherein assigning resources from the first number of BTSs results in greater call establishment success rates for the particular wireless M2M communication device than assigning resources from the second number of BTSs does for the wireless non-M2M communication device.

10. The method of claim 1, wherein assigning resources from the first number of BTSs results in greater communication speeds for the particular wireless M2M communication device than assigning resources from the second number of BTSs does for the wireless non-M2M communication device.

11. The method of claim 1, wherein the RAN assigning resources from the first number of BTSs further comprises:

the RAN increasing a maximum acceptable difference between (i) a strength of a signal from a primary wireless coverage area received by the particular wireless M2M communication device and (ii) a minimum strength of a signal from a secondary wireless coverage area received by the particular wireless M2M communication device, wherein increasing the maximum acceptable difference configures the particular wireless M2M communication device for communication with the RAN by way of the first number of transmission paths.

12. A system comprising:

a radio access network (RAN) comprising a plurality of base transceiver stations (BTSs); and

a RAN device, within the RAN, configured to assign resources from a first number of the BTSs to provide a first number of transmission paths for communication between the RAN and a wireless machine-to-machine (M2M) communication device served by the RAN, and also configured to assign resources from a second number of the BTSs to provide a second number of transmission paths for communication between the RAN and a wireless non-M2M communication device served by the RAN, wherein the RAN device assigning resources from the first number of BTSs comprises the RAN device providing instructions to the wireless M2M communication device to adjust a maximum number of wireless coverage areas in an active set of the wireless M2M communication device to accommodate the first number of transmission paths, wherein the wireless M2M communication device is configured for M2M communication, and the wireless non-M2M communication device is not configured for M2M communication, wherein the first number of BTSs is greater than the second number of BTSs, wherein the first number of transmission paths is greater than the second number of transmission paths, and wherein the first number for BTSs provides greater bearer channel capacity than the second number of BTSs.
