name: A/Gb mode
full_form: A/Gb mode
context: Voice Group Call Service and Voice Broadcast Service are applicable in A/Gb mode only. For mobile stations supporting the Voice Group Call Service or the Voice Broadcast Service, it is explicitly mentioned throughout the present document if a certain procedure is applicable only for such a service and, if necessary, how mobile stations not supporting such a service shall behave. For VGCS and VBS, the following possible mobile station implementations exist: - support of listening to voice broadcast calls (VBS listening); - support of originating a voice broadcast call (VBS originating); - support of listening to voice group calls (VGCS listening); - support of talking in voice group calls (VGCS talking. This always includes the implementation for VGCS listening); - support of originating a voice group call (VGCS originating. This always includes the implementation for VGCS talking). Apart from the explicitly mentioned combinations, all possible combinations are optional and supported by the present document. The related terms are used in the present document, if information on these implementation options is required.
description: The A/Gb mode refers to the operational state of the network where Voice Group Call Service and Voice Broadcast Service are applicable.
explanation: Categorized as a Mode because it defines a specific operational condition for VGCS and VBS services.
