摘要
Systems and methods for providing access prioritization to a private Long Term Evolution (LTE) network operating in a Citizens Broadband Radio Service (CBRS) spectrum include receiving, at a network device of the private Long Term Evolution (LTE) network, a functional group associated with a user equipment (UE) and a traffic load of a cell of the private LTE network associated with the UE. An access priority associated with the functional group and the traffic load is determined and provided to a CBRS access point (AP) which controls access to the cell. The access priority indicates to the CBRS AP a priority with which the UE is allowed to access the cell and can include a high priority, a low priority, or no access indication.
說明書
This application is a continuation of U.S. Non-Provisional patent application Ser. No. 16/672,123, filed Nov. 1, 2019, the full disclosure of which is hereby expressly incorporated by reference in its entirety.
The present technology pertains to enterprise networks, and more specifically to prioritization of access to private Long Term Evolution (LTE) service in a Citizens Broadband Radio Service (CBRS) spectrum, based on enterprise group affiliation.
The Citizen Broadcast Radio Service (CBRS) is a 150 MHz wide spectrum in the 3550-3700 MHz frequency range in the United States. Some of this spectrum is used by the United States government for their radar systems. When portions of the spectrum are not in use, those portions can be made available for use by other entities. The Federal Communications Commission (FCC) created rules for commercial use of the CBRS spectrum. Enterprises can use this CBRS spectrum to set up private Long-term Evolution (LTE) networks and allow access to consumer and Internet of Things (IoT) devices. Enterprises may expand and increase the coverage density of private LTE networks by integrating CBRS into their wireless connectivity services. CBRS style shared spectrum in some other bands is also being planned in Europe and some other parts of the world.

What is claimed is:1. A method comprising:assigning, to a first functional group associated with a user equipment (UE), a first priority to access a first cell of a private cellular network operating in a Citizens Broadband Radio Service (CBRS) spectrum, the first priority being different than at least one of a second priority of the first functional group to access a second cell of the private cellular network or a third priority of a second functional group to access the second cell; mapping the first functional group to a cell identifier of the second cell and to the second priority to access the second cell; mapping the second functional group to a cell identifier of the first cell and to a fourth priority to access the first cell, the fourth priority being different than the first priority; receiving, at a network device of the private cellular network, an indication of a condition of the first cell of the private cellular network; determining, for the first functional group, an access priority for the UE to access the first cell, the access priority being based on the first priority to access the first cell and the indication of the condition of the first cell; and providing the access priority to a CBRS access point (AP) that controls access to the first cell, wherein the access priority indicates to the CBRS AP a cell-specific priority with which the UE is allowed to access the first cell. 2. The method of claim 1 , wherein the condition of the first cell of the private cellular network comprises at least one of a traffic load of the first cell or available resources of the first cell, and wherein the access priority comprises a high priority, a low priority, or a no access indication. 3. The method of claim 1 , wherein the access priority for the UE comprises a no access indication based on a determination that the UE is authenticated to attach to the first cell and one or more UEs of functional groups with a higher priority than the access priority consume a traffic load of the first cell. 4. The method of claim 3 , wherein the no access indication is temporary for a period of time until a traffic load of the first cell decreases. 5. The method of claim 1 , further comprising:mapping the second functional group to the cell identifier of the second cell and to the third priority to access the second cell, the third priority being different than the second priority. 6. The method of claim 1 , wherein providing the access priority to the CBRS AP includes providing the access priority to a mobility management entity (MME) of the private cellular network, the method further comprising:receiving, at the network device and from the MME, the first functional group in response to the UE establishing a request to attach to the first cell. 7. The method of claim 1 , further comprising receiving a user profile and subscription information associated with the UE from one or more authentication, authorization, and accounting (AAA) servers of the private cellular network. 8. A system, comprising:one or more processors; and at least one non-transitory computer-readable medium containing instructions which, when executed by the one or more processors, cause the one or more processors to:assign, to a first functional group associated with a user equipment (UE), a first priority to access a first cell of a private cellular network operating in a Citizens Broadband Radio Service (CBRS) spectrum, the first priority being different than at least one of a second priority of the first functional group to access a second cell of the private cellular network or a third priority of a second functional group to access the second cell; map the first functional group to a cell identifier of the second cell and to the second priority to access the second cell; receive, at a network device of the private cellular network, an indication of a condition of the first cell of the private cellular network, wherein the network device is a Digital Network Architecture (DNA) appliance of the private cellular network; determine, for the first functional group, an access priority for the UE to access the first cell, the access priority being based on the first priority to access the first cell and the indication of the condition of the first cell; and provide the access priority to a CBRS access point (AP) that controls access to the first cell, wherein the access priority indicates to the CBRS AP a cell-specific priority with which the UE is allowed to access the first cell. 9. The system of claim 8 , wherein the condition of the first cell of the private cellular network comprises at least one of a traffic load of the first cell or available resources of the first cell, and wherein the access priority comprises a high priority, a low priority, or a no access indication. 10. The system of claim 8 , wherein the access priority for the UE comprises a no access indication based on a determination that the UE is authenticated to attach to the first cell and one or more UEs of functional groups with a higher priority than the access priority consume a traffic load of the first cell. 11.
