y j2000

Provision of services to mobile and fixed users via a wireless link Provision of multimedia services (in circuit and packet-mode

operation). Support of global roaming Support of the Virtual Home Environment concept Covering of a wide range of user sectors (e.g. public, private,

business, residential, local loop, etc.), radio technologies and

coverage (cellular, satellite, cordless, etc.) Accommodating a wide range of user equipment (e.g. personal

pocket terminals, vehicle mounted terminals, special mobileterminals, standard PSTN/ISDN terminal equipment connected tothe mobile station, etc.).

Key characteristics of the modelling

8/8/2019 IMT2000

30/63

y gapproach

Separation of functions which are dependent on radio access technologyfrom functions which are not dependent on radio access technology.

As much as possible of the network has been definedindependently from the radio access technology.

The concept of IMT-2000 Family of Systems (as outlined in ITU-TRecommendation Q.1701) allows multiplicity of family members:

Family members therefore have the option to selectively implementonly those functions which are needed to support the services theychoose to offer.

RACF - Radio Access Control Function: This FE handles the overall control of theassociation and access link(s) between a mobile terminal and the network.

RACAF - Radio Access Control Agent Function: This FE handles the mobile side of theassociation and access link control between the mobile terminal and the network.

RFTR - Radio Frequency Transmission and Reception : This FE controls theinterconnection and adaptation of the access radio link corresponding to the BS approachlink.

MRTR - Mobile Radio Transmission and Reception: This FE controls the interconnectionand adaptation of the access radio link to the rest of the mobile terminal.

ARF - Access link Relay Function: This FE handles the overall control for the transit of abranch of BS approach link between two instances of RACF.

SIBF - System access Information Broadcast Function: This FE handles the overall controlof system access information broadcasting. The information to be broadcast may be madeavailable to the FE via an operation and maintenance function.

SNCF - Satellite Network Control Function: This FE dynamically controls the configurationof radio network resources, in response to demands for connections to and from mobileterminals. In particular, in satellite networks, optimal use of scarce communicationresources requires this dynamic behaviour.

GPF Geographic Position Function: This FE handles the tasks associated withgeographic positioning in the radio access side.

(III) SDF - Service Data Function: This FE is defined in Recommendation Q.1224 (IN CS-2), however, it

has been enhanced for mobile communications. It handles storage and access to service and networkrelated data and provides consistency checks on data. It hides from SCF the real data implementation

and provides a logical data view to SCF. SCF - Service Control Function: This FE contains the overall IN service control functionality in the

IMT-2000. Service logic is triggered by call processing, mobility management, or non-call associatedevents. The SCF interacts with other FEs to access additional logic or to obtain information (service,user or network data) required to process a service logic instance.

SRF - Specialised Resource Function: This FE is defined in IN Capability Set documents. It providesthe specialised resources required for the execution of IN provided services (e.g. digit receivers,announcements, conference bridges), mobile multimedia services, application data delivery services,and packet transfer services.

SMF - Service Management Function: This FE is defined in Recommendation Q.1224 (IN CS-2),however, it has been enhanced for mobile communications. It consists of a number of IN SMFfunctionality.

SSF - Service Switching Function: This FE is defined in Recommendation Q.1224 (IN CS-2), however,it has been enhanced for mobile communications. The SSF is associated with the CCF. It providesthe set of functions required for the interaction between CCF and SCF.

CCF - Call Control Function (enhanced): The definition of this FE is based on the Call ControlFunction defined in Recommendation Q.1224 (IN CS-2), however, it has been enhanced for mobilecommunications. It provides call/connection processing control.

CnCF - Connection Control Function: This FE provides connection processing control.

(IV) LMF - Location Management Function: This FE contains the basic terminal mobility logic. It supports

location management, mobility management, activation status management, and identitymanagement. The LMF interacts with other FEs to access additional logic or share information (e.g.user or network data). It also handles storage and access to subscriber mobility data.

AMF - Authentication Management Function: This FE handles storage and access to authenticationdata. It also provides the authentication function and confidentiality control.

SACF - Service Access Control Function: This FE provides both call related and call unrelatedprocessing and control (e.g. in relation to mobility management).

GPCF - Geographic Position Control Function: This FE provides the overall control for the geographicposition finding function on the network side.
