3GPP43.129Packet-switched handover for GERAN A/Gb modeRelease 17Stage 2TS

3.1 Definitions

For the purposes of the present document, the terms and definitions given in 3GPP TR 21.905 [1] and the following apply:

Active PFCs: that subset of the PFCs to be handed over, for which the source BSS has determined that resources should be allocated in the target cell during the PS Handover preparation phase.

A/Gb mode: MS mode operation where the MS is connected to the Core Network via GERAN and the A and/or Gb interfaces.

Blind Transmission: refers to the decision made by the SGSN to start the transmission of downlink N-PDUs or by the target BSS/GANC to start the transmission of downlink LLC PDUs for a given mobile station before receiving confirmation that the PS handover procedure has been successfully completed.

GAN Mode: MS mode of operation where the MS is connected to the Core Network via a GANC and the A and/or Gb interfaces.

PFC subject to handover: refers to an MS’s PFC for which the packet switched handover procedure is to be initiated when a cell change is required. Whether a PFC needs handover or not is decided by the BSS. This decision criteria is not standardized.

Source to Target Transparent Container: This container is encoded as "Source RNC to Target RNC transparent container" in case of PS handover to UTRAN and as "Source eNB to Target eNB transparent container" in case of PS handover to E-UTRAN. It replaces the "Source RNC to Target RNC Transparent container" used in previous releases.

Target to Source Transparent Container: This container is encoded as "Target RNC to Source RNC transparent container" in case of PS handover to UTRAN and as "Target eNB to Source eNB transparent container" in case of PS handover to E-UTRAN. It replaces the "Target RNC to Source RNC Transparent container" used in previous releases.

CSG Cell: A UTRAN or E-UTRAN cell for which the reported access mode indicates "Closed access mode" (see [36]).

Hybrid Cell: A UTRAN or E-UTRAN cell for which the reported access mode indicates "Hybrid access mode" (see [36]).
