Idle state definition
Examples of Idle state in a sentence
POM moves the earlier active agent to Idle state and the new active agent to Talking/Busy state.
The chapter also describes how this lightweight connection can be modeled as a new connected state, called herein RRC Connected Inactive [SMS+16], or as an extension of the RRC Idle state under standardization for the LTE-A evolution in Release- 14 [3GPP16-RP160540].
Idle state for a voice service is achieved by connecting a telephone, verifying a dial tone is present, then disconnecting the telephone from the STB.
In order for the network to be able to reach the UE in RRC Idle state, the UE has to monitor the paging channel of the cell it has camped on.
This transition from Idle to Connected state can have detrimental effects in terms of signaling overhead, as the majority of data connections in LTE transfer less than 1Kbyte of data before reverting back to the Idle state and consequently releasing the RAN UE context.
It has been observed in LTE networks that the inactivity timers releasing UE to Idle state are typically configured to be quite short (down to 10-60 seconds) which leads to a high amount of transitions from Idle to Connected.
POM informs the passive agent about this action and makes the passive agent ready to accept a new call by moving the passive agent to Idle state.
Figure 3-3 is not showing the RRC* Idle state, which is mainly intended for fault recovery and fallback procedures in case of link failure, see Figure 3-4.
In RRC Idle state the mobility is UE-based and does not require the transmission of measurement reports and the network contacts the UE via paging.
RRC Idle state is often seen as the primary UE sleeping state in LTE-A, where the network procedures and UE behavior have been optimized for power savings.
