Part 22 of the FCC rules covers certain commercial paging services. Before the cellular telephone netowrks were built in the 1980s most of these frequencies were used by IMTS and other mobile phone systems. They may still be used for this in some areas.

Part 22 Paging Frequency Use by Public Safety and Business/Industrial Users
The FCC auctioned off certain spectrum bands to bidders in various market areas. These licensees can use their frequencies for their own operations or lease or sell their licenses to other entities.
Besides paging, many other types of communications, such as conventional repeater or simplex systems, LTR trunked systems, and various digital voice systems such as P25 and DMR, can be found on Part 22 paging frequencies, especially the 152/158 MHz and 454/459 MHz paired channels. In some areas Part 22 paging channels are used by state and local public safety agencies.
I looked up 152.xxxx in the FCC database and found nothing.
Auctioned Part 22 paging stations are not licensed as individual frequencies at specific sites as is the case with Part 90 private land mobile stations. Stations may be at any location in the license market area and licenses may be partitioned or disaggregated so other frequencies above or below the block center frequency may be used. Block edge frequencies may be used if the licesnsee owns adjoining blocks.
It can be difficult to find license information. Subscribers (end users) may operate under somebody else's license. The FCC license data in the RadioReference.com database does not contain Part 22 licenses. Licenses with a service code of CD (Paging & Radiotelephone) are site based and can be searched on the FCC GMR search page but to find licenses with a service code of CP (Part 22 VHF/UHF Paging excluding 931 MHz) you must use the geosearch function on the FCC ULS license search page.
Go to the FCC ULS Advanced License Search page.
Under Licence Detail check Active.
Under Frequencies check Exact and enter the frequency.
Click Geosearch. That will take you to the next page.
Now check State/County and select your state in the dropdown list.
If you don't select a county it will return all licenses in all market areas in the state. If you want to narrow it down select one or more counties from the dropdown list or check Coordinates to search in a radius circle around a latitude/longitude point.
The frequency should still be populated from what you entered on the previous page.
Click Search.
This will return the licenses for the frequency you entered in any market areas that fall within the locations that you entered.
Paired Paging Channels
The tables below list the VHF high band and UHF paging channels that are used in some areas by Public Safety and Business/Industrial conventional and trunked systems.
