For the purposes of the present document, the following terms and definitions apply:
The AP-ID (Access Point-ID) is the physical identity (e.g. MAC address) of the generic IP access network point through which the MS is accessing GAN service. This identifier is provided by the MS (obtained via broadcast from the AP) to the GANC via the Up interface, when it requests GAN service. The AP-ID may be used by the GANC to support location services. The AP-ID may also be used by the service provider to restrict GAN service access via only authorized APs.
MS mode of operation where the NAS layers communicate through either the GERAN RR or the UTRAN RRC entities.
MS mode of operation where the NAS layers communicate through either the GERAN RR, the UTRAN RRC or the E-UTRAN RRC entities.
GAN A/Gb Mode:
MS mode of operation where the NAS layers communicate through the GA-CSR and GA-PSR entities.
GAN Iu Mode:
MS mode of operation where the NAS layers communicate through the GA-RRC CS and GA-RRC PS entities.
Generic Access Network:
This term is used when a procedure applies to both GAN A/Gb mode and GAN Iu mode (e.g., see clause 8.1
, "Mechanism of Mode Selection in Multi-mode terminals").
access network providing access to A/Gb or Iu interfaces via an IP network
Generic Access Network Controller:
network node that connects to the MSC and SGSN via the A-interface and Gb interface (GAN A/Gb mode) or the Iu-cs interface and Iu-ps interface (GAN Iu mode) and enables access via a generic IP network.
Three different logical roles for the GANC are defined in this specification:
Provisioning GANC, Default GANC and Serving GANC.
logical role of a GANC in the HPLMN, which redirects an MS performing the GAN Registration Procedure to a preferred Serving GANC within the HPLMN or VPLMN. The Serving GANC and Default GANC may be the same entity, in which case no redirection is required.
process by which the MS discovers the Default GANC in the HPLMN.
mobile station engaged in a call (a CS domain service) moves between 3GPP access networks and GAN.
mobile station moves from 3GPP access networks to GAN.
mobile station moves from GAN to 3GPP access networks.
A mobile station with one or more ongoing PS domain services moves between a GAN cell and a GERAN/UTRAN cell.
logical role of a GANC in the HPLMN of an MS. When an MS performs the Discovery Procedure to this GANC, the MS is provided the address of the Default GANC in the HPLMN.
process by which a Default or Serving GANC redirects an MS to an alternative Serving GANC. This alternative GANC is likely to become the Serving GANC for the MS.
process by which an MS requests the Generic Access Service from a GANC.
mobile station reselects from 3GPP access networks to GAN.
mobile station reselects from GAN to 3GPP access networks.
action of re-selection between 3GPP access technology and GAN for a mobile station in idle mode.
free from noticeable transitions (i.e. no end-user action is required; speech interruptions are short; service interruptions are short; incoming calls are not missed; packet sessions are maintained; services work identically).
logical role of the GANC in a PLMN which provides an MS with the Generic Access service.
this is a cell on which an MS may camp. It must satisfy criteria which are defined for A/Gb mode in TS 43.022
and for Iu mode in TS 25.304
generally referred to as "mobile station" in this document.
