Abstract: Disclosed are methods and systems for requesting a UE to forgo handover to a congested neighbor. In particular, a wireless communication system may serve the UE over an air interface connection between the UE and the first base station. While serving the UE, the wireless communication system may receive from the UE a handover request requesting a handover of the UE from the first base station to a second base station. In response to receiving from the UE the handover request, the wireless communication system may determine that the second base station is threshold congested, and, responsive to the determining, (i) deny the handover request and (ii) send to the UE a command for the UE to withhold transmission of further requests for handover of the UE from the first base station to the second base station.

Abstract: Disclosed is a method and system in which connections are pre-established without any UE association and are then a pre-established connection is selected and associated with a UE when the UE seeks to attach. Each pre-established connection could include an S5 tunnel between an SGW and PGW and an IP address assignment. And upon UE attachment, an MME could readily signal with a base station to establish an S1-U tunnel for the UE, and to convey the IP address assignment to the UE, without having to wait for establishment of the S5 tunnel and assignment of the IP address, and the MME could further signal with the SGW to cause the S5 tunnel and IP address assignment to be made UE specific and to tie the S5 tunnel with the newly established S1-U tunnel. Further, the quantity and service level of connections pre-established could be based on historical trends.
