Abstract: Solutions are disclosed that provide intelligent adaptive measurement gaps for low mobility user equipment (UEs), such as home internet access points. Because low mobility (stationary use) UE do not move, or move only infrequently, the frequency for of handovers to neighboring cells is reduced, lowering the urgency of measuring signal reception from neighboring cells. A wireless network determines that a first UE is associated with a stationary use, and that a second UE is not. The network transmits a first radio resource control (RRC) message specifying a measurement gap repetition period (MGRP) and an indication to skip at least one measurement gap, to the first UE, and transmits a second RRC message specifying the MGRP, without an indication to skip a measurement gap, to the second UE. In some examples, the MGRP is indicated as having one of four values: 20 milliseconds (ms), 40 ms, 80 ms, and 160 ms.

Abstract: Solutions are disclosed that perform intelligent select whether to transmit a system information block 1 (SIB1) message to a user equipment (UE) during a handover. The wireless network determines whether the UE will be moving to a target basestation having a different tracking area code (TAC) than the source basestation. If so, the source basestation sends the SIB1 for the target basestation to the UE with the handover command, so that the UE is alerted to perform a mobility registration update (MRU) with the new TAC. However, if the UE will be moving to a target basestation having the same TAC as the source basestation, the source basestation sends the handover command without the SIB1 for the target basestation, to save network bandwidth. In some examples, the source basestation queries the target basestation to learn the TAC of the target basestation.
