3GPP43.318Generic Access Network (GAN)Release 16Stage 2TS
For the purposes of the present document, the following terms and definitions apply:
AP-ID: 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.
GERAN/UTRAN Mode: MS mode of operation where the NAS layers communicate through either the GERAN RR or the UTRAN RRC entities.
GERAN/UTRAN/E-UTRAN Mode: 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.
GAN Mode: 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").
Generic Access Network: 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.
default 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.
discovery procedure: process by which the MS discovers the Default GANC in the HPLMN.
CS handover: mobile station engaged in a call (a CS domain service) moves between 3GPP access networks and GAN.
handover in: mobile station moves from 3GPP access networks to GAN.
handover out: mobile station moves from GAN to 3GPP access networks.
PS handover: A mobile station with one or more ongoing PS domain services moves between a GAN cell and a GERAN/UTRAN cell.
provisioning GANC: 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.
redirection: 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.
registration procedure: process by which an MS requests the Generic Access Service from a GANC.
rove in: mobile station reselects from 3GPP access networks to GAN.
rove out: mobile station reselects from GAN to 3GPP access networks.
roving: action of re-selection between 3GPP access technology and GAN for a mobile station in idle mode.
seamless: 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).
serving GANC: logical role of the GANC in a PLMN which provides an MS with the Generic Access service.
suitable cell: this is a cell on which an MS may camp. It must satisfy criteria which are defined for A/Gb mode in 3GPP TS 43.022 and for Iu mode in 3GPP TS 25.304.
user equipment: generally referred to as "mobile station" in this document.
