Abstract: A first network node has first antenna nodes located along a track and associated with a first cell. Some of them serve a first cell overlap region that overlaps a second cell overlap region of second antenna nodes connected to a second network node. Some first antenna nodes form downlink beams in a same direction with power levels controlled such that respective amounts of overlap between the downlink beams and respective power levels of the downlink beams jointly cause the first cell's overlap region to emulate a cell border for a user equipment travelling at high speed. Emulated cell border signal power is lower at locations closer to an emulated cell outer edge than at more distant locations. Emulated cell border length is sufficient to cause the travelling user equipment to be within the emulated cell border long enough to successfully perform a handover between the first and second cells.

Abstract: Disclosed is a method and system to manage paging channels in a wireless communication network. When the network encounters a situation where the network is to transmit an access response message in a coverage area to a mobile station, the network will determine whether the mobile station is in an access handoff state. If not, the network will transmit the message to the mobile station on a paging channel selected based on the mobile station's identifier. Otherwise, the network will transmit the message to the mobile station on both that paging channel and a default paging channel (e.g., primary channel) selected without consideration of the mobile station's identifier. This process can help avoid an access handoff failure. Further, a radio access network may opt to use the default paging channel in response to the wireless coverage area having a different number of paging channels than an adjacent coverage area.
