Full Description

The present document's scope is the Release 99 of the 3GPP specifications to which it refers. This document is notcurrently planned to be kept updated beyond December 2000.

The present document defines a baseline set of capability requirements that enable all UEs to "register" with allapplicable 3GPP networks (depending on the availability of a appropriate subscription). It describes all the functionsthat a UE has to perform in order to "exist" within a 3GPP network. These functions are used to derive requirements forall aspects of UE baseline capability. The present document also identifies different UE Service Capabilities and thefunctions that a UE must perform in order to access a service. The actual capabilities that a UE must posses to meetthese requirements are identified in the report and in some instances listed in the Annexes to the present document, aswell as being described in the referenced implementation specifications.

The present document introduces the concept of "service-less UE" which can exist in the network but provides no userservice. Although this is not a marketable UE type it describes from the standardisation viewpoint a baseline set ofcapabilities to which specific service-related UE capabilities can then be added.

The present document should not be used as the sole basis for UE design, only as an informative indication ofcapabilities required to support a given functionality, and as a pointer to the location of text describing saidfunctionality, in the core specifications.

UE capability requirements may include some regulatory requirements (mandatory requirements). However, it is notintended to identify them as such in this report. Some of the requirements identified in this document as essential, maytherefore also be "mandatory" according to the definition of that term appearing herein.
