Title:	Terminology in T2 SWG6 (TR21.904)

Document for:	Discussion 

___________________________________________________________________________

Introduction

Following the decision by SA to produce and maintain sole and common vocabulary document (TR21.905) in 3GPP, T2 SWG6 studied and found out terminology used in TR21.904. Further more, based on the contribution from NEC, T2-991009, T2 SWG6 agreed to have new terms and conditions which gives more clear definition to ‘mandatory/optional’ issues.

Discussion

T2 SWG6 would like T2 to endorse this output from T2 SWG6 for sending SA1. And also T2 SWG6 would like T2 to decide that this kind of terminology issues are to be sent in a way as one document for T2, which include all T2’s document terminology in one document. And further more to decide whether new terms and definition are to be dealt with in the same document or separately.

Proposal

Terminology in TR21.904

Baseline capabilities: capabilities that are required for a service-less UE to operate within a network. The baseline capabilities for a UE include the capabilities to search for, synchronize with and register (with authentication) to a network. The negotiation of the UE and the network capabilities, as well as the maintenance and termination of the registration are also part of the required baseline capabilities.
Baseline Implementation Capabilities (BIC): set of Implementation capabilities, in each technical domain, required to enable a UE to support the required Baseline capabilities.
Implementation capability: a capability that relates to a particular technical domain. Examples: a spreading factor of 128 (in the domain of the physical layer); the A5 algorithm; a 64 bit key length  (in the domain of security); a power output of 21 dBm (in the domain of transmitter performance); support of AMR Codec (in the domain of the Codec); support of CHV1 (in the domain of the USIM).
UE Service Capabilities (USC): capabilities that can be used either singly or in combination to deliver services to the user. The characteristic of UE Service Capabilities is that their logical function can be defined in a way that is independent of the implementation of the UMTS system (although all UE Service Capabilities are of course constrained by the implementation of UMTS). Examples: a data bearer of 144 kbps; a high quality speech teleservice; an IP teleservice; a capability to forward a speech call.
Service Implementation Capabilities (SIC): set of Implementation capabilities, in each technical domain, required to enable a UE to support a set of UE Service Capabilities.
service relationship: the association between two or more entities engaged in the provision of services.
service-less UE: a UE that has only the Baseline capabilities.

Terminology proposed in T2-991009

Mandatory UE Requirement ; Regulatory requirement which is applicable to 3G UEs.   It is determined by each country/region and beyond the scope of 3GPP specification.
e.g. Spurious emission in UK 

Essential UE Requirement (Unconditional); Requirement which has to be implemented in any 3G UE in order to exist in and communicate with 3G network.
e.g. Chiprate of 3.84Mcps

Essential UE Requirement (Conditional) ; Requirement which has to be implemented under certain Service conditions.  
e.g. AMR codec in UE which supports speech service

Optional UE Requirement ; Any other requirements than 3 requirements listed above.   It is totally up to individual manufacturer to decide whether it should be implemented or not. 
e.g.
