Summary
Introduction
This chapter will describe how the tools and models discussed in the last chapters are collected and organized to develop a comprehensive admission control process for three-tier spectrum bands, such as a Spectrum Access System (SAS). This will include an inventory of the models needed to construct an admission control system, and a high level description of the stateful information needed to perform the functions that are required to support the spectrum management regime. By necessity and for clarity, there will be some overlap with the discussion of methods in prior chapters.
The concept of the admission control system is a simple transaction processing system with a persistent state. The main transactions processed by the admission control system are described in more detail in other chapters. In this chapter, we will examine the fundamental functions of any admission control system that supports three-tier spectrum, and make this discussion as independent of the specific regime as possible. Also, we will abstract the complex algorithms that are the heart of the admission control system processing and only consider their functionality, not their internal design or level of implementation.
Later in this book (Chapter 13), the specifics of the admission control system for the US implementation of the Citizens Broadband Radio Service (CBRS) SAS and rules will be developed in detail, on a message by message, and object by object basis. This design is only one possible implementation of the fundamental interaction needs that are developed in this chapter.
Major Admission Control System and Device Transactions
The transactions that are described in this chapter generally mirror those that will be described in greater detail in Chapter 13. The functional grouping of the admission control system device transactions capabilities are:
Inquiry Provide device with information regarding spectrum environment, but make no changes to spectrum usage.
Grant Request Request a spectrum grant, and make any necessary adjustments to peer or lower-tier users.
Authorization Provide continued authorization to utilize a spectrum grant for a fixed duration of time.
Relinquish Relinquish a spectrum grant, and adjust the aggregate interference to reflect this removal of a node.
Reclaim A higher-tier user declares right to spectrum, or is detected, and that right is invoked.
