The cdma2000 System for Mobile Communications: 3G Wireless Evolution

Chapter 2 Architecture

The cdma2000 wireless network can be viewed as a collection of logical entities and the associated interfaces. A logical entity is an implementation-independent representation of a function or set of functions, and it may not correspond to a physical device. A reference point is the point of connection between adjacent logical entities. A reference point is also called an interface if the logical devices it connects correspond to separate physical devices. The reference point is specified in terms of a set of procedures and associated signaling that define the operational responsibility of the connected network entities. The cdma2000 interfaces are fully standardized, or open, which allows the operators to deploy a network ...
