4. The system of claim 1 , wherein the instructions further cause the at least one processor to:
receive the access request for the first spectrum band from the second user equipment, wherein transmission of the access request to the first spectrum access system is in response to the access request being received.
5. The system of claim 1 , wherein:
the registration request message is transmitted to the first spectrum access system without transmitting any other messages to the first spectrum access system, and
the registration response message is received from the first spectrum access system without receiving any other messages from the first spectrum access system.
6. The system of claim 5 , wherein the registration request message comprises an indication of the first spectrum band within the second spectrum band, and wherein reception of the grant of the access rights is in response to the first spectrum access system determining that the first spectrum band is available for use based on an inventory of spectrum resources associated with the second spectrum band as maintained by the first spectrum access system.
7. The system of claim 1 , wherein transmission of the access request for the first spectrum band to the first spectrum access system is via an application programming interface associated with an application executing on the second user equipment.
8. The system of claim 1 , wherein transmission of the access request for the first spectrum band to the first spectrum access system is via an application programming interface associated with an operating system of the second user equipment.
9. The system of claim 1 , wherein the instructions further cause the at least one processor to:
terminate the device-to-device communication link between the system and the user equipment by transmitting, to the first spectrum access system, a spectrum release message for the first spectrum band.
10. The system of claim 1 , wherein:
the registration request message is a Citizens Broadband Radio Service (CBRS) Registration Request message that comprises the access request for the first spectrum band,
the registration response message is a CBRS Registration Response message that comprises the grant of the access rights, and
the device-to-device communication link is established without exchanging any other messages, other than the CBRS Registration Request message and the CBRS Registration Response message, with the first spectrum access system.
11. A method, comprising:
transmitting, by a system comprising at least one processor to a first spectrum access system via a radio access network, a registration request message comprising a request for first access rights to a first spectrum band, wherein the first spectrum band is wholly contained within a second spectrum band for which the first spectrum access system is granted second access rights from a second spectrum access system, distinct from the first spectrum access system;
obtaining, by the system, a registration response message, comprising a grant of the first access rights to the first spectrum band, from the first spectrum access system in response to the registration request message, the first access rights to the first spectrum band being granted by the first spectrum access system without exchanging any messages with the second spectrum access system; and
in response to obtaining the first access rights, initiating, by the system via the first spectrum band, a point-to-point communication link between a first user equipment at which the system operates and a second user equipment, wherein the device-to-device communication link does not traverse any network elements of the radio access network between the first user equipment and the second user equipment.
12. The method of claim 11 , wherein the point-to-point communication link is a second point-to-point communication link, and wherein the method further comprises:
establishing, by the system, a first point-to-point communication link between the first user equipment and the second user equipment, wherein the transmitting of the request for the first access rights comprises transmitting the request for the first access rights in response to the first point-to-point communication link being established.
13. The method of claim 12 , wherein the first point-to-point communication link is associated with a first radio access technology, and wherein the second point-to-point communication link is associated with a second radio access technology that is distinct from the first radio access technology.
14. The method of claim 11 , further comprising:
receiving, by the system, the request for the first access rights from the second user equipment, wherein the transmitting of the request for the first access rights comprises relaying the request for the first access rights to the first spectrum access system in response to the receiving.
15.
