Abstract

A determination may be made that a region of the RAN is serving more than a threshold extent of WCDs configured for machine-to-machine communication. The region of the RAN may include a set of one or more wireless coverage areas, and each wireless coverage area in the set of wireless coverage areas may include at least one paging channel. The paging channel parameters of each wireless coverage area in the set of wireless coverage areas may be modified to increase a rate at which the RAN successfully pages WCDs via the set of wireless coverage areas.

obtaining an identifier of a particular wireless M2M communication device served by the region of the RAN, 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 machine-to-machine communication based on information in the profile.

4. The method of claim 1, wherein the threshold extent of wireless M2M communication devices is between 50% and 100% of all wireless communication devices that are served by the RAN in the region.

5. The method of claim 4, wherein the threshold extent of wireless M2M communication devices is between 80% and 100% of all wireless communication devices that are served by the RAN in the region.

6. The method of claim 1, wherein modifying the paging channel parameters of each wireless coverage area in the set of wireless coverage areas further comprises:

reducing the extent of paging concatenation on the paging channels of each wireless coverage area in the set of wireless coverage areas.

7. The method of claim 1, wherein modifying the paging channel parameters of each wireless coverage area in the set of wireless coverage areas further comprises:

increasing a number of paging request messages transmitted to a particular wireless M2M communication device during paging of the particular wireless M2M communication device.

8. The method of claim 1, wherein modifying the paging channel parameters of each wireless coverage area in the set of wireless coverage areas further comprises:

increasing a number of wireless coverage areas through which paging request messages are transmitted to a particular wireless M2M communication device during paging of the particular wireless M2M communication device.

9. The method of claim 1, wherein the each wireless coverage area in the set of wireless coverage areas includes at least one access channel, and wherein modifying the paging channel parameters of each wireless coverage area in the set of wireless coverage areas further comprises:

instructing the wireless M2M communication devices served by the region of the RAN to, during call establishment procedures, increase a power with which they transmit initial access probe messages on the access channel.

10. The method of claim 1, wherein each wireless coverage area in the set of wireless coverage areas includes at least one access channel, and wherein modifying the paging channel parameters of each wireless coverage area in the set of wireless coverage areas further comprises:

instructing the wireless M2M communication devices in the region of the RAN to, during call establishment procedures, increase a number of access probe messages they transmit on the access channel.

11. A system comprising:
