C.1 Measurement Report for Handover and Cell Change Order to GAN A/Gb mode

3GPP44.318Generic Access Network (GAN)Mobile GAN interface layer 3 specificationRelease 17TS

The MS uses the (Source-RAT) measurement report procedure to "request" handover to GANA/Gb mode for voice call or signalling session. It also uses it to "request" a Cell Change Order to GAN A/Gb mode for packet data session.

The procedure is initiated after the MS has successfully registered with the GANC, provided the following conditions are met:

– the MS stays registered with GANC;

– the GANC directs the MS to operate in GAN A/Gb mode;

– the GANC includes the IE "GAN Cell Description" in the GA-RC REGISTER ACCEPT message;

– if the source RAT is GERAN/UTRAN, and the MS is in dedicated mode (signalling only or speech mode), network has requested reports according to NETWORK_CONTROL_ORDER or in DTM mode (simultaneous dedicated mode and packet transfer mode) or UTRA RRC Connected Mode for CS domain services;

– the ARFCN provided by the GANC (i.e. the GAN-ARFCN) is within the cell info list used for measurement reporting in the source RAT;

– no GSM neighbour cell matching the {GAN-ARFCN, GAN-BSIC} couple has been detected by the MS.

The MS shall not be connected to more than one GANC at any one time, and therefore shall not report more than one {GAN-ARFCN, GAN-BSIC} couple during the period of the connection to the GANC.

The RR entity in the source RAT shall report that the cell associated with the {GAN-ARFCN, GAN-BSIC} couple has the best possible receiving level (i.e., RxLev = 63).
